Characterization of protein hydrolysates of cosmetic use by CE-MS

Protein hydrolysates have been used as active principles in cosmetic products conferring different properties to the final formulations, which are mostly controlled by the peptide size and its amino acid sequence. In this work, capillary electrophoresis coupled to mass spectrometry analyses were carried out in order to investigate such characteristics of protein hydrolysates. Samples of different origins (milk, soy and rice) were obtained from a local company, and were analyzed without a previous preparation step. The background electrolyte (BGE) and sheath liquid compositions were optimized for each sample. The best BGE composition (860 mmol/L formic acid - pH 1.8 - in 70: 30 v/v water/methanol hydro-organic solvent) was chosen based on the overall peak resolution whereas the best sheath liquid was selected based on increased sensitivity and presented different compositions to each sample (10.9-217 mmol/L formic acid in 75: 25-25: 75 v/v water/methanol hydro-organic solvent). Most of the putative peptides in the hydrolysate samples under investigation presented molecular masses of 1000 Da or less. De novo sequencing was carried out for some of the analytes, revealing the hydrophobicity/polarity of the peptides. Hence, the technique has proved to be an advantageous tool for the quality control of industrial protein hydrolysates.

Qu est-ce que c est?: uma HQ autobiográfica de Fábio Moon e Gabriel Bá.

Partindo da ideia de que as histórias em quadrinhos, apesar de serem consideradas um gênero híbrido, possuem também uma linguagem autônoma, este trabalho busca investigar por meio de análise de conteúdo uma história em quadrinhos (HQ)autobiográfica dos gêmeos paulistas Fábio Moon e Gabriel Bá, Qu’est-ce que c’est?, publicada pela primeira vez em inglês na coletânea Autobiographix (Dark Horse Books, 2003) e republicada em português no livro Crítica (Devir, 2004). Serão analisados recursos estéticos e narrativos, tentando descobrir também quais são as particularidades de uma HQ autobiográfica. A história narra a saga dos irmãos durante uma viagem a Paris, onde foram visitar museus e colher referências para seu trabalho. No metrô, eles se depararam com uma gangue da periferia.

Análise o comportamento hidrodinâmico e sedimentológico do estuario do Rio Piranji - CE (NE/Brasil)

Cerca de dois terços das maiores áreas metropolitanas mundiais estão nas proximidades dos estuários, portanto são regiões comumente sujeitas à situações de risco impostas pela pressão populacional. Instalações portuárias, efluentes diversos, uso indevido das suas margens, estão entre os riscos potenciais à grande diversidade de seus recursos naturais. A ação das marés, das ondas e o aporte fluvial interagem tornando bastante complexa a caracterização do seu funcionamento. A presente dissertação foca os seguintes aspectos: hidrodinâmica, transporte de sedimentos em suspensão, sedimentologia, morfologia e classificação do ambiente. A hidrodinâmica e o transporte de sedimentos foram estudados em duas etapas de campo em condições de maré de sizígia e de quadratura, cada qual com abrangência de dois ciclos de maré (25 hs). Estas etapas foram realizadas numa estação fixa com medições de: maré, velocidade da corrente, material em suspensão, sólidos totais dissolvidos, salinidade, pH, oxigênio dissolvido e temperatura. As características sedimentológicas foram avaliadas pela coleta de sedimentos de fundo em 24 pontos. Os aspectos morfológicos foram reconhecidos por uma batimetria detalhada e por aerofotografias. Os resultados revelaram a dominância das correntes de maré vazante em sizígia e de enchente em quadratura. O fluxo total de sedimentos por ciclo de maré na sizígia foi de 71 ton. (vazante), enquanto que na quadratura foi de 2,2 ton. (enchente). Os sedimentos de fundo variaram de areia muito grossa a silte. A profundidade máxima foi de 7,4 m (maré alta de sizígia). A comparação das aerofotografias revela a instabilidade morfológica da desembocadura. Relaciona-se este fato à influência variável da deriva litorânea e da descarga hidráulica. Este estuário foi classificado como: de frente de barreira arenosa; de circulação do tipo xvi parcialmente misturada e, por vezes, verticalmente homogênea; de Tipo 2b (quadratura); de tipo intermerdiário 2a e 2b (sizígia); de negativo; de mesomaré e de energia mista.

Qual a evolução do tecido empresarial da RAM a nível sectorial no período pós-adesão à CE (1988-2008)?

