Expressed sequence tags from Atta laevigata and identification of candidate genes for the control of pest leaf-cutting ants.
(2011-06-17)
Leafcutters are the highest evolved within Neotropical ants in the tribe Attini and model systems for studying caste formation, labor division and symbiosis with microorganisms. Some species of leafcutters are agricultural ...
Elucidating capacitance and resistance terms in confined electroactive molecular layers
(2013-01-02)
Electrochemical analyses on confined electroactive molecular layers, herein exemplified with electroactive self-assembled monolayers, sample current contributions that are significantly influenced by additional nonfaradaic ...
Oxidation of chalcopyrite by Acidithiobacillus ferrooxidans and Acidithiobacillus thiooxidans in shake flasks
(Elsevier B.V., 2002-12-02)
Chalcopyrite oxidation was evaluated with two acidophilic thiobacilli that are important in bioleaching processes. Acidithiobacillus thiooxidans in pure culture did not oxidize CuFeS2 but oxidized externally added S in the ...
Estudo das propriedades eletroquímicas e magnéticas do polipirrol
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Química - PPGQ, 2010-11-22)
In this work the electrochemical degradation of polypyrrole films was studied by means of an applied overpotential and the magnetic properties of polypyrrole pellets, when these were modified by the incorporation of metallic ...
Reduction of adaptation to high-energy diets using virginiamycin: effects on ruminal fermentation
(Wageningen Acad Publ, 2019-01-01)
The objective of this study was to evaluate the reduction of adaptation length to high-energy diets to cannulated Nellore cattle using Virginiamycin (VM) as feed additive, in which the following variables were assessed: ...
Producción de oxihidrógeno como alternativa energética.

Biodegradation and Phytotoxicity of Biodiesel, Diesel, and Petroleum in Soil
(Springer, 2014-05-01)
The study aimed to investigate the biodegradation of contaminated soil with biodiesel, diesel, and petroleum by autochthonous soil microorganisms and also enriched with Bacillus subtilis by means of colorimetric method. ...
Changes in the phytoplankton structure downstream a large reservoir: effects of tributaries on the assemblages attributes
(Walter De Gruyter Gmbh, 2015-03-01)
Changes in richness, diversity, evenness and abundance of phytoplankton in relation to environmental variables and tributary entrances were studied along 30 km of the Parana River downstream Itaipu Reservoir. A high number ...
An impedimetric biosensor to test neat serum for dengue diagnosis
(Elsevier B.V., 2015-07-05)
NS1, a non-structural dengue protein, has been used as a biomarker for the detection of viremia in dengue diagnosis. In this work, an impedimetric label-free immunosensor based on an anti-NS1 modified gold electrode was ...
Hydrochemical and stable isotopes (H, O, S) signatures in deep groundwaters of Parana basin, Brazil
(Springer, 2015-01-01)
This paper describes a hydrochemical (major and trace elements) and stable isotopes (H, O, S) study of rainwater and groundwater in a Guarani Aquifer System (GAS) transect at Sao Paulo State, Brazil. The Brazilian Code of ...
