A boa-fé objetiva na concessão dos incentivos fiscais / Humberto Antônio Barbosa Lima

This essay analyzes tax incentives concepts and existing discussions on national and foreing doctrine, especially in countries that influence our legal culture, such as Germany, United States of America, Spain, Italy and England, providing a detailed study about the requirements that must be observed to ensure that there be a legitimate concession of the same. All this using as argument the Constitutional Charter and the development of the Law, mainly through the principle of objective good faith, which acts as the limiting principle of administrative discretion in granting such tax incentives, as well as creative element of the new duties for the public managers in order to be more effective, efficient and transparent compliance with the pact between the government and society and the objectives pursued by the last. Always chasing a strong argument through a broad historical and philosophical analysis of the institutes discussed. Thus, through studies that reveal the necessary incidence of objective good faith in granting tax incentives to achieve the constitutional purposes, this work does not merely disclose what is wrong, but provides solutions to modify reality hitherto existing, ie, introduces ways to reduce the encumbrance of the odious and ineffective tax incentives in society and to redirect these values unjustly destinated for obscure interests to achieve the real reasons for the existence of tax incentives, especially economic development through the reduction of regional and social inaqualities and poverty eradication

A função social do contrato como concretização de direitos fundamentais nas relações privadas

This dissertation deals with the social function of the contract, based on constitutional principles, especially those relating to fundamental rights. The social function of the contract (general clause) is described in the Civil Code so intentionally generic, no precise criteria to define it. Because of the fluidity of this principle, it is justified its closer study, seeking to assess its various meanings and looking away from the legal uncertainty that an unlimited conceptual vagueness can cause. The social function of the contract arises from a transformation experienced in private law from the inflows received from the Constitutional Law, the result of an evolutionary process by which it became the state structure, leaving the foundations of the classical liberal state and moving toward a vision guided by existential human values that give the keynote of the Welfare State. Arose, then the concern about the effectiveness of fundamental rights in relations between individuals, which is studied from the inapplicability of fundamental rights in private relations (U.S. doctrine of State action), passing to the analysis of the Theory of indirect horizontal effect of fundamental rights (of German creation and majority acceptance), reaching the right horizontal efficacy Theory of fundamental rights, prevailing Brazilian doctrine and jurisprudence. It has also been investigated the foundations of the social contract, pointing out that, apart from the provisions of the constitutional legislation, that base the principle on screen, there have also been noticed foundations in the Federal Constitution, in devices like the art. 1, III, the dignity of the human person is the north of the relationship between contractors. Also art. 3rd, I CF/88 bases the vision of social covenants, equipping it for the implementation of social solidarity, as one of the fundamental objectives of the Republic. Still on art. 170 of the Constitution it is seen as a locus of reasoning in the social function of the contract, the maintenance of the economic order. It is also studied the internal and external aspects of the social function of the contract, being the first part the one that considers the requirement of respect for contractual loyalty, through the objective good faith, as a result of the dignity of the hirer may not be offended by the other through the contract. On the other hand, the external facet of the social function of the contract, in line with the constitutional mandate of solidarity, indicates the need for contractors to respect the rights of society, namely the diffuse, collective and individual third party. In this external appearance, it is also pointed the notion of external credit protection, addressing the duty of society to respect the contract. There has been shown some notions of the social contract in comparative law. Then, there has been investigated the content of principle study, through their interrelationships with other provisions of private and constitutional law, namely equality, objective good faith, private autonomy and dignity of the human person. We study the application of the social contract in contractual networks as well as the guidance of conservation of contracts, especially those denominated long-term captive contracts, considering the theory of substantive due performance, concluding with an analysis of the social contract in code of Consumer Protection

Natureza de mulher, nome de mãe, marca de negra: identidades em trânsito e políticas do corpo na comunidade quilombola de Boa Vista dos Negros

