The speciation of copper and zinc in the incineration fly ash of a municipal solid waste in Taiwan was investigated in the present work. By the least-squares fitted X-ray absorption near edge structural (XANES) spectroscopy, we found that CuCO3, CuOH2, and CuO (fractions of 0.09, 0.39 and 0.51, respectively) were the main copper species in the fly ash. Quantitative analysis of the extended X-ra...

Wheat is the world's second most produced grain because of its high consumption rate, easy growth, multipurpose use and important role in the human diet. Every year, abundant amounts of wheat hull are obtained after shell process of the wheat as a waste material. Wheat hull, a by-product of the food industry, has low economic value. The utilization of wheat hull ash in various areas of industry...

The response surface methodology and central composite rotatable design for K=3 was used to study the combined effect of blanching, soaking and sodium hexametaphosphate salt concentration on moisture, ash, leached solids, phytates, tannins and hardness of bambara groundnut during canning. Regression models were developed to predict the effects of the processing parameters on the studied indices...

The purpose of this work was to elucidate the repercussion of changing pH, incubation time and As(V) competition on fluoride (F-) sorption on forest and vineyard soil samples, pyritic, and granitic materials, as well as on the by-products pine sawdust, oak wood ash, mussel shell ash, fine and coarse mussel shell, and slate processing waste fines. To reach this end, the methodological approach w...

To develop a sustainable concrete solution, the aggregates and cement in mixture were partially replaced with Cocos nucifera endocarp (coconut shell) aggregate biomass ash (sugarcane bagasse ash) respectively. The fresh hardened properties studied for three types of mixes (i) mix 10-30% replacement (BA), (ii) Bagasse scrap steel fiber 10 - 50% coconut shell aggregate. property is positively inf...

Chlorotic ringspots or chlorotic leaf specking, terminal bud necrosis, axillary shoot proliferation and severe stunting of groundnut (Arachis hypogaea) were shown to be caused by tomato spotted wilt virus (TSWV). Cowpea (Vigna unguiculata cv. C-152) was found to be a good assay host. TSWV remained infective in buffered sap of groundnut at a dilution of 10-2’5, after storage for 4 h at room temp...

Sesame and groundnut are important crops and a source of edible oil and protein. Amino acid content of both meals was analyzed and studies made on the protein solubility of defatted sesame and groundnut meal in aqueous solution over various pH and in various salt solutions. Valine, isoleucine, arginine, aspartic acid and glutamine were present in high concentration in both the defatted meals. A...

Groundnut or peanut (Arachis hypogaea L.) is one of the important economic oilseed crops of the world. The cultivated groundnut belongs to family Fabaceae, subfamily Papilionaceae. Groundnut is grown in nearly 100 countries. It occupies 21.7 million ha worldwide with a total production of 38.6 million tonnes during 2011 (FAOSTAT, 2011). Among the soil-borne fungal diseases of groundnut, stem ro...

Aiming to investigate the efficacy of different materials as bio-sorbents for the purification of As-polluted waters, batch-type experiments were employed to study As(V) sorption and desorption on oak ash, pine bark, hemp waste, mussel shell, pyritic material, and soil samples, as a function of the As(V) concentration added. Pyritic material and oak ash showed high sorption (90% and >87%) and l...

Seed is the basic input in agriculture. The quality of seed used by farmers determines the status of agriculture they practice. However, for maximum gain in productivity the use of both improved varieties and improved integrated crop management practices are required. Not only do they contribute to increasing productivity individually, but they also act synergistically. Seed of improved varieti...
