Measurements of respirable dust concentrations by using various samplers in underground coal mines

, 1986
The specific etiological factors of coal workers' pneumoconiosis have not yet been fully understood. The prevention of this occupational disease depends upon elimination or suppression of airborne dust to which miners are exposed. The Canada Centre for Mineral and Energy Technology's (CANMET) research on respirable dust in underground coal mines ...

Mountain‐top spherules: Criteria to identify natural and synthetic particles

Meteoritics &Planetary Science, EarlyView.
Abstract Natural microspherules are important tracers of geologic and environmental processes in modern and ancient deposits. However, anthropogenic contamination can dilute natural collections by releasing synthetic microspherules into the environment.

Coalition Breakdown and Subsystem Exit

Policy Studies Journal, EarlyView.
ABSTRACT Why actors choose to work together (or not) to advance policy has been the central area of inquiry within the Advocacy Coalition Framework (ACF). Existing research has mainly emphasized the pathway towards coalition formation and evolution, underscoring the stable patterns of allies and opponents observable in policy processes over a decade or

Bed‐scale quantitative discrimination of hyperpycnites from intrabasinal turbidites—Results from a channelised slope system in the Upper Carboniferous Westward Ho! Formation, United Kingdom

Sedimentology, EarlyView.
ABSTRACT Features considered indicative of hyperpycnites and intrabasinal turbidites overlap. Outcrop study presented here suggests that the Westward Ho! Formation forms an 800 m high deepwater‐slope system dominated by hyperpycnites. Taking this unit, and other successions where hyperpycnites have been described, as having been deposited solely from ...
