Causes of death of thoroughbred racehorses at Octavio Dupont Veterinary Hospital, Brazilian Jockey Club, Rio de Janeiro

Existem poucas pesquisas que abordam estudos epidemiológicos de mortes em cavalos de corrida de uma forma ampla. A maioria restringe-se a uma afecção ou procedimento específico. O Brasil não possui um programa de monitoramento de mortes instituído. Através de um estudo descritivo em associação a metodologia multivariada de análise, realizou-se um estudo epidemiológico de causa mortis relacionadas com afecções musculosqueléticas (MS), gastrointestinais (GI), sistema respiratório (RES), neurológico (NEU) e mortes súbitas (SD) durante os anos de 2002 a 2008 no Hospital Octavio Dupont, Rio de Janeiro. Os machos representaram o sexo mais afetado e a causa mortis relacionada com a taxa geral de mortalidade por grandes grupos de causas determinadas apresentou a seguinte ordem decrescentemente: MS>GI>SD>NEU>RES. A maioria dos óbitos registrados foi de cavalos na faixa etária de quatro a cinco anos (ID4-ID5). Seguidamente, observaram-se as seguintes relações de correspondência: (Triênio = SM-ID>5-SD; ID>5-GI; ID4-5-MS; SF-ID<4-RES/NEU); (Quatriênio = SM - ID>5 - GI; SF - ID<4 - NEU; ID4-5 - MS; GI - ID>5). O presente estudo aponta a importância e necessidade de estudos epidemiológicos sobre lesões em cavalos atletas, objetivando o diagnostico, reconhecimento de fatores predisponentes e prevenção.

1930, a Paraíba e o inconsciente político da revolução: a narrativa como ato socialmente simbólico

This work is an attempt to show that the ideological conflict that has been developed by the hegemony of the 1930 Revolution historical events in Paraíba, conceptually turned into an insoluble social contradiction. It ocurred due to imaginary or formal resolutions of the literature that ended up by altering the epistemological rules of the relation between fiction and reality. The present work is based on The unconscious politics: a narrative as a socially symbolic act , book in which all the literary or cultural texts can and should be read as symbolic resolutions to insoluble social contradictions. From string to contemporary literature this phenomenon has been registered by the several ways of textual production turning the 1930 Revolution into one of the main elements which guides the political scene of Paraíba. The ideological groups still centered on the political resentment and committed to a political conflict forged the existence of two historical truths: one which suits the liberais , the winners, and another is of the 1930 conflict. This work argues in favour of the unconscious politics of the 1930 Revolution. This thesis considers necessarily the relation that the Paraibana society maintains with its past and how this past reaches in the present the liberation of a hidden and repressed truth through its narrativization. Beyond that, how the ideological partiality generated the political resentment through the way of thinking of the rivals under the perspective of the good and evil reveals its insoluble social contradiction. Process which comprehends varied narrative forms of the mass culture products and literary production, as in the methodological perspective pointed by Fredric Jameson that all literary or cultural texts can and shall be read as symbolic resolutions of true political and social contradictions. In the case of Paraiba we will have resolutions that search for the reasons which caused the death of João Pessoa: forgery and publicity of love letters, dispute over the official version of suicide commited by João Dantas, the man who assassinated João Pessoa

Avaliação do desempenho reprodutivo do Cavalo-Marinho Hippocampus reidi (GINSBURG 1933) do estuário do Rio Potengi (Rio Grande do Norte, Brasil) com vistas ao seu cultivo em bases sustentáveis

