American racism and African diplomats: race and American Cold War policy in West Africa  

E-Print Network (OSTI)

Two of the most significant influences on post-World War II American society were Cold War ideology and the struggle over civil rights. The Kennedy years provide a special opportunity to examine the relationship between these two facets of modern American society. The interconnectedness between Cold War ideology and civil rights increased during the 1960s. Cold War tensions escalated and the American government became increasingly concerned about the effect of racial strife on the country's image abroad. Many officials feared that America's racial problems placed her in a weaker position than the Soviet Union in the struggle to win the "hearts and minds" of Latin America, Asia, and Africa. This study will examine the political and social ramifications of the experiences of African diplomats in the United States during the Kennedy administration within both a national and international context. African encounters with American racism illustrate the interplay between foreign policy and domestic pressures and the globalization of the civil rights movement. The Kennedy administration, especially the State Department, took decisive action on the behalf of the African diplomats. However, racial problems confronting the African diplomats could not be resolved without resolving the racial problems confronting black Americans and other people of color in the United States. The main argument of this thesis is that the administration's efforts to solve this international image problem were significant steps towards the eventual end of de jure segregation in the long-term. This thesis includes an examination of relations between the United States and British West Africa, the African and Soviet response to American racism, the efforts of the State Department on behalf of the mistreated African diplomats, and the relationship between the civil rights movement and independence movements in Africa.

Black and white: a portrayal of gender roles in American women's periodicals during the Eisenhour years  

E-Print Network (OSTI)

This thesis examines how the media portrayed gender roles in periodical articles from 1953 to 1961. Magazines researched were those most widely read by white and black women. The purpose is to compare and contrast the views of white and black females concerning domesticity, education, career, children, sex, communism, and civil rights. This research found that periodicals promoted domesticity for white women between 1953 and 1957, and then became more interested writing about education and careers outside the home. On the other hand, periodicals aimed at African American women wrote about education and careers until 1957, and then began writing more about domesticity.

African American Fathersí Perceptions of Childhood Overweight: An Exploratory Study  

E-Print Network (OSTI)

Childhood overweight/obesity (CHO) is a serious health concern for children and adolescents. Despite increased efforts to prevent CHO, prevalence rates have actually increased. Evidence suggests that parents are critical to successful interventions to reduce CHO among children. While research efforts aimed at parental inclusion have increased, limited research has been conducted to investigate fathersí perception of CHO, or their influences on their childrenís health. The objective of this two-phase study was to answer three research questions: a) How does the extant literature operationalize African American parental perceptions of childhood overweight/obesity? b) What are African American fathersí perceptions of CHO? and c) How do African American fathers perceive CHO in relation to their own childís weight status? Evidence-based studies reveal that fathers have the potential to play a significant role in CHO prevention. Phase one (literature review) revealed that published studies on parental perception of CHO either exclude fathers, include them only in data collection, and/or report no results specific to paternal perception. Thus, an exploratory qualitative study was needed to explore African American fathersí perceptions of CHO. In phase two (qualitative study), four fathers were interviewed about their perceptions of CHO and how they contextualize this problem. The results indicated fathers believe that weight categories are racially & culturally insensitive and do not account for individual health status or differences in body/bone structure, and that parents with overweight children are financially disadvantaged, irresponsible and overworked. Fathers also indicated that colloquial terms (e.g., chunky, husky, big-boned, thick) were commonly substituted medical definitions for overweight and that child/teen sports participation was motivated by health, as well as non-health related benefits (e.g., competitiveness, educational scholarships). Further, fathersí identification of CHO is subjective and includes visual means and parental assessment of health status (e.g., child mobility/activity levels). Implications of this study are that additional studies are needed to clarify fathersí roles in CHO and that future studies should consider complex familial structures, as well as reframe prevention efforts to focus on optimal child health as opposed to weight labeling and focusing on parentsí accuracy in identifying weight categories.

School racial composition and academic performance of african american students in an urban school district  

E-Print Network (OSTI)

The purpose of this study was to investigate the differences in the academic performance of economically disadvantaged African-American students attending schools with distinct racial composition in selected inner-city Texas high schools based on the information available in the Academic Excellence Indicator System (AEIS) database. The degree to which certain schoolsí racial compositions may impact the achievement of economically disadvantaged African-American students was explored. The study was conducted in order examine the academic performance of economically disadvantaged African-American student groups in three large, comprehensive high schools with distinct ratios of school racial compositions. The analyses of student performance data in these three educational settings over three years offers insight into whether school racial composition affects the academic achievement of economically disadvantaged African-American students. A quantitative, two factor factorial (with repeat on the last factor) design was used to answer the questions posed. A mixed-model analysis of variance (ANOVA) was employed to analyze school and student level differences between the percentage of minority students in a school and the academic outcomes. Specifically, the reading and mathematics TAKS scores of economically disadvantaged African-American students from three high schools with distinct ratios of school racial composition were compared and analyzed. The final sample included 428 African-American students. The first school had a racial composition of 80/20, with African-Americans being the minority. The second school had a balanced racial composition (defined as ď30/30/30Ē), and the third schoolís racial composition was 30/70, with African-Americans being the majority. The most important finding in this study is that the differences in the reading and math performance of economically disadvantage African-American high school students attending schools with different racial composition are statistically significant. The researcher observed an increase in the average academic performance of African- American students as the concentration of minority students in the schools was reduced. Although the effect of school racial composition was minimal, the findings indicate that (even after controlling the effects of schools and studentsí demographic factors by holding these variables constant) reading and math TAKS scores were consistently higher in the 80/20 school than in the 30/30/30 school, followed by the 30/70 school.

Facing Racism at 30,000 Feet: African American Pilots, Flight Attendants, and Emotional Labor  

E-Print Network (OSTI)

In this qualitative study, I examine the experiences of African American pilots and flight attendants with emotional labor. Integral to existing theories of emotional labor is the incorporation of voices of color and their contemporary movement into professional industries. Essentially, most all theories of emotional labor were built through the examination of low-wage service workers in gendered or racially segregated occupations, with only recent incorporations of gendered occupations within professional settings. Using the theoretical concept of emotional labor, or the labor required to reduce or suppress feeling in order to sustain the outward countenance that produces the proper state of mind in others, I argue that emotional labor is much more than labor produced within the confines of a job, but is also based on identity characteristics that directly influence interactions in the workplace. Therefore, I qualitatively examine, through in-depth interviews with more than thirty African American flight crew members, how emotional labor is influenced and performed when people of color are introduced to professional settings. The results of this study show that there are multiple dimensions of emotional labor that should be added to existing theory. Primarily, existing standards of emotional labor in the airline industry are a direct result of institutional structures and cultures created during a period of systematic exclusion that do not account for contemporary racism and sexism. Thus, performing emotional labor in this industry is unequally placed on those white women and people of color that had no input into its creation. The results of this study suggest that emotional labor should be inclusive of systemic racism perspectives as a method of understanding how salient identity characteristics, such as gender, race, and class, are directly connected to preconceived ideologies that influence interactions that call for emotional labor. Moreover, because African American men and women in this industry are underrepresented, emotional labor becomes a necessity in their interactions with coworkers, consumers, and management. In addition, African Americans experience highly regulated emotional labor that influence how they perform their jobs, interact with others, and formulate appropriate counter-narratives.

Black Americans reduce the racial IQ gap: Evidence from standardization samples  

E-Print Network (OSTI)

the University of Virginia for helpful comment. 2 It is often asserted that blacks have made no IQ gains on whites, despite relative environmental gains, and that this adds credibility to the case that the black/white IQ gap has genetic origins. Until recently, there have been no adequate data to measure black IQ trends. We analyze data from nine standardization samples for four major tests of cognitive ability. These suggest that blacks have gained 5 or 6 IQ points on non-Hispanic whites between 1972 and 2002. Gains have been fairly uniform across the entire range of black cognitive ability. Philippe Rushton and Arthur Jensen (2005) state that the IQ difference between black and white Americans stands at 1.1 standard deviations (SDs) and is as large today as it was nearly 100 years ago. No one really knows the history of the black/white gap. Estimates for 1917 and 1943 are based on military data subject to a host of biases. Estimates since 1945 are based almost entirely on averaging studies, none of which compare nationally representative samples taking the same test administered at two different times (Herrnstein & Murray, 1994). Flynn (1987) analyzed military data and found that blacks

Recruiting African American Male Teachers in K-12 Schools: A Case Study in One Urban School District  

E-Print Network (OSTI)

A case study of the experiences of six African American male teachers in a southern K-12 school district is presented in this study. The purpose of this study was: 1) to hear the voices of African American male teachers in a selected urban school district; 2) to identify the factors that contribute to their job acceptance decisions; 3) to gain an in-depth understanding of why teachers chose teaching as a profession; 4) to determine and understand the nature of the professional lives of these teachers; and finally, 5) to advance our existing knowledge base in attracting African American males to our nation's classrooms. The data collection process consisted of one-on-one, open-ended interview questions with six highly qualified African American male public school teachers in a K-12 school district in the Southern region of the United States. The key themes which emerged through data analysis include: (1) nobility associated with the teaching profession; (2) compassion associated with the teaching profession; (3) stability associated with the teaching profession; (4) family and community influences; (5) life experiences and (6) I was not recruited: I chose this district. Ethic of Care and Critical Race theoretical frameworks were the foundation for the study.

Weight-related Beliefs, Behaviors, and Social Networks of Obese, Young Adult African- American Women: Implications for Healthy Weight Interventions  

E-Print Network (OSTI)

Obesity is a public health concern that affects over 30% of Americans. Approximately 78% of African-American women are overweight/obese, as compared to 46% of Caucasian women. Obese African-American women are at higher risk for associated morbidities (e.g., hypertension, type II diabetes, select cancers, and early mortality) as compared to non-Hispanic whites. Weight gain after young adulthood (ages 20-35) is associated with an increased risk of cardiovascular disease and other health problems later in life. Research that seeks to explain, predict, or control obesity among African-American women has focused on individual behavior change. Few studies have addressed the social contexts within which these behaviors occur. The purpose of this exploratory study was to examine the weight-related beliefs, behaviors, and social network characteristics of obese, young adult African-American women. A conceptual framework based on social support and social network theory guided the design of the study. Ten African-American women between the ages of 20 and 35, self-described as ďplus-sizeĒ or ďfull-figured,Ē completed initial informal conversations about weight-related issues and concerns and semi-structured, in-depth face-to-face interviews. Five participants were randomly selected to complete social network profiles to identify potential social influences on weight-related beliefs and behaviors. Results of the initial conversations revealed approximately half of the participants were class III obesity (BMI > 40), reported overall good health, and 70% participated in physical activity at least one day a week. Semi-structured interviews results disclosed two primary reasons for unsuccessful long-term weight loss: (a) inconsistent weight loss behaviors and (b) lack of accountability. Weight-related beliefs and behaviors of study participants were similar to those reported for older adult African-American women. Similarities included (a) mixed levels of body satisfaction; (b) the belief that health is not determined by weight; (c) sedentary lifestyles and; (d) social support from family and friends impacts long-term weight loss success. The five social network profiles indicated participantsí networks are small, comprised of at least two overweight/obese females, and exhibited positive social support behaviors. Social networks included positive, negative, and non-positive relationships. Social support for weight loss is shared among network members through face-to-face interactions, phone conversations, and use of social media tools such as Facebook, Twitter, and text messaging. Future healthy weight studies would benefit from comprehensive analyses of the social networks of obese, young adult African-American women, inclusive of interviews with social network members. Culture-based healthier weight interventions that organize social support networks through social media tools are promising strategies for promoting healthy weight management among obese, young adult African-American women.

The Parental Investment of First-Generation African American Rural College Graduates in Cultivating College Student Success  

E-Print Network (OSTI)

This basic qualitative study examines the parental investment strategies of first-generation African American rural college graduates in cultivating college student success. Extant literature has demonstrated that the role of the family is necessary to support the college student and that the investment of the parent is paramount to student college completion. Although educational attainment is an important goal for African American rural residents, research detailing strategies that cultivated student college completion among this population is needed to fill the gaps in the literature. The objectives were to discuss communication, involvement, and factors of influence to determine how these parents transferred their educational beliefs to their children and supported them through college graduation. These stories of success were told through the eyes of first-generation parents and their second-generation adult offspring. Research detailing the parental investment strategies toward college completion is necessary to inform parents, educational institutions, and rural college student completion in postsecondary institutions of the strategies necessary to ensure college success in this population. Liebermanís transgenerational theory, along with concepts extracted from parental investment as it relates to education, provided the conceptual lens for the study. Data collected through interviews and documents were analyzed utilizing content analysis. Ten semistructured interviews were conducted with parents and their adult offspring. Interviews gleaned the lived experiences of the participants. Data analysis revealed six themes: (a) Catch Them Early, (b) Set the Tone, (c) Keep Them Busy, (d) Donít Let Them ďBreak Rank,Ē (e) Encourage Advancement, and (f) Tell the Generations. The findings support the importance of developing a family investment team, how a return on parental investment occurs, making use of rural extracurricular programming, and transferring positive beliefs regarding higher education.

