Aplicação do exame da proporcionalidade diante da implantação de empreendimentos eólicos em áreas de preservação permanente

The setting up of wind power enterprises at Permanent Preservation Areas reflects the obvious conflict and necessary convergence between free market and energy security on the one hand, and the promotion of environmental quality on the other. From the perspective of energy sustainability, and in order to achieve development (in its complex meaning, which converges economic, social, environmental and cultural aspects), the harmonization between free market and an ecologically sustainable environment is required. This work aims to identify the link between the protection system of the Permanent Preservation Areas and the current constitutional order, by analyzing the implementation of wind power enterprises in these protected zones focusing on the proportionality aspects. A legal and purposeful research was developed, from a theoretical method, followed by collecting and analyzing both primary and secondary data. From these data, the law, the legal literature and judicial decisions were cross-examined, under the light of the Constitution and guided by the theory of proportionality and related development imperatives. In this context, the present study identified the link between the principles of the economic order, environment and energy law, finding their basis under the Federal Constitution and development. By reproducing this interrelationship and by means of post-crisis institutional reforms, the guiding objectives of the Brazilian electric sector began to corroborate the precepts of development, although issues regarding its sustainability still persist. The appraisal of proportionality indicates that the Permanent Preservation Areas protection system is insufficient to materialize the right to a healthy quality of life upon the implementation of wind projects at Permanent Preservation Areas, albeit seeking the harmonization between free market and environmental protection.

Da casa grande ao condomínio fechado: o que mudou nas formas e modos de morar da família intergeracional no Nordeste e Sudeste do Brasil?

The focus of this study is to draw attention to the intergenerational family’s lifestyles and their various ways of cohabitation, in special to those families which are made by individuals of different generations, these families being constituted of, two or more individuals, or, two or more smaller families, which live under the same roof and have the elderly person as referential in their cohabitation. In those types of families, as for their ways of organization, it is interesting to note that the researches and productions done by inner architects and inner designers do not include this type of family arrangement because their studies do not cover this kind of structuralization nor was this type of organization put together with any of the ways of cohabitation. Therefore there is a theoretical concept void which is propositional, interventional and does not relate to the empirical reality. In observation to these remarks, the research starts a theoretic challenge of deconstruct or reconstruct our modern only habitational template, which is used today in all families configurations which out any regards to where this template will be used, unfitting to the intergenerational families who have elders. This study is then meant to give an differential analysis of the various domestic space’s templates in regards to the new families formats, their basic and special necessities, the home identities of those families which indicates the differential gap in housing and lifestyle from the higher social classes in comparison to the lower social classes. The interdisciplinary method was chosen in order to describe arrangements found in the lifestyles and the ways of cohabitation of the intergenerational families, this method is used for its knowledge base that better articulates the procedure method and the inductive reflexive approach made possible after an qualitative research. In order to accomplish that, an geographical space which tow real possibilities was selected, that is, the space where the people of great social and anthropological proximity are concentrated and the people which are the researcher kinships and friends, in between those are the habitants of Capim Macio’s, Candelária’s, Tirol’s and Petrópolis’s, neighborhoods, located in the south west zone of her home city Natal. It has been noticed that, meanwhile these intergenerational spaces do not claim their said spaces, because of their habits, necessities and relations in between generations and gender, their arrangements of said space are extremely creative. That means that alterations in the concepts of planning, construction and utilization of built spaces are imperative.

Estudo da influência de sistemas microemulsionados na molhabilidade de arenitos e na recuperação avançada de petróleo

