Revitalização urbana de centros históricos: uma revisão de contextos e propostas: a Ribeira como estudo de caso

This dissertation focuses on the theme of urban revitalization in historical centers. It starts from a survey of international and national concepts and experiences about the subject, in special, the historical center of Ribeira, in Natal, Brazil. It gives more attention to local management and it is dedicated to the study of objectives and actions developed, basically, by two segments that manage works in the district. Companhia Docas do Rio Grande do Norte aims at the economical development of the state and it implies the enlargement of capacity of loading and unloading of the harbor of Natal and the Natal city counsil aims at urban preservation and revitalization. It was analysed speeches ans projects related to Ribeira and it was discovered that Natal has done very little to revitalize its historical center in the last two dacades. It analyses what seemed, or at least, should be a conflict of interests between incompatible projects, revealing both conciliatory proceedings and connivance between the participants in decision making. The conclusion directs attentions to the threat to historical building in the city and the importance of enhancing discussion about the future of our historical sites

Estratégia alimentar com ciclos de restrição e realimentação no desempenho produtivo de juvenis de tilápia do Nilo da linhagem GIFT

O objetivo deste estudo foi avaliar a ocorrência de resposta compensatória no desempenho produtivo de juvenis de tilápia do Nilo Oreochromis niloticus, linhagem GIFT, submetidos a diferentes estratégias alimentares. Foram utilizados 135 juvenis de tilápia, distribuídos em nove tanques de polietileno de 100L cada. As estratégias testadas foram: grupo controle (alimentado todo dia), grupo alimentado por cinco dias seguidos de dois dias de restrição de alimento (5A/2R) e grupo alimentado por quatro dias seguidos de três dias de restrição de alimento (4A/3R). Foram avaliados parâmetros físico-químicos da água e de desempenho produtivo. Os resultados foram submetidos à análise de variância, e as médias foram comparadas pelo teste Tukey, a 5% de probabilidade. A qualidade de água, o fator de condição e a conversão alimentar não foram influenciados pela estratégia alimentar. O grupo alimentado com a estratégia 5A/2R apresentou peso final, ganho de peso e taxa de crescimento específico semelhantes ao grupo continuamente alimentado (7,8 e 9,2g; 6,4 e 7,8g e 2,7 e 3,0% dia-1, para peso final, ganho de peso e taxa de crescimento especifico, respectivamente). A estratégia 4A/3R apresentou os piores resultados de desempenho produtivo, e a estratégia 5A/2R pode ser usada na alimentação de juvenis de tilápia do Nilo sem prejuízo ao desempenho produtivo, possibilitando inclusive redução de até 22,5% na quantidade de alimento ofertada.

Hiperidrose compensatória após simpatectomia toracoscópica: características, incidência e influência na satisfação do paciente

Hyperhidrosis is an idiopathic condition characterized by excessive sweating. Symptoms generally begin in childhood or early adolescence, and rarely improve with age. The excessive localized sweating generally occurs either spontaneously, or in association with stressful or emotionally charged situations. This prospective study aimed to investigate predictive factors for compensatory hyperhidrosis after thoracoscopic sympathicotomy. From 2000 to 2002, 80 patients (53 female and 27 male) underwent hyperhidrosis surgery. The patients, ranging from 12 to 56 years old, were studied and followed-up for 42.51 ±5.98 months. A satisfaction grading using a visual analogue scale -VAS (0 = not at all satisfied, and 10 = fully satisfied) was used. The surgical procedure was performed bilaterally on the second ganglion (T2) for facial hyperhidrosis, on the third and fourth ganglia (T3 and T4) for axillary hyperhidrosis, and on the third ganglion (T3) for palmar hyperhidrosis. The results showed that, 68 patients (85%) presented with compensatory sweating (CS), which was classified as mild (33.8%), moderate (33.8%) and severe (32.4%). Considering the final surgical results, 70 patients (87.5%) were satisfied with the outcome of the operation, while 10 patients (12.5%) were dissatisfied. Degrees of satisfaction varied according to sex, age, BMI and extent of denervation. Moreover, the compensatory hyperhidrosis was more severe in abdomen and back than in legs. In conclusion, although CS is a frequent adverse effect of sympathicotomy, the degree of patient satisfaction was high. Some factors were related to the occurrence and severity of CS and the most adequate patients to be submitted to this operation are young adult women whose BMI is less than 24.9

