A motion platform was developed that oscillates an animal in a foot-to-head direction (z-plane). The platform varies the frequency and intensity of acceleration, imparting periodic sinusoidal inertial forces (pG(z)) to the body. The aim of the study was to characterize ventilation produced by the noninvasive motion ventilator (NIMV) in animals with healthy and diseased lungs. Incremental increa...

Static characteristics of baroreceptors differ depending on whether receptors are connected to myelinated or unmyelinated axons (MBs and UBs) and whether they come from normotensive or spontaneously hypertensive rats (NTRs and SHRs). Dynamic characteristics are incompletely known and were examined using an in vitro rat aortic arch-aortic nerve preparation in which static characteristics are sim...

Kawasaki, S., Henderson, J.M., Hertzler, G. and Galloway, J.R. (1991) The role of continued drinking in loss of portal perfusion after distal splenorenal shunt. Gastroenterology; 100, 799-804 HPB INTERNATIONAL 71 Fifty percent of patients with alcoholic cirrhosis who undergo distal splenorenal shunting for variceal bleeding lose portal perfusion within 1 year. Although it was previously conside...

This paper proposed a semi-theoretical model to quantitatively predict leakage rate of tubing and casing premium connections. The geometric parameters the sealing surface profile approximated by sinusoidal micro-convex were first obtained based on random normal distribution sampling method. With actual area prediction formula for elastic–plastic contact an axisymmetric body equivalent simulatio...

This experimental study is devoted to the spectroscopic investigation of a pure xenon mono-filamentary dielectric barrier discharge (MF-DBD) operating with a sinusoidal voltage supply, at a frequency of ∼10kHz. The influence of gas pressure and gap distance on its radiation, emitted within 300 and 900nm, is analyzed in the range of 100 to 760Torr and 1 to 3mm. A particular interest is paid to t...

Wireless power transmission is based on electromagnetical phenomenon between two separate coils. In order to transfer power from one to the other, we have to cause a time-varying current along one coil. Many of conventional wireless power transmission systems suppose a sinusoidal current of the coil. One reason for it could be the convenience that we have a sinusoidal power source as the indust...

The equation is solved numerically for the constants: liquid density ρ = 0.998 kg/m, surface tension σ = 0.07275 N/m, viscosity μ = 0.001 Pa·s, vapor pressure (water) pv = 2.330 kPa, static pressure pstat = 100 kPa to 20 000 kPa, polytropic exponent γ = 1.67, sound velocity in the liquid C0 = 1482 m/s. The variables in the equation are the radius of the bubble R and time t, an overdot means the...

In this paper, the oscillometric waveform measured by automatic non-invasive blood pressure meters (NIBP) is analyzed by transforming the data from the time domain to the frequency domain. The signal’s spectrum of the oscillometric waveform is in current literature badly understood or explored. The only known link between the oscillometric waveform and the blood pressure is the maximum of the o...

This paper describes a simple method for the measurement of the effect of periodic stimuli on the frequency of crystal resonators. The technique has been implemented for the measurement of both acceleration and pressure sensitivity. The system is based around a passive method that has been previously used for residual phase noise measurement. In the case of acceleration sensitivity measurement,...
