Abstract: A method is provided for synthesizing PLA/apatite composites with improved mechanical strength. In one aspect, a calcium-phosphate/phosphonate hybrid shell is developed to incorporate more reactive hydroxyl groups onto hydroxyapatite (HA) particles. PLA is covalently bonded to HA calcium phosphate hybrid shell, creating a strong interphase between HA and PLA, thus significantly improve the mechanical strength in comparison to that of non-modified HA.

Abstract: An airport lighting system includes one or more lighting elements, a transient protection apparatus, and one or more electrical control cabinets. The transient protection apparatus is coupled to the one or more lighting elements. One or more electrical control cabinets are coupled to the transient protection apparatus. Each of the control cabinets produces one or more of control and power signals that are effective to operate the one or more lighting elements. The transient protection apparatus is configured to provide protection for one or more of the electrical control cabinets and the one or more lighting elements from electrical surges.
Abstract: A redundant and diverse secondary control system mirrors a primary control system but has some fundamental structural difference as compared to the primary control system to prevent a spread of a security breach from the primary control system to the secondary control system. The secondary control system may operate on different hardware built on different software written with different programming language as compared to the primary control system while performing the same function as that of the primary system. By hardware coding the algorithm to produce actuation signals, software based viruses and worms cannot interfere with the secondary control system's operation. A monitor device receives actuation signals from both the primary and secondary controls signals to determine whether an error occurred and to provide correct actuation signals to the controlled system.
Abstract: Methods and compositions are provided for preventing and/or treating infection by disrupting interactions at or near the surface of mannosylated pathogens or other pathogens exhibiting carbohydrate-carbohydrate self-interaction, thus enhancing the immune system's ability to recognize and destroy such pathogens. In some forms, carrier molecules are provided to delivering polymers or other molecules capable of disrupting intra-cellular interaction and/or self-interaction of surface markers on cells.
Abstract: In some embodiments, phonon based temperature measuring apparatuses include a light source positioned to direct a light toward a prism-resonant cavity interface of an optical resonant cavity inducing an evanescent wave that is guided into the resonant cavity having surface phonon polariton properties; a detector positioned proximate the resonant cavity and configured to detect reflected light from the prism-resonant cavity interface; and a temperature calculator coupled with the detector and configured to determine evanescent light coupling to one or more phonon polariton modes from the resonant cavity, calculate a quality factor as a function of a frequency spectrum of at least one of the one or more phonon polariton modes, and determine a temperature of a dielectric material within the resonant cavity as a function of the quality factor.
