we studied cu concentration on part of aras riparian vegetation. cu was selected as an index metal due to polluting the aras river through agarak copper mines drainage. results of cu concentration in indicator plant have been examined using spss16. considering the situation of the copper mines as well as the habitat of the indicator plant, two stations before and after the exit of the industria...

The combination of habitat loss, climate change, direct persecution, introduced species and other components of the global environmental crisis has resulted in a rapid loss of biodiversity, including species, population and genetic diversity. Birds, which inhabit a wide spectrum of different habitat types, are particularly sensitive to and indicative of environmental changes. The Caucasus endem...

Background: Aras River is the main source of drinking water supply in northwestern provinces of Iran. The present study aimed to determine the concentration of heavy metals in the river on the border between Iran and Armenia. Methods: Three samples were taken from the Aras river water, the river bottom sediments and the root of Phragmites australis. In water sampling, the concentration of Hg, ...

  Various parasite species were found in Carassius carassius including Diplostomum spathaceum, Dactylogyrus sp.,Gyrodactylus sp. Ichthyophthirius multifiliis and Trichodinia sp . They were found in four rivers in West Azerbaijan Province (North-Western Iran) . A total of 207 live Carassius carassius from four rivers including Aras (72) Zariyneh (42) Nazlo (58) and Barandoz (35) were studied. Pa...

BACKGROUND Previous risk score is not simple for predicting existence of atherosclerotic renal artery stenosis (ARAS). Our study aims to develop a simple score to predict ARAS in eastern people with ischemic heart disease. METHODS There were two data sources involved in this study. From the data source of patients with acute myocardial infarction, we developed a clinical score for predicting ...

The ascending reticular activating system (ARAS) mediates arousal, an essential component of human consciousness. Lesions of the ARAS cause coma, the most severe disorder of consciousness. Because of current methodological limitations, including of postmortem tissue analysis, the neuroanatomic connectivity of the human ARAS is poorly understood. We applied the advanced imaging technique of high...

BACKGROUND Atherosclerotic renal artery stenosis (ARAS) is a progressive but potentially reversible chronic kidney disease. Although the high sensitivity and specificity of renal Doppler scanning (RDS) for ARAS has been reported in western countries, ARAS has not been detected by RDS. This study used magnetic resonance angiography (MRA) to evaluate the sensitivity and specificity of RDS for det...

Current management of atherosclerotic renal artery stenosis (ARAS) remains controversial. A major issue is the condition’s functional significance; specifically, what is the contribution of ARAS to a specified patient’s heart failure, hypertension, or progressive renal disease? Clinicians will often consider whether revascularization of ARAS is likely to alter a patient’s symptoms or prognosis....

Resource management is one of the main issues in Cloud Computing. In order to improve resource utilization of large Data Centers while delivering services with higher QoS to Cloud Clients, an automatic resource allocation strategy based on market Mechanism (ARAS-M) is proposed. Firstly, the architecture and the market model of ARAS-M are constructed, in which a QoS-refectitive utility function ...
