Full textThis paper results from an exploratory research that describes the practice of selling activity performed by a distribution channel of building paints. The practice of selling activity was depicted by the way it works and by the identification of some attributes that accounts for generation, support and changing of the selling activity. Data were collected from investigating the interaction among the distribution channel agents, represented by a manufacturer ( Killing paints ), and some resellers ( paint stores and building material stores ). The analysis and interpretation of information/data were obtained by comparing the speeches of several distribution channel agents, such as industrial sellers, technicians of paint production and application, managers of stores, retail sellers and painters. Thus, the activities of each type of agents of this distribution channel were identified separately and each agent expressed what had determined his/her selling activity. This account allowed to join both selling activities and attributes which had been repeated by different agents, clearing up how and why the selling activity was played by distribution channel of buildind paints.

Full textBackground: dermatophytes affect 40% of the world population. In Brazil, largest number of patients with HIV/inhabitant occurs in the south, requiring epidemiological control of these fungi. Objective: to determine the prevalence of dermatophytes in the metropolitan area of Porto Alegre, Brazil, and to compare species based on patient data. Methods: we conducted a cross-sectional study with data of patients from a highly respected hospital 1996-2011. The statistical analyses performed for each specific objective were: Simple linear regression (to determine the prevalence of behavior over the years), Chi-square (to compare prevalence of fungi between the genders), Mann-Whitney U (to compare patients' age between the genders), Kruskal-Wallis (to compare the ages of pacients among species of dermatophytes); Chi-square corrected by Bonferroni (to compare ethnic proportion of cases affected by each species with the sample proportion), Fisher's Exact Test / Analysis waste (to determine differences between anatomical sites affected by fungi). In all analyses, = 0.05 was considered. Results: were obtained 14,214 cases mycological culture-positive, being 9,048 cases positive for dermatophytes, making this work the largest epidemiological study of dermatophytosis in the country. Trichophyton rubrum occurred in 59.6% of cases, followed by T. interdigitale (34%), Microsporum canis (2.6%), Epidermophyton floccosum (1.5%), M. gypseum (1.3%), T. tonsurans (0.9%) and T. violaceum (1 case). The slopes of the linear regressions, for T. interdigitale, E. floccosum, T. rubrum and M. canis, were +1.119, +0.211, -0.826 and -0.324% per year, respectively. Males presented higher prevalence of infection (79.3% versus 54.9%), but women were older than men. T. interdigitale and M. canis were most prevalent in Caucasians and T. rubrum was less prevalent in brown people than expected. Tinea unguium was more prevalent of the dermatophytosis (48.5%) being toenails more affected than fingernails (94.4% vs. 4.1%), followed by tinea pedis (33.1%), corporis (6.8%), cruris (5.9%) manuum (2.4%), facie and capitis (1.5% each one) and barbae (0.07%). T. rubrum was the predominant fungus in all regions of the body except in the scalp where M. canis was the responsible for 75% of the cases. The species with the highest positive associations were: T. rubrum (groin); T. interdigitale and E. floccosum (skin of the feet); M. canis and T. tonsurans (scalp); M. gypseum (face). Conclusion: this study corroborates other similar studies in the region related to the distribution of dermatophytes, being T. rubrum the most common species followed by T. interdigitale, and being T. tonsurans the one that presents a very low prevalence, unlike other States. However, this study showed gender differences in relation to age and prevalence of the infection by dermatophytes. Moreover, we observed a decrease in the prevalence of T. rubrum and M. canis and an increase of T. interdigilate and E. floccosum. In this sense, the continuation of epidemiological studies in the region is necessary for monitoring and controlling the evolution of dermatophytosis.

Full textA indústria de têxteis técnicos é uma indústria em crescimento, tendo aumentado a cota dentro do setor têxtil de 5% em 1990 para 28% em 2014 [1]. É espectável que no futuro do setor os têxteis técnicos também incorporem componentes eletrónicos para o desenvolvimento de aplicações especí cas. Desenvolvimentos recentes na indústria da eletrónica exível permitiu abrir novas possibilidades, como células solares exíveis e sensores maleáveis, que podem ser aplicadas no setor têxtil. Neste relatório é discutida a possibilidade da aplicação de condutores exíveis processáveis por solução como resistências de aquecimento. É feita uma revisão das técnicas e métodos de processamento, como as técnicas de processamento em rolo que têm grandes potencialidades em larga escala, e a exploração de diferentes soluções de condutores incluindo o polímero condutor PEDOT:PSS e uma solução de um uoroelast ómero com diferentes aditivos condutores (gra te coloidal e duas partes de uma resina reativa de prata). Foi possível obter aquecimento em camadas de uoroelastómero com gra te como aditivo condutor em três substratos testados, quando foi aplicada uma tensão de +15 V DC. O valor da temperatura em equilíbrio foi atingindo dentro de dois minutos para todos os diferentes substratos. No entanto, o valor de temperatura foi diferente para cada substrato (entre 30oC e 60oC). Este resultado serve de demonstração de prova de conceito para esta aplicação, apesar de ainda ser necessário um grande trabalho de otimização para chegar a aplicações industriais
The technical textile industry is in growth, raising market share within textile industry from approximately 5% in 1990 to 28% in 2014 [1]. Is expected that, in the sectors future, electronic components will be incorporated in textiles in order to develop speci c applications. Recent developments in exible electronics allowed for new devices, like malleable sensors and exible solar cells, that can be applied in the textile sector. In this report, the possibility of application of exible solution processable conductors as heating resistors is discussed. Including a review of processing techniques, such as roll-to-roll, that shows promise in large scale applications, and experimental exploration of di erent solution processable conductors, including the conductive polymer PEDOT: PSS and a solution of uorelastomer with di erent conductive llers (graphite and two parts of silver based conductive epoxy). It was possible to obtain heating on layers of uorelastomer with graphite as conductive ller in all three substrates tested, when applied +15 V DC. The equilibrium temperature was obtained within two minutes for all substrates, although the value of temperature varied with each substrate, ranging between 30oC e 60oC. This result serves as proof of concept for this application, but in order to advance to industrial feasibility is still necessary a great deal of optimisation development.

Full textThe purpose of this study was to contribute to increased knowledge of individuals selfperceptionsthrough the consumption of Tinder. To fulfill the purpose, young individualsexperiences and beliefs about Tinder have been analyzed. The thesis has an inductive and aqualitative approach.The empirical material was collected through semi-structured interviews,and in addition to this, netnographic interviews were conducted. From the empirical work, athematicization was created based on the statements of the informants and three main themeswere devised. The first main theme approached Tinder's different consumption areas,Consuming Tinder, which is important in the analysis, primarily through its explanation factorfor the two following themes; Tinder - dating or hook-up as well as Tinder and self. Theempirical material was analyzed based on social psychological theories of self andconsumption. The thesis contains a number of topics that emerged during the interviews,including the tension whether Tinder is a dating or a hook-up app. This theme was studied onthe basis of several subtitles to ultimately conclude that the consumption of Tinder is havingan impact on young people's self-perception. The study found a number of different waysyoung people consume Tinder and, depending on how Tinder is consumed, differentiate selfperceptionsto expression. Furthermore, the thesis conclude that young people construct aaltered presentation of themselves on Tinder, and there is an awareness that this presentationis not true to reality. Young adults alter their presentations in the hope of achieving morematches, and with this behavior, it appeared to follow an objectification where other userswere more viewed as an object than a person.The thesis is written in Swedish.

