    Instability on a weakening fault (1984)
    Springer

    Notes: Abstract Weakening of a prestressed sawcut in Westerly granite under laboratory condition is accomplished by injecting pressurized fluid into the sawcut. After injection a sequence of stick-slips is observed while the deviatoric stress decreases successively with each stick-slip. On the basis of the experimental observation we develop a model of fault instability due to inhomogeneous and progressive weakening of the fault. According to this model, the fault surface is divided into the ‘slipped’ and the ‘locked’ regions, depending on whether or not the local state of stress satisfies the friction criterion. The average shear stress in the slipped region decreases with time and, in order to maintain a quasi-static equilibrium, shear stress in the remaining ‘locked’ region on the fault surface increases. This situation may last until a critical state of stress on the fault is met, at which a sudden instability (stick0slip) may occur. We suggest that this mechanism of stress transfer may be a viable mechanism of induced seismicity and aftershocks, in addition to the well-known mechanism of a local increase of pore pressure. By comparing the experimental data with model predictions we show that the critical condition for slip instability is when the average shear stress over the ‘locked’ region becomes equal to the value given by the friction criterion. Thus the friction criterion established for slip on fractures on which the state of stress is macroscopically uniform may also be applicable to fractures on which the stress state is macroscopically heterogeneous.

    EFFECT OF SHORT-TERM HIGH CO2 TREATMENT ON THE MARKET QUALITY OF STORED BROCCOLI (1979)
    Oxford, UK : Blackwell Publishing Ltd

    Notes: Broccoli was treated at 5°C with 20, 30 and 40% CO2 for 3 and 6 days soon after harvest, and then transferred to storage in air at 5°C. CO2 injury was severe in samples treated with 40% CO2 for 6 days. Offensive odor and flavor also developed by the end of 6 days' treatment with 30% CO2 but dissipated when the broccoli was transferred to air. CO2 delayed yellowing and loss of both chlorophyll and ascorbic acid, and retarded ethylene production. Except at the level that was injurious to the tissue, CO2 retarded mold growth and had no appreciable effect on compactness, turgor, and opening of the florets.

    Smokehouse Process Conditions for Meat Emulsion Cooking (1987)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of food science 52 (1987), S. 0

    ISSN: 1750-3841

    Notes: The effects of various rates of increase of the smokehouse temperature (ST) (0.42 to 0.98°C/min) and relative humidity (SRH) (1.1 to 3.9%/ min) on the meat emulsion product qualities were investigated. The optimum process conditions were calculated based on the water holding capacity (WHC), emulsion stability (ES), shrinkage, textural parameters and sensory attributes. Least shrinkage was obtained when the product was processed under rapid temperature and relative humidity increase. The WHC was higher when the product was processed at a lower ST. The most stable product was obtained at the lowest ST and the highest SRH. Cohesiveness and elasticity were not affected by ST and SRH, brittleness was unaffected by SRH, and hardness was not influenced by ST. The lowest hardness, chewiness and gumminess were obtained at the highest SRH.

    X-ray diffraction analysis of Si1−xGex/Si superlattices (1992)
    [S.l.] : American Institute of Physics (AIP)
    Journal of Applied Physics 72 (1992), S. 3474-3479

    Notes: Si1−xGex/Si strained-layer superlattices grown by molecular-beam epitaxy on Si substrates were investigated by x-ray double-crystal diffraction and x-ray grazing incidence diffraction. Both coherent and incoherent interfaces between the two components of the superlattices were observed. By fitting computer-simulated double-crystal x-ray-diffraction rocking curves to the experimental data, it is determined that there exist graded variations in both the component thickness ratio t1/t2 (t1 and t2 are the thickness of the Si1−xGex and the Si layers, respectively) and the fraction x in one sample. The x-ray grazing incidence diffraction experiments reveal a lattice strain relaxation of about 27% in another sample. The lattice relaxation and the influence of variations of x and t1/t2 on the rocking curves are discussed.

    Elastodynamic fundamental solutions for anisotropic solids (1994)
    Oxford, UK : Blackwell Publishing Ltd
    Geophysical journal international 118 (1994), S. 0 
    Details
    ISSN: 1365-246X
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Geosciences
    Notes: 3-D and 2-D time-domain elastodynamic fundamental solutions (or Green's functions) for linearly elastic anisotropic materials are obtained by the Radon transform. Fundamental solutions in the frequency domain follow directly by a subsequent evaluation of the Fourier transforms of the time-domain solutions. The solutions are in the form of a surface integral over a unit sphere for 3-D cases and in the form of a contour integral over a unit circle for 2-D cases. The integrals have a simple structure that can be interpreted as a superposition of plane waves. The wavefields can be separated into singular and regular parts. The singular parts correspond to the elastostatic fundamental solutions. The regular parts are bounded continuous functions. The integrals have been evaluated numerically for several examples. The results presented in this paper have direct applications to the formulation of boundary-integral equations for bodies of anisotropic materials and for the subsequent solution of these equations by the boundary-element method.

    Parallel forces induced by waves in ion cyclotron range of frequencies (1995)
    [S.l.] : American Institute of Physics (AIP)

    Notes: A new mechanism is identified for radio frequency (RF) wave induced force and current drive caused by a kinetic flux carried by coherent oscillations of plasma particles. The induced force along a magnetic field line by RF heating of plasmas is calculated with a one-dimensional slab model, and found to be contributed by the plasma power absorption and spatial inhomogeneity. The inhomogeneity term consists of a kinetic flux and a flux related to RF wave helicity injection rate. The effect from the kinetic flux exists only in a warm plasma, whereas, in contrast, the effect from the helicity related flux exists even in a cold plasma. The forces are calculated for both electrons and ions in the ion cyclotron range of frequencies (ICRF), and the effects from the ion cyclotron and the second harmonic resonance are included. © 1995 American Institute of Physics.
