[1] We use campaign and continuous GPS measurements at 49 sites between 1996 and 2010 to describe the long-term active deformation in and near the Nicoya Peninsula, northwestern Costa Rica. The observed deformation reveals partial partitioning of the Cocos-Caribbean oblique convergence into trench-parallel forearc sliver motion and less oblique thrusting on the subduction interface. The norther...

rapeseed (brassica napus l.) is a crop relatively tolerant to salt. the effect of different ratios of nacl/kcl was studied in two cultivars (hyola308 and kristina) of rapeseed in 2002. canola seedlings were grown in hoagland’s solutions, which were salinized by different ratios of nacl/kcl. the treatments or kcl:nacl ratios were 0:0 (control);10:10; 20:0 (total added salt or tas=20 mol.m-3), 0:...

A method of tube joining by plastic deformation has efficient, reliable and environmentally friendly features, so that it is widely applied into the fabrication aviation pipeline. Internal rolling potential to join high strength titanium alloy tubes withstanding pressure medium with better sealing performance. Taking TA18 as case material, this presentation combines numerical modelling experime...

A new combination of factors enhancing the stabilization austenite, including pre-existed austenite among quenched martensite, prior deformation, and partitioning at high temperatures is employed to create a multi-component refined microstructure in medium Mn steel (Fe–4Mn–0.31C–2Ni–0.5Al–0.2Mo, wt.%). The evolution phase fraction during processing are systematically investigated using various ...

Abstract Following observations made in a survey campaign along the Lost River Fault (Idaho, USA) 2019, we integrate both original and previously published data to obtain detailed segmentation of fault sections that failed 1983 Borah Peak earthquake (Mw 6.9). The ruptured topographic surface with an oblique-normal faulting mechanism, activating two SW-dipping segments (Thousand Springs Warm Spr...

Large-scale molecular dynamics (MD) simulations have been utilized to reveal the atomistic deformation mechanisms of a CrCoNi medium-entropy alloy (MEA) with gradient nano-grained (GNG) structure in present study. Strong strain hardening was observed at elasto-plastic transition stage, which could be attributed Masing hardening. After yielding, obvious partitioning tensile detected structure, i...

Great earthquakes rarely occur within active accretionary prisms, despite the intense long-term deformation associated with the formation of these geologic structures. This paucity of earthquakes is often attributed to partitioning of deformation across multiple structures as well as aseismic deformation within and at the base of the prism (Davis et al., 1983). We use teleseismic data and satel...
