Application of HP in the atmospheric freeze drying unit

Journal of Physics: Conference Series, 2020
Abstract Method of increasing the energy efficiency of atmospheric freeze drying due to the use of a heat pump unit (HPU) in a circuit are considered in this article. The use of HPU in the composition of the drying unit allows to more fully use the heat of superheated steam and the heat of condensation in the process of freeze-drying at ...

Assessment of atmospheric microbial contamination in a mobile dental unit

Indian Journal of Dental Research, 2007
Bioaerosols are important considerations in infection control as well as in occupational health. Bioaerosols may carry potentially hazardous microbes, viruses, fungi, allergens, and other toxic substances that may harm the dental operator, patient, and the dental assistant by causing nosocomial infections.To assess the level of atmospheric microbial ...

Increasing atmospheric burden of ethanol in the United States

Geophysical Research Letters, 2012
The use of ethanol as a transportation fuel in the U.S. increased significantly from 2000–2009, and in 2010 nearly all gasoline contained 10% ethanol. In accordance with this increased use, atmospheric measurements of volatile organic compounds in Los Angeles in 2010 were significantly enriched in ethanol compared to measurements in urban outflow in ...
