    Full Text Available The thermal upgrading of Nigerian petroleum residue was studied at relatively low pressure in a delayed coking reactor system. In this work, the intent was to investigate the effects of process variables such as reaction temperature (200(0C to 600(0C, reaction time (0 to 120min, additive concentration loading and additive-to-residue ratio on the amounts and quality of organic liquid product (OLP. The liquid products derived from the delayed coking process were characterized by means of instrumental analysis of gas-liquid chromatography. Results obtained from the analyses of the OLP revealed an upward trend of the conversion process and the selectivity of the aromatic compounds with additive-to-residue ratio (ARR and increase in temperature. This led to maximum yield of 37.2% achieved with ARR of 5 compared to 31% achieved with ordinary thermal conversion. The selectivity for aromatic hydrocarbons was maximum at 83.1wt% the selectivity towards aromatics and aliphatic hydrocarbons were highest for methanol-potassium hydroxide and methanol respectively. In all additive system cases, maximum OLP was produced at an optimum reaction temperature of 370(0C in the delayed coking reactor and at higher residence time. The gaseous product consisted of carbon monoxide and carbon dioxide and C1 - C6 hydrocarbons, which amounted to about 20 to 30 wt% of liquid distillate. The information obtained in this study show that the organic liquid products are amenable to characterization procedure and provided the basis for the identification of processes for upgrading Nigerian petroleum residue and such other starting materials such as bitumen or fossil fuel coal liquids.

    The oil extraction and production industry generates several types of solid and liquid wastes. Scales, sludge and water are typical residues that can be found in such facilities and that can be contaminated with Naturally Occurring Radioactive Material (N.O.R.M.). As a result of oil processing, the natural radionuclides can be concentrated in such residues, forming the so called Technologically Enhanced Naturally Occurring Radioactive Material, or T.E.N.O.R.M.. Most of the radionuclides that appear in oil and gas streams belong to the {sup 238}U and {sup 232}Th natural series, besides 40 K. The present work was developed to determine the radionuclide content of scales and sludge generated during oil extraction and production operations. Emphasis was given to the quantification of {sup 226}Ra, {sup 228}Ra and 40 K since these radionuclides,are responsible for most of the external exposure in such facilities. Samples were taken from the P.E.T.R.O.B.R.A.S. unity in the State of Sergipe, in Northeastern Brazil. They were collected directly from the inner surface of water pipes and storage tanks, or from barrels stored in the waste storage area of the E and P unit. The activity concentrations for {sup 226}Ra, {sup 228}Ra and 40 K were determined by using an HP Ge gamma spectrometric system. The results showed concentrations ranging from 42.7 to 2,110.0 kBq/kg for {sup 226}Ra, 40.5 to 1,550.0 kBq/kg for {sup 228}Ra, and 20.6 to 186.6 kBq/kg for 40 K. The results highlight the importance of determining the activity concentration of those radionuclides in oil residues before deciding whether they should be stored or discarded to the environment.

    Petroleum coke residual oil slurry (POS) is one of prospect substitute of oil burned in many industrial boilers and utilities in China. It is a mixture of pulverized petroleum coke, residual oil and slurry oil. We carried out a series of experiments to study its ignition and combustion mechanism. Experimental results show that the ignition temperature of petroleum coke is higher than normal anthracite and meager coal, and it is difficult to be burned in oil-fired furnace directly. The petroleum coke`s combustion property is improved greatly after mixing with residual oil and slurry oil. The combustion process of POS can be divided into three phases: preheating, kindling and homogenous combustion, burning of the petroleum coke residue. The combustion condition of POS is close to bituminous and coal-oil-mixture (COM).

    We evaluated how gas-phase O3 interacts with residual petroleum hydrocarbons in soil. Total petroleum hydrocarbons (TPH) were 18 ± 0.6 g/kg soil, and TPH carbon constituted ∼40% of the dichloromethane-extractable carbon (DeOC) in the soil. At the benchmark dose of 3.4 kg O3/kg initial TPH, TPH carbon was reduced by nearly 6 gC/kg soil (40%), which was accompanied by an increase of about 4 gC/kg soil in dissolved organic carbon (DOC) and a 4-fold increase in 5-day biochemical oxygen demand (BOD5). Disrupting gas channeling in the soil improved mass transport of O3 to TPH bound to soil and increased TPH removal. Ozonation resulted in two measurable alterations of the composition of the organic carbon. First, part of DeOC was converted to DOC (∼4.1 gC/kg soil), 75% of which was not extractable by dichloromethane. Second, the DeOC containing saturates, aromatics, resins, and asphaltenes (SARA), was partially oxidized, resulting in a decline in saturates and aromatics, but increases in resins and asphaltenes. Ozone attack on resins, asphaltenes, and soil organic matter led to the production of NO3(-), SO4(2-), and PO4(3-). The results illuminate the mechanisms by which ozone gas interacted with the weathered petroleum residuals in soil to generate soluble and biodegradable products.

    The oil-rich Niger Delta suffers from extensive petroleum contamination. A pilot study was conducted in the region of Ogoniland where one community, Ogale, has drinking water wells highly contaminated with a refined oil product. In a 2011 study, the United Nations Environment Programme (UNEP) sampled Ogale drinking water wells and detected numerous petroleum hydrocarbons, including benzene at concentrations as much as 1800 times higher than the USEPA drinking water standard. UNEP recommended immediate provision of clean drinking water, medical surveillance, and a prospective cohort study. Although the Nigerian government has provided emergency drinking water, other UNEP recommendations have not been implemented. We aimed to (i) follow up on UNEP recommendations by investigating health symptoms associated with exposure to contaminated water; and (ii) assess the adequacy and utilization of the government-supplied emergency drinking water. We recruited 200 participants from Ogale and a reference community, Eteo, and administered questionnaires to investigate water use, perceived water safety, and self-reported health symptoms. Our multivariate regression analyses show statistically significant associations between exposure to Ogale drinking water and self-reported health symptoms consistent with petroleum exposure. Participants in Ogale more frequently reported health symptoms related to neurological effects (OR = 2.8), hematological effects (OR = 3.3), and irritation (OR = 2.7). Our results are the first from a community relying on drinking water with such extremely high concentrations of benzene and other hydrocarbons. The ongoing exposure and these pilot study results highlight the need for more refined investigation as recommended by UNEP.

    Thermal decomposition under nitrogen of sugarcane bagasse, petroleum residue and their blends was studied by thermogravimetry (TG) at different heating rates (10, 20 and 60 deg C/min). Thermal decomposition kinetic parameters were determined. Sugarcane bagasse pyrolysis was described as the sum of cellulose, hemicellulose, and lignin individual contributions. First order equations were used to determine the bagasse component thermal decomposition kinetics. Activation energies calculated were 235, 105, and 26 kJ/mol for cellulose, hemiceullose and lignin, respectively. Thermal decomposition of petroleum residue can be explained by the additive effect of its three major fractions, following kinetic equation orders of 2.5, 2.3 and 1.5 with activation energies of 100, 180 and 220 kJ/mol respectively. It has been found that during thermal decomposition of bagasse/petroleum residue mixtures, no significant interaction occurred in the solid phase between the components under the experimental conditions investigated. The kinetic parameters associated with the bagasse/petroleum residue mixture involved the sum of bagasse and petroleum residue individual component kinetic parameters. The information obtained can be used to develop a correlation between the thermogravimetric data and the feedstock composition. 55 refs., 13 figs., 7 tabs.

    Incipient coke formation was studied by heating a heavy hydrocarbon residue in isothermal batch reactor at atmospheric pressure of nitrogen at temperatures 320, 357, and 387{sup o}C over times from 0 to 7 h. The kinetics of coke formation was followed by solvent extraction (insolubility in hexane (HI), toluene (TI)) and as development of HI and TI approximate to apparent first-order kinetics. Results appeared to follow the Wiehe's phase separation model for coke formation. The density of the pyrolysis residues was found to be independent of condition and it shows a linear relation to TI content. 16 refs., 6 figs., 2 tabs.

    Sea turtles found dead when the Ixtoc I oil spill reached Texas waters were necropsied and tissues were analyzed for residues of petroleum hydrocarbons. Two of the three turtles were in poor flesh, but had no apparent oil-caused lesions. There was evidence of oil in all tissues examined and indications that the exposure had been chronic. Comparisons with results of studies done on birds indicate consumption of 50,000 ppm or more of oil in the diet. Some possible mechanisms of mortality are suggested.

    The aims of this study were to determine the compositions and residual properties of petroleum hydrocarbon in soil, as well as to identify the source and weathering degree of the pollution. A total of 5 producing wells in Gudao and Hekou oil producing region of Shengli oilfields were analyzed. More than 50 individual target compounds including straight-and branched-chain alkanes( n-alkanes, pristine and phytane) and polycyclic aromatic hydrocarbons (PAHs) in soil samples and crude oil were determined by gas chromatography-mass spectrometry (GC-MS). The percentages of chain alkanes and PAHs in total solvent extractable matters(TSEM) of soil samples were both much lower than those in the crude oil samples. The compositions of petroleum hydrocarbon in soil samples differed from those in crude oil, which indicated the n-alkanes with carbon numbers oil contaminated soils, the relationship between the index and petroleum hydrocarbon compounds was analyzed using principal component analysis (PCA). The results showed that the n-alkanes with carbon numbers > 33 and the PAHs with rings between 3 and 5 were much harder to degrade. PCA of 4 indexes for source identification revealed more than 50% of the soil samples were polluted by crude oil, which needs more attention during remediation.

    Full Text Available This review gives a brief overview of developments in the analysis of petroleum products (PP in fire debris residues (FDR by gas chromatography (GC. The review covers different aspects of analysis such as the substrates involved, isolation procedures, column and mobile phase used, and subsequent detection in tabular form. This paper covers detection of PP such as petrol, kerosene, and diesel in various types’ of samples of interest to fire debris analysts. Solid phase microextraction is most frequently used along with gas chromatography-mass spectrometry (GC-MS for the extraction and identification of PP from FDR. Chemometric tools should be used to improve the significance and reliability of results obtained from the analysis of FDR. However, the potential utility of portable GC-MS in fire debris analysis cannot be ignored, and its proper development and validation is required before using it for this purpose.

    A study was performed to determine the potential of two-liquid-phase (TLP) bioslurry reactors using silicon oil as solvent for degradation of residual contaminants in petroleum-contaminated soil. The residues were characterized by gas chromatography-mass spectrometry and electrospray ionization Fourier transform ion cyclotron resonance mass spectrometry. This allowed for the identification of a mixture of residual biomarkers, metabolic byproducts, oxygenated and hetero-polynuclear aromatic hydrocarbons in the contaminated soil. The removal amount of total extractable organics (TEO) was 15900mgkg(-1) soil in the TLP reactor within 12weeks. However, TEO remained intact in the bioslurry reactor without the addition of silicon oil for the duration of the experiment, due to high toxicity of metabolites to the microorganisms. The availability of TEO was calculated using a mild extraction with Triton X-100, and the amount of TEO extracted was in accord with the amount of biodegraded TEO. Significantly reduced toxicity in soil was observed at week 12 through TLP remediation. Dehydrogenase activity in the bioslurry reactor was strongly suppressed. Fluorescein diacetate was significantly hydrolyzed by the composition of bioremediation residues in the contaminated soil. Microbial adhesion to the solvent was revealed by the determination of microbial activity in the water-immiscible-liquid.

    The Deepwater Horizon spill released crude oil into the Gulf of Mexico over a period of 3 months in 2010. Barataria Bay, Louisiana was among the most heavily impacted and extensively oil-contaminated coastlines. Studies conducted in the marshes show significant ecological and geologic effects from oil residues that reached the bay. Observation of the presence of an oil sheen associated with sediment disturbance raised the question as to whether petroleum residues were also present in the sediments of Barataria Bay. In order to address this question, six sediment cores were collected from non-oiled (#1 & 2) and oiled (#3-6) portions of Barataria Bay approximately one year after the Deepwater Horizon oil spill. Concentrations of n-alkanes, unresolved complex material (UCM) and polycyclic aromatic hydrocarbon (PAH) were determined in these upper sediments. In addition, concentrations of phospholipid fatty acids (PLFA) were determined to assess variations in microbial community abundance. Alkane concentrations ranged from 134 to 747 ng/g with chain lengths from C12 to C35. Most cores showed an odd over even preference (carbon preference index of 1.2 to 4.3) with highest concentrations of long chain compounds between C24 and C35 (average chain length 29 to 39), consistent with a terrestrial carbon source such as plant waxes. Core #6 however, in the southwest portion of the bay, had the lowest concentrations of alkanes, and shorter n-alkane chain lengths overall. Despite this difference, the core maintains a relatively high carbon preference index and average chain length compared to that which would be expected from oil contaminated sediments. Measured PAH concentrations were highly variable ranging from undetectable to 436 ng/g. These values are several orders of magnitude lower than what is generally seen in highly contaminated sediments. Further, UCM concentrations were negligible in the cores from the oiled regions. These findings suggest only a minimal presence of

    Size-exclusion chromatography (SEC) using 1-methyl-2-pyrrolidinone (NMP) as eluent has been calibrated using various standard polymers and model compounds and applied to the analysis of extracts of coal, petroleum and kerogens, to petroleum vacuum residues, soots, biomass tars and humic substances. Three separate columns of different molecular mass (MM) ranges were used, with detection by UV absorption; an evaporative light scattering detector was used for samples with no UV absorption. Fractionation was useful to separate signal from the less abundant high-mass material, which was normally masked by the strong signal from the more abundant low-mass material in the absence of fractionation. Fractionation methods used to isolate high-mass materials before SEC analysis included planar chromatography, column chromatography and solvent solubility. The apparently large molecules were concentrated into the fractions not soluble in common solvents and were relatively immobile in planar chromatography. All samples and fractions contained some material excluded from the column porosity. Evidence from other techniques suggests that the excluded material is of different structures from that of the resolved material rather than consisting of aggregates of small molecules. We speculate that the excluded material may elute early because the structures of this material are three-dimensional rather than planar or near planar.

    Correlation models for light olefin yields from residue catalytic pyrolysis are studied. Experiments are carried out in a confined fluidized bed reactor for Daqing (China) atmospheric residue catalytic pyrolysis over LCM-5 pyrolyzing catalyst. The influences of reaction temperature, residence time and the weight ratios of catalyst-to-oil and steam-to-oil on light olefin yields are researched. Correlation models for light olefin yields are established, and the model parameters obtained, with the least square method. Results for error analysis and the F-statistical test show that the correlation models have high calculation precision.

    The spatio-temporal distribution and the controlling factors of petroleum hydrocarbons (PHCs) in sediments of Chilika lagoon was investigated. Samples were collected during three seasons and quantified using UV-fluorescence spectroscopy. Concentrations of PHCs in surface sediments varies from 0.18 to 12.13 ppm (mean 3.71 ± 3.94 ppm). Compared to the lagoon, the monitoring stations adjacent to jetties with high boating activities tend to have higher PHC concentrations, suggesting that the contribution is likely to be from fossil fuel combustion and accidental seepage. The sediment organic matter (OM) of Chilika ranges from 0.26% to 6.23%. PHC maintains a positive correlation with OM (p < 0.05; f = 0.334), indicating the long term deposition of PHC as sediment OM. However, there is no significant relation between PHC and sediment texture, indicating its negligible control over PHC. The recorded PHC concentrations are below the threshold limit (70 ppm) as classified by United States (US) National Academy of Sciences (NAS) and also lower than those reported from similar ecosystems in India and overseas. Since the long term deposition and the bioaccumulation of PHC cannot be avoided, it is essential to monitor these parameters periodically.

    Strain F11(T), a phenanthrene-degrading bacterium, was isolated from a petroleum residue treatment system, and classified under the genus Rhizobium based on the similarity analysis of its 16S rRNA and recA gene sequences. Strain F11(T) falls into the same phylogenetic clade with Rhizobium oryzae Alt 505(T) (96.8% 16S rRNA gene sequence similarity) and Rhizobium pseudoryzae J34A-127(T) (96.2%). Major cellular fatty acids of strain F11(T) are C(16:0) (6.24%) and summed feature 8 (C(18:1ω7c) and/or C(18:1ω6c), 76.59%), which are also the major fatty acids of R. oryzae Alt 505(T) and R. pseudoryzae J34A-127(T). The DNA G+C content of strain F11(T) was 59.3±0.4 mol%. Based on the phylogenetic analysis as well as biochemical and physiological characteristics, strain F11(T) could be separated from all recognized Rhizobium species. Strain F11(T) (=DSM 21882(T) =CCTCC AB 209029(T)) was considered to be representative of a novel species of Rhizobium, for which the name Rhizobium phenanthrenilyticum sp. nov. is proposed.

