Bhattacharya-102512 Bhattacharya-102512 MATERIALS SCIENCE COLLOQUIUM SPEAKER: Anand Bhattacharya Materials Science Division and Center for Nanoscale Materials Argonne National Laboratory TITLE: "Digital Synthesis: A Pathway to New Materials in the Complex Oxides " DATE: Thursday, October 25, 2012 TIME: 11:00 a.m. PLACE: Building 200 / Auditorium Refreshments will be served at 10:45 a.m. ABSTRACT: The complex oxides have set the stage for some of the most striking phenomena in condensed matter, including high-temperature superconductivity and colossal magnetoresistance. These collective properties emerge as a result of strong correlations between the various degrees of freedom within these materials. In recent years, it has become possible to create artificial structures where complex oxides with diverse

Research Summary: Research Summary: The complex oxides have been fertile ground for strong correlations, giving rise to properties that range from high-temperature superconductivity to room temperature multiferroic behavior. In my research program, we explore new ways to realize and manipulate collective states in the complex oxides. Our approach can be broadly classified into two themes: (i) Interfaces between complex oxides where the electronic and lattice degrees of freedom may 'reconstruct', and lead to novel collective states. (ii) Nanoscale confinement of complex oxides, including phase separated materials. We synthesize our materials in atomic layer-by-layer manner using an ozone-assisted oxide-MBE system, which I designed. This technique allows us to create heterostructures and superlattices with atomically sharp interfaces

Please tell us about your position as department head in charge of Fermilab's Neutron Therapy Facility. The Neutron Therapy Facility started in 1976. Between 1976 and 1985 it was run as a research project funded by the National Cancer Institute. It had a fairly large budget and was able to run a complete clinical program, treating the patients for free and supporting research staff to make developments in the field, publications, attend conferences, and generally advance the subject. In 1985 the grant terminated but the physicians, Drs. Hendricksen (Rush) and Cohen (University of Chicago) decided they wanted to continue to operate. They formed a partnership called the Midwest Institute for Neutron

Poll of radiation health scientists  

SciTech Connect

A sampling of 210 university-employed radiation health scientists randomly selected from the membership lists of the Health Physics Society and the Radiation Research Society was polled in a secret ballot. The results support the positions that the public's fear of radiation is substantially greater than realistic, that TV, newspapers and magazines substantially exaggerate the dangers of radiation, that the amount of money now being spent on radiation protection is sufficient, and that the openness and honesty of U.S. government agencies about dangers of radiation were below average before 1972 but have been above average since then. Respondents give very high credibility ratings to BEIR, UNSCEAR, ICRP, and NCRP and to the individual scientists associated with their reports, and very low credibility ratings to those who have disputed them.

Agricultural scientists cut alcohol fuel costs  

Science Conference Proceedings (OSTI)

Scientists at the US Department of Agriculture have succeeded in lowering the cost of making alcohol from corn by 15 cents to $1.64 per gallon. The cost of drying distillers' solubles dropped because at the end of each cooking/fermenting/distilling run, the solubles are used for cooking, cooling and fermenting in the next run. One evaporation of solubles is required after 10 runs, so energy cost is cut from 17 cents to 1.7 cents. The protein by-products recovered, can be used as swine and poultry feeds and as human food.

Emeritus scientists, mathematicians, and engineers handbook  

SciTech Connect

The Emeritus Scientist, Mathematicians and Engineers (ESME) program is designed to supplement the teaching of math and science in primary schools. The program targets schools where youngsters have little or no contact with these professions. Purpose is to tap into the vast bases of knowledge, training, and experience of retired professionals and use them as a resource and a catalyst for learning. They make a limited commitment to work with a class for one unit of time (six 1- hour sessions plus a field trip, over a 6-week period); this does not include preparation time. Professionals interested in being part of ESME must first prepare a Profile''; a sample profile is given. ESME volunteers presently are working in 8 schools in Washington DC Metropolitan area. Experiments that have been done successfully are listed, as are possible field trips.

Greenhouse effect already here. Scientists call for action  

SciTech Connect

This summer, as one of the century's worst heat waves and droughts plagued much of the United States, a climatologist from the National Aeronautics and Space Administration told a Senate committee that high global temperatures over the past few years can almost certainly be attributed to the greenhouse effect. It was the first time that a scientist had so publicly and positively linked recent weather patterns with the global climate changes predicted to occur in response to increasing carbon dioxide and other greenhouse gases in the atmosphere. Other scientists have remained cautious, maintaining that higher temperatures over the past few years can be explained by natural climate fluctuations. Nevertheless, scientists and many policy makers are calling for action on the greenhouse effect.

Summary of safeguards interactions between Los Alamos and Chinese scientists  

Science Conference Proceedings (OSTI)

Los Alamos has been collaborating since 1984 with scientists from the Chinese Institute of Atomic Energy (CIAE) to develop nuclear measurement instrumentation and safeguards systems technologies that will help China support implementation of the nonproliferation treaty (NPT). To date, four Chinese scientists have visited Los Alamos, for periods of six months to two years, where they have studied nondestructive assay instrumentation and learned about safeguards systems and inspection techniques that are used by International Atomic Energy Agency (IAEA) inspectors. Part of this collaboration involves invitations from the CIAE to US personnel to visit China and interact with a larger number of Institute staff and to provide a series of presentations on safeguards to a wider audience. Typically, CIAE scientists, Beijing Institute of Nuclear Engineering (BINE) staff, and officials from the Government Safeguards Office attend the lectures. The BINE has an important role in developing the civilian nuclear power fuel cycle. BINE is designing a reprocessing plant for spent nuclear fuel from Chinese nuclear Power reactors. China signed the nonproliferation treaty in 1992 and is significantly expanding its safeguards expertise and activities. This paper describes the following: DOE support for US and Chinese interactions on safeguards; Chinese safeguards; impacts of US-China safeguards interactions; and possible future safeguards interactions.

ALS Scientists Patent Technique To ALS Scientists Patent Technique To Dramatically Advance Grating-Based Spectroscopy ALS Scientists Patent Technique To Dramatically Advance Grating-Based Spectroscopy Print Tuesday, 29 January 2013 16:28 Gratings - optical elements used to separate light in spectroscopy applications - have been in use since the early 19th century. Developments in the late 19th century led to the manufacture of gratings by highly precise ruling with a diamond onto a metallic surface. Many gratings are still produced today using the same technique. Holographic methods and ion etching are also used, but all of these techniques result in gratings that contain significant imperfections, which limits resolution. Watch a video about this topic... However, a new type of ultra-high diffraction grating recently patented by members of the ALS Experimental Systems Group (ESG), working with colleagues from Berkeley Lab's Center for X-ray Optics, stands to revolutionize the resolution capabilities of soft x-ray spectroscopy.

ALS Scientists Patent Technique To Dramatically ALS Scientists Patent Technique To Dramatically Advance Grating-Based Spectroscopy ALS Scientists Patent Technique To Dramatically Advance Grating-Based Spectroscopy Print Gratings - optical elements used to separate light in spectroscopy applications - have been in use since the early 19th century. Developments in the late 19th century led to the manufacture of gratings by highly precise ruling with a diamond onto a metallic surface. Many gratings are still produced today using the same technique. Holographic methods and ion etching are also used, but all of these techniques result in gratings that contain significant imperfections, which limits resolution. Watch a video about this topic... However, a new type of ultra-high diffraction grating recently patented by members of the ALS Experimental Systems Group (ESG), working with colleagues from Berkeley Lab's Center for X-ray Optics, stands to revolutionize the resolution capabilities of soft x-ray spectroscopy. The key to the new technique is the production of a near atomically perfect substrate, using the anisotropic etching of silicon.

Scientists studying the greenhouse effect challenge fears of global warming  

SciTech Connect

The author discusses the controversy in the scientific community about the significance of the increased gases causing the greenhouse effect to be detrimental to the earth's ecosystems. He states that the most important aspect of the controversy is the fact that governments are embarking on foolish activities in order to prevent global warming. The fact that scientists offer research with contradicting results furthers the confusion as to what the best course of action is. The government agencies that control policy need to appropriate funds to study specific climatic changes and what effect carbon dioxide and other gases have on the atmosphere.

Knowledge Recombination across Technological Boundaries: Scientists versus Engineers  

E-Print Network (OSTI)

Building on the seminal work of Allen (1977), we contribute to the emerging micro-level theory of knowledge recombination by examining how individual-level characteristics of inventors affect the breadth of their technological recombinations. Our data set combines information from 30,550 European patents with matched survey data obtained from 1,880 inventors. The analysis supports the view that inventors with a scientific education are more likely to generate patents that span technological boundaries (in our case, 30 broad, top-level technological domains) than inventors with an engineering degree. A doctoral degree is associated with increased recombination breadth for all groups of inventors. The breadth of an inventors technological recombinations diminishes with increasing temporal distance to his education, but the differences between scientists and engineers persist over time. Our findings provide several new insights for research on inventors, the literature on organizational learning and innovation, and for strategy research.

A review of High Performance Computing foundations for scientists  

E-Print Network (OSTI)

The increase of existing computational capabilities has made simulation emerge as a third discipline of Science, lying midway between experimental and purely theoretical branches [1, 2]. Simulation enables the evaluation of quantities which otherwise would not be accessible, helps to improve experiments and provides new insights on systems which are analysed [3-6]. Knowing the fundamentals of computation can be very useful for scientists, for it can help them to improve the performance of their theoretical models and simulations. This review includes some technical essentials that can be useful to this end, and it is devised as a complement for researchers whose education is focused on scientific issues and not on technological respects. In this document we attempt to discuss the fundamentals of High Performance Computing (HPC) [7] in a way which is easy to understand without much previous background.

LLNL Scientists Use NERSC to Advance Global Aerosol Simulations  

Science Conference Proceedings (OSTI)

While ''greenhouse gases'' have been the focus of climate change research for a number of years, DOE's ''Aerosol Initiative'' is now examining how aerosols (small particles of approximately micron size) affect the climate on both a global and regional scale. Scientists in the Atmospheric Science Division at Lawrence Livermore National Laboratory (LLNL) are using NERSC's IBM supercomputer and LLNL's IMPACT (atmospheric chemistry) model to perform simulations showing the historic effects of sulfur aerosols at a finer spatial resolution than ever done before. Simulations were carried out for five decades, from the 1950s through the 1990s. The results clearly show the effects of the changing global pattern of sulfur emissions. Whereas in 1950 the United States emitted 41 percent of the world's sulfur aerosols, this figure had dropped to 15 percent by 1990, due to conservation and anti-pollution policies. By contrast, the fraction of total sulfur emissions of European origin has only dropped by a factor of 2 and the Asian emission fraction jumped six fold during the same time, from 7 percent in 1950 to 44 percent in 1990. Under a special allocation of computing time provided by the Office of Science INCITE (Innovative and Novel Computational Impact on Theory and Experiment) program, Dan Bergmann, working with a team of LLNL scientists including Cathy Chuang, Philip Cameron-Smith, and Bala Govindasamy, was able to carry out a large number of calculations during the past month, making the aerosol project one of the largest users of NERSC resources. The applications ran on 128 and 256 processors. The objective was to assess the effects of anthropogenic (man-made) sulfate aerosols. The IMPACT model calculates the rate at which SO{sub 2} (a gas emitted by industrial activity) is oxidized and forms particles known as sulfate aerosols. These particles have a short lifespan in the atmosphere, often washing out in about a week. This means that their effects on climate tend to be more regional, occurring near the area where the SO{sub 2} is emitted. To accurately study these regional effects, Bergmann needed to run the simulations at a finer horizontal resolution, as the coarser resolution (typically 300km by 300km) of other climate models are insufficient for studying changes on a regional scale. Livermore's use of CAM3, the Community Atmospheric Model which is a high-resolution climate model developed at NCAR (with collaboration from DOE), allows a 100km by 100km grid to be applied. NERSC's terascale computing capability provided the needed computational horsepower to run the application at the finer level.

