تحلیل خشکسالی و پارامترهای متاثر بر آن با استفاده از اطلاعات سنجش از دور پتانسیل بالایی برای بهبود دانش علمی در مورد خصوصیات خشکسالی و تاثیرات این پدیده بر روی پوشش گیاهی دارد. تحقیق پیش رو با هدف بررسی ارتباط میان شاخص های ماهواره ای و شاخص spi در مراتع شمالی استان گلستان صورت گرفت. بدین منظور ابتدا شاخص spi در میانگین های متحرک یک، سه و شش ماهه مورد محاسبه قرار گرفت، سپس نقشه های پهنه بندی با...
We applied a robust framework for agricultural drought identification in the State of Espírito Santo, Brazil, by employing Vegetation Condition Index (VCI) based on data obtained through Enhanced (EVI). By doing so, we analyzed interrelationships between VCI and anomalies Land Surface Temperature (LST), along with connections considering water deficits vulnerable areas. When it came to image pr...
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...
Summerer (Chemical Biology of the Genetic Code) at the university of Konstanz. It was funded by the " Graduiertenschule Chemical Biology " and the Aventis Foundation and the " Stiftung Stipendien-Fonds des Verbandes der Chemischen Industrie (VCI) " with a " Hoechst Doktorandenstipendium ". [1] Reproduced in part with the permission of M. Encoded Spin Labels for in vitro and in-cell EPR studies ...
Drought events were assessed using remote sensing index MODIS (MODerate resolution Imaging Spectroradiometer) and Standardized Precipitation Index (SPI) over the steppe regions of Algeria between 2000 2012. In this study, Vegetation Condition (VCI) Temperature (TCI) determined from Moderate Resolution Spectroradiometer (MODIS) sensor. The VCI (Vegetation Index) was based on Normalized Differenc...
This study utilised multi-temporal satellite data to characterize droughts across the five Agro-ecological zones (AEZ) of Zimbabwe at monthly, seasonal, sub-seasonal and annual scales (2000 2018) using a combination Satellite Pour l'Observation de la Terre (SPOT) Vegetation (VGT) Project for On-Board Autonomy-Vegetation (PROBA-V) derived Condition Index (VCI). The characterized were validated, ...

Drought is a major problematic phenomenon for the mostly semi-arid country of Iran. The north centralregions of Iran (north of Esfahan and Ghom province) have suffered from severe droughts several times duringthe last three decades. The frequent occurrence of drought in these regions is due to low and inconsistentprecipitation, abnormally high temperatures, increases in surface albedo and evapo...
Vascular dementia, being the most severe form of vascular cognitive impairment (VCI), is caused by cerebrovascular disease. Whether organophosphorus causes VCI remains unknown. Isocarbophos (0.5 mg/kg per 2 days) was intragastrically administrated to rats for 16 weeks. The structure and function of cerebral arteries were assayed. The learning and memory were evaluated by serial tests of step-do...
