Thermogravimetric analysis is one of the most common instrumental techniques used for the characterization of pastes, mortars and concretes based on both calcium hydroxide and Portland cement. Important information about pozzolanic materials can be assessed concerning calcium hydroxide consumption and the formation of new hydrated products. Nevertheless, in some cases, problems associated with the overlapped decomposition processes for hydrates make the analysis of obtained data difficult. In this paper, the use of high-resolution thermogravimetric analysis, a powerful technique that allows separating decomposition processes in analysis of hydrated binders, was performed for spent FCC catalyst-Portland cement pastes. These pastes were monitored for 1, 4, 8 h and 1, 2, 3, 7 and 28 curing days. In order to study the influence of the pozzolanic material (spent FCC catalyst), Portland cement replacements of 5, 15 and 30 % by mass were carried out. The presence of spent FCC catalyst in blended pastes modified the amount and the nature of the formed hydrates, mainly ettringite and stratlingite.

Objective: to describe the profile of non-fatal cases related to interpersonal violence treated in an emergency care unit of reference that serves seven municipalities of the state of São Paulo, Brazil, from 2008 to 2010. Methods: the study data came from the cases reported from the Epidemiological Vigilance in Penápolis-SP to the Brazilian Information System for Notifiable Diseases; variables were shown according to the Notification/Investigation Individual Formulary of Domestic, Sexual, and/or other Types of Violences. Results: 109 occurrences were studied; most of the victims were young and female (93.6%); and the aggressors, mostly were men (57.8%), partners or relatives/acquaintances of victims. Physical violence was the main form of aggression (93.6%), principally in the home (67.9%), on Sunday (16.5%), between 6:01pm and 12:00pm (57.8%). Conclusion: the cases reported had a consistent profile of domestic family violence against women, different from other studies about interpersonal violence in large cities and metropolitan regions

Analysis of variability of rainfall UGRHI-17 is important because it is located in an area of agriculture. This importance is through a better dialogue between research and farmers, who can see this, an analysis of events that impact your direct planting. Noting the periodic occurrence of these events, agriculture can be prevented by protecting your planting and ensuring a good harvest. The analysis and observation of the entire region is through the location of the stations, which allow a more complete analysis if they are well scattered throughout the unit. Through calculations parse wet and dry years, and this work will be given emphasis to the wet years. They presented the climatological average above average extracted for all seasons. These wet years are generally associated with events such as El Niño and the intensification of SACZ. For these years, was also observed the spatial distribution of rainfall through isolines. How to deal with regional data, the Geostatistics was a resource used in this work to make the analysis more complete and closer to the actual data from the wide year-to-interannual scale. Their adoption is in the preparation of contour, making the spatial distribution more accurate.

The Physical Activity Program for Persons with Special Needs (PAFIPNES) is a extension project developed since 2002, and operates in secondary care to the health of obese, diabetic and hypertensive women. This offer exercise programs supervised by physical education professionals, together with a multidisciplinary health team that works in a Health Basic Unit of São José do Rio Pardo/SP. Their actions included interventions to improve general health status and stimulate the adoption of a more active lifestyle. In addition, the PAFIPNES serves as an internship site for scholars of Physical Education can acquire knowledge and skills that enable them to act on basic health care of patients with Non Communicable Diseases, as mentioned above.

The aim of this study was to investigate the performance of an experimental rainwater treatment system for non-potable uses. Without the first-flush discharge it was expected to control the quality of captured rainwater and to minimize the rainwater by-pass caused by the first-flush strategy. A full-scale direct filtration unit was operated and a solution of natural corn starch was used as the primary coagulant. The color, turbidity e coliform efficiencies of the unit was analyzed based on filtration loads and the net water production was estimated. The results pointed out turbidity removal up to 70.8% and color removal up to 61.0%. The backwash of the filtering system was completed in 3 minutes at the rate of 1,440 m3/m2day with consumption of treated water from 0.5% to 2.2%, based on the potentially harvesting.

The main article aim was to investigate the collecting system of a dissolved air flotation (DAF) unit in pilot scale. Referring to the collecting system position, two options were analyzed: (i) top manifold and (ii) bottom manifold, pipes or plates. Qualitative and quantitative essays were performed, as image and stimulusresponse tests, respectively. The results of the essays standardized were adjusted by N-continuous stirred tank reactors in series and theoretical models of dispersion (low and high). The bottom manifold (plates with orifices) was more appropriate. The results pointed out that the N-continuous stirred tank reactors in series model was more adequate to describe the hydrodynamic behavior of the DAF unit.

The study of variability becomes increasingly important nowadays . Studying the behavior of rainfall before external events is of paramount importance. The region of Vale do Paraíba , it is important to study variability , since the region is influenced by the ocean and constant cold fronts that end causing precipitation during most months of the year . This study aims to analyze the variability in rain UGRHI - 2 by analyzing the interference of ENSO events / Southern Oscillation and the Convergence Zone South Atlantic (SACZ) in the amount and distribution of rainfall. The UGRHI helped were created for distribution and control of water in the state of São Paulo , divided watersheds were avoided so that problems such as poor distribution and water shortages in some areas of the state . To study variability , various software , including Excel , Variowin and R statistical package , the subroutine Climatol were used , with the goal of developing isolines showing the spatial distribution of rainfall anomalies in the years studied also the anomaly index was studied rain (IAC) , noting more effectively the years of positive and negative anomaly , with the purpose of studying the temporal variability of rainfall in the study area.

The article presents survey of public servants of a Higher Education Institution (HEI) that aimed to diagnose the presence of stress in this population, the stress phase in which individuals find themselves and the prevalence of symptoms, whether physical or psychological. This study aimed to characterize the symptomatology of the population experiencing stress and major stressors of the work context where participants act. The survey revealed that 46.6% of the participants are experiencing stress, mostly found in the resistance phase with predominantly psychological symptoms. Among the major stressors of work contexts, stood the physical environment of the workplace, sector infrastructure work, the process of professional performance evaluation adopted by IES, low recognition given to the work done and the small number of servers in certain sectors . The results revealed the presence of stress advancement of this sample and the need for appropriate policy actions and management practices of people who aim to act to minimize this phenomenon.

From the concept of Environmental Education proposed by I.U.C.N. in the 1970’s and considering some of the main teaching methodologies adopted in activities regarding Environmental Education, this paper aims to analyze the methodology named Pedagogy of the Project and presenting some alterations of this method, especially in relation to considered study unity: the watershed. Some teaching techniques are also presented, as well as didactic resources and considerations regarding the questions that can be developed for the students within the teaching or evaluation process. This purpose is complementary to others already existents and can be applied in many environmental or socioeconomics situations.
