Abstract: A method of manufacturing a preform, the method including positioning at least one glass tube in a glass outer cladding to form a preform precursor, the glass tube comprising a first open end and a second open end, forming a preform from the preform precursor, and thermally treating at least one of the preform precursor and the preform. The thermally treating including sealing the first open end and the second open end of the glass tube to form a closed tube and heating and/or cooling the glass tube to manipulate gas pressure within the closed glass tube.

Abstract: The present disclosure relates to a formulations and methods for transdermal delivery of a medicament through the skin of a subject. In aspects, the formulation comprises a therapeutically effective amount of a medicament and a penetrant portion in which the penetrant portion comprises: a phospholipid, a fatty acid ester formed from a low molecular weight alcohol, and a long-chain fatty acids. In some embodiments, the penetrant portion further comprises one or more of a viscosity-improving agent, a penetration enhancer, and an emulsifier.

Abstract: The invention in one form is directed to a mechanical and electrical coupling assembly for a light fixture, the coupling assembly including a first bracket configured for coupling with an end of a support arm, a first electrical connector mounted to the first bracket, a second bracket mechanically coupled with the first bracket, and a second electrical connector mounted to the second bracket, the second electrical connector being directly electrically coupled with the first electrical connector. The first bracket can be a vertical arm bracket, and the second bracket can be a wireway bracket. Alternatively, the first bracket can be a hanger cap, and the second bracket can be a reflector cap.
