  2. Progress toward poliomyelitis eradication--Nigeria, January 2003-March 2004.

    2004-04-30

    Since the 1988 World Health Assembly resolution to eradicate poliomyelitis, three World Health Organization (WHO) regions (Americas, Western Pacific, and European) have been certified polio-free, and the number of countries where polio is endemic has decreased from 125 in 1988 to six in 2003 (Afghanistan, Egypt, India, Niger, Nigeria, and Pakistan). In 2003, Nigeria, the most populous country of the African continent (2003 population projected from 1991 census report: 125 million), reported 355 wild poliovirus (WPV) cases, accounting for 45% of cases reported globally and >80% of cases reported from the African Region (AFR). This report summarizes progress toward polio eradication in Nigeria during January 2003-March 2004. The findings indicate the urgent need to implement high-quality supplementary immunization activities (SIAs) in Nigeria to interrupt ongoing WPV transmission. PMID:15123987

  3. An assessment of Nigeria urban youth music

    Nkechi M. Christopher

    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.

  5. Nigeria.

    1987-08-01

    Nigeria, located on the western coast of Africa, is bordered by Cameroon and Chad on the east, by the Gulf of Guinea on the south, by Niger on the north, and by Benin on the west. It is the most populous country in Africa, accounting for 1 in 4 of sub-Saharan Africa's people. While only 25% of Nigerians are urban dwellers, there are 24 cities with populations that exceed 100,000. There is wonderful diversity because of the 250 ethnic groups which comprise Nigeria. The country gained full independence on October 1, 1960 as a federation of 3 regions under a constitution that provided for a parliamentary form of government. This constitution provided a substantial measure of self-government for each of the 3 regions. In 1963, Nigeria proclaimed itself a federal republic and rewrote its constitution; a 4th region was established that same year. In an effort to resolve some of the increased tensions among the ethnic groups, the 4 regions became 12 states; civil war ensued in response to the establishment of the Republic of Biafra. Biafra was defeated and then reconciliation was rapid and effective. Economic development became the focus for Nigeria. Many changes in the government occurred in the years following, and in 1983, there was a military takeover. There are currently 19 states which receive most of their revenue from the federal government according to a formula based on population and other factors. Since 1986, the country has been involved in a public discussion of its political future which will serve as a prelude to the proposed return to civilian rule in 1990. It will hopefully result in the creation of a stable political system. Since the oil boom of the 1970s, the economy of Nigeria has shifted from an agriculturally-based to an oil-based economy. They now rely on oil for more than 95% of export earnings and 70% of federal budget resources. With changes in that market, Nigeria has had to reevaluate their development plans and transportation and

    Akinyemi Olasunkanmi Oriola

    2015-06-01

    Full Text Available Aviation crashes all over the world have recently been on the high rise, stemming from negligence, mechanical faults, weather, ground control errors, pilot errors, taxing and maintenance crew errors as probable reasons for such accidents. This study models the probabilistic risk assessment of runway accident hazards in Nigeria aviation sector. Six categories of runway accident hazards with their corresponding basic events were identified and modeled using fault tree analysis method of probabilistic risk assessment. The six categories of runway accident hazards are runway surface conditions, weather conditions, collision risk, aircraft system failure, approach/takeoff procedures and human factors. The Fault Tree developed is a system of OR-gates and the weights for each hazard were derived through a domain/expert opinion. The estimated probability of occurrence of runway accident which is the top event of the Fault Tree model is 0.2624. Fault Tree Analysis; thus, identifies the most likely root causes of runway accident through importance measures. The results of the analysis show close relationship of runway accidents in Nigeria aviation sector with aircraft system failure, approach/takeoff procedures, human factor, weather conditions and collision risk.

    2013-01-01

    Full Text Available 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.

  13. An Assessment of Poverty Eradication Programme (NAPEP in Nigeria

    Adam Adem ANYEBE

    2015-06-01

    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.

  18. Assessment of some heavy elements in Galma dam, Zaria, Nigeria

    Butu, A.W

    2013-06-01

    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.

  1. Integrating community perceptions and cultural diversity in social impact assessment in Nigeria

    The Environmental Impact Assessment (EIA) Act of 1992 aimed to make the environment a central theme in development in Nigeria. Nevertheless, the extent of engagement with local cultures in the Nigerian EIA process is not statutorily guaranteed. While most EIAs in Nigeria have been for oil and gas projects in the Niger Delta, and have focused strongly on the biophysical environment, socio-economic and cultural aspects have remained marginal. The palpable neglect of community perceptions and cultural diversity in social impact assessment (SIA) in this region prone to conflict has tended to alienate the people in the decision-making process. Thus, despite claims to compliance with regulatory requirements for EIAs, and numerous purported sustainable development initiatives by international oil companies (IOCs), the region continues to face multiple sustainability challenges. This paper situates local perceptions and cultural diversity in participatory development and canvasses the integration of community perceptions and cultural diversity into SIA in the Niger Delta region. It is argued that doing this would be critical to ensuring acceptance and success of development actions within the context of local culture while also contributing to sustainable development policy in the region. - Highlights: • Nigeria EIA Act aimed to make the environment central to development in Nigeria. • Engagement with local communities in the process is not statutorily guaranteed. • SIAs in Nigeria neglect community perceptions and cultural diversity. • Article canvasses integrating community perceptions and cultural diversity in SIA. • Local acceptance in context of culture would yield sustainable development outcomes

    2013-09-01

    Full Text Available Gender and family structure are important variables in the growth and promotion of auditors in public audit firms to be partners and managing partners. Therefore, this study examines the effect of gender and family structure on the career progression of individuals in public audit firms in Nigeria. To achieve this objective, relevant primary and secondary data were used. The primary data was collected from a well structured questionnaire administered to one hundred and twenty three respondents with an average reliability of 0.83 and the secondary data from published scholarly articles. The data collected from the questionnaires were analyzed using regression, t-test, granger causality test and diagnostic test. The statistical analysis reveals the linkage between gender and technical competence of auditors in public audit firms; family structure and productivity of auditors in public audit firms; family structure and dedication to duty of auditors in public audit firms and the difference between male and female on the career progression in public audit practice. On the basis of the empirical result, the study concludes that gender of an individual does not affect the technical competence of auditors, but rather what is important is the level of education and experience of the auditor; family structure affects the productivity of auditors. This is particularly in respect to women that are married; family structure affects the dedication of auditors in public audit firms and there are differences between the growth and promotion of male or female in public audit firms. On the basis of the conclusion, useful recommendations were presented to improve the role of gender and family structure on career progression in public audit firms.

    2011-02-01

    Full Text Available The Agricultural Credit Guarantee Scheme Fund (ACGSF was established in 1977 with the aim of enhancing commercial banks’ loans to the agricultural sector in Nigeria with focus on agro-allied and agricultural production. Many years down the line, the country has witnessed poor participation in the international market with regards to non-oil export. The above stance was assessed with a view to establishing interaction between ACGSF and non-oil export using the Vector Auto-regressive (VAR technique. The study found, among others, that there exist a long-run relationship between the ACGSF and export, but the magnitude is minimal. It was therefore recommended, inter alia, that adequate infrastructural and storage facilities, which increase the shelf-life of agricultural outputs are needed to improve non-oil exports in Nigeria.

    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

  2. Assessment of utilization of wind energy resources in Nigeria

    The study critically reviews the prospects and challenges of utilizing wind energy resources for power generation in Nigeria. The various initiatives by governments and researchers were surveyed and the nation is found to sit in the midst of enormous potential for wind harvest for power generation. The far northern states, the mountainous regions and different places of the central and south-eastern states were identified as good areas for wind harvest together with the offshore areas spanning from Lagos through Ondo, Ogun, Cross-Rivers to Rivers states along the Atlantic Ocean in the south-south. Despite this great potential and huge prospect, the country is found to still suffer from serious energy crises due to her over dependence on hydropower which also is susceptible to seasonal variation in the amount of water levels at dams. There is yet to be committed wind energy project for power generation on-going in the country. Several challenges bedeviling the development and utilization of wind energy resources were identified and suggestions highlighted to help pull the nation out of this lingering energy crisis

    Christopher N Akujieze

    2014-10-01

    Full Text Available About 3.5 million tonnes of comingled municipal solid wastes (MSW are dumped annually into the landfill areas of Lagos in Nigeria with a human population of about 21 million. Upon geo-bio-chemical processes, leachates are produced which are improperly collected and may be introduced to the environment with possible insidious effects on human health. Eight (8 composite leachates samples were collected from four (4 landfills in the megacity and tested for their physiochemical parameters in order to determine their suitability for discharge into agricultural soils and groundwater systems. Geological  site investigation reveal that the landfills except Epe have significant attenuative clayey soil protection above groundwater, and can adsorb and/ or precipitate contaminants/ pollutants within its mass. Using ANOVA, juxtapositions of the Fcalculated with the  Fcritical values revealed a metal sequence of : Hg  > Zn >As >Mn >Ni >K >Pb >Cr>Cd>Fe. Also, total alkalinity> total hardness> total acidity. All the measured  anions had Fcalculated above Fcritical values and were in  the hierarchy : Chloride> sulphate> phosphate>nitrate.. Mean concentrations were in the order  : Fe>Cd>Cr>Pb>K>Ni=Mn>As>Zn>Hg. Fe also posted the highest value for standard deviation. Results of the ratios of the standard deviation to the means were in the sequence: Fe> Zn>K> Ni > Mn>Pb> Cr> Cd> Hg> As. The presence of arsenic above prescribed limits in the Epe leachate is a  major concern because the lithology is sandy, and has a reported depth of about 3m to the unconfined aquifer that adjoins the Epe Lagoon. This  expansive landfill is recommended for closure.

    2015-03-01

    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.

  6. Environment, safety and health progress assessment manual

    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

    Full Text Available Background: Cardiovascular risk factors are responsible for cardiovascular disease and rapid progression of chronic kidney disease (CKD to end-stage renal disease. Prompt evaluation, modification, and treatment of these factors in predialysis patients will reduce morbidity and mortality. This study assessed some cardiovascular risk factors in predialysis CKD patients in a tertiary hospital in Southern Nigeria. Patients and Methods: This was a case–control study that involved 76 consecutive predialysis CKD patients and 38 age-and sex-matched controls without CKD over 1 year period. Both groups were assessed for cardiovascular risk factors, and comparisons were made. A P value of <0.05 was taken as significant. Results: The mean ages of the CKD versus control group were 48.00 ± 15.28 versus 45.34 ± 15.35 years. The male:female ratio was 1.7:1 for both groups. The common etiologies of CKD in this study were hypertension 30 (39.5%, diabetes mellitus 23 (30.3%, and chronic glomerulonephritis 19 (25%. There were 38 (50% in CKD stage 3, 31 (40.8% in CKD stage 4, and 7 (9.2% in CKD stage 5. The common cardiovascular risk factors found in the CKD versus control were hypertension (96.1% vs. 42.1%, anemia (96.1% vs. 23.7%, left ventricular hypertrophy (77.6% vs. 23.7%, dyslipidemia (67.1% vs. 39.5%, hypocalcemia (60.1% vs. 18.5%, hyperphosphatemia (63.2% vs. 0%, and hyperuricemia (57.9% vs. 15.8%. These risk factors were significantly higher in CKD group. Hyperphosphatemia and hypoalbuminemia significantly increased across CKD stages 3–5. Anemia was significantly more common in males whereas dyslipidemia was more common in female CKD patients. Conclusion: Cardiovascular risk factors were highly prevalent in predialysis CKD subjects even in early stages. Hypoalbuminemia and hyperphosphatemia significantly increased across the CKD stages 3–5 whereas anemia and dyslipidemia showed significant gender differences. Cardiovascular risk factors should be

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

    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.

    2015-01-01

    Full Text Available Household poverty, especially among the farm families which are the highest population in Nigeria is still a major issue of discourse among policy makers and analysts. This study assesses the International Fund for Agricultural Development and the Federal Government of Nigeria (IFAD/FGN poverty reduction programme among farm households in Ondo State, Nigeria. The study employed a multi-stage sampling procedure. A total of 60 beneficiaries and 60 non-beneficiaries were interviewed using a structured questionnaire. Data were analyzed using a combination of descriptive statistics and Foster, Greer and Thorbecke poverty measure. The study shows that poverty incidence, depth and severity among the respondents were lower among IFAD/FGN beneficiaries than among the non-beneficiaries. Poverty incidence for beneficiaries was (0.66 against (0.79 for non-beneficiaries. This implies that about 66% and 79% of beneficiaries and non-beneficiaries were poor respectively. The poverty depth was (0.16 for beneficiaries compared to (0.24 for non-beneficiaries. The severity of poverty was mild among the beneficiaries (0.017 while it was severe among the non-beneficiaries (0.072. However, the study showed that the poverty measures (incidence, depth and severity of beneficiaries were lower compared with non-beneficiaries. Poverty related indices were still noticeable among the beneficiaries with poverty incidence of 66%, depth of 10% and severity of 1.7%. This implies that only 34% of the beneficiaries could be said to be non-poor compared with about 20% of the non-beneficiaries. This study recommends that IFAD/FGN project effort should be intensified at reducing poverty rates in the study areas using other measures such as income diversification and establishment of small scale agro-industries. More funds should also be made available for such programme and the programme should be extended to other states and rural areas of the country.

    2015-10-01

    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 This study assesses the intervention against avian influenza in Nigeria. It applied a simple compartmental model to define endemic and burn-out scenarios for the risk of spread of HPAI in Nigeria. It followed with the derivation of low and high mortality risks associated to each scenario. The estimated risk parameters were subsequently used to stochastically simulate the trajectory of the disease, had no intervention been carried out. Overall, the intervention costs US$ 41 million, which was yearly dis- bursed in various amounts over the 2006-2010 period. The key output variables (incremental net benefit, disease cost, and benefit cost ratio were estimated for each randomly drawn risk parameter. With a 12% annual discount rate, the results show that the intervention was economically justified under the endemic scenario with high mortality risk. On average, incremental benefit under this scenario amounted to US$ 63.7 million, incremental net benefit to US$27.2 million, and benefit cost ratio estimated to 1.75.

  17. An Assessment of the Impact of "The Structural Adjustment Programme" on the Poultry Industry in Nigeria

    Eronmwon Guobadia, E.

    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 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.

It was recommended that extension agents should intensify their efforts in reaching farmers and passing useful information to them in order to increase farmers’ profitability.

  4. CT assessment of progression in pulmonary emphysema

    The purpose of this study was to assess the progression of pulmonary emphysema (PE) using CT. We reviewed the records of 25 cases (all male smokers and age range of 36-85 years) in whom progression of PE was recognized using CT scanning. PE was diagnosed by the presence of low attenuation areas on CT scan. PE was divided into 2 subtypes: centrilobular emphysema (CLE) and paraseptal emphysema (PSE). There were 8 younger cases less than 50s. With respect to smoking habit, 6 cases had 1 pack per day at maximum whereas the remaining 19 cases had more over than 1.5 packs per day. Interval periods of observation were from 8 months minimum to 10 years maximum. PE, of both CLE and PSE subtype, was recognized even in younger cases less than 40 years of age, and progressed with cigarette consumption even a minimum during 8 months periods of observation.

