Os instrumentos de incentivo à produção e uso de biodiesel no Brasil: uma análise constitucional sob o princípio do desenvolvimento sustentável

The recent insertion of biodiesel derived from oily vegetables in the Brazilian energetic matrix calls for the study of some aspects that belong to it. The analysis of the carbonized energetic pattern concerns the paradigm of economic development that is constitutionally enshrined sustainable development which make environmental protection compatible with the needs of the economic rationality. This text is structured according to the ideas of modern hermeneutic that sees substantial value in the principles capable of create a harmonious relationship between law and society. The study of the constitutional principles to conduct a legal analysis about the National Program for Production and Use of Biodiesel - PNPB. The aim of the research is the study of PNPB ahead with the constitutional principles governing the economic order. To achieve this end we studied the sustainable development as a constitutional principle. We start with the notion that the thematic principles, and fundamental to understanding the dimension of sustainable development institute, since its concept is closely related to the applications of the principles enshrined in virtually all the constitutional order of the Western world. Then this was the National Energy Policy, initiating the approach by guiding principles of the National Energy Policy to develop the theme of public policy in the energy sector. Therefore, we studied the National Program of Biodiesel Production and Use - PNPB. From a technical introduction to the concept of biodiesel and a brief historical background, analyzing their advantages compared to fossil fuels predominantly used. Then it became a regulatory overview of the Brazilian legislation on the subject, central to understanding the plans and objectives pursued by the Brazilian government with encouraging the production of biodiesel. Finally discussed the tax incentives for production and use of biodiesel in Brazil. From the idea of federalism, characterized the tax as an instrument of state intervention in the economy. And finally it brought the tax incentives of Law No. 11.116/2005 in the face of the constitutional principles of economy and tax, and tax incentives from projects related to the Kyoto Protocol

O direito à saúde e a política nacional de atenção oncológica: uma análise a partir da crescente judicialização dos medicamentos antineoplásicos

The 1988 Federal Constitution of Brazil by presenting the catalog of fundamental rights and guarantees (Title II) provides expressly that such rights reach the social, economic and cultural rights (art. 6 of CF/88) as a means not only to ratify the civil and political rights, but also to make them effective and practical in the life of the Brazilian people, particularly in the prediction of immediate application of those rights and guarantees. In this sense, health goes through condition of universal right and duty of the State, which should be guaranteed by social and economic policies aimed at reducing the risk of disease and other hazards, in addition to ensuring universal and equal access to actions and services for its promotion, protection and recovery (Article 196 by CF/88). Achieving the purposes aimed by the constituent to the area of health is the great challenge that requires the Health System and its managers. To this end, several policies have been structured in an attempt to establish actions and services for the promotion, protection and rehabilitation of diseases and disorders to health. In the mid-90s, in order to meet the guidelines and principles established by the SUS, it was established the Política Nacional de Atenção Oncológica PNAO, in an attempt to sketch out a public policy that sought to achieve maximum efficiency and to be able to give answers integral to effective care for patients with cancer, with emphasis on prevention, early detection, diagnosis, treatment, rehabilitation and palliative care. However, many lawsuits have been proposed with applications for anticancer drugs. These actions have become very complex, both in the procedural aspects and in all material ones, especially due to the highcost drugs more requested these demands, as well as need to be buoyed by the scientific evidence of these drugs in relation to proposed treatments. The jurisprudence in this area, although the orientations as outlined by the Parliament of Supreme Court is still in the process of construction, this study is thus placed in the perspective of contributing to the effective and efficient adjudication in these actions, with focus on achieving the fundamental social rights. Given this scenario and using research explanatory literature and documents were examined 108 lawsuits pending in the Federal Court in Rio Grande do Norte, trying to identify the organs of the Judiciary behave in the face of lawsuits that seeking oncology drugs (or antineoplastic), seeking to reconcile the principles and constitutional laws and infra constitutional involving the theme in an attempt to contribute to a rationalization of this judicial practice. Finally, considering the Rational Use of health demands and the idea of belonging to the Brazilian people SUS, it is concluded that the judicial power requires ballast parameters of their decisions on evidence-based medicine, aligning these decisions housing constitutional principles that the right to health and the scientific conclusions of efficacy, effectiveness and efficiency in oncology drugs, when compared to the treatments offered by SUS

As práticas exitosas de leitura no ensino fundamental: vozes sociais de professores e de estudantes

