    Full Text Available Abstract Background The Abuja target of increasing the proportion of people sleeping under insecticide-treated nets (ITNs to 60% by the year 2005, as one of the measures for malaria control in Africa, has generated an influx of resources for malaria control in several countries in the region. A national household survey conducted in 2005 by the Malaria Control Programme in Nigeria assessed the progress made with respect to ITN ownership and use among pregnant women and children under five years of age since 2000. The survey was the first nationally representative study of ITN use assessing progress towards the Abuja target amongst vulnerable groups. Population and Method A cross-sectional survey of a sample of 7,200 households, selected by a multistage stratified sampling technique from 12 randomly selected states from the six geopolitical zones of the country. Data collection was done during the malarious rainy season (October 2005 using a modified WHO Malaria Indicator Survey structured questionnaire about household ownership and utilization of mosquito nets (treated or untreated from household heads. Results Household ownership of any net was 23.9% (95% CI, 22.8%–25.1% and 10.1% for ITNs (95% CI, 9.2%–10.9%. Education, wealth index, presence of an under-five child in the household, family size, residence, and region by residence were predictive of ownership of any net. The presence of an under-five child in the household, family size, education, presence of health facility in the community, gender of household head, region by residence and wealth index by education predicted ITN ownership. Utilization of any net by children under-five was 11.5% (95% CI, 10.4%–12.6% and 1.7% (95% CI, 1.3%–2.2% for ITN. Predictors of use of any net among under-five children were fever in the previous two weeks, presence of health facility in the community, caregiver's education, residence, and wealth index by caregiver's education; while religion, presence of health facility and wealth index by caregiver's education predicted the use of ITN among this group. Conclusion This study demonstrated that the substantial increase in ITN utilization among children under five years of age in Nigeria is still far from the Abuja targets.

    Olusegun Ayodele, Akanbi.

    Full Text Available This study empirically examines the macroeconomic determinants of technological progress (total factor productivity) in Nigeria that is consistent with the endogenous growth theory. The estimations are carried out with time-series data from 1970 to 2006 using the Johansen estimation techniques. The [...] study is distinct from most of the existing literature since it made an attempt in generating a time-varying technological progress. It employs the Kalman filter technique to determine the evolution of the Solow residual estimated from a Cobb-Douglas production function. The results conform to the existing literature that macroeconomic instability, the level of financial development, and the level of human development are highly significant determinants of technological progress in Nigeria.

  4. Planning law versus the right of the poor to adequate housing: A progressive assessment of the Lagos State of Nigeria's Urban and Regional Planning and Development Law of 2010

    Scientific Electronic Library Online (English)

    Akinola E, Akintayo.

    Full Text Available The notion of the neutral application of law is the very foundation of liberal societies, in spite of the fact that this notion has been debunked as a myth by a large body of scholarship. This notion continues to pervade liberal societies, operates discriminately against the poor and less privileged [...] members of society and impedes poverty reduction efforts. The article demonstrates the exclusionary and discriminatory operation and impact of the myth of the neutral application of law on the right of the poor to adequate housing through a progressive assessment of the Lagos State of Nigeria's Urban and Regional Planning and Development Law, 2010, a supposedly neutral planning statute. It concludes that, for the fight against poverty to make any headway in Africa, poverty reduction must continually be mainstreamed. There must constantly be a pro-poor approach to laws and policies.

    2012-05-01

    Full Text Available Music embodies culture, expressing relevant features of a people’s life. Music is an integral aspect of African culture, occupying a special place in the celebration of birth and death and other events in-between. Indeed it is difficult to imagine life without music in traditional Nigerian society where all strata and age groups have their own music; a richness of life that urban communities failed to totally replicate, being that they are composites of ethno-linguistic fragments. Thus, the evolving youth popular music culture is significant in many respects, especially as it cuts across ethnic divides and provides entertainment for a group in heretofore largely ignored in Nigerian urban society. Its potentials, and its retrogressive potency, in national development require that popular culture be studied to ascertain the message and mindset of active and passive participants. This article summarises aspects of youth music in Nigeria as assessed by undergraduate students.

    Background: Use of ionising radiation in diagnostic radiography could lead to hazards such as somatic and genetic damages. Compliance to safe work and radiation protection practices could mitigate such risks. The aim of the study was to assess the knowledge and radiation protection practices among radiographers in Lagos, Nigeria. Materials and Methods: The study was a prospective cross sectional survey. Convenience sampling technique was used to select four x-ray diagnostic centres in four tertiary hospitals in Lagos metropolis. Data were analysed with Epi- info software, version 3.5.1. Results: Average score on assessment of knowledge was 73%. Most modern radiation protection instruments were lacking in all the centres studied. Application of shielding devices such as gonad shield for protection was neglected mostly in government hospitals. Most x-ray machines were quite old and evidence of quality assurance tests performed on such machines were lacking. Conclusion: Radiographers within Lagos metropolis showed an excellent knowledge of radiation protection within the study period. Adherence to radiation protection practices among radiographers in Lagos metropolis during the period studied was, however, poor. Radiographers in Lagos, Nigeria should embrace current trends in radiation protection and make more concerted efforts to apply their knowledge in protecting themselves and patients from harmful effects of ionising radiation.

    Full Text Available Poverty situation in Nigeria has become so serious that in 2013 there were as many as 112 million or 70.0% of the country’s population was living below poverty line. It has realized that poverty anywhere is a threat to peace, security and prosperity everywhere hence the conscious efforts by successive administrations in Nigeria to eradicate all forms of extreme poverty and hunger in a country. In spite of these efforts to eradicate absolute poverty in the country, poverty incidence has been on the rise. This study, therefore, attempted to assess NAPEP as a programme to eradicate extreme poverty in the country. Personal interviews and documents were employed in data collection. The data were analyzed using tables, simple percentages and spearman rank correlation. The study showed among others, that NAPEP as a programme targeted at eradicating extreme poverty has not been effective leading to a mixed bag of limited success and continuing challenges. It was therefore, recommended that the programme should be re-examined and possibly re-designed for effective performance instead of scrapping it.

    Nigeria's 1980 population size is 77,082,000 with a midestimate of 149,965,000 by the year 2000. Population growth is estimated at 3% and the government believes that this rate is satisfactory given a longrun perspective even though problems such as pressure on resources and unemployment do exist. Life expectancy is 47.5 years and morbidity and mortality trends are considered unacceptable; there is a policy to reduce mortality through primary health care. The crude birth rate is 49.8% which is deemed satisfactory while admitting such problems as low levels of maternal and child health, short birth intervals, and malnutrition. Integration of family planning within a maternal health policy is the current practice while abortion is restricted and contraceptives are available only through the government. 20.4% of the population live in urban areas and the rate of urban growth is 5.5%. Policies exist to encourage rural-urban migration and to slow down the growth of Greater Lagos by developing a new national capital. The government of Nigeria approaches population as a quality of life matter; policies emphasize lowering morbidity and mortality and keeping urbanization within manageable proportions. Censuses have been conducted since 1866 although the 1st modern census was in 1952/53, and the latest is the 1962 census. The National Population Commission which implements population policy and coordinates external support for family planning is located within the Central Planning Office. The government plans to establish a federal population unit attached to the Central Planning Office, as well as to develop state units. PMID:12311800

    1994-11-01

    Detailed study of chemical analysis results of several groundwater samples (UNICEF-Assisted Water project, Kwara state, Nigeria) were carried out in an attempt to assess the quality and usability of groundwaters in the Moro area. Chemical analysis results indicate higher concentrations of Ca2+, Mg2+, and HCO3 - as compared to Na+, K+, Cl-, and SO4 2-. With exception of few locations where Fe is relatively higher, the concentrations of these ions together with other water quality parameters are all within permissible limits of the domestic and agricultural standards. On the basis of the analytical results, groundwaters in the study area are largely characterized as Ca-(Mg)-HCO3 type reflecting (possibly) young facies with limited migratory history. The occurrence of Ca-(Mg)-Na-HCO3 water type in certain areas is attributed to cation exchange processes. In addition, the observed scattered relationship between the TDS and the thickness of weathered horizons in the boreholes indicates the contribution of precipitation (recharge) to the ionic inputs in the groundwaters in addition to the weathering and dissolution processes.

  14. Contamination of Sachet Water in Nigeria: Assessment and Health Impact

    Full Text Available Adequate supply of fresh and clean drinking water is a basic need for all human beings. Water consumers are frequently unaware of the potential health risks associated with exposure to water borne contaminants which have often led to diseases like diarrhoea, cholera, dysentery, typhoid fever, legionnaire’s disease and parasitic diseases. The inadequacy of pipe borne water-supply in Nigeria is a growing problem; as a result people resort to buying water from vendors, and sachet or bottled water became a major source of drinking water. Although, portable and affordable, the problems of its purity and other health concerns have begun to manifest. Sachet water have been reported to contain bacteria such as Bacillus sp., Pseudomonas sp., Klebsiella sp., Streptococcus sp., and oocysts of Cryptosporidia sp. Apart from environmental contaminants, improper storage and handling by vendors also poses a serious threat to the health of the ignorant consumers. This paper tends to review the quality of these ‘pure water’; its physical examination, microbial assessments, its impacts on health, and the various strategies adopted by the concerned authorities to regulate this thriving industry.

    Full Text Available The study was carried out to assess the levels of concentration and distribution of Pb, Cr, Fe, Cd, Co, Ni, Zn and Cu in Galma dam, Zaria, Nigeria which spanned to 35Km. The main source of data was the surface water from the lower and the upper regions of the dam. The samples were collected and prepared in the laboratory according to standard method, Atomic Absorption Spectrophotometry (AAS technique was used to analyze the data. The results showed concentration of Pb, Cr, Fe, Cd, Co, Zn and Cu at various levels and the concentration of Ni below detectable level. The results also showed the distribution of these elements at lower and upper regions of Galma dam. The enrichment of these heavy elements in the dam could be explained by the loading of the dam with debris and effluents produced by various human activities within the dam catchment area through overland and base flows and the release of elements from geologic processes. The concentration of Pb, Cr and Fe were observed to be slightly above NIS and WHO standards for drinking water. To minimize pollution of the reserviour, it is strongly recommended that there should be reduction in levels of some unhealthy practices such as indiscriminate discharge of effluents like, engine oil, lubricants, used batteries, electric bulbs/fluorescent tubes, electronic and electrical appliances and high level use of chemicals on the farms are recommended to be discouraged.

    2013-01-01

    Full Text Available This study sought to investigate the assessment of client and contractor organizations on the use of the design-bid-build method for project delivery in Nigeria. One hundred fifty seven questionnaires were administered purposively on contracting and client organizations in Nigeria. Sixty seven organisations responded to the questionnaire. The responses were analysed through the use of descriptive and inferential statistical tools. Of the twenty issues used for the assessment, ‘individual participants are exploitative of loopholes in contract documents’ ranked first on aggregation for the two groups. ‘Relationships among participants breed mistrust’ ranked least. On the average, contractors and clients disagree with the twenty issues or criticisms about the traditional procurement practice. The results of the analysis further indicate that there are no significant differences in perceptions on the issues between the two groups. It is recommended that the homogeneity of perceptions can be a launching pad for further investigation and intervention efforts for procurement improvement in Nigeria.

    International Nuclear Information System (INIS)

    On June 27, 1989, the Secretary of Energy announced a 10-Point Initiative to strengthen environment, safety, and health (ES ampersand H) programs, and waste management activities at DOE production, research, and testing facilities. One of the points involved conducting dent Tiger Team Assessments of DOE operating facilities. The Office of Special independent Projects (OSP), EH-5, in the Office of the Assistant Secretary for Environment, Safety and Health, EH-1, was assigned the responsibility to conduct the Tiger Team Assessments. Through June 1992, a total of 35 Tiger Team Assessments were completed. The Secretary directed that Corrective Action Plans be developed and implemented to address the concerns identified by the Tiger Teams. In March 1991, the Secretary approved a plan for assessments that are ''more focused, concentrating on ES ampersand H management, ES ampersand H corrective actions, self-assessment programs, and root-cause related issues.'' In July 1991, the Secretary approved the initiation of ES ampersand H Progress Assessments, as a followup to the Tiger Team Assessments, and in the continuing effort to institutionalize the self-assessment process and line management accountability in the ES ampersand H areas. This manual documents the processes to be used to perform the ES ampersand H Progress Assessments. It was developed based upon the lessons learned from Tiger Team Assessments, the two pilot Progress Assessments, and Progress Assessments that have been completed. The manual will be updated periodically to reflect lessons learned or changes in policy

    Toxicological evaluation of Clarias gariepinus from bitumen-polluted River Oluwa, Nigeria, was carried out in furtherance of studies on the environmental impacts of the bitumen exploration in Ondo State, Nigeria. Samples were taken from three different (two polluted and one as control) sites. The effect of changes in monthly seasonal flow rate was assessed for the sites of study. Blood plasma clinical-chemical parameters (BCCPs) and histological changes/lesions in various organs were evaluated as markers of pollution in the fish blood using standard methods. The result of the physicochemical properties of water from the sampling points revealed some of the values conforming to approved standards while others showed deviation. Significant differences were found in the blood and histological endpoints between the control and the polluted sites as well as between the two seasons evaluated across the sites. The public health implications of consuming this fish are fully discussed. PMID:26725477

    This article assessed the relevance of Adekanye’s book titled “The Retired Military as Emergent Power Factor in Nigeria” to contemporary Nigeria. The eight chaptered book examined the growing power and influence of top retired military offi cers in Nigeria in every sector of the economy due to their wealth, ex-military connection, skill, prestige and experience. It posits that the military retirees are grouped into two contradictory categories, the growing rate of military retiree has been on the increase since 1966, the retired military are found virtually in every aspect of human endeavour and compete with those in the social group in political scene, and are fast emerging as new elite of power, with considerable infl uence in decision making that deals with issues of high politics. All these assumptions were correct except that few top military retirees have since 1999 emerged as the ruling elite and even though they are not physically in power now have to a great extent determined who occupied the site of power. The Peoples’ Democratic Party which is the leading political party have been greatly infl uenced by these rich and influential retired military officers who at all cost ensure that their candidates win the elections. With the appointment of a new INEC chairman, the review of the electoral act, and the campaign for free and fair election, it is believed that a new set of elite will emerge that will awaken political development in Nigeria.

  9. Assessment of Noise and Associated Health Impacts at Selected Secondary Schools in Ibadan, Nigeria

    International Nuclear Information System (INIS)

    Background. Most schools in Ibadan, Nigeria, are located near major roads (mobile line sources). We conducted an initial assessment of noise levels and adverse noise-related health and learning effects. Methods. For this descriptive, cross-sectional study, four schools were selected randomly from eight participating in overall project. We administered 200 questionnaires, 50 per school, assessing health and learning-related outcomes. Noise levels (A-weighted decibels, dBA) were measured with calibrated sound level meters. Traffic density was assessed for school with the highest measured dBA. Observational checklists assessed noise control parameters and building physical attributes. Results. Short-term, cross-sectional school-day noise levels ranged 68.3-84.7 dBA. Over 60% of respondents reported that vehicular traffic was major source of noise, and over 70% complained being disturbed by noise. Three schools reported tiredness, and one school lack of concentration, as the most prevalent noise-related health problems. Conclusion. Secondary school occupants in Ibadan, Nigeria were potentially affected by exposure to noise from mobile line sources.

    Full Text Available Twenty water samples were obtained in Akungba Akoko, Ondo State, Nigeria in order to determine the groundwater quality in the area. Thirteen samples were obtained from hand-dug wells, two samples were obtained from a spring while the remaining five samples were collected from boreholes. These samples were subjected to both physical and chemical analyses with a view to comparing the results obtained with the World Health Organization’s (WHO standard for quality drinking water. The results of the physical parameters measured shows that the colour ranges from 5°H to 50°H, turbidity ranges from 2NTU to 40NTU and the electrical conductivity ranges from 2.2×102 mho/cm to 1.4×103 mho/cm. Chemical analysis results on the other hand show that all the samples have pH within the weakly acidic range except for sample HDW 3 that falls within the weakly alkaline range. Furthermore, the Total Dissolved Solids (TDS range from 154 to 980 mg/L while the Total Hardness of the water samples range from 24 to 280 mg/L. Ionic studies show that the Ca2+, Na+, K+ and Mg2+ occur in order of decreasing abundance in the samples with the concentrations ranging from 10 to 160 mg/L, 20 to 90 mg/L, 10 to 90 mg/L and 14 to 150 mg/L, respectively. The anions present in the water samples in order of decreasing abundance are HCO3-, Cl-, SO2-4 and NO-3 with their concentrations ranging from 44 to 292 mg/L, 10 to 77 mg/L, 0.01 to 50 mg/L and 0.01 to 4.0 mg/L, respectively. It has been shown that anthropogenic inputs can continually ruin the suitability of the water for safe drinking purpose. Therefore, the ability to quickly control the anthropogenic inputs to the groundwater system in Akungba Akoko area will assist in keeping the quality of groundwater in Akungba Akoko to be maintained.

    On June 27, 1989, the Secretary of Energy announced a 1O-Point Initiative to strengthen environment,safety, and health (ES ampersand H) programs, and waste management activities at involved conducting DOE production, research, and testing facilities. One of the points independent Tiger Team Assessments of DOE operating facilities. The Office of Special Projects (OSP), EH-5, in the Office of the Assistant Secretary for Environment, Safety and Health, EH-1, was assigned the responsibility to conduct the Tiger Team Assessments. Through June 1992, a total of 35 Tiger Team Assessments were completed. The Secretary directed that Corrective Action Plans be developed and implemented to address the concerns identified by the Tiger Teams. In March 1991, the Secretary approved a plan for assessments that are ''more focused, concentrating on ES ampersand H management, ES ampersand H corrective actions, self-assessment programs, and root-cause related issues.'' In July 1991, the Secretary approved the initiation of ES ampersand H Progress Assessments, as a followup to the Tiger Team Assessments, and in the continuing effort to institutionalize the self-assessment process and line management accountability in the ES ampersand H areas.

    Full Text Available Few studies have systematically characterized drug-prescribing patterns, particularly at the primary care level in Nigeria, a country disproportionately burdened with disease. The aim of this study was to assess the disease profiles and drug-prescribing pattern in two health care facilities in Edo State, Nigeria. The medical records of 495 patients who attended a primary or secondary health care facility in Owan-East Local Government Area of Edo State, Nigeria, between June and November 2009 were reviewed. Disease profiles and drug prescribing patterns were assessed. Data were analyzed based on the World Health Organization Anatomic Therapeutic Chemical classification system, and core drug prescribing indicators. Five hundred and twelve clinical conditions were identified. Infectious disease was most prevalent (38.3%, followed by disorder of the alimentary tract (16.4%. Malaria was responsible for 55.6% of the infectious diseases seen, and 21.3% (109/512 of the total clinical conditions managed at the two health facilities during the study period. Consequently, anti-infective medications were the most frequently prescribed medicines (21.5%, followed by vitamins (18.2%. Use of artesunate monotherapy at both facilities (15.7%, and chloroquine at the primary health facility (24.9% were common. Paracetamol (41.8% and non-steroidal anti-inflammatory drugs (24.9% were the most frequently used analgesic/antipyretic. At the primary health care facility, dipyrone was used in 21.6% of cases. The core drug prescribing use indicators showed inappropriate prescribing, indicating poly-pharmacy, overuse of antibiotics and injectio. Inappropriate drug use patterns were identified at both health care facilities, especially with regard to the use of ineffective antimalarial drugs and the use of dipyrone.

  16. Can the Nigerian biofuel policy and incentives (2007) transform Nigeria into a biofuel economy?

    International Nuclear Information System (INIS)

    Nigeria's economy is largely dependent on petroleum, yet the country is suffering from fuel supply shortages. In response to the transportation fuel supply difficulties in Nigeria, the country released the Nigerian Biofuel Policy and Incentives in 2007 to create favorable investment climate for the entrance of Nigeria into the biofuel sector. The paper assessed the progress made thus far by Nigeria, 4 years after the Nigerian biofuel was released in an attempt to answer the question whether the policy is adequate to transform Nigeria into a biofuel economy. The study found that little progress has been made, which includes commencement of the construction of 20 bioethanol factories, installation of biofuel handling facilities at two depots (Mosimi and Atlas Cove), and selection of retail outlets for biofuel/conventional fuel mix. The site construction of the announced biofuel projects is now slow and other progress is marginal. We therefore conclude that the Nigerian biofuel policy is unlikely to transform Nigeria into a biofuel economy unless the Government revert and refocus on biofuel and include additional financial incentives such as grants and subsidy to complement the tax waivers (income, import duty, VAT), loans, and insurance cover contained in the policy. - Highlights: ? Nigeria's economy is dependent on petroleum, yet the country is suffering from fuel shortages. ? The Nigerian Biofuel Policy and Incentives was released in 2007. ? Little progress has been made since the policy was released 4 years ago. ? Hence, the policy is unlikely to transform Nigeria into a biofuel economy

  17. Naturally occurring radioactive material (NORM) assessment of oil and gas production installations in Nigeria

    International Nuclear Information System (INIS)

    Naturally occurring radioactive material (NORM) assessment was carried out at oil production platforms and gas processing units in Nigeria with the aim of establishing baseline levels and problem areas. The assessment consisted of external radiation measurements on production units, from the wellheads to the product outlets, sampling and gamma spectrometric analysis of scales and sludge from pig stations and of replaced pipes and vessels. The NORM levels on the installations and associated equipment ranged from 0.1 to 15 ?Sv/h and gamma spectrometric analysis indicates the presence of 226Ra, 214Bi and 214Pb in the scales and sludge, having a maximum concentration of 200 Bq/g. The levels may seem low but there is still the need to establish a routine monitoring programme for the industry, which presently is non-existent. (author)

    Full Text Available Achieving food security is still a major problem for households in most rural areas of Nigeria. This study was therefore designed to assess the food security status among farming households in rural areas of Kano state, Nigeria. The study utilized a multistage random sampling technique to +select a sample of 120 rural farm households for interview. Data collected were analysed using percentages, mean score, logistic regression and food security index. Using the food security index approach, the study revealed that 74% of the respondents were food secure while 26% were food insecure. The results of the logistic regression revealed that educational level (p0.05; z = 1.95, sex (p0.05; z = 1.99, household size (p0.05; -4.29 and access to credit (p0.05; z = 2.4 were significant determinants of food security. Also, the major effect of food insecurity on the households include reduction in household income/ savings due to increased expenditure on food (M= 3.58, among others. The perceived coping strategies in cushioning the effects of food insecurity include engaging in off-farm and non-farm jobs to increase household income, (M= 2.77, among others. The study therefore recommends the fast tracking of already established policy measures aimed at reducing food insecurity in the country. Also, efforts aimed at reducing food insecurity among rural farming households should focus on increasing household income and food supply.

    1996-01-01

    Full Text Available The "Structural Adjustment Programme" (SAP was introduced in 1986 to restructure and diversify the productive base of Nigerian economy, increase domestic food production, agricultural raw materials and enhance non-oil exports. Poultry farmers under SAP have witnessed a downward trend in their production and have therefore stated that SAP is an illwind that blows nobody any good since it has increased their problem rather than solve them. This study was therefore carried out to assess the effects of SAP on poultry production in Nigeria between 1985 - 1990. It was observed that the Structural Adjustment Programme has had tremendous effects on poultry industry in Nigeria. The farmers have not adjusted favourably to the effect of SAP with 75 % of them operating between 20 - 50 % and 19 % below 20 % of production capacity. Currently the industry is being operated below 30 % mainly due to the high cost of chicks and inputs some of which have risen to over 1000 %. Productivity of the birds has also been affected with about 30 % reduction in the number of eggs laid per bird per year. Age at maturity has also increased to about 30 % among broilers. Farmers found it difficult to buy feed and drug resulting in increased mortality of about 80 % among broilers. The rise in the prices of product of about 500 % does not match the increase cost of production. Recommendations are therefore made to help stabilise the poultry industry.

    Full Text Available This study focuses on an impact assessment of the consolidation exercise on the performance of commercial banks in Nigeria. While prior studies focused on the financial performance of banks (with emphasis on profitability, the main thrust of this study was on how the consolidation exercise had affected different areas of commercial banks in Nigeria other than profitability. Secondary data were sourced from the annual accounts and statistical bulletins of the CBN and SEC respectively for the relevant years. The data obtained were analysed by means of sensitivity analysis, in addition to the correlation and regression analyses. The results obtained show that the consolidation exercise had positive impact on the selected variables (Non Performing Loans, Liquidity Ratio, Bank Credit to Private Sector and Bank Capital To Asset Ratio for this study. Based on the above findings, we recommend among others that while efforts are made by the CBN to sustain the increased capital base of banks, a very sound corporate governance framework and effective risk management systems must be put in place to check the level of non-performing loans which seem to be predominant in the industry. The quality of bank credit to private sector and their recovery procedures should also be improved upon.

    Full Text Available To provide a universal basic education, Saudi Arabia initially employed a rapid quantitative educational strategy, later developing a qualitative focus to improve standards of education delivery and quality of student outcomes. Despite generous resources provided for education, however, there is no national assessment system to provide statistical evidence on students’ learning outcomes. Educators are querying the curricula and quality of delivery for Saudi education, especially following low student performances on the Trends in International Mathematics and Science Study (TIMSS in 2003 and 2007. There is a growing demand for national assessment standards for all key subject areas to monitor students’ learning progress. This study acknowledges extant research on this important topic and offers a strategy of national assessment to guide educational reform.

    The geophysical-based integrated electrical conductivity (IEC) and the groundwater hydraulic confinement-overlying strata-depth to water table (GOD) techniques were used to assess vulnerability levels of aquifers and the extent of aquifer protection in Abi, Nigeria. The IEC indices was generated from constrained one dimensional (1D) inversion of vertical electrical sounding (VES) and two dimensional (2D) electrical resistivity tomography (ERT) data, acquired randomly in the area. The GOD indices were sourced from existing geologic data within the area. Results showed that IEC values vary from protected areas to >2.0 S in the strongly protected areas. The GOD indices vary from areas to 0.6 in the highly vulnerable areas. Thus, the groundwater resources in the area need to be properly managed for sustainability and such management practices have been suggested. PMID:25736831

    2008-01-01

    Full Text Available The aim of this research was to assess the impact of abattoir effluents on River Illo in Ota, Nigeria. In order to achieve this set objective seven sampling locations were chosen along the river course. The choice of locations was to reflect the variations in concentrations of the following important parameters of water quality issue: pH, conductivity, total dissolved solids, total suspended solids, dissolved oxygen, biochemical oxygen demand, chemical oxygen demand, ammonia and nitrate among others. The choice of these parameters was based on their relative importance in abattoir effluents composition. Results of analyses revealed impairment in the quality of River Illo by the wash down from the abattoir activities. Dissolved oxygen concentrations ranged between 0.01 and 4.6 mg L-1 while the highest concentrations of TSS and TS of 1026 and 1071.5 mg L-1, respectively were obtained at the point of abattoir effluents discharge. The BOD mean value of 312.9 mg L-1 obtained for the river water is far above the highest permissible value of 30 mg L-1 allowed by the Federal Environmental Protection Agency for discharge into receiving water bodies in Nigeria. The mean value of 783 mg L-1 obtained for the COD of the river body corroborates the pollution of the water body. The current water quality status of River Illo from the discharge of abattoir effluents therefore poses both environmental and health hazards to users. In order to redress this and ensure public health safety, River Illo needs adequate treatment before use.

    Studies on psychoactive substance use in Nigeria had focused on prevalence and rarely on treatment implication(s) of large rates reported. Further challenge was to find suitable instruments to monitor change readiness as well as predict treatment outcomes along motivation continuum and according to resilience characteristics. Such ability will not only help to match treatment strategy with stage of change but also come with a more satisfactory outcome. This study therefore provided psychometric properties of one of such measuring scales: Stage of Change Readiness and Treatment Eagerness Scale version 8 (SOCRATES-8) and the accompanying change in resilience among Nigerians using psychoactive substances. Participants were 111 psychoactive substance dependent users in three treatment centers in Northern Nigeria. All respondents filled sociodemographic questionnaire, SOCRATES-8 and 14-item Resilience Scale. The study found overall motivation for change among participants to be medium on the three subscales of SOCRATES-8: ambivalence (median=14.00; range=7-20); recognition (median=31.00; range=7-35); and taking steps (median=35.00; range=12-40). More than half (61.3%) scored moderately on resilience. The Internal reliability of SOCRATES-8's subscales fell into acceptable range (ambivalence=0.54; recognition=0.87; taking steps=0.84). Pearson correlation coefficients of subscales with resilience are positive and in moderate range except for ambivalence with very low coefficient. Hierarchical cluster analysis based on participants' resilience characteristics yields five distinct profiles corresponding to five stages of motivational change. ANOVA of these five profiles based on SOCRATES' 3 subscales was significant. The study demonstrates utility of SOCRATES-8 to assess change readiness and treatment eagerness of psychoactive substance abusers according to stages of change and their resilience characteristics. This will aid treatment planning and can also measure treatment outcome. PMID:26298400

    G.M., Bubou; A.C., Brent; C., Tredoux.

    Full Text Available Unresolved social issues between the local community and the petroleum industry plague the Niger Delta Region of Nigeria. These concerns are addressed by introducing a social sustainability assessment framework for the petroleum industry. Key performance indicators (KPIs) are identified, through a s [...] takeholders' engagement process, for social performance measurement purposes. A five-year time-frame is proposed for the periodic assessment of the state of social sustainability. It is recommended that the petroleum industry make the accounting of social sustainability performance measures a priority before beginning projects, especially greenfield projects, since this can assist in resolving the volatility in the region.

    Measurements of activity concentrations of natural radionuclides in and around Obajana cement factory, North Central Nigeria have been carried out in this study to determine the activity levels of natural radionuclides in different environmental matrices in order to assess the radiological health hazards associated with the use of these matrices by the local population. A low-background Pb-shielded gamma spectroscopic counting assembly utilizing NaI (Tl) detector was employed for the measurements. The results show that sediment samples have the highest activity concentrations of all the radionuclides relative to soil, farmland soil, and rock samples. The radium equivalent activity and indoor gamma dose rates together with the corresponding annual effective indoor doses evaluated were found to be lower than their permissible limits. It suffices to say, that contrary to age-long fear of radiation risks to the population in the vicinity of the cement factory, no excessive radiological health hazards either indoors and/or outdoors is envisaged. Therefore, the environmental matrices around the factory could be used without any restrictions. PMID:26150688

The purpose of technology in teacher training is to provide pre-service teachers with the capability of integrating computer technologies into curriculum and instructional activities.This study therefore assessed the internet facilities among pre-service teachers in the University of Ilorin in Nigeria. The use of internet facilities based on gender was also examined. The instrument used was a questionnaire. All pre-service teachers in the Faculty of Education, University of Ilorin were the population for the study. Some 150 students in 400 level were randomly sampled (89 males, 61 females. Frequency counts and percentage were used to answer three research questions while the independent t-test statistic was used to test the hypothesis. The results show that: 80% of the respondents had a positive attitude toward the use of internet facilities, 62% agreed that males were more internet literate; and there was no significant difference between male and female in the use of internet facilities. Based on the findings, it was recommended that training should be emphasized for pre-service teachers, female pre-service teachers should be encouraged to be part of change and pre-service teachers should learn to balance their time.

    Full Text Available Measurements of activity concentrations of natural radionuclides in and around Obajana cement factory, North Central Nigeria have been carried out in this study to determine the activity levels of natural radionuclides in different environmental matrices in order to assess the radiological health hazards associated with the use of these matrices by the local population. A low-background Pb-shielded gamma spectroscopic counting assembly utilizing NaI (Tl detector was employed for the measurements. The results show that sediment samples have the highest activity concentrations of all the radionuclides relative to soil, farmland soil, and rock samples. The radium equivalent activity and indoor gamma dose rates together with the corresponding annual effective indoor doses evaluated were found to be lower than their permissible limits. It suffices to say, that contrary to age-long fear of radiation risks to the population in the vicinity of the cement factory, no excessive radiological health hazards either indoors and/or outdoors is envisaged. Therefore, the environmental matrices around the factory could be used without any restrictions.

    Full Text Available An assessment of the geological and geotechnical parameters as causative agents in the formation of gullies in Wuro Bayare area of northeastern Nigeria is presented. Field geological study of the study area revealed that the area is underlain by basement rocks. The soils in the area are product of in-situ weathering of the underlying basement rocks. The results of sieve analysis shows that the soils at the gully sites have sorting values ranging between 0.42 and 2.3, coefficient of uniformity values ranging between 0.02 and 200, coefficient of curvature values ranging between 0.0125 and 0.23 and also the constanthydraulic values (Kvalues is use to know the bottom erosion ranges. These indicate that the soils are poorly to well-sorted in places. The plasticity indices values ranges between 9.9 and 5.5 with a mean value of about 20 indicates soils of moderate to highly plasticity, slight dry strength and easily friable. Values of Maximum Dry Density (MDD ranging between 2.15 and1.83 g/cm3 at Optimum Moisture Contents (OMC of between 12.4 and 6.4% reveals that the soils were generally lose. From the geotechnical analysis results, commendations for erosions control such as; construction of drainages, grouting concrete rip-raps and afforestation were suggested.

    International Nuclear Information System (INIS)

    Gamma-ray spectrometric measurements were carried out on sediment samples collected from an oil producing field in Oporoma, Bayelsa State, Nigeria, using HPGe detector with the aim of assessing radiological exposure and doses to workers and general public. The activity concentration of 40K varied from (58.21±4.95 - 127.07±10.90) Bq/kg whereas that of 238U varied from (5.67±0.72 - 26.46±2.21) Bq/kg and that of 232Th varied from (5.88±0.61 - 68.51±5.10) Bq/kg. The radiological hazards due to natural radioactivity in samples were inferred from radium equivalent activities which ranges between (22.68 - 133.64) Bq/kg, internal and external indices ranges from (0.08 - 0.43) Bq/kg and (0.06 - 0.36) Bq/kg respectively, and effective dose rate from external exposure to terrestrial radionuclides (40K, 238Uand 232Th ) ranges from (0.01 - 0.38) mSv/y. The values obtained are lower than the internationally recommended limits. The values obtained will not pose any immediate radiological health hazard to the communities within this environment.

    Full Text Available This study was carried out to assess farm households’ food security and consumption indices. The study was conducted in Kaduna state, Nigeria. Data used for this study was collected from a total of 244 farm households with the use of structured questionnaire using a multistage random and purposive sampling technique. The main tools of analysis for this study include descriptive statistics and food security index. The study shows that about one third of the rural farm households sampled was food insecure and that the average farm size of the farm households was 2.05ha as food secure and insecure households cultivate 2.09ha and 1.96ha respectively. Average farm and non-farm income were $1,130.7 and $810.3 per annum respectively as household daily calorie consumed was found to exceed household daily calorie requirement. The food security indices for the food secure and insecure households were found to be 1.462 and 0.852 respectively. Large family size was found to lower available calorie intake of households. The study recommends the need for family planning education and policy frames to increase household farm size.