Full textA presente dissertação visa compreender a influência dos revestimentos por pintura na secagem de materiais de construção porosos, tendo focado a nível experimental o caso dos substratos constituídos por uma argamassa de cal aérea. Aborda-se, em particular, o caso dos edifícios antigos e, mais especificamente, a situação das paredes com teor de humidade não desprezável que é muito corrente neste tipo de edifícios. O levantamento do estado-da-arte incide sobre as características dos materiais porosos, em particular as argamassas de cal aérea, e de diferentes tipos de revestimentos por pintura indicados para este tipo de utilização. Foca também os mecanismos de transporte de humidade envolvidos nos processos de secagem. Efectuou-se uma pesquisa de mercado e um inquérito ao meio técnico com o objectivo de perceber quais os revestimentos por pintura usados em intervenções de reabilitação / conservação e, assim, avaliar a situação da prática em Portugal. A campanha experimental a seguir realizada incluiu ensaios de permeabilidade ao vapor de água, de absorção capilar e de secagem e incidiu sobre dezasseis revestimentos por pintura disponíveis no mercado português. Treze destes revestimentos são tintas de silicatos, de silicone ou de pliolite que os respectivos fornecedores indicaram serem apropriadas para aplicação em paredes com problemas de humidade. Ensaiaram-se ainda duas tintas de cal de fabrico industrial e uma “tinta plástica” que serviu como referência. A dissertação permitiu obter dados sobre o estado-da-prática em Portugal, em particular no que se refere aos tipos de tintas usados em paredes de edifícios antigos com teor de humidade não desprezável. Permitiu também retirar conclusões sobre: (i) a influência dos revestimentos por pintura na secagem, na absorção de água por capilaridade e na permeabilidade ao vapor de água; (ii) a influência que o estado de humidificação do suporte pode ter no comportamento dos revestimentos; (iii) a correlação existente entre o comportamento à secagem (índice de secagem) e a permeabilidade ao vapor de água, que é a característica correntemente utilizada para prever o desempenho dos revestimentos.

Full textIn tropical countries like Brazil, superficial fungal infections (dermatophytosis) are commonly found. The most common dermatophyte is Trichophyton rubrum (Tr). Mannans and galactomannans of Tr cell wall can suppress cellular responses to the fungus. Regarding the antifungal immune response, the importance of Th17 pathway is warranted. Some C-type lectins (CLRs) as the mannose receptor and / or Toll-like receptors (TLRs) regulate the balance between Th1 and Th17 pathways. Our objectives were to obtain an antigenic extract of Tr to induce cellular immune response; to quantify and classify the immune response of control subjects with mild injury and patients with extensive and / or persistent dermatophytosis caused by Tr, and finally evaluating the expression of CLRs in peripheral blood monocytes in the same groups. Therefore, we produced 11 antigenic extracts of Tr. Proteins with molecular weights of approximately 70 kDa and 38 kDa were evidenced in polyacrylamide gel electrophoresis for the following fungal extracts: extract TCA - Target 1, Tindalized extract G1 and extract Coca 1. We assessed the lymphoproliferative response of mononuclear cells by tritiated thymidine incorporation in the controls and patients, stimulated by YIIDTGIDID peptide fungus Tr (Tri R2) and the antigenic extracts produced in our laboratory. We used as stimuli: PWM, CMA, Tri R2, and PMA/Iono. For functional assays we evaluated four patients and 6 control individuals. For the phenotyping of Th17 cells, Th17MEM, Tc17 and Tc17MEM by flow cytometry, we used a Boolean analysis performed by FlowJo X software. Evaluation of the expression of CLRs: CD206 (mannose receptor), Dectin 1 and Dectin 2 in peripheral blood monocytes from patients and controls was performed by flow cytometry. Of the 11 extracts produced from Tr, seven proved to be able to stimulate proliferation of peripheral blood mononuclear cells of at least one of the analyzed controls, expressed as peak stimulation index (p.m.I.E.). Among them, were included: extract TCA - Target 1 (pmIE = 14.49 at 5 ug /mL), Tindalized G1 Extract (pmIE = 23,00 at 2.5 ug /mL) and extract Coca 1 (pmIE = 173.36 at 0.31 ug /mL). In the evaluation of the expression of receptors of Th17 cells and Tc17 (Th17R and Tc17R, respectively) after six days of stimulation by: Tri R2, Coca extract and the extract TCA 1 - Meta 1, Coca extract showed to be the best stimulator for Th17 populations, with the frequency of 8.40% (control) and 12.30% (patient 1). In the evaluation of the expression of Th17R and Tc17R after 6 hours of stimulation by PMA / Iono, all controls (n = 3) responded and in the group of patients (n = 3) we observed response more frequently for the patient #1, in Th17 populations (1.64%), Th17MEM (3.27%), Tc17 cells (10.70%) and Tc17MEM (3.58%). We observed a reduction of expression of CLRs in patients: CD206: average 60.24% (controls) and 21.27% (patients), Dectin 1: 22.42% (controls) and 12.06% (patients) and Dectin2: 26% (controls) and 4.99% (patients). Controls (n = 6) and patients (n = 3). Innovation in the production of antigenic extract extract TCA - Target 1 encourages the study of fungal extracts to obtain better conditions of evaluation of the immune response in patients with dermatophytosis. We characterized and qualified the cellular immune response to the TriR2 peptide, to antigen extracts, and evaluated the expression of CLRs in this special group of patients

Full textThe purpose of this study was to contribute an understanding of how users of the application Tinder present themselves, compared to how they consume and evaluate others profiles. The study addresses whether consumption culture and social structures affect consumers' use of Tinder and how it shows through their consumption. The study has been conducted through a qualitative approach based on three focus group discussions. The main focus has been on how and why people use the online dating application Tinder. The empirical material has been analyzed by using theories of consumption culture from a social psychological perspective. The research questions aims to study the needs and purpose of consumers linked to the application, which has resulted in the following questions: What does the consumers wish to fulfill through its consumption of Tinder?, How do consumers present themselves through their profiles on Tinder? and How does the user consume others profiles on the application? The result of the study shows that young adults consume the application when they wish to escape everyday life. Consumption contributes to an estimation of the consumers own value and results in the consumers self-realization with the application as a tool. Tinder provides the outlet for imagination that creates value for the consumer when constructing his own profile or when consuming others profiles. The thesis is written in Swedish.

Full textUma tinta para fachadas tem como principal função impedir a entrada de água através da superfície exposta. É igualmente importante que a tinta apresente um comportamento suficientemente elástico para acompanhar as alterações no substrato, provocadas pela temperatura e pela humidade. A resina, ligante, é o componente mais importante da tinta e assume um papel crucial nas propriedades desta. Perante isto, desenvolveu-se o presente estudo em cooperação com o Departamento de I&D da CIN – Corporação Industrial do Norte, S.A, tendo como principal objetivo o estudo da incorporação de resinas alternativas em tintas decorativas. Neste trabalho foi estudada a substituição da resina presente em diferentes tintas, por duas resinas, a resina A e a resina B, e efetuados os ensaios comparativamente à tinta padrão. Numa primeira fase as formulações de tinta foram caracterizadas seguindo uma lista de ensaios típicos para uma tinta de exterior dos quais se destacam pela sua importância na caracterização deste tipo de tinta, a medida da viscosidade, o teste de resistência às cinzas, o índice de brancura e de amarelecimento e a fissuração Mudcraking, entre outros. Posteriormente foram enviadas amostras de tinta para um laboratório externo para a realização de ensaios complementares como a absorção de água cíclica e ensaios mecânicos para a determinação do alongamento à rutura e resistência à tração. Finalmente foram efetuados ensaios de envelhecimento acelerado e envelhecimento natural que, por terem um período de exposição mais longo, requerem mais tempo para uma decisão final. A análise dos resultados obtidos permite, numa primeira abordagem, concluir que a resina A é aquela que permite obter tintas com características muito semelhantes às das tintas padrão. Esta conclusão terá que ser reavaliada após conhecimento dos resultados dos ensaios de envelhecimento natural.
The main function of a paint for facades is to prevent water from entering through the exposed surface. It is also important that the paint is sufficiently elastic to track changes in the substratum caused by temperature and humidity. The resin, binder, is the most important component of the paint and plays a crucial role in its properties. Thus, the present study was developed in cooperation with the R&D Department at CIN – Corporação Industrial do Norte, S.A, having as main objective the study of the incorporation of alternative resins in decorative paints. In this work the replacement of the resin present in different paints, for two resins, A and B, was studied, and tests were performed for comparison to the standard paint. In a first stage the paint formulations were characterized following a number of routine tests for an outdoor paint, namely, the viscosity measurement, the dirt pick-up resistance, the rate of whiteness and yellowness and the Mudcracking, among others. Afterwards paint samples were sent to an external laboratory to carry on further tests, namely regarding the water cycling absorption and the elongation at rupture and tensile strength. Finally accelerated aging and natural aging tests were performed. These tests require larger exposure periods and therefore more time for a final decision is needed. The analysis of the results allows to conclude that, on a first approach, the resin A yields paints with characteristics very similar to the standard paints. This conclusion will have to be re-evaluated after knowing the results of natural aging tests.

