A sucessão ecológica em ambientes florestais em restauração: estrutura e dinâmica da regeneração natural

Ecological restoration aims to restore the self-sustainability potential of degraded environments. The successional trajectory of areas in restoration may differ from the reference ecosystem on a number of factors, especially the disturbance history of the area and management techniques applied in order to reverse the degradation scenario. In this sense, the objective of this study was to characterize the dynamics of natural regeneration and the structure of the regenerating community in an area of ecological restoration for 25 years on the right bank of the Rio Grande in the Power Station in Camargos that belongs to the Companhia Energetica de Minas Gerais - CEMIG, Nazareno, MG, in order to identify the current state of environmental regeneration. In November 2014, there was the first community inventory of seedlings existing in regeneration subplots (2 x 2 m) within the inclusion criteria (height ≥ 10 cm and DBH <5 cm), divided into 44 subplots (11 plots) in two areas, one area in restoration (REF) and a fragment of native vegetation (FRAG). In October 2015, the second sampling was carried out, in which individuals were resampled and recruits and dead individuals quantified. The parameters abundance, floristic similarity, density, dominance, importance value, equability, richness and diversity were analyzed in both samples. The dynamics was evaluated for the number of individuals and basal area in the period of 2014-2015 and individuals distributed according to height. The history of usage area provoked different behavior between the study environments; the patterns of the FRAG and REF communities along the years allowed the distinction between environments and demonstrated great environmental diversity, with differences in the abundance of species, floristic similarity, richness, diversity, vertical structure and dynamics parameters. In the REF area, there was a considerable increase in the density of individuals along the years and the establishment of different species. In this sense, the evaluation of natural regeneration in REF has shown that resilience is gradually being resumed, a necessary condition to support the potential for environmental self-sustainability. However, given the disturbance history, it can be concluded that the environment moves to an alternative state, which is possibly different from that prior to degradation.

Metodologia para o gerenciamento integrado saudável dos resíduos sólidos da bacia da estrada nova do município de Belém/PA

O presente trabalho tem o objetivo de criar uma metodologia para o Gerenciamento Integrado dos Resíduos Sólidos (GIRS) que associa a prática pertinente ao tema, com programas que envolvam a comunidade, no sentido de manter o meio ambiente limpo e saudável, tendo como cenário o município de Belém, especificamente a Bacia Hidrográfica da Estrada Nova (BHEN). Objetiva também identificar porquê, apesar da BHEN possuir coleta de resíduos e serviços de limpeza realizada pela Secretaria Municipal de Saneamento (SESAN), a mesma permanece, constantemente, suja, principalmente, de lixo e entulho lançados nas vias públicas e canais de drenagem dessa bacia. A pesquisa de campo consistiu de entrevistas com os principais atores desse trabalho, a comunidade da BHEN. Inova no município um modelo de programas de participação da população com o nome de Cidadania e Participação Ativa da Comunidade (CIPAC) propondo 20 programas: Mascote da educação ambiental; Boteco em boteco; Eu amo minha cidade; Alô comunidade; TV SOS “Meio ambiente”; Rádio “Desperta comunidade; Coral e teatro “Reciclar”; Educa móvel; Coleta seletiva nas escolas; O meio ambiente pede carona; Centro de memória; A escola do lixo; Conhecer o lixo; Comunidade nota 10; Futuro verde; Coleta seletiva “porta a porta” Implantação dos LEVs; Criação das unidades básicas ecológicas; Criação da central de reciclagem de entulho; Criação das unidades de triagem de materiais recicláveis; Criação das cooperativas de catadores e carroceiros. Faz uma previsão de investimentos para implantação e manutenção desses programas assim como o retorno do investimento aplicado com a implantação. Como resultado, apresenta um novo modelo, baseado na prática, como sustentação para o estabelecimento de uma política municipal, de acordo com a Lei da Política Nacional de Resíduos Sólidos (PNRS) que tramita no Congresso Nacional. Também foram identificados parâmetros capazes de identificar a inadequação do processo atual de coleta de lixo e dos serviços de limpeza nessa bacia. Esses resultados alcançados permitem concluir que grande parte da população da BHEN não está preparada para aderir a um programa de Gestão de Resíduos Sólidos (GRS), que tenha como ponto de partida o GIRS. O grau de escolaridade e o nível de conhecimento da comunidade não representam obstáculos para isso, mas sim a falta de programas que envolvam a sua participação, a coleta de resíduos e serviços de limpeza urbana corretamente prestados, pois, atualmente, na pesquisa de campo realizada, foram visivelmente reprovados. Finalmente, ainda conclui que somente com a implantação de um GIRS, com apoio do CIPAC o meio ambiente seria consideravelmente beneficiado, mas não resolveria os graves problemas ambientais da BHEN, será necessária a melhoria de todos os sistemas de infra-estrutura urbana nessa importante bacia, para um efeito realmente mais saudável. É importante destacar que, no momento atual, as propostas apresentadas por este trabalho são consideradas bastante oportunas, pois com o inicio da implantação do Programa de Recuperação Urbano-Ambiental da Bacia da Estrada Nova (PROMABEM) pela Administração Municipal financiado pelo Banco Interamericano de Desenvolvimento (BID), os problemas sanitários e ambientais dessa importante bacia têm grande probabilidade de ser resolvidos.

