1. Flexible pavement with mining waste proposal - execution and analysis of an experimental section
Abstract The extraction of iron ore has a fundamental role in the Brazilian economy. However, such activity generates considerable volumes of waste whose disposal, even if regulated and licensed, has a significant environmental impact. The worldwide concern for sustainable practices along with the urgency for measures to mitigate environmental damage, justif

2. Flexible pavement overlay design of UFJF ring road based on the new Brazilian mechanistic-empirical pavement design method
Abstract The procedures for design and reinforcement projects regarding flexible pavements available in Brazil are mostly based on empirical models developed from studies carried out in specific localities, and therefore, should only be used in cases where equivalent climatic and traffic conditions are observed. The national highway agencies in partnership w

3. A música pop em David Lynch: canções de época em longas-metragens do diretor
Resumo Canções pop e de gêneros adjacentes dos anos 1950 e 1960 são um recurso que o diretor americano David Lynch passou a usar em seus filmes a partir de “Veludo azul” (Blue velvet, 1986) e chegou, de forma esporádica, à temporada de 2017 da série televisiva “Twin Peaks”. O objetivo deste artigo é avaliar se e o quanto tal prática reiterou

4. Emissões de poluentes atmosféricos em condições reais de pavimentação asfáltica: material particulado, black carbon e hidrocarbonetos policíclicos aromáticos
Intensive use of asphalt generates pollutants into the atmosphere which are harmful to the environment and worrying for occupational health. The application of asphalt products leads to emissions of significant concentrations of polycyclic aromatic hydrocarbons (PAHs) and particulate matter (PM) to the atmosphere. This paper aims to assess the pollutant emis

5. Increased power efficiency in mining by using high-fidelity haul truck simulation
Abstract The current economic and political scenario in Brazil has allowed small, medium and large companies to adopt cost cutdown and productivity increase strategies. Diesel fuel consumption by off-highway haul trucks stands for one of the largest costs at the Sossego Mine operational management department. Based on this fact, as well as on the 8% increase

6. The carrion beetle Oxelytrum discicolle (Coleoptera: Silphidae) and the estimative of the minimum post-mortem interval in a forensic case in Brasília, Brazil
Abstract The order Coleoptera is considered second highest in forensic importance in criminal cases involving violent death, because members of this order increase in richness and abundance as the decomposition process progresses. We present here the first Forensic Entomology (FE) case in Brazil where the carrion beetle, Oxelytrum discicolle (Coleoptera: Sil

8. Age and palaeoenvironments of the Manacapuru Formation, Presidente Figueiredo (AM) region, Lochkovian of the Amazonas Basin
Abstract The Manacapuru Formation, Amazonas Basin, outcrops on the margins of a highway in the region of Presidente Figueiredo, state of Amazonas. A systematic palynological and a lithofaciological analysis was carried out aiming to contribute to the paleoenvironmental understanding of the Manacapuru Formation and its respective age. The present work uses th

11. Analysis of a car door subjected to side pole impact
Abstract The results of a study on the response of a side impact beam located in a car door to impact loading is presented. The side impact beam is situated in both the front and rear side doors of a vehicle between the inner and outer shells to minimise intrusion into the passenger compartment during a collision whilst absorbing as much impact energy as pos

12. Seismic evaluation and partial retrofitting of concrete bridge bents with defect details
Abstract The need for seismic retrofitting of bridges after severe earthquakes has become important in recent years. This study examines the seismic evaluation of concrete bents of highway bridges designed and implemented according to the 1990s regulations. Compared with the older codes, 1990s codes have more complex details for connections which are evaluat
