Efeitos de fungicidas alternativos em folhas de Carthamus tinctorius L. (Asteraceae), potencial espécie para cultivo em agricultura familiar

The currently main development model on global society is driven by an economic rationality that endangers the environment and social justice. More and more, attention to this way of production and consumption is increasing, boosting research for sustainable development, with an environmental rationality that can harmonize nature preservation and welfare of all socioeconomic classes. One of the efforts on this sense is changing the sources supplying the energy demand, replacing fossil fuels for renewable and cleaner sources, such as biofuels. Carthamus tinctorius (safflower) is an oilseed crop with potential for biodiesel production, with good oil yield and chemical profile, allied to good adaptation to climates such like the northeastern semiarid lands of Brazil. With public policies fomentation, the use of this species may be an interesting alternative for family farming. In farming in general, the use of pesticides to prevent and combat diseases and plagues is common, which is not a sustainable practice. Thus, there are researched alternative, less dangerous substances. In this study, it was aimed to assess if neem (Azadirachta indica) leaf extract (20% m/v) and Bordeaux mixture (copper sulfate) have effects on safflower. It was also aimed to verify acceptance of farmers on safflower crop in Apodi, a municipality in Rio Grande do Norte state, Brazil, in view of it being localized in the aimed region for this crop cultivation. Besides that, understanding that the farmers’ knowledge and inclination to adopt the crop is fundamental for the introduction of this species and socioeconomic growth due to its exploration. In addition, a booklet with basic information on safflower was produced. In the field experiment, the fungicides were pulverized on plants cultivated in field experimental plots, with collection of leaf samples for analysis on anatomy, cuticle, and epicuticular wax morphology, the protective layer that interfaces with the surrounding ambient. In Apodi, forty-five farmers from Potiguar Cooperative of Apiculture and Sustainable Rural Development (COOPAPI) underwent semi-structured interviews, which also addressed their assessment on currently cultivated crops and perception of pesticide uses and sustainable alternatives. After comparing using analysis of variance, it was found that there was no difference between treatments in the experiment, as well as no anatomical or morphological modifications. Safflower acceptation among farmers was wide, with 84% of interviewees believing in a perspective of good incomes. The current scenario, comprised of low crop diversity, fragile in face of droughts and plagues, can partially explain this opinion. The booklet was effective in catching people attention for the species potential. There was wide acknowledgement on the importance of alternative pesticides, justified by health security. Based on the assessed parameter in the results of this research, the treatments here utilized may be recommended as fungicides for safflower. Given the crop susceptibility to fungi in heavy rainy period, it is advised that its potential introduction on the region shall be focused on semiarid areas.

Processos criativos com alunos-atores idosos: caminhos de uma dramaturgia de pertencimento

The present work is to present an experience artistic and pedagogical means of a laboratory-developed with senescent students from their memory files. Unlike other works developed with students of the third age, we make use of the archives of memory, where the drama takes from improvisations developed memories, in other words, the text is built not just recollected by students. Our work, however, is built by a look from the outside. The affective memories narrated by students serve as an engine for text construction and spectacle titled Vamos Falar de Amor. In this experiment the teacher-director also becomes an dramaturgista, and uses her imagination, that also comes filled with her own memories, in order to complete the gaps of the narrative, in a hybrid process in which the collective memory interlace the individual memory, transforming epic into dramatic. Here the route designed to get to the construction of the text and left the text for the second scripture, the spectacle. We want to show that old age is comprised of various hues, and that this phase of human development brings aspects that differ from old to old, and that education and theater can be a resumption of the social role of the elderly in contemporary surroundings. Therefore, the dramaturgy of memory creates the dramaturgy of belonging, facilitating in many aspects the Scenic Play with the elderly ones.

Direitos fundamentais sociais no Brasil: desafios e mecanismos para sua concretização

