Impact of pervious pavement in urban areas on catchment basin recovery
Santos, Cristiano de Assumpção; Frigo, Elisandro Pires; Frigo, Késia Damaris de Azevedo; Eckert, Caroline Thaís; Dieter, Jonathan; Alves, Helton JoséUrbanization and disorderly occupation of urban areas have created several environmental problems, such as floods. Among the main causes of these problems is soil sealing associated with urban sprawl. Impervious surfaces provide less precipitation to recharge catchment basins by diverting water that should be restored in that region to other basins. This study compares two existing paving systems: concrete pave...
Optimization of first generation alcoholic fermentation process with Saccharomy...
Bonassa, Gabriela; Schneider, Lara Talita; Cremonez, Paulo André; Oliveira, Carlos de Jesus de; Teleken, Joel Gustavo; Frigo, Elisandro PiresThe influence of variables that affect the process of alcohol fermentation for the optimization of ethanol production is evaluated, with fermentation time, final substrate concentration, cells and ethanol as performance indexes. A statistical planning for process optimization was employed by analyzing three independent variables: temperature, pH and Brix and the influence they have on dependent variables. Brix ...
