considerations on the explosion resistant design of special infrastructures have increased in the recent years. amongst the various types of infrastructures, road and railway tunnels have a unique importance due to their vital role in connection routes in emergency conditions. in this study, the explosion effects of a projectile impacting on a railway tunnel located in a jointed rock medium has...
PURPOSE We investigated the clinical and physiological effect of low intensity extracorporeal shock wave therapy on men with organic erectile dysfunction who are phosphodiesterase type 5 inhibitor responders. MATERIALS AND METHODS After a 1-month phosphodiesterase type 5 inhibitor washout period, 67 men were randomized in a 2:1 ratio to receive 12 sessions of low intensity extracorporeal shoc...
ub lis he d by M an ey P ub lis hi ng ( c) IO M C om m un ic at io ns L td A methodology developed to estimate with accuracy the instantaneous specific rock energy using corrected downthe-hole (DTH) drill monitoring data is presented. A specific rock energy profile can be generated for every hole, and thus a drilling site can be mapped for this index. A special data acquisition system was devel...
We describe the use of the continuous wave oesophageal Doppler monitor (ODM II) in the perioperative management of a patient with chronic obstructive coronary artery disease undergoing transmyocardial revascularization (TMR). The use of ODM II allowed both quantitative and qualitative assessment of cardiac function relatively noninvasively. It detected the successful transmyocardial penetration...
The current response of a d-wave superconductor containing a single impurity is calculated and shown to be singular in the low-temperature limit, leading in the case of strong scattering to a 1/T term in the penetration depth lambda(T) similar to that induced by Andreev surface bound states. For a small number of such impurities, we argue this low-T upturn could be observable in cuprate superco...
(1) Na wire [2] The single-row sodium nanowires exhibit conductance oscillation and bunching of high electron density with two atom-lengths in the channel density distribution. The relationship between the period of the conductance oscillation and the length of the bunches is interpreted using a simplified model. The difference in the penetration parameters between the incident Bloch wave and t...
We report a direct observation of space charge waves in photorefractive crystals with point group 23 (sillenites) based on their penetration into an area with uniform light illumination. It is shown experimentally that the quality factor of the waves increases substantially with respect to what current theory predicts [B. Sturman et al., Appl. Phys. A 55, 235 (1992)]. This results in the appear...
In this paper a novel approach for analyzing penetration of electromagnetic radiations in human tissue at different frequency is presented. Moreover, we concentrated our work on analyzing the other related factors describing system performance like return loss& Voltage Standing Wave Ratio (VSWR). consider We use different communication frequencies to simulate antenna for analyzing variation in ...
