Chemical characterisation of palm kernel (Elaeis guineensis Jacq.), shea butter (Vitellaria paradoxa C.F. Gaertn.) and sesame (Sesamum indicum L.) seed oils as ingredients in breeding broiler diets

Lipids are important to both humans and livestock where they play important role as an excellent source of energy and enhances the absorption of fat-soluble vitamins. However, oils are used in formulation without any considerations given to the peculiarities of their innate constituents particularly, vitamin, fatty acids and phytochemicals. Thus, the basis of these determinations. Three lipids: palm kernel oil (PKO), shea butter (SB) and sesame seed oil (SSO), were analyzed chemically in triplicate using standard methods. Results showed that SB had the highest (p<0.05) peroxide value (meq/kg) of 7.4 while PKO (0.7) and SSO (0.3) were similar (p>0.05). The iodine values (g/100g) of the lipids were not significantly different (p>0.05). The saponification value (mgKOH) of PKO (249.9) was significantly higher than SBO (190.9) and SSO (15.8) while the acid value (mgKOH/g) of SBO (10.6) was significantly lower (p<0.05). The α-tocopherol of SBO was 119.2 μg/mL which was significantly higher (p<0.05) than 69.6 μg/mL in SSO and 24.4μg/mL in PKO while there were significant variations (p<0.05) in the fatty acid composition of the oils. Analyses revealed the oils possessed variable chemical characteristics; while PKO would be most appropriate for soap production, SBO and SSO would be more susceptible to rancidity.

Psidium guajava extract reduces trypanosomosis associated lipid peroxidation and raises glutathione concentrations in infected animals

We have investigated the effects of the aqueous leaf extract of P. guajava on reduced glutathione (GSH) and alondialdehyde (MDA) concentrations in rats experimentally infected with Trypanosoma brucei brucei. The results obtained showed that the MDA concentrations in the serum and tissues of the infected animals were significantly increased (P0.05) (Table 1). In contrast, a significant decrease (P<0.05) was observed for the GSH concentrations in the liver and kidney for the infected animals compared to the uninfected control and the infected but treated groups. The MDA concentrations in the serum and tissues of the infected but treated animals were significantly reduced when compared to the infected groups (P<0.05) (Table 2). In this study it was demonstrated that the aqueous extract was able to reduce the trypanosomosis associated lipid peroxidation as well as raise the level of GSH in the infected but treated animals significantly (P<0.05). We present evidence that the ability of the leaf extract of P. guajava to lower the MDA concentrations in the treatment group may be attributed to its antioxidant properties

Stigma from psychoactive substance use: Sociodemographic correlation of the perceiver

Psychoactive substance use and abuse have been identified as the most stigmatized health condition. This often arises from ‘public’, ‘self’ and ‘courtesy’ stigmas and biases. In Nigeria, studies on stigma of psychoactive substance use and abuse are few and mainly from the perception of medical service providers. No previous Nigerian study according to search by the authors had published on stigma of psychoactive substance use from the perspectives of non-medical persons. This research is therefore aimed to study the prevalence and associated sociodemographic variables of public stigma meted out to users of psychoactive substances. The study instruments were filled by 480 members of staff of Kaduna refinery after obtaining their informed consents. Information on age, gender, educational characteristics and scores on Perceived Stigma of Addiction Scale (PSAS) were collected and analysed with IBM-SPSS version 21. Participants with no formal education are noted to have high public stigma against substance abusers. Belonging to middle age group and male gender are the two demographics that have non-significant low stigma mean scores. It is hoped that this study do provide a platform for interventional guide in reducing and preventing public stigma towards people with psychoactive substance use disorder.

Comparative study of Ikirun and Osogbo Slag on concrete grade 20

This study examined the use of Prism Steel Slag (PSS) and Machine Iron Slag (MIS) as partial replacement of coarse aggregate in concrete. Coarse aggregates were partially replaced with PSS and MIS at 0%, 10%, 20%, 30%, 40% and 50% respectively. A total of 132 concrete cubes of sizes 150 mm x 150 mm x 150 mm were cast and cured in water for 7, 14, 21 and 28 days respectively. Mix ratio of 1:2:4 was adopted with w/c ratio of 0.45 and batching was done by weight. The slump result indicated that the fresh concrete becomes stiff as the percentages of PSS and MIS increases. However, the compressive strengths of concrete cubes increased as the curing ages increases. 50% PSS and 40% MIS can successfully be used as partial replacement of coarse aggregate in the production of concrete grade 20.Keywords: Concrete, Coarse Aggregate, Strength, Machine Iron Slag, Prism Steel Sla

Effects of Time of Weed Removal on Weed Species Composition and Crop Performance of Okra (Abelmoschus esculentus (L.) Moench)

The effect of time of weed removal on weed species composition and crop performance of okra (Abelmoschus esculentus (L.) Moench) was assessed in the early and late seasons of 2002 in Ondo (07° 05’N, 04° 55’E). Okra plots weeded at 2, 4. 6, and 8 weeks after planting (WAP) were compared with weed free (WF) and weedy (WY) okra in a randomized complete block design and replicated three times. Weed removal (WR) at 8 WAP was similar to weedy check with regards to crop growth parameters. Plant height, stem girth, nodes per plant, total dry matter, shoot dry matter, mean root length, number of roots, root dry weight, shoot/ total dry weight ratio (SWR) and root/total dry weight ratio (RWR) were superior in the early season to the late season. However number of leaves/plant, number of branches/plant and leaf area/plant were better in the late season than in the early season. Pod number, pod length and fruit yield/plant were also higher in the late season than early season, except weedy throughout and WR at 8 WAP.  WR at 4 WAP gave comparable values of plant height, number of leaves per plant, leaf area per plant, mean root length, root dry weight, pod number, pod length and pod yield with WF. The order of pod yield was WF &gt;WR at 4 WAP &gt;WR at 6 WAP &gt;WR at 8 WAP &gt;WY. The critical time of weed removal in okra production under the condition of this experiment was 4 WAP. Uncontrolled weed infestation in okra resulted in 39 % and 84 % reduction in potential okra fruit yield compared with the maximum obtained from the WF okra in the early and late seasons, respectively. It is suggested that plot be weeded early (4 WAP) for optimum growth and yield of okra. Keywords: weed removal, weedy check, weed species, okra, weed- fre

LANDFILL SITE SELECTION IN ADO-ODO OTA LGA USING GEOGRAPHIC INFORMATION SYSTEMS

This study makes an attempt at determining suitable landfill sites in Ado-Odo, Local Government Area, Ota, Ogun State, Nigeria. A multi-criteria evaluation method is applied based on Geographical Information System to identify potentially favourable landfill sites in the study area. The landfill siting process requires the evaluation of several criteria such as land use, vegetation classification, road networks, water bodies and so on based on complex operations on databases containing spatial data of these criteria. The model chosen for site selection involved four (4) stages viz: preliminary analysis, creation of constraint maps, creation of final constraint overlay maps, and creation of final suitability maps depicting suitable areas. The first stage involves the creation of various maps for the study area to input the data layers. The second stage involves the creation of constraint maps using available spatial data which implies the creation of buffered distances according to stipulated criteria. The final constraint map overlay is created by merging all the data layers from the constraint maps. In addition, the final suitability map is created via the use of spatial analysis tools. This final map can be used by the state, local government and its policymakers on their choices of suitable and unsuitable sites that pose no threat to the health of its citizens, as well as minimal damages to the environment
