in this thesis a calibration transfer method is used to achieve bilinearity for augmented first order kinetic data. first, the proposed method is investigated using simulated data and next the concept is applied to experimental data. the experimental data consists of spectroscopic monitoring of the first order degradation reaction of carbaryl. this component is used for control of pests in frui...
writing an academic article requires the researchers to provide support for their works by learning how to cite the works of others. various studies regarding the analysis of citation in m.a theses have been done, while little work has been done on comparison of citations among elt scopus journal articles, and so the dearth of research in this area demands for further investigation into citatio...
چاودار از گیاهان مهم خانواده poaceae به شمار می رود که بومی ایران می باشد. در این تحقیق ابتدا تنوع ژنتیکی 70 جمعیت از جنس چاودار (secale l.) که از نقاط مختلف ایران جمع آوری شده بود بر اساس 17 صفت کمی و 14 صفت کیفی ریخت شناسی مورد بررسی قرار گرفت. گونه ها و زیرگونه های این جنس با استفاده از روش تجزیه به مولفه های اصلی (principal component analysis, pca) و تجزیه تابع تشخیص(discriminant function a...

background celiac disease (cd) is a disorder associated with body reaction to gluten. after the gluten intake, an immune reaction against the protein occurs and damages villi of small intestine in celiac patients gradually. objectives the osc, a filtering method for minimization of inter- and intra-spectrometer variations that influence on data acquisition, was applied to biofluid nmr data of c...
When planning workings of slate extraction by mechanical means, it is important to know the quality of the rock mass to optimize the results of the cuttings in the extraction bank, because techniques to be used depend on relative percent of first quality or second quality slate. In this paper, a methodology for quality evaluation applied to slate extraction is developed in three phases, as a to...
introduction: a modern technique for elemental analysis of biological samples is laser induced breakdown spectroscopy (libs). this technique is based on emission of excited atoms, ions, and molecules in plasma produced by focusing a high power laser pulses on sample surface. because of several advantages of libs including little or no sample preparation; minimally invasive; fast analysis time a...
objective: sexual addiction is a psychiatric disorder with unpleasant personal, inter-personal, legal, social, and physical outcomes for the patients. the cycle of this disorder is based on a false belief system known as early maladaptive schemas. this study aimed to examine and compare maladaptive cognitive schemas in sex addicts and normal people. methods: in the present study, a causal-compa...
