The aim of this study was to evaluate the quality of weight measurements produced in Primary Health Care Centers in Botucatu and surroundings. 14 Health Care Centers were included, all of them located in four towns in the area of Botucatu (4,555; 5,656; 18,761 and 128,397 inhabitants). General conditions and scale calibration conditions found in those Health Care Centers were evaluated. In order to evaluate the weight accuracy obtained by the local team, 10 adult users of each Center were addressed by the rater during the service routine in order to get a new weight evaluation, immediately after the measurement made by the team. The statistic method applied for checking the weight measurement held in the Heath Care Center and the scales accuracy was the measurement error technique (MET). The results have showed that out of 19 scales, 6 of them overestimated the weight by 50 grams, 1 of them underestimated the weight by 200 grams and the others were accurate. Evaluated as a group, the result of the scale MET was 44.3g. Regarding the conformity of the measures obtained by the MET of the adults weighing in the Health Care Centers compared to the ones obtained by the researcher, the expected result was obtained in only one Center (< 100g). The results have showed data compromise, rather due to lack of health team training than due to the conditions of the equipment used for the measurement.

The main objective of this paper was to verify the influence of the organization and management in social responsibility the decision of adoption, choice, justification and implementation of innovation in elaborates of sugar, ethanol and energy companies of the midwestern state of São Paulo. Using multivariable analysis of principal components and clusters, the variables were analyzed and companies classified. Adapted to contemporary situations, the Freeman (1975) model of taxonomies was the parameter with research information in personal interviews by semi-structured questionnaires. The activities investigated were the existence of programs and organization to improve the welfare and quality of life to employees and family (leisure, culture, health, self-knowledge, values, beliefs etc.), program and social volunteering organization for the community, programs and organization to encourage the training of educators and extension education and incentive programs and organization to research and scientific production. It was concluded that the best companies which included, in their organization structures, management practices embodied in social responsibility.

The aim of this study was to evaluate the evolution of calibration and maintenance practices for crop sprayers on soybean production areas in Brazil, in the 2006 and 2007 seasons, based on the Project IPP data. Therefore, the evaluation covered issues related to calibration, maintenance condition and the main components of 103 sprayers distributed in the following states: Rio Grande do Sul (35), Paraná (60), and, Mato Grosso do Sul (8). The evaluations were done at the rate of one sprayer per farm. The most frequent problems were related to the pressure gauge, spray leaks and calibration errors greater than 50% of the desired volume rate. The analysis of the application rate showed a tendency for the farmers to apply volume rates below the desired value. In 2006 the errors of the application rate were significant, with 70.4% for Rio Grande do Sul State, 74.5% for Paraná State and 37.5% for Mato Grosso do Sul State. In 2007 there was a reduction of errors, with averages of 50.0% for Rio Grande do Sul and 66.7% for Paraná. In general terms, the results showed improvements on the use, maintenance and calibration processes for crop sprayers on the areas covered by the Project IPP, with reductions on average indexes for calibration errors, leaks and bad tips, among other issues.

The objective of the study was to analyze the features of the relief through the variables: maximum altitude (HM); mean altitude (Hmd); minimum altitude (Hm); altitude range (H); average slope length (CVm); minimum length of run-off (Cd) and average steepness of circular samples (I) of the Capivara River Watershed – Botucatu (SP). A total of 4 circular samples were obtained per unit of soil (Quartzipsamment alfisol oxisol - RQ, Udox - LVA and Udorthent - RL). Multivariable analysis and aerial color photographs of 2000, Brazilian Chart and Soil Chart of Botucatu city-SP were used for data analyses. Soil differentiation was performed using the Student-t Test for analyzes of orthogonal contrasts among means of the three soils and analysis of groupings and major components. The grouping analysis of the variables of relief differentiated 75% of LVA and 100% of RL and RQ soil circular samples. The most efficient parameters of relief for differentiation of soils according to their order of importance were as follows: HM, Hm, Hmd and H.
