WIND DRIVEN WAVES' ENERGETIC POTENTIAL ASSESSMENT ON BRAZILIAN SOUTH-SOUTHEASTERN COAST

open access: yesRevista Mundi Engenharia, Tecnologia e Gestão (ISSN: 2525-4782), 2018
The electrical energy demand is constantly growing, making the study of new energy sources necessary. The worries about climate change make it almost mandatory that these sources are renewable. The ocean is a vast source of energy that is not yet fully exploited. With this in mind, for this paper, wind generated waves were simulated along the Brazilian

Black carbon contents and distribution in sediments from the southeastern Brazilian coast (Guanabara Bay) [PDF]

open access: yesJournal of the Brazilian Chemical Society, 2008
The concentration of black carbon (BC), as well as the relative contribution of BC to total organic carbon, was determined for the first time in sediments from Guanabara Bay. BC was quantified by a thermal oxidation method (CTO-375) and total organic carbon by dry oxidation.
