The current situation of world’s environmental issues, indicates that not only the man-made environmental damages have not been diminished, but also has given rise to more acute issues such as water and soil pollution, biodiversity loss, ozone depletion, greenhouse phenomena, etc. One of the most prominent effects of urban development on environmental problems caused by solid waste generated in...

A linear, three-component (nitrate, phytoplankton, and zooplankton) biogeochemical model coupled to a one-dimensional turbulence closure fluid dynamic model successfully reproduces most of the thermal and biogeochemical features of three marine settings (Bermuda Station "S" in the oligotrophic portion of the North Atlantic subtropical gyre, Ocean Weather Station "India" in the North Atlantic su...

El Batts Pumping station is located in Fayoum Governorate on the right bank of existing Batts drain about 120 km south of Cairo, at entrance of 0.6 km north-west of Tamiya village. It is equipped with four vertical mixed flow pumping units. The main objectives of this pumping station are to increase the cultivated area by 10000 feddan in the north of Bahr Wahby, improve the irrigation for 20000...

The stable nitrogen isotopic composition of nitrate, concentrations of inorganic nitrogen and phosphorus, dissolved oxygen and nitrification rates were determined at six stations ranging from the oligotrophic North Pacific Subtropical Gyre (NPSG) to the more productive Eastern Tropical North Pacific (ETNP). Nitrification rates increased along the transect from a maximum rate of 1 nmol L 1 d 1 a...

The main objective of this research is to find the extent to which the minimal variability Ordered Weighted Averaging (OWA) model of seismic vulnerability assessment is sensitive to variation of optimism degree. There are a variety of models proposed for seismic vulnerability assessment. In order to examine the efficiency of seismic vulnerability assessment models, the stability of results coul...

Fine particles (PM2.5) have adverse impacts and risks on air quality human health. The present research focuses the concentrations of PM2.5, index (AQI), assessment hospital admissions due to COPD attributed PM2.5 particle levels in Tehran during last 10 years from 2011 2020. effects meteorological parameters (i.e., wind speed, humidity, temperature) AQI were examined using data 21 active monit...
