Monomeric HPt domains have no enzymatic activity of their own and act purely as phosphate shuttles, [10] [4] while the dimeric Spo0B is catalytic; its phosphotransfer rate to the recipient response regulator is dramatically accelerated compared to histidine phosphate. [11]
High-pressure torsion (HPT) is a severe plastic deformation technique used to refine the microstructure of materials by applying both high pressure and torsional strain. [1] HPT involves compressing a material between two anvils while simultaneously rotating one of the anvils, inducing shear deformation. [ 2 ]
During the constrained HPT process, the material experiences shear deformation between a fixed and a rotating anvil, without losing its original dimensions. High pressure torsion (HPT) can be traced back to the experiments that won Percy Bridgman the 1946 Nobel Prize in Physics, though its use in metal processing is considerably more recent. In ...

HPT with Field Barriers; A more recent enhancement for intrinsically safe applications is the High Power Trunk (HPT) with field-based field barriers (FBs), which limits power at the spur, rather than the trunk. This method significantly changes the equation for end users of Fieldbus in hazardous settings.
The hypothalamic–pituitary–thyroid axis (HPT axis for short, a.k.a. thyroid homeostasis or thyrotropic feedback control) is part of the neuroendocrine system responsible for the regulation of metabolism and also responds to stress. As its name suggests, it depends upon the hypothalamus, the pituitary gland, and the thyroid gland.
