This presente monograph propose the analysis and discussion of the production of urban space and the processes of their structuring intraurbana from the dynamics of the real estate market into three Medium-sized Cities, Campina Grande - PB, Mossoró - RN and Passo Fundo - RS, whereas the various agents producing this space, in a comparative perspective. From this urban dynamic search to analyze the processes and relations present in these spaces, which are important for its production. From the compilation of real estate advertisements in local newspapers, are analyzed offerings of urban land, houses and apartments in each one of these cities by highlighting their locations and differentiated prices. Thus, working with data from real estate ads from the period 1995 - 2010 and a comparative perspective of the characteristics of real estate markets of three medium-sized cities, it tried to apprehend processes that are common between them and other individuals, to each one. Therefore the comparative analysis developed in this monograph sought to verify whether there are similarities between the cities in relation to the trends of concentration/spatial dispersion of bids and movements throughout time, in addition to a further intensification of the activities of real estate agents in face of such trends and offerings. In addition, we sought to remove a set of problematization that allow them to understand with more acute, in this set of medium cities of Brazilian urban network, processes of change that is already being discussed in the recent period by ReCiMe.

Currently the world is under an energy revolution, every day more technologies are developed in order to better use the energy for having better energy efficiency of equipment and processes with minimal environmental degradation. Taking into account that thousands of people live in built environments in the context of cities and that the energy flow to this location is significant, it is important to study the built environment as a potential source of savings, energy recovery and regeneration, because cities are the major bottlenecks energetic. Therefore, this study aimed to examine and to list the most important and promising technologies to be used in the built environment to collect or save energy that would be wasted, such as clothes that generate energy through movement or solar incidence, facades of buildings that generate energy due to solar radiation, fitness centers that produce electricity due to the rotation used in fitness equipment for athletes, elevators that take advantage of the potential energy or use it more rationally, generators that take advantage of energy vibrational, and finally more sustainable vehicles with higher performance and less degrading the environment. The information and results obtained from this study show that the technologies used to harness energy before lost are increasingly evident and also is increased the progress relative to the energy use in a urban context. In the closure, a comparison of energy expenditure between a city that uses some of these sustainable technologies and another of the same size with conventional habits is presented

Estudou-se a anatomia de Spathanthus, Rapatea, Cephalostemon e Duckea pertencentes à tribo Rapateeae (Rapateoideae, Rapateaceae), buscando levantar caracteres úteis para a taxonomia. Todas as espécies estudadas apresentam células epidérmicas com a parede periclinal externa levemente espessada e feixes de fibras subepidérmicos em ambos os órgãos; feixes vasculares na região mediana da folha, com bainha de fibras conspícua no floema; e escapos com idioblastos contendo compostos fenólicos na epiderme e no parênquima, que são características que suportam a tribo. O formato do escapo em secção transversal diferencia os gêneros, enquanto a forma e estrutura da nervura central do limbo foliar tem valor diagnóstico. São características exclusivas de Spathanthus: células epidérmicas com corpos silicosos com distribuição aleatória e parênquima clorofiliano plicado no limbo foliar; e presença de feixes de fibras no mesofilo e no parênquima do escapo. Spathanthus distingue-se também pelo número, tipo e distribuição dos feixes vasculares no escapo. O gênero Rapatea caracteriza-se pela presença de estômatos e células com corpos silicosos apenas na epiderme abaxial das folhas e pela presença de parênquima clorofiliano braciforme no limbo foliar. Rapatea paludosa distingue-se por apresentar folha com extensão da bainha dos feixes vasculares em ambas as faces da epiderme e escapos com alas desiguais, enquanto Rapatea ulei apresenta escapos com alas do mesmo tamanho e tricomas contendo compostos fenólicos. São caracteres com valor diagnóstico para Cephalostemon riedelianus: células epidérmicas com paredes retas em vista frontal e escapo com córtex definido, cordões esclerenquimáticos subepidérmicos voltados aos feixes vasculares maiores e medula fistulosa

Este trabalho trata das cidades médias, em particular das cidades de Marília, São José do Rio Preto, Londrina e Mossoró. Dentro desse estudo, o enfoque se dá para a compreensão e análise sobre o modo como estão combinados os espaços não edificados e os vazios urbanos, os espaços construídos e as vias de circulação e suas transformações ao longo do tempo. A proposta é analisar o processo de expansão do tecido urbano dessas cidades para compreender sua morfologia, bem como procurar fazer uma reconstituição, tomandose a dimensão espacial e temporal, com o intuito de que esta contribua na conferência das identidades próprias de cada cidade, viabilizando a identificação das semelhanças entre elas, como também de suas especificidades. Durante o desenvolvimento do trabalho procuramos identificar elementos promotores da reestruturação urbana pela qual as cidades têm passado nas ultimas décadas, tentando relaciona-los com as novas formas de produção e organização espaciais...

