Le présent étude analyse les effets de la politique de financement de l éducation de base, par les Fonds contables, Fundef et Fundeb, et sa proposition de valorisation de l enseignement, en considerant les dimensions de la carrière et de la rémunération des professeurs de l éducation publique de l état du Rio Grande do Norte, entre les années de 1996 et 2000. Pour comprendre les contraintes de l évaluation des politiques publiques, en cherchant aussi les contribution en Marx (1996) selon qui « le concret est concret » et que la dialétique du concret peut appuyer pour la tentative de capter le fenomène étudié. On a utilisé encore le référentiel bibliographique relatif au financement de l éducation et la valorisation de l enseignement à partir de la littérature reférente aux dimensions de l objet (Fundef et Fundeb) et (carrière et rémuneration). Dans la recherche documental, au-delà des législations, directrices nationales et locales pertinentes, se sont utilisés des donnés référents aux ressources, disponibles à la Finbra, Trésor National, SIOPE/RN, INEP/MEC, des informations du résumé de la feuille et feuille de payement du Secrétariat d État, de l Éducation et de la Culture (SEEC) et 289 bulletins de salaire de 21 professeurs. On a réalisé interview semi structurée avec une quantité de 9 professeurs, reférent à la carrière, et un questionaire appliqué à 12 professeurs relatif à la remuneration. On considère que sur les résultats reférents aux indicateurs éducationnel, dans la période Fundef il y a eu une réduction des inscriptions aux écoles de l état comme aussi aux fonctions des professeurs de l Enseignement Fondamental, et cela correspond à 37%. À partir de la vigence du Fondebe (2007 - 2010) ces indicateurs ont équalisé. Pendant toute la période, 1996 et 2010 il y a eu une augmentation des inscriptions de 119,03%, et aussi aux fonctions des professeurs de 77,44%. Par rapport aux informations de financement, on a constaté que, du minimum exigé (60%) sur l aplication des fonds à la rémuneration de l enseignant, on applique pour la période des deux fonds, plus que le minimum exigé, c est-à-dire de 83,29% à 98,89% des fonds. Les effets des fonds sur la carrière des 9 professeurs n ont pas été satisfactoires, si l on considère la promotion et la progression. Au cas de la promotion des 9 de ces professeurs, un seul a évolué son niveau (les titres) mais a, au même temps, rétroagit dans sa progression. Pour la progression des 9 professeurs, 8 d entre eux ont sa progression retardée, ce qui correspond à entre 2 et 5 classes, et ce qui provoque un préjudice qui varie entre 10% à 45% sur sa remunération. La différence d une classe à l autre correspond à 5% de son salaire. On évalue que les avantages financières contribuent pour la remunération avec un pourcentage plus élevé que son salaire, ce qui diminuent pendant lo Fundeb. Par rapport à la remunération un professeur de 24 ans de service avec formation, n arrive même pas à gagner 2 salaires minimums. Le professeur de 30 ans de service, maître, reçoit un salaire, en 2010, qui correspond a moins de 3 salaires minimums, c est-à-dire, une proportion de 2,82 et une remuneration qui correspond à un peu plus que 3 salaires minimums, c est-à-dire, une proportion de 3,66. L enseignement n est pas très favorisé si on le met face à d autres profession qui ont aussi l exigence de formation supérieure, ce qui provoque un effet négatif pour voir l enseignement comme profession. À propos des effets sur la rémuneration, on conclue qu il y a eu une amélioration mais encore insufisante, surtout si l on compare au Salaire Minimum annuel. On évalue que les fonds Fundef et Fundeb n ont pas été capables de promouvoir la valorisation de l enseignement dans le contexte de carrière et rémuneration. On observe quelques résultats négatif dans la politique de fonds, une fois qu il y aurait en avoir avec l incapacité de tel politique en promouvoir la dite valorisation de l enseignement, ce qui est une des causes, le financement avec des restriction budgétaire

