Abstract: A methods of treating an infection comprises administering a therapeutically effective amount of a compound described by the Formula (I): wherein: X may be O, S, or NR′ wherein R′ is H or loweralkyl, R1 and R2 may be independently selected from the group consisting of H, loweralkyl, oxyalkyl, alkoxyalkyl, cycloalkyl, aryl, hydroxyalkyl, aminoalkyl, and alkylaminoalkyl; R3 and R4 are each independently selected from the group consisting of H, loweralkyl, halogen, oxyalkyl, oxyaryl, and oxyarylalkyl; R5 is represented by a formula selected from the group consisting of: wherein: X1, X2, and X3 are independently selected from O and S; and R6 and R7 are independently selected from the group consisting of loweralkyl, aryl, alkylaryl, oxyaryl, an ester-containing substituent, and oxyalkyl; or a pharmaceutically acceptable salt thereof.

Abstract: Described is a distance-measuring device and a method for determining a distance, which uses a sensor in the form of a cavity resonator to continuously perform a distance determination and allows diverse possible uses.

Abstract: A method of producing undifferentiated avian cells expressing an embryonic stem cell phenotype. The method includes the steps of collecting avian gonadal cells comprising primordial germ cells from an avian embryo after the formation of the primitive streak; depositing the avian gonadal cells in contact with a preconditioned feeder matrix; and growing the avian gonadal cells on the pre-conditioned feeder matrix in the presence of media for a time sufficient to produce an avian cell culture consisting essentially of undifferentiated avian cells expressing an embryonic stem cell phenotype.

Abstract: A conveyor-belt roller assembly secured inside a conveyor-belt roller and onto an inner shaft, preferably used in conveyor-belts used for carrying high loads of material in hazardous environments. The conveyor-belt roller assembly has a stationary anti-lock shield which protects the rotating exterior surface from coming into contact with the outside elements for example debris and machinery. A dust shield is also position aft of the anti-lock shield to prevent the penetration of small particles and dust into the inner workings of the conveyor-belt roller assembly. The conveyor-belt roller assembly also has deep rings in the load-bearing portion for thermal expansion and contraction as well as heat dissipation. Bridging ribs are positioned across the deep rings to greatly increase the strength and therefore load-baring capacity of the conveyor-belt roller assembly. A tapered labyrinth seal is used so that it can be press locked into position making installation quicker and easier.

Abstract: A optical fiber ribbon midspan splitter tool for quick and easy midspan splitting of an optical fiber ribbon into separate ribbon sub-groups for mass splicing. The device comprises a pair of splitter tool sections each having a base and a lid and defining a slot through the splitter tool. The pair of elongate tool sections are rotatably mounted about a transverse hinge through both sections adjacent one end of the tool. The pair of lids are each mounted to a respective one of a pair of bases so as to open upwardly and outwardly for placement of an optical fiber ribbon in the slot defined within the two adjacent bases of the splitter tool. Magnets are provided at the juncture of the splitter tool sections for maintaining the splitter tool sections in releasable alignment, and a pair of magnets are provided in each splitter tool section at the juncture of the base and the lid for releasably maintaining the base and lid in abutting enclosed relationship.

Abstract: A noise and recoil suppressor that is intended to be mounted within the terminal portion of a firearm barrel. The suppressor is a unitary structure having a cylindrical body and a plurality of chambers extending transversely therethrough and spaced-apart in the longitudinal direction of the device. The chambers are configured so as to restrain and slow the passage of the exhausting gases resulting from a bullet that has discharged and passing therethrough so as to suppress both the resulting noise and recoil from the discharging firearm. The suppressor is provided with external threads adjacent its outer end, and a firearm barrel into which the device is to be slidably inserted is suitably drilled-out and provided with internal threads for threadable securement of the device within the end of a firearm barrel. A second and shorter embodiment of the suppressor is disclosed that primarily functions as a recoil suppressor.