    In the heavy oil hydrodemetallization, factors which have and influence on the reactivity were studied. Four different heavy oils, Khafji and Gach Saran atmospheric residues, and Morichal and Tia Juana crudes, were subjected to an experiment. Fixed-bed hydrotreatments were conducted under an identical reaction condition, hydrogen pressure 100 kg/cm{sup 2}, LHSV 1.0 h{sup {minus}1}, reaction temperature 380-420{degree}C. Such parameters as V, Ni, asphaltenes (APs) and sulfur contents were not related to the reactivity toward hydrodemetallization of each feedstock. Instead, the molecular size distribution of APs determined by GPC and NMR structural parameters of APs such as the degree of condensation of aromatic rings, the number of aromatic rings per molecule and the molecular weight of structural unit were seemed to correlate well with the reactivity. Hydrodemetallization proceeded more easily for the feedstocks whose APs are smaller in molecular size and lower both in the unit sheet weight and the degree of aromatic ring condensation. The reaction of metals removal is strongly influenced by the intraparticle diffusion of Ap molecules. Ni was more difficult to be removed than V. The main reason for this was considered to be that the reaction of Ni removal depends much on the degree of AP cracking. 13 refs., 8 figs., 5 tabs.

    The hydrogen potential contained in waste plastics is to be utilized optimally for cracking of petroleum residues. Homogeneous distribution of the plastic particles in the petroleum residue is to ensure short distances between the hydrogen donor and acceptor, a sufficently large reaction surface, and stable mixing for further processing. Apart from homogeneity, another factor of interest is the influence of mixed-in polymer particles on the colloidal stability of the petroleum residue and the physico-chemical properties of the mixtures. With a view to further processing, the mixtures were analyzed for high-temperature stability, flow characteristics, and reaction behaviour during pyrolysis. (orig.) [Deutsch] Ziel dieses Vorhabens ist es, das in den Kunststoffabfaellen vorhandene Wasserstoffpotential optimal fuer eine tiefergehende Spaltung der Erdoelrueckstaende nutzbar zu machen. Durch eine homogene Verteilung der Kunststoffpartikel im Erdoelrueckstand soll ein moeglichst kurzer Transportweg zwischen Wasserstoff-Donor und -Akkzeptor, eine ausreichend grosse Reaktionsoberflaeche und eine fuer weitere Verarbeitungsschritte notwendige stabile Mischung erreicht werden. Ebenso interessant wie die Homogenitaet solcher Gemische ist auch der Einfluss der eingemengten Polymerteilchen auf die Kolloidstabilitaet des Erdoelrueckstandes und die physikalisch-chemischen Eigenschaften der Mischungen. Im Hinblick auf eine technische Weiterverarbeitung werden die Gemische besonders auf ihre Stabilitaet bei erhoehten Temperaturen (Heisslagerstabilitaet), ihr Fliessverhalten sowie ihr Reaktionsverhalten waehrend der Pyrolyse untersucht.

    Undesirable residue formation and lower performance can be observed during the use of polymer-based chemical additives in the petroleum industry when such compounds are mixed during a number of operations, such as oil production. In this work a demulsifier, a flocculant and a scale inhibitor and their respective polymeric bases were tested. These were evaluated through specific performance tests for each additive and a solubility test to assess residue formation. By correlating the performance of commercial additives and the respective polymeric bases, we can conclude that the polymeric base is responsible for the positive synergistic effects on demulsifier performance in the presence of other additives and for the negative synergistic effects on scale-inhibiting performance, also in the presence of other additives. Moreover, we found that the polymeric base can be responsible for the residue formation from the scale inhibitor and flocculant mixture, although it is not be responsible for the residue formation of the flocculant alone.

    Residual aromatic extracts (RAE) are petroleum substances with variable composition predominantly containing aromatic hydrocarbons with carbon numbers greater than C25. Because of the high boiling nature of RAEs, the aromatics present are high molecular weight, with most above the range of carcinogenic polycyclic aromatic hydrocarbons (PAHs). However, refinery distillations are imperfect; some PAHs and their heteroatom-containing analogs (collectively referred to as polycyclic aromatic content or PAC) may remain in the parent stream and be extracted into the RAE, and overall PAC content is related to the carcinogenic potential of an RAE. We describe here a real-time analytical chemistry-based tool to assess the carcinogenic hazard of RAE via the development of a functional relationship between carcinogenicity and boiling point. Samples representative of steps along the RAE manufacturing process were obtained from five refineries to evaluate relationships between mutagenicity index (MI), PAC ring content and gas chromatographic distillation (GCD) curves. As expected, a positive linear relationship between MI and PAC ring content occurred, most specifically for 3-6 ring PAC (R(2)=0.68). A negative correlation was found between MI and temperature at 5% vaporization by GCD (R(2)=0.72), indicating that samples with greater amounts of lower boiling constituents were more likely to be carcinogenic. The inverse relationship between boiling range and carcinogenicity was further demonstrated by fractionation of select RAE samples (MI=0.50+0.07; PAC=1.70+0.51wt%; n=5) into low and high boiling fractions, where lower boiling fractions were both more carcinogenic than the higher boiling fractions (MI=2.36±0.55 and 0.17±0.11, respectively) and enriched in 3-6 ring PACs (5.20+0.70wt% and 0.97+0.35wt%, respectively). The criteria defining carcinogenicity was established as 479°C for the 5% vaporization points by GCD, with an approximate 95% probability of a future sample having

    Coprocessing of petroleum residues and plastics is a promising technology, although some problems concerning waste plastics must be clarified prior to its implementation. In general, it can be stated that with a careful choice of operating parameter combinations, oil yields will be higher than for thermal treatment of petroleum residues alone (e.g. a 35% yield increase is achieved by adding 25% of plastics, which is a disproportionately high increase). Waste plastics thus become a valuable material for processing. (orig.) [Deutsch] Das untersuchte Coprocessing von VR und Kunststoffen ist ein erfolgversprechender Weg der Kunststoffverwertung und des tiefen Crackens von Erdoelrueckstand. Die Klaerung der mit Altkunststoffen verbundenen Fragen bedarf weiterer Untersuchungen. Allgemein kann festgestellt werden, dass bei entsprechenden Parameterkombinationen bessere Oelausbeuten erzielt werden als bei der thermischen Behandlung von reinem VR. Ein Beispiel dafuer ist in der Abbildung 10 dargestellt. Durch eine 25%-ige Erhoehung der Einsatzstoffmasse durch Kunststoffzugabe wird eine im Vergleich zu reinem VR um ca. 36% hoehere Oelausbeute erzielt, was einer ueberproportionalen Erhoehung entspricht. Altkunststoff wird bei diesem Prozess unter Nutzung des Wasserstoff-potentials von Polymeren zu einem wertvollen Einsatzstoff. (orig.)

  17. Statistical Method of Estimating Nigerian Hydrocarbon Reserves

    Full Text Available Hydrocarbon reserves are basic to planning and investment decisions in Petroleum Industry. Therefore its proper estimation is of considerable importance in oil and gas production. The estimation of hydrocarbon reserves in the Niger Delta Region of Nigeria has been very popular, and very successful, in the Nigerian oil and gas industry for the past 50 years. In order to fully estimate the hydrocarbon potentials in Nigerian Niger Delta Region, a clear understanding of the reserve geology and production history should be acknowledged. Reserves estimation of most fields is often performed through Material Balance and Volumetric methods. Alternatively a simple Estimation Model and Least Squares Regression may be useful or appropriate. This model is based on extrapolation of additional reserve due to exploratory drilling trend and the additional reserve factor which is due to revision of the existing fields. This Estimation model used alongside with Linear Regression Analysis in this study gives improved estimates of the fields considered, hence can be used in other Nigerian Fields with recent production history

    Novel catalysts have been prepared, based on montmorillonite (a natural clay) and laponite (a synthetic clay) pillared with tin, chromium and aluminium pillars as well as layered double hydroxides based on polyoxo-vanadate and -molybdate as previously described. These novel catalysts were compared initially with a standard Ni/Mo catalyst supported on alumina and a dispersed catalyst, Mo(CO){sub 6} in hydrocracking a coal extract for a short contact time of 10 min at 440{sup o}C in a microbomb reactor with tetralin solvent and hydrogen at a pressure of 190 bar. In the present work, the best of the novel catalysts, chromium montmorillonite calcined at 500{sup o}C and tin laponite, have been compared with the supported catalyst and a dispersed catalyst (Mo(CO){sub 6}) in the repeated hydrocracking of fresh coal extract over three sequential periods of 1 h. Also, the chromium montmorillonite calcined at 500{sup o}C has been used in the hydrocracking of primary coal extracts, prepared in the flowing solvent liquefaction rig from Pittsburgh No. 8 and Illinois No. 6 coals, for reaction times of 10 min and 2 h. Further, the chromium montmorillonite calcined at 500{sup o}C and tin laponite, have been compared with the supported catalyst and in the absence of a catalyst, in the hydrocracking of a petroleum distillation residue with 10 min and 2 h reaction times. Results were compared by size exclusion chromatography in NMP solvent and by UV-fluorescence and evaluated by the extent of the shift of the SEC profile to small molecules and by the shift of the synchronous UV-fluorescence profiles to shorter wavelengths. The performances of both catalysts at short, long or repeated reaction times are seen to be better than that of the conventional NiMo catalyst for the hydrocracking of coal-derived materials and a petroleum residue. Trials on a longer time scale are necessary in the next level of evaluation. 37 refs., 14 figs., 1 tab.

    @@ Successful textbooks educate generations,and in a way define generations of scientists. As science and technology advance,textbooks become old and outdated. Nevertheless, each textbook serves as a foundation for the next, and thus a series of textbooks on a particular subject reflects the evolution of concepts, methods and data on the subject. As I write this review, there are eight textbooks on petroleum geology on my bookshelf: D. Hager's Practical Oil Geology (1915) (the first textbook of its kind); W.H. Emmons' Geology of Petroleum (1921), Cecil Lalicker's Principles of Petroleum Geology (1949); William Russell's Principles of Petroleum Geology (1951); Kenneth Landes' Petroleum Geology (1951); A. I. Levorsen's Geology of Petroleum (2nd ed., 1967); F. K. North's Petroleum Geology (1985); and Richard Selley's Elements of Petroleum Geology (2nd ed., 1998). Petroleum Geoscience by Gluyas and Swarbrick is a welcome addition to this list although its authors do not mention their predecessors.

  3. EFFECTIVENESS OF A OIL RESIDUE FROM PETROLEUM ON DIMENSIONAL STABILITY OF Pinus sp. (Pinus AND Mimosa scabrella Bentham (Bracatinga WOOD

    2010-08-01

    Full Text Available In search for alternative uses of a petroliferous oily residue known as “LCO” (Liquid Cycle Oil, its capacity to improve the dimensional stability of the wood was evaluated using Pinus sp. (pinus and Mimosa scabrella Bentham (bracatinga. The LCO was tested in its original composition and also diluted in different proportions into a commercial kerosene. The dimensional stability in the three anatomic axis, volumetric changes, shrinkage and anisotropy coefficients, basic density and 12% relative humidity density changes were evaluated, in different stages during the investigation process. The results show no significant differences in maximum swelling and shrinkage between treated and untreated wood blocks at 5% probability level for both species. However, a reduction in the shrinkage coefficient was observed with the increase of LCO concentration, for both species. In general, pinus showed lowest values in all parameter evaluated. The shrinkage and anisotropy coefficient were higher for bracatinga than pinus, nevertheless, no significant differences were observed between treated and untreated wood blocks. These results indicated that changes between tangential and radial faces were minimal, possible due to a poor penetration of LCO into the cell walls. This result, as a consequence, could be associated with a weak performance of the tested chemical, which could not improve the dimensional stability of wood for both species. The increasing LCO concentrations increased the density of both species at 12% relative humidity. This result could be associated to the presence of part of the chemical remaining in the walls of the cellular lumen and the resiniferous channels. Besides, the external aspect of the treated wood was also other restrictive factor to the use of LCO.

    It turns out of interest to Comision Federal de Electricidad and Petroleos Mexicanos to reduce costs of fuel oil, reducing the viscosity of the residues petroleum of high vacuum distillation emulsifying these with water. The parameters that define the characteristics of the emulsions are mainly the relation of their components, viscosity, size and drop distribution and its stability. The experimental work began producing emulsions in form of lots, using samples of approximately 500 milliliters of vacuum residue. In this first stage, at different concentrations, were examined eight different surfactants, as well as combinations among them, also seven different stabilizers were used. With these tests it has been managed to identify the concentrations, as well as the most adequate relations of surfactants and stabilizers for the production of emulsions of vacuum residues in water. The size and drop distribution has been determined by means of an optical LEICA microscope, model DMLS, that has adapted a photographic system in which an emulsion photo is obtained and, later, a system of analysis of images is used for obtaining of the values of the diameter of the drops present in the emulsion. Finally, by means of statistical software the average size of the particles is obtained, as well as the drop size distribution. The tests results of emulsions that remain fluid are shown and an example of the microstructure of an emulsion of vacuum residue-in-water is given. As well as an example of histogram of the drop size distribution of an emulsion of vacuum distillation-in-water, and another one of the viscosity in function of temperature at different cut efforts in one emulsion of vacuum distillate residue-in-water.

    Full Text Available It is quite interesting to note that Pidgin which essentially began as a demanded language between the white importers, who later turned colonial masters, and their black traders has now become a campus language-spoken of the majority of the population among the Nigerian students in advanced institutions of learning. Nigerian Pidgin English evolved as a result of language contact with the British colonialists. This study seeks to assess the use, and also determine the recognition of Pidgin English among Nigerian postgraduate students in Universiti Putra Malaysia. Questionnaires were administered on selected students in the university in an attempt to elicit the attitude and usage of the informants to Nigerian Pidgin English. The results were calculated in percentages. It was found that the attitude of Nigerian students regarding the Nigerian Pidgin English in UPM is positive. To conclude, in the next few years, Nigerians are expected to use Nigerian Pidgin English in all situations when they communicate.              Keywords: Pidgin, Nigerian Pidgin English, language contact

  7. Determining the group hydrocarbon composition of oil distillates and residues using highly effective liquid chromatography. 2. A method for determining the calibrating coefficients based on the specific weight of a petroleum product

    Sadas, M.; Yetsuro, N.

    1984-01-01

    The calibrating coefficients (F) for saturated hydrocarbons (Uv) and aromatic hydrocarbons (ArU) proceeding from data based on d 15/4 for the studied petroleum products were identified in order to evaluate the group hydrocarbon composition of petroleum distillates and residues using high resolution liquid chromatography (VEZhKh). The relationship between d 15/4 and deltan (the difference in the refraction index between d 15/4 and n-C6H14) for each type of hydrocarbon was used for this purpose. The relationships between the calibrating coefficients and deltan are studied for solutions of pure hydrocarbons in n-C6H14. (The calibrating coefficients are not proportional to delatn). The effect of the length of the tower and the packing on the relationship between the calibrating coefficients and deltan is also studied. Standard compounds are selected to determine the relationship between the calibrating coefficients and deltan. The relationship is expressed by the formula F = A(1 - Bexp(-Cdeltan)), where A, B and C are constants. Good agreement is observed for the values of the calibrating coefficients calculated by this method and measured by a known method.

    This short communication summarizes a global and continuous reflection on the origins of life. "Prebiotic Petroleum" assumes that " the class of most complex molecules of life that may have geochemical and abiotic origin is the class of fatty acids with long aliphatic chains" and proposes a physical process for the formation of liposomes. Developments following the workshop start from the idea that the liposomes also acquire ion exchange channels physically during their forming process.

    This work presents the technological capacity that, through the years, has been developed in emulsions of heavy oil in water preparations, as well as the potential application that this technology has in the electrical sector and the problem reduction during the extraction and handling of high viscosity heavy oils. Within this technological development it first appears the process for the formation of emulsions of residual petroleum within lots, followed by the preparation of emulsions in a continuous way within a laboratory model, and finally the production in greater scale in a pilot plant, including more and more adequate tense-actives for the formation of emulsions. Also experimental systems are presented to execute static stability and dynamic tests in different conditions, pumping tests for the handling of these emulsions and burning tests for their combustion. All of this with the purpose of consolidating the technology of residual petroleum emulsions as a profitable alternative that replaces the heavy fuel oil and to solve specific problems of the oil industry, among other benefits.

    In exploration and production of petroleum is generated solid waste different and components other. The petroleum oily sludge is a complex mix of components different (water, oil and solid). The petroleum oily sludge generally has other residues and is formed during production and operations, transport, storage and petroleum refining (atmospheric residue, vacuum residue and catalytic cracking residue). However, according to its origin, the compositions can be found quite varied for sludge. Observing the process steps production and refining is possible to locate its main sources and percentage contributions in terms of waste generation. The elemental analysis was performed with oily sludge from region and it showed different composition. For carbon element and hydrogen, small differences was observed, but for was observed greater differences for Oxygen element. The sludge has different inorganic and organic composition. The sludge from oil water separator (OWS) 2 showed a greater amount of oil (94.88%), this may indicate a residue of aggregate high for petroleum industry. In analysis of Saturates, Aromatics, Resins and Asphaltenes (SARA), the sludge from unloading showed amount high of saturates. The inorganic material separated from sludge was characterized and sludge from OWS 2 had high amount sulfur (41.57%). The sludge analyzed showed organic components high values, so it can be treated and reprocessed in process units petroleum industry. The analysis thermal degradation had a better setting for treated oily sludge. (author)

The soil samples were collected from South Sumatra mangrove forest which was contaminated by petroleum. The isolates obtained were selected based on their ability to survive, to grow and to degrade polycyclic aromatic hydrocarbons in medium containing petroleum residue. There were 3 isolates of soil borne hydrocarbonoclastic fungi which were able to degrade petroleum in vitro. The 3 isolates were identified as Aspergillus fumigates, A. parasiticus, and Chrysonilia sitophila. C. sitophila was the best isolate to decrease total petroleum hydrocarbon (TPH from medium containing 5-20% petroleum residue.

