A China e a Globalização: aspectos de uma estratégia nacional

The restructuring of the state productive sector of the central government of China is a phenomenon that has occurred since 1978, and is not yet complete. In a centrally planned economy, China's government introduced a series of economic and social transformations in order to modernize the country's economic structure. The flagship of these reforms was the reintroduction of a market economy, living side by side with a strong state control over key economic variables of the country. In this process, there was a restructuring of ownership of enterprises by means of collectivization, the creation of joint stock companies, establishing joint ventures with foreign companies or privatization. The result of this process was the creation of a set of holding companies that operate in strategic sectors of China's economy such as energy, transport, telecom, capital goods and defense. Within this brief article we will focus on the process of opening up and modernization as the expression of a national project that sought to understand the changes in the international economy and sought to adapt the demographic characteristics of China and productive so you get the best out of globalization.

O transporte coletivo intermunicipal no Estado de São Paulo: as linhas suburbanas

Esse trabalho tem por objetivo, mostrar a evolução do sistema de transporte coletivo intermunicipal do Estado de São Paulo. Nesse sentido, partimos do processo de industrialização e nacionalização da indústria automobilística. Procuramos também mostrar a evolução do Departamento de Estradas e Rodagem [DER], no papel de direcionador e gerenciador do sistema. Nesse processo, detalhamos o papel de todos os governos do Estado de São Paulo, na implantação de sistema viário estadual [1950-2006]. Também procuramos demonstrar o surgimento dos principais grupos que monopolizam cada vez mais o setor dos transportes coletivo intermunicipal. Assim, vamos comprovar a tese de que as empresas do transporte coletivo intermunicipal estão utilizando as linhas suburbanas para fazer frente ao grande avanço do transporte clandestino intermunicipal no Estado de São Paulo.

Avaliação econômica de diferentes composições veiculares empregadas no transporte rodoviário de madeira: estudo de caso

Transport is one the essential services for the development of most economic activities. In the forestry sector, the main transport used to carry wood from the forest to local consumption is road. The transport increases the producing costs of wood and may be responsible of a high percentage in the final price of the wood sold in the industry. To reduce the company’s costs and increase the efficiency of forest production those transport activities must be analyzed and improved. In that context, an economic analysis is the main objective of this work, evaluating three different types of log transport from a sawmill in São Paulo´s Southwest region. For this, a data collection was done to compound the costs and the incomes of timber transport, and that way, to do the economic analyses of each transport. The monitoring activities were done in the second 2013 half-year and the research achieved economic viability results utilizing tools and methods of Economic Engineering

Análise da evolução das linhas suburbanas no transporte coletivo intermunicipal do estado de São Paulo

This study aims to analyze the intermunicipal collective transportation in The State of São Paulo, according to the relation of lines per permittee company of June/2002 and June/2012. We worked on the suburban and road bus lines. After analyzing the data, we seek to know how was the evolution of these lines in the State of São Paulo, the regions in which these lines were more developed and the groups that monopolize increasingly the intermunicipal collective transportation. It was made a list of some variables that enabled a comparison with the road system and we also showed the considerable increase of the suburban lines, which became more common as time goes by to compete against the clandestine transportation

Transportador de correia: componentes e cálculos básicos para seu dimensionamento

Increasingly, people searches for an efficient and economic way for transporting bulk materials. Transport through belts is now the most widely used mean for transporting bulk materials, used by companies from various sectors such as mining, quarrying, agribusiness, etc. There are many advantages of using a conveyor belt as compared to rail or by truck. Trucks needs a driver, have a high risk of accidents as well as a high cost for maintenance and as well as trains, after making the downloading of the material, return empty to the next load. The cost for the construction of a railway is very high, making it often impossible. The conveyor belt have a high cost of installation, but it works 24 hours a day, 365 days a year. The upper side of the belt is always loaded, the maintenance cost is average and the risk of accidents is low, causing it to be the ideal way to transport bulk materials. This monography aims to interest the reader about what is a conveyor belt, what are its main components and demonstrate the basic calculations for their sizing and selection of components. Throughout the work, scaled a belt conveyor for use in the mining sector, but the concepts demonstrated apply to the transport of any material

A aglomeração urbana de Piracicaba: uma análise da integração funcional entre os municípios sob a ótica do movimento pendular

The growth area of cities has resulted in a phenomenon of conurbation (or expressing tendency). This correspond to a combine of two or more urban cores, there are formations of conurbations. In this way, there are the formations of urban concentrations and can achieve the step metropolitan or not metropolitan. Besides, this kind of expansion generates many social and environmental problems related about habitation, rubbish, drain, and others. Piracicaba, a city in expansion, recently, shows evidences of conurbation not metropolitan around itself. Like this, the paulista government, at June, 26 of 2012, institutionalized the Urban Concentration of Piracicaba, a regional unity, intending the administration along with 22 cities. However, for this fact, must be taken into account functional integration among urban centers, because the number of municipalities are presented to compose a urban concentration of level not metropolitan. It has checked along this research, according with proposition about 22 cities. Thus, the objective of this research is identify and analyze the functional integration among participating municipalities through the commuting, in other words, the spatial displacement of people, important factor to be taken into account when defining urban concentration. Considering the displacement routine people, the commuting, also aimed identify the flow of public transport intercity travel among the cities of Piracicaba Regional Unity. Then, analyze the criteria used for establish the Piracicaba Regional Unity, if it was considered technical character or if it was prioritized the political character. To conduct this research, it was done the literature review related to the theme and data collection related lines of intercity transportation and often travel with ARTESP and companies responsible for it service