Adequação curricular: alternativas de suporte pedagógico na Educação Inclusiva

The organization of the inclusive education is a slow and complex process, which has the necessity of investments in supports for all the scholar team. Aiming at spreading one of the actions carried out for the promotion of the inclusive educational practices in a municipal education system in a western city in the state of São Paulo, this paperwork has the objective of presenting an elaborated manual of orientations for the implementation of the individual curricular adaptations (ACIs) for students who demand special educational necessities (NEEs). The material was constituted on the basis of three data sets: 1) tabulation of the evaluations of the curricular adaptations already made; 2) the literature review; 3) analysis of the themes which have emerged during case discussion meetings mediated by the researchers with teachers from the Specialized Pedagogical Support Service (SAPE), with teachers and administrators from the common education system and the technical-pedagogical team. The final version of the manual contemplates the theoretical-operational aspects about the themes: flexibility and curricular adequation, inclusive education, definitions of NEEs, how SAPE works; and it finishes with a model proposal of ACI. It is expected that the spreading of this material can subside new curricular propositions for students with deficiency that are very distant from the academic level expected for the current scholar year.

Tecnologias de captação e aproveitamento de água de chuva para residências uni familiares

Water scarcity is becoming an increasing problem and more evident worldwide, rainwater utilization is characterized for being one of the simplest and cheapest solutions to preserve drinking water and is a known alternative technology and used to promote sustainability in buildings and reducing pressure on surface waters, it would also reduce runoff and can minimize flooding. The rainwater, while not potable may be used in potable water usage activities, and may thus saving 30 to 40% of potable water. In this work one can see the importance of the capture and use of rainwater (CAAC), bringing economy, to reduce consumption of potable water, reducing the problem of water shortage, and which methods and materials needed to cause its implementation. The work also promoted the characterization of rainwater in the city of Guaratinguetá (SP) and studied its potential use in public housing, calculating the volume needed for implementation of the tank and the cost to implement all rainwater utilization system, but because it is a region with a median rainfall index and the popular houses present an area of small water capitation, the result was not satisfactory. The cost for implementation was high and the financial return was well above average. The government should encourage and support more CAAC, as not thinking about the financial side is advisable to be widespread throughout the country, the benefits it can bring

Relationship Between Oral Health-Related Quality of Life, Oral Health, Socioeconomic, and General Health Factors in Elderly Brazilians