Effect of intermittent feeding on growth in early juveniles of the crayfish Cherax quadricarinatus

Three experiments were conducted with juveniles of the crayfish Cherax quadricarinatus to investigate the effect of intermittent feeding regimes on growth and the ability to tolerate the shortage of food. In experiment 1, stage III juveniles were assigned to one of seven intermittent feeding groups (from FS1: 1 day fed/1 day non-fed to FS7: 7 days fed/7 days non-fed) and two control groups, continuously fed (CF) and continuously starved (CS) animals; this experiment comprised a short-term intermittent feeding period until the first molt, followed by a continuous feeding period. In the experiment 2, stage III juveniles were assigned to one of three intermittent feeding groups (FS2 to FS4) and one control group (CF); it consisted of a prolonged intermittent feeding period, until the end of the experiment In the experiment 3, stage VI and VII juveniles were assigned to one of three intermittent feeding groups (FS2 to FS4) and one control (CF); it also consisted of a prolonged intermittent feeding period. The red claw crayfish juveniles were able to tolerate periods of intermittent feeding and underwent compensatory growth after continuous feed was re-established. The ability of crayfish to tolerate intermittent feeding was influenced by developmental stage and duration of the intermittent feeding period. Stage III juveniles survived, but decreased growth, when subjected to prolonged intermittent feeding. However, they showed full compensatory growth when the intermittent feeding period was short and followed by continuous feeding. on the other hand, stage VI-VII tolerated 60 days of prolonged intermittent feeding without any change in growth and survival. The hepatosomatic index (based on wet weight) values of the treatments and the control were similar, suggesting that intermittent feeding may not be considered a nutritional stress condition. The relative pleon weight (based on wet weight) values of the treatments and control were similar suggesting low use of nutrients from the muscle to increase the chance for survival. The juveniles of C quadricarinatus can tolerate relatively long periods of low food availability and this is an important adaptation for their survival in changing/unpredictable environments and an attribute favorable for the production of the species.

Physiological responses of the brown mussel Perna perna (Mollusca, Bivalvia) exposed to the anionic surfactant linear alkylbenzene sulphonate (LAS).

The effects of the Linear Alkylbenzene Sulphonate (LAS) were evaluated on the mussel Perna perna, using physiological and genotoxic biomarkers. The Micronuclei (MN) assay was used to estimate effects at nuclear level, whereas the physiological effects were evaluated by measuring the oxygen consumption and ammonia excretion rates. Significant effects were observed for the MN assay and the ammonia excretion rate, even in low concentrations. The oxygen consumption was not affected in the tested concentrations. For MN and ammonia excretion, the animals exposed to intermediate concentrations were not affected, but responded to the higher concentrations, indicating the existence of compensatory mechanisms at physiological level. However, parallel to this study other authors indicate the presence of progressive effects at the cellular level, suggesting that the organisms are not capable to recover of such increasing effects. Additionally, the results show that the levels of LAS observed for Brazilian coastal waters may chronically affect the biota.

