In this work a particle-tracking model was implemented and applied to simulate the instantaneous injection of a dye tracer in the Setubal Lagoon, Santa Fe, Argentina. It focused on the study of the water quality problem generated in point sources of contaminated water through a rainfall drainage system. This problem is difficult to treat with the so-called Eulerian methods. The interpolation fo...

We present an overview of an ongoing project to build a DDDAS for identifying and tracking chemicals in water. The project involves a new class of intelligent sensor, building a library to optically identify molecules, communication techniques for moving objects, and a problem solving environment. We are developing an innovative environment so that we can create a symbiotic relationship between...

Free-ling amoebae (FLA) including Acanthamoeba spp., Naegleria fowleri, Balamuthia mandrillaris and Sappinia pedata, can cause opportunistic infections leading to severe brain pathologies. Human infections with pathogenic FLA have been increasingly documented in many countries. In Switzerland, thus far, the occurrence and distribution of potentially pathogenic FLA has not been investigated. Swi...

The EU-water framework directive aims at nutrient reductions, since anthropogenically induced eutrophication is a major threat for coastal waters. However, phytoplankton biomass in southern Baltic Sea coastal water bodies (CWB) remains high and the underlying mechanisms are not well understood. Therefore, a CWB data set was analysed regarding changes in phytoplankton biomass and nutrient concen...

The microcrustacean Dunhenvedia odontoplax (Figure 1), which belongs to the sub-famíly Aloninae (Cladocera Chydoridae), occurs commonly in Neotropical freshwater (Smirnov, 1996). In Brazil, it was first reported in São Paulo State by Sars (1901), and later in the states of Roraima, by Smirnov and Santos-Silva (1995), Pernambuco, by Brehm (1937, 1938) and Rio Grande do Sul, by Montú and Gloeden ...

heavy metals and dyes are major contributors in contamination of water streams. these contaminants enter into our eco- system, thus posing a significant threat to public health, ecological equilibrium and environment. thus a combined discharge of these contaminants results in water pollution with high chemical oxygen demand, biological oxygen demand, color, particulate matter, suspended particl...

Stromatal fruiting bodies of Cordyceps cardinalis were successfully produced in cereals. Brown rice, German millet and standard millet produced the longest-length of stromata, followed by Chinese pearl barley, Indian millet, black rice and standard barley. Oatmeal produced the shortest-length of fruiting bodies. Supplementation of pupa and larva to the grains resulted in a slightly enhanced pro...

The purpose of this study is to evaluate a remote sensing method for real time monitoring of wastewater effluent. Reflectance in the range from 400 to 950 nm with a spectral resolution of 2 nm, simultaneously with turbidity, chlorophyll and total suspended matter contents were acquired in two wastewater systems: RUm and Naan, Israel. The reflectance spectra of wastewater effluent were investiga...

The cyanobacteria are a phylum of bacteria that have played a key role in shaping the Earth's biosphere due to their pioneering ability to perform oxygenic photosynthesis. Throughout their history, cyanobacteria have experienced major biogeochemical changes accompanying Earth's geochemical evolution over the past 2.5+ billion years, including periods of extreme climatic change, hydrologic, nutr...
