HIGHLIGHTS • A strain of Penicillium citreosulfuratum was isolated from corroded metal. The fungus formed biofilm on the surface aluminum wire. This grew in presence 50 mM Al3+ liquid medium. Thyme, oregano, and melaleuca essential oils inhibited this growth.

The region of Volta Grande do Xingu River, in the state of Pará, presents several kinds of land use ranging from extensive cattle farming to agroforestry, and deforestation. Currently, the Belo Monte Hydroelectric Power Plant affects the region. We present a checklist of amphibians and reptiles of the region and discuss information regarding the spatial distribution of the assemblies based on r...

In Brazil, hydroelectricity represents close to 70% of the energy consumed in country. However, hydroelectric plant operations may be affected by deposit sediments for erosive processes on reservoir margins. This study presents results implementing two semi-rigid erosion control techniques installed margins Brazilian Hydroelectric Power Plants (HPPs). These were gabion and mattress used as a mi...

Optimal operation of water resources in multiple and multipurpose reservoirs is very complicated. This is because of the number of dams, each dam's location (Series and parallel), conflict in objectives and the stochastic nature of the inflow of water in the system. In this paper, performance optimization of the system of Karun and Dez reservoir dams have been studied and investigated with the ...

Environmental pollution and rapid depletion are among the chief concerns about fossil fuels such as oil, gas, and coal. Renewable energy sources do not suffer from such limitations and are considered the best choice to replace fossil fuels. The present study develops a mathematical model for optimal allocation of regional renewable energy to meet a country-wide demand and its other essential as...
