Prazer com razão: análise e crítica da ética sexual Kantiana

This work aims to present the foundations of Kantian ethics concerning to moral judgments about sexual practices. It shows that the sexual act, for the philosopher, inevitably degrades individuals who are taking part of it, given its objectifying nature, manifested in the usage of individuals as mere means to obtain pleasure. To solve this quandary of nature since humanity is an end in itself, by the virtue of being bearer of rationality and cannot, therefore, be treated as mere means Kant claims that marriage is morally the appropriate locus for the exercise of sexuality, given the reciprocity forged there, preventing degradation. In marriage, the bond established between the impulse of nature to the conservation of the species achieved through the sexual intercourse opened to procreation and the duty of man in regarding himself as an animal being preserving the species without degrading the person is accomplished in a fully moral way. This text clarifies that the justification for the assumption of this solution is fixed at two developments of the categorical imperative: the formulas of the law of nature and humanity. Despite the fact the first brings significant contributions to human relations through the concept of reciprocity, the second establishes a normative role for the teleological argument of sexuality, becoming an obstacle in kantian's practical philosophy. To overcome that obstacle, we outline a critics which relies on the studies of Michel Foucault about sex and the power techniques related to them, producer of a scientia sexualis in the Western, demonstrating that the moral of the philosopher from Königsberg is also present in this project somehow. Finally, in a foucaultian's reading of kantian Aufklärung, we recognize that, to propose new ethical possibilities of the experience of sexuality, it is necessary to think and create new relational spaces in which the subject takes autonomously the government of self.

DINÂMICAS MERCANTIS COLONIAIS : Capitania do Rio Grande do Norte (1760-1821)

The size and dynamics of the market producer, consumer and exporter of the Captaincy of Rio Grande do Norte, in the period between 1760 and 1821 is the primary goal of this dissertation. In order to establish relations between the founding of new towns built from 1750 and its incorporation into the water supply and domestic market, showing more specifically the colonial economic relations established between the coast and the hinterland of the Province. Based on references by authors such as Edward Shils and Immanuel Wallerstein have investigated topics such as formation of colonial space, deployment-action of colonial institutions regarding business practices, and the dynamic market of the Province of Rio Grande do Norte.

Line-pack management for producing electric power on peak periods

The distribution of natural gas is carried out by means of long ducts and intermediate compression stations to compensate the pressure drops due to friction. The natural gas compressors are usually driven by an electric motor or a gas turbine system, offering possibilities for energy management, one of these consisting in generating energy for use in-plant or to commercialize as independent power producer. It can be done by matching the natural gas demand, at the minimum pressure allowed in the reception point, and the storage capacity of the feed duct with the maximum compressor capacity, for storing the natural gas at the maximum permitted pressure. This allows the gas turbine to drive an electric generator during the time in which the decreasing pressure in duct is above the minimum acceptable by the sink unit. In this paper, a line-pack management analysis is done for an existing compression station considering its actual demand curve for determining the economic feasibility of maintaining the gas turbine system driver generating electricity in a peak and off-peak tariff structure. The potential of cost reduction from the point of view of energy resources (natural gas and electric costs) is also analyzed. (C) 2010 Elsevier Ltd. All rights reserved.

