  5. Comparative analysis of Nigerian international oil marketing model (NIOMM) and the models of four selected OPEC members; and a proposed new model for Nigeria

    SciTech Connect (OSTI)

    Udeke, O.O.


    This study demonstrates that NIOMM has deficiencies and, as a result, has affected the progress of Nigeria's political and socio-economic development. One finding is that Nigeria is beset with ineffective planning, lack of marketing expertise, and inadequate marketing strategies. Other findings show that: (1) the Nigerian oil industry (HOI) is suffering from mismanagement stemming from corruption, tribalism, Federal Character Policy, and lack of dedication and patriotism by the Nigerian workers; (2) there is inefficiency in the Nigerian national petroleum corporation (NNPC) but, at the same time, the inefficiency is partly because of the government policies, conflicts, interference by high government officials and politicians, and the enormous size of the oil industry; (3) oil revenues are improperly utilized; (4) neither the multinational oil corporations (MNOCs) nor multinational corporations (MNCs) are assisting the oil producing nations (OPNs) or developing countries (DCs) in their economic development, and MNOCs and MNCs are interested in profit maximization; and (5) MNCs do not transfer the type of technology that meets the needs of DCs, and sometimes the technology creates problems for DCs which ultimately results into conflicts between MNCs and DCs. The inverse of these problems has been a sine qua non for success in the IOMMs of the four OPEC member, especially in Saudi Arabia.

    Obuasi, P.A.


    This article discusses the growth patterns of the Nigerian refining industry. Production and consumption are expected to follow the pattern of consumption of fuel products by the domestic market, Presently, however, production and consumption are not evenly balanced for most fuel products, and non-fuel products are domestically consumed but not produced. Some progress has been made in the effort to match production and consumption of fuel products. But the progress that would have been made to balance non-fuel products has been nullified by 50% of the Daduna refinery being idle. This is due to problems associated with importation of heavy crude oil into Nigeria and also a weak market for asphalt in Nigeria.

    In this paper, the results of a study on the effect of oxidation on the {Delta}P index and acidity of three Nigerian coals are reported. The coals are oxidized in air over a period of 35 days at both 100 and 50{degrees} C. The heating value, slurry pH (acidity), and the {Delta}P index of three Nigerian coal samples were monitored as a function of oxidation time. The results revealed a decrease in {Delta}P index and an increase in the acidity of all three coals with increase in oxidation time. The heating value of the coals was also reduced by the oxidation.

  10. Tolerance of nitrobacter to toxicity of some Nigerian crude oils

    SciTech Connect (OSTI)

    Okpokwasili, G.C.; Odokuma, L.O. (Univ. of Port Harcourt (Nigeria))


    Crude oil spillage in aquatic systems affects thousands of aquatic species including bacteria. Some of the crude oil components are rapidly evaporated or biologically degraded. Other components continue to remain for several months and perhaps several years. Some of these components may be toxic to microorganisms, while some may stimulate microbial activity especially at low concentrations. The use of bacteria as bioassay organisms is now gaining wide acceptance. It offers a number of advantages such as ease of handling, economy of space, short life cycles and low cost. Their uses in bioassays are based on cell lysis, mutagenic properties and the inhibition of physiological processes such as respiration. Recently, a number of workers have proposed the use of Nitrobacter as a test organism. The organism has a number of advantages in toxicity testing: obligate autotrophy, its sensitivity to various toxicants and its predominance in wastewater environments are some of them . Of recent, the inhibition of bacterial enzyme biosynthesis have been suggested in bacterial assays. The objective of this study was to determine the effects of six Nigerian crude oils on the cell reproduction rate (LC, lethal concentration), cellular respiration (EC, effective concentration) and biosynthesis of enzyme responsible for nitrite oxidation (IC, inhibition concentration) in Nitrobacter. In addition, the goal was to identify which of these was the most sensitive to crude oil and which may thus be used for detecting the toxicity of these chemicals. 18 refs., 2 figs., 1 tab.

  11. Adjusting flow station job to remote Nigerian location yields savings

    Wooten, R.; Williams, E.C. (OPI International Inc., Houston, TX (United States))


    In September 1991, Chevron Nigeria Ltd. and Nigerian National Petroleum Crop. contracted Offshore Pipelines to design, procure, construct, install, and commission the Opuekeba 30,000 b/d crude-oil flow station on an offshore platform near Olero Creek, Nigeria, approximately 22 miles from the nearest deepwater access. Chevron's original project plan included bringing the flow station to the site in small packages and then assembling it in a lengthy field hook-up process. Offshore Pipelines developed a plan early in the project to maximize construction and hook-up in the fabrication yard, then transport the nearly complete structures to site by way of a newly dredged canal. What proved to be most difficult was the site location in Nigeria. Job planning and communication were important in the successful completion of the project. Keeping the components of the large and complex facility simple proved to be effective and efficient and played a key role in completing the project on time and within budget. The paper discusses overcoming obstacles, lift and depth constraints, dredging, fabrication, installation, and large-time problems.

  12. Natural resource booms and Third World development: Assessing the subsectoral impacts of the Nigerian petroleum boom on agricultural export performance

    SciTech Connect (OSTI)

    Banks, S.M.


    Linear and quadratic expansion model formulations are developed to assess the relative complexity of booming-non-booming sector interactions. Specific attention is given to the extent to which the growth rates of Nigerian agricultural exports have changed over time as: (a) the volume of oil exports, and (b) the growth rate of oil exports are allowed to vary over a set of hypothetical values which reflect Nigerian oil-boom realities. Four important conclusions emerge: (a) the quadratic expansion model most accurately captures Nigerian oil-agricultural exports are most clearly influenced by the oil boom; (c) the growth rate of capital-intensive agricultural exports are initially stimulated, and later stagnated by the oil boom, while the growth rate of subsidized labor intensive agricultural exports are first stagnated and then stimulated by the oil boom; and (d) the expansion method provides a useful alternative means of exploring theoretical and applied issues related to the Dutch Disease paradigm. the implications of the findings for agricultural and petroleum policy in Nigeria are assessed, and a research agenda for further booming-non-booming sector investigations is proposed.

