Política de turismo e desenvolvimento: uma avaliação do prodetur ii em Parnamirim/RN (2005-2012)

A dissertação avalia a efetividade do Programa de Desenvolvimento do Turismo na segunda fase (2005-2012) no município de Parnamirim/RN, busca-se verificar se este contribui para o desenvolvimento. Especificamente objetivou: a) Descrever as características e as ações do Programa de Desenvolvimento do Turismo no município de Parnamirim/RN; b) Identificar as percepções dos gestores públicos; da iniciativa privada e da sociedade civil a respeito da efetividade das ações do PRODETUR em Parnamirim e das repercussões do programa na qualidade de vida da população local; e c) Identificar as efetivações do PRODETUR na vida da população local que tenha participado de alguma ação do programa. Para tais pretensões, o percurso envolvendo a emergência e a consolidação do fenômeno turístico no seio da sociedade moderna, bem como o momento de intervenção do Estado no setor foi importante para verificar quais características estão imbuídas nas políticas públicas de turismo. Aliado a discussão do desenvolvimento para além do viés economicista, tendo as contribuições de Amartya Sen (desenvolvimento como liberdade) eixo norteador. Para a avaliação propriamente dita foram utilizadas as falas dos diversos atores locais envolvidos com o programa, compreendendo: gestão pública do turismo, iniciativa privada, sociedade civil e população local. Além de dados secundários coletados em instituições como IBGE e Secretaria Municipal/ Estadual de Turismo. Os resultados encontrados com a pesquisa nos mostraram que o PRODETUR II contribui com alguns elementos que podem cooperar para o desenvolvimento de Parnamirim/RN, pois este ocasiona efetivações significativas em cada bairro pesquisado. No entanto, é relevante observar que esses elementos estão aquém das reais possibilidades, uma vez que os resultados do programa poderiam ter sido mais substanciais. Neste sentido, ressaltamos que o fortalecimento da gestão pública e a mobilização da população local são elementos imprescindíveis para maior efetividade do PRODETUR nas próximas etapas

Política de assistência social no Brasil: uma análise a partir das tipologias de políticas públicas

The study of public policy typologies is still a knowledge field which lacks more embracing and applicable studies to different sectors. On that perspective, this work, Social Assistance Policy in Brazil: an analysis from the typologies on public policy, pursues to add the relevant literature to social assistance what focus on the public policy ratings. Moreover, it concerns about a study on the the national policy of social assistance implemented by the Brazilian government from the theoretical referrence of the public policy typologies. For that reason, the referential framework of the public policies as well as the analisys of its fundamentals/principles that are indispensable for achieving a bigger goal, that is to tipify the social assistance policy based on the different public policy typologies and characterize it through the main elements which are intrinsec to the social political and economic reality of Brazil. Thus, the issue suggested for the work is: what is the profile and the political trajectory of the social assistance implemented by the Brazilian Government? How it presents, above all, the features of a distributive, focused and lawful policy, the work has been done througho the following hypothesis: the social assistance policy in Brazil has been of universal, assistance, and focusing aspects. For each of those features granted to the social assistance policy, there is a gathering of changes according to the social, political and economic moment of the country and that stands out due to the different institutions within every cyclical period. The work showed that besides the social policy has gone through meaningful changes during the last decades, even though the adoption of the Organic Law of Social Assistance and its rules, some of the mentioned characteristics still remain, as long as the State s primacy goes on being the economic policies over the dubbed social policies. Notwithstanding, the social assistance will build up itself from the materialization of the growing of the social rights related to the State, but also assuming an important role on the amplified reproducing process regarding the capitalist social relations

Padre Miguelinho :o intelectual, o professor, o revolucionário - vozes que se fazem ouvir

This research work worries in building the history of the natalense priest Miguel Joaquim of Almeida Castro, Miguelinho, I don't just eat one of the heroes and martyrs of the Revolution From Pernambuco of 1817, as bill the traditional history, but also the educated man, the intellectual and the admired teacher. The studied period understands the beginning of the century XIX, when priest Miguelinho comes back to Brazil, coming of Portugal, to assume teacher's occupation in the Seminar of Olinda, and it ends in the year of 1817, marked by the Revolution From Pernambuco, one of the most important movements in the fight for the liberation of Brazil of the Portuguese domain. Miguelinho, one of the leaders of the Revolution, that also reached the provinces of Paraíba and of Rio Grande do Norte, it was executed by the real troops. Like this, he tries to understand the Priest's conflicting relationship, while representative clergyman, of a Church that almost obtained a religious monopoly, and your ideals per centuries more gone back to a social and economical order of Illumines, that even certain point condemned the attitude of the own Church. The objective, then, is to understand through the path of priest's Miguelinho life, not only the intellectual, the teacher and the revolutionary, but the representation of your political and pedagogic-educational ideas in a die historical moment and the creation of the republican myth, looking for the plurality of an universe that seeks, per times, to flee of our theoretical context