Las políticas de salud destinadas a las mulheres de la comunidad quilombola de Boa Vista son, de manera general, las mismas políticas destinadas al resto de las mujeres de la región rural del Seridó norterriograndense y también las que se corresponden con regiones marginales del Brasil entero. Aquí, el cuerpo femenino es concebido bajo parámetros universalizantes que lo toman como una entidad homogénea y comparable con otros cuerpos femeninos a partir de su traducción en índices, tasas y estadísticas. En este sentido, decimos que son cuerpos desnudos, cuya intervención no considera los rasgos exteriores, aquellos llamados de culturales, como marcadores de identidad. Por otro lado, la noción de Salud de la Mujer Negra propuesta por recientes políticas de Estado a nivel nacional, se muestra inexistente en la comunidad. El cuerpo que se se exalta hoy a partir de los parámetros de reivindicación étnica es un cuerpo negro, pero también bello, jovem e sobre todo, fuerte; donde la noción de salud no penetra. De esta forma, las dos políticas conciben sujetos sociales diferentes. Sin embargo, existe otro espacio, que es el espacio de las prácticas vernáculas, en el que las mujeres experimentan la articulación entre feminilidad y negritud, pero a partir de otros parámetros local e históricamente delineados. Aquí, tanto las trayectorias de las mujeres como las redes de parentesco y cuidado locales se muestran especialmente significativas, ayudando a comprender las concepciones particulares sobre el cuerpo que imaginan y practican las mujeres de esta comunidad, y revelando la importancia de la maternidad como principio ordenador de identidades sociales. Para eso, hemos realizado un trabajo de observación participante, una serie de 30 entrevista com mujeres de Boa Vista y un estudio de las redes de parentesco organizadas alrededor del término mãe. Con esto, demostramos que existe un espacio cargado de significados sobre el cuerpo femenino y la feminilidad que es construido a partir de una interpretación local de la triple condición de mulher, de mãe y de negra

Comportamento da adição do carbeto de nióbio (nBC) na matriz metálica do aço ferrítico 15kH2mfa

The 15Kh2MFA steel is a kind of Cr-Mo-V family steels and can be used in turbines for energy generation, pressure vessels, nuclear reactors or applications where the range of temperature that the material works is between 250 to 450°C. To improve the properties of these steels increasing the service temperature and the thermal stability is add a second particle phase. These particles can be oxides, carbides, nitrites or even solid solution of some chemical elements. On this way, this work aim to study the effect of addition of 3wt% of niobium carbide in the metallic matrix of 15Kh2MFA steel. Powder metallurgy was the route employed to produce this metallic matrix composite. Two different milling conditions were performed. Condition 1: milling of pure 15Kh2MFA steel and condition 2: milling of 15Kh2MFA steel with addition of niobium carbide. A high energy milling was carried out during 5 hours. Then, these two powders were sintered in a vacuum furnace (10-4torr) at 1150 and 1250°C during 60 minutes. After sintering the samples were normalized at 950°C per 3 minutes followed by air cooling to obtain a desired microstructure. Results show that the addition of niobium carbide helps to mill faster the particles during the milling when compared with that steel without carbide. At the sintering, the niobium carbide helps to sinter increasing the density of the samples reaching a maximum density of 7.86g/cm³, better than the melted steel as received that was 7,81g/cm³. In spite this good densification, after normalizing, the niobium carbide don t contributed to increase the microhardness. The best microhardness obtained to the steel with niobium carbide was 156HV and to pure 15Kh2MFA steel was 212HV. It happened due when the niobium carbide is added to the steel a pearlitic structure was formed, and the steel without niobium carbide submitted to the same conditions reached a bainitic structure

Estudo de Matérias-Primas do Rio Grande do Norte para Uso em Revestimento Poroso: Influência do teor de dolomita e temperatura de calcinação nas propriedades físico-mecânicas

The state of Rio Grande do Norte presents a great potentiality for the production of ceramic tiles because of having natural raw material in quantity and quality making its economical exploration possible, beyond the great energetic differential of the state, the natural gás. This works aims to study the influence of the dolomite and granulometry concentration and calcinations temperature in the obtaining of formulations for porous coverings which have to be coherent to the project,s specifications. The experiments have involved the physical-chemical and mineralogical characterizations of raw materials and mechanical tests in the dry and burnt proof bodies preceding a mixture experiment planning with the use of the response surface methodology, in order to get the best raw materials combinations to produce a ceramic mass with specific properties. The twelve ceramic masses studied in this work were prepared by the via dry process, characterized, shaped by uniaxial pressing and sinterized in the temperatures of 940ºC, 1000ºC, 1060ºC, 1120ºC and 1180ºC, using a fast burning cycle. The crystalline phases formed during the sintering in the temperatures in study have revealed the presence of anorthite and diopside beyond quartz with a remaining phase. These phases were the main responsible ones by the physical- mechanical properties of the sinterized proof bodies. The proof bodies after the sintering stage have presented water absorption higher than 10% and a good dimensional stability in all studied temperatures. However, the flexural breaking strength results in the temperatures of 940ºC, 1000ºC and 1060ºC, under the temperature zone of the vitrification of ceramic whiteware do not reach the flexural breaking strength specific for the porous wall tile (15 MPa), but in the temperature of 1120ºC next to the vitrification temperature zone, some whiteware ceramic (formulations) has reached the specified value for the porous wall tile. The results of this work have showed that the studied raw materials have great importance for used in the production of porous wall tiles (BIII)