  14. Impact of 3-D seismic data on the Nigerian National Petroleum Corporation/Chevron Nigeria Limited joint venture development drilling program

    SciTech Connect (OSTI)

    Quam, S. (Chevron Nigeria Ltd., Lagos (Nigeria))


    The Nigerian National Petroleum Corporation/Chevron Nigeria Limited joint venture has been acquiring three-dimensional (3-D) seismic data over its concessions since 1984. To date, 1700 km[sup 2] have been recorded and processed at a cumulative cost of US $39 million. During 1991 - 1992, 20 development wells were drilled based directly on new 3-D seismic interpretations. These wells have added 148 million bbl of oil in new recoverable reserves, and to date have added 37,000 bbl/day to the joint venture's production. In addition, the 3-D interpretations have resulted in a sizable inventory of wells for future development drilling. The new 3-D interpretations provided more accurate pictures of fault patterns, fluid contacts, channel trends, stratigraphic continuity, and velocity/amplitude anomalies. In addition, the 3-D data were invaluable in designing low risk, directional well trajectories to tap relatively thin oil legs under large gas caps. Wells often were programmed to hit several objectives at their respective gas/oil contacts, resulting in maximized net oil sand pays and reducing the risk of gas production. In order to do this, directional [open quotes]sharpshooting,[close quotes] accurate depth conversion of the seismic time maps, was critical. By using the 3-D seismic, checkshot, and sonic data to develop a variable velocity space, well-top prognoses within 50 ft at depths of 6,000-10,000 ft were possible, and were key to the success of the program. As the joint venture acreage becomes more mature, development wells will be drilled for smaller numbers of stacked objectives, and sometimes for single sands. Highly accurate 3-D interpretations and depth conversions will become even more critical in order to tap thinner pay zones in a cost-effect manner.

  16. Enigmatic compressional structures in an extensional province: Eku field, OML 67, offshore Nigeria

    SciTech Connect (OSTI)

    Quinones, M.; Evans, R. (Mobil Technology Co., Dallas, TX (United States)); Alofe, K.; Onyeise, B. (Mobil Producing Nigeria, Lagos (Nigeria))


    Acquisition of 3-D seismic data over OML 67-70 and a detailed reservoir description study done on the Eku field, have allowed identification of previously unrecognized compressional features. Situated within a depocenter between arcuate normal growth faults, the Eku structure consists of a shale-cored anticlinal fold and fold-and-thrust separated by a zone of lateral displacement. The crests of the folds have been eroded at a major unconformity at the base of the Qua Iboe shale (Early Pliocene). In the absence of definitive biostratigraphic data, correlations among the various fault-blocks are based on the character of sedimentary packages and sequences on wireline logs. Combined with analysis of the geometry of faults and folds, the correlations support a description of pulsatory movement of folding and faulting, that ultimately culminated in extensional reactivation of earlier regional extension and the not coincident. The effect of the anticipated reservoir sections, and deformation, both compressional, was gravity-driven and on shale detachments. A working hypothesis to explain the disparity in direction of earlier extension and subsequent compression is that thermal expansion that accompanied formation of the Cameroon volcanic line to the east of the Niger Delta in Miocene time, caused a change in the direction of structuring, allowing downslope gravity-driven compression to be superimposed on pre-existing extensional features.

    Nigeria's campaign to increase foreign investment in its petroleum industry and boost oil and gas productive capacity continues to gather steam. Critical to that effort is a continuing push by the government to offer more attractive fiscal and concession terms to private domestic and foreign companies. Nigeria's petroleum ministry has submitted a new draft petroleum policy for government approval. The campaign is getting results, if responses by key foreign operators are any indication. This paper reports that the changing investment climate in Nigeria is attracting more outside financing.

  8. Toxicity of corexit 9527 and Nigerian crude oil in vivo and in vitro

    SciTech Connect (OSTI)

    George, S.; Nelson, G.; Brooks, L. [Environmental Protection Agency, Research Triangle Park, NC (United States)] [and others


    When oil is spilled into aquatic systems, chemical dispersants frequently are applied to enhance emulsification and biological availability. In this study, toxicity of Corexit 9527 (Cx), a widely used dispersant, was evaluated with oil both in vivo and in vitro. Initially, both Cx and oil were bioassayed in a micro-suspension modification of the Salmonella reversion bioassay. Next, rats were dosed 5 weeks with oil, Cx or Cx/oil. Body and tissue weights, urine mutagenicity, and effect on intestinal enzymes and microbiota were determined. Cx (1:1000 dilution) was toxic in the bioassay and oil was negative (TA98 & TA100 +/-S9). Similar results were observed for urinary metabolites. Body and tissue weights were unaffected, but a significant reduction in small intestinal azo reductase (AR) and/or {beta}-glucuronidase (BG) was observed in animals that received Cx, oil, or Cx/oil. Effects on cecal AR were observed in the 3 treatment groups. One week nitroreductase (NR) activity was elevated, and 3 and 5 week BG activities were significantly different from controls. This correspond to an elimination of enterobacteria and enterococci in oil-treated rats and enterobacteria fluctuations in Cx- and Cx/oil-treated animals. Even though treatment of rats with Cx has no direct effect on the production of mutagenic urine metabolites from oil-treated animals, significant changes are observed in intestinal microbiota and their enzymes responsible for promutagen and procarcinogen activation.