Sexing of murine and bovine embryos by developmental high-titer arrest induced by H-Y antisera

Murine and bovine embryos at the late morula stage were cultured in medium containing high-titer rat H-Y antisera. After 12 h of incubation, embryos blocked at the late morulae stage were classified as males and those at the blastocyst stage were classified as females. Sexing of murine embryos by PCR and cytogenetics revealed that 83% of the embryos classified as males and 82% of those classified as females had their sex correctly predicted (P < 0.05). Bovine embryos were transferred to recipient females. Pregnancy rates were 71.4% (10/14) for embryos classified as males and 68.8% (11/16) for embryos classified as females. The sex was correctly predicted for 80% (8/10) of the embryos classified as males and for 81.8% (9/11) of those classified as females (overall accuracy, 80.9%, P < 0.05). Therefore, the induction of developmental arrest by high-titer male-specific antisera was an efficient strategy for non-invasive embryo sexing. The procedure was straightforward and has considerable commercial potential for sexing bovine embryos. (c) 2004 Elsevier B.V. All rights reserved.

Método alternativo para submeter sementes de amendoim à solução de tetrazólio

A técnica para a determinação da viabilidade de sementes de amendoim por meio do tetrazólio (TZ) é, atualmente, aquela pela qual as sementes, após embebição em água, têm o tegumento removido. A seguir as sementes são, em grupo, imersas na solução de TZ. Essa técnica dificulta o contato entre os tecidos das faces internas dos cotilédones e a solução de TZ em virtude de que o período prévio de embebição em água não é suficiente para que os cotilédones das sementes de amendoim se separem. Assim, o acesso da solução de TZ aos tecidos das faces internas dos cotilédones e ao próprio eixo embrionário, que fica entre as duas faces cotiledonares internas, é consideravelmente dificultado. Na suposição de que este procedimento levaria a resultados de testes de TZ que se correlacionam mal com o desempenho germinativo das sementes no campo, tentou-se uma nova técnica pela qual as sementes, após a embebição em água, além de terem o tegumento removido, são manualmente separadas em seus cotilédones, com o eixo embrionário ligado a um deles, e os cotilédones de uma determinada semente, agora separados, imersos na solução de TZ contida em uma célula individual de uma bandeja de PVC. A hipótese aqui formulada mostrou-se correta : a técnica alternativa de submissão das sementes de amendoim à solução de tetrazólio permitiu a obtenção de resultados que, comparados com os da técnica convencional, refletiram de modo mais preciso o desempenho germinativo das sementes no campo.

Whole-genome expression profiling of Xylella fastidiosa in response to growth on glucose

Xylella fastidiosa is the etiologic agent of diseases in a wide range of economically important crops including citrus variegated chlorosis, a major threat to the Brazilian citrus industry. The genomes of several strains of this phytopathogen have been completely sequenced enabling large-scale functional studies. In this work we used whole-genome DNA microarrays to investigate the transcription profile of X. fastidiosa grown in defined media with different glucose concentrations. Our analysis revealed that while transcripts related to fastidian gum production were unaffected, colicin-V-like and fimbria precursors were induced in high glucose medium. Based on these results, we suggest a model for colicin-defense mechanism in X. fastidiosa.

Correlação entre leituras de clorofila e níveis de nitrogênio aplicados em feijoeiro

Foram realizados dois ensaios, sendo um em solução nutritiva e outro em solo, utilizando seis níveis de nitrogênio (28, 56, 84, 112, 140 e 168 mg/L de N) a fim de ajustar as leituras diretas, feitas nas folhas de feijoeiro, com um clorofilômetro (Minolta SPAD-501), aos níveis crescentes de nitrogênio e ao seu teor nas folhas. Avaliaram-se os parâmetros: área foliar; massas dos materiais verde e seco; teor de clorofila; produção de grãos e teores de N, Ca, Mg e S. Todos esses dados, mais as leituras do aparelho, foram correlacionados entre si e com os níveis de N aplicados. As correlações positivas entre as leituras e os níveis de N fornecidos (R = 0,86) e entre as leituras e os teores de N nas folhas (R = 0,75) indicam que há perspectivas favoráveis quanto ao uso desse equipamento para detectar deficiências de nitrogênio em feijoeiro.