    Full Text Available The study assessed the use of indigenous maize storage practices among farmers in Anambra State, Nigeria. Data for the study was collected by the use of interview schedule from a sample of 60 respondents. Percentage, mean score and standard deviation were used for analyzing data collected for the study. Results revealed that the farmers were using indigenous technologies such as baskets, aerial (over fire in the kitchen, bare floors, among others in storing maize. The respondents indicated that they stored maize cobs undehusked in order to overcome wastage and obtained information about indigenous storage of maize from parents and fellow farmers. Major problems militating against effective storage of maize include: attack of pests such as rodents and weevils, diseases, termite attack and use of poor quality storage materials. The respondents indicated that use of materials free from termite, clearing of surroundings against fire disaster; use of durable materials treated with insecticides will help to solve the problems. The study recommends that provision of appropriate and affordable storage structures should be made available to the maize farmers in order to avoid wasting of the produce under storage. This will help to ensure food security among rural farm households.

    Full Text Available The study aims at assessing Basil’s genetic phenotypic variability and viral disease incidence in Nigeria for sustainable pathological interventions. Basil (Ocimum basilicum is important for it’s medicinal and nutritive value. It is highly adaptable as a potential crop in the tropics and could therefore enhance the food security of sub Saharan Africa nations. Germplasm seed evaluation and characterization was therefore carried out from the nationwide National Horticultural Research Institute (NIHORT seed collection survey to expand NIHORT basil genetic base. The field layout was completely randomized design with five replications. The treatments were: O. basilicum, O. gratissimum and the local basil. Treatments were randomly allocated per replication. There were significant phenotypic differences in the O. basilicum variety. These differences were observed in the plant coloration ranging from deep to light purple coloration of stem, leaf, leaf vein and petiole. Our observations also revealed for the first time significant tolerance to Venial Mottle Mosaic Virus (VMMV in the purple colored compared to the green O. basilicum in the early stages of growth till 50% anthesis. This is the first report of this observation in the African continent. Tolerance to VMMV symptoms increased significantly (LSD 5% with purplish coloration. We concluded that inducement of purplish coloration in Basil through breeding might improve tolerance to VMMV and thereby increase market value of Basil with sustainable pathological interventions.

    Full Text Available Internally displaced persons are faced with several problems, such as sexual violence, and deserve appropriate intervention, especially in view of the increasing prevalence of HIV/AIDS and other infections in Nigeria. This study attempts to assess interventions offered by governmental authorities and organizations to internally displaced persons and to identify gaps in services as well as to identify what needs to be strengthened. Method: The author reviewed relevant published and unpublished documents and collected data by interviews with semi-structured questions. Twenty-five organizations and government and police departments and 55 internally displaced persons were interviewed. Results: None of the organizations, including governmental institutions, provided social services or assistance in prevention of HIV/AIDS to internally displaced persons. The main services provided by 17 (68% organizations to 43 (78.2% of internally displaced persons were provision of food, clothing and money, but these were provided on an ad hoc basis. Only 3 organizations (12% included spiritual counseling and resolution of communal conflicts in their services. Conclusion: The fact that most organizations, including the government, do not have services for internally displaced persons indicates lack of support for internally displaced persons. The government should be urged to include these people in most prevention services, including HIV/AIDS prevention and treatment. This should help reduce the national prevalence of HIV/AIDS.

    2007-12-01

    Full Text Available In most rural settlements in Nigeria, access to clean and potable water is a great challenge, resulting in water borne diseases. The aim of this study was to assess the levels of some physical, chemical, biochemical and microbial water quality parameters in twelve hand – dug wells in a typical rural area (Igbora of southwest region of the country. Seasonal variations and proximity to pollution sources (municipal waste dumps and defecation sites were also examined. Parameters were determined using standard procedures. All parameters were detected up to 200 m from pollution source and most of them increased in concentration during the rainy season over the dry periods, pointing to infiltrations from storm water. Coliform population, Pb, NO3- and Cd in most cases, exceeded the World Health Organization recommended thresholds for potable water. Effect of distance from pollution sources was more pronounced on fecal and total coliform counts, which decreased with increasing distance from waste dumps. The qualities of the well water samples were therefore not suitable for human consumption without adequate treatment. Regular monitoring of groundwater quality, abolishment of unhealthy waste disposal practices and introduction of modern techniques are recommended.

    2012-03-01

    Full Text Available  Objectives: During infancy and early childhood, the spleencommonly enlarges in patients with sickle cell anemia (SCA, and it thereafter undergoes progressive atrophy due to repeated episodes of vaso-occlusion and infarction, leading to autosplenectomy in adult life. However, this may not always be the case as some studies have reported splenomegaly persisting into adult life. This study aims to determine and review the prevalence of autosplenectomy by abdominal ultrasonography in sickle cell anemic patients in Zaria, Nigeria.Methods: An ex-post-facto cross study of 74 subjects was carried out between May to July in 2010. Hematological parameters were determined by an analyzer while B mode Ultrasonography was used to determine the craniocaudal length of the spleen, if visualized.Results: The mean age of the sickle cell subjects was 23.2 ±5.3 years, while that of the controls was 22.7±12.4 years. Of the 74 sickle cell subjects, 55.4?0were females; while of the 20 controls,50?0were females. Forty one subjects (55.4?20had autosplenectomy and a significant difference existed in the mean splenic size compared with the control (p<0.0001. Only 3 (4.05?20subjects had splenomegaly, while 23 (31?20had a shrunken spleen.Conclusion: Anatomical autosplenectomy is not an uncommon finding in SCA patients. This may be related to inadequate clinical care due to the lack of good health education, ignorance, poverty, and poor standard of care, as well as the lack of newer therapeutic agents.

  16. Geochemical Assessment of Source Rock Qualities Penetrated by Nasara-1 Well (Gongola Basin), Nigeria

    International Nuclear Information System (INIS)

    Nasara-1 is one in a set of 3 exploratory wells drilled in the ] Gongola basin of the upper Benue trough in Nigeria. Nasara-1 well was dry. Organic geochemical studies have been carried out to assess the qualities of source rocks penetrated by the well. The well penetrated entirely Cretaceous sequences of the Pindiga, Yolde and probably Bima formations. Total organic carbon (TOC) contents are generally very low, with none of the values in the siliciclastic sequences exceeding 1.0w%. About 50% of all TOC values lie between 0.50 -0.87wt%. Hydrogen indices (His) correlated against Tmax indicate source qualities that are of entirely gas-generative potential. However, at depths of between 4710- 4770 ft, TOC values of between 55.10 and 55.20wt% characteristic of coals have been recorded; with His of between 564 -589 mgHC/gTOC and Tmax of 423 -4280C. This is the first report of coal deposition in either the Pindiga, Yolde or Bima Formation. Extract yields (SOM) gave values of 360 -447mgHC/gTOC. Petrographic studies on the samples from this interval reported macerals of the amorphous bituminite group, indicating that the very high His and SOM resulted from migration of oil from probably deeper or laterally located yet to be identified source rocks. The total ion chromatograms of the saturated hydrocarbon fractions of the extracts from this interval (4710 -4770ft) show some ramping of unresolved complex mixtures, attributable to biodegradation. Further biomarker data indicate a dominance of low molecular weight n-alkanes (C15 - C25)' pristane/phytane ratios of bewteen 0.8 tp 1.3 and very high contents of C28 regular steranes. These attributes indicate that the source Irock that generated the migrated oil was deposited in a lacustrine environment (C28) with high algal-bacterial contents, whose generated hydrocarbons have been intermittently subjected to anoxic to suboxic biodegradation processes

    2013-09-01

    Full Text Available The study was conducted in Adamawa State, Nigeria. The major thrust of this study is to assess the adoption rate of technology in Fadama III. In its four years of operation, Fadama III project has realized significant impact on household access to new and proven technologies. Adoption rate of technologies among beneficiaries has increased from 43.75% before the inception of the project to 96.255% after the project intervention. This indicates 50% increase against only 20% increase among the non-beneficiaries. Adoption rate of off-farm technologies (agricultural marketing and financial management was also large. The adoption rate for the all the technologies was significant at p = 0.05, except for fish feed formulation, Cold storage, marketing and fish smoking. Yields among respondents have increased significantly due to adoption of proven technologies. The increase was higher among crop farmers (59.38% followed by livestock farmers (48.75%. The increase in yields across all the enterprises has exceeded the set target of 20% increase except for fish production (11.25% and Agro-forestry (6.88%. The increase was more among the beneficiaries compared to non-beneficiaries. It can be concluded that project did not only influence the beneficiaries to adopt technologies for the purpose of improving their socio-economic status but it has also influenced the non-beneficiaries living in Fadama III communities to adopt technologies. Fadama III needs to harmonize existing approaches and need to use complementary systems rather than conflicting ones.

    2012-08-01

    Full Text Available Abstract Background This study assessed lead, cadmium, and nickel level in food crops, fruits and soil samples from Ohaji and Umuagwo and Owerri in South Eastern Nigeria and estimated the potential health risks of metals. Samples were washed, oven-dried at 70–80°C for 24 h and powdered. Samples were digested with perchloric acid and nitric acid. Metals were analysed with Unicam Atomic Absorption Spectrophotometer. Result The concentration of Pb, Cd, and Ni in Ohaji exceeded the maximum allowable concentrations for agricultural soil as recommended by EU. Lead, Cd, and Ni in the food crops were highest in Oryza sativa, Glycine max, and Pentabacta microfila respectively. Highest levels of Pb, Cd, and Ni, in fruits were detected in Canarium schweinfurthii, Citrus reticulata, Ananas comosus respectively. The true lead and cadmium intake for the rice based meal were 3.53 and 0.034 g/kg respectively. Whereas the true intake of lead and cadmium for the cassava based meal were 19.42 and 0.049 g/kg respectively. Conclusion Local food stuff commonly available in South Eastern Nigeria villages may contribute to the body burden of heavy metal. This is of public health importance.

    2008-04-01

    Full Text Available This study focused on the level of penetration of Internet usage among undergraduate students in Nigeria using Obafemi Awolowo University as a case study. Result showed that about 92% of undergraduate students have embraced the Internet and are using it consistently. The online mean time is 3.5hrs/week while on the average, undergraduate experience of Internet usage is about 4years. We found also that the students use the Internet mostly for e-mail, information search and online chatting; all of these were found to have significant impact on their academics and social life. Further analysis revealed that gender attitude is also an important issue; male students appear to use the Internet more than their female counterparts; just as science based students use it more than the non-science based students. The paper therefore recommends appropriate policies for all higher schools of learning in Nigeria to facilitate further diffusion and use of the Internet.

    Full Text Available Abstract Background Women in Nigeria face some of the highest maternal mortality risks in the world. We explore the benefits and cost-effectiveness of individual and integrated packages of interventions to prevent pregnancy-related deaths. Methods We adapt a previously validated maternal mortality model to Nigeria. Model outcomes included clinical events, population measures, costs, and cost-effectiveness ratios. Separate models were adapted to Southwest and Northeast zones using survey-based data. Strategies consisted of improving coverage of effective interventions, and could include improved logistics. Results Increasing family planning was the most effective individual intervention to reduce pregnancy-related mortality, was cost saving in the Southwest zone and cost-effective elsewhere, and prevented nearly 1 in 5 abortion-related deaths. However, with a singular focus on family planning and safe abortion, mortality reduction would plateau below MDG 5. Strategies that could prevent 4 out of 5 maternal deaths included an integrated and stepwise approach that includes increased skilled deliveries, facility births, access to antenatal/postpartum care, improved recognition of referral need, transport, and availability quality of EmOC in addition to family planning and safe abortion. The economic benefits of these strategies ranged from being cost-saving to having incremental cost-effectiveness ratios less than $500 per YLS, well below Nigeria’s per capita GDP. Conclusions Early intensive efforts to improve family planning and control of fertility choices, accompanied by a stepwise effort to scale-up capacity for integrated maternal health services over several years, will save lives and provide equal or greater value than many public health interventions we consider among the most cost-effective (e.g., childhood immunization.

    Full Text Available The challenge of getting maximum performance from employees remain a perennial problem to managers in Nigeria. This challenge is aggravated by the great divide that exist among managers on which of the motivational factors stimulate workers the more into higher performance; while some tilt to monetary incentives; many more argue that non-monetary incentives are major motivating factors. Thus, this study is set to investigate factors that influence workers’ job performance in Nigeria. The study attempt to compare the influence of wages and other conditions service on employees’ performance. To achieve this objective, we elicited information from 300 respondents who were purposively sample from four organizations in some selected geo-political zones in Nigeria. Data collected were presented in graph, pie chart and bar chart. Findings reveal that, employee job performance are greatly influenced by regular and good wages; followed by conducive work environment, availability of internet facilities, good library, recognition/award, regular promotion, training opportunities, access to medical care and communication flow. We made the following recommendations among others, that managers of formal organizations should properly remunerate workers as well as provide conducive work environment for their employees. We posit that other least motivating factors as identified in this study should not ignore by managers, since each provide workers with a level of stimulant that propel them into maximum performance in work organization.

    Pryor, Kenneth L

    2008-01-01

    A suite of products has been developed and evaluated to assess hazards presented by convective downbursts to aircraft in flight derived from the current generation of GOES. The existing suite of GOES microburst products employs the sounder to calculate risk based on conceptual models of favorable environmental profiles for convective downburst generation. Accordingly, a diagnostic nowcasting product, the Microburst Windspeed Potential Index, is designed to infer attributes of a favorable microburst environment. In addition, a GOES-West imager microburst algorithm that employs brightness temperature differences between band 3 (upper level water vapor), band 4 (longwave infrared window), and split window band 5 has been developed to supplement the sounder-derived products. This paper provides an updated assessment of the sounder MWPI and imager microburst algorithms, presents case studies demonstrating effective operational use of the microburst products, and presents validation results for the 2008 convective ...

  1. Habitat assessment for seasonal variation of river pollution in Ibadan, Nigeria, in a geographic information systems interface

    Full Text Available More accurate spatio-temporal predictions of urban environment are needed as a basis for assessing exposure in environmental studies and to inform urban protection policy and management authorities. Using habitat assessment protocol, the author assesses the pollution status of rivers in Ibadan, Nigeria. Data used include hydrographic feature data and habitat assessment data. These basic environmental components are the result of the integration of a wide range of relatively independent factors which enable a more complex analysis of the environment in urban areas. Geographic information systems were used for data management, input and output of data and visualisation. The pollution status of the inland rivers assessed during the rainy season (July to September and dry season (October to March in the eleven local government areas in Ibadan suggested that out of the twenty-two sample points, seven (31.8% and six (27.3% were slightly polluted and nine (40.9% and ten (45.4% were moderately polluted during the rainy and dry seasons, respectively. The environmental models are focused on the assessment of surface-water quality of habitat in relation to human activities. Although the models are calibrated and tested by application in the metropolitan area of Ibadan, the structure of this project is applicable to other similar areas.

  2. Research progress in dynamic security assessment

    Energy Technology Data Exchange (ETDEWEB)

    1982-12-01

    Areas discussed are power system modeling, state estimation, structure decomposition, state forecasting, clustering and security measure development. A detailed dynamic model of a multi-machine power system has been developed. A process state estimator was developed to estimate the long-term dynamic behavior of the power system. The algorithm is identical to the extended Kalman filter but has a modified process noise driving term. A two-stage structure estimation technique was proposed for identifying the power system network configuration. Two approaches to structure decomposition were investigated. A time-scale decomposition of the system equations, based on a singular perturbation approach, was evaluated using a detailed model of a generating system. Spatial decomposition was examined by applying an optimal network decomposition technique to a 39-bus test system. Stochastic approximation based approaches to estimator simplification were examined. Explicit expressions were obtained for the evolution of the first and second moments of the system state. Research into security measures proceeded in three directions. The first area involves viewing the security assessment problem as a hyperplane crossing problem for a stochastic process. The second approach examined the stability of an unforced linear system where the system coefficients are subject to future jumps. The third area of research has led to the formulation of a security measure suitable for on-line assessment of transient stability.

    Full Text Available Background and Purpose: Nigeria is greatly endowed with numerous tree species of which majority of them are native while few are exotic. Report shows that high percentage of man-made forests in the country is dominated with exotic species. This culminated from the assumption that exotic trees are fast growing. However, this study investigated the growth of indigenous trees in tandem with that of exotic species with a purpose to clarify the assumption about the growth and conservation of indigenous species in natural forests. Materials and Methods: The study was conducted at the nursery unit of the Department of Forest Resources Management, University of Ibadan, Nigeria. Five (5 different one year old tree species seedlings were used for the study. Two of the species (Tectona grandis and Gmelina arborea are exotic while the other three species (Khaya senegalensis, Khaya grandifolia and Afzelia africana are native to Nigeria. They were planted on the field in a completely random design and then replicated eight times. Data were collected every month on their height growth, collar diameter and leaf number. Data obtained were subsequently analyzed with ANOVA. Results and Conclusions: Results show that K. grandifolia (45.39 cm grew significantly better (p<0.05 in height than G. arborea (38.11 cm and T. grandis (22.36 cm, while A. africana (40.03 cm closely followed K. grandifolia. Based on the results, the selected indigenous species displayed promising potentials for conservation purpose. Hence, further research in this aspect is encouraged to confirm the findings.

  11. Assessment of public awareness of the detrimental effects of ionizing radiation in Kontagora, Niger State, Nigeria

    International Nuclear Information System (INIS)

    This study investigated the level of public awareness of detrimental effects of ionizing radiation in Nigeria, a case study of Federal College of Education Kontagora Niger State. A total of thirty-five (35) lecturers and seventy-five (75) students were randomly selected from the five schools in the College. The instrument used for data collection was a questionnaire. Data obtained from the questionnaire was analysed using simple percentages. The result of the study revealed that 10 (28.6%) out of 35 lecturers and 32 (42.7%) out of 75 students of the sampled population were totally unaware of ionization radiation and its health detriments. Moreover, the remaining percentage of both lecturers and students had limited knowledge about ionizing radiation and its detrimental effects to humans. The research also shows that a significant percentage of both lecturers and students claimed that the topic 'Ionizing radiations and their health detriments' is not relevant to their field of academic inclination. Based on the findings of the research, it was therefore recommended that the government, Nigeria Nuclear Regulatory Agency (NNRA), physicists and concerned individuals should enlighten the general public on ionizing radiations, its health detriment and safety measures through seminars and the mass media.

    Full Text Available The power sector is critical to the development of any country and Nigeria is no exception, incessant power outrage has been the bane of economic development in the country. For the past three decades, the power sector of the country has been plagued by a lot of problems ranging from low power generation and distribution, decaying facilities most of which were commissioned before and shortly after the country’s independence. The interaction of the electric power industry with climate is manifested both in the effect that severe weather has on the power system and through the contribution of electric power to the production of greenhouse gas (GHG and other pollutants.The paper examines and provides answers to (i the nature of consumers’ attitudes towards power consumption and (ii suggest ways of informing the consumers on the need to conserve power when not in use. This study was carried out in Alimosho Local Government Area of Lagos State, south-west Nigeria. The findings show that 61 percent of electricity consumers’ agreed that rationing of electricity consumption would stabilized the electricity distribution, whereas 39 percent were not in agreement. The study also shows that about 90 percent of the consumers were not satisfied with the services being offered by the Government owned company, while the remaining 10 percent were satisfied. We suggest the authority take to prepaid method of electricity consumption and also intensify efforts to enlighten the public on the need to conserve power.

    Background Research participants may not adequately understand the research in which they agree to enroll. This could be due to a myriad of factors. Such a missing link in the informed consent process contravenes the requirement for an "informed" consent prior to the commencement of research. This study assessed the post consent understanding of Nigerian study participants of the oral health research they were invited to join. Methods A descriptive cross sectional study with research participants who had just consented to one of three ongoing research studies on oral health. Study sites included two centers, one in the northern and one in the southern part of Nigeria. Data were collected using a combination of quantitative and qualitative methods. Results A total of 113 research participants were interviewed. The southern part of the country had 58 respondents with the north having 55. The age range was 21 – 80 years. Mean age was 46.1 (SD16.3). The sample was predominantly male (69.9%) and married (64.6%). There was poor understanding of some key elements of the informed consent process such as involvement in research, benefits, contacts, confidentiality and voluntariness. Some identified factors potentially compromising understanding were poverty, illiteracy, therapeutic misconception and confusion about the dual roles of the Dentist and the researcher. Conclusion The participants recruited into the oral health research in Nigeria did not adequately understand the studies they were invited to join nor do they understand their rights as research participants. Measures should be taken to include research bioethics into the curricula of Dental schools and to train oral health researchers in the country on research ethics. PMID:19646279

    A good quality drinking water is essential for human survival. However, a large percentage of the populations in most developing countries (Nigeria inclusive) do not have access to potable water. This study was therefore conducted to assess the extent of risk arising from consumption of toxic elements in groundwater samples collected from Lagos and Ogun States, Southwest, Nigeria. Twelve toxic elements concentrations (As, Mn, Cd, Cr, Pb, Ni, Al, Ti, V, Hg, Li, and Sn) were determined from 170 groundwater samples using inductively coupled plasma-mass spectrometry, and the physicochemical parameters were determined using standard methods. The pH results revealed that most of the water samples were slightly acidic. Of the twelve toxic elements, only Mn, Cd, Pb, Ni, and Al have concentrations higher than the WHO recommended limit in drinking water. The average dose of Mn and Al consumed daily from groundwater by an adult in Lagos state is 3.4 and 23.2 (?g/kg body weight), respectively. Similarly, an adult in Ogun State consumed an average daily dose of 6.09 and 25 (?g/kg body weight) Mn and Al, respectively. A greater threat was posed to children and infants. The order for risk of cancer in groundwater from Lagos State was Pb > Cr > As > Cd while the order in Ogun State groundwater was Cr > Cd?> As > Pb. The relative high concentrations of Mn, Al, and Pb obtained in this study can be attributed to industrial and anthropogenic activities in the study area. Treatment of groundwater before consumption is recommended to avoid possible adverse cumulative effect. Improved waste disposal methods and regular monitoring of toxic elements in groundwater of the study area should be adopted to safeguard human health. PMID:25971518

    Full Text Available Nigeria has embraced the Open and Distance Learning (ODL mode of education in order to make education affordable and to reach the teaming population of qualified citizens yearning to have quality education but are left out of it. Most universities in the country run the single mode conventional system of education; some run the dual mode while two institutions run the single mode distance education. The groundswell of interest is how computers can best be used to improve the efficiency and effectiveness of the ODL system of education in the country. This led to the assessment of the computer literacy level of the distance learning students who are the beneficiaries of the ODL system in Lagos state. A sample of 858 ODL students from University of Lagos, National Teachers Institute (NTI and National Open University of Nigeria (NOUN were used for the study. A self- developed questionnaire, made up of 15 items was administered to the respondents. The data collected were used to answer four research questions and test one hypothesis. It was found that 54.20% are computer literate; there exists gender differences in the computer literacy with 23.78% female and 30.42% male. There are also age differences. Some of the problems include lack of access to computers, inadequate electricity supply, slow broadband and high cost of internet access. The research hypothesis that there is no significant difference between the observed and the expected computer literacy level of the ODL students in Lagos state was rejected. Based on the results some conclusions and recommendations were made.

    Full Text Available Available sources of portable water for drinking, domestic and industrial chores in Nigeria are dwindling because of concomitant increase in population, urbanization and industrial activities. This study assessed the qualities of Surface Water (SW, Sediment (SD and Tilapia Fish (Oreichromis niloticuss (TF samples collected from Asejire, Oni, Ona, Ogun, Ogunpa, Eleyele and Majidun rivers and Lagos lagoon in south-western Nigeria. Samples of SW, SD and TF were collected at strategic locations from each water source and analyzed using standard procedures. SW for all locations were grossly polluted with organics as indicated by high COD (72.8-292 mg/L and BOD (30.8-143 mg/L and low DO (1.04-6.68 mg/L levels. Lead levels in SW for all locations exceeded WHO and NIS limits for drinking water. Cadmium levels in sediments from Oni, Ona, Ogun and Ogunpa rivers also exceeded Canadian Interim Sediment Quality Guidelines (ISQG of 0.6 mg/kg. Fish from Lagos lagoon were most polluted with Pb, Cr, Ni and Cu. Principal Component analysis showed that 86.4% of overall metal load for SW was from Ogunpa and Eleyele rivers, whereas 62.9% metal load for S was from Ogunpa, Eleyele and Ogun rivers. The metal pollution index order was Pb>Cu>Co>Ni>Cr>Cd. Lead and nickel showed strong positive correlation between SW and SD, suggesting common source while Pb and Cr showed strong negative correlation with Cd between SW and TF. Unsafe disposal practices of wastes into or within the vicinity of water bodies should be discourage.

    There are differences among stakeholders in the indicators they consider as relevant to the assessment of progress. Elucidating these differences can provide useful information about system components and relationships that are important to public support of a CAM program and progress. One of the sources of differences in progress assessments among stakeholders comes from their diverse perceptions about the desired and current states of the social-ecological systems. Stakeholder behavior can be inconsistent between group and individual settings. Individually they may make plans, based on their assessments, that do not conform to the group plan because of their unique interests and preferences. The results of this study need to be further tested. The framework should be used through multiple cycles to determine whether the information gathered with this approach results in additional progress as compared with past approaches. In particular, it would be helpful to test whether gathering such information resulted in a decrease in stakeholders electing to go outside of the CAM process to get their needs met.

This group of service providers are poorly trained and have very limited knowledge about contraception. This paper investigated the nature of the advice offered to simulated current and potential users of oral contraceptive pills. The main objective was to assess the nature and quality of advice provided by PPMVs to pill users. Method: This study is based on findings from a 'mystery client' approach in which three scenarios related to contraceptive pill use were simulated. Each of the 12 mystery clients simulated one of the following three scenarios: new pill users (new to family planning or switching from condom to pills; user seeking a resupply of pills; and dissatisfied pill users intending to discontinue use. Simple random sampling was used to select 410 PPMVs from a total of 1,826 in four states in Nigeria. Qualitative study using in-depth interviews was also conducted. Results: A majority of the PPMVs had pills in stock on the day of the survey and resupplied pills to the clients. PPMVs also understood the reason and importance of referring clients who were new adopters of oral contraceptive methods to a health facility; 30% of the PPMVs referred new adopters to a health facility. However, demand from clients who do not want to go to health care facilities (for various reasons necessitated the provision of oral contraceptive pills to 41% of the first time users. Some PPMVs prescribed treatment to mystery clients who presented with perceived complications arising from the use of pills, while 49% were referred to a health facility. Conclusion: The advice given by PPMVs often falls short of safety guidelines related to the use of oral contraceptive pills. There is a need to continuously update knowledge among the PPMVs to ensure that they provide quality oral contraceptive services as PPMVs bridge the gap between medical experts and users in rural communities.

    Lake Chad holds great importance in Africa. It is a life and income source for millions of people. In Nigeria, Lake Chad gives support for the three largest economic sectors: fishing, farming, and herding. For many centuries, there has been an equitable balance between these sectors and their survival; with the shrinking of the Lake since the 1960’s though, there has been a struggle for these sectors to all maintain a status quo. By performing water quality testing on the streams and rivers that connect with Lake Chad, one is able to determine the health and vitality of the water. Mainly, it has a direct correlation with what the water is providing the land and villages of the area and what the soil and ground are providing to the water. By looking into the conditions of the water which is sourcing a large part of Nigeria, it gives the ability to directly identify actions that are occurring above and below the ground. This gives great support when investigating the shrinking of the Lake. Areas visited and tested in Nigeria include: Kano, Hadejia, Nguru, and Maiduguri. 15 stream regions were visited and tested. In addition to this, 70 villages were visited in which over a hundred well samples were taken. In determining water quality of a sample, specific parameters were tested, these included: nitrate, nitrite, total chlorine, free chlorine, hardness, alkalinity, pH, and conductivity. These tests determined the presence of nitrogen, the hardness, and the acidity/neutrality of the water; all which prove important in helping support and maintain healthy growth and life for those who use and consume it. The information gathered thus far is just a base for future research. Although there are little permanent conclusions drawn from the information gathered, it provides great benefits for future research. Given that this is the first time water quality testing has ever been performed in the area, it gives great foundation for additional water quality testing performed in other regions that sync up to the Lake. Comparisons could then be made thus creating more understanding of the hydrologic functions that occur in the area.

    The concentrations and distributions of organochlorine pesticides (OCPs) in some higher plant samples collected from oil exploration areas of the Niger Delta, Nigeria were examined. The concentrations of ?(25)OCP ranged from 82 to 424, 44 to 200 , 34 to 358, 33 to 106 and 16 to 75 ng/g in Olomoro, Oginni, Uzere, Irri and Calabar plants, respectively. The compositional profiles of the analysed OCPs in most of the plants showed no fresh inputs in the area. The OCPs detected in the samples could have resulted from pesticide usage for intense farming activities cum the use of pesticides to control household pests and insects in the area. Drilling fluids and corrosion inhibitors used in petroleum explorations also have chlorinated compounds as additives thereby serving as potential sources of OCPs. Among the studied plants, elephant grass showed high bioaccumulation and phytoremediation potentials of OCPs. The ?HCH concentrations exceeded the allowable daily intake limit thereby serving as potential threat to humans. PMID:22789817

    Full Text Available In recent times, fish farming (aquaculture has become a major source of income and a substitute for beef in many homes all over Nigeria because a kilogram of fish is cheaper especially the so call ice-fish compare to same kilogram of beef. As a result, many people have embraced fish farming and while some aquaculturist have recorded loss, only few got it right especially at the initial stage of the fish farming business. Some fish farm had average fish weighing a kilogram while others have average weighing less than half a kilogram due to many factors ranging from contamination of pond water from pile up of feeding stuff at bottom of the pond to the use of ground or surface water whose constituents or chemically controlled parameters have adverse effects on harvest in aquaculture. This study was carried out to ascertain the worth or not of surface and groundwater from parts of northern Nigeria for fish farming. Thirty seven surface and groundwater samples were collected during the peak of dry season and analyzed for physicochemical parameter, major and minor elements that can have adverse effects on fish farming using model V-2000 multi-analyte photometer, atomic absorption spectrophotometer, pH and conductivity meter. Some of the measurements were carried out in-situ, while others were carried out in the laboratory. Most of the samples (92% analyzed indicate that they can be used efficiently for aquaculture, only few were observed to have some adverse effects on the intended use and these include pH, salinity, sodium contents and residual sodium carbonate which are closely related to the pH of water samples analyzed. It can be summarized that the studied water samples are generally good for aquaculture.

    Full Text Available This study focuses on the dynamics of urban expansion along with the Landuse/Landcover changes in Ogbomoso North and South LGAs, Oyo State, Nigeria, using Remote Sensing and Geographic Information Systems Technology. Ogbomoso has witnessed remarkable expansion, growth and development of large infrastructural facilities such as highway/expressway, power stations as well as the Ladoke Akintola University of Technology, the University Teaching Hospital Complex, modern markets, very many schools, a number of low cost housing estates, local authority offices, etc. This has therefore, resulted in loss of agricultural land, modification and alterations in the land use/land cover over time without any detailed and comprehensive evaluation of the changes. There is therefore, need for synoptic analyses of patterning, change and expansion at regional scales over time in the environment. LandSat imageries of 1990, 2000 and NigeriaSat-1 imagery of 2007 of the environment were subjected to supervised image classification using IDRISI Selva 17.0 software. Results obtained from classifications were cross-tabulated for change detection. The results reveal that water body appreciated from 1.2% (1990, 3.1% (2000 to 3.7% (2007. Built-up area appreciated from 6.4 to 20.3% (1990-2007. Arable land remained the largest land cover, with the value of 57.8% in 1990, 47.8% in 2000 and 62% in 2007. Compound Interest formula was used to determine the rate of urban expansion of Ogbomoso town and the expansion of the town was projected for the year 2020 and 2025. The average rate of urban expansion of Ogbomoso was found to be significantly high with a value of 8.92%.

    Electricity generation in rural communities is an acute problem militating against socioeconomic well-being of the populace in these communities in developing countries, including Nigeria. In this paper, assessments of wind-energy potential in selected sites from three major geopolitical zones of Nigeria were investigated. For this, daily wind-speed data from Katsina in northern, Warri in southwestern and Calabar in southeastern Nigeria were analysed using the Gumbel and the Weibull probability distributions for assessing wind-energy potential as a renewable/sustainable solution for the country's rural-electrification problems. Results showed that the wind-speed models identified Katsina with higher wind-speed class than both Warri and Calabar that were otherwise identified as low wind-speed sites. However, econometrics of electricity power simulation at different hub heights of low wind-speed turbine systems showed that the cost of electric-power generation in the three study sites was converging to affordable cost per kWh of electric energy from the wind resource at each site. These power simulations identified cost/kWh of electricity generation at Kaduna as €0.0507, at Warri as €0.0774, and at Calabar as €0.0819. These bare positive implications on renewable/sustainable rural electrification in the study sites even as requisite options for promoting utilization of this viable wind-resource energy in the remote communities in the environs of the study sites were suggested.

    Full Text Available ntal Impact Assessment Act of 1992, as well as the Federal Ministry of Environment in 1999. This review study examines Nigeria’s environmental legal framework and the unresolved issues amidst environmental pollution and degradation in the country. Two decades of the EIA Act in Nigeria, the country’s environment is still characterized by ecological problems, unplanned growth and increasing problems of domestic and industrial waste disposal and pollution. Economic development activities, especially in the oil and gas sector, accelerate the loss of topsoil and deforestation, loss of habitat, loss of species and loss of biodiversity, as well as degeneration of wetlands. Water shortages and floods lead to deterioration of urban environmental quality and play a major role in transmission of communicable diseases. Corruption in the water sector is another major player in environmental degradation worldwide, especially in developing countries, including Nigeria. Weak implementation has rendered EIA Act a paper Tiger.

