We evaluated the effectiveness of Selenite Cystine (SC), Tetrathionate Brilliant Green (TBG) and Rappaport Vassiliadis (RV) broths for Salmonella isolation. We also tested three classic plating media, SalmonellaShigella Agar (SS), Brilliant Green Agar (BGA), Xylose Lysine Desoxycholate Agar (XLD) and two chromogenic agars, Rambach (RA) and CHROMagar Salmonella (CAS). Among 100 poultry carcasses...

in this researchsaccharomyces cerevisiae (baker’s yeast) was used as a cheap, readily accessible, selective, efficient, and green bio-catalyst in a chemo selective reduction of carbonyl group to hydroxyl group. in this green procedure three substrates e.g. (3-(3-nitrophenyl)aziridin-2-yl)-1-phenyl-methanone, pyruvate ester, and 2-acetyl-γ-butyrolactone were reduced to their corresponding reduce...

In this work, an eco-friendly procedure for the preparation of 2,3-dihydroquinazoline-4(1H)-ones was developed by condensation reaction of benzylic and heterocyclic aldehydes with 2-aminobenzamide in the presence of catalytic amounts of cyanuric chloride (2,4,6-trichloro-1,3,5-triazin) as an available and inexpensive organo-catalyst under aqueous media as a green conditions. The new co...

A green and convenient méthode for the synthesis of  a variety of xanthene derivatives by condensation reaction between aldehydes and β-naphthol or dimedone in an micellar solution of sodium dodecylphosphonate is described. This method offers several advantages, such as using of a cheap and environmentally benign reaction media, low loadings of sodium dodecylphosphonate as catalyst and...

Silica gel has been used for synthesis of biscoumarin derivatives starting from 4-hydroxycoumarin and aryl aldehydes. The reaction conditions are completely in agreement with green chemistry principles including sing water as media and a recyclable and safe catalyst. This method is also simple and inexpensive and leads to high yield of products in short reaction times.

In some people the inadequate amount of Beta-galactosidase enzyme, in layer of villous epithelium of the small intestine, causes the disorder of lactose intolerance. This examination was done to observe the existence of Beta-galactosidase enzyme that is produced by separated Lactobacillus from samples of dairy products (milk and cheese). Materials and Methods: Pasteurized and local...

We are interested in the problem of text layout as it relates to our work on the intelligent generation of integrated text and information graphics (e.g., tables, bar charts, plots, maps) the AutoBrief system (Kerpedjiev et al. 1997; Green, Carenini, & Moore 1998; Green et al. 1998). Intelligent layout generation is related to the problems of media allocation and cross-media cue generation. We ...
