The aim of the study was to analyze the relationship between run-up spatial-temporal variables with ball velocity in the dominant and non-dominant kicks, and to compare the ball velocity between contralateral limbs. Six futsal players (aged 13 and 14 years) participated in the study. The participants performed 4 kicks with maximal velocity in the stationary ball with each limb. Participants’ movements were recorded by 4 digital cameras (120 Hz). Dvideow software was used for kinematic procedures. The variables analyzed were: length and width of the last but one step and last step before ball contact, distance of the support foot to the ball, run-up velocity and ball velocity. The relationship between spatial-temporal variables with the ball velocity was analyzed by linear regressions with ball velocity as dependent variable. Student t test for paired samples was used to compare ball velocity between dominant and non-dominant kicks. For the dominant limb, the ball velocity was predicted only by the run-up velocity in 16.7%, while for the non-dominant limb only the distance of the support foot to the ball was prognostic variable in 11.9%. The ball velocity was greater for the dominant limb. Run-up variables that predictive ball velocity were different between the dominant and non-dominant kicks.

The lesbian and gay movement has organized itself in Brazil with the goal of creating and making its sexual identity stronger, as well as fighting for its rights and against any homophobic act. This paper analyses the homosexual movement and its relation to building its own identity, as a fighting force. We emphasize the relevance of the manifestation events, such as the LGBT pride parade and, in Bauru, the diversity parade, events that not only provide visibility to the topic, with the presence of the media, but also, represent the voice of these people who search for their citizenship rights.

Birigui nasceu e se expandiu a partir da Estrada de Ferro do Noroeste do Brasil. Esta permitiu que o município não fosse somente um posto de parada, mas sim um núcleo urbano. Além disso, foi essencial para o traçado urbano, visto que as ruas e quadras foram feitas paralelas a linha férrea. No entanto, atualmente, o local que deu início a cidade, não mais possui vestígios históricos, visto que sua primeira estação ferroviária foi demolida para a construção de uma nova a 1,7 km de distância. Tal demolição ocorreu devido uma modificação necessária do traçado da linha férrea. Percebe-se, portanto, que parte do patrimônio ferroviário de Birigui foi demolido, e outra parte encontra-se inutilizada, constituindo um vazio urbano em meio a malha urbana. Dar atenção a esses elementos históricos e ao contexto atual em que Birigui se encontra são essenciais para a elaboração de um projeto de reabilitação de seu conjunto ferroviário. A proposta busca a elaboração de espaços públicos coerentes às necessidades da população do bairro e do município. Além disso, trata-se de reintegrar esse espaço ao desenho da malha urbana, de modo a não ser visto mais como uma cicatriz ou um espaço obscuro, mas sim como um espaço de convivência e permanência dos moradores, assim como de preservação histórica

The aim was to describe the positive and negative aspects in a family communication at an emergency care unit. This is a descriptive research with a qualitative approach. The sample consisted of 20 family members / caregivers of patients admitted to the emergency room of a university hospital. Data collection was carried out through semi-structured interviews applied during the period of May-June 2011. Data analysis was performed using the methodological framework of the Collective Subject Discourse which resulted in four themes: Lack of information compromising the family/health professional ties; The ideal model of information provided by the professional regarding the condition of the hospitalized relative; Assessment of information provided about hospital routines; and The role of the relative/companion. Therefore, for the patient and his family, communication is presented as a tool on the care given with the function of transmitting safety, respect and guidance. However when it is incomplete, it becomes a potential form of stress and dissatisfaction.

Hyperkalemia is a common electrolyte imbalance in cats with obstructive feline lower urinary tract disease (FLUTD). The effects of serum potassium elevation in heart rhythm are serious and potentially lethal. The clinical manifestations reflect changes in the excitability of the cell membrane. Increased potassium levels lead to a reduction of the resting membrane potential of heart muscle cells, making them less excitable and resulting in cardiac arrhythmias. The sinoventricular rhythm with atrial arrest is among the types of arrhythmias caused by hyperkalemia. The purpose of this report was to highlight the importance of electrocardiographic monitoring for the early detection of potentially lethal arrhythmias in cats with obstructive FLUTD. We hereby describe the occurrence of three cases treated at the Small Animal Clinic of FMVZ/Unesp, Botucatu Campus.

This paper purpose is to analyze one of the main problems faced by cold rolling industry of the current time, the mechanical vibration. Factors such as strips with high velocity in order to increase the productivity and thickness becoming thinner and thinner cause the vibrations to be present at all times during rolling. These market requirements also drive the industry for technology development and thus bring the challenges that the operation of a new modern equipment and more powerful. The initial purpose is to analyze the forces that cause vibration in a rolling mill type four high with two stands, where is desirable to identify the origins of these vibrational forces to make possible dismiss them or at least control its intensity, in order to prevent damage in the rolling mill and ensure product quality to the customer. For it, will be used instruments to record and store the vibrations that occur during the lamination process. With this data will be able to analyze the characteristics of the vibrations and act at your elimination. At the end of the work is expected to demonstrate how important the critical view of the engineer in the analysis of graphics combined with the calculations of the natural vibration frequency and engagement of key parts of the laminator. With these two tools at hand, will be possible to increase the productivity of the rolling mill and act preventively in maintenance, thereby reducing your downtime and increasing its performance and efficiency

Aboveground tropical tree biomass and carbon storage estimates commonly ignore tree height (H). We estimate the effect of incorporating H on tropics-wide forest biomass estimates in 327 plots across four continents using 42 656 H and diameter measurements and harvested trees from 20 sites to answer the following questions: 1. What is the best H-model form and geographic unit to include in biomass models to minimise site-level uncertainty in estimates of destructive biomass? 2. To what extent does including H estimates derived in (1) reduce uncertainty in biomass estimates across all 327 plots? 3. What effect does accounting for H have on plot- and continental-scale forest biomass estimates? The mean relative error in biomass estimates of destructively harvested trees when including H (mean 0.06), was half that when excluding H (mean 0.13). Power- and Weibull-H models provided the greatest reduction in uncertainty, with regional Weibull-H models preferred because they reduce uncertainty in smaller-diameter classes (< 40 cm D) that store about one-third of biomass per hectare in most forests. Propagating the relationships from destructively harvested tree biomass to each of the 327 plots from across the tropics shows that including H reduces errors from 41.8 Mg ha(-1) (range 6.6 to 112.4) to 8.0 Mg ha(-1) (-2.5 to 23.0).

