Climate change and drought have negative consequences, including the spread of deserts. In this research, the impact of climate change on some climatic variables (temperature and precipitation) of Firoozkooh and Garmsar synoptic stations in the period 2030-2011 and 2065-2046 using LARS-WG model under scenario A2, B2 and A1B and finally desertification hazard and risk using ESAs model in Hablehr...
The interest in cellulose and its derivatives has been exponentially increasing due to its excellent thermal stability, biocompatibility, chemical persistence and biodegradability. Among various cellulose derivatives, cellulose acetate (CA) has been applied in many applications including sensor systems, drug delivery systems, separation membrane, and tissue engineering. Recently, the electrospu...
PURPOSE Hypoxia is associated with adverse outcome for a number of solid tumors, including cervical carcinomas. Direct pO(2) measurement requires specialized equipment and expertise that is not generally available. Immunohistochemical measurement of intrinsic tissue markers of hypoxia is an alternative approach. Recent studies suggest that carbonic anhydrase IX (CA IX), which is regulated via h...
Land use change prediction is an important factor in appropriate planning and integrated ecological management of watersheds. There are various methods for modeling and prediction of land use, i.e. Markov chain and CA Markov. In this research, for predicting the land use of Gareen watershed in Iran in 2042, Landsat satellite images of 1986, 2000 and 2014, and the Markov chain and CA Markov was ...
Tractable classes constitute an important issue in Artificial Intelligence to define new islands of tractability for reasoning or problem solving. In the area of constraint networks, numerous tractable classes have been defined, and recently, the Broken Triangle Property (BTP (Cooper, Jeavons, and Salamon 2010)) has been shown as one of the most important of them, this class including several c...
Fast-mixing and rapid-filtration techniques were used to analyze the kinetics of potassium-depolarization-dependent (delta K+ = 47.5 mM) influx of 45Ca into synaptosomes, in the time range from 50 msec to 5 sec. The results are consistent with the presence in synaptosomes of a homogeneous population of voltage-sensitive Ca channels. With 1 mM Cao in the medium, the delta K+-dependent Ca influx ...
Desertification process has always been led to destruction of vegetation cover and soil and water resources that can occur in different climatic conditions, the intensity of which depends on the natural conditions of the region. Due to the increase in destruction of vegetation as one of the most important consequences of desertification, monitoring the changes and assessment of their trends are...
Prioritization of watershed basins includes classification of sub-basins on the basis of the existing conditions and erosion intensity, which ultimately leads to protective operations and watershed management in more significant and susceptible sub-basins. In this research, in order to prioritize Ghezel Owzan-Sefidrud sub-basins against sensitivity to erosion, linear and form-based morphometric...
In all animals, collective cell movement is an essential process in many events, including wound healing and embryonic development. However, our understanding of what characterizes the emergence of multicellular collective behavior is still far from complete. In this article we showed the fundamental cellular processes that drive collective cell movement by means of integrated approaches, inclu...