    2010-12-01

    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.

    2011-06-01

    A total of 286 individuals from 3 selected communities (Areedi-Aje, Ipakodo/Ojokodo, and Ijebu-Igbo) of Ijebu-North, southwestern Nigeria were examined for Loa loa microfilaremia using finger prick blood smear, between December 2008 and March 2009. Rapid assessment procedure for loiasis (RAPLOA) was used to obtain information, from 187 Ijebu-Igbo residents, on adverse reactions experienced from retrospective treatments with ivermectin and history of eye worm. Only 33.9% of the respondents reported having had a history of eye worm while 33.2% had microfilaremia. The demographic factor of gender was not significant determinants of the prevalence (P>0.05) while age was significant (PIgbo had 27.3% eye worm history, 32.1% microfilaremia, and the highest intensity of 140 microfilariae (mf)/ml. Ipakodo area had the highest eye worm history of 54.4% and the highest intensity of 420 mf/ml. Areedi-Aje had the highest occurrence of 45.2% microfilaremia and the highest intensity of 460 mf/ml. Predictably, Areedi-Aje and Ipakodo areas were high risk communities. The low intensity of L. loa infection with an insignificant (2.1%; P>0.05) adverse reactions from 187 subjects involved in the retrospective ivermectin administration confirmed that ivermectin delivery may be considered safe. The community-directed treatment with ivermectin (CDTI) programme was most probably responsible for the low prevalence and intensity. PMID:21738271

    Full Text Available The study assessed the quality of groundwater of 6 inland valley (IV agro-ecosystems with a view to establishing their characteristics for cropping in the derived savannah of southwest Nigeria. Water samples were collected in piezometers during the rainy and dry seasons and analysed for physicochemical and heavy metal properties. Major water quality indices and comparison with stipulated standards were used to determine the usability of the waters for irrigation. The study showed that the waters were generally neutral to slightly alkaline, with the dominance structure of the major cations and anions in the order of Na+ > Ca2+ > K+ > Mg2+ and Cl- > SO42- > HCO3- > CO3. The concentration of heavy metals was generally within the recommended limits for most crops grown in the study area. Major water quality indices (sodium adsorption ratio, soluble sodium percentage, total dissolved solids, permeability index, magnesium adsorption ratio, Kelly’s ratio and residual sodium bicarbonate are generally within the levels acceptable for crop irrigation. Kruskal-Wallis H test (two-tailed showed that there was no statistically significant difference in the water quality parameters/indices between the inland valley sites, P = 0.935. The groundwater of inland valley agro-ecosystems of the study area is generally suitable for agricultural utilisation.DOI: http://dx.doi.org/10.5755/j01.erem.71.2.10802

    2016-04-01

    Full Text Available The study assessed risk in the Internally Generated Revenue structure of Abia State, Nigeria. The specific objectives included (I estimation of factors and significant input variables influencing risk in IGR structure of the State and (II examination of risk reducing practices. Data which were collected from 50 management staffs of revenue yielding Ministries, departments and agencies in Abia State were analysed with factor analysis, Tobit regression analysis and descriptive statistics. The results of the factor analysis grouped the significant input variables which scored 0.33 and above into institutional and non-institutional sources of risk while that of Tobit regression analysis revealed that significant variables which cause variation between expected and realised IGR of the State are lack of database; mismanagement of fund by government; delay in payment of revenue by tax payers; difficulty in tracking tax evaders; and weak internal control mechanism. The results point to the fact that policy on tax identification number (TIN should be strengthened and linked to the bank account of the tax payer so that relevant revenues are deducted at source.

    2012-03-01

    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.

    Omoniyi Matthew Isinkaye

    2015-01-01

    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 The use of the Internet can further equip teachers by providing them with the latest information on their discipline. 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.

  14. Assessment of Groundwater Quality in a Typical Rural Settlement in Southwest Nigeria

    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.

    2015-11-01

    Full Text Available The study assessed factors influencing the participation of farmers in agroforestry system in Ekiti State, Nigeria. Data were collected from 157 sampled farmers with the aid of structured questionnaire. Data were analysed using descriptive statistics and multiple regression model. The findings of the study revealed that the farmers were still in their agricultural active age group with average age of 46 years. Majority (42.7% of the respondents had tertiary education. The average land size cultivated by the farmer was 4.97 hectares. The results of farmers’ participation in agroforestry showed that more than half (52% of the farmers always practice agro-forestry system. The average score (2.34 obtained from Likert scale indicates that sampled farmers in the study area are practicing agroforestry system of farming. The socio-economic and institutional variables influencing rate of participation in agroforestry system were: level of education, size of farmland, membership of association, farming experience and extension contact. The study recommends that government should review the Land Act Decree and pay attention on land consolidation program in order to reduce land scarcity and fragmentation of farm holdings. This is because agroforestry farming requires large area of land.

    2014-09-01

    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.

    Mohammed Sirajo Aminu

    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.

  2. Assessment of the Adoption Rate of Technologies among Fadama III Farmers in Adamawa State, Nigeria

    Umar, AdamuMadu

    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.

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

    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

    2011-11-01

    Full Text Available Abstract Background Resilience seemed to lie at the core of the recent promotion of positive mental health and wellbeing. This concept has been well studied in western countries and less in developing countries, particularly Nigeria. The aim of the study is therefore, to demonstrate the internal consistency and concurrent validity of the Resilience Scale (RS and its 14-item short version (RS-14 in a Nigerian sample. Results The RS, RS-14, the Hospital Anxiety Depression Scale (HADS and two screening questions on experience of recent and upcoming distress were administered to 70 clinical students who consented to participate after a major professional examination. Internal consistency and convergent validity were assessed. The participants mean age was 22.50 years (SD = 0.60. The mean score of RS and RS-14 were 130.23 (SD = 17.08 and 74.17 (SD = 10.14 respectively. Cronbach's alpha coefficient for the RS was 0.87 and that of the RS-14 was 0.81. The mean RS score by gender was 132.04 (SD = 19.08 and 126.52 (SD = 11.50 for males and females respectively and the difference was significant (t = 2.50; p = 0.012. The correlation of RS with RS-14 (r = 0.97; p = 0.000, the HADS depression (r = -0.28; p = 0.017 and anxiety (r = -0.26; p = 0.028 subscales, were significant. The corresponding t-test values for the means of RS and RS-14 scores for both cases and non-cases as determined by HADS, were significant at p Conclusions The study confirms that the RS and RS-14 may be potentially useful instruments to measure resilience in Nigerians.

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

    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

  6. Examining the influence of urban definition when assessing relative safety of drinking-water in Nigeria

    Reducing inequalities is a priority from a human rights perspective and in water and public health initiatives. There are periodic calls for differential national and global standards for rural and urban areas, often justified by the suggestion that, for a given water source type, safety is worse in urban areas. For instance, initially proposed post-2015 water targets included classifying urban but not rural protected dug wells as unimproved. The objectives of this study were to: (i) examine the influence of urban extent definition on water safety in Nigeria, (ii) compare the frequency of thermotolerant coliform (TTC) contamination and prevalence of sanitary risks between rural and urban water sources of a given type and (iii) investigate differences in exposure to contaminated drinking-water in rural and urban areas. We use spatially referenced data from a Nigerian national randomized sample survey of five improved water source types to assess the extent of any disparities in urban–rural safety. We combined the survey data on TTC and sanitary risk with map layers depicting urban versus rural areas according to eight urban definitions. When examining water safety separately for each improved source type, we found no significant urban–rural differences in TTC contamination and sanitary risk for groundwater sources (boreholes and protected dug wells) and inconclusive findings for piped water and stored water. However, when improved and unimproved source types were combined, TTC contamination was 1.6 to 2.3 times more likely in rural compared to urban water sources depending on the urban definition. Our results suggest that different targets for urban and rural water safety are not justified and that rural dwellers are more exposed to unsafe water than urban dwellers. Additionally, urban–rural analyses should assess multiple definitions or indicators of urban to assess robustness of findings and to characterize a gradient that disaggregates the urban

    Full Text Available Background: In line with the recommendation of artemisininbased combination therapy (ACT by WHO in the effective treatment of uncomplicated malaria, African nations including Nigeria changed their malaria treatment policy to combination therapies. To date, about 15 African nations adopted artesunate /amodiaquine (AA as their first line agent while Nigeria adopted artemether /lumefantrine (AL. Objective: The objective of this study is to compare the treatment outcome among patients treated with AA to those treated with AL for acute uncomplicated malaria. Method: The study was conducted at Nnamdi Azikiwe University campuses using quantitative methods. Two hundered and ninety six patients were randomly allocated to one of two treatment group- AA and AL with 148 patients per group. All the patients were educated about the drugs and adherence. Adherence and treatment outcomes including parasite clearance and the drugs’ effects on biochemical parameters among others were assessed by follow up visits on third, seventh, fourteenth and twenty eighth-day post treatment. Data were analysed using Cox Regression model on SPSS 17.0. Result: Both drugs were well adhered to and tolerated. One case of Steven Johnson-like reaction was observed with AL. Fever resolution and parasite clearance was similar in both groups with adequate clinical and parasitological response (ACPR by day 28 for AL and AA being 70.3% and 85.1% respectively. Conclusion: Our findings is in favour of higher efficacy of AA with respect to their ACPR. More controlled studies will be needed to ascertain the adoption of AL as first line drug in malaria treatment in Nigeria.

  14. Assessment of the level of male involvement in safe motherhood in southern Nigeria.

    Nwakwuo, Geoffrey Chima; Oshonwoh, Ferdinand Ebiarede

    2013-04-01

    Pregnancy and the events surrounding it are generally viewed as feminine issues exclusively for women. In sub-Saharan Africa, believing that pregnancy and the events that follow are guided by nature, a lot of superstition is attributed in the event of complications, which result in poor maternal outcomes. Maternal mortality remains a public health challenge worldwide, and Nigeria has one of the highest levels of maternal mortality in the world (545 per 100,000 live births). The involvement of men in ensuring and enhancing maternal health was a great idea hatched at the Cairo conference in 1994, but since then, not much has been done in practical terms in most of the developing world. This study is aimed at assessing the level of male involvement in their spouses' reproductive health events before pregnancy, during pregnancy, delivery and peuperium. A descriptive cross-sectional study design in which questionnaires were incorporated with an in-depth interview was used and a multistage sampling technique was used to select respondents. After house numbering, a total of 400 houses were selected from a cluster of four quarters in Patani Town. Participants were systematically sampled from each household using random number table. Results from data collected on the study indicated that (61.1 %) of men were aware of maternal health issues and the level of education was shown to have significant relationship (χ² = 5.139, df = 3, p = 0.162) with the knowledge of maternal health issues. Though the level of male involvement in safe motherhood was shown to be of good proportion, strategies to create awareness on male support for their parous spouses should be given a broader frontier, both in clinics, household and community levels. Men should be more involved than before, as they have a priceless role to play towards a significant improvement in maternal health. The Government, development partners and NGOs at all levels should be committed with a strong political

  15. Water quality assessment of the Asata River catchment area in Enugu Metropolis, Southeast Nigeria

    Osinowo, Olawale Olakunle

    2016-09-01

    Hydrogeochemical mapping of the Asata River Catchment area in the Enugu metropolis, southeast Nigeria was carried out in order to assess the quality of the surface and groundwater and based on the analyses of the hydrogeochemical data, establish the level of chemical contaminations which inhibit the availability of potable water in the area. Forty (40) water samples comprising five (5) springs, nineteen (19) surface (streams/rivers) and sixteen (16) groundwater (well/borehole) samples were collected and analysed for the presence and degree of contamination of nine (9) major chemical contaminants. Hydrochemical analyses indicate that Electrical Conductivity (EC) which has a linear relationship with Total Dissolved Solid (TDS) ranges between 015 and 887 μS/cm, pH between 4.4 and 8.3, nitrate (NO3-) ranges between 40 and 130 mg/l and chloride (Cl-) between 7 and 130 mg/l. The concentrations of the dissolved chemical constituents defined the pollution trend and the rate of dispersion of contaminants. The degree of contaminants followed a simple trend, where the level of contamination of the dissolved chemical constituents is least in sampled spring water, with measured chemical constituents of EC, pH, NO3- and Cl- range from 15 to 354 μS/cm; 6.4-6.5; 4.0-70 mg/l and 8-36 mg/l, respectively. However, the value of the measured chemical constituent of EC, pH, NO3- and Cl- gradually increases down the stream in both the surface (63-354 μS/cm; 4.5-7.7; 7.1-110 mg/l; 8-41 mg/l) and groundwater (56-531 μS/cm; 4.5-7.5; 40-130 mg/l; 7-130 mg/l), respectively. Noticeable peaks in contamination levels characterised sections of the study area where human population or their activities is highest. The result of the hydrogeochemical mapping indicate that Enugu coal mine operation, the industrial activities, fertilizer applied to plants cultivated on river banks and domestic human wastes which are indiscriminately dumped along river channels are the major sources of chemical

    2013-11-01

    Full Text Available A number of research studies have been carried out on the causes and effects of variation on construction project delivery, thereby taking for granted the susceptibility of building elements to variations. This formed the basis of this paper with a view to assessing the cost and time implications of the susceptibility of each building element to variation during construction process in Nigeria. Archival record comprises contract drawings, original bill of quantities, addendum and reduction bill of quantities, and minutes of site meetings among others were used to extract data relating to initial cost, final construction cost, estimated period, final completion period of each building element attributed to variations. The data obtained were analyzed using statistical methods of average, percentage, regression analysis, and analysis of variance (ANOVA. The study identified the building elements having greater than 20% of cost overrun due to variation as earthwork and fillings, frame, windows and external doors, fittings and furnishings, water installation, and external services. The study further identified the building elements having greater than 25% time overrun due to variation as earthwork and fillings, block work (at substructure, upper floors, external walls, wall finishing among others. The results of ANOVA and regression analysis on the building elements cost and time were used to establish models. Thus, the established models are: AFC= 981690 + 1.033AIC; and AFCO= 608390.865 +1.310AIC to predict the average final cost of each building element, and the average final cost overrun of each building element due to variation respectively, where AFC= Average Final Cost, AIC= Average Initial Cost, and AFCO= Average Final Cost Overrun. Also, the study established the model: Y = 1.379(X – 0.251 for predicting the average actual completion period of each building element, where Y= Average Actual Completion Period, and X= Average Estimated Period

  5. Possible impact of climate change on meningitis in northwest Nigeria: an assessment using CMIP5 climate model simulations

    Abdussalam, Auwal; Monaghan, Andrew; Steinhoff, Daniel; Dukic, Vanja; Hayden, Mary; Hopson, Thomas; Thornes, John; Leckebusch, Gregor

    2014-05-01

    Meningitis remains a major health burden throughout Sahelian Africa, especially in heavily-populated northwest Nigeria. Cases exhibit strong sensitivity to intra- and inter-annual climate variability, peaking during the hot and dry boreal spring months, raising concern that future climate change may increase the incidence of meningitis in the region. The impact of future climate change on meningitis risk in northwest Nigeria is assessed by forcing an empirical model of meningitis with monthly simulations from an ensemble of thirteen statistically downscaled global climate model projections from the Coupled Model Intercomparison Experiment Phase 5 (CMIP5) for RCPs 2.6, 6.0 and 8.5 scenarios. The results suggest future temperature increases due to climate change has the potential to significantly increase meningitis cases in both the early and late 21st century, and to increase the length of the meningitis season in the late century. March cases may increase from 23 per 100,000 people for present day (1990-2005), to 29-30 per 100,000 (p<0.01) in the early century (2020-2035) and 31-42 per 100,000 (p<0.01) in the late century (2060-2075), the range being dependent on the emissions scenario. It is noteworthy that these results represent the climatological potential for increased cases due to climate change, as we assume current prevention and treatment strategies remain similar in the future.

