Herein is described Nanostructure Enhanced X-ray Therapy (NEXT), which uses nanomaterials as radiosensitizers to enhance electromagnetic radiation absorption in specific cells or tissues. The nanomaterial radiosensitizers emit Auger electrons and generate radicals in response to electromagnetic radiation, which can cause localized damage to DNA or other cellular structures such as membranes. The nanomaterial radiosensitizers contain moieties for specific targeting to molecules or structures in a cell or tissue, and can be functionalized for increased stability and solubility. The nanomaterial radiosensitizers can also be used as detection agents to help in early diagnosis of disease. Together with known techniques such as Computed Tomography or Computerized Axial Tomography (CT or CAT scan), these nanomaterial radiosensitizers could allow early diagnosis and treatment of diseases such as cancer and HIV.

A textile drying machine comprises a tank for receiving textiles with a spindle inside the tank for supporting the textiles, and a solid-state radio frequency generator. The generator is connected to the spindle and the tank is earthed so that when the generator is operated an oscillating electric field is generated between the spindle and the tank, and hence applied to textiles on the spindle. The electric field heats water molecules in the textiles by molecular vibration so that evaporation occurs, and the water vapor is removed from the tank by an extractor fan. The machine may also be used to dye the textiles prior to drying, thus providing an integrated dyeing/drying machine.

A method for forming tear lines in the rear side of an automobile interior article having a cover portion being developed from which an airbag inflates. When either an automobile interior article body having an integrally molded surface portion or an automobile interior article surface portion is to be molded, the mold is opened after tear line forming projections are moved forward and backward with the mold closed. Thus, the tear lines can be formed at the molding time without any visible extrusion marks of the tear line forming projections on the front surface side (the design face).
