Purpose - This study examined the relationship between environmental management practices developed at a campus of a Brazilian university (University of Sao Paulo) and the greening of its organizational culture. The paper aims to discuss these issues.Design/methodology/approach - This article presents a theoretical background based on the concepts of environmental management, organizational culture and environmental management in higher education institutions. The main framework of this research is the model proposed by Harris and Crane.Findings - The studied university has an environmental management program that is sometimes constrained in the following ways: the university bureaucracy and hierarchy; the main performance indicators for lecturers and professors are based on scientific production and publication, giving them little time for complementary activities; and some units develop their own environmental management practices, but they are not disseminated as best practices for use by other units. Some academic units showcase the proactive actions of professors who incorporate environmental management into their daily activities. The general perception is that the phrase environmental management is almost synonymous with solid waste management.Originality/value - This research details the first Brazilian application of the Harris and Crane model. It contributes an original analysis of environmental management and green organizational culture of a Brazilian university, an organizational type that has seldom been studied to date.

In this paper we present ongoing research in which we approach the regulatory role of language in role play in children aged six and seven. In research, we seek an understanding of the relationship between language, ownership and complexity of the children's game. The hypothesis guiding the research is that the dialogical relations between children and adults and among children, while playing, contribute to children's learning game. Procedures are being used interpretive ethnographic research that focuses on the human meaning of social relations, waged by the subjects in a particular historical context and its elucidation and exposition by one researcher. This approach allows closer studies of Vygotsky and Bakhtin scholars of language that emphasize the regulatory role of language in human relationships and value the dialogic exchange between researcher and researched; active subjects of the research process. The data were produced by means of observation and interview, in a field diary records, photographs and audio recordings. They are being screened in thematic groups and analyzed using interpretative narration. The participants were two teachers and two classes of the first year of an Elementary school (EMEF) School of Municipal Elementary School Crane, State of Sao Paulo, totaling 45 subjects. Bearing in mind the above assumptions, are presented and analyzed data that allow to anticipate some results.

In 2010 Brazil produced about 60.8 million of municipal solid waste, an amount 6.8% higher than in 2009 and six times the rate of urban population growth recorded in the same period. According to a study by the Brazilian Association of Companies of Special Wasteand Public Cleansing (Abrelpe), the average waste generated per person in the same period the country was 378 Kilograms, an amount 5.3% higher to 2009 (359 Kg). The total reached 60.8 milion tons of waste, 6.5 million tons were collected and not end up inrivers, streams and vacant lots. Of this total production, 42.4% or 22.9 million Tons, did not receive proper destination and destiny had dumps and landfills. The data show that the country is in upward trend in waste generation, but did not advance the appropriate destination at the same pace. The waste thus throw open cause public helth problems, such as proliferation of disease vectors (flies, mosquitoes, cockroaches, rats, and others). Generation of odors and especially the pollution of soil, surface water and groundwater through slurry ( liquid black, smelly and high pollution potential produced by the decomposition of organic matter contained in waste), affecting the water. This Study shows the popper closure of the areas, wich long has been degrading our natural resources, not to cause damage to nature and therefore society

Aedes (Stegomyia) aegypti is a species of mosquitoes known to be the vector of diseases such as dengue and yellow fever, and a better understanding of aspects of their biology can help in the establishment of control strategies for the same. Several previous studies showed that temperature significantly affects the development of immature stages of insects. In general, higher temperatures (up to a threshold) accelerate the development of insects, and lower temperature retards the same. This rule also applies to mosquitoes, including Ae. aegypti. But not still know the effects of daily variation of temperature on the developmental stages of mosquitoes. And this detail is very important, since in natural breeding or artificial, The mosquitoes usually face temperature variations over a single day, which should interfere with its development until the emergence of the adult forms. For this reason, the objective of this study is to analyze the effect of alternating temperatures on the development of Ae. aegypti. To conduct the study, adults were collected active in the neighborhood Bela Vista Campus of UNESP - Rio Claro, SP, using a sweep net or using ovitraps for immatures, and the active search for breeding. Individuals collected were kept under experimental conditions in the laboratory. The adult samples were identified to species level, were considered for the experiments, only samples of Ae. aegypti. The insects were housed in plastic cages, suitable for creating flies. These were fed with sugar solution and blood meal on alternate days. The eggs obtained were used in the experiment with four different temperature regimes. The data collected were analyzed by evaluating whether the different treatments influenced the development of immature to adult, performing the Kruskal-Wallis test and the statistical software BioEstat. Statistical analysis of the sex ratio... (Complete abstract click electronic access below)

This work aims to determine the stresses acting on the main beam of a crane to transport steel coils of up to twelve tons. To determine the stress it was made a revision of the knowledge of the mechanics of materials to apply the analytical method. Following a review of the finite element method is made to understand the same. To complete the study it was used the commercial software ANSYS to determine the stresses by finite element method, the program provides images that help to better understand the results obtained. With the results a comparison of the values of the tensions between the two methods (analytical and finite element) was made. To assist in the calculations it was used the NBR 8400, 1984 (Calculation of Lifting Equipment Load)

The finite element method is of great importance for the development and analysis of a new product being designed or already on the market, and that requires some specific request or special application. The tower crane, being an essential equipment for modern construction to increase productivity and safety on construction sites, is required for many types of special applications day after day, in many kinds of work. Paying attention to this growing need for handling special projects for the tower crane, faced with the importance and necessity of development and improvement of knowledge in more accurate and practical calculation methods such as the finite element method , for greater agility and precision in the response to a new project. The tower crane is defined by the maximum load moment that it can act with a certain amount of load. The tower crane which will be analyzed in this work , for example, is a tower crane with a resulting capacity of 85 Metric Tons which are considered basic dimensions data of a fisical tower crane of a crane company Liebherr in Guaratinguetá . Thus, the project analysis will begin with the threedimensional representation of the crane lines with AutoCAD software , conversion of this model to the format accepted ANSYS Workbench and completion of 3D modeling of structural components in Design module ANSYS software. After structural modeling is completed, the simulation is performed in static simulation of ANSYS Workbench software mode. The standards will be adopted to DIN (Deutsches Institut für Normung) and EN 14439 (Europäische Normung 14439) and some NR 's related to specific security class of tower cranes, which will be referred throughout the work
