Histórico da aplicação de vinhaça em canaviais: bioensaios de toxicidade terrestre e aquática
(2019-12-29) [Tese de doutorado]
A vinhaça, um dos principais resíduos gerados na transformação da cana-de-açúcar em etanol, possui potencial poluidor, frente ao alto volume produzido e por suas características físico-químicas. A contaminação de lagos e ...
Chromosomal polymorphism in 12 populations of Mikania micrantha (Compositae)
(Genetics and Molecular Biology, 1999-09-01) [Artigo]
Mikania micrantha é uma planta herbácea perene, da família Asteraceae, amplamente distribuída através de todo o continente americano. No Brasil, M. micrantha tem distribuição irrestrita, ocupando os mais variados ambientes, ...
Ecologia de metapopulações e metacomunidades de bromélias atmosféricas
(2019-02-08) [Tese de doutorado]
Bromélias atmosféricas são cerca de 300 espécies do gênero Tillandsia que geralmente compõem o grupo de epífitas vasculares dominante das porções mais altas e externas dos dosséis florestais do continente americano. Diversas ...
Effects of physical training with different intensities of effort on lipid metabolism in rats submitted to the neonatal application of alloxan
(Lipids in Health and Disease, 2012-10-15) [Artigo]
Background: Type 2 diabetes mellitus (T2DM) is a chronic disease that is characterized by insulin resistance. Its development is directly connected with the inability of insulin to exert its action, not just on carbohydrate ...
Morphological Changes in Poly(Caprolactone)/Poly(Vinyl Chloride) Blends Caused by Biodegradation
(Journal of Polymers and the Environment, 2010-03-01) [Artigo]
The biodegradation of blends of poly(caprolactone) (PCL) and poly(vinyl chloride) (PVC) has been studied. Blends of composition PCL/PVC 1:1 and 1:2 w/w were tested. The 1:1 blend contained crystals in the as-cast state and ...
Fructose-rich diet leads to reduced aerobic capacity and to liver injury in rats
(Lipids in Health and Disease, 2012-06-19) [Artigo]
The main purpose of this research was to investigate the alterations in the aerobic capacity and appearance of metabolic alterations in Wistar rats fed on fructose-rich diet. We separated twenty-eight rats into two groups ...
Endophytic microorganisms from coffee tissues as plant growth promoters and biocontrol agents of coffee leaf rust
(Biological Control, 2012-10-01) [Artigo]
A total of 234 strains of endophytic bacteria (217) and fungi (17) from coffee tissues were evaluated for their potential to control coffee leaf rust (Hemileia vastatrix) and to promote the growth of coffee seedlings. None ...
Dietary restriction, caloric value and the accumulation of hepatic fat
(Lipids in Health and Disease, 2012-01-05) [Artigo]
Background: Studies using laboratory animals under what are considered to be standard conditions normally offer unrestricted amounts of food to the animals, which can lead to metabolic disorders. Moreover, standard diets ...
Optimisation of a continuous flash fermentation for butanol production using the response surface methodology
(Chemical Engineering Research & Design, 2010-05-01) [Artigo]
Factorial design and response surface techniques were used in combination with mathematical modelling and computational simulation to optimise an innovative industrial bioprocess, the production of biobutanol employing the ...
Carbon dioxide formation during initial stages of photodegradation of poly(ethyleneterephthalate) (PET) films
(Materials Science and Technology, 2009-04-01) [Artigo]
Carbon dioxide (CO(2)) generation by ultraviolet irradiation of poly(ethyleneterephthalate) (PET) films in oxygen was monitored by in situ Fourier transform infrared spectroscopy. Typically, the CO(2) absorbance increased ...