O presente estudo tem como principal objectivo analisar o desempenho global e por sector de actividade do tecido empresarial da RAM no período 1988-2008 através da análise de dados financeiros. A relevância do estudo baseia-se na reflexão da resposta dada pelo tecido empresarial regional aos desafios que foram surgindo ao longo do período referido, e na análise do espírito empresarial e das linhas estratégicas de actuação que pautaram o tecido empresarial a nível das diferentes actividades na RAM. Para a realização deste estudo quantitativo utilizamos uma amostra de conveniência que contêm dados contabilísticos anuais de 545 empresas do tecido empresarial regional, que participaram na iniciativa anual das 100 Maiores Empresas da RAM ao longo dos 21 anos em estudo e que constituem, eventualmente, a única base de dados de cariz semipúblico da região. Os dados foram obtidos através de recolha exaustiva nas instituições responsáveis pelo tratamento da informação disponibilizada pelas empresas concorrentes (Previsão, ECAM), consolidada por pesquisa em jornais (DN, JM), revistas e dados recolhidos no arquivo regional. Estas fontes constituem-se como um precioso instrumento de recolha de dados financeiros de difícil acesso. No tratamento dos dados foram utilizados métodos de estatística descritiva, taxas de crescimento e números índices de base fixa e aplicado teste de correlação de «Pearson». Obteve-se como principais resultados a evolução anual positiva do indicador Volume de Negócios (7,95%) e Activo Líquido (12,23%), Capital Próprio (11,04%), Cash-Flow (12,40%) e Produtividade (2,51%). Os resultados obtidos permitem concluir que houve crescimento empresarial na RAM no período em estudo. As actividades industriais, comerciais e de serviços cresceram a ritmos diferenciados ao longo do período de análise, com predominância para o crescimento do sector terciário, alicerçada nas actividades comerciais e de serviços, que evidenciaram crescimento superiores à actividade industrial.

Microcrédito emancipatório no nordeste do Brasil? : estudo de caso do Crediamigo Comunidade nos municípios de Caucaia-Ce e Maranguape-Ce

This piece of work consists in a study case of Crediamigo Comunidade, a product from the portfolio of Crediamigo Program of Banco do Nordeste, that uses the methodology of the Comunitary Banks in the concession of low amount loan to poor communities. The main question consists to understand how the Crediamigo Comunidade is characterized faced to the conflict of emancipatory versus liberal paradigms, that exists in the microcredit area. The main objective will analyze how the mechanisms: social capital, empowerment, formation to credit education and better conditions for economic and social issues promoted in the specific objectives of this product, before the dipute between these paradigms. The method adopted analyzed, in a longitudinal perspective, the three years of the product s existence (jun/2005 to jul 2008). Primary and secondary data made possible to identify qualitatively, emancipatory and non emancipatory attributes in the actions and results of Crediamigo Comunidade. It is concluded that the Crediamigo Comunidade works in a liberal logic of the Crediamigo Program, consequently, his focus is not in the emancipation of the poorest clients. The empowerment is individual and not communitary or Freiriano ; the social capital relations enlarges itself in its bounding and bridging ties, but not in its linkage ties, to have access to politic actors and consequently communitary strengthen. All the formation in the Crediamigo is strictly commercial. These characteristics happen by the liberal paradigm in the Crediamigo management and of all of its products, including the Crediamigo Comunidade

A importância do microcrédito para os empreendedores: um estudo com os grupos solidários de Fortaleza /CE

This study aims to understand the changes in the improvement of economic and social conditions of small entrepreneurs who participate in solidarity groups linked to the Non-Governmental Organization (NGO) "X" in Fortaleza city, Ceará, through the use of productive-guided microcredit. It is come a research in exploratory and descriptive nature, with a quantitative and qualitative approach. Data were collected from the small entrepreneurs by applying a questionnaire, as well as through structured interviews with group leaders. They were worked on issues relating to income generation, employment generation, housing and health conditions, dietary pattern and leisure activities of small entrepreneurs and their families before and after the union to solidarity groups and use of productive-guided microcredit. The research showed that the use of microcredit has interfered with social and economic life of these small entrepreneurs, generating positive effects

Filhos da independência: etnografando os estudantes bissau-guineenses do PEC-G em Fortaleza-CE e Natal-RN

