EFFECT OF LIMING ON LEVELS OF POLLUTANT HEAVY METALS IN
(2016-05-23)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 ... -
DETERMINATION OF SELECTED HEAVY METALS POLLUTANTS AND
(2016-05-23)The study set out to evaluate the effect of industrial activities by analyzing selected heavy metals and physicochemical parameters of water. Chemical survey was conducted in 9 selected sites (potential polluting sites) ... -
DIFFUSION OF ASPIRIN-(ACETYLSALICYLIC ACID) BASED DRUGSIN SODIUM HYDROXIDE SOLUTION AT 25C
(2016-05-23)Diffusion is a macroscopic motion of components of a system that arises from concentration difference and plays a vital role in drug migration in the bodygoverned by Fickian diffusion laws. This project considers effective ... -
ISOLATION AND CHARACTERIZATION OF ACTIVE ANTIHYPERGLYCEMIC COMPONENT OF URTICA DIOICA LEAVES
(2016-05-20)Urtica dioica (U.dioica) commonly known as the stinging nettle is a herbaceous perennial plant belonging to the plant family Urticaceae. The aqueous extract of the plant have been shown to have antihyperglycemic activity ... -
DETERMINATION OF DIFFUSION COEFFICIENTS OF FOOD
(2016-05-20)Food additives play a vital role in today’s bountiful and nutritious food supply and their transportation in water is a diffusion process governed by Fickian diffusion laws. The study looks into the rate of diffusion of ... -
HEAVY METALS, PHOSPHATES AND NITRATES LEVELS IN VEGETABLES: A CASE STUDY OF KITALE MUNICIPALITY, TRANS-NZOIA COUNTY, KENYA
(2016-05-20)Effluents released from sewage treatment plant contain toxic metal pollutants whose uptake by vegetables is governed by their availability and concentration in the soil. Therefore such vegetables may accumulate pollutants ... -
SYNTHESIS OF A PHENYLETHYLTHIOUREA DERIVATIVE AS A POTENTIAL NON-NUCLEOSIDE INHIBITOR OF HIV-1 REVERSE TRANSCRIPTASE
(2016-05-20)The emergence of resistant strains of HIV-1 towards existing drugs has prompted a search for new compounds with good antiviral activity and favourable toxicological profile. This work reports the synthesis of a PETT ... -

CHARACTERISATION, ANTIFUNGAL AND MOSQUITOCIDAL ACTIVITIES OF MORMODICA FOETIDA LEAF EXTRACTS AND THEIR FORMULATION INTO DROP PILLS.
(2016-05-20)The upsurge in the prevalence of resistance to many synthetic antifungal agents and incidence of multidrug resistant mosquito-borne diseases has spurred scientists to research for new plant-based antifungal and mosquitocidal ... -
POLLUTANT LEVELS IN WASTE WATER FROM TANNERY EFFLUENT: A
(2016-05-19)Wastewater from leather processing industries is very complex and leads to water pollution if discharged before treatment, especially due to its high organic loading and chromium content. Over the past years, Nakuru Tanners ... -
SYNTHESIS, SPECTRAL AND ELECTROCHEMICAL STUDIES OF
(2016-05-19)In this thesis, the synthesis, characterization and electrochemical studies of monometallic and bimetallic complexes of schiff base ligands have been undertaken. Synthesis of bimetallic complexes initially involved preparation ... -
SPATIAL AND TEMPORAL VARIATIONS IN PHYSICO-CHEMICAL
(2016-05-19)Increased human activities have led to water pollution, especially metals and nutrients. Therefore, prudent management of aquatic environments require information on their quality status that can be estimated by monitoring ... -
SYNTHESIS, CHARACTERIZATION OF ZnO NANO PHOTOCATALYSTS AND THEIR APPLICATION IN PHOTOREMEDIATION OF WASTE WATER
(2016-05-19)Water scarcity and its contamination with toxic metal ions and organic dyes represent a serious worldwide problem in the 21stcentury. Today’s world faces alarming challenges in the rising demand for drinking water and ...