Cooperação em sagüis comuns callithrix jacchus: condições e restrições

The cooperative behavior is no longer a dilemma for the theory of evolution, since there are models that explain the evolution of this behavior by means of natural selection at the individual level. However, there have been few studies on the proximal factors that interfere with cooperative behavior. In the study of the influence of cognition on cooperation, many authors have been interested in situations in which individuals decide whether to act cooperatively and select partners with different qualities to cooperate. Of the factors studied, we highlight the need for understanding the apparatus and communication between partners to the occurrence of cooperation. Recently, highlight is the proposal that the ability to cooperate would be greater in species with cooperative breeding system. Thus, the common marmoset (Callithrix jacchus) is a New World monkey which stands as a valuable species for this type of study because it presents cooperative actions in nature, such as sharing food and protection of the community territory. Our experiment investigated whether common marmosets unrelated females (n = 6) were able to cooperate using an electrical and a mechanical apparatus, if this cooperation is a byproduct of individual actions or involve social attention, if it occurs inter-individual variation in the use of devices and formation of roles (producer / scrounger) in dyads. We use the number of rewards obtained by animals (Ratio of Correct Pulls) as indicators of cooperation and glances for partners (Ratio of Correct Glances) as indicators of social attention and communication. The results indicate that the type of apparatus was not a constraint for the occurrence of cooperation between the marmosets, but still has not been verified formation of roles in the dyads. The performance of animals in the two devices showed a large variation in the learning time, not having relationship with the performance in the tests phase. In both devices the level of social glances at control phases were casually correlated with any other phase, but the data showed that there was not social attention, that is, the monkeys realized that they gave food to the partners, but the partners did

Custos e viabilidade econômica da produção de lambari-do-rabo amarelo em Monte Castelo/SP: um estudo de caso

The aim of this study was to analyze the cost of production and economic viability of production of Lambari in Monte Castelo/SP, with the primary market for the live-bait for sport fishing of carnivorous fish. To calculate the operating cost structure was used the model proposed by the Instituto de Economia Agricola from São Paulo/Brazil. In analyzing the economic viability of investment, we determined the Internal Rate of Return (IRR) and Pay Back Period. It was noted that the inputs represented approximately 74.0% of the EOC (Effective Operating Cost). In the rentability analysis (short term), there was an operating profit of R$ 3,133.45 for a cycle, with a profitability of 18.65% for four months of production, a cost price of R$ 13.02 kg(-1). For viability of the activity (long term), the results were attractive to recovery capital from the 3(rd) year (Pay Back), with an IRR of 25.68% and 89.0% return on the producer in 5 years (BCR - benefit cost ratio). The study of costs and economic viability analysis reinforce the importance of rational management in the productive system and the importance of planning and managing the profitability of the activity.

A experiência de depressão na contemporaneidade: uma compreensão fenomenológico-existencial

The depression is one of the most common forms of getting ill nowaday. Due to the increase in incidence of depression cases registered worldwide, this theme has been the subject of important studies, especially regarding the symptomatological description and biological etiology of the disease. This research had the objective to understand the unique experience of depression experienced by people who recognize themselves in depression, under the focus of existential phenomenology of Martin Heidegger. To reach the proposed objective, individuals narratives interviews were conducted with four participants, starting from the triggering question, "from your experience, how is for you to being depressed?". The survey revealed that depression affects the whole person and is related to stressful life contexts. Depression was narrated as an experience of disempowerment and lack of self esteem and personal worth. The collaborators of the research referred to the depression from sad, angry, bored and pessimistic mood. The time is experienced as a restriction to the projective opening towards the possibilities of being in which the future is seen as catastrophic and the past lived as debt and guilt. The corporeality, in depression is experienced through the weight, fatigue and pains for no reason. The space is lived from the notion of fall and collapse. We also realized the desire for isolation and avoidance of social contact. Suicide is desired and represents the end of the suffering in life. The depression has proved, still, very stigmatized, because it is discredited and misunderstood. The stigma also addressed to the experience of hospitalization and the unsuitability to the socially imposed standards of beauty, which generates enough suffering to the depressed person. The medication was described based on its positive effects, as a balance and suffering reducer, but also as a producer of dependence. Were also identified according to the collaborators, traces of selfdemand, ordenality and being-for-others, characteristic of typus melancholicus. This study contributes to an understanding of the depression that goes beyond the merely biological perspective and symptomatology of the pathology. The investigation of the depressive experience, through the lens of Heidegger's phenomenology, showed us the phenomenon of the depression in their singularity, complexity and multiple meanings, showing the close relationship between the formation of the depression and the context of personal and social life of the participants

O Serviço Residencial Terapêutico: cartografias de um híbrido no contexto da desinstitucionalização em saúde mental

