1. Partum and postpartum characteristics on the postpartum rebreeding in beef cattle
ABSTRACT The objective was to evaluate the influence of calving and postpartum characteristics, measured in different genetic predominance, on the postpartum rebreeding. Were evaluated 437 partum from cows that received feeding management consisting of a forage base of the native field and the mating season consisted of 90 days. The measurements were used fr

4. AU COMMENCEMENT ÉTAIT LA MÉTAPHORE: UNE INTUITION PRÉCOCE DE NIETZSCHE SUR LA PRIMAUTÉ DE LA MÉTAPHORE COMME MATRICE COGNITIVE
ABSTRACT This paper highlights the precedent, managed by the precocious insights of the young Nietzsche who advocated the structuring force of the metaphor as the matrix of cognitive powers. We first provide a short sketch of the postulates and gains of cognitive grammars. We examine the guidelines of the works on cognitive research led by great Eleanor Rosc

5. Uso de análise multivariada para determinar a associação do desempenho reprodutivo de machos suinos com as caracteristicas seminais / Use of multivariate analyses to determine the association of boar fertility with semen traits
The application of new approaches that measure certain sperm motion characteristics and their association with boar fertility has shown a recent increase. Computer-assisted semen analysis (CASA) offers standardized assessment of multiple sperm motion parameters and it is plausible that the combination of these parameters with morphological sperm defects may

6. Ensaios analíticos e numéricos de processos estocásticos unidimensionais / Analytic and numeric essays on one-dimensional stochastic processes
Nesta presente tese, abordaremos três problemas sobre processos estocásticos unidimensionais governados pela equação mestra. Através do Ansatz do Produto Matricial (MPA) determinaremos as condições suficientes para garantir a integrabilidade de um novo processo de difusão num meio com impurezas. Investigando o espectro de tal modelo, computaremos o e

7. DFA e análise de agrupamento aplicadas a perfis de porosidade neutrônico em poçosm de petróleo
Peng was the first to work with the Technical DFA (Detrended Fluctuation Analysis), a tool capable of detecting auto-long-range correlation in time series with non-stationary. In this study, the technique of DFA is used to obtain the Hurst exponent (H) profile of the electric neutron porosity of the 52 oil wells in Namorado Field, located in the Camp

8. Sistema de previsão imediata da precipitação: o hydrotrack / A rainfall nowcasting system: the hydrotrack
The knowledge of convective system evolution is of fundamental importance for understanding weather and climate, particularly in the tropics, and it is essential to improve forecasting of these systems to reduce vulnerability to extreme weather damage. The identification of predictor parameters of the evolution of convective system, based on its previous evo

9. SITA standard, SITA fast, tendency-oriented perimetry (TOP) e perimetria de frequencia dupla (FDT) em individuos submetidos a perimetria computadorizada pela primeira vez / SITA standard, SITA fast, tendency-oriented perimetry (TOP) and frequency-doubling technology perimetry in perimetrically inexperienced individuals
The aim of this study was to evaluate the sensitivity and specificity of the screening mode of Frequency-Doubling Technology (FDT), Tendency-Oriented Perimetry (TOP), SITA Standard (SS) and SITA Fast (SF) for the diagnosis of glaucoma in perimetrically inexperienced individuals. One eye of 64 glaucoma patients and 53 normal subjects who had never undergone a

10. The volume as a variable in the Cluster Variation Method. / Incorporação do volume ao método variacional de clusters.
The Cluster Variation Method (CVM), used in thermodynamical calculations, is based in the mean-field approximation to the free energy. The CVM was originally devised to treat configurational-only cases. The scope of the present work is to enhance the method s capabilities, introducing other free energy components. The volumetric contributions, either dilatac

11. Floristica e caracterização das comunidades vegetais da planice costeira de Picinguaba, Ubatuba-SP
In the present study, we examine a better floristic, base of the severa I communities better delimited that compose the vegetation complex of the coastal plain of Picinguaba. That plain possesses about 8 Krn2, situated in the township of Ubatuba, northern coast of the State of São Paulo, (23°20 -23°22 S /44°48 -44°52 W). This area is a Unit of Conservat

12. Motion detection threshold and field progression in normal tension glaucoma.
Psychophysical tests may demonstrate abnormalities of visual function before the appearance of conventional visual field loss in glaucoma. Motion detection thresholds (MDT) were measured in the normal fellow eye of 51 patients with confirmed normal tension glaucoma and initially unilateral field loss. Humphrey visual fields from the initially normal eye cove
