Aplicação de um método híbrido de pontos interiores e branch-and-bound em problemas de minimização de custo de colheita da cana-de-açúcar
(Revista Eletrônica CQD, 2013) [Artigo]
Este trabalho tem o objetivo de desenvolver e aplicar um método híbrido que envolve os métodos previsor-corretor primal-dual de pontos interiores e branch-andbound em problemas referentes à minimização do custo de colheita ...
Nitric oxide reduces oxidative stress generated by lactofen in soybean plants
(Pesticide Biochemistry and Physiology, 2010-05-01) [Artigo]
Nitric oxide (NO) is a molecule able to directly scavenge ROS and end chain reactions, which can be generated by some herbicides This study aimed to evaluate whether the pretreatment of soybean plants with sodium nitroprusside ...
Inferring population connectivity across the range of distribution of the stiletto shrimp Artemesia longinaris Spence Bate, 1888 (Decapoda, Penaeidae) from DNA barcoding: implications for fishery management
(Zookeys, 2014-01-01) [Artigo]
Artemesia longinaris is a marine shrimp endemic to the southwestern Atlantic and distributed from Atafona, Rio de Janeiro (Brazil) to Rawson, Chubut (Argentina). In recent years, this species has become an important target ...
Schottky emission in nanoscopically crystallized Ce-doped SnO2 thin films deposited by sol-gel-dip-coating
(Thin Solid Films, 2008-11-28) [Artigo]
This paper reports the electrical effects of the incorporation of Ce(III) or Ce(IV) in SnO2 thin films, prepared by the sol-gel-dip-coating technique. This doping has drastically increased the resistivity compared to undoped ...
Biocompatibility studies of natural rubber latex from different tree clones and collection methods
(Journal of Materials Science: Materials in Medicine, 2014-02-01) [Artigo]
Natural rubber latex (NRL) has several features that make it an excellent biomaterial to promote the growth and repair of tissues, skin and bones. Most of the research with NRL membranes uses a mixture of different clones ...
Reproduction and recruitment of the seabob shrimp: a threatened exploitation species in southeastern of Brazil
(Boletim Do Instituto De Pesca, 2015-01-01) [Artigo]
This study evaluated the reproductive period and recruitment of the threatened exploitation shrimp Xiphopenaeus kroyeri (Heller) in the southeast coast of Brazil. Monthly samples were carried out from March 2008 to February ...
Isolation and characterization of microsatellite loci in the Neotropical fish Astyanax altiparanae (Teleostei: Characiformes) and cross-species amplification
(Journal of Genetics, 2012-04-01) [Artigo]
Common Descent of B Chromosomes in Two Species of the Fish Genus Prochilodus (Characiformes, Prochilodontidae)
(Cytogenetic and Genome Research, 2013-01-01) [Artigo]
To ascertain the origin of B chromosomes in 2 fish species of the genus Prochilodus, i.e. P. lineatus and P. nigricans, we microdissected them and generated B-specific DNA probes. These probes were used to perform chromosome ...
Forensic identification of the guitarfish species Rhinobatos horkelli, R-percellens and Zapteryx brevirostris using multiplex-PCR
(Molecular Ecology Resources, 2010-01-01) [Resumo]
Rhinobatos percellens, Rhinobatos horkelli and Zapteryx brevirostris, known as guitarfish, are commonly found inshore and caught by trawl nets. Recently, these species have been suffering sharp population declines. One of ...
Interface Formation and Electrical Transport in SnO2:Eu3+/GaAs Heterojunction Deposited by Sol-Gel Dip-Coating and Resistive Evaporation
(Journal of Electronic Materials, 2010-08-01) [Artigo]
The natural n-type conduction of tin dioxide (SnO2) may be compensated by trivalent rare-earth doping. In this work, SnO2 thin films doped with Eu3+ have been deposited by the sol-gel dip-coating (SGDC) process, topped by ...
