The result of wind dynamic (capacity and potential) is transport of soil or sediment particles and subsequent formative desert landforms based on the severity of erosion or sedimentation. The Khartouran region, because of its geology, geomorphology and climatology conditions is a special place in the arid region on the closed basin of Dasht-e-kavir. It is evident that the ecosystem balance of t...

Acinetobaclet glutaminase-asparaginase has been shown to consist of 4 subunits (molecular weight 33,000) by sedimentation equilibrium in 5.5 M guanidine HCl and electrophoresis in sodium dodecyl sulfate on polyacrylamide gels after cross-linking the protein with dimethyl suberimidate. Moving boundary velocity experiments showed that most of the native enzyme sediments as the tetramer (SZO+ = 7....

Background and objectives The primary objective of drilling at Site U1345 was to study high-resolution HoloceneLate Pleistocene paleoceanography at a proximal gateway location to the Arctic Ocean at a water depth of ~1008 m. The drill site is located on an interfluve ridge near the large and broad head of Navarin Submarine Channel off the Bering Sea Shelf. It is anticipated to receive ample sup...

A sedimentological study after the flash floods that hit North Luwu on July 13, 2020, has been carried out three affected rivers, namely Masamba River, Radda and Binuang River. The aims to determine impact of 2020 flood disaster, including sedimentation rate, annual bedload sediment volume, total sediments, which will be used as a reference for future mitigation consideration. is based fieldwor...

The effects of herbivorous zooplankton on the sedimentation of particles out of the euphotic zone are examined with mathematical models, a large-scale field experiment, and descriptive data from a eutrophic lake. The theory is rooted in the population dynamics of phytoplankton and zooplankton and so explicitly accounts for the potential effect of zooplankton grazing on primary production and th...

The analysis of IRS 1A satellite imagery has indicated the existence of two NE SW trending sub parallel faults along which the coast is undergoing land subsidence as revealed by the concavity in the shore line, preferential migration of the river systems and the drainage congestion, absence of beach ridges, occurrence of off shore shoal etc. The study has further indicated chains of tectonicall...