Este estudio analiza los efectos de la política de financiamiento de la educación básica, por intermedio de los Fundos contables, Fundef y Fundeb, y su proposición en valorar el magisterio, considerando las dimensiones de carrera y de la remuneración de los profesores de la red pública estadal de enseñanza del estado de Rio Grande do Norte, en el período entre 1996 y 2010. Para entender las condicionantes de la evaluación de las políticas públicas, se buscó también las contribuciones de Marx (1996) segundo quién “el concreto es concreto” y que la dialéctica del concreto se puede auxiliar en el intento de captar el fenómeno estudiado. Se utilizó aún, el referencial teórico bibliográfico relacionado al financiamiento de la educación y a la valoración del magisterio, a partir de la literatura referente a las dimensiones del objeto (fundef y Fundeb) y (carrera y remuneración). En la investigación documental, además de las legislaciones, directrices nacionales y locales pertinentes, se utilizaron datos referentes a los recursos disponibles en la Finbra. Tesoro Nacional, SIOPE/RN, INEP/MEC, datos de resumen del folio y folio de pagamiento de Secretaria de Estado, de la Educación e de la Cultura (SEEC), y 289 sueldos de 21 profesores. Se realizó entrevista semi estructurada con nueve profesores, referente a la carrera, además de un cuestionario aplicado a 12 profesores relacionado a remuneración. Se considera que en los resultados referentes a los indicadores educacionales, en el período Fundef ocurrió una reducción en las inscripciones de la red pública de enseñanza, como también en las funciones docentes, de la enseñanza base (fundamental), que corresponde a 37%. A partir de la vigencia del Fundeb (2007 – 2010), estos indicadores fueron puestos en ecuación. En todo el período entre 1996 a 2010, ocurre un aumento en las inscripciones de 119,03% y en las funciones docentes de 77,44%. Sobre los datos de financiamiento, se constató que, del mínimo exigido (60%) en la aplicación de recursos de los Fundos en la remuneración del magisterio se aplica en el período de los dos Fundos, pero el mínimo exigido, o sea, 83,29% a 98,89% de los recursos. Los efectos de los Fundos en la carrera de los nueve profesores, considerando la promoción y la progresión, no han sido satisfactorios. En la promoción de los nueve de estos docentes, apenas uno evolucionó el Nivel (titulación), pero retrocedió en la progresión. En la progresión de los nueve profesores, ocho se hallan con la progresión retrasada, entre dos y cinco clases, acumulando un perjuicio que varía de 10% a 45% en su ganancia. La diferencia de una clase a otra corresponde a 5% en la renta anual. Se observa que las ventajas pecuniarias contribuyen con la remuneración con porcentaje más alto que la renta, disminuyendo esta diferencia en el período de Fundeb. Sobre la remuneración, un profesor con 24 años de carrera, con formación (magisterio), no consigue, después de años de profesión, ganar ni siquiera dos salarios mínimos. El profesor con 30 años de carrera, con maestría, tiene una renta, en 2010, correspondiente a menos de tres salarios mínimos, o sea, 2,82 y una remuneración que equivale a poco más de tres salarios mínimos, o sea, 3,66. Si comparamos la profesión de magisterio con otras que igual exigen formación superior, la primera es, en general, de bajo nivel, causando un resultado negativo sobre la búsqueda de la profesión del magisterio. Por los efectos en la remuneración, se concluye que hubo una mejoría, pero aún insuficiente, sobre todo al comparar con el Salario Mínimo Anual. Se evalúa, una vez que los fundos – Fundef y Fundeb – no fueron capaces de promover la valoración del magisterio en las dimensiones de la carrera y de la remuneración. Se constatan algunos resultados negativos en la política de Fundo ya que tendría que ver, principalmente, con la incapacidad de la referida política a valoración de magisterio, siendo una de las causas, o financiamiento con restricción de presupuesto.

This Master s Thesis aims to use the theoretical models of growth with restricted balance of payments, specifically Kaldor (1970) and Thirlwall (1979) models, to analyze the behavior and the pattern of specialization of Brazilian exports and imports in the last years. It is observed that, in some periods, the pattern of specialization has contributed in restricting long-term growth of the Brazilian economy. It has been hypothesized that overall this is due to lack of structural transformation policies. To achieve this goal, it analyzed the performance of Brazilian exports and imports disaggregating them according to their technological content. The basis for comparison was a group of countries to which Brazil is inserted in, the BRIC. In this regard, the work is a comparative analysis by using descriptive statistics. It is concluded that the low rate of GDP growth experienced by Brazil since the 1980s can be explained in part by the decoupling of the Brazilian National Innovation System (NIS) and the Brazilian productive structure. This would be reducing the income elasticity of exports and raising imports, causing a pattern of specialization intensive primary commodities and labor and low-skill labor

