روش های مختلفی برای درمان چاقی موضعی و سلولیت وجود دارد که شامل روش های تهاجمی و غیرتهاجمی هستند. به دلیل عوارض جانبی بسیار کمتر، تمایل به استفاده از درمان های غیرتهاجمی رو به افزایش است. یکی از این درمان های رایج، درمان با امواج آکوستیک (acoustic wave therapy) یا shock wave therapy (swt) است. swt علاوه بر درمان سلولیت، در مواردی دیگری نیز مفید شناخته شده است. در این مقاله، ما ضمن معرفی اجمالی ...
Shock wave treatment accelerates impaired wound healing in diverse clinical situations. However, the mechanisms underlying the beneficial effects of shock waves have not yet been fully revealed. Because cell proliferation is a major requirement in the wound healing cascade, we used in vitro studies and an in vivo wound healing model to study whether shock wave treatment influences proliferation...
Flow visualisation of a normal shock impinging over a rounded contour bump in a Mach 1.3 free-stream
ABSTRACT An experimental study has been conducted to visualise the instantaneous streamwise and spanwise flow patterns of a normal shock wave impinging over a rounded contour bump in a Mach 1.3 free-stream. A quartz-made transparent shock generator was used, so that instantaneous images could be captured during the oil-flow visualisation experiments. Fluorescent oil with three different colours...
We report results of molecular dynamics simulation of shock wave propagation in silicon in [100], [110], and [111] directions obtained using a classical environment-dependent interatomic potential (EDIP). Several regimes of materials response are classified as a function of shock wave intensity using the calculated shock Hugoniot. Shock wave structure in [100] and [111] directions exhibit usual...
A weak-shock solution is obtained for the nonlinear propagation of a waveform that initially has the form of an asymmetric double exponential. Such a wave shocks at its peak, so that shock growth and wave-amplitude attenuation occur simultaneously. Simple formulas for wave amplitude, shock amplitude, and arrival time are given as is an expression for the waveform. We also present a general tech...
The effects arising from accelerated and decelerated motion of a point charge inside a medium are studied. The motion is manifestly relativistic and may be produced by a constant uniform electric field. It is shown that in addition to the bremsstrahlung and Cherenkov shock waves, the electromagnetic shock wave arises when the charge particle velocity coincides with the light velocity in the med...
OBJECTIVE To explore the effect of low-energy extracorporeal shock wave therapy to improve myocardial micro-vascular circulation after acute myocardial infarction at the early stage in pig model. METHODS A total of 25 domestic pigs were used in this study. Model of acute myocardial infarction (AMI) was created successfully by the implantation of angioplasty balloon in mid-distal segment of le...
In this thesis, I study propagation of gravitons in the shock wave geometry in the context of the AdS/CFT correspondence, with the goal to uncover some constraint on the supergravity action in the AdS space. In studying the shock wave geometry in an anti-deSitter (AdS) space, I find that the functional form of the shock wave metric does not receive a' correction, but the wave profile does. Then...
The end plate mounted at the mouth of the shock tube is a versatile and effective implement to control and mitigate the end effects. We have performed a series of measurements of incident shock wave velocities and overpressures followed by quantification of impulse values (integral of pressure in time domain) for four different end plate configurations (0.625, 2, 4 inches, and an open end). Sho...
