    Shallow subsurface structure of the 2009 April 6Mw 6.3 L’Aquila earthquake surface rupture at Paganica, investigated with ground-penetrating radar (2011)

    Publication Date: 2021-11-09
    Description: The shallow subsurface structure of the 2009 April 6 Mw 6.3 L’Aquila earthquake surface rupture at Paganica has been investigated with ground penetrating radar to study how the surface rupture relates spatially to previous surface displacements during the Holocene and Pleistocene. The discontinuous surface rupture stepped between en-echelon/parallel faults within the overall fault zone that show clear Holocene/Pleistocene offsets in the top 10 m of the subsurface. Some portions of the fault zone that show clear Holocene offsets were not ruptured in 2009, having been bypassed as the rupture stepped across a relay zone onto a fault across strike. The slip vectors, defined by opening directions across surface cracks, indicate dip-slip normal movement, whose azimuth remained constant between 210◦ and 228◦ across the zone where the rupture stepped between faults. We interpret maximum vertical offsets of the base of the Holocene summed across strike to be 4.5 m, which if averaged over 15 kyr, gives a maximum throw-rate of 0.23–0.30 mm yr–1, consistent with throw-rates implied by vertical offsets of a layer whose age we assume to be ∼33 ka. This compares with published values of 0.4 mm yr–1 for a minimum slip rate implied by offsets of Middle Pleistocene tephras, and 0.24 mm yr–1 since 24.8 kyr from palaeoseismology. The Paganica Fault, although clearly an important active structure, is not slipping fast enough to accommodate all of the 3–5 mm yr–1 of extension across this sector of the Apennines; other neighbouring range-bounding active normal faults also have a role to play in the seismic hazard.

    Notes: A new second-order accurate method for the solution of two-point boundary value problems on a uniform mesh is given; the local truncation error is obtained for use with the deferred correction process. The method is compared with existing second-order techniques and is shown to produce more accurate results for a number of linear and nonlinear example problems.

    Prediction of electrodeposition rates from an impinging jet (1996)

    Notes: A mathematical model and numerical algorithm are developed to predict electrodeposition rates from a 2-D jet of electrolyte that impinges on a flat surface. The principal situations of interest are for applied voltages that produce current densities below the limiting current. The motion is assumed to be at high speed with the jet inducing a thin laminar boundary layer on the surface; a progressively thinner concentration layer and an electrochemical double layer near the surface are accounted for. Two cases, corresponding to a submerged and unsubmerged jet, are considered. A boundary integral method is used to compute the current density along the plate in a general iterative numerical procedure coupled to the solution of the hydrodynamic, concentration and electrochemical boundary layers. The results show that relatively high deposition rates occur near the point of impingement and that altering the jet angle relative to the surface influences local electrodeposition rates significantly.

    Fluid friction in noncircular ducts (1957)

    Notes: Pressure drop due to fluid friction has been measured in a smooth tube; in six smooth concentric annuli; and between smooth, parallel, flat plates. The data cover the viscous, transition, and lower turbulent ranges of flow. Friction factors are in agreement with theory in the viscous range and can be correlated uniquely in the fully turbulent range by means of a modified hydraulic radius concept. Limits of the transition region in annuli are functions of the ration of inner and outer radii. Correlations in the fully turbulent range permit friction factors for the noncircular ducts to be predicted within the uncertainty of smooth-tube data. Such factors can be used for the prpose of correlating other variables as well as for direct calculation of pressure drop.

    Correlation of local velocities in tubes, annuli, and parallel plates (1958)
    Hoboken, NJ : Wiley-Blackwell

    Notes: A consistent method is presented for predicting local velocities in smooth tubes, concentric annuli, and parallel plates. Consideration is limited to the steady, isothermal, fully turbulent flow of constant-density fluids. Experimental data show the proposed correlation to be indepdent of Reynolds number and radius ratio. Intermediate quantities, calculated from friction data, permit local velocities to be determined over a wide range of operating conditions.

    Notes: Profiles of mean local velocities have been experimentally determined in a smooth, concentric, horizontal annulus having a radius ratio of 0.331. The test fluid was water at room temperature flowing steadily at Reynolds numbers in the viscous, transition, and lower turbulent ranges. The transitional profiles, obtained by means of an impact probe, are summarized and discussed. Limits of the transition zone are established, and variation of the radius of maximum velocity with Reynolds number is confirmed.

    Studies in optical properties and optical radiation hardness of polyorganosiloxanes (1992)

    Notes: A variety of polyorganosiloxanes containing dimethyl, diphenyl, and methylphenyl substituents were studied to determine transparency and optical radiation hardness. Siloxanes show superior optical radiation hardness when compared to optical thermoplastics such as PMMA. Transparency is diminished in polymers containing diphenyl units. This is attributed to the inability to remove traces of the crystalline monomer. Methylphenyl polymers are highly transparent. The maximum attainable refractive index in transparent systems is 1.53.

    The unimolecular dissociation of 3,4-dihydro-2H-pyran over a wide temperature range (1995)
    New York, NY : Wiley-Blackwell

    Notes: The thermal decomposition of 3,4-dihydro-2H-pyran (DHP, C5H8O) has been investigated by two methods: in shock waves with the laser-schlieren technique using mixtures of 5 and 10% DHP in krypton over 900-1500 K, 110-560 torr; in a flow tube having a reaction pressure 0.5 torr above atmospheric using the decomposition of allylethyl ether as an internal standard, and covering 663-773 K. The retro-Diels-Alder dissociation to the stable acrolein and ethylene is the dominant channel for all conditions. Precise rate constants (rms deviation of 10%) were obtained for this process over the indicated temperature ranges. Unimolecular falloff is evident in the shock-tube results, and RRKM calculations also predict a slight falloff at the lower temperatures. These RRKM calculations use a routine vibration model transition state and agree closely with the high-temperature data when 〈ΔE〉down is a fixed 400 cm-1. Arrhenius expressions for k∞ derived from the two measurements are in close accord and also consistent with most previous studies of this reaction. © 1995 John Wiley & Sons, Inc.
