Abstract: A modular dome-like structure comprises a semispheric wall. A lowermost course of the semispheric wall is constructed using a plurality of springers. An intermediate course of the semispheric wall is constructed using a plurality of a first voussoir type. A second to uppermost course of the semispheric wall is constructed using a plurality of a second voussoir type. An uppermost course and third to uppermost of the semispheric wall is constructed using a plurality of a third voussoir type. The modular dome-like structure may have a cap constructed using a plurality of fourth voussoir type and a keystone or the modular dome-like structure may have an oculus. The modular dome-like structure may further include a lateral opening in the semispheric wall. The lowermost course and the intermediate course may be laid in a stretcher bond.

Abstract: Novel phosphotriesterase enzyme (PTE) monomers linked via an amino acid polypeptide are provided, expressed as a singular polypeptide with both subunits of the dimer attached from about 10 to 35 amino acids in length. This novel PTE enzyme has greater stability and/or enhanced activity in comparison to native forms of the enzyme. The novel PTE enzyme act as improved prophylactic medical counter measures against chemical nerve agents, as well as for use as decontaminants, bioscavengers for disposition in animal feedstocks, and components in assay kits.

Abstract: Kits and methods are provided for revealing a hidden element of an article. The article has printing thereon using a combination of visible ink materials and colorless ink materials. An activating solution is applied to a body part using an applicator. The body part is then contacted with the article. The activating solution causes the colorless ink materials to become visible thereby revealing a portion of the hidden element. The portion of the hidden element is revealed in a shape corresponding to the body part.

Abstract: A thermally transferable electrically conductive ribbon includes a carrier web having first and second sides and an electrically conductive layer disposed on the first side of the carrier web. A portion of the electrically conductive layer is transferable to an associated object to form an electrically conductive circuit thereon. A method for making and using the ribbon are also disclosed.

Abstract: In an electrode combination for a radiation head for the generation of electromagnetic radiation comprising an anode means having a tip end component and a cathode means, the tip end component comprising a material able to facilitate, in response to a predetermined pulse voltage applied between the anode means and cathode means, the generation of electromagnetic radiation, the improvement wherein the electrode combination comprises a trigger electrode, the tip end component, the cathode means and the trigger electrode being spaced apart from each other by a respective predetermined distance.
