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...
a novel acrylic acid-functionalized fe3o4 magnetic nanoparticle with a core-shell structure was developed for utilization as a heterogeneous organosuperacid in chemical transformations. the structural, surface, and magnetic characteristics of the nanosized catalyst were investigated by various techniques such as transmission electron microscopy (tem), thermogravimetric analysis (tga), and ft-ir...
از جمله معروفترین آنتی بیوتیکهای ضدسرطان، می توان به آدریامایسین دانومایسین و اکتینومایسین d اشاره کرد. این داروها در معالجه سرطان از طریق شیمی درمانی مودر استفاده قرار می گیرند. هدف اصلی این داروها در سلول، مولکول dna است . از آنجا که مولکول dna در داخل هسته سلول به صورت برهنه و آزاد نیست بلکه در اتصال با ترکیبات دیگری مثل پروتئین های هسیتونی و غیرهیستونی می باشد، میان کنش این داروها با پروتئی...
sange siyah dam is located two kilometers down the kabod khani village. the environ of ghorrve city in kurdestan province. this is an clay core dam. in this dam instrumentation is performed in three section and consist of electrical piezometers, total pressure cells, settlement cells and so on. the main objective of instrumentation is to control the behavior of dam body and foundation, end else...
objective: citation analysis is a bibliometric method used for the calculation of the mean number of citations and detection of highly cited references, frequency distribution of citations in different languages, update rate, efficacy of resources and number of core journals of a scientific domain. this process elucidates the information needs of researchers in a specific realm of science and e...
the objective of the present study was to identify managerial competencies. this study reviewed existing managerial competencies in a cultural context resulting in the development of a broad based psychometrically sound leadership questionnaire. the unit of analysis of the research was a theoretical and experimental research related to managerial competencies, provided from seventeen iranian an...
in the present study, the effect of core on shear lag phenomenon in tubular structures is investigated. three different tubular structure models including model without core, model with central core and model with central core but eliminated in last 15 stories have been analyzed. a shear lag index is defined for evaluating these models. from examination of the results, the effective influence o...
statement of problem: currently there are three recognized theories about the diameter of prepared dowel space in endodontically treated teeth. diameter of the dowel is commonly contributed to the root fracture. purpose: this study used a 3 dimensional (3d) finite element method to predict stress distribution in endodontically treated central maxillary tooth with cast post and core with various...
وکتورهای آدنو ویروس همواره در طراحی واکسن برای کنترل ویروس hcv مورد استفاده قرار گرفته اند. با آنکه ژن core ویروس به دلیل شباهت بالا در بین ژنوتیپها در واکسنهای مختلف مورد استفاده قرار گرفته و از لحاظ تئوری از بهترین کاندیدهای واکسن به شمار می آید، دسته ای ازجدیدترین مطالعات به دلیل نقائص وارد بر ژن کامل از قسمتهای کوتاه شده ژن در ساخت واکسن استفاده می کنند. تاکنون مطالعه ای که به ارزیابی سیستم...
construction of asphaltic core dams is a relatively novel method especially in iran. iran is located in a region with high seismicity risk. therefore, many researchers have focused on the behavior of such types of dams under earthquake loading. in this research, the behavior of asphaltic core rockfill dams (acrd) has been studied under earthquake loading using nonlinear dynamic analysis method ...
