APPLICATION OF THE JOINT MODELLING OF SERIAL ANTHROPOMETRIC MEASURES AND MORTALITY AMONGST CHILDREN FOLLOWING HOSPITALIZATION WITH A COINCIDENT ACUTE INFECTIOUS DISEASE IN ADDITION TO SEVERE ACUTE MALNUTRITION
(Pwani Unversity, 2016-08-08)Background: Malnutrition continues to be a major health burden in developing countries. It is globally the most important risk factor for illness and death, with hundreds of millions of young children particularly affected. ... -
CHARACTERIZATION OF IONOSPHERIC DYNAMICS OVER THE EAST AFRICAN DIP EQUATORIAL REGION USING GPS-DERIVED TOTAL ELECTRON CONTENT.
(2015-03-18)The structure of electron density in the ionosphere and ionospheric irregularities can be monitored using Global Position System (GPS) in near real time. Compared to other observation techniques, GPS satellites offers a ... -
THE EFFECT OF HERMANSON’S SPATIAL DIELECTRIC FUNCTION ON THE DENSITY OF IMPURITY STATES IN A GALLIUM ARSENIDE QUANTUM DOT (GaAs QD) OF RECTANGULAR CROSS-SECTION
(Pwani Unversity, 2018-04-08)In this work, a theoretical study of the effect of Hermansons dielectric function (screening) on the density of impurity states (DOIS) of a donor impurity located in the center of a Gallium Arsenide (GaAs) Quantum Well Dot ... -
MECHANICAL AND OPTO - ELECTRICAL CHARACTERIZATION OF CHITOSAN - A MARINE BASED BIOMATERIAL
(Pwani University, 2016-07)Mechanical, electrical and optical properties of chitosan thin films extracted from the squid gladius found along the coastal areas of Kilifi and Mombasa were investigated in this study. The films were prepared by the ... -
SYNTHESIS AND CHARACTERIZATION OF ZINC OXIDE/REDUCED GRAPHENE OXIDE (ZnO/RGO) NANOMATERIAL FOR BIOSENSOR APPLICATIONS
(Pwani University, 2023-01-21)Advances towards the nano and femto scale have been the core for improving the operation efficiencies for biosensors. However, there still exists a mismatch in understanding the correlation between these advances and the ... -
THE VARIATION OF PHOTOIONIZATION CROSS-SECTION WITH INCIDENT PHOTON FREQUENCY AND WITH POSITION OF A DONOR IMPURITY IN A QUANTUM WELL DOT OF SQUARE CROSS-SECTION USING A VARIATIONAL TECHNIQUE
(Pwani Unversity, 2018-04-08)In the present work, we carried out a theoretical study of the variation of the photoionization cross-section with the position of a hydrogenic donor impurity along the growth axis of a square GaAs quantum well dot. In our ...