This thesis seeks to uphold the idea that the therapeutic residential service, as hybrid device and recent process of deinstitutionalization in mental health, works as a problem producer while it also indicates challenges and potentialities in this process, the attention on mental health and on its own care production. To that end, we work with the prospect map with which we approach reality as the subjectivities production field which transformations and intensities are the major thought propellants. From this perspective, it was possible to produce three "purpose maps" from meetings with actors and groups involved with the TRS and the theoretical study carried out. On the first map we mapped the conditions of possibility of this device and its design in the midst of the process of institutionalization and health policies. We indicate on it the TRS configuration as a hybrid and we hassled its proposition as a means of "social rehabilitation" that can work as a social homogeneity mechanism. On a second map, we cartographied mental captures through images and ways historically built from madness presented in the biopolitical contemporary game and we indicated that the resistance to such catches should be built on a politic daily basis as important vectors of the institutionalization process in mental health. Finally, on a third map we mapped the carefulness produced in the TRS, by analyzing the transition psychiatric hospital - TRS and the caregivers´ team work. On this mapping, the care, for the weakness in the coresponsibility field, is reveled crossed by mental, disciplinary and normality elements, but it is also built in resistance born from links in the intersubjective field of the caring work. We conclude, then, that the TRS power and the deinstitutionalization process itself were in building and strengthening affective labor micro political networks of life and liberty producers

Cartografia de uma intervenção comunitária para prevenção de DST/HIV/AIDS

Community-based interventions have been presented as a proposal of operationalization of the concept of vulnerability to STD/Aids prevention. This study aimed to analyze the Community intervention developed through the project Strengthening of Community action networks for STD/Aids prevention: know and intervenein, at Mãe Luiza neighborhood, in the city of Natal, State of Rio Grande do Norte, Brazil. The study was conducted in the same location where intervention occurs and took as time reference the first 30 months of construction and deployment process, from April 2010 until December 2012. This is research with qualitative approach, participatory character, developed from the immersion of the researcher in the field, being this community intervention itself. In this perspective, the study approximates to the Cartographic method in which the researcher-researched is engendered in the acts and effects research. The data-generating sources were the memories of the researcher from the field notes, written narratives of subjects involved in the intervention and documents pertaining to the project. In the methodological path of cartography, the image of the rhizome by Deleuze and Guattari (1995) has accompanied the immersion in the field given the nature of research-intervention which approach to the concept of object-Rhizome. The presentation of results was composed for the attempted rhizomatic and a hypertext representation, based on the descriptive narrative taken from the documentary analysis and the multi-faceted narratives with the voices, the looks and the affections narrated by the subject involved, respectively. On the path taken, three lanes were drawn as synthesis of learning produced by experience-that can contribute to understanding the process under study, in his singular character, and reflections on other experiences of community intervention: track 1- Community intervention as active-reflective space and a cause; track 2 Inclusion as power and challenge of community involvement; track 3 Sustainability as A challenge of Community intervention. The study indicates that community intervention is presented as a potential producer of health as also produces practical and creative skills, subjects and inventive in the daily life of the community with a view to reinventing knowledge and practices for the prevention of STD/HIV/Aids

Variabilidade espacial da produtividade do feijoeiro correlacionada com atributos químicos de um Latossolo Vermelho Distroférrico sob sistema de semeadura direta

