This research aims is the agroindustrial wastewater treatment by an electrochemical device called Microbial Fuel Cell (MFC), which produces electricity while to metabolize the wastewater. The behavior of biofilme formed at reticulated carbon vitreous/Shewanella putrefaciens/vinasse solution interface as anode, was studied by electrochemical measurements. The polarization curves against the carb...

textile wastewater contains substantial pollution loads in terms of chemical oxygen demand (cod), biological oxygen demand (bod), total suspended solids (tss), total dissolved solids (tds) and heavy metals. phytoremediation used for removing heavy metals and other pollutants by aquatic macrophytes treatment systems (amats) is well established environmental protective technique. a lab scale stud...

We consider the maximum covering problem, a combinatorial optimization problem that arises in many facility location problems. In this problem, a potential facility site covers a set of demand points. With each demand point, we associate a nonnegative weight. The task is to select a subset of p > 0 sites from the set of potential facility sites, such that the sum of weights of the covered deman...

Hodnotenie a charakterizácia vybraných škodlivín v prípade zdrojov povrchovej vody High quantities of organic matter can reduce the chemical and biological quality of river water. The key indicator of the oxygenation status of water bodies is the biological oxygen demand (BOD) and ammonium. These are main indicators for the water quality classification. Although countries have different river c...

Stakeholders in the science system need to decide where to place their bets. Example questions include: Which areas of research should get more funding? Who should we hire? Which projects should we abandon and which new projects should we start? Making informed choices requires knowledge about these research options. Unfortunately, to date research portfolio options have not been defined in a c...

Climate change is expected to decrease heating demand and increase cooling demand for buildings and affect outdoor thermal comfort. Here, we project changes in residential heating degree-days (HDD) and cooling degree-days (CDD) for the historical (1981-2010) and future (2080-2099) periods in the United States using median results from the Climate Model Intercomparison Project phase 5 (CMIP5) si...

An accurate prediction of prospective construction supply and demand, especially the private residential market, is paramount important to policy makers, as it could help formulate strategies to cultivate/stabilize the economy and satisfy the social needs (at macro level). Despite that, a realistic prediction of future private residential demand is never an easy task, as it is governed by a num...

A Balance between the demand and supply is one of the indicator of the position of your organization in the Market. Every organization tries to match their supply with the demand. However, balancing between the two is highly impossible because of the changing customer requirements. Retail stores whose customer are the end users is very dynamic system as it is prone to the fluctuations immediate...

W consider a repeated newsvendor problem in which the decision maker (DM) does not have access to the underlying demand distribution. The goal of this paper is to characterize the implications of demand censoring on performance. To that end, we compare the benchmark setting in which the DM has access to demand observations to a setting in which the DM may only rely on sales data. We measure per...