    One hundred and forty five head chefs and catering managers of restaurants in Owerri, Nigeria were surveyed to establish their knowledge of food safety hazards and control measures. Face-to-face interviews were conducted and data collected on their knowledge of risk perception, food handling practices, temperature control, foodborne pathogens, and personal hygiene. Ninety-two percent reported that they cleaned and sanitized food equipment and contact surfaces while 37% engaged in cross-contamination practices. Forty-nine percent reported that they would allow a sick person to handle food. Only 70% reported that they always washed their hands while 6% said that they continued cooking after cracking raw eggs. All respondents said that they washed their hands after handling raw meat, chicken or fish. About 35% lacked knowledge of ideal refrigeration temperature while 6% could not adjust refrigerator temperature. Only 40%, 28%, and 21% had knowledge of Salmonella, E. coli, and Hepatitis A, respectively while 8% and 3% had knowledge of Listeria and Vibrio respectively, as pathogens. Open markets and private bore holes supplied most of their foods and water, respectively. Pearson's Correlation Coefficient analysis revealed almost perfect linear relationship between education and knowledge of pathogens (r = 0.999), cooking school attendance and food safety knowledge (r = 0.992), and class of restaurant and food safety knowledge (r = 0.878). The lack of current knowledge of food safety among restaurant staff highlights increased risk associated with fast foods and restaurants in Owerri. PMID:23917815

    Full Text Available This paper examined principals’ quality assurance strategies in secondary schools in Osun State, Nigeria. The study adopted a descriptive survey research design. Stratified random sampling technique was used to select 10 male and 10 female principals, and 190 male and190 female teachers. ‘Secondary School Principal Quality Assurance Questionnaire’ (SSPQAQ and ‘Students’ Academic Performance Checklist’ (SAPC were used to collect data for the study. The instruments were validated, and test-retest method used to determine their reliabilities yielded 0.74 and 0.71 respectively. One main hypothesis and five operational hypotheses were formulated to guide the study. Descriptive and inferential statistics were used for data analysis. The study further showed that principals’ gender and school location had no significant impact on students’ academic performance. The implication of the findings is that ability of the principals to put in place strategies that would ensure quality in the production of school output is a critical factor in determining school effectiveness. It is against this background that the paper concludes that quality assurance is a function for all stakeholders within the school system. Because it is a management function, the principal should coordinate teachers and other staff members to see that their activities are geared towards ensuring quality in the schools. As part of quality assurance strategies, the principal should recognize the philosophy of education in all aspects of school activities.

    2015-06-01

    Full Text Available This paper studies life cycle environmental impacts and costs of the household cooking sector in Nigeria from 2003 to 2030. Five scenarios are considered: business as usual, dominated by fuel wood stoves; low penetration of improved fuel wood and solar stoves, as planned by the government; high penetration of these stoves; increased use of fossil fuel stoves; and increased use of electric stoves. If business as usual (BAU continues, the environmental impacts would increase by up to four times and costs by up to five times, mainly because of high fuel wood consumption. Implementing the government’s plan to introduce improved fuel wood and solar stoves would yield no environmental advantages, as the proposed number of stoves is too low. A higher number of the advanced stoves would lead to significant improvements in some impacts but would worsen others so that some trade-offs are needed. From the economic perspective, the scenario with a high use of advanced stoves has the lowest total costs but its capital costs are three times higher than for BAU. The government should prioritise the introduction of advanced stoves to reduce health impact from indoor pollution and reduce pressures on biomass resources; however, this may require subsidies. Fossil fuel and electric stoves would also help to preserve biomass and reduce health impacts from indoor pollution but would lead to an increase in greenhouse gas emissions and depletion of fossil resources.

The respondents were satisfied with their respective self-help groups. However, they had some challenges such as inadequate access to extension services (mean = 3.55 and lack of commitment by the leaders (mean = 3.22 and members (mean = 3.19. Educational level and frequency of extension contact of the respondents were found to influence their perception on self-help groups at 5% level of significance. It is recommended that governmental and non-governmental organizations, and university agricultural extension departments should carry out a campaign on workshops for these groups on commitment and extension agencies should diversify their focus to include selfhelp groups and activities.

    International Nuclear Information System (INIS)

    The concentration and distribution of natural radionuclides in marble around Igbeti marble mines (Nigeria)), were measured to evaluate the environmental radioactivity and health effects which the marble samples may posses. The concentration of radionuclides was determined using gamma-ray spectrometry with NaI (Tl) detector. The measured values of the activities of 226Ra, 232Th and 40K in the marble samples were found to lie in the ranges 2.0-2.7, 0.3-1.2 and 5.7-7.3 Bq kg-1, respectively. The samples were also found to have radium equivalent activity in the range 3.4-4.6 Bq kg-1, external hazard indices of 0.009-0.012 and internal hazard indices of 0.014-0.019. The estimated representative (I ?r) hazard index is 0.028. The measurements show that marble samples from Igbeti mine have low level of natural radioactivity and therefore the use of these types of marble in construction of dwellings is safe for inhabitants.

    Full Text Available Abstract Background In response to the growing HIV epidemic in Nigeria, the U.S. Agency for International Development (USAID initiated the VISION Project, which aimed to increase use of family planning, child survival, and HIV/AIDS services. The VISION Project used a mass-media campaign that focused on reproductive health and HIV/AIDS prevention. This paper assesses to what extent program exposure translates into increased awareness and prevention of HIV/AIDS. Methods This analysis is based on data from the 2002 and 2004 Nigeria (Bauchi, Enugu, and Oyo Family Planning and Reproductive Health Surveys, which were conducted among adults living in the VISION Project areas. To correct for endogeneity, two-stage logistic regression is used to investigate the effect of program exposure on 1 discussion of HIV/AIDS with a partner, 2 awareness that consistent condom use reduces HIV risk, and 3 condom use at last intercourse. Results Exposure to the VISION mass media campaign was high: 59%, 47%, and 24% were exposed to at least 1 VISION radio, printed advertisement, or TV program about reproductive health, respectively. The differences in outcome variables between 2002 baseline data and the 2004 follow-up data were small. However, those with high program exposure were almost one and a half (Odds Ratio [O.R.] = 1.47, 95% Confidence Interval [C.I.] 1.01–2.16 times more likely than those with no exposure to have discussed HIV/AIDS with a partner. Those with high program exposure were over twice (O.R. = 2.20, C.I. 1.49–3.25 as likely as those with low exposure to know that condom use can reduce risk of HIV infection. Program exposure had no effect on condom use at last sex. Conclusion The VISION Project reached a large portion of the population and exposure to mass media programs about reproductive health and HIV prevention topics can help increase HIV/AIDS awareness. Programs that target rural populations, females, and unmarried individuals, and disseminate information on where to obtain condoms, are needed to reduce barriers to condom use. Improvements in HIV/AIDS prevention behaviour are likely to require that these programmatic efforts be continued, scaled up, done in conjunction with other interventions, and targeted towards individuals with specific socio-demographic characteristics.

    Mathematical modeling can support the environmental risk assessment and decision making processes. Soil contamination caused by crude oil in the Ogoni region, Nigeria, is qualitatively described in part 1 to understand expected mathematical results. A mathematical-statistical analysis following in part 2 characterizes quantitatively the 33 contaminated sites as entire ecological complex. The single sites are studied in part 3 by classifying multivariate mathematical models to derive precise information about kind and degree of contamination at every surveyed spill site. The geological structure of the Ogoni subsoil and the composition of the upper soil layers are summarized. In this context, the unprotected aquifers are discussed which are essential for the supply of the local population with potable water. The crude oil exploited within and transported through this region for decades will be characterized to understand and interpret results of data processing. Reference will be taken also to the extensive research about negative effects of crude oil contamination on people, fauna and flora. Oil companies have carried out environmental remediation measures, mainly by land farming. These activities are partly unfinished. Therefore, numerous oil spills are still an environmental hazard. In 2007, the Nigerian Federal Government has invited the United Nations Environment Program (UNEP) to explore the remaining crude oil contaminations in the compartments soil and groundwater to prepare final clean-up measures. This project is finished now. The mathematical data processing presented within this three-part contribution will be understood as part of this survey. (orig.)

    Full Text Available This study, “the relevance of feasibility study in assessing the economic viability of dried-sachet tomato production in Kano Metropolis, Nigeria” is carried out using the survey research design. The aim is to find out whether dried-sachet tomato production can be done, profitably and successfully in Kano metropolis. Focus group discussion is used to select some dealers on dried sachet tomato production to determine the viability of tomato business in the study area. Data presentation and analysis was quai-qualitative. The major findings revealed that this product is very important and gives financial benefits apart from its health benefits. Several techniques of removing the liquid contents has been observed as either conventional current, or electrical method by addition of anhydrous (de-hydrating reagents. In order to retain its colour, the convention current method was adopted as the best, that is tray drier, drum drier, mechanized manual method, spray drier etc. Conclusively, the production of dried tomato powder in sachet is a good business, if the necessary capital base is provided. Therefore, it is recommended among others that the experience needed to manage a business should be acquired, and that knowledge and experience acquired should be effectively utilized.

  3. Assessment of viability of exploiting artesian aquifers for municipal water supply in parts of South East Nigeria using isotope techniques

    International Nuclear Information System (INIS)

    The steady growth in Nigeria's population, now about 140 million, and the continuing relocation of many citizens from rural to urban areas in pursuit of higher education and employment opportunities have placed considerable stress on social infrastructures particularly water supply in most of the State Capitals. In parts of the Middle Belt and South East, artesian flows have been encountered in boreholes tapping the False bedded Ajali Sandstone and Upper Coal Measures geological formations. The IAEA sponsored TC Project No. NIR/8/007: 'Isotope-based Investigation of Groundwater in the Middle-Belt and South East' seeks to evaluate the source, recharge and hydrochemistry of these artesian aquifers through study of their hydro-geological setting, hydraulic and hydro-chemical parameters and isotopic compositions of the source water. Inventory of most of the existing artesian boreholes has been completed. Thirty-three water samples have been collected from surface and groundwater sources including artesian and non-artesian boreholes at varying depths, for isotopic and hydro-chemical analysis, which results, when available would be interpreted and discussed in a subsequent paper. This paper reviews the hydro-geology of the project area and outlines the way the project would progress with emphasis on the role isotope hydrology would play in resolving the sustainability question associated with exploitation of the artesian aquifers for municipal water supply schemes. It is envisaged that integrated interpretation of isotopic and hydro-chemical data to be acquired together with baseline data would provide informed advice to Water Resources Managers and Decision-Makers on the viability of planning large scale water supply schemes based on these artesian aquifers.

    Full Text Available Given the specific geographic and spatial location of rural areas in developing countries, to bring agrochemical to the rural farming households, it is argued, may have to come at a cost over and above the normal price it is sold in market. To this end, this work focuses on the willingness of rural farming households to pay more than the mean average regional retail price for agrochemicals in Kwara state, North Central Nigeria. Questionnaire was administered to 100 randomly sampled in the two agricultural development zones (ADP in the study area. Descriptive statistics and the Logistic Binary Regression model were fitted to examine factors that influence respondents’ decision to pay more than the prevailing average prices for access to agrochemicals in the study area. Findings indicated a high level of awareness of agrochemical use and modal responses to quantities used include: fertilizers (41-50Kg/ha, herbicides (<10liters/ha, and pesticides (<10liters/ha on the cultivation of yam, cassava and maize, which were the dominant arable crops in the study area. About 90% of the respondents purchase agrochemicals from their personal savings and less than 10% of the respondents got their agrochemicals from other sources (governmental, developmental agencies, ADP and farmers’ cooperative. Furthermore, 88% (p<0.01 of the respondents indicate willingness to pay more than the current average price to have access to agrochemicals and the logistic regression reveals that level of education (P<0.01, had a positive relationship with respondents’ to willingness to pay more for agrochemicals in the study area. Recommendations were made towards encouraging expanded use of agrochemicals throughenhanced marketing strategies that will facilitate contact of marketing agents to prospective customers located in the rural communities.

    Full Text Available Lead (Pb levels were measured in roadside surface soils, dust particles and rain water samples from the urban cities of Enugu, Awka, Onitsha, Nnewi, Aba, Port Harcourt and Warri in Southern Nigeria in 2007 and 2008. Samples were collected during the dry season, while rain water samples were collected during the early rain (April–June, mid rain (July–August and late rain seasons (September–October for the two years. Soil samples were collected from traffic congested roads, dust was collected by tying a plastic basin on a pole 1.5 m above ground level and leaving it for 45 days. Rain samples were collected from three equidistant points. Samples were analyzed by AAS. The highest soil Pb of 120.00 ± 0.00 and 80.36 ± 0.00 mg/kg were reported in Onitsha for 2007 and 2008, respectively. Nnewi showed 33.40 ± 0.01 and 4,238.29 ± 0.00 mg/kg for 2007 and 2008. Aba had 22.56 ± 0.01 and 21.28 ± 0.00 mg/kg for 2007 and 2008. Higher concentrations were recorded for Nnewi and Port Harcourt in 2008 than in 2007. Enugu had more in 2007 while Awka had more in 2008. Dust Pb ranged from 0.13–0.49 mg/kg and 0.15–0.47 mg/kg for 2007 and 2008, respectively. Rain samples had the least Pb concentration, ranging from 0.103 ± 0.000 to 0.163 ± 0.046 mg/L. We may conclude that Nigerians are exposed to environmental Pb.

    Full Text Available Antiperspirants are astringent substances applied to the skin to reduce or prevent sweat. The process of sweating is an important, normal physiological process that enables us excretes excess water and salt from the body. However conditions like hyperhidrosis (excessive sweat led to the need for control of sweat using antiperspirants, although antiperspirants are now used for cosmetic purposes in recent times. This study was conducted to determine the concentration of Aluminium (Al, which is the active ingredient in most antiperspirants and also to determine the presence and concentration of other metals such as Lead (Pb, Cadmium (Cd, Nickel (Ni, Zinc (Zn, and Copper (Cu. Ten (10 brands of antiperspirant samples marketed in Nigeria were purchased. All samples were pre-treated using acid digestion and the concentrations of Al, Pb, Cd, Ni, Zn and Cu were determined using Atomic Absorption Spectrophotometer (AAS(Perkin Elmer A Analyst 200.Germany. For all the antiperspirant samples analysed, metals such a Cd, Ni, Zn and Cu were not detected while the concentrations of Al and Pb found were between (0.624 – 2.416mg/L and (1.787 – 5.610mg/L respectively. In comparison to the standard permissible limits of aluminium in antiperspirants, the percentage of aluminium in all the samples analysed was within the standard permissible limit set by the United States Food and Drug Administration (FDA. Nine samples conformed to over the counter antiperspirants value while one conformed to a prescription antiperspirant value. However, the presence of lead metal in the antiperspirant samples may be a health risk to the consumers.

    Two commonly used metrics for assessing progress toward universal health coverage involve assessing citizens' rights to health care and counting the number of people who are in a financial protection scheme that safeguards them from high health care payments. On these metrics most countries in Latin America have already "reached" universal health coverage. Neither metric indicates, however, whether a country has achieved universal health coverage in the now commonly accepted sense of the term: that everyone-irrespective of their ability to pay-gets the health services they need without suffering undue financial hardship. We operationalized a framework proposed by the World Bank and the World Health Organization to monitor progress under this definition and then constructed an overall index of universal health coverage achievement. We applied the approach using data from 112 household surveys from 1990 to 2013 for all twenty Latin American countries. No country has achieved a perfect universal health coverage score, but some countries (including those with more integrated health systems) fare better than others. All countries except one improved in overall universal health coverage over the time period analyzed. PMID:26438747

  10. Geotechnical and geochemical assessments of shales in Anambra basin, SE-Nigeria as compacted clay liner in landfill system

    International Nuclear Information System (INIS)

    Document available in extended abstract form only. A major constraint to the development of properly engineered landfills is the high cost of synthetic liners and its scarcity in the local markets in developing country like Nigeria, which calls for alternative local materials for landfill liner. Consequently, crushed shale / clay shale deposits appear inexpensive and can be utilized to effectively retard the spread of leachate from landfills. Hence, this study focus on the assessment of geotechnical, geochemical and sorption characteristics of shale units from Anambra Basin, SE-Nigeria for suitability or otherwise as compacted clay liner (CCL) in landfills. Twelve samples consisting of three each from four different formations namely: Enugu, Nkporo, Imo and Ameki formations were collected and subjected to basic geotechnical tests such as grain size analysis, Atterberg's limits, compaction and coefficient of permeability following standard testing methods (BS 1377). In addition, mineralogical X-ray Diffraction (XRD) and geochemical ICP-MS / ICP-ES analyses were employed for geochemical characterization. CEC and batch sorption tests with respect to Pb, Ni, Cd, Cu and Zn as contaminant in leachates were also employed for sorption characterization. The results of the geotechnical tests conducted on the shale samples revealed that the crushed shale samples have liquid limit range of 55-79%, percentage fines of 80-93%, percentage clay of 23- 36% and activity of 0.8-2.1, all of which satisfy the basic requirements of clay liners according to the specifications of Daniel, 1993. Samples from Enugu, Nkporo and Imo shale have plasticity index range of 40- 54% which is above the recommended limit of 35% and thus likely to exhibit excessive shrinkage and settlement. However, the laboratory compaction shows maximum dry density of 16.8-18.4 kN/m3 and 17.3- 19.1 kN/m3 respectively for Standard Proctor and Modified AASHTO energy levels which suggests no significant change the density irrespective of the compaction level to be utilized in the field. In addition, the permeability of 2.14 - 9.12 x 10-5cm/s is higher than 1 x 10-7 cm/s recommended for typical isolation barriers, which implies negative impacts in respect of possible attendant contamination of the surrounding soil and groundwater by the leachates. The geochemical analyses of the samples reflect relatively high SiO2 values of 52.1-55.8% compared to Al2O3 of 16.96-27.45% and Fe2O3 of 3.10-7.19%, which suggest the dominance of kaolinite as confirmed by the XRD. Nonetheless, the occurrence of illite in Enugu and Nkporo shales and smectite in Imo shale is a confirmation of the relatively high plasticity indices mentioned earlier and indication of good sorption properties. The CEC of the samples have relatively low value of 2.6 - 5.1 cmol/kg, which is less than the recommended minimum of 10 meq/100 g. The sorption capacity of the samples with respect to Zn, Cu, Pb, Cd and Ni ranges from 24.4 to 34.7 ppm with metal sorption in the order of Zn >Cu > Pb > Cd > Ni. The overall assessment revealed that the metal uptake, CEC and plasticity index of the shale samples are positively correlated suggesting strong influence of the clay mineralogy on the sorption characteristics of the samples. In spite of the observed relatively high permeability and swelling potential as well as moderate good sorption properties, the study shale units could be enhanced to the required specification through appropriate amendment technology. Though the shale units do not generally satisfy the requirements of compacted clay liners, however, based on the sorption characteristics, Enugu, Nkporo and Imo shales can be adequately employed for attenuation of contaminant leachates in double, composite or and multiple lining systems

    Full Text Available The National Open University of Nigeria (NOUN is Nigeria’s only university dedicated to providing education through the use of distance instructional methods. So far, however, the lack of availability and poor distribution of course materials, which underpin instructional delivery at NOUN, continue to be hindrances to achieving the university’s vision and mission. There are delays and difficulties in developing and distributing materials to students and Study Centres. Many pioneer students cannot graduate because of this challenge. This paper examines the process of developing self-instructional course materials at NOUN. It reflects on the challenges associated with the quantity, quality, and timely production of course materials, labelled “the hills, the wills, and the skills” obstacles. The paper concludes that there is a need for better professional development in order to provide efficient ODL delivery.

    Full Text Available Malaria and typhoid fever are among the most endemic diseases in the tropics and are associated with poverty and underdevelopment with significant morbidity and mortality. Both diseases can lead to liver damage if not properly treated. The liver function assessment was therefore conducted on (90 volunteer patients; comprising (30 patients with malaria only, (30 with typhoid only and (30 with malaria-typhoid co-infection randomly selected from Abia State University Teaching Hospital, Aba, Abia State, Nigeria and (20 healthy individuals were used as control. Blood samples collected from these subjects were screened for malaria parasite and Staphylococcus typhi using standard methods. Mean serum levels of ALP (112.55±84.23, AST (31.33±12.80, ALT (23.10±11.84, TB (19.43±5.02, CB (5.91±3.03 and ALP(116.69±48.68, AST (28.33±11.72, ALT (22.8±5.94, TB (19.31±5.84,CB (5.60±2.50 were obtained for those subjects with malaria and typhoid respectively and subjects with malaria-typhoid co-infection recorded the following; ALP (134.33±56.62, AST (33.97±8.43, ALT (24.40±4.37,TB (21.27±2.96,CB (6.58±3.10 while the control subjects had mean serum levels of ALP (71.05±18.18, AST (16.65±7.45, ALT (13.85±6.09,TB (10.05±4.85 and CB (3.00±1.67. These mean values were subjected to a statistical test using students t-test which revealed a significant increase (p<0.05.The results suggest that malaria, typhoid and malaria-typhoid co-infection can elevate ALP, AST, ALT,TB and CB serum levels and can lead to liver damage if not properly treated.

    Full Text Available The study assessed the veterinary extension services rendered by the Kwara State Agricultural Development Project (KWADP to poultry farmers in Kwara State, Nigeria. A two stage sampling procedure produced the sample size of 110 from five villages in the study area. A well structured interview schedule was administered to the respondents to produce data which was analyzed using both descriptive and inferential statistical tools. The study revealed that majority of the poultry farmers in the study area were male (73.3%, aged between 31 and 50 (70.9% and had over 10 years experience in poultry farming (74.5%. Only 17.3% of the farmers had secondary school education. Almost all the respondents (97.35% were aware of the veterinary services of the (KWADP. The frequency of extension contact was monthly for 59.1% of the respondents. The t-test at 1% level of significance revealed significant differences in the means of meat yield and egg yield before and after extension contact. The study concluded that though there was strong level of awareness of the veterinary services of the KWADP and there was evidence of positive impact of the extension contact on productivity, the extension service was not meeting the needs of the farmers in some aspects of poultry production such as facilitating credit facilities for expansion. The study recommended that the frequency of extension contact be improved upon. Lastly, the study suggested that farmers should be encouraged to form or join cooperative societies to brighten their chances of securing rural credit.

    Full Text Available This study was carried out on 621 schoolboys with age range of 12-17 years in Junior and Senior Secondary Schools in Odeda area of Odeda local government in Ogun State, Nigeria. Different anthropometric data were collected from these boys. It was observed from the results that all anthropometric dimensions of the school children increase with their age. Moreover, there exists a little difference between mean values of different anthropometric dimensions between the boys of 12-13 years (2.9% to 8.8%, 14-15 years (1.3% to 9.9%, and 16-17 years (1.4% to 5.5%. But the said differences become much higher (16.2% to 42.4% when the same were compared between the children of 12 years and 17 years. Therefore, it can be said that the design of furniture for the children of 12 years will not match the children of 17 years. If single furniture is designed by considering dimensions of the children from 12 years to 17years, it will also not suit the children of all age groups. Therefore, in the present investigation, all the students have been divided into three combined age groups, e.g., 12-13 years, 14-15 years, and 16-17 years, and the percentile values (5th, 50th and 95th of anthropometric measures, which will be helpful for designing of the classroom furniture.

  15. Assessing progress in the development of safety culture

    International Nuclear Information System (INIS)

    This paper is focussed on the organizational culture and learning processes required for the implementation of all aspects of safety culture. There is no prescriptive formula for improving safety culture. However, some common characteristics and practices are emerging that can be adopted by organizations in order to make progress. The paper refers to some approaches that have been successful in a number of countries. The experience of the international nuclear industry in the development and improvement of safety culture could be extended and found useful in other nuclear activities, irrespective of scale. The examples given of specific practice cover a wide range of activities including analysis of events, the regulatory approach on safety culture, employee participation and safety performance measures. Many of these practices may be relevant to smaller organizations and could contribute to improving safety culture, whatever the size of the organization. The most effective approach is to pursue a range of practices that can be mutually supportive in the development of a progressive safety culture, supported by professional standards, organizational and management commitment. Some guidance is also given on the assessment of safety culture and on the detection of a weakening safety culture. Few suggestions for accelerating the safety culture development and improvement process are also provided. (author)

    The levels of some emerging organic pollutants (EOPs) including endocrine disrupting compounds, pharmaceuticals and personal care products were quantified in surface water of a freshwater ecosystem, the Ikpa River Basin, Nigeria using liquid chromatography/high resolution tandem mass spectrometry (LC-MS/MS). In addition, leachates and storm water samples collected from nearby dumpsites were also analysed to assess the effect on water quality. Seventeen compounds were detected at the nanogramme-per-litre levels and the ecological risks of selected compounds assessed based on predicted no-effect concentrations derived from comparison of toxicity data recorded for green algae, fish and invertebrate with the maximum measured environmental concentrations, to obtain risk quotients. Some of the compounds showed some level of widespread occurrence or persistence. Also, bisphenol A, chloramphenicol, erythromycin, triclocarban and triclosan were the most important EOPs detected in the study area that may pose detrimental effects to the aquatic organisms based on the outcome of the risk assessment.

  17. Assessing progress in the development of safety culture

    International Nuclear Information System (INIS)

    The concept of safety culture was introduced by the International Nuclear Safety Advisory Group (INSAG) in the Summary Report on the Post-Accident Meeting on the Chernobyl Accident in 1986. The concept was further expanded in the 1988 INSAG-3 report, Basic Safety Principles for Nuclear Power Plants, and again in 1991 in the INSAG-4 report. Recognizing the increasing role that safety culture is expected to play in nuclear installations worldwide, the Convention on Nuclear Safety states the Contracting Parties' desire 'to promote an effective nuclear safety culture'. The concept of safety culture is defined in INSAG-4 as follows: Safety culture is that assembly of characteristics and attitudes in organizations and individuals which establishes that, as an overriding priority, nuclear plant safety issues receive the attention warranted by their significance. Safety culture is also an amalgamation of values, standards, morals and norms of acceptable behaviour. These are aimed at maintaining a self disciplined approach to the enhancement of safety beyond legislative and regulatory requirements. Therefore, the safety culture has to be inherent in the thoughts and actions of all the individuals at every level in an organization. The leadership provided by top management is crucial. Safety culture applies to conventional and personal safety as well as nuclear safety. All safety consideration are affected by common points of beliefs, attitudes, behaviour, and cultural differences, closely linked to a shared system of values and standards. The paper poses questions and tries to find answers relative to issues like: - how to assess progress; - specific organizational indicators of a progressive safety culture; - detection of incipient weaknesses in safety culture (organizational issues, employee issues, technology issues); - revitalizing a weakened safety culture; - overall assesment of safety culture; - general evaluation model. In conclusion, there is no consistent and visible prescriptive formula for developing a strong safety culture. However, a prerequisite is genuine and consistent commitment by the top management of an organization to improving safety . Providing this commitment exists, the best recommendation is to due something tangible and visible to improve safety, preferably involving employees from the outset. The choice of practices for developing an improved safety culture should take account of the existing national and organizational culture in order to ensure effective implementation. The importance of the learning process has been emphasized. A mechanism is necessary to ensure that international experience of practices to develop a strong safety culture is shared on a regular and frequent basis. The maintenance and improvement of a safety culture is a process of continuous evolution. Indicators are available to assess positive progress in this evolution and to detect a weakening safety culture. (authors)

  20. Assessment of environmental change and its socio-economic impacts in the mangrove ecological zone of the Niger Delta, Nigeria

    Science.gov (United States)

    James, Godstime Kadiri

    The Niger Delta, located in the central part of Southern Nigeria, is endowed with immense Mangrove resources, estimated to be the fourth largest in the world. The term Mangrove refers to salt tolerant species of trees or shrubs that grow on shores and in estuaries located in the coastal tropics and sub-tropical regions of the world. They support highly productive marine food chains. However, Mangrove ecosystems are in serious decline around the world due to the rapid increase in maritime commerce and exploration of mineral resources in the last few decades. These pressures often have immediate consequences on sensitive coastal environments and can potentially impact future human use of coastal space and resources. This dynamic process presents unique opportunities for research to explore the nature and consequences of these pressures. This dissertation focused on the Mangrove ecological zone of the Niger Delta, where resource exploitation and indigenous use of the environment are in direct conflict with important socio-economic implications. Environmental accounting metrics derived from the Driver-Pressure-State-Impact-Response (DPSIR) framework were used to assess changes in the spatial extent of the Niger Delta Mangrove ecosystem and the socio-economic impacts of the observed changes. Landsat remotely sensed satellite data from the mid-1980s through 2003 was used to assess change in the spatial extent of the Mangrove vegetation in the region. A total of 21,340 hectares of Mangrove forest was determined to be lost over the study period. Field research in the region confirmed that this loss was primarily driven by urbanization and activities of the multinational oil and gas corporations operating in the region. To estimate the socio-economic impacts of the Mangrove loss in the region, neoclassical economic valuation and participatory social valuation approaches were adopted. Results from the economic valuation revealed that the net present value of future income stream discounted over a 30 year period at 20 percent discount rate in 2008 was between 642.20/ha and 2,852.62/ha. Consequently, the welfare loss due to the loss of 21,340 hectares of mangrove was between 13,704,548 and 60,874,911. The study also established, for the first time, the high social value of the Niger Delta Mangroves.

    Full Text Available This study aims to assess the effectiveness of the MDG target as it concerns, the state of education in Abuja Municipal Area Council (AMAC metropolis-Nigeria. One of the educational challenges faced in developing countries is how to know which school to send children to. This is mainly due to lack of detailed information as to, what school offers, what type of education, and at what fee. But with Geospatial Information Systems (GIS providing information about primary and secondary schools, Millennium Development Goals’ (MDGs’ vision of literacy for 15-24 year olds will be achieved. The development of geospatial database information system of primary and secondary schools for Garki and Wuse districts, Abuja, was embarked upon to provide timely, consistent and accurate information to decision makers for use in achieving this particular target of the Millennium Development Goals (MDGs. The delay in achievement of this target is not because governments in developing countries aren’t putting maximum effort, but because these governments are choosing to put the cart before the horse. Sustainable literacy level cannot be achieved without an effective framework charged with the collection, storage, query, analysis and management of the relevant data. What is needed is a system that provides government with data about all educational facilities within required proximity and determines availability of the required facilities. GIS is that decision making technology, which integrates ‘spatially referenced data’ with a problem solving environment. The method employed was to acquire both spatial and attribute data of every primary and secondary school in Garki and Wuse districts. The spatially referenced database was created using Microsoft Access 2007 and ArcGIS 9.2 software. The database was queried and the results of the queries analyzed. The results showed that 60% of the schools didn’t have access to Internet. Twenty-one (21 percent had no library. Sixty-three (63 percent of schools were also found to lack Elementary Science Laboratory as stipulated in the National Policy on Education. It was also observed that, the closest distance between public schools to Area 1 and Wuse Central bus-stops, are 0.769 and 1.15 m, respectively.

    Directory of Open Access Journals (Sweden)

    Peter H. Solomon

    2008-10-01

    Full Text Available The Soviet legacy included courts that were dependent and weak, and whose reform had only just begun. The Yeltsin era witnessed considerable progress in making judges more independent and powerful, but the efforts were seriously constrained by budgetary shortcomings and paralysis in the legislative approval of needed procedural changes. As we shall see, the Putin administration overcame both of these obstacles and at the same time began addressing the thorny question of how to make courts and judges accountable without undue harm to their independence. It also started to address the scepticism about the courts among a significant part of the public, through efforts to improve media coverage, make information about courts more available, and make courts user friendly. While praiseworthy and bound to improve the reality and the perception of the administration of justice overall, these initiatives did not end attempts to exert influence on judges and case outcomes by powerful people (in the public and private sectors or the mechanisms that facilitated their efforts. This essay begins by identifying criteria for assessing the quality of the administration of justice in any country, including in the post-soviet world and suggesting specific markers (usually qualitative connected to each of the criteria developed above. Then, the essay provides an account of relevant policy initiatives in judicial reform undertaken first under Yeltsin and then in the Putin years. The essay goes to provide an assessment of the state of the courts in the Russian federation in 2007 in the light of the criteria and markers supplied in the first section. It concludes with a look to the future, and the identification of crucial markers of change for the post-Putin era.

    Inland valley agro-ecosystems which are a category of wetlands have potential for sustainable crop production relative to uplands. A major challenge to their utilisation in the study area is their heterogeneity in hydrology, morphology, soil types and agro-economy. The study assessed the surface water quality of three typologies of the agro-ecosystems—amphitheatre-like valley-heads (Am), valley-side (VS), and low depression (LD)—for cropping. Surface water of six sites were sampled during the wet and dry seasons. The physicochemical properties and metal concentrations of the samples were analysed. Descriptive statistics and water quality indices were used to assess the suitability of the waters of the agro-ecosystems for cropping. Results showed that the valleys have neutral to slightly alkaline waters. Values of physicochemical parameters are generally within the acceptable range for cropping. The concentration of major cations varied across the inland valley types, but exhibited similar characteristics within each valley. The dominance of the major cations is in the order of Na > Ca > K > Mg. ANOVA results indicated that there is no significant difference in the concentration of heavy metals across the valleys (F = 2.044, p = 0.138, ? = 0.05). Generally, most of the physicochemical parameters and trace metals have low concentrations and are non-toxic to plants. Values of water quality indices (sodium adsorption ratio, soluble sodium percentage, total dissolved solids and permeability index) indicated that the concentrations of minerals in waters across the valley typologies are generally within permissible limits for cropping.

  15. Health impact assessment in China: Emergence, progress and challenges

    International Nuclear Information System (INIS)

    The values, concepts and approaches of health impact assessment (HIA) were outlined in the Gothenburg consensus paper and some industrialized countries have implemented HIA for many years. HIA has played an important role in environmental protection in China, however, the emergence, progress and challenges of HIA in China have not been well described. In this paper, the evolution of HIA in China was analyzed and the challenges of HIA were presented based on the author's experiences. HIA contributed to decision-making for large capital construction projects, such as the Three Gorges Dam project, in its emergence stage. Increasing attention has been given to HIA in recent years due to supportive policies underpinning development of the draft HIA guidelines in 2008. However enormous challenges lie ahead in ensuring the institutionalization of HIA into project, program and policy decision-making process due to limited scope, immature tools and insufficient professionals in HIA practice. HIA should broaden its horizons by encompassing physical, chemical, biological and socio-economic aspects and constant attempts should be made to integrate HIA into the decision-making process, not only for projects and programs but also for policies as well.

    2015-10-01

    Full Text Available Although, groundwater constitutes a major source of water supply especially in developing countries, however wastes generated arising from industrial growth and further complication caused by its indiscriminate disposal have been a major risk to groundwater vulnerability. Hence in this study, preliminary impact assessment of wastewater discharged from paint industry on proximal groundwater regime was carried out. Representative groundwater and effluent samples were collected from locations within the study area, and analyzed in accordance to the American Public Health Association standard methods. The values of the measured concentration of the parameters were compared with regulatory standards for drinking water. The concentrations of Mn2+ , total Fe, Ca2+ , TDS, TSS, total hardness and SO4 2- were mostly higher than the permissible regulatory standards. Total alkalinity values were very low in all the groundwater samples, while the presence of E-coli across all the sampling points indicated wide spread pathogenic contamination. The results showed average lead concentration of 1.18 mg/l compared to the permissible level of 0.01 mg/l. Corresponding higher values of the physicochemical and biological parameters were observed in the discharged effluent samples. The observed high lead concentration have potential toxic consequences, and hence enforcement of localized waste minimization is recommended in order to promote waste recycling, and ensure adequate protection of public health and the environment.