Biossorção utilizando alga marinha (sargassum sp.) aplicada em meio orgânico

In this work, biosorption process was used to remove heavy metals from used automotive lubricating oils by a bus fleet from Natal-RN-Brazil. This oil was characterized to determine the physical-chemistry properties. It was also characterized the used oil with the aim of determining and quantifying the heavy metal concentration. Fe and Cu were the metals existent in large concentration and these metals were choused to be studied in solubilization process. For the biosorption process was used the seaweed Sargassum sp for the study of influencing of the metals presents separately and with other metals. It was also studied the effect of the protonation treatment of alga with the objective to know the best efficiency of heavy metals removal. The study of the solubilization showed that the presence of more than a metal favors the solubilization of the metals presents in the oil and consequently, it favors the biosorption process, what becomes interesting the perspective application in the heavy metals removal in lubricating oils used, because the presence of more than a heavy metal favors the solubility of all metals present. It was observed that the iron and copper metals, which are present in large concentration, the protonated biosorbtent was more effective. In this study we used as biomass the marine alga Sargassum sp to study the influence of agitation velocity, temperature and initial biomass concentration on the removal of iron and copper from used lubricant oils. We performed an experimental design and a kinetic study. The experiments were carried out with samples of used lubricant oil and predetermined amounts of algae, allowing sufficient time for the mixture to obtain equilibrium under controlled conditions. The results showed that, under the conditions studied, the larger the amount of biomass present, the lower the adsorption capacity of the iron and of the copper, likely due to a decrease in interface contact area. The experimental design led us to conclude that a function can be obtained that shows the degree of influence of each one of the system variables

Estudo da funcionalidade de espécies comestíveis do semiárido nordestino e estratégias para sua utilização como ingredientes para fins alimentícios

The Brazilian caatinga is characterized by low annual rainfall and arid soils. Several cactaceae, either native or adapted species, grow in this semi-arid region, including the prickly pear (Opuntia fícus indica) and facheiro ((Philosocereus pachycladus Ritter) which produce underexploited edible fruits. In addition to these species, the algaroba is a leguminous with little studied technological applications and bioactive potential so far. Therefore, this research aims to investigate the physicochemical, bioactive and functional attributes of the prickly pear and facheiro fruit pulps and the algaroba flour. Specifically, this study approaches the physicochemical characterization, total phenolic compounds (TPC) and the betalain identification and quantification by HPLC-DAD-ESI-MS. It is also investigated the DPPH antioxidant capacity and the antienzymatic activities against alpha-amylase and alphaglucosidase of water and ethanolic extracts of these food material. In order to address their potential to be used as food ingredients, juice blends prepared with mixtures of cajá and prickly pear, biofilms with facheiro and cereal bars with algaroba flour were elaborated and analyzed. The prickly pear fruits presented low acidity and high sugar content when compared to facheiro. The Philosocereus pachycladus Ritter fruits had higher protein and ash content, but the algaroba flour was the species with higher protein and sugar content among all. The algaroba flour also presented outstanding food fiber content, which reveals its potentiality to be used as a natural intestinal regulator. The TPC of water and ethanol extracts ranged from 3.87 to 16.21 mg GAE/100g for algaroba flour, 79.24 to 110.20 GAE/ 100g for prickly pear and 412.23 to 539.14 mg GAE/100g for facheiro. The 70% (w/v) ethanol extract reached the highest DPPH antioxidant activity, which was linearly correlated to its high TPC content. In regard to the enzymatic inhibitory activities, the best performance was observed for the prickly pear extracts which presented a moderate inhibition for both investigated enzymes, but interestingly, no alpha-glucosidase inhibition was observed for facheiro extracts. This work shows, for the first time in the literature, the functional attributes of facheiro fruits, as well as the presence of betacianins and isobetanin in the pulp of this exotic fruit. When it comes to the food products developed here, the sensory attributes that better described the juice blend cajá-prickly pear were sweetness, acidity, color yellow-orange, body, turbidity and cajá flavor. The discriminative test applied for cereal bars produced with and without algaroba revealed that the texture was the only sensory attribute that differed (p<0.05) between these two samples. It was also observed that the addition of facheiro extracts did not influence the visual characteristics of the biofilms. Overall, this work unveils the physicochemical and bioactive attributes of these commercial and technologically underexploited species widely found in the Brazilian caatinga and presents alternatives for their rational use
