Transactions in real-time database systems should be scheduled considering both data consistency and timing constraints. Since a database system must operate in the context of available operating system services, an environment for database systems development must provide facilities to support operating system functions and integrate them with database systems for experimentation. With these considerations...
Metered-dose propellant-driven small particle aerosols of a killed whole bacterium,Streptococcus suns, were produced and characterized for their aerodynamic particle sizes and antigenicity as potential respiratory mucosal vaccines against S. suis infections in swine. To facilitate the efficient delivery of such vaccine aerosols to large animals, an electro-mechanical device was developed to synchronize...
Purpose. Develop metered-dose propellant-driven aerosols of proteins using tetrafluoroethane (HFC 134A) as propellant. Methods. Proteins were lyophilized with the propellant-soluble surfactants Triton X-100, Triton X-405, Laureth-9, Brij-30, Nonidet-40, and diethylene glycol monoethylether and then charged with propellants. Results. Small particle aerosols of the experimental protein bovine...
