In this study, some characteristics of a Mather type Plasma Focus (PF) device such as a discharge current, pinch time, ion flux and hard x-ray intensity has been investigated simultaneously in argon and nitrogen gases separately for various operating gas pressures and charging voltages of capacitor bank. It was observed that pinch phenomena was energy and pressure dependent in current sheath as...

In this paper the effect of composite hoop-wrapped on stress intensity factor for semi-elliptical external crack which located in spherical pressure vessel, were investigated through the Finite Element Analysis. In order to find the effect of some parameters such as composite thickness and width, internal pressure and crack geometry, comparisons between different cases were done and discussed i...

Background and Objectives: High blood pressure affects nearly 30% of adults. Inactivity and low intake of antioxidants are associated with increased risks of high blood pressure and cardiovascular diseases. High intensity interval exercise increases blood pressure and oxidative stress. The purpose of this study was to investigate effects of L-citrulline consumption on oxidative stress and antio...

conclusions our results indicate that changes in muscle thickness and echo intensity are induced by different inward pressures of the transducer during us. when using a technique that involves a handheld transducer, the examiner should attempt to maintain consistent inward pressure of the transducer during us, to quantify the minimal change of the rf mass and composition. results muscle thickne...

sound power is considered as an excellent measure for evaluating the efficiency of noise controls as well as for comparing noise sources in workrooms. this parameter can be determined by sound pressure or intensity based methods in real conditions of workrooms. this paper aims empirically to compare these in situ methods in relation to a typical industrial machine located in workroom in terms o...

The spontaneous electroluminescence emission of InAs light-emitting diodes ~LEDs! operating at 3.3 mm was studied as a function of applied hydrostatic pressure. An enhancement of a factor of almost four in radiative efficiency at room temperature was observed in the range 0 to 10 kbar. Analysis of the dependence of electroluminescence emission intensity on hydrostatic pressure at constant curre...

We examined on 56 (age 38+/-2 [range: 16-60] years) healthy subjects the effects of aging on cardiovascular autonomic responses to progressive supine bicycle exercise of light intensity. Autoregressive spectral analysis of RR interval and systolic arterial pressure (SAP) variabilities provided measures of the exercise-induced changes in baroreflex gain (by index alpha) and in sympathetic and va...

We studied experimentally the dependence of light emission and phase space boundaries of air bubbles in water on the level of degassing down to low partial pressures of 15 mmHg. We found that the maximum obtainable light intensity increased monotonically by lowering the concentration of dissolved air in water. We also present a new technique to obtain the acoustic pressure (P(a)) and ambient ra...
