INTRODUCTION Although water pipe tobacco smoking is common in Lebanon and Syria, prevalence in neighboring Jordan is uncertain. The purposes of this study were (a) to assess the prevalence of water pipe tobacco smoking among university students in Jordan and (b) to determine associations between sociodemographic variables and water pipe tobacco smoking in this population. METHODS A trained in...

Many applications of water resources planning and management depend on continuous streamflow predictions. A lack data sources makes it difficult to predict stream flows in many world regions, including Saudi Arabia. Therefore, using simple, parsimonious models is more attractive areas where scarce since they contain few parameters require minimal input data. This study investigates the ability ...

A GCM cloud microphysics parameterization is tested and improved using the CCCMA single-column model with cloud properties obtained at the Surface Heat Budget of the Arctic Ocean experiment (SHEBA) during the period of November 1997 to September 1998. The ECMWF reanalysis water vapor profile is scaled with rawinsonde data so that the new relative humidity profiles are compatible with rawinsonde...

The calculation of the total amount pollutants entering river is key to control system. Since non-point source pollution has not been monitored normally and effectively, based on principle balance input output pollutants, 2009-2013 Qinghe water quality monitoring data, survey data were used establish a binary statistics model. MATLAB software solve results show that model strong assimilation ab...

the purpose of this study is to investigate the effect of physical activity onmemory and dynamic balance of elder people. subjects (n=15) were selected asvolunteers. the intervention was performed in an eighteen session period, threetimes a week (each session, 45 minutes). yoga training was performed for mentalrelaxation. wexler test was performed for memory evaluation. seat up test wasused to ...

This paper attempts to search for a suitable structure of a monthly water yield model applicable for seasonally snowcovered mountainous catchments located in a semiarid area. In this respect several model structures based on a soil water balance concept were compared. The main distinction between the different structures was made by the inclusion of either a linear or a nonlinear transformation...

Relationships between satellite-derived water quality variables and river discharges, concentrations and loads of nutrients, organic carbon, and sediments were investigated over a 9-year period (2003–2011) in Pensacola Bay, Florida, USA. These analyses were conducted to better understand which river forcing factors were the primary drivers of estuarine variability in several water quality varia...
