Mimosa pigra has been identified as a serious invasive alien plant that has invaded the floodplain of Lochinvar National Park in the Kafue flats. There has been a challenge in finding an effective method to successfully control Mimosa pigra. This is because when Mimosa pigra is cut, it...

This dissertation considers the single quantum pair annihilation of positrons with bound K-shell electrons in heavy atoms. It gives numerical calculations of the total cross section. By means of the method due to Basbas et a/.14, the binding-energy effect and its contribution to SQA cross...

The ordinary time-independent Landau problem of a charged particle moving in an external perpendicular homogeneous magnetic field and the case of when a linear potential is introduced are reviewed for motion occurring in an infinite plane, on an infinite strip and in the half-plane. The first...

The work presented here is a survey of some known results in functional analysis, particularly in the field of Operator theory. The study begins with definitions of linear spaces and some topological results which form the necessary background.Chapter two is the heart of the work and deals with...

This study compares, explains and analyses variations in attitudes towards desired number of children amonr, uanen in three locslities in Chieftainess Myanje's area, Eastern Province, Zambia.This involves analysis of a variety of variables which previous studies suggest may influence the number...

This study investigated intersexual differences in spatial ability amongst Zambian children aged between five and eighteen years. The results were viewed in the light of cross-cultural research. Particular attention "as paid to the concept of field dependence. It was found that intersexual...

Laminar stability flow for incompressible fluid flow in two dimensional symmetric channels of variable width is reviewed through a survey of various related topics, Many authors whose works are reviewed here investigated linear stability using the "WKB' method in which regions of growth of a...

Zambia, where annual rainfall is moderate to meagre over large parts of the country, and year to year variations are large, unpredictable weather can prove to be a serious obstacle to stable and systematic agricultural production. For effective agricultural planning on a rational and scientific...
