MARRIAGE PRESSURES AND PERCEPTION OF SINGLEHOOD AMONG YET-TO-MARRY WOMEN IN IBADAN METROPOLIS

Despite the critical disapproval of singlehood in most African societies, Nigeria inclusive, it is most appalling that the age at which women make their first nuptial bliss is becoming late in recent times. Statistics have shown that the number of single women have doubled within a short space of time. The available chunk of studies have paid sufficient attention to the factors responsible for singlehood among older women. However, little studies have examined how different source marriage pressures influence how single women view themselves. Against this background, this article examines the sources of marriage pressures and how they influence the perception of singlehood among women in Nigeria. The study draws heavily on Marx Weber Social Action theory. A total of 24 yet-to-marry women selected through a multistage sampling technique were extensively interviewed. The study found that beside the direct marriage pressure from parents experienced by yet-to-marry women, they are also faced with indirect marriage pressure during gatherings with family, friends, and co-workers. The pressures sometimes translate to the women perceiving themselves as being judged, though most of them feel independent and free. They are of the opinion that they need to be careful in selecting a partner in order not to fall victim of a failed marriage despite having waited for long.     &nbsp

Sexual networking, STDs and HIV/AIDS in four urban gaols in Nigeria

Truck drivers, female hawkers and prostitutes are generally regarded as high-risk groups because they have a high rate of partner change, run abnormally high risks of being infected with sexually transmitted diseases (STDs) including HIV/AIDS, and are capable of transmitting them to the general population who live around them (Orubuloye, Caldwell and Caldwell 1993; Orubuloye 1995). Recent experience has shown that the prison population runs a high risk of being engulfed by AIDS. By late 1992, HIV-positive prisoners had been detected in at least one of the prisons in Nigeria and there was beginning to be concern for the safety of the prison population. Therefore a study of the prison population was planned as part of a larger continuing research program of the Ondo State University, Ado-Ekiti, Nigeria, on Sexual Networking, STDs and HIV/AIDS Transmission, supported by a grant from the Swedish Agency for Research Cooperation with Developing Countries (SAREC). The aim of the prison study was to investigate the attitudes and activities that are likely to facilitate the spread of sexually transmitted diseases, HIV and AIDS; and to develop an intervention program for the prison population and any population that may be in a similar situation

THE COMPARATIVE ROLE OF ASCORBATE AND CHELATORS IN REVERSING OXIDATIVE STRESS, HEPATIC AND RENAL DYSFUNCTION IN SUB-ACUTE LEAD POISONING

Lead has been implicated in the induction of reactive species production, leading to organ dysfunctions. The ameliorative roles of ascorbate and chelators in acute lead poisoning were comparatively studied in thirty-five male Wistar rats (150-200g), segregated into 5 groups (n=7/Group): group 1(administered normal saline),ª¤? groups 2-5 were orally exposed to 75mg/kg body weight lead acetate (PbAc) daily for 14 days. Pre-therapy blood samples were collected to ascertain blood lead level (BLL) and catalase activity 24hours after the last PbAc exposure. Groups 3, 4, and 5 were then treated with 30mg/kg body weight D-penicillamine; 30mg/kg body weight succimer; and 500mg/kg body weight ascorbate respectively for 10 days, followed by the assay for indices of oxidative stress, hepatic and renal dysfunctions.ª¤? Results obtained showed significantly elevated BLL in the four groups exposed to PbAc. which were significantly reversed about 2 folds in groups 3-5 after therapeutic interventions. Pre-therapy blood catalase activity of the PbAc treated groups was significantly (p<0.05) reduced by 39% when compared with the control group, however ascorbate significantly (p<0.05) increased catalase activity by 2 folds above the control; decreased plasma activities of alanine transaminase and aspartate transaminase, blood urea nitrogen and creatinine among the groups administered therapeutics. These findings indicate that ascorbate is more effectiveª¤

Effects of Na2Cr2O7 Inhibitor on the Corrosion Potential Response of Steel Reinforced Concrete in Saline Medium

Electrochemical monitoring method of the open circuit potential was used to investigate the effect of the concentrations of Na2Cr2O7 on the corrosion potential response of steel reinforced concrete in sodium chloride medium. In the study, five different concentrations of Na2Cr2O7 admixtures were employed in a system of replicated samples of steel-reinforced concrete specimens partially immersed in 3.5% NaCl to simulate marine and saline environments. Forty days measured responses from these were subjected to the statistical analyses of the Normal and the Weibull distribution functions and tested using the Kolmogorov-Smirnov goodness of fit criteria. Results obtained from the analyses identified 4 g Na2Cr2O7 with optimal averaged potential response inhibition performance by the Normal model which showed better agreements in its models of Na2Cr2O7 potential test data than that obtained from the Weibull model of the same data. These bear pertinent implications on the need for suitability studies of appropriate statistical distribution for studying performance of corrosion inhibitors even as suggestions were proffered for addressing results conflicts among replicates of steel reinforced concrete samples employed

MODELING AND SIMULATION OF MECHANICAL PROPERTIES OF PULVERIZED COW BONE AND LATERITIC PAVING TILES

This study included the experimental production and investigation of the mechanicalproperties of paving tiles produced from a mixture of laterite, silica sand, pulverized cow bones,and cement. Empirical models of compressive and flexural strength were also developed andherein presented for the paving tiles. The maximum compressive strength of the paving tiles wereobtained for 20, 15, and 10% cement content as 5.05, 5.05 and 3.08 MPa, while the maximumflexural strength for similar values of cement content were obtained as 1.83, 1.21 and 0.26 MParespectively. The results indicate that there was no noticeable difference in the values of thecompressive strength at 20 and 15% cement content, while a sharp reduction of the mechanicalproperties was experienced as the cement content reduces from 15 to 10%. Recommendedcomposition for paving tiles with pulverized cow bones composite is cement, 15%; pulverized cowbones, 30%; laterite 35% and silica sand, 20% respectively. Sustainable production of paving tilesand a sustainable environment can, therefore, be enhanced by replacing granite constituent withwaste cow bones, which can easily be replicated by the empirical models herein developed

