    摘要： Aqueous-dispersed polymer compositions are prepared comprising polymerized therein (a) monovinylidene aromatic monomer (e.g., styrene), (b) acyclic conjugated diene monomer (e.g., butadiene), and (c) ethylenically unsaturated carboxylic acid monomer(s) (e.g. acrylic and or fumaric acid) and are further benefited by polymerizing therein (d) a cyanoalkyl ester of an ethylenically unsaturated carboxylic acid. The aqueous-dispersed polymers can also comprise polymerized therein an ethylenically unsaturated nitrile monomer such as acrylonitrile. The use of the cyanoalkyl ester, such as 2-cyanoethylmethacrylate (2-CEMA), results in latex polymers with improved performance in paper coating formulations. In particular, paper coatings can be prepared which have improved performance (i.e., wet and dry pick resistance) in offset printing applications.

    摘要： A pet grooming tool comprises a pet engageable portion formed of polymeric material and having a plurality of teeth. A method of forming a pet grooming tool comprises molding a pet engageable portion out of a first polymeric material and thereafter over-molding a handle portion to the pet engageable portion.

    摘要： In a method and magnetic resonance apparatus for acquisition of image data for a magnetic resonance image, the image data are acquired with an acquisition sequence, in which a k-space matrix corresponding to the image data is scanned in segments with at least two partial acquisitions and in which each of the partial acquisition includes a navigator signal in addition to the measurement signal with which a specific k-space segment is scanned, with which navigator signal a same navigator segment of the k-space matrix is scanned. In one of the partial acquisitions a measure is determined that characterizes the breadth of the distribution of signal values of the navigator signal with regard to the k-space matrix and the partial acquisition is repeated if and when the measure lies outside of a tolerance range.

    摘要： In the operation of a magnetic resonance system, an RF excitation coil emits an excitation pulse such that nuclei in an examination subject are excited to emit of magnetic resonance signals. A number of local coils acquire the magnetic resonance signals emitted from the examination subject, with the magnetic resonance signals acquired by the local coils being coded in frequency space. An evaluation device accepts the magnetic resonance signals acquired by the local coils or accepts intermediate signals derived therefrom via one transmission channel per signal, and corrects the accepted signals using correction signals. The evaluation device uses the corrected signals reconstructing an image of the examination subject. The evaluation device determines the correction signals for all signals to be corrected using the same reference signal.
