Abstract:The Yellow oleander (Thevetia peruviana), is a potential oil seed and a good alternative source of nutrition for food and animal feeds. The seeds of Yellow oleander from four geographical regions (Busia, Bondo, Thika (JKUAT) and Mombasa districts) in Kenya were subjected to a nutritional value study. The oil and the defatted seed cake were analyzed for food values (fatty acids, proteins, minerals, fibre, and carbohydrates). Fatty acid characterization of the oil was done by GC. Minerals analysis was performed using AAS and flame photometer. The crude protein content of the defatted cake was determined by semi-micro Kjeldahl method. Carbohydrates values were determined by difference. Data analysis was done by SPSS program. The results showed that the nutritional values of these seeds were similar to those of other common oil seeds and did not depend on the climatic regions.

Keywords:  Yellow oleander, food value, plant.

Abstract: There are many situations where human activitieshave significant effects on the environment. Ozone layerdamage is one of them. The objective of this paper is to reviewthe origin, causes, mechanisms and bio effects of ozone layerdepletion as well as the protective measures of this vanishing layer. The chlorofluorocarbon and the halons are potent ozone depletors. One of the main reasons for the widespread concernabout depletion of the ozone layer is the anticipated increase inthe amounts of ultraviolet radiation received at the surface ofthe earth and the effect of this on human health and on the environment. The prospects of ozone recovery remain uncertain. In the absence of other changes, stratospheric ozoneabundances should rise in the future as the halogen loading fallsin response to regulation. However, the future behaviour ofozone will also be affected by the changing atmospheric abundances of methane, nitrous oxide, water vapour, sulphateaerosol, and changing climate.

Abstract: An electrochemical method for the determination of L-Tyrosine (LTY) using a dicyclomine hydrochloride (DICY) polymer film modified carbon paste electrode. The surface morphology of poly (DICY) modified carbon paste electrode was characterized by SEM. The modified electrode showed excellent electro catalytic activity towards the oxidation of LTY in 0.1 M phosphate buffer solution of pH 6.5. The effect of pH, concentration and scan rate were studied at the bare carbon paste electrode and poly (DICY) modified carbon paste electrode were investigated. Increase of LTY concentration shows linear increase in oxidation peak current. The linear relationship was obtained between the anodic peak current (Ipa) and concentration LTY in range 2×10-5 M to 1×10-3 M with correlation coefficient of 0.9984. The low detection limit (LOD) and low quantification limit (LOQ) of LTY were detected. The cyclic voltammetric studies indicated that the oxidation of LTY at the modified electrode surface was irreversible; adsorption controlled and undergoes a one electron transfer process at the poly (DICY) film modified carbon paste electrode. The modified electrode showed high sensitivity, detection limit, high reproducibility, easy preparation and regeneration of the electrode surface.

Abstract: Cobaloxime complexes of the type [CoCl(DMGH)2(L)], where DMGH = dimethylglyoxime monoanion, L =tri-ethanol amine and 1,10 phenanthroline, were synthesized. The compounds were formulated on the basis of cobalt and chloride contents, IR and UV-visible spectral analyses and magnetic moment measurement. Cyclic voltammetric technique was also employed to investigate the interaction between Co(II)and the ligands under study.

Keywords: Cobaloxime, Vitamin B12, Dimethylglyoxime.