Notre travail propose de comprendre l`immigration africaine contemporaine du Brésil à travers l'univers des étudiants guinéens participant au Programme Étudiants « Convênio de Graduação » (PEC-G) dans les villes de Fortaleza dans l'Etat Ceará et Natal dans l'Etat de Rio Grande do Norte, en étudiant leurs stratégies de convivialité et d'adaptation. Les étudiants étrangers sélectionnés dans ce programme font leur licence gratuitement dans les Instituts d'Enseignement Supérieur (IES). Pour accéder à ce programme ils doivent répondre à certains critères : montrer qu'ils sont en mesure de payer leurs frais au Brésil, avoir le bac ou un diplôme équivalent et maîtriser la langue portugaise lorsqu'ils sont originaires d'un pays n'appartenant pas à la Communauté de Pays de Langue Portugaise (CPLP). Les étudiants qui participent à des programmes de développement socio-économique contractés entre le Brésil et leurs pays d'origine sont prioritaires. Ces accords les contraignent à rentrer dans leurs pays d'origine et de travailler dans le domaine dans lequel ils ont été diplômés une fois les études terminées. Les étudiants, qui arrivent au Brésil porteurs de leurs identités ethniques guinéennes, entrent en contact avec la société brésilienne et acquièrent ainsi une « identité hybride ». C'est dans ce contexte que ce travail analyse le quotidien des étudiants africaines au Brésil avec un regard porté sur les étudiants de Guinée-Bissau à Fortaleza et à Natal comprendre l'expérience des étudiants qui vivent en terre étrangère. Ainsi, le lieu (Brésil) prend toute sa valeur par rapport au distant (Guinée) autrefois lié par l'histoire coloniale et aujourd'hui lié par des relations internationales ou diplomatiques. Finalement, la construction d'une « nouvelle » identité ethnique, d'une culture guinéenne au Brésil s'opère dans une célébration mobile c'est-à-dire successivement formée et transformée en relation avec les formes à travers lesquelles l'individu est représenté ou interpelé dans les systèmes culturels dans lesquels il est impliqué.

A cultura de índio, seu menino, vem de longe aqui : formação histórica e territorialização dos Tremembé/CE

This dissertation is based on the ethnography of a strategic selection of three Tremembé ethnic situations, which are situated in the backlands of Acaraú and Itarema, municipalities located in Ceará State (Northeast Brazil). My main aims are the following. Firstly, I reconstitute the historical and social formation of three localities, called Lagoa dos Negros, Telhas, and Queimadas, related to a particular origin myth which refers to Almofala, an extinct colonial Aldeamento in the seashore, where the Tremembé indians and other native populations were converted and gathered under missionary administration. According to the origin myth, these three localities were set up after a strong drought which happened in 1888 (the so called three eights) when a group of Tremembé families moved to the countryside and established close to the Lagoa dos Negros and, later on, they were segmented into smaller groups which started to live in other areas and places not far from the former location. Notably, I develop an anthropological approach to understand the historical formation of these three localities. Secondly, I analyze some processes of territorialization, which were emerged from the 1980s and had important consequences to these indigenous families throughout the next two decades. This historical dimension is re-appropriated and ressignified in ethnic terms. A third point of my work is the analysis of the construction of territorialities and also the cultural and symbolic dimensions which are formulated by the Tremembé Indians who live in these localities. Therefore, I investigate some cultural traditions and rituals, such as the Torém dance, but I also examine their multiple semantics, which constitute a transversal direction throughout the history understood by the Tremembé of the different social situations I researched. To sum up, there is a process of cultural actualization, which is still going on and presents itself through the ludic sphere as well as their political and religions dimensions, which are usually associated to the ritual presentation of the Torém

Adequação bioclimática para os espaços urbanos abertos do centro de Fortaleza, CE

This research presents a study investigating the correlation between the environmental-physycal charcateristics of cities and the formation of its micro-climates. The study was conducted in the central area of Fortaleza characterized as a stable and consolidated area, where the city originated and currently faces serious problems in its urban dynamics. The points of measurements were determined by the elaboration and analysis of topography maps, height of buildings, land use, type of surface coating and vegetation, following the methodology of Katzschner (1997). A zoning map was then determined, according to common morphological characteristics of the 12 measurement points, which were based on a set of Romero s (2001) bioclimatic criteria. Air measurements, temperature, humidity, intensity and direction of winds were made in transect form in two different circuits in the study area, with six points of data collection in each area, in three different times: 6:00 am, 1:00pm and 7:00pm, during two periods of the year: August 2008 and March 2009. The results verified the influence of different environmental-physical types in the behavior of the climatic variables that were collected. A verticalização tão condenada em algumas situações se bem equilibrada e controlada pode reduzir as temperaturas do ar através do sombreamento dos espaços urbanos e possibilidade de maior permeabilidade a ventilação natural. The highest average air temperature and lower humidity were recorded at the point I at all times. This situation may have been in result of the high density, poor vegetation and extended paving of the ground. According to the results, it s clear the positive influence vegetation has on easing air temperature. Another indicator observed that areas with a greater variation in building heights tend to present decreased average air temperature. High rise structure, planned in accordance to urban air quality parameters, can reduce air temperatures by the shading of urban spaces and the possibility of greater penetration of natural ventilation