Este trabalho tem a intenção de estudar uma das figuras mais importantes do imaginário Ocidental, o Diabo, tal como este se apresenta pelas tintas do escritor, Joaquim Maria Machado de Assis. Para tanto, nos propomos realizar uma leitura dos seguintes contos de Machado: “Adão e Eva”, “A igreja do Diabo” e o “Sermão do Diabo”, nos quais o Diabo comparece explícito como personagem, e assim, evidenciaremos de que forma ele foi apropriado pela literatura machadiana. Em “Adão e Eva” procuraremos mostrar de que modo Machado de Assis reinterpreta o papel do Diabo na criação da humanidade. No conto “A igreja do Diabo”, tentaremos delinear de que maneira o escritor, a partir da figura do Diabo, critica as instituições religiosas. E por fim, no conto “O sermão do Diabo”, a proposta é mostrar que Machado de Assis, através do personagem Diabo, constrói uma irônica crítica à sociedade do século XIX, que vendeu sua alma ao diabólico capital.
This dissertation aims to study one of the most important entities of the Western imagination, the Devil, such as it is presented in the works of the writer Joaquim Maria Machado de Assis. For this purpose, we set to perform a reading of the following stories: “Adão e Eva”, “A igreja do Diabo” and “O sermão do Diabo”, in which the Devil appears explicitly as a character, and thus we shall make clear the way in which it has been appropriated by Machadian literature. In “Adão e Eva” we shall demonstrate how Machado de Assis has reinterpreted the Devil’s role in the creation of humankind. In the story “A igreja do Diabo” we shall delineate how the author, through the Devil as a character, criticizes religious institutions. Finally, in the story “O sermão do Diabo”, our purpose is to demonstrate that Machado de Assis, through the Devil as a character, proposes an ironical criticism of nineteenth century society, which had sold its soul to diabolic capital.

Full textThis thesis is a study of the artistic and architectural production of the Jesuit Missions in the former State of Maranhão and Grão Pará, which was established in 1621, with a special emphasis on the Captaincy of Grão Pará. The period under study spans the time from 1653, when the Society of Jesus settled in the city of Belém, to 1759, when the Jesuits were expelled from Portuguese colonies. This thesis focuses in particular on the artistic work of both jesuits and indians carried out in the workshops at the Jesuit School of Santo Alexandre in Belém in the 18th century. The thesis seeks to trace the dissemination of the models created in such workshops throughout the Jesuit churches and chapels that were built along the borders of the River Amazon and its tributaries, especially those located in the Jesuit aldeias, vilas and fazendas closer to Belém (Vila de Nossa Senhora de Nazaré da Vigia, Vila Souza do Caeté, Mortigura, Gibirié, Mamaiacú, Jaguarari, among others). The hypothesis under investigation in this study is that Belém, in addition to being an economic and commercial hub, was also an artistic center providing models, working methods and technical expertise for the entire Jesuit artistic community in the Grão Pará. The title Tintas da Terra, Tintas do Reino summarizes the core idea underlying this thesis, namely that the Jesuit legacy in the art and architecture of the Grão Pará missions is the result of the work of europeans and indians, who in doing so resorted to their respective cultural traditions.

Há cerca de trinta anos, falar sobre a inclusão de estudantes cegos em classes regulares de ensino era utopia. Atualmente, todo o sistema de ensino enfrenta dificuldades, entre elas: a preparação de professores (MACHADO, 2009) e o aumento do número de matrículas de estudantes com necessidades educativas especiais em escolas públicas regulares (BRASIL, 2001a). Mesmo assim, a inclusão saiu do âmbito da discussão e virou um fato e um direito de estudantes cegos. A presente pesquisa  de caráter qualitativo - conta com a experiência de uma professora em sala inclusiva com estudantes cegos do 9º ano do ensino fundamental que constatou a necessidade de análise de dois documentos utilizados para ensinar: o Código Matemático Unificado para a Língua Portuguesa  CMU e o Livro Didático transcrito para o Braille (LDB). No CMU foi analisada a coerência matemática em relação à simbologia. Já no LDB, foi analisada a conformidade em relação ao CMU e ao que é apresentado no livro didático em tinta (LDT). Tanto no CMU como no LDB buscou-se verificar a existência do fenômeno da não-congruência semântica em Duval (2003, 2004, 2011) e as suas influências para o estudante cego e para o professor. Concluindo tal análise, foram apontados equívocos em relação à coerência matemática do CMU e verificou-se a instalação do fenômeno da não-congruência semântica tanto no CMU como no LDB. A instalação da não-congruência semântica mostrou possíveis pontos geradores de dificuldades para o estudante cego (quantidade aumentada de caracteres, tempo de resolução de questões, leitura e interpretação de imagens prejudicadas) e para o seu professor (sanar dúvidas e conhecimento do Sistema Braille). A autora indica a necessidade de uma revisão no CMU, mostrando outros pontos a serem analisados além dos já mostrados na pesquisa, como: conteúdos de ensino médio e superior e ainda, a organização do conteúdo do Código em si. Constatou-se a necessidade do aprendizado do Braille pelo professor já indicada por Machado (2009) e Masini (2013), o que possibilitou a reflexão sobre as características necessárias ao desenrolar da educação inclusiva: a coragem e a persistência.
Abstract : About thirty years ago, to talk about the inclusion of blind students in regular classes was a utopia. Nowadays, the whole education system faces difficulties such as teacher training (MACHADO, 2009) and the increased number of enrollement of students with special educational needs in regular public schools (BRASIL, 2001a). Nevertheless, the inclusion has gone beyond the scope of a discussion and become the fact and the rights of blind students. This present research - qualitative in nature - reports the experience of a teacher in an inclusive classroom with blind students from 9th grade of primary school where she found the need to analyze two documents used for teaching: the Unified Mathematical Code for the Portuguese language  CMU and the textbook transcribed into Braille (LDB). Mathematical consistency in relation to symbolism was analyzed in the CMU. As for the LDB, its compliance with the CMU and with material presented in ink print textbooks (LDT) was examined. In both the CMU and the LDB it was sought to verify the existence of the phenomenon of semantic noncongruence as in Duval (2003, 2004, 2011) and the influences of these two documents for the blind student and the teacher. Concluding that analysis, some misconceptions were pointed out regarding mathematical consistency of the CMU and the phenomenon of semantic noncongruence was found in both the CMU and the LDB. The existence of semantic non-congruence demonstrated potential sources of difficulties for the blind student (increased number of characters, time for problem solving, impaired reading and interpretation of images) and for the teacher (solving doubts and knowledge of the Braille System). The author emphasizes the need of the CMU revision showing other issues to be analyzed beyond those shown in the research such as the content standards in the Middle and High School and also the organization of the CMU content. There has been found the need for the teacher to learn the Braille System as already pointed by Machado (2009) and Masini (2013), and that allowed to reflect upon the characteristics required to improve inclusive education: courage and persistence.