The work referred to above, in order to contribute to the legal issues, economic, political and social of the violation of social rights, performs even firmer approach to various implementation mechanisms of social rights in Brazil. Therefore, it begins the study dealing with aspects and important characters of the rights under discussion, as its normative forecast, concept, classifications; respect of social rights with the existential minimum; the principle of reservation of the possible and the need to use this principle as optimization commandment of state resources and the deficit of the realization of social rights in the country. This, in later chapters, in an interdisciplinary approach, challenges and proposals for the realization of social rights by bringing in each chapter, mechanisms for such implementation. That way, as a general objective, it has been to contribute to the discussed problems, when present proposals for the realization of social rights in the Brazilian context. As specific objectives, as well as record the key aspects of the rights in allusion, the one has to promote the perspective of economic development and taxation as posts instruments that the State must be focused on the promotion of social rights by registering in this context that nonexistent economic development without reducing poverty, misery and social inequality and adding that there should be a directly proportional relationship between the tax burden in the country and the human and social development index; analyze the achievement of budget control as essential and healthy measure for the realization of social rights; highlight the importance of society to the achievement of unavailable social interests, affirming the need for the implementation of participatory democracy and, in this line, brings knowledge of the Constitution and the constitutional sense as elements that provide the constitutional progress. Finally, it presents a study on public policies, considering that these are equivalent to the primary means of the promotion of social rights. That way it analyzes the stages that integrate public policies, ranging from the perception of social problems for evaluation and control of the policies implemented; debate about the administrative discretion in when it comes to public policies; brings the classification of essential public policies, the relationship of these with the existential minimum, control parameters and, finally, the legalization of public policy, regarded as legitimate to remedy the unconstitutional state failure and give normative effectiveness and strength to the defining constitutional rules for fundamental social rights. It uses to achieve the objectives outlined, the bibliographic and normative approach method and performs an analysis of jurisprudence related understandings to matter. In the conclusions, it rescues the most important aspects elucidated at work, with the aim of giving emphasis to the proposals and mechanisms that contribute to the solution of the discussed problems.

John Stuart Mill e o cultivo da individualidade

The development of a human individual was a matter of investigation for many thinkers through the history of philosophy. The meanings that this development has taken were, nevertheless, very diversified, involving moral, political, epistemological, aesthetical and even religious aspects. The main agents in this process of development of human individuality are, on the one hand, each individual, who has to strive to improve himself the most, creating and resorting to the means available to that; on the other hand, the fomentalist State also have to take his part in this process, given that such a State has a direct interest in the development of his own citizens; it has to act in such a way that it can foment new and enhance the old existing means that can be used to accomplish the task of developing the human individuality. The goal of this thesis is to investigate the meaning that such development has acquired for the utilitarian philosopher John Stuart Mill, from his conception of individuality.

Determinação da condutividade do solo para agricultura: uma metodologia utilizando propagação de ondas AM

Agriculture is an essential activity to the human development, the tendency is that their need to increase according to the increase in world population. It is very important to take the maximum performance that is possible of each land without degrading it, a frequently monitoring is essential for the best performance. The purpose of this work is, nondestructively, to monitor the surface electrical conductivity of the soil in a demarcated area, as on a plantation, using low frequency radio waves. The conductivity is directly linked to the amount of water in the area and nutrients, therefore a periodic or even permanent monitoring increases significantly the efficient of the use of the soil. They will be used long-wave radio transmission or medium whose main characteristic to spread over the surface of the earth. It is possible to choose an AM radio with location, frequency and power of the transmission known or generate the signal. The studied method computes the conductivity of the ground in a straight line between two measured points, so it can be used in smaller or larger size fields. Measurements were carried out using an electromagnetic field strength analyzer. The data obtained in the measurements are processed by a numerical calculation program, in our case Matlab. It is concluded that the recommendations of the ITU (International Telecommunication Union) on the conductivity of soil in Brazil is far from reality, on some routes the recommendations indicate the use of the electrical conductivity of the soil 1 mS/m, while the measurements was found 19 mS/m. With the method described a precision farmer, once initial research for about a year, can monitor the humidity and salinity of the land, with the ability to predict the area and the most suitable time for irrigation and fertilization, making management more efficient and less expensive, while optimizing water use, natural resource increasingly precious.

Governança metropolitana e sustentabilidade: uma análise da gestão dos resíduos sólidos em Natal e Parnamirim

Nowadays the rapid growth of urban centers, the accumulation of social and environmental demands, the relationship between public policy and increasingly complex problems accentuates the feeling that cities undergo an urban crisis. This crisis is especially characterized by its multidimensionality, which goes through economic, cultural, ethical, environmental and, above all, political issues. In order to study the core of this crisis that is manifested by the urbanization process and has in its exacerbation on the metropolitan areas was conducted conceptual and theoretical study of the meaning of sustainable development applied to the everyday reality of cities, extracting from this debate concepts, such as: sustainable territorial development, administrative sustainability and political sustainability. Looking forward to test this the practical applicability of these theoretical concepts studied, an empirical study was done on the reality of metropolitan solid waste in Natal, Rio Grande do Norte, Brasil. According to the recent theoretical debate, the waste comprises a sector of the urban environmental crisis that best represents the relationship between man and environment. Ensuring the multidimensionality of environmental issues through the “Saber Ambietal” (LEFF, 2005), was made a extensive qualitative study correlating the concepts of sustainable territorial development, metropolitan governance and “Saber Ambiental” applied on solid waste. The results point to the real challenges of municipal government in understanding the real situation, take action and change the inertia in which have operated in recent decades. The results also showed the importance of transforming environmental issues in political, in other words, struggle for ideas, ideological and ethical references.