    Full Text Available The aim of this study was to assess the wastewater discharge impact from the University of Lagos campus treatment plant on the lagoon system . In order to achieve this objective water samples were collected from nine sites and analyzed for different wastewater quality variables. The field survey was carried out between July and November in order to capture both the wet and dry seasons. Average removal efficiencies of measured parameters from treated effluents are 26% for Total Dissolved Solids (TDS, 73% for Biological Oxygen Demand (BOD, 65.8% for Chemical Oxygen Demand (COD and 72% for Total Nitrogen (Total N for the wet season campaign. During the dry season average rem oval efficiencies of measured parameters are 54% for TDS, 54% for BOD, 39% for COD and 42% for Total N. These values are lower than values obtained for the wet season except for TDS. Most parameters in effluents exceeded the National Environmental Protection Regulations, Effluent Limitation standards for discharge into river bodies. Average concentrations of TDS, BOD and COD in lagoon water show higher concentrations than in the treated effluent and are above the regulatory requirements. The research recommends further study on the possible influence of water dynamics and sampling methods on water quality of the lagoon. The overall results from this research conclude that the lagoon is being polluted by effluents discharge from the university treatment plant thereby exposing the health of local residents who use it for recreation and for food production purposes.

    Full Text Available Problem statement: Pollution of well water, either from point or non-point sources, has become a thing of health concern both in urban and rural areas. Approach: This study aim at assessing the pollution hazards of groundwater resource by sampling some shallow wells from urban and peri-urban area of Abeokuta. Collected samples were analyzed for water quality parameters using standard procedures. The parameters determined were: Static water level, color, turbidity, temperature, Electrical Conductivity (EC, pH, Total Dissolved Solids (TDS Total Suspended Solids (TSS, Total Solids (TS, total hardness, cations {potassium (K sodium (Na, Calcium (Ca, magnesium (mg, Manganese (Mn, iron (Fe}, anions ?Chloride (Cl-, Nitrate (NO3, Sulphate (SO4, Phosphate (PO4}, heavy metals {lead (Pb, Zinc (Zn, Copper (Cu} and microbiological parameters {Bacteria count and Total Coliform count (TC}. Results: Results were subjected to statistical evaluations using SPSS 15.0 for descriptive statistics and Analysis Of Variance (ANOVA. The mean values of TDS, TS, EC and PO4 were higher in well water collected from urban areas compared to peri-urban areas during wet season. It was also observed that during the dry season, TDS, TSS, TS, EC, Mg, Fe, Cl-, PO4 and total hardness were also higher in samples collected from urban areas relative to peri-urban well water samples. Conclusion: Water quality parameters such as Fe, Pb, NO3, EC, Bacteria count and total coliform have mean values greater than World Health Organization maximum permissible standards for drinking water. Elevated values of these parameters are of great concern to public health when the water from these wells is consumed by people without treatment.

    Full Text Available To assess groundwater quality for domestic and irrigation purposes in Yola Adamawa State during the peak of dry season, groundwater samples were collected for analysis from fifteen boreholes and five hands dug wells that cover twenty wards of the City. The area investigated falls within longitude 12o26' E and Latitude 9o16' N. The groundwater samples collected were analyzed using Atomic Absorption Spectrophotometer (AAS, multi – analyte photometer and flame photometer while interpretation of the results was done by Comparison with the World Health Organization (WHO and the Nigerian Standard for Drinking Water Quality (NSDWQ guidelines for portable water. The pH values ranged from acidic to slightly alkaline 5.5 – 7.4, turbidity recorded 0 – 40NTU with four samples above the limit of 5NTU.TDS and EC recorded values ranged between 17 – 1200mg/l, 129 - 1600µs/cm with two samples each above stipulated limit. The concentrations of the cat ions (Ca, Mg, Na, and K are all found below the guideline of WHO and NSDWQ. Sulphate and bicarbonate recorded value range of 2 – 94.1mg/l and 11 – 630mg/l, which are also below the value of 100mg/l and 1000mg/l set by NSDWQ and WHO standards; however the recorded value of nitrate exceeded the specified limit of 50mg/l in seven water samples. Five water samples are classified as hard water based on the limit of 150mg/l and 500mg/l total hardness classification by the limit under consideration. The concentrations of heavy metals cadmium, lead, chromium, copper, manganese and iron were all found to exceed the WHO and NSDWQ standards. Iron concentration exceeded 0.3mg/l in seventeen water sample, manganese concentration exceeded 0.2mg/l and 0.05mg/l in twelve water samples, lead exceeded the limit of 0.01mg/l in seven water samples, also, chromium and cadmium exceeded limits of 0.05mg/l and 0.003mg/l in four and six water samples, copper exceeded set limit in only one sample while Nickel concentration exceeds in two water samples; others are beyond detection level. In all, concentration of heavy metals in groundwater is in the order Mn >Fe > Pb > Cd > Cr > Cu > Ni. The implication of the elevated levels of heavy metals in some samples of groundwater is a serious cause for concern to public health. Most of the groundwater samples are good and can be used for irrigation with adequate soil management

  11. Radiological assessment of fish samples due to natural radionuclides in river Yobe, Northern Nigeria

    International Nuclear Information System (INIS)

    Assessment of natural radioactivity of some fish samples in river Yobe was conducted, using gamma spectroscopy method with NaI(TI) detector. Radioactivity is phenomenon that leads to production of radiations, whereas radiation is known to trigger or induce cancer. The fish were analyzed to estimate the radioactivity (activity) concentrations due to natural radionuclides 226Ra, 232Th and 40K. The obtained result show that the activity concentration for (226Ra), in all the fish samples collected ranges from 15.23±2.45BqKg-1 to 67.39±2.13BqKg-1 with an average value of 34.13±1.34BqKg-1. That of 232Th, ranges from 42.66±0.81BqKg-1 to 201.18±3.82BqKg-1, and the average value stands at 96.01±3.82BqKg-1. The activity concentration for 40K, ranges between 243.3±1.56 BqKg-1 to 618.2±2.81 BqKg-1 and the average is 413.92±1.7 BqKg-1. This study indicated that average daily intake due to natural activity from the fish is valued at 0.913 Bq/day, 2.577Bq/day and 11.088 Bq/day for 226Ra, 232Th and 40K respectively. This shows that the activity concentration values for fish, shows a promising result with most of the fish activity concentrations been within the acceptable limits. However locations (F02, F07 and F12), fish became outliers with significant values of 112.53?Svy-1, 121.11?Svy-1 and 114.32?Svy-1 effective dose. This could be attributed to variation in geological formations within the river as well as the feeding habits of these fish. The work shows that consumers of fish from River Yobe have no risk of radioactivity ingestion, even though no amount of radiation is assumed to be totally safe.

  12. Assessment of radiological hazards of tin mining and ore processing in Jos, Nigeria

    International Nuclear Information System (INIS)

    On the Jos Plateau were found uncontrolled tailing heaps generated from Tin Mining Activities. To assess the associated radiological hazards, an abandoned tailing dump ground was investigated with the residents as the critical population. The mean activity concentrations of 40K, 226Ra and 232Th in the 60 analyzed soil samples were 1251.7±478.4, 3867.5±1282.7 and 8301.9±2862.6 Bqkg-1, respectively with a mean computed dose rate of 7.2±1.6 ?Gyh-1. An annual mean outdoor effective dose of 8.9±0.9mSvy-1 was estimated. Also the activity concentrations of 40K, 226Ra and 232Th in the 60 control soil samples were 447.0±68.0, 37.4±7.4 and 115.4±16.7 Bqkg-1, respectively with a mean dose rate of 0.11±0.01 ?Gyh-1. To account for the internal exposure, vegetables and root crops commonly grown and consumed in the area were assayed. Six varieties of vegetables and five varieties of root crops were analyzed. An internal annual mean effective dose of 148.98±8.14?Svy-1 was estimated. The verification of dose limit compliance for members of the public demands that: External Dose/Dose Limit + Intake (ingested)/ALI (ingestion) + Intake (inhaled)/ALI (inhalation) ? 1. Based on obtained data above, there is non-compliance with the dose limit, since the first term of the compliance formula is much greater than unity. There is therefore a need for an intervention to prevent radiation over exposure of the members of the public. The calculated cancer mortality risk for external and internal exposure scenarios for 226Ra and 232Th were (1.67±0.33) x 10-6(0.00017%) and (3.41±0.14) x 10-6(0.00034%), respectively. The 226Ra radionuclide contributed about 96.09% of the risk in the external scenario with only 3.09% from the 232Th while in the internal, the 226Ra contributed only 70.38%. The combined external and internal (ingestion) risk is (5.08±0.36) x 10-6/year. (author)

    Kudi, T. M.; Akpoko, J. G.; Abdulsalam, Z.

    The study examines the cotton commodity chain and assessed the share of each actor in the cotton industry and identified the constraints encountered in cotton production, marketing and processing. A sample of thirty cotton producers, 50 traders, 500 agents and 3 ginneries were selected from Funtua Local Government Area of Katsina State using both random and purposive sampling techniques. Both qualitative and quantitative data were collected from the participants using focus group discussion and structured questionnaire during the 2004/2005 cropping season. Analysis of the data was done using descriptive statistics and budgeting technique. The farmersN budget analysis indicated that from an investment cost of N 33,146.00 ha-1, farmers obtained a revenue of N 44,544-00 ha-1, thus making a net income of N 11,398 ha-1, while the agent analysis shows that an agent is paid a commission of N 500.00 ton-1 of seed cotton purchase on behalf of the merchant. The analysis of the tradersN budget revealed that from an investment cost of N 36,746.00 ton-1 of seed cotton purchased, traders` N 41,700.00 (lint + seed) and a net profit of N 4,954.00 ton h-1 of seed cotton. The analysis of the ginnery budget revealed that from one ton of seed cotton processed, a ginnery is making a net profit of N 2,178.00. These analyses indicated that cotton production, marketing and processing under the current price and cost setting is profitable. In spite of the profitability in cotton business, the following problems were identified: adulteration of seed cotton with foreign materials, heterogeneous seeds resale in the market, inappropriate packaging systems, no good prices for improving the quality and no mechanism for ensuring transparency in the quality (trust between actors). There is the need for intensification and expansion of the cotton sector in terms of provision of high quality inputs, clean seed cotton, introduction of jute bags for packaging, introduction of quality control mechanisms and good prices in order to sustain the industry.

    1984-12-01

    Nigeria, the most populous country in Africa, currently has no official population policy; however, recent news releases from the Federal Ministry of Information indicate that efforts to deal with rapid population growth may be forthcouming. Adequate census materials are lacking. In 1984 population size was estimated to be 88 million, and in 1983 the estimated crude birth rate was 48-51/1000, the estimated crude death rate was 16-18/1000, and the population growth rate was approximately 3.0%-3.5%. Other estimates for 1983 placed the infant mortality rate at 134 and life expectancy at 49 years. The total fertility rate observed in a 1981 World Fertility Study was 5.4, but this rate was questioned by investigators, who believe it is too low. World Bank projections, based on the assumption that fertility declines will begin soon, indicate that the population will reach 618 million before stabilizing toward the end of the 21st century. At the present time, only 6% of Nigeria's women of reproductive age use contraception, and most of these women contracept only for spacing purposes. Nigeria, which obtained independence in 1960, is plagued by internal strife between different ethnic groups. The northern region, populated by the Hausa is less developed economically than the southern region. The Ibo, who play a major role in the nation's commerical and government sectors, predominated in the the southeastern region, and the Yoruba are the most populous group in the southwestern region. 1/2 of the population if Muslim, 40% is Christian, and the remaining proportion practices traditional religions. During the 1960s, Nigeria derived 2/3 of it gross national product from agriculture, and especially from the export of cocoa, groundnuts, and palm oil. During the 1970s the economy changed markedly as the country began to exploit its oil reserves. By 1983, agriculture accounted for only 20% of the gross national product, and 98% of the country's total exports of US$11.3 billion were derived from oil. Oil reserves are expected to be exhausted in 15 years. To compensate for this expected loss, an effort was initiated in 1980 to revive the country's deteriorating agricultural sector. In addition, the government instituted educational programs aimed at increasing the supply of skilled labor for industrial development. PMID:12313400

    The objective of this paper is to undertake an in-depth evaluation of deforestation, rainfall and landuse dynamics in Nigeria using a localized hybrid TREES/FAO deforestation model. Forty seven (47) 2002 (October 2001-March, 2002) Landsat 7 scenes covering Nigeria were assembled and processed with 376 ground control points for image rectification, reprojection, conversion to reflectance and mosaicking. We also assembled 250m and 500m Moderate Resolution Imaging Spectroradiometer (MODIS) reflectance data for Nigeria for 2002. Using data from the NigerianSat1 Atlas for 2003, Nigerian Geospatial Data Infrastructure (NGSDI) 2002 and a threshold of 70% /5ha for forest cover, the Landsat and MODIS composites were classified into Rainforest, Swamp Forest, Deciduous Forest and Cropland. The overall accuracy was 88%. We developed a multi-criteria hybrid TREE/FAO model for sampling deforestation rates for 2002, 2008 and 2012 for Nigeria. For 2008 and 2012, NigerianSat1 and other satellite data sources were used to fill gaps or replace data on the scanner error of Landsat7. Accumulated patches of Rainfall Data (0.250 x 0.250) was obtained from Tropical Rainfall Measuring Mission (TRMM) for selected forest samples while land cover data from NGSDI was updated with field work data in other evaluate its relationship with the Remotely sensed data. Deforestation rates stood at 0.33% yr-1, 0.14 yr-1 and 0.17% yr-1 for the Woodland, Rainforest and Deciduous Forest respectively. Estimates for the Swamp Forest could not be effectively computed due to high cloud cover throughout the year. The relationship between forest cover change and rainfall stood at r= 0.21; p?0.05 and r=0.42; p?0.05 for the forest and Savannah zones respectively. Deforestation rate was higher in the Woodland than the Rainforest and Deciduous zones due to the better economic value of the species and the ease of felling these trees with minimal cost and favorable terrain features. The weak relationship between rainfall and forest cover in the Rainforest is associated with its location within the zone of maximum air mass convergence due to the concave landscape structure of the Niger Delta to the Atlantic. Moreover, the Rainforest region is nearly always green throughout the year with a highly variable dry season when there are no clouds; hence variability in rainfall may not affect the rate forest cover change as opposed to the Savannah landscapes where forest cover change is dependent on rainfall or moisture supply. Consequently our results show that deforestation is concentrated along the Forest-Savannah boundary of Nigeria where intensive agriculture, anthropogenic forest fires and shifting cultivation dominate. Our results could not confirm hot deforestation spots (pixels) as indicated by most continental-global scale evaluation of deforestation patches. We are going to develop a multi-criteria decision support system for identifying localized deforestation hot spots for Nigeria.

    Highlights: ? The wind energy potential and economic analysis in selected six locations in north central part of Nigeria are investigated. ? Economical evaluation of the wind energy in the selected sites was made by using the levelised cost method. ? Locations that are suitable electricity generation and small scale applications are identified. - Abstract: In this study, the wind energy potential and economic analysis in selected six locations in north central part of Nigeria were investigated using wind speed data that span between 19 and 37 years measured at 10 m height. The performance of small to medium size commercial wind turbine models were examined and economic evaluation of the wind energy in the selected sites was made by using the levelised cost method. The results showed that the cost of energy production per kWh for the selected sites vary between cents 4.02 and cents 166.79. It was shown that Minna is most viable site while Bida is found to be least among the sites considered. Using three selected wind turbine models (in Minna) as case study, an increase in the escalation rate of operating and maintenance cost from 0% to 10%, lead to an increase in the unit energy cost by about 7%. It was further shown that by increasing the escalation rate of inflation from 0% to 5%, the cost of energy decreases by about 29% while the discount rate (return on investment) decreases from 11.54% to 6.23%.

    2012-11-01

    Full Text Available Unemployment in Nigeria is alarming. Its measurement by statistical authorities does not pose red alert. It has been discovered that the observed situation of unemployment is more serious than what official statistics want us to believe. The aim of this study is to examine unacceptable unemployment rate in Nigeria. Our findings show that labor force in Nigeria grows at more or less a steady rate of 0.3% every year while GDP growth rate at 1984 factor cost grows at 3.5% over a period of 33 years which implies that Nigeria experiences a jobless growth. The causes of unemployment in Nigeria include poor infrastructure, insecurity and non-diversification of the economy and poor educational system that does not readily produce employable graduates. Among other things we have recommended that governments at all levels should partner with the private sector and diversify the economy in order to create jobs.

The method of study involves literature survey of previous work done in Imo River sedimentary basin and other works considered necessary for the study. A total of ten (10 vertical electricity soundings (VES was conducted for data generation using terrameter 300 SAS employing Schlumberger configuration. Aquifer (sands from boreholes within three (3 communities and ten (10 water samples were collected and used for statistical and geochemical analysis. The result shows that the lithology is made of sand, silt sand, clay and shale. Three (3 aquifer systems exits in the area confined, semi confined and unconfined aquifers, these occur as upper (33.5m, middle (82m and lower (102 to 115m aquifers. The lithology comprises 4 to 6 layers with water bearing bed occurring at the fifth layer. Average aquifer thickness measured 38 metres. Multiaquifer system exists in some localities. Hydraulic conductivity values range from 25.6m/day to 28.9m/day, transmissivity ranges from 450.842/day to 111.7m2/day while the storativity values ranges from 0.468 x 10-5 to 1.13 x 10-5, all indicate aquifer of good yield. Aquifer thickness ranges from 12.5 to 45m. The water chemistry is neutral, mildly acidic to mildly alkaline. The underground water is of calcium by carbonate type (CaHCO3 fresh and ideal for consumption, irrigation and laundry industry. None of the constituents fell short of WHO (1984 standard . Environmental pollution is only confined to upper aquifer. It is recommended that the three aquifer horizons can be tapped at the depth range of 18 to 102 metres. Multiple screen should be employed where there are more than one aquifer horizon. It is advisable that down the hole electric logging be conducted prior to the installation of screen. The middle and lower aquifers are preferable. The middle aquifer is ideal for domestic boreholes while the lower aquifer should be developed for community and industrial boreholes.

  8. Impact Assessment of University-Based Rural Youths Agricultural Extension Out-Reach Program in Selected Villages of Kaduna-State, Nigeria

    Joseph Gambo Akpoko

    2007-01-01

    Full Text Available INTRODUCTION The term rural youths is best clarified at the onset, to remove the confusion that continues to exist as the concept of youths. The United Nations (1973 definition of youths as young men and women between the ages of 15 and 24 necessarily excludes many youths in the tradition of Nigerian Societies where the youths are any persons a particular society deems as youths. The notion of youth as a bachelor, still under-going training or looking for first employment as defined by Josue (1986 is unrealistic when applied to Nigeria. For instance, an average Nigerian rural girl of 15 years in some parts of Nigeria is a woman, because she is married and, therefore, cannot technically be classified as a youth, going by Josue’s definition. Also many children under the ages of 18 years in Nigeria are school leavers in the sense that they are never school beginners. Similarly, many people above the ages of 40 years are still under-going training or looking for first employment in Nigeria. Inspite of the obvious limitations of the above definitions, age category appears to be the most objective and widely acceptable definition of the concept of youth (Ekong, 1989; Akinola, 1991. Thus, the concept of youths in this study, is young men and women within the ages of 18 and 30. They are those people who are sufficiently matured, but have not acquired the full rights and successes of independent livelihood. The age 18 years had been conceived as a base from when a person can be said to be sufficiently prepared within a farming community to be gainfully involved on the farm (Kuvlesky, 1976; Toraimiro, 1999. The concern about youths development borders on the fact that they possess abundant physical energies, greater knowledge acquisition propensity and less conservative and, therefore, constitute the most important segment of any community development activities (Jibowo, 1989; Torimiro, 1999. They serve as a reservoir of important labour force which can most easily become leaders in employing and innovating modern techniques than their adults counterparts (FAO/UN, 1990; Torimiro, 1999. For decades, institutions of higher learning have been criticized because they have not responded to the needs of agricultural and rural development. The major criticisms have been on the curricula that seemed incompatible with agricultural education objectives and lack of linkages between educational institutions and rural communities (Apantaku, 2004. The National Agricultural Extension and Research Liaison Services (NAERLS of Ahmadu Bello University, Zaria’s main function is to undertake research into extension methodologies and adoption processes including intensification of the use of mass media. Conscious of those criticisms, the NAERLS has attempted to link up with farmers directly through extension outreach programs. One of such programs is the Rural Youths Extension Program (RUYEP. The major objective of the NAERLS’ RUYEP is to provide technical advisory services that would improve agricultural production and living standards of the youths. Action plans that have been developed and implemented include: formation of rural youths co-operative groups; provision of technical advisory services; provision of necessary production inputs; explore, assist and advise on market locations and current prices in order to increase their income and keep up productive enthusiasm. The RUYEP also implements a special small holder water pump hiring scheme to boost dry season farming amongst the youths (NAERLS, 2004. The main objective of this study was to determine the impact of the NAERLS’ Extension Program on agricultural and income of rural youths. The specific objectives of the study were to identify demographic characteristics of the participants and non-participants to determine the impact of the Program on crop yields and farmers income and to assess the respondents’ perception of the effectiveness of the Program. It was also hypothesized that participation in the NAERLS’ RUYEP will have significant impact on crop yields a

  12. Natural radionuclide content and radiological assessment of clay soils collected from different sites in Ekiti State, southwestern Nigeria

    International Nuclear Information System (INIS)

    Clay soil samples collected from different sites in Ekiti State, southwestern Nigeria were analysed for their natural radionuclide contents, using the gamma ray spectrometric method. The overall mean activity concentrations of 226Ra, 232Th and 40K obtained in this study were, respectively, 33.6 ± 5.3, 20.1 ± 3.3 and 207.2 ± 113.0 Bq kg-1. The radiological hazards incurred from the use of the clay soil as a component of building materials were estimated through various radiation hazard indices. The results indicate that the values obtained fall below the internationally accepted maximum limits and as such, the use of clay as a building material does not pose any significant radiation hazard to individuals in the study area.

    Full Text Available Six aggregate indices and some soil properties were evaluated to predict potential soil loss in soils of Southeastern Nigeria. Of the aggregate indices tested, dispersion ratio (DR, Wischmeier's erodibility index (K, clay dispersion index (CDI and clay floccula-tion index (CFI ranked higher than geometric mean diameter (GMD and mean-weight diameter (MWD in predicting potential soil loss. Some aggregate indices found to correlate well with soil loss are in order of decreasing predictability CFI>CDI>DR>GMDŁMWD while organic carbon, % clay content and Fe.O. are some soil characteristics that predict the potential of these soils to erode fairly accurately. Dispersion and flocculation are shown to be influenced by metal-organic complexes which often leads to increased potential soil loss.

    Full Text Available The Information Communications Technologies (ICTs are driving development. Their adoption and integration has become imperative for national development. This study investigated for comparison the ICTs literacy levels of boy and girl-students of senior secondary Grade III in Nigeria, using Enugu State as the case study. Although, ICTs literacy levels were generally poor, the boy-students were better all-round than the girl-students in ICTs literacy parameters tested, namely, ability to process words, access the web for browsing and managing web contents, thereby establishing existence of gender digital divide in the system. The implications of the poor literacy levels and the observed gender digital divide for development were given and recommendations were proffered for narrowing the divide.

    Full Text Available The study examined the Landuse and Landcover (LULC dynamics of the central cocoa cultivation area of southwestern Nigeria between 1972 and 2002 using remotely sensed multi-temporal datasets. The datasets are Landsat 1972, 1986, 1991 and 2002 imageries. The datasets were each subjected to supervised classification techniques employing the maximum likelihood classifier using ILWIS software. This implies that field observation for identification and completion of ambiguous features and other details supported by GPS locations was carried out. Seven dominant classes of feature: agro-forest/light forest, built-up area, exposed rock surfaces/bare land, forest reserve, shrub and arable land, ridge forest and water body were identified. A time series analysis of the LULC changes was carried out to provide the necessary understanding of the changes required for policy formulation and decision-making with respect to cocoa production, forest reserve management and landuse planning, control, coordination and budgeting while being mindful of environmental conservation. This indispensable geo-information is yet lacking in the cocoa growing belt of southwestern Nigeria. ArcView software was used to prepare the corresponding time series LULC maps of the study area. The study showed that the forest reserves within the study area reduced at an average rate of 2.78% per year while agro-forest/light forest reduced to 46.39% (i.e., at an average rate of 1.55% per year and, shrub and arable land increased by 323.06% (i.e., at an average rate of 10.77% per year for food production farming to feed the rapidly increasing population between 1972 and 2002.

    2009-01-01

    Recent testing and validation have found that the GOES microburst products are effective in the assessment and short-term forecasting of downburst potential and associated wind gust magnitude. Two products, the GOES sounder Microburst Windspeed Potential Index and the multispectral GOES imager product have demonstrated capability in downburst potential assessment. Each microburst product consists of a set of predictor variables that generates output of expected microburst risk. This paper compares and contrasts the sounder and imager microburst products and outlines the advantages of each product in the nowcasting process. An updated assessment of the sounder MWPI and imager microburst products, case studies demonstrating effective operational use of the microburst products, and validation results for the 2009 convective season over United States Great Plains is presented.

      Non-biased assessment becomes a reality when Information and Communication Technology (ICT) is implemented as a pedagogical tool to augment teacher practice and student learning. This paper details a study that was undertaken at a secondary school in Lithuania involving four educators and 200 pupils between 14 and 18 years of age. Both teachers and pupils reported the positive benefits from use of a computer-based test (CBT) strategy. Multiple practices of learning and a shift from individual to collaborative learning combined to indicate three notable changes resulting from the strategy: (1) a change from an individual to a collaborative responsibility of assessment, (2) a change from an individual to a collective knowledge shaping, and (3) a change from a possibly weighted evaluation to a defined non-biased assessment outcome. Results from the study point to the potentials from CBT applied in education to address future augmented teacher - students' liaisons.

  5. Progress risk assessment of oral premalignant lesions with saliva miRNA analysis

    International Nuclear Information System (INIS)

    Oral cancer develops through multi-stages: from normal to mild (low grade) dysplasia (LGD), moderate dysplasia, and severe (high grade) dysplasia (HGD), to carcinoma in situ (CIS) and finally invasive oral squamous cell carcinomas (OSCC). Clinical and histological assessments are not reliable in predicting which precursor lesions will progress. The aim of this study was to assess the potential of a noninvasive approach to assess progress risk of oral precancerous lesions. We first used microRNA microarray to profile progressing LGD oral premaligant lesions (OPLs) from non-progressing LGD OPLs in order to explore the possible microRNAs deregulated in low grade OPLs which later progressed to HGD or OSCC. We then used RT-qPCR to detect miRNA targets from the microarray results in saliva samples of these patients. We identified a specific miRNA signature that is aberrantly expressed in progressing oral LGD leukoplakias. Similar expression patterns were detected in saliva samples from these patients. These results show promise for using saliva miRNA signature for monitoring of cancer precursor lesions and early detection of disease progression

    Radioactivity measurements have been carried out using gamma-ray spectroscopy to determine the radionuclide concentrations in soil samples in the premises of the Warri Refining and Petrochemical Company located in the Niger Delta region of Nigeria and also in communities around it. The radionuclide contents of the crude oil and petroleum additives were also similarly determined. Results indicate that on the premises used by the company, the ranges of activity concentrations of (40)K, (226)Ra and (228)Th in the soil samples were 261.3-932.3 Bq kg(-1),oil relative to the petroleum additives. The highest outdoor effective dose rate obtained in the study was 47.5 microSv y(-1) for the villages and 35.2 microSv y(-1) within the company premises. These values are less than the world average outdoor value of 70 microSv y(-1) given by UNSCEAR. Overall, it can be concluded that the long duration of refining activities does not seem to have affected radionuclide concentrations in the environment. Measurements also showed that the observed radiation dose rates did not vary significantly from the previously determined Warri City outdoor gamma radiation dose rates, for which the probability of occurrence of any health effects of radiation was judged low. The measurements, therefore, are interpreted to represent baseline radiometric data for future reference and research in the area. PMID:18714134

    This study compares the performance of clinical diagnosis and three laboratory diagnostic methods (thick film microscopy (TFM), rapid diagnostic test (RDT), and polymerase chain reaction (PCR)) for the diagnosis of Plasmodium falciparum in Nigeria. Using clinical criteria, 217 children were recruited into the study out of which 106 (48.8%) were positive by TFM, 84 (38.7%) by RDT, and 125 (57.6%) by PCR. Using a composite reference method generated from the three diagnostic methods, 71 (32.7%) patients were found to be truly infected and 90 (41.5%) truly uninfected, while 56 (25.8%) were misidentified as infected or noninfected. When each of the 3 diagnostic methods was compared with the composite reference, PCR had sensitivity of 97.3%, specificity of 62.5%, positive predictive value (PPV) of 56.8%, and negative predictive value (NPV) of 97.8%; microscopy had sensitivity of 77.2%, specificity of 72%, PPV of 66.9%, and NPV of 81.1%, while RDT had sensitivity of 62.3%, specificity of 87.4%, PPV of 67.7%, and NPV of 84.5%. PCR test performed best among the three methods followed by TFM and RDT in that order. The result of this study shows that clinical diagnosis cannot be relied upon for accurate diagnosis of P. falciparum in endemic areas. PMID:24371538

    Occupational exposure to lead is common among automobile technicians and constitutes 0.9% of total global health burden with a majority of cases in developing countries. The aim of this study was to determine and compare the blood lead levels of automobile technicians in roadside and organised garages in Lagos State, Nigeria. This was a comparative cross-sectional study. Data were collected using interviewer-administered questionnaires. Physical examinations were conducted and blood was analysed for lead using atomic spectrophotometery. Statistical analyses were performed to compare the median blood lead levels of each group using the independent sample (Mann-Whitney U) test. Seventy-three (40.3%) of the organised compared to 59 (34.3%) of the roadside groups had high blood lead levels. The organised group had statistically significant higher median blood lead levels of, 66.0?µg/dL than the roadside 43.5?µg/dL (P < 0.05). There was also statistically significant association between high blood lead levels and abnormal discolouration of the mucosa of the mouth in the organised group. Automobile technicians in organised garages in Lagos have higher prevalence of elevated blood lead levels and higher median levels than the roadside group. Preventive strategies against lead exposures should be instituted by the employers and further actions should be taken to minimize exposures, improve work practices, implement engineering controls (e.g., proper ventilation), and ensure the use of personal protective equipment.

The population of the study comprised all the MFBs in the two selected parts of Delta State. For the sake of convenience, purposive sampling was employed to select six MFBn branches ( three from each part for the study. Ten respondents were randomly selected from each of the MFBs and administered copies of a well structured questionnaire used as instrument for data collection. The study showed that Microfinance service, particularly, those sponsored by government, have resulted in an increased level of credit disbursement and gains in agricultural production and other activities, the effects were short- lived, due to the unsustainable nature of the programme. Microfinance banks should increase the interval between asking for loans repayment and the time of granting the loans as this renders useless the study or verification of the borrower feasibility study, more especially under an inflationary period.

    Computed tomography has been used for assessing structural abnormalities associated with emphysema. It is important to develop a robust CT based imaging biomarker that would allow quantification of emphysema progression in early stage. This paper presents effect of smoking on emphysema progression using annual changes of low attenuation volume (LAV) by each lung lobe acquired from low-dose CT images in longitudinal screening for lung cancer. The percentage of LAV (LAV%) was measured after applying CT value threshold method and small noise reduction. Progression of emphysema was assessed by statistical analysis of the annual changes represented by linear regression of LAV%. This method was applied to 215 participants in lung cancer CT screening for five years (18 nonsmokers, 85 past smokers, and 112 current smokers). The results showed that LAV% is useful to classify current smokers with rapid progression of emphysema (0.2%/year, plung cancer.

In order to assess the potential radiological hazards pose to the environment due to mining activities in southwest Nigeria, the activity concentrations of {sup 40}K, {sup 226}Ra and {sup 232}Th was determined in tailing and sediment from two mines within the study area. The samples were analysed by gamma spectrometry with low background NaI(Tl) detector. The activity concentrations of {sup 40}K, {sup 226}Ra and {sup 232}Th in all the measured samples ranged from 249.66-1459.25 BqKg{sup -1}, 7.62-50.31 Bqkg{sup -1} and 12.68-234.18 Bqkg{sup -1}, respectively in soil while in sediment samples, the values ranged from 241.86-1590.40 Bqkg{sup -1}, 9.86-74.8 Bqkg{sup -1} and 15.47-145.46 Bqkg{sup -1} for {sup 40}K, {sup 226}Ra and {sup 232}Th, respectively. In order to evaluate the radiological hazards due to the concentrations of natural radionuclides in the samples, the radium equivalent activity, external hazard index, absorbed gamma dose rates and the annual effective dose rates were determined. All these hazard indexes have mean values which are higher than the world average values but are all within their acceptable limits. Document available in abstract form only. (authors)

    Full Text Available As a contribution to the promotion of local content policy in the study of petroleum and environment in Nigeria, a bioremediation agent (Ecorem was formulated from local raw materials. Process kinetics to study operation mechanism of the product was subsequently embarked upon. This study was aimed at assessing the impact of the formulation on soil electrical conductivity (SEC as a part study on its effect on soil properties. Influence of product-soil weight ratio on SEC was examined and predictive equations were developed. Result showed that Ecorem increased SEC by 13.43 to 23.03%, improved the original soil status (159.25 ±9.25 µScm-1 by 8.63 to 52.94% and did not render the treated soil saline. The effect also varied with Ecorem – soil weight ratio, giving positive correlations with coefficients of up to 0.967 (p = 0.01; which is a function of petroleum product type. Predictive equations developed showed that for planning remediation project execution using Ecorem; for soil contaminated by petroleum products such as spent engine oil and crude oil, marginal negative errors of 9% and positive error of 2 to 17% should be taken into consideration.

    Heavy metals are known to have a negative impact on human health especially children through oral ingestion. Total metal concentrations were determined in indoor dust from 19 locations consisting of classrooms, living rooms and offices in Ogun State, Nigeria. Digestion and instrumentation reproducibility were validated using certified reference materials (BCR 723 (Road Dust), NIST 2711a (Montana Soil) and NIST SRM 1640e (Trace element in water)). The measured and certified values showed good agreement. Potential threat levels using geo-accumulation (Igeo) and human health risk for both children and adult were assessed. The mean Igeo levels for the classified and probable carcinogens is in the order Cd (4.84) > Cr (3.28) > Pb (2.61) > Ni (2.48) > As (1.64) while other elements are in the order Zn (5.41) > Ba (4.86) > Sr (4.38) > Zn (4.27) > V (3.24) > Cu (3.14) > Hg (2.61) ? TI (2.61). For human health risk, ingestion was the main route of exposure followed by dermal uptake and inhalation. Hazard index values for all studied metals were lower than the safe level of 1 while Hg vapor exhibited the highest risk value (0.13) in the case of children. The carcinogenic risk for As, Cd, Co, Cr, Ni and Pb were all within the acceptable level (10-4-10-6), but there was potential carcinogenic risk posed by Cr for both adults and children.

