Despite more than 40 yr of research attributing temporal changes in streambank erosion rates to subaerial processes, little quantitative information is available on the relationships between streambank erodibility (kd) and critical shear stress (τc)

Warm and nutrient-rich wastewater discharged from controlled-environment fish production facilities, such as a recirculating aquaculture system (RAS), is a loss of heat energy and nutrients in addition to being potentially harmful to the environment.

Airflow rates through each plenum port of 71 peanut dryers were measured in situ and ranged from 5 to 15 m3/min/m3. Dryers with one fan, or two fans in tandem, and with four or more plenum ports had lower airflow rates through the two ports closest t

A pneumatically powered, manually directed cutting device for selectively harvesting broccoli has been developed and tested. In 1987 harvest tests, with the device operated on one double or one triple row of broccoli, the harvest rate was not affecte

Despite over forty years of research attributing changes in streambank erosion rates over time to freeze-thaw cycling and soil desiccation, little quantitative information is available on the relationships between streambank erodibility and critical
