The teenage period is between 12 and 19 years. Pregnancy in the teenager poses special social, psycological and medical risks both to the mother and her offsping. Because of the physical, physiological and emotional immaturity of the adolescent period, pregnant teenagers are prone to developing...

_ Let * be a root system in a £-dimensional real Euclidean space V with Weyl group W( £), and let W+{<f) denote its rotation subgroup. In [173 » the projective representations of the rotation subgroup W ( 9) have been determined from those of W( $) for each root system $. This is done by...

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,...

Improving food security by increasing crop production is currently Zambia's primary objective. Poor soil fertility and inadequate utilization of chemical fertilizers have often resulted in poor crop yields and that has exacerbated the problems of poverty and hunger in the country. Phosphorus is...

A two-year prospective study of Flexor Tendon repair at the University Teaching Hospital (UTH), Lusaka is presented. A total of 20 cases were seen in this period, with a total of 71 tendon repairs. Results were graded using the white (1956) and Boyes (1947) criteria: 4 patients were graded as...

The rate of caesarean section has been increasing in the last fifty years. A previous caesarean section has also steadily become a leading indication to perform a caesarean section. With the realization that caesarean section has got its own risks, and the strain on medical costs, the strategy...

The Study was conducted at the University Teaching Hospital (UTH), chest clinic. The purpose of the study was to find out the outcome of tuberculosis treatment in Sputum Positive Patients after eight months anti-tuberculosis treatment. Observation and literature review has shown that there has...

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...
