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)

The potential of an intact rye cover crop to reduce machine-induced compaction was the subject of this study. A randomized complete block field experiment was conducted in southwest Virginia in a fine, mixed, mesic, Aquic Agriudolls and in a fine-loa

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

A mobile fan testing unit was developed for in situ measurement of total airflow delivered by agricultural fans. A supply fan driven by a diesel engine through a hydrostatic drive was used to deliver air through a perforated plate into a canvas duct

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

The bimolecular rate constant for solvent displacement, k(2), from [(C(6)H(6))Cr(CO)(2)Solv] by an incoming ligand has been determined in the room temperature ionic liquid, [bmim][PF(6)], and is compared to that for the same process in cyclohexane an

The water quality benefits of reduced tillage practices have been compared extensively for corn and soybean production systems. Less research has been completed, however, that examines water quality benefits of reduced tillage in tobacco production s
