O objetivo deste trabalho é evidenciar a existência de relações entre progresso técnico e desenvolvimento econômico no processo de formação da economia brasileira. Em seu aspecto mais específico, refere-se ao estudo do desenvolvimento da eletrificação e seus efeitos sobre o crescimento industrial no Estado de São Paulo, no período compreendido entre as duas décadas finais do século passado até a década de 1930. Durante este período - quando a economia e a sociedade brasileiras se transformam pelo desenvolvimento de relações de produção de natureza capitalista, ocorridas a partir do fim do escravismo, da introdução do trabalho assalariado, da expansão cafeeira, do aparecimento da ferrovia e dos bancos, das primeiras indústrias e, enfim, de atividades voltadas ao desenvolvimento do mercado interno - , o desenvolvimento da eletrificação e, especialmente, o uso de força motriz elétrica na indústria constituíram transformações essenciais. A o provocarem alterações irrevogáveis na base técnica da indústria contribuíram, também, para a alteração do padrão de acumulação.

The sustainable development is the center of many discussions about the environment, economy and society. Environmental issues bring out problems with the fauna and flora, water resources, land use, population growth, residues, basic sanitation, and others. In this sense, the aim of the present work was to develop an environmental diagnostics and propose measures to mitigate the most significant environmental impacts generated by four enterprises in Antonio Crepaldi Industrial District, located at the city of Presidente Prudente/SP. In the study, it was used the methodology proposed by Moreira (2006), and it was done the following activities: monitoring and analyses of the production process, identification of potential environmental aspects and impacts; assessment of the impacts according to its nature, relevance and significance; proposition of measures to mitigate the critical impacts. As a final result, it was obtained an environmental diagnosis about the situation of each of the four companies studied, and it was possible to know the level of criticality of the impacts in each one, and proposing mitigation measures to control or minimizing them, bringing many benefits to the organization

In this study was shown the historical uses of compressed air by humanity, the general scenario of its uses and the most important steps of a project to set up an industrial network of compressed air, from the selection of a suitable compressor to the design of a distribution network, discussing all the possibilities and their characteristics as well as the feasibility of them. A case study was conducted in a food company where was implemented an industrial compressed air network. Information was collected regarding the consumers points of compressed air, as well as the layout of the new facility, necessary for the development of the distribution system. Two methods were used, analytical and nomogram, which complemented each other to the definition of appropriated tubing, both financially and physically

With the growth of the demand on electric energy in the last decades, the urban distribution and transmission systems have experienced a bigger necessity to improve on the substations, the automation procedures and techniques on the operation maneuvers of such systems, in a sense that better attends the quality levels, availability, continuity and operational reliability. In this way, the objective of the present paper is to perform a study of protection and control on an electrical industrial system involving the procedures of digitizing and maneuvers automatism utilizing operational techniques and other pertinent information used in a typical high-voltage Industrial Electrical System. Analysis were made on short-circuits to specify the main components of the 138 [kV] substation, in addition, there were used digital MiCOM relays to make the protection of the present elements. With that, a program was developed to allow the user to monitor the condition of circuit-breakers through a supervision screen being able to simulate some kinds of faults, as well as observing the characteristics of each device. This way, the importance of having a fast and reliable system that ensures the equipment’s protection and the industrial process continuity due to faults on the electrical system is noticeable. It’s important to highlight that all this digitizing was mainly favored by the development of digital technology on the last years, mainly on microelectronics, also with the appearance of supervision gadgets allowing the development of complex systems in supervision and electric energy control
