Low genetic diversities of rabies virus populations within different hosts in Brazil
(Elsevier B.V., 2010-03-01)
The low rates of nonsynonymous evolution observed in natural rabies virus (RABV) isolates are suggested to have arisen in association with the structural and functional constraints operating on the virus protein and the ...
Fast fault section estimation in distribution control centers using adaptive genetic algorithm
(Elsevier B.V., 2014-12-01)
This paper presents a novel mathematical model for fast fault section estimation in a Distribution Control Center (DCC). The mathematical model is divided into two parts, namely: (1) a protection system operations model ...
Mechanistic contributions of residues in the M1 transmembrane domain of the nicotinic receptor to channel gating
(Taylor & Francis Ltd, 2004-01)
The nicotinic receptor (AChR) is a pentamer of homologous subunits with an α2βεδ composition in adult muscle. Each subunit contains four transmembrane domains (M1-M4). Position 15′ of the M1 domain is phenylalanine in α ...
Kinetic studies of rat liver hexokinase D ('glucokinase') in non-co-operative conditions show an ordered mechanism with MgADP as the last product to be released
(2003)
The kinetic mechanism of rat liver hexokinase D (‘ glucokinase’)
was studied under non-co-operative conditions with 2-
deoxyglucose as substrate, chosen to avoid uncertainties derived
from the co-operativity observed ...
Early diagnosis of multiple endocrine neoplasia type 2B: a challenge for physicians
(Sociedade Brasileira de Endocrinologia e Metabologia, 2008-11-01)
BACKGROUND: The hereditary form of medullary thyroid carcinoma may occur isolated as a familial medullary thyroid carcinoma (FMTC) or as part of Multiple Endocrine Neoplasia 2A (MEN2A) and 2B (MEN2B). MEN2B is a rare ...
Novo algoritimo genético para problemas de cobertura de conjuntos
(2011)
The Set Covering Problem (SCP) plays an important role in Operational Research since it can be found as part of several real-world problems. In this work we report the use of a genetic algorithm to solve SCP. The algorithm ...
Evaluation of Operating Room Environment Contamination and Efficacy of 2% Chlorhexidine for Surgical Hand Scrubbing before and after Gowning and Gloving
(Univ Fed Rio Grande Do Sul, 2017-09-15)
Background: Human skin is colonized by various species of microorganisms, which makes them difficult to eliminate even with the use of antimicrobial drugs. Real efficacy of the antimicrobial product combined with incorrect ...
An efficient Particle Swarm Optimization approach to cluster short texts
(Elsevier, 2014-05)
Short texts such as evaluations of commercial products, news, FAQ’s and scientific abstracts are important resources on the Web due to the constant requirements of people to use this on line information in real life. In ...
A Chaotic Approach of Differential Evolution Optimization Applied to Loudspeaker Design Problem
(IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INCPISCATAWAY, 2012)
Over the past few years, the field of global optimization has been very active, producing different kinds of deterministic and stochastic algorithms for optimization in the continuous domain. These days, the use of ...
