title: Treatment optimization of greywater from the combined use of chemical coagulants

description: ABSTRACT With the growing demand and shortage of water, efforts are needed to enable alternative sources of supply. Thus, this work was focused on optimizing the treatment of greywater by associating the chemical coagulants aluminum sulfate and ferric chloride, to enable their reuse. Therefore, the research was divided into three stages: characterization greywater from basin and shower of a single-family residence; assessing the combined use of aluminum sulfate and ferric chloride, prepared in 5% solution for the treatment of greywater, optimizing the concentrations of chemical coagulants applying Central Composed of Rotational Design and evaluating the data via Methodology Surface Response and Global Desirability; and evaluating the effectiveness of the proposed treatment, comparing the optimum dosages determined with laboratory tests. The results indicated that the combination of aluminum sulfate (concentration 0.470 g.L-1) and ferric chloride (concentration 0.115 g.L-1) potentiated treatment, achieving a removal of greywater turbidity of up to 94%; also, thermotolerant coliforms and residual chlorine were reduced, making it possible to reuse them in the discharge of toilets and in irrigation.

title: MAXIMUM HEART RATE MEASURED VERSUS ESTIMATED BY DIFFERENT EQUATIONS DURING THE CARDIOPULMONARY EXERCISE TEST IN OBESE ADOLESCENTS

description: ABSTRACT Objective: To compare the values of measured maximum heart rate (HRmax) and maximum heart rate estimated by different equations during the cardiopulmonary exercise test (CPET) in obese adolescents. Methods: This is a cross-sectional study. Adolescents aged between 15 and 18 years old, with obesity (BMI Z-score&gt;2.0) were included. Demographic and anthropometric data were collected, followed by CPET, recording HRmax. The highest heart rate reached at peak exercise was considered as HRmax. The comparison between measured and estimated HRmax values was performed using four previous equations. Descriptive statistics and the ANOVA test (Bonferroni post-test) were used. Results: Fifty-nine obese adolescents were included, 44% of them male. The mean age was 16.8±1.2 years old and the BMI (Z-score) was 3.0±0.7. At peak exercise, the mean HRmax (bpm) was 190.0±9.2, the respiratory coefficient was 1.2±0.1, and the VO2max (mL/kg/min) was 26.9±4.5. When comparing the measured values of HRmax with those estimated by the different formulas, the equations “220-age”, “208-0.7 x age” and “207-0.7 x age” were shown to overestimate (p&lt;0.001) the measured HRmax results in obese adolescents. Only the “200-0.48 x age” equation presented similar results (p=0.103) with the values measured in the CPET. Conclusions: The findings of the present study demonstrate that the equation “200-0.48 x age” seems to be more adequate to estimate HRmax in obese adolescents.

title: Evaluation of the behavior of hot-recycled asphaltic mixtures with reclaimed asphalt

description: ABSTRACT The objective of this study is to evaluate the technique of hot recycling in asphalt mixtures relative to the mechanical properties, for the purpose of verify the adequacy of their employment in substitution of virgin granular material for Reclaimed Asphalt Pavement (RAP) in different percentages, for the application in layers of pavement. To achieve the purpose of this study, laboratory tests were made to evaluate the mechanical properties and adhesiveness of mixtures containing 10% addition of RAP, 20% and 30%, compared to a reference mix without RAP. For stiffness evaluation were used resilient modulus tests (RM) and uniaxial dynamic modulus test. Besides these tests was performed the indirect tensile strength tests (RT) and Flow Number test (FN) for mechanical evaluation, damage tests induced moisture through the Modified Lottman test and Cantabro abrasion, for evaluation of the properties of adhesion and cohesion of the mixtures, respectively. Analyzing the results, an important economy of asphaltic binder was observed, whereas the RAP contains aged binder It´s possible to reduce the new binder content between 12.9% and 35.7% for mixtures with 10% and 30% recycled material, respectively. The experiment indicated the RAP addition affects the modulus and increases the stiffness of the mixtures; the FN test showed the resistance gain to the permanent deformation of the mixtures as well as there were no significant problems of adhesion, in other words, the losses are insignificant and do not compromise the use of this material.

title: Health via consumption: the idealized representation of housewives, mothers, and wives in household economics manuals and magazine advertisements in O Cruzeiro and Manchete, 1940-1960*

description: Abstract The relationship between the representation of the idealized woman in the household economics manuals and the female figures of the advertisements published in O Cruzeiro and Manchete magazines between the 1940s and 1960s is analyzed. With different editorial proposals, manuals and magazines were predominantly directed at women who performed the duties of wife, housewife, mother and maid. Despite this clear definition of roles, there existed some tension around the female figure who was no longer tied to the home and already occupied jobs in the public sphere. Consumption became the common denominator among these different women. The new products guaranteed health, comfort and practicality to all concerned.

title: Timber and concrete composite system: a numerical and experimental approach for high temperatures

description: ABSTRACT The aim of this work was the evaluation of the temperature profile in two composite timber and concrete beam with cross-section T and metallic connection system subjected to high temperatures. The connection system, in this case, was performed by use of steel bars with 12.5 mm diameter, equally spaced, along the concrete-timber interface. The cross section T of the beam consisted of a timber piece with dimensions 5 cm x 15 cm connected of a concrete slab with 30 cm x 5 cm. To the composite beams, a total time of fire exposure equal to 40 minutes was considered. The numerical modeling of the system was carried out using the ANSYS software [1], version 10.0. The results of numerical simulations were compared with the experimental results of temperature obtained by the two composite beam, which were instrumented with thermocouples and subjected to high temperature in a horizontal furnace constructed on EESC/USP for this purpose. The numerical and experimental results showed good agreement in this case. As a result, the temperature profiles are shown in cross section for various heating times and all numerical modeling strategy and the finite element used to determine the temperature profiles.

