The main aim of this study is to synthesize porous carbon adsorbent from chemical precursor in order to prevent metal impurities that are commonly associated with porous carbon adsorbents derived from agricultural residues. Deferrated kaolinite was used as a template material for the synthesis of porous carbon adsorbent from polyfurfuryl alcohol (PFA). The structural and adsorption characteristics of the adsorbent were investigated using Fourier transform infrared (FT-IR) spectroscopy and methylene blue adsorption. FT-IR spectra showed that calcination of the kaolinite impregnated with polyfurfuryl alcohol, at 500°C ensured carbonization of the polymer (between kaolinite layers) but did not collapse the mineral layer structure which is required for the creation of pores in the templated carbon. Results from the adsorption studies showed that for all the different initial concentrations of the methylene blue, the templated carbon had higher adsorptive capacity than non templated carbon from carbonized free polyfurfuryl alcohol. © Maxwell Scientific Organization, 2011.

This work presents experimental results of a research carried out on lime stabilized lateritic soils using rice husk ash as admixture. The index property tests classified the soils as (A-7-6) under the AASHTO soil classification scheme. Thus, the material is deemed inadequate for use as a road pavement base or sub-base. Index and geotechnical properties tests conducted on the soil containing lime and rice husk ash combinations shows significant improvement in properties. The Atterberg limits were significantly altered with lime and rice husk ash combination; the plasticity of the soils significantly reduced from 18.10 to 6.70 for sample A and 26.6 to 5.92 for sample B at 6 % lime and 12.5% RHA combination. In terms of compaction characteristics, addition of lime and rice husk ash decreased the maximum dry density and increased the optimum moisture content. At 8% lime and 12.5% RHA, the values of MDD for samples A and B are 1.27 and 1.22 Mg/m3 respectively. The California Bearing Ratio (CBR) values peaked at 50%unsoaked values for 8 % lime and 10 % RHA combinations for sample A while that of sample B was 30% at 6% lime and 12.5% RHA combinations. The values do not meet the requirement for good quality base or sub-base pavement materials for major or urban roads. Stabilized sample A however suffices for use as road-base and subbase for lightly trafficked minor roads (CBR ≥45% for minor road). © 2011 ejge. Source

Various nutrients in Vitis vinifera (Grape) grown in Bomo village, Zaria were analyzed. These include carbohydrate, lipids, Moisture Fibre, Ash, proteins and Minerals such as Ca, Fe, Cd. The Macro-Kjeldhal method was used for protein determination, soxhlet extraction for fat and Atomic Absorption Spectrophotometer for mineral element determination. Anti-Nutrients determined were Oxalate, Phytic Acid and Cyanogenic Glycosides. The result showed that moisture content was 81.50%, lipid 0.18 and 0.44% ppm for calcium. The concentration of the anti-nutrient agreed with the WHO standard which was not harmful enough to prevent consumption of the fruit. © Maxwell Scientific Organization, 2012. Source

A parabolic solar cooker was designed to cook four different types of common food stuffs (White rice, Parboiled rice, Beans and Yam), characterized the food items and to reduce continuous reliance on conventional source of energy for cooking. The test performance of the solar cooker was carried outin Bauchi, North-East, Nigeria to ascertain the level of its performance when it was place under the sun and positioned and position in the east-west orientation at a slope of 10.3°. The research revealed that 1 kg of white rice was completely cooked in 1 hour 15 minutes at an average beam radiation of 623W/m2 after attaining maximum temperature of 368K under clear weather condition. Parboiled rice of 1 kg was completely cooked in 1 hour 15minutes at the same average beam radiation of 623W/m2 after attaining maximum temperature of 367K. Beans of 1 kg was cooked at an average beam radiation of 536.5W/m2 in 1 hour 30minutes at an average wind speed of 0.5m/s, and Yam of 1.1kg was cooked in just 1 hour 30 minutes at very low beam radiation of 430.1 W/m2. The highest temperature reached for this test was 364K. It was established that this type of parabolic solar cooker can comfortably cooked these varieties of our local dishes within the range of 1 hour to 1 hour 30minutes under clear weather condition in the Bauchi, north-east of Nigeria. In view of the significance of this research and looking at the cost of energy in the developing nations, the researchers are convince that the parabolic solar cooker is an answer to the perennial energy needs facing the poor and will also go a long way in reducing the cost of energy particularly amongst local and urban dwellers in Nigeria. © 2015 IEEE.

The aim of the study is to investigate the efficacy of Di-n-octyl phthalate isolated from Ceiba pentandra leaves extract for its anti Echis ocellatus venom properties. The leaves of Ceiba pentandra was extracted with aqueous methanol, partitioned on column chromatography and subjected to TLC and preparative TLC. The isolate was tested for its anti venom activity and submitted to IR and GCMS for structural elucidation. Our findings revealed that the isolate was biologically active in inhibiting PLA 2 activity in a dose dependent manner. The IR analysis showed that the isolate has a carbonyl functional group and aromatic ring and the GCMS analysis revealed that the compound isolated was Di-n-octyl phthalate with molecular weight 391. The inhibitor (Di-n-octyl phthalate) isolated during this research might become a highly effective therapeutic agent for the reducing of snake bite envenomation. The relevance of these findings would be of importance in the area of development of anti snake bite drugs that are going to be effective, cheap, accessible and less allergic plant compound that can be scientifically explored. © Maxwell Scientific Organization, 2012.