  2. Assessment of progressive deformation on the basis of elastic analysis

    International Nuclear Information System (INIS)

    The behaviour of structures subjected to cyclic loading is complex. The structure may be in inelastic or plastic shakedown state or exhibit the ratchetting phenomenon. For reasons related to operation (functional play), geometric instability (buckling) and damage, it is important to estimate the maximum deformation reached on the structure when 'it stabilizes. A proposed solution to this problem is offered by the rule of the efficiency diagram based on a set of experimental results but, in certain cases, this method is impossible or difficult to apply. In this paper, we propose a general theoretical approach to the efficiency diagram and this will allow us to extend its field of application to cases of structures subjected to null primary loading. For this purpose, we demonstrate that, in certain cases, there is a coupling between primary and secondary loading. A new definition of primary stress, identified with the former definition in simple cases, is proposed. Finally, we will apply this method to structures bitubes and shells at free level, under thermomechanical loading and, therefore, generating secondary stresses liable to work in progressive deformation mode

    This study was carried out to determine the occurrence, prevalence and contributing factors to the incidence of goitre in Yewa north local government area of Ogun state, southwestern Nigeria. To achieve these objectives, soil, water, and cassava tubers were collected from four villages -- Igbogila, Egua, Sawonjo and Imoto and from Lagos (about 250 m to the ocean) as a reference location, in order to determine their iodine concentrations. The results of the analyses indicated a soil mean iodine range of 2.1-5.8 microg g(-1); a cassava mean iodine value of 2.3-3.5 mug g(-1) and a drinking water mean iodine value of generally <1.0 microg L(-1) in all the four villages. These values of iodine in soil and water of the four villages are considered low when compared with the soil iodine value of 7.4 microg g(-1) and water iodine value of 6.1 microg L(-1) obtained from Lagos. The limestone unit of the study area remains an inhibiting factor in the bioavailability of the iodine because of its alkalinity. Statistical analysis has shown that there was significant difference between iodine concentration in the soils and the drinking water, and a correlation between the soil iodine and organic matter content at p < 0.05. The correlation between soil iodine and granulometric fractions occurred at p < 0.01. Potential goitrogens in the commonly consumed cassava products might also have contributed to the prevalence of goitre in the study area. Both the females and the adults (i.e., less mobile groups) were found to be vulnerable to goitre development in these villages. PMID:16237605

    Full Text Available The development of new approaches to teaching of large lecture courses is needed. Today’s classroom has a wide range of students including high-achieving motivated learners, students struggling to understand basic concepts, and learning-challenged students. Many of these students can be lost in large classes under the shadow of the high-achieving extroverted students who dominate classroom question-and-answer sessions. Measuring a student’s understanding and achievement of content standards becomes difficult until an assessment has been done. To close this gap, an audience response system was introduced in an introductory Principles of Microbiology course. This technology specifically addressed the goal of individualizing instruction to the needs of the students. The evaluation of this project indicated an overall positive impact on student learning.?

    This paper explains the achieved level in brown coal classification and petrological brown coal assessment in the GDR. Soft brown coal with 40 to 70% moisture content is macropetrographically classified into lithotypes considering visual properties including color, texture, lamination and xylite content. The standard TGL 15387 shows this lithotype classification. A brown coal classification system into microlithotypes (maceral groups greater than 50 mu m) by using quantitative micropetrographical analysis (QMA) developed by Sontag, Tzschoppe and Christoph is further explained. The analysis includes microphotometrical reflection measurements according to E. Kuenstner (1977) and electronic picture analysis using microscope Densitron equipment. Various graphs and schemes are provided showing the macropetrographic classification system of lithotypes; coal property relations among brown coals, briquets and tar content; petrological briquetting characteristics of European soft brown coals from mines in the GDR, Poland, Hungary, Bulgaria and Yugoslavia; gelification properties of microlithotypes determined by microphotometric reflection measurements; and also selected reflection values for brown coal varieties.

  9. Assessment of external and internal doses due to farming in high background radiation areas in old tin mining localities in Jos-plateau, Nigeria

    International Nuclear Information System (INIS)

    Farming on soils situated in high background radiation areas can result to enhanced radiation exposure scenarios and pathways to humans. To assess the likely levels of exposures, farm soil samples were collected from different farmlands in three old tin mining localities (Bitsichi, Bukuru and Ropp) in Jos Plateau Nigeria, known for high radiations. The soil samples were analyzed for the activity concentrations of 226Ra, 232Th and 40K, using gamma-ray spectroscopy. The outdoor annual effective dose rates were calculated using the activity concentrations of the radionuclides and were found to vary from 0.07 mSv to 2.02 mSv across the three localities. Considering dust generation from soil tillage and inadvertent ingestion of soil particles, the likely internal radiation hazards were estimated using conservative dust and soil loading factors. The total average annual effective dose rates due to 226Ra and 232Th that could result from dust inhalation and ingestion of soil particles were 16.9 ?Sv, 8.1 ?Sv and 8.8 ?Sv, respectively for Bitsichi, Bukuru and Ropp. Though these values are about 5% the outdoor exposures to the farmers in those farms and greater than 1 ?Sv y-1, from the point of view of radiation protection and risk, they are significant. It suffices to say, therefore, that the results of this study will create the possibility of the importance to evaluate the health risk among the farming population and workplace environments which often is not covered by regulations concerning health protection.

  10. Assessment of gamma-radiation profile of oil and gas facilities in selected flow stations in the Niger- Delta region of Nigeria

    International Nuclear Information System (INIS)

    The gamma-radiation profile assessment of some flow stations facilities and their host communities in the Niger Delta region of Nigeria have been carried out. The survey was conducted twice monthly for five months in six flow stations facilities, two each from Delta, Bayelsa and Rivers State insitu, using diligent 50 nuclear radiation monitor and a geographical positioning system (GPS). Readings were taken in 11 facilities in each of the flow stations and the host communities. Measured radiation values in the facilities ranged from 08.00±0.70 Rh-1in Afiesere flow station entrance gate to 25.004.20Rh-1in Adibawa flare knockout vessel, while the flow stations mean exposure rate ranged from 14.821.74Rh-1(6.700.78sv/wk) to 18.602.64Rh-1(8.281.17Sv/wk) with fields mean radiation level of 17.142.22Rh-1. The host communities radiation exposure values obtained were (21.002.10, 17.002.00, 15.00±1.40, 18.00±1.60, 10.00±0.70 and 14.00±1.10)Rh-1 for Emeragha, Ekakpamre, Nedugo, Imirigin, Joinkrama 4, and Egbema community respectively. The radiation levels at gas facilities were observed to be higher than those of oil facilities. The highest average dose equivalent rate obtained is within the safe radiation limit of 20?Sv/wk recommended by UNSCEAR (1993). But the mean radiation levels within these areas investigated are far above the standard background level value of 13.00Rh-1.These result obtained indicate no immediate health hazard but may have some long term health side-effect on the staff working in the facilities, the immediate environment and residents of the host communities. The researchers recommended some proactive measures that may help to reduce radiation pollution in the environment.

    Full Text Available Duchenne muscular dystrophy (DMD, clinically featured as progressive skeletal muscle atrophy with gradual loss of muscle strength and activity abilities, is the most common genetic muscular disease in children throughout the world. The core and continuous characteristic of DMD is motor dysfunction. Motor function assessments of DMD are now focusing on muscle strength, walking ability, range of motion and ability of activities, still without unified standards. Confirming the comprehensive, scientific, reasonable and accurate evaluation tools for DMD assessment is the premise of research in motor developmental rules of DMD, which will help to better understand the motor progress of DMD and to supply evidences for choosing treatment methods, confirming timing of intervention, assessing effect of treatments and designing rehabilitation plans. DOI: 10.3969/j.issn.1672-6731.2015.06.002

    A cross-sectional study was undertaken to collect and assess commonly consumed foods/recipes from the six geopolitical zones in Nigeria for the production of food composition database (FCDB) for dietary assessment. Communities used were selected using a multi-stage sampling plan. Focus group discussions, interviews, recipe documentation, food preparations and literature reviews were employed. Qualitative methods were used to analyse and present data. SWOT (strengths, weaknesses, opportunities, and threats) analysis was used to evaluate the project. A total of 322 recipes were collected out of which 110 were soups. Food consumption patterns across the geographical zones were found to be changing. Variations in recipes and methods of preparation of similar foods were observed. Factors to be considered in the development of a country-specific FCDB were identified. There were challenges with the use of values reported in literature for Nigerian foods. The study justifies the need for a country-specific FCDB that will include traditional recipes. PMID:23601404

    Full Text Available La concentración y distribución de biomarcadores aromáticos en carbones y esquistos de cinco perforaciones en la formación Maastrichtian Mamu de la cuenca de Anambra, en el sureste de Nigeria, fueron analizados a través de un estudio de espectometría cromatográfico y de masa del gas para medir la ma [...] durez termal y la entrada de material orgánico. El estudio está enfocado en las variaciones de la abundancia relativa de naftalinas y fenantrenos, y en los esteroides monoaromáticos y triaromáticos identificados en los fragmentogramas de masas. La trimetinaftalina (TMN) es la más abundante de la familia de las naftalinas mientras el metilfenantreno (MP) es el más abundante de los fenantrenos. El tota de los fenantrenos y sus isómeros fue mayor que el de las naftalinas. La distribución de estos hidrocarbones aromáticos y sus alquilos derivados fue controlada ampliamente por un mecanismo de expulsión selectiva y de la maduración térmica de material orgánico. La baja proporción dibenziotofeno/fenantreno (DBT/PHEN) (0.01-0.06), al igual que las concentraciones mejoradas de 1,2,5-TMN relativas de 1,2,7-TMN indican que la materia orgánica se deriva principalmente de plantas mayores, y del diagrama terniario de los esteroides monoaromáticos C27, C28 y C29 sugiere un tipo III mezclado con tipos II/III de querógenos. El valor calculado de la reflectancia de vitrinita (%Rm) determinado de la proporción de isómeros de metildibenziotofeno (MDR) en los extractos rocosos oscila de 0.51 a 1.43. Estos valores de madurez indican que los extractos de carbones y esquistos son marginalmente maduros para la generación de hidrocarbono. Abstract in english The concentration and distribution of aromatic biomarkers in coals and shales from five boreholes penetrating the Maastrichtian Mamu Formation of the Anambra Basin, southeastern Nigeria, were investigated by gas chromatography-mass spectrometry to assess the thermal maturity and organic matter input [...] . The study focused on the variations of the relative abundances of naphthalenes, phenanthrenes, and monaromatic and triaromatic steroids identified on the mass fragmentograms. Trimethylnaphthalene (TMN) is the most abundant member of the naphthalene family while methylphenanthrene (MP) is the most abundant phenanthrene family member. The total of phenanthrenes and their isomers was greater than that of naphthalenes. The distribution of these aromatic hydrocarbons and their akyl derivatives was strongly controlled by a selective expulsion mechanism and thermal maturation of organic matter. The low dibenzothiophene/phenanthrene (DBT/PHEN) ratios (0.01-0.06), as well as the enhanced concentrations of 1,2,5-TMN relative to 1,2,7- TMN, indicates organic matter derived mainly from higher plants, and the extract ternary plot of C27, C28 and C29 monoaromatic steroids suggests a Type III and mixed Type II/III kerogen. The calculated mean vitrinite reflectance (%Rm), determined from the distributions of the isomers of methyldibenzothiophene ratio (MDR) in the rock extracts, ranged from 0.51 to 1.43. These maturity values indicate that the coal and shale extracts are marginally mature for hydrocarbon generation.

    This report documents the result of the US Department of Energy`s (DOE) Environment, Safety and Health (ES&H) Progress Assessment of the DOE Rocky Flats Plant (RFP) in Golden, Colorado. The assessment, which was conducted during the period of May 17 through May 28, 1993, included a selective review of the ES&H management systems and programs of the responsible DOE Headquarters Program Offices (Defense Programs (DP) and Environmental Restoration and Waste Management (EM)), the DOE Rocky Flats Office (RFO), and the site contractor, EG&G Rocky Flats, Inc. (EG&G). Despite the near constant state of flux under which RFP has been required to operate, the Progress Assessment Team has concluded that significant progress has been made in correcting the deficiencies identified in the 1989 Assessment and in responding responsibly to regulations, and DOE directives and guidance that have been issued since that time. The Team concluded that the improvements have been concentrated in the activities associated with plutonium facilities and in regulatory driven programs. Much remains to be done with respect to implementing on a sitewide basis those management systems that anchor an organization`s pursuit of continuous ES&H improvement. Furthermore the Team concluded that the pace of improvement has been constrained by a combination of factors that have limited the site`s ability to manage change in the pursuit of sitewide ES&H excellence.

    Undoubtedly, poverty reduction has become a front-burner issue in development and business agenda. Since its announcement and defense by its advocates as a potent weapon against poverty, the Bottom of the Pyramid (BoP) concept has been bedeviled by controversies. A major controversy is whether or not Multi-National Corporations (MNCs) can serve the BoP market profitably without further impoverishing the poor. The main objective of this study therefore is to assess if there is market for MNCs ...

  12. GIS and Remote Sensing Applications in the Assessment of Change within a Coastal Environment in the Niger Delta Region of Nigeria

    Directory of Open Access Journals (Sweden)

    2006-03-01

    Full Text Available In the last decades, the Niger Delta region has experienced rapid growth in population and economicv activity with enormous benefits to the adjacent states and the entire Nigerian society. As the region embarks upon an unprecedented phase of economic expansion in the 21st century, it faces several environmental challenges fuelled partly by the pressures caused by human activities such as oil and gas exploration, housing development, and road construction for transportation, economic development and demographic changes. This continued growth has resulted in environmental problems such as coastal wetland loss, habitat degradation, and water pollution, gas flaring, destruction of forest vegetation as well as a host of other issues. This underscores the urgent need to design new approaches for managing remote costal resources in sensitive tropical environments effectively in order to maintain a balance between coastal resource conservation and rapid economic development in developing countries for sustainability. Notwithstanding previous initiatives, there have not been any major efforts in the literature to undertake a remote sensing and GIS based assessment of the growing incidence of environmental change within coastal zone environments of the study area. This project is an attempt to fill that void in the literature by exploring the applications of GIS and remote sensing in a tropical coastal zone environment with emphasis on the environmental impacts of development in the Niger Delta region of Southern Nigeria. To deal with some of the aforementioned issues, several research questions that are of great relevance to the paper have been posed. The questions include, Have there been any changes in the coastal environment of the study area? What are the impacts of the changes? What forces are responsible for the changes? Has there been any major framework in place to deal with the changes? The prime objective of the paper is to provide a novel approach for assessing the state of coastal environments while the second objective seeks a contribution to the literature. The third objective is to provide a decision support tool for coastal resource managers in the assessment of environmental impacts of development in tropical areas. The fourth objective is to assess the extent of change in a tropical ecosystem with the latest advances in geo-spatial information technologies and methods. In terms of methodology, the paper draws from primary and census data sources analyzed with descriptive statistics, GIS techniques and remote sensing. The sections in the paper consist of a review of the major environmental effects and factors associated with the problem: initiatives and mitigation measures. The project offers some recommendations as part of the conservation strategies. In spite of concerted efforts by managers to address the problems, results revel that the study area experienced some significant changes in its coastal environments. These changes are attributed to socio-economic and environmental variables.

  13. Preliminary Assessment of Radiofrequency Radiation Exposure Level, From Mobile Base Stations in Ajaokuta and Environs, Kogi State, Nigeria

    International Nuclear Information System (INIS)

    We present the result of a preliminary assessment of radio-frequency radiation exposure from selected mobile base stations in Ajaokuta environs using radio frequency (RF) meter (electromoge meter). The Power density of RF radiation within a radial distance of 125m was measured. Although values fluctuated due to the influence of unavoidable factors suspected to be interferences from other electromagnetic sources around reference base stations, we show from analysis that radiation exposure level is far below the standard limit (10W/cm2 or 107?W/m2) set by the International Commission on Non-ionizing Radiation Protection (ICNIRP) regulatory agencies. The assessment was done in about ten (10) base stations in Ajaokuta, Kogi state. The position and elevation of the base stations were noted using a global positioning system (GPS) to ascertain the position of such stations on the world map. It was discovered that the limit of exposure to radio frequency radiation set by International Commission on Non-ionizing, Radiation Protection (ICNIRP) of 900MHz band expressed in the same unit as 10W/cm2 or 107?W/m2 was not exceeded, the values were also influenced by some inevitable factors. Positions of most of the stations are sited close to homes.

    Full Text Available The aim of this study is to assess the shallow groundwater quality of Pindiga Gombe area for irrigation and domestic purposes. Fifteen water samples collected from wells tapping shallow aquifer was used. The water samples were analyzed for major cations: Na+, Ca2+, K+ and anions: C-, HCO3-1, SO4 2- and NO3-. The important constituents that influence the water quality for irrigation such as Electrical Conductivity (EC, Total Dissolved Solids (TDS, Sodium Adsorption Ratio (SAR, Magnesium Adsorption Ratio (MAR, Permeability Index (PI, Kellys Ratio (KR, and Residual Sodium Bicarbonate (RSBC were assessed and compared with standard limits. The values of total dissolved solids (<166 mg/L, electrical conductivity (<0.249 ds/m, soluble sodium percentage (2.60 to 38.40%, permeability index (0.19 to 7.40%, magnesium adsorption ratio (37.34 to 66.50%, kellys ratio (0.0004 to 0.029 meq/L, residual sodium bicarbonate (0.35 to 3.02 meq/L and sodium adsorption ratio (0 to 0.035 were found to be within the safe limits and thus largely suitable for irrigation purposes. The groundwater will thus neither cause salinity hazards nor have an adverse effect on the soil properties of the study area. Furthermore, the water samples also fall within the recommended limits and are found suitable for domestic purposes.

    2015-03-01

    The International Society of Rock Mechanics (ISRM) suggested cracked chevron notched Brazilian disc method falls into a major testing category of rock fracture toughness measurement by virtue of chevron notched rock samples. A straight through crack front during the whole fracturing process is assumed in the testing principle but is never assessed. In this study, the progressive rock fracture mechanism of cracked chevron notched Brazilian disc rock specimens is numerically simulated for the first time. Two representative sample types with distinct geometry of notch ligaments are modelled. The assumption of a straight through crack front for chevron notched fracture samples is critically assessed. The results show that not only the notch tip but also the saw-cut chevron notch cracks during the experiments. The straight through crack front assumption is never satisfied in the realistic rock fracture progress of chevron notched disc samples. In addition, the crack features prominent curved front, far from being straight. In contrast to the sample type with narrow notch ligament, the acoustic emission (AE) of the simulation on the sample with wide notch ligament depicts obvious biased fracturing of the prescript fracturing route of the notch. The numerically observed progressive fracture mechanism calls for more attention on how to accurately calibrate the critical dimensionless stress intensity factor for a better measurement of Mode I fracture toughness via chevron notched samples.

  18. Health impact assessment in Australia: A review and directions for progress

    International Nuclear Information System (INIS)

    This article provides an overview of Health Impact Assessment (HIA) within Australia. We discuss the development and current position of HIA and offer some directions for HIA's progression. Since the early 1990s HIA activity in Australia has increased and diversified in application and practice. This article first highlights the emergent streams of HIA practice across environmental, policy and health equity foci, and how these have developed within Australia. The article then provides summaries of current practice provided by each Australian state and territory. We then offer some insight into current issues that require further progression or resolution if HIA is to progress effectively in Australia. This progress rests both on developing broad system support for HIA across government, led by the health sector, and developing system capacity to undertake, commission or review HIAs. We argue that a unified and clear HIA approach is required as a prerequisite to gaining the understanding and support for HIA in the public and private sectors and the wider community.

    Outcome measures for clinical trials in neuromuscular diseases are typically based on physical assessments which are dependent on patient effort, combine the effort of different muscle groups, and may not be sensitive to progression over short trial periods in slow-progressing diseases. We hypothesised that quantitative fat imaging by MRI (Dixon technique) could provide more discriminating quantitative, patient-independent measurements of the progress of muscle fat replacement within individual muscle groups.

    The acquisition and use of mobile phone is tremendously increasing especially in developing countries, but not without a concern. The greater concern among the public is principally over the proximity of mobile base stations (MBS) to residential areas rather than the use of handsets. In this paper, we present an assessment of Radio-Frequency (RF) radiation exposure level measurements and analysis of radiation power density (in \\mu W/sq m) from mobile base stations relative to radial distance (in metre). The minimum average power density from individual base station in the town was about 47\\mu W/sq m while the average maximum was about 1.5mW/sq m. Our result showed that average power density of a base station decreases with increase in distance (from base station) and that radiation intensity varies from one base station to another even at the same distance away. Our result (obtained signature of power density variation) was also compared with the 'expected' signature. It was found that radiation from external...

    2006-01-01

    Full Text Available The study assessed the training needs of fadama farmers in Osun State for future agricultural extension work development. Primary data on fadama farming were collected from 150 fadama farmers selected using random sampling technique. The data were analyzed using descriptive statistics, correlation matrix and regression techniques. The results of analysis indicated that fadama farming is practiced mostly very close to boundaries of major towns and cities. The mean age of fadama farmers was 40 years. Areas of training needs identified by the fadama farmers include: chemical control of insect pest, use of appropriate chemical and correct dose of application; appropriate herbicide to be used to reduce drudgery and storage of fadama produce. The result showed a negative but significant relationship (b = -0.302 between the number of years of formal education and training need expressed by fadama farmers. Also the correlation coefficient showed that size of household (b = 1.230, size of fadama farmland (b = 1.245, hour spent on farm (b = 1.469 and previous fadama trainings attended (b = 7.567 were positive and significant at p=<0.05. The study concluded that extension agents and agencies should design regular training programmes for fadama farmers in the area of deficiencies identified and strengthen fadama associations such that tripartite problems of lack or high cost of inputs, lack of starting and operating capital and fadama land could be reduced/solved.

    Full Text Available Sequel to the increased installation of borehole in Benin City metropolis to meet domestic water need, some residents sunk borehole close to dumpsite. This study was conducted to assess the quality of water from three of such bore holes installed close to dumpsite. Physico-chemical analysis results obtained showed variation in concentration of parameters. The ranges of concentrations of the elements were as follows; pH (5.49 ± 0.05 to 5.78 ± 0.07, EC (136.33 ± 3.15 to 547.00 ± 8.19 µS/cm, temp (25.93 ± 0.42 to 26.57 ± 0.15°C, sulphide (0.70 ± 0.01 to 0.80 ± 0.06 mg/L, NH4-N (0.68 ± 0.05 to 0.76 ± 0.04 mg/L, NO3-N (0.27 ± 0.05 to 0.37 ± 0.01 mg/L, COD (3.70 ± 0.02 to 5.26 ± 0.07 mg/L, BOD (2.73 ± 0.12 to 3.37 ± 0.15 mg/L, NO2-N (0.14 ± 0.02 to 0.06 ± 0.08 mg/L. The parameters obtained showed that there is no underground seepage from leachate to borehole. This may be due to the depth of the borehole and the distance of the borehole from dumpsite which is estimated to be 100 m apart. The parameters detected were below the permissible limits recommended by WHO for drinking water.

  8. Petroleum Business in Nigeria

    International Nuclear Information System (INIS)

    The petroleum industry is vital to the health of the Nigerian economy as it accounts for over 80% of Nigeria's total export earnings and about 70% of total government revenue. Nigeria has an oil reserve base of 21 billion barrels and gas reserve of 120 trillion cubic feet. With natural gas becoming the worlds fastest growing energy resource, the Nigerian Government has put in place a program to grow her oil reserve base to over 25 billion barrels and significantly increase her gas reserves. An earlier commitment made in 1990 to increase Nigeria's oil reserve base from a level of 16 to 20 billion barrels by 1995 was achieved well ahead of time. This success was largely due to financial incentives offered investors. This healthy business climate still prevails. This paper presents the investment opportunities that Nigeria offers genuine investors in both the upstream and downstream sectors of the industry and defines the legal/regulatory requirements for doing business in Nigeria. We try to give an insight into specific government policies that help to create an enabling environment for investors in the upstream and downstream sectors of the petroleum industry. We showcase the 5 (five) major sedimentary basins with enormous oil and gas potential where exploration/exploitation risks are rated medium to low. We focus on the environment and government's efforts to enforce the rules and guidelines that govern the policy termed the Environment, Safety and Standards. We recognize that the business challenges of the third millennium will dictate new alliances and partnerships that will survive and thrive only in a climate that is safe for the investor. This is the business climate we throw open in Nigeria for investors to come in and do business with us

  15. Assessment of NORM-containing food crops/stuffs in OML 58 and OML 61 within the Niger Delta region of Nigeria

    International Nuclear Information System (INIS)

    A preliminary assessment of the levels of natural radionuclide in some commonly consumed cereals, fruits, vegetables and tubers within OML 58 and OML 61 in Niger Delta Region of Nigeria has been carried out. The areas under study were divided into six (6) zones (A,B,C,D,E,F) and investigated. An insitu measurement approach was adopted using Nuclear Radiation Meter (Radarlert-100) and a handheld Global Positioning System (GPS 76 CSX) equipment. Sixteen(16) readings each was taken in each of the six zoned areas making a total of ninety-six (96) food crops samples which was randomly selected. Measured average radiation levels in each of the six zones ranges between 0.009±0.001mRhr-1 (0.479±0.038mSvyr-1) to 0.020±0.001mRhr-1(1.064±0.065mSvyr-1) for zone A, 0.011±0.001mRhr-1, (0.585±0.041mSvyr-1) to 0.022±0.002mRh-1 (1.170±0.105mSvyr-1) for zone B, 0.010±0.001mRhr-1 (0.532±0.048mSvyr-1) to 0.025±0.002mRhr-1 (1.330±0.016mSvyr-1) for zone C, 0.010±0.001mRhr-1(0.532±0.048mSvyr-1) to 0.028±0.002mRhr-1 (1.490±0.134mSvyr-1) for Zone D, 0.005±0.000mRhr-1 (0.266±0.021mSvyr-1) to 0.022±0.002mRhr-1 (1.170±0.105mSvyr-1) for Zone E, 0.01± 0.001mRhr-1(0.532±0.048mSvyr-1) to 0.016±0.001mRhr-1(0.851±0.068mSvyr-1) for Zone F. The mean food crop radiation levels ranges from 0.012±0.001mRhr-1(0.798±0.065mSvyr-1) to 0.016±0.001mRhr-1(0.849±0.067mSvyr-1) while the mean background radiation levels ranges from 0.011±0.001mRhr-1 (0.585±0.041mSvyr-1) to 0.015±0.001mRhr-1(0.798±0.065mSvyr-1). The annual equivalent dose estimated were in the range of 0.613mSvyr-1 to 0.849mSvyr-1 far below the dose limits for radiological workers (20mSvyr-1) and the dose limit for the public (1mSvyr-1) (ICRP,1994). Comparison of the measured radiation levels of the food crops samples with the normal background levels show that 45 samples which represent 46.8% of the whole sample exceeded the normal background level of 0.013mRhr-1 (ICRP,1994). These values obtained will not pose any immediate radiological health hazard to the populace consuming these food crops/stuffs but may have some long-term health side-effects.

    Full Text Available Accidents occurring on mechanized farms have been a thing of concern to farmers and researchers both within and outside Nigeria. An investigation into the causes and prevention of farm accidents on mechanized farm was carried out in Benue, Federal Capital Territory, Kwara, Nasarawa, Niger and Plateau states that constitute the north central zone/states of Nigeria. The data collection instrument was a questionnaire designed and distributed to all the states mentioned. The questionnaire addressed demographic variables and issues linked directly with the types, causes and prevention of farm accidents. A total of 2283 tractors were available in the mechanized farms surveyed, while a total of 1014 constituted other farm machinery/equipment. Results show that 81.7% of accidents victims are male. About 45.5% of the accident victims were aged between 40years and above. About 33.96% of the minor accidents resulted in slight damage to equipment and machinery. Similarly 43.4% of accidents resulted in substantial loss in time, while about 22.64% of accidents resulted in medical attention. There was no attempt made to quantify the monetary terms of the cost of each accidents, as there was dearth of information. The results obtained in this work are in agreement with the previous studies both outside and inside Nigeria. Also, from this survey work, there was a problem of good record keeping in most of the establishment surveyed. It is therefore, recommended among other things that adequate training and retraining of tractors/machinery operators should be carried out periodically, to intimate operators on recent use of farm equipment due to environmental and human factors

    Full Text Available There is no one entity solely responsible for the debt crisis Nigeria found itself in by the early 1980s: not the Nigerian government, the banks, not the creditor governments. The increase in the Nigeria debt crises has been caused by a lot of factors that have forced their way into the country’s administration over the years. The major cause of Nigeria’s debt crises is the change in the economic fortune in the oil sector.One major obstacle for Nigeria’s economic development over the last two decades has been its crippling debt overhang. In April 2006, Nigeria ordered a final debt repayment to rich lending nations, completing Africa’s biggest debt relief deal.How do we assess the debt crisis in which Nigeria found itself? What are the lessons to be learned? Certainly, these are some of the most important questions to be studied as the country embarks with a clean slate with private and bilateral lenders after the long sought-after debt restructuring deal that came in April 2006.This paper analyzes the lessons to be learned from Nigeria’s debt history, looking especially at the phenomenon of oil-led spending and borrowing that occurred during 1986-2006. Its objective is to determine whether Nigeria received a higher credit-rating than its domestic and macroeconomic fundamentals would have otherwise justified due to its oil revenues, and whether the debt-repayment crisis arose because oil windfalls from the early 1980s were not used to retire its debt.

  2. TRADE OPENNESS AND ITS IMPACT ON NIGERIA’S NON-OIL INDUSTRIAL SECTOR: 1979-2009

    Full Text Available The growth of the industrial sector and the resultant export witnessed in Nigeria in the 1960s and 1970s was largely the outcome of a policy of import substitution which precipitated the overvaluation of the domestic currency partly through the encouragement of low return investments by preferential credit policies and direct public investment in industrial ventures. The ‘fait accompli’ adoption of the IMF – induced structural economic reforms whose main trust is trade openness among others was targeted at restructuring the economy away from over dependence on the oil sector. This study focused on the impact of trade openness on Nigeria’s industrial performance with a view to determining the spill over effect of the policy on the major contending sectors in the economy. This study therefore examined the relationship between trade openness and industrial performance,armed with secondary time series data and using an ordinary least square multiple regression analytical method. The study found that the unilateral trade openness of 1986 produced the sustainable impact on the nonoil industrial sector of the Nigerian economy. It was observed that Public domestic investment, saving rate, capacity utilization and infrastructure has negative impacts on Nigeria’s industrial performance. Our findings and conclusion support the need for the government to consolidate and maintain the credibility of the trade policies for sustainable growth and development. More progress will be achieved if the conditions needed for a deregulated trade system to work properly are set in place.

  3. APPLICATION OF WELL LOG ANALYSIS IN ASSESSMENT OF PETROPHYSICAL PARAMETERS AND RESERVOIR CHARACTERIZATION OF WELLS IN THE “OTH” FIELD, ANAMBRA BASIN, SOUTHERN NIGERIA

    Full Text Available Over the past years, the Anambra basin one of Nigeria’s inland basins has recorded significant level of hydrocarbon exploration activities. The basin has been confirmed by several authors from source rock analyses to have the potential for generating hydrocarbon. For the hydrocarbon to be exploited, it is imperative to have a thorough understanding of the reservoir. Computer-assisted log analyses were employed to effectively evaluate the petrophysical parameters such as the shale volume (Vsh, total porosity (TP, effective porosity (EP, water saturation (Sw, and hydrocarbon saturation (Sh. Cross-plots of the petrophysical parameters versus depth were illustrated. Five hydrocarbon bearing reservoirs were delineated in well 1, four in well 2. The reservoirs in well 3 do not contain hydrocarbon. The estimated reservoir porosity varies from 10% to 21% while their permeability values range from 20md to 1400md. The porosity and permeability values suggest that reservoirs are good enough to store and also permit free flow of fluid. The volume of shale (0.05% to 0.35% analysis reveals that the reservoirs range from shaly sand to slightly shaly sand to clean sand reservoir. On the basis of petrophysics data, the reservoirs are interpreted a good quality reservoir rocks which has been confirmed with high effective porosity range between 20% and high hydrocarbon saturation exceeding 55% water saturation in well 1 and well 2. Water saturation 3 is nearly 100% although the reservoir properties are good

    1997-09-01

    Purpose: To assess serial CT as a measure of the progress of emphysema in patients with severe {alpha}{sub 1}-antitrypsin deficiency (phenotype PiZ). Material and Methods: In a randomized placebo-controlled study of {alpha}{sub 1}-antitrypsin augmentation therapy, 22 patients with moderate emphysema were followed for 2-4 years with an annual lung CT. The images were analysed by means of semiautomatic lung detection, and the degree of emphysema was quantitated by the density-mask and the percentile methods. The influence of lung volume was standardised by a regression model. Results: A highly significant decline in Hounsfield units (HU) was found in low-density areas, corresponding to a mean (SE) annual loss of lung tissue of 2.1 (0.4) g/l lung volume. Analysis of a single slice at 5 cm below the level of the carina gave comparable results: 2.4 (0.4) g/l. Conclusion: Serial CT is a sensitive measure of the progress of emphysema in patients with severe {alpha}{sub 1}-antitrypsin deficiency. (orig.).

    Immunization in India is marked with stark disparities across gender, caste, wealth and place of residence with severe shortfalls among those disadvantaged in more than one dimension. In this regard, an explicit recognition of intersectionality and intersectional inequalities has 2-fold relevance; one, being the pathway of health inequality and the other being its role as a deterrent of progress particularly at higher (better) levels of health. Against this backdrop, this study examines intersectional inequalities in immunization in India and also suggests a level-sensitive progress assessment method. The study uses group analogue of Gini coefficient for highlighting the magnitude of intersectional inequality and for comprehending its association with immunization level. The results unravel the plight of vulnerable intersectional groups and draw attention to disquieting shortfalls among female SCST (scheduled castes and tribes) children from rural areas. There is also some evidence to indicate leveraging among rural males in matters of immunization and it is further discerned that such gender advantage is greater among rural non-SCST community than the rural SCST group. In concluding, the study calls for intensive immunization planning to improve coverage among vulnerable communities in both rural and urban areas. PMID:24740707

    Full Text Available This article explores some of the key current research and statistical evidence available on the global scale of trafficking in human beings, and considers the assumption that the occurrence of trafficking is increasing. The value and limitations of this statistical data is identified, as is the relationship between the research base and the resulting legal and policy responses. This allows an assessment of whether there is a connection between the perceived problem and the responses to trafficking victims’ circumstances. It questions whether assumptions, generalisations and policies can be based around the available data and the responsibilities of individual countries, including the UK and the wider international community, in relation to the improvement of data collection. The article also considers signs of progress in terms of data collection and suggests further future improvements that need to be made to the approach taken.

