Optimization of microwave-assisted biodiesel production from watermelon seeds oil using thermally modified kwale anthill mud as base catalyst.

A heterogeneous catalyst was developed from raw Kwale red Anthill mud by thermal treatment in a muffle furnace at 900 °C for 4 h. The resulting heterogeneous catalyst was highly porous with a surface area of 42.16m/g, possessing excellent stability as well as high catalytic activity.

Quantification and health impact assessment of polycyclic aromatic hydrocarbons (PAHs) emissions from crop residue combustion.

Emission of Polycyclic Aromatic Hydrocarbon compounds from combustion of crop residue was investigated. Crop residues comprising maize cobs, maize husks, rice husks and bean chaff were burnt in a furnace at a temperature of 400 °C and the emissions from the combustion process were characterized using standard methods. Health risk through inhalation was assessed using toxic equivalent factors and excess lifetime cancer risk.

Optimization of biogas yield from anaerobic co-digestion of corn-chaff and cow dung digestate: RSM and python approach.

The utilization of various feedstocks of unique characteristics in producing biogas could potentially enhance the application of clean fuel from biomass wastes. Two modelling tools were used to explore biogas production from plant and animal wastes. In this study, corn chaff was inoculated with cow dung digestate using different mixing ratios of substrate/inoculum (S/I) of 1:1, 1:1.

Physicochemical equivalence evaluation of some piroxicam capsule brands in Nigeria.

Comparative chemical and pharmaceutical equivalence study on ten brands of piroxicam capsules was carried out. The aim of the study was to determine whether the brands are comparable with each other on the basis of their physico-chemical properties. The chemical and pharmaceutical equivalences of ten brands of piroxicam capsules were assessed by evaluating the uniformity of weight, dissolution rate, content identification and the chemical assay of the capsules.

Functional insulin receptors on human epithelial ovarian carcinoma cells: implications for IGF-II mitogenic signaling.

The insulin receptor mediates a proliferative response in certain transformed cells, but little is known about its function in ovarian cancer. We used human epithelial ovarian carcinoma cell lines and lifespan-extended normal ovarian surface epithelial (OSE) cells to examine (125)I-insulin binding and mitogenic responses to insulin. All cancer cell and OSE cultures specifically bound (125)I-insulin.