Transit of Venus and Earth-Sun Distance Transit of Venus and Earth-Sun Distance Name: Denise Status: student Grade: 12 Country: Philippines Date: Spring 2012 Question: How do scientists determine the distance of Earth from Sun through the Transit of Venus? Replies: Dear Denise, This is a very good question. The way they calculated it was to use (1) as precise longitudes they could find, and (2) precise timings of first and last contacts of the transits. From these data they were able to arrive at a value for the distance between Earth and Sun. The problem was (besides weather) that the back drop effect prevented accurate timings. A transit of Venus takes place Venus is directly between Earth and Sun. You can imagine two big triangles in the sky, one whose base is on the Earth and whose apex is at Venus The other has its base on the Sun and its apex on Venus. They can use observers at different places on Earth to produce slightly different triangles. Then they can use trigonometry to calculate the distance. Using this method can work only if observations are made from points widely separated on the Earth's surface. Knowing the distance between these points on Earth, one can calculate the distance between Earth and Sun.

Permanence of Ocean Currents Permanence of Ocean Currents Name: Teresia Status: student Grade: 6-8 Country: Tanzania Date: Winter 2011-2012 Question: Are ocean currents permanent? Replies: Teresia: Although many ocean currents have been around for many thousands or years, they can and do change over time. One of the problems some scientists see with global warming is that some currents may shift or stop all together. For example, some folks, are worried that much fresh water may flow into the sea from melting ice in Greenland This would, they say, stop the Gulf Stream in the Atlantic ocean which keeps Europe warm That would plunge Europe into another ice age. But, on the whole, ocean currents do not change over the life of a human being. Mr.Avakian Teresia, Since ocean currents are controlled by several factors: wind - which is the main cause of the different rotations in the northern and southern hemisphere, salinity - which, for example is the main factor in the southward diffusion from the north pole in the Atlantic ocean and the gulf stream, temperature, general ocean floor topography, etc. - changes (on a geological time scale) will cause changes in the ocean currents.

New Classes of Codes for Cryptologists and Computer Scientists  

E-Print Network (OSTI)

In this book, we have introduced several new classes of codes to aid cryptologists and computer scientists. We have explained these codes very non-technically so that a strong mathematical foundation is not needed to understand them. This book also provides an easy method to detect and correct errors that occur during transmission. Further, some of the codes are constructed so as to mislead an intruder/ hacker. False n-codes, whole n-codes can serve this pupose. These codes can be used to ensure security in networks and safe transmission of identity. We have named a few new classes of codes after Periyar, the south-Indian social leader, to mark his services to humanity. This book is divided into three chapters. Chapter one is introductory in nature. The notion of bicodes and their generalization, and n-codes are introduced in the second chapter. Periyar linear codes are introduced in the third chapter. We have used two methods, viz. pseudo best n-approximations and n-coset leader properties to detect and correct errors.

Scientists in a Changed Institutional Environment: Subjective Adaptation and Social Responsibility Norms in Russia  

Science Conference Proceedings (OSTI)

How do scientists react when the institutional setting in which they conduct their work changes radically? How do long-standing norms regarding the social responsibility of scientists fare? What factors influence whether scientists embrace or reject the new institutions and norms? We examine these questions using data from a unique survey of 602 scientists in Russia, whose science system experienced a sustained crisis and sweeping changes in science institutions following the collapse of the Soviet Union. We develop measures of how respondents view financing based on grants and other institutional changes in the Russian science system, as well as measures of two norms regarding scientists social responsibility. We find that the majority of scientists have adapted, in the sense that they hold positive views of the new institutions, but a diversity of orientations remains. Social responsibility norms are common among Russian scientists, but far from universal. The main correlates of adaptation are age and current success at negotiating the new institutions, though prospective success, work context, and ethnicity have some of the hypothesized associations. As for social responsibility norms, the main source of variation is age: younger scientists are more likely to embrace individualistic rather than socially-oriented norms.

An Approach to Evaluate Scientist Support in Abstract Workflows and Provenance Traces  

Science Conference Proceedings (OSTI)

Abstract workflows are useful to bridge the gap between scientists and technologists towards using computer systems to carry out scientific processes. Provenance traces provide evidence required to validate results and support their reuse. Assuming both technologies are based on formal semantics, a knowledge-based system that consistently merges both technologies is useful for scientists that produce data to document their data collecting and transformation processes; it is also useful for scientists that reuse data to assess scientific processes and resulting datasets produced by others. While evaluation of each technology is necessary for a given application, this work discusses their combined evaluation. The claim is that both technologies should complement each other and align consistently to a scientists perspective in order to be effective for science. Evaluation criteria are proposed based on lessons learned and exemplified for discussion.

NEWTON, Ask a Scientist at Argonne National Labs  

NLE Websites -- All DOE Office Websites (Extended Search)

Stellar Motion Reference Point Stellar Motion Reference Point Name: Dylan Status: student Grade: 6-8 Location: CA Country: USA Date: Spring 2012 Question: How can scientists conclude that the Sun and other Stars move? I know it seems pretty simple, but what would they use as a reference point? Replies: There are sophisticated methods but a simple one that works for the Sun, Moon and Planets is to observe their motion against the background of stars that do not appear to move at all. High resolution observation of the reference background of stars show that they too move with respect to other stars, but that is a much smaller motion. Vince Calder Dylan, You are right in thinking that this is not as straight-forward as it sounds. If you are in a car traveling at 55 miles per hour and alongside you is another car traveling at 55 - it would appear that both of you are not moving - unless you can reference the sidewalk or electrical poles by the side of the road. ... and that is the key here, if you compare an object to yourself - say you and a friend are both on skateboards - and you observe your friend as moving, you can only say that your friend is moving relative to your position. In reality, you could be moving and your friend is not, you are stationary and your friend is moving, or both of you are moving at different speeds. What Einstein said about this is that it does not matter which of these conditions you accept, the math and the conclusions about motions and positions will still come out the same. So one way to answer your question is to say, we can just use Earth as the reference point (say that it is not moving) and any observed motion of other objects are a function of their motion relative to Earth - whatever conclusions we derive would still be the same as if the other objects were not moving and only Earth was moving.

Scientist-Teacher Partnerships as Professional Development: An Action Research Study  

SciTech Connect

SUBMITTED AS A DOCTORAL DISSERTATION IN COMPLETION OF REQUIREMENTS FOR THE DEGREE OF ED.D THROUGH WASHINGTON STATE UNIVERSITY. The overall purpose of this action research study was to explore the experiences of ten middle school science teachers involved in a three-year partnership program between scientists and teachers at a Department of Energy national laboratory, including the impact of the program on their professional development, and to improve the partnership program by developing a set of recommendations based on the studys findings. This action research study relied on qualitative data including field notes recorded at the summer academies and data from two focus groups with teachers and scientists. Additionally, the participating teachers submitted written reflections in science notebooks, participated in open-ended telephone interviews that were transcribed verbatim, and wrote journal summaries to the Department of Energy at the end of the summer academy. The analysis of the data, collaboratively examined by the teachers, the scientists, and the science education specialist acting as co-researchers on the project, revealed five elements critical to the success of the professional development of science teachers. First, scientist-teacher partnerships are a unique contribution to the professional development of teachers of science that is not replicated in other forms of teacher training. Second, the role of the science education specialist as a bridge between the scientists and teachers is a unique and vital one, impacting all aspects of the professional development. Third, there is a paradox for classroom teachers as they view the professional development experience from two different lenses that of learner and that of teacher. Fourth, learning for science teachers must be designed to be constructivist in nature. Fifth, the principles of the nature of science must be explicitly showcased to be seen and understood by the classroom teacher.

Before 1984, many scientists believed that high-quality gallium indium phosphide (GaInP) alloys could not be grown for use as semiconductors because the alloys would separate. One researcher at the Solar Energy Research Institute (SERI) thought differently. His name was Jerry Olson, and his innovative thinking changed solar history. Olson identified a material combination that allowed the multijunction cell to flourish. It is now the workhorse that powers satellites and the catalyst for renewed interest in concentrator photovoltaic (CPV) products.

PUS0MOWN-I i Understanding Outrage: How Scientists Can Help Bridge the Risk Perception Gap  

E-Print Network (OSTI)

The popular press often portrays environmental health risks as scarier than most scientists would portray them. The press tends to present these risks from the general public's perspective. This paper describes a widely used approach to understanding how the views of scientists and the public differ and gives an example of how the gap between these views can be bridged. Because the media's presentation of environmental health issues is key in establishing the terms of public discourse, such an approach can further fruitful dialogue in the policymaking process. The task is to help define a research agenda for protecting children-and thus all of us-from environmental health hazards. Because this agenda will ultimately be some combination of the ideas put forward by scientists, public health officials, and the public, the role of the media is critical in this policy-development process. Reporters are the link between scientists and the public. This paper provides a framework for understanding the ways in which scientists and the public view and define risk. How we all perceive risks is key to decisionmaking about the investment of research funds. Newspapers and magazines, television and radio, and on-line news services and bulletin boards report to us daily about conflicting views between scientists and the public. An example is the series of experiments using radiation that were carried out by various government agencies during the

Role of military scientists and engineers in space (1980-2000)  

SciTech Connect

The Space Transportation System provides military scientists and engineers exciting new capabilities to conduct a variety of pioneering experiments on orbit, taking unique advantage of the space environment itself or observing the planet firsthand from the vantage point of space. The reusable Shuttle/Spacelab configuration permits a more effective use of the human and material resources being committed to the space program in the next decade, and ensures the presence of man in space on a routine basis. However, full-scale exploitation of space for national defense will depend to a great extent on the skillful and successful utilization of the military payload specialists, who will fly and operate various Shuttle-based DoD experiments. This paper explores the doctrine, role, function, and training requirements for DoD payload specialists. The unique advantage of man-in-the-loop activities and the orbiting military scientist conducting experiments in situ is addressed in light of previous US manned space flight experience and the projected capabilities of the Shuttle. 4 figures.

Scientists and artists: ""Hey! You got art in my science! You got science on my art  

SciTech Connect

The pairing of science and art has proven to be a powerful combination since the Renaissance. The combination of these two seemingly disparate disciplines ensured that even complex scientific theories could be explored and effectively communicated to both the subject matter expert and the layman. In modern times, science and art have frequently been considered disjoint, with objectives, philosophies, and perspectives often in direct opposition to each other. However, given the technological advances in computer science and high fidelity 3-D graphics development tools, this marriage of art and science is once again logically complimentary. Art, in the form of computer graphics and animation created on supercomputers, has already proven to be a powerful tool for improving scientific research and providing insight into nuclear phenomena. This paper discusses the power of pairing artists with scientists and engineers in order to pursue the possibilities of a widely accessible lightweight, interactive approach. We will use a discussion of photo-realism versus stylization to illuminate the expected beneficial outcome of such collaborations and the societal advantages gained by a non-traditional pa11nering of these two fields.

