The present invention relates to hydrophobic gypsum and to a process for making gypsum hydrophobic, in particular it relates to a powdered hydrophobing additive, a hydrophobic gypsum composition and method for preparing same using granules containing organosilicon compounds as hydrophobing additives. The invention also provides a method for administering at least one systemic acting antifungal agent to an animal which comprises applying an effective amount of the antifungal agent in the form of the drug delivery system of the present invention. The analyte meter includes: a meter housing; a receptacle formed in the meter housing; a processing circuit disposed within the housing; and an input interface within the receptacle and electrically coupled to the processing circuit. A quantitative analysis of subunit b is a means of verifying that the sample is of the intended volume rather than having been reduced in volume due to improper sampling. The breaking waves are introduced into the slits, beach erosion is prevented, and a calm sea area utilized for marine leisure is created.
