The theory of tokamak stability to nonlinear "ballooning" displacements of elliptical magnetic flux tubes is presented. Above a critical pressure profile the energy stored in the plasma may be lowered by finite (but not infinitesimal) displacements of such tubes (metastability). Above a higher pressure profile, the linear stability boundary, such tubes are linearly and nonlinearly unstable. The...

If we are using the Duocom, we initially compress to 18 msw with the intention of treating using a RN Table 62 profile of pressure and time. We have the option of going to 50 msw in deteriorating cases. On arrival in Townsville, the diver is transferred, under pressure, to the main chamber in the Hyperbaric Medicine Unit of the Townsville General Hospital (Figure 3), where the treatment profile...

The systolic blood pressure (SBP), diastolic blood pressure (DBP) and pulse pressure (PP) daily profiles incidence was studied in 53 patients with arterial hypertension. A significant difference in the frequency of occurrence of different types of SBP, DBP and PP daily profile was revealed. In the structure of SBP daily profile nondipper and dipper types were dominated, DBP dipper and overdippe...

This analysis investigates the distortion of flow measurement and the increase of cavitation along orifice flowmeter. The analysis using the numerical method (CFD) validated the distortion of flow measurement through the inlet velocity profile considering the convergence and grid dependency. Realizable k-e model was selected and y+ was about 50 in this numerical analysis. This analysis also est...

In low-pressure discharges, where the electron mean free path is larger or comparable with the discharge length, the electron dynamics is essentially nonlocal. Moreover, the electron energy distribution function (EEDF) deviates considerably from a Maxwellian. Therefore, an accurate kinetic description of the low-pressure discharges requires knowledge of the nonlocal conductivity operator and ca...

Four multiphase flow models or correlations (Duns & Ros, Hagedorn & Brown, Orkiszewski, and Beggs & Brill) are currently available in Hydra for predicting the pressure profile in a well. The range of applicability of the multiphase flow models is dependent on several factors such as, tubing size or diameter, oil gravity, gas-liquid ratio, and, two-phase flow with or without water-cut. The effec...