    Kalu, T.Ch.U. [Univ. of Ilorin (Nigeria)


    Most empirical studies have focused on the demand side of energy with little or no attention to the supply side. To deal with this defect, this paper adopts a microanalytic approach to the problem of the individual oil firms to provide a basis for determining the effects of changes in such macro-variables as prices on their operations. However, instead of the familiar econometric approach to energy studies, a goal programming approach is adopted. Using a multinational oil company as a case study, the effects of change in crude oil prices are examined. The results, among other things, support the hypersensitivity of oil companies to changes in economic cycles, the price inelasticity of demand for crude oil in the short run, and a time lag between price change and the time an oil company responds to it. The management and policy implications of the results are also discussed. 28 refs., 3 tabs.

  13. From oil shortage to oil glut: simulation of growth prospects in the Nigerian economy

    SciTech Connect (OSTI)

    Olofin, S.; Iyaniwura, J.O.


    During the 1970s, the economy of Nigeria provided one of the most interesting cases of development financed through oil revenue. Between 1970 and 1980, the country's GNP grew at an outstanding rate, but after the transition from oil shortage to oil glut, the economy of Nigeria ran into dramatic financial difficulties, which are now placing major constraints to its development. To investigate the transition from an oil-based economy to a stage characterized by greater diversification of exports and more balanced sectoral growth, a model has been built by the University of Ibadan in Nigeria. The model was developed in association with Project LINK staffing for the future inclusion in the Project. According to the finding presented in the study, the annual growth rate of GDP of Nigeria between 1980 and 1988 will be around 2.5%. To compensate the drop of the foreign-exchange earnings caused by the contraction of oil prices and demand, a vigorous export drive of agricultural products is simulated. 8 references, 7 figures, 4 tables.

    The pulmonary function and symptoms of 125 workers exposed to carbon black in dry cell battery and tire manufacturing plants were investigated. There was no significant difference in the pulmonary function of the subjects in the two plants. There was good agreement in the symptoms reported in the two different factories: cough with phlegm production, tiredness, chest pain, catarrh, headache, and skin irritation. The symptoms also corroborate those reported in the few studies on the pulmonary effects of carbon black. The suspended particulate levels in the dry cell battery plant ranged from 25 to 34 mg/m/sup 3/ and the subjects with the highest probable exposure level had the most impaired pulmonary function. The pulmonary function of the exposed subjects was significantly lower than that of a control, nonindustrially exposed population. The drop in the lung function from the expected value per year of age was relatively constant for all the study subgroups but the drop per year of duration of employment was more severe in the earlier years of employment. This study has underscored the need for occupational health regulations in the industries of developing countries.

  18. Macro-econometric model of the Nigerian economy: a simulated analysis of oil shocks in a development context

    SciTech Connect (OSTI)

    Usip, E.E.E.


    The precarious position of Nigeria in being a one-resource (oil) based economy in terms of revenue generation has become a major cause of concern for the experts and political pundits. In this study, the author seeks to explore further the empirical basis for this concern in two stages. First, a macro-econometric model of Nigeria was constructed and evaluated. The model highlights the various channels through which the oil sector influences the rest of the economy. Economic theory, econometric techniques, existing fund of knowledge in the practice, computer simulation, and the institutional framework of Nigeria were brought to bear upon the modeling process. In the second stage, the resulting simulation model was used to examine the sensitivity of the economy to the leading sector (oil) as well as the growth potential of Nigeria up to 1986. The crucial question that was addressed is: will the oil sector be able to support a continuing economic growth of Nigeria in the absence of policy initiatives to diversify the revenue base of the economy. Although the empirical findings are hypothetical, they do have far-reaching implications for Nigeria's growth prospects and political stability.

  20. A Rubber-Modified Thermoplastic where the Morphology Produced by Phase-Separation Induced by Polymerization Disappears at High Conversions

    E-Print Network [OSTI]

    E. R. Soule; G. E. Elicabe; R. J. J. Williams


    An unexpected experimental finding is reported where the primary morphology developed during polymerization-induced phase separation in a rubber-modified thermoplastic disappears at high conversions. This process was evidenced by light scattering (LS) and scanning electron microscopy (SEM) for a particular composition of solutions of polyisobutylene oligomers (PIB) in isobornylmethacrylate (IBoMA), during the free-radical polymerization of the monomer. The primary phase separation produced a dispersion of domains rich in PIB containing significant amounts of the monomer (IBoMA). Polymerization of the monomer in these domains occurred at high overall conversions producing the filling of dispersed domains with a PIBoMA-PIB blend. Under these conditions the final material had the appearance of a homogeneous blend. The process might be adapted to produce new types of rubber-modified thermoplastics where rubber particles are replaced by rubber-rich domains that do not exhibit definite boundaries. Keywords:

    This study is concerned with the policies adopted by Brazil and Nigeria to promote the transfer and development of technology in industry. The objectives are two-fold: (1) to compare and analyze the policies with respect to the automobile industries in the 1967-1980 period; (2) to investigate whether their adoption was solely a function of the different ideological values and issue levels of economic development of the countries, or whether the regimes are solely an expression of the patterns of that development. The study adopted the Comparative Public Policy approach to explore the various hypotheses formulated. The findings showed that Brazil realized more significant results than Nigeria in technology development, while in other areas, such as the curtailment of imports, employment generation, etc., the results are mixed. The study concludes that both regime and industrial development factors influence the variation in the policies, although the regime factor seems to explain more of the variation.

