A regulação da economia da inovação: patentes e biodiversidade no desenvolvimento dos países do trópico úmido

Esta dissertação apresenta uma análise da regulação da inovação em países do Trópico Úmido. A questão norteadora é como estes países lidam com a regulação da propriedade industrial nas suas políticas de inovação e como eles incorporam sua rica biodiversidade neste contexto. Propriedade intelectual – particularmente patentes – fornece uma ampla discussão nas políticas de inovação, contudo, também indicam como as questões da biodiversidade são negligenciadas pelos governos ao estabelecer seu caminho de convergência para o desenvolvimento. O estudo selecionou alguns países do Trópico Úmido que são conhecidos por seus esforços de convergência e de grande biodiversidade, são eles: Brasil, China, Cingapura, Filipinas, Índia, Indonésia, Malásia, México, Tailândia, Taiwan e Vietnã. Os dados coletados nas bases de dados de patentes da Organização Mundial da Propriedade Intelectual – OMPI mostram que esses países fazem pouco uso de patentes para a proteção da biodiversidade. O conhecimento científico sobre a riqueza de espécies e sua apropriação pela sociedade é limitada. Isso pode ocorrer quando a biodiversidade não é vista pelas instituições do Trópico Úmido como um ativo crucial. Argumenta-se que os países devem concentrar seus investimentos em P&D em ativos específicos, portanto, nós acreditamos que isso se aplica para a biodiversidade. Fazendo uma análise dos sistemas de patentes de regulamentação desses países selecionados, verificou-se que os requisitos básicos de uma patente são padronizados. Nossa análise sugere que os países do Trópico Úmido redirecionem a sua proteção da propriedade intelectual, a fim de que as inovações futuras destaquem os ativos específicos da região. Além disso, um projeto cuidadoso de leis sobre esses direitos é necessário, levando em conta os aspectos econômicos, sociais e ambientais. A divulgação das vantagens locais através da análise da intensidade da apropriação da biodiversidade por meio do sistema de patentes, bem como a comparação entre a dinâmica das leis de patentes dos países no sistema de inovação, pode orientar as decisões institucionais em relação ao desenvolvimento tecnológico regional.

Políticas públicas, corredores de exportação, modernização portuária, industrialização e impactos territoriais e ambientais no município de Barcarena, Pará

Este artigo discute as dinâmicas de aglomeração industrial, incremento e modernização portuária no município de Barcarena, Estado do Pará, Brasil. Especificamente, discute as causas estruturais que explicam estas dinâmicas, e as mudanças qualitativas e quantitativas locais, acerca dos aspectos espaciais, sociais, demográficos e ambien-tais. Diferentes momentos de produção e exportação de produtos minerais (caulim, bauxita e produtos originados dela – alumina, alumínio) na Amazônia Oriental Brasileira levam a instalação, consolidação e expansão de um distrito industrial e portuário em Barcarena. Na atual década, Barcarena integra um corredor de exportação diretamente ligado a eixos ou sistemas produtivos nacionais e globais. Contudo, as dinâmicas que sustentam este crescimento econômico não apontam para perspectivas de que a produção conduza ao enraizamento social do desenvolvimento, ao estabelecimento de vantagens competitivas que tenham uma base sistêmica; tampouco contribui para a reversão dos impactos sociais e ambientais.

Support area as an indicator of environmental load: Comparison between Embodied Energy, Ecological Footprint, and Emergy Accounting methods

Environmental aspects have been acknowledged as an important issue in decision making at any field during the last two decades. There are several available methodologies able to assess the environmental burden, among which the Ecological Footprint has been widely used due to its easy-to-understand final indicator. However, its theoretical base has been target of some criticisms about the inadequate representation of the sustainability concept by its final indicator. In a parallel way, efforts have been made to use the theoretical strength of the Emergy Accounting to obtain an index similar to that supplied by the Ecological Footprint. Focusing on these aspects, this work assesses the support area (SA) index for Brazilian sugarcane and American corn crop through four different approaches: Embodied Energy Analysis (SA(EE)), Ecological Footprint (SA(EF)), Renewable Empower Density (SA(R)), and Emergy Net Primary Productivity (SA(NPP)). Results indicate that the load on environment varies accordingly to the methodology considered for its calculation, in which emergy approach showed the higher values. Focusing on crops comparison, the load by producing both crops are similar with an average of 0.04 ha obtained by SA(EE), 1.86 ha by SA(EF), 4.24 ha by SA(R), and 4.32 ha by SA(NPP). Discussion indicates that support area calculated using Emergy Accounting is more eligible to represent the load on the environment due to its global scale view. Nevertheless, each methodology has its contribution depending of the study objectives, but it is important to consider the real meaning and the scope of each one. (C) 2012 Elsevier Ltd.

