Abstract: Process credential protection in a virtualized system is described. In-guest process credentials of a guest operating system are registered including binding the process credentials with the following values: a guest address of a first structure that includes subjective credentials, a guest address of a second structure that includes a context in which the process credentials reside, and data fields of the first structure that are not subject to change. A first tag is created from at least the information bound with the process credentials and stored. An integrity verification check is performed at a verification point that is triggered by a function or system call being called by the guest operating system, and includes creating a second tag from at least the information bound with the process credentials and determining if the first tag and second tag match. If they do not match, then the integrity of the in-guest process credentials has been compromised and remedial action is taken.

Abstract: The invention relates to a method and a device (1) for determining a concentration (c) of a fluorescent substance in a medium, wherein an excitation radiation having an excitation wavelength (?ex) is radiated through the medium having the fluorescent substance so that the fluorescent substance is excited in such a way that the fluorescent substance emits a fluorescence radiation having a fluorescence wavelength (?em), wherein the intensity of the fluorescence (Ifluor) is measured, from which the concentration (c) of the fluorescent substance in the medium is determined, wherein additionally the intensity (Itrans,ex) of a transmitted portion of the excitation radiation is measured, wherein the concentration (c) of the fluorescent substance is determined from the intensity of the transmitted portion of the excitation radiation (Itrans,ex) and the intensity of the fluorescence (Ifluor).

Abstract: The invention relates to a device (1) for photometrically or spectrometrically examining a liquid sample (2), comprising a cuvette (3, 3?), which can be arranged in the beam path between a radiation source (4) and a radiation detector (5) and which accommodates the liquid sample (2) to be examined, a radiolucent inlet section (6) for coupling in radiation (20) produced by means of the radiation source (4), which radiation interacts with a sample volume (8), and a radiolucent outlet section (7) for coupling out radiation (20?) intended to be detected in the radiation detector (5), wherein the inlet section (6) has an inlet surface (11) convexly curved in such a way and/or the outlet section (7) has an outlet surface (12, 12?) spherically convexly curved in such a way that the incident radiation (20, 20?) is focused in the manner of a converging lens.

Abstract: A method of producing an electrical component includes forming a stack of ceramic green films, where the stack has a hole that is accessible from external to the stack, inserting a cover into the hole, and sintering the stack together with the cover. The method may also include boring the hole through the stack of ceramic green films.

Abstract: A method of controlling access to an elevator car, in particular to its roof and/or underside, including the steps of switching the elevator control into a maintenance mode which controls the car to travel to a predetermined stop position permitting access, and opening a landing door of the elevator shaft the car is running in. The elevator control is switched into the maintenance mode only if operating a landing call receiving device in a predetermined identification pattern which differs from a call pattern for calling the elevator.

Abstract: Tanned leather is dry dressed by plasma deposition at atmospheric pressure of a matrix material such as ITO, a silicone, or polyurethane, upon the protein fibers of the surface of the leather and the collagen fiber skeleton below the surface protein fibers. The leather retains its toughness, elasticity, breathability and softness or hand.