Distribution of toenail selenium levels in young adult Caucasians and African Americans in the United States: The CARDIA Trace Element Study  

SciTech Connect

Background: Data on selenium (Se) levels in American young adults, especially in African Americans, are lacking. Objective: This study presented toenail Se distributions in American young adults of both genders, including both Caucasians and African Americans; and explored potential predictors of toenail Se levels. Data and methods: Data from the Coronary Artery Risk Development in Young Adults study among 4252 American young adults, aged 20-32 in 1987 was used to examine toenail Se levels by instrumental neutron-activation analysis. The distribution of Se levels was described and multivariable linear regression was used to examine potential modifiers of toenail Se concentration within ethnicity-gender subgroups. Results: The geometric mean of toenail Se in this cohort was 0.844 {mu}g/g (95% CI, 0.840-0.849 {mu}g/g) and the median was 0.837 {mu}g/g (95% CI, 0.833-0.844 {mu}g/g). Median levels from lowest to highest quintile were 0.691, 0.774, 0.838, 0.913 and 1.037 {mu}g/g. Se levels varied geographically, and were generally in accordance with its concentrations in local soil. Males, African Americans, current smokers, heavy drinkers and less educated participants were more likely to have low Se levels. Conclusion: This study suggests that toenail Se levels vary geographically depending on soil Se concentrations. In addition to gender, ethnicity and education level, smoking status and alcohol consumption are two important indicators of Se status since they are modifiable lifestyle factors. Findings from this study might aid public health professionals in identifying people at relatively high or low Se levels, so that chronic disease prevention efforts can be directed toward these subgroups. - Research highlights: {yields} Average of toenail Se levels in this cohort was 0.844 {mu}g/g (95% CI, 0.840-0.849 {mu}g/g). {yields} Toenail Se levels vary geographically depending on soil Se concentrations. {yields} Males, African Americans and less educated participants have low Se levels. {yields} Smoking status and alcohol consumption are two important indicators of Se status.

Understanding curriculum in context: using currere to explore the perceptions, attitudes and practices of white teachers in classrooms with african american students  

E-Print Network (OSTI)

As a careful look into the daily lived experiences of teachers in todayís schools, the overarching purpose of this study was to seek a clearer understanding of how race may be reflected in the construction of teachersí perceptions and practices. More specifically, the intent was to understand the relationship between the selected White teachersí perceptions of themselves as White educators, their perceptions of the African American students they teach, and their teaching practices. Further, this research also sought to explore the potential and possibilities for engaging currere, as defined in Pinarís 1976 work, as a method of study in educational research. With this in mind, this study was not only a journey to explore the complexities in classrooms of selected White teachers and their African American students; it also became a complicated process of self-excavation and deconstruction of myself, a former White teacher of African American students. A qualitative methodology, guided by critical epistemologies was used. The researcher, acted as participant observer. The research included four components: teacher interviews, classroom observations, informal dialogue, and teacher reflection. Four significant instructional practices and interactions emerged from classroom observations that seemed to reflect the relationship between selected White teachersí perceptions of themselves and the African American students they teach. These were: (1) overcorrection and inconsistent (re)direction, (2) failure to engage, (3) isolation and dismissal, and (4) lowered expectations and lesser curriculum. While the research in education has identified similar themes and practices, when viewed in and through the context of currere, a greater complexity in classrooms with White teachers and African American students is exposed. Currere holds that each of us is a manifestation of our past and that in order to realize any semblance of meaningful, authentic progress in the future, each of us must first examine our past, our perceptions and our ways of knowing and being in the world. Currere offers us a method by which to begin this journey Ė as individuals, as a collective society, and certainly as teachers.

Elementary Special Education Teachers' Cultural Awareness and Beliefs In One Urban School District Regarding African American Learners  

E-Print Network (OSTI)

Today's urban schools are composed of students from diverse cultural backgrounds and varying levels of academic readiness. At the same time, approximately 88% of teachers are White and middle-class. The dispositions of teachers have important educational ramifications. Teachers' beliefs structure the classroom atmosphere, influence perceptions regarding the abilities of students, and impact how they teach and expect students to learn and behave. In order to foster an accepting and productive learning environment, teachers must have cultural awareness. To ensure that all learners receive a solid academic foundation, teachers must be able to instruct dissimilar students. Special educators have been trained to work with students with unique, special needs, but the reality of today's demographics - and special education classrooms in particular - mandate that they also have the cultural knowledge to effectively serve diverse students. Perceptions and attitudes of elementary special education teachers regarding their cultural awareness and beliefs need to be explored. This study examined the cultural awareness beliefs of elementary special educators working in urban school districts located in southeast Texas. The research also needs to ascertain whether ethnicity or length of service effected such teachers' cultural awareness beliefs. Using the Cultural Awareness Beliefs Inventory (CABI) instrument, the investigator gathered self-reported data from 54 participants. The reliability and validity of the instrument were determined to be sound by previous investigators. The CABI contains eight major components: Teacher Beliefs, School Climate, Culturally Responsive Classroom Management, Home and Community Support, Curriculum and Instruction, Cultural Sensitivity, Cultural Awareness, and Teacher Efficacy. Data were analyzed using percentage analysis and one-way analysis of variance. The findings include: 1) Participants had favorable perceptions towards the School Climate, Culturally Responsive Classroom Management, and Cultural Awareness variables; 2) Participants had unfavorable perceptions regarding Teacher Beliefs; 3) In contrast to some previous research, it did not appear that teaching experience impacted cultural beliefs; and 4) Importantly, it was discerned that teachers' ethnicities yielded statistically significant effects on their cultural awareness and beliefs regarding African American special education students.

Not a One-Way Street: Exploring the Role of Intersectional Representation on African American Male Students  

E-Print Network (OSTI)

Representation is an enduring area of research in Political Science. While there has been an extensive amount of research in the area of minority representation, there is substantially less work considering multiple identities. Using the concept of intersectionality, this dissertation explores the role of multiple identities in representation. I argue that intersectional representation, that is, representation based on multiple identities provides a thorough interpretation of real world phenomena. To test my arguments, I utilize quantitative methods to empirically assess the role of intersectional representation on public policy outcomes. The goal of this dissertation is three-fold. First, I incorporate the concept of intersectionality of race and gender into the public policy and public management literature. Second, I explore intersectionality and representation with gender from a perspective that has not been extensively addressed in the political science literatureónamely, a concentration on males, instead of females. Third, I develop a theory of intersectional representation which links to public policy outcomes. In order to test my theory, I explore the role of Black male representation in the bureaucracy and in local political bodies on Black male student outcomes. I find that representation based on both race and gender is associated with both positive and negative public policy outcomes for Black male students. Specifically, in Chapter I, the results indicate that Black male teachers are associated with a decreased presence of Black male students in low tracked courses and upper level honors courses. The following chapter shows that intersectional political representation, that is, Black male school board representation, is also associated with positive outcomes for Black male students. The last empirical chapter indicates that intersectional stability is associated with an increase of Black male students in low track courses. In general, the findings indicate that intersectional representation is consequential for public policy outcomes, both in negative and positive ways. The dissertation challenges the way representation is conceptualized, as to capture the simultaneous effect of both race and gender on public policy outcomes of represented groups.

Reclaiming Blackness: (Counter) Narratives of Racial Kinship in Black Gay MenĎs Sexual Stories  

E-Print Network (OSTI)

Black gay male identities and their place within the social hierarchy are organized by interlocking systems of race, sexuality, gender and class. This produces the social marginality of black gay men in seemingly neutral ways. Prominent features of this systemic oppression are stock stories of black gay life that construct black gay men as pathological, dangerous, conflicted, inauthentically black, emasculated, and heretical within public and academic discourses. In order to better understand these dynamics and add to the empirical literature on race/sexuality intersections, fifty-two men identifying themselves as black/African American and as having relationships with other men, participated in semi-structured one-on-one interviews which explored their accounts of the structural arrangements, social interactions, and cultural meaning systems that defined the experience of being both black and gay in America. These interviews revealed that black gay men construct rich and complex counter narratives which not only expose the complex structural arrangements, cultural practices and racial ideologies that produce their marginality, but also remediate black gay manhood as part of the black diaspora. These narrative challenges illuminated discursive, performative and cultural practices, as well as social interactions occurring in three areas of the menĎs lives. First, were strategic uses of a hegemonic masculine form I call the "Super Black Man" (SBM) by which the men counteract the heteronormative, and hypermasculine prerequisites of respectable black masculinity, and represent themselves as racially-conscious and respectable black men. Participants also constructed narrative challenges to those cultural repertoires produced by the black church which organize the dominant scripts of black, Christian identity. These accounts were distinguished by the academic resources they utilized to re-theorize the relationship between Christian faith and the black body, confront the white racial framing and heteronormative assumptions embedded in church doctrine, and transform their outsider status within these communities. Finally participantsĎ narratives also illustrate multiple dimensions by which a black racial framing organizes their experiences as black gay men, and their connection to black communities. These negotiations suggest the need to theorize race/sexuality intersections as having both structural and interpretative dimensions and to see the intersection of race and culture as complicating the manifestation of racial inequality.

Head black woman in charge: An investigation of how black female athletic directors negotiate their race, gender, and class identities  

E-Print Network (OSTI)

Framed as an instrumental case study, the purpose of this investigation was to understand how a select group of women, Black female athletic directors, define and negotiate their race, gender, and class identities. Data was collected via a qualitative indepth semi-structured interview methodology. The women who were chosen for this research are Black female athletic directors of NCAA Division I, II, and III intercollegiate athletic departments. The data analysis consisted of coding the data at two levels: first-level coding and pattern coding, and following the coding process, the emergent findings were compared with the identity negotiation theory (i.e. selfverification and behavioral confirmation processes) in order to understand how the Black female athletic directors negotiated their race, gender, and class identities. This investigation found that Black women athletic directors used two different denotations (i.e. African American and Black) to reference their racial identity, and race was the most salient identity because of their upbringings, childhood experiences, and dealings with racism. All of the women are heterosexual, but insufficient data did not allow a full understanding how they define their gender identity. In describing their class status, the majority of the women came from a traditionally defined lower socioeconomic class background, but as a result of their athletic director appointment they now reside in the middle or upper middle economic class status. In understanding how Black female athletic directors negotiate their identities within and outside the athletic department, and what factors are associated with the negotiation of their identities, this investigation found that the Black women athletic directors had to establish, maintain, and change their race, gender, and class identities with the utilization of various self-verification and behavioral confirmation strategies. These negotiations were conducted in response to the expectations that ensued as a result of their role in a leadership position, lesbian, intra- and inter-racial interactions, and exposure to lesbian, Mammy, and Sapphire stereotypes.

Black/brown cooperation and conflict in the education policymaking process  

E-Print Network (OSTI)

The way race works to shape politics is changing as demographic patterns alter the traditional dynamic of race relations throughout the United States. One pattern is the increased tendency of African-Americans and Latinos to reside in the same locality. While popular opinion suggests that such contexts should result in the formation of √ʬ?¬?rainbow coalitions,√ʬ?¬Ě several scholars have found evidence that inter-minority relations are characterized by high levels of political competition. One of the policy areas in which competition has been observed most often is education. This dissertation examines the conditions under which African-American/Latino relations are likely to be characterized by cooperation or conflict within the education policymaking process. It utilizes a survey of 1800 school districts, containing 96% of all urban districts in the United States. The results produced by this study, therefore, are applicable to nearly the entire universe of urban educational systems. Another unique aspect of this project is that, rather than focusing on relations at one stage of the policy process, it attempts to trace this dynamic through each stage. Thus, the dissertation begins with a look at the circumstances under which Black/Brown electoral coalitions will form in school board elections. The findings suggest that coalition formation is contingent upon structural contexts, specifically the presence of partisan elections, and upon the citizenship status of the Latino population within a district. The dissertation goes on to trace the cooperative and competitive forces that affect the hiring of African- American and Latino administrators and teachers. Lastly, I use theories of bureaucratic politics and racial context to study the quality of education received by minority students. I find that, controlling for other factors, more diverse school districts have more equitable educational policies. I also find evidence to support the contention that more diverse teaching faculties tend to result in beneficial outcomes for both African- American and Latino students.

"we have . . . kept the negroes' goodwill and sent them away": black sailors, white dominion in the new navy, 1893-1942  

E-Print Network (OSTI)

Between 1893 and 1920 the rising tide of racial antagonism and discrimination that swept America fundamentally altered racial relations in the United States Navy. African Americans, an integral part of the enlisted force since the Revolutionary War, found their labor devalued and opportunities for participation and promotion curtailed as civilian leaders and white naval personnel made repeated attempts to exclude blacks from the service. Between 1920 and 1942 the few black sailors who remained in the navy found few opportunities. The development of Jim Crow in the U.S. Navy occurred in three phases. During the first, between 1893 and 1919, a de facto policy excluded African Americans from all ratings save those of the messman's branch. The second major phase began in April 1919 with the cessation of domestic enlistments in the messmanís branch. The meant the effective exclusion of blacks, as the navy had previously limited them to this one area of service. Between World War I and 1933 thousands of East Asians enlisted as messmen and stewards, replacing native-born Americans. The third phase, between 1933 and 1942, represented a qualified step forward for blacks as the navy again began to recruit them, though it limited them to the messman branch. In their circumscribed roles on board ship, black messmen and stewards suffered discrimination and possessed few opportunities for advancement. In the late-1930ís and early-1940ís public figures, including prominent leaders of the African American community, charged the navy, army, and defense industries with practicing racial discrimination. The navy, reflecting its general conservatism, responded slowly to demands for change. By 1942, however, the navy began detailing black men to billets outside the messmanís branch, a first step away from Jim Crowstyle policies. This thesis analyzes the evolution of discriminatory and exclusionary enlistment policies in the navy. While others have provided the basic outline of segregation in the navy, this thesis provides a more complete analysis of the navyís actions in the context of wider American society. This thesis also confirms that the navy was a slow-moving actor which followed the societyís lead and did not substantially revise existing racial hierarchy.