    This study comparatively assessed the somatotype characteristics of elite male Nigerian power athletes who comprised middleweight boxers (n = 23), weightlifters (n = 18) and wrestlers (n = 21), as well as a nonathletic group (n = 19). They were aged 24-35 years. Analysis of variance and Scheffe post hoc method were used to determine significant differences in the mean somatotype ratings of the groups. Among the groups, the nonathletes (4.02) were most significantly endomorphic (p less than 0.05). The weightlifters (5.12) and wrestler (5.04) were more significantly mesomorphic (p less than 0.05) than the boxers. (3.18) and nonathletes (3.06). The wrestlers' and weightlifters' dominance in mesomorphy confirms earlier reports on the salience of mesomorphy in performing strength-related skills.

  16. Leadership and the Nigerian Economy

    Directory of Open Access Journals (Sweden)

    Victor E. Dike

    2014-02-01

    Full Text Available The Nigerian economy is largely oil-based. Some people would rather say it is a mono-product economy. The economy has been in dire straits over the years, because of a combination of the neglect of education, especially technical and vocational education and science-based technology education, poor leadership and governance, corruption, as well as poor monetary and fiscal policies. All these have made a review of the poor investment in human capital development and infrastructure and institutions that drive the Nigerian economy and national development rather compelling. The political leaders have always raised the people’s hope by painting glowing pictures of their development plans and how they would stimulate the economy and improve the people’s living conditions. Thus, they swore that they would give priority attention to human capital development and national development, and empower the citizens, particularly the poorly educated, unskilled, and unemployed youths, with relevant human skills capital and entrepreneurial skills to enable them to contribute profoundly to national development. Yet the political leaders have, over the years, failed to adequately fund education and strengthen the infrastructure and institutions that would drive the economy and create employment for the teeming population. Both the new-breed politicians, like the old politicians before them, are promising to transform the nation into an industrialized society and the people cannot hold their expectations. The reality though is that Nigeria cannot become an industrialized society without investing abundantly in human capital development (education and health, leadership, and technological capabilities, which means investing in the future development of the nation.

    2012-10-15

    The purpose of this report is to summarise the findings of the scientific and technical work undertaken by CONCAWE to assess the feasibility and potential benefit of characterising petroleum UVCB substances (Substances of Unknown or Variable Composition, Complex reaction products or Biological Materials) beyond the recommendations issued by CONCAWE for the substance identification of petroleum substances under REACH. REACH is the European Community Regulation on chemicals and their safe use (EC 1907/2006). It deals with the Registration, Evaluation, Authorisation and Restriction of Chemical substances. The report is based on Member Company experience of the chemical analysis of petroleum UVCB substances, including analysis in support of REACH registrations undertaken in 2010. This report is structured into four main sections, namely: Section 1 which provides an introduction to the subject of petroleum UVCB substance identification including the purpose of the report, regulatory requirements, the nature of petroleum UVCB substances, and CONCAWE's guidance to Member Companies and other potential registrants. Section 2 provides a description of the capabilities of each of the analytical techniques described in the REACH Regulation. This section also includes details on the type of analytical information obtained by each technique and an evaluation of what each technique can provide for the characterisation of petroleum UVCB substances. Section 3 provides a series of case studies for six petroleum substance categories (low boiling point naphthas, kerosene, heavy fuel oils, other lubricant base oils, residual aromatic extracts and bitumens) to illustrate the value of the information derived from each analytical procedure, and provide an explanation for why some techniques are not scientifically necessary. Section 4 provides a summary of the conclusions reached from the technical investigations undertaken by CONCAWE Member Companies, and summarising the

    Full Text Available BACKGROUND:The aim of this study is to establish the patterns of death amongst Nigerian leaders since independence, thus providing a feasible avenue to avoid their recurrence if possible especially amongst the political elite who currently hold power. METHODS: Using available unclassified authentic public information, all leaders who had ruled Nigeria since her independence on 1 October, 1960 until her 45th birthday on 1 October 2005, irrespective of whether they are dead or alive were included. Data was extracted and analyzed. RESULTS: On 1 October 2005, Nigeria celebrated 45 years as a sovereign nation. Within this period, the country has had eleven leaders, all of whom were men. Only three (27.3% were civilians, while eight (72.7% were army generals. Of the eleven leaders, four (36.4% had died before Nigeria reached its 45th birthday and all of these four (100% died while still in office. Three of the dead leaders (75% were assassinated, while one (25% died suddenly in mysterious circumstances, believed to be the result of poisoning by unknown external powerful interest groups. Three of the deaths (75% occurred during violent periods of Nigeria’s checkered history (1966-1970 and 1993-1999, showing that periods of national and international strife appeared to be the weakest link in chains of events that led to their death while in office. Autopsies were neither requested nor performed on any of the dead leaders, signifying an entrenched culture of nonchalance, a lack of a coordinated national coroner’s law and contempt for accurate and detailed death records. Worse still, no valid tenable death certificate has ever been issued. In other words, no attempt has been made to determine the cause of death of four of the nation’s former leaders. Only hurried national burials were accorded two (50% of them while the other two (50%, who died in the coup and revenge coup of 1966, were completely neglected, and not even given a decent national

  5. The Challenge of Liquid Transportation Fuels in Nigeria and the Emergence of the Nigerian Automotive Biofuel Programme

    2013-04-01

    Full Text Available This study is aimed at assessing the challenge of liquid transportation fuel in Nigeria, which necessitated the entrance of the country into the biofuel race. The study found that despite being an important member of the organization of petroleum exporting countries (OPEC, Nigeria still suffers from fuel scarcities. Reasons for the short supply of refined petroleum products (particularly gasoline, diesel and aviation fuel in Nigeria include poor capacity utilization of the nation’s refineries, disruption of crude oil supply to the refineries and political instability in the Niger Delta region (Nigeria’s oil province. Nigeria now relies heavily on foreign nations for the supply of these fuels. The country spends substantial part of her foreign exchange on fuel importation. The Federal Government now wishes to reverse this trend by initiating the automotive biofuel programme. The Nigerian automotive biofuel programme involved the construction of 9 plants comprising of 4 sugarcane and 2 cassava bioethanol projects and 3 biodiesel projects. These projects would involve the investment of $1.27 billion into the Nigerian economy for the production of 445 million L of ethanol, 192 MW of green electricity and 120 million L of biodiesel annually

    Full Text Available Some physical and chemical properties of samples of light, medium and heavy Nigerian crude oils and petroleum products including gasoline, kerosene and engine oil have been measured and are reported in this paper. The crude oils and petroleum products have also been characterized by fractional distillation and elution liquid chromatography. The fractions obtained from elution liquid chromatography were analyzed using gas chromatography (GC. The GC fractions were identified by comparing the retention time of peaks in the unknown samples with those of components of calibration standard mixtures. The importance of the physico-chemical properties and the significance of the fractional distillation and chromatographic separation methods to industrial process operations have been discussed.

    Libya has the largest petroleum reserves of any country in Africa and since production began in 1961 over 20 billion barrels of oil have been produced. Libya is scheduled to reach the mid-point of depletion of reserves in 2001 and this provides a timely point at which to review the state of petroleum exploration in Libya. A large amount of data has been published on the geology of Libya, but it is scattered through the literature; much of the older data has been superceded, and several of the key publications, especially those published in Libya, are difficult to find. This book represents the first attempt to produce a comprehensive synthesis of the petroleum geology of Libya. It is based exclusively on published data, supplemented by the author's experience gained during ten years work in Libya. The aim of the book is to systematically review the plate tectonics, structural evolution, stratigraphy, geochemistry, and petroleum systems of Libya, and provides valuable new data on fields, production, and reserves. This volume will provide a ready source of reference to individuals and companies who wish to obtain an overview of the petroleum geology of Libya, and will save them the laborious task of sifting through hundreds of publications to find the data they require. The book includes 148 newly drawn figures.

    Full Text Available http://dx.doi.org/10.5007/2175-8026.2013n65p73 Five decades of resorting to humanistic critical procedureshave bequeathed to the Nigerian critical practice the legacy ofexamining and discovering in Nigerian and African narrativesthe historical and social concepts of the time and times theyare presumed to posit. These concepts include colonialism,corruption, war, political instability, and culture conflict. Theseprocedures are undertaken without due regard to seeing the wholeof the literary tradition as a stream out of which narratives emerge.This article, therefore, by way of introduction, seeks to retrieveNigerian narratives from “every author” and humanistic criticalapproach by placing them in a realm where a holistic method suchas Frye’s could be applied. Here, the traverses of the structure ofmythical imagery such as the mythos of crime and punishmentas embodied in these narratives and how this structure wasdisplaced/shrouded from Frye’s first mimetic mode to the last, viathe concept of mythic displacement, will be analysed.

    1988-09-01

    As the economy of Libya is, like other OPEC countries, greatly dependent on petroleum, its account is now in the red owing to the recent decrease of petroleum income. Petroleum development in Libya was started in 1955, and more than 3 million barrels of petroleum came to be produced per day in 1970 thanks to the light and low-sulfur quality of the petroleum. As a result of the nationalizing policy of petroleum undertakings after the revolution, the government's participation rate became 60.7% in 1974. The USA began sanction on Libya in 1981 and the export to the USA decreased suddenly, but Libya maintained the export amount of 1 million barrels per day with the exports to Western Europe and with flexible export policies. These flexible policies, in a way, accelerated the adverse development in the market and caused the decrease of petroleum income. The constructions of petroleum factories have been postponed or stopped because of the low petroleum income, and the recent export amount of manufactured petroleum is only about 130,000 barrels per day. libya is, therefore, to push the diversification of undertakings and to develop gas resources and the like in the future. In connection with the diversification of undertakings, Libya is actively pushing into the foreign petroleum markets and joining hands with foreign petroleum companies. (6 figs, 8 tabs)

    The four chapters that are described in this report cover a variety of subjects that not only give insight into the understanding of multiphase flow in fractured porous media, but they provide also major contribution towards the understanding of flow processes with in-situ phase formation. In the following, a summary of all the chapters will be provided. Chapter I addresses issues related to water injection in water-wet fractured porous media. There are two parts in this chapter. Part I covers extensive set of measurements for water injection in water-wet fractured porous media. Both single matrix block and multiple matrix blocks tests are covered. There are two major findings from these experiments: (1) co-current imbibition can be more efficient than counter-current imbibition due to lower residual oil saturation and higher oil mobility, and (2) tight fractured porous media can be more efficient than a permeable porous media when subjected to water injection. These findings are directly related to the type of tests one can perform in the laboratory and to decide on the fate of water injection in fractured reservoirs. Part II of Chapter I presents modeling of water injection in water-wet fractured media by modifying the Buckley-Leverett Theory. A major element of the new model is the multiplication of the transfer flux by the fractured saturation with a power of 1/2. This simple model can account for both co-current and counter-current imbibition and computationally it is very efficient. It can be orders of magnitude faster than a conventional dual-porosity model. Part II also presents the results of water injection tests in very tight rocks of some 0.01 md permeability. Oil recovery from water imbibition tests from such at tight rock can be as high as 25 percent. Chapter II discusses solution gas-drive for cold production from heavy-oil reservoirs. The impetus for this work is the study of new gas phase formation from in-situ process which can be significantly

    Juvenile dermatomyositis is an autoimmune connective tissue disease occurring in children less than 16 years old. It is part of a heterogeneous group of muscle diseases called idiopathic Iiflammatory myopathies. It had previously been reported in black Africans resident in UK. However, there is no documented case reported from Africa. The index sign of heliotrope rashes is often difficult to visualise in the black skin. An 11-year-old Nigerian girl presenting with clinical, laboratory and histopathological features of juvenile dermatomyositis is presented here. It is hoped that this case will heighten the index of suspicion of this condition among medical practitioners in Africa. PMID:24706700

The investigation conducted reveals a weak connectivity in the set of official websites of Nigerian universities. However, the connectivity becomes stronger when all the university websites are taken into account. It increases significantly with the addition of the only found web communicator to the university websites -- National Universities Commission -- the sole body that approves the establishment of higher educational institutions in Nigeria and all academic programmes run by them.

    Advances in interpretive and analytical methods have opened the possibility to improve the existing Nordtest methodology for oil spill identification which was developed in 1991 under the Nordic Council of Ministers. In 2002, the European Committee for Standardization (CEN) established 2 working groups to revise the Nordtest Methodology into the following 2 CEN guidelines: (1) oil spill identification which includes waterborne and petroleum products, and (2) oil spill identification which in addition to including waterborne petroleum and petroleum products, includes analytical methodology and interpretation of results. The revised methodology includes a protocol/decision chart that has 3 tiered levels of analyses and data treatment. The methodology relies on the characterization of diagnostic ratios. The CEN working group intends to use the guidelines as a basis for a national oil spill identification protocol in each European country and for further international use. The methodology can be applied to oil samples of petrogenic origin with boiling points above 200 degrees C, such as crude oils, diesel fuel oils, residual bunker oils, lubricants, and mixtures of oily bilge and sludge samples. It is not intended for automotive gasolines or other light petroleum products. The method has been implemented in most forensic laboratories in Europe and has successfully differentiated between oils from a spill and possible pollution sources. 19 refs., 4 tabs., 10 figs.

    This article presents a study of the efficiency and degradation pattern of samples of petroleum sludge and polluted sandy soil from an oil refinery. A bacterial consortium, consisting of strains from the genera Pseudomonas, Achromobacter, Bacillus and Micromonospora, was isolated from a petroleum sludge sample and characterized. The addition of nitrogen and phosphorus nutrients and a chemical surfactant to both the samples and bioaugmentation to the soil sample were applied under laboratory conditions. The extent of biodegradation was monitored by the gravimetric method and analysis of the residual oil by gas chromatography. Over a 12-week experiment, the achieved degree of TPH (total petroleum hydrocarbon) degradation amounted to 82-88% in the petroleum sludge and 86-91% in the polluted soil. Gas chromatography-mass spectrometry was utilized to determine the biodegradability and degradation rates of n-alkanes, isoprenoids, steranes, diasteranes and terpanes. Complete degradation of the n-alkanes and isoprenoids fractions occurred in both the samples. In addition, the intensities of the peaks corresponding to tricyclic terpenes and homohopanes were decreased, while significant changes were also observed in the distribution of diasteranes and steranes.

  4. EVALUATION OF BIODEGRADATION IN THE SOIL OF OIL RESIDUES FROM A PETROLEUM REFINARY = AVALIAÇÃO DA BIODEGRADAÇÃO NO SOLO DE RESÍDUOS GERADOS EM REFINARIA DE PETRÓLEO

    Full Text Available Innumerable types of treatment systems exist to promote the degradation of oil residues. One of the best known and most used systems is landfarming, which consists of the aerobic biodegradation of residues that are applied in the soil and incorporated into the superficial layers. The process of landfarming uses the activityof the microorganisms in the soil to degrade and/or to immobilize many components of the residues. This study was developed in the Superior Center for Technological Education - CESET/UNICAMP, with the objective of verifying the biodegradation of oily dregs resulting from the oil refinery process, and the biological sludge that results from the industrial effluent treatment process of the Refinery of Paulínia, SP, in landfarming soil. Through the analysis of the results obtained, it was verified that when oily dregs were added to the soil, the biodegradation was more efficient. Applying only thebiological sludge in the same rate as the oily dregs, the breathing that was caused by the biodegradation did not undergo quantitative differences. Mixing the application of oily dregs and biological sludge in a ratio of 1:1, an improvement was observed in the breathing efficiency, however this did not surpass that emitted by the ground when only the oily dregs were applied. It was concludedthat the landfarming system has indigenous microorganisms able to degrade several compounds existing in the residues of oil refinery. To improve the efficiency of the biodegradation, the rate of application of the residues in the ground is a limiting factor. = Existem inúmeros tipos de sistemas de tratamento para promover a degradação dos resíduos de petróleo. Entre os mais conhecidos e utilizados destaca-se o “landfarming”, que consiste na biodegradação aeróbia de resíduos que são aplicados no solo e incorporados nas camadas superficiais.

    Double-crested cormorants (Phalacrocorax auritus ) collected in the Houston Ship Channel, Texas, USA, in November shortly after their fall migration contained residues of several industrial, agricultural, and petroleum contaminants including polychlorinated styrenes (PCS's), polychlorinated biphenyls (PCB's), DDE, and petroleum hydrocarbons. PCS concentrations in over-wintering birds collected in late February were three times higher than those in birds collected in November. PCB and petroleum concentrations remained at about the same level throughout the 3-month winter period. Petroleum hydrocarbons were present in all cormorants and residues in some individuals exceeded 25 ppm (wet weight). Mean DDE residues in samples collected in November and February were less than 1 ppm. Low concentrations of five other organochlorine compounds, not detected in cormorants collected in November, were recovered in birds collected in February.