  18. Use of Quantitative Uncertainty Analysis to Support M&VDecisions in ESPCs

    SciTech Connect (OSTI)

    Mathew, Paul A.; Koehling, Erick; Kumar, Satish


    Measurement and Verification (M&V) is a critical elementof an Energy Savings Performance Contract (ESPC) - without M&V, thereisno way to confirm that the projected savings in an ESPC are in factbeing realized. For any given energy conservation measure in an ESPC,there are usually several M&V choices, which will vary in terms ofmeasurement uncertainty, cost, and technical feasibility. Typically,M&V decisions are made almost solely based on engineering judgmentand experience, with little, if any, quantitative uncertainty analysis(QUA). This paper describes the results of a pilot project initiated bythe Department of Energy s Federal Energy Management Program to explorethe use of Monte-Carlo simulation to assess savings uncertainty andthereby augment the M&V decision-making process in ESPCs. The intentwas to use QUA selectively in combination with heuristic knowledge, inorder to obtain quantitative estimates of the savings uncertainty withoutthe burden of a comprehensive "bottoms-up" QUA. This approach was used toanalyze the savings uncertainty in an ESPC for a large federal agency.The QUA was seamlessly integrated into the ESPC development process andthe incremental effort was relatively small with user-friendly tools thatare commercially available. As the case study illustrates, in some casesthe QUA simply confirms intuitive or qualitative information, while inother cases, it provides insight that suggests revisiting the M&Vplan. The case study also showed that M&V decisions should beinformed by the portfolio risk diversification. By providing quantitativeuncertainty information, QUA can effectively augment the M&Vdecision-making process as well as the overall ESPC financialanalysis.

    This paper reports that within the past 18 months, the Nigerian Ministry of Petroleum Resources has moved aggressively to increase investment in known producing areas and stimulate exploration in frontier regions in order to define and expand the country's reserve base for the start of the 21st century. At industry seminars held in November and December 1991 in Houston, London, and Lagos, the Ministry in association with TGSI-Mabon Geophysical Co. reviewed the Nigerian political and economic climate, recent industry development and leasing activity, deep-water geology and exploration potential, and the probable areas' terms and conditions for a new bidding round to be announced in early 1992.

    QuaLiKiz, a model based on a local gyrokinetic eigenvalue solver is expanded to include momentum flux modeling in addition to heat and particle fluxes. Essential for accurate momentum flux predictions, the parallel asymmetrization of the eigenfunctions is successfully recovered by an analytical fluid model. This is tested against self-consistent gyrokinetic calculations and allows for a correct prediction of the ExB shear impact on the saturated potential amplitude by means of a mixing length rule. Hence, the effect of the ExB shear is recovered on all the transport channels including the induced residual stress. Including these additions, QuaLiKiz remains ~10 000 faster than non-linear gyrokinetic codes allowing for comparisons with experiments without resorting to high performance computing. The example is given of momentum pinch calculations in NBI modulation experiments.

  13. Nigeria to step up tar sands activity

    SciTech Connect (OSTI)

    Not Available


    The Nigerian government has directed its Ministry of Mines, Power and Steel to assume responsibility for the exploration and exploitation of tar sands deposits in Bendel, Ondo and Oyo States. The directive resulted from a survey report by the University of Ife's geological consultancy unit on bituminous sand deposits in the area. The statement said the government was satisfied that there were large commercial quantities of the sands in the three states. The survey had reported that Nigeria could recover between 31 and 40 billion barrels of heavy crude from the tar sand deposits. Exploration for hydrocarbons is currently going on in Anambra and Lake Chad basins as well as the Benue Trough. Apart from the Nigerian National Petroleum Corporation, Shell Petroleum and Gulf Oil have begun exploration activities in the Ondo area. Meanwhile, Nigeria has had to import heavy crude from Venezuela, for processing at the Kaduna refinery.

    Development of Nigerian massive reserves of crude bitumen and associated heavy oil is imminent in view of the impacts that the huge importation of these materials and their products have on the nation's economy, coupled with the depleting reserves of Nigeria and highlights the appropriate production technology options and their environmental implications. The utilization potentials of these resources are also enumerated, as well as the government's role in achieving accelerated, long-term tar sands development in the country.

  15. Public budgeting, public policy, and the politics of resource allocation in Nigeria

    SciTech Connect (OSTI)

    Ugorji, E.C.


    The problem of determining who gets what in terms of allocating the nation's resources has plagued Nigerian leaders since independence. It is in this context that this dissertation is focused on the politics of the federal governments's use of the budget as an effective mechanism for mobilizing and constructively utilizing the nation's human and material resources to improve the general well-being of all segments of the Nigerian society. This study was conducted through direct interviews and discussions with some federal government officials and some Nigerian scholars concerned about the problems of development in Nigeria. From the findings, it is concluded that the federal budget process has not functioned efficiently and effectively as a vehicle for moving the nation forward in the direction of sustained and balanced economic progress. Whereas the above situation can be attributed to some structural deficiencies in the budgetary process, it can also be argued that bribery and corruption, fraud and misuse of public funds by politicians and top government officials, be they civilians or military, have undermined all efforts at using the budget as an instrument for accomplishing development objectives.

    SciTech Connect (OSTI)

    Bachrach, E.R.


    This thesis explores the relationship between the oil-boom of the 1970s and development outcomes and the prospects in two African OPEC states. The theoretical framework is provided by the political-economy literatures, both domestic and international. The research is carried out as a limited comparative study with a loosely constructed (before-during-after) interrupted time-series design. Algeria's greater success in managing it soil economy suggests further evidence supporting the promise of a mixed political-economy state model. State and societal complexions are identified, with a primarily qualitative methodology, to explain Nigerian and Algerian development outcomes on the heels of the oil decade.

  5. Petroleum and structural change in a developing society: the case of Nigeria

    SciTech Connect (OSTI)

    Olayiwola, P.O.


