Abstract: The synthesis and use of bifunctional molecules to improve the topical and transdermal delivery efficiency of various types of therapeutic agents or agents designed to promote the transdermal delivery of those therapeutic agents either into the skin tissue or into the systemic circulation. Three major classes of molecules are covalently joined as bifunctional substances; chemical vasodilators, passive dermal penetration enhancers and therapeutic or diagnostic drugs. Chemical vasodilators may be delivered into the skin to increasing the blood flow in a tissue that has compromised circulation or they may be used as part of a delivery vehicle to promote the delivery of the drug. Passive dermal penetration enhancers are those chemicals that promote the passive penetration of drugs and other chemicals through the stratum corneum and epidermis of the skin tissue. Drugs and diagnostic agents are the third group of chemicals that are candidates for the linkage of molecules.

Abstract: The disclosed methods and devices incorporate a novel expandable bubble portion which provides superior fidelity to a listener while minimizing listener fatigue. The expandable bubble portion may be expanded through the transmission of low frequency audio signals or the pumping of a gas to the expandable bubble portion. In addition, embodiments of the acoustic device may be adapted to consistently and comfortably fit to any ear, providing for a variable, impedance matching acoustic seal to both the tympanic membrane and the audio transducer, respectively, while isolating the sound-vibration chamber within the driven bubble.  This reduces the effect of gross audio transducer vibration excursions on the tympanic membrane and transmits the audio content in a manner which allows the ear to utilize its full inherent capabilities.

Abstract: There is provided a fatigue test method with which the crack growth can be checked for a plurality of cycle rates in a single test. At a first cycle rate f1 of 0.01 Hz, hydrogen has a greater effect on crack growth than at a second cycle rate f2 of 1 Hz. As a result, an area of large hydrogen effect (an area developed at the cycle rate f1) and an area of small hydrogen effect (an area developed at the cycle rate f2) appear alternately on the fatigue fracture surface, and since these two areas have different fracture surface morphologies, it is possible to see the boundary lines. Consequently, the lengths of the cracks developed under each set of conditions can be specified, and a fatigue crack growth curve can be acquired for each set of conditions.

Abstract: Oscillating angularly rotating a container containing a material may cause the material to be separate. Denser or heavier material may unexpectedly tend to collected relatively close to the axis of rotation, while less dense or light material may tend to collect relatively away from the axis of rotation. Oscillation along an arcuate path provides high lysing efficiency. Alternatively, a micromotor may drive an impeller removably received in a container. Lysing may be implemented in batch mode, flow-through stop or semi-batch mode, or flow-through continuous mode. Lysing particulate material may exceed material to be lysed or lysed material and/or air may be essentially eliminated from a chamber to increase lysing efficiency.

Abstract: The invention relates to a security element having at least one thermochromic colour layer. The thermochromic colour layer is overlaid on a first item of information such that the first item of information is not visible. Only when a first type of heat is input into the thermochromic colour layer does the first item of information become visible. According to the invention, the thermochromic colour layer is not only overlaid on the first item of information, but also on a second item of information. The second item of information is not visible either within a specific temperature range, for example at the usual ambient temperature or at room temperature. Only when another type of heat input, which preferably differs from the first type of heat input, into the thermochromic colour layer is effected, does the second item of information become visible. According to the invention, in the case of the first type of heat input, the colour changes in another geometric distribution or another geometric pattern than in the case of the second type of heat input.
