Saeed [11] has considered Schur multipliers of some of the finite abelian groups.The study of the schur multipliers of abelian groups is the first step in the studying of the projective representations of such groups. Our objective here is to determine the Inequivalent Irreducible projective...

Bulk Hetero-Junction - (BHJ) - Organic photovoltaic (OPV) cells based on the conjugated polymer poly (3-hexylthiophene-2, 5- diyl) (region-P3HT) also referred to as P3HT and a fullerene derivative [6, 6] Phenyl-C61-butyric acid methyl ester (C60-PCBM) also referred to as PCBM. The optimization,...

A high absorptance (>0.90) is an essential factor in the efficient use of a .solar collector. However, equally important is the need to keep the emittance as low as possible (<0.20). Both the.absoptance and emittance depend on the optical properties of the coating and the substrate. The solar...

Banana (Musa spp.) is an important food crop of the humid tropical lowland areas of the world. Banana production is beset by several problems, related to crop husbandry, selection of planting material, soils, diseases, and pests. Although more than 25 borers have been recorded on banana, the...

The study focused on the perceptions and socioeconomic repercussions of irrigating vegetables using treated wastewater in Garden Compound in Lusaka. This qualitative study was based on stratified sample population of forty (40) comprising wastewater vegetable irrigators and non wastewater...

Many physical problems are studied through mathematical equations especially differential equations. For example, problems in mechanics, electricity, aerodynamics, to mention just a few, use differential equations. While it is true to say that physical sciences and tech¬nology are the two main...

A cross-sectional study was conducted in Lusaka Province of Zambia to estimate brucellosis seroprevalence and identify associated risk factors. This study was done between January 2007 and February 2008 in commercial cattle farms in 3 districts of Lusaka Province (Kafue, Chongwe and Lusaka...

This dissertation is a study of the prospects and challenges of gender mainstreaming in water sector policies or policies that have influenced operations of the MEWD/DWA mainly the Gender Policy (2000) and the National Water Policies (1994 and 2010) and their implications for gender actions to be...