Neste trabalho, analiso a emergência do sujeito travesti em Fortaleza (CE), seu surgimento como nova personagem público-midiatizada e estigmatizada, na passagem do tempo das perucas para o tempo dos hormônios, este último, chamado de tempo farmacopornográfico (virada da década de 1970 para 1980). Problematizo esse processo de subjetivação farmacopornográfico a partir de uma análise foucaultiana e de gênero-queer das fontes históricas (jornais, revistas, obras literárias, antropológicas e narrativas orais de travestis). Se, no tempo das perucas, o termo travesti designava uma prática eventual, restrita aos espaços privado e/ou público-temporário, no tempo farmacopornográfico, a palavra também passou a nominar um novo sujeito sexual, que ganhou inteligibilidade heteronormativa, em grande parte, graças aos meios de comunicação, como um "tipo" de homossexual marcado pela ambiguidade. Tal emergência foi acompanhada por discursos e práticas de excitação-fascÃnio e de controle-estigma. Nessa trama-tempo marcada por embates, as travestis produziram contra-discursos que contribuÃram para rearranjar as normas de gênero, sexualidade, corpo e do público-privado em Fortaleza.
Abstract : In this paper I analyze the emergence of the subject transvestite in Fortaleza (Ceará State), its appearance as a new public-mediatized and stigmatized character in the passage of the wigs times to the hormones-pharmacopornographic times (in the turn of the 1970s to 1980s). I problematize this process of pharmacopornographic subjectivity from a Foucault's analysis of gender-queer of historical sources (newspapers, magazines, literary, anthropological and oral narratives of transvestites). If, at the wigs times, the term transvestite designated an eventual practice, confined to private spaces and/or public-temporary ones, at the pharmacopornographic times the word also came to nominate a new sexual individual who got heteronormative intelligibility, largely by the media, as a "type" of homosexual marked by ambiguity. Such emergence was accompanied by speeches and practices of excitation-fascination and control-stigma. At this plot-time marked by clashes, transvestites produced counter-speeches that contributed to rearrange gender norms, sexuality, body, and public-private in Fortaleza.

Full textInternet dating has, since the 1990s, become increasingly popular and has in recent years moved from websites to apps in smartphones that streamline the process of meeting other individuals. One of these apps is Tinder, which revolutionized internet dating through its peculiar way to match users. Although the app is very popular it seems that it is not fully acceptable to use it. The use of the app has been compared to similar embarrassment identified in research on Internet dating sites. The purpose of this paper is to examine how Tinder-users normalize their use and the strategies they use to normalize it, and to understand the relationship between embarrassment and normalization. The study is based on semistructured interviews conducted with 10 students at Uppsala University who actively used Tinder. The theoretical framework is based on a number of key concepts, labeling theory, social norms, soft and hard stigma, normalization, normification and strategies to avoid the stigma. Tinder is normalized among its users. But even tho the app is considered normal the users still have to behave in a certain way when they use the app. It is a normalization within certain limits. They use strategies to avoid the embarrassment associated with so-called hookup culture or the perception of users as desperate in the search for a more "serious" relationship. The declared normalization and the perceived embarrassment associated with soft stigma are managed using various strategies and seem to take different forms depending on what embarrassment is based in. Previous research has shown that internet dating is linked to stigma, but that stigma has diminished in power over the last 20 years. However, previous research has not highlighted the normalization processes and the strategies that appear to normalize the internet dating and manage the stigma. The strategies identified in the material for this thesis appeared in previous research, except for the strategy “renouncement of personal commitment”. We believe that Tinder-users adapt education as a strategy to normalize its use and stresses usage as something quite normal. Other strategies were used to normify use. To normify means to construct an action or behavior so that it falls within the boundaries of what is socially acceptable.

Coordenação de Aperfeiçoamento de Pessoal de Nível Superior
Neste trabalho foram desenvolvidos processos de produção de tintas para a construção civil que utilizam os solos como fonte de pigmentos, na perspectiva da criação de uma tecnologia social. Foram coletados três solos representativos das cores e ocorrência no município de Viçosa-MG. O disco Cowles foi aperfeiçoado e usado para dispersar as partículas dos solos e selecionar as de menores tamanhos (< 0,18 mm). A estabilidade das suspensões de pigmentos foi avaliada na presença e ausência de dispersante químico. Por meio do delineamento experimental de misturas, foram produzidas misturas ternárias e quaternárias, cada qual utilizando um tipo de resina. O desempenho das misturas foi avaliado quanto aos poderes de cobertura seco e úmido e à resistência à abrasão, de acordo com os limites estabelecidos pela ABNT para tintas látex da categoria econômica. A viscosidade e o pH foram medidos e relacionados ao desempenho das misturas. Os resultados obtidos indicaram que em nenhuma das misturas foi possível obter formulações que atendessem a todos os requisitos de desempenho simultaneamente, e que as misturas quaternárias proporcionaram os melhores resultados. O pH exerceu forte influência sobre o desempenho das tintas, no que se refere à viscosidade, à resistência à abrasão e aos poderes de cobertura. As misturas quaternárias e a dispersão mecânica mostraram-se como alternativas promissoras para a adoção como tecnologia social.
This work developed production processes of paint for building using soils as pigment source, aiming at designing a social technology. It was collected three soils with typical colours and availability within the Viçosa –MG city. The Cowles disc was improved and used to disperse soil to select particles (< 0,18 mm) as soil pigment sources. The suspension stability of pigments was improved with and without chemical dispersants. It was used a mixture experimental design method to define three groups of samples, each one with pigments of the collected soils, according to two methods, both with water as a solvent. The Method 1 used poly vinyl acetate as a resin and the Method 2 used polyvinyl alcohol. The performance of the mixtures were evaluated for the dry/wet covering power as well for the abrasion resistance, according to the thresholds assumed for latex paints of economic class defined by the Brazilian normalization agency (ABNT). The viscosity and the pH of the mixtures were determined and related to the performance of the mixtures. The results indicated that none of the series fulfilled simultaneously all requirements of the ABNT norms and that Method 2 produced the best set of results. The pH was highly related to the performance of the paints, controlling viscosity, resistance to abrasion and dry/wet covering power. The Method 2 and the mechanical dispersion emerged as promising alternatives to be adopted as social technologies.

Full textThis work presents the results of the determination, using ICP OES, of the toxic and/or potentially toxic elements (AI, Cr, Ni, Cu, Cd, As, Co and Pb) in paints based in water or organic solvent. Sample digestion method were developed and compared using different acid mixtures in decomposition pumps, in microwave oven (focused and with cavity) and ash method. The digestion method using microwave oven with cavity allowed fast and efficient solubilization of ali tested types of paints, in inferior time to 35 mino The methodologies showed acceptable values for the majority of the elements using addition and recovery tests. The residues resulting of the digestion were analyzed by SEM-EDS and did not present the studied elements, checking the efficiency of the method. Mercury was determined using a Direct Mercury Analyzer (DMA) presenting values between 43.0 ± 4.5 and 188 ± 9 µg.kg-1, value considered low when compared to the Iimit of 100 mg.kg-1, established in the norm NBR 10004 for disposition of solid residues without special installations. The migration of the elements for the environment was studied afier the exposition of the paints to aggressor agents, Iike ultraviolet radiation and humidity, using a Weather-Ometer type chamber (accelerated aging). The evaluation of the results was performed by SEM-EDS and ICP-OES. The SEM micrographs showed changes on the polymer morphologies submitted to accelerated aging. The obtained results were not conclusive on the migration of elements because of the low mass ratio between the degraded and non-degraded samples. The proposed method for the evaluation by ICP-OES of paints and the disponibility of toxic and potentially toxic elements, based on the lixiviation of dry samples in controlled environment is described. Lixiviation results of AI, Cr, Ni, Cu, Cd, As, Co and Pb using several different removal agents and extraction times are presented. The results show that happens the migration of some elements for the studied solutions and that, among ali removal agents, the acid rain showed the highest lixiviation potential. that, among ali removal agents, the acid rain showed the highest lixiviation potential.

