Improved pretreatments applied to the sugarcane bagasse and release of lignin and hemicellulose from the cellulose-enriched fractions by sulfuric acid hydrolysis
(2014)
BACKGROUND A number of pretreatments have been reported in the literature aiming to improve yields with increases in degree of digestibility of the cellulose-enriched fractions, in reducing the process time recalcitrance ...
Responses of the Phytoplankton Community of a Tropical Reservoir (São Paulo, Brazil) to the Enrichment with Nitrate, Phosphate and EDTA
(1983-01-01)
The effects of artificial enrichment with nitrate, phosphate and EDTA on the phytoplankton community were studied in the Lobo Reservoir (São Paulo, Brazil). After 14 days of in situ incubation, the amounts of suspended ...
Sub-lethal combined effects of illicit drug and decreased pH on marine mussels: A short-time exposure to crack cocaine in CO2 enrichment scenarios
(2021-10-01)
The increasing CO2-concentrations in the atmosphere promote ocean acidification. Seawater chemistry changes interact with contaminants, such as illicit drugs in the coastal zones. This work evaluates impacts of pH decrease ...
Model-data synthesis for the next generation of forest free-air CO2 enrichment (FACE) experiments
(Wiley-Blackwell, 2016-01-01)
The first generation of forest free-air CO2 enrichment (FACE) experiments has successfully provided deeper understanding about how forests respond to an increasing CO2 concentration in the atmosphere. Located in aggrading ...
Increase on incineration capacity and NOx control for air enrichment in the experimental simulation of aqueous residue incineration
(Taylor & Francis Ltd, 2004-07-01)
An experimental investigation of air enrichment in a combustion chamber designed to incinerate aqueous residues is presented. Diesel fuel and liquefied petroleum gas (LPG) were used independently as fuels. An increase of ...
