experiments were conducted to evaluate the performance of a low heat rejection (lhr) diesel engine. performance parameters and emission levels were determined at various magnitudes of brake mean effective pressure. combustion characteristics of the engine were measured with tdc (top dead centre) encoder, pressure transducer, console and special pressure-crank angle software package at peak load...

INTRODUCTION AND OBJECTIVES The study examined the effects of treadmill walking with load carriage on derived measures of central pressure and augmentation index in young healthy subjects. METHODOLOGY Fourteen male subjects (age 31.0 ± 1.0 years) volunteered in this study. Subjects walked 10 minutes on a treadmill at a speed of 5 km/h carrying no load during one session and a load of 10% of t...

[Purpose] The purpose of this study was to investigate the changes in muscle activation of the trunk and lower extremities and plantar foot pressure due to backpack loads of 0, 10, 15, and 20% of body weight during level walking in individuals with flatfoot. [Methods] Fourteen young flatfoot subjects and 12 normal foot subjects participated in this study. In each session, the subjects were assi...

Vortex extrusion (VE) is a severe plastic deformation technique which is based on the synergies between high strain accumulation and high hydrostatic pressure. Such a high amount of pressure, places a mandate to seek the method for investigation of the load under processing conditions. For this, kinematically admissible velocity field and upper bound terms based on Bezier formulation are develo...

BACKGROUND It is generally accepted that physical training decreases blood pressure in hypertensive subjects, but the importance of training intensity has not been established. This study compared the effects of endurance training at different intensities on ambulatory blood pressure and on blood pressure load (percentage of readings above 140/90 and 120/80 mm Hg during the waking and sleeping ...

It is proposed to use a single base platform in the Persian Gulf considering its low depth and more appropriate environmental conditions in comparison to North Sea and Mexico Gulf where this kind of platform is very popular. The pile of platform is responsible for transmission of environmental loads resulted from waves, currents, wind and dead loads to foundation of platform. Using SACS 5.3 sof...

investigating pressure applied in surface vertically that is done by use of mechanical procedures isn’t efficient to measure pressure applied in inner surface of reservoir or pipes having gas due to entering pressure into whole walls and different surfaces. So, in order to measure this kind of pressure, several studies were conducted in past decades and also various procedures were proposed tha...

Background. This study tested whether the simple ratio of ventricular end-systolic pressure to stroke volume, known as the effective arterial elastance (Ea), provides a valid measure of arterial load in humans with normal and aged hypertensive vasculatures. Methods and Results. Ventricular pressure-volume and invasive aortic pressure and flow were simultaneously determined in 10 subjects (four ...
