Abstract: A device positions an ultrasound transducer for ultrasound therapy to focus a treatment beam emitted by the ultrasound transducer at tissue of interest. The device includes at least three anchors which support the ultrasound transducer. The device further includes at least three extendable structures, each with a coupling that supports a corresponding one of the at least three anchors. A drive mechanism of the device independently drives each of the at least three extendable structures towards or away from a subject to move the ultrasound transducer within at least three degrees of freedom.

Abstract: A device (16) positions an ultrasound transducer (14) for ultrasound therapy to focus a treatment beam (12) emitted by the ultrasound transducer (14) at tissue of interest. The device (16) includes at least three anchors (20) which support the ultrasound transducer (14). The device (16) further includes at least three extendable structures (24), each with a coupling (22) that supports a corresponding one of the at least three anchors (20). A drive mechanism (100) of the device (16) independently drives each of the at least three extendable structures (24) towards or away from a subject to move the ultrasound transducer (14) within at least three degrees of freedom.

Abstract: A magnetic resonance position and orientation marking system includes fiducial assembly (30) with at least three fiducial markers (31, 32, 33) each coupled with at least one magnetic resonance receive coil (70, 74, 80, 84). At least one of the fiducial markers has at least one of: (i) marker nuclei selectively excitable over 1H fat and water resonance, 5 and (ii) a plurality of magnetic resonance receive coils (70, 84) coupled therewith. At least two magnetic resonance receive channels (40, 42) receive magnetic resonance signals from the at least three fiducial markers (31, 32, 33) responsive to excitation of magnetic resonance in said at least three fiducial markers by a magnetic resonance imaging scanner (10).

Abstract: Disclosed is a method for the preparation of norbornene and substituted norbornene compounds via a Diels-Alder reaction, in which a cyclic diene is reacted with an olefinic compound in order to prepare a norbornene compound. According to the invention a cyclic diene is gradually added to react with an olefinic compound, in order to keep the concentration of the cyclic diene in the reaction mixture as low as possible during the reaction. It is possible to obtain a very pure product, high yield, short reaction time and high concentrations of the exo diastereomer with the method of the invention.

Abstract: A heat transfer/cooling fluid for low temperatures containing from about 15% to about 70% of trimethyl glycine or derivatives thereof and from about 30% to about 85% of water. The heat transfer/cooling fluid is environmental-friendly and non-toxic. It has good heat transfer properties and is suitable for, e.g., the needs of the food industry and solar panels.

Abstract: The invention relates to a procedure for determining a quantity dependent on the rate of diffusion in the fibre wall for diffusion occurring through it, in which procedure a diffusible tracer is introduced into the fibres under measurement, the fibres are suspended in an aqueous phase and the tracer concentration is determined after a certain time has elapsed since the time of suspension of the fibres, and the quantity dependent on the rate of diffusion is calculated on the basis of the concentration and time.

Abstract: A payout gate for a gaming device, which comprises a gaming panel supporting several payout gates, each gate comprising two pins fastened to a bearer, which pins form between themselves for a coin moving along the gaming panel an inlet into a sensor operating a machinery for distributing payouts, and a tightening means fastening the bearer to the gaming panel, in order to fasten the pins to the gaming pane with a constant tightness, the tightening means comprises a tightening part to be fastened firmly in a constant position with respect to the gaming panel and a spring means situated between the tightening part and the bearer and pressing the bearer axially flexibly against the gaming panel.
