در این تحقیق نحوه فعالیت سوسک های شکارگر خانواده coccinellidae برروی پسیل معمولی پسته agonoscena pistaciae burckhardt & lauerer ( مهمترین آفت موجود در باغات پسته ایران) در طبیعت و آزمایشگاه مورد بررسی قرار گرفت.در این تحقیق سعی گردیده اهداف زیر دنبال شود: بررسی تنوع کفشدوزک پسیل خوار در باغ های پسته رفسنجان ، مطالعه میزان پسیل خواری کفشدوزک ها ( مراحل لاروی و حشره کامل) در شرایط آزمایش...
Radiation detection is essential for determining of radiation dose. Depend on the detector and dosimetry method, detection process is performed in different levels. Pulse counting is the first level of detection. Typically, the output of a radiation detector for determining value of the radiation dose cannot be used directly. Through changing the response function or the readout detector, is tr...
The latest advances in the development of a fluorescent nuclear track detector (FNTD) for neutron and heavy charged particle dosimetry are described and compared with CR-39 plastic nuclear etched track detectors (PNTDs). The technique combines a new luminescent aluminium oxide single crystal detector (Al(2)O(3):C,Mg) with an imaging technique based on laser scanning and confocal fluorescence de...
Vegetation moderates a microclimate by casting shadows, increasing light reflection, evaporation and perspiration; and correcting wind patterns. The present study aims to investigate the microclimatic role of vegetated surfaces and bodies in improving thermal comfort in outdoor spaces between buildings. The main research question is which of the green system modes, that is, horizontal vegetatio...
Introduction: Radiotherapy (RT) plan evaluation using dose response models has become a feasible approach in routine clinical practice. Although there are several tools for this task, they suffer from limitations including number of different dose response models and parameters. In the present study, we aimed to develop a free program for RT plan evaluation based on a variety ...
Background: The trabecular bone changes in the tibia of C3H/HeN mice were measured 12 weeks after whole body irradiation with various doses of fast neutrons (0-2.4 Gy) or 137Cs-generated gamma-rays (0-6 Gy). Materials and Methods: Serum calcium, phosphorus, estradiol concentration and alkaline phosphatase activity were measured. Tibiae were anal...
Background & Aims: Multiple evidences available about zinc oxide nanoparticles (nano-ZnO) ameliorative effects on neuroinflammation that worked in contrast to mechanisms activate with paclitaxel. In this study, effect of local and intraperitoneal application of nano-ZnO on paclitaxel-induced acute and chronic thermal hyperalgesia in mice was evaluated. Materials & Methods: Adult male mic...
ntroduction: The purpose of this study was to measure the radioactivity in the agricultural soil of south-east of Shazand Refinery Complex to determine both reliable baseline data on the radiation level and the radiation dose exposure to the farmers and inhabitants of the studied area. Material and Methods: This study was conducted on 21 soil...
