This work shows the importance of taking a good organization of space for the improvement of urban public transport. The model of urban transport is used improperly aggravating factor that generates diseconomies to society. The reduction of the use of public transport, degradation of environmental conditions, chronic congestion, poor accessibility and high rates of traffic accidents are common in many cities. The case study will be done in Jundiaí - SP, where actions were taken to try to reverse this situation of crisis in urban transport, as the change in transport network system. Will analyze the proposals adopted for the implementation of the new network model, steps taken, questionnaires and results from these studies. Verifying the effectiveness of the new transport network model adopted and its reflection with users, those who use the transportation and / or who directly suffer the influences this

This paper seeks to show which impacts there are of the combined use of different modal for the coffee’s outflow. Nowadays is used, almost exclusively, the roadway to transport. How-ever, for this product with low added value, the types of transports best suited, in the litera-ture, are the railway and waterway. For this, is describe the development and spread of coffee throughout Brazil. Subsequently, is calculate the current cost of transporting two producing regions (Minas Gerais and Rondônia), using for that information about the freight, the social cost, and the level of losses along the way. After that is projected costs if utilizes the multi-modal model, when considering the same cost parameters used for the current model. Here-after, an analysis is made of the obtained cost, speed, consistency, capacity, availability and frequency of each transport model. Therefore, note that the multi-modal system is more ef-ficient and economical than current, based on transport by road

This paper analyzed the energy flow of a route currently designed to transport ethanol from the Midwest region of Brazil for exportation, more precisely from the city of Aparecida do Taboado (MS) to the port of São Sebastiao (SP). The route studied a single modal combined into two pieces, duct - duct. The direct and indirect energy, involved in the operations were used to account for the inputs and outputs of energy from and into the system. The energy input and output were the variables, diesel fuel, lubricants, greases, indirect energy consumption of machinery and equipment, power consumption of labor, the energy consumption and energy consumption in depreciation and maintenance of roads. We found that this route has specific energy consumption of 0,14 MJ km-1 m-3 . The Net Energy Gain (GEl), the Energy Efficiency global (EEg) and Renewable Energy Balance (BEr), which were the energy indicators adopted in this study were obtained respectively: 1.585.958.977,00 MJ; 200,72 and 1.593.900.000,00MJ.

O objetivo deste trabalho foi avaliar o efeito do modelo de carroceria (MC) (metálica dupla ou simples e simples de madeira) sobre a freqüência de diferentes tipos de lesões na carcaça (FLC) e sobre a qualidade da carne dos suínos. Foram utilizadas 360 fêmeas com peso vivo médio de 132,72±11,09kg. Para a análise estatística, considerou-se no modelo os efeitos de bloco (BL), o MC e a interação entre MC x BL. Verificou-se um efeito do MC sobre a freqüência de lesões na carcaça provenientes de briga e a freqüência total de lesões, sobre o pH1 do músculo Semispinalis capitis (SC), sobre o pH U dos músculos SC, Longissimus dorsi (LD) e Semimembranosus (SM) e sobre a cor dos músculos LD e SM. Suínos transportados em carroceria metálica simples apresentaram maiores valores de pH e da cor dos músculos avaliados. Conclui-se que suínos transportados em carroceria simples apresentam maior prevalência de lesões na carcaça e que o transporte dos suínos em carroceria metálica teve efeito positivo sobre os valores de pH e da cor carne.
