The study's objective was to realize comparisons among different acepromazine, chlorpromazine and methotrimeprazine doses, evaluate parametric changes, test analgesia using press and term algimetry, and evaluate bispectral condition. 90 mongrel dogs were used, male and female, adult, weighting 10 to 15 Kg as a rule, distributed in 9 groups with 10 animals each. At first, second and third groups acepromazine was used at 0,1; 0,05 e 0,025 mg/Kg, respectively. At forth, fifth and sixth groups, chlorpromazine was used at 1,0; 0,5 and 0,25 mg/Kg, respectively. At seventh, eighth and ninth groups, methotrimeprazine at 1,0; 0,5 and 0,25 mg/Kg was used, respectively. All drugs were administered intravenously. objects of study: heart rate (HR), non invasive blood pressure (SAP, MAP, DAP), respiratory rate (f), capnography (ETCO(2)), pulse oxymetry (SatO(2)), mouth and rectal temperature, bispectral index (BIS), electromyography (EMG%), press and term algimetry. Somatic analgesia was evaluated by animal's response to nociceptives stimulus. We concluded that chlorpromazine had more bypotension. Dogs showed higher hypnosis level at: chlorpromazine group, with evident myorelaxation. All groups showed analgesia to thermic and mechanic stimulus. Acepromazine group showed high duration to both pain stimuli. Bispectral index was shorten at chlorpromazine group at 1,0 mg/kg doses, showing higher hypnosis index, and acepromazine was the less depressing considering the bispectral index.

This article analyzes the degree of thermopluviometric influence on certain indicators in the commerce of Maringa, state of Parana. To the end, climate elements, such as the temperature and prectipitation as well as certain economic indicators, namely: ICMS (taxes), SCPC, Video-Check, Consumption and Consumers of Electric Energy were studied. Graphical analyses along with statistical applications of correlation and regression were performed, as well as the examination of a case study. It is believed that the groups investigated showed variations in the forms of correlation. The results herein presented are in the manner of preliminary trial, representing a first attempt at measuring the actual relationship between the climatic variables (temperature and precipitation) with certain behavioural indicators of commerce in the city of Maringa.

Birth weight and placental weight of 566 newborns were determined. The newborns were classified by birth weight and gestational age in seven groups: term, preterm and postterm newborns with weight appropriate for gestational age; term and postterm newborns small for gestational age; term and preterm newborns large for gestational age. The differences in the mean placental weight in the preterm, term and postterm newborns with weight appropriate for gestational age were not significant. After 34 weeks of gestation there was little increase in placental weight. The mean placental weight of newborns large for gestational age was significantly different from that of term newborns appropriate for gestational age. In the term and postterm newborns small for gestational age the mean placental weight was significantly different from term and postterm newborns appropriate for gestational age. These findings suggest that newborns with an appropriate intrauterine growth have little increase in placental weight in the gestational period. Gestational age is not an important factor in determining placental weight in this period. Nutrition is important for placental growth-retarded infants have small placentas and large-for-date infants have large placental weight.

In this work, a Finite Element Method treatment is outlined for the equations of Magnetoaerodynamics. In order to provide a good basis for numerical treatment of Magneto-aerodynamics, a full version of the complete equations is presented and FEM contribution matrices are deduced, as well as further terms of stabilization for the compressible flow case.

BACKGROUND: One of the great difficulties in evaluating a voice is the judgment of quality through the perceptual auditive analysis--although frequently used--, as it is influenced by socioeconomic and cultural aspects as well as individual preferences. Many are the adjectives and methods used in this assessment, especially because of the subjectivity involved in the process, leading to incompatibilities between listeners and difficulties in reaching a consensus on the use of this or that terminology. In such a context, the voice laboratory and more specifically the acoustic computerized analysis, has guided and complemented speech-language treatments. Among the several possibilities of spectrographic analysis, the (Long-Term Average Spectrum--LTAS) quantifies the quality of voices, pointing differences between gender, age, professional--spoken and sang--and dysphonic voices. The LTAS has been used a lot in researches that investigate voice. As it evidences the contribution of the glottic source and of resonance to the quality of voice, it provides objective parameters for the evaluation of this aspect which usually depends on our auditive perception. AIM: to demonstrate how LTAS can be applied in voice research and in the speech-language therapy practice, describing both the technical aspects required for the production and interpretation of results, and its limitations. CONCLUSION: The area of voice research has developed a lot in these last two decades especially because of the advent of the voice and speech laboratory. For this reason, the knowledge about the applicability of more tools for voice analysis, as the LTAS, as well as the existing need for more studies in this area, will most certainly contribute for the creation of new research areas not only in the field of professional voice but also in the field of therapy.

Objectives: To describe the use of antenatal corticosteroid and clinical evolution of preterm babies. Methods: An observational prospective cohort study was carried out. All 463 pregnant women and their 514 newborn babies with gestational age ranging from 23 to 34 weeks, born at the Brazilian Neonatal Research Network units, were evaluated from August 1 to December 31, 2001. The data were obtained through maternal interview, analysis of medical records, and follow-up of the newborn infants. Data analysis was performed with the use of chi-square, t Student, Mann-Whitney, and ANOVA tests and multiple logistic regression, with level of significance set at 5%. Results: Treatment was directly associated with the number of prenatal visits, with maternal hypertension and with the antenatal use of tocolytic agents. Babies from treated pregnant women presented better Apgar scores at the 1st and 5th minute, reduced need for intervention in the delivery room and lower SNAPPE II. They were born with higher birth weight, longer gestational age and needed less surfactant use, ventilation, and oxygenation time. After multiple logistic regression, the use of antenatal corticosteroid independently improved birth conditions, decreased ventilation time, being related to increased occurrence of neonatal sepsis. Conclusions: The use of corticosteroid was associated with better prenatal care and birth conditions, better preterm evolution but higher risk of infection. © 2007 Sociedad Chilena de Pediatría.

The applications of the Finite Element Method (FEM) for three-dimensional domains are already well documented in the framework of Computational Electromagnetics. However, despite the power and reliability of this technique for solving partial differential equations, there are only a few examples of open source codes available and dedicated to the solid modeling and automatic constrained tetrahedralization, which are the most time consuming steps in a typical three-dimensional FEM simulation. Besides, these open source codes are usually developed separately by distinct software teams, and even under conflicting specifications. In this paper, we describe an experiment of open source code integration for solid modeling and automatic mesh generation. The integration strategy and techniques are discussed, and examples and performance results are given, specially for complicated and irregular volumes which are not simply connected. © 2011 IEEE.
