“…In Brazil, bus demand decreased by approximately 40% between October 2020 and February 2021 and rail demand decreased by 55.9% between March and December 2020, when compared to the same period of the previous year [13,14]. Although other travel modes had a drop in demand, in the case of UPT, the reduction in demand was greater [15,16].…”

Travel Behavior before and during the COVID-19 Pandemic in Brazil: Mobility Changes and Transport Policies for a Sustainable Transportation System in the Post-Pandemic Period

This article was motivated by the urban mobility changes observed at the onset of the COVID-19 pandemic in Brazil. We aim to analyze travel behavior before and during the COVID-19 pandemic in Brazil considering two samples of revealed preference online data, independent samples tests, multinomial logit models (MNL), and mixed logit models (ML). The analysis shows a decrease in Urban Public Transport (UPT) use. Comfort and frequency of the UPT service were important factors to attract users during the pandemic period. Ridesourcing services were used for leisure purposes before the pandemic. During the pandemic, they were used for health purposes. Active modes were used more for shopping and leisure purposes during the pandemic. Regarding car users, such as drivers, it was found that they used ridesourcing less often during the pandemic than before. The main contribution of this research concerns the changes in travel behavior that might remain and how these analyses can shape sustainable transportation public policies in the future. Therefore, for a Brazilian study case, this article suggests an increase in the quality of UPT services, a reform on pricing regulations for UPT, an increase in the infrastructure for active modes, an implementation of car demand management strategies, and more strategies to support teleworking as a form of traffic demand management.

“…Red ceramics is one of the main materials used in civil construction, accounting for 4.8 % of the sector. It is used mainly for the production of bricks, tiles and pipes [1,2] . Although the data is outdated, it is estimated that in Brazil the total number of red ceramic factories is 6,903, contemplating industries from small to large [2] .…”

The present study investigated the incorporation of sugarcane bagasse ash (SCBA) in red ceramics, sintered in conventional oven and microwave oven, aiming to provide an alternative product, and a sintering process with higher energy efficiency in the production of red ceramics. The raw materials were characterized by XRF, XRD, thermogravimetry, particle size distribution and specific mass analyses. The specimens were shaped by extrusion in two different compositions, red clay and red clay with addition of 20 % SCBA and sintered at temperatures from 700 to 1100 ºC. The conventional sintering occurred for 60 min with heating rate of 10 ºC/min. In the microwave oven the sintering occurred in a hybrid way, with heating rate of 50 ºC/min for 5, 10 and 15 mins. After sintering the tests of linear shrinkage, compressive strength, water absorption, apparent porosity and apparent specific mass were performed. The addition of SCBA causes an increase in the values of water absorption and decreases the compressive strength and specific mass of the red ceramic. This occurs due to the creation of pores inside the material from the volatilization of organic matter present in the ashes. The sintering in microwave oven, when compared to conventional sintering, promotes an increase in the values of compressive strength and specific mass and reduction of water absorption values of ceramics, probably due to the refinement of the microstructure and the higher densification. Thus the incorporation of ashes can be partially compensated by a more efficient sintering. The use of SCBA and the sintering in microwave oven, showed to be viable alternatives in the development of a more sustainable and light material, promoting the management of waste, reduction in the consumption of raw materials and energy saving.

“…Na década de 90, visando debelar a inflação, ajustes recessivos foram realizados pelo Estado, em meio a uma brusca abertura comercial (BALTAR; DEDECCA; HENRIQUE, 1996). Trabalhadores, empresariado e governo federal firmaram acordos, no âmbito da Câmara Setorial Automotiva, na busca de reverter a queda nas vendas, na produção e no emprego daí resultantes, mas as medidas tomadas foram ao encontro das novas estratégias de globalização, hierarquização e redução da cadeia de fornecimento de autopeças, já em utilização pelas montadoras no plano internacional 30 , entre cujas conseqüências está a concentração de atividades e de capital das empresas no setor de autopeças sob o domínio de poucos, porém poderosos, grupos oligopólicos transnacionais (COSTA; QUEIROZ, 1998;LAPLANE;SARTI, 1995;LAW, 1991).…”

Em primeiro lugar, gostaria de registrar aqui o meu mais profundo reconhecimento pelo trabalho do Professor Ricardo Antunes, pela dedicação, comprometimento, arrojo, genialidade e, sobretudo, generosidade, na condução de suas orientações. Pude desfrutar, na sua companhia e na do grupo de pesquisadores (as) que coordena, vinculado ao CNPq, de uma abastada bagagem teórica, sempre renovada mediante um companheirismo, uma troca de experiências de pesquisa e de vivências, cuja importância para mim sempre será inestimável. Sem dúvida, devo ao Professor Ricardo Antunes e a este grupo quase tudo o que sei e, de certa forma, o que hoje sou.O mesmo posso dizer da querida Unicamp, onde passei dez anos da minha vida, desde a graduação até o doutorado. É por demais difícil listar aqui nomes, sem incorrer em faltas. Mas não quero deixar de registrar a importância que tiveram na minha formação os professores Dr.