Aids em idosos no Brasil no período de 2000 a 2012: uma análise de série temporal e dos fatores contextuais associados

The characteristics profile of individuals who develop AIDS in Brazil has changed over time. Among these modifications, a worrying finding is the increased incidence of AIDS in the elderly across the country. But, however, is not yet clear whether the increase in AIDS cases is sufficient to produce a change in the trend of measures in recent years in the Brazilian states, and this increase has an effect from the socioeconomic and demographic indicators. In this sense, the objective of this study is to analyze the AIDS incidence rates among the elderly in Brazil and its effect on socioeconomic and demographic inequalities in the period 2000 to 2012. This is an ecological time-series study to meet behavior of the time series of the incidence rates of AIDS in the elderly from 2000 to 2012. the rates were calculated using the secondary data from Diseases Information System Notification and the Brazilian Institute of Geography and Statistics. Data were analyzed statistically to know the trends in incidence rates, by polynomial regression model and joinpoint log-linear regression model, but also the simple linear regression analysis to find the relationship of trends with variables socioeconomic and demographic. SPSS 20.0® and Joinpoint 4.1.1 programs were used. All tests were carried out considering a significance of 5%. After the analysis, in Brazil were reported 62,052 new cases of AIDS in the elderly from 2000 to 2012. During this period, a significant increase was found for males, both aged 50-59 years (APPC: 3.46 %, p <0.001), such as above 59 years (AAPC: 4.38%; p <0.001). For females, the increase was significant and has the largest increments in the time series, when compared to males in both age groups (AAPC: 4.62%, p <0.001 and AAPC: 6.53%; p <0.001) respectively. The largest increases are observed in women and in the states of North and Northeast. In the Southeast Region is observed stabilization of rates throughout the series. The reason of trends between the sexes had a significant reduction, but also an approach in both age groups of the study, reaching a ratio of 1.7 males for every female in the youngest age group. The trends were related to illiteracy rates, with increasing social inequality and the lowest human development in the Brazilian states. We conclude that in Brazil the incidence of AIDS in the elderly follows an increasing trend in individuals over 50 years. Noteworthy are the highest rates of study in women and in the states of North and Northeast. In this sense, the country needs to enhance policies towards older people with STD / AIDS, training health professionals and developing effective measures for the prevention and early diagnosis of infected people, especially in places with limited resources and high social inequality. In the long term, it is developing new studies to understand whether the measures taken were effective in reducing the trends identified in this study.

Modelagem e análise dinâmica de um sistema de conversão de energia eólica dotado de gerador síncrono de imã permanente utilizando a plataforma ATP

Human development requires a broad balance between ecological, social and economic factors in order to ensure its own sustainability. In this sense, the search for new sources of energy generation, with low deployment and operation costs, which cause the least possible impact to the environment, has been the focus of attention of all society segments. To do so, the reduction in exploration of fossil fuels and the encouragement of using renewable energy resources for distributed generation have proved interesting alternatives to the expansion of the energy matrix of various countries in the world. In this sense, the wind energy has acquired an increasingly significant role, presenting increasing rates of power grid penetration and highlighting technological innovations such as the use of permanent magnet synchronous generators (PMSG). In Brazil, this fact has also been noted and, as a result, the impact of the inclusion of this source in the distribution and sub-transmission power grid has been a major concern of utilities and agents connected to Brazilian electrical sector. Thus, it is relevant the development of appropriate computational tools that allow detailed predictive studies about the dynamic behavior of wind farms, either operating with isolated load, either connected to the main grid, taking also into account the implementation of control strategies for active/reactive power generation and the keeping of adequate levels of voltage and frequency. This work fits in this context since it comprises mathematical and computational developments of a complete wind energy conversion system (WECS) endowed with PMSG using time domain techniques of Alternative Transients Program (ATP), which prides itself a recognized reputation by scientific and academic communities as well as by electricity professionals in Brazil and elsewhere. The modeling procedures performed allowed the elaboration of blocks representing each of the elements of a real WECS, comprising the primary source (the wind), the wind turbine, the PMSG, the frequency converter, the step up transformer, the load composition and the power grid equivalent. Special attention is also given to the implementation of wind turbine control techniques, mainly the pitch control responsible for keeping the generator under the maximum power operation point, and the vector theory that aims at adjusting the active/reactive power flow between the wind turbine and the power grid. Several simulations are performed to investigate the dynamic behavior of the wind farm when subjected to different operating conditions and/or on the occurrence of wind intensity variations. The results have shown the effectiveness of both mathematical and computational modeling developed for the wind turbine and the associated controls.

