    Notizen: A new design for radiation-sensing field-effect transistors (RADFETs) is presented, involving the use of very thick silicon nitride layers deposited on top of a high-quality thermal silicon dioxide. In contrast to previous RADFET fabrication procedures, no attempt was made to introduce hole traps into the thermal oxide. Instead the trapping layer at the nitride oxide interface was used to store the positive charge which forms the basis for operation of the RADFET. Data is presented which shows hole transport in the thermal oxide. Models explaining the field dependence of the response and the saturation behavior of the dual dielectric device are given. These RADFETs are more stable than any previously described in the literature and have a sensitivity of 86 μV/rad dose at room temperature.

    Notizen: Over the past three years, the total TMX-U diagnostic data base has grown to exceed 10 Mbytes from over 1300 channels; roughly triple the originally designed size. This acquisition and processing load has resulted in an experiment repetition rate exceeding 10 min per shot using the five original Hewlett–Packard HP-1000 computers with their shared disks. Our new diagnostics tend to be multichannel instruments, which, in our environment, can be more easily managed using local computers. For this purpose, we are using HP series 9000 computers for instrument control, data acquisition, and analysis. Fourteen such systems are operational with processed format output exchanged via a shared resource manager. We are presently implementing the necessary hardware and software changes to create a local area network allowing us to combine the data from these systems with our main data archive. The expansion of our diagnostic system using the parallel acquisition and processing concept allows us to increase our data base with a minimum of impact on the experimental repetition rate.

    Notizen: A commercial database software package has been used to create several databases and tools that assist and enhance the ability of experimental physicists to analyze data from the Tandem Mirror Experiment-Upgrade (TMX-U) experiment. This software runs on a DEC-20 computer in M-Divisions's User Service Center at Lawrence Livermore National Laboratory (LLNL), where data can be analyzed off line from the main TMX-U acquisition computers. When combined with interactive data analysis programs, these tools provide the capability to do batch-style processing or interactive data analysis on the computers in the USC or the supercomputers of the National Magnetic Fusion Energy Computer Center (NMFECC) in addition to the normal processing done by the TMX-U acquisition system. One database tool provides highly reduced data for searching and correlation analysis of several diagnostic signals within a single shot or over many shots. A second database tool provides retrieval and storage of unreduced data for use in detailed analysis of one or more diagnostic signals. We will show how these database tools form the core of an evolving off-line data analysis environment on the USC computers.

    Notizen: The object of this double-blind, multicentre study was to compare duodenal ulcer healing rates after 2 and 4 weeks of treatment with either 20 mg omeprazole o.m. or 150 mg ranitidine b.d. One hundred and eighty-one patients were randomized: 91 received omeprazole and 90 received ranitidine.In a per protocol analysis at 2 weeks, 63% of the patients were healed on omeprazole and 65% of the patients were healed on ranitidine (N.S.); at 4 weeks 91% were healed in the omeprazole group and 96% were healed in the ranitidine group. There were no differences in ulcer symptom relief between the two groups. There were no significant changes in laboratory values in either of the groups. Adverse events were few and mainly mild and transient.We conclude that both omeprazole (20 mg o.m.) and ranitidine (150 mg b.d.) result in rapid, ulcer healing rates.

    Notizen: Abstract The relative yield of high transverse momentum protons measured inpp interctions at the CERN ISR is calculated in the framework of simple parton models. Whereas models based exclusively on quark and gluon scattering fail to describe the data, the hypothesis of diquark scattering provides a quantitative understanding of the measured dependences on transverse momentum, polar angle, and centre-of-mass energy. Different assumptions on diquark structure functions are tested.

    Beschreibung / Inhaltsverzeichnis: Zusammenfassung In unserer Versuchsanordnung haben wir ein Modell einer in traabdominellen heterotopen Pankreas-Duodenum-Autotransplantation geschaffen. Zwei Hunde überlebten für lange Zeit in befriedigendem Zustand. Zu Anfang, unmit telbar nach Pankreas-Autotransplantation, konnte ein Gewichtsverlust infolge exokriner Pankreasunterfunktion beobachtet werden. 3 Monate später hatten die Tiere wieder ihr Ausgangsgewicht. Im Gegensatz zur exokrinen Funktion konnte die endokrine über den gesamten Beobachtungszeitraum, mit Ausnahme weniger Tage unmittelbar nach der Transplantation, erhalten werden. Im Gegensatz zu Kontrolltieren zeigte sich beim Tolbutamid-Test eine signifikante Verlängerung der Hypoglykämie. Der Glucosetoleranz Test verlief normal. Eine Fibrosierung nach Pankreas-Autotransplantation konnte nicht beobachtet werden. Dieses experimentelle Modell ist sehr hilfreich für die Langzeit Beobachtung einer heterotopen Pankreas-Autotransplantation. Denervierung und Unterbrechung der lymphatischen Bahnen scheinen zwar einen vorübergehenden, jedoch keinen dauerhaften Einfluß auf die endokrine oder exokrine Pankreasfunktion zu haben.
    Notizen: Summary We have described a technique of one stage intraabdominal heterotopic pancreaticduodenal autotransplantation which has resulted in long term survival of dogs in good health. Malnutrition related to pancreatic exocrine hypofunction occurs initially but gradual recovery by 3 months nutrition is normal. In contrast, endocrine function is well preserved throughout the postoperative period except for a few days immediately after transplantation. Tolbutamide testing showed a significant prolongation of hypoglycemia as compared to controls although glucose tolerance curves were normal. There was no fibrosis after pancreas- autotransplantation. This experimental model is useful for long term evaluation of heterotopic transplantation of the pancreas. Denervation and lymphatic interruption of the pancreas may cause a transient but not definitive influence on pancreatic endocrine or exocrine function.