Os cavalos-marinhos têm cativado a imaginação e a curiosidade dos seres humanos por centenas de anos. No entanto, nos dias de hoje, esses animais correm um sério risco de extinção por fatores como a pesca desordenada para suprir os mercados de peixes ornamentais e da medicina tradicional chinesa e principalmente, a destruição do seu habitat. Nesse contexto, é crescente o número de estudos sobre a ecologia, a biologia (reprodutiva, especialmente) e o cultivo de várias espécies do gênero Hippocampus, inclusive para fins conservacionistas e de recomposição de estoques. Duas espécies de cavalos-marinhos são encontradas no Brasil: Hippocampus reidi Ginsburg 1933 e Hippocampus erectus Perry. No entanto, as informações sobre essas espécies estão basicamente restritas ao seu grau de ocorrência ou a sua área de ocupação. No presente estudo, foi avaliado o desempenho reprodutivo de Hippocampus reidi do estuário do rio Potengi (05° 47' 42'' S; 35° 12' 34'' W), em Natal, Rio Grande do Norte. Para tanto, cavalos-marinhos grávidos (n = 38) foram coletados no referido estuário nos meses de setembro, outubro e novembro de 2008 e julho, agosto, setembro e outubro de 2009 e mantidos em laboratório até que liberassem os filhotes. O comprimento padrão (CPA), altura (ATA), volume da bolsa (VB) e peso úmido (PuA) dos adultos, bem como o comprimento padrão (CPF), altura (ATF), peso úmido (PuF) e peso seco (PsF) dos filhotes foram determinados. Os resultados obtidos mostraram que houve correlações significativas entre o CPA e a ATA (r²=0,171), CPA e PuA (r²=0,624), CPA e VB (r²=0,256), ATA e PuA (r²=0,788), PuA e VB (r²=0,211), CPF e ATF (r²=0,903) e CPF e PsF (r²=0,163). A análise de correspondência (AC) que associou as classes do comprimento padrão dos adultos (CPA) e o volume da bolsa de H. reidi ao número de filhotes mostrou que animais entre 19 cm e 21 cm e com volume de bolsa entre 3 mL e 4 mL foram os que liberaram o maior número de filhotes. Os resultados do presente estudo também indicam que o tamanho mínimo de captura recomendado pela CITES (10 cm de altura) para H. reidi deve ser revisto, uma vez que não foram encontrados animais menores que 13,5 cm que estivessem grávidos. Finalmente, o número médio de filhotes por desova obtido no presente estudo (n = 775 ± 398 filhotes) realçou o potencial reprodutivo de H. reidi e a necessidade de estudos adicionais com esta espécie

A diversidade de lagartos na Caatinga é mediada pelos térmitas?

Intending to explain the extraordinary lizard coexistence levels found in Australian deserts, Morton & James (1988) figured out a hypothesis which defends that the termite diversity would bring about lizard radiation. This study aims to verify the validation of that hypothesis in Caatinga lizard assemblages. This study also objectives verifying if the termite defense mechanisms influence their consuming levels by lizards and if this pattern differs between different lizard lineages. Termites were collected using a standardized sampling protocol of termites. Besides using haphazard sampling, we collect lizards with 108 pitfall traps in each area. Intending to check the linkage between the termite and lizard assemblages, the lizard stomach contents were analyzed and then a canonical correspondence analysis was performed. The presence of nonrandom patterns of diet overlap among the lizard species was also examined. Aiming to check if the defense mechanisms of termite influence their consuming pattern by lizards it was performed a laboratory experiment where termite with different defense mechanisms were offered to lizards of two different lineages. We verified that lizard assemblages do not consume termites according to termite abundance in ecosystems. Furthermore, mean niche overlap lizard species did not differ significantly from that expected by chance. We found that termite chemical defense mechanism does influence the termite s pattern consuming by lizards. These results do not corroborate premises which support Morton & James hypothesis (1988) and point out that lizard do not chose termites based on their abundance, but, trying to avoid consuming termites which exhibit chemical defense mechanisms. This defense mechanism, however, may not be the only explanation to patterns of termite s consuming by lizards.

As aulas régias da Capitania da Bahia (1759 1827): pensamento, vida e trabalho de nobres professores