    This study of Nigeria provides a multidimensional analysis of development. The Nigerian development experience is considered as the interrelation of: (a) economic development paradigm which guided development thinking; (b) the national planning model and apparatus employed; (c) the ideology of nationalism; and (d) the internal and external factors in Nigeria's environment that combined to influence its development strategies. As a society, Nigeria has undergone profound changes over the period of the last 25 years. It was transformed from a primarily agricultural society to an industrializing one. A key source of this change has been the emergence of the petroleum economy. Nigeria's GDP grew an extraordinary 81% per annum on average between 1960 and 1980. Yet, the aggregate performance of the petroleum economy was far better, adding to Nigerian economic wealth at an average rate of 7400% per annum. Judged on these terms, Nigeria's overall economic performance from independence to 1980 was spectacular; the performance of its petroleum economy astounding. Despite this performance, the structure of Nigeria's political economy is nearly the same as it was at independence. It remains one in which economic life depends critically upon world-market conditions and the level of trade with developed economies.

    We introduce the pyunicorn (Pythonic unified complex network and recurrence analysis toolbox) open source software package for applying and combining modern methods of data analysis and modeling from complex network theory and nonlinear time series analysis. pyunicorn is a fully object-oriented and easily parallelizable package written in the language Python. It allows for the construction of functional networks such as climate networks in climatology or functional brain networks in neuroscience representing the structure of statistical interrelationships in large data sets of time series and, subsequently, investigating this structure using advanced methods of complex network theory such as measures and models for spatial networks, networks of interacting networks, node-weighted statistics or network surrogates. Additionally, pyunicorn provides insights into the nonlinear dynamics of complex systems as recorded in uni- and multivariate time series from a non-traditional perspective by means of recurrence qua...

    Nigeria, a major oil producer, is rich in other energy sources. These include wood, coal, gas, tar sands, and hydro power. Although oil has been the most popular, some other energy sources have a longer history. This article discusses the historical trends in the production and utilization of Nigerian energy sources. Wood has the longest history. However,its utilization was limited to domestic cooking. Imported coal was first used in 1896, but it was not discovered in Nigeria until 1909 and was first produced in 1916. Although oil exploration started in 1901, it was first discovered in commercial quantity in 1956 and produced in 1958. Oil thereafter took over the energy scene from coal until 1969, when hydro energy was first produced. Energy consumption has been mainly from hydro. Tar sands account for about 55% of total proven non-renewable reserves.

    A survey of projects in research institutions and major public energy organizations was undertaken with a view to determining to what extent energy research activities are in consonance with national research objectives. Such a survey is also useful in developing an appropriate energy research policy for Nigeria. It appears that energy R and D efforts are concentrated in the area of alternative energy resources; this accounts for 66% of the total projects. Most of the local efforts are duplication of international research efforts. Even though the demand for energy research is well defined, the absence of proper coordination and adequate policy instruments have resulted in the unattainment of the research goals of the energy sector. Thus, the arguement adduced by some investigators that lack of demand for research is the main obstacle for designing and implementing a relevant science policy in a developing country does not hold for Nigerian conditions.

    The Asejire dam at Ibadan, Nigeria was constructed in the late sixties for the purpose of providing water for the city of Ibadan (presently about 4,5 million inhabitants). It is located on the Oshun river approximately fifteen miles from the city. In 1982 cracks were observed on the wing walls and although these continued to develop, no attempt was made at that time to investigate their causes and no repair was carried out. In 1989 the SGI ENGINEERING Group of Geneva, Switzerland was appointed as the consultant for the complete refurbishment of the Asejire water scheme. The consortium Degremont-Poat-Clemessy was awarded the contract for the project. The African Development Bank and the Nigerian Government have provided the loan to finance the project.

  15. Biotechnology research in Nigeria: A socio-economic analysis of the organication of agricultural research system's response to biotechnology

    Duru, G.C.


    Many agricultural development experts and social scientists argue that a lack of appropriate technology was a limiting factor in the efforts by developing countries to expand their agricultural productivity. Biotechnology is now advanced as a technology that could meet these needs. Agricultural and social scientists maintain that the new biotechnology, if realistically applied, could assist a developing nation such as Nigeria to solve its agricultural problems. But one concern is the private character of biotechnology which limits its transferability to the LDCs. This situation will impose unusual constraints on national agricultural development programs and increase dependence if national research capability is weak. The basic finding of this field research was that the Nigerian national agricultural research system was weak, which meant that the potentials and promises of biotechnology will elude the country's desire to improve its agriculture in the immediate future. The primary weakness rested in inadequate funding and infrastructural deficiencies.

    The Oyo-1 well was drilled in 3Q95 in OPL 210. The partners in the block are Allied Energy (Operator) and the Statoil and BP Alliance. This well was the first well drilled in Deepwater Nigeria and is a reported hydrocarbon discovery. Although the well was within the Niger Delta depositional system, the deepwater play types drilled were quite different than anything previously tested on the Nigerian shelf or onshore. One year on, some of the questions to be asked are: (1) What did Oyo-1 discover? (2) What has been done to establish the commerciality, or otherwise, of the hydrocarbon pools encountered? (3) What impact does this discovery have on other prospects identified in the deepwater area? The answer to these questions will help to identify whether a new hydrocarbon province in the deepwater Nigeria area can be developed, or not.

    We study the detailed dynamics of a solar prominence tornado using time series of 171, 304, 193 and 211 {\\AA} spectral lines obtained by Solar Dynamics Observatory/ Atmospheric Imaging Assembly during 2012 November 7-8. The tornado first appeared at 08:00 UT, November 07, near the surface, gradually rose upwards with the mean speed of $\\sim$ 1.5 km s$^{-1}$ and persisted over 30 hr. Time-distance plots show two patterns of quasi-periodic transverse displacements of the tornado axis with periods of 40 and 50 minute at different phases of the tornado evolution. The first pattern occurred during the rising phase and can be explained by the upward motion of the twisted tornado. The second pattern occurred during the later stage of evolution when the tornado already stopped rising and could be caused either by MHD kink waves in the tornado or by the rotation of two tornado threads around a common axis. The later hypothesis is supported by the fact that the tornado sometimes showed a double structure during the qua...

