    Notes: Abstract The neutron-irradiation effects on C60 fullerite powder were studied by positron lifetime spectroscopy. Below 0.5 ns, a single lifetime of 382±1 ps was found for the unirradiated annealed sample and two components were resolved after neutron irradiation with a dose of 2×1016 n/cm2. Possible origins of these components are briefly discussed.

    Notes: Abstract. The neutron-irradiation effects on C $_{60}$ fullerite powder were studied by positron lifetime spectroscopy. Below 0.5 ns, a single lifetime of $382\pm1$ ps was found for the unirradiated annealed sample and two components were resolved after neutron irradiation with a dose of $2\times 10^{16}$ n/cm $^2$ . Possible origins of these components are briefly discussed.

    Description / Table of Contents: Zusammenfassung Wegen des grundsätzlich immer vorhandenen Wärmeaustausches mit der Umgebung ist der gewöhnliche Zweistoff-Wärmeaustauscher als Sonderform des Dreistoff-Wärmeaustauschers aufzufassen. In zahlreichen Situationen führt der Umgebungseinfluß zu merklich vergrößerten oder reduzierten Austauschflächen, je nach dem Zweck des Prozesses. Darüberhinaus läßt sich eine gewünschte Temperaturänderung unter gewissen Bedingungen überhaupt nicht mehr erreichen. Für einige typische Stromführungen werden diese Bedingungen hergeleitet; damit kann man direkt und ohne größeren Rechenaufwand feststellen, ob und für welche Parameterkombinationen ein angestrebter Austauschprozess realisierbar ist.
    Notes: Abstract Strictly speaking, the common two-fluid heat exchanger is a special version of a three-fluid exchanger because the environment also participates in the energy exchange. In a number of situations this effect is significant and leads to either reduced or increased area requirements, depending on the purpose of the exchange operation. With certain combinations of the system parameters it is even impossible to achieve an envisaged temperature change. For some typical flow arrangements these combinations are established in an analytic form so that one can rapidly assess the feasibility of a desired process without actually performing the rather tedious design calculations.

    Notes: Abstract. Denitrification processes were measured by the acetylene-blockage technique under changing flood conditions along the aquatic/terrestrial transition zone on the Amazon floodplain at Lago Camaleão, near Manaus, Brazil. In flooded sediments, denitrification was recorded after the amendment with NO3 − (100 μmol liter−1) throughout the whole study period from August 1992 to February 1993. It ranged from 192.3 to 640.7 μmol N m−2 h−1 in the 0- to 5-cm sediment layer. Without substrate amendment, denitrification was detected only during low water in November and December 1992, when it occurred at a rate of up to 12.2 μmol N m−2 h−1. Higher rates of denitrification at an average rate of 73.3 μmol N m−2 h−1 were measured in sediments from the shallow lake basin that were exposed to air at low water. N2O evolution was never detected in flooded sediments, but in exposed sediments, it was detected at an average rate of 28.3 μmol N m−2 h−1 during the low-water period. The results indicate that under natural conditions there is denitrification and hence a loss in nitrogen from the Amazon floodplain to the atmosphere. Rates of denitrification in flooded sediments were one to two orders of magnitude smaller than in temperate regions. However, the nitrogen removal of exposed sediments exceeded that of undisturbed wetland soils of temperate regions, indicating a considerable impact of the flood pulse on the gaseous turnover of nitrogen in the Amazon floodplain.

    Description / Table of Contents: Zusammenfassung 12 Probanden (11 Frauen und 1 Mann) mit Cushing-Syndrom, die 1960/61 eingehend psychiatrisch untersucht worden sind, wurden im Jahre 1976 bezüglich psychischer Befunde nach der Behandlung des Cushing-Syndroms nachuntersucht. 10 Probanden wurden mit Adrenalektomie behandelt, 1 Probandin nur mit Radiotherapie der Hypophyse und 1 Probandin hat jede Behandlung verweigert. Die Beobachtungsdauer vom Zeitpunkt der Behandlung bis zur Nachuntersuchung oder bis zum Tod (5 Probanden) beträgt im Mittel 15 2/3 Jahre. Bei 7 Probanden gelang es, die überschießende Hormonproduktion der Nebennierenrinde zu beseitigen. Entsprechend war der weitere Verlauf günstig mit völliger Wiederherstellung der Arbeitsfähigkeit. Die Erscheinungen des endokrinen Psychosyndroms bildeten sich weitgehend zurück. Eine dauernde Veränderung der Persönlichkeit wurde nicht beobachtet und die vitale Abhängigkeit von der hormonalen Substitution wurde gut ertragen. Bei 4 von 5 Probanden mit ungünstigem Verlauf war es nicht gelungen, die Nebennierenrindenhormonproduktion zu normalisieren. Im Laufe weniger Jahre kam es zur Invalidität und Pflegebedürftigkeit. Es bildete sich ein mehr oder weniger deutliches organisches Psychosyndrom aus. Im Gegensatz zum Langzeitverlauf der Hypophysen-insuffizienz, wo unspezifische Persönlichkeitsfaktoren einen wichtigen Einfluß haben, hängt beim Cushing-Syndrom die Spätprognose ganz über-wiegend von der erfolgreichen Beseitigung der pathologischen Produktion von NNR-Hormonen ab. Die künstliche Substitution bedeutet in bezug auf das seelische Leben nicht notwendigerweise einen Nachteil.
    Notes: Summary Twelve patients with Cushing's syndrome (11 females, 1 male) who were examined for psychopathologic alterations in the course of the endocrine disease during the years 1960/61, were reexamined in 1976 regarding psychiatric sequelae after treatment. Ten patients had been treated by adrenalectomy, one patient by radiotherapy of the hypophysis, and one patient had refused any treatment. The average lapse of time from operation to reexamination or death (five patients) was 15 2/3 years. In seven patients it had been possible to stop completely the excessive production of adrenal hormones. Correspondingly the long-term result was favorable, with complete recovery of the ability to work. The previous symptoms of the endocrine psychosydrome disappeared almost completely. There was no permanent alteration of personality and the vital dependence on hormonal substitution was well tolerated. In four of the five patients with an unfavorable course of the disease it had not been possible to stop the excessive production of adrenal hormones. These patients became increasingly invalid and had to be cared for. Symptoms of chronic organic brain syndrome developed. In contrast to the course of panhypopituitarism where nonspecific personality factors are of considerable importance, in Cushing's syndrome the long-term prognosis depends entirely on the successful stoppage of the overproduction of adrenal hormones. The artificial substitution is not necessarily a disadvantage for the psychic functioning of the patient.

    Notes: Abstract Data from BEBC experiments are combined to provide large statistics for neutrino interactions. ChargedD * mesons are produced in (1.22±0.25)% of neutrino and (1.01±0.31)% of antineutrino charged current interactions. The mean fraction of the hadronic laboratory energy taken by theD *+ in these events is 0.59±0.03±0.08. Less than 18% of all chargedD * mesons from (anti)neutrino interactions are found to be daughters ofD **0 (at the 90% confidence level).
