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...

This study addresses the hypothesis that atrial natriuretic factor (ANF) is a primary vasodilator, which reduces arterial pressure directly and increases total peripheral resistance secondarily by reflex mechanisms. The effects of 30-minute infusions of ANF (0.3 micrograms/kg/min i.v.) were examined in conscious dogs, rats, and monkeys before and after ganglionic blockade with hexamethonium. In...

Electrical discharge machining process, is one of the most widely used methods for machining, the electrically conductive parts. In this way the tool is not in contact with the workpiece and the hardness of workpiece does not affect the machining speed. In Electrical Discharge Machining process, selection of the correct machining parameters are effective in final cost and the quality of the pro...

A thermoelectric generator was used to recover waste heat from a source, such as engine exhaust. The key elements of the are exchanger and module. Thermoelectric modules convert energy electrical using Seebeck effect. temperature difference between hot cold sides module is required generate electric power. theoretical model developed predict current, voltage, power output. bismuth Telluride for...

P ower training using different loads causes specific changes to the force–velocity relationship that creates variability in the degree to which power output is improved. Several investigations have indicated that training with the load that maximizes power output is more effective at improving maximal power production and athletic performance than either lighter or heavier loading conditions (...

BACKGROUND To determine the effect of adiposity in males aged 50-70 years on cardiovascular responses to acute psychological stress. METHODS Lean (BMI 20-25 kg/m(2)) (n = 21) and overweight/obese (BMI 27-35 kg/m(2)) (n = 21) men aged 50-70 years were subjected to psychological stress. Systolic blood pressure, diastolic blood pressure, heart rate, total peripheral resistance, and cardiac outpu...

Ninety-four patients with occasionally elevated (borderline) blood pressure, 61 patients with asymptomatic established hypertension, and 63 normal subjects have been studied at rest and during a progressive exercise test on a cycle ergometer. Subjects with borderline blood pressure had increased cardiac output in the resting recumbent position, but this was not maintained in the sitting positio...

A (k, l)-robust combiner for collision resistant hash functions is a construction, which takes l hash functions and combines them so that if at least k of the components are collision resistant, then so is the resulting combination. A black-box (k, l)-robust combiner is robust combiner, which takes its components as black-boxes. A trivial black-box combiner is concatenation of any (l−k+1) of th...