    Petroleum hydrocarbon pollutants are recalcitrant compounds and are classified as priority pollutants. Cleaning up of these pollutants from environment is a real world problem. Bioremediation has become a major method employed in restoration of petroleum hydrocarbon polluted environments that makes use of natural microbial biodegradation activity. Petroleum hydrocarbons utilizing microorganisms are ubiquitously distributed in environment. They naturally biodegrade pollutants and thereby remove them from the environment. Removal of petroleum hydrocarbon pollutants from environment by applying oleophilic microorganisms (individual isolate/consortium of microorganisms) is ecofriendly and economic. Microbial biodegradation of petroleum hydrocarbon pollutants employs the enzyme catalytic activities of microorganisms to enhance the rate of pollutants degradation. This article provides an overview about bioremediation for petroleum hydrocarbon pollutants. It also includes explanation about hydrocarbon metabolism in microorganisms with a special focus on new insights obtained during past couple of years. Copyright © 2016 Elsevier Ltd.

    Full Text Available Organizational management are concerned with the effect of both radical and sudden changes can have on individual relationship with the organization and the organization as a whole. In line with this, the study attempt to assess employees’ perception of change management in Nigerian universities by investigating the relationship between change management and employee commitment on one hand, success and failure of change initiatives and employees’ readiness and resistance to change initiatives on the other hand respectively. 180 questionnaires were administered to employees of three universities in south west region of Nigeria. Data obtained was analysed using descriptive statistics while hypotheses were tested using correlation and regression analysis. The result of the findings revealed a strong and direct relationship between change management and employee commitment, success and failure of change programmes has a positive and significant relationship with employee readiness and resistance to change respectively in Nigerian universities. This paper therefore make useful recommendations to universities and other organisations among which include although, employee might resist change, organization should try their best to properly manage the resistance as it can be beneficial to the employees and the educational organizations at large.

The research question that the research tries to address is: to what extent are the leadership styles expressed in modern management theories consistent with Nigerian Traditional values? The findings do confirm that the perceived leadership style in the organizations by the managers is autocratic, the preferred style is the paternalistic and the rejected is the autocratic. For about one in five Nigerian managers, the democratic style is the most often rejected. The study challenges the validity of dominant Western universal perspectives in managerial leadership in traditional African organizations.

  3. Geoscience indexing at petroleum abstracts

    Energy Technology Data Exchange (ETDEWEB)

    Finnegan, M.A.

    1985-01-01

    Geoscience literature received by Petroleum Abstracts Information System is indexed by Scientist with field experience. The indexing consists of relating concepts produced by the author to a controlled vocabulary used at Petroleum Abstracts. The primary emphasis of selection of the literature at Petroleum Abstracts is petroleum-related, but not petroleum restricted. Geoscience literature indexed at Petroleum Abstracts comprises the following subjects: Geology, Geochemistry, Geophysics, and Mineral Commodities. The depth of indexing attributed to each article does in fact depend on the amount of petroleum-related subject matter in the article. Once the indexing is completed, the abstract is then cut to approximately 150 words. The scientist who indexes at Petroleum Abstracts is not expected to know or remember every detail or concept ever published. But he or she is expected to be able to go to an atlas, dictionary, or any other reference material available and apply the concepts to a controlled vocabulary. This is somewhat of a restriction on scientists, but it is the only way to maintain any kind of consistency in the indexing. Successful searching of the Petroleum Abstracts Information System can be accomplished with an understanding of the indexing strategy and the importance and necessity of referencing the thesauri controlled vocabulary. It may be more time-consuming, but will certainly be more accurate in the retrieval of the information.

    Full Text Available Orientation: Identification of tourists’ needs and finding ways of satisfying them is crucial to any tourism destination.Research purpose: This paper investigated the challenges, demands and expectations of Nigerian tourists to South Africa.Motivation for the study: Nigeria, along with other African nations, has been identified as one of the core regional source markets with air links to South Africa. Increasing revenue generated from regional tourism is important to South African Tourism.Research design, approach and method: Descriptive statistics and Chi-square tests were used to analyse the data collected using a questionnaire survey of 320 Nigerian tourists to South Africa.Main findings: Results showed that Nigerian tourists visit South Africa mostly for the purposes of business, holiday, visiting friends and relatives, education and medical care. Challenges perceived by these Nigerian tourists visiting South Africa include long waiting time for the visa process in Nigeria, expensive cost of living in South Africa, safety and security problems, not so many airlines to choose from and expensive flight costs. Nigerian tourists mostly expect South Africans to be friendlier and have expectations of linking up with new business partners or performing transactions. They also have a strong demand for shopping, leisure and quality education.Practical/managerial implications: This study recommends a bilateral tourism relationship agreement between the Nigerian and South African governments to ameliorate the visa process; targeted marketing communications by South African Tourism toward Nigerian tourists based on study results; strong police presence and proper policing in South Africa; air transport liberalisation and low-cost carriers implementation for shared economic growth within the African region.Contribution/value-add: No former research has specifically identified Nigerian tourists’ challenges, expectations and demands whilst visiting

Based on available well data, the rifting probably began in the Cretaceous time had continued until Paleocene. It is considered that compressional force immediately after rifting event deformed sedimentary sections. During the period of Paleocene to middle Miocene, the sediments were deposited in stable environment without particular tectonic event. 2) Petroliferous basin analysis in Taegu area (II): The Nakdong and Jinju formations contain abundant black shales, and thermal maturity of the organic matter reached at the final stage of dry gas generation. These formations also contain thick sandstones which can act as a petroleum reservoir. However, reservoir quality of the sandstones is poor (porosity: < 5%; permeability: < 0.001 md). In these sandstones, secondary pores such as dissolution pores and micropores can act as a tight gas reservoir. (author). 56 refs., 24 tabs., 68 figs.

  15. Genetic classification of petroleum basins

    Energy Technology Data Exchange (ETDEWEB)

    Demaison, G.; Huizinga, B.J.

    1989-03-01

    Rather than relying on a descriptive geologic approach, this genetic classification is based on the universal laws that control processes of petroleum formation, migration, and entrapment. Petroleum basins or systems are defined as dynamic petroleum-generating and concentrating physico-chemical systems functioning on a geologic space and time scale. A petroleum system results from the combination of a generative subsystem (or hydrocarbon kitchen), essentially controlled by chemical processes, and a migration-entrapment subsystem, controlled by physical processes. The generative subsystem provides a certain supply of petroleum to the basin during a given geologic time span. The migration-entrapment subsystem receives petroleum and distributes it in a manner that can lead either to dispersion and loss or to concentration of the regional charge into economic accumulations. The authors classification scheme for petroleum basins rests on a simple working nomenclature consisting of the following qualifiers: (1) charge factor: undercharged, normally charged, or supercharged, (2) migration drainage factor: vertically drained or laterally drained, and (3) entrapment factor: low impedance or high impedance. Examples chosen from an extensive roster of documented petroleum basins are reviewed to explain the proposed classification.

    Sexual assault is a common social disorder among students in our tertiary institutions. This study ascertains the extent and effect of sexual assault among Nigerian students. Two hundred and Sixty Eight structured questionnaires were distributed to randomly selected students in 4 tertiary institutions, information on socio demography, sexual history and consequences of their exposure were obtained for analysis and interpretation. Thirty seven (13.8%) of the respondents were sexually assaulted as a student and 19 (7.1%) were assaulted by their lecturers and fellow students, Younger age at coitarche, history of forced coitarche, marriage, coitarche with relations and unknown persons, significantly influenced subsequent risks of sexual assault. Improve security, moral behaviours enforcing dress code and stiffer penalties were suggested ways to prevent sexual assault among the students. Sexual assault is still a common finding in our institutions; effort should be made by all stake holders to prevent this social embarrassment.

    The uses of herbal products are not regulated in Nigeria and in many low-income countries and are freely available to everyone. The safety of these herbal medicines is poorly understood. This study characterizes the content of cadmium, copper, iron, nickel, selenium, zinc, lead and mercury in a random sample of Nigerian traditional products. Ready-to-use herbal products were purchased from the open market and digested using HNO{sub 3}.The heavy metal content of the digested filtrate was determined by atomic absorption spectrometry Uni-cam Model 929. The result showed that 100% of the samples contained elevated amounts of heavy metals. These data alert us to the possibility of heavy metal toxicity from herbal products in Nigeria. The public health hazards from ingestion of herbal medicines should be identified and disclosed by in-depth risk assessment studies.

Methods: This study was a retrospective study looking at those records of individuals who had undergone specular microscopy or corneal endothelial cell count measurement at the MeCure Eye Center. Results: The endothelial cell characteristics of 359 healthy eyes of 201 volunteers were studied. The mean corneal endothelial cell density (MCD was 2,610.26±371.87 cells/mm2 (range, 1,484–3,571 cells/mm2. The MCD decreased from 2,860.70 cells/mm2 in the 20–30-year age group to 2,493.06 cells/mm2 in the >70-year age group, and there was a statistically significant relationship between age and MCD with a P-value of <0.001. There was no statistically significant correlation between sex and corneal endothelial cell density (P=0.45. Conclusion: This study shows that endothelial cell density in Nigerian eyes is less than that reported in the Japanese, American, and Chinese eyes, and is comparable to that seen in Indian and Malaysian eyes.

  2. Language Preference among Nigerian Undergraduates and the Future of English

    Full Text Available What will be the future of English in Nigeria? Put more apprehensively, will the English language die in Nigeria in the near future? These questions are answered by reporting on the language preference at home of some Nigerian undergraduates in order to gauge the future of English in Nigeria. The investigation sought to determine the language(s most preferred for communication at home among Nigerian undergraduates. From a sample drawn from students in a private Nigerian university, 66.7% identified English as the most frequently used language at home while 64.1% indicated fluency in English against other languages spoken in Nigeria including the indigenous major Nigerian languages (Hausa, Igbo and Yoruba. On order of fluency among the languages sampled, 18.5% indicated an English-only fluency, which reveals that some section of young Nigerians are moving towards a monolingual English-only proficiency. This discovery has implications for the future of English in Nigeria. Several factors may account for this emerging trend. However, the premier position occupied by English in Nigeria and the expanding use of English world-wide clearly support the continuous growth and visibility of English as the language of choice among Nigerian undergraduates at home. This is without prejudice to several declarations and policy statements in favour of Mother Tongue education and usage in Nigeria. The paper concludes that the emergence of a new generation of Nigerians who use English as a first language in a non-host second language context is sowing the seed for further nativization and entrenchment of English in Nigeria.

A cross-sectional, multi-center survey of Nigerian pharmacy students from 7 schools of pharmacy was conducted using 2 validated questionnaires measuring cognitive constructs such as test anxiety, academic competence, test competence, time management, and strategic study habits. Results. Female students and older students scored significantly better on time management skills and study habits, respectively. Test anxiety was negatively associated with academic performance while test competence, academic competence, and time management were positively associated with academic performance. These 4 constructs significantly discriminated between the lower and higher performing students, with the first 2 contributing to the most differences. Conclusion. Test and academic competence, test anxiety, and time management were significant factors associated with low and high academic performance among Nigerian pharmacy students. The study also demonstrated the significant effects of age, gender, and marital status on these constructs.

    Full Text Available Since the past two decades or so the question of functionality of Nigerian educational products has been an issue of concern and a subject of discussion among educational analysts. This is against the backdrop that many students who graduate with admirable certificates from the nations reputable institutions are often unable to apply the acquired knowledge and skills to work situations. Contemporary societies all over the world require that preparation for work must become an integral part of a persons total educational experience. One reason for this requirement is to equip their citizenry with employable skills to enable them produce and use the goods and services which any society needs for its socio-economic growth. This paper therefore examines the role of skill acquisition in the transformation of Nigerian economy and proffers suggestions on how it can be repositioned to transform Nigerian education.

    Our aim was to assess the basic musculoskeletal competency of pre-internship graduates from Nigerian medical schools. We administered the Freedman and Bernstein basic musculoskeletal competency examination to 113 pre-internship graduates from seven Nigerian medical schools over a three year period from 2008 to 2010 at the University of Uyo Teaching Hospital. Five specialist residents took the examination to test criteria relevance. All graduates failed this test, obtaining scores ranging from 7% to 67%. The duration of the orthopaedic posting, and observation of operative fracture fixation, were not significant determinants of the score. The two final-year specialist residents each had a marginal pass in the examination. Basic musculoskeletal competency among pre-internship Nigerian medical-school graduates is inadequate.

  14. Speaking denunciation: satire as confrontation language in contemporary Nigerian poetry

    Directory of Open Access Journals (Sweden)

    Akingbe, Niyi

    2014-07-01

    Full Text Available Contemporary Nigerian poets have had to contend with the social and political problems besetting Nigeria’s landscape by using satire as a suitable medium, to distil the presentation and portrayal of these social malaises in their linguistic disposition. Arguably, contemporary Nigerian poets, in an attempt to criticize social ills, have unobtrusively evinced a mastery of language patterns that have made their poetry not only inviting but easy to read. This epochal approach in the crafting of poetry has significantly evoked an inimitable sense of humour which endears these poems to the readers. In this regard, the selected poems in this paper are crowded with anecdotes, the effusive use of humour, suspense and curiosity. The over-arching argument of the paper is that satire is grounded in the poetics of contemporary Nigerian poetry in order to criticize certain aspects of the social ills plaguing Nigerian society. The paper will further examine how satire articulates social issues in the works of contemporary Nigerian poets, including Niyi Osundare, Tanure Ojaide, Chinweizu, Femi Fatoba, Odia Ofeimun, Ezenwa Ohaeto, Obiora Udechukwu and Ogaga Ifowodo. Viewed in the light of artistic commitment, the paper will demonstrate how satire accentuates the role of these poets as the synthesizers/conduits of social and cultural concerns of Nigerian society for which they claim to speak. As representatively exemplified in the selected poems, the paper will essentially focus on the mediation of satire for the impassioned criticism of social and moral vices, militating against Nigeria’s socio-political development.

    Recent discoveries and important oil shows have proven the existence of hydrocarbons in newly identified depocenters and reservoirs. In general, except for some areas around the producing fields, Tunisia is largely underdrilled. The national company ETAP has decided to release data and to publish a synthesis on the petroleum geology of Tunisia. The geology of Tunisia provides a fine example of the contrast between Alpine folding, which typifies northern Tunisia and the African craton area of the Saharan part. Eastern Tunisia corresponds to an unstable platform forming plains or low hills and extending eastwards to the shallow Pelagian Sea. There are a wide variety of basins: central and northern Tunisia represents a front basin the Saharan Ghadames basin or the Chott trough are sag basins; the Gulf of Gabes was formed as a distension margin the Gulf of Hammamet is a composite basin and several transversal grabens cut across the country, including offshore, and are rift-type basins. All these features are known to be oil prolific throughout the world. Two large fields and many modest-size pools are known in Tunisia. Oil and gas fields in the surrounding countries, namely the Saharan fields of Algeria and Libya the large Bouri field offshore Tripolitania and discoveries in the Italian part of the Straits of Sicily, suggest a corresponding potential in Tunisia. Exposed paleogeographic and structural maps, balanced sections, and examples of fields and traps will support an optimistic evaluation of the future oil exploration in Tunisia.

    Pregnancy results in a lot of hormonal changes in the body and the eyes are no exception. These ocular changes could be physiologic, pathologic or a modification of a pre-existing condition. The aim of this study was to determine physiologic ocular changes that are associated with pregnancy in healthy Nigerian women. A total of 100 women were followed longitudinally through out the course of their pregnancy and 6 weeks postpartum. The women were recruited at 8 weeks of pregnancy at the anti-natal clinic in the Department of Obstetrics and Gynecology, University of Benin Teaching Hospital, Nigeria. The women were aged between 20 and 35 years. Tests carried out included visual acuity, ophthalmoscopy, retinoscopy, and tonometry. The tests were carried out in each of the three trimesters of pregnancy and 6 weeks postpartum. There was a fall in intraocular pressure across the trimesters and this was very significant (Pchanges associated with pregnancy are transient and most tend to resolve postpartum, with values returning to near pre-pregnant state.

    Full Text Available Petroleum has been and still remains, in equal measure, a friend and an enemy to humanity: a friend for its use in numerous applications over the years, from the lubrication of cart axles to jet fuel; an enemy for creating permanent conflicts between countries, leading to a global conflagration. This layout has perpetuated for over two millennia, until today.The problem of petroleum has a multitude of aspects: economic, political, financial, social, military, legislative and, last but not least, scientific and technical. It has taken a share of sacrifices, which may not be overlooked, to be rightfully called “black gold.” Subject to continuous development, petroleum is still indispensable to our quotidian life, although attempts have been made to replace it with alternative energy sources due to its negative effects on the planet, which are increasingly visible.The present state of petroleum industry is the result of a continuous labor of many generations of researchers, professors, engineers, technicians, foremen, and workers, especially from petroleum producing countries.  Romania is one of the first petroleum producers and ranked first in Europe and among the first nations worldwide until the end of the 19th century.  During the 20th century, a large number of oil and gas reservoirs were discovered in many countries on all continents; even today Romania still remains an important producer with encouraging perspectives.Romanian contributions to the progress of petroleum industry are noticeable, being appreciated and implemented by the major companies worldwide.  This work intends to present just several of these contributions, some of which are highlighted and highly regarded.

