There are substantial evidences that the period experienced by humanity globally is unprecedented and is heading towards a major transformation that results from the Globalization. Totally conditioned to the addictions of the dominant and predatory capitalism, humanity has, for decades, exhausted natural resources, disregarded the nature of its own social existence and walked away from its humanity. It is notable, however, an impressive flow of factors that dialogue and support each other as trends that go towards sustainable development, based on the harmonious integration between Technology, Culture, Society, Environment and Economy. This emerging moment can be seen from the perspectives of the Creative Economy as economic paradigm centered on the subjectivity and the human capacity to undertake innovative services, products and solutions guided by social values. Within this fluid and dynamic global context, initiatives that legitimately intend to act sustainably are gaining space. This socioeconomic moment fosters and is fostered by new kinds of work and organization guided by the Collaboration and social structuring on Network Patterns. These new social models significantly transform the understanding and insights about the Communication flows. The HUB São Paulo, as creative and social organization that operates under the logic of Collaboration through a Network Structure, was the subject of a case study used to sustain the defense of this emerging scenario and also to perform an analysis on the new role of Communication, at perspectives of transformation of mental paradigms towards sustainability and establishment of meaningful connections

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

Man can transform the nature according to their needs through technique which enables agriculture, cattle raising, constructions of buildings for housing, transport routes, etc. This action has brought significant transformations to the environment, and relief is one of the most changed elements, mainly at urban areas, which concentrates most of the Brazilian population. In these areas geomorphologic systems have undergone alterations in their flow of matter and energy by the action of man. Thus, it is possible o understand the action of man as geomorphologic action, nowadays, the tecnógeno, since the human action can interfere qualitatively and quantitatively in the input and output of these systems. The anthropic geomorphology has contributed to the analyses of the effects due to the urbanization at the form and at the geomorphologic process in the urban watersheds, indicating the transformations at the shape of the relief and the alterations due to the acceleration of the flow of matter and energy. From these questions, this study had the main diagnose the anthropogenic changes of the relief at the basin of Corrego do Jardim São João, Araras (SP), comparing two scenes, 1997 and 2006, through geomorphological mapping evolutionary in the area. The geomorphological feature altered at the basin are directly linked to the use of soil, mainly at the urban use, which caused effects in the relief at the studied area, making possible to define periods of the urban evolution and impacts caused by the urbanization. Among the changes it was found the decrease of the topographic breaks and at the riverbed channels, as the increase of the accumulation of the plain and riverbed terrace. The elaboration of a letter of the legal restrictions of the basin make possible to evaluate some of the environmental urban problems that occur, which are due to the occupation of the relief in the areas of permanent preservation that brings significant impacts to...

The use of heat in parallel with relative low temperatures and applied to several areas of the industry is essential for the main manufacturing processes, like drying, dehydrating, concentration, annealing, production of chemical reactions, and microbiological sterilization. Without neither the heat nor the coming of a great quantity of thermal heat, with high quality, there would not be the “modern society”, with its high standards of living plus its high consumption levels; from services to goods in general. Within an almost absolute way, the heat flows are obtained from vapor systems. Thus, in this work we are going into the operation of a vapor system, composed of two firetube boilers dimensioned to supply vapor for three processes. However, with the transfer of one of the processes to another plant, the system got over-dimensioned. But, taking advantage of this scenario, the two boilers were used to supply vapor to further processes, causing their intermittent usage. Moreover, the operational alternative adopted by the maintenance engineering of the plant for a creating a solution has been presented; both the positive points and negative ones were disclosed, likewise the possibility of improvement points

The flux of Bolivian migrants to the city of São Paulo had its beginning in the 1950 decade, following bilateral agreements between Brazil and Bolivia, and was intensified since the beginning of 1980 decade, when existed a necessity of manpower in the textile sector of the city. The migratory fluxes previously stemmed of the North and Northeast regions of the country become less intense, having then the entrance of migrants coming from neighboring countries, the so called South Cone. The Bolivians leave their country in the search for better life conditions and find in São Paulo the possibility to insert them in the biggest concentration of financial capital in the Latin America. The objective of this research is to analyze the arrival of the Bolivian migrants to the city, having its locus of analysis the Brás region and the reflection about the foreigners that influenced the modification of the structure, both territorial and cultural, of the district and how is the relation between the Bolivians and the habitants previously established there

The term model refers to any representation of a real system. The use of models in Hydrogeology can be valuable predictive tools for management of groundwater resources. The numeric models of groundwater flow, object of this study, consist on a set of differential equations that describe the water flow in the porous medium. In this context, numeric simulations were made for a sub-basin located at Cara Preta farm – Santa Rita do Passa Quatro – SP. The aquifer at the local is composed by rocks of Pirambóia Formation, which is part of Guarani Aquifer System. It was developed a conceptual model from previous studies in the area, and from that, simulations were made through the software Visual Modflow®. The conceptual model established previously was considered consistent through the results of simulation.

