1 Introduction Mercury (Hg) is a naturally occurring element that is commonly found in the environment During the post-industrial era combustion of fossil fuels combined with long-range atmospheric transport has increased the Hg in soils and sediments by a factor of 3 to 10 times () and the global Hg emission into the atmosphere was reported to amount to 3000 t in 2005 (Branch 2008) COMPASS for Pressure Calibration Software features Designed specifically for pressure calibration applications Runs complete automated calibration sequences on single or multiple devices under test (DUTs) including leak testing and pretest exercising Can

Wine grapes grow almost exclusively between thirty and fifty degrees north or south of the equator The world's most southerly vineyards are in the South Island of New Zealand near the 45 th parallel and the most northerly is in Sweden just above the 59 th parallel As a rule grape vines prefer a relatively long growing season of 100 days or more with warm daytime temperatures (not above 95

Yeast cells can exist in both a haploid and diploid state (a) Diploid cells are heterozygous for the mating type locus (mating type a/α) which makes diploids incapable of mating Haploid cells have either mating type a or mating type α making them capable of mating with a cell of the opposite mating type In nutrient-rich conditions both
