Shock oscillation mechanisms of highly separated transitional shock-wave/boundary-layer interactions
… separations. These conditions combined induce a shock oscillation with frequencies approximately matching the blade's natural structural frequencies. This resonance causes excitation and vibrations, which, if not mitigated, can lead to fatigue and potential structural failure. This dissertation …

Protection of Artemia from vibriosis by heat shock and heat shock proteins
… losses. During my work the application of heat shock proteins (Hsps) as an approach to disease control in aquaculture was explored, with gnotobiotic brine shrimp Artemia larvae as the model organism. The thesis contains several findings, featuring the interesting observation that a non-lethal …

UNM Shock Tube Modernization
The UNM shock tube in the Mechanical Engineering department has been in continuous operation since its creation in 2007. During this time, significant discoveries in the field of Richtmyer-Meshkov instabilities has been made with this shock tube. While conducting these experiments, limitations on …

LASER SHOCK IMPRINTING OF METALLIC NANOSTRUCTURES AND SHOCK PROCESSING OF LOW-DIMENSIONAL MATERIALS
Laser shock imprinting (LSI) is proposed and developed as a novel ultrafast room-temperature top-down technique for fabricating and tuning of plasmonic nanostructures, and processing of one-dimensional semiconductor nanowires and two-dimensional crystals. The technique utilizes a shock pressure …

The value of shock index, modified shock index and age shock index to predict critical outcomes in a district level emergency centre
… admission and in-hospital mortality. The shock index (SI), modified shock index (MSI) and age shock index (ASI) are clinical markers derived from vital signs and correlate with tissue perfusion in critically ill patients. This study aimed to assess the value of SI, MSI and ASI to predict …

Experimental Investigation of Shock-Shock Interactions over a 2-D Wedge at M = 6
… and sweep angle on peak heating rates due to shock-shock interactions were investigated in the NASA Langley Research Center 20-inch Mach 6 Air Tunnel. The fin model leading edges, which represent cylindrical leading edges or struts on hypersonic vehicles, were varied from 0.25 inches to 0.75 …

Shock estimation in supersonic vehicles
… low order model for the estimation of the shock structure generated by vehicles flying in the supersonic and hypersonic regimes. Taking as inputs the geometry and the flow conditions, the proposed approach addresses, in one cohesive methodology, attached and detached shocks in two and three …

Shock isolation using switchable stiffness
… control strategy applied to the problem of shock isolation. This is based on the principle that the stiffness and mass are the principal physical properties that control the passive system shock response. The problem of shock response control is divided in two stages. Firstly, the maximum …

Shock Physics in Compressible Solids
… explores the physics of compressive and tensile shock waves in compressible solids, focusing on thermoelastic (TE) and thermoviscoelastic (TVE) materials with and without rheology. Shock phenomena in compressible solids are inherently complex, involving nonlinear wave interactions, dissipation …

CONDITIONED REINFORCEMENT FROM SHOCK TERMINATION.
… or not a stimulus paired with the termination of shock would acquire a positive conditioned reinforcing function. Previous investigators have suggested that a stimulus paired with shock termination must increase the frequency of a response upon which it is made contingent. This test for …

Reactive solids under shock compression
… and energy absorbing molecular materials, under shock compression are explored. To drive shock waves into target materials, an apparatus to launch and monitor laser-driven flyer-plates was developed. This was coupled to a home built photonic Doppler velocimeter (PDV) which tracks the motion of …

Investigations on detonation shock dynamics
A detonation is a combustion-driven shock wave. Typically, a detonation will consist of an inert shock followed by a region of chemical reaction referred to as the reaction zone. Detonations have a wide variety of engineering applications, from obvious military uses to explosive welding, hard rock …

Polymorphisms in heat shock protein receptors
Das extrazelluläre Hitzeschockprotein 70 (Heat Shock Protein 70, HSP70) kann als immunologisches Gefahrensignal fungieren und stimuliert die Aktivität zytotoxischer T-Lymphozyten und natürlicher Killerzellen. In diesem Kontext stellt HSP70 ein vielversprechendes Werkzeug im Rahmen immunologischer …
