Modifying human activities is key to achieving land degradation neutrality in rangelands. Rangeland stakeholders encompass different ownership regimes; however, little known about whether models benefit or degrade social conditions and ecosystem services the Middle East. The aim of this research was determine effects Collective Council on ecological indicators wintery rangeland Iran. study incl...

the hydrolysis of cadmium nitrate was studied spectrophotometrically at different ionic strengthsof sodium perchlorate in a wide ph range, 1-12, and at 25 c. least squares calculations areconsistent with the formation of m(oh)+, m(oh)2, m(oh)3- and m(oh)42- species, which m iscd2+. the dependency on ionic strength in the background electrolyte solutions was taken intoaccount by using a debye-hu...

the main purpose of this research paper is to compare qiujiahe formation (є1q) and longmaxi formation (s1ln) in north sichuan basin where shale gas exploration has not been fully researched, and hence represents the possibility of shale gas concentration under the complex geological conditions. based on valid laboratorial analysis, there are optimistic prospects for є1q and s1ln of research are...

shahnameh researchers have not made enough attempts to find the correct forms of its toponymy. the variants of these names are frequently incompatible and sometimes incorrect. obviously the copiers of manuscripts have made little effort to record such names correctly and even at times they have inadvertently replaced the original names with the ones sounding more familiar to them. based on the ...

understanding the performance and role of each formation in a petroleum play is crucial for the efficient and precise exploration and exploitation of trapped hydrocarbons in a sedimentary basin. the lorestan basin is one of the most important hydrocarbon basins of iran, and it includes various oil-prone potential source rocks and reservoir rocks. previous geochemical studies of the basin were n...

Bats are unusual among mammals in showing great ecological diversity even among closely related species and are thus well suited for studies of adaptation to the ecological background. Here we investigate whether behavioral flexibility and simpleand complex-rule learning performance can be predicted by foraging ecology. We predict faster learning and higher flexibility in animals hunting in mor...

background : the aim of this study was to evaluate the performance of water ozonation on disinfection by-product formation. methods : experiments were carried out on samples taken from tajan river, mazandaran province, iran. samples of the pre-filtered raw water and from the 3.5-l water tank reservoir (wt) were analyzed for uv-254 absorbance, dissolved organic carbon (doc), hs and non-hs, chlor...