Slow, clumsy and loose-jointed in appearance, with a shambling gait, he can be very swift and nimble. Like any good clown he is also a good acrobat with a fine sense of balance and timing. He is a great climber in spite of his bulk. Shrewd and droll, he is very popular in menageries and as a performer in circuses and side shows because he learns tricks easily. He can stand on his hind legs to wrestle, box, dance, or beg for food and, occasionally, one becomes a graceful artist on roller skates. They love applause.

The Hartle-Hawking state of $\\mathcal{N}=4$ SYM at strong coupling and large $N$ on a fixed black hole background has two proposed gravitational duals: a black funnel or a black droplet. We construct the black funnel solutions that are dual to the Hartle-Hawking state on a Schwarzschild black hole and on a class of three-dimensional asymptotically flat black hole backgrounds. We compute their holographic stress tensor and argue for the stability of these solutions.

Report on student participants at the 2003 Annual Meeting of the National Society of Black Physicists  

SciTech Connect

The first meeting of African American physicists was held in 1973 at Fisk University in Nashville, Tennessee, with around 50 Black physicists in attendance. In 1977, this organization was formally established as the National Society of Black Physicists (NSBP) out of a need to address many concerns of African American physicists. During the ensuing years the Conference began to grow and was hosted by different institutions at various geographic locations. This year, the 2003 Annual Conference of the National Society of Black Physicists and Black Physics Students was hosted by Spelman College in Atlanta, Georgia during the weekend of February 12th-15th, 2003. This Conference brought together over 500 African American physics students and working physicists. Also attending were corporate and graduate school recruiters, administrators, professional society representatives and others concerned with the small representation of minorities in the field of physics. The organizers of the Conference contracted with the Statistical Research Center of the American Institute of Physics to conduct a formal evaluative study of the meeting, resulting in this report. The evaluation questionnaire was designed by the organizers of the NSBP conference with input from the Statistical Research Center's staff. It included questions on the students' backgrounds and demographic characteristics, physics research experience, career goals, challenges faced in their academic pursuits, and ratings of various aspects of the conference. The questionnaire was distributed at the conference when the students signed in. Of the 330 students who were registered, roughly 304 attended and were given the four-page questionnaire to complete. Responses were collected on the last night of the conference, with 172 (approximately 57%) returning completed questionnaires. This low response rate could be attributed in part to the fact that respondents were asked to provide possibly sensitive personal information. Student participants at the conference were asked to provide data on various aspects of their backgrounds and demographic characteristics. We found that there were significantly more undergraduate participants than graduate participants present at the conference (65% versus 35%). More than two-thirds of the undergraduate student attendees were upperclassmen. On the other hand, close to half of the graduate student attendees were still in the early stages of their graduate career. The overall median age was 23 years. The median age for undergraduates was 21, while for graduate students it was 29 years. We found no age difference between undergraduate males and females. However, there was an age difference between graduate male and female students. While among females the median age was 27, for graduate males the median age was 30 years. As shown, we see that women were well represented at this year's conference. The overall proportion of female student respondents was 41%. Among undergraduates, the proportion of females was 48%. While comparable data on all Black physics students nationwide are not available, this number bachelors recipients going to women, as reported by Historically Black Colleges and Universities (HBCUs) on AIP's most recent ''Enrollments and Degrees Study''. HBCUs confer more than half of all physics degrees by African-Americans in the US. The proportion of females among graduate student participants at the NSBP conference was 29%.

The effect of urinary cadmium on cardiovascular fitness as measured by VO{sub 2} max in white, black and Mexican Americans  

SciTech Connect

Objectives: We explored potential effects of cadmium exposure on cardiovascular fitness measures, including gender and racial/ethnic differences. Methods: Data were from the 1999 to 2000 National Health and Nutrition Examination Survey (NHANES); 1963 participating subjects were included in our analysis. Volume of oxygen consumed at sub-maximum activity (VO{sub 2} max) were recorded in a series of graded exercises; the goal was to elicit 75% of predetermined age-specific heart rates. Cadmium from urine samples was measured in the laboratory using standard methods. Multivariate linear regression analyses were performed to determine potential relationships. Results: Increased urinary cadmium concentrations were generally associated with decreased estimated VO{sub 2} max values. Gender and racial/ethnic differences were also observed. Specifically, associations were statistically significant for white males and Mexican American females. Conclusion: Inverse associations between urinary cadmium concentrations and estimated VO{sub 2} max values were observed, including racial and gender differences. The implications of such gender and racial/ethnic differences on long-term cardiovascular health and health disparities of present public health concern warrant further investigation.

Americans Americans Nature Bulletin No. 360-A November 29, 1969 Forest Preserve District of Cook County George W. Dunne, President Roland F. Eisenbeis, Supt. of Conservation THE FIRST AMERICANS When the Norsemen and then Columbus "discovered" America they found people here -- people with bronze skins and straight black hair. Because he thought he had sailed across the world and found a sea passage to India. Columbus called these people "Indios". He was wrong but we still call them Indians. It is now generally accepted by scientists that the first humans arrived on this American continent some thirty or forty thousand years ago. It is believed that they came from Asia, across what we call Bering Strait. The distance from the islands at the westernmost tip of Alaska to the easternmost tip of Siberia is only 59 miles. In clear weather you can see from land to land. In ancient times there may have been a bridge of solid ice between the two shores, or there might have been an actual land connection between the two continents. But even if there were a 5-mile gap of water it could have been crossed in primitive canoes by hungry people hunting for game. Hunger has been the mainspring of civilization.

E-Print Network (OSTI)

The main focus of this session was the presentation of new higher-dimensional black hole solutions, including black rings, black strings, and multi black holes, and the study of their properties. Besides new asymptotically flat and locally asymptotically flat black objects also new black holes with anti-de Sitter asymptotics were reported. The studies of their properties included the investigation of their stability, their thermodynamics, their analyticity and their existence. Furthermore, the geodesics in such higher-dimensional space-times were investigated.

The National Society of Black Physicists will hold its Twentieth annual meeting and its XXIIII Day of Scientific Lectures at Lawrence Berkeley National Laboratory on March 27th - 30th, 1997. The meeting provides a major opportunity for African American physicists and students to present their current research and discuss issues germane to the constituency. It is therefore crucial to have the broadest cross-section of the membership at each meeting. The Lawrence Berkeley National Laboratory was chosen as the site of the 20th annual meeting because of its historical significance to Physics (being one of the first national laboratories in the United States) and the laboratories continuing support of the goals and objectives of the society.

Black hole masking and black hole thermodynamics  

E-Print Network (OSTI)

Masking of black holes means that, for given total mass and Hawking temperatures, these data may correspond to either "pure" black hole or a black hole of a lesser mass surrounded by a massive shell. It is shown that there is one-to one correspondence between this phenomenon and thermodynamics of a black hole in a finite size cavity: masking of black holes is possible if and only if there exists at least one locally unstable black hole solution in the corresponding canonical ensemble.

Unity, Justice and Protection: The Colored Trainmen of America's Struggle to End Jim Crow in the American Railroad Industry [and Elsewhere  

E-Print Network (OSTI)

The Colored Trainmen of America (CTA) actively challenged Jim Crow policies on the job and in the public sphere between the 1930s and 1950s. In response to lingering questions concerning the relationship between early black labor activism and civil rights protest, this study goes beyond both local lure and cursory research. This study examines the Colored Trainmen's major contributions to the advancement of African Americans. It also provides context for some of the organization's shortcomings in both realms. On the job the African American railroad workers belonging to the CTA fought valiantly to receive the same opportunities for professional growth and development as whites working in the operating trades of the railroad industry. In the public sphere, these men collectively protested second-class services and accommodations both on and off the clock. Neither their agenda, the scope of their activities, nor their influence was limited to the railroad lines the members of the CTA operated within the Gulf Coast region. The CTA belonged to a progressive coalition comprised of four other powerful independent African American labor unions committed to unyielding labor activism and the toppling of Jim Crow. Together, they all worked to effectuate meaningful social change in partnership with national civil rights attorney Charles H. Houston. Houston's experience and direction, coupled with the CTA's dedicated membership and willingness to challenge authority, created considerable momentum in movements aimed at toppling racial inequality in the workplace and elsewhere. Like most of their predecessors, the CTA's struggle for advancement fits within a continuum of successive challenges to economic exploitation and racial inequality. No single person or organization can take full credit for ending segregation or achieving equality. Many who remain nameless and faceless contributed and sacrificed. This study not only chronicles the contribution of a relatively unsung African American labor organization that waged war against Jim Crow on two different fronts, it also pays homage to a few more individuals who made a difference in the lives of an entire race of people during the course of a bitterly contested, never-ending struggle for racial equality in the United States of America during the twentieth century.

We present new supersymmetric solutions of five-dimensional minimal supergravity that describe concentric black rings with an optional black hole at the common centre. Configurations of two black rings are found which have the same conserved charges as a single rotating black hole; these black rings can have a total horizon area less than, equal to, or greater than the black hole with the same charges. A numerical investigation of these particular black ring solutions suggests that they do not have closed timelike curves.

Brane World Black Rings  

E-Print Network (OSTI)

Five dimensional neutral rotating black rings are described from a Randall-Sundrum brane world perspective in the bulk black string framework. To this end we consider a rotating black string extension of a five dimensional black ring into the bulk of a six dimensional Randall-Sundrum brane world with a single four brane. The bulk solution intercepts the four brane in a five dimensional black ring with the usual curvature singularity on the brane. The bulk geodesics restricted to the plane of rotation of the black ring are constructed and their projections on the four brane match with the usual black ring geodesics restricted to the same plane. The asymptotic nature of the bulk geodesics are elucidated with reference to a bulk singularity at the AdS horizon. We further discuss the description of a brane world black ring as a limit of a boosted bulk black 2 brane with periodic identification.

We give an exact description of the steady flow of a black string into a planar horizon. The event horizon is out of equilibrium and provides a simple, exact instance of a `flowing black funnel' in any dimension D>=5. It is also an approximation to a smooth intersection between a black string and a black hole, in the limit in which the black hole is much larger than the black string thickness. The construction extends easily to more general flows, in particular charged flows.

These compounds form in pore space between the seafloor and a sub-bottom depth where appropriate stability conditions prevail. However, the amount and distribution of gas hydrate within this zone, and free gas below, can vary significantly at different locations. To understand this variability, we develop a one-dimensional numerical model that simulates the accumulation of gas hydrates in marine sediments due to upward and downward fluxes of methane over time.

Inspired by the recent conjecture that black holes are condensates (of gravitons), we investigate a simple model for the black hole degrees of freedom that is consistent both from the point of view of Quantum mechanics and of General Relativity. Since the two perspectives should converge for small, Planck size, black holes, we expect our construction is useful for understanding the physics of microscopic, quantum black holes.

The postulates of black hole complementarity do not imply a firewall for infalling observers at a black hole horizon. The dynamics of the stretched horizon, that scrambles and re-emits information, determines whether infalling observers experience anything out of the ordinary when entering a large black hole. In particular, there is no firewall if the stretched horizon degrees of freedom retain information for a time of order the black hole scrambling time.

Phantom Black Holes  

E-Print Network (OSTI)

The exact solutions of electrically charged phantom black holes with the cosmological constant are constructed. They are labelled by the mass, the electrical charge, the cosmological constant and the coupling constant between the phantom and the Maxwell field. It is found that the phantom has important consequences on the properties of black holes. In particular, the extremal charged phantom black holes can never be achieved and so the third law of thermodynamics for black holes still holds. The cosmological aspects of the phantom black hole and phantom field are also briefly discussed.

The gravitational field of a black hole is so strong that Einstein's general relativity tells us that nothing, not even light, can escape from the black hole's interior. However, in 1974 physicist Stephen Hawking demonstrated that black holes must emit radiation once the quantum effects are included. According to quantum mechanics, the physical vacuum is bubbling with short-lived virtual particle-antiparticle pairs. Creation of a particle-antiparticle pair from the vacuum conflicts with energy conservation, but energy need not be conserved at short times in quantum mechanics, according to Heisenberg's

A Black Hole Levitron  

E-Print Network (OSTI)

We study the problem of spatially stabilising four dimensional extremal black holes in background electric/magnetic fields. Whilst looking for stationary stable solutions describing black holes kept in external fields we find that taking a continuum limit of Denef et al's multi-center solutions provides a supergravity description of such backgrounds within which a black hole can be trapped in a given volume. This is realised by levitating a black hole over a magnetic dipole base. We comment on how such a construction resembles a mechanical Levitron.

