Storm wave base: The maximum depth at which storm-generated waves impinge the sea floor and are capable of moving sediment. Storm wave base is deeper than fairweather wave base. Stoss face: The inclined surface on the upstream side of bedforms such as ripples and dunes. It is rarely preserved because sediment is continually being removed from ...
The propagation constant of a sinusoidal electromagnetic wave is a measure of the change undergone by the amplitude and phase of the wave as it propagates in a given direction. The quantity being measured can be the voltage, the current in a circuit, or a field vector such as electric field strength or flux density.
Experimental measurements during laboratory tests on salt specimens are important for the design of underground facilities in salt formations. These measurements, especially of the volumetric strain, can be influenced not only by the errors inherent to the experimental work, but also by the material heterogeneity. The natural variability due to the presence of impurities can …
The ssdischarge playa of Sidi El Hani, which belongs to the endorheic system of Mechertate–Chrita–Sidi El Hani, is a NW-SE lengthened depression in the Sahel of Tunisia Fig. 1.It covers an area of approximately 370 km 2 with an average 0.4 m depth (0.8 m in some localities) (Ben Jmaa, 2008, Essefi et al., 2012a, Essefi et al., 2012b).The basin is limited by …
The wave profile of the corrugations of antiextrusion ring 10 at a given radius may be sinusoidal or flat folded plate segments or another suitable, repetitive profile; the ring wave height may be made greater for the smaller radius portion of the ring to facilitate the fabrication of the ring from straight flat strip material. The wave profile ...

Rock mechanics is a multidisciplinary subject combining geology, geophysics, and engineering and applying the principles of mechanics to study the engineering behavior of the rock mass. With wide application, a solid grasp of this topic is invaluable to anyone studying or working in civil, mining, petroleum, and geological engineering.

High in-situ stress and frequent dynamic disturbances caused by the mining process in deep coal mines can easily induce dynamic disasters such as coal burst. We conducted laboratory experiments to assess the effects of the axial stress loading and dynamic cyclic impact loading on the dynamic mechanical properties of burst-prone coals by using a modified split …
Storm wave base was probably relatively shallow. In a fully developed sea, wave base (wavelength divided by two) for deep-water waves with a wavelength of 40 m and wave height of 1.8 m, produced by 40 km/h winds with a fetch of ∼150 km, is ∼20 m, i.e., twice that from 30 km/h winds (e.g., Trujillo and Thurman, 2017, chapter 8).
The presence of wave ripples and other sedimentary structures implies either that the ash was reworked by water shortly after deposition or that it settled through standing bodies of water. The varying thickness of the tuffs reflects undulations in the surface on which they were deposited (Love & Williams, Reference Love, Williams, Friend and ...
Low-noise tone-burst sinusoidal waves were generated using a large-amplitude burst wave generator (RPR-4000, RITEC. Inc., Warwick, GA, USA). After amplifying using a high-power amplifier, the ultrasonic waves of frequency of 5 MHz, 10 MHz, and 20 MHz were sent out by focused transducers with focal lengths of 38 mm, 76 mm, and 25 mm, respectively.
It is applied to give the temperature dependence of C v over the range 0°–1000°K of halite, periclase, brucite, corundum, spinel, quartz, cristobalite, silica glass, coesite, stishovite, rutile, albite, and microcline. The specific heat of the simple Debyelike substances, halite and periclase, is reproduced well by the model.
For fifth-order eustasy a sinusoidal wave with a period of 40,000 years was used, approximating the obliquity cycle. The amplitude of this oscillation (9 m) was constrained by the stacking patterns of the fifth-order cycles, which tend to thin upward toward the top of a sequence, indicating that the relative amplitude had to be less than that ...

Halite-Centurion studies in the USA, and the few data publicly available suggest that an implosion energy of 20 MJ would be needed. These results gave an idea of what should be the energy of the driving mechanism, but left scientists with the problem of how to achieve fusion in a controlled fashion with a fusion reactor.
In the framework of non-destructive-testing advanced seismic imaging techniques have been applied to ultrasonic echo data in order to examine the integrity of an engineered test-barrier designed to be used for sealing an underground nuclear waste disposal site. Synthetic data as well as real multi-receiver ultrasonic data acquired at the test site were processed and …
Terry Hazen's lab is a diverse group of scientific post doctoral fellows, research associates, technicians, and students in microbial ecology and environmental engineering. The primary research emphasis of the lab is basic and applied field microbial ecology, especially as it relates to bioremediation, biofuels, enhanced oil recovery, and water quality.
The ease of deformation of rock salt is related to the trans- lation gliding systems in halite. These are functions of the face-centered cubic lattice. Most commonly halite glides by translation on the dodeca- hedron (110) and the cube (001) planes in a …
