Dendroclimatology along Cliff Environments of Northeastern West Virginia: a Comparison of Ridgetop Pines and Cliff-line Red Cedar

Cliff environments can provide excellent locations for dendrochronological studies. This is largely due to harsh growing conditions that often result in an enhanced sensitivity to climate variability. The relative inacessability of such locations also reduces the chance of anthropogenic disturbance, such as logging and fire. Therefore, depending on the natural stability of a particular cliff en...

Survey of noise in coal preparation plants.

In response to the continuing problem of noise induced hearing loss (NIHL) among mine workers, the National Institute for Occupational Safety and Health (NIOSH) has conducted numerous noise surveys in coal preparation plants. The research, consisting of worker dose monitoring, task observations, and equipment noise profiling, was completed in eight separate preparation plants. Worker dose monit...

Preparation of coal slurry with 2-propanol.

This study explored the feasibility of using waste organic solvents as substitutes for water to prepare coal slurries. The rheological properties of coal-2-propanol slurries were examined and compared with that of coal-water slurry (CWS). The good compatibility between coal particles and 2-propanol resulted in stable particle suspension in slurry which usually exhibit Newtonian behaviour. Howev...