title: Participative research and comprehensive child healthcare promotion strategies in the Brazilian National Health System (SUS)

description: The article discusses methodological aspects of an investigation aimed at promoting the involvement of participants as a challenge. We were interested in understanding how family health teams made sense of the child handbook - Caderneta de Saúde da Criança, and child development. The intervention-research promoted the sharing of viewpoints among researchers and providers in focal groups with the use of narratives making it possible for the participants to become key players of the proposed investigation. The implementation of the strategy promoted: 1) the greater ownership of the instrument, 2) the deepening and repositioning regarding crystalized issues in the functioning of teams, and 3 ) the validation of research results. These results indicate that there is a contribution of participatory research to the consolidation of SUS because they propose access to a common plan as methodological strategy and promote greater engagement of the teams in relation to the proposed themes.

title: Evaluation of soil-cement blocks for sustainability and habitability in accordance to the Brazilian standard ABNT NBR 15575

description: ABSTRACT The building sector is responsible for significant consumption of natural resources. Sustainable buildings contributes to the reduction of environmental impacts such as energy consumption, soil, and water and air pollution. In this scenario, raw soil as a building material has become an alternative for the development of sustainable buildings. Raw soil is cured without burning. Raw soil mixed with Portland cement, pressed and stabilized produces soil-cement blocks and they are already regulated by the Brazilian technical standards association (Associação Brasileira de NormasTécnicas – ABNT) and possesses many advantages related to its manufacturing and use. To increase its acceptance and verify its efficiency as a building material for social housing, it is necessary to investigate its properties and performance. The present study aimed to evaluate the performance of an external vertical sealing system composed of hollow blocks of soil-cement without structural function for social housing, following determinations of ABNT NBR 15575, focusing on the requirements of habitability and sustainability. It was analysed tightness against rainwater and water permeability, habitability requirements, and durability, sustainability requirement, through heat action and thermal shock testings. The system met limits set by standards for tightness against rainwater and heat action and thermal shock, but not for water permeability. The vertical sealing system composed of hollow blocks of soil-cement has potential for application in the construction, but there is still need for more studies on the system.

title: Diagnosis of the use of wood as construction material in the city of Mossoró-RN/Brazil

description: ABSTRACT Wood as a building material has always been present in the development of society. It is a material that can practically be found during all stages of the construction and the construction industry is one of the sectors that has higher consumption of this feature. In Mossoro-RN, the construction industry is an important sector of the economy, causing an intense wood consumption. It is possible to see the urban growth of the city just walking through the main neighborhoods in development, which are real construction sites. This research aims to evaluate the main uses of wood by the civil construction of the city of Mossoro-RN, the main wood species used and the final destination that is given to the waste generated by its use. The information was collected through survey data with companies that sell wood and construction companies in the city. It was observed that the wood is used more as a temporary item than a permanent item in the construction, where it is applied almost exclusively as material for roofing and wood frames. The wood consumption for construction in Mossoró has a preference to the use of Maçaranduba wood (Manilkara sp), a tropical wood originating from the Pará state, however some wood shops had already start to negotiated wood from planted forests from Minas Gerais and Paraná states. Nowadays, the wood waste is collected by specialized companies. Still, there isn't an awareness about recycling and reuse of this kind of material, especially among the construction companies in Mossoró.

title: Incorporation of nanosilica in cement composites

description: ABSTRACT The incorporation of the nanosilica has been studied as an alternative to improve the characteristics of cementitious materials because tends to increase the pozzolanic reactions and fill the interstitial spaces, decreasing the porosity and improving the compressive strength. In this context, the present study has the goal to evaluate the mechanical behavior and the microstructural characteristics of three cementitious composites: the reference e two with different levels of nanosilica dispersed in polycarboxylate (NDP), 0.2 and 0.4%, in relation to the cement mass. The mechanical behavior was evaluated through the compressive strength test and tensile test (Brazilian denomination). Furthermore, were done water absorption tests and microstructural analysis by Scanning Electron Microscope (SEM). From the analysis of the results, it was verified that the addition of NDP improved the mechanical properties and the microstructural characteristics of cementitious composites. The NDP content (0.4%) showed better results at 28 days, presenting a 55% increase in compressive strength, 79% tensile test and a 40% decrease in the absorption of water, in relation to the reference, possibly through the NDPs performance. However, when analyzing the incorporation of the two NDP contents, it was verified that when the content was doubled there was no significant improvement in the compressive strength, since the incorporation of 0.2% of NDP increased the compressive strength in 53% in relation to the reference. As for the microstructural analysis, a refinement of the structure was verified from the incorporation of NDP but no differences between the two incorporation was visualized.

title: Comparative study between strain gages for determination of autogenous shrinkage

description: ABSTRACT The Carlson-type strain gages are the most suitable for the measurement of autogenous shrinkage. However, your high cost is usually a limiting factor for your employment. A more economical alternative would be the use of Self-Temperature-Compensation Gages to be embedded in concrete. The main objective of this work was to verify if Self-Temperature-Compensation Gages can be used instead of the Carlson type to determine the autogenous shrinkage in high performance concrete. It was carried out measurements of the autogenous shrinkage, for the same concrete mix, using the two types of extensometers. The difference in the means of the autogenous shrinkage results between these two types of extensometers was typically less than 10x10-6 m/m.