NREL Scientists Reveal Origin of Diverse Melting Behaviors of Aluminum Nanoclusters (Fact Sheet)  

DOE Green Energy (OSTI)

Research reveals active role of cluster symmetries on the size-sensitive, diverse melting behaviors of metallic nanoclusters, providing insight to understanding phase changes of nanoparticles for thermal energy storage. Unlike macroscopic bulk materials, intermediate-sized nanoclusters with around 55 atoms inherently exhibit size-sensitive melting changes: adding just a single atom to a nanocluster can cause a dramatic change in melting behavior. Microscopic understanding of thermal behaviors of metal nanoclusters is important for nanoscale catalysis and thermal energy storage applications. However, it is a challenge to obtain a structural interpretation at the atomic level from measured thermodynamic quantities such as heat capacity. Using ab initio molecular dynamics simulations, scientists at the National Renewable Energy Laboratory (NREL) revealed a clear correlation between the diverse melting behaviors of aluminum nanoclusters and cluster core symmetries. These simulations reproduced, for the first time, the size-sensitive heat capacities of aluminum nanoclusters, which exhibit several distinctive shapes associated with the diverse melting behaviors of the clusters. The size-dependent, diverse melting behaviors of the aluminum clusters are attributed to the reduced symmetry (from Td {yields} D2d {yields} Cs) with increasing the cluster sizes and can be used to help design thermal storage materials.

1990 National Compensation Survey of Research and Development Scientists and Engineers  

Science Conference Proceedings (OSTI)

This report presents the results of the fourth in a new series of surveys of compensation and benefits for research and development (R D) scientists and engineers (S Es). The 1990 Survey represents the largest nationwide database of its kind, covering 104 establishments which provided data on almost 41,000 degreed researchers in the hard'' sciences. The fundamental nature of the survey has not changed: the focus is still on medium- and large-sized establishments which employ at least 100 degreed S Es in R D. The 1990 Survey contains data which cover about 18% of all establishments eligible to participate, encompassing approximately 18% of all eligible employees. As in the last three years, the survey sample constitutes a fairly good representation of the entire population of eligible establishments on the basis of business sector, geographic location, and size. Maturity-based analyses of salaries for some 34,000 nonsupervisory researchers are provided, as are job content-based analyses of more than 27,000 individual contributors and almost 5000 first level supervisors and division directors. Compensation policies and practices data are provided for 102 establishments, and benefits plans for 62 establishments are analyzed.

Module to guide the expert use of x-ray photoelectron spectroscopy by corrosion scientists  

SciTech Connect

This contribution, to the potential development of data systems having some degree of 'expert' character for use in x-ray photoelectron spectroscopy (XPS), illustrates the manner in which models of 'Rules' might be developed by the user community. The field of corrosion science is taken as an example of one community of researchers who make regular use of XPS for well defined needs. These 'needs' are redefined as a series of Goals that have to be reached in order to characterize the surface in terms of layer sequences and the enrichment of given elements within them. Rules are written to allow a structured approach to achieve each Goal. A feature of this set of Rules is that they are designed expressly to allow automated interpretation of the survey scan. This approach is facilitated by the use of a recommendation that the survey spectrum be acquired as a series of accumulated scans instead of the usual approach of making a single scan through the spectrum. Repeat scans enable the information extracted by the operation of the Rules to be processed and displayed for information during the period that is normally used for the survey scan. It is intended that this information will inform the setting up of any subsequent high resolution scans and their interactive interpretation. It will also inform any future operations such as ion etching or angle-resolved measurements. In some cases, the information made available may be all that is required by the user and in this case the 'expert module' approach becomes particularly cost effective. The operation of the rules is illustrated throughout by an examination of data obtained for passivated stainless steel, giving a data set of measurements, typical of those made by corrosion scientists, that can be compared with the literature values obtained by more conventional XPS interpretation.

Pilot Project on Women and Science. A report on women scientists at the University of New Mexico and Los Alamos National Laboratory  

SciTech Connect

In the fall of 1991, through the coordinating efforts of the University of New Mexico and Los Alamos National Laboratory, the Pilot Project on Women and Science was initiated as a year-long study of women scientists at both the university and the laboratory. Its purpose was to gather information directly from women scientists in an attempt to analyze and make recommendations concerning the professional and cultural environment for women in the sciences. This report is an initial attempt to understand the ways in which women scientists view themselves, their profession, and the scientific culture they inhabit. By recording what these women say about their backgrounds and educational experiences, their current positions, the difficult negotiations many have made between their personal and professional lives, and their relative positions inside and outside the scientific community, the report calls attention both to the individual perspectives offered by these women and to the common concerns they share.

Several compensation characteristics of DOE contractor-operated laboratories are compared with those reported in the 1980 National Survey of Compensation Paid Scientists and Engineers Engaged in Research and Development Activities. The data are as of August 1, 1980. A total of 339 establishments (industry, Federal laboratories, Federal contract research centers, nonprofit research institutes, educational institutions) and 18 DOE laboratories are included in the survey. Characteristics of DOE laboratories such as salaries by field of degree, maturity, and management levels are shown and are compared with the National Survey patterns. Approximately 8 out of 10 S and E's at DOE Laboratories (84.8%) held a degree in one of four fields: engineering, chemistry, physics, or mathematics/statistics. In the National Survey, 78.5% of all S and E's held degrees in these fields. The average DOE Laboratory S and E salary increased 6.6% between 1979 and 1980, while the average salary in the National Survey advanced by 7.5%. The National Survey percentage increase over the year was greater at each degree level than among DOE Laboratories.

appear today. My expertise is studying land vegetation using Earth orbiting satellites. I am assigned by NASA to the United States (US) Climate Change Science Program (CCSP) in Washington, where I co-chair the Observations Interagency Working Group. I have provided my resume for your information. NASAs and NOAAs Earth orbiting satellites make measurements that enable our understanding of climate change and the global integrated Earth system. These satellites provide high accuracy, high-spatial and high-temporal resolution, global observations of the atmosphere, ocean, and land surface that cannot be acquired by any other method. To understand climate change, satellite observations must be of sufficient duration to distinguish long-term trends from short-term cycles created by processes such as extreme weather and El Nino. Land vegetation is a critical aspect of the global carbon cycle because plants absorb carbon dioxide from the atmosphere via the process of photosynthesis and incorporate or store this carbon in wood and soil. In the global carbon cycle, carbon is exchanged among the biosphere, geosphere, hydrosphere, and atmosphere (Figure 1). The amount

Wood, bark, and the wax-coated seeds from Chinese tallow tree (Sapium sebiferum (L.) Roxb. syn. Triadica sebifera (L.) Small), an invasive tree species in the southeastern United States, were subjected to extractions and degradative chemical analyses in an effort to better understand the mechanism(s) by which this tree species aggressively competes against native vegetation, and also to facilitate utilization efforts. Analysis of the wood extractives by FTIR spectroscopy showed functionalities analogous to those in hydrolyzable tannins, which appeared to be abundant in the bark; as expected, the seeds had a high wax/oil content (43.1%). Compared to other fast-growing hardwoods, the holocellulose content for the Chinese tallow tree wood was somewhat higher (83.3%). The alpha-cellulose (48.3%) and Klason lignin (20.3%) contents were found to be similar to those for most native North American hardwoods. Results suggest that Chinese tallow tree wood utilization along with commercial wood species should not present any significant processing problems related to the extractives or cell-wall chemistry. Keywords: Cellulose, Chinese tallow tree, extractives, Klason lignin, utilization.

National science policy and scientific manpower: Funding effects on job mobility of scientists and engineers in the United States, 1958--1972  

Science Conference Proceedings (OSTI)

Science policy in the United States between 1958 and 1972 was intended to influence the research and development (R D) labor force indirectly, through government funding. An event history analysis of professional R D jobs in five scientific disciplines shows that, while federal funding influences the job mobility of scientists and engineers, other social and economic factors are also significant in explaining mobility patterns. Federal funding significantly decreases the rates of job mobility in all disciplines during the period, stabilizing the employment structure. Indicators of reward-resource arguments-salary, age, and education-significantly affect job mobility. Consistent with human capital and job matching arguments, salary and age significantly reduce mobility. Education is significant only in life science, physical science, and engineering, where higher education leads to increased mobility. Indicators of limited opportunity arguments-socioeconomic background, sex, and ethnicity-show mixed empirical results. Labour markets also significantly affect mobility. In engineering and physical science, a neo-institutional model, which accounts for the degree of government oversight, fits the data best. Social science and life science are best fit by performance sectors, which highlight the importance of universities as employers for these disciplines. Mathematical science is best fit by a model of industrial sectors, consistent with differential expansion of the economy that disproportionately affected this discipline. Federal funding has acted to institutionalize R D in the economy and stabilize employment; it has not insulated workers from general socioeconomic factors such as human capital, discrimination and labour markets.

Return to Biplanes Return to Biplanes Name: Steven Status: student Grade: 9-12 Country: United Kingdom Date: Fall 2011 Question: As planes have got so large, the wings have become huge. Why can they not go back to biplanes for the same surface area but only half as wide? Replies: Hi Steven, In the early days of aviation, biplanes were a very common design since they could be made very strong using the materials and methods of the time (wooden frames with fabric covering). The two wings would form a strong truss structure with diagonal strut wire or bar bracing. It was not as easy to create a strong wing if there was only one (a monoplane in other words), but even so there were early monoplanes as well. For example, there was the Bleriot XI which crossed the English Channel in 1909. It used quite a bit of wire bracing above and below the wing. While the all the struts and wires did strengthen early airplanes, the downside though was a lot of aerodynamic drag just due to the struts and wires alone.

Eye of Hurricane Eye of Hurricane Name: Xinyi Status: student Grade: 9-12 Location: IL Country: China Date: Spring 2011 Question: Why is the eye of a hurricane so calm? A lot of videos say that it' i because the rising air cools off and sinks down in the eye, but if it is true, I think the eye should have a high pressure, not the lowest pressure of a hurricane. Replies: Cold air is heavier than Hot air and will fall relative to the Hot Air. Hot air will rise relative to Cold air. The eye of a hurricane is calm because the storms rotate around it. The highest winds of the hurricane are in the wall of the eye which is very distinct. The hurricane derives its energy from the relatively hot surface temperature of the sea. The humidity in the hot rising air feeds the heavy rainstorms that form the hurricane. The rising hot, moist air of a hurricane is a counter clockwise rotating cyclone that creates a low pressure area in the eye. So the lowest air pressure point of a hurricane are in the eye

Radio Reception Radio Reception Name: Mark Status: other Grade: other Location: AZ Country: USA Date: Spring 2012 Question: When a cell phone receives radio waves from a cell tower, are the received photons creating an electric current within the metal components of the cell phone antenna? In other words, are the photons being converted into electrons? If so, how is this occurring? Replies: The electrons are already there in the antenna and circuitry. The radio and microwave photons simply push them into motion, which is the electric current. Richard E. Barrans Jr., Ph.D., M.Ed. Department of Physics and Astronomy University of Wyoming Mark, The photons do not become electrons. The photons give energy to the electrons, forcing them to move through the antenna. The radio waves have a specific frequency. The electrons move back and forth through the antenna with that same frequency. This motion of the electrons is the oscillating current that your cell phone amplifies and then translates into the sounds you hear.

