this study was intended to analyze the listening tapescripts of the elementary and pre-intermediate levels of total english textbooks from the pragmatic dimension of language functions and speech acts in order to see whether the listening tasks are pragmatically informative or not. for this purpose, 8 conversations from the two books were selected randomly, and then, the two pragmatic models of...
furan is a possible human carcinogen in many types of foods. a new and sensitive electroanalytical method for determination of furan has been developed and validated. the best condition forelectrochemical response was obtained with 0.1 m britton-rabinson buffer solution (ph=5) a glassy carbonelectrode (gce) was used as the working electrode, a ag/agcl/ kcl(sat.) electrode served as the referenc...
The lack of a high-yield, renewable and low-cost synthesis method limits the potential applications of boron nitride with impressive characterizations. In this study, a facile method is developed for the preparation of chemically functionalized boron nitride nanosheets (BNNSs) by considering the quantity and quality of chemical materials involved in the synthesis process. The proposed green met...
Debio 025 is a potent inhibitor of hepatitis C virus (HCV) replication (J. Paeshuyse et al., Hepatology 43:761-770, 2006). In phase I clinical studies, monotherapy (a Debio 025 dose of 1,200 mg twice a day) resulted in a mean maximal decrease in the viral load of 3.6 log(10) units (R. Flisiak et al., Hepatology 47:817-826, 2008), whereas a reduction of 4.6 log(10) units was obtained in phase II...

This study tested the effect of Sigma antioxidant supplement®, α-tocopherol (vitamin E) and L-ascorbic acid (vitamin C) in the culture medium of bovine embryos. In experiment 1, in vitro produced bovine zygotes were cultured in Human Tubal Fluid (HTF): Eagle’s Basic Medium (BME) with: Group 1 – 50 μm vitamin C; Group 2 – 200 μm vitamin E; Group 3 – 25 μm vitamin C and 100 μm vitamin E; Group 4 ...
The recovery of Clostridium difficile on a medium containing cefoxitin, cycloserine, fructose, and egg yolk was compared with that on media containing one of three preparations of sodium taurocholate. In aerobic environments contaminated with C. difficile, media containing either crude taurocholate from Mann Research Laboratories, New York, N.Y., or pure taurocholate from Sigma Chemical Co., St...
Materials: Dipentaerythitol penta-acrylate (5Acl), branched polyethyleneimine (BPEI, MW~ 25000), propylamine, hexylamine, octylamine, decylamine, sodium dodecyl sulfate (SDS) and Nile red (Technical grade, Sigma-N3013) were aquired from Sigma Aldrich, Bangalore, India. . n-butylamine was bought from Spectrochem Pvt. Ltd., Mumbai, India. HCl and Dimethyl sulfoxide (DMSO) were obtained from Fisch...
in this thesis, first the notion of weak mutual associativity (w.m.a.) and the necessary and sufficient condition for a $(l,gamma)$-associated hypersemigroup $(h, ast)$ derived from some family of $lesssim$-preordered semigroups to be a hypergroup, are given. second, by proving the fact that the concrete categories, semihypergroups and hypergroups have not free objects we will introduce t...
