Compositions and methods useful for providing one or more benefits, including a color rejuvenation andor color maintenance benefit to a fabric are disclosed. The method includes providing a pulsed laser source for generating a pulsed laser radiation and focusing optics; and focusing a pulsed laser radiation to a focal zone within the liquid, with energy exceeding the threshold of optical breakdown in the liquid at the focal zone. The present inventors have discovered that the nature and relative concentration of the polyarylene sulfides, mineral fillers, andor other materials in the thermoplastic composition can be selectively tailored so that the resulting resinous component has a coefficient of linear thermal expansion andor color that is similar to the metal component. The subject devices include at least one site flow characterization element for determining the flow characteristics of a potential physiological sampling site andor at least one sample type characterization element for determining whether the vasculature is arterial, venous or neither, i. The result is a vibration stimulus delivery device that delivers a more robust and intense vibration stimulus to the animal. The invention also concerns a method for the production of a mineral wool product using the said binder for binding the fibers.
