    Accurate nonadiabatic couplings for H3: Application to predissociation (1999)
    College Park, Md. : American Institute of Physics (AIP)

    Notes: We report the results of an ab initio calculation, using analytic techniques, of nonadiabatic couplings for H3 between the degenerate 2E′ ground state and the 2s(2A1′), 3s(2A1′) and 3p(2E′) Rydberg states. The calculations employed extensive correlated wave functions that accurately reproduced the energy levels of these states. We have used these couplings as input to a two-dimensional wave packet calculation of dissociation dynamics in order to predict the predissociation lifetimes and final state vibrational distributions produced by the predissociation. A significant isotope effect is found in the final vibrational distributions produced from H3 and D3 predissociation. © 1999 American Institute of Physics.

    Uptake of phenoxyacetic acid by Penicillium chrysogenum (1995)

    Notes: Abstract  The uptake of phenoxyacetic acid by two different strains of Penicillium chrysogenum was studied. Phenoxyacetic acid (POA) was taken up by P. chrysogenum in a defined medium. Plots of initial velocity of POA uptake versus external substrate concentration, in the range 2–5000 μM, gave linear plots. Uptake of POA by induced and uninduced cells was identical. The initial velocity of POA uptake decreased as the pH of the suspension was increased from 5.4 to 7.2; the decrease closely paralleled the decline in the non-ionic form of the acid over this pH range. The initial velocity of POA uptake was not affected by the presence of phenylacetic acid. POA uptake proceeded until the cellular concentration was equal to the external concentration. It is concluded that POA is passively transported into P. chrysogenum by unmediated diffusion.

    Description / Table of Contents: Zusammenfassung Histiocytome besitzen eine auffallend starke proteolytische Aktivität. Elektrophoretische und immunologische Untersuchungen haben ergeben, daß die proteolytische Aktivität des Histiocytoms mindestens teilweise durch eine Arylamidase hervorgerufen wird, die früher als “Aminopeptidase I” beschrieben wurde. Dieses Enzym ist ein Glykoprotein, das in bezug auf Antigenstruktur, Kohlehydratbausteine, Molekulargewicht und elektrophoretische Beweglichkeit bereits näher charakterisiert worden ist. Die Aminopeptidase I kommt in verschiedenen Geweben vor, unabhängig davon, ob diese ektodermaler, mesodermaler oder entodermaler Herkunft sind.
    Notes: Summary Histiocytomas display a remarkably strong proteolytic activity. Electrophoretic and immunological studies revealed that this proteolytic activity is due, at least partially, to the presence of an arylamidase, previously described as “aminopeptidase I”. This enzyme has been identified in various tissues of ectodermal, mesodermal and entodermal origin.

    Notes: Summary Transition studies in polymers by inverse gaschromatography showed a characteristic pressure-jump in the carrier with constant flow-rate, which may be related to the dilatometric behaviour of the polymer in the transition region.

    Laparoscopic intracorporeal anastomosis in the colon using the biofragmentable anastomotic ring – an animal study (1996)

    Description / Table of Contents: Résumé. Cette étude expérimentale a pour but de déterminer l'utilité d'une technique d'anastomose totalement laparoscopique du côlon avec l'aide de l'anneau d'anastomose biofragmentable Valtrac et avec l'emploi d'un nouvel applicateur. Après résection colique intra-corporelle fermée avec l'agrafeuse linéaire et après mise en place de bourses, l'extrémité proximale et distale du còlon est ré-ouverte pour permettre la mise en place de l'anneau de Valtrac permettrant de compléter l'anastomose intra-corporelle. Cette technique a été testée chez 8 cochons. Six animaux n'ont développé aucune complication per- ou postopératoire alors que deux cochons ont développé une péritonite fatale suite à une insuffisance de l'anastomose chez l'un des animaux et une sténose anastomotique par déplacement de l'anneau de Valtrac. Les résultats de cette étude montrent que la manipulation de l'anneau anastomotique biofragmentable est facilitée par l'usage du nouvel applicateur. Dans les cas non compliqués, l'endoscopie et l'histologie ont montré une guérison per primam avec peu de sclérose et aucune de sténose anastomotique.
    Notes: Abstract. This experimental study examines the usefulness of a totally laparoscopic anastomotic technique in the colon with the aid of the biofragmentable anastomotic Valtrac ring and a newly developed applicator device. Following closed intracorporeal colonic resection with the linear stapler and subsequent re-opening of the proximal and distal bowel ends after placement of a pursestring suture, intracorporeal anastomosis was completed with the Valtrac ring. The technique was tested in 8 pigs. 6 pigs had no intra- or postoperative complications, while 2 pigs developed fatal peritonitis following anastomotic insufficiency in one pig and anastomotic stenosis caused by tilting of the Valtrac ring in the other animal. The results of the study show that handling of the biofragmentable anastomotic ring is facilitated by the use of the new application system. In the uncomplicated case, endoscopy and histology revealed bland healing with little scarring, and no evidence of an anastomotic stenosis.

    Notes: Abstract: Excited states of the nucleus ν123Xe have been investigated with the fusion–evaporation-reaction ν110Pd(ν18O,5n)ν123Xe at 86 MeV beam energy, using the compton-suppressed Nordball-multidetector-system at the Niels-Bohr-Institute in Risø, Denmark. The level scheme of ν123Xe was extended up to a level of tentative 53/2+ħ. Four excited bands of 3-quasiparticle-character were observed. Analyzing the directional correlation information, we could assign spin- and parity-values to all observed bands in ν123Xe. The observed band structures fit well into systematics of the neighboring nuclei ν125Xe and ν127Xe.
