Single-unit carotid sinus baroreceptor activity was recorded in normal and heart-failure (pacing-induced) dogs. The sensitivity of these units was compared between the two groups of dogs. After development of clinical heart failure, the animals were anesthetized, and the left carotid sinus was vascularly isolated and perfused with oxygenated Krebs-Henseleit solution. Single-unit baroreceptor di...

Positive and negative polarity fast ionization wave discharges in nitrogen and dry air are studied in a rectangular geometry channel over a wide range of time delays between the discharge pulses, s = 10 ms to 25 ls (pulse repetition rates of m = 100 Hz– 40 kHz). The discharge is generated by alternating polarity high-voltage pulses (peak voltage 18–23 kV, pulse duration 50–60 ns). Ionization wa...

(pacing-induced) dogs. The sensitivity of these units was compared between the two groups of dogs. After development of clinical heart failure, the animals were anesthetized, and the left carotid sinus was vascularly isolated and perfused with oxygenated Krebs-Henseleit solution. Single-unit baroreceptor discharge was recorded from the carotid sinus nerve in response to stepwise increases in ca...

In this paper, we report the synthesis of tin oxide (SnO2) nanoparticles by co-precipitation technique. The structural, surface morphology, thermal and optical properties of the SnO2 samples were analysed using X-ray diffraction (XRD), High-resolution transmission electron microscopy (HRTEM), Fourier transformed infrared (FTIR) spectrum, thermo gravimetric analysis (TGA/DT...

First, a globally-averaged RF plasma model is used to investigate exit conditions immediately following a RF pre-ionization stage. Analysis shows that reducing pulse duration from 10 to 10 seconds increases peak ion energy fraction by 17% (from 16 to 33%) and doubles final conductivity. Pulse waveforms are square in nature, and ion energy fraction is defined in this work as the percentage of to...

Titanium nitride (Ti-N) thin films are electrically and thermally conductive have high hardness corrosion resistance. Dense defect-free Ti-N been widely used in the surface modification of cutting tools, wear resistance components, medical implantation devices, microelectronics. In this study, were deposited by power pulsed magnetron sputtering (HPPMS) their plasma characteristics analyzed. The...

In this paper the perturbation approach is used to investigate the analytical properties of the sensitivity to the initial conditions on the calibration and simulation results of two karst spring discharge reservoir models. The propagation of uncertainty in the initial conditions is shown to depend on both model structure and the values assumed by state variables at the beginning of simulation....
