Future drought-hazard assessments using standardized indices depend on the period used to calibrate probability distributions. This appears be particularly important in a changing climate with significant trends drought-related variables. study explores effect of different approaches project droughts, focus changes drought characteristics (frequency, duration, time spent drought, and spatial ex...

there are enormous quantities of unknown composition of hazardous wastes in tehran without any control, safe disposal and treatment. this study was done to identify hazardous wastes and to control this wastes by establishing a treatment, storage and disposal facility. according to available statistics there are 4461 different industries in tehran, out of which sample were chosen each having ove...

Water level monitoring is important for understanding the global hydrological cycle. Remotely-sensed indices that capture localized instantaneous responses have been extensively explored for water level reconstruction during the past two decades. However, the potential usage of the Palmer’s Drought Severity Index (PDSI) and El Niño Southern Oscillation (ENSO) indices for water level reconstruct...

Predictive power, for total and vascular mortality, of selected indices measured at baseline in the British National Diet and Nutrition Survey (community-living subset) of People Aged 65 Years and Over was tested. Mortality status and its primary and underlying causes were recorded for 1100 (mean age 76.7 (sd 7.5) years, 50.2% females) respondents from the baseline survey in 1994-5 until Septem...

The morphotectonic analysis is a useful time-saving and cost-effective method to assess tectonic activity, especially in large regions. In this paper, the study was carried out Kerman city which southeast of Iran part Central structural zone. Despite occurrence numerous historical instrumental earthquakes around city, there gap earthquake records that has obscured its seismicity status. aim ide...

natural hazards are among destructive agents that annually take thousands of lives and impose devastating damages in iran. spotting such a high risk areas can help reducing the amount of their probable risk. a 1:500000 liquefaction and landslide hazard zonation map developed for the southern shoreline of the caspian sea. this geotechnical hazard map divides the study area to 15 hazard classes (...

Background–The association of overweight/obesity with the incidence of cardiovascular diseases, especially stroke, has not been comprehensively examined in relatively lean populations in which stroke is more prevalent than coronary heart disease. Methods and Results–Pooled individual data from 16 Japanese cohorts comprising 45 235 participants ages 40 to 89 years without previous history of car...