    One of the major consequences of the reorganization of Nigeria from 4 states into 12 states in 1967 and then into 19 states in the late 1970s was the redistribution of the Nigerian population. Prior to 1967 Nigeria's rural population migrated primarily to the 4 state capitals of Kaduna, Ibadan, Enugu, Benin City and to the federal capital of Lagos. The creation of additional states, each with their own capital, provided new urban environments where migrants from rural areas were afforded opportunities for employment and social mobility. Between 1960-1980, World Bank estimates indicate that 1) population in Nigerian cityes of over 500,000 population increased from 22-57%; 2) the number of cities with a population of 500,000 or more increased from 2 to 9 and 3) the urban population increased from 13-20%. Given Nigeria's estimated population growth rate of 3.6%/year, it is imperative that the goverment continue its decentralization efforts. Tables show 1) population by region based on the 1963 census; 2) estimated population of the 19 state capitals for 1963 and 1975; and 3) estimated population of the areas included in each of the 19 states for 196o, 1977, 1979, and 19819 PMID:12266187

Secondary data 1980 to 2010 were used. Data were analysed using descriptive statistics, correlation analysis and regression analysis. Results show that total service trade value in Nigeria has increased from $1126.59 million in 1980 to $3076.19 million in 2010. Significant correlations existed between the total value of service trade and all the types of service trade except with other service trade value. Road network, government (domestic capital expenditure on services, agricultural credit and domestic service GDP positively determine exportable services. Recommendations include improvement of service GDP and agricultural credit/loan facilities.

  2. Assessing the effect of farmers' supplementation strategy on feed intake and live weight of goats grazing natural range and crop fields of Zamfara reserve in semi-arid Nigeria

    International Nuclear Information System (INIS)

    In the semi-arid Nigeria goats are raised extensively on natural grazing lands, crop residues, farm weeds and sometimes supplemented with industrial crop by-products. Under the extensive production system, supplementation has frequently been advocated as the main solution to the nutritional constraints livestock face during the long dry season (2 and 3). In order to design experiments to assess the optimum level of supplementation for the local producers, there is the need to assess their current practices. This experiment was therefore designed to test the farmers' feeding practices so as to ascertain its potential. This would serve as a baseline for designing future supplementation experiments with grazing animals. This on-farm study was conducted in Zamfara reserve northwestern Nigeria between July, 2002 and June, 2003 to assess feed intake and live weight of 12 indigenous Red Sokoto castrated bucks, separated into two groups of six, supplemented and unsupplemented respectively. The unsupplemented group grazed natural pasture and crop stubble of crop fields, whereas the supplemented group grazed natural pasture, crop stubbles and concentrate supplementation. Concentrate supplement (wheat offal) was fed at 1% of the metabolic weight of the animals, mean of the farmers offer. The total faecal collection method and grab samples of feed were used to estimate total intake of dry matter (DM), organic matter (OM), crude protein (CP) and metabolisable energy (ME) according to 3. Live weight of the animal was recorded at five weekly intervals. Results of the study indicated that nutrients intake of supplemented animals were generally higher than those of the unsupplemented group, but not significantly different (P > 0.05). However, supplementation significantly (P < 0.05) affected the live weight of the supplemented goats during early dry season in December. During this period feed became more available to the grazing animals from crop residues. It was therefore concluded that supplementation with wheat offal at 1% metabolic weight may not be enough to counteract weight loss of grazing goats during the other periods of the dry season in this environment)

    Allografts and other bone-grafts are frequently used for a variety of reconstructive approaches in orthopaedic surgery. However, successful allograft incorporation remains uncertain. Consequently, there is significant need for methods to monitor the fate of these constructs. Only few noninvasive methods can fully assess the progress of graft incorporation and to provide information on the metabolic status of the graft, such as the mineral and matrix composition of the regenerated-tissue that may provide early indications of graft success or failure. For example, Computed-tomography and MRI provide information on the morphology of the graft/host interface. Limited information is also available from DXA. To address this challenge, we present here the implementation of a noninvasive Raman spectroscopy technique for in-vivo assessment of allograft incorporation in animal-model. In an animal use committee approved osseointegration experiment, a 3mm defect is created in rat's tibia. The defect is reconstructed using auto or allograft and Raman spectra are collected at several time-points during healing using an array of optical-fibers in contact with the skin of the rat over the tibia while the rat is anaesthetized. The array allows excitation and collection of Raman spectra through the skin at various positions around the tibia. Raman parameters such as mineral/matrix, carbonate/phosphate and cross-linking are recovered and monitored. The system is calibrated against locally-constructed phantoms that mimic the morphology, optics and spectroscopy of the rat. This new technology provides a non-invasive method for in-vivo assessment of bone-graft incorporation in animal-models and can be adapted for similar study in human subjects.

  4. Recent progress in structural integrity assessment techniques for components subject to service-induced degradation

    International Nuclear Information System (INIS)

    Nuclear power plant components are exposed to a wide range of environmental and loading conditions which can cause degradation over time. Aging embrittlement, erosion-corrosion, irradiation embrittlement, stress corrosion cracking, and corrosion fatigue are examples of aging mechanisms which could reduce structural margins in reactor components. The degradation effects from these mechanisms have been seen more frequently with the aging of the early nuclear plants. Since there is a strong incentive for keeping these older plants running for longer periods of time without compromising safety, proper plant management to minimize damage from degradation mechanisms is extremely important. Structural margin assessment, monitoring, and maintenance are important elements of such a management plan. Significant progress has been recently made in the understanding, evaluation and monitoring of these degradation mechanisms. This has led also to new requirements in the ASME Code design basis for nuclear plants. Current state of understanding and new developments in the ASME Code to address some of these degradation mechanisms are covered in this paper. Cast stainless steels used in pump casings and valve bodies have been known to experience thermal aging embrittlement at reactor operating temperatures. Recent predictive models of thermal aging effects on material toughness, developed at Argonne National Lab are reviewed and applied to assess ASME Code structural margins of a reactor pump casing. A recent ASME Code Case provides methods for the evaluation and acceptance criteria for reactor pressure vessels having ductile fracture toughness values reduced below the requirements of 10CFR50 due to irradiation embrittlement. Background and application of this code case to an older BWR vessel is described. The occurrence of stress corrosion cracking in austenitic stainless steel piping highlighted the need for evaluation methods for structural margin assessment in piping

    Full Text Available he resultant of technological innovation has been the transformation in operational dimension of banks over some decades. Internet technology has brought about a paradigm shift in banking operations to the extent that banks embrace internet technology to enhance effective and extensive delivery of wide range of value added products and services. However, the fact that e-banking is fast gaining acceptance in Nigerian banking sector does not assuredly signify improved bank performance nor would conspicuous use of internet as a delivery channels make it economically viable, productive or profitable. Whether progression is made in the use of internet technology (e-banking or not, there should be parameter to empirically assess its impact over specified period of adoption. Consequently, the study examined the impact of electronic banking on banks’ performance in Nigeria. Panel data comprised annual audited financial statements of eight banks that have adopted e- and retained their brand name banking between 2000 and 2010 as well as macroeconomic control variables were employed to investigate the impact of e-banking on return on asset (ROA, return on equity (ROE and net interest margin (NIM. Result from pooled OLS estimations indicate that e-banking begins to contribute positively to bank performance in terms of ROA and NIM with a time lag of two years while a negative impact was observed in the first year of adoption. It was recommended that investment decision on electronic banking should be rational so as to justify cost and revenue implications on bank performance.

  6. Water quality issues in southern Nigeria

    International Nuclear Information System (INIS)

    There is a keen awareness of the effects of water quality on human health and behaviour in developing countries arising from well documented cases which can be found in the literature. Also in Nigeria there are various concerns about incidents of toxic waste disposal, groundwater pollution through oil spillages, waste disposal practices by agricultural, domestic and industrial activities which affect the domestic water supplies and the environment. The aims of this paper are to highlight the role of water quality in human health; provide a framework for water related health assessment, present results of case studies and recommend appropriate strategies to safeguard human health from contaminated water sources. Major health problems, other than those due to micro-biological contamination of water sources, such as cholera and typhoid, have not been reported or linked to water supplies in Nigeria. Yet there are symptoms of and growing incidences of various diseases, such as psychopathic and neurological disorders which have been linked to contaminated water supplies in developed countries. The major, minor and trace concentrations of elements in water supplies in Nigeria are usually determined in the ppm range whereas most trace elements are hazardous to human health in the ppb or ?g/l levels. The reason for this state of affairs is that the instrumentation required for determination of elemental concentrations at the ppb level is not readily available to researchers. Most reports on water quality do not provide any links to the major health problems which have been demonstrated elsewhere as responsible for major pathologic and neurologic disorders, including outright fatalities. Recent studies in Europe and Japan link several diseases, including kidney failure, mood disturbance and other neurologic disorders, heart, liver and kidney damage including death from eating poisonous fish caught in polluted waters, to contamination of water supplies by heavy metals in trace concentrations. Most of the ailments, including mood disturbances and psychological disorders, are reportedly on the increase in most urban and industrialized areas of Nigeria. Perhaps a study should be conducted among the population in order to relate the pattern of water pollution related diseases to health factors in Nigeria

    Science.gov (United States)

    Urama, J. O.

    Astronomy cannot be said to be entirely new in Nigeria. There are hundreds of cosmogony and ancient astronomical practices in Nigeria, but these need to be studied systematically. Nigerian ethnoastronomy is revealed in the folklore, ancient architecture, religious practices, traditional poetry and art works of the different ethnic groups. Though expressed within a cultural framework, much of Nigerian ethnoastronomy contains scientific principles of astronomy. This paper discusses the need to bridge the gap between ethnoastronomy in Nigeria and modern astronomy by providing scientific interpretation to such cosmogonies and ancient astronomical practices.

    1995-12-31

    The paper presents a condensed progress report on the performance assessment of Poland`s low-level waste disposal facility which is operating since 1961. The Rozan repository is of near-surface type with facilities which are the concrete fortifications built about 1910. Site characterization activities supplied information on regional geology, geohydrology, climatic and hydrologic conditions and terrain surface evolution due to geodynamic processes. Field surveys enabled to decode lithological, hydrogeological and geochemical site specific conditions. From the laboratory tests the data on groundwater chemistry and soil geochemical and hydraulic characteristics were obtained. The site geohydrologic main vulnerable element is the upmost directly endangered unconfined aquifer which is perched in relation to the region-wide hydraulic system. Heterogeneity of this system reflects in a wide range of hydraulic conductivity and thickness variations. It strongly affects velocity and flow directions. The chemistry of groundwater is unstable due to large sensitivity to external impacts. Modeling of the migration of the critical long-lived radionuclides Tc-99, U-238 and Pu-239 showed that the nearly 20 m thick unsaturated zone plays crucial role as an effective protective barrier. These radionuclides constitute minor part of the total inventory. Modeling of the development of the H-3 plume pointed out the role the macrodispersion plays in the unsaturated zone beneath the repository.

  12. Effective social justice advocacy: a theory-of-change framework for assessing progress.

    Science.gov (United States)

    Klugman, Barbara

    2011-11-01

    This article offers a theory-of-change framework for social justice advocacy. It describes broad outcome categories against which activists, donors and evaluators can assess progress (or lack thereof) in an ongoing manner: changes in organisational capacity, base of support, alliances, data and analysis from a social justice perspective, problem definition and potential policy options, visibility, public norms, and population level impacts. Using these for evaluation enables activists and donors to learn from and rethink their strategies as the political context and/or actors change over time. The paper presents a case study comparing factors that facilitated reproductive rights policy wins during the transition from apartheid to democracy in South Africa and factors that undermined their implementation in the post-apartheid period. It argues that after legal and policy victories had been won, failure to maintain strong organizations and continually rethink strategies contributed to the loss of government focus on and resources for implementation of new policies. By implication, evaluating effectiveness only by an actual policy change does not allow for ongoing learning to ensure appropriate strategies. It also fails to recognise that a policy win can be overturned and needs vigilant monitoring and advocacy for implementation. This means that funding and organising advocacy should seldom be undertaken as a short-term proposition. It also suggests that the building and maintenance of organisational and leadership capacity is as important as any other of the outcome categories in enabling success. PMID:22118149

    Full Text Available The study investigated the availability, utilization and management of ICT facilities in teaching English language in secondary schools in Kaduna State, Nigeria. The study adopted a descriptive survey research design. A questionnaire titled “Availability, Utilization and Management of Information and Communication Technology in teaching English Language in Secondary Schools” (AUMICTSS was used for data collection. Twenty randomly selected secondary schools from Kaduna metropolis were used for the study. A total of 100 teachers participated by responding to the items on the questionnaire. The data collected was analysed using frequencies and percentages. The findings of the study revealed that there is a dearth of ICT facilities in secondary schools in Kaduna as there are only very few of such facilities available in most of the schools visited. It also revealed that most teachers were not competent in the use of these facilities as the management of these facilities requires training and re-training. It was recommended as a matter of urgency that government should provide more ICT facilities in schools and ensure the provision of electricity in every secondary school for optimal utilization of these facilities. Teachers should equally be trained and re-trained regularly in the use and management of ICT facilities for effective English Language curriculum delivery.

  1. Assessment of occupational exposure to toxic metals in some paint and secondary iron and steel industries in Lagos, Nigeria using TXRF technique

    International Nuclear Information System (INIS)

    Full text: Lagos has remained one of the fastest growing cities especially in industrial infrastructure development. This has led to increased environmental problems. Yet there has been very little effort to monitor occupational exposure at various workplaces. Few selected paint industries and few secondary iron and steel industries in Lagos, Southwest Nigeria, were targeted for monitoring the heavy metal concentrations in their working environment. Ambient air at strategic locations within selected industries was sampled for twelve hour periods during the day time and the night time. Sampling was done using a stacked 'Gent' PM10 sampler and a twin-flow portable sampler, the latter for total suspended particulate matter. The filter holders were held at a height of 1.5 m above the ground. The filters were digested using ultra-pure acids and then analysed with a tube-excited Mo target x-ray source operating at 40 kV. Concentrations of toxic metal pollutants were measured using the total refection x-ray fluorescence technique. Quantification of concentrations of toxic metals was done using QXAS analysis package from IAEA. Ga was used as internal standard in the analysis. The elements of interest detected were Ca, Ti, V, Cr, Mn, Fe, Co, Zn and Pb. The ratios of the fine size fractions (dp p 3 to 36.2 ?g/m3 for the inhalable fraction. Toxicity potentials for the various elements were determined. (author)

  2. Assessment of occupational exposure to toxic metals in some paint and secondary iron and steel industries in Lagos, Nigeria using TXRF technique

    International Nuclear Information System (INIS)

    The concentration of PM2.5, PM10 and TSP in the work environments of a secondary iron and steel smelting and a paint industry in Lagos, Nigeria, were investigated using gravimetric sampling techniques and TXRF spectrometric analysis. The TXRF was used to analyse the concentration of toxic trace elements and heavy metals in the air-borne particulate. The elements detected included Ti, V, Cr, Mn, Fe, Co, Zn and Pb. Toxicity potentials of PM10 and PM2.5 suspended particulate matter and that of Pb were determined using USEPA national ambient air quality standards. Results were used to evaluate the possible occupational exposure for workers in the sampling areas, as well as those of the general public. These indicate that the concentrations of respirations dust and heavy metals in the work environments, especially the iron and steel smelter are high enough to affect the health of workers and the general public who reside in the neighbourhood. If combined with the effect of traffic pollution in this areas, the total air pollution load may be much higher than values recommended by WHO for general public protection. The need to investigate the options for emission reduction and the management of occupational and general public exposure was highlighted. (author)

  3. Radiological assessment of natural radionuclides in soil within and around crude oil flow and gas compression stations in the Niger Delta, Nigeria

    International Nuclear Information System (INIS)

    Natural radionuclide concentrations in soil samples collected within and around crude oil flow and gas compression stations in the Niger Delta, Nigeria, were determined using gamma-ray spectroscopy. The mean activity concentrations of 40K, 238U and 232Th varied from 30.1 ± 3.0 to 59.0 ± 17.1, B.D.L. to 8.8 ± 2.3 and 7.9 ± 3.7 to 10.9 ± 1.9 Bq.kg-1, respectively. The 40K, 238U and 232Th contents of the soil samples are very low compared with the world average for natural background area. The absorbed dose rate and effective dose ranged from 6.9 to 11.1 n Gy.h-1 and 8.5 to 13.6 ?Sv.y-1, respectively. The annual gonadal dose equivalent rate ranged from 48.9 to 77.5 ?Sv.y-1, which is lower than the world average of 0.30 mSv.y-1. The radium equivalent activity and the external hazard index of the soil samples were below the recommended limits of 370 Bq.kg-1 and unity, respectively. The results obtained reveal that there is no significant radiation hazard due to natural radionuclides of the soil samples in the studied areas. (authors)

  4. Nigeria’s Economic Growth: Emphasizing the Role of Foreign Direct Investment in Transfer of Technology

    2008-09-01

    Full Text Available The growth and development of Africa and indeed Nigeria’s economy depends largely on foreign direct investment (FDI, which has been described as the major carrier for transfer of new scientific knowledge and related technological innovations. The need to step up Nigeria’s industrialization process and growth, calls for more technology spill-over through foreign investment. This article examines Nigeria’s Economic situation, explores the link between FDI and technology transfer to foreign subsidiaries and spillover to Nigeria’s domestic firms. In doing so it offers sustained analysis of available literature, policy documents, official reports and economic information on Nigeria. The article concludes that FDI can facilitate economic growth in Nigeria by generating both technological and efficiency spillovers to local firms, encouraging innovation, allowing technology adoption and developing human capital.

  5. Non-invasive diagnostic methods for atherosclerosis and use in assessing progression and regression in hypercholesterolemia

    International Nuclear Information System (INIS)

    We evaluated the wall thickening and stenosis rate (ASI), the calcification rate (ACI), and the wall thickening and calcification stenosis rate (SCI) of the lower abdominal aorta calculated by the 12 sector method from simple or enhanced computed tomography. The intra-observer variation of the calculation of ASI was 5.7% and that of ACI was 2.4%. In 9 patients who underwent an autopsy examination, ACI was significantly correlated with the rate of the calcification dimension to the whole objective area of the abdominal aorta (r=0.856, p<0.01). However, there were no correlations between ASI and the surface involvement or the atherosclerotic index obtained by the point-counting method of the autopsy materials. In the analysis of 40 patients with atherosclerotic vascular diseases, ASI and ACI were also highly correlated with the percentage volume of the arterial wall in relation to the whole volume of the observed artery (r=0.852, p<0.0001) and also the percentage calcification volume (r=0.913, p<0.0001) calculated by the computed method, respectively. The percentage of atherosclerotic vascular diseases increased in the group of both high ASI (over 10%) and high ACI (over 20%). We used SCI as a reliable index when the progression and regression of atherosclerosis was considered. Among patients of hypercholesterolemia consisting of 15 with familial hypercholesterolemia (FH) and 6 non-FH patients, the change of SCI (d-SCI) was significantly correlated with the change of total cholesterol concentration (d-TC) after the treatment (r=0.466, p<0.05) and the change of the right Achilles' tendon thickening (d-ATT) was also correlated with d-TC (r=0.634, p<0.005). However, no correlation between d-SCI and d-ATT was observed. In conclusion, CT indices of atherosclerosis were useful as a noninvasive quantitative diagnostic method and we were able to use them to assess the progression and regression of atherosclerosis.

  9. Improving energy efficiency in Nigeria

    International Nuclear Information System (INIS)

    Despite its huge population of about 100 million people, Nigeria consumes a relatively small share of the world's energy. GDP per capita equaled about US$ 800 in 1985. Agriculture accounts for the largest portion of GDP, at around 40%, followed by services with 31%, industry with 25% and transport with 4$. Unlike most other African nations, Nigeria has abundant energy sources. Recent estimates assumed that Nigeria has about 16 billion barrels of oil, 30 billion barrels of oil equivalent (boe) of gas and 3 billion boe of coal. The results of two long-term energy use and carbon emissions scenarios for Nigeria indicate that between 1985 and 2025, Nigeria's energy consumption will rise substantially as both population and economic growth rates soar. While biomass consumption drops markedly over the observed time period, gas and oil consumption witness significant increases. Coal and solar power also account for increasing shares of Nigeria's energy supply in the coming four decades. Hydro's share in energy use remains stable

  13. Beyond the Rhetorics of Statecraft in Africa: Searching for a New Paradigm of Leadership in Nigeria

    Directory of Open Access Journals (Sweden)

    J. David Agaba

    2010-01-01

    Full Text Available Leadership question features most prominently in virtually all reported analyses, comments and interviews in the media, especially the print media. One thing that is evident is the recognition of leadership deficit as an important factor in understanding Africa and indeed Nigeria’s predicament. Chinua Achebe, in “The Trouble with Nigeria” identified leadership failure as the bane of development in Nigeria and by implication in most of Africa. As a matter of fact, even honest African leaders like the late Nnamdi Azikiwe (Nigeria, late Kwame Nkrumah (Ghana, and Nelson Mandela (South Africa had in the past pointed at the leadership malaise in development in the continent. This paper therefore examines leadership and governance in Nigeria within the framework of servant- leadership. We noted that for Nigeria to evolve a positive and focus leadership with morals, values and accountability, there is the need for selfless in the form of putting others above self in service delivery, which is the essence of servant-leadership. The creating of a culture of servant leader-leadership in Nigeria would mean the replacement of the top-bottom culture with one where attributes of servant-leadership as already identified flourish. It would require having in place a leadership that has “worked well enough to be considered valid.” It is, therefore, an evidence of internalization of values and “a stabilizing force which creates social reality for its techniques for creating a culture of servant-leadership which is not possible except there is progress in evolving a team of servant-leaders.

    Abstract Background Breast cancer is the commonest cancer among women in Nigeria and globally. In Nigeria, late presentations of breast cancer cases have also been consistent for three decades. In an environment where there is no established national screening program for breast cancer, it is pertinent to assess the knowledge of breast cancer and its early detection measures. The objective of this study therefore, was to assess rural women's level of knowledge of breast cancer and its early d...

  15. Nigeria's energy policy: Inferences, analysis and legal ethics toward RE development

    International Nuclear Information System (INIS)

    The study critically assessed the various policy issues of sustainable energy development in Nigeria. The basic focus was to discuss and analyze some of the laws of the federation as it relates to the development of Renewable Energy in Nigeria. It surveyed the nation's energy policy statement and the vision 20:2020 of the federal government. The Renewable Energy Master Plan developed by the joint efforts of the Energy Commission of Nigeria and United Nations Development Programs were also appraised. The level of development and the index of renewable energy production as stated by the policy statement, the vision 20:2020 and the Renewable Energy Master Plan were highlighted. The study found some policy challenges which include weak government motivation, lack of economic incentives, multiple taxations, non-existent favorable customs and excise duty act to promote renewable energy technologies. Further to this, some legal reforms which may aid the promotion of renewable energy development in Nigeria and also make robust the nation's energy policy were proposed. Some of the laws that require amendment to promote renewable energy include the land use act, environmental impact assessment decree and the investment laws of the federation of Nigeria. - Highlights: • The study exposed the energy policy issues of Nigeria. • The various policy documents and the energy statement of vision 20:2020 were surveyed. • Various challenges impinging growth or renewable energy were highlighted. • Some suggestions for policy reformation were proposed

    2015-03-01

    Full Text Available The success of performance of public sector projects in Nigeria is tied to the impact of procurement strategy or policy used in providing the building. Procurement policies significantly influence the success of construction projects since they are designed to provide solutions to specific project needs or conditions. The Nigerian construction industry was analyzed with particular emphasis on public sector procurement. The general performance of public sector projects in Nigeria was broadly assessed and quite unfortunately the literature review has criticized public sector procurement in Nigeria of been inefficient for efficient project delivery. Equally the respondents to the survey data obtained from the questionnaire distributed and oral interview conducted suggest that projects are affected by the procurement strategy adopted for project delivery. A significant number of the questionnaire respondents believe that performance of projects could be improved using alternative or hybrid procurement strategies. Recommendations were proffered in order to mitigate or reduce completely the challenges and complexities faced by public project procurement schemes in Nigeria.

  18. Solar Cell Production in Nigeria: Prospects, Options and Problems

    International Nuclear Information System (INIS)

    The prospects and problems facing solar cell production in Nigeria are discussed. The paper reviews many proven solar cell materials in terms of their current efficiencies and production costs. Silicon solar cell production appears to be the best technology option for Nigeria because of the abundant quartz sand and waste products from our phosphate fertiliser company that can be employed as starting materials to produce solar grade silicon. Factors affecting solar cell efficiency, choice of solar cell as well as financial and material problems limiting the progress on silicon solar cell production are also discussed. Finally, the paper recommends the simultaneous production of solar grade silicon and coordinated development of the balance of system components as first steps towards actualizing this objective

    The analysis of naturally occurring radionuclides ((226)Ra, (232)Th and (40)K) has been carried out in soil samples collected from oil and gas field environment of Delta state, using gamma spectroscopy operated on a Canberra vertical high purity 2?×2? NaI(TI) detector. The activity concentration of the samples ranges from 19.2 ± 5.6Bqkg(-1) to 94.2 ± 7.7Bqkg(-1) with mean value of 41.0 ± 5.0Bqkg(-1) for (226)Ra, 17.1 ± 3.0Bqkg(-1) to 47.5 ± 5.3Bqkg(-1) with mean value of 29.7 ± 4Bqkg(-1) for (232)Th and 107.0 ± 10.2Bqkg(-1) to 712.4 ± 38.9Bqkg(-1) with a mean value of 412.5 ± 20.0Bqkg(-1) for (40)K. These values obtained are well within the world range and values reported elsewhere in other countries, but are little above some countries reported average values and some part of Nigeria. The study also examined some radiation hazard indices, the mean values obtained are, 98.5 ± 12.3Bq.kg(-1), 0.8Bqkg(-1), 54.6?Gyh(-1), 0.07?Svy(-1), 0.3 and 0.4 for Radium equivalent activity (Ra(eq)), Representative level index (I?), Absorbed Dose rates (D), Annual Effective Dose Rates (E(ff) Dose), External Hazard Index (H(ex)) and Internal Hazard Index (H(in)) respectively. These calculated hazard indices to estimate the potential radiological health risk in soil and the dose rate associated with it are well below their permissible limit. The soil and sediments from the study area provide no excessive exposures for inhabitants and can be use as construction materials without posing any immediate radiological threat to the public. However, oil workers in the fields and host communities are cautioned against excess exposure to avoid future accumulative dose of these radiations from sludge and sediment of this area.

    Full Text Available Abstract Background The Cross River region in Nigeria is an extremely diverse area linguistically with over 60 distinct languages still spoken today. It is also a region of great historical importance, being a adjacent to the likely homeland from which Bantu-speaking people migrated across most of sub-Saharan Africa 3000-5000 years ago and b the location of Calabar, one of the largest centres during the Atlantic slave trade. Over 1000 DNA samples from 24 clans representing speakers of the six most prominent languages in the region were collected and typed for Y-chromosome (SNPs and microsatellites and mtDNA markers (Hypervariable Segment 1 in order to examine whether there has been substantial gene flow between groups speaking different languages in the region. In addition the Cross River region was analysed in the context of a larger geographical scale by comparison to bordering Igbo speaking groups as well as neighbouring Cameroon populations and more distant Ghanaian communities. Results The Cross River region was shown to be extremely homogenous for both Y-chromosome and mtDNA markers with language spoken having no noticeable effect on the genetic structure of the region, consistent with estimates of inter-language gene flow of 10% per generation based on sociological data. However the groups in the region could clearly be differentiated from others in Cameroon and Ghana (and to a lesser extent Igbo populations. Significant correlations between genetic distance and both geographic and linguistic distance were observed at this larger scale. Conclusions Previous studies have found significant correlations between genetic variation and language in Africa over large geographic distances, often across language families. However the broad sampling strategies of these datasets have limited their utility for understanding the relationship within language families. This is the first study to show that at very fine geographic/linguistic scales language differences can be maintained in the presence of substantial gene flow over an extended period of time and demonstrates the value of dense sampling strategies and having DNA of known and detailed provenance, a practice that is generally rare when investigating sub-Saharan African demographic processes using genetic data.

    2009-08-01

    Activity concentrations of the selected radionuclides (40)K, (226)Ra and (232)Th were measured in surface soil samples collected from 38 cities in the southwest region of Nigeria by means of gamma spectroscopy with a high-purity germanium detector. Measured activity concentration values of (40)K varied from 34.9 +/- 4.4 to 1,358.6 +/- 28.5 Bq kg(-1) (given on a dry mass (DM) basis) with a mean value of 286.5 +/- 308.5 Bq kg(-1); that of (226)Ra varied from 9.3 +/- 3.7 to 198.1 +/- 13.8 Bq kg(-1) with a mean value of 54.5 Bq kg(-1) and a standard deviation of 38.7 Bq kg(-1), while that of (232)Th varied from 5.4 +/- 1.1 to 502.0 +/- 16.5 Bq kg(-1) with a mean value of 91.1 Bq kg(-1) and standard deviation of 100.9 Bq kg(-1). The mean activity concentration values obtained for (226)Ra and (232)Th are greater than the world average values reported by the United Nations Scientific Committee on Effects of Atomic Radiation for areas of normal background radiation. Radiological indices were estimated for the radiation/health hazards of the natural radioactivity of all soil samples. Estimated absorbed dose rates in air varied from 12.42 +/- 2.25 to 451.33 +/- 19.06 nGy h(-1), annual outdoor effective dose rates from 0.015 +/- 0.003 to 0.554 +/- 0.023 mSv year(-1), internal hazard index from 0.10 +/- 0.03 to 3.02 +/- 0.16, external hazard index from 0.07 +/- 0.01 to 2.60 +/- 0.11, representative level index from 0.19 +/- 0.03 to 6.84 +/- 0.29, activity index from 0.09 +/- 0.02 to 3.42 +/- 0.15, and radium equivalent activity from 26.95 +/- 5.04 to 963.15 +/- 41.87 Bq kg(-1). Only the mean value of the representative level index exceeds the limit for areas of normal background radiation. All other indices show mean values that are lower than the recommended limits.

    Full Text Available Abstract Background Exclusive breast feeding (EBF has important protective effects on the survival of infants and decreases risk for many early-life diseases. The purpose of this study was to assess the factors associated with EBF in Nigeria. Methods Data on 658 children less than 6 months of age were obtained from the Nigeria Demographic and Health Survey (NDHS 2003. The 2003 NDHS was a multi-stage cluster sample survey of 7864 households. EBF rates were examined against a set of individual, household and community level variables using a backward stepwise multilevel logistic regression method. Results The average EBF rate among infants younger than 6 months of age was 16.4% (95%CI: 12.6%-21.1% but was only 7.1% in infants in their fifth month of age. After adjusting for potential confounders, multivariate analyses revealed that the odds of EBF were higher in rich (Adjusted Odds Ratios (AOR = 1.15, CI = 0.28-6.69 and middle level (AOR = 2.45, CI = 1.06-5.68 households than poor households. Increasing infant age was associated with significantly less EBF (AOR = 0.65, 95%CI: 0.51-0.82. Mothers who had four or more antenatal visits were significantly more likely to engage in EBF (AOR = 2.70, 95%CI = 1.04-7.01. Female infants were more likely to be exclusively breastfed than male infants (AOR = 2.13, 95%CI = 1.03-4.39. Mothers who lived in the North Central geopolitical region were significantly more likely to exclusively breastfeed their babies than those mothers who lived in other geopolitical regions. Conclusions The EBF rate in Nigeria is low and falls well short of the expected levels needed to achieve a substantial reduction in child mortality. Antenatal care was strongly associated with an increased rate of EBF. Appropriate infant feeding practises are needed if Nigeria is to reach the child survival Millennium Development Goal of reducing infant mortality from about 100 deaths per 1000 live births to a target of 35 deaths per 1000 live births by the year 2015.

Traditional tools are expensive, time consuming, complex, and based on topics that clinicians or researchers think are important. Thus, they typically do not provide patient-centered information that is meaningful and relevant to the lives of patients with substance use disorders. To improve our ability to understand patients’ progress in treatment from their perspectives, the authors and colleagues developed a patient-oriented assessment instrument that has considerable advantages over existing instruments: brevity, simplicity, ease of administration, orientation to the patient, and cost (none. The resulting Treatment Effectiveness Assessment (TEA elicits patient responses that help the patient and the clinician quickly gauge patient progress in treatment and in recovery, according to the patients’ sense of what is important within four domains established by prior research. Patients provide both numerical responses and representative details on their substance use, health, lifestyle, and community. No software is required for data entry or scoring, and no formal training is required to administer the TEA. This article describes the development of the TEA and the initial phases of its application in clinical practice and in research.Keywords: substance use disorders, global treatment progress, brief instrument, patient-centered

  6. Assessing the progress of rehabilitation in patients with ACL reconstruction using the International Knee Documentation Committee Subjective Knee Form

    International Nuclear Information System (INIS)

    There are numerous assessment tools designed to provide information on the results of reconstructive surgery of anterior cruciate ligament (ACL). They are also used for monitoring progress and facilitating clinical decision-making during the rehabilitation process. A brief summary of some existing tools specifically designed to evaluate knee ligament injuries is presented in this article. Then, one of those outcome measures, the International Knee Documentation Committee Subjective Knee Form (IKDC) was applied to a group of patients (N = 10) who had undergone surgery for ACL reconstruction. The patients attended the same physiotherapy service and followed a unified rehabilitation protocol. The assessment was performed twice: four and six months after surgery. The results showed an improvement in the rehabilitation of most patients tested (verified by a difference equal to or greater than 9 points on the IKDC outcome between measurements 1 and 2). The IKDC probed to be an instrument of quick and easy application. It provided quantitative data about the progress of rehabilitation and could be applied in everyday clinical physiotherapy practice. However, the results suggested considering the IKDC as one component of an evaluation kit to make decisions regarding the progress of the rehabilitation treatment.

    Full Text Available Boat mishaps tend to be increasing in Nigeria in spite of all regulatory measures which have been taken to prevent and control marine accidents. Boat mishaps could occur anywhere water transportation takes place. However, there is a general impression that water transportation takes place only in the riverine areas located in Southern Nigeria but, this paper reports about marine accident cases in Northern Nigeria. It evaluates the safety measures put in place by operators and other institutional bodies in the areas and assesses the level of infrastructure in terms of quantity, quality and accessibility to boat operators, boat users and institutional staff. Questionnaires were administered through individual and group interviews with boat owners, boat drivers, boat users, boat builders, boat engine mechanics, local government officials, maritime workers union, the marine police, traditional regulators and staff of the federal government agencies for maritime affairs. The paper found that marine transportation is neglected in Northern Nigeria with dilapidated jetties, ill-equipped marine police, non-functional ferries and boast meant to be used by federal officials and wrecks in water channels without removal. Maritime safety is therefore compromised with cases of overloading carrying people, animals, grains and petroleum products in one boat without fire extinguisher and no lifejackets. The paper concludes that there are considerable water transportation activities in Northern Nigeria without a corresponding government attention. It is therefore recommend that government should intervene by providing lifejackets, fire extinguishers, training of surveyors, refurbishing ferries for enforcement as well as creating safety awareness in the region.

