In an ever more competitive environment, power distribution companies must satisfy two conflicting objectives: minimizing investment costs and the satisfaction of reliability targets. The network reconfiguration of a distribution system is a technique that well adapts to this new deregulated environment for it allows improvement of reliability indices only opening and closing switches, without the onus involved in acquiring new equipment. Due to combinatorial explosion problem characteristic, in the solution are employed metaheuristics methods, which converge to optimal or quasi-optimal solutions, but with a high computational effort. As the main objective of this work is to find the best configuration(s) of the distribution system with the best levels of reliability, the objective function used in the metaheuristics is to minimize the LOLC - Loss Of Load Cost, which is associated with both, number and duration of electric power interruptions. Several metaheuristics techniques are tested, and the tabu search has proven to be most appropriate to solve the proposed problem. To characterize computationally the problem of the switches reconfiguring was developed a vector model (with integers) of the representation of the switches, where each normally open switch is associated with a group of normally closed switches. In this model simplifications have been introduced to reduce computational time and restrictions were made to exclude solutions that do not supply energy to any load point of the system. To check violation of the voltage and loading criteria a study of power flow for the ten best solutions is performed. Also for the ten best solutions a reliability evaluation using Monte Carlo sequential simulation is performed, where it is possible to obtain the probability distributions of the indices and thus calculate the risk of paying penalty due to not meeting the goals. Finally, the methodology is applied in a real Brazilian distribution network, and the results are discussed.

Considering the necessity of implementation of the Information Technologies and Communication (ICT) in the public Brazilian schools, the São Paulo State government hearing the call of the federal government and, with the objective to promote the digital inclusion, created the Programa Acessa Escola. The research that we realized and bring expressed on this text, is about such program and allowed us comprehend how it had been developed in the public state schools of the city of Guaratinguetá. By visiting the schools, we saw the manner that each school make use of his informatics laboratory; how they understand the government Project; how they develop actions of use of the laboratory and, particularly, how they use the informatics laboratory to the teaching and learning of mathematics helping the professor and the students. To make possible to understand this use, was realized interviews with the responsible intern of each one of the 14 (fourteen) schools of Guaratinguetá; with the pedagogical coordinator or director of the school and with the mathematics teacher. By the analysis, realized using a qualitative approach of phenomenological nature, we understand that the intern see himself as an auxiliary of the student and professor in the use of the laboratory. The director or pedagogical coordinator understand that the laboratory is an excellent resource to the school, but still exist the necessity of more resources that allow to attend properly the community; and the mathematics teacher consider important the program in the school as much for the students digital inclusion as for the teaching but they feel not safe to use into his classes, because they consider that there is a lack of capacitation and collaboration to make their activities relevant to the learning. That make possible to recognize what is the function of the intern and what is the way that the students and professor ... ( Complete abstract click eletroctronic access below)

Laboratory of Chemical Waste Management programs are being implemented in various universities of the country and the world, in recognition of the urgent need to change the reality of disregard for the environment, together with objective responsibility of the generator, and especially the awareness of sustainability. Analysis and research laboratories involve a range of waste in developing their studies with intrinsic characteristics related to their form of generation. The amount of waste generated in this segment is negligible compared to industrial activities, but the environmental issue is that these residues do not have a standard technique for treatment due to the potential variation of its composition. This research project, aiming their suitability and continuous improvement, aims to diagnose and analyze the current situation of the management and disposal of chemical waste generated by the laboratories IGCE UNESP, Campus Rio Claro / SP. Universities, through their research, teaching and extension, end up generating potentially hazardous chemicals that may contaminate the environment when they are disposed of improperly, with no concern for the environment and / or public health. Aiming to assist in improvements with respect to this issue, the purpose of this study is to understand the management and disposal of chemical waste from the IGCE, laboratories UNESP - Rio Claro / SP, in order to discuss the situation of such waste, and present proposals to reduce generation of the same and minimizing the environmental impact, thereby increasing the local hygiene through proper disposal. The research instrument used interviews, questionnaires, review of recent literature and observations were made in order to develop proposals for the management and disposal of waste. These proposals based on prevention and corrective control, where the preventive approach aims at lifting techniques and actions to reduce the generating sources and...

The Creative Economy is an experimental laboratory for the creation , innovation , invention and reinvention of the universe of media - analog and digital . The scenery in the media and converging technologies favors the process of “ creative destruction and destructive creation “ of this field . The mapping of basins and technological corridors distributed through the territory of concentrated areas creates an infrastructural chassis for the production of content , information and entertainment . As locus and logos of immaterial production , digital ecology that gives speed to the flow of production - planning, fundraising , publishing , distribution and enjoyment - and allows the dispossession of their local clusters , the fragmentation and dilution of their creative chains . The collective cultural production and creation appropriating these capilarizados articles and produce content against political, economic and social status quo . The land is fertile and favorable to the emergence of radical media and rebels that recreate the public sphere , and edit poor public spheres , alternative , radical and efficient , the tactical point of view . This article aims to contribute to studies and research that scour the ecosystem of the media for understanding the management of their creative processes, actors and critics of tangible and intangible resources that support their communication actions .

Com o objetivo de preservar e disseminar o acervo da Universidade de São Paulo, foi criada a Biblioteca de Obras Raras e Especiais. Contamos atualmente com cerca de 2500 obras digitalizadas em parceria com a Brasiliana USP e apoio da FAPESP. Estas obras estão disponibilizadas online, para consulta aberta pelo amplo público, promovendo assim acesso ao conhecimento. Utilizamos para isto o Corisco, uma plataforma desenvolvida por pesquisadores da Brasiliana USP baseada em DSpace, software de código aberto e com recursos que promovem a interoperabilidade com outras bases. O DSpace é atualmente o aplicativo de Repositório Digital de código aberto mais utilizado nas Universidades ao redor do mundo. As capturas originais em alta resolução das obras são armazenadas e indexadas para fins de preservação. Em outra frente, realiza-se o tratamento, compactação e reconhecimento ótico de caracteres nas imagens, para que então as obras possam ser disponibilizadas na internet com o recurso de busca no conteúdo. A consulta é livre e gratuita, garantindo assim, além da preservação, o acesso ao conhecimento pela comunidade acadêmica e público em geral.
