摘要:
A process for producing a protein hydrolysate derived from keratin containing material with an oxidative bleaching agent at an acidic pH and mixing the keratin hydrolysate as an additive to the wet-end of a papermaking process. The process achieves a paper with a lower porosity and greater breaking length.

Identification card, comprising a card body (1) with graphic identification information, wherein light emission means emit the identification information in visible or invisible light. The light emission means can consist of a flat light emitting diode (2) (FLED), for instance a Polymer FLED. The FLED can be connected with an internal or external electrical source. One or more layers (8 . . . 13) of the FLED that are needed for light emission can contain the graphic identification information or a part thereof, that is, the graphic identification information can be contained in the shape of that layer or layers and/or in the composition thereof. The graphic identification information can also be contained in the shape and/or intensity of the electrical field in, and the electrical current through, those layers (12), respectively, as effected by the electrical source.

An electromechanical converter, in particular an electric variable transmission, is provided with a primary shaft (5) having a rotor (8) mounted thereon, a secondary shaft (7) having an interrotor (15) mounted thereon, and a stator (10), fixedly mounted to the housing (3) of the electromechanical converter. Viewed from the primary shaft (5) in radial direction, the rotor (8), the interrotor (15) and the stator (10) are arranged concentrically relative to each other. The rotor (8) and the stator (10) are designed with one or more mono- or polyphase, electrically accessible windings. The interrotor (15) forms one whole both mechanically and electromagnetically, and is arranged as a conductor for the magnetic flux in an at least tangential direction.

A method cycle of a method for layerwise production of a tangible object (5) comprises the steps of:—solidifying a predetermined area of a layer (10) of a liquid (3) when said liquid layer (10) is adjoining a construction shape, so as to obtain a solid layer (14) of the tangible object (5);—separating said solid layer from said construction shape; and—moving, relative to one another, the separated solid layer and the construction shape to a predetermined position relative to one another for carrying out a successive such method cycle, so as to obtain a successive such solid layer adhered to the solid layer. For at least one of said method cycles, said solidifying and said separating are carried out such that solidifying of certain parts of the layer (14) takes place simultaneously with separating of other, already solidified parts of the layer.

Matrix for real-time aerosol mass spectrometry of atmospheric aerosols and real-time aerosol MALDI MS method Abstract The invention is directed to a matrix material for MALDI mass spectrometry, to a matrix composition for MALDI mass spectrometry, in particular for aerosol MALDI mass spectrometry, to a MALDI mass spectrometry method, in particular an aerosol MALDI mass spectrometry method, to the use of a specific compound as a MALDI matrix material, and to the use of a MALDI matrix composition in a gas phase coating method. The matrix material of the invention comprises a 2-mercapto-4,5-dialkylthiazole according to formula (I), wherein X is chosen from S, O or N, and wherein R1 and R2 are independently chosen from hydrogen, methyl, methoxy, ethoxy, and propoxy, or wherein R1 and R2 are taken together to form an optionally substituted aromatic ring structure, optionally comprising one or more heteroatoms, or a tautomeric form thereof. A matrix composition preferably includes the matrix material and an alcohol. The alcohol can be halogenated. The MALDI MS method comprises contacting the analyte with the matrix material or the matrix composition; ionising at least part of the analyte, and separating the ionised components using a mass spectrometer, e.g. TOF-MS. Preferably, bioaerosols are contacted with the matrix material in the gas phase.
摘要:
A method of obtaining an image of buried structures in an object, comprising partially irradiating said object by light of a wavelength that images said buried structure; and obtaining a complementary partial image of said buried structure by light diffused from a non-irradiated image area.According to the method, an image can be obtained while discarding specular reflections of the object. Thus, deeper structures will be better visible. In a further aspect, the invention offers a method of enhancing imaging of buried structures in an object, comprising: analysing said image as a first image in order to detect the edges of said buried structure; obtaining a second image by irradiating said object with a second light that visually images said object; and combining said first and second images for defining edges of said buried structure in said visual image.

A method is described for displaying data, wherein the data consists of a number of samples Nr that is much larger than the number of samples Ns that can be displayed on a display. According to the invention sets of Nc=Nr/Ns samples are formed and for each set Nc a single value xt is determined according to a specific algorithm by which important features as reflected by the samples, despite the reduction in samples, still can be displayed with a better SNR than with presently known methods.