Black Hole Shadows of Charged Spinning Black Holes  

E-Print Network (OSTI)

We propose a method for measuring the black hole charge by imaging a black hole shadow in a galactic center by future interferometers. Even when the black hole is uncharged, it is possible to confirm the charge neutrality by this method. We first derive the analytic formulae of the black hole shadow in an optically thin medium around a charged spinning black hole, and then investigate how contours of the black hole shadow depend on the spin and the charge of the black hole for several inclination angles between the rotation axis of the black hole and the observer. This method only assumes stationary black hole and general relativity. By fitting the formula of the contours of the shadow to the observed image of the shadow, in addition to the black hole charge, one can also determine the black hole spin and the inclination angle without any degeneracy among the charge, the spin, and the inclination angle unless the inclination angle is null.

Black holes and beyond  

SciTech Connect

The black hole information paradox forces us into a strange situation: we must find a way to break the semiclassical approximation in a domain where no quantum gravity effects would normally be expected. Traditional quantizations of gravity do not exhibit any such breakdown, and this forces us into a difficult corner: either we must give up quantum mechanics or we must accept the existence of troublesome 'remnants'. In string theory, however, the fundamental quanta are extended objects, and it turns out that the bound states of such objects acquire a size that grows with the number of quanta in the bound state. The interior of the black hole gets completely altered to a 'fuzzball' structure, and information is able to escape in radiation from the hole. The semiclassical approximation can break at macroscopic scales due to the large entropy of the hole: the measure in the path integral competes with the classical action, instead of giving a subleading correction. Putting this picture of black hole microstates together with ideas about entangled states leads to a natural set of conjectures on many long-standing questions in gravity: the significance of Rindler and de Sitter entropies, the notion of black hole complementarity, and the fate of an observer falling into a black hole. - Highlights: Black-Right-Pointing-Pointer The information paradox is a serious problem. Black-Right-Pointing-Pointer To solve it we need to find 'hair' on black holes. Black-Right-Pointing-Pointer In string theory we find 'hair' by the fuzzball construction. Black-Right-Pointing-Pointer Fuzzballs help to resolve many other issues in gravity.

Evaluation of Black Carbon Estimations in Global Aerosol Models  

DOE Green Energy (OSTI)

We evaluate black carbon (BC) model predictions from the AeroCom model intercomparison project by considering the diversity among year 2000 model simulations and comparing model predictions with available measurements. These model-measurement intercomparisons include BC surface and aircraft concentrations, aerosol absorption optical depth (AAOD) from AERONET and OMI retrievals and BC column estimations based on AERONET. In regions other than Asia, most models are biased high compared to surface concentration measurements. However compared with (column) AAOD or BC burden retreivals, the models are generally biased low. The average ratio of model to retrieved AAOD is less than 0.7 in South American and 0.6 in African biomass burning regions; both of these regions lack surface concentration measurements. In Asia the average model to observed ratio is 0.6 for AAOD and 0.5 for BC surface concentrations. Compared with aircraft measurements over the Americas at latitudes between 0 and 50N, the average model is a factor of 10 larger than observed, and most models exceed the measured BC standard deviation in the mid to upper troposphere. At higher latitudes the average model to aircraft BC is 0.6 and underestimate the observed BC loading in the lower and middle troposphere associated with springtime Arctic haze. Low model bias for AAOD but overestimation of surface and upper atmospheric BC concentrations at lower latitudes suggests that most models are underestimating BC absorption and should improve estimates for refractive index, particle size, and optical effects of BC coating. Retrieval uncertainties and/or differences with model diagnostic treatment may also contribute to the model-measurement disparity. Largest AeroCom model diversity occurred in northern Eurasia and the remote Arctic, regions influenced by anthropogenic sources. Changing emissions, aging, removal, or optical properties within a single model generated a smaller change in model predictions than the range represented by the full set of AeroCom models. Upper tropospheric concentrations of BC mass from the aircraft measurements are suggested to provide a unique new benchmark to test scavenging and vertical dispersion of BC in global models.

In 2008, African swine fever was introduced into Georgia, after which it spread to neighboring Armenia, Azerbaijan, and the Russian Federation. That same year, PCR and sequence analysis identifi ed African swine fever virus in samples from 3 dead female wild boars in northwestern Iran. Wild boars may serve as a reservoir. African swine fever (ASF) is a notifiable, highly contagious, lethal, hemorrhagic disease in domestic pigs (1,2). ASF virus (ASFV) (International Committee on Taxonomy of Viruses database no. 00.002.0.01.001), an enveloped double-stranded DNA virus, is the only known DNA arbovirus (3). Maintenance and transmission of ASFV involves cycling of virus between soft ticks of the genus Ornithodoros and wild pigs (warthogs, bush pigs, and giant forest boars) (1,2).

In this place we show some characteristics of the solutions of five dimensional black di-rings, especially in thermodynamic equilibrium. After the summary of the di-ring expressions and their physical quantities, first we comment on the equivalence of the two different solution sets of the black di-rings. Then the existence of thermodynamic black di-rings is shown, in which both isothermality and isorotation between the inner black ring and the outer black ring are realized. We also give detailed analysis of peculiar properties of the thermodynamic black di-ring including discussion about a certain kind of thermodynamic stability (instability) of the system.

We argue that in the high energy QCD a true black disk wave function necessarily contains many quarks. This corresponds to necessity of non-vacuum reggeon loops in formation of a black disk. The result comes from decomposition of the black disk S-matrix in characters on group manifold.

Black holes and black strings in plane waves  

E-Print Network (OSTI)

We investigate the construction of black holes and black strings in vacuum plane wave spacetimes using the method of matched asymptotic expansions. We find solutions of the linearised equations of motion in the asymptotic region for a general source on a plane wave background. We observe that these solutions do not satisfy our previously defined conditions for being asymptotically plane wave. We consider the solution in the near region, treating the plane wave as a perturbation of a black object, and find that there is a regular black string solution but no regular black hole solution.

Gasification of black liquor  

DOE Patents (OSTI)

A concentrated aqueous black liquor containing carbonaceous material and alkali metal sulfur compounds is treated in a gasifier vessel containing a relatively shallow molten salt pool at its bottom to form a combustible gas and a sulfide-rich melt. The gasifier vessel, which is preferably pressurized, has a black liquor drying zone at its upper part, a black liquor solids gasification zone located below the drying zone, and a molten salt sulfur reduction zone which comprises the molten salt pool. A first portion of an oxygen-containing gas is introduced into the gas space in the gasification zone immediately above the molten salt pool. The remainder of the oxygen-containing gas is introduced into the molten salt pool in an amount sufficient to cause gasification of carbonaceous material entering the pool from the gasification zone but not sufficient to create oxidizing conditions in the pool. The total amount of the oxygen-containing gas introduced both above the pool and into the pool constitutes between 25 and 55% of the amount required for complete combustion of the black liquor feed. A combustible gas is withdrawn from an upper portion of the drying zone, and a melt in which the sulfur content is predominantly in the form of alkali metal sulfide is withdrawn from the molten salt sulfur reduction zone. 2 figs.

Black-hole astrophysics  

SciTech Connect

Black-hole astrophysics is not just the investigation of yet another, even if extremely remarkable type of celestial body, but a test of the correctness of the understanding of the very properties of space and time in very strong gravitational fields. Physicists` excitement at this new prospect for testing theories of fundamental processes is matched by that of astronomers at the possibility to discover and study a new and dramatically different kind of astronomical object. Here the authors review the currently known ways that black holes can be identified by their effects on their neighborhood--since, of course, the hole itself does not yield any direct evidence of its existence or information about its properties. The two most important empirical considerations are determination of masses, or lower limits thereof, of unseen companions in binary star systems, and measurement of luminosity fluctuations on very short time scales.

Black Holes with Skyrme Hair  

E-Print Network (OSTI)

This paper is intended to give a review of the recent developments on black holes with Skyrme hair. The Einstein-Skyrme system is known to possess black hole solutions with Skyrme hair. The spherically symmetric black hole skyrmion with B=1 was the first discovered counter example of the no-hair conjecture for black holes. Recently we found the B=2 axially symmetric black hole skyrmion. In this system, the black hole at the center of the skyrmion absorbs the baryon number partially, leaving fractional charge outside the horizon. Therefore the baryon number is no longer conserved. We examine the B=1, 2 black hole solutions in detail in this paper. The model has a natural extension to the gauged version which can describe monopole black hole skyrmions. Callan and Witten discussed the monopole catalysis of proton decay within the Skyrme model. We apply the idea to the Einstein-Maxwell-Skyrme system and obtain monopole black hole skyrmions. Remarkably there exist multi-black hole skyrmion solutions in which the gravitational, electromagnetic, and strong forces between the monopoles are all in balance. The solutions turn out to be stable under spherically symmetric linear perturbations.

It has recently been shown that the M theory lift of a IIA 4D BPS Calabi-Yau black hole is a 5D BPS black hole spinning at the center of a Taub-NUT-flux geometries, and a certain linear relation between 4D and 5D BPS partition functions was accordingly proposed. In the present work we fortify and enrich this proposal by showing that the M-theory lift of the general 4D multi-black hole geometry are 5D black rings in a Taub-NUT-flux geometry.

It is found that the only option compatible with the preservation of the quantum unitarity is when a regular remnant region of the black hole survives to the black hole evaporation process, where information can be stored and eventually retrieved.

Black Strings, Black Rings and State-space Manifold  

E-Print Network (OSTI)

State-space geometry is considered, for diverse three and four parameter non-spherical horizon rotating black brane configurations, in string theory and $M$-theory. We have explicitly examined the case of unit Kaluza-Klein momentum $D_1D_5P$ black strings, circular strings, small black rings and black supertubes. An investigation of the state-space pair correlation functions shows that there exist two classes of brane statistical configurations, {\\it viz.}, the first category divulges a degenerate intrinsic equilibrium basis, while the second yields a non-degenerate, curved, intrinsic Riemannian geometry. Specifically, the solutions with finitely many branes expose that the two charged rotating $D_1D_5$ black strings and three charged rotating small black rings consort real degenerate state-space manifolds. Interestingly, arbitrary valued $M_5$-dipole charged rotating circular strings and Maldacena Strominger Witten black rings exhibit non-degenerate, positively curved, comprehensively regular state-space configurations. Furthermore, the state-space geometry of single bubbled rings admits a well-defined, positive definite, everywhere regular and curved intrinsic Riemannian manifold; except for the two finite values of conserved electric charge. We also discuss the implication and potential significance of this work for the physics of black holes in string theory.

Stars that are collapsing toward forming a black hole but are frozen near the Schwarzschild horizon are termed ``black stars''. Collisions of black stars, in contrast to black hole collisions, may be sources of gamma ray bursts, whose basic parameters are estimated quite simply and are found to be consistent with observed gamma ray bursts. Black star gamma ray bursts should be preceded by gravitational wave emission similar to that from the coalescence of black holes.

Black hole remnant of black hole-neutron star coalescing binaries with arbitrary black hole spin  

E-Print Network (OSTI)

A model for determining the dimensionless spin parameter and mass of the black hole remnant of black hole-neutron star mergers with arbitrary initial black hole spin angular momentum, binary mass ratio, and neutron star mass and cold equation of state is formulated. Tests against numerical-relativity results are carried out, showing that both the dimensionless spin parameter and the final mass are accurately reproduced. For the first time, the behaviour of both quantities and of the l = 2, m = 2, n = 0 quasinormal mode frequency is inspected throughout the parameter space. Predictions of this frequency may be exploited to guide gravitational wave modelling and detection efforts, and to extract physical information from detected gravitational wave signals that would help us break degeneracies between binary black hole and black hole-neutron star systems, improve our understanding of compact binary formation, and constrain the neutron star equation of state.

Black carbon snow albedo reduction Black carbon snow albedo reduction Title Black carbon snow albedo reduction Publication Type Journal Article Year of Publication 2012 Authors Hadley, Odelle L., and Thomas W. Kirchstetter Journal Nature Climate Change Volume 2 Pagination 437-440 Abstract Climate models indicate that the reduction of surface albedo caused by black-carbon contamination of snow contributes to global warming and near-worldwide melting of ice1, 2. In this study, we generated and characterized pure and black-carbon-laden snow in the laboratory and verified that black-carbon contamination appreciably reduces snow albedo at levels that have been found in natural settings1, 3, 4. Increasing the size of snow grains in our experiments decreased snow albedo and amplified the radiative perturbation of black carbon, which justifies the aging-related positive feedbacks that are included in climate models. Moreover, our data provide an extensive verification of the Snow, Ice and Aerosol Radiation model1, which will be included in the next assessment of the Intergovernmental Panel on Climate Change5.