Synthesis and Characterization of Graphene-Cu Composite Via Hydrothermal Method

In this paper, graphene-copper composite was synthesized via hydrothermal method using different compositions from 5 to 25%. The grain size and copper composition are observed to decrease proportionally to increase in band gap. The effect of composition fluctuate the peaks shift. The peak increased linearly with increasing temperature for each composition. The band gap reduces with increasing temperature for each composition. Short calcined duration on samples is observed to cause a little lower band gap value than that of longer duration. The thermal treatment of graphene oxide (GO) has been observed to cause changes in its quality, size and shape. &nbsp

PERFORMANCE CHARACTERISTICS AND RUMEN MICROBIAL POPULATION OF WEST AFRICAN DWARF SHEEP FED ENZYME SUPPLEMENTED DIETS

A 56-day trial was conducted to determine the effect of exogenous fibrolytic enzyme on growth per-formance and rumen microbial population of West African dwarf sheep. Sixteen growing ewe were randomly subjected to four dietary treatments with four animals per treatment in a completely random-ized design. A total mixed ration was formulated with enzyme included at four levels: 0, 0.2, 0.4 and 0.6 g/kg feed. Performance characteristics and rumen microbial population of the animals were deter-mined. Enzyme additive significantly influenced (P<0.05) weight gain, feed intake and feed conversion ratio. The highest values for total weight gain, and total feed intake were obtained at 0.6g/kg enzyme inclusion level. The feed conversion ratio (12.63) was however lowest (P<0.05) at 0.4g/kg enzyme inclusion. The total bacteria and total fungi counts were also significantly (P<0.05) affected by the dietary treatments. The highest bacteria (4.73×106 cfu/ml) and fungi counts (3.27×106 cfu/ml) were obtained at 0.6g/kg enzyme inclusion level but these values were not significantly different from what was obtained at that of 0.4g/kg enzyme inclusion. Protozoa count was not significantly (P>0.05) af-fected by the dietary treatments. A total of eight bacteria were isolated in the rumen of the animals. It is therefore concluded that the enzyme additive improved the performance and microbial count of sheep when added at 0.4g/kg feed

Proximate Composition and Metabolizable Energy of Some Commercial Poultry Feeds Available in Abuja, Nigeria

Poultry feeds are prepared to contain all the nutrients in their right proportions necessary for good health, proper growth and egg production of the chicken. This study was undertaken to determine the proximate composition and variations of nutrient in some commercial poultry feeds sold in Abuja, Nigeria. Seven poultry feed brands in their various ratios were subjected to proximate analysis using standard methods. The results of the analysis revealed that the poultry feeds had proximate composition ranging from 6.58 ± 0.02 - 10.88 ± 0.19 % moisture content, 6.03 ± 0.16 - 14.78 ± 0.73 % ash content, 9.98 ± 0.81 - 20.05 ± 0.08 % crude lipid, 3.57 ± 0.11 - 14.77 ± 0.14 % crude fiber, 16.55 ± 0.07 % - 34.01 ± 0.09 % crude protein, 26.28 ± 1.80 % - 48.21 ± 2.07 % carbohydrate and 2971.48 ± 65.44 - 3686.18 ± 29.08 Kcal/kg metabolizable energy. Generally, there were differences in the proximate composition of the poultry feed brands analyzed, however, the poultry feeds have optimum nutrients in their feeds which meet most of the requirements recommended by SON and NRC. The moisture contents in all the feeds were within the recommended value of not more than 12 % while the mean values obtained in crude lipid were all higher than the maximum recommended requirements in poultry feeds

GROWTH RESPONSE OF BROILER BIRDS FED Asystasia gangetica LEAF MEAL IN HOT HUMID ENVIRONMENT

A 35- day feeding trial was conducted to study the effects of inclusion of Asystasia gangetica leaf meal (AGLM) on the growth response of broiler chickens. Samples of Asystasia gangetica leaves were sourced from the Federal University of Agriculture, Abeokuta environment. The leaves were chopped and wilted, sun dried to reduce the moisture level to the minimal level. The dried leaves were milled to produce leaf meal. Asystasia gangetica leaf meal contain 19.38% crude protein, 15.30% crude fibre, 12.70% ether extract, 1.70% ash and 36.34% NFE.  A total number of 120 day old Marshal Strain of broiler chicks was used. A standard starter diet was fed to the birds prior to the commencement of the experiment. At the end of the 3rd week, birds were allotted into four treatments having three replicates of 10 birds each. Four experimental diets were formulated with varying levels of A. gangetica leaf meal (0, 2.5, 5.0 and 7.5 %) respectively.  Final live weight and daily weight gain varied significantly (P<0.05) among treatment groups. The feed intake and feed conversion ratio were not significantly influenced (P>0.05) by dietary treatments. Final weight and weight gain values were found to decrease across the dietary treatments with increasing level of A. gangetica leaf meal. The results of the experiment show that the use of A. gangetica as feed ingredient in broiler production significantly depressed growth.Â