This study aims to investigate the influence of the balance of payments constrained on economic growth in Brazil from 1991 to 2010. With this order, are shown some of the Keynesian balance of payments constrained growth models, inspired by Thirlwall (1979) and Kaldor (1970), which are supported by important points in common, such as adherence to the principle of effective demand. Given that within this theoretical perspective, there is no consensus about the best model to explain the growth rate allowed by the balance of payments constraint, the results are presented by the representative of the empirical literature that addresses the topic, which are necessary for understand the Brazilian case. From the estimation of the income elasticity of imports (0.85) via autoregressive vectors with error correction (VEC), it was calculated five growth rates of income, as predicted by the models of Thirlwall (1979), Thirlwall and Hussain (1982), Moreno-Brid (1998, 2003) and Lourenço et al. (2011) and compared with the actual growth rate. The empirical analysis has shown that: it can not reject the presence of external constraint in the Brazilian economy, there is a strong similarity in growth rates provided by different modeling suggest that growth with external constraint. In addition, when using data in quarterly for the period after 1990 there are no factors that could cause instability in the parameters of the import function (income elasticity and price elasticity of imports) within the period, which indicates that the structural break widely associated with the year 1994 was not confirmed by this study

Quadrotors aircraft are composed by four propellers mounted on four engines on a cross or x disposition, and, in this structure, the engines on the same arm spin in the same direction and the other arm in the opposite direction. By rotating each helix generates vertical upward thrust. The control is done by varying the rotational speed of each motor. Among the advantages of this type of vehicle can cite the mechanical simplicity of construction, the high degree of maneuverability and the ability to have vertical takeoffs and landings. The modeling and control of quadrirrotores have been a challenge due to problems such as nonlinearity and coupling between variables. Several strategies have been developed to control this type of vehicle, from the classical control to modern. There are air surveillance applications where a camera is fixed on the vehicle to point forward, where it is desired that the quadrotor moves at a fixed altitude toward the target also pointing forward, which imposes an artificial constraint motion, because it is not desired that it moves laterally, but only forwards or backwards and around its axes . This restriction is similar to the naturally existing on robots powered by wheels with differential drive, which also can not move laterally, due to the friction of the wheels. Therefore, a position control strategy similar to that used in this type of robot could be adapted for aerial robots like quadrotor. This dissertation presents and discusses some strategies for the control of position and orientation of quadrotors found in the literature and proposes a strategy based on dynamic control of mobile robots with differential drive, called the variable reference control. The validity of the proposed strategy is demonstrated through computer simulations

Timeplace learning is the capacity of organisms to associate both space and time with a biological relevant stimulus such as food. Experiments are usually done with food restricted animals due to the belief that food system activation is necessary for timeplace learning. Another line of thought suggest that, in addition to food system activation, response cost should be increased to effectively allow timeplace discrimination. The purpose of this experiment was to test whether a complex environment, which presumably implied in a heightened response cost, would facilitate timeplace association in satiated rats using a highly palatable food as reward. Nine rats were trained in a timeplace task for 30 nonconsecutive days. A large experimental box (1x1m) divided in four compartments was used. To access each compartment the animal had to overcome a series of obstacles such as ramps, staircases and mazes. Two feeders localized in opposite compartments were rewarded with sunflower seeds in two daily sessions. One feeder offered the reward during the morning sessions while the second feeder in afternoon sessions. After the 15th day of training, the animals began to show a preference for the correct feeder during the correct time of day expressed by increased frequency of visits as well as lower latency to access the feeders. These results suggest that satiated animals are also capable of learning a timespace task as far as the experimental context is complex enough to result in a higher response cost

The objective of this study was to evaluate the effects of the use of cashew bagasse bran (CBB) as food ingredient in qualitative feed restriction programs on the carcass traits, meat quality, organs weight and intestinal morphometry of barrows and gilts. Twenty – four crossbred pigs were used (12 barrows and 12 gilts) with an average initial body weight of 57.93 ± 3.67 kg/LW. The experimental designs was in randomized blocks 3x2 factorial arrangement with three level (0%, 15% e 30% CBB), two genders (barrows and gilts) and four repetition. A total of twenty-four instalments. The treatments were composed of basal diet (BD) formulated with corn, soybean meal and commercial base mix for finishing pigs, being containing different levels of CBB. At the end of the trial period the animals were slaughtered for the evaluation of the meat quality, traits carcass, Absolute Weight (AW) and Relative Weight (RW) of the organs and morphometric study of small intestine fragment. The inclusion of (CBB) in the diets did not affect the traits carcass of gilts, but interfered in the traits carcass of the barrow positively, increasing the yield of meat into cold carcass and reducing the thickness of subcutaneous fat, without affecting the fatty acid profile. However, we observed increased weight of organs and partial volume of absortiva mucosa of gilts. In the comparison between sex was observed a greater liver weight (AW) and (RW), and surface density of absortiva mucosa of barrow. The use of CBB was considered as ingredient to be used in programs of qualitative feed restriction for finishing pigs.

