Refletir sobre a relação entre os festejos carnavalescos e o movimento folclorista implica admitir as diferenças de perspectivas na constituição desses campos. Observa-se, inicialmente, que os processos de institucionalização dos carnavais brincados no Rio de Janeiro entre os anos 1934 e 1937, configuram um campo cultural à parte do movimento folclorista que se efetiva no Brasil nas décadas seguintes. Enquanto as práticas carnavalescas se consolidaram na década de 1930, em mediação com a imprensa e com o poder público, ligadas às preocupações de forjar a nacionalidade, o movimento folclórico tenta se institucionalizar, com o mesmo propósito, e definir seu campo de atuação e objetos de pesquisas, entre as décadas de 40 e 60. Porém, o carnaval não é o cerne desse debate e tampouco manifestação que deva se integrar às tradições brasileiras.

The study of oscillatory phenomena is an important topic in several areas of knowledge. The understanding and the solution of many problems that scientists and engineers confront nowadays can be formulated, at least as an analogy, in terms of an oscillatory movement. The description of the motion of this nature has remarkable contributions to the mathematical and conceptual formation of the students and for solving daily problems in several areas. In this paper we propose a theoretical and experimental approach involving the phenomenon of harmonic oscillations in two dimensions. Lissajous curves were used as experimental demonstration of the resulting trajectories. These curves were obtained from relatively simple experimental apparatus, which is affordable in most teaching laboratories of physics.

The objective of this study was to obtain a mathematical equation to estimate the leaf area of Panicum maximum using linear measures of leaf blade. Correlation studies were conducted involving the real leaf area (Sf), the main vein leaf length (C), and the maximum leaf width (L). The linear and geometric equations related to C provided good leaf area estimates. For practical reasons, the use of an equation involving only the C*L product is suggested. Thus, an estimate of P. maximum leaf area can be obtained by the equation Sf = 0.6058 (C*L), with the coefficient of determination R = 0.8586.

The purpose of this study was to determine a shape factor to estimate area of leaflets of two peanut cultivars (IAC TATU ST, IAC RUNNER 886). Correlation studies were conducted involving real leaf area (Sf) and leaf length (C), maximum leaf width (L) and the product between C and L. For each cultivar was determined a form factor (f) by means of regression analysis between the product of the length by the width and the actual area of leaves and the correlation between leaf area estimated by the correction factor and direct measurement. All evaluated models (linear, exponential or geometric) provided good estimates of leaf area (above 87%). Linear models had the best fit, passing or not through the origin. From a practical viewpoint, it is suggested to use the linear model involving the C and L product, using a linear coefficient equal to zero, with values of factor f equal to 0.7111 and 0.7266 for IAC RUNNER 886 and IAC TATU ST, respectively. The method of dimensions is feasible for the estimation of leaf area for both peanut cultivars, for showing good r(2) values (0.97), with errors below 3%, even when used with independent data.

This research presents the results of a cephalometric radiography study, in frontal norm, that was used to measure the possible linear correlations between several linear dimensions of the face, in a sample of a 140 caucasian brazilians, with an average age of 20 years, who were distributed in 2 groups as follows: Control group - formed of 35 males and 35 females, with no apparent facial deformities and with dental oclusion, not necessarily, in Angle's Class I; Unilateral cleft lip and palate group - formed of 35 males and 35 females with surgical correction of the up in the first year and of the palate until the third year of life, without orthodontic treatment. ln each teleradiography, the following parameters were measured using a computer: - Lateral orbit width or external orbit width (LOe) - Medial orbit width or internal orbit width (LOI) - Zygomatic width or facial width (LZI) - Mastold width (LMa) - Maxilar width (LMx) - Nasal width (LNa) - Condilar width (LCo) - Antigonial width (LGa) The values obtained were treated statistically using quantitative analysis (arithmetic mean, standard deviation, standard mean error, Person's variation factor and Pearson factor linear correlation). Theirs significance was established by Student's t test. The Pearson factor linear correlations determined between transverse linear cephalometric width dimensions of face in frontal norm for individuals of both groups and sex, with an average age of 20 years, were: ...

It is imortant to be able to evaluate the cardiact size . In 1995, was proposed by Buchanan and Bücheler a new way to measure the dimensions of the cardiac silhouette. This study aims to gather several studies of the cardiac dimensions by VHS method in the right lateral recumbency of of different breeds of dogs in a single work, facilitating the assess to information. Deep chest breeds have a smaller mean VHS value than the barrel chest breeds, showing that there is a variation of the VHS values acoording to the thoracic conformation of each breed, which indicates that there is a need to recognize the specific VHS values according to the breed standard to not to interpret the cardiac measurement in a wrong way through not compatible reference values for the animal. There is the individual variation that should be taken into accont at the time of measurement. The VHS is a helper method to a radiographic evaluation of the heart, and the ultrasonography remains the gold standard for the evaluation of the cardiac chambers and other changes of the heart

Dentre as várias instituições das quais o ser humano participa, a escola é uma das mais importantes responsáveis pela construção da representação de quem somos. O educando é o objetivo maior da escola, mas na especificidade da Educação Física que, em geral, é totalmente desvinculada do projeto educacional das escolas, muito pouco tem sido feito, na prática, no sentido de educar os alunos “para a vida. Assim, esse trabalho tem como finalidade implementar aulas de Educação Física que contribuam para a formação do cidadão, e para isto foram elaboradas e desenvolvidas aulas que abordem o conteúdo handebol nas suas três dimensões: conceitual, procedimental e atitudinal. O método utilizado foi o da pesquisa-ação que, de natureza qualitativa, tem como característica o interrelacionamento entre o pesquisador e as pessoas participantes do estudo. As principais dificuldades foram: trabalhar novos conteúdos e a dimensão procedimental, e lidar com o número elevado de alunos. Porém, os momentos de tratar das dimensões conceituais e atitudinais foram muito bem sucedidos.

In this work we study extra dimensional theories, taking emphasis in braneworld models generated by real scalar fields. Firstly, we revise the Randall-Sundrum models and we discuss about some thick braneworld scenarios already considered in the literature. We introduce a new thick brane model in order to address the Standard Model hierarchy problem. Furthermore, we show that there exists a class of scalar fields models which are very interesting for analytical studies of thick brane scenarios. Finally, we analyze the braneworld consistency conditions in the context of f(R) and Brans-Dicke gravities, where we show that it is possible to evade a no-go theorem regarding thick brane scenarios
