Efeito do modelo de periodização com cargas seletivas sobre capacidades motoras durante um mesociclo preparatório em jogadores de futsal

The aim of this study was to verify the effect of selective loads model in professional futsal players, during a preparatory mesocycle. Nine futsal professional players (23±2 anos), from the team of Federation Paulista of soccer indoor championship, composed the sample, characterized by intentional. The players were evaluated in two moments although of a preparatory mesocycle, microcycle 2 (PRE) and microcycle 7 (POS), by the tests of intermittent aerobic fitness, horizontal jump, one leg triple jump, velocity of 15m, agility and anaerobic power. The statistical analysis included the Student-t and Wilxocon tests (P<0.05). The results of horizontal jump, intermittent aerobic fitness and medium power improved, the velocity at 15 m decreased. The select loads model is a good option for the periodization to preparatory mesocycle in futsal.

Efeito das cargas de treinamento sobre parâmetros fisiológicos de futebolistas

The aim of this study was to investigate the effects of three weeks of training with intensity monitored on the aerobic capacity of professional soccer players. Fourteen players, members of a first division Brazilian Championship team in 2010, aged 22.78 +/- 3.06 years were evaluated pre and post three weeks of training. The anaerobic threshold intensity LAn was determined by bi-segmented method, for this four submaximal efforts of 800 meters with intensities 10, 12, 14 and 16 km/h were applied. Thirty three training sessions were quantified in zones according to heart rate related to the LAn (FCLAn): Z1 - 10% below, Z2 - 90-100% and Z3 - above the FCLAn. During training participants remained 31.17 +/- 14.86%, 42.96% and 25.87 +/- 14.90 +/- 16.67% in Z1, Z2, and Z3 respectively. There were no significant differences in the LAn (pre = 13,29 +/- 0,71 km.h(-1); post = 12,85 +/- 0,90 km.h(-1)), perceived exertion (pre = 11,53 +/- 1,45 u.a; post = 11,23 +/- 1,53 u.a) and FCLAn (pre = 166,64 +/- 10,69 bpm; post = 174,50 +/- 10,89 bpm) between conditions before and after training, indicating that three weeks of training are insufficient to generate positive changes in soccer players LAn.

Ampliação da capacidade da portaria de cargas de uma indústria através da implantação de um sistema de pesagem por eixo

Through a detailed study of each component, the structural part and various technologies for highway weighing scales, a project was developed in order to implement a modern system of axle weighing in a company pursuing to expand its cargo door capacity, which was restricted to weighing and inspection of the maximum load of each vehicle, and especially to extinguish the number of notifications that the company has been suffering, by having their transportation logistics vehicles caught traveling with poorly distributed load per axle, what it caused damage to roads and vehicles and denigrated the company image in terms of marketing. To achieve these results, the project went through a study of all relevant national legislation, seeking to put the company always in agreement. Moreover, it had investments and its physical space available for its implementation. The payback of such investments would be about less than three years

Influência da aplicação de cargas estáticas axias e não axais em próteses parciais fixas de três elementos, análise pela extensometria

Um bloco de poliuretano recebeu três implantes de hexagono externo, no posicionamento compensado. Para cada implante foi conectado o pilar protético microunit. Foram realizados cinco enceramentos com três coifas plásticas cada um, que foram fundidos em monobloco numa liga de cobalto-cromo. Foram colados quatro extensomêtros tangenciando cada implante, sendo dois extensomêtros para o implante central. Após o acabamento, as estruturas foram fixadas nos respectivos locais com o parafuso de retenção com torque de 10 Ncm, obtidos com um torquímetro. Para aplicação de carga sobre os corpos-de-prova foram selecionados cinco pontos de aplicação de carga. O dispositivo de aplicação de carga–DAC foi utilizado 30 kg de cargas verticais estáticas, empregando uma ponta esférica de 2 mm de diamêtro, durante 10 segundos em cada um dos pontos estabelecidos, sendo, neste instante registradas as micro deformações de cada extensômetro. Foi utilizado o teste de análise de variância T Student e o nível de significância foi o valor convencional de 5%. Para cada implante foi analisada a microdeformação ocorrida. Os resultados obtidos mostraram que houve uma diferença estatisticamente significativa entre os pontos não-axiais D e E (t = 5,21 df = 4, p = 0,006 < 0,05) e não foi estatisticamente significativa para os dados axial entre os pontos B e C (t = 6, 57, df = 4, p = 0,003 < 0,05 / 3). Conclui-se que,a aplicação de carga ao redor de três implantes de hexágono externo no posicionamento compensado,mostra que os pontos não-axiais sofrem maior micro deformação do que os pontos axiais

Melhorias dos processos no setor de expedição em uma transportadora de cargas fracionadas

The transport market has forced organizations reduce the cost of services and processes, resulting from the highly competitive and, for such waste at all levels and processes are a focus of study for its elimination. This study refers to carrier fractional loads, located in the municipality of Itapecerica da Serra Layout and headquartered in São Paulo, which requires a rapid development throughout its structure, because its expansion was not accompanied by an evolution of effective processes. The need to increase efficiency in delivery with a reduced cost of transport forced the company to hire a logistics consulting to help identify potential bottlenecks in processes, suggest improvements with greater impact and implementation at the end of a critical analysis of results. This work focuses on the Layout of the warehouse shipping area of this organization and we used the method of action research to the consultant and involved could reach this conclusion collaboratively, as well as interviews with those involved in the process and also visual observation. Tools such as Key Performance Indicator, Mapping Workflow, Analytic Hierarchy Process, Applied Statistics and Standard Operating Procedure were used to assist in the identification, analysis and implementation of the proposed improvements

Estudo de cargas térmicas de uma aeronave e dimensionamento de um sistema de ar condicionado

This work deals with the thermal load study of a fictitious aircraft as well as scaling, in terms of the airflow and temperature of the air conditioning system, for heating and cooling of the its internal environment, aiming the thermal comfort of occupants. The first part is presented the techniques and methods utilized for modeling different heat exchanges that occur in the aircraft and then allowed to calculate the total heat load and the airflow and temperature necessary to comply with the requirements of the thermal comfort. Techniques to determine the basic parameters, as convection coefficient and global coefficient of heat exchange, are also presented. The work aims to develop a program, using a computational tool, to automate the calculations so that facilitate this study. It also allows to be used for other airplanes just changing parameters and the control variables related to the specific project. Finally the program performs calculations for a fictitious airplane, to analyze its functionality and the influence of parameters involved in the temperature controls. The program allowed analyzing the sensitivity of portions of the thermal load and the corresponding parameters of influence, as well as the scaling of the air conditioning in terms of airflow and temperature. It was considered, despite the simplifications, a good approximation to the actual values and then can be used in development of the other airplanes

Geração de energia fotovoltaica para cargas pontuais em residências

This work, based in a patent request at INPI, protocol no. 020110035974, presents a system development using solar panels to supply the electricity demand required by punctual loads, without a storage unit or utility grid synchronism, through a control circuit that allows parallel operation with the power grid during low sunlight incidence periods. A study about solar panel construction and topologies for Power generation was done, in a atempt to evalute impacts in project. This development was modular, providing the system the possibility of power capacity expansion and load diversity as well, in an attempt to reduce the total energy requirements from the residential sector drained from the power grid along the day
