Landscape evolution in the Guañacos fold and thrust belt (37° S): Insights from geomorphological and morphometric analysis
(Pergamon-Elsevier Science Ltd, 2021-11)
The Guañacos fold and thrust belt, in the northern Neuquén Andes (37°-38°S; 70°30′-71°10′W), has been studied by many researchers focusing on the Quaternary tectonic activity, from a morphological to a structural perspective. ...
Quantificação de resíduos recicláveis na drenagem urbana do Lago Igapó I em Londrina - PR
(Universidade Tecnológica Federal do ParanáLondrinaBrasilEngenharia AmbientalUTFPR, 2021-12-17)
The inadequate disposal of solid waste in developing countries is a matter of concern, since the inadequate disposal in vacant lots, places close to water courses impede the flow of the urban drainage system and cause ...
The effects of tree establishment on water and salts dynamics in naturally salt-affected grasslands
(Springer, 2007-03)
Plants, by influencing water fluxes across the ecosystem–vadose zone–aquifer continuum, can leave an imprint on salt accumulation and distribution patterns. We explored how the conversion of native grasslands to oak ...
Sistema de leito de drenagem e sedimentador como solução para redução de volume de lodo de decantadores e reuso de água de lavagem de filtros.
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Engenharia Urbana - PPGEU, 2004-02-27)
Water supply systems utilize, in most cases, conventional Water
Treatment Plants (WTPs). These plants use alum and ferric salts in their coagulation
process, and produce residues (sludge) mainly in filter systems and ...
Influence of Biliary Drainage on the Repair of Hepatic Lesions in Biliary Fibrosis
(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2011)
Background. Bilioduodenal (BD) and biliojejunal (BJ) derivation induce enterobiliary reflux and bile stasis. Decompression of the excluded loop of the Roux-en-Y (BJD) was proposed to minimize these effects. The aim of this ...
Increased energy cogeneration in the sugar-energy sector with the use of sugarcane straw, electrification of drives, and high-drainage rollers in the extraction
(2020-03-01)
The sugar-energy sector stands out in the production of electrical energy in the Brazilian energy matrix. The updating of Law 9,427 allowed increasing the limit of power injected in the transmission or distribution systems ...
Observations and assessment of iron oxide and green rust nanoparticles in metal-polluted mine drainage within a steep redox gradient
(CSIRO, 2014)
In this study of iron- and silica-bearing nanoparticle and colloid aggregates in slightly acidic mine drainage, we combined bulk scale geochemistry techniques with detailed nanoscale analyses using high-resolution transmission ...
Manejo de canola em terras baixas: características do dossel, interceptação da radiação e produtividade de grãos
(Universidade Federal de Santa MariaBrasilAgronomiaUFSMPrograma de Pós-Graduação em AgronomiaCentro de Ciências Rurais, 2021-08-27)
The modification of microclimatic conditions in agricultural crops can substantially affect the growth and yield of grains in waterlogged environments. Therefore, the present study aimed to determine the effect of the ...
