Diesel particulate matter (DPM) is a nearly ubiquitous environmental pollutant. It is known to be inflammatory and is linked to a plethora of health effects including asthma, chronic obstructive pulmonary disease, and pulmonary fibrosis. New research sheds light on which components of DPM are harmful to the lung and what mechanisms they trigger [EHP 119(3):332–336; Reynolds et al.]. The authors...

Deformable part models achieve high precision in pedestrian recognition, but all publicly available implementations are too slow for real-time applications. We implemented a deformable part model algorithm fast enough for real-time use by exploiting information about the camera position and orientation. This implementation is both faster and more precise than alternative DPM implementations. Th...

By examining the census tracts and towns that are intersected by Massachusetts' major highway corridors, Diesel and Health along Massachusetts' Highway Corridors ascertains whether these areas contain significantly higher rates of diesel particulate matter (DPM), lung cancer, and asthma. DPM was significantly higher for corridor towns than non-corridor towns. Hot spot analysis revealed statisti...

Regulations on worker exposure to diesel particulate matter (DPM) are becoming increasingly stringent in the mining industry. Due to the complexity and unpredictability of this aerosol, there is a need for new tools to help mines develop an effective strategy to reduce DPM concentrations. To address these needs, NIOSH has developed a portable elemental carbon monitoring device for use in underg...

Abstract Discrete phase method (DPM) model was used to analyse rotary drum systems for segregation behavior. DPM simulations were performed comparison with a dynamic experimental measurement from the literature. This included and time-averaged particle velocity field, which validated data. In addition, direct parcel scaled simulation study effect of size scaling. The dynamics evaluated using La...

Purpose – The purpose of this paper is to investigate how to measure collaborative design performance and, in turn, improve the final design output during a design process, with a clear objective to develop a design performance measurement (DPM) matrix to measure design project team members’ design collaboration performances. Design/methodology/approach – The methodology adopted in this researc...

A theoretical model based on Fulton and Gouterman dimer Hamiltonian [J. Chem. Phys. 35, 1059 (1961)] is used to understand the jet cooled spectra of partly deuterated diphenylmethane (DPM-d5), reported in adjoining paper by Zwier and co-workers ["Vibronic coupling in asymmetric bichromophores: Experimental investigation of diphenylmethane-d5," J. Chem. Phys. 141, 064316 (2014)]. The model is ex...
