Hematology has a great importance in assessing the health of all animals, including reptiles, since it aids in the diagnosis of certain diseases and help to monitor patient's clinical evolution, although studies and articles in this area are rare, even with the increasing number of calls of these animals in veterinary clinics. Moreover, there are a lot of environmental and individual factors, which influence the hematological values of this group, such as age, sex, stress levels, nutrient levels and season which the exam was made, among others. For these reasons studies that aimed to evaluate the reference values of some specie, are essential to increase the knowledge in the field and to assist on the clinical approach. This paper aim’s to study the patterns of Hematology of Tortoise (Geochelone carbonaria) seeking the greater knowledge of clinical pathology of this species and increasing the possibilities for diagnosis, monitoring clinical outcome, and assessment of the general state and treatment

Introdução: A variabilidade da frequência cardíaca (VFC) descreve o comportamento dos intervalos RR que está relacionado às ações do sistema nervoso autônomo (SNA) sobre o nódulo sinusal. Essa pode ser influenciada por diversos fatores dentre eles a obesidade, doença de etiologia multifatorial definida como um acúmulo excessivo de gordura corporal. Objetivo: Avaliar em jovens obesos com idade entre 18 e 23 anos o comportamento autonômico cardíaco, durante o repouso, por meio da análise linear e não linear dos índices da VFC bem como associá-lo a eventos de desconforto músculoesquelético influenciados ou não pela prática regular de exercício físico nessa população. Metodologia: Para a realização deste estudo foram analisados dados de 68 voluntários jovens, de ambos os sexos, distribuídos de forma não randomizada em dois grupos: o G1 constituído por 32 obesos, 20,21 ± 1,66 anos e o G2 por 36 não obesos, 20,8 ± 1,47 anos sendo considerado como critério de classificação dos voluntários o índice de massa corpórea (IMC). O protocolo experimental consistiu da captação da frequência cardíaca batimento a batimento, por meio de uma cinta de captação fixada no tórax do voluntário juntamente com um receptor de frequência cardíaca fixado no punho. Para esta captação o voluntário foi orientado a permanecer em repouso na posição de decúbito dorsal sobre um colchonete, durante 30 minutos, com a respiração espontânea. Além disso, foram aplicados dois questionários, ou seja: versão curta do International Physical Activity Questionaire (IPAQ) - Questionário Internacional de Atividade Física, a fim de classificar o nível de atividade física e o Questionário Nórdico, para detectar eventuais sintomas osteomusculares decorrentes das atividades de vida diária e/ou atividades física. Os índices da VFC analisados foram: análise linear... (Resumo completo, clicar acesso eletrônico abaixo)

Introduction: The triangular index and the Poincaré plot (or Lorenz plot) are the best known indexes obtained from geometric methods. The triangular index (TINN, RRtri) represent the global variability of the subject and SD1, which reflects the parasympathetic component, SD2, index of global variability and its relationship (SD1/SD2) are obtained from the Poincaré plot. Despite the literature showing changes in the cardiovascular system during and after the resistance exercise (RE), aspects related to autonomic modulation of heart against these conditions have not been explored yet, so it is important to evaluate this behavior. Objectives: Analyze the acute effects of RE on the cardiac autonomic modulation during recovery (REC) through analysis of geometric indices of heart rate variability (HRV), applied with different intensities and muscle groups in healthy and active young. Methods: Were evaluated 24 young, 22.25 ± 2.4 years and 24.47 ± 3.08 kg/m2, underwent an experimental protocol of five stages, in the first stage was conducted a test of one maximum repetition (1RM) in upper limbs (UL) and lower limb (LL), and the following steps were initiated interventions to 40 (E) and 80% (F) of 1RM. Considered for HRV analysis the periods: baseline and immediately after exercise, both in supine... (Complete abstract click electronic access below)

The objective of this paper is to relate the set of financial ratios that are directly related to the success of public traded companies using a methodological approach and the method of multivariate principal component analysis. This study consists in the use of profitability ratios, debt and liquidity, to define the relationship between financial ratios with the best public traded companies listed in the magazine Exame Melhores e Maiores of 2013. Multivariate analysis was used to reduce the dimensionality of multivariate data, making linear combinations of the original variables (financial ratios) and express the data in principal components that result in new variables that contains much of the original data. As a result, we got the optimal number of five principal components, and both represent 95.6% of the original data. Among of all financial ratios, we can highlight the direct relationship between profitability ratios for the first principal component, and the direct relationship between the liquidity ratios, both inversely related with non-capital participation rates and degree indebtedness to the second principal component

With the advance of mathematical methods throughout the centuries, in particular with respect to the differential calculus, the notion of fractional derivative emerged with Leibniz and later developed by several well known scientists. Today that formalism is well used in the study of diffusion phenomena among other areas. We extend the fractional indices to matricial indices and develop a formalism to handle this generalized derivative, as well as other operators, functions and functionals in mathematical physics, originally defined for natural indices. Here we only consider 2x2 hermitian and anti-hermitian matrices. These matrices are associated to the well known Pauli matrices and Hamilton's quaternions. Applications with mathematical physics functions are presented
