چکیده هدف اصلی این پژوهش تعیین رابطه استراتژیهای خود رهبری و خلاقیت اعضای هیات علمی دانشگاه علم و صنعت بوده است. در این پژوهش از روش توصیفی از نوع همبستگی استفاده شده است. جامعه آماری پژوهش کلیه اعضای هیات علمی دانشگاه علم و صنعت در سال تحصیلی 88-1387 بود که بالغ بر345 نفربودندو از این تعداد، 119 نفر استاد با استفاده از روش نمونه گیری تصادفی طبقه ای متناسب با حجم انتخاب شد. ابزار جمع آوری داده...
Background: Clarithromycin resistance in Helicbacter pylori has been found to be associated with point mutations in 23s rRNA gene leads to reduced affinity of the antibiotic to its ribosomal target or changing the site of methylation. The aim of this study was to determine the most important point mutations in 23s rRNA gene in H. pylori that are closely related to clarith-romycin resistance amo...
in chapter one we will describe definitions and preliminary results to provide the global context of our own results to be presented in detail in the subsequent chapters in chapter two we consider degree-one maps of the circle and we study their rotation set. our main result in this chapter says that if the map is topologically mixing then its rotation interval is nontrivial (that is, not reduc...
the present research has been deducted from a provincial research project which aims at determining the relationship of variables of variables of occupational self-concept, intelligence beliefs and metacognitive with entrepreneurship among the students of payame noor university of kurdistan. the volume of the samples was 1080 students (576 female and 504 male students). the research methodology...
Gene amplification is believed to play an important role in antibiotic resistance but has been rarely documented in clinical settings because of its unstable nature. We report a rise in MICs from 0.5 to 16 μg/ml in successive Acinetobacter baumannii isolated over 4 days from a patient being treated with tobramycin for an infection by multidrug-resistant A. baumannii, resulting in therapeutic fa...
dna methylation as an epigenetic mediator plays the important role in spatial and temporal gene regulation and ensures the stability and the plasticity of organism. in this investigation, methylation sensitive amplification polymorphism (msap) were assessed in ccgg sites on a halophytic plant, aeluropuslittoralis in response to different temperature stresses including freezing, low and high tem...
the concepts of similarity and dissimilarity have been the interest of many researchers. basically, in the studies the similarity between two objects or phenomena, has been discussed. in this thesis, we consider the case when the resemblance or similarity among three objects or phenomena of a set, 3-similarity in our terminology, is desired. later we will extend our definitions and propos...
the purpose of this study was to investigate the relationship between family functioning and marital adjustment humor couples are due to the nature and objectives of the research and application of methods for its implementation correlation was used. the study population consisted of all the couples in the city who uses random cluster sampling of 200 students were selected as sample. data from ...
among the low–dimensional allotropes of carbon, nanotubes and graphene have attracted very much attention from nano–science and nanotechnology specialists. they have been proposed as building blocks in nanometer device engineering. however, these structures are not defect–free. in this thesis, we focused on defective carbon nanotubes and graphene, and studied the effect of couple of very common...
In this study, SRAP molecular maker approach was performed to investigate genetic diversity in the Salvia genus. A total of 205 DNA bands were produced from PCR amplification of 11 Salvia species and populations using 25 selective primer combinations, of which 204 polymorphic genetic loci accounted. The total number of amplified fragments ranged from 3 to 15. The genetic similarities of 11 coll...
