Educação Física no Ensino de 1° e 2° Graus: Para que Serve?

O ser humano possui uma natural necessidade de movimento e atividade física, desde o nascimento até a idade avançada (Cumming, 1977). Na sociedade atual, o fenômeno da automação, fruto do desenvolvimento tecnológico e econômico, leva os indivíduos ao sedentarismo, dificultando o desenvolvimento normal de suas potencialidades físicas e emocionais.

Trabalho e cidadania: em direção a uma vinculação enriquecida

A armadilha posta pelo capitalismo para seus críticos, de defender o emprego da força de trabalho pelo capital como um direito, assume atualmente importante especificidade: o retorno histórico da substituição dos homens por máquinas, mediante a automação de base eletrônica, significa a superação do taylorismo-fordismo. Essa forma de produzir significou uma mediocrização do capitalismo quanto ao desenvolvimento das forças produtivas, dado que lastreava a produção no trabalho vivo. Por ter gerado um círculo virtuoso capital/trabalho, com fortalecimento dos sindicatos e elevação de salários, o fim histórico do taylorismo-fordismo é lamentado por muitos. Na verdade, o capitalismo voltou a ser brilhante quanto ao desenvolvimento das forças produtivas, o que tenderá a marcar de forma cada vez mais nítida sua mediocridade como forma social. Será então possível (e necessário) superar a vinculação empobrecida entre trabalho e cidadania, típica do fordismo, em direção a uma vinculação enriquecida entre os dois conceitos.

Desenvolvimento de experiências de acionamento e controle do movimento angular de motores de indução trifásico

This paper aims to show practical and effectiveexperiencesfor lessons Industrial Automation Laboratory taught inundergraduate degreein ElectricalEngineering from the University Júlio MesquitaFilho - UNESP, Guaratinguetá. Experiments carriedsimulatecontrol and drive systems of electric three phase induction motors (MIT)widely usedinindustries. The experiments simulate a manufacturing environment where there isa need to control the activation and continuous operation ofelectricmotors. Seven experimentsthat simulatethe firing of electrical motors through a controlsystem, a driver along with asimulator loads coupled to the electric motor was developed. Experiments usinga Programmable Logic Controller (PLC) as acontroller,an inverter frequencyasdriver, and MagneticBrake, as simulatorengine loads . The experiments were divided accordingto the speed reference signal used fordrivingand operating the electric motor: digital and analog. The first five experiments performing the drive control and operation of the electric motor via digital signals. The sixth and seventh experiments using an analog signal as a reference speed for the electric motor

Influência de software de otimização de corte no rendimento de serraria da região sudoeste paulista

This study aimed to analyze the increase of yield provided by a software optimization cutting in a pine sawmill, located at southwest region of São Paulo, city of Itapeva. First were measured 10 logs that were processed by conventional sawing system by measuring the volume of products in the process output. Then using a cutting optimization software, that generated cuts diagrams, 10 logs, from 25 to 26 cm diametrical class, were processed by sawing system optimized. For the conventional sawing, the value found to yield was 41.80%, whereas for the unfolding optimized showed the value of 61.79%, resulting in a difference of 19.99%. This study shows that there is room for significant improvement of performance in sawmills sawing with the use of optimization software as the employee at work

Desenvolvimento da técnica de MALDI Imaging utilizando tecidos animais

Currently the study of important molecular compounds present in low abundance in some tissues has been a challenge for proteomic analysis classic. An analysis requires more exploratory investigation of small regions of a tissue or a group of cells. MALDI Imaging Technology (MSI) is an application of mass spectrometry facing the chemical analysis of intact tissues. Thus, advances in mass spectrometry MALDI being obtained by the integration of histology, the best methods and automation are the main tools of data analysis. This tool has become essential to analyze the spatial distribution of peptides and proteins throughout the tissue sections, providing an enormous amount of data with minimum sample preparation. Thus, the aim of this study was to develop the technique of MALDI Imaging using tissue from glioblastoma multiforme (GBM), a form of most common malignant tumor in the brain. For this we used the printer chemical ChIP-1000 (Chemical Inkjet Printer, Shimadzu) and mass spectrometer type Maldi-ToF-ToF (Axima Performance, Shimadzu), a search of the identifications were performed in databases such as SwissProt. We identified more than forty proteins with diverse functions such as proteins F-actin-capping and Thymosin to the structure and organization cellular and proteins such several Tumor necrosis factor receptor development-related pathology. The development of this technique will permit to carry-out proteomic analysis directly into the tissue, enabling earlier diagnosis of diseases, as well as the identification and characterization of potential biomarkers of disease.

Avaliação experimental de medidas de aceleração

Acceleration is a key parameter for engineering and is becoming increasingly important because of the need for companies to become more competitive in the market. Both applying new technologies to their products and optimizing their process lines with predictive maintenance and robotic automation. This study aims to analyze the quality of the signals obtained from a capacitive accelerometer. To do that a test rig was mounted, which consist of a shaker, fed by a signal generator, a linear potentiometer and a capacitive accelerometer; for the signal acquisition was used a acquisition board and the Labview software, in order to integrate twice the signal from the accelerometer and compare it with the sign of the potentiometer. This work also demonstrates the impact of acquired signal processing as well as techniques of pre and post processing of signal via software GNU/Octave

O efeito da autocorrelação no desempenho dos gráficos de X e R e dos gráficos de X e S²

Control charts are very important tools in statistical quality control of industrial processes and its use started last century. Since its development, the charts have always been attributed to independent processes, i.e. without any correlation between samples. But nowadays, with the high level of automation in the industrial environment, it is noticeable the autocorrelation factor between samples. The main Xcharts used in monitoring quality characteristics represented by continuous variables are the mean (X ), amplitude (R) and variance (S²). Therefore, this work aims to analyze the performance of X and R charts and in of X and S² charts with different sample sizes (4 and 5) for monitoring autocorrelated processes. Through computer simulations using the Fortran software and the use of mathematical expressions was possible to obtain data and performance analysis of the detection power charts for independent observations and for autocorrelated observations according to the model AR (1). The results show that the effect of autocorrelation reduces the ability of monitoring the control charts and that, the greater this effect, the slower the chart becomes in misfits signaling
