One of the main resonator factors in watershed soil erosion is inappropriateland management including conversion of pasture land to dry-land farming.Unfortunately, the changes of Gara Su watershed usages have been very common.Thus, in order to understand the influence of land use on runoff rate and soil loss, soillosses were investigated and determined under both pasture and dry-land agricultur...

Although hypersaline environments pose challenges to life because of the low water content (water activity), many such habitats appear to support eukaryotic microbes. This contribution presents brief reviews of our current knowledge on eukaryotes of water-column haloclines and brines from Deep Hypersaline Anoxic Basins (DHABs) of the Eastern Mediterranean, as well as shallow-water hypersaline m...

Hydrothermal fluids passing through sediments create a habitat hypothesized to influence the community structure of infaunal macrobenthos. Here we characterize the density, biomass, species composition, diversity, distributions, lifestyle, and nutritional sources of macroinfauna in hydrothermal sediments in NE and SW Pacific settings, and draw comparisons in search of faunal attributes characte...

In this paper, the results of the Spherical Oil Agglomeration of Abstract .45 micrometer superpits low grade co al pa rticles (Bagworth Colliery, U.K.) within a su spension are prese nte d.Demineralized agglomerates were recovered directly by sieving on a 106 micrometer sieve. Verygood reductions in the ash content of the feed coal samples were achieved. In order to reducethe high levels of the...

the main purpose of the study is determination of the pollutants hazard potential as well as environmental vulnerability of qarah su river. first the most significant pollutant sources in the qarah su river watershed were identified and then accordingly the pollution hazard potential rate was calculated in universal ranking system model setting. then, by generalizing the algebraic sum of the re...

در این کار حالت های همدوس مربوط به گروه های فشرده خاص مورد مطالعه قرار گرفته است. بطور کلی بررسی حالت های همدوس مربوط به سیستم های فیزیکی از مباحث مهمی است که در دهه های اخیر توجه فیزیکدان ها را به خود معطوف نموده است. این حالت ها، ویژه بردارهایی در فضای هیلبرت می باشند که در حالت کلی سه ویژگی اساسی پیوستگی، نرمالیزه پذیری و رابطه همانی را دارند. روش های مختلفی برای تعیین حالت های همدوس وجود دا...

The Cuatro Ciénegas Basin (CCB) is a rare oasis in the Chihuahuan Desert in the state of Coahuila, Mexico. It has a biological endemism similar to that of the Galapagos Islands, and its spring-fed ecosystems have very low nutrient content (nitrogen or phosphorous) and are dominated by diverse microbialites. Thus, it has proven to be a distinctive opportunity for the field of astrobiology, as th...

Advanced oxidation processes (AOPs) have led the way in the treatment of aqueous waste and are rapidly becoming the chosen technology for many applications. In this paper, COD reduction potential of leather tanning industry wastewaters by Electro-Fenton (EF) oxidation, as one of the AOPs, was experimentally evaluated. The wastewater sample was taken from an outlet of an equalization basin in a ...
