introduction: drought is a creeping natural phenomenon, which can occur in any region. such phenomenon not only affects the region subjected to drought, but its adverse effects can also be extended to other adjacent regions. this phenomenon mainly starts with water deficiency (say less than long- term mean of variable under study such as rainfall, streamflow, groundwater level or soil moisture)...

drought is still limited in most crops is produced. morphological and physiological knowledge to improve drought resistance under drought conditions created problems important is the fact each of these genetic relationships and processes associated with the exact amount of important plant and grain yield is unknown. the other hand, heritability of grain yield under water is reduced. improve the...

Significant increases in tree mortality due to drought-induced physiological stress have been documented worldwide. This trend is likely to continue with increased frequency and severity of extreme drought events in the future. Therefore, understanding the factors that influence variability in drought responses among trees will be critical to predicting ecosystem responses to climate change and...

Drought is a major environmental disaster in many parts of the world. Knowledge about the timing, severity and extentof drought can aid planning and decision-making. Drought indices derived from in-situ meteorological data have coarsespatial and temporal resolutions, thus, obtaining a real-time drought condition over a large area is difficult. This studyused advanced very high resolution radiom...

Abstract. Drought is a sustained period of below-normal water availability. It recurring and worldwide phenomenon, but the Mediterranean Basin seen as very vulnerable environment in this perspective, understanding historical drought conditions area necessary to plan mitigation strategies further face future climate change impacts. The current research was aimed at description evolution for Camp...

introduction: traditional iranian medicine (tim) is accompanied by little side effects in experience. the mechanisms involved in tim are not much clear. the purpose of this study is assessment of differences of warm and cold nature persons in neuroendocrine system and cytokine pattern (th1/th2) of immune responses. methods: thirty seven 20 to 40 years old male volunteers were divided into 2 gro...
