Avaliação goniométrica da amplitude de movimento do ombro de crianças praticantes de beisebol

Introduction: Baseball is a Sport disputed by two teams composed at least by nine players which compete between themselves in a game of six innings in the amateur game, for children up to 10 years old. Objective: The objective is to compare the movement degrees of the shoulder joint between the dominant and the non dominant shoulder. Methods: Eleven male subjects were assessed (8,63 ± 0,67 years old) whom practiced baseball at the Nikkey Club of the city of Marília – SP. All of the subjects were assessed by the same examiner, whom measured the range of motion (ROM) of both glenohumeral joint. The Student t test was used for the comparison of the shoulders, with level of significance of 5% (p≤0,05). Results: The subjects presented significant differences on the external rotation movement (p= 0,014) between the dominant shoulder (63,63 ± 12,92°) and the non dominant shoulder (55,45 ± 16,27°), and in the internal rotation movement (p= 0,001) between the dominant shoulder (32,90 ± 5,68°) and the non dominant shoulder (40,72 ± 5,74°). Conclusion: The results obtained in this study, on the experimental conditions utilized, allow us to conclude that the practice of baseball influence the range of motion of external rotation and internal rotation of the dominant shoulder, with increased external rotation, and a decreased internal rotation, provoking instability of the shoulder joint.

Determinação de metais em água produzida de petróleo

In order to enable the reuse of the large surplus volume of petroleum produced water for irrigation of crops inedible, the quality evaluation of this water is very important. This work aimed to evaluate the effectiveness of the diffusive gradient in thin films technique (DGT) for the determination of labile Cu (II), Mn (II) and Zn (II) in petroleum produced water destined to reuse in agriculture. Samples were collected at the exit of the wastewater treatment plant (WWTP) (after separation oil/water and flotation) of a Petrobrás onshore production region. Basically, the laboratory experiments with DGT devices involved the evaluation of the behavior of the main variables of the technique for determination of analytes in the samples (diffusion coefficients, immersion time, fractionation of organic and inorganic species, and performance of diffusion gels with different porosities, among others). Also, experiments were conducted based on the solid phase extraction (SPE) protocol with Chelex- 100 resin using previously established protocols to support the study. During the project the possibility of in situ immersions in water treatment plants was evaluated. The DGT technique presented satisfactory results for determination of Mn in produced water, and can be used for in situ determinations. However, the results obtained for Cu and Zn show the need of additional studies

Ecologia de cultivos: caracterização dos aspectos ecológicos dos diferentes cultivos no município de Cristais Paulistas-SP

Planning is an essential instrument for the agricultural occupation of the lands, because it supports the activities of food production and raw materials. It must be driven by techniques that provide the sustainability of these activities, so that also ensures the environmental balance of agroecosystems. Lands misuse can be considered as one of the causes of frustration of agricultural activities. Thus, the occurrence of discrepancies between the effective use (real use) of the land and its agricultural aptitude can compete, in many cases, to the decrease of productivity, as well as for soil degradation. In this way, this research intends to study the relationship between the temporary cultivations, halfperennial cultures, perennial and its developmental environment, determining the edaphoclimatic characteristics of landscapes. From then on, a letter shall be subject to the use and occupation of the soil for agriculture in the municipality of Cristais Paulista-SP, aiming to describe the spatial organization of land use and vegetation cover, and emphasizing management and conservative practices. For that, climatic factors were characterized, fundamentally humidity, temperature and luminosity; edaphics, including parental material, chemical and physical properties, fertility, soil temperature and climatic zoning; biotic, referring to the suitability of different cultures or to be implanted; physical, such as geomorphology, slope, geology, hypsometry and hydrology; socioeconomic, in particular production and marketing seasons; and the way they all, together, affect the adaptation, distribution and production of crops. Using this information, the zoning of the area of study was done based on the 21 nominated groups obtained, in addition to recommendations and suggestions for handling each type of cultivation...

Análise cinemática e dinâmica para conversão de um VW saveiro em veículo elétrico

This work aims to kinematic and dynamic analysis of a VW Saveiro in order to estimate the power requested to the engine with the imposed movement conditions. Thus, the study will be the basis to the specification of the electric engine, on the conversion of the internal combustion vehicle into electric one. First of all, a literature review was done in order to understand the state of the art for this issue and come up with the technical features of the vehicle in question. The next step is the identification and calculation of all forces acting on the prototype in motion, from 0 to 120 km/h, in intervals of 10 km/h, under the defined conditions of path and time. Then, were determined the values of the torque and rotation of the components from the transmission system, as well as the engine power, for each speed range. The results show the most influential forces on the resistence of the movement in each speed range, and the behavior of the torque curve is verified. Finally, it was also analyzed the implementation of pinwheels on the frontal area of the vehicle, in order to convert wind energy into electrical energy to supply the lighting subsystem of the vehicle and the proposal was validated. Limiting the maximum speed of the vehicle to 90 km/h, it was finally concluded that the power of the electric engine should be 40 HP

Diagnóstico dos riscos e impactos ambientais da suinocultura no Ribeirão dos Pinheirinhos, município de Torrinha, (SP)

The porcine activity is characterized by its great pollution capacity, generally produce loads of waste that usually are released in superficial water or soil without concern for the consequences to the environment. With this in mind, this study aimed to adjust the porcine production to the protection of water resources, in particular, Ribeirão dos Pinheirinhos in the town of Torrinha (SP), through inventory and diagnosis of the environmental impacts already present and environmental hazards linked to the activity in question. To achieve the proposed objectives, the productions of porcine on the studied area were raised and georeferenced, viewed and analyzed according to the technical and scientific literature. The production visited showed to be at odds with the protection of water resources due to lack of technical criteria in the development of treatment systems and waste handling, indiscriminate use of effluent and waste in the fertilization of crops and the lack of knowledge of producers on the influence of porcine waste into the environment. Based on these results, were set guidelines for action in the environmental awareness of farmers, to stimulate voluntary and conscious initiatives of environmental conservation in the direction of settlement of the activity.