Or do you just go to the recipe for the cookies and ignore the rest? The caterpillar's cells and the butterfy's cells both contain the same instruction manual (DNA) but they read different parts of it at different stages of their life cycle.

"Apparent Melting" "Apparent Melting" Name: Bernard Status: educator Grade: 6-8 Location: CA Country: USA Date: Spring 2012 Question: This is about melting. I know you already answered "Wood will not melt." And also, "sugar does not melt, it decomposes." Is there a different name for this, then? Somewhere I saw "apparent melting."? What if wood was heated up in an inert gas environment, and placed under pressure. Could liquid wood then be produced? If it is true sugar does not melt (i.e. a physical change), then what are it is products if it "decomposes" (which is a chemical change)? Replies: Bernard, The reason that some substances decompose rather then melt is because the energy required to break the chemical bonds within the molecule is less than the energy required to break the intermolecular forces holding the molecules in a solid state. Since the melting temperature can be a function of pressure (look at any phase diagrams), it is possible to increase or decrease the temperature of melting and as such it is possible to move the melting temperature above or below the decomposition temperature since decomposition temperature is not as strongly affected by pressure.

Desert Hair Desert Hair Name: Zimin Status: student Grade: 6-8 Location: Outside U.S. Country: Singapore Date: Spring 2012 Question: If hair is used for insulation, why do desert animals like camels have hair? Replies: Keep in mind that "insulation" works both ways -- "insulating" body heat from escaping from a warm body to colder surroundings (hence the fur coat of a polar bear). Compare this with the function of hair on a camel. The hair (fur) limits the absorption of heat by the animal from its hot surroundings. Vince Calder Zimin Principally to protect them from the burning rays of the sun; and to help with water retention. Desert hair, when in sufficient quantities, can protect from biting insects although sometimes it provides refuge to insect vermin, provides coloration for various social purposes and provides warmth during cold desert nights.

Each Substance Unique Density Each Substance Unique Density Name: Colin Status: educator Grade: 6-8 Location: CO Country: USA Date: Winter 2011-2012 Question: Is it true that the density of each substance is unique? (That is my understanding.) So when my students ask, will a substance with a density of 1g/cc float or sink in water, I should tell them that this is a highly unlikely situation because pure, distilled water is the only known substance with that density? Replies: Hi Colin, No, the density of a substance is not a unique property of the substance. Density is not enough to uniquely identify a solid or liquid. It certainly is one of several physical properties that one likes to measure in order to be sure that a substance is what one supposes it to be. Consider carbon. In its graphitic form a sample of carbon will have a density of about 2.2. In the form of diamond, carbon's density is about 3.5. This simple example shows that the manner in which the element is formed results in a phase with a very different density. More generally, one can form various minerals with various densities and there is no guarantee that one of those will not have a density of 1. The same is true with liquids - thousands of new compounds are synthesized every year, and I am willing to bet any money that some of them have a density of 1 g/cc.

Computers Communicating Computers Communicating Name: Billy Status: student Grade: 6-8 Location: FL Country: USA Date: Fall 2011 Question: How do computers talk to each other? Replies: Hi Billy, Great question! Much like how we talk to each other, computers have a common language. For most of us it's English. In addition, computers follow what is called protocol, much like how we follow rules and etiquette. The computer language is made up by an electrical signal and it is either 5 volts or 0 volts. This can be represented as a [1] or a [0]. This one or zero is what is called a bit in the binary language. Binary, meaning two bits of information. The language can be defined so that [1] means "yes" and [0] means " no". But computers can process multiple bits per given time. So adding more bits, gives us more words. Say two bits of information: [00], [01], [10], [11]. Each of these can mean "yes", "no", "maybe", "I do not know".

Seed Numbers Seed Numbers Name: Dan Status: student Grade: n/a Location: N/A Country: USA Date: Summer 2011 Question: Why do some seed plants produce numerous seeds, while others just one? Replies: Hi Dan, When a plant produces seed, the purpose is to carry on the species - to produce more plants. The strategy employed by the plant will vary depending on the environment in which the plant has developed, but in the main there are two main strategies which I categorize in my head as "Special Care" and "Safety in Numbers". "Safety In Numbers" is how the dandelion chooses to tackle the problem. It produces huge numbers of seeds, and does very little to help those seeds other than to make sure they get away from the parent plant (That's trhe job of the parachute) Other plants which use this strategy include most herbs such as mint, borage, dill where the seeds are very small, and are produced in huge numbers.

Melting Salt Versus Dissolving Salt Melting Salt Versus Dissolving Salt Name: Mark Status: student Grade: 9-12 Country: USA Date: Winter 2011-2012 Question: When we try to melt a certain amount of table salt, we have to raise the temperature significantly, but when we drop it into the water, its atoms are easily separated. Where does this energy comes from? Replies: You could consider it a chemical reaction (though easily reversible) between water and salt. When: the component ions of the salt are dispersed in the water and individually hydrated, the overall energy state is lower than when: the ions combine into a salt crystal and the water is someplace separate from it; so the reaction goes forward. You could think of it as potential energy, some energy that has long been stored up, just waiting to be given the kinetic occasion to act (by putting the salt crystal in contact with the water). The world is full of potential energies like that, and industrial civilization lives by finding and activating them.

No Flow in Liquid Container Despite Pressure Difference No Flow in Liquid Container Despite Pressure Difference Name: Chantaiah Status: student Grade: 12 Country: India Date: Winter 2011-2012 Question: Why is it that a liquid in a container cannot flow from bottom to top even though there is a pressure difference? Replies: Chantaiah, The pressure difference for a liquid in a container is due to gravity. The pressure supports the weight of the liquid above it. The pressure at the top supports the atmosphere, countering the atmospheric pressure. The pressure at the bottom of the container supports the atmosphere plus the weight of the liquid within the container. The pressure difference pushes up, but gravity pulls down. The two effects cancel each other, so the liquid just sits still in the container. Dr. Ken Mellendorf Physics Instructor Illinois Central College

Replies: Many plants naturally have abscisic acid within the seeds to prevent sprouting until the spring. http://plantphys.info/seedg/seed.html "Inhibitors Present: Many plant species invest chemicals in the developing seeds, and these chemicals inhibit the development of the embryos. They keep the embryos dormant. Obviously the seed must have some way to eliminate these chemicals before they can sprout." "Abscisic Acid: Many temperate zone species that use inhibitors use abscisic acid. This chemical induces dormancy in the embryo. The chemical is produced in abundance in the late summer and early fall. The seeds in the fruits become dormant so, even if they are dispersed in autumn, they cannot sprout. During the winter enzymes in the seeds degrade the abscisic acid. By spring the abscisic acid is gone and the seed can sprout."

Mica, Gypsum, and Hardness Mica, Gypsum, and Hardness Name: Melissa Status: educator Grade: 4 Location: NC Country: USA Date: Winter 2011-2012 Question: I have a question regarding the hardness of mica and gypsum. Gypsum is a 2 on Moh's hardness scale and mica is somewhere between a 2 and 3. However, mica breaks and scratches very easily by a penny, paper clip, and fingernail and gypsum does not. What is a good way to explain to my students how gypsum is still "softer" on the scale? Obviously, mica breaks apart very easily. Replies: Melissa, Mineral hardness and mineral cleavage are separate issues. Mineral hardness is a measure of a mineral's ability to resist being scratched. Mineral cleavage is the ability for a mineral to split along weakly-bonded atomic planes. The micas have one good mineral cleavage. That is, mica splits nicely in along one plane. Halite (table salt), on the other hand, splits equally well in three orthogonal directions (that is, along three planes, each of which is at 90 degrees to the others). Shake out some table salt on an overhead projector and have the students walk up to the screen. They will see that all salt has cubic mineral cleavage. I don't know how much snow you get in North Carolina, but if you get some salt that is used to melt ice you will note that it too has cubic cleavage. When you break up the large salt crystals you will observe that they break into smaller cubes. When you break the mica, it will break into smaller sheets.

Silica Gel Silica Gel Name: Lisa Status: educator Grade: 9-12 Location: Outside U.S. Country: USA Date: Fall 2011 Question: Can you tell me how silica gel is correctly categorized (I see it called narrow or large pore as well as Type A, B and C)? What is the difference? Are they all used the same way, as a desiccant? Replies: Hi Lisa, The "A", "B" and "C" designations of silica gel refer to the pore size. The "A" type has large numbers of very small pores, and is generally used as a desiccant. Water vapor is adsorbed into these pores, or water vapor already adsorbed, is released upon heating. This is the type normally found in small bags packed in electronic and optical products. The "C" type has somewhat fewer (but still very large numbers) large pores. This type is used for large volumes of liquid water absorption, commonly as cat litter.

On the days when the moon is at half phase, effectively a semi circle , the visible lit side is illuminated by the rising sun. So, using a set square aligned along the moon's visible diameter, and a ruler at right angles, in contact with the square, I expected that the ruler would point directly at the sun. On the days I have tried this the sun always seem to be lower down in the sky than the ruler suggests it should be. Maybe, I guess, as much as 20 degrees off target. Why does the lit half of the moon not seem to always point straight at the sun?

Flightless Birds Flightless Birds Name: Nick Status: student Grade: 6-8 Location: Outside U.S. Country: Canada Date: Winter 2011-2012 Question: Since the bird Emu is flightless, do their wings server another purpose? Also have they always been flightless? Replies: Nick: Emu wings are vestigial, meaning they probably serve no purpose now. The emu as a species is flightless, but most likely evolved from ancestors that had wings. This from http://tolweb.org/treehouses/?treehouse_id=4729 may help. "The Emu has lost almost all need for the function of its wings. Through evolutionary time, their wing skeleton has degraded to only a single functional digit. In accordance with a reduced skeleton, there have been significant reductions in the muscles of the wing, even when comparing the Emu to other non-flying birds. Still, many muscles show diversity in their shape, where they are attached to the bone ,and whether they are even present or not. Evolutionary theory predicts that relaxed selection on vestigial organs should allow more variation to persist in the population, and this corresponds to what is observed in Emu populations."

The shoe has "Load and Launch" technology built into the front sole of the shoe that is some sort of spring mechanism. The way I see it, this mechanism cannot allow a player to jump higher because only an external force can produce motion. The spring mechanism is internal to the body (including the player, shoes, socks uniform) that is launched into the air and an internal force cannot produce motion. Despite this, the shoe has been tested and found to provide additional lift. The shoe has actually been banned by the NBA because it provides an unfair advantage to players who wear them.

Any soil with organic material/humus would likely have some forms of organic and inorganic nitrogen. Sand would also be deficient in nearly all other nutrients, but overall it would allow you to control all nutrients independently. Don You can use the silica (quartz) sand used in fish tanks.

