This paper presents the development and the main results for an interleaved boost rectifier operating as a special input power stage for a trolleybus type vehicle, allowing its feeding by alternate current (AC) or direct current (DC) distribution power systems. When feeding with two wires (single phase) alternate current distribution system, the converter accomplish active power factor correction, providing a relatively sinusoidal current with low total harmonic distortion (THD) and fully complying with IEC 61000-3-4 standards. In addition, a management control system promotes the required automatic operation changes for the proposed rectifier when the vehicle is changing from the DC distribution power system to the AC distribution power system and vice-versa, keeping its original electrical DC system characteristics for the adjustable speed driver sub-system. The main experimental results for a prototype rated at 150kW are presented, considering its application for a trolleybus with DC adjustable speed driver, demonstrating the proposed converter benefits and the possibility of AC feeding system for trolleybus type vehicle.

The current paper had as its objective to analyze the precision planter's operational performance according to five different displacement velocities and two types of jumpers for planting no-tillage corn. The utilized experimental delineation consisted of blocks at random with parcels subdivided in factorial scheme 2x5, two types of jumpers (4 and 5 staples) and five different displacement velocities (3.0; 4.5; 5.0; 7.0 e 9.0 km h-1) with four repetitions and by applying the average comparation test, as for the jumpers effects as for the displacement velocities effects, to the significance level of 5%. It was evaluated the data concerned to the longitudinal distribution of plants, average number of days for the emergence of seedlings, initial and final stand of plants, survival indices, mechanical harm on seeds, germination tests and grain production. It was also observed the planter displacement velocity effect of on variables as: longitudinal distribution of plants, average number of days for the emergence of seedlings, initial and final stand of plants, mechanical harm and yield. The survival indice of plants were high for all the studied velocities and jumpers. Among the studied velocities, the one of 5.0 km h-1 presented the highest yield to both types of jumpers.

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.

The present study conducted an analysis on policies for early children education in the city of Sao Paulo, establishing a comparison between the callled Direct Early Children Education Centers and the Contracted ones. Within this comparison, we find data extremely different on the two ways of managment listed above, regarding hours of teacher training, their rights and gains, the worked hours and amount of professionals involved in each of them. The results demonstrate that, although there are the same responsabilities in both situations, the rights concerning them are completely distinct