    This report consists of 2 subjects. 1) Petroleum resources assessment of the Kunsan Basin : Kunsan Basin is mainly filled with Cretaceous and Tertiary clastic sediments, and divided into Southwest Sub-basin, Central Sub-basin and Northeast Sub-basin by uplifts and faults developed in the basin. Microfossils were studied for the biostratigraphic works of drill wells in the Kunsan Basin. The microfossils include organic-walled microfossils such as spores, pollen and nonmarine dinoflagellates and calcareous microfossils such as ostracods, charophytes and gastropods. The fossil assemblages of the Kunsan Basin reveal nonmarine environments ranging from alluvial fan to shallow lacustrine and climatic variation between subtropical and cool temperate temperature in the arid/humid alternating conditions. According to the paleontological data, the Kunsan Basin was initiated in the Early Cretaceous and expanded during Paleogene followed by regional erosion at the closing time of Paleogene on which Neogene sediments have been accumulated. The Paleogene strata show laterally irregular thickness in each Epoch due to migrating depocenter. 2) Petroliferous basin analysis in Hapcheon area (I) : The Cretaceous Gyeongsang Supergroup consists of more than 9 Km sequences of sedimentary and volcanic rocks in Hapcheon-Changyong-Euiryong-Haman area and occupies the middle part of the Milyang subbasin. The Supergroup can be divided into three group; Sindong, Hayang and Yuchon groups in ascending order. Based on rock color, the Sindong Group can be subdivided into Nakdong, Hasandong and Jinju Formations. The Hayang Group can be subdivided into Chilgok, Silla Conglomerate, Haman and Jindong Formations. The Chilgok Formation includes basaltic lava and tuffs in the upper part. The Haman Formation has Kusandong tuff (keybed) in the uppermost part in the Changyong area, whereas the tuff is intercalated below the vocaniclastics in the Haman area.

    On the basis of diverse microfossils such as foraminifers, ostracods, micromulluscs, fossil spores and pollen and calcareous nannofossils derived from 14 drill holes, the sediments are divided into two part, the upper marine part and the lower nonmarine one. Marine part is subdivided into 4 foraminiferal zones and 3 nannofossil zones of Plio-Pleistocene age. In the lower part ranging from Oligocene to Late Miocene 4 palynomoph assemblages are established, which reflect climatic changes fluctuating between subtropical and cool temperate. Some fine sediments occurring in the South Sea continental shelf are rich in organic matter to be hydrocarbon source rock. The organic matter is mainly compared to type 3. However, lower part of the Geobuk-1 and Okdom-1 shows more oil prone geochemical characteristics than other wells. The kerosene is mixture type 1 and type 3 organic matter. The main oil generation zone located between 2,500 m and 3,000 m and gas generation zone from 3,500 m to 4,000 m approximately. Hydrocarbon accumulation could be expected in the trap formed in the period earlier than 10 Ma. as the hydrocarbon started to be expelled at 10 Ma. according to the modeling. Approximately 13,000 Line-km of multichannel seismic data integrated with 14 wells and gravity and magnetic data were analyzed to investigate the structural and stratigraphic evolution of southern part of offshore Korea. The northeast-southwest trending Taiwan-Sinzi Uplift Belt separates the area into two regions with different tectonic features, northwestern and southwestern regions. The potential hydrocarbon traps associated with anticline, tilted fault block, fault, unconformity, and rollover structure exist.

  4. Genetic classification of petroleum systems

    Huizinga, B.J. (Chevron Oil Field Research Co., Richmond, CA (United States)); Demaison, G.

    1991-03-01

    The authors genetic classification of petroleum basins is founded on a working nomenclature that consists of combining qualifiers from each of the following three categories: (1) the charge factor (supercharged, normally charged, or undercharged), (2) the migration drainage style (vertically drained or laterally drained), and (3) the entrapment style (high impedance or low impedance). The charge factor is estimated on the basis of the richness and volumetrics of mature source rocks. The source potential index (SPI), which combines source-rock richness and thickness into a single parameter, is a convenient shortcut for comparing the petroleum potential of different source rocks containing dissimilar kerogen types and for rapidly estimating a basin's regional charging capacity. On a global scale, a general correlation exists between the magnitude of SPI and basinwide petroleum reserves. The dominant migration drainage style can be predicted from the structural and stratigraphic framework of a basin. Recognition of the dominant migration style helps to predict the location of zones of petroleum occurrence in relation to the 'hydrocarbon kitchens.' The entrapment style, which is also dependent on the structural framework and the presence of seals, describes the degree of resistance (i.e. impedance) working against dispersion of the petroleum charge. Application of these working concepts should help significantly reduce geologic risk, particularly in new ventures-type exploration.

Prevalence of intimate partner violence after HIV diagnosis. Among the women interviewed, 423 (65.8%) reported abuse. In 74.0% of abused women, the abuse started after HIV diagnosis. Though having a HIV negative spouse and disclosure of HIV status were associated with abuse, only having a HIV negative partner retained its association with IPV (OR 3.1; CI 2.4-5.3) after controlling for confounding variables. Sixty-two (9.6%) women have not disclosed their HIV status because of fear of rejection. Verbal abuse (51.7%), threat of violence in 97 (22.9%) and sexual deprivation in 91 (21.5%) were the common forms of abuse reported. IPV is common among HIV positive pregnant Nigerians; with a threefold increased risk in women in HIV serodiscordant relationship.

    2014-05-01

    Full Text Available Written English is one area in which Nigerian linguists and grammarians do not accommodate variations of spelling for any sociolinguistic reason, even though they at times misspell or forget the spelling of some confusing words. Most people agree that English spelling system is problematic and therefore needs urgent reform, but who bells the cat? This article examines the English spelling system against the backdrop of Educated Nigerian English and the concept of nativization, stressing the need for reform or nativized spelling in Nigerian English. Questionnaires, library research, and the Internet were used to gather data for this study. The qualitative approach has been adopted in the main for the interpretation of data. The educated Nigerians studied admit that the English spelling system is in part so confusing that they misspell words at times. Therefore, they support the reform or nativization of English spelling. Consequently, this article presents and illustrates proposed reformed spelling by deleting redundant letters, unnecessary clusters of letters, dropping useless silent letters, regularizing digraph, and spelling compound words in one form only. These changes will enhance spelling skills, teaching, reading, and writing in English as a Second Language.

    Full Text Available In this article, we examine the extant language policies, with particular regard to the Nigerian Child. We take a profound look at the  National Policy on Education 1977, the UNICEF Annual Report 1995, the National Policy on Education 1998, the National Policy on Education 2004, the National Policy for Integrated Early Childhood Development in Nigeria 2007, the United Nations Millennium Development Goals, the Nigeria Millennium Development Goals Report 2010, etc. We seek to appraise the strengths and weaknesses of these policies in order to determine the extent to which they are beneficial to the Nigerian child in the context of plurilingualism and globalization. This appraisal is done employing a tridimensional framework: hindsight, insight and foresight perspectives. We argue for the reconfiguration of language education aimed at functional plurilingualism for the Nigerian child. Recommendations are made in view of enhancing the prospects of functional plurilingualism for every Nigerian child, who will consequently be competent to contribute meaningfully towards the development of Nigeria in particular and mankind in general.

    Full Text Available The current research aimed at collating the views of medical specialists on disease priorities, class and outcomes of health research in Nigeria, and draw appropriate policy implications. Structured questionnaires were distributed to consent 90 randomly selected medical specialists practising in six Nigerian tertiary health institutions. Participants' background information, relative disease priority, research types and class, type and class of publication media, frequency of publications, challenges faced in publishing research, impact of their research on health practice or policy, and inventions made were probed. Fifty-one out of the 90 questionnaires distributed were returned giving a response rate of 63.3%. Sixty-four point six percent indicated that the highest priority should be given to non communicable diseases while still recognizing that considerations should be giving to the others. They were largely “always” involved in simple low budget retrospective studies or cross-sectional and medical education studies (67.8% and over a third (37.5% had never been involved in clinical trials. They largely preferred to “always” publish in PubMed indexed journals that are foreign-based (65.0%. They also indicated that their research works very rarely resulted in inventions (4% and change (4% in clinical practice or health policy. Our study respondents indicated that they were largely involved in simple low budget research works that rarely had significant impacts and outcomes. We recommend that adequate resources and research infrastructures particularly funding be made available to medical specialists in Nigeria. Both undergraduate and postgraduate medical education in Nigeria should emphasize research training in their curricula.

  11. Febrile illness experience among Nigerian nomads

    2012-01-01

    Full Text Available Abstract Background An understanding of the febrile illness experience of Nigerian nomadic Fulani is necessary for developing an appropriate strategy for extending malaria intervention services to them. An exploratory study of their malaria illness experience was carried out in Northern Nigeria preparatory to promoting malaria intervention among them. Methods Ethnographic tools including interviews, group discussions, informal conversations and living-in-camp observations were used for collecting information on local knowledge, perceived cause, severity and health seeking behaviour of nomadic Fulani in their dry season camps at the Gongola-Benue valley in Northeastern Nigeria. Results Nomadic Fulani regarded pabboje (a type of "fever" that is distinct from other fevers because it "comes today, goes tomorrow, returns the next" as their commonest health problem. Pabboje is associated with early rains, ripening corn and brightly coloured flora. Pabboje is inherent in all nomadic Fulani for which treatment is therefore unnecessary despite its interference with performance of duty such as herding. Traditional medicines are used to reduce the severity, and rituals carried out to make it permanently inactive or to divert its recurrence. Although modern antimalaria may make the severity of subsequent pabboje episodes worse, nomads seek treatment in private health facilities against fevers that are persistent using antimalarial medicines. The consent of the household head was essential for a sick child to be treated outside the camp. The most important issues in health service utilization among nomads are the belief that fever is a Fulani illness that needs no cure until a particular period, preference for private medicine vendors and the avoidance of health facilities. Conclusions Understanding nomadic Fulani beliefs about pabboje is useful for planning an acceptable community participatory fever management among them.

  12. Biological Remediation of Petroleum Contaminants

    Kuhad, Ramesh Chander; Gupta, Rishi

    Large volumes of hazardous wastes are generated in the form of oily sludges and contaminated soils during crude oil transportation and processing. Although many physical, chemical and biological treatment technologies are available for petroleum contaminants petroleum contaminants in soil, biological methods have been considered the most cost-effective. Practical biological remediation methods typically involve direct use of the microbes naturally occurring in the contaminated environment and/or cultured indigenous or modified microorganisms. Environmental and nutritional factors, including the properties of the soil, the chemical structure of the hydrocarbon(s), oxygen, water, nutrient availability, pH, temperature, and contaminant bioavailability, can significantly affect the rate and the extent of hydrocarbon biodegradation hydrocarbon biodegradation by microorganisms in contaminated soils. This chapter concisely discusses the major aspects of bioremediation of petroleum contaminants.

    2004-01-01

    On the basis of site investigation and sample collection of petroleum contaminants in the soil-water-crop system in the Shenyang-Fushun sewage irrigation area, the physical-chemical-biological compositions of the unsaturated zone is analyzed systematically in this paper. At the same time, the degradation kinetics of residual and aqueous oils is determined through biodegradation tests. The studies show that dominant microorganisms have been formed in the soils after long-term sewage irrigation. The microorganisms mainly include bacteria, and a few of fungus and actinomycetes.After a 110-days' biodegradation test, the degradation rate of residual oil is 9.74%-10.63%, while the degradation rate of aqueous oil reaches 62.43%. This indicates that the degradation rate of low-carbon aqueous oil is higher than that of highcarbon residual oil. In addition, although microbial degradation of petroleum contaminants in soils is suitable to the firstorder kinetics equation, the half-lives of aqueous oil, No. 20 heavy diesel and residual oil in the surface soils (L2-1, S1-1 and X1-1) are 1732 h, 3465 h and 17325 h, respectively.

    Maternal exposure to ambient air pollution affects placental growth markers. Investigate impact of household air pollution (HAP) on placental growth markers. Two groups of pregnant women were identified: firewood/kerosene stove-users (A, n=33) and bioethanol stove-users (B, n=44) that participated in a randomized control trial in Ibadan, Nigeria. A third group of non-smoking and presumed liquefied petroleum gas-using Chicago women (C, n=19) were included in this exploratory pilot to assess for possible differences between similar racial groups. Levels of placental growth factor (PlGF) and soluble fms-like tyrosine kinase 1 (sFlt-1) were measured in maternal and cord plasma using ELISA. Maternal and cord blood sFlt-1 and PlGF did not differ significantly between women of groups A and B. Nevertheless, both groups differed significantly from the Chicago group in that group A women had lower maternal sFlt-1 (1372.50 vs. 3194.19) but higher PlGF (1607.87 vs. 442.80), and higher cord blood sFlt-1 (2925.02 vs. 107.53) and PlGF (223.68 vs. 6.92), all p≤0.001. Group B showed similar trends (all p≤0.002). Maternal PlGF levels were positively correlated to minutes of HAP exposure when PM2.5 concentration was above 100μg/m(3) in Nigerian women. Maternal levels of PlGF and cord blood levels of sFlt-1 and PlGF in Nigerian women with varying HAP exposures were significantly higher than Chicago-based women who had no presumed HAP exposure. It suggests that in-utero exposure to HAP influenced levels of angiogenic factors involved in normal placentation and growth and could represent compensation for pollutants exposure to preserve fetal viability.

    Objectives: To examine the construct and correlates of hopelessness among family caregivers of Nigerian psychiatric patients. Materials and Methods: This is a cross-sectional, descriptive study involving 264 family caregiver-patients’ dyads recruited from two university teaching hospitals psychiatric clinics in Southwestern Nigeria. Results: Exploratory factor analysis revealed a two-factor 9-item model of the Beck Hopelessness Scale (BHS) among the family caregivers. Confirmatory factor analysis of the model revealed satisfactory indices of fitness (goodness of fit index = 0.97, comparative fit index = 0.96, Chi-square/degree of freedom (CMIN/DF) = 1.60, root mean square error of approximation = 0.048, expected cross-validation index = 0.307, and standardized root mean residual = 0.005). Reliability of the scale was modestly satisfactory (Cronbach's alpha 0.72). Construct validity of scale was supported by significant correlations with the family caregivers’ scores on the Zarit Burden Interview, mini international neuropsychiatric interview suicidality module, General Health Questionnaire-12 (GHQ-12), and Patient Health Questionnaire-9. The greatest variance in the family caregivers’ scores on the BHS was contributed by their scores on the psychological distress scale (GHQ-12). Conclusions: The BHS has adequate psychometric properties among Nigerian psychiatric patients’ family caregivers. There is the need to pay attention to the psychological well-being of the family caregivers of Nigerian psychiatric patients.

  1. Genetic classification of petroleum systems

    Energy Technology Data Exchange (ETDEWEB)

    Demaison, G. (Stanford Univ., CA (United States)); Huizinga, B.J. (Chevron Overseas Petroleum Inc., San Ramon, CA (United States))

    1991-10-01

    The authors classification so petroleum systems is founded on a simple working nomenclature that consists of combining qualifiers from each of the following three categories: (1) charge factor, (2) migration drainage style, and (3) entrapment style. The charge factor is estimated on the basis of the richness and volumetrics of mature source rocks. The source potential index (SPI), which combines source-rock richness and thickness into a single parameter, is a convenient shortcut for comparing the petroleum potential of diverse source rocks containing dissimilar kerogen types and for rapidly estimating regional charging capacity. The migration drainage style is determined from the structural and stratigraphic framework of a basin. Vertical-migration drainage, which occurs mainly through faults and fracture systems breaching a seal, is characteristic of petroleum systems contained within rift basins, deltaic sequences, salt-dome provinces, wrench basins, and fold-and-thrust belts. In contrast, lateral-migration drainage sequences, salt-dome provinces, wrench basins, and fold-and-thrust belts. In contrast, lateral-migration drainage is dominant wherever stratigraphically continuous seal-reservoir doublets extend over a very large area in tectonically stable province. The entrapment style, which is also dependent on the structural framework and the presence and effectiveness of seals, describes the degree of resistance working against dispersion of the petroleum charge. Application of these working concepts should help to significantly reduce geologic risk, particularly in news ventures-type exploration.

  2. PETROLEUM BIOREFINING FOR POLLUTION PREVENTION

    2002-03-01

    The objective of this project was to isolate and characterize thermophilic bacterial cultures that can be used for the selective removal of nitrogen, sulfur, and/or metals in the biorefining of petroleum. The project was completed on schedule and no major difficulties were encountered. Significant progress was made on multiple topics relevant to the development of a petroleum biorefining process capable of operating at thermophilic temperatures. New cultures capable of selectively cleaving C-N or C-S bonds in molecules relevant to petroleum were obtained, and the genes encoding the enzymes for these unique biochemical reactions were cloned and sequenced. Genetic tools were developed that enable the use of Thermus thermophilus as a host to express any gene of interest, and information was obtained regarding the optimum conditions for the growth of T. thermophilus. The development of a practical biorefining process still requires further research and the future research needs identified in this project include the development of new enzymes and pathways for the selective cleavage of C-N or C-S bonds that have higher specific activities, increased substrate range, and are capable of functioning at thermophilic temperatures. Additionally, there is a need for process engineering research to determine the maximum yield of biomass and cloned gene products that can be obtained in fed-batch cultures using T. thermophilus, and to determine the best configuration for a process employing biocatalysts to treat petroleum.