Objectives To assess the impact of oral health on quality of life in elderly Brazilians and to evaluate its association with clinical oral health measures and socioeconomic and general health factors. Design Cross-sectional study. Setting Population-based cohort study on health, well-being, and aging. Participants Eight hundred fifty-seven participants representing 588,384 community-dwelling elderly adults from the city of Sao Paulo, Brazil. MeasurementS Self-perceived impact of oral health on quality of life was measured using the Geriatric Oral Health Assessment Index (GOHAI), with scores categorized as good, moderate, or poor, indicating low, moderate, and high degrees of negative impact on quality of life, respectively. Results Nearly half of the individuals had good GOHAI scores (44.7% of overall sample, 45.9% of dentate participants, and 43.4% of edentulous participants). In the overall sample, those with poor self-rated general health and a need for dental prostheses were more likely to have poor and moderate GOHAI scores. Individuals with depression were significantly more likely to have poor GOHAI scores. No socioeconomic variables were related to the outcome, except self-perception of sufficient income, which was a protective factor against a poor GOHAI score in dentate participants. Conclusion Moderate and high degrees of negative impact of oral health on quality of life were associated with general health and clinical oral health measures, independent of socioeconomic factors.

Proteomics-driven approach for the detection of breast cancer biomarkers

Breast cancer (BC) is the most often diagnosed cancer entity of women worldwide. No molecular biomarkers are usable in the clinical routine for the early detection of BC. Proteomics is one of the dynamic tools for the successful examination of changes on the protein level. In this thesis different proteomics-based investigations were performed for the detection of protein and autoantibody biomarkers in serum samples of BC and healthy (CTRL) subjects. First, protein levels of candidates from previous profiling studies were investigated via antibody-microarray platform. Three proteins were found in distinct levels in both groups: secretoglobin family 1D member 1, alpha-2 macroglobulin and inter-alpha-trypsin inhibitor heavy chain family member 4. The second part was dedicated to the de novo exploration of potentially immunogenic tumor antigens (TA’s) with immunoprecipitation and Western immunoblotting followed by identification over mass spectrometry. Autoantibody levels were verified in individual serum profiling via the protein microarray platform. Two autoantibody’ cohorts (anti-Histone 2B and anti-Recoverin) were found in different levels in both groups. The findings of this PhD thesis underline deregulated serum protein and autoantibody levels in the presence of BC. Further investigations are needed to confirm the results in an independent study population.

Funktionelle Analyse von intrazellulären Signalwegen bei der Migration der embryonalen peripheren Gliazellen von Drosophila melanogaster

Im Rahmen dieser Arbeit wurden Signalwege untersucht, die an der Migration der embryona-len peripheren Gliazellen (ePG) beteiligt sind. Der Fokus lag dabei auf Myoblast city (Mbc). Zunächst wurden dazu unterschiedliche mbc Mutanten analysiert, bei denen es zu starken glialen Migrationsdefekten kommt. Um die auftretenden Phänotypen quantitativ zu analysieren, wurde eine Methode entwickelt um die Position der Pionierglia ePG9 zu bestimmen. Dies ermöglicht es, auch sehr subtile gliale Migrationsphänotypen zu detektieren. Durch knock-down Experimente konnte gezeigt werden, dass Mbc eine zellautonome Rolle bei der glialen Migration spielt. Besonders interessant ist die Tatsache, dass während der Migration der ePG eine alternativ gespleißte Isoform benötigt wird, die bisher kaum untersucht wurde. Durch Strukturvorhersagen konnte gezeigt werden, dass sich der Bereich in dem sich die beiden Isoformen unterscheiden, in einer Region liegt, die sich zu HEAT-repeats faltet. Mbc-PB scheint somit über einen Bereich zu verfügen, der im Vergleich zu Mbc-PA, zusätzliche Interaktionen erlaubt. Zudem scheint es mehrere Phosphorylierungsstellen zu geben, die für die Inaktivierung von Mbc-PB notwendig sind. Die Kinase Wallenda konnte als Kandidat identifiziert werden, der für die Phosphorylierung von Mbc-PB verantwortlich ist. Weitere Experimente zeigten eine einen zellautonomen Einfluss von Mbc-PB auf ePG7, die indirekt die Migration der Pionierglia ePG9 beeinflusst.