    This study describes the spatial and temporal variations in the physiologic climate of Nigeria for 1951-2009 in terms of effective temperature (ET), temperature-humidity index (THI), relative strain index (RSI) and perception of 3,600 sampled populations. The main hypotheses are that (i) the existing vegetation-based ecological region could adequately elucidate the physiologic climate of the country, and (ii) physiologic stress has significantly increased over the years (1951-2009). Trends and changes in the selected indices (ET, THI and RSI) were examined over two time slices: 1951-1980 and 1981-2009. The results show that (1) the montane region was the most comfortable physiologic climate in Nigeria, and the regions around the Rivers Niger and Benue troughs were the most uncomfortable in most parts of the year, (2) physiologic stress in most parts of Nigeria has significantly increased in 1981-2009 over 1951-1980 ( p ? 0.05), (3) coping strategies to the uncomfortably hot and cold climate in Nigeria are limited to dressing mode, clothing materials and use of air conditioners or fan, (4) ET, THI and RSI results could be similar, and complementary; but each is with its strengths and weaknesses for annual or seasonal representations, which the others complemented for the interpretation of the physiologic climate of Nigeria. The study concluded that the relationship between the ecological classification of Nigeria and physiologic climate is rather complex, and the former could not elucidate the latter. The study cited inadequate meteorological data, especially on wind chill, and health records as limiting factors of studies on the Nigerian physiologic climates and the effect of extreme thermal conditions on the people.

    Full Text Available Through accident or act of terrorism, structures may be subject to conditions that could lead to progressive collapse. A large part of common reinforced concrete (RC structures are designed as intermediate moment resisting frames. In this study, based on the acceptance criteria of the last edition of UFC 4-023-03 document, the influence of some external column removal cases are evaluated by nonlinear procedures in all stories of a regular structure. Nonlinear static and nonlinear dynamic analyses are conducted to estimate the progressive collapse resistance of the building subjected to column failure. Results show that after column removal in top stories, in both nonlinear static and dynamic analysis, the structure hinges exceeds CP level of performance. Compared to dynamic analyses, it is concluded that static analyses are more conservative in the estimation of total number of plastic hinges and shear force in beams.

  11. Threat to Nigeria Since 1960: A Retrospection

    Directory of Open Access Journals (Sweden)

    L. Andy Afinotan

    2014-06-01

    Full Text Available The post-independence Nigerian state was faced with the intractable task of governing a multifaceted nation, comprised of 36 regional states which were divided along ethno-religious lines, up to 300 ethnic groups and a plethora of linguistic dialects, in addition to three (3 distinct religious groupings. The challenge of the post-colonial Nigerian state was the efficient administration and governance of a broad-based society with a multiplicity of interests, values, traditions and cultural inclinations. The culmination of an atmosphere of mutual mistrust and dissatisfaction from different regions of Nigeria came with the advent of the Biafra secessionist battle of 1967. Following the end of the Biafra conflict, the Nigerian society became characterised with struggles and resistance against the state system in various forms, with the gripes and disquiets of various groups coming to the fore in various, often violent ways. Making use of library research and content analysis methologies, the authors trace the sequence of crises faced by the Nigerian state since independence, with a keen focus on the Biafra War of 1967, the Niger Delta crisis (particularly, the botched Amnesty Programme of 2009, as well as the current threat of Boko Haram terrorism which has taken hold of the Nigerian society since 2009. The paper concluded that, for the high ideals of Unity and Faith, Peace and Progress to be attained in Nigeria, the State must deal with corruption, ethnicity, religious fundamentalism and security related crimes, while doing more to restructure the polity and enthrone free and fair elections.

  15. Teaching Inquiry in Nigeria and Canada

    Science.gov (United States)

    Strubbe, Linda

    2015-08-01

    Inquiry is a teaching strategy in which student work mirrors authentic scientific research: students have ownership over their learning path, and learning scientific concepts (e.g., properties of light, motion in a gravitational field) is intertwined with learning scientific practices (e.g., asking questions, planning an investigation, constructing explanations). I will describe inquiry and education research showing its effectiveness; and I will present inquiry-based astronomy curricula and assessment strategies we have designed for undergraduate and graduate courses in Nigeria and Canada: an activity on the cosmic distance ladder (part of a short course in Abuja); a course on order-of-magnitude astronomy problem solving (Toronto); and new education research from the Carl Wieman Science Education Initiative at the University of British Columbia (where I am a new postdoc).

    Lamidi W.A

    2013-06-01

    Full Text Available Different methods of assessment on the students learning outcomes in Agricultural Science at five different secondary schools in Ila-Orangun, Osun State were studied. An arm of a class was used for each test; Continuous Assessment (CA and Conventional Method (CM were used for each arm. Students were taught during their normal school times for the maximum time of forty minutes thrice a week. There were ten objective questions weekly for each assessment of the students in the CA method for six weeks. The same questions were used throughout for all the schools, done simultaneously for CA. Also, sixty questions at once at the end of the sixth week for CM. Standard deviation and regression equations for the mean values were used in the analysis. The results show that CA could be adjudged to be better off than the CM because of its higher mean values in all the schools than the CM. The higher R2 values of 0.99 and 0.88 revealed stronger correlation between different methods of assessment and the targeted learners. The CA test should be used instead of CM; the CM does not make learners to gain much cognitive knowledge when compare with what CA does to students.

  17. Assessment the Behavior of Seismic Designed Steel Moment Frames Subjected to Progressive Collapse

    Directory of Open Access Journals (Sweden)

    Azlan Bin Adnan

    2014-02-01

    Full Text Available Recent investigations reveal that progressive collapse phenomenon is dominant behavior in the majority of steel structures. Although the design of buildings is based on the fact that they need to withstand all the loads exerted on the structure, failure occurs as a result of inadequate design and modeling techniques, particularly for abnormal and extreme loading conditions. Once one or more load bearing member is eliminated from the structure, progressive collapse, mainly in columns, will commence. By the time a column is eliminated from the structure as a result of a sudden motor vehicle strike or earthquake or fire or any other internal or external factor that could take one column out of the system, the weight of the building (gravity load will be distributed among other columns within the structure. Failure commences in the part of the structure that has lost a column unless other columns are designed appropriately against gravity loads and are capable of redistribution of additional loads imposed on them. Failure of vertical load bearing elements will continue until the stabilization of extra loading. Hence, this could lead to serious damage and collapse of the building which will lead to higher damage to the building than the primary damage. This research is based on the regulations conforming to the specifications of UFC guidelines and the structures have been modeled using SAP2000 (2012. In order to study the effects of the progressive collapse on the seismic design of special steel moment frames, SMRF, two 5-story and 15-storystructures are modeled in SAP2000 (2012. In order to have a better understanding of progressive collapse and obtain reliable results, Linear Static (LS, Nonlinear Static (NLS and Nonlinear Dynamic analyses (NLD procedure for single and 2 adjacent columns removal have been implemented in this study. Having a good perception of the possibility of progressive collapse involves incorporation of demand capacity ratio, plastic hinges formation and vertical displacements of removed column’s location plus axial force in columns adjacent to the removed column. Other factors such as number of stories and the amount of local damage resulted from the removal of 2 adjacent columns could also lead to a better understanding of the structural behavior.

  18. Uranium favourability study in Nigeria

    Science.gov (United States)

    Oshin, I. O.; Rahaman, M. A.

    Geological considerations indicate that four types of uranium deposits, three from within the crystalline rocks and the fourth from the sedimentary formations, can be explored for in Nigeria. The Precambrian Basement Complex underwent crustal reactivation in Pan-African times (600 ± 150 Ma) during which migmatites and rocks of the Older Granite suite were emplaced. The occurrences of these rocks in northeastern, north-central and central Nigeria are possible hosts for the granitic type of uranium deposit. Vein-type uranium deposits are often localized in areas of the Basement Complex which have undergone intense brittle deformation. The high-level, anorogenic, peralkaline Younger Granites of Nigeria of Carboniferous to Cretaceous age have geochemical characteristics which are similar to those of the host rocks of non-orogenic type uranium deposit in alkali complexes such as the Bokan mountains of Alaska. The sandstone type of uranium deposit may be found in the Cretaceous-Recent continental sandstone formations in the Sokoto, Niger, Chad and Benue Basins of Nigeria and in the sediments overlying the Oban Massif in Cross Rivers State. Geologically similar sandstone occurrences elsewhere in the world (Gabon, Niger and Colorado, U.S.A.) are known to harbour important uranium mineralization.

    1993-01-01

    The Nigeria chapter of the African Network for the Prevention and Protection Against Child Abuse and Neglect conducted a nationwide study to acquire an overview of the nature and extent of child abuse and neglect in Nigeria. The 3-part study assessed the density of children working on the streets and the attitudes of adults and children related to child abuse and neglect. Counts of working street youths under age 16 years and respondent attitudes were assessed in Kaduna/Zaria, Enugu/Onitsha, and Ibadan. The densities of street children and questionnaire responses from sampled adults suggest that child abuse and neglect are serious problems in Nigeria; cultural practices and traditional attitudes contribute to the problem; institutions tasked with addressing family and child welfare have failed to do so; hawking, begging, and abandonment place these children at risk; and some handicapped children roam the streets without care. School children were surveyed to provide information on their before- and after-school chores, their views on physical punishment by parents and teachers, and their nutritional standards. 94% received three meals/day; 52% typically spent 2-4 hours after school in domestic chores such as sweeping the house, washing dishes, and preparing evening meals; and many were either scolded, beaten, or assigned additional household duties as punishment for behaving contrary to the desires of adults.

    Full Text Available We examine the TQM Strategies and health care delivery in Nigeria, and the various means of measuring service quality. Nigeria continues to suffer outbreaks of various diseases cholera, malaria, cerebrospinal meningitis, measles, yellow fever, Bird flu e.t.c., all these diseases combine to cause high morbidity and mortality in the population. To assess the situation this paper looks at the relevant indicators like Annual Budgets by Government, Individual’s income, the role of Nigerian Medical Association (NMA and various health care agencies vested with the sole responsibility for elaborating standards for products and processes in Health care Delivery.The paper also examines the implication of Government Budget estimates on the Life expectancy of an average Nigerian. The findings necessitated the need for the government to seek support from WHO to assist in strengthening the health care system by advocating and providing technical support to health sector reforms.

  4. A critical review of reductionist approaches for assessing the progress towards sustainability

    International Nuclear Information System (INIS)

    The increasing prominence of Sustainable Development as a policy objective has initiated a debate on appropriate frameworks and tools that will both provide guidance for a shift towards sustainability as well as a measure, preferably quantitative, of that shift. Sustainability assessment has thus the challenging task of capturing, addressing and suggesting solutions for a diverse set of issues that affect stakeholders with different values and span over different spatial and temporal scales. However sustainability assessment is still not a mature framework in the sense that Environmental Impact Assessment (EIA) and Strategic Environmental Assessment (SEA) are. This paper aims to provide suggestions for improving the sustainability evaluation part of a sustainability assessment. In particular it will provide a comprehensive review of different sustainability evaluation tools (from a reductionist perspective) as well as the feasibility of incorporating them within a sustainability assessment framework. Reviewed tools include monetary tools, biophysical models and sustainability indicators/composite indices that have been developed within different disciplines such as economics, statistics, ecology, engineering and town planning

    2013-01-01

    A national healthcare company applied the Malcolm Baldrige Criteria for Performance Excellence and its "Are We Making Progress?" survey as an annual organizational self-assessment to identify areas for improvement. For 6 years, Liberty Healthcare Corporation reviewed the survey results on an annual basis to analyze positive and negative trends, monitor company progress toward targeted goals and develop new initiatives to address emerging areas for improvement. As such, the survey provided a simple and inexpensive methodology to gain useful information from employees at all levels and from multiple service sites and business sectors. In particular, it provided a valuable framework for assessing and improving the employees' commitment to the company's mission and values, high standards and ethics, quality of work, and customer satisfaction. The methodology also helped the company to incorporate the philosophy and principles of continuous quality improvement in a unified fashion. Corporate and local leadership used the same measure to evaluate the performance of individual programs relative to each other, to the company as a whole, and to the "best practices" standard of highly successful companies that received the Malcolm Baldrige National Quality Award.

  7. Shuttle Risk Progression: Use of the Shuttle Probabilistic Risk Assessment (PRA) to Show Reliability Growth

    Hamlin, Teri L.

    2011-01-01

    It is important to the Space Shuttle Program (SSP), as well as future manned spaceflight programs, to understand the early mission risk and progression of risk as the program gains insights into the integrated vehicle through flight. The risk progression is important to the SSP as part of the documentation of lessons learned. The risk progression is important to future programs to understand reliability growth and the first flight risk. This analysis uses the knowledge gained from 30 years of operational flights and the current Shuttle PRA to calculate the risk of Loss of Crew and Vehicle (LOCV) at significant milestones beginning with the first flight. Key flights were evaluated based upon historical events and significant re-designs. The results indicated that the Shuttle risk tends to follow a step function as opposed to following a traditional reliability growth pattern where risk exponentially improves with each flight. In addition, it shows that risk can increase due to trading safety margin for increased performance or due to external events. Due to the risk drivers not being addressed, the risk did not improve appreciably during the first 25 flights. It was only after significant events occurred such as Challenger and Columbia, where the risk drivers were apparent, that risk was significantly improved. In addition, this paper will show that the SSP has reduced the risk of LOCV by almost an order of magnitude. It is easy to look back afte r 30 years and point to risks that are now obvious, however; the key is to use this knowledge to benefit other programs which are in their infancy stages. One lesson learned from the SSP is understanding risk drivers are essential in order to considerably reduce risk. This will enable the new program to focus time and resources on identifying and reducing the significant risks. A comprehensive PRA, similar to that of the Shuttle PRA, is an effective tool quantifying risk drivers if support from all of the stakeholders is given.

  8. An assessment of recent Iranian fertility trends using parity progression ratios

    Directory of Open Access Journals (Sweden)

    Peter McDonald

    2015-06-01

    Full Text Available Background: In 2013 a draft population bill was introduced in the Iranian Parliament. Based on the presumption that fertility in Iran had fallen to a very low level, the bill proposed a wide range of pronatalist policies with the aim of increasing fertility to 2.5 births per woman. The draft law called for restrictions on the employment of women and young single people and inducements for women to marry in their late teens. New estimates of fertility, such as those provided in this paper, cast doubt upon the view that fertility had fallen to a very low level. In May 2014 a statement issued by the Supreme Leader provided guidelines for a more moderate approach to sustaining fertility at around the replacement level. Objective: To measure the trend in fertility in Iran, especially from 2000 onwards. Methods: Using the 2010 IDHS, the synthetic cohort parity progression ratio method is used to measure the fertility trend in Iran. Synthetic parity progressions are compared with real cohort parity progressions to examine the presence of tempo effects. Comparison is made with age-based measures from surveys, censuses, and the birth registration system. Results: This paper demonstrates that fertility in Iran was constant for the decade 2000-2009, at a level of around 1.8-2.0 births per woman. Conclusions: Our findings provide evidence supporting a more moderate approach to sustaining fertility in Iran at around the replacement level. Comments: The paper demonstrates the advantages of parity-based measurement over age-based measurement when tempo effects may be involved.

  11. State financed PV technology projects in Nigeria

    International Nuclear Information System (INIS)

    Despite the progress made by the democratic government of Nigeria to eradicate poverty, there are still millions of people without access to electricity. It would not be financially viable to extend the national electricity grid to each electoral ward, in remote locations in the country. The use of photovoltaic technology now brings electricity to many rural areas as part of the provision of basic needs by the Nigerian authorities. The Nasarawa State Government has embarked on the provision of all it electoral wards with solar powered water supply systems to carter for a mostly rural population of 3.4 million people. The Benue, Taraba, Bauchi and Jigawa State governments have embarked on similar schemes in Rural Water Supply, Health and the Educational sectors of the economy. Ambitious PV programmes, of this nature, inevitably face challenges in developing countries. The preliminary recommendations, of this ongoing study, have been made to address some of the potential challenges in some of the key areas. This paper reviews the implementation progress and suggests some of the lessons that might be learnt. (authors)

  12. A CAD system for assessment of MRI findings to track the progression of multiple sclerosis

    Wong, Alexis; Gertych, Arkadiusz; Zee, Chi-Shing; Guo, Bing; Liu, Brent J.

    2007-03-01

    Multiple sclerosis (MS) is a progressive neurological disease affecting myelin pathways. MRI has become the medical imaging study of choice both for the diagnosis and for the follow-up and monitoring of multiple sclerosis. The progression of the disease is variable, and requires routine follow-up to document disease exacerbation, improvement, or stability of the characteristic MS lesions or plaques. The difficulties with using MRI as a monitoring tool are the significant quantities of time needed by the radiologist to actually measure the size of the lesions, and the poor reproducibility of these manual measurements. A CAD system for automatic image analysis improves clinical efficiency and standardizes the lesion measurements. Multiple sclerosis is a disease well suited for automated analysis. The segmentation algorithm devised classifies normal and abnormal brain structures and measures the volume of multiple sclerosis lesions using fuzzy c-means clustering with incorporated spatial (sFCM) information. First, an intracranial structures mask in T1 image data is localized and then superimposed in FLAIR image data. Next, MS lesions are identified by sFCM and quantified within a predefined volume. The initial validation process confirms a satisfactory comparison of automatic segmentation to manual outline by a neuroradiologist and the results will be presented.

Results indicated elevated levels of Cadmium (Cd, Chromium (Cr, Copper (Cu, lead (Pb, Manganese (Mn, Nickel (Ni and Zinc (Zn ranging from 0.01-1.20, 0.05-0.52, 0.80-34.80, 0.09-4.30, 0.09-8.30, 0.05-3.94, 0.05-19.60 and 1.80-29.90 mg L-1 respectively which exceeded national recommended limits with few exceptions. Hazard Quotients (HQ and Hazard Index (HI of heavy metals were calculated and results greater than 1 indicate non-carcinogenic adverse health effects of the observed metals. A daily intake of water by the local residents could pose a potential health threat from long-term heavy-metal exposure. The risk assessment provided by this study can be beneficially used and applied for risk communication to avoid negative public health impact. Similarly, Water Safety quality assurance strategic plan should be developed to safeguard source, water and public health within the mining community.

    Full Text Available ABSTRACTThe massive examination leakages, demand for gratification by teachers, bribe-taking by supervisors and invigilators of examinations have become a global phenomenon. This menace has resulted to general fallen standards of education and Nigeria is no exception, particularly among developing nations. Consequent upon this, all Nigerian universities have resorted to conducting post-entrance “Post-JAMB” examination/screening because of lack of confidence in the conduct of the entrance examinations. This paper proposes a model for e-Examination in Nigeria where all applicants are subjected to online entrance examination as a way of curbing the irregularities as proposed by the Joint Admissions Matriculation Board (JAMB, the body saddled with the responsibility of conducting entrance examinations into all the Nigerian universities. This model was designed and tested in Covenant University, one of the private universities in Nigeria. There were 120 questions drawn from English (30, Mathematics (30, General Science (20, Commercial Courses (20, and Religion Knowledge (20, all for one hour duration. Questionnaires were administered to the applicants at the end of the examination to assess their level of ICT literacy, ease of use of the system and the difficulties encountered.Findings revealed that the system has the potentials to eliminate some of the problems that are associated with the traditional methods of examination such as impersonation and other forms of examination malpractices. The system is easy to use and candidates can get use to it with time. The timing of examination can be spaced without compromising the quality and integrity of the examination. However, much is still desired if the system were to be adopted on a national scale, particularly in terms of infrastructural and manpower development. Similarly, the quest for e-Examination can fast track the development of e-Learning facilities in the country with improved access to education.

    OBJECTIVES: By MRI to assess the efficacy of addition of anakinra for controlling synovitis and stopping erosive progression in patients with clinically active RA despite receiving methotrexate, and to determine the predictive value of MRI for subsequent radiographic erosive progression. METHODS: 100 mg anakinra subcutaneously/day was added to the treatment of 17 patients with clinically active RA despite methotrexate. MRI of the non-dominant wrist and 2nd-5th MCP joints (OMERACT evaluation) was performed at weeks 0, 12, and 36, and radiography of both hands and wrists (modified Sharp evaluation) at weeks 0 and 36. RESULTS: MRI synovitis scores were not significantly changed. Radiography of both hands and wrists after 36 weeks showed erosive progression in 11 patients, and MRI after 12 weeks in 10 patients. Nine of 10 patients with MRI progression at 12 weeks had radiographic progression at 36 weeks. Baseline MRI synovitis and erosion scores, but no clinical/biochemical parameters, correlated significantly with subsequent erosive progression. CONCLUSION: Addition of anakinra did not significantly reduce MRI signs of synovitis, and most patients had progressive joint destruction. Baseline MRI findings predicted subsequent radiographic erosive progression. Unilateral wrist and MCP joint MRI after 12 weeks had a similar sensitivity for detection of erosive progression as bilateral hand and wrist radiography after 36 weeks.

  20. Women migrants in Nigeria.

    Makinwa-adebusoye, P K

    1994-06-01

    The prevailing notion in Nigeria is that female migration is associational migration. This survey of the towns of Ibadan, Enugu, Lagos, and Kaduna examines the need for female paid employment and the reasons for migration based on marital status among 2316 migrant women with comparisons to 1363 nonmigrant women. A primary motivation for migration is dissatisfaction with living conditions. Families are support groups providing transportation and initial reinforcement for moves to urban areas. Remittances to families in the place of origin reinforce the investment. The expectation is that women will use migration as an option for advanced education, paid employment, and increased income. The survey found that only 8.2% of migrants made the decision to migrate alone. 82.7% make migration decisions jointly with family members: husbands, parents, and other relatives. Single women were more likely to make sole decisions or decisions with parents. 94% indicated family support for the decision to migrate. About 18% of single women paid the cost of transportation and the move themselves. 70% made the move in the company of parents and other relatives. Married women's costs were underwritten by husbands, except for 9.5% who paid for it themselves. 82.6% did not have a prearranged job before migrating. The average stay ranged from three months to several years. About 33% stayed less than a year. Most migrants with wage employment in the formal sector secured their positions with the help of relatives. 55.4% of migrants in the survey stayed with relatives on arrival, 8.6% were in rented units, and 2.5% stayed in employer housing. Slightly more than 50% of migrants staying with relatives and received free board. Female migration between 1971 and 1981 was influenced by modernization and greater advancement in education. Transportation and communication improvements made it easier to migrate. The economic recession and structural adjustment measures during the 1980s stimulated female migration as a means to secure family income. 16% of migrating women did so for human capital development. The decision to migrate was heavily influenced by dissatisfaction with present living conditions. PMID:12179892

    This paper is to establish the present state of things in the country in terms of legal framework and the availability of personnel with a view to presenting an overview of proper mass disaster investigations. This is a retrospective review of mass disasters in Nigeria that occurred within the last 20 years. The study therefore reviews the state of the forensic investigation of the mass disasters as well as the efforts made to identify the victims of the disaster. The process of proper forensic investigation from the stage of evaluation of the scene and recovery process to the final identification of victims are presented to serve as a protocol for the country. The assessment of the present state of preparedness in Nigeria is also examined with a view to improving the practice to international standards. Data were retrieved from official documents from the aviation industry as well as Nigeria news reports. The standard protocols for disaster victim identification were retrieved from the guide released by the INTERPOL. The state of preparedness of the country and recommendations for improvement are presented. The Federal government and the states of the federation should without further delay put in place the process of reviewing the law of Coroner's system and provide the enabling environment for the proper forensic investigation. The training curriculum of the first responders should incorporate mass disaster investigations in order to produce efficient officers and personnel. A functional disaster victim identification (DVI) team is strongly advocated to incorporate different professionals involved in mass disaster management. PMID:25657485

  2. Insurance Market Activity and Economic Growth: Evidence from Nigeria

    2011-12-01

    Full Text Available The focus of this study is to empirically assess insurance market activities in Nigeria with the view to determining its impact on economic growth. The period of study was 1970- 2008, the study made use of insurance density measures (premium per capita as a measure for insurance market activity and real GDP for economic growth. It also employed control variables such as inflation and savings rate as other determinants of growth. The Johansen cointegration and vector error correction approach was used to estimate the relationship between the variables. All the variables used were stationary at first difference and the result showed a long term relationship existing among the variables. The hallmark finding of this study is that the insurance sector did not reveal any positively and significant affect on economic growth in Nigeria within the period of study. The result shows a low insurance market activity in Nigeria and that Nigerians have not fully embrace the insurance industry despite its importance to the growth of the economy.

    Full Text Available Background: The quality of service and success of patient care and research in most fields of medicine depend on effective collaboration between different specialties. Paediatric surgery is a relatively young specialty in Nigeria and such collaborations are desirable. This survey assesses the nature and extent of collaboration between paediatric surgery and other specialties in Nigeria. Materials and Methods: This is a questionnaire survey carried out in November 2008 among paediatric surgeons and their trainees practising in Nigeria. Questionnaires were distributed and retrieved either by hand or e-mailing. The responses were then collated and analysed using the SPSS 17.0. Results: Forty-seven respondents were included in the survey. Forty-five (95.7% respondents thought that there was inadequate collaboration and that there was a need for an increased collaboration between paediatric surgery and other specialties. Anaesthesia, paediatrics and radiology are among the specialties where collaborations were most required but not adequately received. Collaboration had been required from these specialties in areas of patient care, training and research. Reasons for inadequate collaboration included the paucity of avenues for inter-specialty communication and exchange of ideas 33 (70.3%, lack of awareness of the need for collaboration 32 (68.1%, tendency to apportion blames for bad outcome 13 (27.7%, and mutual suspicion 8 (17%. Conclusion: There is presently inadequate collaboration between paediatric surgery and other specialties in Nigeria. There is a need for more inter-specialty support, communication, and exchange of ideas in order to achieve desirable outcomes.

    This study was designed to investigate the human health risk through consumption of seafood from contaminated sites in Kaa, B-Dere, and Bodo City all in Ogoniland. The potential non-carcinogenic health risk for consumers were investigated by assessing the estimated daily intake and target hazard quotients for Cr, Cd, Zn, Pb, Mn, and Fe while carcinogenic health effect from Cr, Cd, and Pb was also estimated. The estimated daily intake from seafood consumption was below the threshold values for Cr, Mn, and Zn while they exceeded the threshold for Cd, Pb, and Fe. The target hazard quotients for Zn and Cr were below 1. Target hazard quotients values for Cd, Pb, Mn, and Fe were greater than 1 except for Fe level in Liza falcipinis from Kaa. Furthermore, estimation of carcinogenic risk for Cr in all samples under study exceeded the accepted risk level of 10E-4. Also, Cd carcinogenic risk level for L. falcipinis and Callinectes pallidus collected from B-Dere and C. pallidus collected from Bodo City was 1.1E-3 which also exceeded the accepted risk level of 10E-4 for Cd. Estimation of carcinogenic risk for Pb was within the acceptable range of 10E-4. Consumers of seafood from these sites in Ogoniland may be exposed to metal pollution. PMID:26635021

    Full Text Available The activity concentration of natural radionuclides in soil samples from industrial dumpsites in Sango-Ota were determined using gamma-ray spectrometry with NaI(Tl detector. The mean activity concentration of 226 Ra, 232 Th and 40 K was 3.0 ± 1.2, 33.3 ± 9.8 and 122.1 ± 20.6 Bqkg?1 , respectively. Radium equivalent activities were calculated to assess the hazards arising from the use of the soil sample in agriculture. All the calculated values were lower than the world average. The mean concentration of heavy metals in the soil samples were 33.6, 2.9, 3.8, 2.7, 48.9, 1,5, 34.5 and 0.8 mg l -1 for Cu, Mg, Ca, P, Fe, Pb, Zn and Cd, respectively. The concentrations of Cd, Cu and Pb were higher than the natural permissible range in soil. Therefore, the government should discourage the use of the soil around dumpsites for planting because of the presence of heavy metals in the sites.

    Full Text Available Long-term effects on soil chemical properties and plant composition of a crude oil polluted site were assessed using random surface soil samples and quantitative vegetation data collection methods. Results showed that total hydrocarbon content (542.50±28.58 mg kg–1 and total organic carbon (1.06±0.18% of polluted site were significantly (p = 0.05 higher than the unpolluted site of 27.90±22.10 mg kg–1 and 0.73±0.06%, respectively. Plant species composition showed that Aspillia busei and Heterotis rotundofolia were abundant at polluted site and absent in unpolluted site while Panicum maximum and chromolaena odoratum were absent in polluted site. Species diversities records were 0.37 (polluted site and 0.64 (unpolluted. Aspillia busei recorded the highest frequency of occurrence (90% and density (28.2 m–2 in the polluted site while Starchytarpheta jamaicensis recorded the highest frequency of occurrence (40% and Andropogon tectorum the highest density (3.9 m–2 at the unpolluted site. It can be concluded that the effects of crude oil pollution persists for a long time and negatively affect soil chemical properties, plant species composition and species diversity.

    Full Text Available AIM: The aim of this study was to determine if in-patients in some selected Nigeria hospitals are at risk of developing pressure sore and to determine the preventive techniques adopted by Health Care Professionals. METHOD: A questionnaire was used for this study and it was divided into two parts. The part A is a structured questionnaire that took care of socio-demographic data and preventive techniques while part B is the Braden Scale which was used to assess the risk of developing pressure ulcer. Three hundred and eighteen (318 In-patients in five Nigeria purposively selected hospitals in southwest Nigeria volunteered to participate in this study. The statistical method that was employed was descriptive statistics. RESULTS: The result of the study showed that In-patients in the selected hospitals are “at risk” of developing pressure ulcers. Also, General Practitioners (50.47% and nursing staff (49.52% mostly prescribed at least one of the preventive techniques while few (31.23% reported that physiotherapists prescribed at least one of the preventive techniques. However, a considerable number of the patients (35.02% were never informed by any of the health staff on preventive measures. CONCLUSION: It was concluded that In-patients in Nigeria hospitals are “at risk” of developing pressure ulcers and that health care providers in Nigeria are not prescribing adequate preventive techniques to prevent pressure ulcers.

    This report summarizes the activities and accomplishments of NREL`s Solar Radiation Resource Assessment Project during fiscal year 1991. Currently, the primary focus of the SRRAP is to produce a 1961--1990 National Solar Radiation Data Base, providing hourly values of global horizontal, diffuse, and direct normal solar radiation at approximately 250 sites around the United States. Because these solar radiation quantities have been measured intermittently at only about 50 of these sites, models were developed and applied to the majority of the stations to provide estimates of these parameters. Although approximately 93% of the data base consists of modeled data this represents a significant improvement over the SOLMET/ERSATZ 1952--1975 data base. The magnitude and importance of this activity are such that the majority of SRRAP human and financial in many other activities, which are reported here. These include the continued maintenance of a solar radiation monitoring network in the southeast United States at six Historically Black Colleges and Universities (HBCU`s), the transfer of solar radiation resource assessment technology through a variety of activities, participation in international programs, and the maintenance and operation of NREL`s Solar Radiation Research Laboratory. 17 refs.

  20. General guidelines for the assessment of internal dose from monitoring data: Progress of the IDEAS project

    International Nuclear Information System (INIS)

    In recent major international intercomparison exercises on intake and internal dose assessments from monitoring data, the results calculated by different participants varied significantly. Based on this experience the need for harmonisation of the procedures has been formulated within an EU 5. Framework Programme research project. The aim of the project, IDEAS, is to develop general guidelines for standardising assessments of intakes and internal doses. The IDEAS project started in October 2001 and ended in June 2005. The project is closely related to some goals of the work of Committee 2 of the ICRP and since 2003 there has been close cooperation between the two groups. To ensure that the guidelines are applicable to a wide range of practical situations, the first step was to compile a database of well-documented cases of internal contamination. In parallel, an improved version of an existing software package was developed and distributed to the partners for further use. A large number of cases from the database was evaluated independently by the partners and the results reviewed. Based on these evaluations, guidelines were drafted and discussed with dosimetry professionals from around the world by means of a virtual workshop on the Internet early in 2004. The guidelines have been revised and refined on the basis of the experiences and discussions in this virtual workshop. The general philosophy of the Guidelines is presented here, focusing on the principles of harmonisation, optimisation and proportionality. Finally, the proposed Levels of Task to structure the approach of internal dose evaluation are reported. (authors)

  1. Capital Gains Tan in Nigeria

    Obaje Enemaku Esq

    2012-06-01

    Full Text Available Tax is a compulsory levy imposed by the government on the incomes of taxpayers in order to pay the expenses of governance. Capital Gains Tax is a form of tax chargeable on capital gains arising from the disposal of chargeable assets. This paper examines the nature and the justification for Capital Gain Tax as a lucrative ground for raising revenue for development especially in the developing countries. In Nigeria, Capital Gain Tax is yet to yield the desired result in terms of raising revenue for the government. Our theoretical work on this subject explain reasons which includes lack of awareness, inadequate data and the high rate of inflation which has led to high incidence of avoidance of Capital Gain Tax. Arguments against capital gain tax in Nigeria are examined as well as issues, suggestions and recommendations for the effectiveness of this form of taxation. This paper recommends more aggressive awareness campaign, reduction of tax rate and even a merger of capital gain with income tax to reduce cost of collection.

A survey design was adopted in the form of a structured questionnaire which was used to collect data from 860 respondents across the six geo-political zones of Nigeria. The data was analysed using frequency distributions and cross-tabulations with the Chi-square statistic at the 0.01 level of significance. Findings revealed that while most subscribers supported the implementation of MNP in Nigeria, a significant proportion believed that tariffs would not drop as long as the power problem continued. Furthermore, it was found that of the demographic variables, age had the strongest influence on subscriber attitudes and this was identified as a strategic focus for network operators and the regulator y authority.

