title: Identity, Representations and Performativity: Words, Actions and Crucifixion in the Gay Pride Parade in São Paulo

description: ABSTRACT The objective of this research report is to investigate and discuss the implications of the hostile and offensive comments of different Internet users and the forms of representation of the staging of the crucifixion of Christ by the model Viviany Beleboni, during the Gay Pride Parade of São Paulo in June of 2015. In addition to the concepts of Hall (2008) and Woodward (2008) related to representation and identity, during the analysis of the data were also mobilized the studies of speech acts and performativity by Austin (1962) and Rajagopalan (2012). The results of this research corroborate the theoretical assumptions used, according to which language serves to alter and create realities and not only to describe or represent it. This study also provided an understanding about how the dichotomization of different identity aspects can benefit one group over others.

title: PHYSICAL, MECHANICAL AND THERMAL BEHAVIOUR OF ADOBE STABILIZED WITH THE SLUDGE OF WASTEWATER TREATMENT PLANTS

description: ABSTRACT The need for treated water is essential for life. With the constant increase in population, the most common way to purify surface water is through conventional water treatment plants (WTPs). The high volume of residue (sludge) generated in this process is most often returned to the catchment site, negatively affecting the ecosystem. The sludge of WTPs is similar to soil because it is composed of inorganic solids. Adobe is a construction material made from water and soil without the burning process, so it is considered sustainable, recyclable, and energy-efficient and can be stabilized with various materials. Therefore, the objective of this work is to develop adobes using the sludge of WTPs and to analyse their physical, mechanical and thermal properties. Adobes were produced with five concentrations of sludge by mass: 0, 1, 3, 5 and 7%. It was observed that with the increase in the sludge concentration, there was an increase in the capillarity and a decrease in mass, the water absorption was limited to 3% of sludge, and there was an increase in the bulk density. The linear shrinkage, thermal conductivity and compressive strength were not influenced. The addition of WTP sludge altered some properties of adobe. The use of WTP sludge in adobe is limited to 3%; above that, the adobe becomes unstable in relation to water. Therefore, the use of WTP sludge in the manufacture of adobe is feasible in controlled concentrations and is a sustainable use of the residue.

title: Proposal of a performance measurement system for sustainable management on construction site

description: Abstract Although several methods for sustainable management on construction sites have been developed in recent years, not enough tools are available to measure and evaluate its performance. The aim of this study is to propose a measurement system to evaluate the performance of sustainable management on construction sites, determining good practices as a strategy to support the implementation of those indicators and the mitigation of environmental impacts. The research approach adopted was Design Science Research, involving the following steps: (1) a literature review, to identify good practices and indicators proposed in this research study; (2) data collection, to evaluate the use of the proposed indicators; (3) pilot implementation of the proposed performance measurement system on a construction site; and (4) evaluation of the performance measurement system, expected positive impacts, implementation and monitoring of actions, and the usability and ease of the SI. The main contributions of this study are the development of the Performance Measurement System for Sustainable Management in Construction Sites (SIGS), consisting of 26 indicators, in which objective criteria were established to evaluate the environmental impacts; identifying good practices for reducing environmental impacts; and the identification of facilitating factors and hindering factors for SIGS implementation.

title: NUMERICAL STUDY OF VISCOPLASTIC FLOW IN A T-BIFURCATION: IDENTIFICATION OF STAGNANT REGIONS

description: Abstract Identification of stagnant regions of viscoplastic fluid flows in production lines and equipment is of paramount importance owing to potential material degradation and process contamination. The present work introduces an assessment strategy to identify, classify and quantify unyielded regions with the objective of optimizing the flow conditions with the purpose of minimizing stagnant regions. Flow of Carbopol® 980 in a T-bifurcation channel is adopted to illustrate the procedure. The rheological behavior of Carbopol® 980 was simulated using the Herschel-Bulkley viscoplastic model regularized by Papanastasiou’s exponential approach. The analysis shows that three distinct types of stagnant unyielded regions take place in the bifurcation channel depending upon the Reynolds condition. Furthermore, the rheological characteristics of the fluid indicate the existence of an ideal Reynolds condition which allows the smallest flow stagnant area at the bifurcation zone.

title: Alzheimer's disease and sleep disturbances: a review

description: ABSTRACT The association between Alzheimer's disease (AD) and sleep disturbances has received increasing scientific attention in the last decades. However, little is known about the impact of sleep and its disturbances on the development of preclinical AD stages, such as mild cognitive impairment. This review describes the evolution of knowledge about the potential bidirectional relationships between AD and sleep disturbances exploring recent large prospective studies and meta-analyses and studies of the possible mechanisms through which sleep and the neurodegenerative process could be associated. The review also makes a comprehensive exploration of the sleep characteristics of older people, ranging from cognitively normal individuals, through patients with mild cognitive impairment, up to the those with dementia with AD.

title: Occurrence of violence in the elderly and its associated factors

description: ABSTRACT Objective: to analyze the occurrence of violence in the elderly and its associated factors in the city of Betim, Minas Gerais. Method: cross-sectional study constituted by a population survey conducted through structured interviews. The sample was stratified by clusters and included 178 elderly people at the end. Data were analyzed by the chi-square test and was performed a Correspondence Analysis. Results: The most prevalent forms of violence were: lack of access to social rights (31%), verbal violence (22%), moral/psychological (19%), lack of care (16%), physical violence (6%), sexual (3%) and discrimination (3%). Women suffered more abuse than men and violence had greater association with the degree of depressive symptoms. Conclusion: our research has direct implication for the sectors interested in coping with violence in the elderly, especially for nurses, because it shows violence is part of a cycle with characteristic associated factors that conforms a model nested mainly in the family relationship.

