Thermal expansion and cracking of the ceramic potting in dispenser cathodes can lead to failed cathodes. Finding alternative potting materials or optimizing current potting materials with additives may be an avenue to improve the quality of dispenser cathodes. This paper is the result of an undergraduate student project performed by the University of Kentucky with the sponsorship of Semicon Associates...
Brevibacterium linens has commercial significance in the dairy industry and potential application in the production of bacteriocins and carotenoids. Strain development of these industrially significant organisms would be facilitated by the use of vectors, yet few are available. In this study we report the isolation of four novel plasmids from the Gram-positive coryneform B. linens, and determine the...
The spatial variability of turbulent flow statistics in the roughness sublayer (RSL) of a uniform even-aged 14 m (= h) tall loblolly pine forest was investigated experimentally. Using seven existing walkup towers at this stand, high frequency velocity, temperature, water vapour and carbon dioxide concentrations were measured at 15.5 m above the ground surface from October 6 to 10 in 1997. These seven...