    2008-01-01

    An experimental study of the rhizosphere effect on phytoremediation of petroleum polluted soil was carried out with three species of grasses,namely Pannicum,Eleusine indica (L.) Gaerth,and Tall Fescue.After a period of 150 days,this pot experiment showed that the rhizosphere of these three species accelerated the degradation of petroleum hydrocarbons to different extents.The results showed that the number of microorganisms in the rhizosphere increased by three orders of magnitude.The induction of the plant rhizosphere and the coercion influence of petroleum changed the species and activity of microorganisms.The degradation of petroleum hydrocarbons in the rhizosphere was 3-4 times that in unplanted soil.The dehydrogenase activity in the rhizosphere was 1.61-2.20 times that in unplanted soil,but the catalase activity was 0.90-0.93 times that in unplanted soil,and soil moisture content increased by 5% compared with the unplanted soil.

  4. Marine Tar Residues: a Review.

    Science.gov (United States)

    Warnock, April M; Hagen, Scott C; Passeri, Davina L

    Marine tar residues originate from natural and anthropogenic oil releases into the ocean environment and are formed after liquid petroleum is transformed by weathering, sedimentation, and other processes. Tar balls, tar mats, and tar patties are common examples of marine tar residues and can range in size from millimeters in diameter (tar balls) to several meters in length and width (tar mats). These residues can remain in the ocean environment indefinitely, decomposing or becoming buried in the sea floor. However, in many cases, they are transported ashore via currents and waves where they pose a concern to coastal recreation activities, the seafood industry and may have negative effects on wildlife. This review summarizes the current state of knowledge on marine tar residue formation, transport, degradation, and distribution. Methods of detection and removal of marine tar residues and their possible ecological effects are discussed, in addition to topics of marine tar research that warrant further investigation. Emphasis is placed on benthic tar residues, with a focus on the remnants of the Deepwater Horizon oil spill in particular, which are still affecting the northern Gulf of Mexico shores years after the leaking submarine well was capped.

    1991-01-01

    A case-controlled study was carried out on all the 51 juvenile delinquents found in a point prevalence survey of a Nigerian Borstal Remand Centre. Mean age of the delinquents was 17-27 years. They were mostly from the low social class (70.6%) and the commonest reason for admission was for being beyond parental control (68.6%). Identified risk factors found for juvenile delinquency were death of biological mother, parental marital failure, growing up with relatives rather than parents, drug abuse and ordinal position in the family. Possible cultural explanations for some of these observations were proffered. The need to improve on the living conditions of these juveniles and their assessment procedure were highlighted. Finally, it is imperative that the obsolete Nigerian Children and Young Person's Law be updated.

  9. Aspects of Connected Speech Processes in Nigerian English

    2014-12-01

    Full Text Available Nigerian English (NigE, like other new Englishes, possesses its unique features at various domains of phonology. This article examined aspects of connected speech processes (CSPs, the phenomena that account for sound modifications and simplifications in speech, with a view to establishing features that characterize Standard NigE connected speech. Natural phonology (NP, which provides explanations for substitutions, alternations, and variations in the speech of second language speakers, was adopted as theoretical framework. The subjects of the study were 360 educated NigE speakers, accidentally sampled from different language groups in Nigeria. The CSPs found in their semi-spontaneous speeches were transcribed perceptually and analyzed statistically, by allotting marks to instances of occurrence and converting such to percentages. Three categories of CSPs were identified in the data: dominant, minor, and idiosyncratic processes. The study affirms that only the dominant CSPs, typical of NigE speakers, are acceptable as Standard Nigerian spoken English.

    2003-01-01

    Six North Slope petroleum systems are identified, described, and mapped using oil-to-oil and oil-to-source rock correlations, pods of active source rock, and overburden rock packages. To map these systems, we assumed that: a) petroleum source rocks contain 3.2 wt. % organic carbon (TOC); b) immature oil-prone source rocks have hydrogen indices (HI) >300 (mg HC/gm TOC); c) the top and bottom of the petroleum (oil plus gas) window occur at vitrinite reflectance values of 0.6 and 1.0% Ro, respectively; and d) most hydrocarbons are expelled within the petroleum window. The six petroleum systems we have identified and mapped are: a) a southern system involving the Kuna-Lisburne source rock unit that was active during the Late Jurassic and Early Cretaceous; b) two western systems involving source rock in the Kingak-Blankenship, and GRZ-lower Torok source rock units that were active during the Albian; and c) three eastern systems involving the Shublik-Otuk, Hue Shale and Canning source rock units that were active during the Cenozoic. The GRZ-lower Torok in the west is correlative with the Hue Shale to the east. Four overburden rock packages controlled the time of expulsion and gross geometry of migration paths: a) a southern package of Early Cretaceous and older rocks structurally-thickened by early Brooks Range thrusting; b) a western package of Early Cretaceous rocks that filled the western part of the foreland basin; c) an eastern package of Late Cretaceous and Paleogene rocks that filled the eastern part of the foreland basin; and d) an offshore deltaic package of Neogene rocks deposited by the Colville, Canning, and Mackenzie rivers. This petroleum system poster is part of a series of Northern Alaska posters on modeling. The poster in this session by Saltus and Bird present gridded maps for the greater Northern Alaskan onshore and offshore that are used in the 3D modeling poster by Lampe and others. Posters on source rock units are by Keller and Bird as well as

    Chinwe Regina Pokoyeuzu

    2012-08-01

    Full Text Available The thrust of this paper is to see how changing gender identities and roles can impact and influence positive changes in Nigerian economy. There is every need to empower Nigerian women particularly in the present global economy which recognizes the need for individuals to develop their potentials and contribute to the overall development of the nation. The equity aspect implies that labour market participation of women will improve their relative economic position. It will also increase overall economic efficiency and improve development potentials of the country. Researchers world over observed that Should majority of the world’s population remain vulnerable to economic, political, legal and social marginalization, the hope of advancing democracy and prosperity will be jeopardized. This study analyzed the gender matrix in economic activities using secondary data obtained from CBN statistical Bulletin. The total percentage of women workers (participants engaged in one form of activity or the other in the economy is 43.1% as opposed to men’s 56.9%.This picture though appears nice statistically, is quite misleading. Key leading sectors in the economy by way of income yield or reward have not been favorable to women in terms of participation. Poverty will be reduced to the barest minimum if the government will take appropriate measures toimplement and enforce laws and policies directed towards enabling women have the same rights as Nigerian men.

  3. Digit preference in Nigerian censuses data of 1991 and 2006

    Directory of Open Access Journals (Sweden)

    Tukur Dahiru

    2013-06-01

    Full Text Available Background: censuses in developing countries are prone to errors of age misreporting due to ignorance, low literacy levels and other social, economic and cultural factors. Ages are commonly rounded with great affinity for 0 or 5. This tendency to digit preference and/or avoidance results in age heaping or concentration of ages at certain digits. This study examined the extent of digit preference in the Nigerian census data of 1991 and 2006.Methods: this study utilized age data from the 1991 and 2006 Nigerian censuses reported in single years. The Whipple and Myers indices were used to determine the extent of digit preference.Results: both the 1991 and 2006 census data showed the expected pattern of errors, with Whipple and Myers indices being beyond acceptable levels. The Whipple index for 1991 and 2006 was 293 and 251 respectively, while the Myers index was 62.3 and 67.1 respectively. There was a strong preference for terminal digits 0 and 5, followed by 8 whereas terminal digits 1 and 9 were strongly avoided.Conclusions: the quality of age data in Nigerian census data is poor as a result of misreporting and no significant improvement or difference was observed between 1991 and 2006 censuses.

    2015-01-01

    Full Text Available Background: The evaluation of degree of ventricular enlargement should be based on established indices rather than on personal experience as this is highly subjective. Our aim was to establish normal values for Evans index in a Nigerian adult population as none has been found in the Nigerian medical literature. Materials and Methods: Axial computerized tomographic brain scans of 488 normal subjects were reviewed retrospectively. Of them, 319 (65.36% of the patients were males and 169 (34.63% were females; their ages ranged from 18 to 84 years with a mean age of 37.26 years. The images were acquired using a multi-slice GE Sigma excite scanner. Evans index was measured as the linear ratio of the total width of the frontal horns of the cerebral lateral ventricles to the maximum intracranial diameter. Results: The mean value for Evans index for the studied population was 0.252 ± 0.04. The EI increased with age and it was slightly higher among males. The difference in Evans value in males and females was not statistically significant. Individuals above 60 years old had the highest Evans values in both sexes. Conclusion: This study has established ranges of normal value for Evans index in a Nigerian population. It agrees with the diagnostic cut-off value of > 0.3 for hydrocephalus and it compares well with that of the Caucasians.

    Male infertility constitutes a worldwide problem, especially in Nigeria where most men do not readily accept that they may contribute to the couple's infertility. In order to assess hormonal disturbances in the male infertility we compared male reproductive hormonal levels in human serum and seminal plasma and evaluated the hypothalamic-pituitary-testicular-axis in infertile Nigerian males. The biophysical semen parameters were assessed by W.H.O. standard manual method. Serum and seminal plasma male reproductive hormones (Leutinizing hormones, Follicular stimulating hormone, Prolactin and Testosterone) were measured by Enzyme Immunoassay (EIA) technique of W.H.O. in sixty (60) infertile adult male Nigerians (Oligospermic; n = 40 and azoopermic; n = 20) and forty controls of proven fertility (Normospermic subjects; n = 40). The results show that the serum concentrations of gonadotropins (LH and FSH) were significantly higher (Pinfertile subjects than controls. Patterns of serum prolactin levels were similar. The values of gonadotropins in serum were significantly higher (Pseminal plasma. Seminal plasma testosterone in infertile subjects was significantly higher (Phormonal level and seminal plasma hormonal level in all the groups (Pinfertility in Nigerians is characterized by hyperprolactinaemia, raised serum gonadotropins (LH, FSH), and raised seminal plasma testosterone. Hormonal profiles in serum and seminal plasma were not significantly correlated, and hence cannot be used as exclusive alternative in male infertility investigations. The observed spermogram in spite of significant elevation of seminal plasma testosterone in infertile males investigated suggests Sertoli cells malfunction.

    The Nigerian transplantation program is evolving but is currently over-reliant on living donors. If deceased donation is to be viable in Nigeria, it is important to ascertain the views of the public. The objective of the study was to explore the knowledge, attitudes, and behavior of Nigerian international students toward organ donation. A cross-sectional study was conducted among Nigerian international students of the University of Bedfordshire through the use of a modified self-administered questionnaire. The participants were recruited by means of purposive sampling. Of the 110 questionnaires distributed, 103 were returned fully completed (response rate = 93.6%). A significant majority (93.2%) of the participants are aware of organ donation, and 76.7% have a good knowledge on the subject. Furthermore, more than half (52.8%) of the participants have a positive attitude toward organ donation, and less than half (42.8%) have favorable behavior toward it. Higher knowledge does not correlate to either positive attitude or behavior, but a positive attitude is correlated with favorable behavior toward donation. The attitudes and behavior of the respondents toward organ donation is not commensurate with the level of knowledge they possess. This highlights the urgent need for well-structured educational programs on deceased organ donation. Copyright © 2017 Elsevier Inc. All rights reserved.

  7. Financial Intermediaries and Economic Growth: The Nigerian Evidence

    Oba Efayena

    2014-06-01

    Full Text Available This study seeks to examine the role of financial intermediaries and to find out whether financial intermediaries impact on economic growth in Nigeria. The study adopts the Harrod-Domar growth model which states that economic growth will proceed at the rate which society can mobilize domestic savings resources coupled with the productivity of the investment. The study employed the use of secondary data for the period 1981 to 2011 which were sourced from the CBN statistical bulletin. Nigerian banks being the dominant financial intermediaries, loans credits and advances from banks were used as proxy for the independent variable. Gross domestic product (GDP was used as proxy for economic growth. Using the technique of correlation analysis in determining the association between loan credits and advances, and the GDP, the study reveals a relatively high positive correlation between financial intermediaries and economic growth in the Nigerian economy. The study recommends that Nigerian banks should lend higher proportion of their loanable funds to small and medium enterprises (SMEs and should invest in information technology and human capital.

    Nigeria is a major producer of crude oil in sub-Saharan Africa. In-shore and off-shore wells are located in richly watered creeks in the southern part of the country. Although published data on environmental impact assessment of the petroleum industry in Nigeria are lacking, there is a growing concern about the possible contamination of estuarine and coastal waters and of marine species by polycyclic aromatic hydrocarbon (PAHs). PAHs are ubiquitous priority pollutants that occur naturally in crude oil, automobile exhaust emissions and smoke condensates from incomplete combustion of carbonaceous materials. PAHs with high molecular weight are less readily biodegraded by indigenous microorganisms in some regions, and given their marked hydrophobic characteristics, may persist in the aqueous environment, thus contaminating the food chain by bioaccumulating in aquatic species like fish and mussels. Major Nigerian oil wells are located in the vicinity of breeding and harvesting sites serving the fresh-water fishing industry. Large hauls of fresh fish are normally consumed cooked in soups or smoke cured in handcrafted traditional ovens using freshly cut red mangrove (Rhizophora racemosa) wood as fuel. Though smoke curing is economical and may ensure longer conservation of fish, it undoubtedly increases the burden of PAHs in finished products as a result of partial charring and from smoke condensates or mangroves that also contain PAHs in measurable quantities as reported by Asita et al. (1991). Apart from PAHs analyzed by Emerole (1980) in smoked food samples from Ibadan using simple analytical methods, those from industrial and other anthropogenic sources have rarely been analyzed in Nigeria. We tried therefore to update the data and address this discrepancy. 14 refs., 4 figs., 2 tabs.

  9. Norwegian Petroleum Policy; Norsk petroleumspolitikk

    This presentation discusses the environment, the petroleum fortune and future generations, licence policy, and regional issues. A principal aim for the Norwegian government is to combine the role as a major energy producer with the desire to be a leading country in environmental issues. Norway is now a major oil and gas producer that produces effectively, profitably and more environmentally friendly than other petroleum countries. The MILJOESOK process was started to strengthen the cooperation between Norwegian authorities and the industry in the environmental sector. The emissions of greenhouse gases per unit produced have been reduced. The emissions to sea of oil and chemicals are also being reduced. Another principle aim is that the oil and gas resources should give the highest possible value creation and secure welfare and employment. With the present production level the reserves of oil will last for 15 years and the reserves of gas for 110 years. The state income generated by the petroleum production is expected to peak around the turn of the millennium, then to decline gradually toward 2050. The petroleum fund is established to be a buffer till long into the future. In 2010, the yield from this fund is expected to be twice the amount of oil money used over the state budget today. Compared with the UK, Norway has chosen to exploit the resources in a step by step fashion at a moderate rate. This policy can be seen in the granting of concession. New concessions will be granted at a rate suitable for smoothing out the activity level and strengthening onshore employment. The North Sea, the Norwegian Sea and the Barents Sea are quite different as to mapping and maturity and hence require different concession policies. The new deep-sea fields in the Norwegian Sea offer technological challenges and it is important that offshore activities in this area create opportunities for regional development on land

    Petroleum products are complex substances comprising varying amounts of linear and branched alkanes, alkenes, cycloalkanes, and aromatics which may penetrate the skin at different rates. For proper interpretation of toxic hazard data, understanding their percutaneous absorption is of paramount importance. The extent and significance of dermal absorption of eight petroleum substances, representing different classes of hydrocarbons, was evaluated. Literature data on the steady-state flux and permeability coefficient of these substances were evaluated and compared to those predicted by mathematical models. Reported results spanned over 5-6 orders of magnitude and were largely dependent on experimental conditions in particular on the type of the vehicle used. In general, aromatic hydrocarbons showed higher dermal absorption than more lipophilic aliphatics with similar molecular weight. The results showed high variation and were largely influenced by experimental conditions emphasizing the need of performing the experiments under "in use" scenario. The predictive models overestimated experimental absorption. The overall conclusion is that, based on the observed percutaneous penetration data, dermal exposure to petroleum hydrocarbons, even of aromatics with highest dermal absorption is limited and highly unlikely to be associated with health risks under real use scenarios.

    Using 108 petroleum contaminated soil samples, this pilot study proposed a new analytical approach of combining visible near-infrared diffuse reflectance spectroscopy (VisNIR DRS) and portable X-ray fluorescence spectrometry (PXRF) for rapid and improved quantification of soil petroleum contamination. Results indicated that an advanced fused model where VisNIR DRS spectra-based penalized spline regression (PSR) was used to predict total petroleum hydrocarbon followed by PXRF elemental data-based random forest regression was used to model the PSR residuals, it outperformed (R{sup 2} = 0.78, residual prediction deviation (RPD) = 2.19) all other models tested, even producing better generalization than using VisNIR DRS alone (RPD's of 1.64, 1.86, and 1.96 for random forest, penalized spline regression, and partial least squares regression, respectively). Additionally, unsupervised principal component analysis using the PXRF + VisNIR DRS system qualitatively separated contaminated soils from control samples. Capsule: Fusion of PXRF elemental data and VisNIR derivative spectra produced an optimized model for total petroleum hydrocarbon quantification in soils. - Highlights: • PXRF elemental data and VisNIR DRS spectra were correlated to soil TPH. • VisNIR + PSR was used to predict TPH followed by PXRF + RF to predict the residuals. • The fused model produced better results than other multivariate models tested.

