Organic dyes have been widely used in various branches of dyeing industries. These compounds are known to be very toxic, mutagenic, cancinogenic only cause aesthetic pollution and irreversible damage to aquatic ecosystems and human health. Are recalcitrant contaminants due to its high stability and resistance to photobleaching and bio. Given this context, the search for technologies that can minimize the effects of such pollutants is required. In recent decades the Electrochemical Oxidation Process Advanced (PEOAs) based on the generation of strongly oxidizing species (radicals ●OH) offer promising approaches for the prevention of problems caused by industrial effluents. This study analyzed the degradation and mineralization of textile dyes and the study of a real effluent in order to assess the feasibility of PEOAs: Electro-Fenton (EF), Photo Electro-Fenton (PEF) and anodic oxidation (AO), and these methods still was studied the Solar Fotoelectro-Fenton (SPEF) in a pre-pilot plant, in order to study the electrochemical treatment on an industrial scale. In the study has compared the effect of PEOAs in the removal of color, TOC and decay kinetics of degradation of the compounds, and also for using the Congo Red (CR) SPEF studies were performed mineralization current efficiency (MCE). The best results are given to the treatment of the PEF for all the studied dyes. From the results it was possible to choose the PEF as the most effective and promising for application of treatment when compared to other methods of treatment, and prove from SPEF that the process can be used in industrial scales, since this method PEF has been improved and solar irradiation replaced the UVA lamp.

Even after its abolition, the slave labor still exists in the world. In a new socio-historic context, the shackles and slave quarters have been left behind, nowadays the workers are tempted, subjected to degrading conditions and have their rights retrenched. The contemporary slave labor has been emerging as subject of research in the Organizational Studies since the early 2000s, calling attention to many gaps to be filled about the way organizations all around the world use this practice. Contemporary slave labor is found in many and various economic activities, since coal to textile industries or even stores. In this dissertation, we have incorporated the consumption dimension to the field of Organizational Studies, discussing the modern slavery, aiming to understand the consumers’ point of view about this topic, that is, we have researched the consumers’ interpretations concerning the slave labor in the fashion industry. Our objective is to analyze consumer’s argumentative construction in the decision of buying or not products made by industries from the fashion field that were denounced because of slave labor usage. We have adopted fashion industry as research focus because it obscures the reflection of the consumers that feel like in a new world while shopping, a world of beauty and fantasy, seeking their own satisfaction. Furthermore, the Brazilian fashion industry is one of the biggest of the world (ABIT, 2015), with a huge symbolic strength in the country. We have realized a qualitative research using semi-structured interviews with 35 consumers to identify their arguments according to the criteria defined by Liakopoulos (2002): data, propositions, guarantees, supports and refutations. The data are the statements used by the interviewees categorically, that is, those which are clear in the interviews. The propositions are what qualifies and justifies the used data. The guarantees are related to the nature of the data, they are what gives the sense to the data and are introduced implicitly in the interviewee speech. The supports are universal premises introduced in order to legitimate the arguments. The refutations, when present, counter the used arguments. As results, we’ve found consumers who developed arguments pro-consumption and anti-consumption and who have defended ideas about the responsibility of different actors for the existence of this practice and for the fight against it. From these two categories: (1) pro-consumption – consume despite the complaints and (2) anti-consumption – don’t consume, because of the accusations; we have identified the following argumentative lines: skepticism, faultfinding and moral engagement. By the end, we have presented the interviewees’ argumentative construction and the obtained results.