    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.

    2013-07-01

    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.

  9. High-potential geothermal energy resource areas of Nigeria and their geologic and geophysical assessment

    Babalola, O.O.

    1984-04-01

    The widespread occurrence of geothermal manifestations in Nigeria is significant because the wide applicability and relative ease of exploitation of geothermal energy is of vital importance to an industrializing nation like Nigeria. There are two known geothermal resource areas (KGRAs) in Nigeria: the Ikogosi Warm Springs of Ondo State and the Wikki Warm Springs of Bauchi State. These surficial effusions result from the circulation of water to great depths through faults in the basement complex rocks of the area. Within sedimentary areas, high geothermal gradient trends are identified in the Lagos subbasin, the Okitipupa ridge, the Auchi-Agbede are of the Benin flank/hinge line, and the Abakaliki anticlinorium. The deeper Cretaceous and Tertiary sequences of the Niger delta are geopressured geothermal horizons. In the Benue foldbelt, extending from the Abalaliki anticlinorium to the Keana anticline and the Zambuk ridge, several magmatic intrusions emplaced during the Late Cretaceous line the axis of the Benue trough. Positive Bouguer gravity anomalies also parallel this trough and are interpreted to indicate shallow mantle. Parts of this belt and the Ikom, the Jos plateau, Bauchi plateau, and the Adamawa areas, experienced Cenozoic volcanism and magmatism.

    2012-02-01

    Full Text Available A study to assess the trace element chemistry in the vicinity of a recently established aluminium smelting complex in Ikot Abasi, south-eastern Nigeria was carried out, using stream sediments as sampling media. Twenty three trace elements; Ag, Cu, Mn, Mo, Ni, Pb, Zn, As, B, Bi, Co, Cr, Ga, La, Sb, Sc, Sr, Th, V, W, Y and Zr, were analysed for in the sediments. Results from analyses showed that concentration levels of these elements were within limits of geogenic sourcing. Correlation and factor analyses indicated associations of chemical species to be related to the adjoining geologic suites; Precambrian basement and Cretaceous sediments. Comparatively the sediments exhibit geochemical characteristics consistent with sediments from other parts of the Niger Delta. The deductions provide a baseline data set for future monitoring around the smelting site.

    Full Text Available Introduction: Tuberculosis (TB data are used to evaluate the effectiveness of TB program interventions, identify deficiencies, and inform policies and programs. These data are also used for advocacy, resource mobilization, and allocation, both nationally and internationally. This study is aimed at verifying the reliability of the data collated and submitted from the direct observation therapy strategy (DOTS facilities to the National TB Program (NTP in some selected states in Southern Nigeria. Materials and Methods: A total of 29 facilities providing TB services were purposively selected from six states in Southern Nigeria, based on the treatment success rate as reported in 2009. In each selected facility, the following records were reviewed for concordance: Patient treatment cards and facility TB register, facility TB register and facility laboratory register, facility TB register and local government area (LGA TB register, and LGA TB register and TB quarterly reports. Furthermore, a total of 273 patients were selected for interview to validate the information contained in the treatment cards. Results: Agreement between the data sources was relatively high, though higher in some states than the others. Agreement between patient treatment card and facility TB register, and facility TB register and laboratory register were 97% and 85%, respectively. The lowest concordance was observed between the facility TB register and the LGA TB register. All the patients interviewed confirmed the information as recorded in their treatment cards. Conclusion: The study revealed that NTP data in Southern Nigeria is fairly reliable; however, there are variations observed among the states and at various levels. This study underlines the need to improve TB surveillance data in some states, particularly at the facility and at the LGA levels.

    2013-09-01

    Full Text Available Nigeria is a major importer of rice in the world with over 756 million USD annual expenditure on rice importation. This is probably due to insufficient domestic production occasioned by inefficient utilization of resources and other farm inputs. This study is therefore designed to estimate the costs and returns to rice production; and analyze resource use efficiency in rice production in Ogun State, Nigeria. A three-stage sampling technique was used to select a total of 120 rice farmers. Gross margin and regression analyses were used to analyse the data for the study. The study revealed that an average small scale rice farmer realizes a gross margin of N 90, 634.35 per hectare. While farm size, labour and crop production systems account for 80.5% (coefficient of multiple determination, R2 of the changes in rice production, the study revealed that farm size, labour and seeds were grossly underutilized in rice production. The study therefore recommends the need for policy that would enhance increase in the allocation of land, seeds and labour in the production of rice.

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

    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.

    Abdulazeez, Muhammad-Lawal

    2014-06-01

    Full Text Available The study carried out an assessment of agricultural land management practices in food crops production among small scale farmers in Kwara Sate, Nigeria. Specifically, the study determined the socio economic characteristics of crop farmers in Kwara State; ascertained the cropping patterns common among them; highlighted the soil conservation methods adopted by the farmers; examined the relationship between selected socio-economic characteristics of the farmers and their adoption of major agricultural land management practices; and investigated the constraints to adoption of sustainable agricultural practices among crop farmers in Kwara State, Nigeria A three stage random sampling technique was used in selecting a total of one hundred and forty four small scale food crops farmers. Descriptive statistics, binary logistic regression model and four point Likert-type scale were used to analyse the data for the study. The study revealed that food crops production in Kwara State is dominated by middle aged men who are poorly educated and have poor access to agricultural extension services. Half of the respondents (48.60% adopted cereal-based cropping systems. 48.6% of the farmers adopted a minimum of three management practices. Crop rotation was mostly adopted by all the farmers while irrigation was the least adopted by only 29.3% of the respondents. Furthermore, the study revealed that farm size, age, education status, number of contacts with extension agents, household size and number of farm plots of the respondents were the significant factors affecting their adoption of land management practices. The study also revealed that the major constraints to the use of sustainable crop management practices among the farmers included inadequate supply of fertilizer, inadequacy of labour and credit, poor knowledge of improved agricultural practices, poor transportation, low produce prices and high cost of production. The study recommended the need for training

    OSUJI, U. S. A

    2010-10-01

    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.

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

  19. Microburst windspeed potential assessment: progress and developments

    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 ...

    Full Text Available The study examined the perception of benefits of organic gardening in Maiduguri Metropolis, Nigeria. Structured questionnaires were administered to obtain information from 166 respondents through multi-stage random and purposive sampling techniques. Data collected were analysed using descriptive statistics (frequency distribution, percentage and mean scores. The study indicates that the respondents had perceived a relatively neutral (mean score = 2.87 socio-economic benefits of organic gardening. Nevertheless, they agreed (mean score = 3.84 with the ecological benefits or organic farming. The result, equally reports that the intension of conversion to organic farming was relatively neutral (mean score = 3.49. The most important constraint to organic gardening conversion was lack of knowledge and skills regarding organic gardening. Policy recommendations were made to include: the creation of awareness on the consequences of synthetic fertilizers, pesticides among others, and adequate government support for organic gardening in the study area.

    Full Text Available The study examines the marketing of frozen fish in Edo State of Nigeria. The primary data used for the study were derived using structured questionnaires administered to 180 randomly selected frozen fish marketers from six markets. Both descriptive and inferential statistics were used in data analysis. From the findings, marketing of fish is mainly carried out by females, most of the respondents are in the economically active age group and are mostly married; they have a lot of experience in the business, majority of them are retailers selling less than four cartons of fish on daily basis and most of them have formal education. From the gross margin analysis and t-test, marketing of frozen fish is profitable in the area. However, it was recommended that major constraints like poor storage/preservation, inadequate capital and marketing costs should be tackled to improve the efficiency of marketing system of frozen fish in the State.

    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%.

    2011-08-01

    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.

  5. Are patent medicine vendors effective agents in malaria control? Using lot quality assurance sampling to assess quality of practice in Jigawa, Nigeria.

    Sima Berendes

    Full Text Available BACKGROUND: Patent medicine vendors (PMV provide antimalarial treatment and care throughout Sub-Saharan Africa, and can play an important role in the fight against malaria. Their close-to-client infrastructure could enable lifesaving artemisinin-based combination therapy (ACT to reach patients in time. However, systematic assessments of drug sellers' performance quality are crucial if their role is to be managed within the health system. Lot quality assurance sampling (LQAS could be an efficient method to monitor and evaluate PMV practice, but has so far never been used for this purpose. METHODS: In support of the Nigeria Malaria Booster Program we assessed PMV practices in three Senatorial Districts (SDs of Jigawa, Nigeria. A two-stage LQAS assessed whether at least 80% of PMV stores in SDs used national treatment guidelines. Acceptable sampling errors were set in consultation with government officials (alpha and beta <0.10. The hypergeometric formula determined sample sizes and cut-off values for SDs. A structured assessment tool identified high and low performing SDs for quality of care indicators. FINDINGS: Drug vendors performed poorly in all SDs of Jigawa for all indicators. For example, all SDs failed for stocking and selling first-line antimalarials. PMV sold no longer recommended antimalarials, such as Chloroquine, Sulfadoxine-Pyrimethamine and oral Artesunate monotherapy. Most PMV were ignorant of and lacked training about new treatment guidelines that had endorsed ACTs as first-line treatment for uncomplicated malaria. CONCLUSION: There is urgent need to regularly monitor and improve the availability and quality of malaria treatment provided by medicine sellers in Nigeria; the irrational use of antimalarials in the ACT era revealed in this study bears a high risk of economic loss, death and development of drug resistance. LQAS has been shown to be a suitable method for monitoring malaria-related indicators among PMV, and should be

  7. Research progress in dynamic security assessment

    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.

    2015-12-01

    Full Text Available In recent times, many zoonotic diseases have emerged with serious negative consequences on humans. In the light of this, ante-mortem inspections were conducted, using body condition scoring to assess the health status of livestock presenting for slaughter, and to identify issues relating to meat inspection in four purposively selected government approved abattoirs in Benue State, Nigeria. The result of our assessment showed that 5.0% of the cattle and goats presented for slaughter during the investigation period were highly emaciated animals with a prevalence range of 0.0–12.1% with variance between abattoirs, whereas 37.9% were moderately emaciated and 57.2% had good body condition. Extreme emaciation was higher in cattle (6.7% compared to the goats (3.2%. The moderately high prevalence of emaciated animals intended for human consumption coupled with unorganized and inappropriate meat inspection in the studied abattoirs has serious public health implications. To prevent consumers from contacting zoonotic diseases, education of butchers and traders is necessary for thorough and effective inspections. In addition, animal traders should be encouraged to seek veterinary assistance for their sick animals. Meat inspectors should treat all emaciated animals as suspects, as emaciation could be a cause from underlying health problems.

  10. An Assessment of Nigerian Stakeholders’ the Perception of Environmental Offset as Mitigation Measures and Its’ Implication for Sustainable Industrial Development in Nigeria

    P.C. Mmom

    2011-07-01

    Full Text Available An important tool for sustainable development in any country is Environmental Impact Assessment (EIA, and an important component of EIA is impact mitigation. In most cases, certain unwanted impacts of development projects are left without mitigation thereby reducing the gains of such developments. Thus, emerging in current literature is the concept of Environmental offset which provides a leeway for residual impacts of development projects. This study therefore assesses the perception and level of application of the environmental offset strategy by EIA Practitioners and other stakeholders in the mitigation of negative environmental impacts of developments in the Niger Delta, Nigeria as that would have significant implication for sustainable development efforts in Nigeria. The study found out that there is negative perception among the host communities about the suitability of offset as mitigation measure. Even though the EIA practitioners considers Environmental offset as a viable option, its adoption has been marred by the misgiving of the local people. This misgiving could be attributed to the long period of neglect and abandonment which has led to abject poverty in the region and loss of confidence in any institutional frameworks. Thus, this study concludes that the drive towards sustainable Development in Nigeria would remain a mirage unless the local people are properly integrated in the scheme of things.

  11. Assessment of indoor radon concentration in phosphate fertilizer warehouses in Nigeria

    Indoor radon concentration level was measured in twelve selected phosphate fertilizer warehouses in Nigeria in order to establish potential hazards to persons using such warehouses as offices. The fertilizer warehouses were selected based on the brand of fertilizers stored, size, ventilation pattern and the number of workers in the warehouses during working hours. Electret Ion Chamber Technology (EIC) with the trade name E-PERMTM was employed for the measurement of radon concentration in the warehouses. Average radon concentration in the warehouses range between 33.6 Bq m−3 and 117 Bq m−3with an arithmetic mean of 91.62±5.9 Bq m−3. - Highlights: ► Indoor radon in phosphate fertilizer warehouses were measured using E-PERM monitor. ► The result shows that indoor radon varies from 36.6±4.9 to 117.0±8.78 Bq m−3. ► The average annual effective dose due to indoor radon in the warehouses is 0.87 mSv. ► This value is elevated though below the action level. ► Adequate ventilation is mandatory if phosphate fertilizer must be stored in offices.

    2013-08-01

    Full Text Available 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.

    T.A. Ayandiran

    2014-01-01

    Full Text Available Antibiotics are emerging environmental contaminants, causing both short-term and long-term alterations of natural microbial communities due to their high biological activities. The antibiotic resistance pattern of bacteria from anthropogenic polluted Oluwa River, Nigeria was carried out. Microbial profiling and antibiotic sensitivity tests were carried out on water and sediment samples using 13 different antibiotics. Microorganisms isolated include those in the genera Bacillus, Micrococcus, Pseudomonas, Streptococcus, Proteus and Staphylococcus. The microbial count of isolates from water samples ranged between 94.10 × 102 Cfu/100 ml and 156.20 × 102 Cfu/100 ml while that of sediment samples ranged from 2.55 × 104 Cfu g−1 to 14.30 × 104 Cfu g−1. From the water isolates, 100% resistance to antibiotics was found in Micrococcus spp. and Pseudomonas spp. while another Micrococcus, Streptococcus, Staphylococcus and Bacillus spp. showed between 40% and 90% resistances. From the sediment isolates, 100% resistance to antibiotics was found in a Bacillus spp. and Pseudomonas spp. while another Bacillus, Micrococcus, Staphylococcus, Streptococcus and Proteus spp. showed between 70% and 90% resistances. Multiple antibiotic resistance (MAR was shown by all the isolates and Bacillus, Micrococcus and Pseudomonas spp. showed the highest resistances (100% to all antibiotics. Thus, Oluwa River is not safe for public consumption.

