The objectives were to evaluate the effects of synchronizing estrus and ovulation to implement a timed artificial insemination (AI) at first insemination on reproductive performance and cost per pregnancy in dairy heifers. Six hundred eleven Holsteins heifers at approximately 400 d of age from 3 farms were enrolled in the study. Six days before moving to(More)
A espectrometria de absorção atômica em forno de grafite de alta resolução com fonte contínua (HR-CS GF AAS) é proposta para determinar Pb em sombra de olho e blush empregando a análise direta de sólidos. O emprego da mistura de modificadores químicos Pd(NO3)2 + Mg(NO3)2 possibilitou a calibração aquosa de 0,25 a 2,5 ng Pb (r = 0,998). O desempenho do(More)
-This work presents an accurate and precise Genetic Algorithm (GA) for frequency estimation of Electrical Power System (EPS) signals. The problem of estimating the frequency of a distorted electrical signal is modeled as an optimization problem. The advantages of GAs in this approach include the use of coding for a number of solutions which facilitates(More)