Full textQuaternary ammonium compounds are widely used as antiseptic agents, disinfectants, detergents and preservatives. In addition, quaternary ammonium compounds are often used as algaecides, and dodecyl dimethyl benzyl ammonium chloride (benzalkonium chloride) is the most effective against these microorganisms. However benzalkonium chloride is not used as surface algaecide compound due its high hydrophilic, bring on high leaching of this compound when the surface is exposed to high humidity and severe weather from tropical climate. Currently, compounds such as diuron and s-triazine are used as microbial agent, considered low leaching. However diuron and s-triazine were detected in coastal regions in high levels concentration showing the leaching of these biocides when used in antifouling paints in ships. Considering these, it can be observed the necessity to develop a new algaecide to overcome the failings of leaching of the compounds used nowadays. Material as organoclay is an excellent alternative because they are highly hydrophobic. Therefore in this work was synthesized a new nanomaterial using benzalkonium chloride, which was applied in a house paint formulation. The material was characterized by the techniques of X-ray diffraction and thermogravimetric analysis. A film coating was placed in a leaching chamber, simulating the action of rain. After leaching the coating film was applied to microbiological tests to check if the surface still had microbial protection against the following algae species: Phormidium cebenense, Trentepohlia odorata, Chlorella sp and Scenedesmus quadricauda; placed in a pool of algae. It was possible to determine the structure and quantify the amount of benzalkonium chloride in the material through X-ray Diffraction and Thermogravimetric analysis, respectively. The biocide capabilities as well as the resistance to weathering of coating with the material were analyzed by microbiological and leaching test, respectively. The new compound developed in this study has a high potential to be used as microbial agent in paints.

Nesta dissertação, foram estudadas as propriedades elétricas de compósitos de negro de fumo/tinta a base de polivinil (NF/PV) e negro de fumo/tinta a base de poliuretana (NF/PU). Em ambos, as tintas foram utilizadas como matriz e o negro de fumo como material condutor. Os compósitos foram preparados com quantidades fixas de tinta e diferentes concentrações de negro de fumo. Medidas de corrente continua (dc) das diferentes amostras permitiram a construção da curva I-V, da qual se obteve o valor da resistência elétrica. Através da análise dos gráficos de resistividade em função das diferentes concentrações de material condutor foi possível notar para essas amostras o comportamento característico dos sistemas percolativos. Foi observado um limiar de percolação da ordem de 1,04 % em massa de negro de fumo para o compósito NF/PV, e da ordem de 2,84 % em massa de negro de fumo para o compósito NF/PU à temperatura ambiente. Foram feitas medidas dc da resistividade para a faixa de temperatura de 310 K a 4 K em um criostato em circuito aberto e do tipo de gás de troca. Com esses dados construiu-se o gráfico da energia de ativação diferencial (EAD) em função da temperatura (T), o que permitiu identificar a ocorrência do mecanismo de transporte por saltos (hopping) de alcance variável em três dimensões em todas as amostras. Aumentando concentração de negro de fumo a resistividade elétrica diminuiu conforme esperado.

Este estudo tem como objetivo principal problematizar a relação entre os conhecimentos escolares sistematizados, as práticas avaliativas desenvolvidas na sala de aula de espanhol como língua adicional e as práticas sociais cotidianas dos alunos surdos. Para buscar atingir esse objetivo identifico, descrevo, analiso e interpreto rotinas do trabalho pedagógico de uma sala de aula de Espanhol em uma turma inclusiva de 6º ano com sete alunos surdos e onze alunos ouvintes, de uma escola pólo no ensino de surdos, da rede básica de ensino do município de São José. Embora o foco da investigação tenha se voltado mais para a turma inclusiva, também foram realizadas observações em uma turma bilíngue do 1º ano do ensino médio, sobre a qual discuto algumas práticas de linguagem e usos do espanhol como língua adicional, realizadas por alunos desse grupo, relevantes para esse estudo. Situada na área de Linguística Aplicada, essa pesquisa foi desenvolvida a partir de uma perspectiva etnográfica, interpretativista e consiste, especialmente, de registro de dados através da observação sistemática da rotina escolar do grupo de dezoito alunos da turma inclusiva, que conta com uma professora que domina três idiomas: português, espanhol e LIBRAS e com uma intérprete de língua de sinais durante todo o período de aulas. Além disso, consiste de observações da turma bilíngue, de análise documental e de entrevistas com participantes da comunidade escolar. A referência teórica que sustenta este trabalho nos conduz a repensar a prática avaliativa do ensino da língua adicional sob uma perspectiva pós-colonialista (Pennycook, 1998, 2010; Rajagopalan, 2003; Garcez, 2013; Lucena, 2006, 2010; García, 2009; Schlatter & Garcez, 2009; 2012; entre outros). Durante a análise e interpretação dos dados, aponto para discussões que possam contribuir com o processo de ensino-aprendizagem do espanhol desse alunado e para práticas avaliativas que contemplem as características desse grupo minoritarizado. Os dados revelam que apesar do empenho de professores e da intérprete no processo de ensino-aprendizagem e da inclusão dos alunos surdos na aula de espanhol, a maior parte das avaliações realizadas não é significativa e tampouco se mostra produtiva, contribuindo pouco com a aprendizagem desses alunos. Nesse sentido, esse estudo aponta o descompasso existente entre a teoria que rege a avaliação no ensino de língua adicional (espanhol) no contexto dessa sala de aula inclusiva e sua prática em si. Através dos registros pode-se também identificar a necessidade explícita dos alunos surdos por práticas de avaliação mais coerentes com o uso da linguagem em suas realidades, de modo que elasforneçam elementos que possam contribuir para avaliar, efetivamente, o desempenho do aluno no idioma espanhol. Os resultados dessa pesquisa contribuem para a literatura sobre avaliação em língua adicional no contexto de línguas minoritarizadas, principalmente no que diz respeito a comunidade surda.
Abstract : The main objective of this study is to problematize the relation among systematized school knowledge, assessment practices developed in the Spanish as an additional language classroom and everyday social practices of deaf students. In order to achieve this goal I identify, describe, analyze and interpret the teaching routines in a Spanish classroom in a sixth-grade inclusive group with seven deaf students and eleven hearing students, of a core municipal school on the education of the deaf, in São José. Although the focus of the investigation has been on the inclusive class, a bilingual first-year high school class was also observed, and I discuss some language practices and Spanish as additional language usages performed by students of this group which are relevant to this study. Under the theoretical assumptions of Applied Linguistics, this research was developed from an ethnographic interpretive perspective and consists especially of data recording through systematic observation of the school routine of the eighteen students group in the inclusive class, which has a teacher who mastered three languages: Portuguese, Spanish and LIBRAS and a sign language interpreter throughout the class. Besides, this research consists of observations of bilingual classes, documental analysis and interviews with participants of the school community. The theoretical framework that underpins this research leads us to rethink the evaluation practice of additional language teaching in a post colonialist perspective (Pennycook, 1998, 2010; Rajagopalan, 2003; Garcez, 2013; Lucena, 2006, 2010; García, 2009; Schlatter & Garcez, 2009, 2012, among others). During data analysis and interpretation, I point out discussions that may contribute to the Spanish teaching and learning process of these students and to evaluation practices that consider the characteristics of this minority group. The data reveal that despite the efforts of teachers and interpreters in the teaching-learning process and of the inclusion of deaf students in Spanish class, most of the evaluations is not significant nor shown productive, with few contribution to these students learning. Thus, this study highlights the mismatch between the theory that supports the assessement in the additional language (Spanish) teaching in the context of this inclusive classroom and its practice. Through the registers, it was also possible to identify deaf students? explicit need of assessment practices which are more coherent with the use of language in their reality, so that theyprovide elements that can contribute to effectively assess the student performance in the Spanish language. The results of this study contribute to the literature on assessment in additional language in the context of minority languages, especially with regard to the deaf community.

Full textThe main purpose of this study was to investigate the effect of reflective colored paints and conventional colored paints applied on fiber cement corrugated roofing sheets, proving whether both type of paints can present different reflection characteristics in the infrared solar radiation and high thermal performance. Color and gloss were measured by instrumental methods and reflectivity (reflection coefficient) was measured using spectrophotometers equipped with integrating spheres in free paint films. In order to investigate the thermal performance of reflective and conventional paints, simulation tests were performed in laboratory by IR lamps using fiber cement specimens and in field by exposure solar radiation using prototypes with temperature monitoring. The results showed that the reflective paints present higher reflectivity and better thermal performance than the conventional paint, independently of the color. The results showed that the reflective paints present potential to reduce superficial temperature of fiber cement corrugated roofing sheets. It is necessary to continue the reflective colored paints study on durability and thermal performance by exposure tests.