title: Homemade laparoscopic simulator

description: Abstract Purpose: To describe a guide for the construction of a laparoscopic training simulator. Methods: Step-by-step description of an inexpensive and easy to assemble homemade laparoscopic training box, capable of simulating the laparoscopic environment in its peculiarities to enable technical skills training. Results: The total cost of the materials for the construction of the simulator was US$ 75.00 (about R$ 250.00 “reais”) and it can be reduced to US$ 60.00 if the builder judges that there is no need for internal lighting. The use of real trocars imposes the same challenges as real surgeries regarding positioning, visibility and limitation of movements. Conclusion: The proposed economical and efficient alternative can contribute to the teaching and practice of laparoscopic surgical technique worldwide, benefiting surgeons and patients.

title: Limitations of VEINES QOL/SYM for discriminating chronic venous insufficiency severity

description: Abstract Background The Venous Insufficiency Epidemiological and Economic Study - Quality of Life/Symptoms (VEINES-QOL / Sym) questionnaire was developed to evaluate the quality of life of individuals with chronic venous insufficiency (CVI), but it has shown limited sensitivity for discriminating between people with different of disease severity. Objectives a) to propose a new formula for calculating the VEINES-QOL/Sym score and to evaluate whether this new score is capable of discriminating disease severity; and b) to evaluate the association between VEINES-QOL/Sym scores and disease severity. Methods Ninety-eight participants with CVI of both sexes, aged 60.73 ± 14.11 years, answered the Portuguese Brazilian version of the VEINES-QOL/Sym questionnaire. The new score was calculated by transforming the original scores to a 0 to 100 scale. Discriminant analysis was used to test the capability of the original and modified VEINES-QOL/Sym scores to discriminate between and correctly classify groups characterized by the clinical, etiological, anatomical and pathophysiological classification (CEAP). Alpha of 5% was defined as the cutoff for significance. Results There were no significant differences between CEAP groups in terms of the original or modified VEINES-QOL/Sym scores. Discriminant analysis was also unable to correctly classify CEAP groups, using either original or modified scores. Furthermore, there were no associations between CEAP classifications and scores obtained using the questionnaire. Conclusions The VEINES-QOL/Sym proved to have limitations for assessment of the quality of life and symptomatology of people with CVI at different stages.

title: NUMERICAL SIMULATION OF COAL GASIFICATION IN A CIRCULATING FLUIDIZED BED GASIFIER

description: Abstract This paper presents a 3D full-loop simulation of a circulating fluidized bed gasifier. The model is validated with experimental results from the literature. The validated model is thereupon used to compare Bubbling Fluidized Bed (BFB) and Circulating Fluidized Bed (CFB) gasifiers to highlight the effect of a change in fluidization regime from bubbling to fast fluidization on hydrodynamics, temperature and gas composition. Feed temperature as well as Air/Coal (A/C) and Steam/Coal (S/C) ratios are kept constant, whereas the velocity of the feed (Air-Steam) is increased so as to get into the fast fluidization regime. It was concluded that the flue gas from the CFB is richer in desired gases, i.e., CO and H2 than that from BFB. H2 remains approximately the same, CO2 and CH4 decreased to a negligible amount and CO approximately doubles when the regime is changed. In addition, tar content in the gas also decreases.

title: Assumptions of good practices in home care for the elderly: a systematic review

description: ABSTRACT Objective: To synthesize the knowledge produced on best nursing practices in long-term care for elderly at home, in order to promote healthy aging. Method: A systematic review, based on the Joanna Briggs Institute’s proposal: without restriction of dates; in the English, Portuguese and Spanish languages; conducted in PubMed, CINAHL, LILACS, Embase and Scopus databases. Results: Among 453 articles identified, 16 were included in the review: seven qualitative and nine quantitative, published between 1996 and 2015. The synthesis of the data identified as best practices identifies a premise of care centered on the elderly and the inclusion of the elderly, family and nurses as agents of this care. Conclusion: According to evidence, good practices in gerontological and nursing home care fundamentally depend on constant planning and reorganization, so that they are indeed comprehensive and contextualized. Thus, providing care will be reasoned by and driven to the elderly, based on their specific and global needs, favoring a process of healthy and active aging.

title: Hardening and Dynamic Recovery During Hot Compression Test of Copper Simulated as Viscoplastic Material

description: The Norton-Bailey equation was used to simulate by finite elements the hardening and dynamic recovery of copper during the hot compression tests. The constants of Norton-Bailey equation were determined from the Voce-Kocks model. The simulation assumes a Mortar Contact with Coulomb friction and axial symmetry. Numerical results were compared with experiments. Six compression tests were carried out at 804 K, three with a strain rate of 0.1 s-1 and three with a strain rate of 1 s-1. The results show: The differences between the experiments and the simulations are less than 7.69% for strain rates of 0.1 s-1, and less than 0.67% for strain rates of 1 s-1. This shows that the simulation of hardening and dynamic recovery of hot copper is possible with the Norton-Bailey equation. Better numerical results were obtained when the behavior of copper is typical of hardening and dynamic recovery, and this happen for high values of strain rates.
