    Elastic interaction of a wedge crack with a screw dislocation (1985)
    [S.l.] : American Institute of Physics (AIP)

    Notes: The elastic field of a semi-infinite wedge crack and its interaction with a screw dislocation under mode III loading conditions are examined. The stress field around the wedge crack is expressed in terms of a wedge stress intensity factor. The rate of falloff of the stress field with distance from the crack tip is found to be a function of the wedge angle. The relationship between the stress intensity factors for the wedge and sharp cracks is derived and used to estimate the magnitude of stress relaxation occurring at the crack tip due to crack blunting. The crack extension force for the wedge crack is calculated and is shown to be zero. The modifications in the stress field and the local wedge stress intensity factor due to the presence of the dislocation are calculated. From the image stress on the dislocation, the condition for the emission of dislocations from the wedge crack is obtained in terms of the critical wedge stress intensity factor for dislocation generation. It is found that the emission of dislocations from the crack tip is more difficult when the crack is blunting.

    Theoretical investigation of the traveling wave excitation in a TE N2 laser (1985)
    [S.l.] : American Institute of Physics (AIP)
    Journal of Applied Physics 57 (1985), S. 1478-1481

    ISSN: 1089-7550
    Source: AIP Digital Archive
    Topics: Physics
    Notes: Theoretical investigation of traveling wave excitation using the property of photon addition has been carried out in a 50-cm-long TE N2 laser tube with ten separated discharge sections. The laser power outputs under traveling wave excitation have been calculated numerically with varying gas pressures from 30 to 85 Torr and applied voltages from 14 to 21 kV, and compared with those of simultaneous excitation. Theoretical results show that the laser peak power increases with increasing applied voltage, and has a maximum value at gas pressure P(approximately-equal-to)60 Torr. The laser pulse width is narrowed and the laser power is doubled under the traveling wave excitation, compared with simultaneous excitation. Experimental confirmation also has been conducted. Experimentally observed gas presssure dependence of output power agrees qualitatively well with theoretical results. The maximum discrepancy in the absolute values between theory and experiment is approximately 50%.

    Notes: Abstract An experimental method is described for the phase determination of x-ray reflections from noncentrosymmetric crystals. This method results from considerations on the phase dependence of line profiles in three-beam reflection-type diffractions for wavelength λ above and below a critical absorption edgeλ E of the heaviest constituent atom in the crystals. A relationS p =S L ·S R for phase determination is derived theoretically and verified experimentally forλ〈λ E ,S p being the sign of the sine of invariant phase,S L the sign defined from the line profile, andS R determined by the rotation of the crystal lattice.

    Chains of single-domain magnetite particles in chinook salmon,Oncorhynchus tshawytscha (1985)

    Notes: Summary Although the presence of magnetite in their tissues is correlated with the ability of different species to detect magnetic fields, proof that the magnetite is involved in magnetoreception has not yet been provided. Using the approach employed to localize and isolate magnetic particles in the yellowfin tuna, we found that single-domain magnetite occurs in chains of particles in tissue contained within the dermethmoid cartilage of adult chinook salmon,Oncorhynchus tshawytscha. The particles are present in sufficient numbers to provide the adult fish with a very sensitive magnetoreceptor system. Magnetite in the chinook can be correlated with responses to magnetic fields in a congeneric species, the sockeye salmon. Based on the presence of the chains of particles, we propose behavioral experiments that exploit the responses of sockeye salmon fry to magnetic fields to test explicit predictions of the ferromagnetic magnetoreception hypothesis.

    A new method of determining the orientation of the parent phase and the habit plane normals (1985)
    Springer
    Journal of materials science 20 (1985), S. 947-954

    Notes: Abstract A new general method is proposed for determining the orientation of a parent crystal and the habit plane normals of a plate-shaped product phase without the aid of X-ray experiments. The determination starts with measuring angles between traces formed by the intersection of product phase variants with the surface of a specimen. The results reported are obtained by applying the method to three specific cases. As one of the applications, the unknown orientation of the habit plane of a 2H-stacking ordered martensite in a Ni3Sn alloy is determined as {3 3 1}.

    Estimation of partial pressure of oxygen inside the graphite furnace used for atomic absorption spectrometry (1985)
    Springer
    Fresenius' Zeitschrift für analytische Chemie 322 (1985), S. 567-573

    Description / Table of Contents: Summary The spontaneity of metal atom formation from metal oxides, both in the condensed phase, via thermal decomposition or reduction by carbon in a graphite furnace, depends on the instantaneous partial pressure of oxygen inside the furnace. Since the partial pressure of the gaseous carbon species is very low, the reaction between carbon and oxygen is determined by heterogeneous, gas-solid reaction. The factors affecting the instantaneous partial pressure of oxygen inside a pulse-heated graphite furnace have been studied by computer simulation. The results suggest that the instantaneous oxygen partial pressure inside the furnace is determined by the initial amount of oxygen and the heating rate of the furnace. The effect of oxygen on the shift of the analyte atomic absorption pulse is also discussed.
    Notes: Zusammenfassung Die spontane Bildung von Metallatomen aus Metalloxiden in der kondensierten Phase durch thermische Zersetzung oder Reduktion durch Kohlenstoff im Graphitofen ist abhängig vom Sauerstoff-Partialdruck innerhalb des Ofens. Da der Partialdruck des gasförmigen Kohlenstoffs sehr niedrig ist, wird die Reaktion zwischen Kohlenstoff und Sauerstoff durch eine heterogene Gas-festReaktion bestimmt. Die Faktoren, die den Sauerstoff-Partialdruck in einem impuls-erhitzten Graphitofen beeinflussen, wurden mit Hilfe einer Computer-Simulation untersucht. Die Ergebnisse zeigten, daß dieser Druck von der anfänglichen Sauerstoffmenge und der Aufheizgeschwindigkeit des Ofens abhängt. Die Wirkung des Sauerstoffs auf die Verschiebung des analytischen AAS-Impulses wird ebenfalls diskutiert.

    Inhibition of epoxidation of carbamazepine by valproic acid in the isolated perfused rat liver (1985)

    Notes: Abstract The effect of valproic acid on carbamazepine epoxidation in the perfused liver was investigated in two separate studies. In study I, significant decreases were observed both in the intrinsic clearance of carbamazepine and the intrinsic formation clearance of carbamazepineepoxide in the presence of therapeutic concentrations of valproate. The same inhibitory effect of valproate was also observed in liver preparations from a group of animals pretreated with carbamazepine. Study II focused on the effect of valproate and carbamazepine on the apparent Michaelis-Menten parameters (V max,m,Km,m)associated with the intrinsic formation clearance of carbamazepineepoxide in the perfused liver. Valproate had no statistically significant effect on either the V max,morthe Km,m of epoxidation, although the Km,m value was 43% higher in the presence of valproate. However, the ratio of V max,m and Km,m (intrinsic formation clearance) was significantly reduced by valproate. The V max,m and Km,m values obtained in study II predicted a significant decrease in the intrinsic formation clearance of carbamazepineepoxide, consistent with the results of study I. Carbamazepine pretreatment was associated with significant increases in apparent V max,m and Km,m of epoxide formation.