Self-Immolation In Tibet: Beyond The Lens Of The Western Media

This thesis provides a critique of Western media articles concerning self-immolation in Tibet. I begin by illustrating how the Western media provides reductionist accounts of Tibetan self-immolation by depicting the act solely as a form of political protest in response to Chinese occupation. I argue that these limited portrayals of self-immolation can be attributed to the Shangri-La imagery that characterizes much of the Western conceptions of Tibet. Through Shangri-La imagery, both Tibetans and their Buddhist religion are portrayed as utopic, peaceful, and able to provide the antidote to solving Western problems relating to modernization and consumerism. After illustrating the ways in which Shangri-La imagery influences Western media portrayals of Tibetan self-immolation, this thesis explores the commonly disregarded Buddhist dimensions of the act. Looking to Buddhist doctrine, scripture, and history, this thesis establishes a clear relationship between self-immolation and Buddhism, which situates the act as being more complicated than mere political protest. I argue that these limited portrayals given by the Western media are problematic because they overlook a fundamental aspect of self-immolation, thus potentially misrepresenting Tibetans. This thesis explores the Buddhist dimensions of self-immolation as a possible way to further understand what has led more than one hundred Tibetans to perform this act during the time of political crisis.

DtpB (YhiP) and DtpA (TppB, YdgR) are prototypical proton-dependent peptide transporters of Escherichia coli

The genome of Escherichia coli contains four genes assigned to the peptide transporter (PTR) family. Of these, only tppB (ydgR) has been characterized, and named tripeptide permease, whereas protein functions encoded by the yhiP, ybgH and yjdL genes have remained unknown. Here we describe the overexpression of yhiP as a His-tagged fusion protein in E. coli and show saturable transport of glycyl-sarcosine (Gly-Sar) with an apparent affinity constant of 6.5 mm. Overexpression of the gene also increased the susceptibility of cells to the toxic dipeptide alafosfalin. Transport was strongly decreased in the presence of a protonophore but unaffected by sodium depletion, suggesting H(+)-dependence. This was confirmed by purification of YhiP and TppB by nickel affinity chromatography and reconstitution into liposomes. Both transporters showed Gly-Sar influx in the presence of an artificial proton gradient and generated transport currents on a chip-based sensor. Competition experiments established that YhiP transported dipeptides and tripeptides. Western blot analysis revealed an apparent mass of YhiP of 40 kDa. Taken together, these findings show that yhiP encodes a protein that mediates proton-dependent electrogenic transport of dipeptides and tripeptides with similarities to mammalian PEPT1. On the basis of our results, we propose to rename YhiP as DtpB (dipeptide and tripeptide permease B), by analogy with the nomenclature in other bacteria. We also propose to rename TppB as DtpA, to better describe its function as the first protein of the PTR family characterized in E. coli.

Community managed rural water supply systems in the Dominican Republic : assessment of sustainability of systems built by the National Institute of Potable Water and Peace Corps, Dominican Republic

