Determining the relative contributions of human activities and climate change to variations of runoff in basin is very important for sustainable management of water resources. In this study, seven methods were used to determine these relative contributions in the Ghaleh-Shahrokh watershed as the main upper catchment of Zayandeh-Roud River. These seven methods can be divided into two main catego...
phytoplankton taxa composition of the caspian sea were evaluated by using samples collected at 12 stations along the iranian coast of the caspian sea between 1996 and 2010. this study identified 158 phytoplankton species consisted of diatoms (70 species), dinoflagellates (23 species), chlorophytes (29 species), cyanophytes (31 species), and euglenoids (5 species). the dominant species were the ...
In fish, the role that cholinesterases (ChEs) play in tissues other than those implicated in neural activity, as well as the involvement of carboxylesterases (CbEs) and cytochrome P450 isoenzymes (CYPs) in drug metabolism needs investigation. For that, Senegalese sole (Solea senegalensis) specimens were selected for characterization of several type B esterases and hepatic CYPs in order to furth...
مقدمه: سندرم متابولیک یک فنوتیپ مرکب است که 32 درصد از افراد ایرانی به آن مبتلا می باشند. این بیماری با افزایش ریسک ابتلا به بیماری های قلبی- عروقی همراه می باشد. فراوانترین فنوتیپ این بیماری کاهش میزان hdl-c می باشد. برای شناسایی دلیل کاهشhdl-c نیاز به شناسایی ژنهای اثر گذار بر متابولیسم آن می باشد . مواد و روش ها: در مطالعه حاضر 107 خانواده با الگوی سندرم متابولیک و کاهش میزان hdl-c جهت بررس...
today, the route for economic development in most countries is the same as international open competitive economy. economic institutes well known that supportive public economy belonged on the past and they may compete in the global economy. it is obvious that if they have no competitive potency or not familiar with competition technique, they may be devastated. banking system aims to collect t...
The vegetation covering of a region has a direct correlation with climate. So if data is available for vegetation cover, the second variable (climate) can be easily predicted and in reverse. The dominant species in a region are indication of its climatic conditions and vice versa. Accordingly, this is of significance in the science of historical botany. Fortunately, from the first millennium A...
Nutrient enrichment in water and sediments due to excessive anthropogenic activities in recent years has caused excessive algal growth in the Caspian Sea. The current study was conducted to determine the abundance of phytoplankton community, the dominant species and chlorophyll-a [Chl-a] concentration during algal blooms in the Iranian coastal waters of Caspian Sea through four seasons from 201...
Phytoplankton study has become more significant in the Caspian Sea due to the occurrence of ecological events such as algal blooms and the introduction of the invader species(Ctenophore, Mnemiopsis leidyi). A seasonal study was conducted to investigate the features of phytoplankton community one decade after this invasion in the Iranian coast of Caspian Sea during 2009-2010. According to the re...
Correlational studies supporting the link between learners’ multiple intelligences and their learning are superseded by interventionist attempts to explore direct applications of Multiple Intelligence (MI) Theory in language teaching and learning. This quasi-experimental study examined the extent to which engaging ELT major university students in writing tasks, compatible to their dominant inte...