  7. HIV/AIDS communication in four Nigerian mainstream newspapers.

    One consensus in discussions on HIV/AIDS communication in low and middle income countries (LMICs) is the need for communication models to focus on activity rather than cognitive indicators in order to achieve desired improvements in health behaviors and outcomes. Past failures of HIV/AIDS communication efforts in LMICs have been attributed to emphasis on cognitive indicators. This study analyses HIV/AIDS communication models in Nigerian newspapers. Data were obtained through analysis of manifest content of four Nigerian papers issued between 2002 and 2004. Frequency, prominence and space dedicated to HIV/AIDS-related topics were measured. Descriptive statistics were used to highlight the frequency and percentage of cognitive- and activity-oriented information on HIV/AIDS. A total of 464 HIV/AIDS-related articles were identified. Fifty-nine percent (274) of articles were activity-oriented. Over half of articles were news stories. No news story made front and back pages lead. There were only nine editorials on HIV/AIDS. This study shows that the activity model of HIV/AIDS communication dominates the four Nigerian mainstream newspapers studied. However, it is worth noting the limited number of editorials and feature articles, which have the capacity to stimulate debate and foster a social environment in which AIDS is addressed in a spirit of openness. For a country that has the third largest number of people living with HIV/AIDS globally, one would expect the mass media to deliberately play an instrumental and a more active role in the battle against the disease by engaging in in-depth contextual discourse on HIV/AIDS.

    In Nigeria, just like in many other parts of the world, one of the most extensively discussed issues on the public agenda today is the increase in prison population. The aims of imprisonment are protection, retribution, deterrence, reformation and vindication. Investigations revealed that the prison services have been,neglected more than any other criminal justice agency in Nigeria. For example, most of the prisons were built during the colonial era for the purpose of accommodating a small number of inmates. Human Rights are the basic guarantees for human beings to be able to achieve happiness and self-respect; consequently, in most jurisdictions, the Human Rights Act confirms that these Rights do not stop at the prison gates. However, most States fail to meet the Human Rights obligations of their prisoners. As regards to health, for example, every prison should have proper health facilities and medical staff to provide dental and psychiatric care among others. This article discusses the Nigerian Prison System and challenges, trends and the related Human Rights and Ethical issues in Nigerian prisons. Some of the unmet needs of Nigerian prisoners which include, inter alia, living in unwholesome cells, delayed trial of inmates, lack of voting rights, access to information, lack of conjugal facilities for married prisoners, poor and inadequate nutrition, poor medical care, torture, inhumane treatment and the need to protect prisoners in a changing world. The present report has policy implications for reforming prison services in Nigeria, and countries that sing from the same song sheet with Nigeria on prison services, to conform to the Fundamental Human Rights of prisoners in the 21St century.

    Full Text Available There is no gainsaying that most of the recent forms of contemporary popular music produced, packaged, made available for public consumption constitute grave danger and serious threat to moral uprightness in Nigerian society. This has exposed the Nigerian society to a wide variety of insecurity and violence. This is evident as seen from series of moral decadence and dissipation that infiltrated the lives of the citizenry - especially the youths (the leaders of tomorrow ranging from, sexual abuse, money mongering, indiscipline, examination malpractice and indecent dressing to mention but a few. Music is a powerful tool and a force for mobilization which brings about either reformation or deformation of character due to the type of rhythm, melody, harmony and principally the lyrics of the songs. This paper examines the new trend of contemporary popular music in Nigeria with a view to assess its negative and pessimistic impacts on the character molding of the citizenry in Nigerian society. Live performances of contemporary popular music were observed and audio and video tape materials relating to the said music were also analyzed based on their educational  and moral values of such songs. It was  discovered that contemporary popular music as we have it today in Nigeria communicates vulgarity and coarseness to the listeners and this poses a lot of negative effects on the attitude of the youths. Musicians employ indecent words to attract the youth thus creating negative influence on the character of the leaders of tomorrow (the youth to engage in various   debauchery.  The paper therefore, suggested that relevant agencies should be put in place to ensure that apart from entertainment, music should convey positive character building messages rather than music that egg on and motivate illicit acts. Likewise, musicians should compose songs in the spirit of societal reformation so as to impact moral virtues on the younger generation  thus

    The aim of the study was to determine the acceptance and perception of Nigerian patients to medical photography. A self-administered questionnaire was distributed among Nigerian patients attending oral and maxillofacial surgery and plastic surgery clinics of 3 tertiary health institutions. Information requested included patients' opinion about consent process, capturing equipment, distribution and accessibility of medical photographs. The use of non-identifiable medical photographs was more acceptable than identifiable to respondents for all purposes (P = 0.003). Most respondents were favourably disposed to photographs being taken for inclusion in the case note, but opposed to identifiable photographs being used for other purposes most especially in medical websites and medical journals. Female respondents preferred non-identifiable medical photographs to identifiable ones (P = 0.001). Most respondents (78%) indicated that their consent be sought for each of the outline needs for medical photography. Half of the respondents indicated that identifiable photographs may have a negative effect on their persons; and the most commonly mentioned effects were social stigmatization, bad publicity and emotional/psychological effects. Most of the respondents preferred the use of hospital-owned camera to personal camera/personal camera-phone for their medical photographs. Most respondents (67.8%) indicated that they would like to be informed about the use of their photographs on every occasion, and 74% indicated that they would like to be informed of the specific journal in which their medical photographs are to be published. In conclusion, non-identifiable rather than identifiable medical photography is acceptable to most patients in the studied Nigerian environment. The use of personal camera/personal camera-phone should be discouraged as its acceptance by respondents is very low. Judicious use of medical photography is therefore advocated to avoid breach of principle of

Aim of the study To carry out a collaborative preliminary modern scientific evaluation of the efficacy of some Nigerian ethnomedicines used by traditional medicine practitioners (TMPs) in the management of tuberculosis and related ailments Materials and methods Ethnomedicinal recipes (ETMs) were collected from TMPs from locations in various ecological zones of Nigeria under a collaborative understanding. The aqueous methanolic extracts of the ETMs were screened against Mycobacterium bovis, BCG and Mycobacterium tuberculosis (M. tb.) strain H37Rv using the broth microdilution method. Results Extracts of ETMs screened against BCG showed 69% activity against the organism. The activities varied from weak, ≤ 2500μg /mL to highly active, 33μg /mL 64% of the extracts were active against M. tb. The activities of the extracts against M.tb. varied from weak, ≤ 2500μg /mL to highly active, 128μg/mL. There was 77% agreement in results obtained using BCG or M. tb. as test organisms Conclusion The results show clear evidence for the efficacy of the majority of indigenous Nigerian herbal recipes in the ethnomedicinal management of tuberculosis and related ailments. BCG may be effectively used, to a great extent, as the organism for screening for potential anti-M. tb. agents. A set of prioritization criteria for the selection of plants for initial further studies for the purpose of antituberculsis drug discovery research is proposed. PMID:24911338

    Full Text Available It is obvious that the use of newspapers is one of the ways through which literate farmers could access agriculture-related information and are acquainted with innovations in agriculture. This study investigated the content of agricultural training advertisements in three Nigerian newspapers: The Guardian, Nigerian Tribune and Daily Times. Using multistage sampling techniques, 240 editions of these newspapers containing 609 advertisements for five years (2001–2005 were selected. In terms of agricultural subsectoral coverage, 30.3% were on veterinary services while forestry services recorded the least advertisement (4.0 %. The Nigerian Tribune newspaper has the highest coverage of agricultural training advertisements 40.7% compared to the 34.7% and 12.2% for Daily Times and Guardian newspapers, respectively. The result also showed that majority of agricultural training advertisements (81.10% were placed on the non-prominent pages of the selected newspapers. Chi-Square analysis of association between the categories of agricultural training advertisements in the focal newspapers showed that there is significant relationship in the rate at which the sampled newspapers advertise different category of agricultural training advertisements in the newspapers (p<0.05. Chi square analysis also indicated that there is significant association between the placements of agricultural training advertisements and type of newspapers (p<0.05. This implies that advertisement placement on prominent pages of newspapers is determined by the policy of print media organization which also varies with cost of advertisement. It is therefore recommended that agricultural news items should be given more prominence as a panacea for increased information source to new entrants, especially the literate farmers to encourage farming.

    A modified Community Bureau of Reference (CBR) sequential extraction method was tested to assess the composition of untreated pyrogenic carbon (biochar) and oil sands petroleum coke. Wood biochar samples were found to contain lower concentrations of metals, but had higher fractions of easily mobilized alkaline earth and transition metals. Sewage sludge biochar was determined to be less recalcitrant and had higher total metal concentrations, with most of the metals found in the more resilient extraction fractions (oxidizable, residual). Petroleum coke was the most stable material, with a similar metal distribution pattern as the sewage sludge biochar. The applied sequential extraction method represents a suitable technique to recover metals from these materials, and is a valuable tool in understanding the metal retaining and leaching capability of various biochar types and carbonaceous petroleum coke samples.

    The Albertine Graben in western Uganda is a Mesozoic-Cenozoic riff basin with petroleum exploration potential. A fundamental evaluation of petroleum potential of the graben is given based on field research, data processing of gravity and magnetism, analysis of graben structure, geochemistry, reservoir and composition research. The basin has a double-layered framework and a large thickness of sediments. Gravity highs shown in a residual anomaly map might indicate central uplift zones. There exist at least two sets of mature or low-maturity source rocks corresponding to a certain source rock in the Cretaceous or Paleogene and Neogene strata. The graben has basement rock with potential reservoirs and Tertiary sandstone reservoirs and thus has petroleum exploration potential.

The requirement for optimal preventive maintenance, using, for instance, just-in-time (JIT) and total quality-management (TQM) techniques, has given rise to what has been called the total productive-maintenance (TPM) approach. This study explores the ways in which Nigerian manufacturing industries can implement TPM as a strategy and culture for improving its performance and suggests self-auditing and bench-marking as desirable prerequisites before TPM implementation.

    Eighteen cases of a congenital cystic swelling located over the anterior fontanelle are described in Nigerian patients who were otherwise clinically normal, There was a female: male ratio of 2: 1. Radiologically and at operation, the cysts showed no evidence of intracranial connexion. Excision was curative. Of 14 cases which were histologically verified, all were dermoid cysts except one in which nerve tissue was present suggesting an encephalocele. Air cystography was the most useful diagnostic procedure. ImagesFIG. 2FIG. 3FIG. 4 PMID:5555494

    Full Text Available The paper presents studies on oil removal from soil by means of water elution with a help of shaking out the contaminants from the soil. The tests were performed on simulated soil samples contaminated with a mixture of petroleum hydrocarbons. The study consisted in recording the time influence and the number of elution cycles to remove contaminants from the soil. The samples were then subject to the determination of petroleum hydrocarbons, aliphatic hydrocarbons, and BTEX compounds (benzene, toluene, ethylbenzene, xylene. Due to adding various concentrations of petroleum into particular soil samples and applying different shaking times, it was possible to find out the impact of petroleum content and sample shaking duration on the course and possibility of petroleum substances removal by means of elution process.

    A method for identification and concentration measurement of petroleum pollutant by combining three-dimensional (3-D) fluorescence spectra with parallel factor analysis (PARAFAC) was proposed. The main emphasis of research was the measurement of coexisting different kinds of petroleum. The CCl4 solutions of a 0# diesel sample, a 97# gasoline sample, and a kerosene sample were used as measurement objects. The condition of multiple petroleum coexistence was simulated by petroleum solutions with different mixed ratios. The character of PARAFAC in complex mixture coexisting system analysis was studied. The spectra of three kinds of solutions and the spectra of gasoline-diesel mixed samples, diesel-kerosene mixed samples, and gas oline-diesel mixed with small counts of kerosene interference samples were analyzed respectively. The core consistency diagnostic method and residual sum of squares method were applied to calculate the number of factors in PARAFAC. In gasoline-diesel experiment, gasoline or diesel can be identified and measured as a whole respectively by 2-factors parallel factors analysis. In diesel-kerosene experiment, 2-factors parallel factors analysis can only obtain the characters of diesel, and the 3rd factor is needed to separate the kerosene spectral character from the mixture spectrum. When small counts of kerosene exist in gasoline-diesel solution, gasoline and diesel still can be identified and measured as principal components by a 2-factors parallel factor analysis, and the effect of interference on qualitative analysis is not significant. The experiment verified that the PARAFAC method can obtain characteristic spectrum of each kind of petroleum, and the concentration of petroleum in solutions can be predicted simultaneously, with recoveries shown in the paper. The results showed the possibility of petroleum pollutant identification and concentration measurement based on the 3-D fluorescence spectra and PARAFAC.

    The environmental impact of using petroleum-contaminated sand (PCS) as a substitute in asphalt paving mixtures was examined. An appreciable component of PCS is oily sludge, which is found as the dregs in oil storage tanks and is also produced as a result of oil spills on clean sand. The current method for the disposal of oily sludge is land farming. However, this method has not been successful as an oil content of tests and environmental studies were conducted to establish the integrity of the materials containing the recycled sludge. These included physical and chemical characterization of the sludge itself, and an assessment of the mechanical properties of materials containing 0%, 5%, 22% and 50% oily sludge. The blended mixtures were subjected to special tests, such as Marshall testing and the determination of stability and flow properties. The experimental results indicated that mixtures containing up to 22% oily sludge could meet the necessary criteria for a specific asphalt concrete wearing course or bituminous base course. To maximize the assay from the recycled material, the environmental assessment was restricted to the 50% oily sludge mixture. Leachates associated with this particular mixture were assayed for total organic residue and certain hazardous metal contaminants. The results revealed that the organics were negligible, and the concentrations of the metals were not significant. Thus, no adverse environmental impact should be anticipated from the use of the recycled product. Our research showed that the disposal of oily sludge in asphalt paving mixtures could possibly yield considerable savings per tonne of asphalt concrete, and concurrently minimize any direct impact on the environment.

    Full Text Available The discovery of new coal deposits in Nigeria presents solutions for nation’s energy crises and prospects for socioeconomic growth and sustainable development. Furthermore, the quest for sustainable energy to limit global warming, climate change, and environmental degradation has necessitated the exploration of alternatives using cleaner technologies such as coal pyrolysis. However, a lack of comprehensive data on physico-chemical and thermal properties of Nigerian coals has greatly limited their utilization. Therefore, the physico-chemical properties, rank (classification, and thermal decomposition profiles of two Nigerian bituminous coals – Afuze (AFZ and Shankodi-Jangwa (SKJ – were examined in this study. The results indicate that the coals contain high proportions of C, H, N, S, O and a sufficiently high heating value (HHV for energy conversion. The coal classification revealed that the Afuze (AFZ coal possesses a higher rank, maturity, and coal properties compared to the Shankodi-Jangwa (SKJ coal. A thermal analysis demonstrated that coal pyrolysis in both cases occurred in three stages; drying (30-200 °C, devolatilization (200-600 °C, and char decomposition (600-1000 °C. The results also indicated that pyrolysis at 1000 °C is not sufficient for complete pyrolysis. In general, the thermochemical and pyrolytic fuel properties indicate that the coal from both places can potentially be utilized for future clean energy applications.

    Full Text Available There exist several religions in Nigeria. Many of them are exploited for political gains. As Samuel Huntington has predicted, given the collapse of communism, the main contention and controversy in the world would revolve around religion. The religious tension in present day Nigerian tends to fulfill the logic of the above stated position. This phenomenon has a long history in the country. Within the last couple of decades, Nigeria has witnessed a rise in the numbers of radical Islamic sects notably among them, Maitasine, Darul Islam, and Boko Haram. These sects have resorted to the use of violence in a bid to realizing their ambitions of a wider Islamization of the Nigerian Population. Three of the most prominent perspectives shared on the rise of these radical movements are: poor socio-economic infrastructures and poor governance, poverty as a major catalyst to the rapid increase in the membership of these groups and the increase and aiding of religious extremist by politicians for their selfish ambition. This study reveals that while it is true that socio-economic factors may drive the radicalization and politicization of religious sects in the country, the fear of domination and indeed the fight for supremacy is at the heart of the current insurgency in northeastern Nigeria.

    Colorectal cancer (CRC) is the fifth most common cancer in Africa, with significant differences in incidence, biology and clinical behavior from other populations. We studied prevalence and clinicopathological features of microsatellite instability (MSI) and young onset CRC in 83 archival samples from the University of Ibadan, Nigeria. Nigerian cases of CRC were MSI-high in 43% and MSI-high CRC had significantly lower histological heterogeneity than microsatellite-stable CRC (20% vs. 55% respectively, p=0.046). Presence of signet ring cell differentiation (10-50% of tumor) was significantly higher in younger patients with CRC (prevalence of mucinous (10%) and signet ring cell adenocarcinomas (4%) were among distinct features of Nigerian patients with CRC. MSI-high CRC is more common in West Africa and more detailed molecular and genetic analysis is warranted as CRC incidence and mortality continue to increase in the Sub-Saharan Africa.