Sandstone-type reservoir rocks are commonly responsible for oil accumulation. The wettability is an important parameter for the physical properties of the container, since it interferes in characteristics such as relative permeability to the aqueous phase, residual oil distribution in the reservoir, operating characteristics with waterflood and recovery of crude oil. This study applied different types of microemulsion systems - MES - in sandstone reservoirs and evaluated their influences on wettability and residual oil recovery. For this purpose, four microemulsion were prepared by changing the nature of ionic surfactants (ionic and nonionic). Microemulsions could then be characterized by surface tension analysis, density, particle diameter and viscosity in the temperature range 30° C to 70° C. The studied oil was described as light and the sandstone rock was derived from the Botucatu formation. The study of the influence of microemulsion systems on sandstone wettability was performed by contact angle measurements using as parameters the rock treatment time with the MES and the time after the brine surface contact by checking the angle variation behavior. In the study results, the rock was initially wettable to oil and had its wettability changed to mixed wettability after treatment with MES, obtaining preference for water. Regarding rock-MES contact time, it was observed that the rock wettability changed more when the contact time between the surface and the microemulsion systems was longer. It was also noted only a significant reduction for the first 5 minutes of interaction between the treated surface and brine. The synthesized anionic surfactant, commercial cationic, commercial anionic and commercial nonionic microemulsion systems presented the best results, respectively. With regard to enhanced oil recovery performance, all systems showed a significant percentage of recovered oil, with the anionic systems presenting the best results. A percentage of 80% recovery was reached, confirming the wettability study results, which pointed the influence of this property on the interaction of fluids and reservoir rock, and the ability of microemulsion systems to perform enhanced oil recovery in sandstone reservoirs.

Petrologia e geocronologia U-Pb do plúton granítico Serra da Rajada, porção central do domínio Rio Piranhas - Seridó, Província Borborema, NE do Brasil

The ediacaran plutonic activity related to the Brasilian/Pan-African orogeny is one of the most important geological features in the Borborema Province, represented along its extension by numerous batholiths, stocks, and dikes.The object of this study, the Serra Rajada Granitic Pluton (SRGP), located in the central portion of the Piranhas-Seridó River Domain is an example of this activity. This pluton has been the subject of cartographic, petrographic, geochronological and lithogeochemical studies and its rocks were characterized by two facies. First, the granitic facies were described as monzogranites consisting of K-feldspar, plagioclase (oligoclase - An23-24%), quartz and biotite (main mafic) and opaque minerals such as titanite, allanite, apatite, and zircon as accessories. Alteration minerals are chlorite, white mica and carbonate. Second, the dioritic facies consist of rocks formed by quartz diorite containing plagioclase (dominant mineral phase), quartz and K-feldspar. Biotite and amphibole are the dominant mafic minerals; and titanite, opaque minerals, allanite, zircon and apatite are the accessories. However, previous geological mapping work in the region also identified the presence of other lithostratigraphic units. These were described as gneisses and migmatites with undifferentiated amphibolite lenses related to the Caicó Complex (Paleoproterozoic) and metasedimentary rocks of the Seridó Group (Neoproterozoic) composed of paragneiss with calc-silicate lenses, muscovite quartzite and biotite schist (respectively, the Jucurutu formations, Equador and Seridó), the host rocks for the SRGP rocks. Leucomicrogranite and pegmatite dikes have also been identified, both related to the end of the Ediacaran magmatism and colluvial- eluvial and alluvial deposits related to Neogene and Quaternary, respectively. Lithogeochemical data on the SRGP granite facies, highlighted quite evolved rocks (SiO2 69% to 75%), rich in alkalis (Na2O+K2O ≥ 8.0%), depleted of MgO (≤ 0.45%), CaO (≤ 1.42%) and TiO2 (≤ 0.36%) and moderate levels of Fe2O3t (2.16 to 3.53%). They display transitional nature between metaluminous and peraluminous (predominance of the latter) with sub-alkaline/monzonitic (High K calcium-alkali) affinity. Harker diagrams show negative correlations for Fe2O3t, MgO, and CaO, indicating mafic and plagioclase fractionation. REE spectrum shows enrichment of LREE relative to heavy REE (LaN/YbN = 23.70 to 10.13), with negative anomaly in the Eu (Eu/Eu* = 0.70 to 0.23), suggesting fractionation or accumulation in the feldspars source (plagioclase). Data integration allows to correlate the SRGP rocks with those described as Calcium-Alkaline Suite of equigranular High K. The crystallization conditions of the SRGP rocks were determined from the integration of petrographic and lithogeochemical data. These data indicated intermediate to high conditions of ƒO2 (mineral paragenesis titanite + magnetite + quartz), parent magma saturated in H2O (early biotite crystallization), tardi-magmatic processes of fluids rich in ƒCO2, H2O and O2 causing part of the mineral assembly to change (plagioclase carbonation and saussuritization, biotite chloritization and opaques Sphenitization). Thermobarometrical conditions were estimated based on geochemical parameters (Zr and P2O5) and CIPW normative minerals, with results showing the liquidus minimum temperature of about800°C and the solidus temperature of approximately 700°C. The final/minimum crystallization pressure are suggested to be between 3 and 5 Kbar. The presence of zoned minerals (plagioclase and allanite) associated with lithogeochemical data in bi-log diagrams for Rb vs. Ba and Rb vs. Sr suggest the role of fractional crystallization as the dominant process in the magmatic evolution of SRGP. U-Pb Geochronological and Sm-Nd isotope studies indicated, respectively, the crystallization age of biotite monzogranite as 557 ± 13 Ma, with TDM model age of 2.36 Ga, and εNd value of -20.10 to the crystallization age, allowing to infer paleoproterozoic crustal source for the magma.

