Abstract: An interchangeable adornment for a fashion article has a base and a first attachment element coupled to the base for detachably attaching the base to arbitrary location on the surface of the fashion article and in an arbitrary rotational orientation relative to the surface without penetrating the surface. A first ornament is coupled to the base and a second ornament is detachably coupled to the first ornament by way of a fastener. The first ornament may be mounted on a stem which projects from the base such that at least a portion of the stem passes through a portion of the first ornament which is located between the base and a retainer which extends radially outwardly from the stem.

Abstract: A system for modulating a fan beam for radiation treatment employs shutters that may move rapidly into and out of different beamlets of a fan beam, the shutters having a systematic weighting so that a limited number of shutters may obtain a far greater number of regularly spaced energy reductions.

Abstract: A headband includes a flexible band, a metal strip mounted on the flexible band, and at least one interchangeable decorative ornament having a magnet. The headband is capable of producing multiple looks because of its ability to temporarily accept interchangeable decorative ornaments through magnetic attraction.

Abstract: A modulator for radiation therapy provides modulation of an area beam to decrease treatment time. Separate channels passing modulated “beamlets” are possible by spacing the channels such that spreading of the beams and multiple angles of treatment eliminate cold spots. The space between the channels allows well-defined channel walls and space for modulator mechanisms.

Abstract: A phantom for heavy ion radiation therapy provides characterization of an ion beam that may enter but not exit from the phantom. The phantom may include multiple materials and multiple spatially dispersed ion detectors to obtain signals that may be fit to known beam curves to accurately characterize the location and other parameters of Bragg peak of a given ion beam within a patient.

Abstract: A composition comprises anhydrous alumino-silicate, diatomaceous earth, and/or other natural pozzolans, white clinker, and white gypsum interground together and in a ratio by weight of 5-20% anhydrous alumino-silicate, diatomaceous earth, and/or other natural pozzolans, 3-7% gypsum, and 73-92% white clinker.

Abstract: A process of manufacturing blended white cement comprises the following steps: (a) providing anhydrous alumino-silicate, diatomaceous earth, and/or other natural pozzolans; (b) providing white clinker; (c) providing gypsum; and (d) combining and grinding the anhydrous alumino-silicate; the white clinker, and the gypsum together to form the blended white cement.