Untreated effluents that reach surface water affect the aquatic life and humans. This study aimed to evaluate the wastewater s toxicity (municipal, industrial and shrimp pond effluents) released in the Estuarine Complex of Jundiaí- Potengi, Natal/RN, through chronic quantitative e qualitative toxicity tests using the test organism Mysidopsis Juniae, CRUSTACEA, MYSIDACEA (Silva, 1979). For this, a new methodology for viewing chronic effects on organisms of M. juniae was used (only renewal), based on another existing methodology to another testorganism very similar to M. Juniae, the M. Bahia (daily renewal).Toxicity tests 7 days duration were used for detecting effects on the survival and fecundity in M. juniae. Lethal Concentration 50% (LC50%) was determined by the Trimmed Spearman-Karber; Inhibition Concentration 50% (IC50%) in fecundity was determined by Linear Interpolation. ANOVA (One Way) tests (p = 0.05) were used to determinate the No Observed Effect Concentration (NOEC) and Low Observed Effect Concentration (LOEC). Effluents flows were measured and the toxic load of the effluents was estimated. Multivariate analysis - Principal Component Analysis (PCA) and Correspondence Analysis (CA) - identified the physic-chemical parameters better explain the patterns of toxicity found in survival and fecundity of M. juniae. We verified the feasibility of applying the only renewal system in chronic tests with M. Juniae. Most efluentes proved toxic on the survival and fecundity of M. Juniae, except for some shrimp pond effluents. The most toxic effluent was ETE Lagoa Aerada (LC50, 6.24%; IC50, 4.82%), ETE Quintas (LC50, 5.85%), Giselda Trigueiro Hospital (LC50, 2.05%), CLAN (LC50, 2.14%) and COTEMINAS (LC50, IC50 and 38.51%, 6.94%). The greatest toxic load was originated from ETE inefficient high flow effluents, textile effluents and CLAN. The organic load was related to the toxic effects of wastewater and hospital effluents in survival of M. Juniae, as well as heavy metals, total residual chlorine and phenols. In industrial effluents was found relationship between toxicity and organic load, phenols, oils and greases and benzene. The effects on fertility were related, in turn, with chlorine and heavy metals. Toxicity tests using other organisms of different trophic levels, as well as analysis of sediment toxicity are recommended to confirm the patterns found with M. Juniae. However, the results indicate the necessity for implementation and improvement of sewage treatment systems affluent to the Potengi s estuary

Portugal’s manufacturing sector has a significant importance both in national income and employment. As has been pointed out by several researchers, the traditional methods of analysis fail to grasp all the dimensions of economic competitiveness. This dissertation is then, at its core, an analysis of Portugal’s manufacturing industry in terms of the latter’s value added to production and impact to employment under the framework of global value chains. The current dissertation seeks to study in which way the Portuguese manufacturing industry, and its respective sectors, has a direct and indirect impact on the creation of value added and employment and how this impact can be measured. For development of this work the input-output approach for calculation of multipliers and the new framework proposed by Timmer et al. (2013) for calculation of GVC income and GVC jobs indicators were used, elaborated on the basis of the WIOD project dataset. Moreover, to illustrate the application of the provided methodology the Portuguese textile industry was used as an example. It was found that the changes in final demand of such sectors as Pulp, Paper, Printing and Publishing; Machinery, Nec and Textiles and Textile Products would have a larger impact on generated value added than other manufacturing sectors. At the same time, employment created by the changes in final demand would be more impacted by such sectors as Food, Beverages and Tobacco; Wood and Products of Wood and Cork and Textiles and Textile Products. In this regard, the number of low-skilled workers in Portugal seems to be more effected by changes in final demand, than those occupied by higher -skilled individuals. Moreover, it was found that the distribution of GVC income and GVC jobs for the Portuguese manufacturing industry shares a similar outlook. However, upon closer inspection of GVC labour distribution by skill levels there seems to exist a general progression in which low-skilled jobs requirements are met by local resources, while the need for higher skilled jobs require a greater “off-shoring” of work The results obtained through calculations of presented multipliers provide a powerful tool for policy makers in strategic planning of development of national economy. Using the provided methodology and obtained results, a government and supranational organizations could define which industry would have the greatest impact for an additional unit of output generated through the economy, and thus define the sectors for further investments.