    Full Text Available Corruption is a clog in the wheel of progress in Nigeria and has incessantly frustrated the realization of noble national goals, despite the enormous natural and human resources in Nigeria. The article reviews the concept of corruption in line with its forms and effects on the Nigerian State, as well as corruption in public service from Prime Minister Tafawa Balewa’s era to President Goodluck Jonathan’s administration. The article examines the idealistic, resource curse, two public, low risk–high benefit and anomie theories, and consequently adopts resource curse, low risk–high benefit theories to explain causes of corruption in Nigeria. Also, some personal observations and data from Transparency International are utilized to explain corrupt practices in Nigeria. The article concludes that there is corruption in the Nigerian Public Sector because of societal pressure, tribalism, nepotism, low risk–high benefits of involving in corruption among others. The article recommends some measures to combat corruption in Nigeria.

    Full Text Available ABSTRACT Background: Worldwide, obesity is increasing in prevalence, nearing epidemic proportions in the United States of America. Also, there are reports of rising prevalence in Africa. Obesity is an important aetiological factor for many non-communicable diseases. Recent anecdotal reports indicate that the prevalence of non-communicable diseases such as hypertension, type 2 diabetes mellitus and bronchial asthma is increasing among Nigerian military personnel; however, the rate of possible aetiological factors such as obesity is not known. Obesity can be evaluated using the body mass index (BMI, waist circumference and waist to height ratio (WHR. However, for epidemiological convenience and study within populations, the BMI is satisfactory. Methodology: A cross sectional study. Data of Nigerian military personnel�s annual medical examination conducted between January and March 2010 were retrieved to compute body mass index using World Health Organisation (WHO criteria. Results: 39.6% of personnel were overweight or obese. Most of these were aged between 30 and 39 years. While there were differences in the BMI of males and females, this did not reach statistical significance. Conclusion: To manage weight problems, focused health education, increased physical activity and nutritional advice are necessary. Modalities such as waist circumference should be added to annual medical examination of military personnel to improve the predictive value of the examination.

    Immunity to diphtheria has been noted to wane with age such that previous studies have shown that a significant proportion of females with characteristics comparable to those of Nigerian women of reproductive age have inadequate levels of immunity to diphtheria. Thus, it is envisaged that Nigerian newborns may inherit inadequate levels of immunity to diphtheria from their mothers. Cord blood and peripheral maternal blood samples were collected from 231 mother-infant pairs at delivery. Anti-diphtheria antibody titres were assayed using Enzyme-linked immunosorbent assay (ELISA) technique. Recruited babies were those born at term with normal birth weight. As much as 29.9% of both mothers and their babies had no protection (antibody titrediphtheria. Ninety (39.0% CI 33%,45%) mothers and 107 (46.3% CI 40%,52%) babies were inadequately protected (antibody titrediphtheria. The difference in the geometric mean antibody titres of mothers and babies was statistically significant (pdiphtheria. Vaccination of parturient women with booster doses of diphtheria toxoid vaccine is recommended. Copyright © 2014 Elsevier Ltd. All rights reserved.

    Full Text Available Abstract- Internet has consolidated into a cohesive entity and amalgamated itself as a very powerful platform that has changed the way people do things. Social Networking Sites (SNSs cannot be underestimated or jettison because no other communication medium which has given an international and globalized audience and dimension to the world like it. Facebook, Myspace, YouTube etc each of these and many other SNSs play a vital role on interaction and communication. The access to the internet for SNSs browsing is everywhere now. It is clearly established that even politicians, influential people, corporate managers, security agencies, lecturers, school administrators, and children are using SNSs thus students as well. Most SNSs are similar to each other there is commonality in their technical features. The study seeks to find out the level of students’ attitude towards SNSs usage in the selected northern Nigerian universities. Quantitatively it was found that Nigerian students have positive attitude towards the SNSs; and that there is no significant difference in terms of gender. However, differences were found significant in terms of faculties in the extent of students’ attitudes toward the SNSs usage.

  17. Due Process Mechanism and Fraudulent Practices in Nigerian Public Sector

    2015-09-01

    Full Text Available This study empirically examined whether due process mechanism serve as an antidote for fraudulent practices in the Nigerian public sector. Using 875 subjects in the public sector, the Pearson Product-Moment Correlation statistical tool was employed in order to establish whether due process mechanism is an antidote for fraudulent practices and also to see if due process ensures transparency in the public sector. The study found that due process ensures transparency and is an antidote for fraudulent practices. Another interesting finding from extant literature was that weak internal control system encourages fraudulent practices in the public sector. Thus, the need to re-embark upon moral, religious, ethical and social re-orientation in the public sector on the path of economic progress and development and not for political advantages is eminent as well as rigorous campaigns to awaken the conscious and re-orientate public servants and the general society on the need to refrain from fraud or abetting it. The internal control system operating in the public sector needs to be strengthened. Also, there is need for institutionalizing, internalizing and building ownership for the multitude of reforms within the public sector so as to ensure that it sustains the changes in the anti-corruption campaign in Nigeria. These trends need to continue for the dividends of due process to be fully realized in the Nigerian public sector.

  18. Entity, Ownership, Educational Subsidies and Funding of Nigerian Tertiary Institutions

    Idialu Jeremiah Uwaifo

    2012-02-01

    Full Text Available The motivation for this study is the need to save the Nigerian public tertiary institutions from going into extinction from under-funding. Funding of the institutions is currently on the basis of ownership. There is currently conflict of citizens’ right to education at whatever level at reduced cost or no cost at all and government’s inability to meet the cost of education. Government end up giving what it thinks it can afford and not what the institutions need to operate effectively. On the other hand the institutions are not given the free hand to determine what the beneficiaries of their services should pay. This study recommends that the institutions should be seen as separate entities from government and therefore be allowed to determine the price for their services. Citizens’ right should be met through educational subsidies from all levels of government. The balance fees should be picked by the beneficiaries of the services of the institutions. This is the surest way to the survival of tertiary institutions in the Nigerian environment.

    Trace elements are accepted to be involved directly or indirectly in the process of cancer formation. In this study, serum selenium, copper and zinc were measured in three groups of patients using atomic absorption spectrometer. A total of 29 Nigerian women were included: group I consisted of nine age-matched healthy controls without breast problems; group 2 included nine women with benign breast disease; and group 3 was comprised of women with breast cancer. The serum concentration of copper (Cu) was significantly higher in patients with cancer when compared to the control group (1.43 +/- 0.31 microg/ml vs 0.91 +/- 0.18 microg/ul/0.94 +/- 0.10 microg/ml). The zinc (Zn) concentration was significantly lower in the breast cancer group than in the other two groups (0.74 +/- 0.21 microg/ml vs 1.14 +/- 0.31 ug/ml/1.11 +/- 0.29 microg/ml; p copper and zinc in serum of patients with breast cancer, which may indicate abnormal copper and zinc metabolism in Nigerian females with breast cancer.

    Full Text Available Background: A carefully performed facial analysis can serve as a strong foundation for successful facial reconstructive and plastic surgeries, rhinoplasty or orthodontics. Aim: The purpose of this study is to determine the facial features and qualities of the Igbo Nigerian adult male using photometry. Materials and Methods: One hundred and twenty subjects aged between 18 and 28 years were studied at the Anambra State University, Uli, Nigeria. The frontal and right lateral view photographs of their faces were taken and traced out on tracing papers. On these, two vertical distances, nasion to subnasal and subnasale to menton, and four angles, nasofrontal (NF, nasofacial, nasomental (NM and mentocervical, were measured. Results: The result showed that the Igbo Nigerian adult male had a middle face that was shorter than the lower one (41.76% vs.58.24%, a moderate glabella (NF=133.97°, a projected nose (NM=38.68° and a less prominent chin (NM=125.87°. Conclusion: This study is very important in medical practice as it can be used to compare the pre- and post-operative results of plastic surgery and other related surgeries of the face.

  1. The Effects of Bank Distress on the Nigerian Economy

    Ademola Felix Adeyefa

    2015-09-01

    Full Text Available Bank distress poses threats to financial intermediation process with serious detrimental effect on the economy. Despite all attempts made by the supervisory authorities, the problem appears to defy already established approach and the menace still continues to resurface. Hence, the need to investigate the effects of bank distress on the Nigerian economy. The cointegration and error correction mechanism were used to test the data which covers a period of thirty-one  (31 years from 1982 to 2012. The research findings revealed that the ratio of non-performing loans to total loans, and total loans and advances have significant negative effect on economic growth with p-values of 0.0240 and 0.0445 respectively. Also, total bank deposit and cash reserve ratio have significant positive effect on economic growth with p-values of 0.0020 and 0.0374 respectively. The implication of this result is that the Nigerian economy is significantly affected by bank distress. The paper suggests that careful evaluation of loan proposals should always be carried out by banks to determine the viability of the projects and the repayment of the principal sum and its interest ensured to prevent weak asset quality.

  11. The General Unenforceability of Collective Agreements under Nigerian Labour Jurisprudence: The Paradox of Agreement without Agreement

    Directory of Open Access Journals (Sweden)

    Vincent Iwunze

    2013-12-01

    Full Text Available This study considers the status of collective agreements under Nigerian labour law, examining the extent of their enforceability under the extant laws. It considers the emerging trends in some more advanced jurisdictions of the world in that regard and comparatively portrays the anachronisms of the Nigerian law on the point. It takes the position that the current legal climate as regards the legal status of collective agreements under Nigerian law is potentially disruptive of industrial peace and harmony and is bound to occasion serious hardship on employees. The work suggests among others a jurisprudential shift in paradigm if the Nigerian labour jurisprudence must meet and be reflective of modern socio-economic realities.

    Hydrocarbon group type analysis is important in all conversion processes and in preparation of feed for these conversion processes so as to learn the selectivity of the different type of catalysts for product yield and quality. The use of the Mark 5 Iatroscan detector and the method reported here allowed for a rapid and quantitative hydrocarbon group type analysis of petroleum residues without prior separation of asphaltenes. SARA type analyses of petroleum residues have been performed by a three stage development using n-hexane, toluene and DCM (95%):MeOH (5%). The standard deviation and coefficient of variation in repeated measurements by this method were as low as 0.65 wt% or less and 3.5 wt% or less, respectively. The time required for analysis of 10 samples could be as short as 90 min. (orig.) With 2 figs., 6 tabs., 21 refs.

    Petroleum is used widely in health care—primarily as a transport fuel and feedstock for pharmaceuticals, plastics, and medical supplies—and few substitutes for it are available. This dependence theoretically makes health care vulnerable to petroleum supply shifts, but this vulnerability has not been empirically assessed. We quantify key aspects of petroleum use in health care and explore historical associations between petroleum supply shocks and health care prices. These analyses confirm that petroleum products are intrinsic to modern health care and that petroleum supply shifts can affect health care prices. In anticipation of future supply contractions lasting longer than previous shifts and potentially disrupting health care delivery, we propose an adaptive management approach and outline its application to the example of emergency medical services.

    In an experimental investigation of bioaugmentation products affected on the petroleum contaminated soil. The influence of the bioaugmentation products dose, injections and temperature on bioremediation were studied. The results showed that the degradation rate was related positively to the amount of inoculation, when the dose was increased to 0.6 mg x kg(-1), total petroleum hydrocarbon (TPH) degradation rate was 87% in 48 days. The results of GC-MS indicated that the dominant petroleum constituents in oil-contaminated raw soil were 82.1% n-alkane, 16% alkene and little of others hydrocarbons, such as carotane, alkylnaphthalenes, hopanes, and steranes. The peaks amount of GC profile decreased from 32 to 14 after 40 days of bioremediation, this result indicated that branched alkanes, alkene, and alkylnaphthalenes were thoroughly degraded, then line alkanes, hopanes, and steranes were left in soil. In addition, the longer part of n-alkane were degraded with rate relatively higher, while the residual fraction at the end of the test is shorter part of n-alkane because bacteria degraded the longer n-alkane to shorter. The shorter n-alkane concentration decreased with increasing inoculation. One time injection of bioaugmentation products into soil clearly improved the biodegradation efficiency higher than injection of bioaugmentation products in turn. Soil temperature also affected TPH degradation rate when it was 30 degrees C, TPH rate reached 80%, where as when it was 20 degrees C, the TPH rate was lower to 60%, which indicated higher temperature improved TPH degradation and accelerated bioremediation.

    Accumulation of heavy metals and histopathology were observed in Oreochromis niloticus exposed to treated petroleum refinery effluent from the Nigerian National Petroleum Corporation, Kaduna. Analysis of fish metal burden showed that the fish concentrated trace metals a thousand times above the levels existing in the exposure medium. Some metals were preferentially accumulated more than others and the accumulation was, in decreasing order, Pb, Fe, Zn, Cu, Mn, Cr, Ni, and Cd. Whole fish metal burden was lower in fish from which the gill, liver, and kidney had been removed, suggesting that these organs accumulated the metals more than other tissues. Hemorrhaging of fins was observed in all treatment concentrations except that of the control, and fish exposed to 40 and 50% effluent were most affected. Erosion of the caudal fin was also observed in fish exposed to 40 and 50% effluent. Examination of the organs for histopathology revealed damages to the gills. Gills with edematous fused lamellae congested with blood were observed. No histopathological damage was observed in the liver and kidney. The extent of metal accumulation and histopathological damage were directly related to the effluent concentrations.

    Todays, petroleum companies consider that despite the constant increase of petroleum consumption, petroleum will remain the main energy source for at least 40 years. However, after the Iraq conflict, new regional situations are changing. China, for instance, with its growing up demand, will change the physiognomy of the oil market. In parallel, from Indonesia to Africa, petroleum and religion interfere and explain the new conflict areas. As for the US strategy, which is not limited to the energy paradigm, it largely integrates energy in the main lines of its diplomacy, from the 'Wide Middle East' to the 'Sahel initiative', and in its position with respect to Venezuela.

    Full Text Available Through statistics published by the Shell Petroleum Development Company (SPDC, the paper explores why oilfield sabotage from 2009 to 2015 remains a problem in the Niger Delta, despite the 2009 amnesty programme. It explains why some of these incidents are a direct result of the failure to implement socio-economic development in successive state agencies due to corruption, a consequence of the natural resource curse. The article then explores why and how a Nigerian Non-Renewable Revenue Special Fund overseen by the United Nations Development Programme should be established which would not only manage a portion of oil revenue funds from the Niger Delta but also initiate valid social and economic projects in order to help reduce the prevalence of sabotage and instability in the region.

    How much of the total Norwegian emissions to air comes from the petroleum sector? What is the Norwegian petroleum industry's contribution to the discharges to sea? How do the Norwegian authorities manage the environmental aspects relating to the petroleum industry? What does nmVOC mean? In co-operation with the Norwegian Petroleum Directorate the Norwegian Ministry of Petroleum and Energy issues this publication to answer questions such as these. We furthermore wish to provide comprehensive information about the environmental aspects relating to the Norwegian oil and gas operations. It is also important to demonstrate that the efforts to improve environmental efficiency in this industry is a continuous process and that measures have already been implemented to this effect. Each year we take a closer look at one topic which is of concern to the petroleum industry. In light of the new protocol under the Convention of Long-range Transboundary Air Pollution, we wish to focus on the offshore sectors emission of NO{sub x} in this issue and on the possibilities and challenges we face in this context. This publication also contains a section containing factual data, which i.a. describes the status of discharges and emissions, environmental effects and measures to reduce the emission of CO{sub 2}, NO{sub x}, nmVOC and the discharge of oil and chemicals. We hope that a publication like this will increase the public's general knowledge of how the petroleum industry addresses environmental issues. An important task of the Ministry of Petroleum and Energy is to help formulate general guidelines and measures in areas where energy policy and environmental policy interact. It is furthermore our aim to help Norway combine her role as a major oil producer of energy with the role of being a leader in the protection of the environment.

    The Ministry of Petroleum and Energy produces an annual environmental review in cooperation with the Norwegian Petroleum Directorate. The purpose of this publication is threefold: (1) to increase knowledge about the environmental aspects of Norwegian oil and gas activities, (2) to take a more detailed look at a specific topic which particularly concerns both the industry and the authorities, and identify the challenges and options faced, (3) to emphasise the governments goal of ensuring that Norway reconciles its role as a large energy producer with a pioneering position on environmental issues. This year's edition focuses on the topic of ''oil and fish - common sea''. Both the petroleum and fishing industries depend on the waters off Norway. Ever since petroleum activities began on the Norwegian continental shelf more than 30 years ago, the authorities have been keen to ensure that these two sectors can work in the same sea areas. What challenges and opportunities face the petroleum industry over discharges to the sea and living marine resources? How can the authorities ensure that this sector is able to coexist with the fisheries? These and similar questions about the relationship between the petroleum and fishing industries in their shared seas are covered in section two of this publication. Environment 2002 also incorporates a factual section, which covers the status of emissions/discharges, environmental impacts and measures to reduce discharges to the sea and emissions to the air from petroleum activities. The MPE hopes that a publication of this kind can enhance basic knowledge about petroleum activities and environmental issues.