Black Holes in Brane Worlds  

E-Print Network (OSTI)

In a Randall-Sundrum theory (RS1) 3+1 dimensional black holes and higher dimensional black holes are not the natural continuations of each other. 3+1 dimensional black holes decay into a large number of 4+1 dimensional black holes at a critical mass, Mcrit ? 10 32 TeV. Those black holes themselves may become unstable above another, albeit much smaller critical mass, M0 ? 10 3 TeV. Models of the universe with extra dimensions larger than the Planck length have been under intense investigation during the last few years [1, 2, 3, 4]. The general feature of these models is that standard model particles are compelled to live on 3-branes, to satisfy momentum conservation in 3+1 dimensions and to conform to other phenomenological bounds, while gravity pervades all dimensions. Many of these models predict the observation of black holes at future accelerators [1, 5, 6, 7]. The models either use flat but compact extra dimensions(ADD scenario) [1] or a number of branes embedded in AdS space, with warped extra dimension(s) [2, 3]. Black holes in theories with extra dimensions have been studied widely. The classic paper of Myers and Perry [8] found solutions in D-dimensional flat space. Black hole solutions were also found in AdS space [9, 10]. No non-trivial black hole solutions have been found in closed form in brane theories of the Randall Sundrum type. Yet, it is important to learn as much as possible about black holes in such models. The black string solution [11] that extends in a uniform manner from the brane into the extra dimension has the Gregory-Laflamme instability in the ADD scenario [11, 12]. It is easy to invoke an entropy argument [13], to show that an instability will occur at a critical mass. An alternative interpretation is given in [14]. To understand the arguments by Gregory and Laflamme, compare the entropies of standard 3+1 and 4+1 dimensional Schwarzschild black holes of the same mass. Then one obtains a critical mass

Of the Black Hole Thermodynamics

About thirty years ago, Bekenstein and Hawking introduced three basic concepts relating to black hole, namely, the "area entropy", "gravitation temperature" and "thermal radiation". The author analyzes these concepts systematically and concludes that they are mostly inadequate or wrong. He points out that a black hole's taking in thermal radiation from the space is an energy-gathering process. It is special, even extraordinary. It reduces entropy, violating Clausius' second law.

Are Black Holes Elementary Particles?  

E-Print Network (OSTI)

Quantum black holes are the smallest and heaviest conceivable elementary particles. They have a microscopic size but a macroscopic mass. Several fundamental types have been constructed with some remarkable properties. Quantum black holes in the neighborhood of the Galaxy could resolve the paradox of ultra-high energy cosmic rays detected in Earthís atmosphere. They may also play a role as dark matter in cosmology. 1 1

Regular black hole in three dimensions  

E-Print Network (OSTI)

We find a new black hole in three dimensional anti-de Sitter space by introducing an anisotropic perfect fluid inspired by the noncommutative black hole. This is a regular black hole with two horizons. We compare thermodynamics of this black hole with that of non-rotating BTZ black hole. The first-law of thermodynamics is not compatible with the Bekenstein-Hawking entropy.

Rotating Black Holes in Higher Dimensions  

E-Print Network (OSTI)

The properties of higher-dimensional black holes can differ significantly from those of black holes in four dimensions, since neither the uniqueness theorem, nor the staticity theorem or the topological censorship theorem generalize to higher dimensions. We first discuss black holes of Einstein-Maxwell theory and Einstein-Maxwell-Chern-Simons theory with spherical horizon topology. Here new types of stationary black holes are encountered. We then discuss nonuniform black strings and present evidence for a horizon topology changing transition.

Motivated by Maggiore's new interpretation of quasinormal modes, starting from the first law of thermodynamics of black holes, we investigate area spectra of a near extremal Schwarzschild de sitter black hole and a higher dimensional near extremal Reissner-Nordstrom de sitter black hole. Then we apply the method to the Kerr black hole. We show that the logarithmic term does not appear and the area spectra of all these black holes are equally spaced and irrelevant to the parameters of black holes.

Elm Elm Nature Bulletin No. 279-A October 21, 1967 Forest Preserve District of Cook County Richard B. Ogilvie, President Roland F. Eisenbeis, Supt. of Conservation THE AMERICAN ELM For three centuries, the stately graceful American Elm -- "the tree that like a fountain rises" -- has been our favorite shade tree, and around it have grown some of our finest traditions. The early colonists found huge patriarchs, which reminded them of the magnificent English Elms, and they planted seedlings to shade their homes and village commons. Today, innumerable New England roadways are lined with giant elms, their great arching limbs forming canopies like a cathedral roof. When the pioneers moved westward, they found this tree everywhere in the bottomlands and on low fertile hills. NOW, throughout the Middle West -- even in prosaic prairie towns -- streets and public buildings are shaded and given character by beautiful elms.

Kraft black liquor delivery systems  

DOE Green Energy (OSTI)

Improvement of spray nozzles for black liquor injection into kraft recovery furnaces is expected to result from obtaining a controlled, well-defined droplet size distribution. Work this year has centered on defining the capabilities of commercial black liquor nozzles currently in use. Considerations of the observed mechanism of droplet formation suggest a major revision is needed in the theory of how droplets form from these nozzles. High resolution, high sensitivity video has been shown to be superior to flash x-ray as a technique for measuring the droplet size distribution as well as the formation history. An environmentally sound spray facility capable of spraying black liquor at temperatures up to normal firing conditions is being constructed before data acquisition continues. Preliminary correlations have been developed between liquor properties, nozzle design, and droplet size. Three aspects of nozzle design have been investigated: droplet size distribution, fluid sheet thickness, and flow and pressure drop characteristics. The standard deviation about the median droplet size for black liquor is nearly the same as the for a wide variety of other fluids and nozzle types. Preliminary correlation for fluid sheet thickness on the plate of a splashplate nozzle show the strong similarities of black liquor to other fluids. The flow and pressure drop characteristic of black liquor nozzle, follow a simple two-term relationship similar to other flow devices. This means that in routine mill operation of black liquor nozzles only the fluid acceleration in the nozzle is important, viscous losses are quiet small. 21 refs., 53 figs., 10 tabs.

We describe the gravitational degrees of freedom of the Schwarzschild black hole by one free variable. We introduce an equation which we suggest to be the Schroedinger equation of the Schwarzschild black hole corresponding to this model. We solve the Schroedinger equation explicitly and obtain the mass spectrum of the black hole as such as it can be observed by an observer very far away and at rest relative to the black hole. Our equation implies that there is no singularity inside the Schwarzschild black hole, and that the black hole has a certain ground state in which its mass is non-zero.

Massive Black Holes: formation and evolution  

E-Print Network (OSTI)

Supermassive black holes are nowadays believed to reside in most local galaxies. Observations have revealed us vast information on the population of local and distant black holes, but the detailed physical properties of these dark massive objects are still to be proven. Accretion of gas and black hole mergers play a fundamental role in determining the two parameters defining a black hole: mass and spin. We briefly review here the basic properties of the population of supermassive black holes, focusing on the still mysterious formation of the first massive black holes, and their evolution from early times to now.

There is a remarkable analogy between the hydrodynamics of such systems and the quantum theory of black holes. I will show how insights from this analogy have shed light on recent experiments on the cuprate high temperature superconductors. Studies of new materials and trapped ultracold atoms are yielding new quantum phases, with novel forms of quantum entanglement. Some materials are of technological importance: e.g. high temperature superconductors. Exact solutions via black hole mapping have yielded first exact results for transport coefficients in interacting many-body systems, and were valuable in determining general structure of hydrodynamics.

Enhanced Black Hole Horizon Fluctuations  

E-Print Network (OSTI)

We discuss the possible role of quantum horizon fluctuations on black hole radiance, especially whether they can invalidate Hawking's analysis based upon transplanckian modes. We are particularly concerned with ``enhanced'' fluctuations produced by gravitons or matter fields in squeezed vacuum states sent into the black hole after the collapse process. This allows for the possibility of increasing the fluctuations well above the vacuum level. We find that these enhanced fluctuations could significantly alter stimulated emission but have little effect upon the spontaneous emission. Thus the thermal character of the Hawking radiation is remarkably robust.

Information Loss in Black Holes  

E-Print Network (OSTI)

The question of whether information is lost in black holes is investigated using Euclidean path integrals. The formation and evaporation of black holes is regarded as a scattering problem with all measurements being made at infinity. This seems to be well formulated only in asymptotically AdS spacetimes. The path integral over metrics with trivial topology is unitary and information preserving. On the other hand, the path integral over metrics with non-trivial topologies leads to correlation functions that decay to zero. Thus at late times only the unitary information preserving path integrals over trivial topologies will contribute. Elementary quantum gravity interactions do not lose information or quantum coherence.

In fluid and solid systems, the sign of $R$ indicates the character of microscopic interactions, repulsive or attractive. $|R|$ gives the average size of organized mesoscopic fluctuating structures. The broad generality of thermodynamic principles might lead one to believe the same for black hole thermodynamics.

4d neutral dilatonic black holes and (4+p) dimensional nondilatonic black p-branes  

E-Print Network (OSTI)

It is shown that, in contrast to the case of extreme 4d dilatonic black holes, 4d neutral dilatonic black holes with horizon singularities can not be interpreted as nonsingular nondilatonic black p-branes in (4+p) dimensions, regardless of the number of extra dimensions p. That is, extra dimensions do not remove naked singularities of 4d neutral dilatonic black holes.

Black Hole Spectrum: Continuous or Discrete?

We formulate a qualitative argument, based on Heisenberg's uncertainty principle, to support the claim that when the effects of matter fields are assumed to overshadow the effects of quantum mechanics of spacetime, the discrete spectrum of black hole radiation, as such as predicted by Bekenstein's proposal for a discrete black hole area spectrum, reduces to Hawking's black-body spectrum.

FORCE-FEEDING BLACK HOLES  

SciTech Connect

We propose that the growth of supermassive black holes is associated mainly with brief episodes of highly super-Eddington infall of gas ({sup h}yperaccretion{sup )}. This gas is not swallowed in real time, but forms an envelope of matter around the black hole that can be swallowed gradually, over a much longer timescale. However, only a small fraction of the black hole mass can be stored in the envelope at any one time. We argue that any infalling matter above a few percent of the hole's mass is ejected as a result of the plunge in opacity at temperatures below a few thousand degrees kelvin, corresponding to the Hayashi track. The speed of ejection of this matter, compared to the velocity dispersion {sigma} of the host galaxy's core, determines whether the ejected matter is lost forever or returns eventually to rejoin the envelope, from which it can be ultimately accreted. The threshold between matter recycling and permanent loss defines a relationship between the maximum black hole mass and {sigma} that resembles the empirical M{sub BH}-{sigma} relation.

Black Hole fragmentation and holography  

E-Print Network (OSTI)

We discuss the entropy change due to fragmentation for black hole solutions in various dimensions. We find three different types of behavior. The entropy may decrease, increase or have a mixed behavior, characterized by the presence of a threshold mass. For two-dimensional (2D) black holes we give a complete characterization of the entropy behavior under fragmentation, in the form of sufficient conditions imposed on the function J, which defines the 2D gravitational model. We compare the behavior of the gravitational solutions with that of free field theories in d dimensions. This excludes the possibility of finding a gravity/field theory realization of the holographic principle for a broad class of solutions, including asymptotically flat black holes. We find that the most natural candidates for holographic duals of the black hole solutions with mixed behavior are field theories with a mass gap. We also discuss the possibility of formulating entropy bounds that make reference only to the energy of a system.

Rotating Black Holes with Monopole Hair  

E-Print Network (OSTI)

We study rotating black holes in Einstein-Yang-Mills-Higgs theory. These black holes emerge from static black holes with monopole hair when a finite horizon angular velocity is imposed. At critical values of the horizon angular velocity and the horizon radius, they bifurcate with embedded Kerr-Newman black holes. The non-Abelian black holes possess an electric dipole moment, but no electric charge is induced by the rotation. We deduce that gravitating regular monopoles possess a gyroelectric ratio g_el=2.

Black Hole Radiation and Volume Statistical Entropy  

E-Print Network (OSTI)

The simplest possible equation for Hawking radiation, and other black hole radiated power is derived in terms of black hole density. Black hole density also leads to the simplest possible model of a gas of elementary constituents confined inside a gravitational bottle of Schwarzchild radius at tremendous pressure, which yields identically the same functional dependence as the traditional black hole entropy. Variations of Sbh can be obtained which depend on the occupancy of phase space cells. A relation is derived between the constituent momenta and the black hole radius which is similar to the Compton wavelength relation.

Black holes: from stars to galaxies  

E-Print Network (OSTI)

While until recently they were often considered as exotic objects of dubious existence, in the last decades there have been overwhelming observational evidences for the presence of stellar mass black holes in binary systems, supermassive black holes at the centers of galaxies, and possibly, intermediate-mass black holes observed as ultraluminous X-ray sources in nearby galaxies. Black holes are now widely accepted as real physical entities that play an important role in several areas of modern astrophysics. Here I review the concluding remarks of the IAU Sympposium No 238 on Black Holes, with particular emphasis on the topical questions in this area of research.

