Genetic heterogeneity of Escherichia coli strains isolated from raw milk, Minas...

From February 2004 to March 2005, 140 samples of food handlers - hands and nostrils - (92), raw milk (24), and minas frescal cheese (24) were analyzed for the presence of Escherichia coli in a dairy processing plant of Goiás State. Forty-seven E. coli strains were obtained and compared by DNA macrorestriction patterns obtained from pulsed-field gel electrophoresis following XbaI restriction in order to investig...

Is threshold useful in accelerating weaning from mechanical ventilation?

Parâmetros genéticos entre características de leite, de peso e a idade ao prime...

Foram estimadas as correlações genéticas entre características de produção de leite (produção de leite, gordura, proteína e duração da lactação em até 305 dias, na primeira lactação), características de peso (taxa de crescimento de novilhas entre 12-24 meses e peso médio de vacas) e idade ao primeiro parto, em uma população de fêmeas Mestiço Leiteiro Brasileiro (MLB), por meio de metodologia REML, sob modelo an...

Predictive QSPR analysis of corrosion inhibitors for super 13% Cr steel in hydr...

An experimental and theoretical study on the inhibition corrosion efficiencies of twenty three compounds in hydrochloric acid (15% w/v) on 13% Cr modified stainless steel (martensitic) has been carried out. This inhibitor set includes amines, thiourea derivatives and acetylenic alcohols. Experimental weight losses at 60ºC were correlated with group and quantum AM1 descriptors obtained from QSPR analysis. Such d...

MECP2 coding sequence and 3'UTR variation in 172 unrelated autistic patients

Mutations in the coding sequence of the methyl-CpG-binding protein 2 gene (MECP2), which cause Rett syndrome (RTT), have been found in male and female autistic subjects without, however, a causal relation having unequivocally been established. In this study, the MECP2 gene was scanned in a Portuguese autistic population, hypothesizing that the phenotypic spectrum of mutations extends beyond the traditional diag...

Influência da presença do bezerro no momento da ordenha sobre o desempenho repr...

Avaliou-se a influência da presença do bezerro no momento da ordenha sobre os parâmetros reprodutivos de 75 vacas primíparas e multíparas mestiças Holandês-Zebu, divididas em três grupos experimentais: GI - vacas ordenhadas sem a presença do bezerro; GII - vacas ordenhadas com a presença momentânea dos bezerros, sendo estes retirados da sala de ordenha logo após a descida do leite; e GIII - vacas ordenhadas com...

QSPR prediction analysis of corrosion inhibitors in hydrochloric acid on 22%-Cr...

Corrosion inhibitors have been widely used to prevent corrosion on stimulation operations on petroleum wells. Detailed experimental and theoretical investigation of twenty three different compounds including amines, thiourea derivatives, and acetylenic alcohols were carried out to estimate their inhibition corrosion efficiency on 22% Cr stainless steel (austenitic-ferritic, duplex) in hydrochloric acid (15% m/v...

Experimental behaviour of a steel structure under natural fire

Current design codes for fire resistance of structures are based on isolated member tests subjected to standard fire conditions. Such tests do not reflect the behaviour of a complete building under either normal temperature or fire conditions. Many aspects of behaviour occur due to the interaction between members and cannot be predicted or observed in tests of isolated elements. Performance of real structures s...
