The hydrodynamic/water quality model is an important tool in water environment management. It used to gain a deeper understanding of physical, chemical, and biological processes develop models capable represent surface waters with realism. A hydrodynamic can give essential data sediment, noxious, eutrophication modelling. Models enable decision-makers select alternatives for management that are...
The Hawkesbury-Nepean River (HNR) system in South-Eastern Australia is the main source of water supply for the Sydney Metropolitan area and is one of the more complex river systems due to the influence of urbanisation and other activities in the peri-urban landscape through which it flows. The long-term monitoring of river water quality is likely to suffer from data gaps due to funding cuts, ch...
Original scientific paper Studies on the evolution of paleo-channels in coastal areas are important for submarine engineering construction and to reveal changes in the global paleoenvironment. Thus, to explore the characteristics of paleo-channels during the late Last Glaciation in the western South Yellow Sea, digital terrain analysis method and ArcGis river extraction function were employed, ...
land use effects on heavy metal pollution of river sediments in guilan, southwest of the caspian sea
studies have showed the river siahroud is the main contributor to the present pollution of anzali wetland in guilan. therefore, this study was initiated to evaluate the spatial distribution of metals pollution on the river siahroud sediments in guilan.surfacial river sediment samples along this river were taken during five consecutive seasons at eight sampling stations and analyzed for availabi...
Information on erosion and capacity of sediment carrying condition in various basins is one of the subjects that in each of hydrology and river engineering projects should be considered. In the present study HEC-RAS model was applied to evaluate and predict the sedimentation and erosion in the reach of Talar River with 12 km length. For doing this study 40 cross section which was surveyed ...
Increasing frequency and severity of flooding demands identification of flood hazard zones in Kalilangan, Bukidnon in response to the echoing need of better disaster preparedness via enhancing the understanding and awareness of the public on flood characteristics by integrating the use of two-dimensional hydrodynamic modeling and remote sensing. Flood simulation was carried out in a two-dimensi...
BACKGROUND Renin-angiotensin system inhibitors (RAS inhibitors) are antihypertensive agents with potential antitumor effects. However, various studies have yielded conflicting results on the influence of RAS inhibitors on survival of cancer patients. The aim of this study was to evaluate the effect of RAS inhibitors on recurrence, metastasis, and survival in cancer patients through a meta-analy...
Historical DNA of museum specimens is paramount importance in elucidation complex nomenclature issues and a priceless source material gathered during preceding centuries hardly accessible today sites. Here we report the results genotyping type Lemmus obensis bungei Vinogradov, 1925 from collection Zoological Institute RAS lemmings upper streams Omolon River, identified as L. amurensis Systemati...
EXTRACT Although there are new ways to portray the brain, colored and computerized encephalography but Coma is still unknown and such as death remain beyond comprehension and knowing. Is not it ? Perhaps because of this, despite knowing that some part of the brain is not yet fully understood all its parts. But knowing the components that working to each other is key for discovering a lot of...