Testemunhos de um tempo vivido : fragmentos e contextos de uma narrativa de Janduís-RN

Shows up the memory of the elderly, as a consistent experience in the in the construction of the social memory of Janduís, Rio Grande do Norte, where the research takes place. Through an autobiographic narrative, in a qualitative approaching, the intent is to stand up aspects about the individual history and collective memories, starting in a simple question: what did they remember? A question that turns into many others, as how the remember and under which circumstances. So, the lived and remembered moments are the subject of this paper, as these testimonials shows and reveals the citizens typical aspects, intending to telling (again) the city s history by the memories of this people. By oral statements and the analysis that followed, subjective aspects that made a social memory, highlight in violent episodes, that, now remembered, occurred in the historical sediment, which connects several social times, establishing a narrative standard. In Janduís, this standard is about the memory that sticks out their individual ways, and the collective life, in the past, standing out the fair and the events that occurred on it, as the most remembered place, where the memories go stronger. When they narrate are incorporated others facts, the story is reinvented, connecting the past to the future. The paper also revels builders subjects aspects of a social memory, as historical sediment that joins the social times. At the present moment, the fair, to them, is a place that doesn t exist anymore; for the city, is a place of enlargement of women s presence at the trending spaces, which means a place of social transformation. That being said, the fair, in both times, present and past, turns into a analysis object, with important elements to reference narrative s time and place. And how the narrative update the past recorded in the old citizen s memory. What was intended to do was articulate the memory and the history form temporal and special etching that define the place and the narrative context: the lived and the remembered at the group s day by day. In that way, were identify the collective memory s common elements, enunciating the memory and the narratives that update that history, influencing and being influenced, forming in memories in a collective phenomenon fueling the local imaginary

Mercado de trabalho, ocupações e rendimentos: a Região Metropolitana de Natal na década de 1990

The aim of this study is the labour market at Natal Metropolitan Region with emphasis in occupations and incomes that took place at the nineties. The definition of its chronological boundaries passed by verification of existence of evident socio-spatial impacts for output, occupation and income in national economy, with rebounds in all national territory, conditioned by institutional and socio-economical transformations which marked Brazilian insertion to capital flows and commodities globalization movement that took place at the cited decade. It has been shown that such impacts did not distributed themselves equally between diverse spatial levels (great regions, federate unities, municipalities) because of historical specificities in each place in terms of output structures and organization of distinct social agents. Having as its basis the Marxist perspective, it tackled theoretically occupations and incomes, transformations in labour universe occurred at world level, mainly in most urbanized areas, and following that to focus changes occurred in Brazilian society related to the search for competitive insertion in global economy during the period regarded. Special attention was gave to Natal Metropolitan Region, because it was historically a concentration area for investments, productive structure, people, occupations and incomes generated/appropriated in Rio Grande do Norte State. The basic data sources for research were the demographic Census (micro data) made by the Instituto Brasileiro de Geografia e Estatística (IBGE) intending to present the structure and the labour market dynamics, having as basis: 1) traditional indicators about labour market; 2) sectors of economic activities and 3) social positions and classes segments. One of the purposes is the demonstration that occupations and incomes keep relation with the restructuring which occurred in each specific sector during the period. Other purpose is to make explicit the factors which bear the participation of distinct segments in production or service execution that make possible the different participation in income distribution. Results are revealing the increasin precariousness in labour market, enlargement of occupations in tertiary sector and greater concentration of average incomes in the social segments which were owners of the greatest capital allowances between residents in Natal Metropolitan Region during the nineties

Empreendedorismo ambiental e preservacionismo compensatório: o turismo e as unidades de conservação Parque Estadual das Dunas e Área de Proteção Ambiental Jenipabu-RN

This doctoral thesis addresses the environmental issues and its vinculum with the tourism through the protected natural areas, in particular the conservation units, which consists in territorial areas created and demarcated by the government in order to protect ecosystems that have a high ecological and scenic-landscaped representativeness designed to the contemplation and controlled public visitation. In regard to its use for the touristic activities, are conceived while socio-environmental and symbolic materiality built around an imagery view of a nature-show, designed to attract visitors, aiming ensure the maintenance and reproduction of the capital in an entrepreneurial and preservationist way in the Metropolitan Region of Natal. It s a study about the Dunes State Park Jornalista José Maria Alves and the Jenipabu Environmental Protected Area, both created with the purpose of favor the implantation and empowerment of the touristic area through the State intervention as the main articulator agent of a new process of urbanization that uses the city marketing and the ideological discuss of environmental sustainability to recreate the imaginary of lost paradise and incorporate into the daily universe of tourists visiting the state of Rio Grande do Norte. The unveiling of this empirical reality made possible the construction and defense of the terms environmental entrepreneurship and compensatory preservationism, to explain how the formatting and idealization of this paradisiacal scenarios produce the commoditization of nature in an efficient and competitive way

