This scientific research aimed at to analyse the susceptibility to debris flow of the watershed of Ribeirão do Roque (SP), focusing on the upstream areas of OSBRA pipeline. This is because, mass flow can cause damage to pipes, mainly due to conditioning hydro erosion of the land in the drainage crossings, including the undermining the banks of streams. Firstly, It was conducted a literature review, aiming to identify and understand the principal characteristics and conditions of debris flow. Secondly, the physical and anthropic factors and their respective weights of influence were selected and used to determine the mass flow susceptibility. It was selected the following physical factors: type and thickness of rocks, soil and unconsolidated materials; textural density; amplitude relief; relief slope; shaped valley; and shape of slopes. Such factors are present in the physiographic subdivision map of the study area. In addition, the anthropic attributes correspond to the classes contained in the land use map. Therefore, the physical and anthropic factors were integrated through the multi-criteria analysis in a GIS environment, generating a total susceptibility map of debris flow on the scale 1:50,000. The results showed that a significative part of the study area was classified as average susceptibility. However, it was identified areas with high susceptibility in the region in which the pipe cross the Ribeirão do Roque. Moreover, at which point the river presents a closed valley and a meander shape, without a fluvial plain that would be useful to attenuate the development of the process. Consequently, if a mass flow begins in any of these most susceptible regions located upstream of the pipe, the chances that the process develops by the river and causes the excavations of his bed are quite large. However, the pipelines cross these critical areas directly on the rock (diabase), which provides additional protection against possible ...

This study aimed to the development of cassava mashed with added maltodextrin of waxy maize starch as an alternative to the semi-ready product. The experimental design was completely randomized using blocks in 4x7 factorial, with three replications. The treatments were the combination of maltodextrin concentrations added in the cassava mass (0, 5, 10 and 15% on dry weight) with storage time (0, 2, 4, 6, 8, 10 and 12 days after preparation) and two condition (environment and refrigerated temperature). The variety chosen to the processing was the IAC 576-70. The data were subjected to variance analysis. The means were compared by Tukey test at 5%. The content of maltodextrin from waxy maize starch to 15% was effective in controlling the increase of texture. The mass of cassava with the addition of maltodextrin showed to be product of easy preparation, showin IAC 576-70g viability to be produced in industrial scale.

The use of rats in studies that seek to monitor the effects of physical exercise is fairly common, even in works that make use of overload. However, the correct determination of the training load is critical to success of studies. Thus, with the objective of verifying the correlation of total body mass of the rats with their respective strength, and the correlation of the 1RM test with test repetitions, 40 rats, 90 days old and weighing average 0,49 pounds underwent a program of adaptation to the water and then were subjected to tests to determine the maximal and submaximal loads. After measuring the total body mass and maximal and submaximal strenght, it was possible to observe directly proportional relationship between maximum strenght and total body mass of 0.97 (P ≤ 0.01), being the maximum muscle strength equivalent to 109% of the total body mass. Between muscle strength and mass submaximal muscle strength was also found direct correlation between the variables, allowing to conclude that the submaximal strength test and total body mass are effective tools in determining the training load of rats.

The mass media have a decisive function in formation of opinion and conduct of population. Among those, the television is a vehicle with great power of spread of information. The objective this study is to analyze the influence of media on occurrences regarding the aggressiveness some participants involved in event soccer, while spectators. The subject's attitude is determined by predominant factors, among them the influences of social and cultural way in that lives, as well as, of the education and sporting influences that it affects. The problem of violence in the sport, in the case of soccer, it cannot be addressed for total responsibility of media. However, collaboration is indispensable, for aspect positive and/or negative, depending on the interest in subject. The models of behavior in television could influence the spectator's behavior for a learning process, for example, the use of the language. Therefore, it is indispensable to rethink the roads of television, their ethical conducts and to discuss the philosophical sense of the crisis. Because, to reject the mass media is to deny the reality and social transformations. The extent of the Physical education, above all in the school, is a fundamental space for the teacher to intermediate the meaning of the sport, in this case, the soccer-spectacle, in social context and their relationships with the media, enlarging the process civilization, so much inside as out of field.

Aluminum Alloys are widely used as structural materials in the aerospace industry due to low weight, high mechanical strength and enduring corrosion resistance. Their resistance to corrosion is attributed to the rapidly formed stable oxide film (Al2O3) which spontaneously forms itself on the surface of the material. However, in the presence of aggressive ions, such as halide, Aluminum Alloys are subject to a localized process of corrosion. The electrochemical behavior of 7081-T73511 and 7050-T7451 Aluminum Alloys employed in the aerospace industry was investigated using a 0.6 M NaCl solution under the conditions of a controlled mass transport employing a rotating disk electrode. The theoretical limiting current density was determined by the Kouteki-Levich equation. The results confirmed that the inter-metallic Al7Cu2Fe acts as preferential cathode generating the galvanic coupling and the dissolution of the Aluminummatrix around it.

Obesity is characterized by an excess of fat on the body and can results several problems on the individual health. As an epidemic of modern times, the prevalence started to increase at an accelerated rate from the 90's in worldwide. Data on the epidemic in Brazil and medium-sized cities are scarce, and the monitoring of obesity is essential for development public policy. So, the objective was to analyze the individual factors associated with obesity such as age, gender, education, marital status, economic class and level of physical activity and make a monitoring of obesity in adults in the city of Rio Claro - SP. To do this, the survey was conducted longitudinally, consists of two times at an interval of seven years. At first (2008) were interviewed 1588 adults in the city of Rio Claro distributed throughout the city. At the second phase (2014/2015) was conducted a new interview with the same subject in 1588. In 2008, personal information collected and applied some questionnaires with the physical activity level, food intake and quality of life. To assess obesity in adults was calculated the body mass index (BMI) proposed by the World Health Organization (WHO) from the high reported weight and height. For older people it used a specific BMI. The prevalence was used percentages and their respective confidence intervals of 95%. For the incidence, was calculated by the formula of cumulative incidence, both stratified by personal characteristics (gender, economic class, education, marital status and age). Thus it was observed that there was an increase in the prevalence of obesity in 2008 (19.0%), increasing to 26.7% in 2015. The cumulative incidence was 14.4% in the range of 7 years. As for the groups, we observed a significant difference between economic class and obesity being less prevalent among people of class D / E. Regarding marital status, it was observed that married / cohabiting have a higher prevalence. Therefore, we can conclude...
