Ostomy is an open surgical origin, when it is necessary to deviate temporarily or permanently, the normal transit of food and / or deletions. The patient with ostomy disposal is faced with changes in their physiology, also emerging on the need to care collection bag. This study aimed to analyze the quality of life (QOL) of people living with ostomy Intestinal (EI), who attended the Pediatric and Adult Rehabilitation Center of Rio Grande do Norte (CRI / CRA-RN). It is an analytical study with cross-sectional design and quantitative approach, accomplished with 89 people who had EI. The study was approved by the Ethics Committee of the Federal University of Rio Grande do Norte (CEP / UFRN), CAAE: 19866413.3.0000.5537. Held data collection in the period January-March 2015 using two instruments: an adapted general questionnaire covering socio-demographic, clinical and self-care and a specific instrument for assessing QOL of people with stoma titled as City of Hope Quality of Life - Ostomy Questionnaire (COH-QOL-Q), validated and adapted to Portuguese in 2010, composed of four areas, namely: Welfare Body (BEF), Welfare Psychological (BEP), Welfare (BES ) and Spiritual Well-Being (BEE). The collected data were entered into a database in Microsoft Excel 2007 spreadsheet application and processed in computerized software for descriptive and inferential analysis. The results showed that 83.1% had a colostomy and ileostomy 16.9%. Sociodemographic characteristics prevailed in males (57.3%), over 50 (57.3%), mulatto (46.1%), with presence of companion / a (57.3%), retired / beneficiaries (50.5%), monthly income above the minimum wage (68.5%) and who have studied up to elementary school (67.4%). Regarding clinical aspects, it was observed that the main cause that led to the making of the stoma was the neoplasm (59.6%) followed by trauma (21.3%). The sample showed people with stoma for more than six months (79.8%) of permanently (57.3%), in use sink equipment piece drainable (68.5%) of flat base (82.0%). With respect to self-care, 93.3% emptied and washed the bag alone (care related to hygiene) and 75.3% fixed the new exchange on the skin during the exchange (care related to the stock). Patients with more than six months of ostomy and had no partner (a) had higher averages of self-care related hygiene and purse. The average of respondents QoL scores was 68.90% for General QOL; 68.03% for the BEF; 68.38% for the BEP; 66.46% for BES and 75.41% for BEE. Among the aspects that influenced QOL included: physical strength, pain, suffering and gases (physical domain); appearance, care of the stoma and adaptation to new condition (psychological domain); isolation, interference in personal relationships and social activities (social domain) and going to church or synagogue, spiritual activities and positive change after ostomy (spiritual realm). Based on these results, it is concluded that this was a predominantly adult sample / elderly (between 50 and 70 years), with low education and the cause motivating the stoma, neoplasms. However, such findings did not pass at low percentage levels on the self-care capacity to deliver even at low QOL scores.

The treatment of wastewater is essential to human health. One of the most important steps is the disinfection treatment which uses chlorine to eliminate bacteria as required by environmental agencies. However, the identification of potentially toxic byproducts generated by this method, such as trihalomethanes, has stimulated the development of new alternative disinfection technologies. Among them, heterogeneous photocatalysis, TiO2 photocatalysis and electrochemical disinfection are considered suitable alternatives to the chlorination method. Thus, the present dissertation analyzes the evolution of active chlorine species in a synthetic NaCl solution and it is tested to treat a synthetic solution of the dye Reactive Blue 19 using boron-doped diamond (BDD) and ruthenium oxide (Ti/Ru0.3Ti0.7O2) as anodes. The indirect electrochemical process was discussed in terms of mineralization of the total organic load and percentage of color removal in order to evaluate the applicability of electrochemical technology. Electrochemical experiments were carried out with different current densities (25, 50 and 75 mA.cm-2) during 120 minutes. On the other hand, other important parameter in this study was the influence of the proportion sp3/sp2 on BDD anode on the performance of the evolution of active chlorine species which was investigated by electrolytic techniques (linear polarization), with the intention of determining the related training oxidizing species and consumption energy to chemical or electrochemical reactions. From the results, it can be noted that the BDD electrode showed better efficiency throughout the electrochemical process.

