Narrativas da mobilidade: comunicação, cultura e produção em espaços informacionais

This research stems from the issue of the mobility phenomenon, through the pathway tread by subjects in need of connection and access to uninterrupted information flow. In this informational, cultural and technological context, the presence of mobile dispositives stands out, especially cell phones. Such artifacts, which contain not only voice services, but texting information, and Internet conn...

Waste utilization and biodiesel production by the green microalga Scenedesmus obliquus.

Scenedesmus obliquus was cultivated in three types of waste discharges to couple waste treatment with biodiesel production. The lipid pool accumulation was boosted to 1.0 g liter(-1) against 0.1 g liter(-1) for the control. The waste-grown S. obliquus showed an increase in the content of the saturated fatty acid pool, which is desirable for good-quality biodiesel.

Outdoor Cultivation of the Biodiesel Promising Microalga Scenedesmus obliquus in Municipal Wastewater: A Case Study

Despite the promising research findings on microalgae as a feedstock for biodiesel, reduction of its production cost is still a challenge. One possible solution to overcome this problem is outdoor biomass production using wastewater as a growth medium. The present study aimed to evaluate the climate key parameters for Scenedesmus obliquus outdoor biomass production during different seasons, as ...