Insolation as Percent of Total Solar Output Insolation as Percent of Total Solar Output Name: Terry Status: student Grade: 9-12 Country: USA Date: Spring 2012 Question: What percentage of the sun's total output do we actually receive on Earth? Replies: Terry, First, imagine a sphere around the Sun with a radius equal to the distance of the Sun to the Earth. Using geometry, calculate the total surface area of this sphere (AS = 4 pr r[of our imagined sphere]^2). The portion of this area that the Earth takes up is the area of the cross-section of the Earth (AE = pi r[of Earth]^2). Dividing AE by AS tells us what fraction of the Sun's output (assuming it is equally dispersed to the surface of our hypothetical sphere) reaches the Earth. Multiplying this by 100 gives percent.

Varying Size of Full Moon Varying Size of Full Moon Name: Marian Status: student Grade: other Country: Australia Date: Spring 2012 Question: Someone said that our full moon on 7/4/12 was the biggest moon for the year, if this is so, why? How is it that the apparent size of the moon changes? Replies: I am not certain about exact dates. It is true, however, that the Moon's orbit about the Earth is not a perfect circle, but an ellipse. The Moon is closer to the Earth at some points in its orbit than at others. If it is full when it is close, it appears bigger in the sky. Richard E. Barrans Jr., Ph.D., M.Ed. Department of Physics and Astronomy University of Wyoming Marian, I do not know about 7/4/12 but I have seen reports that the full moon last 3/18 - 19/12 was the largest observed in 20 years (sorry, I did not actually observe this myself). This was because the moon was in perigee - a point in the moon's orbit that takes it closest to the Earth, and this coincided with a full moon. The moon's orbit around the Earth is not circular, it is elliptical. This means that there will be times that it will be a little bit farther or closer depending on the coincidence of the Earth and Moon orbits as well as the occurrence of the full moon. The moon can appear as much as 14% larger during perigee.

Changing during a Lifetime Changing during a Lifetime Name: Chatta Status: student Grade: 12+ Location: Outside U.S. Country: India Date: Winter 2011-2012 Question: Does DNA change with growth or does it stay exactly the same throughout our life time? Replies: DNA generally does not change drastically over a lifetime. However, DNA expression can change over time based on developmental and/or environmental cues (even though the underlying sequences stay the same). However, during cell division, minor mutations can always crop up. Some are silent while others are disastrous (i.e. cancer). To prevent the likelihood of such genomic disaster, cells are pre-programmed to senesce after a certain number of divisions. This is governed by the Hayflick Limit. This is an extreme case, but there have been documented cases of viruses invading human cells and "exporting" some of their DNA through horizontal gene transfer. The HeLa cell line is one example of a chimeric "hybrid". These cells are cancerous, but highly useful for research because the Hayflick Limit does not apply. They are functionally immortal. br>

Capacitor and Current Capacitor and Current Name: Hadia Status: student Grade: 9-12 Country: Pakistan Date: Spring 2012 Question: How exactly can current pass through a capacitor? Be it A.C or D.C. Even if we consider the general logic that current 'flows through' a capacitor as it charges and discharges via A.C, then in what does the discharged current flow. If it flows through, shouldn't power be dissipated. And if it flows back and what is the use of a capacitor? Even if you say, it flows through, how would you explain it in terms of individual charges? Replies: Hadia, Your question is a natural one because it appears that current flows "through" a capacitor. Indeed, we treat capacitors as though they are resistors in which individual electrons enter on one terminal and exit through the other. A capacitor operates differently. The word "capacitor" implies a device that has "capacity," or a device that has the capability to store a certain amount of charge, somewhat like a "charge bucket." In fact, the formula for capacitance, Q=CV, implies just this storage: The charge stored by a capacitor (Q measured in Coulombs) is given by its capacitance (C measured in Farads) multiplied by the voltage applied to the capacitor (V measured in Volts). Current does not flow through the capacitor as much as into the plates of the capacitor, i.e., into its "charge bucket."

One report said that cosmic ray flux decreased as the mass passed Earth late on Tuesday and Wednesday. Why? I thought it would increase due to all of the energetic particles. Perhaps the sun is NOT part of the source of cosmic rays? Please help me understand this non-intuitive event. Replies: Justin English is a difficult language and sometimes the reading of words do not result in the meaning the author intended. I think the author meant to say that as the solar storm passed by the Earth, the Cosmic Ray Flux decreased. Both of your assumptions are correct. The Cosmic Ray Flux would increase as the storm approached the Earth and peaked and the Sun is not the only source of Cosmic Ray Flux.

Albino Gene Loci Albino Gene Loci Name: Gabreal Status: other Grade: 9-12 Location: Outside U.S. Country: USA Date: Spring 2012 Question: What chromosome is albinism located on? Replies: There are actually many different kinds of albinism which occur due to mutations in different genes. In principle, all forms of albinism share a common trait, namely that affected individuals do not produce melanin, the major pigment protein in our skin. However, there are a wide variety of potential mutations that can lead to this result, and they are located on several different chromosomes. One notable case is of ocular albinisms, which only affect the eyes (and not the skin). These mutations have been shown to be present almost exclusively on the X chromosome. As a result, most individuals affected with X-linked ocular albinism will be male, similar to the genetics of X-linked color blindness.

What I want to know is how it works and/or how many worlds that it can create. Replies: I do not know about the game. But here is the "problem". To generate a "random" number, one starts with a "seed" number of arbitrary length. Then that is then fed into a complex series of computations.

The different "seed" and a different algorithm (which may change from one cycle to the next) gives a certain result, which may again be re-cycled into another algorithm. To a given degree of "accuracy" the final result may be "random". "Randomness" depends upon the choice of "seed", the algorithm, and the number of cycles. I don't know that it has been proven mathematically that a certain procedure the guarantees a "random" number (that is a totally different mathematical problem). That, at the present of the mathematical "art" has not been proven, but that is not my area of expertise.

Our body produces gases and acids like these (eg: Urea) during various metabolic process, which seems impossible because these gases & acids require very high temperatures (~200'C) for their synthesis and the maximum our body can do is 37'C. So how a human body is able to produce gasses and acids like Ammonia, Hydrogen Sulfide, HCl and others at body temperature? Replies: It would help to know the reaction you are using to synthesize ammonia gas (NH3), a base, using HCl, an acid. But putting that aside, realize that there are many reactions that have ammonia as a product. Some of these reactions require high temperature, but many other reactions do not require elevated temperature. What I believe you are thinking about is the reaction of formation of a compound, that is, the formation of a compound, in this case NH3, from its constituent elements -- N2 and H2 -- 1/2 N2 + 3/2 H2 = NH3.

None of the three polymers you mention (polypropylene, nylon, and polyester) are soluble in any solvents, so detection by solvency is not possible. None of the rest of the properties you mention (stretch rate and hydrophobic properties) produce sufficiently clear cut results to be useful. One semi-reliable way to tell them apart is by the smell that results from heating a small sample. Polyolefins such as polypropylene (and polyethylene) smell like heated wax (since these polymers are in essence simply long chain waxes). Nylons also tend to have their own distinctive odor when heated.

Crystalline Solids and Lowest Energy Crystalline Solids and Lowest Energy Name: Maggie Status: student Grade: 9-12 Country: Malaysia Date: Fall 2011 Question: Why does crystalline solid has to be in the lowest energy state? Replies: Maggie, My first thought upon reading your question was: "... lowest energy state - relative to what?" The problem is that yes, crystalline solids have lower energy states compared to the same substance at higher temperatures and different states, but it may also be of a higher energy state relative to other substances at the same temperature. So, maybe let us look at what "crystalline solid" means - and then you can answer the question based on whatever parameters you want to apply. By "solid" we mean that the atoms that make up the substance do not have translational motion. Meaning to say, they may vibrate in place, but on average stay in the same location. This means that there is a higher level of order (lower level of entropy) in solids compared to other phases (liquids and gases) that do have translational mobility. For this reason, when compared to other states, we say solids - everything else being equal - have a lower energy state.

I have asked experts in all four fields and they all seemed puzzled and unaware of the answer. Who designs microwave heating equipment? Replies: In modern science and engineering, the distinctions between academic disciplines are very blurred. There is a strong focus on inter-disciplinary studies because so many disciplines are needed to design everyday things. For example, a home microwave includes chemical engineers (who design the materials), mechanical engineers (who design structural parts made from the materials), electrical engineers (who design the circuitry), industrial engineers (who design the appearance and functionality), physicists (who invented the magnetron powering the microwave source).

Aggressive Dogs Aggressive Dogs Name: Santha Status: student Grade: 9-12 Location: Outside U.S. Country: Australia Date: Fall 2011 Question: What type of aggression classification would you give a dog that attacks other dogs with out any signs or provocations? Replies: Santha, In my experiences of breeding and raising several (related) Jack Russell Terriers, I've observed it is a matter of perceived threat. By this I mean either the aggressive dog IS threatened in some way, or the aggressive dog PERCEIVES a threat when one might not actually exist, and the dog lashes out. I've seen that most of the female dogs I've had did not get along with each other. My explanation for this is that each of them has a relationship of trust and concern with me, and they see another female dogs as a threat to that "relationship". Oddly, all of the female dogs I have had have gotten along ok with each of the males I've had.

Crystalline Metal Versus Metallic Glass and Conduction Crystalline Metal Versus Metallic Glass and Conduction Name: Marilyn Status: student Grade: 12 Country: USA Date: Fall 2011 Question: Which will have a better electrical conductivity, a crystalline metal or a metallic glass. Replies: Hi Marilyn, I was unable to find any direct data on electrical conductivity of amorphous metals, however there is data that appears to suggest the conductivity of amorphous metal is slightly worse than that of the same metal in crystalline form. It is known that amorphous metals have lower thermal conductivity than their crystalline forms, and in most cases decreased thermal conductivity is accompanied by decreased electrical conductivity. It is also known that as a metal's crystal structure becomes finer and more disorganized, electrical conductivity decreases somewhat. An example of this is the case of copper. Annealed copper, which has fewer, larger crystals, has slightly better electrical conductivity than work-hardened copper. Work-hardening copper breaks up the large crystals into much smaller, and more disorganized ones, resulting in its electrical conductivity being slightly reduced. Carrying this to it's logical end, an infinitely small and highly disordered crystal structure would appear much like a metallic glass. From this, therefore, one can surmise that a true amorphous metal will indeed have slightly poorer electrical conductivity than normal crystalline metal of the same type.

Heat Shield and 120 000 Foot Fall Heat Shield and 120 000 Foot Fall Name: John Status: educator Grade: 9-12 Location: OK Country: USA Date: Winter 2011-2012 Question: My classes and I have been looking at the Red Bull/Stratos home page and discussing Felix Baumgartner's future attempt to free fall from 120,000 feet. Why is the build up of heat upon reentry not an issue, if he is expected to reach 700 plus miles per hour? Replies: It might be, but I am sure that has been taken into account. Here are some procedures that might be keep him from turning into a crisp. At high altitude the density of air is low so there would little resistance to avoid heating. I presume he will be outfitted with a heat resistant suit of some sort and a number of sensors to monitor temperature, pressure, and descent speed. As atmospheric pressure increases, his "jump" gear is probably fitted with devices to slow the rate of descent. I would guess the devices would be more complicated than a simple parachute, at least at high rates of fall, but some sort of "parachute" nonetheless to control his descent rate. In addition, I would guess he also has some sort of controllers to keep him from tumbling. At the high speed tumbling could be a worse issue than just speed. With some sort of foils (wings??) he could possibly move around in circles and glide at the same altitude. This would give him time to dissipate the heat. Basically, he would be a glider, dropping in a controlled spiral. He could control the "pitch" of the screw trajectory. Of course, some sort of breathing apparatus would have to be part of his apparatus.

