Investigation of the waves generated by underwater disturbances gives precious insight into the effect of man-made underwater explosions as well as natural phenomena, such as underwater volcanoes or oceanic meteor impact. On the other hand, prediction of the effects of such waves on the coastal installations and structures is required for preparation worthwhile criteria for coastal engineers to...

the aim of this study is to investigate underground water quality parameters in gorganrud river basin and their connection with aboveground conditions using gis and artificial neural networks. in order to prepare a land use map of the area, liss iii image of irs satellite of the year 2008 was used in a maximum likelihood classification. the results revealed that there was a significant correlat...

Rapid development and population growth have resulted in an ever-increasing level of water pollution in Malaysia. Therefore, this study was conducted to assess water quality of Selangor River in Malaysia. The data collected under the river water quality monitoring program by the Department of environment from 2005 to 2015 were used for statistical analyses. The local water quality indices were ...

How salts affect water structure is an important topic in many research fields. Salt-water clusters can be used as model systems to extract interaction information that is difficult to obtain directly from bulk solutions. In the present study, integrated tempering sampling molecular dynamics (MD) are combined with quantum mechanics (QM) calculations to overcome the sampling problem in cluster s...

in our current study, supercritical water impregnation (scwi) was introduced as a unique catalyst preparation method by employing the high diffusivity property of supercritical water. the method allows nano-particles to place on support surfaces in extremely dispersed conditions. the silica-based nanocatalyst granules for this purpose were prepared by initial impregnation of highly porous silic...

  All desalination methods which are currently used have limitations. A newly designed instrument by Zare A.M. was tested and compared with currently used method in Razi Vaccine and Serum Research Institute(RVSRI). Samples of anti snake venom for desalination was provided by department of anti-serum, RVSRI. Parameters included in this study were time and water consumption during desalination pr...

The unsmooth boundary will greatly affect motion morphology of a shallow water wave, and a fractal space is introduced to establish a generalized KdV-Burgers equation with fractal derivatives. The semi-inverse method is used to establish a fractal variational formulation of the problem, which provides conservation laws in an energy form in the fractal space and possible solution structures of t...
