A novel silica coated paper substrate is developed through a facile vacuum filtration method by using the commercially available silica particles as the coating material and corn starch as the adhesive agent. Unlike the commercial silica coated paper (namely grade SG81 paper), the resulting paper substrate was covered by a layer of silica particles on the top side of the paper, and no cellulosi...

In short-term-experiments [14C]-labelled malonic acid, stearic acid and acetate have been incorporated into leaf fatty acids of seedlings of Cucumis sativus, Hordeum vulgare and Zea mays. The pattern of labelled fatty acids changed markedly by treatment with the chloroacetamide herbicides metazachlor, metolachlor or butachlor. During a 2-h incubation time, 1 μm chloroacetamide specifically inhi...

Field trials were conducted in savannah woodland (Njala) and rainforest (Serabu) agroclimatic regions of Sierra Leone during 2016 second cropping season to assess different preemergence herbicides techniques that is efficient, cost effective environmentally safe cowpea production. The experiment consisted 20 treatments which included 2 genotypes (slipea 4 slipea 5) 10 weed control viz: butachlo...

An obligate anaerobic bacterial strain (BAD-6T) capable of degrading acetochlor and butachlor was isolated from an acetochlor-degrading reactor. Cells were Gram-stain positive, straight to gently curved rods with flagella. The major fermentation products in peptone-yeast broth acetate butyrate. optimum temperature pH for growth 30 °C 7.2–7.5, respectively. cellular fatty acids (> 10%) C14:0 FAM...

This is a case of a 22-year-old Hispanic male with a history of bipolar disorder and methamphetamine dependence who was admitted after presenting with suicidal ideations by slashing his throat with a machete. The patient had been smoking and inhaling "processed" pyrethroid for about eight weeks as an inexpensive methamphetamine substitute. He reported experiencing a "rush" similar to methamphet...