Vegetable oils are characterized as important raw materials in the supplying of natural substances of interest pharmaceutical, food and cosmetic industry. Sunflower oil stands out for its important composition present in unsaturated fatty acids such as oleic acid (C18:1) and linoleic (C18:2), responsible for many health benefits. The main objective of this study is obtain enriched fractions in unsaturated compounds from refined sunflower oil. The oil used in this study was characterized by the determination of some properties, like iodine number, acid number and viscosity. A transesterification was done to transform the triglycerides into their corresponding methyl esters of fatty acids. These was submitted the molecular distillation process, for present as an efficient alternative to separation and purification of these substances, using high vacuum and low temperatures. Of the esters fractions that was obtained, were analyzed by gas chromatography. The experimental design technique was used to evaluate the influence of the temperature variation of evaporation and condensation system on the percentage obtained residue. The evaporator temperature proved to be the most influential variable on the studied response. The optimized conditions for the answer was studied at 100 °C for evaporator temperature and 10 °C for the condenser temperature. The graph of "split ratio" showed that for the lowest flow feed (1 mL/min) and higher evaporator temperature (110 °C) was obtained in the largest fraction of distillate. It also used the study of the influence of evaporator temperature on the concentration of unsaturated compounds. The best operating conditions for temperature was 90 °C reached 82.21 % of unsaturated compounds. Elimination curves of the unsaturated compounds present in the distillate stream were obtained. The simulation results of the molecular distillation process of sunflower oil showed the concentration profiles for three different feed flow rates. The speed, temperature and thickness profiles of the liquid film were obtained. The speed of the film increases as the fluid flows through the walls of the evaporator, reaching a maximum on length of 0.075 m. The film thickness decreases on the route, since many compounds are volatilized. The result of the temperature profile had to be consistent with the literature reproduced, being constant after reaching the maximum operating temperature in the length of 0.15 m. This study allowed characterizing and focusing, through experimental analysis, unsaturated compounds and observing the sunflower oil´s behavior through process simulation.

In Brazil many types of bioproducts and agroindustrial waste are generated currently, such as cacashew apple bagasse and coconut husk, for example. The final disposal of these wastes causes serious environmental issues. In this sense, waste lignocellulosic content, as the shell of the coconut is a renewable and abundant raw material in which its use has an increased interest mainly for the 2nd generation ethanol production. The hydrolysis of cellulose to reducing sugars such as glucose and xylose is catalysed by a group of enzymes called cellulases. However, the main bottleneck in the enzymatic hydrolysis of cellulose is the significant deactivation of the enzyme that shows irreversible adsorption mechanism leading to reduction of the cellulose adsorption onto cellulose. Studies have shown that the use of surfactants can modify the surface property of the cellulose therefore minimizing the irreversible binding. The main objective of the present study was to evaluate the influence of chemical and biological surfactants during the hydrolysis of coconut husk which was subjected to two pre-treatment in order to improve the accessibility of the enzymes to the cellulose, removing this way, part of the lignin and hemicellulose present in the structure of the material. The pre-treatments applied to coconut bagasse were: Acid/Alkaline using 0.6M H2SO4 followed by 1M NaOH, and the one with Alkaline Hydrogen Peroxide at a concentration of 7.35% (v/v) and pH 11.5. Both the material no treatment and pretreated were characterized using analysis of diffraction X-ray (XRD), Scanning Electron Microscopy (SEM) and methods established by NREL. The influence of both surfactants, chemical and biological, was used at concentrations below the critical micelle concentration (CMC), and the concentrations equal to the CMC. The application of pre-treatment with coconut residue was efficient for the conversion to glucose, as well as for the production of total reducing sugars, it was possible to observe that the pretreatment fragmented the structure as well as disordered the fibers. Regarding XRD analysis, a significant increase in crystallinity index was observed for pretreated bagasse acid/alkali (51.1%) compared to the no treatment (31.7%), while that for that treated with PHA, the crystallinity index was slightly lower, around 29%. In terms of total reducing sugars it was not possible to observe a significant difference between the hydrolysis carried out without the use of surfactant compared to the addition of Triton and rhamnolipid. However, by observing the conversions achieved during the hydrolysis, it was noted that the best conversion was using the rhamnolipíd for the husk pretreated with acid/alkali, reaching a value of 33%, whereas using Triton the higher conversion was 23.8%. The coconut husk is a residue which can present a high potential to the 2nd generation ethanol production, being the rhamonolipid a very efficient biosurfactant for use as an adjuvant in the enzymatic process in order to act on the material structure reducing its recalcitrance and therefore improving the conditions of access for enzymes to the substrate increasing thus the conversion of cellulose to glucose.

Compete aos agentes que concebem os edifícios, bem como aos legisladores e aos promotores, dotá-los com o máximo possível de tecnologias passivas que permitam ao utilizador economizar, sem no entanto perder conforto nem salubridade. O presente estudo consiste num trabalho de revisão bibliográfica e de investigação experimental com vista à avaliação do comportamento dinâmico de paredes de alvenaria de tijolo térmico. Aferiu-se o desempenho térmico deste tipo de paredes e a viabilidade da sua utilização essencialmente numa perspetiva da redução dos consumos energéticos e de garantia do conforto térmico e salubridade nos edifícios. Os tijolos térmicos estão cada vez mais a ser introduzidos na construção devido ainda à simplicidade na construção e a possível eliminação/redução do material isolante. Neste trabalho construiu-se uma célula de teste com paredes constituídas por este tipo de tijolo, o Bloco ThermoPrélis, cedido pela empresa PRELIS Lda. Assim, mediu-se o desempenho térmico do mesmo em condições reais, em períodos nas estações de primavera e do verão. Os resultados experimentais mostram claramente as vantagens da construção com este tipo de tijolo, que apresenta um atraso térmico de 7 a 8 horas e um amortecimento da amplitude térmica no ambiente interior bastante significativo, tirando partido do mecanismo físico associado à inércia térmica. Em termos de custos, a construção com tijolo térmico apresenta vantagens, quando comparado com a construção típica em parede dupla com isolamento térmico na caixa-de-ar.