Photon Mass and Gravitation Photon Mass and Gravitation Name: James Status: student Grade: 9-12 Location: MD Country: USA Date: Spring 2012 Question: A sun has mass. This mass causes it to collapse on itself, forming heavier and heavier elements. Eventually the sun will collapse and cause a black hole to form. The Earth also has a mass and gravity also tries to make the Earth collapse like the sun. The Earth however does not collapse like the sun. This occurs because of the quantum mechanical phenomenon known as Pauli's exclusion principle. The Pauli exclusion principle says that two electrons with the same spin state cannot occupy the same quantum orbital state. This prevents the earth from collapsing on itself. A photon has energy using Plank's E=hf equation. Using Einstein's E=mc^2 equation a photon has a relative mass. This relative mass will produce a force known as gravity. This force is explained through Einstein's Theory of General Relativity. Now why does a photon not collapse like the earth? Is there a principle similar to Pauli's exclusion principle that keeps a photon from collapsing? My question is what force combats the gravity of a photon, so that the photon does not collapse on itself and from a black hole like the sun.

Current Oil Formation Current Oil Formation Name: Jerry Status: n/a Grade: other Country: USA Date: Winter 2011-2012 Question: Is oil still being formed in an ongoing fashion by geologic and physical processes just as it was millions of years ago? Replies: Jerry, The process of converting organic detritus into oil only requires that the organic material (dead plants, animals, etc) undergo decomposition in an oxygen poor environment. Long chain hydrocarbons are formed in this way. So in places where there is a lot of organic material buried under rock or below the pinocline of some body of water (a depth and temperature of water where little roiling happens and hence oxygen does not appreciably mix in), then the conversion of organic material into oil should be happening. This might lead you to wonder why are we concerned that fossil fuel is being depleted - and this goes to how much oil is being extracted and used, versus how much oil is being produced by the natural process.

Many plant need soil to grow and make food. What kind of soil need in aquatic plants to grow or this normal soil is used for the aquatic plant? Replies: Dear Maaz, You may recall the famous experiment by Jan Baptist van Helmont where he grew a tree in a large pot with a weighed amount of soil for five years and determined that the bulk dry weight of the tree did not come from the soil but rather from the carbon dioxide drawn from the air (with water contributing to the fresh weight). The experiment demonstrates that the soil is most critical for supplying physical support and trace minerals. In an aquatic environment, the trace minerals are found primarily in the water so the soil largely serves as a means to anchor the aquatic plant and keep it from drifting.

Asteroids, Charge, and Magnetic Fields Asteroids, Charge, and Magnetic Fields Name: Daniel Status: student Grade: 12 Location: MD Country: USA Date: Spring 2012 Question: If a fragment from an asteroid falls to Earth and a static electric charge is built up in the fragment as it falls, does it generate a magnetic field? If so, why? Replies: Yes, it would. A moving electric charge creates a magnetic field. The "why" basically comes from relativity. When the charge moves, its electrical interaction with other charged objects changes because of the way spacetime distorts. That change manifests as a magnetic field. Richard E. Barrans Jr., Ph.D., M.Ed. Department of Physics and Astronomy University of Wyoming Daniel, Current is the motion of electric charge from one location to another. Current, as we usually think of it, is the movement of electrons within a wire, and this current will create a magnetic field surrounding the wire. Maxwell's equations define the strength of this field based on the value of this current (amount of charge flowing through the wire each second). Current is not confined to wires, however; electrons flowing in space will define a current (and associated magnetic field) as well. For a charged asteroid, you can define current associated with its charge moving through space and an associated magnetic field.

Convection Currents in Mantle Convection Currents in Mantle Name: Rasy Status: student Grade: 6-8 Location: CA Country: USA Date: Winter 2011-2012 Question: What causes convection currents in Earth's mantle? Replies: There are two sources of heat we usually think about. First of all, there are radioactive atoms in the deep earth and as they decay, they give off heat (just like a nuclear reactor). The second source is a bit more difficult to understand. The earth formed by a whole pile of particles, dust and what we might call meteorites, collecting together due to gravity. This is called accretion. Every time a new piece of matter hit the new earth it caused heat. Not all the heat escaped because there were too many collisions over too short a time). Now some of that heat is trapped deep underground and fuels the cells.

RNA as a Catalyst RNA as a Catalyst Name: Neeraja Status: other Grade: other Location: Outside U.S. Country: USA Date: Winter 2011-2012 Question: Why is RNA a better catalyst than DNA? Specifically what features of its structure make it better and why? Replies: Neeraja, It's a good question, and my short answer is that it's because nucleic acid enzymes must be single-stranded (ss), and there's a lot more ss-RNA around than ss-DNA. Also, ss-RNA is more flexible than ss-DNA. Adding the two together, you get two strong reasons why RNA is a better chemical for this purpose than DNA. For a little more detail, keep reading: First, let me start with a basic explanation of how catalysis works: A biological catalyst, whether protein or nucleic acid, is a three-dimensional molecule with a specific 3D shape and chemical surface properties. The way biological catalysts work is by having one or more areas on their surface where target molecule(s) can attach. The molecules attach because the catalyst surface has the right kind of chemistry and shape for them to "fit" (by "fit", I mean the system has lower energy when together than when separate). Then, while bound to the catalyst, multiple things can happen to cause a chemical reaction -- such as other molecules attaching, or the catalyst acting on the target molecule, etc.

Heat Gain by Solar Radiation Versus Loss by Evaporation in Pool Heat Gain by Solar Radiation Versus Loss by Evaporation in Pool Name: Chris Status: student Grade: 9-12 Country: Spain Date: Winter 2011-2012 Question: We cover our pool with black EPE sheets of 20mm thickness to prevent heat loss and save energy. During the day, is it better to leave the pool covered during the day (preventing heat loss by evaporation) or to uncover the pool to allow max passive heating by solar radiation? In other words, is the heat gain by passive solar radiation on a sunny day enough to compensate for the heat loss by evaporation? Replies: Chris That sounds like an interesting experiment. And all you would need would be a thermometer. If your pool cover is black, my guess is that it would be best to keep the pool covered because the black cover will absorb all of the light energy that falls on it. However, there are so many variables in the experiment, like color of the cover, size of the pool, air temperature, etc. that it would probably be best if you run the little experiment yourself.

Ice Advantages Ice Advantages Name: Gloria Status: other Grade: 12+ Location: Outside U.S. Country: USA Date: N/A Question: What are some biological advantages of ice in reference to a lake, pond, or stream? Replies: Gloria One of the things I can think of is that some eggs and plant seeds need to experience a freeze before they will hatch or germinate. That is a genetic characteristic of their life-cycle. Some eggs or seeds may require a couple of freeze cycles before they hatch or germinate. The advantage to this is that it prevents pre-mature hatch/germination. For example, if we have an unusually warm day in January, the eggs or seeds won't hatch or germinate and then die in the middle of winter. We have all seen daffodil flowers rise early because of unusually warm January/February weather only to be frozen by a March cold spell.

Replies: Peggy A common misconception about cattle (particularly bulls) is that they are enraged by the color red (something provocative is often said to be "like a red flag to a bull"). This is incorrect, as cattle are red-green color-blind.[31][32] The myth arose from the use of red capes in the sport of bullfighting; in fact, two different capes are used.

Measuring Soot from Candle Measuring Soot from Candle Name: Cathy Status: student Grade: 9-12 Location: MD Country: USA Date: Winter 2011-2012 Question: How can you measure the amount of soot coming from a candle? Is there some kind of mathematical equation that can be used to determine this? Replies: Cathy, I am not aware of any mathematical equation that can predict the amount of soot formed. The problem is that soot is the result of an incomplete combustion of the candle. A complete combustion would produce CO2, H2O (and maybe a few other types of gases) and so there would not be any soot. Soot is mostly solid carbon (with a few other types of atoms mixed in) produced when these carbon do not react with the oxygen present. This means that the amount of soot would be dynamically controlled by the burning temperature, the amount of oxygen available at the reaction sites, the amount of heat being produced, etc. etc. ... very complex. It might be better simply to try to correlate the amount of soot (collected by scraping and weighing) to whatever variable you are interested in while trying to hold all other variables constant.

They've decided on the Luminol reaction with 3% hydrogen peroxide. I have always thought (perhaps incorrectly) that "thermic" is used when discussing heat energy - and there is very little heat change in this reaction. In the practice demo that the students did, the temperature dropped only about a degree C. However, there was a significant amount of light energy given off. When light energy is released, is that also considered exothermic? Or would it be more correct to call it an endothermic reaction (because the temp dropped), but also an exergonic reaction (because light was released)?

Communication Communication Name: Giovanni Status: other Grade: other Location: Outside U.S. Country: Italy Date: Summer 2011 Question: I have read that cats tend do communicate to each other more with body language (and other sounds: hissing, growling etc) rather than meowing. Again the two exceptions seem to be mother with kittens, and intact males at the intial phases of dominance "discussion". Now, I recently two neutered females (mother 2Y (M) and daughter (D) 10 months). A (very likely male & neutered)cat (X) has been visiting our garden; typically when he arrives and our cats are not out starts meowing (does not sound aggressive, nor his body language does); there have been a couple of initial apparently friendly (nose to nose) allbeit very prident contacts between M and X, but at the end f the sedon one M started growling and I and Dwent got closer and X run off. Since then though X has been coming back evry night and morning, again meowing (again does nt sound aggressive) but now M refuses to go out or stays very well clear of X when he arrived. D in all that is quite prudent but less concerned and X does not seem to have a problem with it at all, and they both roam the garden at the same time with no particular intereaction. Furhter info: M is a fairly big female Norwegian Forest cat (5.5kg), X ia a properly big (non descript)cat (must be 6.5+ kg...so unlikely to be a female), D is still quite small (for a NFC) at about 4kg) WOudl you have any idea for my description on what is going on, and how shoud I interpreter the meowing etc?

Water was placed in both a flask and beaker...just as a side experiment about the container shape. She placed the liquids in a room with an ambient temperature that fluctuated between 68-75 degrees Fahrenheit. Unfortunately, we did not measure the humidity (in reading the archives, it has a huge effect on evaporation). She turned on a work lamp for one hour a day for 10 days. The temperature in the room would get up to 98 degrees Fahrenheit.

Replies: Yes, but such an engine's maximum horsepower output is reduced in proportion to the pressure, typically. Jim Swenson Andy - It is definitely "possible", but almost never practical enough to be worth doing. The one real-life example I can think of is: the through-the-car-window antennas for cell-phones, GPS, etc. These have a cable from the transmitter box, carrying about 1-to-10 Watts of RF current, to a patch stuck to the inside of the window. At the same spot but on the outside face of the glass, is a similar patch which picks up the power radiated by the first patch, and a second length of cable running to a roof-top antenna. Notice that the wireless gap is only 0.5 cm, but the width of the patch is ~5 cm. Also, the freespace wavelength at that frequency is only 4-10 times the 5 cm size of the patch.

