INVESTIGATION OF POLLUTANT LEVELS AND EFFICIENCY OF HEAVY
(2016-05-19)
An increase in population initiating rapid industrialization has been found to consequently increase the effluents and domestic wastewater into the aquatic system. This has resulted in heavy metal pollution which has become ...
ROTATING OPTICAL BEAMS: DIGITAL HOLOGRAPHIC GENERATION, PROPERTIES AND SELF-RECONSTRUCTION DYNAMICS
(2016-05-19)
This thesis reports on an experimental investigation of rotating optical beams. Superpositions of higher-order Bessel beams with rotating intensity profiles were generated using a digital holographic experimental technique ...
OPTICAL NOISE PERFORMANCE IN SMF-REACH AND SMF-REDUCED SLOPE FOR RAMAN FIBRE AMPLIFICATION USING DIFFERENT PUMPING TECHNIQUES
(2016-05-19)
Signal amplification in optical fibres during transmission has become one of the techniques in improving capacity and reach in telecommunication networks. Fibre Raman amplifiers (FRAs) are currently being adopted in many ...
ALGEBRA OF COUPLED ELECTRONS IN THE CO-EXISTENCE OF
(2016-05-19)
Superconductivity is a phenomenon in which the d.c electrical resistance of a material vanishes completely and instantly rather than gradually when it is cooled below a certain temperature called the superconducting ...
E-OPTIMAL DESIGNS FOR SECOND-DEGREE KRONECKER
(2016-05-19)
Many products are formed by mixing together two or more ingredients. For example, in
building construction, concrete is formed by mixing sand, water and cement. Many
practical problems are associated with investigation ...
FIRST PRINCIPLES ELECTRONIC STRUCTURE CALCULATIONS OF BaF2 AND GENERATION OF PARAMETRIZED POTENTIAL FOR MOLECULAR DYNAMICS STUDY OF THE SUPERIONIC PROPERTIES OF c-BaF2
(2016-05-19)
The electronic structure and defects of barium fluoride, BaF2, have been studied using the denstiy functional theory, DFT and density functional perturbation theory, DFPT. Lattice parameter of 6.10 Å was calculated comparable ...
FABRICATION AND CALIBRATION OF LOW COST CAPACITIVE SOIL
(2016-05-19)
ABSTRACT
Soil humidity is critical in crop production and its control is essential to water conservation. The knowledge of soil humidity to majority of farmers in Kenya is based on effects of weather on crops and soil ...
A DENSITY FUNCTIONAL THEORY STUDY OF COPPER OXIDES NANOWIRES AND CLUSTERS ON ANATASE TiO2 (101) SURFACE FOR PHOTOCATALYTIC WATER SPLITTING
(2018)
Copper oxides deposited at titania surfaces have a beneficial effect on the photocatalytic
activity of TiO2, particularly water splitting. However, the role of copper oxides and mechanisms of enhancement remains to be ...
SYNTHESIS, GROWTH AND PHYSICO-CHEMICAL PROPERTIES OF TITANIUM DIOXIDE NANOTUBES FOR PHOTOCATALYTIC WATER PURIFICATION
(2018)
Titanium dioxide (TiO2) photocatalysis is a promising method for decomposition of
organic contaminants in water and belong to new a class of water purification
methods called advanced oxidation processes (AOPs). AOPs ...
Modified Phenomenological Formula for the Ground State Energy of Light Nuclei
(World Scientific News, 2019)
A modified phenomenological formula for the ground state binding energy in the region of light nuclei is proposed. Since binding energy is proportional to the volume of a nuclide, the new formula contains a volume term ...
