abstract  introduction: hypertension is a very common cardiovascular disease with extensive effects on body organs. this study was conducted to compare the extent of target organ damage in hypertensive patients with and without significant nocturnal fall in blood pressure (dippers and non-dippers, respectively). methods: one-hundred patients with recently diagnosed hypertension underwent 24-hou...

-A linear perturbation method is used to examine the stability of a unidirectional solidification problem in which a liquid, initially at the melting temperature, becomes solidified by heat transfer across a pressure-dependent thermal contact resistance to a plane mold. The contact pressure will be influenced by thermal distortion in response to the instantaneous temperature field in the solidi...

For high-temperature ultrasonic transducers piezoelement-to-metal thermosonic bonding technology was developed based on goldto-gold diffusion. Bond quality strongly depends on bonding parameters – pressure, temperature, ultrasonic power and time. The first step for achieving good bonds was ultrasonic monitoring of the process. In ultrasonic transducers good diffusion bond means good acoustic co...

− This paper proposes a low-cost technique to compensate for the temperature dependence of piezoresistive pressure sensors configured in a Wheatstone bridge. The sensor is treated as a resistive circuit and three equivalent resistances are measured by setting appropriately the bridge terminals. One of these equivalent resistances depends on temperature but not on pressure and, hence, it can be ...

Background: Arterial pressure is one of the most important physiological variables and often needs to be monitored repeatedly or continuously in perioperative period. Arterial pressure monitoring is one of the standard monitoring in operating room. During general anesthesia, blood pressure can be measured by using a noninvasive arterial pressure method or continuous invasive arterial pressure b...