    Certain oscillatory features in the primordial scalar power spectrum are known to provide a better fit to the outliers in the cosmic microwave background data near the multipole moments of l = 22 and 40. These features are usually generated by introducing a step in the popular, quadratic potential describing the canonical scalar field. Such a model will be ruled out, if the tensors remain undetected at a level corresponding to a tensor-to-scalar ratio of, say, r ? 0.1. In this work, in addition to the popular quadratic potential, we investigate the effects of the step in a small field model and a tachyon model. With possible applications to future datasets (such as PLANCK) in mind, we evaluate the tensor power spectrum exactly, and include its contribution in our analysis. We compare the models with the WMAP (five as well as seven-year), the QUaD and the ACBAR data. As expected, a step at a particular location and of a suitable magnitude and width is found to improve the fit to the outliers (near l = 22 and 40) in all these cases. We point out that, if the tensors prove to be small (say, r?<0.01), the quadratic potential and the tachyon model will cease to be viable, and more attention will need to be paid to examples such as the small field models.

    During the project period we continued to conduct long-term (multi-year) measurements, analysis, and modeling of energy and mass exchange in and over a deciduous forest in the Midwestern United States, to enhance the understanding of soil-vegetation-atmosphere exchange of carbon. At the time when this report was prepared, results from nine years of measurements (1998 - 2006) of above canopy CO2 and energy fluxes at the AmeriFlux site in the Morgan-Monroe State Forest, Indiana, USA (see Table 1), were available on the Fluxnet database, and the hourly CO2 fluxes for 2007 are presented here (see Figure 1). The annual sequestration of atmospheric carbon by the forest is determined to be between 240 and 420 g C m-2 a-1 for the first ten years. These estimates are based on eddy covariance measurements above the forest, with a gap-filling scheme based on soil temperature and photosynthetically active radiation. Data gaps result from missing data or measurements that were rejected in qua)lity control (e.g., during calm nights). Complementary measurements of ecological variables (i.e. inventory method), provided an alternative method to quantify net carbon uptake by the forest, partition carbon allocation in each ecosystem components, and reduce uncertainty on annual net ecosystem productivity (NEP). Biometric datasets are available on the Fluxnext database since 1998 (with the exclusion of 2006). Analysis for year 2007 is under completion.

    Graphical abstract: - Highlights: Stress and Young's modulus of poly-SiGe film are linked to the grain columnar structure. The above properties remain unchanged for poly-SiGe films thicker than 40 nm. The point of transition is close to the electron mean free path for SiGe. Both the resistivity and Hall mobility follow a similar trend. - Abstract: As lateral dimensions of electromechanical devices are scaled down to length scales comparable to electron mean free paths, the influence of thickness effect on their properties becomes sine qua non. This paper presents a detailed study of thickness effect on the Young's modulus, residual stress, resistivity and Hall mobility of ultrathin poly-Si{sub 11}Ge{sub 89} films deposited by low pressure chemical vapour deposition. The Young's moduli for the films thicker than ?40 nm are close to the bulk value (135 GPa) while those of the thinner films are much lower. The reduction in resistivity and subsequent improved Hall mobility as thickness increases are discussed in light of surface morphology which is evident from atomic microscopy images. The near constant values of Young's modulus, resistivity and Hall mobility for the films thicker than ?40 nm are attributed to the columnar grain structure as confirmed by the transmission electron microscopy images.

    Significant rightholding changes took place in central and southern Africa during 1987. Angola, Benin, Congo, Gabon, Ghana, Guinea, Guinea Bissau, Mauritania, Seychelles, Somali Republic, Tanzania, Zaire, and Zambia announced awards or acreage open for bidding. Decreases in exploratory rightholdings occurred in Cameroon, Congo, Cote d'Ivoire, Equatorial Guinea, Gabon, Kenya, Namibia, South Africa, and Tanzania. More wells and greater footage were drilled in 1987 than in 1986. Total wells increased by 18% as 254 wells were completed compared to 217 in 1986. Footage drilled during the year increased by 46% as about 1.9 million ft were drilled compared to about 1.3 million ft in 1986. The success rate for exploration wells in 1987 improved slightly to 36% compared to 34% in 1986. Significant discoveries were made in Nigeria, Angola, Congo, and Gabon. Seismic acquisition in 1987 was the major geophysical activity during the year. Total oil production in 1987 was 773 million bbl (about 2.1 million b/d), a decrease of 7%. The decrease is mostly due to a 14% drop in Nigerian production, which comprises 60% of total regional production. The production share of OPEC countries (Nigeria and Gabon) versus non-OPEC countries of 67% remained unchanged from 1986. 24 figs., 5 tabs.

    The Nigerian coal industry was studied. The focus was on the problems which have caused low production output of coal. More specifically, the study examined the present techniques of coal production, the causes of low production of coal, the coal production policy as it affected this study, and proposed policy measures to address the findings. It was discovered that some of the limiting factors to coal production in Nigeria could be attributed to the lack of the following: (i) clear and specific production-demand targets set for coal in Nigeria; (ii) adequate technological capability to mechanize coal mining operations in Nigeria; (iii) venture capital to invest in coal production; (iv) poor infrastructural facilities for coal production such as mining, storage, transportation, etc. It was also discovered that the dissatisfaction of the miners with their conditions of service influenced production capacity negatively. These findings point to the reality that coal is unlikely to play a major role in the country's energy equation in the near future unless serious efforts are made to address the above issues.