Evolução estratigráfica da sequência neocarbonífera-eotriássica da Bacia do Parnaíba, NE do Brasil

The Parnaíba Basin consists in an intracratonic basin whose sucession of rocks is arranged in five supersequences. The Upper Carboniferous-Lower Triassic Sequence represents the third major sedimentary cycle and corresponds to Balsas Group, which is divided into four units: Piauí Formation, Pedra de Fogo Formation, Motuca Formation and Sambaíba Formation, from base to top. Different interpretations have been made by several authors in recent decades to interpreted the depositional system and environments related to each unit that belongs to this sequence. In general way, it is described as a thick pack of siliciclastic sediments deposited under complex conditions, varying from clastic/evaporitic shallow marine to lacustrine and desert environment. Aiming to clarify the sedimentary sequence evolution, this work underwent a stratigraphic analysis of the Upper Carboniferous-Lower Triassic deposits by applying modern concepts of the sequence stratigraphy based on well and seismic database. Three main depositional sequences of higher frequency were identified in each well analyzed. The sequence 1 corresponds to rocks initially deposited by a fluvial system with braided channel characteristics which evolved to shallow marine with coastal sabkha conditions related to a transgressive stage, that later evolved to a deltaic system. The Sequence 2 corresponds to rocks deposited in a lacustrine/desert environment associated with sabkha generated during a period of increased aridity in which the area occupied by the Parnaíba Basin had been suffering. The registration of a major regressive phase is shown in Sequence 2 which evolved to a dominantly desert environment recorded in Sequence 3. Seismic stratigraphy analyses allow to define a series of stratigraphic surfaces and related genetic units, as well as to infer its lateral expression. Seismic facies associated with such sequences are dominantly parallel and sub-parallel, with good lateral continuity, suggesting the sedimentary rate was relatively constant during deposition.

Plano de desenvolvimento sustentável e articulação de políticas públicas: o controle de políticas ambientais pelo poder judiciário

The right to the preservation of a healthy environment is perceived as a Fundamental Right, inserted in the National Constitution and referring to present and future generations. The preservation of the environment is directly connected to the right to Health and Human Dignity and, therefore, must be treated as a personal right, unavailable, claiming for a positive response from the Brazilian State, through the development of related public policies, control of potentially harmful economic activities, with special focus on the principles of precaution and solidarity. The Brazilian judiciary must thus be attentive to the guardianship of the Fundamental Right. The judiciary control over the execution of public policies is based on obeying the principle of the separation, independence and harmony between the Powers, however it should never deviate from the constitutional obligation of caring for the effectivation of the rights and guarantees within the Magna Carta. In the balance between the principle of human dignity, from which springs the right to a healthy environment and the principle of separation of powers, the former should prevail, maintaining the latter to a core minimum.