Ascending nociceptive control is a novel spino-striato-rostral ventral medulla pain modulation pathway that mediates heterosegmental pain-induced analgesia, i.e., noxious stimulus-induced antinociception. In this study, we used the dorsal immobility response in rats as a model of the defensive responses. We demonstrated that the activation of ascending nociceptive control by peripheral noxious stimulation and spinal AMPA and mGluR1 receptor blockade significantly potentiated the duration of the dorsal immobility response in rats via an opioid-dependent mechanism in the nucleus accumbens. These results demonstrated the functional role of ascending nociceptive control in the modulation of defensive responses and spinal glutamatergic receptors in the dorsal immobility response. The immobility response is an antipredator behavior that reflects the underlying state of fear, and ascending nociceptive control may modulate fear. (c) 2012 Elsevier B.V. All rights reserved.

Neurosonological studies, specifically transcranial Doppler (TCD) and transcranial color-coded duplex (TCCD), have high level of specificity and sensitivity and they are used as complementary tests for the diagnosis of brain death (BD). A group of experts, from the Neurosonology Department of the Brazilian Academy of Neurology, created a task force to determine the criteria for the following aspects of diagnosing BD in Brazil: the reliability of TCD methodology; the reliability of TCCD methodology; neurosonology training and skills; the diagnosis of encephalic circulatory arrest; and exam documentation for BD. The results of this meeting are presented in the current paper.

The ability of nanoassisted laser desorption-ionization mass spectrometry (NALDI-MS) imaging to provide selective chemical monitoring with proper spatial distribution of lipid profiles from tumor tissues after plate imprinting has been tested. NALDI-MS imaging identified and mapped several potential lipid biomarkers in a murine model of melanoma tumor (inoculation of B16/F10 cells). It also confirmed that the in vivo treatment of tumor bearing mice with synthetic supplement containing phosphoethanolamine (PHO-S) promoted an accentuated decrease in relative abundance of the tumor biomarkers. NALDI-MS imaging is a matrix-free LDI protocol based on the selective imprinting of lipids in the NALDI plate followed by the removal of the tissue. It therefore provides good quality and selective chemical images with preservation of spatial distribution and less interference from tissue material. The test case described herein illustrates the potential of chemically selective NALDI-MS imaging for biomarker discovery.

OBJECTIVES: The present investigation aimed to study the protective effect of intermittent normothermic cardioplegia in rabbit's hypertrophic hearts. METHODS: The parameters chosen were 1) the ratio heart weight / body weight, 2) the myocardial glycogen levels, 3) ultrastructural changes of light and electron microscopy, and 4) mitochondrial respiration. RESULTS: 1) The experimental model, coarctation of the aorta induced left ventricular hypertrophy; 2) the temporal evolution of the glycogen levels in hypertrophic myocardium demonstrates that there is a significant decrease; 3) It was observed a time-dependent trend of higher oxygen consumption values in the hypertrophic group; 4) there was a significant time-dependent decrease in the respiratory coefficient rate in the hypertrophic group; 5) the stoichiometries values of the ADP: O2 revealed the downward trend of the values of the hypertrophic group; 6) It was possible to observe damaged mitochondria from hypertrophic myocardium emphasizing the large heterogeneity of data. CONCLUSION: The acquisition of biochemical data, especially the increase in speed of glycogen breakdown, when anatomical changes are not detected, represents an important result even when considering all the difficulties inherent in the process of translating experimental results into clinical practice. With regard to the adopted methods, it is clear that morphometric methods are less specific. Otherwise, the biochemical data allow detecting alterations of glycogen concentrations and mitochondria respiration before the morphometric alterations should be detected

Este trabalho visou a avaliar a concepção de responsabilidade social de gestores e empregados de algumas empresas que participam da Política Nacional de Integração da Pessoa com Deficiência. A amostra foi constituída por 57 sujeitos, divididos em dois grupos: gestores e empregados. O grupo de gestores foi formado por 19 profissionais de recursos humanos, e o grupo de empregados, por 38 profissionais com deficiência. Os sujeitos foram solicitados a escrever as associações evocadas pelas palavras responsabilidade social em um período de 90 segundos. A partir dos dados coletados, as respostas dos sujeitos foram agrupadas em oito categorias: preocupação com o ambiente, inclusão social, solidariedade, respeito, compromisso social, sentimentos e atitudes positivos, coletividade e outras respostas. A análise estatística do Qui-quadrado permitiu rejeitar a hipótese nula com um alto grau de probabilidade. Verificou-se que o maior número de respostas associadas ao conceito de responsabilidade social concentrou-se nas categorias inclusão social, sentimentos/atitudes positivos e preocupação com o meio ambiente que, em conjunto, englobaram pouco mais da metade (52%) do total das respostas. A fim de avaliar o grau de associação entre as respostas dos gestores e dos empregados, foi calculado o coeficiente de correlação posto-ordem de Spearman. Os resultados permitiram identificar uma rede de conceitos associados ao conceito de responsabilidade social, tal como previsto por uma das teorias sobre formação de conceitos: a visão teórica.
