Microbially induced calcium carbonate precipitation is one of the biomineralization types closely dependent on the parameters of the microenvironment. Minerals are precipitated as a product of environmental and bacterial cell interactions, however, this system has very little control via microorganisms. The aim of research was to determine the influence of abiotic factors (pH, temperature, agit...
Due to the spread of bluetongue (BT) in Europe in the last decade, a sentinel surveillance programme was initiated for Switzerland in 2003, consisting of serological sampling of sentinel cattle tested for BT virus antibodies, as well as entomological trapping of Culicoides midges from June until October. The aim of this study was to create a 'suitability map' of Switzerland, indicating areas of...
The investigation of electric arc furnace (EAF) steel slag as a viable add-on technology to existing stormwater systems for the removal of dissolved phosphorus (P) was extended to explore the effects of varying environmental and treatment system conditions. Parameters such as stormwater composition, P concentration, metal concentration, pH, temperature, slag mass and slag particle size were var...
asphaltene instability is one of the major problems in gas injection projects throughout the world. numerous models have been developed to predict asphaltene precipitation; the scaling equation is an attractive tool because of its simplicity and not involving complex properties of asphaltene. in this work, a new scaling model is presented to account for asphaltene precipitation due to gas inje...
With the deployment of the WSR-88D weather radar, the National Weather Service will provide improved estimates of hourly precipitation accumulations for most of the United States on roughly a 4 by 4 km grid. This information will be used as input to operational hydrologic models to improve streamflow prediction for flood forecasting and water resources management. A critical issue that hydrolog...
The global spread of highly pathogenic avian influenza H5N1 in poultry, wild birds and humans, poses a significant panzootic threat and a serious public health risk. An efficient surveillance and disease control system requires a deep understanding of their spread mechanisms, including environmental factors responsible for the outbreak of the disease. Previous studies suggested that H5N1 viruse...
A statistical approach to behavioral modeling for assessing dynamic metrological performance during the concept design of accurate digitizers is proposed. A surface-response approach based on statistical experiment design is exploited for avoiding unrealistic hypothesis of linearity, optimizing simulation, exploring operating conditions systematically, as well as verifying identification and va...
Article history: Received 8 January 2014 Received 30 April 2014 Accepted 30 April 2014 Available online 16 October 2014 Climate change is supposed tohave influences onwater quality and ecosystem.However, only few studies have assessed the effect of climate change on environmental toxic contaminants in urban lakes. In this research, response of several toxic contaminants in twelve urban lakes in...
Global change is challenging plant and animal populations with novel environmental conditions, including increased atmospheric CO(2) concentrations, warmer temperatures, and altered precipitation regimes. In some cases, contemporary or "rapid" evolution can ameliorate the effects of global change. However, the direction and magnitude of evolutionary responses may be contingent upon interactions...
Hydrological modeling is an important tool used for basin management and studying the impacts of extreme events in a river basin. In streamflow simulations, precipitation plays essential role hydrological models. Meteorological satellite measurement techniques provide highly accurate rainfall information with high spatial temporal resolution. this analysis, tropical monitoring mission (TRMM) 3B...