The paper presented is aimed at analyzing the core functions of Presidente Prudente by demand and scope determined by the supply and distribution of goods and services (jobs and educational institutions). For this purpose, we tried to explore the daily flows of people from cities in agglomeration process with Presidente Prudente, as well as other more distant locations, forming what is recognized as Commuting movements. The core functions of medium-sized cities have increased significantly in the Brazilian urban network, spatial interactions occurring in these spaces with more intensity in metropolises. At the core of this research was undertaken literature review on the subject and preliminary surveys data, especially the data in the study called Region of Influence of Cities - Regic-IBGE, revealing joints between the various urban spaces analyzed. This research is developed in level undergraduates and was funded by CNPq and currently FAPESP

CARL FRIEDRICH PHILIPP VON MARTIUS foi um naturalista alemão que visitou diversas regiões brasileiras, sobretudo a região da Amazônia. Este veio ao Brasil junto com a comitiva da Arquiduquesa Leopoldina da Áustria, que aqui vinha se casar com o Príncipe Herdeiro D. Pedro de Alcântara, futuro Imperador do Brasil. A sua viagem pelo Brasil teve início em 1817, no Rio de Janeiro, e término em 1820, na região amazônica. Estima-se que coletou amostras de cerca de 7.200 espécies de plantas, que foram base para a produção da Flora Brasiliensis, editada inicialmente por ele, com a colaboração e edição póstuma de AUGUST WILHELM EICHLER e IGNATZ URBAN. Esta obra monumental foi publicada entre 1840 e 1906, com a participação dos mais eminentes botânicos europeus da época, que realizaram os tratamentos taxonômicos de 22.767 espécies brasileiras, na maioria angiosperma. O tratamento das Lauraceae ficou a cargo do botânico suíço CARL DANIEL FRIEDRICH MEISSNER. Dentre as espécies de Lauraceae constam 64 táxons com indicação de coletas realizadas por MARTIUS. Tomando-se por referência o tratamento de MEISSNER, bem como as demais opera principes, o presente trabalho teve como objetivo a atualização taxonômica das espécies de Lauraceae coletadas por MARTIUS no Brasil. Para tanto, foram verificadas as coleções dos principais herbários europeus e norte americanos, com base na literatura especializada e nos bancos de dados disponíveis. Através de imagens em alta resolução dos espécimes, esses foram confrontados com os protólogos e revisões dos gêneros. Desta forma, os tratamentos das espécies envolvidas foram conduzidos com a verificação do status taxonômico das mesmas, suas sinonímias, nomes atualmente aceitos como corretos, bem como sobre as tipificações relacionadas. Sempre que pertinente, foram feitos comentários sobre as coleções e sobre problemas taxonômicos e nomenclaturais detectados. Com este trabalho...

The intensive development in the urbanization process implied a series of economic, social, and gradually, environmental transformations, essentially, since its intensification, which took place from the Industrial Revolution in Europe and North America. In Latin American countries, including Brazil, there was such acceleration in urban sprawl, only in the middle of the twentieth century, fomented by a peculiar industrialization, coming from the scientific-technical revolution, which occurred in developing countries. In this context, and with a lack of planning and an effective organization, cities of the dependent countries face an inordinate population growth and an unprecedented industrial swelling. Brazil, following this trend, presents several issues regarding the gaps in the provision of necessary infrastructure to meet the most basic needs of its population and the intense activity and anthropogenic effects on the environment. In this sense, environmental problems, related to air and water pollution, degradation and contamination of soil, paving roads, reduction of green areas, urban heat island, among others, reaching ever deeper into the Brazilian urban areas. It is important the analysis in this final project, the weather events related to episodes of strong winds and the events and the impacts to the population of Rio Claro (SP) in the period 2005 to 2010, basing themselves in Geographical Climatology and Urban climate studies. In this scenario, we found the prevalence of occurrences linked to falling trees in the study area, connected, at the same time, to the occurrence and to the absence of episodes of extreme events, with measurements of strong winds, showing a connection between the events and external facts to episodes of winds

