A procedure for preparation of semi-activated carbon fiber (SACF) without any treatment under high temperature was proposed. The first step of the procedure is coating of an inorganic fiber (E-glass fiber) by an adsorbent mixture including powder activated carbon, methyl cellulose and water. In this work a set of experiments was performed to attain appropriate adsorbent mixture for good quality...

Background: This study investigated the protective effects of aqueous extracts of Anogeissus leiocarpus (DC) Guill & Perr (Combretaceae) and Terminalia avicennioides Guill & Perr (Combretaceae) root barks, as well as their 1:1 (w/w) mixture on liver redox and haematological parameters of diethylnitrosamine-treated rats. Methods: Rats were orally administered distilled water, diethylnitrosami...

6-methyl- 1,2,4-triazine-3-(2h)-selenone-5(4h)-one(l) reacts in the presence of base with phenacyl bromide to give a mixture of compounds (2) and (3). this mixture is dehydrated in the presence of h,so, to give 3-phenyl-6 methyl-7h-selenazolo[3,2-b] [i ,2,4] triazin-7-one (6). for careful structure assignment of (6) its regioisomer 3-methyl-6-phenyl-4h-selenazolo [2,3-c] [ 1,2,4] triazin-4-one ...

sod culture is one of the important methods in establishing and repairing of turf grass, especially in sport fields. nowadays, a mixture of sand and peat are commonly used in sod production in iran. because peat media is expensive, it seems necessary to find an alternative medium. rice hull, tea waste and leaf compost as economical organic material that are available in huge loads in north of i...
