The objective of the present study was to test a hypothesis that a high dietary salt intake potentiates a cold induced increase in blood pressure in normotensive men. Male subjects (n = 12) were given 7 g day-1 sodium chloride during the cold months of the year, divided in 3-4 doses per day and dissolved in water, for 14 days additional to their normal diet which contained on the average 9.7 g ...

Several experiments involving two-dimensional and axisymmetric bodies have been carried out in a Trisonic wind tunnel at supersonic speeds to investigate and analyse the measured values of base pressure and to compare them with those from the theoretical methods. The objective of the experiments was to obtain an appropriate method for processing the results of wind tunnel tests on rockets or ai...

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...

  Abstract   Background: The pathophysiology of carpal tunnel syndrome is associated with   increased intracarpal canal pressure. Recently, palmaris longus has been introduced   as an independent risk factor for the development of carpal tunnel syndrome. The   purpose of this study was to assess the association of carpal tunnel syndrome with   the presence of palmaris longus tendon and function...

Surface-Piercing Propellers (SPPs) have been widely used in high speed craft due to some desirable features such as high efficiency, omission of resistance of equipment attached to the propeller and proper functioning of cavitation. Unlike the submerged propellers, theoretical methods have no significant application on simulation of SPPsbecause of problems related to modeling of these propeller...

Earthquake and its catastrophic failures has been one of the disturbance worry of Civil Engineers. In geotechnical science, liquefaction is one of the most important phenomenons induced by earthquake. A change in pore water pressure follows a change in effective stress, and in a critical state in which pore water pressure equals the total stress in soil particles, soil strength is suddenly lost...

An experimental study has been conducted to investigate the static and wind-on performance of two in-house-developed polymer-based pressure-sensitive paints. Platinum tetrakis (pentafluorophenyl) porphyrin and tris-bathophenanthroline ruthenium II are used as the luminophores of these two polymer-based pressure-sensitive paints. The pressure and temperature sensitivity and the photo-degradation...

The results of computational and experimental studies a model hypersonic convergent air intake are presented. Experimental were carried out in hot-shot wind tunnel IT-302M SB RAS at Mach number M = 5.7 an angle attack α 4 °. Numerical modeling was three-dimensional setting the ANSYS Fluent software package. calculations versions using different turbulence models: k- ɛ standard, RNG ɛ, ɷ standar...