O Projeto Sete Villas

A crescente valorização dos recursos patrimoniais tem adotado uma importância particular nas últimas décadas, especialmente no que diz respeito às áreas rurais. Estas áreas são vítimas de processos de descaracterização devido à ausência de dinamismo económico e à consequente perda significativa de população. A conceção de novas estratégias implica um conhecimento aprofundado do potencial endógeno destes territórios para que seja possível perceber até que ponto os elementos da paisagem e o seu substrato natural podem ser entendidos e valorizados patrimonialmente, contribuindo desta forma para o desenvolvimento local sustentável através do aproveitamento turístico. Apesar de nos últimos anos ter sido verificado um crescente interesse pelas áreas rurais, tanto para viver como para visitar, ainda persiste uma imagem negativa destes territórios. E é necessário, portanto, pensar imagens de marca fortes e coerentes que apostem no carácter diferenciador destes espaços. O objetivo desta investigação passa pela avaliação da importância que o marketing territorial pode representar no desenvolvimento de pequenos territórios com potencialidades culturais. Estas constituem uma estratégia de promoção destes locais, contribuindo significativamente para o desenvolvimento dos próprios territórios, uma vez que para o aumento da atratividade territorial poderá induzir a um maior investimento e a um maior número de visitantes. A área de estudo selecionada para uma avaliação mais aprofundada será a região do Alentejo, que desembocará num projeto cultural criativo com ênfase no distrito de Portalegre. Este Projeto tem como fundo de base, a promoção turístico-cultural de um conjunto de pequenas vilas tradicionais pertencentes ao distrito, agrupando as mesmas numa rede coletiva de identidade comum. Este processo exige um estudo elaborado no que diz respeito aos recursos de vertente e potencialidade cultural destes territórios de modo a que consigamos transformá-las numa nova imagem de marca. Mais importante que o próprio património material e imaterial já previamente reconhecido são as pequenas narrativas locais que nos esclarecem quanto à sua história e identidade dos próprios residentes. O produto final será a construção de uma nova rede turístico-cultural que agrupe estas pequenas vilas num só roteiro. Para tal, é necessária a construção de um guia cultural criativo, onde a nova imagem destes locais se constrói pelas pequenas histórias e narrativas de interesse cultural. Na prática este produto será concretizado de três formas, impresso, online, e sob a forma de uma aplicação para mobile phone.

Mortalidade por câncer de boca e condição sócio-econômica no Brasil

Chronic non-communicable diseases represent a major public health problem, requiring more effective investigation and control by government agencies. The aim of this study was to correlate the mortality rate for oral cancer in Brazilian State capitals from 1998 to 2002 with socioeconomic factors collected in the 2000 census, using an ecological study design. Data were obtained from the Mortality Information System from 1998 to 2002. Social factors were taken from the Brazilian Human Development Atlases. After data collection, statistical analysis was performed using Pearson's correlation index. The findings included positive and significant correlations among the socioeconomic indicators (Municipal Human Development Index - MHDI, MHDI-income, MHDI-education, MHDI-life expectancy, and per capita income), and negative and significant correlations with the socioeconomic indicators Gini Index and infant mortality. Despite the study’s limitations and probable underreporting in less developed State capitals, the study found significant statistic correlations between the selected socioeconomic indicators and the oral cancer mortality rate___________________________RESUMO As doenças crônico-degenerativas representam um grande problema de saúde pública, necessitando de levantamento e controle mais efetivos destas enfermidades por parte dos órgãos públicos. O objetivo deste estudo foi correlacionar os índices de mortalidade por câncer oral nas capitais do Brasil no período de 1998 a 2002 com indicadores sócio-econômicos do Censo Demográfico de 2000 , por meio de um estudo do tipo ecológico. Os dados foram extraídos do Sistema de Informação de Mortalidade (Ministério da Saúde/DATASUS), para os anos de 1998-2002. Os indicadores sócio-econômicos foram obtidos a partir do Atlas do Desenvolvimento Humano no Brasil. Após coleta dos dados, a análise estatística foi realizada usando-se o índice de correlação de Pearson. Observaram-se corre- lações positivas e significativas entre os indicadores sócio-econômicos (Índice de Desenvolvimento HumanoMunicipal – IDH-M, IDH-M renda, IDH-M educação, IDH-M longevidade e renda per capita), e correlação negativa e significante para os indicadores sócio-econômicos índice de Gini e mortalidade infantil. Apesar das limitações do estudo e da provável problemática de sub-registros nas capitais menos desenvolvidas, o presente trabalho encontrou correlações estatisticamente significantes entre os indicadores sócio-econômicos selecionados e o índice de mortalidade por câncer oral