Black Hole Evaporation as a Nonequilibrium Process  

E-Print Network (OSTI)

When a black hole evaporates, there arises a net energy flow from the black hole into its outside environment due to the Hawking radiation and the energy accretion onto black hole. Exactly speaking, due to the net energy flow, the black hole evaporation is a nonequilibrium process. To study details of evaporation process, nonequilibrium effects of the net energy flow should be taken into account. In this article we simplify the situation so that the Hawking radiation consists of non-self-interacting massless matter fields and also the energy accretion onto the black hole consists of the same fields. Then we find that the nonequilibrium nature of black hole evaporation is described by a nonequilibrium state of that field, and we formulate nonequilibrium thermodynamics of non-self-interacting massless fields. By applying it to black hole evaporation, followings are shown: (1) Nonequilibrium effects of the energy flow tends to accelerate the black hole evaporation, and, consequently, a specific nonequilibrium phenomenon of semi-classical black hole evaporation is suggested. Furthermore a suggestion about the end state of quantum size black hole evaporation is proposed in the context of information loss paradox. (2) Negative heat capacity of black hole is the physical essence of the generalized second law of black hole thermodynamics, and self-entropy production inside the matter around black hole is not necessary to ensure the generalized second law. Furthermore a lower bound for total entropy at the end of black hole evaporation is given. A relation of the lower bound with the so-called covariant entropy bound conjecture is interesting but left as an open issue.

Accelerating and rotating black holes

An exact solution of Einstein's equations which represents a pair of accelerating and rotating black holes (a generalised form of the spinning C-metric) is presented. The starting point is a form of the Plebanski-Demianski metric which, in addition to the usual parameters, explicitly includes parameters which describe the acceleration and angular velocity of the sources. This is transformed to a form which explicitly contains the known special cases for either rotating or accelerating black holes. Electromagnetic charges and a NUT parameter are included, the relation between the NUT parameter $l$ and the Plebanski-Demianski parameter $n$ is given, and the physical meaning of all parameters is clarified. The possibility of finding an accelerating NUT solution is also discussed.

Finally, we discuss the slowly rotating case for arbitrary dilaton coupling.

This test program was based on the evaluation of four unique solar collectors described as follows: (a) black nickel collector surface with a desiccant drying bed, (b) black nickel collector surface without a desiccant drying bed, (c) black chrome collector surface with a dessicant drying bed, and (d) black chrome collector surface without a desiccant drying bed. The test program included three distinct phases: Initial performance evaluation, natural environmental aging, and post-aging performance evaluation. Results of Phase III testing conclusively indicated a higher normalized efficiency for black chrome surfaces when compared to black nickel. Analysis of these results is shown. The results are tabulated.

Great American Smokeout ó  

E-Print Network (OSTI)

by the American Cancer Society, is an annual event that encourages smokers to quit for at least 1 day in the hope that this might challenge them to stop permanently (1). This year, GASO will be held on November 18. Major changes have occurred since the first GASO in 1977. In 1978, approximately 34 % of adults smoked; by 2009, nearly 21 % smoked (2Ė4). Federal laws now prohibit smoking on airlines, and 24 states and the District of Columbia have comprehensive smoking bans (3,4). The U.S. government also has added coverage of smoking cessation treatments to health plans. As of October 1, 2010, Medicaid programs are required to cover tobaccodependence treatments for pregnant women, and in 2011, cessation coverage will be provided to all federal employees, retirees, and their spouses and dependents. Despite progress, 46.6 million U.S. adults smoke, 40% of nonsmokers are exposed to secondhand smoke, and 443,000 deaths each year are attributed to smoking and secondhand smoke (3Ė5). Additional information and support for quitting is available online

North American EV show  

Science Conference Proceedings (OSTI)

The hit of the North American EV and Infrastructure Conference held in Phoenix, AZ in December, was without a doubt, the new hybrid vehicle from Toyota known as the Prius. The Prius has both an internal combustion engine and an electric motor. As ordinary as it may appear, there`s a critical difference between the Prius and the other electric vehicles that were being demonstrated in Phoenix. Prius is an electric vehicle that never needs to be recharged. Range is not an issue, nor is battery replacement. This is the first mass-produced car with hybrid power providing the benefits of low emissions and high gasoline mileage in a real-world vehicle that can be driven anywhere. Many other alternative fueled vehicles were on display from other manufacturers as well. GM`s EV1, Nissan`s Altra station wagon, Ford`s electric Ranger pickup, DaimlerChrysler`s EPIC van as well as small, short-range ``neighborhood vehicles`` from Bombardier and Global Electric Motor-Cars were available for inspection and test drives.

Combustion properties of Kraft Black Liquors  

DOE Green Energy (OSTI)

In a previous study of the phenomena involved in the combustion of black liquor droplets a numerical model was developed. The model required certain black liquor specific combustion information which was then not currently available, and additional data were needed for evaluating the model. The overall objectives of the project reported here was to provide experimental data on key aspects of black liquor combustion, to interpret the data, and to put it into a form which would be useful for computational models for recovery boilers. The specific topics to be investigated were the volatiles and char carbon yields from pyrolysis of single black liquor droplets; a criterion for the onset of devolatilization and the accompanying rapid swelling; and the surface temperature of black liquor droplets during pyrolysis, combustion, and gasification. Additional information on the swelling characteristics of black liquor droplets was also obtained as part of the experiments conducted.

Modeling Flows Around Merging Black Hole Binaries  

E-Print Network (OSTI)

Coalescing massive black hole binaries are produced by the mergers of galaxies. The final stages of the black hole coalescence produce strong gravitational radiation that can be detected by the space-borne LISA. In cases where the black hole merger takes place in the presence of gas and magnetic fields, various types of electromagnetic signals may also be produced. Modeling such electromagnetic counterparts of the final merger requires evolving the behavior of both gas and fields in the strong-field regions around the black holes. We have taken a step towards solving this problem by mapping the flow of pressureless matter in the dynamic, 3-D general relativistic spacetime around the merging black holes. We find qualitative differences in collision and outflow speeds, including a signature of the merger when the net angular momentum of the matter is low, between the results from single and binary black holes, and between nonrotating and rotating holes in binaries. If future magnetohydrodynamic results confirm ...

Geothermal energy for American Samoa  

SciTech Connect

The geothermal commercialization potential in American Samoa was investigated. With geothermal energy harnessed in American Samoa, a myriad of possibilities would arise. Existing residential and business consumers would benefit from reduced electricity costs. The tuna canneries, demanding about 76% of the island's process heat requirements, may be able to use process heat from a geothermal source. Potential new industries include health spas, aquaculture, wood products, large domestic and transhipment refrigerated warehouses, electric cars, ocean nodule processing, and a hydrogen economy. There are no territorial statutory laws of American Samoa claiming or reserving any special rights (including mineral rights) to the territorial government, or other interests adverse to a land owner, for subsurface content of real property. Technically, an investigation has revealed that American Samoa does possess a geological environment conducive to geothermal energy development. Further studies and test holes are warranted.

Magnetized black holes and black rings in the higher dimensional dilaton gravity  

E-Print Network (OSTI)

In this paper we consider magnetized black holes and black rings in the higher dimensional dilaton gravity. Our study is based on exact solutions generated by applying a Harrison transformation to known asymptotically flat black hole and black ring solutions in higher dimensional spacetimes. The explicit solutions include the magnetized version of the higher dimensional Schwarzschild-Tangherlini black holes, Myers-Perry black holes and five dimensional (dipole) black rings. The basic physical quantities of the magnetized objects are calculated. We also discuss some properties of the solutions and their thermodynamics. The ultrarelativistic limits of the magnetized solutions are briefly discussed and an explicit example is given for the $D$-dimensional magnetized Schwarzschild-Tangherlini black holes.

Black Hole Information as Topological Qubits

The principle of balanced holography, introduced in [1], posits that black hole information is stored in non-local correlations between the interior and exterior. Based on this concept, we propose that black hole information decomposes into elementary units in the form of topological qubits, and is protected from local sources of decoherence. The topological protection mechanism ensures that the horizon of an evaporating black hole stays young and smooth.

Rotating Einstein-Yang-Mills Black Holes  

E-Print Network (OSTI)

We construct rotating hairy black holes in SU(2) Einstein-Yang-Mills theory. These stationary axially symmetric black holes are asymptotically flat. They possess non-trivial non-Abelian gauge fields outside their regular event horizon, and they carry non-Abelian electric charge. In the limit of vanishing angular momentum, they emerge from the neutral static spherically symmetric Einstein-Yang-Mills black holes, labelled by the node number of the gauge field function. With increasing angular momentum and mass, the non-Abelian electric charge of the solutions increases, but remains finite. The asymptotic expansion for these black hole solutions includes non-integer powers of the radial variable.

Strings, black holes, and quantum information  

SciTech Connect

We find multiple relations between extremal black holes in string theory and 2- and 3-qubit systems in quantum information theory. We show that the entropy of the axion-dilaton extremal black hole is related to the concurrence of a 2-qubit state, whereas the entropy of the STU black holes, Bogomol'nyi-Prasad-Sommerfield (BPS) as well as non-BPS, is related to the 3-tangle of a 3-qubit state. We relate the 3-qubit states with the string theory states with some number of D-branes. We identify a set of large black holes with the maximally entangled Greenberger, Horne, Zeilinger (GHZ) class of states and small black holes with separable, bipartite, and W states. We sort out the relation between 3-qubit states, twistors, octonions, and black holes. We give a simple expression for the entropy and the area of stretched horizon of small black holes in terms of a norm and 2-tangles of a 3-qubit system. Finally, we show that the most general expression for the black hole and black ring entropy in N=8 supergravity/M theory, which is given by the famous quartic Cartan E{sub 7(7)} invariant, can be reduced to Cayley's hyperdeterminant describing the 3-tangle of a 3-qubit state.

Superconducting Hair on Charged Black String Background  

E-Print Network (OSTI)

Behaviour of Dirac fermions in the background of a charged black string penetrated by an Abelian Higgs vortex is elaborated. One finds the evidence that the system under consideration can support fermion fields acting like a superconducting cosmic string in the sence that a nontrivial Dirac fermion field can be carried by the system in question. The case of nonextremal and extremal black string vortex systems were considered. The influence of electric and Higgs charge, the winding number and the fermion mass on the fermion localization near the black string event horizon was studied. It turned out that the extreme charged black string expelled fermion fields more violently comparing to the nonextremal one.

Quantum Black Holes As Elementary Particles

Are black holes elementary particles? Are they fermions or bosons? We investigate the remarkable possibility that quantum black holes are the smallest and heaviest elementary particles. We are able to construct various fundamental quantum black holes: the spin-0, spin-1/2, spin-1, and the Planckcharge cases, using the results in general relativity. Quantum black holes in the neighborhood of the Galaxy could resolve the paradox posed by the Greisen-Zatsepin-Kuzmin limit on the energy of cosmic rays from distant sources. They could also play a role as dark matter in cosmology.

Causticizing for Black Liquor Gasifiers  

SciTech Connect

The cost-benefit outlook of black liquor gasification (BLG) could be greatly improved if the smelt causticization step could be achieved in situ during the gasification step. Or, at a minimum, the increase in causticizing load associated with BLG could be mitigated. A number of chemistries have been proven successful during black liquor combustion. In this project, three in situ causticizing processes (titanate, manganate, and borate) were evaluated under conditions suitable for high temperature entrained flow BLG, and low temperature steam reforming of black liquor. The evaluation included both thermodynamic modeling and lab experimentation. Titanate and manganate were tested for complete direct causticizing (to thus eliminate the lime cycle), and borates were evaluated for partial causticizing (to mitigate the load increase associated with BLG). Criteria included high carbonate conversion, corresponding hydroxide recovery upon hydrolysis, non process element (NPE) removal, and economics. Of the six cases (three chemistries at two BLG conditions), only two were found to be industrially viable: titanates for complete causticizing during high temperature BLG, and borates for partial causticizing during high temperature BLG. These two cases were evaluated for integration into a gasification-based recovery island. The Larsen [28] BLG cost-benefit study was used as a reference case for economic forecasting (i.e. a 1500 tpd pulp mill using BLG and upgrading the lime cycle). By comparison, using the titanate direct causticizing process yielded a net present value (NPV) of $25M over the NPV of BLG with conventional lime cycle. Using the existing lime cycle plus borate autocausticizing for extra capacity yielded a NPV of $16M.

Black hole discharge in massive electrodynamics and black hole disappearance in massive gravity

We define and calculate the "discharge mode" for a Schwarzschild black hole in massive electrodynamics. For small photon mass, the discharge mode describes the decay of the electric field of a charged star collapsing into a black hole. We argue that a similar "discharge of mass" occurs in massive gravity and leads to a strange process of black hole disappearance.

African sedimentary basins - Tectonic controls on prospectivity  

Science Conference Proceedings (OSTI)

An important prerequisite for the evaluation of any sedimentary basin is the understanding of its regional tectonic setting. This is especially so in the underexplored regions of Africa. The majority of African sedimentary basins developed in an extensional setting although some have undergone subsequent compressional or transpressional deformation. The geometry and evolution of these basins is often influenced by basement structure. The extensional phase of basin development controls not only the distribution of syn-rift sediments but also the magnitude of post-rift regional subsidence and the preservation or removal of pre-rift sediments. This has important consequences for exploration models of syn-rift and pre-rift source rocks and reservoirs. Post-rift basin inversion and uplift provide crucial controls on the preservation of mature source rocks and quality of reservoirs. The distribution, nature, timing, and possible mechanisms of this uplift in Africa will be addressed. The hydrocarbon prospectivity of African basis appears to be highly variable although the limited exploration of some regions makes the exact extent of this variability unclear. Basins considered potentially prospective range from late Precambrian to Tertiary in age. The various tectonic controls outlined above, and criteria for the evaluation of underexplored areas, will be demonstrated by reference to basins studied by The Robertson Group. Examples described include basins from Bagon, Angola, Namibia, East Africa, Tertiary Rift and Karoo Rifts, and North Africa (Sudan, Egypt, Algeria, and Morocco).