Sociedades sustentáveis pressupõem o uso de recursos naturais na medida em que o limite de capacidade de suporte dos sistemas naturais não seja ultrapassado. Neste contexto, o uso de indicadores de sustentabilidade se coloca no importante papel de operacionalização do conceito de desenvolvimento sustentável. O método da Pegada Ecológica utiliza a conversão dos fluxos de matéria e energia utilizadas por uma população em áreas biologicamente produtivas para a provisão dos mesmos. No presente estudo, será feita uma aplicação deste método para a cidade de Rio Claro, contabilizando-se os principais itens e serviços consumidos pela população. Pretende-se inferir sobre a sustentabilidade na cidade, através da comparação entre a área apropriada para obtenção dos recursos consumidos e o próprio limite da área do município

In this work, it was studied the thermal and fluid dynamic behavior from theorical and experimental point of view of a blast furnace tuyere. The tuyere is responsible for the hot air insuflation into the blast furnace. The parameter used in the comparison was the difference between the cooling water inlet and outlet temperatures. There were used forced convection correlations inside circular sections with adequations for non circular sections. Based on operations dates of flux and thermal loads it was possible to model numerically the tuyere, and, since it was obtained the wall temperatures, estimate the conduction and convection resistances and the heat flux through the walls in contact with the water. The total heat fluxes from wall to water were applied to the energy conservation equation where could be estimated the theorical temperature variation. Compared to the real value, the theorical value presented a difference of 0,2 °C. Considering that the boundary conditions around the tuyere are transitories and that your channels have some rugosity irregularities we can consider the estimation method for cooling system coherent with the real operational parameters

Environrnental issues are in focus lately, mainly due to climate change that have been registered in recent decades. Some of these changes are attributed to the increased atmospheric concentration of greenhouse gases induce, main1y due to anthropogenic emissions. These gases act by absorbing heat in the form of electromagnetic radiation emitted by the planet, and after a time interval, reissuing such radiation in various directions, including back to the surface, causing overheating of the same. Projections indicate that climate change wiIl tend to increase even more. Because of this, in recent years a number of studies are being conducted on the dynamics of inducers of greenhouse gases, especially C02, because that is primarily responsible for the development of that phenomenon. To better understand the flow of C02 are studied specific areas, as regions bordering the forests, soils that are under preparation for agriculture, urban areas, among others. Forests are an important sink for C02, because during the process of photosynthesis, this molecule is captured and used to obtain glucose. Thus, studies of the regions bordering the forests contribute enough to the understanding of the dynamics of C02. Because it requires a large amount of factors, the concentration of CO2 in a given location is very variable and this makes it much more difficult to understand their dynamics and, consequently, the action of the enhanced greenhouse effect. Being a relatively new area of study, there are many controversies about the consequences of the greenhouse effect, so that the community does not believe that climate change resulting from human action. According to them, such changes are merely natural phenomena and periodicals

The process of urbanization that happened in Brazil during the twentieth century led to processes of structuring and re-organization of space, besides the emergence of many urban problems. Industrialization and urbanization are some of the main causes that could be cited as consequences of this process. As a result of the steep rise of cities, the transport systems became fundamental in boosting flows (immaterial) and the mobility of people and stuff (materials) in the territory. The urban model created for the city of São Paulo in the 1930s was repeated over the years in the medium-sized cities, being repeated the same problems that occurred in the metropolis. In this context our work fits in analyzing the changes occurring in the urban area of São José do Rio Preto - SP, from his relationship with the public transportation system in the face of intra-urban spatial configuration of the city. Transport, while it is recognized by authors as being really important for the analysis and intra-urban spatial configuration, has been little analyzed as the object of study by a geographer, and so, our work has more value