A Dimensão objetiva dos direitos fundamentais: conceito e sistematização

This paper is about the objective dimension of fundamental rights, aiming to present a concept well-designed for this dimension, and establish a systematic teaching of the subject, presenting the developments of this dimension of fundamental rights. The objective dimension of fundamental rights arises related to the idea of linking the state of fundamental rights, transforming these rights as the foundation and purpose of the state. It is distinguished from that perspective of the subjective dimension of fundamental rights, which includes the fundamental rights in an individual-state relationship. Under the subjective prism, rights are seen as limits required by the individual, the state intervention in the lives of individuals. A new dimension goes beyond the perspective of the rights of the individual as a mere resistance in the face of the state, assigning those rights also an active mission, which generates a series of legal repercussions. These developments or "effectiveness" the objective dimension are studied. The first consists of Binding Effectiveness, and demonstrated a new respect for fundamental rights within the state structure, which creates concepts such as "linkage of state functions fundamental rights" and "state s duty to protect". There is also the Radiant Effectiveness in which are examined topics such as the "constitutionalization of Law" and the "application of fundamental rights to particular relationships". Studies are still Procedure Effectiveness, in the case of "objectification of the mechanisms of protection of fundamental rights" and "opening of the processes of state protection of fundamental rights to public participation"

Objetiva(ação) da medida e contagem do tempo em práticas socioculturais e educativas

This thesis describes and analyzes various processes established and practiced by both groups about the socio-cultural objective (action) the measurement and timing, mobilized some socio-historical practices as the use of the gnômon of the sundial and reading and interpretation of movements celestial constellations in cultural contexts such as indigenous communities and fishermen in the state of Pará, Brazil. The Purpose of the study was to describe and analyze the mobilization of such practices in the socio-historical development of matrices for teaching concepts and skills related to geometric angles, similar triangles, symmetry and proportionality in the training of mathematics teachers. The record of the entire history of investigation into the socio-historical practice, the formative action was based on epistemological assumptions of education ethnomathematics proposed by Vergani (2000, 2007) and Ubiratan D'Ambrosio (1986, 1993, 1996, 2001, 2004) and Alain Bishop conceptions about mathematics enculturation. At the end of the study I present my views on the practices of contributions called socio-cultural and historical for school mathematics, to give meaning to the concept formation and teaching of students, especially the implications of Education Ethnomatematics proposed by Vergani (2000) for training of future teachers of mathematics

Aplicação de indicadores webométricos nos programas de Pós-Graduação das engenharias recomendados pela CAPES

This study aims to identify, through the application of webometric indicators, which Post-Graduate Courses in Engineering recommended by the Coordination of Improvement of Higher Personnel Education (CAPES) in Brazil stand out in the web space, in relation to the communication process and dissemination of scientific information in the academic environment. For this, we analyzed the structures content of the sites, the use, through the conduct of investigations and searches, the quality of information available, as well as the structure of existent hypertexts in the sites of this universe of search. The tools and methodologies adopted for this study are: search engines (Google, Yahoo), Mapper software (Xenu Link Sleuth) and analysis software and visualization of networks (and Ucinet6 NetDraw). Webometric indicators are also used, such as size of the web sites, visibility, web impact factor, brightness and density of the network. These instruments provide a brief analysis and evaluation for this webometric study. Therefore, from the incursion of the literature used, it appears that there are many advantages of using this type of metric study in the so called Information Society. The obtained results could identify which postgraduate courses in engineering has a better availability of their information on the Web, as well to define which of these courses stands out in relation to the use of their information, which has been outstanding in respect to its impact factor and which offers a greater number of links that serve as a source of information for its users, contributing, in its turn, with the navigability of the same network. In summary, it is asserted that the webometric study presents promising results, which are able to achieve the proposed objectives, as well as identify the factors that contribute significantly to the good visualization of these sites in the network, thus helping the spread of information and scientific communication through the use of the Web.

