Low Cost Pozzolana based Cement from Industrial and Agricultural Waste Materials

Wachira, Jackson M. (Kenyatta University, 2003-09)

This thesis reports the results of a study aimed at making low cost cement from some agricultural and industrial wastes. The utilization of these wastes would avail an economical and environmentally friendlier waste ...
Preparation and Properties of Long Afterglow CaAl2O4 Phosphors Activated by Rare Earth Metal Ions

Wako, Ali Halake (University of the Free State Republic of South Africa, 2011-11)

This work comprises of several aspects of calcium-aluminate phosphor activated with rare earth metal ions i.e. (CaAl2O4:Eu2+, Nd3+, and Dy3+). In particular the luminescent and structural properties of the long afterglow ...
Structure and Biomass Accumulation of Natural Mangrove Forest at Gazi Bay, Kenya

Githaiga, Michael N. (Kenyatta University, 2013-08)

Mangroves occupy only 0.4% of forested areas globally but are among the most productive ecosystems on earth. They account for about 11% of the total input of terrestrial carbon into the oceans. The above ground carbon ...
Microplastic Abundance, Composition and Distribution in the Endorheic Lake Naivasha, Kenya

Migwi, Francis Kigera (University of Embu, 2020-10-28)

Plastic pollution has recently gained global concern due to the negative effect it presents on both the environment and human health. In the environment, plastics degrade yielding millions of micro- and nano-scale plastic ...
EFFECTS OF TEMPERATURE, DEFECT, AND ph ON PROPERTIES OF caal2o4: Eu2+, Dy3+ PHOSPHOR FOR LIGHTING APPLICATION

Unknown author (Samuel Ndung’u Waithira, 2024-08)

Electricity is the main source of energy used for lighting but still worldwide, a population of about 1.4 billion does not have any access to electricity, with 85 % of them coming from rural areas. Most of the people in ...
Harnessing the nutraceutical properties, Microbial composition of scarabaeoid beetle Larvae and antibacterial compounds of its Endozoic fungus (aspergillus welwitschia)

MWANZA, SYLVIAH SYOMBUA (Sylviah Syombua Mwanza, 2024-08)

The systematic development of antibiotic resistance poses huge worldwide health challenges, specifically in low- and middle- income countries (LMICs) increasing the treatment costs. There is heightened need to broaden the ...
Solid-Liquid Extraction of Heavy Metals in Aqueous Solutions using Chelating Ligands Anchored on Solid Supports

Unknown author (Ian Tharau Kabogo, 2024-08)

The rapid surge of population growth has translated to an unprecedented increase in heavy metal pollution in the environment resulting from various anthropogenic activities. Their non-biodegradable nature, toxicity and ...
