Luminescence in slipped and dislocation-free laser-annealed silicon

Photoluminescence of cw laser-annealed silicon shows a dramatic difference in electronic behavior of the reconstructed material depending upon either creation or suppression of dislocations. Beyond a critical exposure time slip appears, and the luminescence of these samples is dominated by dislocation-related defect levels.

Variation of interlayer slip in space and time during flexural folding

This paper describes the results of an experiment which was performed with a Plasticine model to investigate the progressive evolution of flexural-slip folds. The model analyses the relationship between bulk shortening and the amount of flexural slip on fold limbs and in hinge zones. In the light of the experimental results, the theoretical relationship between limb dip and angular shear strain proposed by Ramsay (1967, p. 393) needs modifying to take into account the effect of hinge dilation and limb thinning at large deformations.

Recent crustal movements in the Sierra Nevada—Walker lane region of California—Nevada: Part i, rate and style of deformation

This review of geological, seismological, geochronological and paleobotanical data is made to compare historic and geologic rates and styles of deformation of the Sierra Nevada and western Basin and Range Provinces. The main uplift of this region began about 17 m.y. ago, with slow uplift of the central Sierra Nevada summit region at rates estimated at about 0.012 mm/yr and of western Basin and Range Province at about 0.01 mm/yr. Many Mesozoic faults of the Foothills fault system were reactivated with normal slip in mid-Tertiary time and have continued to be active with slow slip rates. Sparse data indicate acceleration of rates of uplift and faulting during the Late Cenozoic. The Basin and Range faulting appears to have extended westward during this period with a reduction in width of the Sierra Nevada. The eastern boundary zone of the Sierra Nevada has an irregular en-echelon pattern of normal and right-oblique faults. The area between the Sierra Nevada and the Walker Lane is a complex zone of irregular patterns of hörst and graben blocks and conjugate normal-to right- and left-slip faults of NW and NE trend, respectively. The Walker Lane has at least five main strands near Walker Lake, with total right-slip separation estimated at 48 km. The NE-trending left-slip faults are much shorter than the Walker Lane fault zone and have maximum separations of no more than a few kilometers. Examples include the 1948 and 1966 fault zone northeast of Truckee, California, the Olinghouse fault (Part III) and possibly the almost 200-km-long Carson Lineament. Historic geologic evidence of faulting, seismologic evidence for focal mechanisms, geodetic measurements and strain measurements confirm continued regional uplift and tilting of the Sierra Nevada, with minor internal local faulting and deformation, smaller uplift of the western Basin and Range Province, conjugate focal mechanisms for faults of diverse orientations and types, and a NS to NE—SW compression axis (σ1) and an EW to NW—SE extension axis (σ3).

Determination of maximum earthquake magnitude

A method is proposed to utilize the geologic record of fault displacement along with fault length to estimate the maximum magnitude earthquake that can be expected on an active fault. The method uses seismic moment as the link between geologic data and earthquake statistics. Several examples illustrate that faults of comparable length but different total slip in Holocene time have significantly different earthquake potentials.

First Aid for Drivers

It is a sad fact that victims of accidents continue to die on our roads because people do not know what to do when confronted with traffic injuries. The best hospital is of no use if the patient is already dead or beyond help. This, in Australia, is highlighted by the fact that most road deaths occur on highways (two thirds in New South Wales) and often far from the nearest properly staffed and equipped hospital. Under these conditions the lives of victims can depend on the right measures taken by a passerby, because he has a most important weapon in his hand— time. <h3>Fix the Time.</h3> A glance at the clock is the first thing anyone arriving at an accident should do. In the excitement, time slips away quickly and it is very difficult later to pinpoint the time of the accident. Witnesses vary greatly in their recollection. Yet

Experimental Study of Static and Dynamic Friction Between Sand and Typical Constuction Materials

Abstract The limiting contact friction between sand and steel, cement mortar, graphite, and teflon surfaces was measured in the laboratory. The coefficients of (wall) friction were obtained using static and dynamic loadings with particular reference to conditions at the time slip was initiated. The coefficient of friction increases with the surface roughness and angularity of the sand grains, and as the roughness of the contact surface increases with respect to the size of the sand particles. For steel and mortar surfaces dynamic friction was greater than static friction by about 20 percent unless the surface was sufficiently rough that sand/sand slip was approached. The (static) angle of shearing resistance was the upper limit of the coefficient of friction for all static and dynamic tests where slip was initiated from 1–2 ms to 5 min (loading rates from 5 × 105 to 0.5 psi/min). Under static loading conditions teflon and graphite reduced wall friction by one-half to one-third; at high loading rates graphite was a more effective lubricant than teflon.

An open letter on teaching machines and programed instruction

Each generation feels the pressure of time—to do, to make, to remake, and to perfect the world within a few short years. As each generation leaves its mark, large or small, the history of mankind records, and time slips away. The challenge persists. But few generations have been challenged as seriously as that of the present, for time itself seems accelerated.
