EXPERIMENTAL AND MOLECULAR DYNAMIC STUDY OF GRAIN REFINEMENT AND DISLOCATION SUBSTRUCTURE EVOLUTION IN HSLA AND IF STEELS AFTER SEVERE PLASTIC DEFORMATION

In this study, large-scale molecular dynamic simulations were cmpk bolus performed to analyze the dislocation substructure interaction with various types of obstacles present in microalloyed steels during severe plastic deformation.Specifically, fully functional numerical models of the atomic upsetting test were developed, with particular emphasis

Abstract Background In-vivo single voxel proton magnetic resonance spectroscopy (SV 1H-MRS), coupled with supervised pattern recognition (PR) methods, has been widely used in clinical studies of discrimination of brain tumour types and follow-up of patients bearing abnormal brain masses.SV 1H-MRS provides useful biochemical information about the me

The Ca(2+)-sensing receptor (CaSR) regulates Ca(2+) homeostasis in the body by monitoring extracellular levels of Ca(2+) ([Ca(2+)]o) and giant lindt chocolate amino acids.Mutations at the hinge region of the N-terminal Venus flytrap domain (VFTD) produce either receptor inactivation (L173P, P221Q) or activation (L173F, P221L) related to hypercalcem

The DC/DC converter is the core part of the two-stage electric vehicle Onboard Charger.At present, the phase-shifted full-bridge soft-switching DC/DC converter has problems such as difficulty in commutation of the lagging leg, voltage fluctuation on the secondary side of the transformer, and low efficiency.A full-bridge DC/DC converter with two cla