Diferenças de Sexo nos Hábitos/Comportamentos Alimentares e Sintomas de Perturbações do Comportamento Alimentar, numa Amostra de Adolescentes

Introdução: A adolescência é um dos períodos mais desafiadores no desenvolvimento humano. As alterações que ocorrem a diferentes níveis (e.g. físicas) geram repentinas mudanças na perceção do eu, incluindo na perceção da imagem corporal, além de criarem necessidades nutricionais especiais. A literatura reconhece que existem diferenças importantes na prevalência, sintomatologia específica de perturbação do comportamento alimentar (PCA) e hábitos/comportamentos alimentares por sexo, mas ainda poucos estudos em Portugal, abordaram esta temática. Assim, são nossos objetivos, considerando separadamente os rapazes e raparigas de uma amostra de adolescente: 1) verificar a prevalência de diferentes hábitos/comportamentos alimentares; 2) apurar a prevalência de sintomas específicos de perturbação do comportamento alimentar (PCA), avaliados através dos itens de um questionário que avalia atitudes alimentares, associadas às PCA, o Teste de Atitudes Alimentares (TAA-25); 3) verificar a prevalência de jovens que apresenta pontuação superior/igual a 19 no TAA-25, indicadora de eventual PCA e 4) averiguar a prevalência das diferentes categorias de índice de massa corporal (IMC) (magreza, peso normal, excesso de peso e obesidade). Pretendemos, também, explorar associações entre a variável sexo e diversas variáveis: 1) o IMC categorizado; 2) as dimensões do TAA-25 e o IMC (enquanto variável contínua); 3) a pontuação do TAA-25 dicotomizada pelo ponto de corte de 19; 4) itens relativos aos hábitos/comportamentos alimentares e 5) itens individuais do TAA-25. A título exploratório, pretendemos, ainda, verificar eventuais associações entre diferentes sociodemográficas e os itens que avaliam hábitos/comportamentos alimentares. Métodos: A nossa amostra é constituída por 308 adolescentes (M = 14,5 anos DP = 1,67; raparigas, n = 184, 59,7%). Todos preencheram um protocolo composto por um questionário sociodemográfico e pelo Teste de Atitude Alimentares-25/Eating Attitudes Test-25. Resultados: Não se encontraram associações estatisticamente significativas entre a variável sexo e as variáveis IMC categorizado, dimensões do TAA-25, IMC, TAA-25 (categorizado pelo ponto de corte de 19) e os itens que avaliam hábitos/comportamentos alimentares. Porém, alguns itens particulares do TAA-25 revelaram uma associação significativa com o sexo. Relativamente TAA-25 dicotomizado segundo o ponto de corte 19 verificou-se que em ambos os sexos, a grande maioria dos jovens apresenta uma pontuação abaixo desse ponto de corte. Quanto aos itens que avaliam hábitos/comportamentos alimentares e as variáveis sociodemográficas e familiares, a frequência com que os jovens bebem refrigerantes e ingerem vegetais mostraram-se estatisticamente associadas à escolaridade do pai. Igualmente, a frequência com que ingerem vegetais e com que ingerem fast food também se mostraram estatisticamente associadas à zona da escola que frequentam. Discussão: No geral, na nossa amostra, os hábitos/comportamentos alimentares dos adolescentes não são tão negativos como os relatados por alguma literatura (e.g. percentagem elevada de jovens que “salta” o pequeno almoço). Igualmente, não parecem existir diferenças significativas de sexo quanto às atitudes alimentares, eventual PCA, IMC e hábitos/comportamentos alimentares. No entanto, existem diferenças de sexo em alguma da sintomatologia específica avaliada pelo TAA-25. É bom verificar que ambos os sexos revelam uma prevalência baixa de eventual PCA, embora as raparigas revelam um valor superior. Algumas variáveis sociodemográficas revelam associações com os hábitos/comportamentos alimentares. As implicações dos resultados encontrados são discutidas pela autora.