O objetivo desta pesquisa é verificar de que maneira os princípios da Construção Enxuta estão sendo empregados em empresa de pequeno porte do segmento de Construção Civil. A pesquisa é de natureza qualitativa e exploratória, sendo o estudo de caso realizado em uma construtora de pequeno porte de edifícios verticais com o apoio do Sindicato das Empresas de Compra, Venda, Locação e Administração de Imóveis Residenciais e Comerciais de São Paulo - SECOVI. Observou-se grande interesse na implantação, sendo um ponto negativo a necessidade de mudança de cultura, visto que muitas atividades tidas como ”vícios” devem ser eliminadas, frente a novo conhecimento. Motivada pelos gestores e alta direção, a filosofia será bem vinda, assim como outras ferramentas de Produção Enxuta, tais como o kanban, housekeeping, 5S, Just in Time e melhorias nos canteiros de obra e processos logísticos. Concluiu-se nesta pesquisa que os princípios da Construção Enxuta são pouco conhecidos pelos profissionais, na prática sendo voltados para gestão da qualidade e produtividade. Constatou-se que, ao mencionar os princípios, estes são de pouco conhecimento, e tem-se uma aceitação imediata quando se fala em redução de tempo e aumento da produtividade com eliminação de tarefas consideradas como de não agregação de valor.

Em Portugal, as iniciativas no âmbito da conciliação trabalho-família e a igualdade entre mulheres e homens têm-se fortificado nos últimos anos. A presente dissertação estuda as “Representações e atitudes sobre igualdade de género dos funcionários e funcionárias de um município português”, tendo partido do desafio de acompanhamento de um processo de planeamento e mudança organizacional - Plano para a igualdade de género - para a eliminação da desigualdade de género numa Câmara do interior centro do país. Analisaram-se os dados de um inquérito por questionário respondido por 206 colaboradores/as da autarquia, dos quais 51,2% são homens e 48,8% mulheres. Com uma escala composta de 34 itens procurámos conhecer a extensão e a expressão dos valores e da estereotipia de género, bem como o reconhecimento da desigualdade e o acolhimento de práticas e políticas igualitárias por parte deste universo. Concluiu-se que ao mesmo tempo que já se admite e se aceita cada vez mais o facto de numa família, os dois cônjuges trabalharem fora e se dedicarem a uma carreira profissional, ainda está presente nas pessoas inquiridas a ideia de que as tarefas vinculadas ao âmbito doméstico são responsabilidades das mulheres, ainda que elas já recebam auxílio dos seus companheiros. Assim, percebemos que embora o mundo público seja cada vez mais ocupado por mulheres, ainda se vincula o espaço “profissional” aos homens e as responsabilidades ligadas ao lar e aos filhos às mulheres. Foi também possível concluir uma forte estereotipia de género que justifica de forma essencialista aquilo que são, na realidade, efeitos da desigualdade de género. Este diagnóstico permitiu desenhar um plano de formação organizacional com enfoque no combate à estereotipia de género e seus efeitos nefastos na gestão das pessoas, na igualdade de oportunidades e no desenvolvimento organizacional. / In Portugal, the initiatives in the scope of the bond work-family and the equity between men and women have been strengthened in the last few years. The present thesis studies the “Representations and attitudes about gender equity between men and women employees of a Portuguese city”, that started with the challenge of overlooking a process of planning and organizational change – Plan for gender equity – in order to eliminate the gender inequity within a City Hall in the interior of the country. Data collected from a questionnaire was analysed. This questionnaire was answered by 206 City Hall employees, of which 51,2% are men and 48,8% are women. With a scale composed of 34 items we sought to understand the extent and the expression of the values and gender stereotyping, as well as the inequity acknowledgement and the reception of equity practices and policies by this universe of people. It is concluded that although, more and more, it is allowed and accepted that in a family both spouses work and dedicate themselves to a professional career, within the people surveyed the idea that the household chores are of the women’s responsibility is still present, the “professional” field is still linked to the men and the responsibilities related to the home and the children are linked to the women. It was also possible to conclude that a strong gender stereotyping justifies, in an essentialist way, what are, in reality, the effects of gender inequity. This diagnosis enabled the design of an organizational training program, with the emphasis on the battle against gender stereotyping and its adverse effects in people management, in equal opportunities between men and women and in the organizational development.
