zonings of seismicity of fars province in iran and comparison itsâ finding to other researches results is aim of this paper. we used statistical method for analyzing recorded earthquakes in study area during 110 years (1900 â 2010), using gis methods for this zoning. by using usgs seismic data of the region and fault maps, excel software and arcgis, we prepare a seismic risk map of study ar...
Abstract In calcareous and saline soils, the adverse effect of some ions such as bicarbonate, boron, magnesium, and especially sodium, and the imbalance of nutrients’ concentrations are essential factors which reduce plant growth. A greenhouse experiment was conducted to study the effect of sodium (Na) and magnesium (Mg) on some growth traits and chlorophyll content of pistachio seedlings (cv....
Activation of extracellular signal-regulated kinase (ERK) has been shown to be necessary for NMDA receptor-dependent long-term potentiation (LTP). We studied the role of ERK in three forms of NMDA receptor-independent LTP: LTP induced by very high-frequency stimulation (200 Hz-LTP), LTP induced by the K(+) channel blocker tetraethylammonium (TEA) (TEA-LTP), and mossy fiber (MF) LTP (MF-LTP). We...
Fluoxetine is a 5-hydroxytryptamine (5-HT, serotonin)-selective reuptake inhibitor (SSRI) and is one of the main drugs used for the treatment of depression. Because it takes 2 to 3 weeks of treatment before clinical efficacy is manifest, the acute actions of fluoxetine cannot account for the clinical actions of the drug. The chronic effects of fluoxetine have not been completely delineated. The...
در این پایان نامه طراحی جدیدی برای کنترلر فازی mixed-signal با قابلیت برنامه پذیری بالا در پروسه cmos وتکنولوژی 0.35µm جهت کاربرد های general purpose با توان مصرفی و area پایین و سرعت و دقت بالا ارائه شده است. ورودی این ساختار ولتاژ با قابلیت تغییر رنج ورودی بوده بنابراین به شکل مطلوبی قابلیت ارتباط با سنسورها و ادوات اندازه گیری را در ورودی کنترلر خواهد داشت. برای پیاده سازی این ایده، ساختار...
Fire, as a natural ecological disturbance factor in forest, this study located in the Marivan region, Northern Zagros forest, and western Iranian state of Kurdistan. In each burned and unburned area 30 circle sample plot (1000 m2) were collected by randomized–systematic method in the 100×200 m net (in total 60 plots). In every sample plot the kind of species, number of tree, the heig...
land use change may influence many natural phenomena and ecological processes, including runoff, soil erosion, sedimentation and soil conditions. decreasing of forest area in the north of iran is one of the critical problems in recent years. the aims of this study are to detect land use changes between 1967 to 2002 using satellite images of land sat 7 etm+ (2002), aerial photos and digital topo...
Soil or relative percentage of sand, silt and clay reflects some texture characteristics such as permeability, water holding capacity, CEC, and soil behavior in return to the plow and other tillage operations is very important. The study area covers an area of 1715.4 hectares, near the Aiej soil dam, East of Jooneghan city, Chaharmahal and Bakhtiari Province. For this study, 40 disturbed soil s...
This paper presents pluralism as a historical process. The term pluralism frequently appears not only in the field of political philosophy but also in social sciences. In one sense, the growing literature is stimulating and enriching, nevertheless the abundance of material attempting to explain the various interpretations of pluralist theory can be convoluted and overwhelming. Despite the const...