ACRE: uma experiência inovadora de Governança?

About two decades ago Brazil has been suffered some important political changes on its government and supporter systems. In these changes the Partido dos Trabalhadores (Workers support) has been researched significant results as much legislation as executive ways. These conquests propitiate a structure for it to get an alternative motion in order to manage public goods by petista government way. Trying to examinate this we can study the Partido dos Trabalhadores government experience in Acre (1999-2002) to know about why the PT government characteristics are different from the others. To do this we assumed to conjecture a popular participation with priorities inversion and ethics in public resources administration. These are the elements of PT government way. This way we started our work making an evaluation of its bibliography. Them we do a field inquiry to analyses documents of the government projects (budget rules law, papers, approved laws, IBGE, PNUD, TSE) and semi-structured interviews with some characters of recent political Acres life. The scheme and the analysis about these givens disclose that weren t confirmed our hypothesis in part, since PT remained old local politics habitus. In other side the executive administration on PT government has got to inflect the Governance . Further on an efficient management as World Bank dispossess but PT absolve many requests of progressive sectors as well it expanded the society participation to resolutions process. By a cabinets enlargement. So it rescues a total administrative course which is printed in the called petista government way. Personally we think so it means important advancements in this Acre government way

A gestão participativa em administrações municipais:as experiências de Natal e Maceió

Our object is to analyze the experiences in participative management in the cities o Natal and Maceió. The center of our interests is to evaluate if the operational changes in public administration in Brazil have really caused transformations in the municipal government which tend to constitute democracy in our country. The enlargement of civil society participation experiences in public management (at least as a proposal) has led to a great diversity of results even when executed by individuals from the same political party or with the same ideological interests. Thus, we investigate why the participative management process takes place in different forms even when the managers belong to the same party and share the same ideas. We based our analysis in the analytical scheme developed by Esping-Andersen (1991) in his studies about the cause for different welfare states in the world. We defend the thesis that the specifities in management are explained through an integrative analysis between the capacity of organization existent in society, the kind of govern coalition and the institutional legacy present in both cities. The complete analysis of the two experiences studied shows that there are similarities specially in the mayors government forms and in the importance they give in their speech to the participation of society as the element which sustains the management. Nevertheless, although both mayors are connected to the political party project, there are also differences in the advance of such process mainly because of the basis work performed by the left party among the popular movement, the kind of govern coalition which has been developed in the city and by the institutional legacy left by the former administration

Tricuspid valve dysplasia and Ebstein's anomaly in dogs: case report

Dois casos de displasia da valva tricúspide são relatados neste trabalho. Os cães foram avaliados devido à fraqueza e presença de ascite. em ambos os casos, o exame ecocardiográfico mostrou insuficiência tricúspide e, em um deles, a inserção dos folhetos da valva tricúspide encontrava-se deslocada para baixo do ventrículo direito, caracterizando a anomalia de Ebstein. A terapia medicamentosa para insuficiência cardíaca congestiva foi iniciada, mas um dos animais veio a óbito subitamente alguns dias após o diagnóstico. O outro cão, apesar de inicialmente ter apresentado melhora significativa do quadro clínico, apresentou morte súbita. A necropsia dos animais revelou dilatação atrioventricular direita e folhetos tricúspides espessados. As características clínicas, métodos de diagnóstico e terapia medicamentosa são discutidas neste artigo.