The school is the social place which should provide the formation of critical readers. In this context, the role of the teacher is crucial when it comes to teaching reading. Thus, this doctoral research aims to explicit the reading practices evidenced from social voices of teachers and Fundamental School students from state public schools at RN that have successful results, according to IDEB 2009. Moreover, we seek to explicit, through the positions of teachers, the conceptions of reading underlying their reading activities, as well as elucidate the social voices related to teaching of reading that are present in the National Curriculum Guide for 9 years Fundamental School and in the Political-Pedagogical Projects of the educational institutions investigated. In order to accomplish this goal, we carried out observations in the classroom, applied questionnaires with teachers and students in the 9th grade of Fundamental School, in classes of Portuguese Language, and also performed dialogical meetings with the management and pedagogics schools teams. The theoretical foundation that guides the research comes from bakhtinian thinking (2009, 2010), which addresses the dialogical perspective of language and active responsive comprehension. Furthermore, this work is anchored in theoretical reflections of Antunes (2005, 2009) and Geraldi (2003, 2006, 2010) about the reading and writing in the country, which contribute to the resizing of the teaching and learning process of Portuguese Language. This study belongs to the field of Applied Linguistics, which investigates language as social practice in the context of learning mother language or in contexts where relevant questions about the use of language are evidenced. The parameters of qualitative research in a social-historic perspective are adopted seeking to understand the school context by the subjects involved in research. The research corpus is composed of: (i) information constructed through the use of questionnaires with teachers and students; (ii) information constructed from the observed lesson and dialogue with management and pedagogical teams; (iii) a set of selected information, i.e., empiricism built through documentary analysis of the National Curriculum Guide for 9 years Fundamental School (CONSELHO NACIONAL DE EDUCAÇÃO, 2010) and the Political- Pedagogical Projects of the investigated schools. The analysis of the sayings of teachers and students suggest reading practices from various texts, in particular, from the literary sphere, in activities involving discussions, reading and reading comprehension exercises, interviews, songs, seminars organizations, concerts, dramatizations, literary weeks, among other practices. Furthermore, these analyses reveal that teach Portuguese Language requires commitment, responsibility and satisfaction, as well as more grounded theoretical principles, which make teaching practice more efficient. The research also reveals that the success of the teaching-learning process occurs by virtue of the involvement of school s segments in the educational process, creating therefore a network of responsibilities. In this sense, this research may contribute to the production of knowledge that can guide and enrich the teaching and learning of reading, envisioning a pedagogical practice constructed from the relationship with the other, i.e., from the dialogism which provides formation of young people that exercise their citizenship

Seed lipases: sources, applications and properties - a review

This paper provides an overview regarding the main aspects of seed lipases, such as the reactions catalyzed, physiological functions, specificities, sources and applications. Lipases are ubiquitous in nature and are produced by several plants, animals and microorganisms. These enzymes exhibit several very interesting features, such as low cost and easy purification, which make their commercial exploitation as industrial enzymes a potentially attractive alternative. The applications of lipases in food, detergents, oils and fats, medicines and fine chemistry, effluent treatment, biodiesel production and in the cellulose pulp industry, as well as the main sources of oilseed and cereal seed lipases, are reviewed.

Solids rheology for dehydrated food and biological materials

Mechanical properties of food products and biological materials are greatly affected by the drying process and are considered one of the most important quality attributes of dehydrated products. The aim of this work was to review theoretical principles and mathematical modeling, analyzing the measurement techniques and major experimental results that exist in the literature about rheological properties of dehydrated foods and biological materials. Different methods of measuring rheological parameters (fundamental and empiric or imitative) are discussed and major experimental results, as well as the rheological models used in their analysis, published in recent years are presented.

Gravity and the quantum: Are they reconcilable?

General relativity and quantum mechanics are not consistent with each other. This conflict stems from the very fundamental principles on which these theories are grounded. General relativity, on one hand, is based on the equivalence principle, whose strong version establishes the local equivalence between gravitation and inertia. Quantum mechanics, on the other hand, is fundamentally based on the uncertainty principle, which is essentially nonlocal. This difference precludes the existence of a quantum version of the strong equivalence principle, and consequently of a quantum version of general relativity. Furthermore, there are compelling experimental evidences that a quantum object in the presence of a gravitational field violates the weak equivalence principle. Now it so happens that, in addition to general relativity, gravitation has an alternative, though equivalent, description, given by teleparallel gravity, a gauge theory for the translation group. In this theory torsion, instead of curvature, is assumed to represent the gravitational field. These two descriptions lead to the same classical results, but are conceptually different. In general relativity, curvature geometrizes the interaction while torsion, in teleparallel gravity, acts as a force, similar to the Lorentz force of electrodynamics. Because of this peculiar property, teleparallel gravity describes the gravitational interaction without requiring any of the equivalence principle versions. The replacement of general relativity by teleparallel gravity may, in consequence, lead to a conceptual reconciliation of gravitation with quantum mechanics. © 2006 American Institute of Physics.

