Os conflitos de competência normativa do estado regulador brasileiro no setor administrado pela ANP

The dissertation has by objective describe the administrative activity of regulation exercised by independent regulatory agencies, observing that this activity was already done before this structures creation, however, after a really deep administrative reform that had as objective built a Public Administration with more efficiency, it passed to be done with some own peculiarities of these new structures of regulation. The work gave especial attention to what concern the conflicts of normative competency that really often happen between ANP (Agência Nacional do Petróleo, Gás Natural e Biocombustíveis) and the legislatives organs of the Republic Federative of Brazil, because energetic area has unbelievable mater to any country, and the fact of some juridical norm be against the law and be accepted is very dangerous, it affronts the constitutional principle of the legality e may put in risk the democratic Estate of law, them, regulatory dogmatic must be scientifically knows, and developed, thought and especially there are so many doctrinaires divergences about regulation constitutionality. As a theorist point, the investigation got the Logical nocontradiction principle, according Hans Kelsen and Lourival Vilanova thought, doing a philosophical reflection about the system of positive law, in which there are many antinomies, or conflicts of norms, what include the conflicts of the administrative acts expedited by ANP and the legislation of the brazilian regulatory Estate. For a better understanding and exemplify some perplexities treated by the doctrinaire angle, this work did a lucubration about a possibility of a normative conflict between a ANP resolution and the municipal legislation in a specific case, also, brought several jurisprudences for the brazilians courts of justice, that confirm the empiric existence of normative conflicts among ANP s administrative norms and federal legislation. Finally, concludes observing that the regulation is not a legislative competency delegation to regulatory agencies, is just a new exercise of the administrative function, it is a technical specialization of the public administration, that using this know-how can acting with more efficiency, however the normative power of regulatory agencies must respect the empire of law, so in this terms, the dissertation suggests the ponderation of the constitutionals principles of efficiency and legality how form to harmonizing the democratic legitimate inherent to legal norm supremacy, with the perspective of an efficient economic and institutional development

Acordos internacionais sobre a produção compartilhada de recursos naturais: a unitização interestatal na área do petróleo e gás sob o enfoque constitucional brasileiro

The apportionment of natural resources between sovereign States is a subject that relates many aspects of International law, as long as Constitutional Law, at the execution and application phases of international treaties that regulates the exploration of common goods. In this sense, because of their natural characteristics that creates an environment of constant migration and fixation in transboundary regions, terrestrial or maritime, the petroleum and the natural gas bound a complex juridical apparatus that can control the sovereign rights involved. This research is aim at accomplishing a study concerning the international agreements that enable the non-unilateral action, specifically the unitization treaties between sovereign States, as a manner to resolve situations related to the individualization of oil and/or gas reservoirs that go across their national borders. These agreements will be analyzed considering the international public law sources theory, bearing in mind yet the already existed experiences in this sense, not disregarding the way that this fact could affect Brazil. It will begin with an historical incursion over the unitization institute, covering its main characteristics and its formation and execution procedures, and finally it will address the Brazilian legal system and the comparative law threats the institute. The clauses of these relevant agreements will be analyzed in details, concerning its particularities and its contents. Because these agreements are international obligatory rules of law, it is indispensable that they are considered under the auspices of the international law system, focusing their nature and the subjects of international law and establishing them as sources of the international law, analyzing them, then, as international rules and the applicable law to these juridical relations, the conventional established, the consolidated international custom and the applicable International Law principles, appearing the State s responsibility as an important subject for the verification of the acts lawful practiced by States. The analysis of the apportionment of these natural resources ends with the individualization of possible exploitable marine oil fields located between the exclusive economic zone and the continental platform ends and the region administrated by the International Seabed Authority. At last, the Brazilian constitutional system appears as the mechanism of integration, application and execution of the international unitization agreements in Brazil, detaching the format and the proceedings that the international treaties take to acquire validity at the national legal system, passing through the treaties interpretation and the applicable constitutional principles, coming to its application in Brazil, considering the existing constitutional peculiarities and the role played by the National Agency of Petroleum, Natural Gas and bio-fuel ANP