Gases Trapped in Filter Gases Trapped in Filter Name: Jay Status: student Grade: 9-12 Country: USA Date: Spring 2012 Question: Would the toxic gases that are trapped in a charcoal filter gas mask be an example of a mixture, solution, or something else? Replies: It certainly would be a mixture. Generally, the gases are considered to be "adsorbed:" the molecules cling to the outsides of the charcoal particles. Richard E. Barrans Jr., Ph.D., M.Ed. Department of Physics and Astronomy University of Wyoming That is an example of adsorbtion, (with a "D") which is a fairly common mode for mixtures of solid and gas. Adsorbtion can have bond strengths ranging from weak like of physical condensation (solids and liquids vs gasses) to almost as strong as a chemical bond within a molecule. It depends on the particular pair of adsorbing and adsorbed species. Because the solid's structure remains unchanged, the gas doesn't fully penetrate the solid, it just sticks on the surface. The mixture remains pretty heterogeneous on the microscopic scale: solid here, gas there. That is one reason why it is not considered a solution, even though the bonding energy there can be greater than that of most solutions.

Insect Gas Exchange Insect Gas Exchange Name: Mukuni Status: other Grade: 9-12 Location: Outside U.S. Country: Zambia Date: Winter 2011-2012 Question: How does the uptake of oxygen in insects increase during strenuous exercise? Replies: During strenuous activity, O2 demand in insects can increase two to tenfold. There are a few mechanisms that they can employ to ramp up O2 intake: 1) Insects can simply tolerate lower internal O2 and higher internal CO2. This increases partial pressure gradients and enhances gas exchanges by either diffusion or convection. 2) Insects can open their spiracles wider or for longer periods of time to increase gas exchange. 3) Insects can increase convective ventilation through the spiracles and tracheal system (or gills) through abdominal pumping or gill waving. 4) Insects can reduce fluid levels in the tracheoles to enhance O2 delivery within the tissues, since O2 diffuses faster in air than in water.

Free Falling Elevator and Floating Free Falling Elevator and Floating Name: Kevin B. Status: student Grade: 9-12 Location: CA Country: USA Date: Spring 2012 Question: I had a debate with my uncle about what would happen to a person in a free falling elevator. I asked him if the person would float. My uncle said no. He pointed out that a ball would not float if put on the floor of the elevator and the cable was cut, so why would a person? To see what would happen to a ball in a free falling elevator, I put a ball on a folder (the folder representing the floor of an elevator), and I dropped the folder with the ball. The ball stayed on top of the folder as they both fell to the ground. This indicated that what my uncle said about a ball staying on the floor of a free falling elevator was likely correct. However, when I researched the subject on the Internet, I came across many articles that said that a person would float in a free falling elevator. So I am a bit confused. Why would a person float but a ball would not? So my question is: 1) Would a person stand on the floor of a free falling elevator or would he float above the floor in a free falling elevator? 2) If the person would stand on the floor of a free falling elevator, please explain why. If the person would float above the floor, please explain why.

Source of Magnetic Force Source of Magnetic Force Name: Ashley Status: educator Grade: K-3 Location: AS Country: Australia Date: Spring 2012 Question: What makes magnets push and pull against each other? Replies: Hi Ashley, Magnets have an attraction and a repulsion force that we can see, measure and even use to better our living. We may also run experiments to see what it does and then use Science to explain what it does and how it behaves. It behaves so we may see attraction and repulsion; our fingertips can measure the strength of that. We run experiments that show electricity forces and magnetic forces are related. But what makes magnets do that? We really do not know what makes a magnet push and pull, it just does. The magnetic force, what is it? It just "is". To quote physicist Richard Feynmann, "I really can't do a good job, any job, of explaining magnetic force in terms of something else you're more familiar with, because I don't understand it in terms of anything else you're more familiar with."

Carbon-14 Nitrogen-14 Binding Energies Carbon-14 Nitrogen-14 Binding Energies Name: Abby Status: educator Grade: 9-12 Location: WI Country: USA Date: Spring 2012 Question: Carbon-14 decays into nitrogen-14 by beta emission. I have/had the understanding that when a nuclei decays the binding energy of the daughter is greater than the binding energy of the parent. From my research this does not seem to be true for carbon-14 into nitrogen-14. The binding energy per nucleon for carbon-14 is 7.520319 MeV and the binding energy per nucleon for nitrogen-14 is 7.475614 MeV. I understand that carbon-14 had too many neutrons and that it decays by beta because of this. I understand that nitrogen-14 is more stable than carbon-14 but if it is more stable than why isn't the binding energy of nitrogen-14 greater than that of carbon-14. Hope this all makes sense.

I mixed a ribbon of magnesium with white distilled vinegar and it turned a deep crimson after a few weeks. I never knew that it would do this, but I tried to add onto this by seeing if calcium carbonate (drawing chalk?) would affect the acidity or cause a reaction. I used a pen to stir it because it was the only thing I had to use, but I have noticed now after about two days, the pen is releasing a green cloud whenever I open it. The pen is a Zebra click pen and whenever I click it, a cloud of green dust or substance comes out. What is it? Why is the pen doing this?

Currently, our little caterpillars appear to be shedding chunks of their bodies. What is happening to them? Replies: The monarchs are molting. Since insects have exoskeletons (skeletons on the outside of the body) they must periodically "shed" to accommodate further growth. These shed exoskeletons are known as exuvia. Each stage in-between a molt is known as an instar. Try to have your students count the number of molts before the caterpillar undergoes metamorphosis.

Barn Pole Paradox Barn Pole Paradox Name: Kwanalouie Status: student Grade: 9-12 Location: TX Country: USA Date: Winter 2011-2012 Question: I do not see how this relativity problem is explained. Its a variation of the barn pole paradox. Can you offer insights? Replies: Kwanalouie, Einstein's special relativity theories apply to constant VELOCITY situations. This means no change of speed or direction. An observer on the ring is constantly changing direction. After half of a revolution, the observer's direction has exactly reversed. Length contraction is much more complex in such a situation. General relativity is needed for this situation. Dr. Ken Mellendorf Physics Instructor Illinois Central College You are mixing relative effects with non-relative effects to create the paradox. In creating what you think is a paradox, you are placing unrealistic constraints on the system (e.g. how do you decouple this massively energetic ring from the silo?).

Bacteria Resistance Bacteria Resistance Name: Brittany Status: student Grade: 6-8 Location: AZ Country: USA Date: Spring 2012 Question: Why have bacteria evolved resistance so rapidly? Replies: Suppose you have a bug spray and you use it to exterminate a cloud of mosquitoes. In the cloud of mosquitoes there may be one or two that are immune to the effects of the bug spray. So what you do is kill all the mosquitoes that don't have resistance to the bug spray Leaving behind the mosquitoes that do, and then those remaining mosquitoes regenerate. That is the sad story of how bugs develop resistance to our countermeasures. So far, we have always been able to find a bug spray formula to take care of the present cloud of mosquitoes.

Relativistic Velocity of Head-On Particles Relativistic Velocity of Head-On Particles Name: Flavian Status: student Grade: 9-12 Country: Romania Date: Spring 2012 Question: My question is about the LHC and any other particle accelerator, if the 2 matter beams travel at about 99% of the velocity of light relative to the ground in opposite directions don't they travel at 2x that relative to each other? What is actually going on? Replies: Flavian, How fast an object moves depends on the observer. When approaching the speed of light, the only reliable reference is you. Such velocities do not add like day-to-day velocities. Both distance and time measurements are different for those in different reference frames. The second matter beam might travel at a greater distance as seen by a particle in the first beam, but the time it takes to do it, as measured by the first beam, will also be greater. The distance divided by the time (i.e. speed) will be greater than 99% of light speed but less than 100%.

When it is placed on a mass balance, what would the reading be if the combined weight of the water and beaker is W, the weight of the object immersed is X and the upthrust that the object experiences is U? Replies: Jeremy, Whether hanging from the ceiling, immersed in the water, or whatever, the weight of the object will be the weight of the object. There is nothing special about it being in water, air or whatever. For your dilemma, we need to re-define the parameters. Let VO = Volume of the Object in cubic inches, feet, or whatever you wish to choose. WO = Weight of the Object in pounds WW = Weight of the water the VO displaces in pounds.

Earth Historic Rotation Rates Earth Historic Rotation Rates Name: Nikki Status: student Grade: 6-8 Location: AZ Country: USA Date: Spring 2012 Question: Did Earth ever spin faster than it does now? Did Earth ever have 18 hour days instead of 24 hours? Replies: Nikki, Earth rotates on its axis and continues to slow down because of tidal braking. Yes, it is the tides that result in the ever-slowing rotation of Earth. The main cause of the tides is the moon. That is, the ocean is constantly being pulled toward the moon while Earth rotates under this bulge of water. In order for the sun to be overhead at noon we add one second to the clock about every eighteen months. Yes, that is true, Earth's rotation slows by aboutone second every eighteen months. About 600,000,000 years ago, there were 420 days in one year! About 300,000,000 years ago there were 395 days in one year. Today, there are about 365.25 days per year.

Magnetic Reversal and Magnetic Strips Magnetic Reversal and Magnetic Strips Name: Mary Ellen Status: student Grade: 6-8 Location: NE Country: USA Date: N/A Question: My earth science teacher has been telling us about continental drift and magnetic striping in ocean rocks due to magnetic reversals. She said that by the pattern, this is due to happen again, soon. Will the strip on my bus card still work? Will magnets that now attract, repel (and the other way around? Replies: Mary Ellen, Magnetic reversals are not predictable. There is no pattern to the reversals. There is no evidence that this will occur any time soon. The last magnetic reversal occurred 730,000 years ago, so for the last 730,000 years the north end of the magnetic needle on your compass always pointed north. It takes about 1000 years for a reversal to occur, so, if you took a Rumpelstiltskin sleep, when you woke up, the north end of your compass needle would point south.

Meteor Soft Landing Meteor Soft Landing Name: Les Status: other Grade: 12+ Location: WA Country: USA Date: Winter 2011-2012 Question: Given the surface speed of the earth (daily rotation, yearly orbit, etc.) in relation to everything, is it possible for a meteor or asteroid at just the right path and speed to make a "soft" landing on the surface? Replies: Les I guess it is possible that a meteor or asteroid would have just the right course and speed to make a soft landing on Earth, but it is highly unlikely. Most meteors and asteroids travel and really high speeds. You see them burn in the atmosphere nightly and very brief streaks of light. Sincere regards, Mike Stewart Les, It would not be possible without risking burning up in the atmosphere. To make a soft landing, the meteor would also have to be able to make a soft launch. Barring energy loss to the atmosphere, energy conservation requires that such a landing work the same in both directions. Such a landing could be no slower than the speed needed to launch the meteor back to where it came from. With energy loss due to the atmosphere, slowing from this necessary speed to a soft landing would probably burn the meteor up. An Apollo spaceship landing without open parachutes is better than a meteor could do.