Eficiência Energética e sustentabilidade em edificações: um estudo de caso na biblioteca da UNESP de Guaratinguetá

Energy efficiency has gained significant importance in recent years, mainly due to cyclical climatic conditions and current supply of natural resources. The present work deals with the procedures and requirements necessary to evaluate a building to a level of efficiency corresponding to your project and the actual implemented. To perform this analysis, we adopted the technical regulation efficiency prepared by Procel along with other agencies of the sector. The Regulation aims to create a model for the technical evaluation of the efficiency of buildings, popularize and expand the theme specification of conditions drawn up today. The building analyzed in this study was the library of UNESP, Guaratinguetá. Still, after the completion of the final efficiency analysis, are presented proposals for intervention that can improve and enhance the present situation of the building. The interventions are based on many technical factors and local conditions of climate and supply of resource. The issue of sustainability was explained in order to serve as a tool to expand the options available to upgrade a building in front of their impact on the environment

Desenvolvimento regional e sustentabilidade: a indústria intensiva em recursos naturais na região administrativa de Ribeirão Preto

The natural resource intensive industries have moved from center to periphery in Brazil. This shift is related to the environmental impacts generated by this type of industry, as occur biggest benefits to these industries in small towns as tax exemptions and donations of land, and local institutional capacity is lower in pollution control. In the 1970s began, in the state of São Paulo, a process of industrial deconcentration of Metropolitan Region of São Paulo to the inside of state, which generated an intense industrialization of the region of Campinas, Ribeirão Preto, Sorocaba e São José dos Campos. This process of industrial deconcentration had support in state policies restricting new industries in the Metropolitan Region and the creation and financing of infrastructure and improvement of road. This research project aims to verify whether there has been a shift of natural resource intensive industries for the Administrative Region of Ribeirão Preto, as well as aspects of the sustainability of this process

Certificações ambientais para construções civis

Over the recent human history within the last centuries the environmental degradation has been accumulating and growing rampantly causing effects today easily perceived by all. Because of this, today we can say that there is almost a consensus among the world population's concern with the environment in order to seek to minimize these effects immediately in addition to not aggravate the situation for future generations. Thus today it is common to find a wide range of products with this ideal of sustainable commitment in the various commercial areas. The construction industry has a responsibility to be a major cause of these impacts to the environment, so it is also one of the main vectors able to mitigate the degradation of the environment. In order to encourage, oversee and promote the sustainable attitudes within the construction area emerged environmental certifications. In this work it's exposed some of the major certifications for civilian buildings, highlighting the Selo Azul da Caixa that appears as a good choice focused on the Brazilian reality

EDiferentes tipologias de edificação e o ser sustentável mediante o LEED e o CBCS

The principles and dimensions of sustainability concept is increasingly gaining ground within the building industry. Over the past decades, its applicability within the different environments and for different buildings typologies have been study to attend better the present populations and future generations. It is within this scenario that international certifications started to appear. The most famous and developed one being LEED certification system. In Brazil, as a support to the certification and also sustainability practices and conducts, was founded the Brazilian Council for Sustainable Construction (CBCS). The council and the certifications have the objective to disseminate and generate awareness to reduce energy and water consumption, aiming for life quality. Many constructions around de country have already the international certification, which also boost the rise of national certifications with specific criteria for the national context. However, such certificates are mainly destiny for medium and high standard buildings, often as a commercial advantage to explain the high costs. The purpose of this work is to be able to define what is being sustainable in the construction industry, taking for basis, LEED and CBCS. In addition, since there is a significant increase in the production of Housing Social Interest, the other angles will be to analyze how to apply the practices and sustainable technologies for low-cost projects with the objective to balance the three dimensions of sustainability: environmental, social and economics.

