Despite the importance of Amu Darya and Kabul River Basins as a region in which more than 15 million people live, its vulnerability to global warming, only few studies addressed issue linkage meteorological parameters on vegetation for eastern basins Afghanistan. In this study, data from MODIS, Global Precipitation Measurement Mission (GPM), Land Data Assimilation System (GLDAS) was used period...

Diagnosis of vascular cognitive impairment (VCI) or vascular dementia (VaD) is highly dependent on operational definitions. Among 480 cases of incident dementia in the Cardiovascular Health Study (CHS) Cognition Study, Lopez et al1 demonstrated how findings from brain imaging and choice of diagnostic criteria influence the classification of VaD. As shown by previous investigators, the number of...

Insulin stimulates nerve arterial vasodilation through a nitric oxide (NO) synthase (NOS) mechanism. Experimental diabetes reduces vasa nervorum NO reactivity. Studies investigating hyperglycemia and nerve arterial vasodilation typically omit insulin treatment and use sedentary rats resulting in severe hyperglycemia. We tested the hypotheses that 1) insulin-treated experimental diabetes and ina...

This paper addresses the process of dynamic data ow analysis using virtual code integration (VCI), often refered to as dynamic binary rewriting. This article will try to demonstrate all of the techniques that were applied in the SpiderPig project [15]. It will also discuss the main di erences between the methods that were employed and those used in other available software, as well as introduci...

BACKGROUND The assessment of quality of life is critical in ascertaining the benefit of interventions aimed to reduce morbidity among individuals with cognitive impairment. However, the assessment of quality of life is challenging in this population due to the uncertain validity of patient responses as cognitive function declines. Hence, we examined the level of agreement between patient and pr...

Vascular Dementia (VaD) and Vascular Cognitive Impairment (VCI) are increasingly common worldwide. Nevertheless, the clinical-neuropsychiatric profile of these patients at presentation is still poorly characterized in developing countries. OBJECTIVE We aimed to characterize the prevalence of neuropsychiatric symptoms, as well as the clinical and cognitive profile of patients with VaD and VCI ...

Drought is a natural disaster. Because a significant impact on the agricultural and economy sector, it affects the lives of local residents. With Using of the remote sensing, drought can be studied through its effects on plants and agriculture resulting in more accurate and effective results found for modeling drought. In this study, the efficiency of agricultural drought indicators for estimat...

خشکسالی یکی از بلایای طبیعی است که به دلیل تاثیر قابل ملاحظه ای که بر روی بخش کشاورزی و اقتصاد دارد، زندگی انسان ها را تحت تاثیر قرار می دهد. با استفاده از دانش سنجش از دور می توان خشکسالی را از طریق اثراتی که بر روی گیاهان دارد، مطالعه و به نتایج دقیق تر و موثر­­تری برای مدل سازی خشکسالی دست یافت. در این پژوهش کارایی شاخص وضعیت پوشش گیاهی در تحلیل خشکسالی کشاورزی از طریق سنجش از دور مورد ارزیا...

پوشش گیاهی در هر منطقه نقشی کلیدی در مدل سازی تغییرات و یا حفظ اکوسیستم دارد. شاخصه های خشکسالی هواشناسی که مستقیماً از روی داده های هواشناسی نظیر بارندگی محاسبه می شوند، در صورت فقدان داده های مذکور، در پایش خشکسالی مفید واقع نخواهند شد، لذا تکنیک سنجش از دور می تواند ابزاری مفید در پایش خشکسالی به شمار رود. در این تحقیق با استفاده از تصاویر ماهواره ای سنجنده مودیس روند تغییرات شاخص نرمال شده پ...