Many sources recommend lubricating the rubber bands - the main rationale for this is that they improve the elasticity of the rubber band and possibly reduces friction. I can see how reducing friction would be advantageous, but it seems to me that given a fixed number of winds, improving elasticity would reduce the actual kinetic energy of the motor. (I can see that improving elasticity may allow for a greater number of winds and >reduce the chance it breaks- but I am assuming the same number of winds.) Do you agree or disagree?

Internal Battery Resistance Change During Use Internal Battery Resistance Change During Use Name: Mikus Status: student Grade: 9-12 Country: Latvia Date: Spring 2012 Question: Does the internal resistance of a battery change if the battery is being discharged? Replies: Yes. Batteries play a lot of messy games with their internal resistance. The resistance can depend on temperature, percent-of-charge-remaining, recent history of current drain, and battery aging. Each kind of battery (lithium, alkaline, lead-acid, Ni-Cd, NiMH) has a different set of behaviors. I have seen a lithium battery, when suddenly asked to push a large load, allow its output voltage to drop a lot at first, because its internal resistance was high, because the battery was cold. Then the large current flowing through that internal resistance warmed up the battery, and the voltage delivered actually increased with time, for a little while.

Hydrogen Versus Deuterium Bonds Hydrogen Versus Deuterium Bonds Name: A. K. Status: student Grade: 9-12 Country: USA Date: Spring 2012 Question: If you have a compound, say HCl, why does the bond length decrease when you substitute the hydrogen atom with a deuterium atom? Replies: Hi A. K. Think of the bond in a diatomic molecule (H2 versus D2) as a spring between two spheres (the atoms). Let's say the available energy to make the spring vibrate is constant (you supply a specific amount of energy). The H2 spring will vibrate more because the masses being held by the spring is lighter than that of the D2 spring (remember that D is twice the mass of H). In effect the H2 system can extend farther away from the center than the D2 system. Since the closest approach of the H2 and D2 systems are the same (the same sized spheres touching each other) and the H2 system can get farther out than the D2, we can see that the average distance between the two H's is larger than that of the two D's.

There are two side of the discussion. Side A's rational is that density is hardly affected by humidity content and consequently so thus lift. The back-ground for this is the following: A) water molecular weight is lower than dry air molecular weight and consequently a mixture of both gases will have less density (for a given volume, at same pressure and temperature). B) Advogardo's Law - for any given gaseous mixture the number of particles is constant within a specific volume, if pressure and temperature being kept constant.

There is inexpensive software that can help by defragging registry files (not a task for the timid). The option that I was not aware of is deleting files in the "sent items" folder of Outlook Express. This is different than the "deleted items" folder, and at least on my computer was not showing the number of files contained in the "sent items" folder.

Male Development Male Development Name: Kurt Status: other Grade: other Location: Outside U.S. Country: Brazil Date: Spring 2012 Question: I heard that the male fetus has to go through stages to definitely become a male - that all fetuses are initially female, and that only after 8 weeks does the male fetus develop testicles, and that after that, I understand there are 3 more stages of development for the fetus to go through before definitely becoming male. What are these stages? Replies: Embryos are male or female from the moment of conception because they have either XX or XY chromosomes. But they don't start to develop their sexual phenotypes for about 6-8 weeks. Embryos have two nonspecific gonads and two sets of nonspecific tubes. If there is a Y chromosome, a gene called SRY turns on around 6-8 weeks and starts male development. The nonspecific gonads become testes and the tubes become the vas deferens. It causes the second set of tubes to degenerate. It also causes the testes to begin secreting testosterone which also adds to the masculine phenotype. There is a step by step process that happens. If there is a block in the process everything stops there. So some parts could develop and others not.For instance, internal structures might develop but external not. This would result in an ambiguous phenotype which may be mistaken for a female.

A lens can be removed from the eye, but typically a lens cannot be cleared. The changes to the internal structure of the lens are permanent, thus making it cloudy. A new, artificial lens could be put in if there was one the right size for a cow eye, just like in human cataract surgery. There are other conditions that can cause cloudiness of the eye, but that usually involves the fluid in the front of the lens. These conditions can sometimes be treated medically.

We really can't say how the animal itself feels, they are enough different from us that we can't know exactly how their brains sense their environment, especially in hibernation which is not like anything humans experience.

Replies: The example you describe is pure coincidence -- not genetic. The environment does impact our genes, and those genes can be passed on to our children. However, the changed gene has to be in the gamete (sperm or egg) -- these cells alone contain the genetic material that is passed along. A change to a finger (that has not also occurred in the gamete) would not be passed on.

Replies: Sorry Chris, it is the other way around. If you are near lightening you hear a crack or bang which is a high frequency sound. But far away from the lightening you hear thunder as a low pitch, rolling, boom. The high frequency sound from the crack you hear close up does not made it very far from the lightening (which is the cause of the noise). Hope this helps. R. W. "Mr. A." Avakian Quite the opposite. Low pitched sounds attenuate more slowly with distance. Fog-horns are an evolutionary example of the point. Of course, they are meant to operate in elevated humidity, which adds another loss factor. I will try to tell you more later. On the other hand, it is quite possible for high-pitched sounds to be _more_noticeable_ to a given being in a given noise background.

Thus, the osmotic pressure against the inside of the plasma membrane may be the equivalent of 10-25 atmospheres. Since the membrane is a delicate, plastic structure, it must be restrained by an outside wall made of porous, rigid material that has high tensile strength. Such a material is murein, the ubiquitous component of bacterial cell walls."

Vince Calder Ph.D. Vince Calder Ph.D. I am a retired physical chemist [1965, Berkeley with W.F. Giauque] with a broad background in many areas of chemistry/physics: thermodynamics, I.R. spectroscopy, polymer chemsitry, analysis of ground water for trace organic compounds. My hobbies include photography and mathematics. How can I participate in your program. I have taught [Iowa State] and have an interest in fostering interest in science to young people. Consultant in landfill remediation, and prevention of landfill contamination. The best landfill remediation is preventation before it happens. This is a complex issue because it brings to the front that the "science" is not enough. There are social and political issues that have a direct impact on the "science". It isn't good enough to have good science if nobody is listening. This requires acquisition of a whole bunch of skills that we don't teach in the classroom.

Red Shift and Expanding Universe Red Shift and Expanding Universe Name: Ivan Status: other Grade: other Location: FL Country: USA Date: Fall 2011 Question: It is about red shift and the outer galaxies. I do have a grasp of the concept of expansion. What I do not understand is and it bothers me: It is said that the outer galaxies of our observable universe are expanding between them faster than closer ones. First I am correct in saying that? Second, if I interpreted what I read correctly, would an observer at the edge of our observable universe, looking towards our galaxy see the opposing situation: an observable universe that is reducing in expansion, with that other observer's outer galaxies progressively expanding less (as this would be the galaxies closer to us)? Replies: Hi Ivan -- If you were in that far-away galaxy, you would make the same observation about galaxies near the milky way: that the farther-away galaxies are moving away from you faster than galaxies closer to you.

Reducing Data, Increasing File Size Reducing Data, Increasing File Size Name: Jim B. Status: Other Age: 60s Location: N/A Date: 8/4/2004 Question: For backup purposes I am trying to reduce the quantity of the data to back up. I am running a WIN 2000 pro system. I had about 13K files, some with large attachments, in my Outlook Express Inbox.DBF and Sent Items.DBF files. They totaled about 2.8GB worth of data. I deleted most of the files (out of the Deleted Items area as well). The size of the 2 aforementioned DBX files actually increased slightly. I did not expect that. The result is that my backup problems are exacerbated. What is up? Replies: Truthfully, I do not know that much about Outlook Express. This site is a help site for users at the University of Delaware. Most of it is not very helpful, but it talks about "Purging deleted messages". It may be that the emails are still in the deleted folder. It is worth a shot. Sorry I couldn't be more help and I hope I did not misunderstand.

White Blood Cells Oxygen Source White Blood Cells Oxygen Source Name: Meg Status: student Grade: 6-8 Location: KY Country: USA Date: Winter 2011-2012 Question: All cells need oxygen. That is a common fact. So then where do white blood cells get theirs? Replies: The oxygen for white blood cells comes from the blood, just as it does for other tissues. Oxygen is transported from the lungs to red blood cells, and as the red blood cells move through the blood, they supply the white blood cells with oxygen. br> Diffusion is the primary mechanism that drives this oxygen transport -- as the white blood cell converts O2 to CO2, it establishes a concentration gradient between the blood (high O2) and the interior of the white blood cell (low O2). This concentration gradient drives oxygent transport.

December 10 - December 17 Question of the Week Name: Millard Status: student Grade: 9-12 Location: MD Country: USA Date: Spring 2013 Question My dad has a classic car, and because it gets driven very little each year, the tires dry rot before he can get much tread wear on them. What could be used to protect the tires from dry rot and cracking? Answers from Our Expert Staff Hi Millard, Thanks for the question. I would recommend keeping the car on blocks so that there is no weight on the tires. Additionally, I would recommend that no electrical equipment (motors, switches, and other things that spark) be used around the car. The sparks generate ozone and ozone can cause rubber items such as tires, belts, and hoses to crack. I hope this helps. Please let me know if you have more questions.

Longest Day in Tropics Longest Day in Tropics Name: Owen Status: other Grade: other Country: Australia Date: Spring 2012 Question: I have checked the archive and it is not really answered there. http://www.newton.dep.anl.gov/askasci/gen01/gen01052.htm isthe closest link but does not really get to the crux of what I amasking below. Is the solstice still the longest day (in either hemisphere) if your location is between the Tropics? Some friends and I have been debating this. One faction argues that the solstice on 21 December is the longest day here in Cairns, QLD, Australia. the other faction claims that the longest days here are when the sun is directly overhead (we believe the days to be 28 November and 12 January here in Cairns) and that the days shorten between 28 November (zenith in CNS) and 21 December (solstice) ... then graduate/lengthen back to the maximum between 22 December until 12 January (our other zenith day as the sun moves back North) ... after which, they shorten again. can you please settle the debate (with an explanation).

Energy in a System Energy in a System Name: Michael Status: educator Grade: 9-12 Country: USA Date: Spring 2012 Question: I am a high school chemistry teacher with a quick question about entropy, which may be only one of semantics - I am hoping you might be able to help. . I think the problem boils down to if we consider all the energy in a system (E=mc2), can all that be turned into work? The details are this: In discussing entropy, the isothermal, free expansion of a gas into a vacuum is an often used example (q=0,w=0). After the gas has expanded numerous texts and web sites (an MIT web site in this case) explains that " some ability to do work has been lost" and that "the property that is used to measure the change in ability to get work out of a system (delta)T is the entropy."

Video Game Programming Software Video Game Programming Software Name: John P. Status: Student Age: 14 Location: N/A Date: 8/4/2004 Question: My cousin and I are rabid video gamers. We want to be video game designers when we grow up, or do something along the lines of that. We want to start making game snow to start to get experience for when we grow up. Now we do not want to make 3-D or anything like that at our age now, what we want to do is make video games about the equivalent of stuff made on the Apple II and Atari, even the NES would be a good example of the games we want to make. I was watching a show on TV and the person was saying how many of today's greats were just teenagers programming stuff on a Apple II. I figure since they started there at my age I should try to start there too. I wanted to know if there was any programs available to make these types of games, because if they could do it 20 years ago on with the limited technology they had, then I should be able to do it faster, easier, and better then they did with today's technological advances.
