Abstract: Described are matrix liquid crystal displays having two plane parallel support plates which together with a frame form a cell, integrated non-linear elements for switching individual picture elements on the support plates and a nematic liquid crystal mixture which is present in the cell and has a positive dielectric anisotropy and high resistivity. The liquid crystal mixture has a nematic phase range of at least 60° C., a maximum viscosity at 20° C. of 30 mPa·s and a mean dielectricity constant ??8. The liquid crystal mixture contains: a) at least 10% by weight of a liquid-crystalline component B having one or more compounds of the following formulae: and b) up to 90% by weight of a liquid-crystalline component A having one or more compounds with a dielectric anisotropy of ?1.5 to 1.

Abstract: An internal combustion engine of a motor vehicle has an adsorption catalyst which may be loaded with nitrogen oxides and unloaded. During the unloading, the exhaust-gas stream through the adsorption catalyst may be decreased by a control unit or an add-on device, using a valve. During the unloading, a fuel/air mixture may be added to the exhaust-gas stream reaching the adsorption catalyst, by the control unit or the add-on device, using an atomizer. Upon switching over from the unloading to the loading of the adsorption catalyst, the addition of the fuel/air mixture to the exhaust-gas stream is initially stopped by the control unit or the add-on device. The decreasing of the exhaust-gas stream is then ended after a predefined flushing time.

Abstract: The invention relates to therapies for treating cancer patients by targeting the osteopontin isoforms OPN-b and OPN-c. Osteopontin is a cytokine that is essential for cellular immunity, particularly through its full length form, OPN-a. OPN-b and OPN-c are splice variants that lack exons 5 and 4, respectively, of the protein's six translated exons. The invention provides methods for treating cancer patients with therapeutics that inhibit or degrade the OPN-b or OPN-c isoforms specifically, thereby leaving the innocuous OPN-a form intact and available to perform its normal functions in the cell.