O direito penal do inimigo na atualidade: Mutual Legal Assistance Treaty – MLAT, em matéria penal, celebrado entre a República Federativa do Brasil e os Estados Unidos da América bem como seus reflexos na jurisdição brasileira

In view of the climate of instability and deep social inequalities, it has been evident in the Brazilian reality, a new way to punish systematic already developed and consolidated in other countries, in which, among other things, the criminality is anticipated only by danger that the individual sports. It appears, therefore, that the theory developed by Günter Jakobs, nominated Criminal Law of the Enemy, became subtly inserted in the Brazilian reality as well as in international relations signed. In this sense, the Brazilian State, in order to carry out the international legal cooperation in the criminal field, signed a mutual assistance agreement with the government of the United States of America. Forward the conclusion of Mutual legal Assistance Treaty (MLAT), the signatory countries voiced a desire to cooperate in order to facilitate the implementation of tasks of the authorities responsible for law enforcement in both countries, comprising research, investigation, prosecution and prevention of crime, said internalized adjustment in the Brazilian legal system by means of Decree No. 3810 of 02 May 2001. Alongside these considerations, the present study aims to analyze the Criminal law of the Enemy today, seeking to find evidence of that theory in the MLAT, international legal cooperation instrument signed between the government of the Federative Republic of Brazil and the government of the United States of America. Moreover, it has the objective to describe its effects on the Brazilian jurisdiction, especially as concerns the relativity and the suppression of human rights. Once done the introit, analysis will be carried out in the first chapter, on the definition and main features of the theory of Criminal Enemy of the law, it is imperative to approach the humanistic aspect that preceded the theory as well as the dealings given to some controversial issues surrounding it, such as the anticipation of the enemy's punishment and the disproportionality of the penalties imposed. In the second chapter will present the conceptual assumptions, historical evolution and the positives aspects, as well as the barriers and the pursuit of effectiveness of international legal cooperation. In the chapter, bedroom effective analysis of specific modality of cooperation will be held, the Mutual legal Assistance Treaty - MLAT in criminal matters, signed between the Federative Republic of Brazil and the United States of America, in which the general aspects will be addressed and the MLAT reflections on the Brazilian jurisdiction, which includes analysis about the relativity or suppression of human rights, future trends and creating stricter laws, followed by the presentation of the seized conclusion on the subject, in which, among other approaches, will be voiced understanding about the unconstitutionality certain service requests that, from these, there is the bad use of the agreed instrument.

NA PALMA DA MÃO: A difusão de celulares e smartphones e possibilidades para o ensino-aprendizagem no Brasil

A pesquisa considera a difusão de celulares e smartphones e as consequências deste fato em possibilidades para o ensino-aprendizagem. Aparatos de comunicação sempre estiveram ligados ao processo de ensino-aprendizagem. Entretanto, com o desenvolvimento mais intenso, nas últimas décadas, das Tecnologias de Informação e Comunicação (TIC), essa relação vem ganhando novos contornos. Surge a Internet, a evolução das máquinas computacionais e, recentemente, a explosão dos dispositivos móveis, fornecendo novos produtos e serviços convergentes. Nesse contexto, celulares e smartphones tem sido utilizados e recomendados para apoio e complemento do processo de ensino-aprendizagem: a chamada Aprendizagem Móvel. Esse ramo cresce devido à rápida expansão e barateamento dessas tecnologias na sociedade. Para verificar cientificamente essa relação foi realizada uma pesquisa de natureza qualitativa, do tipo exploratória, com dois projetos de Aprendizagem Móvel em andamento no Brasil, o Palma – Programa de Alfabetização na Língua Materna e o Escola Com Celular – ECC. Assim, a partir dos dados provenientes da pesquisa, identificamos alguns aspectos relacionados ao uso de celulares e smartphones para o processo de ensino-aprendizagem que contribuem na compreensão desse campo ainda em construção no Brasil. O uso desses dispositivos como suporte para processos de ensino-aprendizagem nos projetos estudados é delineado pelos aspectos tecnologia, dispositivo, público e contexto e novas tecnologias e Aprendizagem Móvel. O aspecto dispositivo desdobra-se em dimensões como disseminação, multifuncionalidade e acessibilidade que embasam os projetos, ainda favorece características apontadas como importantes para o processo de ensino-aprendizagem na atualidade, como mobilidade e portabilidade. Os projetos pesquisados demonstram potencial e metodologia adequada aos contextos para os quais foram criados e aplicados. Entretanto, a pesquisa indicou que ao mesmo tempo em que celulares e smartphones representam o ápice da convergência tecnológica e são considerados extremamente populares e acessíveis na sociedade contemporânea, com possibilidades concretas como nos projetos estudados, não conseguiram conquistar uma posição sólida como suporte para o ensino-aprendizagem. Tal indicação se deve, de acordo com o corpus, à carência de alguns fatores, como: fomento, as práticas se mostram extremamente dependentes da iniciativa pública ou privada para sua extensão e continuidade; sensibilização para o uso de tecnologias disponíveis, não consideram o aparelho dos próprios alunos e um planejamento que inclua, capacite e incentive o uso desses dispositivos. Além disso, a pesquisa também destaca a necessidade de uma visão crítica do uso e papel da tecnologia nesses processos.

