    Water Absorption is one of the properties that determine the suitability of rattan canes as structural material especially for outdoor use. This study therefore evaluated the water absorption characteristics of two rattan species (laccosperma secundiflorum and eremospatha macrocarpa) from a fresh water swamp, Arapagi village, Lagos state and rain forest-Nicholas village, Edo state in Nigeria by collecting three matured wild rattan species from each ecological location and the water absorption carried out after 24 hours and 48 hours respectively. The results show that, water absorption after 24 hours ranged from 39.63 % to 82.51%. However, water absorption after 48hours increased from 44.53 % to 93.74 %. It was also observed that water absorption after 24 hours and 48 hours increased along the axial direction from base to top. Meanwhile, the samples of the two rattan species sourced from Rain forest had lower water absorption values than Fresh water swamp. In conclusion, the two rattan species had different levels of water affinity, however, samples obtained at the base from Rain forest absorbed less water

    This experiment was carried out to evaluate the potential of extracted Datura metel seed oil as a  bio wood preservative against fungi attack as reports have shown bio-preservatives to be toxic free and environmentally friendly. The oil was extracted from the seed by Soxhlet apparatus using N-Hexane and ethanol solvents and using volume-to-volume method of dilution kerosene (at 50%) was added to increase its quantity thereafter. The phytochemical screening of the seed of Datura metel revealed the presence of tannins, alkaloids, flavonoids, saponins and phenols. Wood samples of Triplochiton sceleroxylon  were cut to 20 × 20 × 60mm and the dimensioned wood samples were soaked for 72 hours in the seed oil extract hence preservative absorption rate and percentage weight loss of wood  was determined on exposure to a purely cultured Sclerotium rolfsil (brown rot fungi) and Pleurotus ostreatus(white rot fungi). Data obtained were subjected to analysis of variance at α0.05 and the results showed the highest value of mean weight loss of 18.29% while the samples exposed to brown rot fungi has a mean value of 14.12% and white rot a lowest mean value of 12.72%. The highest absorption was observed to be 92.73 kg/m at 100 % concentration level of D,metel extract.  Based on the results obtained, the seed-oil extracts of Datura metel have the potential of being an effective wood preservative

    Abstract Tropical trees had served a wide range of purpose from supply of timber, fuel wood, pulp and fibre through to fodder, gum, drugs, and dyes. This study considered the fodder yield and leaf quality of three fodder tree species namely: Moringa oleifera, Albizia lebbeck and Gmelina arborea at seedling stage. The experiment was carried out in polythene pot laid out in a completely randomized design with ten replications. Study spanned over a period of twelve weeks. Seedlings were assessed for plant height, number of leaves and stem diameter. Leaf quality parameters assessed were elemental nutrient and proximate composition. Results obtained from the study showed that Moringa oleifera gave the highest mean plant height and mean stem diameter of 30.93cm and 3.52mm respectively while Gmelina arborea recorded the highest mean number of leaves (8.10) over the study period. Leaf quality analysis revealed that Albizia lebbeck leaves were richest in potassium and copper with values of 5.53% and 24.23mg/g respectively. Moringa oleifera was least in potassium content (4.55%). Proximate analysis result indicated that Moringa oleifera had the highest crude protein content of 17.88% while Albizia lebbeck was best in crude fibre content (2.00%). All three tree species recorded no significant difference in dry matter content of 45.08%, 45.00% and 45.63% respectively. These tree species should be encouraged within the farming system of farmer to aid animal production

    Maternal and child health interventions in Nigeria: a systematic review of published studies from 1990 to 2014

    BACKGROUND: Poor maternal and child health indicators have been reported in Nigeria since the 1990s. Many interventions have been instituted to reverse the trend and ensure that Nigeria is on track to achieve the Millennium Development Goals. This systematic review aims at describing and indirectly measuring the effect of the Maternal, Newborn, and Child Health (MNCH) interventions implemented in Nigeria from 1990 to 2014. METHODS: PubMed and ISI Web of Knowledge were searched from 1990 to April 2014 whereas POPLINE® was searched until 16 February 2015 to identify reports of interventions targeting Maternal, Newborn, and Child Health in Nigeria. Narrative and graphical synthesis was done by integrating the results of extracted studies with trends of maternal mortality ratio (MMR) and under five mortality (U5MR) derived from a joint point regression analysis using Nigeria Demographic and Health Survey data (1990-2013). This was supplemented by document analysis of policies, guidelines and strategies of the Federal Ministry of Health developed for Nigeria during the same period. RESULTS: We identified 66 eligible studies from 2,662 studies. Three interventions were deployed nationwide and the remainder at the regional level. Multiple study designs were employed in the enrolled studies: pre- and post-intervention or quasi-experimental (n = 40; 61%); clinical trials (n = 6;9%); cohort study or longitudinal evaluation (n = 3;5%); process/output/outcome evaluation (n = 17;26%). The national MMR shows a consistent reduction (Annual Percentage Change (APC) = -3.10%, 95% CI: -5.20 to -1.00 %) with marked decrease in the slope observed in the period with a cluster of published studies (2004-2014). Fifteen intervention studies specifically targeting under-five children were published during the 24 years of observation. A statistically insignificant downward trend in the U5MR was observed (APC = -1.25%, 95% CI: -4.70 to 2.40%) coinciding with publication of most of the studies and development of MNCH policies. CONCLUSIONS: The development of MNCH policies, implementation and publication of interventions corresponds with the downward trend of maternal and child mortality in Nigeria. This systematic review has also shown that more MNCH intervention research and publications of findings is required to generate local and relevant evidence