Este estudio tiene como objetivo evaluar los avances y límites de las políticas de accesibilidad en la ciudad de Natal. Se investigan las políticas publicas municipales de accesibilidad implantadas en los diez años subsecuentes, a partir de la sanción de la Ley Municipal de Accesibilidad Nº 4.090 del 03 de junio de 1992, que torna obligatorio la eliminación de las barreras arquitectónicas para personas con discapacidades en los lugares de circulación de peatones y edificios de uso público de la ciudad. Accesibilidad, en los proyectos de arquitectura y urbanismo es la condición esencial para asegurar a cualquier ciudadano su derecho a ir y venir con seguridad, dignidad y autonomía. Esta investigación se concentra en los barrios de: ciudad alta, Petrópolis y Ribeira, ya que esta área, en el período ya mencionado, fue la que tuvo una mayor concentración del presupuesto de inversiones públicas municipales de la ciudad de Natal, en la eliminación de barreras arquitectónicas en vías urbanas. El método adoptado fue el hipotético deductivo, a partir de la formulación de dos hipótesis de trabajo: la primera, una divergencia entre los objetivos propuestos por la Ley Nº 4.090 y sus aplicaciones prácticas y, la segunda, de las diferencias que existen en el grado de entendimiento del concepto de accesibilidad, para eso, se realizó una colecta y análisis de datos tanto empíricos como teóricos. Este estudio también retrata en el año de 2004, con el uso de la técnica de la fotografía, la realidad actual de la ciudad sirviendo como un parámetro comparativo con los proyectos asociados a la Coordinación para integración de las personas con discapacidades. Se utiliza la técnica de entrevista con especialistas en accesibilidad envueltos a lo largo del proceso de implantación de las políticas públicas en la ciudad de Natal, durante los años mencionados, obteniendo así un testimonio sobre las directrices adoptadas en ese período, con base en la legislación vigente. En la investigación documental y fotográfica se realiza una evaluación de la dimensión real de lo propuesto y ejecutado en un periodo de diez años, y se concluye sobre todos los avances y retrocesos de las políticas de gestiones públicas adoptadas con relación a la accesibilidad en la ciudad de Natal

This study aims at solidifying the theoretical bases to provide, above all, an explanation for this phenomenon which currently happens, with a scenario of social, political, economic and cultural transformations worldwide in medium cities. Nevertheless, because it has different dimensions from its transformation axes, gentrification comes with change, but also with the introduction of a new purpose in the space using and occupation, outlining in this context the identity of places from the formation of centralities with the presence of flows with social and economic dynamicsThe current forms of geographic space appropriation show the directions of the senses and ideological profile which recreates the meanings and uses of content and materials from descriptions of a historical past. However, today there is an economic context in the urban space which refers to a search of strategies for change, i.e., the acquisition of parameter aimed at meeting the demands of the relationship between capital and labor, which ends up overriding some actions for the specification of the transformation methods within the urban space to be explained by new needs and also by the agents from the value adding to their interests and investments. Thus, we assume that the appreciation/gentrification of urban spaces may or may not result from the building of a public space, since the dialogic structure as a place of political interaction externalize conflicts and disagreements in general; it keeps segregating spaces. As new spaces are transformed, the access to them tends to happen with particular restriction, whereas some places like parks, shopping malls, high-rise and horizontal condos are the scene for major professional and family events. In this context, the gentrification process is used to designate interventions in the urban environment, in certain city spaces which are considered central to public and private investments. A historical place is permitted to be presented as a scenario, a stage full of attractions, through the transformation process. Studying gentrification consists of an analysis of the underlying interests in the transformation of these areas, and especially of the assessment of the interest level in the private sector to partner in order to modify the landscape. Gentrification results from the transformation processes of capital, which influences the efforts and investments application in order to establish and achieve optimal economic growth, focusing on a location socio-culturally centered in the urban space. Thus, the urban social structure develops in the light of some questions that relate not only the cities growth but also environmental conditions it provides in cities like Mossoro, State of Rio Grande do Norte, Brazil 2005 a 2011.

