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 texture. ...

Soil contaminated with heavy metals from agricultural and industrial sources leads to unhealthy food. The metals enter the food chain and are consumed by humans. Phosphate fertilizers too contain undetermined amounts of ...

The metal-oxide-semiconductor field-effect transistor (MOSFET) is a transistor used for amplifying and switching on circuits. In this study, the MOSFET parameters were computationally modeled, analysed and presented. The ...

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 ...

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 ...

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 ...

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 ...

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 ...
