Measurement of Condensed Water Content in Liquid and Ice Clouds Using an Airborne Counterflow Virtual Impactor

Creator:: Twohy, Cynthia, Schanot, Allen J., and Cooper, William A.
Abstract:: Condensed water content (CWC) measured using a counterflow virtual impactor (CVI) with a Lyman-α hygrometer downstream is compared with that measured by other airborne instruments (a hot-wire probe, a PMS FSSP, and a PMS 2D-C). Results indicate that the CVI system provides a reliable measurement of CWC in both liquid-...

Isolation and determination of the free fatty acids of milk fats

Creator:: Khatri, Lakho Lilaram
Abstract:: The free fatty acids of milk fat are believed to be involved in imparting flavor properties to milk and other dairy products. In the past the free fatty acids have largely been related to quality deterioration and hence the methods for measurement have been devised to determine the changes in...

Optical and EPR investigations of the photochemistry of KCl:OH

Creator:: Bowen, Robert Clifford
Abstract:: The hydroxide ion as a substitutional defect in KC1 can be photo-dissociated at liquid nitrogen temperature by ultraviolet light. The photochemistry of this system was investigated by EPR and optical absorption methods. Theoretical calculations were also performed in an investigation of the KC1:OH system. The bleaching behavior of photochemically colored...

Abstract:: Upper Klamath Lake in south central Oregon annually experiences intense blooms of cyanobacteria, primarily Aphanizomenon flos-aquae. Domination of the lake phytoplankton community by this single species regularly results in drastic changes to water quality. Photosynthetic activity of such extensive populations can result in pH over 10. Blooms typically expire in...
