The damming of a river causes dangerous consequences on structure of the environment downstream of the dam, modifying the sediment composition, which impose major adjustments in longitudinal distribution of benthic community. The construction of Engenheiro Sérgio Motta Dam in the Upper Paraná River has caused impacts on the aquatic communities, which are not yet fully known. This work aimed to ...
China's historiographical traditions tell of the successful control of a Great Flood leading to the establishment of the Xia dynasty and the beginning of civilization. However, the historicity of the flood and Xia remain controversial. Here, we reconstruct an earthquake-induced landslide dam outburst flood on the Yellow River about 1920 BCE that ranks as one of the largest freshwater floods of ...
The simulation of damage process of high arch dam subjected to strong earthquake shocks is significant to the evaluation of its performance and seismic safety, considering the catastrophic effect of dam failure. However, such numerical simulation requires rigorous computational capacity. Conventional serial computing falls short of that and parallel computing is a fairly promising solution to t...
The design of a gravity dam is performed through an interactive process involving a preliminary layout of the structure followed by a stability and stress analysis. This study presents a method to define the optimal top width of gravity dam with genetic algorithm. To solve the optimization task (minimize the cost of the dam), an optimization routine based on genetic algorithms (GAs) was impleme...
Along with the development of virtual reality (VR) technology, simulation system as a new perspective of management methods and technical means in the progress of the project management plays an increasingly important role. This paper presents a Virtools-based visual simulation method and realizes a concrete dam pouring process. It proposes that the mode of the dam for a certain period could be...
Abstract : Way Sekampung Dam is built to optimize the utilization of watershed. It classified as an embankment dam with upright core which following a high risk failure. The research slope stability become effort fulfill safety. This study based on effects seepage and seismicity. review focused what safety against potential piping, while for seismicity it carried out under earthquake loading us...
Edwardsiella tarda is a serious aquaculture pathogen that can infect many cultured fish species. The aim of this study was to investigate the potential importance of DNA adenine methylase (Dam) in E. tarda pathogenesis. The E. tarda dam gene (dam(Et)) was cloned from a pathogenic strain, TXD1, isolated from diseased fish. Dam(Et) shares high (70.2%) sequence identity with the Dam proteins of Ye...
Rubber dam is considered an ideal device for tooth isolation. Nevertheless, its usage is quite rare in the Czech Republic. The aim of this study was: firstly, to gather and evaluate information regarding the use of rubber dam by dentists in the Czech Republic and to compare it with other countries; secondly to find out whether there are any influencing factors as to rubber dam usage; and finall...
