cellulase production by the fungus trichoderma reesei was studied using sugar beet pulp (sbp) as a substrate. the subculture medium was a salt solution consisting of kh2po4, cacl2, etc. fungal cells were sub-cultured in an orbital shaker (180 rpm) at 30°c for 1-2 generations (two days for each generation) and were then used as an inoculum. exponential cells were inoculated into a medium contain...
the main purpose of this study was to investigate any relationship between high school efl teachers metaphorical understandings of their role in class and their self-efficacy beliefs. teachers metaphors were elicited through two different prompts: one picturing what they believed a language teacher should be like in class, and the other demonstrating what they are actually like in class; such...

objective: survey of molecular characterization of nucleoprotein gene of h9n2 avian influenza viruses and determination of the genetic relationship of iranian h9n2 viruses and other asian viruses. materials and methods: the nucleoprotein (np) genes from 4 isolates of h9n2 viruses isolated from commercial chickens in iran during 2008-2009 were amplified by rt-pcr method and sequenced. nucleotid...
implicit and unobserved errors and vulnerabilities issues usually arise in cryptographic protocols and especially in authentication protocols. this may enable an attacker to make serious damages to the desired system, such as having the access to or changing secret documents, interfering in bank transactions, having access to users’ accounts, or may be having the control all over the syste...
In this work, we used time-resolved imaging to study the dynamics of the laser-induced forward transfer (LIFT) process of a silver nanoparticle (NP) ink (NP size: 30–50 nm). LIFT is a versatile direct write technique in which a variety of functional materials can be transferred from a donor substrate to a receiving substrate with high spatial resolution. Two different LIFT configurations were e...
oxidative addition reactions of 1,4-diiodo-butane and 1,3-diiodo-propane with [ptme2(ph2phen)]; in which ph2phen=4,7-diphenyl-1,10-phenanthroline, were studied in different solvents such as acetone and benzene.oxidative addition reaction of [pt me2(ph2phen)] with i(ch2)4i and i(ch2)3i produced the [pt me2i(ch2)4(ph2phen)i] (1a) and [pt me2i(ch2)3(ph2phen)i] (1b).all the platinum (iv) products w...
the present study is paid to the evaluation of the welfare program of the unemployment insurance in iran. the main purpose which was the main reason for performing this thesis, was the unemployment insurance plan’s challenges in iran such as financial problems of this plan, prolongation of the credit receipt for some insured people, unemployment slow exiting from the unemployment insurance fund...
nonylphenol (np) is a well-known compound as having the potential to mimic the natural hormone 17β-estradiol (e2) and disrupt the endocrine system in a wide range of organisms. however, the ability of different isomers of this compound is different in exerting estrogenic effects. the objectives of this study were to estimate the effects of a straight side-chain np isomer (4-n-np) on the vitello...
objective(s)para-nonylphenol (p-np) is used in many industries and our previous study showed that p-np causes a reduction in rats bone marrow mesenchymal stem cells (mscs) viability. the aim of this study was to investigate the effect of p-np on osteogenic differentiation of mscs.materials and methodsmscs were isolated and expanded to 3rd passage, then cultured in dmem supplemented with osteoge...