Flowering is a fundamental process in the life cycle for plant. This process is marked by vegetative to reproductive apical meristem conversion, due to interactions between several factors, both internal and external to plant. Therefore, eight subtractive libraries were constructed using apical meristem induced or not induced for two contrasting species: Solanum lycopersicum cv. Micro-Tom and Solanum pimpinellifolium. Several cDNAs were identified and among these, were selected two cDNAs: one homologous cDNA to cyclophilin (LeCYP1) and the other to Auxin repressed protein (ARP). It has observed that LeCYP1 and ARP genes are important in the developmental process to plants. In silico analysis, were used several databases with the exclusion criterion E-value <1.0x10-15. As a result, conservation was observed for proteins analyzed by means of multiple alignments and the presence of functional domains. Then, overexpression cassettes were constructed for the ARP cDNA in sense and antisense orientations. For this step, it was used the CaMV35S promoter. The cDNA orientation (sense or antisense) in relation to the promoter was determined by restriction enzymes and sequencing. Then, this cassette was transferred to binary vector pZP211 and these cassettes were transferred into Agrobacterium tumefaciens LBA4404. S. lycopersicum cv. Micro-Tom (MT) and MT-Rg1 plants were transformed. In addition, seedlings were subjected to hormone treatments using a synthetic auxin (- naphthalene acetic acid) and cyclosporin A (cyclophilin inhibitor) treatments and it was found that the hormone treatment there were changes in development of lateral roots pattern, probably related to decreases in auxin signaling caused by reduction of LeCYP1 in MT-dgt plants while cyclosporin A treatments, there was a slight delay in flowering in cv. MT plants. Furthermore, assay with real-time PCR (RT-qPCR) were done for expression level analysis from LeCYP1 and ARP in order to functionally characterize these sequences in tomato plants.

Over recent years the structural ceramics industry in Brazil has found a very favorable market for growth. However, difficulties related to productivity and product quality are partially inhibiting this possible growth. An alternative for trying to solve these problems and, thus, provide the pottery industry the feasibility of full development, is the substitution of firewood used in the burning process by natural gas. In order to contribute to this process of technological innovation, this paper studies the effect of co-use of ceramic phyllite and kaolin waste on the properties of a clay matrix, verifying the possible benefits that these raw materials can give to the final product, as well as the possibility of such materials to reduce the heat load necessary to obtain products with equal or superior quality. The study was divided into two steps: characterization of materials and study of formulations. Two clays, a phyllite and a residue of kaolin were characterized by the following techniques: laser granulometry, plasticity index by Atterberg limits, X-ray fluorescence, X-ray diffraction, mineralogical composition by Rietveld, thermogravimetric and differential thermal analysis. To study the formulations, specifically for evaluation of technological properties of the parts, was performed an experimental model that combined planning involving a mixture of three components (standard mass x phyllite x kaolin waste) and a 23 factorial design with central point associated with thermal processing parameters. The experiment was performed with restricted strip-plot randomization. In total, 13 compositional points were investigated within the following constraints: phyllite ≤ 20% by weight, kaolin waste ≤ 40% by weight, and standard mass ≥ 60% by weight. The thermal parameters were used at the following levels: 750 and 950 °C to the firing temperature, 5 and 15 °C/min at the heating rate, 15 and 45min to the baseline. The results showed that the introduction of phyllite and/or kaolin waste in ceramic body produced a number of benefits in properties of the final product, such as: decreased absorption of water, apparent porosity and linear retraction at burn; besides the increase in apparent specific mass and mechanical properties of parts. The best results were obtained in the compositional points where the sum of the levels of kaolin waste and phyllite was maximal (40% by weight), as well as conditions which were used in firing temperatures of 950 °C. Regarding the prospect of savings in heat energy required to form the desired microstructure, the phyllite and the residue of kaolin, for having small particle sizes and constitutions mineralogical phases with the presence of fluxes, contributed to the optimization of the firing cycle.

Nowadays, in the plastic industry are used mills that accomplish the recycling of residues generated in the production of its components. These mills contain cut sheets that suffer accelerated wear, once they are submitted constantly to the tribologic efforts, decreasing its useful life. To reduce this problem, it s used noble steels or takes place superficial treatments. The ionic nitriding process presents some limitations related to the uniformity of the layer in pieces with complex geometry, committing its application in pieces as knives, head offices, engagements, etc. However, the new technique of nitriding in cathodic cage eliminates some problems, as the restrictions rings, inherent to the conventional ionic nitriding. In present work, was studied the use viabilization of steels less noble, as SAE 1020, SAE 4320 and SAE 4340, nitreded by two different techniques, to substitute the AISI 01 steels, usually used in the cut knifes fabrication, seeking to reduce the costs and at the sane time to increase the useful life of these knifes. The steel most viable was the SAE 4340, nitrided in cathodic cage, because it presented uniformity in thickness and in the hardness of the layer, besides of increased 58% in the average its useful life