    2014-01-01

    Full Text Available This study was conducted to analyze the perception of the rural woman about credit oriented self-help group in Delta State, Nigeria. A sample size of 110 respondents was used for the study and data were collected from them with the use of structured interview schedule and questionnaires. Data were analyzed using descriptive statistics and linear regression equation model as the lead equation. It was revealed that the women farmers subscribed to self-help groups in order to be able to have access to credit (mean = 3.78, information (mean = 3.55, extension services (mean = 3.45. 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.

  15. The Household Cooking Sector in Nigeria: Environmental and Economic Sustainability Assessment

    Haruna Gujba

    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.

    Full Text Available Beach tourism is a global phenomenon mainly in coastal areas of countries with unique and favorable shorelines. However, certain inland waterways serve same purpose of beach tourism. This research (as its objectives exposes the condition of amenities, identifies associated socio-economic benefits and reveals problems confronting the Lokoja Confluence Beach in Kogi State, Nigeria. A survey design (with the aid of questionnaires and interview guide was employed to obtain data from tourists, managers of the Confluence Beach and government officials at the State Tourism Board. Purposive sampling technique was adopted to select respondent tourists. Univariate analysis was employed to obtain relevant information from collated data. The research findings revealed the existence of a few functional amenities and some uncompleted facility projects; diverse economic benefits to residents; problems of petty crime, diversion of funds and poor sensitization. Recommendations include provision of supplementary funds by the three tiers of government, development of strategic policy on marketing/sensitization and provision of amenities for indoor games close to the beach front.

  17. Suitability assessment and mapping of Oyo State, Nigeria, for rice cultivation using GIS

    Ayoade, Modupe Alake

    2016-07-01

    Rice is one of the most preferred food crops in Nigeria. However, local rice production has declined with the oil boom of the 1970s causing demand to outstrip supply. Rice production can be increased through the integration of Geographic Information Systems (GIS) and crop-land suitability analysis and mapping. Based on the key predictor variables that determine rice yield mentioned in relevant literature, data on rainfall, temperature, relative humidity, slope, and soil of Oyo state were obtained. To develop rice suitability maps for the state, two MCE-GIS techniques, namely the Overlay approach and weighted linear combination (WLC), using fuzzy AHP were used and compared. A Boolean land use map derived from a landsat imagery was used in masking out areas currently unavailable for rice production. Both suitability maps were classified into four categories of very suitable, suitable, moderate, and fairly moderate. Although the maps differ slightly, the overlay and WLC (AHP) approach found most parts of Oyo state (51.79 and 82.9 % respectively) to be moderately suitable for rice production. However, in areas like Eruwa, Oyo, and Shaki, rainfall amount received needs to be supplemented by irrigation for increased rice yield.

  18. Assessment of antimicrobial drug residues in beef in Abuja, the Federal Capital Territory, Nigeria.

    Omeiza, Gabriel K; Ajayi, Itopa E; Ode, Okwoche J

    2012-01-01

    Drugs administered to food-producing animals close to the time of slaughter often result in prohibited antimicrobial residues in the animal tissues at slaughter. Evidence based on the Premi® test confirmed the occurrence of antimicrobial drug residues in 89.3% of kidney and urine samples from cattle slaughtered within Abuja town where the residents rely heavily on beef as a source of protein. The administration of antibiotics close to the time of slaughter by marketers/herd owners and transporters was found to be significantly (p<0.05) higher when compared with butchers and abattoir workers. The practice of administering antibiotics to animals close to the time of slaughter was believed to be profit-motivated. The research suggests that awareness campaigns amongst the stakeholders, the enactment of appropriate laws for the control of antibiotic use and the empowerment of veterinary public health practitioners in food regulatory agencies as some of the strategies which may positively reduce the risk of antimicrobial drug residues in food animals in Nigeria.

    Yohanna Irimiya,

    2013-10-01

    Full Text Available - The energy consumption end use of some selected residential buildings in Kaduna and Kano in the Northern part of Nigeria was studied by comparing their energy consumption pattern. The energy usage and intensities of the buildings as-built (Coventional and when retrofitted with green features were studied and the impact of the green retrofits documented. An Analysis of Variance (ANOVA was conducted at 0.05% which indicates a significant difference in the Energy consumption between the Conventional and Green features in the six study areas. From the study, the annual energy intensity of Kaduna for conventional buildings is 25.24 kwh/m2. With the introduction of green appliances, a drastic reduction in the buildings annual energy consumption was recorded which stood at 20.57 kwh/m2representing about 18.26% reduction in annual energy consumption which indicates a significant energy saving. In Kano VAC consumed the highest energy 12.49 kwh/m2of the total consumption of all end-users. When replaced with energy efficient appliances the consumption dropped to 7.95 kwh/m2representing 34.14% reduction. The use of energy efficient appliances is recommended.

    Full Text Available ABSTRACT The study examined coastal tourism potentials in Rivers State with emphasis on Opobo Bonny and Port Harcourt to determine the area that has comparative advantage for tourism development to optimally utilize resources. The study was conducted in Bonny Opobo and Port Harcourt of River State Nigeria. The area occupies the land close to the Atlantic Ocean within 60km radius from the coast. A survey design was adopted for the study. The instruments used were observation checklist and interview schedule. The instruments were tested for validity and reliability using five experts drawn from the field. The data collected were analyzed using ethnographic description method of analysis to answer research questions. The natural attractions found include mangrove forest sacred forests sacred rivers lakes beaches fishing rivers natural sources of drinking water and sanctuary. The cultural heritage resources were historical monument shrines museums different cultural festivals cultural materials and slave port. The man-made attractions were recreational park zoological garden and tourism village. It was found that there were more tourism potentials in Port Harcourt study site more than Bonny and Opobo sites and therefore Port Harcourt has comparative advantage over Bonny and Opobo for tourism development. Therefore efforts should be made and scarce resources utilized towards developing those coastal areas with best potentials and comparative advantage over others.

  1. Measurement of natural radionuclides and dose assessment of granites from Ondo State, Nigeria

    The activity concentrations of 226Ra, 232Th and 40K in fifty granite samples collected from five different quarry industries in Ondo State, Nigeria, were determined using gamma-ray spectrometry. The mean activity concentrations for each industry ranged from 16.7(6.4) to 85.4(23.0), 62.4(10.1) to 113.6(7.6), and 1315(136) to 1551(84) Bq.kg-1 for 226Ra, 232Th and 40K, respectively. The values in parenthesis are the standard deviations. When compared with results from some parts of the world, the 226Ra and 232Th contents were lower, whereas the 40K content was similar. Using different approaches to estimate the potential radiological hazard of the samples, the results obtained were below the recommended maximum limits. This shows that the radiological hazards associated with the use of the granites examined in this study as building material are within the acceptable limit. (authors)

    2008-01-01

    with general emphysema (general emphysema without phenotype PiZZ [non-PiZ] group) were scanned with CT at baseline and after 30 months. Densitometry was performed in 12 axial partitions of equal volumes. To indicate predominant location, craniocaudal locality was defined as the slope in the plot of densities......BACKGROUND: Lung densitometry is an effective method to assess overall progression of emphysema, but generally the location of the progression is not estimated. We hypothesized that progression of emphysema is the result of extension from affected areas toward less affected areas in the lung....... To test this hypothesis, a method was developed to assess emphysema severity at different levels in the lungs in order to estimate regional changes. METHODS: Fifty subjects with emphysema due to alpha(1)-antitrypsin deficiency (AATD) [AATD deficiency of phenotype PiZZ (PiZ) group] and 16 subjects...

    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

  6. Genetically significant dose assessments of occupationally exposed individuals involved in industrial and medical radiographic procedures in certain establishments in Nigeria

    The main source of radiation doses received by humans from man-made sources of ionizing radiation in medicine and industry comes from X-rays. The genetic risks of ionizing radiation effects on an individual who is occupationally exposed largely depend on the magnitude of the radiation dose received, period of practice, work load and radio logical procedures involved. In this work, using the linear non-thresh old model, we have attempted to assess the level of genetic risk of occupationally exposed individuals in two medical and industrial establishments in Nigeria by estimating their genetically significant dose values. The estimation was based on continuous personnel radiation dose monitoring data for the individuals in each of the establishments over a three year period (1998-2001). The estimated genetically significant dose values in the years considered were 12 mSv for the medical, and 29 mSv for the industrial personnel. Appropriate radiation protection precautions should be taken by the personnel to adhere to standard operational practices in order to minimize the genetically significant dose resulting from radio logical practices

    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 Background and Purpose: Several urban tree species are important in ethno-medicine, especially in the developing tropical regions. Their assessment in urban landscapes is becoming an important issue. The study assessed and mapped the ethno-medicinal trees in the built up area land use type of the University of Port Harcourt, Nigeria, with a view to examining their spatial variation in terms of composition and diversity between the residential and non-residential areas of the University Park. Materials and Methods: The study employed the use of geographic information system (ArcGIS 9.3 for the mapping. Built up area land use was subdivided into residential and non-residential where the ethno-medicinal trees were recorded, identified and enumerated. Global positioning system was used to determine the coordinates of each tree. The species composition and diversity were calculated and a comparison was made between the residential and non- residential land use types. The pattern of spread of the ethno-medicinal trees was determined by the nearest neighbour analysis. Results: A total of 37 ethno-medicinal trees species were found in the study area, while the species composition was 499 in the residential area and 438 in the non-residential area. Azadirachta indica was the highest (233 in composition. Ethno-medicinal tree species in the study area consist of 19 families of which Anacardiaceae, Rutaceae, Moraceae and Combretaceae were the highest. Species diversity was higher in the non-residential land use (2.698 than in the residential land use (2.222. Conclusion: The nearest neighbour analysis reveals that the z-score value was higher in the non-residential area (-23.06 than in the residential area (-0.30, but the pattern of distribution in both areas were clustered. The study recommended periodic monitoring and the assessment of ethno-medicinal trees in the study area for conservation purposes.

    Full Text Available An ecological impact assessment of crude-oil spills was carried out on the environment of an oil-rich community in the Niger Delta of Nigeria. Samples of the topsoil (0−15 cm, subsoil (15−25 cm and the dominant species Gamba grass (Andropogon gayanus were collected using the transect method from the point of spills. The samples were also collected from an unimpacted location (control. The samples were wet-digested and the concentrations of Pb, Cd, Cu, and Zn were determined by flame atomic absorption spectrophotometry, while the physico-chemical properties of the topsoil were determined by standard methods. The data were subjected to Student t test, ANOVA and Pearson correlation analysis, and the models for pollution assessment were employed to assess the pollution status of the soil and plant species. The results showed that concentrations of Pb, Cu and Zn in the topsoil exceeded international standards at close proximity to point of spills (0−200 m, while Cd concentrations exceeded the international standard at all the locations. Only Cd exceeded the international standard in the subsoil. Contamination (Pi and integrated pollution (Pc indices of the topsoil showed reducing trends from the point of pollution, and locations at 0 m and 100 m exhibited high Pc, while those at 200 m showed moderate Pc by all metals. The levels of Pb and Cd in the diagnostic species exceeded the World Health Organization limits and the pollution load index (PLI portrayed severe contamination. In conclusion, the impact of crude-oil spills in the area was significant; soil remediation is important to avert ecological and human health disasters. Moreover, these findings will be useful for designing strategic measures for environmental control in the area. DOI: http://dx.doi.org/10.5755/j01.erem.71.3.12474

  11. An Assessment of Records Management Practice in Selected Local Government Councils in Ogun State, Nigeria

    Bakare, Abdullahi A.

    2016-03-01

    Full Text Available What government does/fails to do is conveyed to the public largely by records and information of various types in the public service, without which there will be no government. When records are poorly managed, much time is involved in sorting and locating needed information from large volumes of records. The rate of records misplaced or lost from which useful information for decision making is usually obtained makes it difficult to provide concise and up-to-date records of both past and present operations, raising the challenge of effective record-keeping. Thus this study examined records management practices in selected local government councils in Ogun State, Nigeria, adopting the descriptive survey research method using questionnaires for data collection. Its population comprised 415 records of personnel in the selected councils, of which 208 were sampled using simple random technique. From the 208 copies of the questionnaire administered on the registry personnel, 150 copies were useable, with a 72.12% response rate. Descriptive statistics were used for the analysis. The results indicated a prevalence of paper as the dominant medium for recording/conveying information in the councils with most of these being either in active state, semi-active, and vital and were kept and maintained in the registry, while in-active records were kept in the records store. Storage facilities for record-keeping were insufficient. Security measures against unauthorized access to records were by restrictions and subject users to managerial clearance. The study concluded that council records were in chaos and recommended the formulation of coherent records management policy, adequate budgetary provision, and adequate finance.

    Full Text Available Objective. The study examines the personal health practices of small scale farmers in Kwara State, Nigeria. Materials and Methods. Primary data were obtained using a well-structured questionnaire which was distributed to 120 small scale farmers. Descriptive statistical techniques such as frequency count, percentages were used, as well as Pearson Product Moment correlation and analysis for empirical analysis. Results. Results revealed that more than half (55% smoke cigarettes, about 48% drink alcohol to a very great extent, while the majority (64.5% indicated they have not been screened to know their HIV status. On a positive note, the results further show that the majority 70%, 53.3%, 80% and 73.3% indicated that they eat a balance diet, engage in physical activity, practice safer sex, and regularly visit a health care centre, respectively. It also revealed that 77% have not attended any training on healthy living. The results of PPMC showed that the health knowledge of respondents had significant (p<0.01 influence on practices like cigarette smoking, eating a balance diet and regular visits to a health care centre. Conclusion. It was concluded that health threatening practices such as cigarette smoking and drinking alcohol among the majority of the respondents, coupled with their lack of health knowledge from health professionals, contributes to the poor health status of respondents which eventually negatively influences the labour efficiency of farmers. It is recommended that farmers should endeavour to make use of health literacy programmes introduced to them at local government level, and that the government should provide more of these health literacy programmes.

    Full Text Available Abstract Background Information about quality of malaria treatment services of different healthcare providers is needed to know how to improve the treatment of malaria since inappropriate service provision leads to increased burden of malaria. Hence, the study determined the technical and perceived quality of malaria treatment services of different types of providers in three urban and three rural areas in southeast Nigeria. Methods Questionnaire was used to interview randomly selected healthcare providers about the technical quality of their malaria treatment services. Exit polls were used to obtain information about perceived quality from consumers. A socio-economic status (SES index and comparison of data between urban and rural areas was used to examine socio-economic status and geographic differences in quality of services. Results The lowest technical quality of services was found from patent medicine dealers. Conversely, public and private hospitals as well as primary healthcare centres had the highest quality of services. Householders were least satisfied with quality of services of patent medicine dealers and pharmacy shops and were mostly satisfied with services rendered by public and private hospitals. The urbanites were more satisfied with the overall quality of services than the rural dwellers. Conclusion These findings provide areas for interventions to equitably improve the quality of malaria treatment services, especially for patent medicine dealers and pharmacy shops, that are two of the most common providers of malaria treatment especially with the current change of first line drugs from the relatively inexpensive drugs to the expensive artemisinin-based combination therapy, so as to decrease inappropriate drug prescribing, use, costs and resistance to artemisinin-based combination therapy.