Primordial Black Holes - Recent Developments  

E-Print Network (OSTI)

Recent developments in the study of primordial black holes (PBHs) will be reviewed, with particular emphasis on their formation and evaporation. PBHs could provide a unique probe of the early Universe, gravitational collapse, high energy physics and quantum gravity. Indeed their study may place interesting constraints on the physics relevant to these areas even if they never formed. In the "early Universe" context, particularly useful constraints can be placed on inflationary scenarios, especially if evaporating PBHs leave stable Planck-mass relicts. In the "gravitational collapse" context, the existence of PBHs could provide a unique test of the sort of critical phenomena discovered in recent numerical calculations. In the "high energy physics" context, information may come from gamma-ray bursts (if a subset of these are generated by PBH explosions) or from cosmic rays (if some of these derive from evaporating PBHs). In the "quantum gravity" context, the formation and evaporation of small black holes could lead to observable signatures in cosmic ray events and accelerator experiments, providing there are extra dimensions and providing the quantum gravity scale is around a TeV.

Refractory for Black Liquor Gasifiers  

SciTech Connect

The University of Missouri-Rolla will identify materials that will permit the safe, reliable and economical operation of combined cycle gasifiers by the pulp and paper industry. The primary emphasis of this project will be to resolve the materials problems encountered during the operation of low-pressure high-temperature (LFHT) and low-pressure low-temperature (LPLT) gasifiers while simultaneously understanding the materials barriers to the successful demonstration of high-pressure high-temperature (HPHT) black liquor gasifiers. This study will define the chemical, thermal and physical conditions in current and proposed gasifier designs and then modify existing materials and develop new materials to successfully meet the formidable material challenges. Resolving the material challenges of black liquor gasification combined cycle technology will provide energy, environmental, and economic benefits that include higher thermal efficiencies, up to three times greater electrical output per unit of fuel, and lower emissions. In the near term, adoption of this technology will allow the pulp and paper industry greater capital effectiveness and flexibility, as gasifiers are added to increase mill capacity. In the long term, combined-cycle gasification will lessen the industry's environmental impact while increasing its potential for energy production, allowing the production of all the mill's heat and power needs along with surplus electricity being returned to the grid. An added benefit will be the potential elimination of the possibility of smelt-water explosions, which constitute an important safety concern wherever conventional Tomlinson recovery boilers are operated. Developing cost-effective materials with improved performance in gasifier environments may be the best answer to the material challenges presented by black liquor gasification. Refractory materials may be selected/developed that either react with the gasifier environment to form protective surfaces in-situ; are functionally-graded to give the best combination of thermal, mechanical, and physical properties and chemical stability; or are relatively inexpensive, reliable repair materials. Material development will be divided into 2 tasks: Task 1, Development and property determinations of improved and existing refractory systems for black liquor containment. Refractory systems of interest include magnesia aluminate and baria aluminate spinels for binder materials, both dry and hydratable, and materials with high alumina contents, 85-95 wt%, aluminum oxide, 5.0-15.0 wt%, and BaO, SrO, CaO, ZrO and SiC. Task 2, Finite element analysis of heat flow and thermal stress/strain in the refractory lining and steel shell of existing and proposed vessel designs. Stress and strain due to thermal and chemical expansion has been observed to be detrimental to the lifespan of existing black liquor gasifiers. The thermal and chemical strain as well as corrosion rates must be accounted for in order to predict the lifetime of the gasifier containment materials.

Refractory for Black Liquor Gasifiers  

SciTech Connect

The University of Missouri-Rolla identified materials that permit the safe, reliable and economical operation of combined cycle gasifiers by the pulp and paper industry. The primary emphasis of this project was to resolve the material problems encountered during the operation of low-pressure high-temperature (LPHT) and low-pressure low-temperature (LPLT) gasifiers while simultaneously understanding the materials barriers to the successful demonstration of high-pressure high-temperature (HPHT) black liquor gasifiers. This study attempted to define the chemical, thermal and physical conditions in current and proposed gasifier designs and then modify existing materials and develop new materials to successfully meet the formidable material challenges. Resolving the material challenges of black liquor gasification combined cycle technology will provide energy, environmental, and economic benefits that include higher thermal efficiencies, up to three times greater electrical output per unit of fuel, and lower emissions. In the near term, adoption of this technology will allow the pulp and paper industry greater capital effectiveness and flexibility, as gasifiers are added to increase mill capacity. In the long term, combined-cycle gasification will lessen the industry's environmental impact while increasing its potential for energy production, allowing the production of all the mill's heat and power needs along with surplus electricity being returned to the grid. An added benefit will be the potential elimination of the possibility of smelt-water explosions, which constitute an important safety concern wherever conventional Tomlinson recovery boilers are operated. Developing cost-effective materials with improved performance in gasifier environments may be the best answer to the material challenges presented by black liquor gasification. Refractory materials were selected/developed that either react with the gasifier environment to form protective surfaces in-situ; and were functionally-graded to give the best combination of thermal, mechanical, and physical properties and chemical stability; or are relatively inexpensive, reliable repair materials. Material development were divided into 2 tasks: Task 1, Development and property determinations of improved and existing refractory systems for black liquor containment. Refractory systems of interest include magnesium aluminate and barium aluminate for binder materials, both dry and hydratable, and materials with high alumina contents, 85-95 wt%, aluminum oxide, 5.0-15.0 wt%, and BaO, SrO, CaO, ZrO{sub 2} and SiC. Task 2, Finite element analysis of heat flow and thermal stress/strain in the refractory lining and steel shell of existing and proposed vessel designs. Stress and strain due to thermal and chemical expansion has been observed to be detrimental to the lifespan of existing black liquor gasifiers. The thermal and chemical strain as well as corrosion rates must be accounted for in order to predict the lifetime of the gasifier containment materials.

A study of the social organization of contemorary American rodeo  

E-Print Network (OSTI)

American rodeo has undergone a dramatic metamorphosis over the past century, as it evolved from a small-time attraction in rural Western communities into a large-scale social and economic institution. One result of this evolution has been the formation of functionally specialized types of rodeo. Using the epigenetic theoretical perspective as an analytical tool, this study examines the "initiation" and "take-off' of twelve types of contemporary rodeo (i.e., professional, women's, collegiate, high school, youth, senior, gay, military, black, Indian, prison, and ranch) into self-sustained institutions. It identifies and describes the organizational characteristics of the different types of rodeo, and identifies, describes, and assesses the various functions and possible dysfunctions rodeo serves.

This report covers Task 1.4, Industrial Trial of candidate materials developed by refractory producers and in the laboratory based on the results of Task 1.1, 1.2 and 1.3. Refractories provided by in-kind sponsors to industrial installations tested by cup testing, density/porosity determinations, chemical analysis and microscopy. None of the materials produced in this program have been tried in high temperature gasifiers, but the mortar developed Morcocoat SP-P is outperforming other mortars tested at ORNL. MORCO PhosGun M-90-O has shown in laboratory testing to be an acceptable candidate for hot and cold repairs of existing high temperature gasifiers. It may prove to be an acceptable lining material.

The fuzzball proposal for black holes  

E-Print Network (OSTI)

The fuzzball proposal states that associated with a black hole of entropy S there are exp S horizon-free non-singular solutions that asymptotically look like the black hole but generically differ from the black hole up to the horizon scale. These solutions, the fuzzballs, are considered to be the black hole microstates while the original black hole represents the average description of the system. The purpose of this report is to review current evidence for the fuzzball proposal, emphasizing the use of AdS/CFT methods in developing and testing the proposal. In particular, we discuss the status of the proposal for 2 and 3 charge black holes in the D1-D5 system, presenting new derivations and streamlining the discussion of their properties. Results to date support the fuzzball proposal but further progress is likely to require going beyond the supergravity approximation and sharpening the definition of a "stringy fuzzball". We outline how the fuzzball proposal could resolve longstanding issues in black hole physics, such as Hawking radiation and information loss. Our emphasis throughout is on connecting different developments and identifying open problems and directions for future research.

We study Einstein gravity minimally coupled to a scalar field in a static, spherically symmetric space-time in four dimensions. Black hole solutions are shown to exist for a phantom scalar field whose kinetic energy is negative. These ``scalar black holes'' have an infinite horizon area and zero Hawking temperature and are termed ``cold black holes'' (CBHs). The relevant explicit solutions are well-known in the massless case (the so-called anti-Fisher solution), and we have found a particular example of a CBH with a nonzero potential $V(\\phi)$.

Black Hole Thermodynamics and Statistical Mechanics  

E-Print Network (OSTI)

We have known for more than thirty years that black holes behave as thermodynamic systems, radiating as black bodies with characteristic temperatures and entropies. This behavior is not only interesting in its own right; it could also, through a statistical mechanical description, cast light on some of the deep problems of quantizing gravity. In these lectures, I review what we currently know about black hole thermodynamics and statistical mechanics, suggest a rather speculative "universal" characterization of the underlying states, and describe some key open questions.

Some aspects of virtual black holes  

SciTech Connect

We first consider consistently third-quantize modified gravity. We then analyze certain aspects of virtual black holes in this third-quantized modified gravity. We see how a statistical mechanical origin for the Bekenstein-Hawking entropy naturally arises in this model. Furthermore, the area and hence the entropy of a real macroscopic black hole is quantized in this model. Virtual black holes cause a loss of quantum coherence, which gives an intrinsic entropy to all physical systems that can be used to define a direction of time and hence provide a solution to the problem of time.

Thermodynamics of Dyonic Lifshitz Black Holes  

E-Print Network (OSTI)

Black holes with asymptotic anisotropic scaling are conjectured to be gravity duals of condensed matter system close to quantum critical points with non-trivial dynamical exponent z at finite temperature. A holographic renormalization procedure is presented that allows thermodynamic potentials to be defined for objects with both electric and magnetic charge in such a way that standard thermodynamic relations hold. Black holes in asymptotic Lifshitz spacetimes can exhibit paramagnetic behavior at low temperature limit for certain values of the critical exponent z, whereas the behavior of AdS black holes is always diamagnetic.

Some remarks on black hole thermodynamics  

E-Print Network (OSTI)

Two thermodynamic "paradoxes" of black hole physics are re-examined. The first is that there is a thermal instability involving two coupled blackbody cavities containing two black holes, and second is that a classical black hole can swallow up entropy in the form of ambient blackbody photons without increasing its mass. The resolution of the second paradox by Bekenstein and by Hawking is re-visited. The link between Hawking radiation and Wigner's superluminal tunneling time is discussed using two equivalent Feynman diagrams, and Feynman's re-interpretation principle.

What Black Holes Can Teach Us  

E-Print Network (OSTI)

Black holes merge together different field of physics. From General Relativity over thermodynamics and quantum field theory, they do now also reach into the regime of particle and collider physics. In the presence of additional compactified dimensions, it would be possible to produce tiny black holes at future colliders. We would be able to test Planck scale physics and the onset of quantum gravity. The understanding of black hole physics is a key knowledge to the phenomenology of these new effects beyond the Standard Model. This article gives a brief introduction into the main issues and is addressed to a non-expert audience.

Might Dark Matter be Actually Black?  

DOE Green Energy (OSTI)

There have been proposals that primordial black hole remnants (BHRs) are the dark matter, but the idea is somewhat vague. We argue here first that the generalized uncertainty principle (GUP) may prevent black holes from evaporating completely, in a similar way that the standard uncertainty principle prevents the hydrogen atom from collapsing. Secondly we note that the hybrid inflation model provides a plausible mechanism for production of large numbers of small black holes. Combining these we suggest that the dark matter might be composed of Planck-size BHRs and discuss the possible constraints and signatures associated with this notion.

E-Print Network (OSTI)

We study thermodynamics of the Schwarzschild-de Sitter black hole in five dimensions by introducing two temperatures based on the standard and Bousso-Hawking normalizations. We use the first-law of thermodynamics to derive thermodynamic quantities. The two temperatures indicate that the Nariai black hole is thermodynamically unstable. However, it seems that black hole thermodynamics favors the standard normalization, and does not favor the Bousso-Hawking normalization.

Supersymmetric 4D Rotating Black Holes from 5D Black Rings  

E-Print Network (OSTI)

We present supersymmetric solutions describing black holes with non-vanishing angular momentum in four dimensional asymptotically flat space. The solutions are obtained by Kaluza-Klein reduction of five-dimensional supersymmetric black rings wrapped on the fiber of a Taub-NUT space. We show that in the four-dimensional description the singularity of the nut can be hidden behind a regular black hole event horizon and thereby obtain an explicit example of a non-static multi-black hole solution in asymptotically flat four dimensions.

