Potentiodynamic behaviour of CuA1Ag alloys in NaOH: a comparative study related to the pure metals electrochemistry
(Elsevier B.V., 1991-12-01)
The mechanism of electrochemical oxidation of surface reformed CuA1Ag alloys having different composition of heat treatment, in 0.5 M NaOH was studied by means of cyclic polarization, constant potential electrolysis, ICP, ...
Transcriptionally active LTR retrotransposons in Eucalyptus genus are differentially expressed and insertionally polymorphic
(BioMed Central, 2015-08-14)
In Eucalyptus genus, studies on genome composition and transposable elements (TEs) are particularly scarce. Nearly half of the recently released Eucalyptus grandis genome is composed by retrotransposons and this data ...
Effect of Twice-Daily Blue Light Treatment on Matrix-Rich Biofilm Development
(Public Library Science, 2015-07-31)
Background The use of blue light has been proposed as a direct means of affecting local bacterial infections, however the use of blue light without a photosensitizer to prevent the biofilm development has not yet been ...
Effect of time interval between bleaching and bonding on tag formation
(2005)
The objective of this study was to assess penetration of adhesive material in enamel bleached with 35% hydrogen peroxide using optical polarized light microscopy. Extracted human teeth were randomly assigned to 5 groups, ...
Historical knowledge, richness and relative representativeness of the avifauna of the largest native urban rainforest in the world
(Sociedade Brasileira de Zoologia, 2017)
ABSTRACT Stretching for more than 10,000 ha in the Metropolitan Area of São Paulo, southeastern Brazil, Serra da Cantareira comprises the largest native urban rainforest in the World, harboring a rich and diverse Atlantic ...
Variance partitioning of deconstructed periphyton communities: does the use of biological traits matter?
(Springer, 2014-01-01)
The use of species traits offers a promising approach to the understanding of the main processes underlying metacommunity patterns. We analyzed samples of periphytic algae in 30 environments of the Upper Parana River ...

(2015-01-01)
This paper described the architecture of the dog aortic arterial wall focused in the ascendant; thoracic descendent, and abdominal parts of the aorta. Furthermore, in this study we analyzed the wall structure of the right ...
Feeding ecology of the beach silverside Atherinella blackburni (Atherinopsidae) in a tropical sandy beach, Southeastern Brazil
(Inst Oceanografico, Univ Sao Paulo, 2017-07-01)
The feeding ecology of the beach silverside (Atherinella blackburni) in the surf zone of a tropical sand beach, located in the southeastern Brazil, was accessed through the gut content analysis of 198 fish. Factors such ...
Construction of 6 - thioguanine and 6 - mercaptopurine carriers based on beta cyclodextrins and gold nanoparticles
(Elsevier, 2017)
As a novel strategy to overcome some of the therapeutic disadvantages of 6-thioguanine (TG) and 6-mercaptopurine (MP), we propose the inclusion of these drugs in beta cyclodextrin (beta CD) to form the complexes beta CD-TG ...
Sediment quality in a metal-contaminated tropical bay assessed with a multiple lines of evidence approach
(Elsevier B.V., 2017-09-01)
A sediment quality assessment was performed near to the main industrial source of metal contamination in Sepetiba Bay, Brazil, which represents one of the worst cases of trace metal contamination reported for coastal areas. ...