Full textThe dermatophytes are between the more spread and prevalent diseases caused by fungi, they affect millions of people all over the world. Tinea capitis is the most common fungal infection in the pediatric age, it is contagious, having an increasing risk of infection when there is sharing of objects and few hygiene cares. It’s an infection that affects essentially children and pre-teenagers, being also these ones who present more susceptibility and exposure to the infection. It’s an infection with worldwide distribution, being more common in Africa. Previously the endemic areas were more define, but with the increasing of inter-continental travel and immigration new diseases have been expanded in the host countries, therefrom the increasing prevalence of this infection in the European countries. Apart from being a disease with a marked social impact, that takes children to the restriction of social activities, such as going to school and all the ensuing consequences, such as exclusion. Faced with this situation, a study was realized to identify the occurrence of tinea capitis in children with ages among 1-14 in Santa Filomena’s neighborhood, county of Amadora, Portugal, and the knowledge (definition, diagnosis and treatment) of parents/responsible for the children about the disease, in order to draw the strategies of intervention. The population was composed by 127 children, attending to the Amigos of Encosta Nascente Association and Catechism Center taught in Santa Filomena’s neighborhood, being 44,9% male and 55,1% female, with ages among preschool and school. Three techniques of diagnose were used, clinical observation, microscopy and culture exam. The samples of the children scalp were analyzed in the Mycology Laboratory of the Institute of Hygiene and Tropical Medicine, Lisbon. The prevalence of children with active disease were 17,3% and 19,7% carrier. Two etymological agents were identified, Microsporum audouinii and Trichophyton soudanense (fungi of African origin). To the parents and responsible for the children was applied a questionnaire about related aspect with the infection of tinea capitis. The answerers showed few knowledge, some until incorrect. In order to control the infection, is necessary involve several partners, as Health Centers, Education Centers (nurseries/schools/catechism) and parents/responsible for the children, intervening in their education with educational sessions, screening, diagnosis, treatment, preventive actions and improvement of personal and environment hygiene.

Analisar experiências singulares, juvenis e independentes de mulheres em Teresina-PI, na década de 1980, constitui a intenção desse estudo. O principal argumento organiza-se sobre a ideia de que, por essa época, os discursos propagados em jornais, revistas femininas e pela TV buscavam oferecer parâmetros culturais que favorecessem, por um lado, o rompimento com uma mentalidade patriarcal, ainda, fortemente marcada por valores morais católicos e, por outro, o surgimento de novas práticas sociais de determinado modelo de mulheres, que ousaram criar novos formatos de sonhos, iniciativas e independências em Teresina. Observou-se que esses fatores redefiniram as identidades ditas femininas, desdobrando-as noutros modelos e performances, modificando as práticas familiares e da conjugalidade. Nesse sentido, novos signos e símbolos foram definidos na arte, cultura, política e no espaço urbano, com a abertura de novas oportunidades de empregos, estudos e de entretenimento, bem como novas possibilidades de cidadania às mulheres jovens, que sonhavam com sua independência financeira, profissional e familiar. Por esse caminho e com base na análise das trajetórias de sete mulheres que vivenciaram sua fase juvenil em Teresina, observou-se que a travessia dos anos 1980 foi impulsionada por mudanças que, embora iniciadas nos anos 1960 e 1970, foram propagadas pelos canais de mídia, representados pelas FMs e por jornais impressos, a exemplo do Jornal O Dia e Estado, trajetórias que deveriam atender às expectativas de performances de mulheres que acompanhassem o ritmo veloz dos anos 1980. Nesse cenário observou-se também uma energia transformadora do sujeito mulher, com a legitimação de condições para constituir-se mulher independente dos valores impostos pelos resquícios do patriarcalismo na sociedade piauiense. A pesquisa foi alicerçada nas leituras que problematizam na pesquisa historiográfica, o campo dos estudos de gênero, seguindo pela ótica da nova história cultural o diálogo com Vaitsman (1994), Cardoso (2003), Castelo Branco (2013), Queiroz (2006), Pinsky (2013), Pedro (2013), Perrot (2016), Rolnik (2014), Certeau (2011), Foucault (2012), entre outros autores, as ideias de identidades culturais, experiências femininas e as mudanças nas práticas familiares e na conjugalidade no final do século XX.
An analysis about the youth singular, behavior and independent experience from women in Teresina-PI in the 80’s is the intention of this research. The main argument is organized surrounding the idea that, around in the 80’s media speech, such as newspaper, women´s magazine and TV shows, aimed to offer cultural standards which could be inclinable to break up with a patriarchal mentality, still strongly marked with Catholic’s issues and, on the other hand, new social practices changing women conduct, whom dared themselves to create new ways to dream, experience and get independent in Teresina. This research reveals that these factors redefined identities known as for women, highlighting other roles able to modify family experiences and perceptions in wedding issues. In this sense, new signs are defined in arts, culture, politics, urban space, providing more opportunities in jobs, studies and entertainment, and also new citizenship possibilities to young women which dreamed about financial, professional and familiar independency. In this way, based on Orality, in the analysis of the narratives of 07 women who has spent their youth in Teresina. It was observed that throught the 80’s the behavior was influenced by changes made in the 60’s and 70’s by media, channels, represented by radios and press newspapers, such a O Dia e Estado had disseminated patterns to reach the female model accepted in those quickly 80’s. On that reality was also observed a huge change in women´s lives, giving them conditions to be independent of the patriarchal values still observed in Piauí society. The theoretical research was based on Authors who discuss in the field of historiographic research, gender studies under new history point of view, such as Vaitsman (1994), Cardoso (2003), Castelo Branco (2013), Queiroz (2006), Pinsky (2013), Pedro (2013), Perrot (2016), Rolnik (2014), Certeau (2011), Foucault (2012) and others, with cultural identity ideas, women’s experiences, and changes in familiar and marriage models in the end of the 20ᵗʰ century.

Full textThis report aims to examine how the design and usage of the mobile dating application Tinder has affected behaviors and norms regarding online dating amongst young adults in Sweden. One main purpose is to examine how different interaction mechanisms in Tinder affects the view of online dating and potential partners. Additionally factors that differentiate Tinder from other online dating services will be examined. Furthermore social norms that are made visible through the usage of Tinder will be addressed. By creating an online survey it was possible to retrieve user experiences of Tinder usage and opinions about Tinder and online dating. Based on material from the survey three focus group interviews were conducted, which gathered different perspectives young adults had regarding online dating and Tinder. The conclusion will be presented by analyzing the data from the informants combined with theories such as User Experience, affordances, design qualities, self representation, gamification and market metaphors. Several mechanism associated with gamification were found in Tinder regarding design and user behavior. The Tinder users in general also seem to reproduce current gender norms in an otherwise neutral and minimalistic design. Furthermore market metaphors were found regarding online dating in Tinder. Additionally Tinder seems to target a new group of users in online dating, accordingly considered as ”laid-back” and equal to other social media. The connection to Facebook also contributes to an increased trust towards the self representation of Tinder users. Finally the swipe centered “yes-or-no-functionality” of Tinder seems to create a standard that will affect future dating services and User Experience.

Full textThe dating market for young people today can be through a physical meeting out at the pub just as well as through a spontaneous "liking" via an app. We humans develop methods to present ourselves in the most attractive way to potential partners, whether it is about editing an image or standing in front of the mirror for hours. Over time, developments within the dating market have made it easier for interaction with others, from newspaper ads to online dating sites to one of today's most popular mobile dating app Tinder. The purpose of this paper is to study Swedish youths´ perception of the dating app Tinder from two perspectives. On the one hand, their perceptions of Tinder's possibilities and limitations in general in finding a partner and on the other hand, their perceptions of their own and others' selfrepresentations. To answer the purpose, a qualitative method has been used with semistructured interviews as the collection method for the empirical material. Six interviewees make up the sample in the study, three men and three women, all of whom are aged 20-25 with experience of dating via Tinder. The analysis of the material was conducted from a gender perspective mainly where the used theories were social constructionism and poststructural feminism. The results of the study show that Tinder as a dating resource is experienced as an app with enormous simplicity where the negative aspect is the fear that the individuals behind the profiles should not be who they claim to be. The results also showed that the male interviewees link self-representation of female users to an identity based on how Tinder constructs the gender within the “community” Tinder where the meeting is a restart as the initial contact is mainly about the physical attraction rather than the psychological. The female users, on the other hand, saw self-representation as a way of initially appearing more self-confident and the physical relationship creates a prerequisite for the psychical one. This result also developed into an identification of a power relationship between the male and female interviewees where there is an interaction on Tinder between having power over and having power to which shows how power relations on Tinder are both created and transformed.

