Aufbau und Arbeitsweise eines 12-Kanal- funktionsmeβstandes zur Erfassung und Auswertung schnell ablaufender hämodynamischer Vorgänge

Hemodynamic function studies with radioactive tracers A new set-up, a multichannel function test device, is described for performing hemodynamic function studies with radioactive tracers. After injection of radioactive labelled particles of definite physical and chemical properties, the distribution of radioactivity can be registered simultaneously as function of time at 6 different sites of the body. Each of the 6 detectors used, one of them can be replaced by a fore-arm counter, is equipped with two channels, which can be individually adjusted to the photopeaks of two different radioisotopes. The data are either/not only stored on magnetic tape or/but also fed into a memory unit operating…
The direct effect of magnetic tape ® on pain and lower-extremity blood flow in subjects with low-back pain: A randomized clinical trial
2021
Low-back pain has a high impact on the world population, and solutions are in demand. The behavior of specific physiological processes has been modified using magnetic fields, whether for pain relief, bone consolidation, or improvement of vascularization. The use of tape with magnetic properties could help in these cases. A double-blind randomized clinical trial was designed to use Magnetic Tape® versus placebo Kinesio tape. Blood flow variables were evaluated using pulsed power Doppler ultrasound. Resistance index, pulsatility index, systolic velocity, and diastolic velocity were measured. The pressure pain threshold was measured using algometry in 22 subjects. The results reveal significa…
The Crystal Barrel data acquisition system
1992
The main detector components of the Crystal Barrel (CBAR) experiment at the Low Energy Antiproton Ring (LEAR) at CERN are two proportional wire chambers, a jet drift chamber and an electromagnetic calorimeter composed of 1380 CsI(Tl) crystals, with a total of 4380 analog channels. A description is given of the use of distributed VME-based microcomputers to collect data from the various subdetectors and to merge the full event information in a global event builder. At this level the data are transferred to a mu VAX for tape storage and monitoring. >
Development of Removable Visual Impact Indicator or Polymer Composite Materials
2021
The prototype of removable visual impact indicator for thermoset polymer composite materials is developed, and its characteristics are experimentally determined. The indicator is a fabric tape glued by epoxy to the surface of the polymer composite. The tape is impregnated with a composition that provides a visual response at the place of an impact on the composite surface. Ball-drop tests demonstrated the increase of the magnitude of the visual response with the impact energy at different substrate hardnesses. The shelf-life and mode of the tape storage until commissioning are determined. Peel tests showed the ability to remove a used indicator without damaging the surface of the composite.