Simultanément à l' expulsion des jésuites du contrôles de l' éducaton formeI du royaume portugais, l'Ordre du 28 juin 1759 a décrété une reforme générale aux études, comme une des partie d'un ensemble de mesures modernisatoires qui ont été établisent dans le Royaume et dans ses domaines à la période comprise entre 1750 et 1777, pendant le royaume de D. José I et sous la direction de son principal ministre, Sebastião José Carvalho e MeIo, plus connu par le titre de noblesse de Marquis de Pombal. Notre thèse, locaIisée notament à la Capitanie de Bahia (Capitanie - division politique administrative du Brésil Colonie) entre les années de 1759 à 1827, a comme objet d'études les singularités du magistère bahianais et comme objectif, à partir de Ia référence théorique de l'histoire sociale des idées, comprendre comment les membres de cette nouvelle catégorie professionelle, crée pour préparés des cadres professionels mais bien qualifiés pour exercer leurs fonctions de burocratie de l'État, ont pris contact avec la pensée reforniste ilustré portugais du siècle XVIII, ont été véhiculé autant par des étrangérisés, comme par la législation pombalina (du Marquis de Pombal) et comme cet ensembIe théorique rapporté à la pensée, la vie et le travail d'enseignant de ces premiers représentants du magistère bahianais. L' analyse de la documentation (des lettres, et des ordres royals, des licences officielles pour exercer la fonction, et des serments des professeurs royal pour les plusieurs villages et capitanies; registres de correspondence reçues et envoyées par les chambres des villages; registres et correspondences expédiées par plusieurs autorités; provisions; tous les types de licences et autorisations; désignation; testament et inventaires) montre que les professeurs royals, malgré la quantité pas très nombreuses de membres, ont été extremement actifs sur les décisions les plus importantes de la période de celle qui est connue comme la crise du système colonial, qui, en Bahia, a eu ses particularités dans un mouvement d' émancipation politique seulement au mois de juillet 1823. Finallement, on a le but, dans le contenu de cette thèse de doctorat, d'offrir une connaissance sur l'histoire de l'éducation brésilienne et bahianaise qu' on retrouve encore entouré de doutes, préjugements et imterpretations équivoques qui insistent d'anaIyser le Brésil sous un stigmate du retard du royaume portugais, malgré sa production récente dans l'historiographie

As organizações não-governamentais e a educação básica oferecida aos pobres: do consenso da oferta à ação privatizante

This work articulates a discussion about the role of the Non-Governmental Organizations (NGOs) in the social policies scenario, privileging the basic education directed to the poor in Brazil, in the period from 1992 to 2002. It is a relevant theme, particularly due to the importance of the NGOs in both the national and international scope actions. The study assumes that the NGOs are instruments of control (social control) that filter the social demands towards the State, specially regarding the basic education directed to the poor. It also discusses the process of acknowledgement e expansion of the NGOs as a result of the political and economic conjuncture leading to the State reform, which had an impact on the field of social policies. A close examination of these complex relations was only possible through the understanding of the third sector establishment, having the NGOs as the main means. In this movement, relevant information of the reality are considered in order to delimit the extents of this phenomenon, with a brief reference to its origins, to the marks of its conjunctural relations, registering the multiple faces of these Organizations and the constutive elements of the debate among different visions regarding the third sector, having the NGOs as a part of its composition. With this approach, documents and publications by the NGOs and the government are researched. Based on this material, the purposes announced by these organizations are analyzed, considering the Brazilian social, political and economic conjuncture. The State of Maranhão has been chosen as an example of this context, due to the high levels of poverty and low school performance, and also given that a great many NGOs actions are more and more being held in that location in order to promote social policies. It has been concluded that the NGOs help strengthen the theses that show the decrease in the State responsibilities on free, public and quality education, and that such principle is being negotiated through the partners actions

Cultura organizacional e comprometimento dos funcionários do Soleil Suíte Hotel

This study examines the relationship of the types of organizational culture perceived in a business hotel with the nature of the link between individual and organization. This linkage between commitment and organizational culture has been little explored, both national and international, requiring more studies. Thus, the survey was conducted in Soleil Suite Hotel, located on the beach of Ponta Negra, city of Natal, Rio Grande do Norte. The independent variable of the proposed model was represented by the types of organizational culture, while the dependent variable was represented by the four dimensions of commitment. It was used in addition to the correspondence analysis, the arithmetic mean, the Pearson s correlation and the simple regression analysis. The results indicated the existence of relationship of the types of organizational culture with the kind of commitment shown by the officials, where the cultures of Group and Innovative, capable of generating an environment dedicated to the work as a team, the development and professional growth of the employees, as well as the creativity and individual freedom of each one to try new things, encourage the dominance of the dimensions Affective, Affiliative and Normative of the tie person-organization