Full textWaterborne acrylic resins suitable for anticorrosive coatings were obtained by miniemulsion polymerization of methyl methacrylate (MAM), butyl acrylate (AB) and acrylic acid (AA) using a hydrocarbon resin (RHC) as osmotic agent. Miniemulsion polymerization is powerful technique that allows the incorporation of preformed solventborne polymers in a waterbased matrix. It consists of small, stable, and narrowly distributed droplets in a continuous phase, which acts as “nanocontainers” were the polymerization takes place. The system is obtained by high shear and the high stability of the droplets is ensured by the combination of the amphiphilic component, the surfactant, and the osmotic agent, which is soluble and homogeneously distributed in the droplet phase. The osmotic agent has a lower solubility in the continuous phase and therefore builds up an osmotic pressure in the droplets counteracting the Laplace pressure, preventing the so called Ostwald ripening. RHC is a cheap polymer widely used for solventborne coatings and pressure sensitive adhesives. Using the as osmotic agent in the miniemulsion polymerization can lead to a higher hydrophobicity for the acrylic latex film, leading to latexes with particle sizes, size distributions and stability comparable to those obtained using n-hexadecane (HD) as osmotic agent. However, when using RHC, the monomer conversion and molecular weight were lower indicating the occurrence of a chain transfer reaction. Atomic force microscopy (AFM) analysis demonstrated that a smooth film surface with phase separated morphology was formed when using RHC. Tests in an anticorrosive paint formulation showed fast hardness development for RHC comparing to HD. Comparing with a market resin reference both RHC and HD had equivalent adhesion results on steel panels but higher final hardness. However lower gloss were found when using RHC which supports the AFM phase separation observations. The anticorrosive paints formulations were submitted to electrochemical impedance spectroscopy (EIS) analysis. Similar results were achieved for the market resin compared to RHC and HD with standard surfactant levels. When using RHC latex with less surfactant concentration better results in anticorrosive performance were achieved.

Full textIn the present document an alternative and innovative method is proposed to control and correct the color of solvent-based decorative paints in the liquid state, reducing the time and cost of the manufacturing process. The scope of the method extends from controlling the color of architectural and industrial paints to mining products, whose whiteness determines the quality and price of the ore. The paint color measurement is done in a relative way, comparing the reflection curve of the sample with the standard reflection curve. The technique is to apply the product (in the same manner as the customer applies), allow the film to dry, and measure the reflectance of the coating using a spectrophotometer. From these measurements and the equations developed by the CIE l*a*b*(1976), the color difference between the standard and the sample is measured. The final visual evaluation is performed by an experienced professional who validates the measured color difference. The proposed method uses the liquid paint reflectance to adjust the color. For this measure to be possible, specific equipment was built, called Colorcell. In this work the correlation between the dry film reflectance and the liquid paint reflectance is analyzed, the accuracy of the wet color adjustment in relation to the dry color adjustment is studied, and it is demonstrated, from the results, that the wet color control, when applied in the productive process, is effective and operates in a state of statistical control. The data prove the efficacy of the method, listing the advantages and limitations that make its use feasible in the final discussion of the results.

Full textThe aim of this study is to analyze the properties of :tive latex resins and correlate them with the performance of the paints produced with these resins. The latex resins used in this study are styrene-acrylic, acrylic, vinyl-acrylic, vinyl-Veova and styrene-butadiene. To analyze them, techniques to define the monomeric composition, particle size, Tg and MFFf have been applied. The paints have been analyzed in terms of their rheological profile, mechanical behavior by DMA, hiding, scrub resistance and porosity. By the evaluation of the results obtained from the study, it is clear that the particle size has a major role in the film formation, and therefore, in the paint performance. This relatioship is verified in the scrub resistance, hiding and porosity results. The particle size has shown relationship with the flow rheological results toa. Monomeric composition, Tg and MFFf results had influenced these properties and the mechanical properties results.

The primers are primary anticorrosive dyes, with anticorrosive property due to the presence of appropriate pigment. The most common used anticorrosive pigments are zarcão, zinc chromate, iron oxide and zinc powder. Paints based on epoxy resin are very used as primers, because their impermeability and, when associated with anticorrosive pigments, the increase in the resistance against corrosion. Films of paint-primers formulated with DGEBA epoxy resin (Diglycidyl Ether of Bisphenol A), crosslinked with polyaminoamida (Versamid 125) , and with two anticorrosive pigments, zinc chromate (toxic) and calcium silicate (not toxic), were studied by thermogravimetric analysis (TG), infrared spectroscopy (FTIR) and scanning electronic microscopy (SEM). Kinetic parameters, such as activation energy, were calculated by TG, using Ozawa-Wall-Flynn and Kissinger methods. Change in the mechanism of epoxy paint degradation was observed in the presence of the two pigments. Primer with calcium silicate was more thermally stable than that with zinc chromate, based on IPDT values. The immersion of primers films in hydrochloric acid in the concentrations range from 10-5 to 6,0 M led to a decrease in the thermal stability. The most affected primer was that with zinc chromate, in which porous was detected by SEM after the immersion in acid solution. The primer with calcium silicate has the advantage of being more thermally stable and more resistant to acid attack, in addition to its more important ecological property, the non toxicity.
Os primers são tintas primárias que funcionam como fundo anticorrosivo quando aplicados sobre metais. As suas propriedades anticorrosivas devem-se os pigmentos usados na sua composição, sendo os mais comuns o zarcão, o cromato de zinco, o óxido de ferro e o pó de zinco. As tintas à base de resina epoxídica são bastanteutilizadas como primers, pois após a cura estas tornam-se impermeáveis e, quandosão associadas a pigmentos com propriedades anticorrosivas, aumentam a resistênciado substrato à corrosão. Películas secas de tintas-primers formuladas com resinaepoxídica DGEBA (Éter Diglicidil de Bisfenol A), reticuladas com umapoliaminoamida (Versamid 125), e com dois pigmentos anticorrosivos, um tóxico (cromato de zinco) e outro não-tóxico (sílica trocadora de cálcio) foram estudadas através das técnicas de termogravimetria (TG), infravermelho (FTIR) e microscopia eletrônica de varredura (MEV). Através de TG foram determinados parâmetros cinéticos, como a Energia de ativação, tanto pelo método de Ozawa-Wall-Flynn, quanto de Kissinger. Verificou-se que o mecanismo de degradação das tintas epoxidícas é alterado na presença dos pigmentos. A estabilidade termo-oxidativa do primer com cromato de zinco, baseada nos valores de IPDT, é menor do que a do primer com o pigmento silica cálcio. A imersão dos primers em ácido clorídrico, nas concentrações de 10-5 até 6,0M, reduz a estabilidade térmica, sendo o mais afetado aquele contendo cromato de zinco. Neste ocorre a formação de poros, detectados pela MEV. O uso do pigmento anticorrosivo sílica cálcio apresenta, além da vantagem da não toxidade, maior estabilidade termo-oxidativa e maior resistência a ambientes ácidos do que o pigmento cromato de zinco.

