Investimentos em transporte intermodal no Brasil poderia beneficiar o crescimento do PIB

[PT] Brasil é um dos países em desenvolvimento que faz parte dos BRICS, os quais juntos têm um potencial de crescimento e consumo de mais de 50% do PIB global. A distribuição de bens produzidos no território brasileiro requer um gerenciamento complexo devido a suas dimensões continentais. Uma rede de transporte mais eficiente e integrado deve reduzir os preços e trazer competitividade aos produtos brasileiros. A solução não é única e requer um planejamento global dos transportes, incluindo o uso de vários meios, transportes intermodais, o que reduzirá custos e tempo de entrega. Optou-se por um estudo qualitativo de banco de dados de agências governamentais e análise de estudos publicados sobre o tema. Este estudo apresenta os dados de custos baseado em preços internacionais. O Brasil tem adotado, tradicionalmente, o transporte rodoviário, apesar de ter outras opções disponíveis, como ferrovias ou hidrovias. Os resultados indicam que se o país não faz os investimentos necessários em modais adequados, perderá competitividade internacional levando à diminuição do PIB. Estudos de simulação de investimentos em modos de transporte e suas implicações sobre o crescimento do PIB seria o curso natural deste estudo. A importância deste trabalho é apontar para a necessidade urgente de investigar e investir outros meios de transporte nos países em desenvolvimento[EN] Brazil is one of developing countries part of the BRICS, which together have the potential to increase production and consumption by more than 50% of global GDP. The distribution of food produced in Brazilian territory requires a complex assessment, due to its continental dimensions. A network of more efficient and integrated transportation should reduce prices and bring competitiveness to Brazilian products. The solution is not unique and requires a global transportation planning, including using various means, intermodal transportation, to reduce costs and delivery time. This study aimed to analyze alternative modals other than roads, to deliver products within Brazilian territory. A database qualitative study was selected using governmental agencies data and analysis of published studies on the topic. Simulation was done to bring the decision-making using officials data projection. Using data from the literature review of government data on the subject, and further application in transport, simulation was applied seeking other alternatives for roads. Results presented national options and their costs based on international prices. Brazil has traditionally adopted road transportation, and other options are available, as railways or waterways. Results also indicate that if the country does not make the necessary investments in adequate modals, it will lose international competitiveness leading to decrease in the GDP. Include simulation studies on investments in modes of transport and its implications on GDP growth would be the natural course of this study. The importance of this study is to point out the urgent need to investigate and invest other means of transport in developing countriesThe authors wish to thank CAPES and CNPQ, and the Universitat Politècnica de València (UPV).Garcia, S.; Vicens Salort, E.; Nääs, I.

Ventilação natural e temperatura da superfície de pisos aquecidos em escamoteadores

This research had the objective of evaluating the influence of the natural ventilation on the surface temperature distribution of heated crates. The research used six crates from a farrowing room in a commercial swine production farm located in the state of São Paulo, Brazil. Three crates were heated using a heat mat while the other three had the environment heated by incandescent light bulbs (200W) fixed on the lateral wall. The surface temperature of the crate's floor (1.55x0.55m) was registered in 36 points, distributed in 18 quadrants (0.26x0.18m) using an infrared thermometer in three different conditions of the room's natural ventilation: opened, semi-opened, and closed lateral curtain. The isotherms and the temperature distribution of the floor heat were processed using the SURFER® (1995), and the statistical analysis was done using the MINITAB® (Statistical..., 2002). It was found that the room's natural ventilation had a significant influence on crate floor surface temperature distribution. The crate with a heat mat system provided higher temperatures and led to a more homogeneous surface temperature distribution.O objetivo deste trabalho foi avaliar a influência da ventilação natural sobre a distribuição da temperatura na superfície de pisos aquecidos em escamoteadores. Foram avaliados seis escamoteadores da maternidade de uma granja de suínos localizada no estado de São Paulo. Dentre os escamoteadores avaliados, três deles usavam piso aquecido para o acondicionamento dos leitões, e os outros usavam lâmpadas incandescentes (200W), fixadas na parede lateral do interior do escamoteador. A temperatura da superfície do piso (1,55x0,55m) foi registrada medindo-se 36 pontos distribuídos em 18 quadrantes (0,26x0,18m), por meio de um termômetro infravermelho, em três diferentes condições de ventilação natural: com cortina lateral aberta, semiaberta e totalmente fechada. As isotermas e a distribuição da temperatura sobre o piso aquecido foram processadas usando-se o software SURFER®. Verificou-se que a ventilação natural teve efeito sobre a distribuição da temperatura da superfície do piso dos escamoteadores. O escamoteador aquecido com manta térmica forneceu temperaturas mais altas e distribuição mais homogênea na superfície de contato com os leitões.47748

Estimulação Térmica Dos Embriões Da Linhagem Ross® Em Escala Comercial

Artificial incubation is an essential process to obtain healthy birds with good performance; nevertheless, it requires sustained improvement. During this process, incubation temperature is considered a critical factor, which has been studied. The objective of this study was to evaluate the development of Ross® embryos after hot and cold thermal stimulation. To this end, temperatures 1.39ºC above the standard temperature and a temperature fixed at 36.00ºC that varied 1.00 to 0.30ºC below the standard temperature were applied during the final embryonic development period (days 14 to 18) for three hours, on a commercial scale. Results revealed that hot and cold thermal stimulations did not cause embryo mortality; the hatching and chick quality index were maintained and even increased. Therefore, we believe that thermal stimulation has the potential to improve hatchery index, and thus grange performance; however, adjustments are needed, varying according to each individual hatchery, before it can used as a protocol. © 2016, Universidade Federal de Santa Maria.