Otimização dos parâmetros de monopolos planares de microfita para aplicações em sistemas de banda ultra larga

This work presents a theoretical and experimental investigation about the properties of microstrip antennas for ultra-wideband systems. Configurations of elliptic monopoles with different eccentricities and circular monopoles are considered. Two prototypes for each antenna configuration were built, one with the typical microstrip configuration and the other is similar to the first, except for a small aperture in the ground plane. Therefore, this work proposes to modify the configuration of the ground plane of the monopoles designed adding a rectangular stub, in order to optimize and improve the performance of such structures. The obtained results show that the introduction of that rectangular aperture in the ground plane allows an improvement of the frequency response for the considered antenna propotypes. It is observed a good agreement between the measured and simulated results. Finally, some proposals for future works are presented

Comparação entre planejamento estatístico experimental e análise dimensional em operações de mistura e separação para sistema óleo-água

This work aims to determine a better methodology to help predicting some operational parameters to a new design of mixer-settler on treating wastewater produced by petroleum industry, called MDIF (Misturador-Decantador à Inversão de Fases/ Mixer-Settler based on Phase Inversion MSPI). The data from this research were obtained from the wastewater treatment unit, called MSPI-TU, installed on a wastewater treatment plant (WTP) of PETROBRAS/UO-RNCE. The importance in determining the better methodology to predict the results of separation and extraction efficiency of the equipment, contributes significantly to determine the optimum operating variables for the control of the unit. The study was based on a comparison among the experimental efficiency (E) obtained by operating MSPI-TU, the efficiency obtained by experimental design equation (Eplan) from the software Statistica Experimental Design® (version 7.0), and the other obtained from a modeling equation based on a dimensional analysis (Ecalc). The results shows that the experimental design equation gives a good prediction of the unit efficiencies with better data reliability, regarding to the condition before a run operation. The average deviation between the proposed by statistic planning model equation and experimental data was 0.13%. On the other hand, the efficiency calculated by the equation which represents the dimensional analysis, may result on important relative deviations (up 70%). Thus, the experimental design is confirmed as a reliable tool, with regard the experimental data processing of the MSPI-TU

Uso urbano não potável de água de lagoas do sistema de drenagem de Natal

The detention and infiltration ponds of urban drainage system has function to protect the population from undesirable effects of floods. In general these ponds are not completly used and it potential is wasted. As it are disseminated at different places at cities it can reduce costs with water transport and permit water preservation of best quality. Some it utilities includes use in green areas irrigation, industrial among than cooling towers and boiler, soil compaction, cleaning urban road, pisciculture and fire fighting system. The quality these water is influenced by anauthorized sewage in the drainage system. This study was performed in six detention and infiltration ponds at drainage system of Natal, which aim was to verify the non-portable use these ponds on urban environment. As indirect aim would to incentive the water utilization these ponds as a water source to another uses in urban environment. These ponds represents the characteristics of detention and infiltration of Natal city and consequently of Brazil. As the water quality, the ponds presents following characteristics: three has apparently good quality, other showed intermediate condition and two had water polluted. Were performed twenty sample in each ponds and the following parameters assessed: pH, temperature, dissolved oxygen, turbidity, electrical conductivity, coliform thermotolerant, ammonia, organic nitrogen, TKN, nitrate, total phosphorus and alkalinity, bicarbonate, chloride, total hardness, calcium and magnesium hardness, total solids, TSS, TDS, COD and SAR°. To utilization on pisciculture we recommend use in ponds which presents the best quality. Only one pond presented higher pollutants and it not being appropriated for use in cooling tower. The content of solids suspension restricted the water use in all ponds in boilers. As water use in soil compaction, cleaning urban road and fire fighting system the water from these ponds are not appropriated. However, the recommended limits from literature are to domestic sewage, due to this, the parameters are restrictive to diminish the sanitary risk that could be offered with it utilization. The infiltration velocity of water these assessed ponds restrict a moderato use, however the effects are potentiated only in soil less sandy, which not occur in Natal. It is recommend the unrestricted irrigation utilization in ponds with best quality of water, and a restricted irrigation to ponds with worst quality of water. As load of pollutants, it is recommended a complementary treatment in those ponds whit higher load to diminish sanitary risks. In only one pond was found one helminth eggs and due to the convention formula of results, it was found for all ponds less than 1 helminth/liter eggs.
