In agricultural lands, high nutrient levels of nitrogen, phosphorus and potassium are very important due to the high need of plants. By improving the nutrient content of sodium soils, the fertility and growth of the plants improve. Accordingly, in order to investigate the effect of underground drainage on soil quality in Khuzestan region, this experiment was carried out in a completely randomiz...

Knowledge of transport and degradation of polycyclic aromatic hydrocarbons (PAHs) is important in assessing PAH contamination of soils and water resources. The transport of naphthalene, anthracene, pyrene and phenanthrene was determined in a contaminated calcareous soil obtained from the Shadegan wetland (Khozestan, Iran) considering a column study in laboratory conditions. The PAHs were added ...

Introduction Bioaccumulation of heavy metals in tissues of animals has received considerable attention because of the lethal and sublethal effects of their accumulation. Heavy metals come from industrial sources, storm water runoff, and agricultural runoff, as well as from natural erosion, biogeochemical cycles, and volcanism. They enter the food chain via air, water, soil and biota, accumulati...

Geological facies interpretation is essential for reservoir studying. The method of classification and identification seismic traces is a powerful approach for geological facies classification and distinction. Use of neural networks as classifiers is increasing in different sciences like seismic. They are computer efficient and ideal for patterns identification. They can simply learn new algori...

Bovine herpesvirus type-1 (BoHV-1) is a DNA virus that is classified in the family Herpesviridae, subfamily Alphaherpesvirinae and genus Varicellovirus. This virus causes the respiratory disease, abortion, conjunctivitis, infectious pustular vulvovaginitis or balanoposthitis and other clinical forms of the complex diseases. The aim of this study was to evaluate the seroprevalence and ri...