    International Nuclear Information System (INIS)

    To woo householders into harnessing the cooking energy potential of biogas in order to solve the perennial cooking energy problems at household level in Nigeria, this paper carried out the engineering design requirement, and used the discounted cash flow micro-economic assessments to evaluate the 6.0 m3 family-sized biogas project in Nigeria. The project has an initial investment cost of 41,088 Naira, annual expenditure of 5909 Naira and an annual benefit of 13,347 Naira. The NPV, IRR, B/C and payback period of financial analysis are 0.050 million Naira, 17.52%, 2.26 and 6.6 years respectively. This shows that the 6.0 m3 family-sized biogas project using cattle dung as substrate in Nigeria has a good economic potential. (author)

    Traditionally, assessment of functional and cognitive status of individuals with dementia occurs in brief clinic visits during which time clinicians extract a snapshot of recent changes in individuals’ health. Conventionally, this is done using various clinical assessment tools applied at the point of care and relies on patients’ and caregivers’ ability to accurately recall daily activity and trends in personal health. These practices suffer from the infrequency and generally short durations of visits. Since 2004, researchers at the Oregon Center for Aging and Technology (ORCATECH) at the Oregon Health and Science University have been working on developing technologies to transform this model. ORCATECH researchers have developed a system of continuous in-home monitoring using pervasive computing technologies that make it possible to more accurately track activities and behaviors and measure relevant intra-individual changes. We have installed a system of strategically placed sensors in over 480 homes and have been collecting data for up to 8?years. Using this continuous in-home monitoring system, ORCATECH researchers have collected data on multiple behaviors such as gait and mobility, sleep and activity patterns, medication adherence, and computer use. Patterns of intra-individual variation detected in each of these areas are used to predict outcomes such as low mood, loneliness, and cognitive function. These methods have the potential to improve the quality of patient health data and in turn patient care especially related to cognitive decline. Furthermore, the continuous real-world nature of the data may improve the efficiency and ecological validity of clinical intervention studies. PMID:26113819

  6. The quest for nuclear technology and the challenges of knowledge management in Nigeria

    International Nuclear Information System (INIS)

    Full text: The setting up of the Federal Radiation panel in early sixties signified the awareness in Nigeria of the application and dangers of nuclear radiation. This initiative was further reinforced with the establishment of the Federal Radiation Protection Service in 1964, that same year Nigeria joined the IAEA thus opening a window for technical assistance in nuclear application for national development. The enactment of the Nigeria Atomic Energy Commission Act in 1976, the launching of National Nuclear Programme and the designation of Obafemi Awolowo University and Ahmadu Bello University (ABU) Zaria as centers of excellence in nuclear research in 1977 marked the beginning of a systematic development of manpower and physical infrastructure for the peaceful application of nuclear science and technology in Nigeria. Within the first ten years, the centers trained over 60 Nigerians up to PhD level in different areas of nuclear science and engineering in institutions in Europe and America. Now the pioneering scientists train Doctorate and masters degree students locally at the centres. Currently, research, training and application of nuclear science and technology are carried out in 36 Federal and State Universities in departments such as physics, chemistry, geology and agriculture. In 2003, the center at ABU produced 8 MSc, 6 PhD thesis and published 15 research papers. We also have 27 specialized research institutes in areas of agriculture, health, water resources, petroleum and environment, a number of health institutions where some form of ionizing radiation are used; with thousands of diagnostic X-ray units and five radiotherapy centres in operation. The progress made so far in the last 40 years is quite modest, nuclear science and technology are now widely used in research, development and practical application for national development. It is worthy of note here that IAEA has been involved and played significant role in our quest for nuclear technology. A major challenge arising from this development, is the collection, harvest and disseminating of the widest possible information and knowledge accumulated over the years. The resolution on nuclear knowledge by the IAEA General Conference in 2002 and 2003 and the recommendations and new guidelines by an INIS external evaluation panel, has given us the impetus to evaluate our activities and reposition the INIS center toward responding to this challenge and the emerging trend in knowledge management. In doing so we refocus our mind on two key areas of INIS operation in our Centre; Collection of relevant material and preparation of input; Our membership obliged us to make contribution commensurate with the level of activities within our borders. INIS has developed over the years as the World's leading information system in nuclear science and technology through the coordination of IAEA and the cooperation of member states. Promotional Activities are fashioned out to facilitate the attainment of the goals set for nuclear energy in the national energy policy within the framework of our National Development Objectives, through the establishment of an information resource capable of meetings the needs of our scientists and engineers. A necessary step toward this end is to build a network of universities and research institutes in nuclear science, that will be use to pool, analyze and share national nuclear knowledge and experience, address preservation and promotion of knowledge, maintain competence and avoid duplication wherever necessary. Target sets for 2004 on the two key areas are: Contribute 0.5-1.0% of the total input to INIS as against 0.0159% in 2003; Reach out to 5000 potentials users; Digitization of Environmental Impact Assessment Report on Energy Project (1995-2003). Steps taken so far: Assignment of 4 staff, 3 workstations and a scanner with OCR capability for the INIS center; Capacity building for input preparation using available resources from INIS secretariat such as INIS CBT; A survey covering larger percentage of academic departments especially physics h

    In 1992, the US Postal Service (USPS) entered into an Interagency Agreement with the Department of Energy (DOE) whereby DOE would provide technical assistance in support of the USPS Radon Assessment and Mitigation Program. To aid in this effort, DOE tasked the Hazardous Waste Remedial Actions Program (HAZWRAP), which is managed by Martin Marietta Energy Systems, Inc., for DOE under contract AC05-84OR21400. Since that time, HAZWRAP has developed and finalized the sampling protocol, mitigation diagnostic protocol, and the quality assurance and quality control procedures. These procedures were validated during the Protocol Validation (1992-1993) and Pilot Study (1993-1994) phases of the program. To date, HAZWRAP has performed approximately 16,000 radon measurements in 250 USPS buildings. Mitigation diagnostics have been performed in 27 buildings. Thus far, 13% of the measurements have been above the Environmental Protection Agency action level of 4 pCi/L. This report summarizes the pilot program radon testing data and mitigation diagnostic data for 22 sites and contains recommendations for mitigation diagnostics.

    Full Text Available Companies are increasingly conducting life cycle assessments (LCA of their products to understand potential product impacts on the environment, prioritize areas of innovation to create more sustainable products, and determine valid claims. This case study shows the results of product innovation by comparing an older (2007 and new (2013 version of a common hygiene product in Europe and the U.S. The standard methodology follows the ISO 14040/44 Guidelines for LCA. Results are reported for the impact indicators with high relevance for the product category: primary energy, global warming, particulates, agricultural land occupation, fossil fuel depletion, and solid waste generation. Generally, raw material supply chains for product and packaging contribute most (up to 82% to the calculated environmental impact indicators. Improvements vs. the 2007 baby wipe range between 4% and 14% in Europe and between 15% and 36% in the U.S. The improvement is driven by a new substrate technology that provides more surface area for cleaning, which results in lower use of resources. This case study illustrates three key environmental drivers behind this innovation: the corporate focus on R&D capability to design for environmentally improved products, the increased interest from retailers and consumers requiring accurate and relevant information on the performance and sustainability of products, and the company’s interest in deeper technical understanding of contributions from upstream material and process innovations on a product’s environmental profile.

    Taking the issue of tumor categorization a step forward and establish molecular imprints to accompany histopathological assessment is a challenging task. This is important since often patients with similar clinical and pathological tumors may respond differently to a given treatment. Protease-activated receptor-(1) (PAR(1)), a G protein-coupled receptor (GPCR), is the first member of the mammalian PAR family consisting of four genes. PAR(1) and PAR(2) play a central role in breast cancer. The release of N-terminal peptides during activation and the exposure of a cryptic internal ligand in PARs, endow these receptors with the opportunity to serve as a "mirror-image" index reflecting the level of cell surface PAR(1&2)-in body fluids. It is possible to use the levels of PAR-released peptide in patients and accordingly determine the choice of treatment. We have both identified PAR(1) C-tail as a scaffold site for the immobilization of signaling partners, and the critical minimal binding site. This binding region may be used for future therapeutic modalities in breast cancer, since abrogation of the binding inhibits PAR(1) induced breast cancer. Altogether, both PAR(1) and PAR(2) may serve as molecular probes for breast cancer diagnosis and valuable targets for therapy. PMID:21318117

    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 The world is witnessing a rapid and progressive transformation as a result of IT revolution, which has predominated all aspects of societal development. One of such transformations has manifested in the form of digital libraries. The evolution of digital libraries has ensured the emergence of global networked environment that has dramatically changed the face of libraries, their functions, services as well as their storage and delivery systems. In this perspective, the paper examines the status of digital libraries in Nigeria. It also analyzes the Nigerian information environment within the context of an escalating situation in terms of funding, infrastructure, and ICT policy. The paper concludes that if digital libraries in Nigeria are to survive, drastic and progressive action needs to be taken to overcome some the aforementioned issues. Governments and sponsoring bodies of libraries must provide all the necessary funding and support for library development especially the digital libraries.

  16. Democracy in Nigeria: the challenge of infectious disease control

    Full Text Available The relationship between democracy and health outcomes has been the focus of recent research interest [1,2]. With an estimated 140 million people, Nigeria is the most populous country in Africa. In May 2007, it marked eight years of unbroken civilian government, the longest period of civilian rule in its post-independence history with the noticeably peaceful handover of power from President Obasanjo to President Yar’adua. These eight years of relative peace and democratic governance in Nigeria have seen changes in the economy with steady growth, a large reduction in external debt, and structural reforms of the financial and telecommunications sectors. These changes, however, have had little impact on the lives of ordinary Nigerians [3]. In the health sector, progress has been slow and many challenges remain: from weak health systems to tackling HIV/AIDS; from improving immunization coverage (which in the past has impeded the global goal of eradicating polio to implementing the new International Health Regulations (IHR; from achieving the Millennium Developmental Goals (MDGs to preparing for pandemic flu. We examine the progress made and challenges faced from an infectious diseases perspective in Nigeria over the past eight years.In northern Nigeria in 2003, concerns about vaccine safety, i.e. rumours that the polio vaccine caused sterility, led to a halt in polio immunization. This led to the resurgence of the disease in Nigeria, and the re-infection of several neighbouring countries, setting back the entire global eradication programme [4]. While the last two years have witnessed a renewed response with reinvigorated vaccination campaigns, the disease has persisted and Nigeria remains one of four countries in which the circulation of the wild poliovirus has never been interrupted, recording the highest number of confirmed polio cases in 2006 and 2007 [5]. Routine immunisations for other vaccine preventable diseases remain below 50% (most recent data 2005 [6]. Outbreaks of measles, for which a cheap, safe and easily administered vaccine has been available for two decades, continue to occur with unacceptable mortality rates [7].In February 2006, the first case of highly pathogenic H5N1 avian influenza in domestic birds in Africa was reported from a poultry farm in Nigeria [8]. The case took 5 weeks to be confirmed. Health officials were quickly overwhelmed by the challenge of culling thousands of chickens, responding too late and with too little as the disease spread. Each week brought new anxiety and weird responses [9]. The response to this outbreak provided a troubling illustration of what can happen when H5N1 hits a developing country with a weak health care system and limited capacity in infectious disease control.Nigeria has the third largest number of people living with HIV in the world [10]. In 1999 the new civilian government set up a National Action Committee on AIDS (NACA charged with coordinating various activities related to the prevention and control of HIV/AIDS in the country. The committee has recently been transformed by legislative act into a statutory agency. The prevalence rate based on national sentinel surveys rose from 1.8 per cent in 1991 to 5.8 % in 2001 but in 2006 it was estimated at 3.9 per cent [11]. However, marked variation within the country persists with prevalence rates as high as 12 per cent in some states [12]. In 2005, the Nigerian government committed to universal provision of free antiretroviral therapy, the implementation of which has been largely funded by the Global Fund, PEPFAR [12] and the World Bank. While some progress has been made, with an estimated 92,000 people currently on treatment [12], poor management, shoddy coordination, and capacity issues have impeded further progress in this area.In Nigeria, there is no broad technical agency with the capacity for the surveillance and response to infectious disease. This responsibility lies with technocrats in the Ministry of Health. Most surveillance and response activities are managed via disease specific v

    Full Text Available AIM: To evaluate the relationship between liver stiffness and duration of infection in blood transfusion-associated hepatitis C virus (HCV patients with or without hepatocellular carcinoma (HCC. METHODS: Between December 2006 and June 2008, a total of 524 transfusion-associated HCV-RNA positive patients with or without HCC were enrolled. Liver stiffness was obtained noninvasively by using Fibroscan (Echosens, Paris, France. The date of blood transfusion was obtained by interview. Duration of infection was derived from the interval between the date of blood transfusion and the date of liver stiffness measurement (LSM. Patients were stratified into four groups based on the duration of infection (17-29 years; 30-39 years; 40-49 years; and 50-70 years. The difference in liver stiffness between patients with and without HCC was assessed in each group. Multiple linear regression analysis was used to determine the factors associated with liver stiffness. RESULTS: A total of 524 patients underwent LSM. Eight patients were excluded because of unsuccessful measurements. Thus 516 patients were included in the current analysis (225 with HCC and 291 without. The patients were 244 men and 272 women, with a mean age of 67.8 ± 9.5 years. The median liver stiffness was 14.3 kPa (25.8 in HCC group and 7.6 in non-HCC group. The patients who developed HCC in short duration of infection were male dominant, having lower platelet count, with a history of heavier alcohol consumption, showing higher liver stiffness, and receiving blood transfusion at an old age. Liver stiffness was positively correlated with duration of infection in patients without HCC (r = 0.132, P = 0.024 but not in patients with HCC (r = -0.103, P = 0.123. Liver stiffness was significantly higher in patients with HCC than in those without in each duration group (P < 0.0001. The factors significantly associated with high liver stiffness in multiple regression were age at blood transfusion (P < 0.0001, duration of infection (P = 0.0015, and heavy alcohol consumption (P = 0.043 CONCLUSION: Although liver stiffness gradually increases over time, HCC develops in patients with high stiffness value regardless of the duration of infection.

The overall prevalence of neonatal thrombocytopenia was 53.0%. Mild thrombocytopenia (platelet count 51–100 × 109/L was found in 39.4% of the neonates, 12.1% had moderate thrombocytopenia (platelet count 30–50 × 109/L, while severe thrombocytopenia (platelet count <30 × 109/L was detected in 1.5% of the neonates. Of these, 84.84% of the cases occurred within 72 hours (early onset. The most common clinical diagnosis among the neonates was severe birth asphyxia (33.3%, followed by neonatal jaundice (19.7%, neonatal sepsis (16.7%, low birth weight (13.6%, anemia and bleeding (6.1%, and other clinical conditions (10.6%. There was no association between clinical diagnosis and thrombocytopenia (Fisher’s exact test = 10.643; P = 0.923.Conclusion: There is a high prevalence of early onset neonatal thrombocytopenia cases in this region of Nigeria, the majority of which are mild in nature. There is a need to define a safer lower limit for platelet count and to determine which neonates will benefit from treatment.Keywords: neonatal thrombocytopenia, platelet count, thrombocytopenia, Port Harcourt, Nigeria

    2015-01-01

    Nigeria evidently has huge potentials to develop a strong astronomy community. Much of the strength lies in the great number of intelligent students with the potential of becoming good astronomers. Sadly, astronomy development in Nigeria has stagnated in the past decades owing to poor funding and/or indifferent attitude of the funding bodies, research-unfriendly environment, and non-existence of facilities. Currently, efforts toward fuelling advancement in astronomy are focused on building 'critical mass', establishing collaborations with universities/astronomy institutes outside Nigeria, converting out-of-use communication antennas into radio telescopes, and acquiring out-of-use telescopes for educational and low-level research purposes.

  5. Biofuels development and adoption in Nigeria: Synthesis of drivers, incentives and enablers

    International Nuclear Information System (INIS)

    Biofuels development and adoption in Nigeria has progressed significantly since the inception of the country's biofuel program in 2007. The rapid growth of the biofuels subsector in Nigeria inspired this review which aims at identifying the key drivers, agents, enablers, incentives and objectives driving the development. From the upstream to the downstream sub-sectors, there is an increasing entry of players and participants (private and public investors). This paper aims to explore the underlining drivers, enablers and incentives promoting the investments and participations in biofuels development, adoption and utilization in Nigeria. The research sourced data from basically secondary sources and undertook desk review of available information. The drivers identified are classified into the endogenous and exogenous categories.

    Full Text Available Poverty is one of the most common characteristics of the third world countries including Nigeria. National Economic Empowerment and Development Strategy (NEEDS is a reform agenda by Nigerian Government modeled on the IMF’s poverty reduction and growth facility to achieve some macroeconomic goals of stability, poverty alleviation, wealth creation, and employmentgeneration. This paper investigates the extent to which the goal of poverty reduction has been achieved after the first phase of its implementation (2004-2007.The paper adopted the content analysis of library materials, publications and other documented researches pertaining to the subject-matter. The paper concludes that NEEDS has not made a significant impact on Nigeria’s infrastructures and standard of living of the majority and therefore status of poverty remain at an alarming rate. The failure of NEEDS to significantly generate employment and reduce poverty has been attributed largelytoweak institutional frameworks andlack of political will in the Nigerian state. To achieve poverty reduction and economic progress in Nigeria, majority of Nigerians must have access to quality education and the leadershipmust be truly committed to the economic reform agenda by encouraging development of stronger State institutions and creating an enabling investment environment.

  7. Correlation with neuropsychological assessment and SPM analysis of brain perfusion SPECT in patients with progressive supranuclear palsy

    International Nuclear Information System (INIS)

    Progressive supranuclear palsy (PSP) is a degenerative condition of unknown aetiology that produces an akinetic-rigid form of parkinsonism characterised by early falls, dementia and abnormalities of extraocular movements. The patterns of decreased regional cerebral blood flow and cognitive impairment in PSP compared with normal control have been insufficiently investigated and a limited number of studies have been performed. We evaluated clinical symptoms, functional neuroimaging study using Tc-99m HMPAO SPECT and neuropsychological profiles in patients with PSP. Eleven patients with PSP diagnosed by the clinical criteria of National Institute of Neurological Disorders and Stroke and the Society for PSP (NINDS-SPSP) (mean age: 70.5±5.6 years, educational period: 4.5±4.7 years) and age-matched 10 healthy control subjects (mean age: 68.1±4.5 years, educational period: 6.5±4.1 years) participated in this study were participated. All patients were given a neurologic examination, brain MRI and cerebral perfusion SPECT using Tc-99m HMPAO. We concomittently evaluated several cognitive profiles using the Seoul Neuropsychological Screening Battery. SPM analysis of the SPECT image showed significant perfusion deficits in the left inferior frontal gyrus, left caudate nucleus, left middle frontal gyrus and cingulate gyrus in the patients with PSP compared with age-matched healthy control (uncorrected p<0.01). On neuropsychological assessment, cognitive deficits on verbal and visual memory, word fluency and frontal executive functions were prominent in most patients with PSP compared with healthy control subjects. Our findings suggest that measurement of regional cerebral blood flow by perfusion SPECT and voxel-based SPM analysis with neuropsychological assessment are useful to understanding the correlation between perfusion deficits and abnormal cognitive profiles in patients with PSP

  10. MELCOR 1.8.2 assessment: The MP-1 and MP-2 late phase melt progression experiments

    International Nuclear Information System (INIS)

    MELCOR is a fully integrated, engineering-level computer code being developed at Sandia National Laboratories for the USNRC, that models the entire spectrum of severe accident phenomena in a unified framework for both BWRs and PWRs. As a part of an ongoing assessment program, MELCOR has been used to model the MP-1 and MP-2 experiments, which provided data for late-phase melt progression in PWR geometries. Core temperature predicted by MELCOR were within 250--500 K of measured data in both MP-1 and MP-2. Relocation in the debris bed and metallic crust regions of MP-2 was predicted accurately compared to PIE data. Temperature gradients in lower portions of the test bundle were not predicted well in both MP-1 and MP-2, due to the lack of modeling of the heat transfer path to the cooling jacket in those portions of the test bundles. Fifteen sensitivity studies were run on various core (COR), control volume hydrodynamics (CVH) and heat structures (HS) package parameters. No unexpected sensitivities were found, and in particular there were no sensitivities to reduced time step, finer nodalization or to computer platform. Calculations performed by the DEBRIS and TAC2D codes for MP-1 and MP-2 showed better agreement with measured data than those performed by MELCOR. This was expected, through, due to the fully 2-dimensional modeling used in the other codes

  14. Koranic education and militant Islam in Nigeria

    Science.gov (United States)

    Winters, Clyde Ahmad

    1987-06-01

    In this article the author outlines and discusses the influence of Koranic schools, and their students ( almagiri) on the rise of fundamentalism and the spreading of militant Islam in Northern Nigeria. The author contends that while Islamic fundamentalism is the banner of both the Western-oriented Muslims and traditional Nigerian Muslims, it differs in expression in Northern Nigeria. The article shows that these differences result from the influence of the Koranic schools on the traditional teachers ( ulama) and their students on the one hand, and Western universities, Wahhabi Arabs, and Western-oriented teachers and their students on the other. The origins of the Koranic school curriculum in Nigeria, the training of traditional Muslim teachers, and the lifestyle of the students are discussed. The author shows how certain socialization patterns found in the Koranic schools and `almagiri' system seem congruent with the political attitudes and values stressed by spokesmen of militant Islamic sects in Northern Nigeria.

  16. Using Thoracic Ultrasound to Accurately Assess Pneumothorax Progression During Positive Pressure Ventilation : A Comparison with Computed Tomography

    DEFF Research Database (Denmark)

    Oveland, Nils Petter; Lossius, Hans Morten

    2012-01-01

    ABSTRACT OBJECTIVES While thoracic ultrasonography accurately determines the size and extent of occult pneumothoraces (PTXs) in spontaneously breathing patients, there is uncertainty about patients receiving positive pressure ventilation. We compared the lung point (i.e. the area where the collapsed lung still adheres to the inside of the chest wall) using the two modalities ultrasound (US) and computed tomography (CT), to determine whether US can reliably be used to assess PTX progression in a positive pressure ventilated porcine model. METHODS Air was introduced in incremental steps into five hemithoraces in three intubated porcine models. The lung point was identified on US imaging and referenced against the lateral limit of the intrapleural air space identified on the CT. The distance from the sternum to the lung point (S-LP) was measured on the CT scans and correlated to the insufflated air volume. RESULTS The mean total difference between the 131 US and CT lung points was 6.8 mm (standard deviation ± 7.1 mm and range 0.0-29.3 mm). A mixed-model regression analysis showed a linear relationship between the S-LP distances and the PTX volume (p <0.001). CONCLUSIONS In an experimental porcine model, we found a linear relation between the PTX size and the lateral position of the lung point. The accuracy of thoracic US for identifying the lung point (and thus the PTX extent) was comparable to that of CT imaging. These clinically relevant results suggest that US may be safe and accurate in monitoring PTX progression during positive pressure ventilation.1Department of Research and Development, Norwegian Air Ambulance Foundation, Droebak, Norway, nils.petter.oveland@norskluftambulanse.no, hans.morten.lossius@norskluftambulanse.no2Department of Anesthesiology and Intensive Care, Stavanger University Hospital, Stavanger, Norway, nils.petter.oveland@norskluftambulanse.no3Department of Surgical Sciences, University of Bergen, Bergen, Norway, hans.morten.lossius@norskluftambulanse.no4Faculty of Health Sciences, Institute of Clinical Medicine, Aarhus University, Aarhus, Denmark. kristianwemmelund@gmail.com, sloth@dadlnet.dk5Department of Radiology, Stavanger University Hospital, Stavanger, Norway, paalst@hotmail.com6Department of Anesthesiology and Intensive Care, Aarhus University Hospital, Aarhus, Denmark. lars.knudsen.dk@gmail.com, sloth@dadlnet.dkCorresponding author: Nils Petter Oveland, MD, Department of Research and Development, Norwegian Air Ambulance Foundation, Mailbox 94, 1441 Droebak, Norway E-mail: nils.petter.oveland@norskluftambulanse.no.

  5. Law, religion and human rights in Nigeria

    Scientific Electronic Library Online (English)

    Enyinna S, Nwauche.

    Full Text Available This paper explores the relationship between law, religion and human rights in Nigeria. The level and intensity of religious strife in Nigeria justify this inquiry, whose aim should be the design of a framework that enables individuals to enjoy the freedom of religion and ensures that religious conf [...] licts are managed in Nigeria's multi-ethnic and multi-religious context. Almost a decade to the introduction of Islamic criminal law in the 12 northern states of Nigeria, there is no longer any doubt that religion is fundamental to the survival of Nigeria. The basic thesis of this paper is that the key to understanding the relationship between law, religion and human rights in Nigeria lies in the unacknowledged dominance of Islam and Christianity, which I characterise as de facto state religions, and the resulting neglect of other religions. It is this reality, its denial and misunderstanding of attendant constitutional obligations that define the relationship between the Nigerian state and religion.

  9. Transparency in Nigeria's public pharmaceutical sector: perceptions from policy makers

    Kohler Jillian C

    2009-10-01

    Full Text Available Abstract Background Pharmaceuticals are an integral component of health care systems worldwide, thus, regulatory weaknesses in governance of the pharmaceutical system negatively impact health outcomes especially in developing countries 1. Nigeria is one of a number of countries whose pharmaceutical system has been impacted by corruption and has struggled to curtail the production and trafficking of substandard drugs. In 2001, the National Agency for Food and Drug Administration and Control (NAFDAC underwent an organizational restructuring resulting in reforms to reduce counterfeit drugs and better regulate pharmaceuticals 2. Despite these changes, there is still room for improvement. This study assessed the perceived level of transparency and potential vulnerability to corruption that exists in four essential areas of Nigeria's pharmaceutical sector: registration, procurement, inspection (divided into inspection of ports and of establishments, and distribution. Methods Standardized questionnaires were adapted from the World Health Organization assessment tool and used in semi-structured interviews with key stakeholders in the public and private pharmaceutical system. The responses to the questions were tallied and converted to scores on a numerical scale where lower scores suggested greater vulnerability to corruption and higher scores suggested lower vulnerability. Results The overall score for Nigeria's pharmaceutical system was 7.4 out of 10, indicating a system that is marginally vulnerable to corruption. The weakest links were the areas of drug registration and inspection of ports. Analysis of the qualitative results revealed that the perceived level of corruption did not always match the qualitative evidence. Conclusion Despite the many reported reforms instituted by NAFDAC, the study findings suggest that facets of the pharmaceutical system in Nigeria remain fairly vulnerable to corruption. The most glaring deficiency seems to be the absence of conflict of interest guidelines which, if present and consistently administered, limit the promulgation of corrupt practices. Other major contributing factors are the inconsistency in documentation of procedures, lack of public availability of such documentation, and inadequacies in monitoring and evaluation. What is most critical from this study is the identification of areas that still remain permeable to corruption and, perhaps, where more appropriate checks and balances are needed from the Nigerian government and the international community.

    2015-01-01

    Background While the Nigerian government has made progress towards the Millennium Development Goals, further investments are needed to achieve the targets of post-2015 Sustainable Development Goals, including Universal Health Coverage. Economic evaluations of innovative interventions can help inform investment decisions in resource-constrained settings. We aim to assess the cost and cost-effectiveness of maternal care provided within the new Kwara State Health Insurance program (KSHI) in rural Nigeria. Methods and Findings We used a decision analytic model to simulate a cohort of pregnant women. The primary outcome is the incremental cost effectiveness ratio (ICER) of the KSHI scenario compared to the current standard of care. Intervention cost from a healthcare provider perspective included service delivery costs and above-service level costs; these were evaluated in a participating hospital and using financial records from the managing organisations, respectively. Standard of care costs from a provider perspective were derived from the literature using an ingredient approach. We generated 95% credibility intervals around the primary outcome through probabilistic sensitivity analysis (PSA) based on a Monte Carlo simulation. We conducted one-way sensitivity analyses across key model parameters and assessed the sensitivity of our results to the performance of the base case separately through a scenario analysis. Finally, we assessed the sustainability and feasibility of this program’s scale up within the State’s healthcare financing structure through a budget impact analysis. The KSHI scenario results in a health benefit to patients at a higher cost compared to the base case. The mean ICER (US$46.4/disability-adjusted life year averted) is considered very cost-effective compared to a willingness-to-pay threshold of one gross domestic product per capita (Nigeria, US$ 2012, 2,730). Our conclusion was robust to uncertainty in parameters estimates (PSA: median US$49.1, 95% credible interval 21.9–152.3), during one-way sensitivity analyses, and when cost, quality, cost and utilization parameters of the base case scenario were changed. The sustainability of this program’s scale up by the State is dependent on further investments in healthcare. Conclusions This study provides evidence that the investment made by the KSHI program in rural Nigeria is likely to have been cost-effective; however, further healthcare investments are needed for this program to be successfully expanded within Kwara State. Policy makers should consider supporting financial initiatives to reduce maternal mortality tackling both supply and demand issues in the access to care. PMID:26413788

  11. Sexual behaviour and contraceptive use among secondary school students in Ilesha south west Nigeria.

    Orji, E O; Esimai, O A

    2005-04-01

    Data from several parts of Nigeria point to increasing sexual activity among single adolescents of both sexes with progressive decreasing age at initiation and poor contraceptive use. This paper investigates the sexual behaviour and contraceptive use among teenage secondary school students in Ilesha, southwest Nigeria. This is a cross-sectional population survey of 300 male and female secondary school students within the age group of 13-19 years. The setting is secondary school coaching classes in Ilesha, southwest Nigeria. The outcome measures include prevalence of sexual activity, age at first sexual debut, circumstances leading to first sexual debut, number of sexual partners and family planning use. The result shows that out of the 300 studied, 50% were sexually active, the predominant age at first coitus was 15-19 years, and circumstances leading to sexual debut included mutual agreement, coercion and curiosity. Predominant proportion of sexually active teenagers (86.7%) did not use contraception at the time of first coitus and most of them had more than one sexual partner. The conclusion from this study is that 50% of teenage secondary school girls in this part of Nigeria are sexually active; 68.7% whom, have multiple sexual partners, and 86.7% of them did not use contraception at sexual debut. This unsafe sexual behaviour therefore put them at a great risk of acquiring STDs including HIV infection, and unwanted pregnancy. This study therefore recommends sex education/family life education for young people to encourage them to delay sexual activity as much as possible and practice safe sex when it eventually commences. There is also the need to sensitise the young people, parents, teachers, the community and all stake holders on the magnitude of the problem and to open up dialogue that will break the social, cultural and other mysteries hindering adolescents and youth reproductive health education and services in Nigeria.

  12. Assessment of baseline hemodynamic parameters within infarct progression areas in acute stroke patients using perfusion-weighted MRI

    International Nuclear Information System (INIS)

    The value of perfusion MRI for identifying the tissue at risk has been questioned. Our objective was to assess baseline perfusion-weighted imaging parameters within infarct progression areas. Patients with anterior circulation stroke without early reperfusion were included from a prospective MRI database. Sequential MRI examinations were performed on admission, 2-3 h (H2), 2-3 days (D2), and between 15 and 30 days after the initial MRI. Maps of baseline time-to-peak (TTP), mean transit time (MTT), cerebral blood volume (CBV), and cerebral blood flow (CBF) were calculated. Lesion extension areas were defined as pixels showing de novo lesions between each MRI and were generated by subtracting successive lesion masks: V0, baseline diffusion-weighted imaging (DWI) lesion; V1, lesion extension between baseline and H2 DWI; V2, lesion extension from H2 to D2 DWI; and V3, lesion extension from D2 DWI to final FLAIR. Repeated measures analysis was used to compare hemodynamic parameters within the baseline diffusion lesion and subsequent lesion extension areas. Thirty-two patients were included. Baseline perfusion parameters were significantly more impaired within the acute DWI lesion compared to lesion extension areas (TTP, p<0.0001; MTT, p<0.0001; CBF p<0.0001; CBV, p<0.0001). A significant decrease in MTT (p = 0.01) and TTP (p = 0.01) was found within successive lesion growth areas. A decreasing gradient of severity for TTP and MTT was observed within successive infarct growth areas. (orig.)

  16. The potential of nuclear energy as a primary source for clean energy in Nigeria

    International Nuclear Information System (INIS)

    Nigeria's economic development has been held back by the underdevelopment of the energy sector. Despite being one of the world's major exporters of petroleum, the country has been unable to produce enough electricity to meet domestic demand. The difficulty in harnessing fossil fuels in Nigeria for electricity generation and the connected environmental questions coupled with the acute shortages in electricity generation and supply experienced in the nation have become topics of growing national importance and international attention. Many other clean alternative sources of energy are available, but most of them are either relatively undeveloped technologically or are not yet fully utilized. In this study, nuclear reactor as a primary energy source for clean energy is suggested. An assessment of electricity generation from nuclear energy is presented. A complete Nuclear Power Programme is proposed for Nigeria. A preliminary economical and environmental impact study is performed on the proposed programme. The presented work could be used as a nucleus for a feasibility study for applying this programme in any part of Nigeria with suitable site characteristics.

    The process of fuel ethanol production from cassava root is connected to a chain of impacts on the water resource of the country where the cassava plant is grown and the root processed into fuel ethanol. The paper assesses the impact of the domestic production of 5 per cent ethanol (E5) needed under the Nigerian biofuel programme from cassava root on the water resource of Nigeria. Using the 2007 Premium Motor Spirit (PMS) consumption as the baseline, Nigeria will require about 0.49 hm{sup 3} of ethanol to blend 9.32 hm{sup 3} of PMS to arrive at the 2007 consumption estimates. The impact of the domestic production of this ethanol requirement translates to about 6.0 km{sup 3} of water; out of which about 48 per cent is green and about 52 per cent is blue. Addressing future impact typical of a developing economy like Nigeria, a three-scenario analysis was adopted to examine the impact of future growth in cassava-fuel ethanol requirement on the water resource of Nigeria, and also, the impact of improved water use on the future water footprint of E5. The projected water impact of cassava-ethanol production into the future ranges from 6.02 to 7.28 km{sup 3}, while improved water use could lower these values by about 0.04-2.35 km{sup 3} for the same period, 2010 to 2020, under the projection assumptions made.

    Full Text Available This study was conducted to assess the challenges facing 8 selected protected areas in the Sahel Savannah ecoregion and proffer solutions to these challenges in order to ensure conservation and sustainability of Nigeria’s biodiversity. Primary data were collected from randomly-selected 120 staffs using questionnaire administration from 8 Forest Reserves within Borno and Yobe states of Nigeria. A high level of encroachment of all the studied protected areas was observed, which ranged from deforestation, overgrazing, poaching to converting protected areas into farmlands. Other notable challenges include poor staffing, inadequate equipment and funding. The respondents further reported that majority of the defaulters were farmers and local people in the area, involved in such practices for their survival in the wake of harsher climate and desert encroachment in the region. This paper calls for a revision of the Government Policy on Forestry in Nigeria to allow the people own and plant forests, implementation of community based forest resources management, provision of environment and user-friendly solar powered cooking stoves and sustainable farming systems such as crop rotation, intercropping, sustainable irrigation, organic farming and agroforestry. In addition, sources of income for the locals need to be diversified, such as honey bee production.

    Full Text Available This article argued that in a pluralistic and complex society such as Nigeria the invocation of Shari'ah (Islamic law) does not augur well for the survival of democracy. The traditional belief of every Muslim is that fundamentalism has been and must continue to be rooted in the concept of theocracy [...] upon which the medieval institution of the Caliphate actually rested. Muslim political leaders challenge the agitation for a secular state in Nigeria as an inspiration by Christian theology based on Western European thought. This article argued that political and social progress in Nigeria is unrealistic without the separation of religion and politics. It was identified in this article that the separation of religion and politics does not go down well with Islamic eschatology and cosmology, because Islam's main theological drive is toward an Islamic world empire. The solution offered in this article was that emphasis should be on ensuring that any legal framework or constitutional arrangement should be one that safeguards the interests of all citizens.