Cleanup of plutonium oxide reduction black salts  

Science Conference Proceedings (OSTI)

This work describes pyrochemical processes employed to convert direc oxide reduction (DOR) black salts into discardable white salt and plutonium metal. The DOR process utilizes calcium metal as the reductant in a molten calcium chloride solvent salt to convert plutonium oxide to plutonium metal. An insoluble plutonium-rich dispersion called black salt sometimes forms between the metal phase and the salt phase. Black salts accumulated for processing were treated by one of two methods. One method utilized a scrub alloy of 70 wt % magnesium/30 wt % zinc. The other method utilized a pool of plutonium metal to agglomerate the metal phase. The two processes were similar in that calcium metal reductant and calcium chloride solvent salt were used in both cases. Four runs were performed by each method, and each method produced greater than 93% conversion of the black salt.

Charged fermions tunneling from regular black holes  

SciTech Connect

We study Hawking radiation of charged fermions as a tunneling process from charged regular black holes, i.e., the Bardeen and ABGB black holes. For this purpose, we apply the semiclassical WKB approximation to the general covariant Dirac equation for charged particles and evaluate the tunneling probabilities. We recover the Hawking temperature corresponding to these charged regular black holes. Further, we consider the back-reaction effects of the emitted spin particles from black holes and calculate their corresponding quantum corrections to the radiation spectrum. We find that this radiation spectrum is not purely thermal due to the energy and charge conservation but has some corrections. In the absence of charge, e = 0, our results are consistent with those already present in the literature.

Assessment of black liquor recovery boilers  

DOE Green Energy (OSTI)

In the paper making industry, pulpwood chips are digested and cooked to provide the pulp going to the refining and paper mills. Black liquor residue, containing the dissolved lignin binder from the chips, with a concentration of 12 to 16% solids, is further concentrated to 62 to 65% solids and mixed with salt cake, Sodium Sulfate (Na/sub 2/SO/sub 4/). The resulting concentrate of black liquor serves both as a fuel for generating steam in the boiler and also as the mother liquid from which other process liquors are recovered and recycled. Because the black liquor fuel contains high alkali concentrations, 18.3% sodium, 3.6% sulfur, an amount typical of midwestern bituminous coal, and measurable amounts of silica, iron oxides and other species, the black liquor boiler experience was reviewed for application to MHD boiler technology.

How to interpret black hole entropy?  

E-Print Network (OSTI)

We consider a possibility that the entropy of a Schwarzschild black hole has two different interpretations: The black hole entropy can be understood either as an outcome of a huge degeneracy in the mass eigenstates of the hole, or as a consequence of the fact that the interior region of black hole spacetime is separated from the exterior region by a horizon. In the latter case, no degeneracy in the mass eigenstates needs to be assumed. Our investigation is based on calculations performed with Lorentzian partition functions obtained for a whole maximally extended Schwarzschild spacetime, and for its right-hand-side exterior region. To check the correctness of our analysis we reproduce, in the leading order approximation, the Bekenstein--Hawking entropy of the Schwarzschild black hole.

We compute the free energy of a charged black hole from the holographic dual, a 2d CFT with extended conformal symmetry, and find exact agreement with the bulk thermodynamics. In the CFT, higher spin corrections to the free energy can be calculated at high temperature from correlation functions of W-algebra currents.

Parikh-Wilczek tunnelling framework is investigated again. We argue that Parikh-Wilczek's treatment, which satisfies the first law of black hole thermodynamics and consists with an underlying unitary theory, is only suitable for a reversible process. Because of the negative heat capacity, an evaporating black hole is a highly unstable system. That is, the factual emission process is irreversible, the unitary theory will not be satisfied and the information loss is possible.

Iron mobilization in North African dust.  

SciTech Connect

Iron is an essential nutrient for phytoplankton. Although iron-containing dust mobilized from arid regions supplies the majority of the iron to the oceans, the key flux in terms of the biogeochemical response to atmospheric deposition is the amount of soluble or bioavailable iron. Atmospheric processing of mineral aerosols by anthropogenic pollutants (e.g. sulfuric acid) may transform insoluble iron into soluble forms. Previous studies have suggested higher iron solubility in smaller particles, as they are subject to more thorough atmospheric processing due to a longer residence time than coarse particles. On the other hand, the specific mineralogy of iron in dust may also influence the particulate iron solubility in size. Compared to mineral dust aerosols, iron from combustion sources could be more soluble, and found more frequently in smaller particles. Internal mixing of alkaline dust with iron-containing minerals could significantly reduce iron dissolution in large dust aerosols due to the buffering effect, which may, in contrast, yield higher solubility in smaller particles externally mixed with alkaline dust (Ito and Feng, 2010). Here, we extend the modeling study of Ito and Feng (2010) to investigate atmospheric processing of mineral aerosols from African dust. In contrast to Asian dust, we used a slower dissolution rate for African dust in the fine mode. We compare simulated fractional iron solubility with observations. The inclusion of alkaline compounds in aqueous chemistry substantially limits the iron dissolution during long-range transport to the Atlantic Ocean: only a small fraction of iron (<0.2%) dissolves from illite in coarsemode dust aerosols with 0.45% soluble iron initially. In contrast, a significant fraction (1-1.5%) dissolves in fine-mode dust aerosols due to the acid mobilization of the iron-containing minerals externally mixed with carbonate minerals. Consequently, the model generally reproduces higher iron solubility in smaller particles as suggested by measurements over the Atlantic Ocean. Our results imply that the dissolution of iron in African dust is generally slower than that in Asian dust. Conventionally, dust is assumed as the major supply of bioavailable iron with a constant solubility at 1-2% to the remote ocean. Therefore, the timing and location of the atmospheric iron input to the ocean with detailed modeling of atmospheric processing could be different from those previously assumed. Past and future changes in aerosol supply of bioavailable iron might play a greater role in the nutrient supply for phytoplankton production in the upper ocean, as global warming has been predicted to intensify stratification and reduce vertical mixing from the deep ocean. Thus the feedback of climate change through ocean uptake of carbon dioxide as well as via aerosol-cloud interaction might be modified by the inclusion of iron chemistry in the atmosphere.

Asymptotically Lifshitz brane-world black holes  

SciTech Connect

We study the gravity dual of a Lifshitz field theory in the context of a RSII brane-world scenario, taking into account the effects of the extra dimension through the contribution of the electric part of the Weyl tensor. We study the thermodynamical behavior of such asymptotically Lifshitz black holes. It is shown that the entropy imposes the critical exponent z to be bounded from above. This maximum value of z corresponds to a positive infinite entropy as long as the temperature is kept positive. The stability and phase transition for different spatial topologies are also discussed. - Highlights: Black-Right-Pointing-Pointer Studying the gravity dual of a Lifshitz field theory in the context of brane-world scenario.

Modeling Flows Around Merging Black Hole Binaries  

E-Print Network (OSTI)

Coalescing massive black hole binaries are produced by the mergers of galaxies. The final stages of the black hole coalescence produce strong gravitational radiation that can be detected by the space-borne LISA. In cases where the black hole merger takes place in the presence of gas and magnetic fields, various types of electromagnetic signals may also be produced. Modeling such electromagnetic counterparts of the final merger requires evolving the behavior of both gas and fields in the strong-field regions around the black holes. We have taken a step towards solving this problem by mapping the flow of pressureless matter in the dynamic, 3-D general relativistic spacetime around the merging black holes. We find qualitative differences in collision and outflow speeds, including a signature of the merger when the net angular momentum of the matter is low, between the results from single and binary black holes, and between nonrotating and rotating holes in binaries. If future magnetohydrodynamic results confirm these differences, it may allow assessment of the properties of the binaries as well as yielding an identifiable electromagnetic counterpart to the attendant gravitational wave signal.

Superconducting Cosmic Strings that Connected a Charged Black Hole and Considered as Hair of Black Hole  

E-Print Network (OSTI)

This paper describes that the superconducting cosmic strings can be connected to an electrically charged black hole, and can be considerd as the hair of black hole. What the no-hair theorems show is that a large amount of information is lost when a body collapses to form a black hole. In addition, the no-hair theorem has not been proved for the Yang-Mills field. This paper proves and claims that the superconducting cosmic strings can be connected to an electrically charged hole when the current inside these strings and black holes approaches the critical value. Because, this state is the final state of the gravitational collapse, and the event horizon would be destroyed in this state. Therefore, these strings should be considered as hair of the charged black holes, and may be titled as BHCS (Black Hole Connected Strings). This means that at least the charged black holes have the hair. Thus, the no-hair theorem is not applicable for the charged black holes in the state of the critical current.

Rotating black hole thermodynamics with a particle probe  

Science Conference Proceedings (OSTI)

The thermodynamics of Myers-Perry black holes in general dimensions are studied using a particle probe. When undergoing particle absorption, the changes of the entropy and irreducible mass are shown to be dependent on the particle radial momentum. The black hole thermodynamic behaviors are dependent on dimensionality for specific rotations. For a 4-dimensional Kerr black hole, its black hole properties are maintained for any particle absorption. 5-dimensional black holes can avoid a naked ring singularity by absorbing a particle in specific momenta ranges. Black holes over 6 dimensions become ultraspinning black holes through a specific form of particle absorption. The microscopical changes are interpreted in limited cases of Myers-Perry black holes using Kerr/CFT correspondence. We systematically describe the black hole properties changed by particle absorption in all dimensions.

Black Holes or Frozen Stars? A Viable Theory of Gravity without Black Holes  

E-Print Network (OSTI)

Do observations of black hole candidates rule out alternative theories of gravity without horizon formation? This depends on the existence, viability and reasonableness of alternative theories of gravity without black holes. Here a theory of gravity without black hole horizon formation is presented. The gravitational collapse stops shortly before horizon formation and leaves a stable frozen star. In the limit $\\Xi, \\Upsilon\\to 0$ the Einstein equations of GR are recovered, and the frozen stars become observationally indistinguishable from GR black holes. The theory therefore provides a counterexample to recent claims that observational evidence from black hole candidates "all but requires the existence of a horizon". The theory presented here shares its equations with RTG. Nonetheless, as is shown, there remain important conceptual and physical differences. In particular, some serious problems of RTG are not present in the theory proposed here. So it can be argued that the theory is a physically viable and conceptually sound alternative to GR.

Investigating Dark Energy with Black Hole Binaries  

E-Print Network (OSTI)

The accelerated expansion of the universe is ascribed to the existence of dark energy. Black holes accretion of dark energy induces a mass change proportional to the energy density and pressure of the background dark energy fluid. The time scale during which the mass of black holes changes considerably is too long relative to the age of the universe, thus beyond detection possibilities. We propose to take advantage of the modified black hole masses for exploring the equation of state $w[z]$ of dark energy, by investigating the evolution of supermassive black hole binaries on a dark energy background. Deriving the signatures of dark energy accretion on the evolution of binaries, we find that dark energy imprints on the emitted gravitational radiation and on the changes in the orbital radius of the binary can be within detection limits for certain supermassive black hole binaries. In this talk I describe how binaries can provide a useful tool in obtaining complementary information on the nature of dark energy, based on the work done with A.Kelleher.

The Environmental Impact of Supermassive Black Holes  

E-Print Network (OSTI)

The supermassive black holes observed at the centers of almost all present-day galaxies, had a profound impact on their environment. I highlight the principle of self-regulation, by which supermassive black holes grow until they release sufficient energy to unbind the gas that feeds them from their host galaxy. This principle explains several observed facts, including the correlation between the mass of a central black hole and the depth of the gravitational potential well of its host galaxy, and the abundance and clustering properties of bright quasars in the redshift interval of z~2-6. At lower redshifts, quasars might have limited the maximum mass of galaxies through the suppression of cooling flows in X-ray clusters. The seeds of supermassive black holes were likely planted in dwarf galaxies at redshifts z>10, through the collapse of massive or supermassive stars. The minimum seed mass can be identified observationally through the detection of gravitational waves from black hole binaries by Advanced LIGO or LISA. Aside from shaping their host galaxies, quasar outflows filled the intergalactic medium with magnetic fields and heavy elements. Beyond the reach of these outflows, the brightest quasars at z>6 have ionized exceedingly large volumes of gas (tens of comoving Mpc) prior to global reionization, and must have suppressed the faint end of the galaxy luminosity function in these volumes before the same occurred through the rest of the universe.

Simulations of Jets Driven by Black Hole Rotation  

E-Print Network (OSTI)

The origin of jets emitted from black holes is not well understood, however there are two possible energy sources, the accretion disk or the rotating black hole. Magnetohydrodynamic simulations show a well-defined jet that extracts energy from a black hole. If plasma near the black hole is threaded by large-scale magnetic flux, it will rotate with respect to asymptotic infinity creating large magnetic stresses. These stresses are released as a relativistic jet at the expense of black hole rotational energy. The physics of the jet initiation in the simulations is described by the theory of black hole gravitohydromagnetics.

North American Natural Gas Markets  

Science Conference Proceedings (OSTI)

This report summarizes die research by an Energy Modeling Forum working group on the evolution of the North American natural gas markets between now and 2010. The group's findings are based partly on the results of a set of economic models of the natural gas industry that were run for four scenarios representing significantly different conditions: two oil price scenarios (upper and lower), a smaller total US resource base (low US resource case), and increased potential gas demand for electric generation (high US demand case). Several issues, such as the direction of regulatory policy and the size of the gas resource base, were analyzed separately without the use of models.