Modelagem de dados de falhas de equipamentos de sub-superfície em poços de petróleo da Bacia Potiguar

This master´s thesis presents a reliability study conducted among onshore oil fields in the Potiguar Basin (RN/CE) of Petrobras company, Brazil. The main study objective was to build a regression model to predict the risk of failures that impede production wells to function properly using the information of explanatory variables related to wells such as the elevation method, the amount of water produced in the well (BSW), the ratio gas-oil (RGO), the depth of the production bomb, the operational unit of the oil field, among others. The study was based on a retrospective sample of 603 oil columns from all that were functioning between 2000 and 2006. Statistical hypothesis tests under a Weibull regression model fitted to the failure data allowed the selection of some significant predictors in the set considered to explain the first failure time in the wells

Adoção de tecnologias móveis em empresas do Rio Grande do Norte, Pernambuco e Ceará

One of the best examples of the Information and Communication Technology (ICT) evolutions is on the high capability of storing and processing data into smaller devices, creating a new business condition, the mobility . This mobility in a deeper analysis proposes a business remodeling in many different areas (business segmentations), through the Internet anywhere at any time, allowing managers and researchers to think again their actual models that work nowadays in companies and public institutions, modifying the way internal and external clients can be attended. This thesis analyzes issues on mobile business adoption, technological evolutions and the impacts caused by this new reality the access to information anywhere at any time . This research is exploratory and shows a compilation of similar papers and thesis describing how was conducted the survey within 50 companies in the states of Rio Grande do Norte, Pernambuco and Ceará. The statistics analysis showed the different level of mobile technology usage from simple voice communications to wide band data transmission. The analysis pointed that canonic correlation was the most effective type of analysis to describe the relations among all groups of variables showing which of them are relevant, or not, for mobile technology adoption

Busca heurística através de algoritmo genético e memético com construção de vocábulos para o problema de atribuição de localidades a anéis Sonet

Telecommunications play a key role in contemporary society. However, as new technologies are put into the market, it also grows the demanding for new products and services that depend on the offered infrastructure, making the problems of planning telecommunications networks, despite the advances in technology, increasingly larger and complex. However, many of these problems can be formulated as models of combinatorial optimization, and the use of heuristic algorithms can help solving these issues in the planning phase. In this project it was developed two pure metaheuristic implementations Genetic algorithm (GA) and Memetic Algorithm (MA) plus a third hybrid implementation Memetic Algorithm with Vocabulary Building (MA+VB) for a problem in telecommunications that is known in the literature as Problem SONET Ring Assignment Problem or SRAP. The SRAP arises during the planning stage of the physical network and it consists in the selection of connections between a number of locations (customers) in order to meet a series of restrictions on the lowest possible cost. This problem is NP-hard, so efficient exact algorithms (in polynomial complexity ) are not known and may, indeed, even exist

Heurísticas usando construção de vocabuilário aplicadas ao problema da atribuição de localidades a anéis em redes SONET/SDH

The SONET/SDH Ring Assignment Problem (PALAS) treats to group localities in form of some rings, being respected the traffic's limitations of the equipment. Each ring uses a DXC (Digital Cross Connect) to make the communication with the others, being the DXC the equipment most expensive of the net, minimizing the number total of rings, will minimize the total net cost, problem's objective . This topology in rings provides a bigger capacity of regeneration. The PALAS is a problem in Combinatorial Optimization of NP-hard Class. It can be solved through Heuristics and Metaheuristics. In this text, we use Taboo Search while we keep a set of elite solutions to be used in the formation of a part of the collection of vocabulary's parts that in turn will be used in the Vocabulary Building. The Vocabulary Building will be started case Taboo Search does not reach the best solution for the instance. Three approaches had been implemented: one that only uses vocabulary's parts deriving of Taboo Search, one that it only uses vocabulary's parts randomly generated and a last one that it uses half come of the elite and half randomly generated

Estratégias de aplicações sequenciais e paralelas da metaheurística otimização por enxame de partículas ao problema do caixeiro viajante