    OPL 210 lies in deepwater on the northwestern flank of the Niger Delta. The partners in this block are Allied Energy and The Statoil and BP Alliance. The license has a 5 year initial exploration phase and carries a 2 well commitment. At present the database comprises a 1 x 1 km grid of 2D seismic across the block, and 450 sq. km of 3D in an area of special interest. A larger 3D survey is planned for 1995. Little is known about the reservoir in the deep water, but we expect our main target to be ponded slope and basin turbidites. As such the bulk of the shelf well data available has little or no relevance to the play type likely to be encountered. Prior to drilling, seismic stratigraphy has been one of several methods used to generate a consistent predictive reservoir model. The excellent quality and high resolution of the 3D data have allowed identification and detailed description of several distinctive seismic facies. These facies are described in terms of their internal geometries and stacking patterns. The geometries are then interpreted based on a knowledge of depositional processes from analog slope settings. This enables a predictive model to be constructed for the distribution of reservoir within the observed facies. These predictions will be tested by one of the first wells drilled in the Nigerian deepwater in mid 1995.

    Allied Energy and the Statoil and BP Alliance are currently partners in the OPL 210 license, in deepwater Nigeria. The license has a 5 year initial exploration phase which carries a two well commitment. To optimize the location of these wells in this challenging and costly drilling environment the partnership has decided to acquire extensive exploration 3D seismic data within the block. Interpretation of the first of two planned 3D surveys has led to a much clearer understanding of: (a) The structural segmentation of the prospect and thus a clearer idea of the likely hydrocarbon pool size. (b) The distribution of amplitude anomalies and thus, hopefully, a superior understanding of reservoir distribution and hydrocarbons. Here the limiting factor is clearly the lack of deepwater geophysical calibration, due to the absence of wells. Consequently, conclusions at this stage, are qualitative either than quantative. Combined with detailed seismic stratigraphic and high tech geophysical analysis, these two aspects will assist in the highgrading of segments in the prospect, prior to final decisions on the well locations. The first well, planned for 1995, will be one of the first wells drilled in the Nigerian deepwater area. Examples of both 2D and 3D data will be used to demonstrate the above and some of the first well results will be integrated into our interpretation to highlight how some of our perceptions may have changed.

  5. Dualities and Emergent Gravity: Gauge/Gravity Duality

    E-Print Network [OSTI]

    Sebastian de Haro


    In this paper I develop a framework for relating dualities and emergence: two notions that are close to each other but also exclude one another. I adopt the conception of duality as 'isomorphism', cashing it out in terms of three conditions. These three conditions prompt two conceptually different ways in which a duality can be modified to make room for emergence; and I argue that this exhausts the possibilities for combining dualities and emergence (via coarse-graining). I apply this framework to gauge/gravity dualities, considering in detail three examples: AdS/CFT, Verlinde's scheme, and black holes. My main point about gauge/gravity dualities is that the theories involved, qua theories of gravity, must be background-independent. I distinguish two senses of background-independence: (i) minimalistic and (ii) extended. The former is sufficiently strong to allow for a consistent theory of quantum gravity; and AdS/CFT is background-independent on this account; while Verlinde's scheme best fits the extended sense. I argue that this extended sense should be applied with some caution: on pain of throwing the baby (general relativity) out with the bath-water (extended background-independence). Nevertheless, it is an interesting and potentially fruitful heuristic principle for quantum gravity theory construction. The interpretation of dualities is articulated in terms of: (i) epistemic and metaphysical commitments; (ii) parts vs. wholes. I then analyse the emergence of gravity in gauge/gravity dualities in terms of the two available conceptualisations of emergence; and I show how emergence in AdS/CFT and in Verlinde's scenario differ from each other. Finally, I give a novel derivation of the Bekenstein-Hawking black hole entropy formula based on Verlinde's scheme; the derivation sheds light on several aspects of Verlinde's scheme and how it compares to Bekenstein's original calculation.

    All exploratory activity in central and southern Africa decreased in 1983, reflecting world economic conditions and excess productive capacity. Seismic activity has declined sharply from its peak year of 1981. Land operations suffered the greatest drop in 1983, whereas party-months of marine work increased slightly. 3-D recording continued to be used but at a reduced rate compared with 1982. Large aeromagnetic surveys were made in several countries; however, the coverage was less than in 1982. Gravity continues to be used to supplement other geophysical work, but other exploratory techniques are being used infrequently. Total wells drilled dropped from 464 in 1982 to 387 in 1983. Most of the decline was in exploratory drilling, which dropped from 132 to 86 wells. This was reflected in the number of discoveries, which decreased from 48 to 27 while the success rate continued about the same. Development drilling continued at a high level in Cameroon and Congo, whereas in Nigeria the emphasis shifted to the drilling of appraisal wells. In all, 2,937,708 ft (895,643 m) of hole was drilled, a decrease of about 20% from 1982. Oil production of 673,075,667 bbl in 1983 was an increase of 1.7% over 1982's production, bringing cumulative production to over 12 billion bbl. Marked increases in production were recorded in Cabinda, Ivory Coast, and Congo. Production from Nigerian fields continued to dominate this part of the world as they contributed about 67% of the annual production and 75% of the cumulative production. 44 figures, 15 tables.

