Background: Enterotoxigenic Escherichia coli (ETEC) is one of the most important agents of travelers’ diarrheal diseases in the developing countries. The main purpose of this study was to determine the association of ETEC outbreaks with climatic and demographic variables in Yazd province of Iran. Methods: This study was done on 729 food-borne disease rectal swab samples, which gathered during ...

A multiscale model of the MJO is developed here that accounts, in a simplified fashion, for both the upscale transfer from synoptic to planetary scales of momentum and temperature from wave trains of thermally driven equatorial synoptic-scale circulations in a moving convective envelope as well as direct mean heating on planetary scales. This model involves idealized thermally driven congestus ...

BACKGROUND Ticks are the main vectors for transmission of different pathogens to human and animals. This survey was performed to find out distribution of ticks, which infested the domestic ruminants in Yazd Province, central Iran during year 2008-2009. METHODS A total number of 30 villages from both mountainous (20%) and plateau (80%) regions of the province were selected randomly. Ticks were...

â â â  aside from its annual and seasonal fluctuation, caspian sea level has sudden change with hourly and daily continuity caused by atmosphere circulation patterns. sometimes these fluctuations are so intense that they make irreparable damage to the economical and social activities in the coastal sea areas. the aim of this study is synoptic recognition of factors causing storm levels in the s...

abstract solar radiation, nowadays has a lot of application in different fields of agriculture, irrigation, and hydrology engineering and due to these various applications, different models has been proposed for it’s estimation. angstrom-prescott equation is one of the most important well known models for solar radiation estimation. this equation has empirically coefficient that various for eac...

Synoptic variability of low-cloud properties, temperature advection, and thermodynamic soundings of the trade wind boundary layer are analyzed, using the long data record from ocean weather station November (308N, 1408W). The variations in low-cloud amount at this subtropical site are most strongly correlated with variations in temperature advection, the stability of the lower troposphere, and ...