Particle Swarm Optimization is a metaheuristic that arose in order to simulate the behavior of a number of birds in flight, with its random movement locally, but globally determined. This technique has been widely used to address non-liner continuous problems and yet little explored in discrete problems. This paper presents the operation of this metaheuristic, and propose strategies for implementation of optimization discret problems as form of execution parallel as sequential. The computational experiments were performed to instances of the TSP, selected in the library TSPLIB contenct to 3038 nodes, showing the improvement of performance of parallel methods for their sequential versions, in executation time and results

Educação corporativa para Micro e Pequenas empresas: aplicação do MADEC em empresas do setor supermercadista

This study searches to supply an existing gap in the empirical research about the performance of controllers of Micron and Small Companies (MSCs) in the context of corporative education (EC) through the Method of Support of Decision in Corporative Education (MSDCE). In the context of MCSs, this is a pioneering work, for other works related to this thematic searched in literature are limited to conjecture the possibility of its implantation via cooperation between companies; moreover, they do not apply any type of diagnosis method or viability. The object of study is an association of supermarkets of the city of Natal/RN, composed by 16 stores, of what 14 had been searched. The main objective of this work was to apply the first stage of the MSDCE and to verify the possibility of implanting the Corporative Education in the searched MSCs. As a result, it was obtained the profile of the companies and the validation of the above-mentioned Method. The phase of diagnosis conceived through the implantation of the first stage occurred through visits to the stores, interviews, application of questionnaires and place observation. The first stage - strategical analysis for professional education - was divided in two phases: analysis of the current corporative situation and available identification of the involved difficulties and resources. The implantation of the first stage of the MSDCE in the Association of Supermarkets Parceiros da Economia demanded a mapping of abilities and demonstrated how the education management works, the main difficulties and limitations of the MCSs of the supermerket branch of Natal/RN. Beyond the technological aspects, it was verified that cultural and educational aspects need to be worked to reach efficiency in the process of implantation of a corporative education program

Algoritmo evolutivo paralelo para o problema de atribuição de localidades a anéis em redes sonet/sdh

The telecommunications play a fundamental role in the contemporary society, having as one of its main roles to give people the possibility to connect them and integrate them into society in which they operate and, therewith, accelerate development through knowledge. But as new technologies are introduced on the market, increases the demand for new products and services that depend on the infrastructure offered, making the problems of planning of telecommunication networks become increasingly large and complex. Many of these problems, however, can be formulated as combinatorial optimization models, and the use of heuristic algorithms can help solve these issues in the planning phase. This paper proposes the development of a Parallel Evolutionary Algorithm to be applied to telecommunications problem known in the literature as SONET Ring Assignment Problem SRAP. This problem is the class NP-hard and arises during the physical planning of a telecommunication network and consists of determining the connections between locations (customers), satisfying a series of constrains of the lowest possible cost. Experimental results illustrate the effectiveness of the Evolutionary Algorithm parallel, over other methods, to obtain solutions that are either optimal or very close to it

Melhoria da segurança pública: uma proposta para alocação de unidades policiais utilizando o modelo das p-medianas e do caixeiro viajante

The decrease in crime is one of the core issues that cause concern in society today. This study aims to propose improvements to public safety from the choice of points to the location of police units, ie the points which support the car and the police. For this, three models were developed in order to assist decision making regarding the best placement of these bases. The Model of Police Units Routing has the intention to analyze the current configuration of a given region and develop optimal routes for round preventative. The Model of Allocation and Routing for New Police Units (MARNUP) used the model of facility location called p-median weighted and traveling salesman problem (TSP) combined aiming an ideal setting for regions that do not yet have support points or to assess how far the distribution is present in relation to that found in solution. The Model Redefinition and Routing Unit Police (MRRUP) seek to change the current positioning taking into account the budgetary constraints of the decision maker. To verify the applicability of these models we used data from 602 points to instances of police command that is responsible for the capital city of Natal. The city currently has 31 police units for 36 of these 19 districts and police have some assistance. This reality can lead to higher costs and higher response times for answering emergency calls. The results of the models showed that in an ideal situation it is possible to define a distance of 500 km/round, whereas in this 900 km are covered by approximately round. However, a change from three-point lead reduced to 700 km / round which represents a decrease of 22% in the route. This reduction should help improve response time to emergency care, improving the level of service provided by the increase of solved cases, reducing police shifts and routing preventive patrols
