Abstract: A process for determining the concentration of pyridostigmine in a sample of biological fluid, comprises mixing the sample with antibody produced from antigen formed from the synthesis of pyridostigmine-p-aminobenzoic acid-bovine serum albumin complex, determining the extent of binding reaction between antibody and pyridostigmine and comparing the measured extent of binding an unknown with known quantitative relationship between binding and concentration of pyridostigmine.

Abstract: Energy conversion among heat or electricity and incandescent light is achieved, in the case of incandescent light emission, with the emission having reduced IR content, using a high bandgap semiconductor element (1) that is tailored in structure and in energy conversion physics to suppress free carrier absorption so as to be transparent or reflecting of photon energy that is below the bandgap of the semiconductor and to only emit photon energy above the bandgap of the semiconductor. A filament of lightly "N" doped 3C-Sic (2), at about 900 degrees C, will incandesce and radiate in the visible range for energies greater than about 2 eV and will exhibit inefficient emission of photons for energies less than about 2 eV.

Abstract: The present invention concerns a method for the production of olefin anhydrides, such as acrylic anhydride and methacrylic anhydride, via reactions between an aromatic acid chloride, such as benzoyl chloride, and carboxylate ions of the olefin acid corresponding to the anhydride to be produced. The method of the invention may be conducted without the use of a solvent, catalyst, polymerization inhibitor, or an external source of heat. Moreover the acrylic anhydrides of the invention can be used to produce high yields of acrylate esters by means of room-temperature reactions, without mineral acid catalysis.
