The electric arc furnace (EAF) is one of the popular methods of steel production from steel scraps. The plasma arc is used in EAF to generate heat for melting scarp or direct reduced iron (DRI). The liquid metal is drained from the EAF through the tap hole. Nowadays, it is critical to use Automated/robotic tools for opening the tap hole with oxygen lancing. Because many workers have been blinde...
Spectacular black smokers along the mid-ocean-ridge crest represent a small fraction of total hydrothermal heat loss from ocean lithosphere. Previous models of measured heat flow suggest that 40%–50% of oceanic hydrothermal heat and fluid flux is from young seafloor (0.1–5 Ma) on mid-ocean-ridge flanks. Despite evidence that ridge-flank hydrothermal flux affects crustal properties, ocean chemis...
[1] To explain the much higher denudation rates and valley network development on early Mars (> 3.6 Gyr ago), most investigators have invoked either steady state warm/wet (Earthlike) or cold/dry (modern Mars) end-member paleoclimates. Here we discuss evidence that highland gradation was prolonged, but generally slow and possibly ephemeral during the Noachian Period, and that the immature valley...
Fields of pits, both large and small, in Tombaugh Regio (Sputnik Planitia, and the Pitted Uplands to the east), and along the scarp of Piri Rupes, are examples of landscapes on Pluto where we conclude that sublimation drives their formation and evolution. Our heuristic modeling closely mimics the form, spacing, and arrangement of a variety of Tombaugh Regio’s pits. Pluto’s sublimation modified ...
Landslides take part in weathering and transport processes on Earth as well as on Mars. Prediction of their dynamics remains difficult in spite of many experimental and numerical studies. Numerous numerical works have been carried out on real landslides cases using DTM (Digital Topographic Model) so as to improve our understanding of their development by comparing results with field observation...
Transport of the earth surface material associated with diffusion brings a landform change, and the resulted sediment or debris thickness is approximated by a normal distribution. The essential feature of this geomorphic process is described in terms of the transport distance and the spatial spreading of the masses. A unit mass on a slope may move at a rate b downward and spread at a diffusivit...
SUMMARY This study explores the geomorphological expression and geological context of a normal fault scarp in stable continental region (SCR) which we interpret as having failed large (Mw >7) earthquakes. Records such faulting events an SCR (or even more rapidly deforming regions) are extremely rare, so understanding this feature is international interest. The exceptionally well-preserve...
It is vital to monitor the post-seismic landslides economically and effectively in high-mountain regions for long term. The landslide creep could cause a subtle change of overlying vegetation after earthquake, which will lead spectral characteristics optical remote sensing data. technique can be used areas with dense large range at low cost because it easy obtain multi-temporal, multiple-scale,...
