APPLICATION OF BIOMECHANICAL CONCEPTS IN PROFESSIONAL LIFE OF PHYSICAL EDUCATION TEACHER

The aim of this study was to determine which biomechanical concepts the physical education teachers apply in their professional life and whether there are differences between those who work in training field or at school. For this purpose a questionnaire was answered by 32 teachers. It was found that in the two areas more than half of the subjects said that apply the concepts, respectively 81% and 69%. The used concepts in training was levers (n=9) and motion analysis (n=8) and at school analysis of movement (n=8). The Physical Education professionals do not recognize the substance content of biomechanics, because movement analysis is an elementary part of biomechanics qualitatively and quantitatively. We conclude that Biomechanics’ teachers in the University should readjust the content of the discipline to fit the needs of the professional

Análise preliminar de caracterlsticas fisico-quimicas de frutos em hibridos (Tommy Atkins x Haden) de mangueira.

O trabalho objetivou estimar a associação de três características físico-químicas de fruto [o peso (PF), a largura (LF) e o comprimento (CF)) de uma população segregante, resultante do cruzamento entre as variedades Tommy Atkins e Haden, mantida na Estação Experimental de Mandacaru, localizada na Embrapa Semi-Árido

Comparison of efficiency of distance measurement methodologies in mango (Mangifera indica) progenies based on physicochemical descriptors.

We investigated seven distance measures in a set of observations of physicochemical variables of mango (Mangifera indica) submitted to multivariate analyses (distance, projection and grouping). To estimate the distance measurements, five mango progeny (total of 25 genotypes) were analyzed, using six fruit hysicochemical descriptors (fruit weight, equatorial diameter, longitudinal diameter, total soluble solids in °Brix, total titratable acidity, and pH). The distance measurements were compared by the Spearman correlation test, projection in two-dimensional space and grouping efficiency. The Spearman correlation coefficients between the seven distance measurements were, except for the Mahalanobis’ generalized distance (0.41 ? rs ? 0.63), high and significant (rs ? 0.91; P < 0.001). Regardless of the origin of the distance matrix, the unweighted pair group method with arithmetic mean grouping method proved to be the most adequate. The various distance measurements and grouping methods gave different values for distortion (-116.5 ? D ? 74.5), cophenetic correlation (0.26 ? rc ? 0.76) and stress (-1.9 ? S ? 58.9). Choice of distance measurement and analysis methods influence the characterization of genetic variability, and this should be taken into account for studies of mango

On the Electromagnetic Response of Charged Bosons Coupled to a Chern-Simons Gauge Field: A Path Integral Approach

We analyze the electromagnetic response of a system of charged bosons coupled to a Chern-Simons gauge field. Path integral techniques are used to obtain an effective action for the particle density of the system dressed with quantum fluctuations of the CS gauge field. From the action thus obtained we compute the U(1) current of the theory for an arbitrary electromagnetic external field. For the particular case of a homogeneous external magnetic field, we show that the quantization of the transverse conductivity is exact, even in the presence of an arbitrary impurity distribution. The relevance of edge states in this context is analyzed. The propagator of density fluctuations is computed, and an effective action for the matter density in the presence of a vortex excitation is suggested.Comment: LaTex file, 27 pages, no figure

Infestação domiciliar por Triatoma infestans e alguns aspectos epidemiológicos da tripanossomose americana em área do Estado de São Paulo, Brasil

Epidemiological investigations about American trypanosomiasis (Chagas' disease) in the area of Bairro da Ilha, County of Salto de Pirapora, S. Paulo State, Brazil, are reported. Twenty eight houses submited to the selective technique of insecticide spraying (BHC), was tested by Gómez-Núñez method. The results obtained showed that several houses still retains with infestations in a proportion not significatively different to the before the one noticed insecticide treatment. Only a reduction of the general infestation index was obtained. Beside this some evidence showed the possibility of the occurrence of natural foci of the infection. The rodents Akodon arviculoides and Oryzomys nigripes were found naturally infected by the use of xenodiagnosis technique. In the house environment, infections was found to persist, through the examination of new born or new introduced dogs and cats, little after the houses selective desinsetization. Two cats were found infected, one of them suggest to have adquired the infection by congenital way. The other positive animal, was introduced from another area. So we conclude by the necessity of a thorough revision of the prophylactic methods of Chagas' disease based only on the control of triatomids by insecticide use.São relatados os resultados das investigações sôbre epidemiologia da tripanossomose americana, levadas a efeito no Bairro da Ilha, município de Salto de Pirapora, Estado de São Paulo, Brasil. Em conjunto de 28 edifícios submetidos ao expurgo seletivo pela aplicação de BHC, procurou-se pesquisar a infestação por Triatoma infestans, através o método das caixas de Gómez-Núñez. O resultado revelou a persistência de edifícios infestados, em proporção semelhante àquela observada antes do expurgo. Contudo, houve redução da intensidade, revelada pela queda do índice geral de infestação. A pesquisa de focos naturais do parasito mostrou a possível existência da infecção em roedores Akodon arviculoides e Oryzomys nigripes. Levando-se a efeito xenodiagnósticos em cães e gatos, nascidos ou introduzidos logo depois do rociado seletivo, pôde-se evidenciar a persistência da transmissão, pelo menos por via congênita. Ao lado disso, observou-se a introdução precoce de animais infectados, procedentes de outras áreas. Conclui-se pela necessidade de revisão na profilaxia da doença de Chagas, baseada no simples combate aos triatomíneos pelo uso de inseticidas
