Abstract: Process for the racemisation of an enantiomerically enriched alpha-amino nitrile characterized in that the enantiomerically enriched alpha-amino nitrile is contacted with a lewis acid catalyst. Preferably an aprotic solvent is used. The lewis acid catalyst preferably comprises a metal chosen from main group elements IA-IVA of the Periodic Table (CAS version), the transition metals and the lanthanides, in particular Al, Ti, Zr, or lanthanides. The catalsyt for example has the general structure MnXpSqLr, and preferably is chosen from the group of aluminum alkoxides, aluminum alkyls, lanthanide alkoxydes and lanthanocenes. The racemisation may be performed in combination with a resolution process, for instance in combination with an enzymatic or a crystallization induced resolution process, preferably in situ, for instance in situ in a crystallization induced asymmetric transformation process.

Abstract: The present invention provides an array of pixels, each pixel comprising: a pixel element, a pixel refresh circuit, a first memory element and a first switch element. Each pixel element comprises a first pixel electrode for individual control of the pixel element and a second pixel electrode, the second pixel electrode linking substantially all pixel elements in the array and being connected to a common counter-electrode. The first and second pixel electrode form a first capacitor. The pixel element has a threshold voltage and a modulation voltage. The pixel refresh circuit is intended for transferring electric charge related to a pixel data value from a data input of the pixel to the first pixel electrode via a charge transfer path. The first memory element is coupled to the pixel data input for storing electric charge related to the pixel data value. The first switch element is located between the first memory element and the first pixel electrode, and is for controlling charge transfer from the first memory element through the charge transfer path to the first pixel electrode. According to the present invention, the first switch element and the first memory element co-operate to transfer charge related to the pixel data value passively along the charge transfer path to the first capacitor. According to the present invention, the array further comprises means for applying a dynamically changing voltage to the common counter-electrode, the dynamically changing voltage changing between a first driving value and a second driving value so that the pixel data value is a signal comprised between zero volts and a data voltage value, the data voltage value being not smaller than the modulation voltage and smaller than the sum of the modulation voltage and the threshold voltage of any of the pixels elements. The present invention also provides a method for refreshing pixel values of an array of pixels.

Abstract: Intracranial abnormal solid cellular masses, particularly tumors or adjacent tissues that may contain tumor cells, are treated by administering to the abnormal area a sufficient amount of a cytotoxic drug comprising a vinca alkaloid dispersed in a stable flowable proteinaceous matrix. The matrix substantially inhibits the migration of the drug from the site of administration, so as to maintain the primary effect of the drug in the region of administration. Migration can be further inhibited by the use of physiologically acceptable materials which modify cellular properties or physiological responses to further regionalize the placement of drug at the injection site.

Abstract: A low differential pressure rotary syphon for the purpose of removing condensate from the interior of a heated dryer drum under low differential pressure conditions. The reduction in the magnitude of differential pressure required to remove the condensate is accomplished through the direct introduction of steam into a central plenum area receiving condensate thereby reducing the mass density of the condensate mixture. The reduction in mass density and the steam introduced acting directly on the condensate within the central plenum area facilitates the removal of the condensate from the drying drum interior. <IMAGE>