Liderança em Resorts: um estudo dos estilos praticados no Brasil

O segmento da Hotelaria é profundamente afetado pelo comportamento de seus líderes e suas características pessoais, e especialmente, pela maneira como influenciam seus seguidores a alcancarem este resultado. Sendo assim, o presente artigo tem como objetivo geral identificar e analisar os estilos de liderança praticados nos resorts do Brasil. Buscou ainda mapear no grupo de gestores, quais possuem o estilo de liderança transacional e transformacional pela opinião dos próprios gestores e de seus liderados. Para tanto, como método de pesquisa foi realizado um estudo exploratório descritivo de natureza quantitativa e qualitativa, junto a 169 funcionários de 14 resorts certificados pela Associação Brasileira de Resorts do Brasil de todas as regiões do país. Os dados coletados através da pesquisa quantitativa foram tratados por meio da técnica estatística de análise fatorial confirmatória, bem como de técnicas estatísticas de análise de frequência e variância. Já os dados obtidos através da pesquisa qualitativa foram analisados por meio da técnica de análise do discurso - Focus Group. Os resultados da pesquisa quantitativa demonstraram que o estilo de liderança predominante praticado nos resorts do Brasil é o Transformacional. Já os resultados da pesquisa qualitativa apresentaram-se de forma contrária e demonstraram que o estilo de liderança predominante é o Transacional. Esta discrepância entre os resultados das duas pesquisas levou à busca de um entendimento maior acerca das possíveis causas, chegando à conclusão de que a desejabilidade social pode explicar a diferença de opinião dos líderes e liderados participantes da pesquisa quantitativa.

Gestão do Conhecimento em Empresas Atuantes na Indústria de Software no Brasil : um Estudo das Práticas e Ferramentas Utilizadas

A gestão do conhecimento baseia-se em práticas e processos estruturados para melhor gerir conhecimento como um recurso. Associadas às práticas, também se verificam as ferramentas de tecnologia da informação e comunicação que viabilizam os processos de gestão do conhecimento. O presente estudo teve como objetivo verificar e apontar quais são as práticas de gestão do conhecimento e as ferramentas de tecnologia da informação e comunicação a ela associadas, mais utilizadas em empresas atuantes na indústria de software no Brasil. Para tanto, foi delineado um estudo descritivo de natureza quantitativa que teve como método de pesquisa o levantamento de informações junto a essas empresas. Assim, foram aplicados questionários a 319 funcionários de quinze empresas de software de grande e médio porte atuantes no Brasil. Outra forma de analisar os resultados encontrados considera uma visão baseada nas diferentes dimensões de práticas de gestão do conhecimento. Nesse contexto, a categoria de práticas de gestão do conhecimento que mais se evidenciou na pesquisa foi a dimensão estratégia. Há de se ressaltar que as práticas tratadas isoladamente obtiveram um comportamento diverso das práticas agrupadas em dimensões. Além da observação das ferramentas isoladamente, também foi possível apurar o desempenho das diferentes dimensões de ferramentas de tecnologia da informação e comunicação voltadas à gestão do conhecimento. Assim, a categoria de ferramentas que demonstrou maior influência foi a dimensão inteligência artificial. Também aqui deve-se atentar para o fato de que a observação individual das ferramentas acaba por oferecer um resultado diverso do apurado quanto aos indicadores agrupados em dimensões. Em função disso, há de se sublinhar que o desempenho de determinada ferramenta, de forma independente, pode não coincidir com o desempenho de sua respectiva dimensão.
