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...

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...

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...

Settings in which independent self-interested agents form connections with each other are extremely common, and are usually modeled using network formation games. We study a natural extension of network formation games in which the nodes cannot form connections themselves, but instead must do it through an intermediary, and must pay the intermediary to form these connections. The price charged ...