    Determining optimal surveillance networks for an emerging pathogen is difficult since it is not known beforehand what the characteristics of a pathogen will be or where it will emerge. The resources for surveillance of infectious diseases in animals and wildlife are often limited and mathematical modeling can play a supporting role in examining a wide range of scenarios of pathogen spread. We demonstrate how a hierarchy of mathematical and statistical tools can be used in surveillance planning help guide successful surveillance and mitigation policies for a wide range of zoonotic pathogens. The model forecasts can help clarify the complexities ofmorepotential scenarios, and optimize biosurveillance programs for rapidly detecting infectious diseases. Using the highly pathogenic zoonotic H5N1 avian influenza 2006-2007 epidemic in Nigeria as an example, we determined the risk for infection for localized areas in an outbreak and designed biosurveillance stations that are effective for different pathogen strains and a range of possible outbreak locations. We created a general multi-scale, multi-host stochastic SEIR epidemiological network model, with both short and long-range movement, to simulate the spread of an infectious disease through Nigerian human, poultry, backyard duck, and wild bird populations. We chose parameter ranges specific to avian influenza (but not to a particular strain) and used a Latin hypercube sample experimental design to investigate epidemic predictions in a thousand simulations. We ranked the risk of local regions by the number of times they became infected in the ensemble of simulations. These spatial statistics were then complied into a potential risk map of infection. Finally, we validated the results with a known outbreak, using spatial analysis of all the simulation runs to show the progression matched closely with the observed location of the farms infected in the 2006-2007 epidemic.less

    Presently, Nigeria is one of the fastest growing Telecom markets in the world. The country's teledensity increased from a mere 0.4 in 1999 to 10 in 2005 following the liberalization of the Telecom sector in 2001. More than 25 million new digital mobile lines have been connected by June 2006. Large quantities of mobile phones and accessories including secondhand and remanufactured products are being imported to meet the pent-up demand. This improvement in mobile telecom services resulted in the preference of mobile telecom services to fixed lines. Consequently, the contribution of fixed lines decreased from about 95% in year 2000 to less than 10% in March 2005. This phenomenal progress in information technology has resulted in the generation of large quantities of electronic waste (e-waste) in the country. Abandoned fixed line telephone sets estimated at 120,000 units are either disposed or stockpiled. Increasing quantities of waste mobile phones estimated at 8 million units by 2007, and accessories will be generated. With no material recovery facility for e-waste and/or appropriate solid waste management infrastructure in place, these waste materials end up in open dumps and unlined landfills. These practices create the potential for the release of toxic metals and halocarbons from batteries, printed wiring boards, liquid crystal display and plastic housing units. This paper presents an overview of the developments in the Nigerian Telecom sector, the material in-flow of mobile phones, and the implications of the management practices for wastes from the Telecom sector in the country.

  10. Final work plan : phase I investigation of potential contamination at the former CCC/USDA grain storage facility in Montgomery City, Missouri.

    From September 1949 until September 1966, the Commodity Credit Corporation of the U.S. Department of Agriculture (CCC/USDA) leased property at the southeastern end of Montgomery City, Missouri, for the operation of a grain storage facility. During this time, commercial grain fumigants containing carbon tetrachloride were commonly used by the CCC/USDA and the private grain storage industry to preserve grain in their facilities. In January 2000, carbon tetrachloride was detected in a soil sample (220 {micro}g/kg) and two soil gas samples (58 {micro}g/m{sup 3} and 550 {micro}g/m{sup 3}) collected at the former CCC/USDA facility, as a result of a pre-CERCLIS site screening investigation (SSI) performed by TN & Associates, Inc., on behalf of the U.S. Environmental Protection Agency (EPA), Region VII (MoDNR 2001). In June 2001, the Missouri Department of Natural Resources (MoDNR) conducted further sampling of the soils and groundwater at the former CCC/USDA facility as part of a preliminary assessment/site inspection (PA/SI). The MoDNR confirmed the presence of carbon tetrachloride (at a maximum identified concentration of 2,810 {micro}g/kg) and chloroform (maximum 82 {micro}g/kg) in the soils and also detected carbon tetrachloride and chloroform (42.2 {micro}g/L and 58.4 {micro}g/L, respectively) in a groundwater sample collected at the former facility (MoDNR 2001). The carbon tetrachloride levels identified in the soils and groundwater are above the default target level (DTL) values established by the MoDNR for this contaminant in soils of all types (79.6 {micro}g/kg) and in groundwater (5.0 {micro}g/L), as outlined in Missouri Risk-Based Corrective Action (MRBCA): Departmental Technical Guidance (MoDNR 2006a). The corresponding MRBCA DTL values for chloroform are 76.6 {micro}g/kg in soils of all types and 80 {micro}g/L in groundwater. Because the observed contamination at Montgomery City might be linked to the past use of carbon tetrachloride-based fumigants at its former grain storage facility, the CCC/USDA will conduct investigations to (1) characterize the source(s), extent, and factors controlling the possible subsurface distribution and movement of carbon tetrachloride at the Montgomery City site and (2) evaluate the health and environmental threats potentially represented by the contamination. This work will be performed in accord with the Intergovernmental Agreement established between the Farm Service Agency of the USDA and the MoDNR, to address carbon tetrachloride contamination potentially associated with a number of former CCC/USDA grain storage facilities in Missouri. The investigations at Montgomery City will be conducted on behalf of the CCC/USDA by the Environmental Science Division of Argonne National Laboratory. Argonne is a nonprofit, multidisciplinary research center operated by UChicago Argonne, LLC, for the U.S. Department of Energy (DOE). The CCC/USDA has entered into an agreement with DOE, under which Argonne provides technical assistance to the CCC/USDA with environmental site characterization and remediation at its former grain storage facilities. The site characterization at Montgomery City will take place in phases. This approach is recommended by the CCC/USDA and Argonne, so that information obtained and interpretations developed during each incremental stage of the investigation can be used most effectively to guide subsequent phases of the program. This site-specific Work Plan outlines the specific technical objectives and scope of work proposed for Phase I of the Montgomery City investigation. This Work Plan also includes the community relations plan to be followed throughout the CCC/USDA program at the Montgomery City site. Argonne is developing a Master Work Plan specific to operations in the state of Missouri. In the meantime, Argonne has issued a Provisional Master Work Plan (PMWP; Argonne 2007) that has been reviewed and approved by the MoDNR for current use. The PMWP (Argonne 2007) provides detailed information and guidance on the investigative technologies, analytical methodologies, qua