Barracas de Praia, praia de barracas: configuração, tipo e usos na praia do futuro, Fortaleza CE

The purpose of this dissertation is to analyse the importance of the huts of Praia do Futuro to their users and to the city of Fortaleza in Ceará through the comprehension of relations between morphological categories - in urban and edified contexts - of the establishments and their use patterns. This place is one of the main recreation and leisure areas of the city, formed by six kilometres of waterfront, corresponding to a differentiated area through the coast. This space has beach huts with varied profiles: while some more simple huts persist, great complexes are being developed, building even water parks on the beach area. This study analyses relations between:i) spatial configuration (in geometric and mainly topological terms) based on the Social Logic of Space; ii) edified typology (analysing capacity, landscap treatment and program of the huts); and iii) use and environmental perception of the beach by its frequenters. There are consistent relations between the type of hut and their localization in the urban grid, of which were identified groups with different patterns: segregated (north, central and south) and integrated (north: more integrated. and south: less integrated). Such relations also reflect, in varied patterns of use and environmental perception. In spite of their strong economy, the beach huts find themselves in a fragile legal situation because they occupy the beach area, so that this study may come to assist the decision-making for the future of the region. For a sustainable development of the area by those responsible and managers it is necessary to evaluate the cultural importance of the huts at Praia do Futuro, understanding their occupation and uses.

Visitabilidade-vivenciabilidade em assentamentos informais : um estudo da acessibilidade de percursos urbanos no Conjunto Santa Terezinha em Fortaleza-CE

This research approaches the issue of accessibility in informal settlements, seeking for the challenges and limits defined by informal urban settings, about the application of accessibility parameters. Take the empirical universe as the Conjunto Santa Terezinha, located in Fortaleza- Ce. Initially, the study presents a reflection about the housing issue in Brazil and the informal settlementes in view of the Right to the City. In this sense, the main references are, the works of Suzanne Pasternak (2008), Nabil Bonduki (1998) and Erminia Maricato (1996-97), among others. Follows with the discussion of the concepts and classifications of this type of settlement, making a content analysis of legislation and regulations relating to accessibility and proposed the discussion of the accessible route as the right strategy for the city. In another step, the methodology of 'walking together' created by Dischinger (2000) was applied in a passage previously chosen, which the researcher follows the disabled person during the journey through city making records like photos and video. The comments and perceptions are compared to the spatial analysis of urban morphology, made from the method of Del Rio (1990) and Panerai (2006), and the parameters of NBR 9050. Knowledge of the area is enriched by the methodology of the production of space made by Henri Lefebvre in his book 'The production of space' (1974) with these categories: space conceived, perceived and lived. Another key reference of this author it s the book 'The Right to the City' (991), which allowed in-depth reflections on the social function of town. In conclusion, the study finds that to guarantee a minimum access conditions in informal sittlements it´s necessary to know the specifics of their morphology, their relations and urban practices in view of the visitability- experiencebility, describing it as complementary concepts

O Plano Diretor como instrumento de gestão da cidade: o caso da cidade de Fortaleza/CE

According to article 182 of the Brazilian Federal Constitution, cities should perform social function, what brings the concept that the city should be a place for one to live well. For that to happen, it should be well administered by its public managers. However, so that there is a sound administration, one that really performs that social function, there must be, first, an efficient planning. We understand that such a thing occurs when the master plan is the main planning instrument of a city and serves as basis for its administration. We notice, however, that in most of the cities the master plan is formulated as a law that regulates urban planning but that both the population and the government most of the times are not aware of its importance concerning the relevant issues related to municipal administration, such as its relationship with the economy, taxation, the social issue, land use regulation, and, in summary, with all the aspects that constitute and that a municipal government should manage in the best possible way. One also knows that, in general, the attempt of city planning has always been connected to the duration of a mandate and that way public managers many times implement restricted measures aiming to just attain a political-electoral objective and publicizing their administration. That implies actions and works that in some cases have negative impacts or ones that cannot be removed from the cities. This study intends to show that the master plan should be the planning instrument guiding the municipal administration but that, however, what we note is a lack of connection between that instrument and the government guidelines of the municipal managers. In order to study what happens to the cities that have a planning which is not taken into account in its administration, we will use the city of Fortaleza, capital of the State of Ceará as a case study. Historically, in Fortaleza the public managers have seldom decided to administer the city in according to the master plans developed for it. We should emphasize that planning begins in the city quite late and until the current days it is being substituted by temporary measures. Through the analysis of the planning process and of the urban management of the city of Fortaleza, especially the master plans predicted since 1933, we explain that if such plans had been implemented, they could have been important tools for its administration to attain a social function, becoming therefore a place for one to live well
