Effects of zeolites X and Y on the degradation of malathion in water
(Science Publishing Group, 2013-04)
The inclusion of both zeolites X and zeolite Y significantly affected the dissipation of malathion in water. In the fresh water, malathion degradation followed a pseudo-first order kinetics with concomitant half-life ...
NUTRITIONAL COMPOSITION OF THE PUMPKIN (Cucurbita spp.) SEED CULTIVATED FROM SELECTED REGIONS IN KENYA
(2013)
Cucurbita is one of the underutilized crops and its existence in Kenya is presently threatened due to neglect. The pumpkin is a rich source of nutrients and has medicinal properties. However, owing to the perception that ...
Environmental Communication: A Review of Information Sources and Communication Channels for Enhanced Community-Based Natural Resource Management in the Greater Mara Region of Kenya
(Sage Publications, 2013)
The Mara-Serengeti is an ecosystem of immense importance to both Kenya and Tanzania, contributing significantly to the economies of both countries and forming a rich biodiversity reservoir. This ecosystem is among the most ...
Effects of Zeolite X on Dissipation of Hexazinone from Agricultural Waste Waters in Western Kenya
(2013-10)
Dissipation of hexazinone in Zeolite X treated wastewater followed pseudo first-order kinetics giving a calculated half-life of 41 days compared to a half-life of 144 days in untreated wastewater. The herbicide degraded ...
Beneficiation of Iron in Thermal-Reduced Ilmenite by Magnetic Separation
(2013)
Increasing demands for Iron in countries development, and lack of conventional reducing agents has resulted into sourcing of alternative ways of beneficiating the iron ore. This paper reports on the study that was done to ...
THE ROLE ON GENDER POLICY IN „SCALING UP‟ GIRLS „ACCESS TO SECONDARY SCHOOL EDUCATION IN KENYA
(International Journal of Disaster Management and Risk Reduction, 2013)
The Kenya government‟s commitment to increase girls‟ participation, retention, transition and completion at secondary school level is well documented in official government documents. It is also part of the Governments ...
Effects of Faujasite X and Y Zeolites on the 1,1,1-Trichloro-2,2? bis(p-chlorophenyl)ethane (DDT) Degradation during Water Purification
(Science Publishing Group, 2013-06)
The ability of zeolites to abstract and denature organochloride pesticides finds application in water purification practices. In this study, activated faujasite X and Y zeolites were separately exposed to 1, 2 and 4 ppm ...
FACTORIZATION OF LARGE COMPOSITE INTEGER
(International Journal of Mathematics and Statistics Studies, 2013)
In this paper we practically deal with the problem of factorizing large integers. The various
algorithms that have been proposed are not efficient that is they do not run in polynomial time. We use
the algebraic approach ...
Synthesis, Antiplasmodial Activity, and β‑Hematin Inhibition of Hydroxypyridone−Chloroquine Hybrids
(American Chemical Society, 2013)
A series of noncytotoxic 4-aminoquinoline-3-hydroxypyridin-
4-one hybrids were synthesized on the basis of a synergistic in vitro
combination of a precursor N-alkyl-3-hydroxypyridin-4-one with chloroquine
(CQ) and tested ...
Nitrogen-Doped Carbon Nanotubes Synthesised by Pyrolysis of (4-{[(Pyridine-4-yl)methylidene]amino}phenyl)ferrocene
(Hindawi Publishing Corporation, 2013-08-13)
Nitrogen-doped carbon nanotubes (N-CNTs) were synthesized by pyrolysis of (4-{[(pyridine-4-yl)methylidene]amino}phenyl) ferrocene in a solution of either acetonitrile or toluene as carbon source. This was achieved by testing ...
