Results of 92 xerotomographies of the upper air-ways are demonstrated on selected cases of benign and malignant neoplasms. In tomography of the throat we prefer the positive type of development. ...Xerography provides a good insight into site and size of tumors in larynx and pharynx.
We determined the electric form factor ital Gsup ital nsub ital E of the neutron from the quasielastic sup 2H(ital rvec e,ital esup primeital rvec n)sup 1H reaction at a central squared four-momentum ...transfer ital Qsup 2=0.255 (GeV/ital c)sup 2 with a longitudinally polarized electron beam of 868 MeV and a low (similar to0.8%) duty factor. A neutron polarimeter designed and constructed specifically for this experiment was used to measure the sideways polarization of the recoil neutron, which was detected in coincidence with the scattered electron. Theoretical calculations have established that this polarization-transfer technique for quasielastic scattering produces a value of ital Gsup ital nsub ital E that shows little sensitivity to the influence of final-state interactions, meson-exchange currents, isobar configurations, and deuteron structure. The value for ital Gsup ital nsub ital E from this measurement is 0.066plus minus0.036plus minus0.009.
To evaluate the effect of oral anticoagulant therapy on graft patency rate during the first 2 months after bypass surgery 174 patients were randomly assigned to treatment with phenprocoumon (89) or ...to a control group (85) starting on day 7 after bypass surgery. Until day 7 all patients received low dose heparin. There was no significant difference between the two groups with respect to age, sex distribution, number of vessels diseased, left ventricular enddiastolic pressure, preoperative exercise tolerance or number of grafts constructed per patient. All patients underwent angiographic evaluation 8 weeks after bypass surgery. Graft patency rate was 90.4% in the treatment group versus 83.6% in the control group (p less than 0.015). None of the grafts with a flow rate of greater than 90 ml/min was occluded 8 weeks after surgery. Oral anticoagulation improved the patency rate of grafts with a flow of less then 90 ml/min.
CARIBIC (Civil Aircraft for the Regular Investigation of the Atmosphere Based on an Instrument Container) resumed regular measurement flights with an extended scientific payload in December 2004. ...After an automated measurement container was successfully deployed on intercontinental flights using a Boeing 767 from 1997 to 2002, a far more powerful package now is deployed using a new Airbus A340‐600 made available by Lufthansa German Airlines (Star Alliance). The new CARIBIC system will help address a range of current atmospheric science questions during its projected lifetime of 10 years.
European and Japanese scientists are developing a variety of atmospheric chemistry research and monitoring projects based on the use of passenger aircraft. This is a logical approach with a main advantage being that near‐global coverage is obtained, in contrast to limited coverage through research aircraftbased expeditions. Moreover, highly detailed and consistent data sets can be acquired, as compared to satellite observations in general. In addition, even compared to land‐based observatories, operational costs are moderate.
