1. Railway photography and technology: analysis of the photographic record of Brazilian railway in the 19th century
RESUMO O objetivo deste texto é examinar alguns conjuntos de fotografias de companhias ferroviárias no Brasil, a fim de ressaltar o potencial desse tipo de material iconográfico, não apenas como documentação artística, mas também tecnológica. Tratamos particularmente de uma coleção de 6 mil fotografias reunidas por empresas como Companhia Paulista

2. Aplicação do método de análise de risco ao estudo do descarrilamento. / Aplication of risk analysis method to the derailment study.
This research proposes a risk analysis method applied to derailment event (characterized by the wheel overlap on the rail, which can be caused by many aspects: rail imperfections, rolling stock failures, obstacles etc and which can cause accidents, material and life loss) to increase the safety level on railway transport that actually does not present decrea

3. Grain size evolution of a vanadium microalloyed steel during bar rolling mill - 38MnSiV5. / Estudo da evolução do tamanho de grão na laminação a quente de barras de aço médio carbono microligado ao vanádio - 38MnSiV5.
Microalloyed steels are used as forging stock for many automotive parts such as crankshafts and connecting rods. Using mathematical equations describing the recrystallization kinetics and grain growth, a spreadsheet has been developed to simulate the austenitic grain size evolution during bar rolling mill schedules as a function of temperature, strain rate a

4. Management of reliability in railway rolling stock designs. / Gerenciamento da confiabilidade em projetos de material rodante ferroviário.
É cada vez maior a demanda pela eficiência dos sistemas ferroviários. A confiabilidade do material rodante é um dos fatores de desempenho mais importantes para a eficiência global dos trens de passageiros. Para que índices satisfatórios de confiabilidade, disponibilidade, mantenabilidade e segurança (CDMS) sejam alcançados, deve-se considerar esses

5. Contribuição à análise da capacidade de processamento de trens cargueiros em linhas ferroviárias singelas no Brasil / Contribution to analysis of process capacity of cargo trains on single track railroad line in Brazil
The expessive growth of the railway sector due to the privatization of the operations since 1996, is increasing the participation of this mode in the brazilian transport matrix. However, this growth is obtained mainly from the replacement and increase of the rolling stock and the modernization of the traffic control system, and will soon reach some important

7. Does Ribosomal DNA Get Out of the Micronuclear Chromosome in Paramecium tetraurelia by Means of a Rolling Circle?†
The macronuclear genes coding for rRNA (ribosomal DNA [rDNA]) of Paramecium tetraurelia, stock 51, are arranged in polymers consisting of units made up of a transcribed coding region and a nontranscribed spacer region. The whole macronuclear polymer ends with a portion of the spacer on either end followed by a telomere. Six kinds of macronuclear units, or ge
