deposite the different criticisms on contrastive analysis it has been proved that the results of it(when processed)can be usuful in a tefl environment,specially at the level of phonology.this study is an attempt to compare and contrast the sound systems of kurdish and english for pedagogical aims. the consonants,vowels,stress and intonation of the twolanguages are described by the same model-ta...
background: we aimed to study the curative effects of botulinum a toxin (btx-a) on the treatment of post-herpetic neuralgia (pnh). methods: we enrolled 58 pnh patients and treated them with hypodermic injection of btx-a in xiangyang no.1 people’s hospital, hubei university of medicine, hubei, china. we measured and compared the visual analog score (vas), neuropathy pain scale (nps), quality of ...
Three radioligands have been commonly used to label putative nicotinic cholinoceptors in the mammalian central nervous system: the agonists [3H]nicotine and [3H]acetylcholine (C3H]ACh-in the presence of atropine to block muscarinic receptors), and the snake venom extract, [1251]-a-bungarotoxin([‘251]BTX), which acts as a nicotinic antagonist at the neuromuscular junction. Binding studies employ...
Introduction: Petrochemical industries are known as one of the most important sources of organic pollutants. In this study, the relationship between inhaled benzene, toluene, ethylbenzene and xylene (BTEX) concentration with some urine metabolites was investigated in a petrochemical complex Methods: This cross-sectional study was an analytical type with 60 inhalation air samples and biological...

abstract this paper discusses several commonly used models for strategic marketing¹ including market environmental analysis methods (i.e. swot and pest analysis) and strategic marketing tools and techniques (i.e. boston matrix and shell directional policy matrix)and shows how these models may help a firm to achieve its strategic goals. at first, the main reason for doing this research is de...
The tetralin hydrocracking process into benzene, toluene, and xylenes (BTX) was investigated over metal-modified (Ga, Nb, Ni, NiMo, Sn, W, Zr or H3[P(W3O10)4])/ZSM-5 zeolite catalysts without sulfidation procedures, mechanism analyzed, compared with a pristine microporous material in packed bed reactor under applied atmospheric pressure (p). This experimental study presents an investigation of ...