O feijão, importante fonte proteica, é um alimento muito comum na dieta da população dos países latino-americanos, sendo o Brasil maior produtor mundial deste legume. Nacionalmente, seu cultivo no sistema de semeadura direta tem crescido ano após ano. em 2002, foi avaliada a variabilidade espacial do feijoeiro, em função dos atributos químicos de um Latossolo Vermelho Distroférrico no sistema de semeadura direta, em Selvíria (MS) no Cerrado Brasileiro. O objetivo do presente estudo foi selecionar, entre os atributos do solo pesquisado, aquele com a melhor correlação, linear e espacial, para explicar a variabilidade da produtividade do feijoeiro. Foi instalada uma rede amostral, para a coleta de dados do solo e das plantas, com 135 pontos amostrais, em uma área de 7500 m². A produtividade de grãos de feijão (PG) representou o atributo da planta, enquanto os do solo foram: P, MO, pH, K, Ca, Mg, H+Al, S, T e o V%. Estabeleceram-se correlações lineares, simples e múltiplas, entre a PG e os atributos do solo. Foram modelados semivariogramas para todos os atributos, obtendo-se as respectivas krigagens e validações cruzadas. Também foram estabelecidas as co-krigagens entre a PG e os atributos do solo. em relação à produtividade de grãos de feijão, 22% da sua variação foram atribuídos à variação nos atributos químicos do solo. Tanto linear quanto espacialmente, o pH do solo foi bom indicador da produtividade de grãos de feijão quando cultivado sob sistema de semeadura direta.

Custo de produção de amora-preta em região tropical

O cultivo da amora-preta é recente no Brasil. A espécie apresenta elevada adaptabilidade, baixa exigência em frio, facilidade de manejo, rusticidade e pouca utilização de defensivos agrícolas. É uma fruta que vem despertando elevada atenção dos consumidores devido à presença de compostos fenólicos com propriedades antioxidantes. Com este trabalho, objetivou-se analisar o custo de produção do cultivo da amora-preta, em primeiro ano de produção. Para estimar a matriz de coeficientes técnicos e os custos de produção, em 2007, os preços de venda foram levantados junto a um produtor, e o restante das informações foi obtido de um experimento. de acordo com os dados e os cálculos de custos, a primeira produção da cultura foi de 3.000 kg.ha-1, com custo de implantação e condução, no primeiro ano, de R$ 8.710,63, e no segundo ano, apresentou custo de R$ 6.467,50. o custo de produção foi relativamente baixo comparado com outras frutíferas perenes cultivadas na região, evidenciando que esta atividade pode ser mais uma alternativa de renda para agricultura familiar.

Evaluation of figs mutant selections cv. roxo-de-Valinhos

The fig (Ficus carica L.), belonging to the Moraceas family, is one of the most important fruit crops, bringing Brazil to the condition of the tenth largest fig producer and exporter in the world. But the culture presents some problems with plant protection, and in Brazil, it is all implanted with an only cultivar, Roxo-de-Valinhos, which produces seedless fruit, not permitting the conventional improvement. In this sense, the genetic improvement by using mutagenic becomes a very important research line, that can greatly contribute to the culture development. Considering this, this study aimed to evaluate selections of fig originated from mutant plants formed by cuttings from buds irradiated with gamma ray and compare them with the main varieties of the culture in commercial plantation. By using plants originated from 5 traditional fig cultivars cuttings and 5 fig mutant selections (formed by cuttings from Roxo-de-Valinhos buds irradiated with gamma ray, in the dose of 30 Gy), spaced by 2.5 x 1.5 m. The experimental layout was a completely randomized block design, with 10 treatments, 3 repetitions and 5 plants per plot. The evaluations are made from the plants vegetative growth as well as the fruit characteristics. Through data analysis, it seems that there is variability between the mutant selections and with the traditional cultivars, and the treatment PI-189 was superior to the standard cultivar Roxo-de-Valinhos on great commercial characteristics importance, such as "number of fruit per plant", "average weight per fruit" and "productivity", having the same traits, showing itself with enormous potential for future studies.

Consórcio de feijoeiro e milho-verde na entressafra. II- comportamento das cultivares de milho

The green corn demand, production of quality bean grain and better use of land and water resources can be used by small farmers through the intercropping of common bean and green corn in off-season crops. Field experiments were conducted in the Polo Regional Extremo Oeste-APTA, in Andradina -São Paulo State, in 2005 and 2006. The objective was to evaluate the performance of green corn cultivars grown in single crop and intercropped with common bean. The randomized blocks design with 8 treatments constituted by the combination of two corn (CATIVERDE 02 and XB 7012) and three common bean cultivars of different growth habits: IPR Colibri (I), IPR Juriti (II) and IAC Carioca (III), with four repetitions was used. The influence of the intercropping on the performance of corn was not significant. The hybrid XB 7012 was more productive in intercropping and in single crop. The hybrid production more 8000 commercials ears and lengt ears when compared with the variety. The intercropping with the IPR Juriti or IPR Colibri cultivars were the most profitable for the producer.

