In this article, the Environmental pollution in Iraq was studied by using the remote sensing techniques for the period (2010-2014). In general, the environmental pollution can be divided into three major parts: Air, Water, and soil pollutions. To overcome the problem, multi-satellite images with different resolution and bands at different dates were used to detect and quantize the source of pol...
background alkylphenol polyethoxylates (apneos) and their metabolites disposal from sewage treatment plants (stp) are of particular concern due to their persistence, toxicity to aquatic organisms, and a potential endocrine disruptor. in this work, we focused on the determination of nonylphenol (np) and nonylphenol polyethoxylate (npneos) in water were collected from karun river. material and me...
abstract in aggregate, active forms of reactive silica with mineral names are sometimes associated with sand and gravel in concrete mixture. alkali hydroxides originated from alkalis in the cement or other resources form an alkaline silica gel with this reactive silica which becomes swallowed and expanded during time causing damage to concrete. there have been growing researches on alkaline r...
there is no doubt that human being needs to become integrated with industry and industry needs to be progressed, daily. on the other hand, serious events in industrial units specially in oil industries has been shown that such damages and events are industry related ones. the consequence of such events and damages which resulted in chemical and poisoned explosions and loss of life and property ...
flow in natural river bends is a complex and turbulent phenomenon which affects the scour and sedimentations and causes an irregular bed topography on the bed. for the reason, the flow hydralics and the parameters which affect the flow to be studied and understand. in this study the effect of bed and wall roughness using the software fluent discussed in a sharp 90-degree flume bend with 40.3cm ...
Providing faultless proceeding of the engineer in order to protect the rivers, requires understanding the morphological behavior of the river and studying the hydrodynamic phenomena of the area. The intersection of the Karun rivers as the largest and longest river in Iran with the Arvand border river is of considerable importance due to its strategic location. In this paper, using field measure...
khuzestan province is considered as one of iran's agricultural hubs, food production andsupply make it necessary to use water and soil resources to the optimum potential.agricultural drainage waters, with their high volume and decentralized nature, are the mainsource of return flow to the karun river. these sources include pesticides and nutrients(nitrate, phosphate) and have high pollutio...
in new management approaches, in the organizations with inflexible structure, existing of red tapes and interruptions caused by limitations and also non-compliance with environmental changes, create demotivation among staff. with regard to the influence of job motivational potential and its relationship to the type of organizational structure( enabling and dissuasive), the goal of this research...
Salt pollution and human-accelerated weathering are shifting the chemical composition of major ions in fresh water and increasing salinization and alkalinization across North America. We propose a concept, the freshwater salinization syndrome, which links salinization and alkalinization processes. This syndrome manifests as concurrent trends in specific conductance, pH, alkalinity, and base cat...