In the Dominican Republic economic growth in the past twenty years has not yielded sufficient improvement in access to drinking water services, especially in rural areas where 1.5 million people do not have access to an improved water source (WHO, 2006). Worldwide, strategic development planning in the rural water sector has focused on participatory processes and the use of demand filters to ensure that service levels match community commitment to post-project operation and maintenance. However studies have concluded that an alarmingly high percentage of drinking water systems (20-50%) do not provide service at the design levels and/or fail altogether (up to 90%): BNWP (2009), Annis (2006), and Reents (2003). World Bank, USAID, NGOs, and private consultants have invested significant resources in an effort to determine what components make up an “enabling environment” for sustainable community management of rural water systems (RWS). Research has identified an array of critical factors, internal and external to the community, which affect long term sustainability of water services. Different frameworks have been proposed in order to better understand the linkages between individual factors and sustainability of service. This research proposes a Sustainability Analysis Tool to evaluate the sustainability of RWS, adapted from previous relevant work in the field to reflect the realities in the Dominican Republic. It can be used as a diagnostic tool for government entities and development organizations to characterize the needs of specific communities and identify weaknesses in existing training regimes or support mechanisms. The framework utilizes eight indicators in three categories (Organization/Management, Financial Administration, and Technical Service). Nineteen independent variables are measured resulting in a score of sustainability likely (SL), possible (SP), or unlikely (SU) for each of the eight indicators. Thresholds are based upon benchmarks from the DR and around the world, primary data collected during the research, and the author’s 32 months of field experience. A final sustainability score is calculated using weighting factors for each indicator, derived from Lockwood (2003). The framework was tested using a statistically representative geographically stratified random sample of 61 water systems built in the DR by initiatives of the National Institute of Potable Water (INAPA) and Peace Corps. The results concluded that 23% of sample systems are likely to be sustainable in the long term, 59% are possibly sustainable, and for 18% it is unlikely that the community will be able to overcome any significant challenge. Communities that were scored as unlikely sustainable perform poorly in participation, financial durability, and governance while the highest scores were for system function and repair service. The Sustainability Analysis Tool results are verified by INAPA and PC reports, evaluations, and database information, as well as, field observations and primary data collected during the surveys. Future research will analyze the nature and magnitude of relationships between key factors and the sustainability score defined by the tool. Factors include: gender participation, legal status of water committees, plumber/operator remuneration, demand responsiveness, post construction support methodologies, and project design criteria.

Television viewing, C-reactive protein, and depressive symptoms in older adults

There is emerging evidence for a link between sedentary behavior and mental health, although the mechanisms remain unknown. We tested if an underlying inflammatory process explains the association between sedentary behavior and depressive symptoms. We conducted a two year follow-up of 4964 (aged 64.5 ± 8.9 years) men and women from the English Longitudinal Study of Ageing, a cohort of community dwelling older adults. Self-reported TV viewing time was assessed at baseline as a marker of leisure time sedentary behavior. The eight-item Centre of Epidemiological Studies Depression (CES-D) scale was administered to measure depressive symptoms at follow-up. At baseline, TV time was associated with C-reactive protein (CRP), adjusted geometric mean CRP values were 2.94 mg/L (<2 h/d TV); 3.04 mg/L (2–4 h/d TV); 3.29 mg/L (4–6 h/d TV); 3.23 mg/L (>6 h/d TV). We observed both a direct association of TV time on CES-D score at follow-up (B = 0.08, 95% CI, 0.05, 0.10) and indirect effects (B = 0.07, 95% CI, 0.05, 0.08). The indirect effects were largely explained through lack of physical activity, smoking, and alcohol, but not by CRP or body mass index.

Critical Essays on "Causation & Responsibility"

Due to its scope and depth, Moore’s Causation and Responsibility is probably the most important publication in the philosophy of law since the publication of Hart’s and Honoré’s Causation in the Law in 1959. This volume offers, for the first time, a detailed exchange between legal and philosophical scholars over Moore’s most recent work. In particular, it pioneers the dialogue between English-speaking and German philosophy of law on a broad range of pressing foundational questions concerning causation in the law. It thereby fulfills the need for a comprehensive, international and critical discussion of Moore’s influential arguments. The 15 contributors to the proposed volume span the whole interdisciplinary field from law and morals to metaphysics, and the authors include distinguished criminal and tort lawyers, as well as prominent theoretical and practical philosophers from four nations. In addition, young researchers take brand-new approaches in the field. The collection is essential reading for anyone interested in legal and moral theory.
