Abstract: A metal-reinforced layered composite includes at least one intermediate metal layer. The intermediate metal layer includes at least two at least partially overlapping metal foils which are joined to one another in an overlap region by at least one weld seam. There are no leakage channels and/or no continuous leakage channels at the weld seam of the metal foils in the longitudinal extent of the overlap region. At least one of the weld seams may have a course which at least at one point has a direction component at right angles to the longitudinal extent of the overlap region of the metal foils. The intermediate metal layer may be provided with at least one passage in the overlap region of the metal foils. A gasket, a gasket sheet, a metal layer and a method of manufacturing a layered composite are also provided.

Abstract: A method of and compositions for suppressing the growth of tumor cells in a patient are disclosed. In one embodiment, the method comprises treating the patient with an effective amount of an isoprenoid ether-linked compound, wherein the isoprenoid ether-linked compound comprises a first acyclic isoprenoid molecule linked via an ether linkage to a second molecule, wherein the second molecule can suppress tumor formation.

Abstract: A flat semi-finished product includes a filled fluoroplastics substrate in the form of a sheet, which is coated at least partially on at least one surface with a soft, thin coating of fluoroplastics. The substrate material of the sheet has a Shore-D hardness of at least 65 and the average layer thickness of the thin sheet coating is at most 20 &mgr;m. A component, in particular a flat gasket, is made from the semi-finished product. A process for the production thereof is also provided.

Abstract: Structures having high height to width ratios may be measured using X-ray techniques, where the surrounding base and the structure are composed of different substances. The technique combines X-ray detection with scanning electron microscope (SEM) beam scanning. The X-ray emission is set to detect the presence of a specific substance which is either in the structure or surrounding the structure.