    Yellow fever (YF) is a vector-borne disease affecting humans and non-human primates in tropical areas. In the past, there have been pockets of YF outbreaks in Nigeria that resulted in preventable deaths. Surveillance efforts towards avoiding another outbreak have been put in place with the aim of early detection and control. However, risk indices relating to the density of immature YF-mosquito vectors are given little consideration even though it is the first step in curbing a possible outbreak. Immature collections from 1538 houses in Ega, Oju, Otukpoicho and Otukpo in Benue State were carried out in 2010 and 2011. Risk indices such as house index (HI), container index (CI) and Breteau index (BI) were estimated. Molecular detection of YF was carried out on randomly selected Aedes larvae and pupae. Overall, 431,381 mosquitoes were collected in and around house premises. Thirteen species were identified: Ae. aegypti (Linneaus), Ae. africanus (Theobald), Ae. albopictus (Skuse), Ae. cumminsii (Theobald), Ae. luteocephalus (Newstead), Ae. simpsoni s.l. (Theobald), Ae. vittatus (Bigot), Anopheles gambiae Giles, An. nili (Theobald), Cx. nebulosus Theobald, Culex quinquefasciatus Say, Lutzia tigripes (Grandpre and Charmoy) and Toxorhynchites brevipalpis Theobald. The HI, CI and BI for Ae. aegypti were high in all the study locations, but low for Ae. lueteocephalus except in Ega. With 50 immature Aedes mosquitoes screened across locations, only Ae. aegypti from Ega were positive for YF. This study places Ega on a high alert of an impending YF outbreak. Thus, urgent steps to clear this area of potential mosquito sites are highly recommended. PMID:27189925

    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. PMID:20644686

    2016-07-01

    The subgrade soils in areas underlain by the slightly Migmatized to Non-migmatized Metasedimentary and Metaigneous rocks of Southwestern Nigeria have been considerably investigated. However, a serious research which employs electrical resistivity method for insight into the profile development, as well as estimation of resistance to deformation for predicting the stability of flexible highway pavements is yet to be carried out. In this study, Vertical Electrical Sounding (VES) were carried out after a reconnaissance survey based on stable and unstable locations on the road. Index and strength tests related to road construction were also carried out on bulk samples obtained from stable and failed (unstable) locations of the Ago-Iwoye/Ishara highway. Results show mostly three (3) layers in the profiles with H, HK, and HKH curve types. The subgrade soils below the stable locations have better vertical and interval variations in the resistivities (89-1095 Ωm) to a depth of 3.4 m as against those from the failed portions. Those from the stable locations also have higher specific gravity (2.72), low-medium plasticity and A-2-6 kaolinitic clayey soils with higher compacted density (2090 kg/m3) compared to subgrade soils from the failed locations. On the basis of Califonia Bearing Ratio (CBR), subgrade soils at stable locations have greater strength than those obtained from failed locations. Estimated resistance to deformation (R-value) and resilient modulus (MR) proved to be the overriding parameters for predicting the stability of the flexible highway pavements.

    2015-12-01

    Full Text Available Quality housing is the goal of all localities; such assurance reflects a community’s ability to respond to the needs of its citizens, as well as to accommodate growth and economic development. This paper focuses its study onhousing and neighbourhood quality condition in Ilesa, Nigeria.Data for the study were generated from both primary and secondary sources.204 households were surveyed using multi-stage sampling. Information was obtained on basic socioeconomic, housing and environmental characteristics of the respondent‘s household. The study reveals that more than half 54.3% of the respondents have open drainage in their neighbourhood, 33.8% have covered/buried drainage while the remaining 11.9% have soak away in their buildings. The finding reveals that 45.6% of the respondents are inherited occupier if their building, 34.4% of them is tenancy while the remaining 20.0% are owner occupier. However, positive and direct relationship exists between income and housing type (p = 0.000; r = 0.711, educational attainment (p = 0.000; r = 0.647 and type of toilet (p =0.000; r = 0.556. It was recommended among others that there should be activation in the senses embraces the emergence of citizens who will be aware of their environmental problems, who will believe changes are not only possible but feasible, and who will have a keen desire to change and accept changes.The paper therefore concludes that if the trend continues sustainable development in the area will remain unattainable.

  19. QUANTITATIVE ASSESSMENT OF METALS IN SOME ANTIPERSPIRANT FORMULATIONS MARKETED IN NIGERIA

    Kasim, L. S.

    2013-08-01

    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.

  20. Assessment of Rice Market Competiveness Using Horizontal Price Transmission: Empirical Evidence from Southern Region of Nigeria

    S. B. Akpan

    2016-06-01

    Full Text Available The study examined the horizontal price transmission and market integration between the local and foreign rice market in the Southern region of Nigeria. The study used average monthly prices of local and foreign rice in the rural and urban markets from January 2005 to June 2014. The findings show that, prices of local and foreign rice in the rural and urban markets have constant exponential growth rate of 0.60%. The Pearson correlation coefficient revealed a strong positive relationship between prices of local and foreign rice in both rural and urban markets. The cross-product Granger causality test revealed bidirectional relationship between prices of local and foreign rice in the region. The results of the cross co-integration test revealed the presence of co-integration between prices of the two products. The coefficients of the price variable in the cross co-integration equations for the local and foreign rice markets converge to the law of one price which connotes instantaneous price adjustment and competitiveness. The result of the cross - product error correction model also confirmed the existence of the short run market integration between the two markets. The study established the fact that, price of local rice competes favorably with its foreign counter part and thus a perfect substitute especially in the rural area. Based on the finding, it is recommended that, short term policies should be used to intervene in the rice sub sector in the region. Policies aimed at boosting local production of rice should be encouraged, while value additions in the domestic produced rice should be pursuit vigorously.

    Full Text Available The ecological and economic significance of creeks is of global importance to coastal areas. These advantages have been underutilized in many developing countries resulting in considerable pollution of its water ways. This study investigates the degree of pollution of the Ebute Meta creek system Lagos, southwestern Nigeria. Surface water, ground water, soil, sediment and plant samples were collected between the months of May and July 2011. Average surface water DO (2.39±1.45 mg/L, BOD (167±53 mg/L, COD (329±106 mg/L, NO3 - (28.3±3.67 mg/L, NH3 (22.3±4.8 mg/L and (Pb 0.23±0.02 mg/L levels indicated gross organic and metal pollution. Ground water similarly, showed elevated levels of BOD (12.9±0.7 mg/L, nitrate (36.1±5.35 mg/L and ammonia (13.7±2.6 mg/L. Metal levels in surface water and sediment was strongly correlated (r=0.89. Topsoil and vegetation samples around the vicinity of the creek did not show any significant level of contamination. There was no significant differences (p=0.05 in surface and ground water quality among the sampling points. The creek water was classified as heavily polluted. This could affect the aquatic flora and fauna of the creek ecosystem. Remediation measures should be employed to clean up the water way system and the environment.

    Objective:To investigate the quality of indoor air of different wards and units of Olabisi Onabanjo University Teaching Hospital, Sagamu, to ascertain their contribution to infection rate in the hospital. Methods: The microbial quality of indoor air of nine wards/units of Olabisi Onabanjo University Teaching Hospital, Sagamu, Nigeria was conducted. Sedimentation technique using open Petri-dishes containing different culture media was employed and samplings were done twice daily, one in the morning shortly after cleaning and before influx of people/patients into the wards/units and the other in the evening when a lot of activities would have taken place in these wards. Isolates were identified according to standard methods. Results: Results showed that there was a statistically significant difference (χ²=6.016 7) in the bacteria population of the different sampling time whereas it was not so for fungi population (χ²= 0.285 7). Male medical ward (MMW) and male surgical general (MSG) recorded the highest bacterial and fungal growth while the operating theatre (OT) was almost free of microbial burden. The bacteria isolates were Staphylococcus aureus, Klebsiella sp., Bacillus cereus, Bacillus subtilis, Streptococcus pyogenes and Serratia marscences while the fungi isolates included Aspergillus flavus, Penicillium sp., Fusarium sp., Candida albicans and Alternaria sp. Staphylococcus aureus was the predominantly isolated bacterium while Penicillium sp. was the most isolated fungus. Conclusions: Though most of the microbial isolates were potential and or opportunistic pathogens, there was no correlation between the isolates in this study and the surveillance report of nosocomial infection during the period of study, hence the contribution of the indoor air cannot be established. From the reduction noticed in the morning samples, stringent measures such as proper disinfection and regular cleaning, restriction of patient relatives’ movement in and out of the wards

    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.

    Contagious bovine pleuropneumonia is one of the most important trans-boundary disease affecting Fulani cattle herds of Nigeria and whose control is urgently needed. A Participatory Epidemiology approach and cross-sectional study were concurrently conducted to investigate qualitative and quantitative impacts of CBPP, respectively and associated socio-cultural factors that influenced exposure of Fulani nomadic pastoral communities to its risk in Niger State, North-central Nigeria between January and December 2013. A total of nine pastoral communities were purposively selected for qualitative impact assessment using Participatory Rural Appraisal tools, while 765 cattle randomly sampled from 125 purposively selected nomadic herds were analyzed using c-ELISA. Data on socio-cultural characteristics were collected using structured questionnaires administered on nomadic herd owners of the 125 selected herds. Kendall's Coefficient of Concordance W statistics and OpenEpi 2.3 were used for statistical analyses. Pastoralists' dependent factors associated with their socio-cultural activities were tested using Chisquare tests and likelihood backward logistic regressions. The mean proportional piles (relative qualitative impact) of CBPP was 12.6%, and nomads agreement on this impact was strong (W=0.6855) and statistically significant (Psource that caused concentration of stocks in one point was fifty three times more likely (OR 53.08; 95% CI: 14.91, 189.00) to be satisfactory practice that influenced occurrence of the disease in herds. This study highlighted the critical gap that exists in terms of significant influence of socio-cultural factors on CBPP occurrence in pastoral herds in Nigeria. Thus, CBPP surveillance, control and prevention programs that take these factors into consideration will be beneficial to the livestock industry in Nigeria, and indeed Africa. PMID:27237398

  5. Opportunities for Collaborative Adaptive Management Progress: Integrating Stakeholder Assessments into Progress Measurement

    Jim Berkley

    2013-12-01

    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.

    2013-04-01

    Full Text Available A microbiological assessment of soil polluted by refined petroleum was carried out in Eluama community, Isuikwuato LGA, Abia State, Nigeria between March and October, 2012. The aim of the study is to examine the long-term kinetics of refined petroleum oil contaminated soil in this area from pipeline vandalization in the year 2000 and to assess the extent of biodegradation with respect to length of time of the spill. The microbiological examination of the soil samples were conducted by serial diluting and then inoculating the soil samples on different growth media. Several microbiological and biochemical methods were applied in order to isolate and identify the microorganisms accustomed to the soil sample. An unpolluted farmland served as control. Results showed a decrease in microbial load of soil as distance approaches seepage area. The control has a total heterotrophic bacteria count of 22.3 x 106 CFU/ml which decreases towards the seepage area (4.1 x 106 CFU/ml. The total fungi count also decreases from the control (5.9 x 106 CFU/ml towards the seepage area (1.2 x 106 CFU/ml. Micococcus sp and Pseudomonas aeroginosa were predominant in the seepage area up to 30m away from the seepage area. Other bacteria identified after this distance include Bacillus sp, Klebsiella pneumonia, Streptomyces sp, Streptococcus sp and Staphylococcus aureus while the predominant fungi were Aspergillus niger and Mucor sp. The marked decrease of heterotrophic bacteria and fungi in the petroleum polluted area compared with the control (the unpolluted farmland shows the unsuitability of the soil for agricultural purpose, as full remediation has not taken place.

  8. Trends and Bioclimatic Assessment of Extreme Indices: Emerging Insights for Rainfall Derivative Crop Microinsurance in Central-West Nigeria

    Awolala, D. O.

    2015-12-01

    Scientific predictions have forecasted increasing economic losses by which farming households will be forced to consider new adaptation pathways to close the food gap and be income secure. Pro-poor adaptation planning decisions therefore must rely on location-specific details from systematic assessment of extreme climate indices to provide template for most suitable financial adaptation instruments. This paper examined critical loss point to water stress in maize production and risk-averse behaviour to extreme local climate in Central West Nigeria. Trends of extreme indices and bio-climatic assessment based on RClimDex for numerical weather predictions were carried out using a 3-decade time series daily observational climate data of the sub-humid region. The study reveals that the flowering and seed formation stage was identified as the most critical loss point when seed formation is a function of per unit soil water available for uptake. The sub-humid has a bi-modal rainfall pattern but faces longer dry spell with a fast disappearing mild climate measured by budyko evaporation of 80.1%. Radiation index of dryness of 1.394 confirms the region is rapidly becoming drier at an evaporation rate of 949 mm/year and rainfall deficit of 366 mm/year. Net primary production from rainfall is fast declining by 1634 g(DM)/m2/year. These conditions influenced by monthly rainfall uncertainties are associated with losses of standing crops because farmers are uncertain of rainfall probability distribution especially during most important vegetative stage. In a simulated warmer climate, an absolute dryness of months was observed compared with 4 dry months in a normal climate which explains triggers of food deficits and income losses. Positive coefficients of tropical nights (TR20), warm nights (TN90P) and warm days (TX90P), and the negative coefficient of cold days (TX10P) with time are significant at Prisk sharing framework.

  9. EMPIRICAL ASSESSMENT OF THE GROWTH RATE OF MAIZE PRODUCTION IN THE PRE - SAP, SAP AND POST - SAP PERIODS IN NIGERIA

    2012-05-01

    Full Text Available This study was carried out to provide empirical evidence on the growth rates of maize production in three sub - periods in Nigeria namely pre - Structural Adjustment Programme period, Structural Adjustment Program period and post - Structural Adjustment Programme period. Secondary data on maize production in Nigeria during the Pre - Structural Adjustment Programme period (1970 to 1985, Structural Adjustment period (1986 to 1994 and post - Structural Adjustment Programme period (1995 to 2007 were employed in this study. A growth rate model was used to estimate the growth rates of maize in the three sub - periods. The results of the analysis showed that the instantaneous growth rates of maize production are - 0.1%, 5.7% and 2.4% and the compound rates of growth of maize production are - 0.001%, 0.059% and 0.024% for the pre - Structural Adjustment Programme, Structural Adjustment Programme and post - Structural Adjustment Programme periods respectively. The higher compound growth rate of maize production in the Structural Adjustment Programme period implies that the policy reforms in the period was more effective in ensuring increased growth of maize production over that of other periods in Nigeria. Therefore, despite the myriads of problems associated with the programme in Nigeria, it was beneficial to maize production in Nigeria.