Preparation of Coated Microtools for Electrochemical Machining Applications

PREPARATION OF COATED MICROTOOLS FOR ELECTROCHEMICAL MACHINING APPLICATIONS Ajaya K. Swain, M.S. University of Nebraska, 2010 Advisor: K.P. Rajurkar Coated tools have improved the performance of both traditional and nontraditional machining processes and have resulted in higher material removal, better surface finish, and increased wear resistance. However, a study on the performance of coated tools in micromachining has not yet been adequately conducted. One possible reason is the difficulties associated with the preparation of coated microtools. Besides the technical requirement, economic and environmental aspects of the material and the coating technique used also play a significant role in coating microtools. This, in fact, restricts the range of coating materials and the type of coating process. Handling is another major issue in case of microtools purely because of their miniature size. This research focuses on the preparation of coated microtools for pulse electrochemical machining by electrodeposition. The motivation of this research is derived from the fact that although there were reports of improved machining by using insulating coatings on ECM tools, particularly in ECM drilling operations, not much literature was found relating to use of metallic coating materials in other ECM process types. An ideal ECM tool should be good thermal and electrical conductor, corrosion resistant, electrochemically stable, and stiff enough to withstand electrolyte pressure. Tungsten has almost all the properties desired in an ECM tool material except being electrochemically unstable. Tungsten can be oxidized during machining resulting in poor machining quality. Electrochemical stability of a tungsten ECM tool can be improved by electroplating it with nickel which has superior electrochemical resistance. Moreover, a tungsten tool can be coated in situ reducing the tool handling and breakage frequency. The tungsten microtool was electroplated with nickel with direct and pulse current. The effect of the various input parameters on the coating characteristics was studied and performance of the coated microtool was evaluated in pulse ECM. The coated tool removed more material (about 28%) than the uncoated tool under similar conditions and was more electrochemical stable. It was concluded that nickel coated tungsten microtool can improve the pulse ECM performance.

Fast and accurate numerical solutions in some problems of particle and radiation transport: synthetic acceleration for the method of short characteristics, Doppler-broadened scattering kernel, remote sensing of the cryosphere

The aim of this work is to present various aspects of numerical simulation of particle and radiation transport for industrial and environmental protection applications, to enable the analysis of complex physical processes in a fast, reliable, and efficient way. In the first part we deal with speed-up of numerical simulation of neutron transport for nuclear reactor core analysis. The convergence properties of the source iteration scheme of the Method of Characteristics applied to be heterogeneous structured geometries has been enhanced by means of Boundary Projection Acceleration, enabling the study of 2D and 3D geometries with transport theory without spatial homogenization. The computational performances have been verified with the C5G7 2D and 3D benchmarks, showing a sensible reduction of iterations and CPU time. The second part is devoted to the study of temperature-dependent elastic scattering of neutrons for heavy isotopes near to the thermal zone. A numerical computation of the Doppler convolution of the elastic scattering kernel based on the gas model is presented, for a general energy dependent cross section and scattering law in the center of mass system. The range of integration has been optimized employing a numerical cutoff, allowing a faster numerical evaluation of the convolution integral. Legendre moments of the transfer kernel are subsequently obtained by direct quadrature and a numerical analysis of the convergence is presented. In the third part we focus our attention to remote sensing applications of radiative transfer employed to investigate the Earth's cryosphere. The photon transport equation is applied to simulate reflectivity of glaciers varying the age of the layer of snow or ice, its thickness, the presence or not other underlying layers, the degree of dust included in the snow, creating a framework able to decipher spectral signals collected by orbiting detectors.

Bedouin in the Negev and Environmental Studies: Current and Future Research Prospects

Environmental aspects are increasingly being integrated in Negev Bedouin studies by both, NGO activists and scholars. We will present these recent works and discuss new concepts and methodologies of environmental studies with potential relevance in the field of Negev Bedouin studies. We will then identify research areas where environmental and development approaches converge or diverge with mainstream social sciences on this specific field of research. While most of the Bedouin population in southern Israel lives in urban centers in the Northern Negev, a large part of Bedouin people live in unrecognized clusters of houses in remote areas. Extensive livestock rearing is an important source of livelihood at least for non-urbanized Bedouin, the latter forming the lowest economic strata of the Israeli spectrum of incomes. Numerous stressors affect this Bedouin community enduring uncertain livelihood and access to land. The erratic precipitations from year to year and long-term changes in precipitation trends are a source of great uncertainty. With a significant price increase for feeding supplements to compensate for dry years, livestock rearing has become a harsher source of livelihood. Land scarcity for grazing adds to the difficulty in ensuring enough income for living. Studies in the last 15 years have described several livelihood strategies based on a livestock rearing semi-nomadic economy in the Negev. A number of other analyses have shown how Bedouin herders and governmental agencies have found agreements at the advantage of both, the agencies and the herders. New concepts such as transformability, resilience and adaptation strategies are important tools to analyze the capacity of vulnerable communities to cope with an ever increasing livelihood uncertainty. Such research concepts can assist in better understanding how Bedouin herders in the Negev may adapt to climate and political risks.
