Production of biodegradable grease from Atili (Blackdate) oil

MAINA N. S^*, Israel J. J

The work was aimed at the production of biodegradable grease from Atili (Blackdate) Oil that will be environmentally friendly. The grease was produced by mixing and blending of the base oil (Atili oil) with a mixture of calcium hydroxide and the stearic acid at 90oC which was then slowly heated to 190oC for about three hours to obtain the desired product. Three sets of the grease were produced ...

Study on the Thermal Properties of Epoxy Resin Reinforced with Arylidene-based Polybenzoxazine

Abdulrahman Musa^*, Hamza A., Muhammad Abubakar Lawal

In this study, a new bis-arylidene derived benzoxazine: 2,6-bis((3-(2-hydroxyethyl)-3,4-dihydro-2H-benzo[e]  [1,3]oxazin-6-yl)methylene)cyclohexanone (HEB) was synthesized from its precursor: 2,6-bis(4 hydroxybenzylidene)cyclohexanone (BCH). The BCH was obtained as an aldocondensation product of cyclo hexanone and 4-hydroxybenzaldehyde, in an acid catalysed organic medium. Both HEB and BCH were ch...

Investigating Patients` Education on the Role of Footwear in Diabetic Foot-Care

TAGANG J. I^*, Chen R. C

There is evidence that appropriate footwear plays pivoted role in the management of diabetic foot problems and inappropriate footwear causes foot ulceration. Therefore, this work was aimed at investigating how footwear could be used to prevent or reduce diabetic foot problem. Structured questionnaires were designed and used to gather information from diabetic patients. The study was carried out...

Synthesis and application of vinylsulphone disperse reactive dyes derived from pyridone derivatives on polyester fabric

Fasansi I.^*, Kasali A. B.

Vinylsulphone disperse reactive dyes were synthesized by diazotizing 2-methoxy-5-methyl-4- (sulfatoethylsulfonyl) aniline and coupling with substituted pyridone derivatives. The synthesized dyes were applied successfully on polyester without dispersing agent and the dyeing showed good leveling and build up with desired colour yield. The dyeing was dependent on the pH and the optimum pH was foun...

Some clinical applications of nanotechnology

GIWA F J^*, ILIYA E. B

Nanomedicine can be succinctly defined as the application of nanotechnologies in a healthcare setting. Nanomedicine ascends from the integration of different sciences; physics, chemistry, biology, materials science, engineering, using the nanometer scale. This leads to scientists with different backgrounds, and diversified technical and intellectual skills, trying to address medical problems us...

Treatment of waste water by activated carbon developed from Borassus aethiopum

Jacob A. G^*, OKUNOLA O. J, UDUMA A. U

The use and effectiveness of granular and powdered activated carbon made from Borassus aethiopum shells in adsorption studies were investigated. The source material was carbonized at 5000C and for a residence time of three hour in a muffle furnace, while 0.5M each of H3PO4 and ZnCl2 were used for chemical activation at 7500C and for 60m residence time. The adsorption of lead from aqueous solut...
