Construction of Reservoir dams on the river, in addition to change and decrease the river’s regime in downstream, cause environmental problems for ecosystems. This issue can be more severe by dumping pollution into rivers. Therefore, estimating the minimum environmental flow for river systems and other aquatic ecosystems is necessary to keep environment and water resources. In this study, the e...
Autonomous navigation of mobile robots through unstructured terrain presents many challenges. The task becomes even more difficult with increasing obstacle density, at higher speeds, and when a priori knowledge of the terrain is not available. Reactive navigation schemas are often dismissed as overly simplistic or considered to be inferior to deliberative approaches for off-road navigation. The...
Rainfall-Runoff simulation is one of the main subject of hydrology and environmental management. Therefore, researchers are constantly interested in finding new ways to solve this problem and modify existing models or modeling methods. However, the lack of statistics and information from the poor development of hydrological networks has always been a major problem in countries that facing finan...
RESUMO Na Parte I deste artigo, o autor explicou as dificuldades em alcançar a acurácia dos diagnósticos de enfermagem, a relevância do pensamento crítico no alcance dessa acurácia e as mais novas perspectivas desse pensamento. Na Parte II, as dimensões do pensamento crítico identificadas como importantes para a prática de enfermagem são aplicadas em um estudo de caso de uma menina de 16 anos c...
Sedimentation and consolidation of cohesive sediments near the dam body can cause many problems such as clogging the bottom outlets and entering the sediments into the hydropower intakes. Flushing of these sediments through the bottom outlet will be successful only if the hydraulic conditions are designed according to the physical and mechanical properties of consolidated sediments. During the ...
Morbid obesity is an increasingly common problem worldwide6, and therefore, there is increasing utilization of surgical procedures for the treatment of this disease5. One of the preferred techniques is the Roux-en-Y gastric bypass. This technique which generally leads to rapid weight loss is associated with the formation of biliary calculi and consequently to its complications (e.g., acute panc...

a survey on endo-parasitic infections on barboid fishes of south- west of iran (khouzestan province) was carried out from spring 2007 to atumn 2009. altogether 296 specimens from five different fish species were examined, they are barbus grypus heckel, 1843; barbus sharpeyi günther, 1874; barbus esocinus heckel, 1843; barbus barbulus heckel, 1849 and barbus pectoralis heckel 1843. the fishes we...
Using the best management strategies (BMPs) is a useful way to control pollutions at the watershed outlets, which, of course, requires spending costs. Prioritizing these strategies (especially in areas with scarce resources) will greatly contribute to the efficiency and adequacy of these methods in terms of reducing pollution and their application in critical areas. In this research, the SWA...
