1. Distribuição da temperatura da superfície do mar e dos sedimentos suspensos na plataforma continental capixaba utilizando imagens landsat 5/TM
O monitoramento da qualidade da água nas regiões internas à Plataforma Continental (PC) apresenta-se dispendioso quando são usados métodos convencionais. O Sensoriamento Remoto Orbital apresenta-se como uma ferramenta alternativa ao monitoramento de variáveis importantes como a Temperatura da Superfície do Mar (TSM) e a Concentração de Sedimentos em

2. Transferência de metano no sentido gás-líquido com vistas ao atendimento da demanda carbonácea da desnitrificação de esgoto sanitário
This work presents a simulation of a hybrid system for waste water treatment, in order to explain the possible use of a carbon supply on denitrification from the methane produced in an anaerobic reactor and transferred to the liquid mass of a reactor that would be removing nitrogen. It was used the biogas produced in a UASB reactor, that passed through a sto

3. Denitrification, Acetylene Reduction, and Methane Metabolism in Lake Sediment Exposed to Acetylene
Samples of sediment from Lake St. George, Ontario, Canada, were incubated in the laboratory under an initially aerobic gas phase and under anaerobic conditions. In the absence of added nitrate (NO3−) there was O2-dependent production of nitrous oxide (N2O), which was inhibited by acetylene (C2H2) and by nitrapyrin, suggesting that coupled nitrification-den

4. Partitioning Effects during Terminal Carbon and Electron Flow in Sediments of a Low-Salinity Meltwater Pond near Bratina Island, McMurdo Ice Shelf, Antarctica
A study of anaerobic sediments below cyanobacterial mats of a low-salinity meltwater pond called Orange Pond on the McMurdo Ice Shelf at temperatures simulating those in the summer season (<5°C) revealed that both sulfate reduction and methane production were important terminal anaerobic processes. Addition of [2-14C]acetate to sediment samples resulted in