    2014-09-01

    Canine rabies is endemic and occurs throughout the year in all parts of Nigeria. A descriptive cross sectional study was designed to assess knowledge, attitude and practice of dog owners towards rabies, to check for the presence of rabies antigens in brain tissue of dogs slaughtered for human consumption and to assess rabies vaccination coverage of dogs in Wukari. Structured questionnaires were prepared and administered to 200 dog owners by face to face interview. The questionnaire sought information on demographic characteristics of the dog owners, their association with dogs, knowledge, attitude and practice of dog owners towards rabies. Associations between demographic variables and knowledge, attitude or practice scores were assessed using chi(2) analysis. Also, 188 brain samples from slaughtered dogs were analysed for presence of rabies antigen using direct fluorescent antibody test. Fifteen (7.89%) had rabies antigen. Record files and vaccination certificates of dogs presented to the State Veterinary Hospital Wukari were assessed for anti rabies vaccination coverage. Out of the 200 dog owners, only 26 (13%) knew that rabies virus can be found in nervous tissue, 121 (60.5%) were aware that rabies can be spread through the saliva of a rabid animal, but majority of respondents 172 (86%) did not know the age for first vaccination of dogs against rabies. Dog owners who were civil servants were 4.8 times more likely to have good knowledge (OR=4.84, 95% CI on OR 1.09-21.44) than those of other occupation groups. Positive attitude towards rabies increased with increase in age of dog owners, with respondents within the age group 20-30 years more likely to have negative attitude than those over 40 years. Civil servants were 9.8 times more likely to have good practice than other occupation groups. Rabies antigen was detected in 7.98% of slaughtered dogs. Out of 8370 dogs presented to the hospital between January 2003 and December 2012, only 1128 (13.50%) received anti

    2016-01-01

    Full Text Available Background: Galactorrhea is a common manifestation of hyperprolactinemia but may not always be present in women with hyperprolactinemia. This study was, therefore, undertaken to assess the serum prolactin levels of infertile women presenting with galactorrhea and to determine the prevalence of hyperprolactinemia among them. Materials and Methods: This was a retrospective study of serum prolactin levels of 63 female partners of infertile couples attending the gynecological clinic of Federal Medical Centre, Birnin Kudu, Jigawa State, Nigeria, who were found to have galactorrhea from January 1, 2012, to December 31, 2013. Ethical clearance was obtained. Solid phase enzyme-linked immunosorbent assay was used to measure serum prolactin. Sociodemographic characteristics were determined. The data obtained were analyzed using SPSS version 17.0 statistical software. Absolute numbers and simple percentages were used to describe categorical variables. Similarly, quantitative variables were described using measures of central tendency (mean, median and measures of dispersion (range, standard deviation as appropriate. Results: The average age of the women was 27.9 ± 5.6 years. In half of the cases (50%, galactorrhea was associated with menstrual disturbances, mainly amenorrhea (23.3%. Although most (63.3% of the clients had normal serum prolactin level despite being galactorrheic, averagely there was a marked elevation in serum prolactin of as high as 40.3 ± 52.3 ng/mL. Conclusion: We conclude, therefore, that the prevalence of hyperprolactinemia in this study was low when compared with other studies and that galactorrhea does not always indicate raised serum prolactin levels.

    2014-10-01

    Full Text Available Radiation exposures at the e-waste dumpsite around Alaba International Market, Lagos and three municipal waste dumpsites located in Ibadan and Ado Ekiti, southwest Nigeria were assessed by gamma ray spectroscopy using a highly shielded Canberra NaI (Tl detector. Soil samples were collected for analysis at the municipal waste dumpsites for comparison with e-waste dumpsite. Samples were also collected at a location free from waste dumps to serve as control. The mean concentrations of 40K, 226Ra, and 232Th obtained at the e-waste dumpsite were lower than those obtained at the municipal waste dumpsites and the controls site. The values obtained at the e-waste dumpsite were also lower than the world average values of 412 Bq/kg, 35 Bq/kg and 30 Bq/kg for 40K, 226Ra, and 232Th, respectively as reported by UNSCEAR. The mean annual effective dose rate obtained for the soil samples from e-waste dumpsite, Oritaperin, Ring-road and Ilokun dumpsites were respectively 0.026 mSv, 0.074 mSv, 0.080 mSv and 0.093 mSv/yr. The mean absorbed dose rate at the e-waste dumpsite was 21.12nGy/h which is lower than the world average of 60nGy/h. Values for other hazard indices were below the world average and lower than their respective minimum permissible limits. Hence, e-waste and municipal waste does not pose any immediate radiological risk to the people working/living in the vicinity of the dumpsites.

    2011-06-01

    Full Text Available The study assesses the spatio-temporal land use and land cover changes between 1986 and 2000 for the whole Obio/Akpor Local Government Area of Rivers State, Nigeria covering about 270.86 km2. Landsat images of 30 m × 30 m resolution of both 1986 and 2000 were used whereby seven land use types were detected and captured as polygons (shapefiles in Arcview 3.3 version after the images have been geo-rectified. The land use types include farmland, built up area, water, sparse vegetation, primary forest, secondary forest and mangrove. The area in square kilometers of each land use type in each year was calculated and thereafter the change was determined by subtracting the area of the same land use type in 1986 from 2000 and the percentage of change is therefore calculated. In addition, the probability of change of twenty years was also determined from one land use type to another using Markovian Transition Estimator (MTE from IDRISI Andes. The study reveals that farmland, mangrove, primary forest and sparse vegetation reduced over time by 45.34, 37.06, 43.06 and 8.09%, respectively while secondary forest, built up area and water increased by 5.88, 74.55 and 3.43%, respectively. It is also projected by MTE that in 2020 farmland has the probability of 0.570 (57% of changing to secondary forest and 0.154 (15.4% of changing to built up area. Primary forest has the probability of 0.186 (18.6% to change to built up area. It is recommended among others that laws should be promulgated to prevent unlawful expansion of construction of any form and that the people in the communities in the study area should be enlightened and educated on the effects of deforestation on the environment.

    2016-03-01

    Full Text Available Gender has been seen as an important factor in the distribution and utilization of productive resources worldwide. In the agricultural sector, gender differential could influence the sourcing and efficient utilization of factors of production, particularly in the livestock sub-sector of the economy. This study assessed the gender differentials in economic and technical efficiency of poultry eggs production in Lagos State, Nigeria. Multistage sampling technique was used to select respondent poultry farmers. The first and second stages were the purposive selection of five Local Government Areas (LGAs reputed for poultry production and farm settlements in the state. The third stage involved a simple random sampling of 150 poultry farms consisting of 75 farms each managed by a male and a female Stochastic Frontier Analysis (SFA. The SFA revealed that for male management of poultry egg farms, labour input (p<0.01 and cost of medications (p<0.05 increased the poultry egg output. On the other hand, for female management, stock of birds (p<0.01, labour input (p<0.01 and feed cost (p<0.01 were the factors that increased poultry eggs output. The inefficiency model revealed that male farmers were more technically efficient (p<0.01 than female counterparts. Female managed poultry farms had less productivity (0.90 compared to males(1.22. However, 88.1% of male farms compared to 86.7% of female farms had economic efficiency ratios between 0.29 and 0.79. The study concluded that gender had impact on poultry farmers’ efficiency in the study area. The study therefore recommended that training should be organised for female managed farms while male managed farms should utilize less of cost intensive capital input.

  17. Radioactivity concentrations and dose assessment for bitumen and soil samples around a bituminous deposit in Ondo State, Nigeria

    Bitumen samples and soil samples around a bituminous deposit in Ondo State, Nigeria, were analysed for 40K, 226Ra and 232Th employing gamma-ray spectrometry. The activity concentrations of 40K, 226Ra and 232Th in soil varied from (45.2 ± 5.3) to (484.2 ± 25.9), BDL (below detectable limit) to (27.7 ± 2.1) and (22.8 ± 2.7) to (62.4 ± 6.8) Bq.kg-1, respectively. The corresponding mean values were (240.2 ± 133.5), (13.3 ± 8.0) and (40.0 ± 10.2) Bq.kg-1, respectively. The mean activity concentrations of the radionuclides in the bitumen were (58.4 ± 36.4), (16.1 ± 13.3) and (32.5 ± 13.1) Bq.kg-1, respectively, for 40K, 226Ra and 232Th. The mean absorbed dose and effective dose for the soil samples were (41.5 ± 8.9) nGy.h-1 and (50.7 ± 10.9) μSv.y-1, respectively, while those of the bitumen samples were (29.5 ± 15.6) nGy.h-1 and (36.1 ± 19.1) μSv.y-1, respectively. For radiological hazard assessment, the radium equivalent activity and the external hazard index were determined. The values of the radium equivalent activity and external hazard index obtained for the soil and bitumen samples were lower than the recommended limit. (authors)

    2015-01-01

    Full Text Available This study assessed the indigenous methods of processing shea butter among women in Ilorin East Local Government Area of Kwara State, Nigeria. The study made use of well-structured questionnaire to collect data from 180 respondents by means of four-stage random sampling technique. Analytical tools used include frequency, percentage and Pearson product-moment correlation coefficient. Findings showed that the majority of respondents had no formal education (73.3%, were middle aged (52.2%, and married (81.1%. The indigenous processing techniques commonly used by the respondents include: picking/harvesting of fruits, washing of fruits, de-pulping, drying, seed selection, seed cracking, roasting of kernels, milling of kernels, boiling of ground kernels, kneading, mixing, filtration, solidification and packaging. The majority (75% of sources for information on indigenous shea butter processing came from family members. Factors limiting the majority of respondents were: inadequate water supply (95%, inadequate processing equipment (86.1% and inadequate credit facilities (81.7%. Correlation analysis results revealed that age (-0.153, p<0.05 and the years of experience (-0.270, p<0.01 of respondents showed a significant relationship with the indigenous techniques of processing shea butter. It was concluded that indigenous methods of processing shea butter are widespread among respondents, knowledge is acquired through family members and that they are faced with several challenges. Among others, the study recommends the need for extension agents to be posted to rural areas to educate rural women and build on their indigenous knowledge of processing shea butter in order to produce high quality butter.

  20. Assessment Of Heavy Metal Contamination Of Water Sources From Enyigba Pb-Zn District South Eastern Nigeria

    Nnabo Paulinus N

    2015-08-01

    Full Text Available Abstract A total of thirty 30 water samples were collected from the Enyigba PbZn mining district to assess the contamination of the water sources as a result of mining of lead and zinc minerals in the area. This comprises of 12 samples of surface water 14 from mine ponds and 4 from underground borehole water. The samples were acidified to stabilize the metals for periods more than four days without the use of refrigeration. The acidified water samples were analysed by a commercial laboratory at Projects Development Institute PRODA Enugu using Atomic Absorption Spectroscopy AAS. The elements determined by this method are lead Pb zinc Zn copper Cu arsenic As cadmium Cd nickel Ni manganese Mn and cobalt Co. The result and analysis of contamination factor showed that in surface water Cd had the highest concentration followed by As and Pb while Ni had the lowest. In mine ponds Cd also had the highest concentration and followed by Pb and As and Ni the lowest. In borehole water Cd has the highest concentration followed by Pb and As while Ni had the lowest concentration. Compared to WHO permissible limits the contamination of the heavy metals in all water sources are in order CdAsPbNiZnCu. In surface water the order is CdAsPbNiZnCu in mine ponds it is CdPbAsNiZnCu and in borehole water the order is CdAsPbZnNiCu. The calculated contamination factors show very high contamination status for Cd Pb and As. These levels of contamination and values indicate that under the prevailing conditions and environmental regulations in Nigeria the mining district would face major and hazardous discharges of these metals to the water sources.

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

    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

    Inam, Edu; Offiong, Nnanake-Abasi; Kang, Suil; Yang, Paul; Essien, Joseph

    2015-11-01

    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.

    Educational intervention programs are an important element to improve nurses' knowledge of pressure ulcer (PU) pre- vention. Various teaching methods have been used with diverse results but none have been analyzed in Nigeria. A quasi- experimental study using a pretest/post test design was conducted among 193 registered nurses with >6 months experi- ence who worked in purposefully selected wards (neuroscience, orthopedics, renal, and cardiac) in 3 teaching hospitals to examine the level of knowledge retention after interactive instruction. Participants were randomized to intervention (IG, n = 127 from 2 hospitals) and control (CG, n = 66 from 1 hospital) groups; the IG was provided a 5-day, face-to-face interactive lecture, and the CG engaged in a 1-day, 4-hour discussion of PU prevention practices. The Pressure Ulcer Knowledge Tool, a 47-item questionnaire in which a correct answer = 1 point and an incorrect/"I don't know" answer = 0 (maximum score 47), was used to assess and compare knowledge retention at 3 time points: baseline (T1), immediately after instruction (T2), and after 3 months (T3). Three trained research assistants assisted with registration of participants and distribution and collection of the questionnaires. All questionnaires were retrieved at T1 before the intervention be- gan. Respondents were encouraged to respond to all questions. Data were analyzed using t-test and ANOVA (P = 0.05). At T1, knowledge scores were comparable between the IG and CG (32.5 ± 4.2 and 30.8 ± 5.0 for IG and CG, respec- tively). At T2, knowledge scores increased significantly only in the IG to 40.7 ± 3.4 (d = 1.94, P less than 0.05). The mean difference between T1 and T2 was -8.2 ± 5.4, t = -17.0, P = 0.000. Similarly, mean scores increased significantly from T2 to T3 in the IG (mean= -2.0 ± 5.5, t = -4.1, P = 0.000); scores in the CG were -6.2 ± 7.2, t = -6.3 (P = 0.000). A face-to-face interactive lecture was shown to be an effective method of program delivery

    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

  12. Nigeria. Spotlight.

    Lecky, M

    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

    2015-07-01

    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, α = 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.

    2015-10-01

    Full Text Available Since the last few decades, spiritual formation has been receiving attention in theological education literature. An increasing number of theological educators have observed how easily this important objective of ministerial formation gets crowded out by the academic and ministry emphases. Others have called attention to the problem of fragmentation pointing to the need for integration in the work theological institutions do. Thus, it has become common to hear institutions boast of how integrated their programmes are and how much emphasis they place on spiritual formation. It is, however, not that common to see studies dedicated to finding out how these claims are actually realized in practice. The purpose of this paper is to assess to what extent Roman Catholic Seminaries in Nigeria comply with the emphasis in the Pastores Dabo Vobis (PDV on spiritual formation. The PDV is the dominant Roman Catholic document on ministerial formation since Vatican II. The PDV has been influential in highlighting the importance of spiritual formation in theological education globally. The paper gives a brief overview of the PDV’s portrayal of ministerial formation and then examines one Roman Catholic Seminary in Nigeria (the Claretian Institute, Nekede, Owerri  to see to what extent spiritual formation is carried out amongst other objectives. The paper concludes with salient lessons other theological institutions can learn from Claretian Institute’s effort at provision of holistic and relevant theological preparation for ministers.

