The Antrim Coast Road stretching from the seaport of Larne in the East of Northern Ireland has a well-deserved reputation for being one of the most spectacular roads in Europe (Day, 2006). However the problematic geology; Jurassic Lias Clay and Triassic Mudstone overlain by Cretaceous Limestone and Tertiary Basalt, and environmental variables result in frequent instances of slope instability ma...
The quality factor of superconducting radio-frequency niobium cavities decreases with the applied RF field in the medium field range. The medium field Q-slope effect has been investigated by many authors but models, most commonly including thermal feedback, do not fully explain experimental evidence. In this contribution we analyze medium field Q-slope data measured on ISAC-II low beta quarter ...
Abstract Due to technological and safety limitations, there are considerable amounts of coal resources pressed under end slopes in open-pit mines. In recent years, this problem has gradually attracted the attention researchers. How realize efficient recovery side overburden while ensuring stability become an important topic for development mining technology China. A 2D/3D integrated simulation ...
Background: Severe spondylolisthesis is related to high degenerative changes in verte-bral spine. Degenerative spondylolisthesis often is seen with high-sacral slope. This study was conducted to investigate the relationship between high degenerative spondyl-olisthesis and sacral slope.Methods: A cross-sectional prospective study was done in patients with low back pain in Shafa Yahyaian and Sina...
Retrogressive landslide is caused by the lower rock mass sliding, so that upper part loses support, deformed, and starts to slide. In process of highway construction, incised slope often leads retrogressive landslide, determination damage range great significance for control slope. Taking a in Hunan Province as research object, particle flow discrete element used numerically simulate entire fai...
The high-salinity water flowing out of the Mediterranean Sea descends to mid depths in the density-stratified ocean, continues as a narrow jet along the Iberian continental slope, and intermittently detaches large-scale eddies (called "Meddies"). This process is important because it maintains the relatively high mean salinity of a major water mass (the "Mediterranean Intermediate Water") in the...
We study in detail the deformations of a liquid-liquid interface induced by the electromagnetic radiation pressure of a focused cw laser beam. Using a simple linear model of static equilibrium of the interface under the effect of radiation pressure, buoyancy, and Laplace pressure, we explain the observed hump height variations for any value of the optical Bond number Bo=(omega0/lc)2 (lc is the ...
The Middle Atlas Mountains in Morocco are best known for their slope-active movements, where lithology, topographic relief, and seismotectonic likely to cause slope instability problems. This study focused on geomorphological geological investigations palaeo-landslide blocked dammed the Tamourghout river main bed (Taza, Morroco). paper is essential due enormous proportions of landslide also bec...
High quality 3D seismic data are used to assess the significance of mass-transport deposits (MTDs) to the evolution of the Pearl River Mouth Basin (South China Sea). Basal shear surfaces and lateral margins of seven recurrent MTDs are mapped to reveal a general NE-SW transport direction throughout the Late Miocene-Quaternary. A key result of our analysis is the perceived relationship between th...
The traditional slope stability analysis used the Factor of Safety (FS) from the Limit Equilibrium Theory as the determinant. If the FS was greater than 1, it was considered as “safe” and variables or parameters of uncertainty in the analysis model were not considered. The objective of research was to analyze the stability of natural slope, in consideration of characteristics of rock layers and...