A onda do turismo na cidade do sol: a reconfiguração urbana de Natal

Space reading of Natal City and its reconfiguration from the intensification of tourist activity and the expansion of the services' sector, transiting, primarily, through the geography, the social sciences, the economy, in one main approach that is unaware of science's traditional limitations and recognizes the complexity that involves current world. In face of this agreement it analyzes the social-economic implications that remodel the spaces under the new economic view of services' sector, commanded by the tourism, in an intense process of city's reconfiguration, concentrating in three great axles and their irrigation ways. These changes were about the public-private relation (by the public politics) in the formation of new spaces and in the remodeling of the city's old areas, which, together, had contributed to the tourist activity's appropriation, returning it in a social-economic mosaic that owns obvious reflexes in its space. This fragmentation in the urbane cloth of Natal is expressed by social nature and economic points and, in the scenery, is manifested through the modern forms of city's space occupation by the local elites and services' sector, evidencing their status' district, as well as selecting those areas with bigger capacity to reply to the capital

Estudo do aproveitamento de resíduo de gesso como carga para compósito com matriz de resina expansiva de mamona

In the execution of civil engineering works, either by wasting during the coating of wall or demolition of gypsum walls, the generation of the gypsum waste involves serious environmental concerns. These concerns are increased by the high demand of this raw material in the sector and by the difficulties of proper disposal byproduct generated. In the search for alternatives to minimize this problem, many research works are being conducted, giving emphasis in using gypsum waste as fillers in composites materials in order to improve the acoustic, thermal and mechanical performances. Through empirical testing, it was observed that the crystallization water contained in the residue (CaSO4.2H2O) could act like primary agent in the expanding of the polyurethane foam. Considering that polyurethane produced from vegetable oils are biodegradable synthetic polymers and that are admittedly to represent an alternative to petrochemical synthetic polyurethane, this research consist an analysis of the thermal behavior of a composite whose matrix obtained from a resin derived from the expansive castor oil seed, with loads of 4%, 8%, 12% and 16% of gypsum waste replacing to the polyol prepolymer blend. Contributors to this analysis: a characterization of the raw material through analysis of spectroscopy by Fourier transform infrared (FTIR), chemical analysis by X-Ray Fluorescence (XRF) and mineralogical analysis by X Ray Diffraction (XRD), complemented by thermo gravimetric analysis (TGA). In order to evaluate the thermo physical properties and thermal behavior of the composites manufactured in die closed with expansion contained, were also carried tests to determine the percentage of open pore volume using a gas pycnometer, scanning electronic microscopy (SEM), in addition to testing of flammability and the resistance to contact with hot surfaces. Through the analysis of the results, it appears that it is possible to produce a new material, which few changes in their thermo physical properties and thermal performance, promotes significant changes and attractive to the environment

Avaliação da estabilidade térmica e oxidativa dos biodieseis de algodão, girassol, dendê e sebo bovino

The search for new sources of environmentally friendly energy is growing every day. Among these alternative energies, biodiesel is a biofuel that has had prominence in world production. In Brazil, law 11.097, determine that all diesel sold in the country must be made by mixing diesel/biodiesel. The latter called BX, , where X represents the percent volume of biodiesel in the diesel oil, as specified by the ANP. In order to guarantee the quality of biodiesel and its mixtures, the main properties which should be controlled are the thermal and oxidative stability. These properties depend mainly of the chemical composition on the raw materials used to prepare the biodiesel. This dissertation aims to study the overall thermal and oxidative stability of biodiesel derived from cotton seed oil, sunflower oil, palm oil and beef tallow, as well as analyze the properties of the blends made from mineral oil and biodiesel in proportion B10. The main physical-chemical properties of oils and animal fat, their respective B100 and blends were determined. The samples were characterized by infrared and gas chromatography (GC). The study of thermal and oxidative stability were performed by thermogravimetry (TG), pressure differential scanning calorimeter (PDSC) and Rancimat. The obtained biodiesel samples are within the specifications established by ANP Resolution number 7/2008. In addition, all the blends and mineral diesel analyzed presented in conformed withthe ANP Regularion specifications number 15/2006. The obtained results from TG curves data indicated that the cotton biodiesel is the more stable combustible. In the kinetic study, we obtained the following order of apparent activation energy for the samples: biodiesel from palm oil > sunflower biodiesel > tallow biodiesel > cotton biodiesel. In terms of the oxidative stability, the two methods studied showed that biodiesel from palm oil is more stable then the tallow. Within the B100 samples studied only the latter were tound to be within the standard required by ANP resolution N° 7. Testing was carried out according to the EN14112. This higher stability its chemical composition