    2015-12-01

    Full Text Available Adequate understanding of the extreme thermal condition is as important as that of the averages for planners and policy makers. A significant knowledge gap exists in the physiologic comfort in many developing countries, particularly in the tropical region where thermal stress can pose significant threat to life because of inadequate infrastructure. This study examines the hourly variations in the physiologic comfort of Nigeria using the effective temperature, temperature–humidity and relative strain indices (ETI, THI and RSI, respectively. It also examines the perceptions of a selected sample of Nigerians, and their coping strategies to extreme conditions of cold and heat stress. The results showed that physiologic comfort in Nigeria exhibits variations across the different latitudinal locations; shows seasonal variations and is affected by local geography. Perception of the comfortable climate exhibits variation based on the latitudinal location of the respondents but the coping strategies vary with the wealth of individuals. The study showed that physiologic discomfort is severe in many parts of Nigeria (especially in the climate regions outside the montane climate but the infrastructure to cope with the thermal stress is either poorly known or unaffordable for the majority of the people.

  18. Milestone-Based Assessments Are Superior to Likert-Type Assessments in Illustrating Trainee Progression

    Bartlett, Kathleen W.; Whicker, Shari A.; Bookman, Jack; Narayan, Aditee P.; Staples, Betty B.; Hering, Holly; McGann, Kathleen A.

    2015-01-01

    Background The Pediatrics Milestone Project uses behavioral anchors, narrative descriptions of observable behaviors, to describe learner progression through the Accreditation Council for Graduate Medical Education competencies. Starting June 2014, pediatrics programs were required to submit milestone reports for their trainees semiannually. Likert-type scale assessment tools were not designed to inform milestone reporting, creating a challenge for Clinical Competency Committees. Objective To determine if milestone-based assessments better stratify trainees by training level compared to Likert-type assessments. Methods We compared assessment results for 3 subcompetencies after changing from a 5-point Likert scale to milestone-based behavioral anchors in July 2013. Program leadership evaluated the new system by (1) comparing PGY-1 mean scores on Likert-type versus milestone-based assessments; and (2) comparing mean scores on the Likert-type versus milestone-based assessments across PGY levels. Results Mean scores for PGY-1 residents were significantly higher on the prior year's Likert-type assessments than milestone-based assessments for all 3 subcompetencies (P < .01). Stratification by PGY level was not observed with Likert-type assessments (eg, interpersonal and communication skills 1 [ICS1] mean score for PGY-1, 3.99 versus PGY-3, 3.98; P  =  .98). In contrast, milestone-based assessments demonstrated stratification by PGY level (eg, the ICS1 mean score was 3.06 for PGY-1, 3.83 for PGY-2, and 3.99 for PGY-3; P < .01 for PGY-1 versus PGY-3). Significantly different means by trainee level were noted across 21 subcompetencies on milestone-based assessments (P < .01 for PGY-1 versus PGY-3). Conclusions Initial results indicate milestone-based assessments stratify trainee performance by level better than Likert-type assessments. Average PGY-level scores from milestone-based assessments may ultimately provide guidance for determining whether trainees are

    2014-04-01

    Full Text Available This study assessed the radiological levels from Awwal artisanal gold mining exercises in Kebbi State. Results show mean values of activities of 40K>226Ra232 Th numerically as 425.96±5.56, 23.85±2.01 and 18.80±1.21 Bq/kg, respectively. The average outdoor gamma dose was 34.26 nGy/h while the mean annual effective dose rate was 42.15 &muSv/year (= 0.042 mSv/year, which is less than 0.07 mSv/year benchmark given in UNSCEAR (1993. Radio logically, the values obtained are low and do not imply any significant health concerns effects on the local population. However, the observed unprofessional practices such as lack of use of gas mask while working in the dust-filled mine cafes and at the mills could expose workers to possible risks from inhalation of respiratory crystalline silica as well as exposure to radon gas.

  1. Preliminary Assessment of Effects of Paint Industry Effluents on Local Groundwater Regime in Ibadan, Nigeria

    Olaoye, R. A.

    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.

    2012-04-01

    Full Text Available This study aimed at assessing the microbial colonizers, of apple fruits sold in Owerri to determine its safety for consumption. Apple fruits are dependable source of vitamins, it is rich in fiber, electrolytes, minerals and antioxidants and it is usually eaten fresh and raw, making the vitamins fully available for the body. The popularity and increased consumption of apple fruits therefore calls for necessary safety checks. Two hundred fresh and apparently healthy apple fruits were obtained from street vendors and shopping malls in major streets, motor parks and higher institutions in Owerri. The fruits were washed-out separately in 10 mL sterile distilled water to obtain suspensions which were assayed for total aerobic plate count, coliform count, and fungal count and for specific pathogens. A count of 3.4×105-4.5×107 cfu/mL was obtained for TAPC, while total coliform and total fungal counts ranges from 2.4×104-2.2×106 and 5.0×102-3.6×105 cfu/mL respectively. Twelve bacterial and seven fungal spp were isolated. The apple fruits sold in major busy spots in Owerri are contaminated, the presence of Shigella spp, S. aureus, Salmonella and B. cereus which are known pathogens calls for concern. Education of fruit vendors on food hygiene, adequate packaging/covering of apple fruits on display for sale and washing of fruits before consumption is advanced.

  3. A Quantitative Assessment of Surface Urban Heat Islands Using Satellite Multitemporal Data over Abeokuta, Nigeria

    K. A. Ishola

    2016-01-01

    Full Text Available The fast urban expansion has led to the transformation of the natural landscape into anthropogenic surfaces. The city of Abeokuta, for instance, is located in a region experiencing rapid urbanization, which has produced a remarkable effect on the surface thermal response. This effect significantly influences urban internal microclimatology on a regional scale. In this study, the surface temperatures and land cover types retrieved from Landsat TM and ETM+ images of Abeokuta city for 1984, 2003, and 2014 were analyzed. A quantitative approach was used to assess surface urban heat islands through the relationships among surface temperature and land cover types. Results showed that impervious surface areas were found to be correlated positively with high temperatures. Conversely, vegetated areas and bare surfaces correlated positively with mid temperature zones. This study found that areas with increasing impervious surfaces will accelerate LST rise and consequently lead to increasing effect of surface urban heat islands. These findings pose a major challenge to urban planners. However, the study would help to quantify the impacts of different scenarios (e.g., vegetation loss to accommodate urban growth on LST and consequently to devise appropriate policy measures.

    2010-05-01

    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 Formation damage canincurconsiderable cost for remediation and deferred production. Thorough understanding of the formation damage mechanisms, stringent measures for its control and prevention, and effective and efficient treatments are the keys for optimum production strategies for oil and gas fields. WELL 4X was investigated in this study to properly diagnosed and evaluate productivity in OREDO FIELD and Bottom Hole Pressure survey was used from Bottom Hole Pressure analysis in addition to the information of the well production history and reservoir data available to determine and assess the extent of the formation damage in the well. The WELL 4X was stimulated using Acid Foam Diversion Techniques to enhance reservoir productivity and increase economic operations. The stimulation job done on the well showed a peak increase of production from 850 bbl/day to 3200 b/d before it declined to 2150 bbl/day, and finally maintained an average stabilized rate of 2000 bbl/day. It has to be established that the treatment method on WELL 4X using Acid Foam Diversion Techniques and the Bottom Hole Pressure survey conducted on the WELL 4X in OREDO FIELD is found to be efficient in the determination and evaluation of formation damage.

    Full Text Available The study examined well water quality (chemical in Jos metropolis which it collected a total of twenty water samples that were taken for laboratory analysis. The stratified systematic random method was used in the selection of sample area/location. A total of (10 out of the existing (20 wards were systematically selected, while in each of the wards, two wells with one each from higher and lower elevations were randomly selected in which water samples were collected. The samples collected were analyses at UNICEF (WATSAN Laboratory Bauchi. USEPA method of water analysis was used to test for the chemical parameters. Pearson product moment correlation co-efficient was used test for the relationship between high and low elevation in the sample elements, as well as mean and standard deviation. The results indicates that pH, E.C, TDS, Pb, As and Cyanide appears within NSDWQMPL, while NO2, Cl, F, Mn, Mg, Ca, Cu, Zn, CaCo3 and Cr marginally falls within acceptable standard for drinking water quality maximum permitted limit. Consequently, NO3, SO4, Fe and CaCo3 in some parts of Jos metropolis fall outside acceptable standard of NSDWQMPL. Moreover, pH, E.C, TDS, Pb, NO2, NO3, Cl, F, Mn, Cr, As, Cu, Zn, showed that there is no significant relationship within the individual elements in regards to elevation (high and low in the study area whereas, SO4, Fe, Mg, Ca, CaCo 3 and CaCo3 showed that there is significant relationship in elevation (high and low among the individual sample elements. The study concludes that well water quality through chemical assessment in Jos metropolis is not fit for drinking. It recommends sensitizations campaign on the importance of clean water, sanitation, enforcement of existing laws and more research be undertaken to cover for seasonal variation, more elements and sample size.

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 Heavy-metal concentration levels in water, coal wastes, soil and background soil were determined with a view to assessing the degree of contamination and environmental impact due to coal mining activities around Onyeama coal mine. A total of 58 samples comprising 11 water, 11 coal wastes, 22 soils and 14 background soils were collected and analyzed. Various physico-chemical characteristics of water analyzed include pH, alkalinity, total hardness, total dissolved solids (TDS, sulphate, chloride, calcium and magnesium. Chemical analysis of water, coal wastes, soil and background soil samples were undertaken to determine concentrations of Cd, Cr, Ni, Cu, Co, Pb, Zn, As, Mn and Fe using an Atomic Absorption Spectrophotometer. The Enrichment Factor (EF and Pollution Index (PI results indicate significant enrichments of Cd, Pb and Ni in all the media examined compared with other elements studied. In water, the concentrations of Fe (3.13 mg/l, Cd (0.33 mg/l, Ni (1.30 mg/l, Cr (0.12 mg/l and As (0.07 mg/l exceeded the recommended values (1.0, 0.003, 0.02, 0.05 and 0.01mg/l respectively for potable water. In coal waste samples, Cd (2.52mg/kg is high with health risk level of 5. Cu (2.81mg/kg, Co (1.57 mg/kg and As (0.19 mg/kg moderately polluted the environment. In soil, high mean concentration levels are recorded for Cd (5.56 mg/kg and Pb (3.15 mg/kg, moderate to low levels for Cr (1.88 mg/kg, Cu (1.70 mg/kg, Co (0.44mg/kg, Mn (0.99mg/kg and As (0.16 mg/kg. Concentration of metals in the four media examined indicated that the level of pollution is in descending order as shown: soil medium >>>coal wastes medium >> water medium> background soil medium. Reference to World Health Organization standards, the observed trend in the concentration of the metals in the media, will pose health problems to humans and may impact adversely on the ecological, agricultural as well as underground water systems.

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

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

    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 112.53μSvy-1, 121.11μSvy-1 and 114.32μSvy-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

    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 μGyh-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 μGyh-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±8.14μSvy-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

  14. Assessing progress in the development of safety culture

    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)

    2012-05-01

    Full Text Available Groundwater samples were collected from different parts of Akure town and analysed for various physico-chemical parameters using conventional field and laboratory techniques. The essence of the study is to evaluate the characteristics and quality assessment of groundwater in the area. The pH values falls between 7.1 to 7.7, indicating that the ground water is neutral. The range of conductivity for the area is between 116 to 1000µS/cm with an average of 365µS/cm which met the WHO (2006 standard of 1000µS/cm for drinking water. The low levels of turbidity ranging from 1 to 2 NTU were obtained. The TDS concentrations range between 81 to 700 mg/l. The total hardness of water sampled range from 20.2 to 345.6mg/l. Sulphate ion concentration is between 2.5 to 23.2mg/l. Phosphate values ranges from 0.05 to 0.07mg/l in all locations, and average value of 0.12mg/l which are within the WHO (2006 standards for drinking water. Nitrate levels ranged from 1.13 to 2.91mg/l. The values of bicarbonates range from 28 to 88mg/l with a mean value of 43.9mg/l, as all locations are far below the W.H.O (2006 limit of 600mg/l. The concentration of calcium ranged from 12.3 to 92.2mg/l while the concentrations of magnesium ion ranged from 0.9 to 32.6mg/l with an average of 7.3gm/l and this is below the WHO limit for drinking water (150mg/l. The concentration of sodium ion (Na+ ranged from 1.067 to 8.696mg/l. The concentration of potassium also ranged from 7.537 to 51.881mg/l with a mean value of 19.098mg/l. Although there is no reference to WHO standards for the parameter, the relatively low values of potassium suggest the suitability of the analysed groundwater samples for drinking. The common form of iron in groundwater is the soluble ferrous ion Fe2+. The concentration of iron in the water samples ranged from <0.001 to 0.001mg/l showing a very low value of iron in all boreholes. Generally, results compare favourably with the WHO (2006 standards for drinking water

    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

    Full Text Available Zinc (Zn content was evaluated of the arable soils in the vicinity of mining and dumping sites in Nigeria. Its content the arable soils assayed by means of Atomic Absorption Spectrophotometry (AAS ranged from 48.3 to 280.4 mg/kg. The Enrichment Factor (EF calculated by using manganese as a crustal reference element fell within a range of 16.3-161.2. The mean values of the enrichment factor of 59.41 classified the soil as extremely high enrichment with zinc. Anthropogenic activities contribute significantly to the elevated level of zinc in the studied areas.

  18. Assessment of the quality of antenatal care services provided by health workers using a mobile phone decision support application in northern Nigeria: a pre/post-intervention study.

    Marion McNabb

    Full Text Available Given the shortage of skilled healthcare providers in Nigeria, frontline community health extension workers (CHEWs are commonly tasked with providing maternal and child health services at primary health centers. In 2012, we introduced a mobile case management and decision support application in twenty primary health centers in northern Nigeria, and conducted a pre-test/post-test study to assess whether the introduction of the app had an effect on the quality of antenatal care services provided by this lower-level cadre.Using the CommCare mobile platform, the app dynamically guides CHEWs through antenatal care protocols and collects client data in real time. Thirteen health education audio clips are also embedded in the app for improving and standardizing client counseling. To detect changes in quality, we developed an evidence-based quality score consisting of 25 indicators, and conducted a total of 266 client exit interviews. We analyzed baseline and endline data to assess changes in the overall quality score as well as changes in the provision of key elements of antenatal care.Overall, the quality score increased from 13.3 at baseline to 17.2 at endline (p<0.0001, out of a total possible score of 25, with the most significant improvements related to health counseling, technical services provided, and quality of health education.These study results suggest that the introduction of a low-cost mobile case management and decision support application can spur behavior change and improve the quality of services provided by a lower level cadre of healthcare workers. Future research should employ a more rigorous experimental design to explore potential longer-term effects on client health outcomes.

  19. Assessment of electricity generation and energy cost of wind energy conversion systems in north-central 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%.

