The Gulf of Papagayo at the northern Pacific coast of Costa Rica experiences pronounced seasonal changes in water parameters caused by wind-driven coastal upwelling. While remote sensing and open water sampling already described the physical nature of this upwelling, the spatial and temporal effects on key parameters and processes in the water column have not been investigated yet, although bei...

Renewable energy, water conservation, and environmental protection are the most important challenges today. Osmotic membrane bioreactor (OMBR) is an innovative process showing superior performance in bioenergy production, eliminating contaminants, low fouling tendency. However, salinity build-up main drawback of this process. Identifying microbial community can improve production contaminant tr...

Wastewater causes significant environmental harm. Researchers have created a variety of approaches to address this issue. In study, phytoremediation technology was used remove pollutants from wastewater so that it could be for other purposes. This is one the most promising because inexpensive, ecologically benign, and effective at removing pollutants. Using methodical mapping approach, aquatic ...

Life cycle assessment (LCA) was performed in dairy buffalo farms representative of Southern Italian farming systems, similar due to several characteristics, with the exception wheat production. This work evaluated impacts derived from this management choice, comparing crop (WWC) or not (NWC). In agreement literature, economic allocation chosen as a useful strategy attribute equivalents by-produ...

En este estudio evaluamos las microalgas Chlorella vulgaris y Demodesmus asymmetricus, con el fin de determinar la proporción que remueven mayor concentración nitrógeno fósforo en aguas residuales una planta tratamiento. Se realizó un diseño mezclas agua residual durante 9 días, fotoperiodo 12:12 h, invernadero. Las mayores eficiencias remoción (principalmente NO3--N NO2--N) (PO43-) se observar...

Early detection of fish diseases and identifying the underlying causes are crucial for farmers to take necessary steps mitigate potential outbreak thus avert financial losses with apparent negative implications national economy. Typically, caused by viruses bacteria; according biochemical studies, presence certain bacteria may affect level pH, DO, BOD, COD, TSS, TDS, EC, PO43-, NO3-N, NH3-N in ...