Estudodo sistema eletrico emembarcações maritimascom propulsão diesel-eletrica

The globalization is each day more aggressive and demanding even more that new products be manufactured and therefore be delivered to many places in the globe. Thus, an efficient and vigorous transport system is demanded. There are many ways to transport a product, but one of the most used in the world is shipping. A marine vessel presents diversified structures of size and functions. In order to this system has more efficiency, alternatives should be used to obtain important energy savings. Usually, a vessel present a propulsion system purely mechanical, therefore the use of alternatives propulsions, like diesel-electric, is increasing. This graduation work has as main focus demonstrate the functioning of a diesel-electric propulsion system, since the main characteristics of each component of the system, likewise the analysis and electrical calculation, showing the advantages in relation to the conventional diesel propulsion system

Melhorias dos processos no setor de expedição em uma transportadora de cargas fracionadas

The transport market has forced organizations reduce the cost of services and processes, resulting from the highly competitive and, for such waste at all levels and processes are a focus of study for its elimination. This study refers to carrier fractional loads, located in the municipality of Itapecerica da Serra Layout and headquartered in São Paulo, which requires a rapid development throughout its structure, because its expansion was not accompanied by an evolution of effective processes. The need to increase efficiency in delivery with a reduced cost of transport forced the company to hire a logistics consulting to help identify potential bottlenecks in processes, suggest improvements with greater impact and implementation at the end of a critical analysis of results. This work focuses on the Layout of the warehouse shipping area of this organization and we used the method of action research to the consultant and involved could reach this conclusion collaboratively, as well as interviews with those involved in the process and also visual observation. Tools such as Key Performance Indicator, Mapping Workflow, Analytic Hierarchy Process, Applied Statistics and Standard Operating Procedure were used to assist in the identification, analysis and implementation of the proposed improvements

Simulação do tempo de descarga de caminhões graneleiros em uma estação de transbordo de carga em Porto Murtinho, MS

In the current decade, inter modal transport is widely discussed. In Brazil road transport is used in excess whereas there could be more focus and investment towards water transport. Water transport presents many benefits like being low cost and low maintenance. Sea and river ports today aren't capable of supporting Brazil's transport needs. Therefore, with this obstacle, this paper consists of an attempt of modeling and simulation of the process of unloading grain cargo from trucks, through simulation with ProModel software, to verify the necessity of installing more tumblers at the cargo unloading station in Porto Murtinho, MS

Estudo urbano e ambiental da circulação urbana do bairro de Santo Amaro, cidade de São Paulo

This work is resulted of studies about the urban circulation in the modern cities. It was developed from two case studies: the city of São Paulo, specifically Santo Amaro's neighborhood and the city of Regensburg in Germany. The urban circulation of these places was analyzed starting from the premise that the daily of the inhabitants is a relevant factor to be considered. It was researched the types of transportation, the accessibility, and the clearance of public transportations. One of the main purposes of this work was to present general guidelines for the improvement urban circulation in the modern cities, as well as to supply didactic material that contribute to the reflection about urban circulation focusing priorly on the problems of traffic of driving force vehicles

Requalificação das Praças Monsenhor Sarrion e Nove de Julho e o novo Terminal Urbano de Integração

The Center squares of the middle cities many times don’t have adapted forms to the uses, which change time-to-time, then they turn abased. Through the study case of the Squares Monsenhor Sarrion and Nove de Julho, public squares on Presidente Prudente downtown, where many types of uses occur in the same space with function of organization and reception of several fluxes generated because the centrality caused from downtown. In this context, is necessary re-project the squares, with new purpose of an urban and landscape project, which generates harmonic spaces of passage and permanence, which values the public edifications in the around areas and re-qualified the form of the squares, adapting to the new uses: To organize the public transportation traffic, the urban terminal; to organize the vehicles traffic, the lowering of the Avenue Coronel Marcondes and, mainly, to organize the traffic of pedestrian, the continuity and the physic integration of the squares, through new forms, urban furniture and design to the downtown public spaces

Alternativas sustentáveis para a circulação urbana – estudo de caso: as cidades de Guaratinguetá e Lorena

La circulation urbaine dans les villes brésiliennes a été marquée par l'influence directe de l'automobile. Grâce aux possibilités découlant de l'automobile, les villes se développent de plus en plus désordonnées et exigent la création de nouveaux moyens pour maintenir le flux du trafic. Cependant, la création de nouvelles routes est venu de collaborer avec les embouteillages, parce que plus les routes ont été construites, plus elles ont généré le besoin de transport. La question du développement durable a commencé à être traités de 1987 et alors, les premières idées pour résoudre, entre autres, le problème de la circulation urbaine. Une des solutions suggérées par les études est l'utilisation de transports non-motorisés. Ainsi, le vélo est devenu le grand pari pour un transport plus durable. Au Brésil, le vélo est largement utilisé, mais n'est pas considéré comme un réel moyen de transport, qui conduit à de mauvais investissements et incitations. Par conséquent, des mesures sont nécessaires pour encourager le transport à vélo pour se obtenir, avec d'autres mesures, un transport plus durable. Enfin, l'étude de cas dans deux villes, Guaratinguetá et Lorena, montre l'influence de l'automobile dans la formation de ces deux villes, qui a fini par nuire les autres modes de transport qui auraient pu être mieux utilisés