  1. Assessing gaps and poverty-related inequalities in the public and private sector family planning supply environment of urban Nigeria.

    Levy, Jessica K; Curtis, Sian; Zimmer, Catherine; Speizer, Ilene S

    2014-02-01

    Nigeria is the most populous country in Africa, and its population is expected to double in Intelligence Agency 2012; Fotso et al. 2011). Over half of the population already lives in an urban area, and by 2050, that proportion will increase to three quarters (United Nations, Department of Economic and Social Affairs, Population Division 2012; Measurement Learning & Evaluation Project, Nigerian Urban Reproductive Health Initiative, National Population Commission 2012). Reducing unwanted and unplanned pregnancies through reliable access to high-quality modern contraceptives, especially among the urban poor, could make a major contribution to moderating population growth and improving the livelihood of urban residents. This study uses facility census data to create and assign aggregate-level family planning (FP) supply index scores to 19 local government areas (LGAs) across six selected cities of Nigeria. It then explores the relationships between public and private sector FP services and determines whether contraceptive access and availability in either sector is correlated with community-level wealth. Data show pronounced variability in contraceptive access and availability across LGAs in both sectors, with a positive correlation between public sector and private sector supply environments and only localized associations between the FP supply environments and poverty. These results will be useful for program planners and policy makers to improve equal access to contraception through the expansion or redistribution of services in focused urban areas. PMID:24248622

    The paper reports on progress by the Government of Sri Lanka in the implementation of a formal environmental impact assessment (EIA) requirement. The authors have recently conducted several activities in Sri Lanka intended to improve the analytical quality of EIA documents and the utility of the EIA process in government decisionmaking, with particular attention to the use of programmatic or sectoral EIAs. The U.S. Agency for International Development established a 5-year project, the Natural Resources and Environmental Policy Project (NAREPP), to provide training and technical assistance in EIA and related disiplines for the Central Environmental Authority (CEA), several other Sri Lanka government agencies, and the private sector. This activity has involved efforts to expand the technical expertise within Sri Lanka for conducting EIA, which include developing EIA courses and materials in cooperation with several universities and conducting intensive training programs for both government and private-sector environmental professionals. This EIA will focus on the selection of government-approved industrial estates throughout the country, on which most new industrial development projects are to be located. Further training programs in the use of current analytical methodologies for EIA were also developed and conducted. The effectiveness of these activities can be assessed by evaluating changes in the content and quality of subsequent EIA documents and in the extent to which such documents affect environmental decisionmaking in Sri Lanka. The authors discuss the role of the programmatic EIA in the industrial development program of Sri Lanka, remaining constraints on the EIA process, and recommendations for further improvement.

    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.

    Full Text Available Cervical cancer is the leading cancer-related cause of death among women in Nigeria. An estimated 70,700 new cases occur each year, representing one quarter of all female cancers in sub Saharan Africa. The magnitude of the problem has been under recognised and under prioritised compared with the competing health priorities of infectious diseases such as HIV/ AIDS, tuberculosis and malaria. Studies in the United States and Nigeria have indicated that the disease has the highest incidence among the lowest socio-economic groups especially residing in rural areas. The peak age for the disease has been shown to be within 35-45 years age group. Knowledge of the risk factors of the disease is deemed important in its early detection and prevention. The objective of this study was to assess the knowledge, attitude and practice of rural women with cancer of the cervix. A cross sectional descriptive study was conducted among 1600 rural women aged 15-55 years (randomly selected from 28 villages who were interviewed using a structured questionnaire between April and June, 2010. The majority (82.2% were married before the age of 20 years and 19.3% before 15 years, 40% in polygamous union, 22.6% have had 2 or more sexual partners, 71.3% were primi and grand multiparous, 7.5% have had previous treatment for STIs and 10.1% were on various types of contraceptive. 454 (28.4% have heard of Ca cervix, 358 (22.4% knew the location of the cervix. 2.3% had Pap smear test of which 72.6% were within 2 years. The majority (89.9% will avail themselves for screening.

  7. Analysis of Settlement Expansion and Urban Growth Modelling Using Geoinformation for Assessing Potential Impacts of Urbanization on Climate in Abuja City, Nigeria

    2016-03-01

    Full Text Available This study analyzed the spatiotemporal pattern of settlement expansion in Abuja, Nigeria, one of West Africa’s fastest developing cities, using geoinformation and ancillary datasets. Three epochs of Land-use Land-cover (LULC maps for 1986, 2001 and 2014 were derived from Landsat images using support vector machines (SVM. Accuracy assessment (AA of the LULC maps based on the pixel count resulted in overall accuracy of 82%, 92% and 92%, while the AA derived from the error adjusted area (EAA method stood at 69%, 91% and 91% for 1986, 2001 and 2014, respectively. Two major techniques for detecting changes in the LULC epochs involved the use of binary maps as well as a post-classification comparison approach. Quantitative spatiotemporal analysis was conducted to detect LULC changes with specific focus on the settlement development pattern of Abuja, the federal capital city (FCC of Nigeria. Logical transitions to the urban category were modelled for predicting future scenarios for the year 2050 using the embedded land change modeler (LCM in the IDRISI package. Based on the EAA, the result showed that urban areas increased by more than 11% between 1986 and 2001. In contrast, this value rose to 17% between 2001 and 2014. The LCM model projected LULC changes that showed a growing trend in settlement expansion, which might take over allotted spaces for green areas and agricultural land if stringent development policies and enforcement measures are not implemented. In conclusion, integrating geospatial technologies with ancillary datasets offered improved understanding of how urbanization processes such as increased imperviousness of such a magnitude could influence the urban microclimate through the alteration of natural land surface temperature. Urban expansion could also lead to increased surface runoff as well as changes in drainage geography leading to urban floods.

    Full Text Available Water exploitation and population explosion are two major problems facing Nwangele Local Government. This study was therefore predicated on these problems to assess the underground water and pollution vulnerability of the study area. 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

    Charity Akuadi Okonkwo

    2012-04-01

    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.

    2012-07-01

    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.

  13. An Assessment of the Efficiency of Government Regulatory Agencies in Nigeria. Case of the National Agency for Food and Drugs Administration and Control

    Aiwanehi Barbara Ofuani

    2015-09-01

    Full Text Available This study examines Business, Government and Society interrelationships. It eventually narrowed down to assessing the efficiency of government regulatory agencies, in fulfilling the role of government in protecting consumers from unscrupulous practices of businesses. The National Agency for Food and Drugs Administration and Control (NAFDAC was chosen for the study. Since the expectations of the consumers are paramount here, the stakeholder approach method was used for assessing the efficiency of NAFDAC. Literature and previous empirical studies on the topic were examined. For representativeness, data was collected utilizing the survey research design through Questionnaire distributed to 200 respondents in some areas of Lagos Mainland in Lagos state, using the convenience sampling method. 187 copies of the questionnaire representing 93.5% were returned and usable. Descriptive statistics was used to analyze the responses to questions regarding the efficiency of NAFDAC and a hypothesis tested using a one-sample T-test. The findings ran contrary to results from some previous studies. Instead, consumer awareness of the existence of NAFDAC as a regulatory agency and its functions were established, along with a high rate of consumer education. The assessment of its efficiency also showed a high rating. Recommendations were made that the study be replicated in other states of Nigeria and further studies carried out to evaluate its efficiency under previous and current directors for improvement purposes.

  18. Assessment of Human Exposure to Magnetic Field from Overhead High Voltage Transmission Lines in a City in South Western Nigeria

    Ponnle Akinlolu

    2015-05-01

    Full Text Available The increase in electricity consumption, population, and land use has now forced high voltage transmission lines (HVTLs either to pass or be installed around or through urban cities. This increases the level of human exposure to electromagnetic field radiation as this field produced around the HVTLs extends outwards covering some distance. This may cause a number of health hazards. It is even dangerous to a human who touch any metallic object in proximity of the HVTL, as it may have an appreciable voltage induced on it due to inductive, capacitive or resistive interference from the line. This paper evaluates the magnetic field produced at mid-span by a 132kV, and a 330kV, 50Hz adjacent HVTLs with horizontal and vertical configuration in Akure, a city in South Western Nigeria using analytical method from electromagnetic field theory. This is then compared to the recommended standard limit of public exposure to magnetic field. The results of the computation showed that currently, the general public exposure to the magnetic field along the HVTLs is safe. However, right of way (ROW along the power lines is being violated as buildings and work places exist within the ROW.

    2010-04-01

    Full Text Available Objectives: Poor interpersonal relationships with women especially those living positively with HIV/AIDS can make them take risks that would expose their new born and others to infection during childbirth. The factors that influence childbirth choices of people living positively with HIV/AIDS (PLWHA deserve attention. Sometimes, women, especially PLWHA, for several reasons, resort to the use of other health care services instead of the general hospitals equipped for ante-natal care (ANC. This study aims to identify factors and conditions that determine childbirth choices of PLWHA in the Abia State of Nigeria.Methods:A cross-sectional descriptive study was carried out using a total sample of 96 PLWHA who attend meetings with the network of PLWHA and also a purposive convenience sample of 45 health workers. Data collection instruments were questionnaire, focus group discussions and interview guides. Data was analyzed both qualitatively and quantitatively using simple percentages.Results: There was a low patronage for hospital services. A total of 79 (82% PLWHA did not use hospital services due to the lack of confidentiality. In total, 61 (64% PLWHA had their childbirth with Traditional Birth Attendants (TBAs at home. Embarrassment, rejection, interpersonal conflicts with health workers, non-confidentiality, cultural stigma and stigmatization were among the factors that encouraged childbirth choices. On the whole, 82 (85% of the PLWHA discontinued ANC services because of stigmatization.Conclusion: Poor interpersonal relationships between health workers and PLWHA facilitated PLWHA childbirth choices more than other factors. PLWHA and health workers termed management of belligerent tendencies against each other as their greatest concern. Therefore, concerted effort is needed to improve health workers/PLWHA relationship in hospitals. This would minimize factors and/or conditions that encourage HIV infection. Exposing PLWHA to factors that influence

  3. Assessment of the Chemical Characteristics of a Spring Water Source at Ife-Owutu, Ezinihite-Mbaise, Southeastern Nigeria.

    Ibeneme, S.I.

    2013-10-01

    Full Text Available The chemical characteristics of the Giri Giri Nwanjoku Spring in Owutu Ezinihitte-Mbaise, South Eastern Nigeria was investigated to carefully determine some basic geochemical constituents of the water sourcewith a view to identifying those constituents whose concentrations are unacceptably high, compared with the maximum permissible level of a regulatory body and as such determine its wholesome portability for diverse usage. The resultant data conform to the Nigerian Industrial Standard (2007 and the World Health Organization (2006 Standard. The water source is generally neutral with an average pH of 6.85. However, the samples gave an average Calcium and Magnesium ion concentrations of 3.205mg/l and 0.82mg/l respectively and an average hardness (as CaCO3 of 11.375mg/l, indicating that the water is relatively soft. The Stiff and Schoeller plots show at a glance the spatial variations of the chemical constituents of the spring with Tri-oxo-carbonate and Calcium dominating. From the Box and Whisker plot, the greater amount of the cations and anions lie within the second quarter of the box ranging from 0.01meq/l to 0.05meq/l indicating similarity in origin. The Piper trilinear diagram reveals an alkaline earth and weak acid group predominantly the Tri-oxo-carbonate and as suchclassified as Ca-(Mg-Na-HCO3 water facies which indicates portability. The Sodium Absorption Ratio (SARand Percentage Sodium (%Na values of 0.27 and 34.20% respectively show that the water is good for Agricultural use. The Pollution Index (PI value of 0.6 (which is less than the critical value of unity shows thatthe spring water is not polluted. For industrial use, the Saturation Index (SI value of -3.41 reveals that the water may lead to moderate corrosion if not properly treated.

    2014-09-01

    Full Text Available Malaria is one the major health problem in Nigeria. During pregnancy, it poses serious threat to the survival of both unborn foetus and the mothers. This study determined the effect of adequate malaria knowledge and pregnancy status of women on use of mosquito nets and reported malaria fever morbidity.The data were collected during the Malaria Indicator Survey (MIS from 4632 women. Data analyses were carried out with descriptive statistics and Seemingly Unrelated Bivariate Probit regression.Results show that 13.19% of the women were pregnant, of which about one-third slept under mosquito nets. Also, 25.26% reported malaria associated fever in the previous two weeks to the time of interview, while 78.28% correctly answered that mosquitoes are responsible for malaria. Knowledge on malaria prevention was low with 55.70% and 14.93% indicating sleeping under mosquito nets and ITN, respectively. Probability of sleeping under mosquito nets significantly increased with knowing that sleeping under mosquito nets and ITN could prevent malaria while it decreased with having fever, age, urban residence and knowing that use of mosquito spray and coil can prevent malaria. The probability of having fever increased significantly with household size, being pregnant and age at first birth but decreased with age, knowing that sleeping under ITN, cutting grasses and closing door/windows would prevent malaria.Use of mosquito nets among the women was low. Also, efforts to enhance their knowledge on malaria prevention and ensuring adequate access to mosquito nets especially for pregnant women would curtail the impact of malaria.

    Full Text Available This study analyses the academic achievement of students enrolled in part-times studies at on-campus and outreach centres at three dual-mode Nigerian universities, during the 1996/97 to 1998/ 99 academic years. Research subjects in this study were examination and record officers employed by on-campus and outreach institutions. A checklist was prepared to collect students’ grades; these checklists were then transcribed into grade points (GPAs for data collection purposes. Simple percentage mean (x and t-test statistic were used for data analysis. Interviews were also conducted with key stakeholders to add qualitative context to the quantitative data collected. This study shows that there was significant difference in the academic performance of students enrolled in the on-campus versus outreach-based, part-time programmes in selected disciplines. Also the average mean (x performance of students enrolled in the on-campus programme was higher than those students enrolled in the outreach centres. Based on the findings of this study, it is recommended that the government provide adequate funding to increase access individuals seeking higher education in Nigeria. The establishment of functional Open University system is also recommended to provide students with distant learning opportunities and likewise increase access. Several quality improvements are likewise recommended: the use of modern information technology for instructional delivery, recruitment of skilled teachers, improved teaching/ learning facilities, and strict adherence to standardized student admission requirements as specified by the National Universities Commission (NUC. We wrap up with practical suggestions, such as providing orientation sessions for outreach students to learn practical skills such as how to access library materials.

  10. Tubular biomarkers to assess progression of diabetic nephropathy.

    Tramonti, Gianfranco; Kanwar, Yashpal S

    2011-05-01

    Despite aggressive management, many patients with diabetic nephropathy still develop end-stage renal disease. Accompanying tubulointerstitial damage is important in the progression of diabetic nephropathy. Markers of tubular damage, such as NGAL, KIM-1, and LFABP, have been proposed for monitoring the effectiveness of therapy. However, Nielsen et al. report a lack of an independent correlation between these biomarkers and glomerular filtration rate. Therefore, these markers seem to offer no improvement in the management of diabetic nephropathy. PMID:21527942