A tese teórico-prática de doutoramento apresentada contempla a investigação, a criação, a produção e a conceptualização da instalação artística interativa intitulada Por baixo da pele outra pele. A Obra é constituída por três objetos tridimensionais concebidos à escala humana. Recorre a materiais flexíveis, como têxteis, convidando o público (interator), à envolvência física, numa relação corporal sensorial e sensual com a obra. Os objetos contêm dispositivos técnicos interativos e sensores tácteis, que, ao serem utilizados, desencadeiam estímulos multissensoriais no espectador. A instalação interativa focaliza a experiência háptica e íntima do interator considerando os seus mecanismos sensoriais e cognitivos como um potencial aparato na construção de experiências fenomenológicas, singulares e individuais. A autora considera a interatividade enquanto elemento potenciador da experiência estética visual háptica. Na argumentação conceitual da obra, reflete-se sobre o tema da visualidade háptica interativa a partirdos conceitos de ecrã, corpo e interface, assim como de endossensorialidade. Instrumentam-se metodologias de investigação em ação, experimentais e observacionais. Apresentam-se os processos investigativos, criativos e técnicos necessários ao desenvolvimento e à materialização da instalação artística. A investigação revela-se de grande interesse para o avanço da pesquisa de novas linguagens experimentais apresentando estratégias de criação artística que, ao privilegiarem o corpo físico e fenomenológico do interator, transpõe a experiência háptica interativa para um grau interno de imersão motoro-sensorial; Underneath the skin another skin: art installation. Body, screen and interface towards an interactive haptic visuality. Abstract: The theoretical-practical doctorate dissertation presents the research and conceptual framework behind, and the processes leading to, the creation and production of the interactive installation art piece Underneath the skin, another skin. The piece is presented in the shape of three human-scale tridimentional objects. It is made from flexible materials, such as textiles, inviting the (interacting) audience, to physically engage in a bodily sensorial, and sensuous, relationship with the artwork. The objects enclose interactive devices and tactile sensors that, when used, trigger in the interactor multiple sensorial stimuli. The interactive installation focuses on the interactor's intimate haptic experience taking in consideration his or hers sensorial and cognitive mechanisms as a potential apparatus in the construction of unique individual phenomenological experiences. The author understands interactivity as a triggering element into an haptic visual aesthetical experience. The supporting conceptual reasoning deals with thought and criticism on interactive haptic visuality applied to the concepts of screen, body and interface, as well as with that of endo-sensoriality. The dissertation describes the use of experimental and observation research methodologies. It also elaborates on the research, creative and technical processes at play in the installation's development and realization. The research at hand has shown great potential for the further development of new experimental languages, as it presents art-creation strategies privileging the interactor's physical and phenomenological body, and thus able to take the interactive haptic experience onto an greater inner level of motor-sensorial immersion.

A cidade de Kanchipuram, no Estado de Tamilnadu, sul da Índia, é sinónimo de templos hindus, mas também do sari em seda. A migração de comunidades de tecelão para esta cidade começou durante o reinado da Dinastia Chola nos Séculos 8-13 d. C. Anteriormente, o pano de seda foi considerado como tecido dos Deuses e os tecelões satisfizeram as necessidades religiosas do templo da cidade. Paulatinamente, um tecido de seda torna-se, tanto um tecido dos "mortais", como dos Deuses, e houve um aumento da procura dos têxteis em seda, especialmente, do sari em seda. A particularidade dos tecelões de Kanchipuram reside na sua técnica complicada de tecelagem e nos ricos motivos que são uma expressão da paixão do tecelão. Nosso trabalho de investigação centra-se nas técnicas de tecelagem e no seu produto final - o sari - para destacar a sua singularidade. Neste contexto, quero propor um projecto de documentação dos motivos do sari, para ilustrar um dos principais meios de valorização desta tradição de tecelagem que