Screening and Production Study of Microbial Xylanase Producers from Brazilian Cerrado

Hemicelluloses are polysaccharides of low molecular weight containing 100 to 200 glycosidic residues. In plants, the xylans or the hemicelluloses are situated between the lignin and the collection of cellulose fibers underneath. The xylan is the most common hemicellulosic polysaccharide in cell walls of land plants, comprising a backbone of xylose residues linked by beta-1,4-glycosidic bonds. So, xylanolytic enzymes from microorganism have attracted a great deal of attention in the last decade, particularly because of their biotechnological characteristics in various industrial processes, related to food, feed, ethanol, pulp, and paper industries. A microbial screening of xylanase producer was carried out in Brazilian Cerrado area in Selviria city, Mato Grosso do Sul State, Brazil. About 50 bacterial strains and 15 fungal strains were isolated from soil sample at 35 A degrees C. Between these isolated microorganisms, a bacterium Lysinibacillus sp. and a fungus Neosartorya spinosa as good xylanase producers were identified. Based on identification processes, Lysinibacillus sp. is a new species and the xylanase production by this bacterial genus was not reported yet. Similarly, it has not reported about xylanase production from N. spinosa. The bacterial strain P5B1 identified as Lysinibacillus sp. was cultivated on submerged fermentation using as substrate xylan, wheat bran, corn straw, corncob, and sugar cane bagasse. Corn straw and wheat bran show a good xylanase activity after 72 h of fermentation. A fungus identified as N. spinosa (strain P2D16) was cultivated on solid-state fermentation using as substrate source wheat bran, wheat bran plus sawdust, corn straw, corncob, cassava bran, and sugar cane bagasse. Wheat bran and corncobs show the better xylanase production after 72 h of fermentation. Both crude xylanases were characterized and a bacterial xylanase shows optimum pH for enzyme activity at 6.0, whereas a fungal xylanase has optimum pH at 5.0-5.5. They were stable in the pH range 5.0-10.0 and 5.5-8.5 for bacterial and fungal xylanase, respectively. The optimum temperatures were 55C and 60 A degrees C for bacterial and fungal xylanase, respectively, and they were thermally stable up to 50 A degrees C.

Caracterização social e tecnológica da produção de uvas para mesa em pequenas propriedades rurais da região de Jales-SP

A viticultura é uma atividade relevante para os produtores rurais do Estado de São Paulo, sobretudo aqueles detentores de pequenas áreas. O presente trabalho teve como objetivo caracterizar os principais aspectos sociais e tecnológicos utilizados na produção de uvas para mesa na região de Jales (SP). Os dados foram levantados nos anos de 2009 e 2010, a partir da aplicação de questionários a 19 produtores de uva e do acompanhamento do ciclo de produção de 10 propriedades. Os produtores cultivam pelo menos três cultivares diferentes de uva, sendo as principais: 'Niagara Rosada', 'Itália' e 'Benitaka'. A área média das propriedades é de, aproximadamente, 21 ha, e a área média com parreiras de uva é de 2,4 ha. A maioria dos produtores não conta com assistência técnica regular, não segue recomendações de adubação e não emprega critérios técnicos para o manejo da irrigação. O controle de doenças é realizado de forma preventiva e intensa, chegando a superar 100 aplicações por ciclo, no caso das uvas finas para mesa. Os resultados devem subsidiar a realização de outras pesquisas, assim como programas de planejamento e transferência de tecnologia, proporcionando ao produtor um manejo mais adequado da cultura, bem como o desenvolvimento sustentável rural regional.