The climate is one of the main elements of the natural environment that governs the life of man. Specific conditions of temperature, humidity, light, wind and precipitation have direct influence on physiological conditions that man needs to survive and more than that, besides the influence on human and animal physiology, the climatic elements are also responsible for a significant portion of economic activities such as industry, agriculture, commerce, transportation, and others. Therefore, any change in weather patterns has great impact on daily activities, and even more in urban sites, where the most of population is concentrated nowadays. Based on this discussion and concerned in understand the atmospheric structure, this monograph intends to analyze the pattern of atmospheric and temperature element in seven cities of small and medium size located in the state of São Paulo countryside...

Esta pesquisa tem como objetivo de examinar as estratégias de expansão das firmas brasileiras do setor de carnes (bovina, suína e avícola) para além das fronteiras nacionais a partir da literatura sobre internacionalização de empresas. Essa literatura aponta fatores como a origem do capital, o grau de internacionalização da empresa, o setor de atuação, entre outros, como importantes condicionantes que afetam esse processo. No entanto, vários desses fatores não são diretamente aplicáveis aos casos brasileiros, caracterizado por uma internacionalização tardia e, em alguns casos, rápida. Para este estudo foram selecionadas três empresas nacionais do setor de carnes que apresentam diferentes estágios de internacionalização: JBS-Friboi, Marfrig, Brasil-Foods (Perdigão e Sadia). As informações selecionadas sobre cada empresas foram reunidas em dossiês corporativos, e analisadas através de estudos de casos, permitiram examinar e comparar as estratégias globais das empresas. Os resultados permitem concluir que as duas primeiras empresas demonstram uma estratégia agressiva de internacionalização (em certa medida a primeira fazendo o papel de líder e a segunda de seguidora e, por isso, complementares em posicionamento nos diferentes mercados regionais), enquanto a terceira se mantém nas etapas iniciais desse processo, fortemente vinculadas às exportações a partir do Brasil

The oil market is not a common market, and its complexity increases dramatically when considering the strategic and geopolitical involved, thus resulting in large uncertainties and concerns. The attempt to control prices has always been a challenge for the major world powers, since the increase in oil prices benefits the exporting countries, but harms importers, especially those regarded as less developed. Understand and try to predict some strategies adopted up the oil crises is one of the main points of the research, in order to demonstrate how economics can be used as an instrument of power and domination between nations, and how plans and strategies and rearrangements of supply and demand favor the growth of this economy, especially in the current period, with the new Brazilian oil era, beginning with the discovery of pre-salt, amid a context of growing need for the use of oil and its derivatives

Water is one of the main inputs in agribusiness and is traded indirectly through the sale of agricultural products such as orange (juice or fresh) and cane sugar (ethanol and refined sugar). This study aims to estimate the proportional mass of water present in the products exported in the form of agricultural commodities considering the amount of water incorporated into the product in its genesis by plant photosynthesis, reinforcing a reflection on virtual and real water export, as well to indicate subsidies to management, planning and taxing of water resources

The study aims at analyzing the potential impacts of environmental labeling programs, emphasizing the European Community program on Brazilian exports to the EU. For this, we traced the historical growth of bilateral relations between the EU and Brazil, which shows a strategic partnership, and then it was listed trade barriers (tariff and nontariff) imposed by these two markets to the international trade relations. Later, the emergence of environmental seals was discussed, as well as their potential barriers to trade. Finally, selected products were analyzed in order to know the potential effects of environmental labeling on products exported by Brazil

Since the middle of the XX century, observed a guided development in capitalism and globalization. In this context, a new way of thinking and producing dwellings, closed horizontal residential condominiums, with its beginnings in the United States. Currently, these also appear as a trend in Brazil. Their deployment has generated both social and spatial problems, since the production and consumption of urban space are given in different ways in different social classes. This process began in the 1970s and was unique to metropolitan areas until the 1980s, when it began to achieve medium-sized cities. Thus, highlighting some points, such as the production and consumption of urban space and the construction of condominiums in average Brazilian cities, this paper aims to describe and analyze the dynamics of residential condominiums in the city of Itu (SP)
