An apparatus and methods for preventing the accumulation of unwanted materials in an enlarged inner diameter portion of a casing or housing. The method further includes coating the support with a catalyst coating or washcoat, and subsequently exposing the support to a second microwave field, thereby removing water from the catalyst coating or washcoat. The contacts are contained within the housing with their ends extending from the housing on either side. The host transmits a command for settling a state of an application to the first storage system as data, and the first storage system transmits the data to the second storage system. When a first icon is selected while second icon previously selected is being enlarged, the second icon is enlarged to a predetermined size, and then after the enlargement, the enlarged second icon is reduced so as to have a size substantially equal to the size of each of icons which are not selected. In particular, the invention encompasses a compound that acts as a potent antibiotic agent for the treatment of bacterial infections, specifically GI infections caused by toxin producing strains of Clostridium difficile and Clostridium perfringens.