The purpose of the present study was to intercept the waste ink from offset in ceramic material, as some residues of compensated graphite inks are as hazardous by NBR10004, other toxic materials in its composition, such as lead and antimony. Using factorial planning it was observed that a residue addition did not cause large eyes on the actual porosity and apparent porosity of the sintered ceramics. By means of the results obtained it was observed that at both 1100 ° C and 1200 ° C the test bodies inerted the heavy metals because the metals of the test were not leached according to a standard by the ABNT NBR 10005: 2004 standard. The incorporation of waste into the ceramic mass is economically feasible and socioambiemalmente favorable, because it reduces the cost of the waste of ink to be discarded as well as it avoids its disposal in the environment.
O presente estudo teve o objetivo de intertizar resíduos de tinta offset em material cerâmico, pois alguns resíduos de tintas gráficas offset são considerados como perigosos pela NBR10004, por conter materiais tóxicos em sua composição, como o chumbo e o antimônio. Utilizando planejamento fatorial observou-se que a adição de resíduo não causou grandes alterações na porosidade real e porosidade aparente da cerâmica sinterizada. Por meio dos resultados obtidos observou-se que tanto a 1100°C quanto a 1200°C os corpos de prova inertizaram os metais pesados pois não ocorreu lixiviação dos metais em ensaio segundo a norma pela norma ABNT NBR 10005:2004. A incorporação de resíduo a massa cerâmica é economicamente viável e socio-ambiemtalmente favorável, pois diminui o custo do resíduo de tinta a ser descartado bem como evita seu descarte no meio ambiente.

O objetivo do presente trabalho é apresentar as diferentes abordagens dadas ao temo mímesis, originalmente concebida como meio de expiação das emoções, e depois utilizada pela filosofia, que lhe imputou outros significados. Tal estudo propiciou o entendimento da maneira com a qual pintura e fotografia foram analisadas dentro desse cenário, onde em muitos momentos tanto o pintor quanto o fotógrafo foram tidos como reprodutores ou capturadores do real. Outro ponto abordado é sobre o uso de dispositivos ópticos e lentes durante o processo de concepção e produção da pintura desde o século XV. Por fim, essa pesquisa apresenta a poética contida no trabalho prático, momento em que o artista-pesquisador busca refletir e compreender os processos de construção de possível "pele pictórica" por meio da tinta óleo como meio de entendimento do envelhecimento dos seus entes próximos e com isso pretende ter contato com os processos em que estará inserido no futuro. _________________________________________________________________________________ ABSTRACT
This study aims at displaying the different approaches to the term mimesis, originally conceived within the rite of emotional atoning, and later taken by philosophy, which has been attributed other meanings. This study provided an understanding of the manner in which photography and painting have been analyzed in this scenario, where in several moments both the painter and photographer have been considered captors and reproducers of reality. Another point that has been approached is about the use of optical devices and lenses during the conception process and painting procedures since the 15th Century. Finally, this research presents the poetry within the work practice, the moment in which the artist-researcher attempts to reflect and comprehend the construction processes of possible pictorial skin throughout oil paint by means of understanding the aging of their loved ones and later the intention of obtaining contact with the procedures which will be inserted in the future.

Full textAtualmente, os documentos impressos ainda são bastante utilizados apesar de vivermos na era digital. As tecnologias de impressão estão, cada vez mais, acessíveis a todos podendo, por isso, ser usadas para fins ilegais, como por exemplo contrafação ou falsificação de documentos. A análise forense a documentos tem como objetivo primordial averiguar a autenticidade dos mesmos, sendo uma das vertentes a análise da tinta presente. O objetivo deste trabalho, realizado no Laboratório de Polícia Científica da Polícia Judiciária, foi estudar a eventual influência de alguns fatores nos resultados da análise de tinta de jato de tinta, através das técnicas de microespectrofotometria e de cromatografia de camada fina. Realizou-se um estudo comparativo não só entre a tinta obtida por impressão nos diferentes níveis de qualidade disponíveis nas opções das impressoras, mas também com a tinta recolhida diretamente dos tinteiros. Foram igualmente efetuadas comparações entre a tinta impressa em diversos papéis de marcas, gramagens e cores diferentes. Procedeu-se também à comparação da tinta, impressa no mesmo modo de impressão e no mesmo suporte, mas após sujeita a diferentes tratamentos físicos, químicos e de exposição à luz. Demonstrou-se que as técnicas usadas são muito robustas, uma vez que, os resultados da análise à tinta de impressão são idênticos entre si, independentemente da forma de obtenção da amostra de tinta (qualidade de impressão e/ou recolha direta do tinteiro), do papel utilizado e do tratamento a que o conjunto tinta + papel foi sujeito. Porém, concluiu-se que a cor de fundo do papel pode alterar os espectros de absorção da tinta, dificultando deste modo a análise por microespectrofotometria.
Although we live in the digital era, printed documents still have a very important role in our daily life. Printing technologies became more accessible and affordable leading to its illegally misuse, such as in fraud and document forgeries. The forensic analysis of documents aims to verify their authenticity. One of its fields of study is the analysis of the printed ink used in those documents. The purpose of this research, that took place at the Forensic Science Laboratory (LPC) of the Portuguese Criminal Police (Polícia Judiciária), was to study the influence of some factors on the analysis of inkjet ink, using microspectrophotometry and thin-layer chromatography. To accomplish these objectives, it was carried out a comparative study between several ink samples obtained from different printing modes, offered on the printing properties menu, as well as ink collected directly from selected cartridges. Comparisons have also been made between the printed ink on various papers brands, weights and different colours. Furthermore, comparisons between ink samples were performed after the paper support was subjected to different physical, chemical and light exposure treatments.This investigation has proven that both applied techniques are very robust, since the results were similar to each other, regardless of the origin of the ink sample (printing modes and/or collected directly from cartridge) and the type of paper selected. Even ink subjected to physical and chemical treatments presented similar results. Nevertheless, this project showed that coloured paper can interfere with absorption spectra, causing difficulties on microspectrophotometry analysis.

The object of study was the printing by Robocasting of capacitive sensors in silver nanoparticles ink on Acrylonitrile Butadiene Styrene (ABS) and Polypropylene (PP) plates, injected in Simoldes Plásticos, its structural and microstructural characterization and in terms of electrical performance and comparison (benchmarking) with other capacitive sensors produced with other materials and other processes, namely conductive polymer filament by Fused Deposition Modeling (FDM) and copper by Computer Numerical Command (CNC). In this context, the present project experimentally contemplates: i) the characterization of the ABS and PP plates and the silver ink, ii) the drawing and printing of the sensors, iii) the printing of the capacitive sensors by Robocasting and iv) the physical – chemical, structural and electrical characterization of the capacitive sensors. The chemical and physical characterization of the ABS and PP plates and the silver ink allowed to relate their properties to the optimization of the prints. Based on commercial silver nanoparticles ink, capacitive sensors with different geometries were printed by Robocasting on the plates. The prints proved to be highly complex and dependent on the viscosity of the ink, the sensor printing was optimized. The electrical behaviour of sensors printed with silver ink with different thermic treatments, these proved to be uniform. [...]. The performance of the printed sensors is thus comparable to the performance of the traditional copper sensors, which demonstrates the potential and the opportunity for the capacitive sensors printed by AM in the universe of the automotive industry.

Full textO recente ajustamento verificado no Mercado das Tintas em Portugal obrigou as empresas a reorganizarem os seus planos de negócio assim como a redefinir o seu negócio e respectivas estratégias. No passado recente, a tendência do mercado tem sido para verificar uma diminuição do Preço Médio de Venda, forçando as marcas Premium a alargar a sua actividade a outros segmentos. A competir num mercado altamente fragmentado, a empresa Tintas Robbialac SA decidiu começar a ser parte activa no segmento médio-baixo através da aquisição da Tintas Vip. Sendo provavelmente a melhor alternativa disponível para uma penetração rápida e eficaz nesse segmento, o negócio da Tintas Vip levou a uma reorganização a nível da estratégia do comprador. Assim, a principal preocupação nesta aquisição foi a nível da estratégia. Competir no segmento médio-baixo tornou-se essencial assim como, simultaneamente, era imperativo que a Tintas Robbialac SA prevenisse a canibalização entre o seu portfolio e o das suas subsidiárias.