remonta a vários séculos. RÉSUMÉ: La ville de Kanchipuram, située dans l'état du Tamilnadu, dans le sud de l'Inde, fait souvent écho aux temples hindous mais également au sari en soie. Les tisserands ont migré à l'époque Chola (850- 1279 ap.J.C.) pour répondre aux besoins religieux de la ville car au départ, la soie était un tissu destiné à I 'usage des dieux. Au fur et à mesure, la soie est devenue aussi bien un tissu destiné aux 'mortels' qu'aux dieux. Ces tisserands ont connu par la suite, une forte demande, plus particulierement, pour les saris en soie. La particularité des tisserands de la ville de Kanchipuram réside dans sa technique laborieuse de tissage et dans les motifs élaborés parle billet desquels s'exprime la passion du tisserand dans sa tâche. Le présent mémoire s'attache à la technique de tissage et à son produit final - le sari - pour mettre en valeur son unicité. Dans ce cadre, je propose un projet de documentation des motifs des saris pour illustrer un des vecteurs clés de valorisation de cette tradition de tissage qui remonte à plusieurs siecles. ABSTRACT: The city of Kanchipuram, located in the State of Tamilnadu in southern India, is synonymous with Hindu temples and silk saris. The migration of weaver communities to the city started during the Chola reign (81 131 centuries A.D). Early on, silk was considered the cloth of the gods and these weavers met the needs of the temple city by producing silk textiles for religious use. Gradually, silk became a cloth as much for the 'mortais' as for the gods and demand increased for silk textiles, especially saris. The importance of Kanchipuram weaving lies in its complex techniques and rich motifs as expressions of the. weaver’s passion. This text examines the weaving techniques popularly known as the korvai technique, as well as the saris produced using this technique. ln addition, it attempts to catalogue certain motifs woven into the saris as a first step in promoting and valorizing the cultural richness of an art dating back several centuries.

O trabalho se refere a um estudo sobre a industrialização, a dinâmica territorial e as implicações socioambientais em Três Lagoas/MS. O Parque Industrial decorre do processo de (des)concentração/(re)concentração industrial, no Brasil. Há intensa dinâmica territorial, que se dá a partir do processo industrial, que se circunscreve em três Distritos Industriais. Analisaram-se a estrutura e a dinâmica industrial, bem como os conflitos estabelecidos entre as forças produtivas. Também se avaliaram as alterações decorrentes da incorporação de tecnologia, produtividade e os reflexos no uso e ocupação das terras no campo. Ainda averiguou-se se há riscos de contaminação pelas indústrias, seja pela contaminação das águas subterrâneas e do solo, seja pela emissão de gases na atmosfera, os quais foram avaliados com vista à elaboração de um plano de redução dos riscos de eventos perigosos e contaminação ambiental. No Distrito Industrial I, há 22 empresas, sendo 11 ligadas a construção civil, de baixa periculosidade, e, perigosas destacam-se 3 metalúrgicas, uma química, uma de plástico e uma carvoaria. No Distrito Industrial II, concentram-se 27 empresas, destas apenas 3, a de alimentos, bebidas e de construção civil não são perigosas. Destacando-se dentre a perigosas, 8 indústrias têxteis, 6 metalúrgicas e 6 petroquímicas. O Distrito Industrial III situa-se fora do núcleo urbano, e se destina às megaindústrias: fábricas de papel e celulose, - consórcio Fibria/Internacional Paper - e uma de fertilizantes da Petrobras. As indústrias do Distrito Industrial II contam com aparato tecnológico mais avançado, isto é, coadunam as novas tecnologias do atual período técnico-científico e os incentivos fiscais – doação de terreno, isenções de impostos - com o aparato de objetos espaciais que o município oferece - vias intermodais, energia elétrica, e, a possibilidade da exploração da força de trabalho com baixos salários. Esses empreendimentos promoveram nova dinâmica territorial, criando novos sentidos e funções, impondo novos valores e cultura, inclusive os estilos de moradia, pois a expansão da periferia da cidade agora, não dá lugar somente aos conjuntos habitacionais populares, mas também aos luxuosos condomínios horizontais fechados; além do aumento da opção de moradias em condomínios horizontais. A paisagem urbana se metamorfoseia, pois a territorialização do capital industrial delineia novas territorialidades, a cidade ganha ares de cidade grande.