Estilos e estratégias de aprendizagem do inglês: um estudo de caso no ensino fundamental

Este estudo tem como objetivo investigar os estilos de aprendizagem de aprendentes de uma turma do Ensino Fundamental de uma escola pública municipal de Belém e as estratégias de aprendizagem utilizadas por eles nas aulas de inglês e também fora delas. Além disso, buscamos identificar os objetivos dos aprendentes com relação à aprendizagem de inglês. Foram adotados os princípios da pesquisa qualitativa estudo de caso para coleta e análise de dados. Os instrumentos utilizados foram questionários, auto-relatos verbais e notas de campo. As propostas de Brown (1994), Felder e Soloman (1993) e Oxford (2003) forneceram suporte teórico para uma tentativa de classificação dos estilos de aprendizagem. Escolhemos as teorias de Oxford (1990) para descrever e classificar as estratégias. Para tornar a aprendizagem de uma LE mais eficaz na escola pública, exploramos a possibilidade de propor uma instrução baseada em estratégias integrada ao conteúdo do curso regular. Com esse objetivo, apresentamos dois modelos: Instrução Baseada em Estratégias (IBES) de Cohen (1998) e o Modelo de Treinamento de Estratégias Oxford (1990). Nossos resultados descrevem os estilos e estratégias de aprendizagem dos alunos de uma turma da 8 série do Ensino Fundamental. Aventamos a possibilidade de que, identificadas essas características, professor e alunos podem criar situações de aprendizagem muito mais eficazes.

LABEXP - Laboratório de experimentação remota em tempo real

Este trabalho apresenta o processo de desenvolvimento e implementação do Laboratório de Experimentação Remota em Tempo Real (LabExp), atualmente em funcionamento na Universidade Federal do Pará, com o objetivo de funcionar como uma plataforma auxiliar para ensino e aprendizagem das disciplinas de sistemas de controle. O ensino e aprendizagem foram contemplados através da disponibilização de experimentos, onde os usuários poderão interagir com os mesmos, alterando parâmetros e observando o resultado desta interação. Além dos experimentos disponíveis, acredita-se que em ambientes de educação online é interessante disponibilizar aos alunos ferramentas que proporcionem maior interação entre alunos e professores e com o próprio laboratório remoto, proporcionando uma metodologia de aprendizado mais colaborativo, estimulando o aluno. Desta forma, são disponibilizadas aos alunos três aplicações: uma para envio de seus próprios experimentos; outra para interação com outros alunos, através de um fórum; e outra para o envio de suas opiniões/críticas. Antes do processo de desenvolvimento e implementação do LabExp, foi realizada uma análise sucinta sobre educação online, tendo em vista ser esta a finalidade do laboratório. Esta análise proporcionou maior conhecimento sobre esta metodologia de educação, orientando no restante do desenvolvimento do LabExp. Compreende-se que as tecnologias utilizadas não são determinantes para o desenvolvimento de um laboratório remoto, voltado para a educação online, entretanto experimentos remotos de sistemas de controle possuem uma restrição temporal, ou seja, necessitam obedecer a limites de tempo restritos, funcionando em tempo real. Para conseguir este comportamento foi utilizada a Real-Time Application Interface (RTAI), com o componente RTAI-XML. Além das tecnologias utilizadas, neste trabalho também é apresentado o processo de modelagem do LabExp, de acordo com padrões, princípios e recursos da Unified Modeling Language (UML) aplicada a aplicações web. Este processo de modelagem foi de fundamental importância, pois facilitou e orientou o desenvolvimento do laboratório.

A exigibilidade judicial do direito fundamental à educação na Constituição Federal de 1988

O presente estudo tem como objeto analisar a efetividade do direito à educação na Constituição de 1988. Examina-se o conceito, a natureza, os custos (como a criação de reserva de fundos no FUNDEB e as designações sobre os percentuais a serem usados para a manutenção e desenvolvimento do ensino pelas entidades federativas), o papel do Estado e da sociedade e os princípios constitucionais que regulam a implementação do direito à educação na realidade brasileira. A partir do postulado de que o Estado Social e Democrático de Direito é protetor dos direitos sociais, foi relevante considerar que os argumentos sobre o mínimo existencial e a escassez de recursos devem ser apreciados com o máximo de cuidado. Além disso, são analisadas duas decisões judiciais proferidas em dois casos concretos que foram levados ao Supremo Tribunal Federal, fenômeno denominado por maior parte da doutrina de “judicialização de políticas públicas”, trata-se do caso Santo André/SP e do caso Queimados/RJ. Por fim, as referidas decisões são analisadas conforme os princípios e valores constitucionais tendo sido concluído que as demandas coletivas de satisfação do direito à educação são prioritárias em relação as demandas individuais, embora ambas sejam exigíveis.
