The pedestal provides the boundary conditions for the hot core tokamak region and determines the stability properties of the plasma edge. The structure of H-mode pedestal depends on many factors such as heating of the plasma core, neutral fueling, recycling and density and thermal transport. It is important

The samples contained Ca2+, Mg2+ and Na+ as the dominant cations and HCO3- and Cl- were the dominant anions. Ratios of major cations and anions of water samples suggest the predominance of Ca and Mg-containing minerals over Na-containing minerals. According to TDS and SAR values, all samples were classed as 'freshwater' and 'excellent' categories. The SSP of all waters was under 'excellent' and 'good' classes. All samples were within 'soft' class regarding hardness with 'suitable' RSC. Based on As3+, Zn2+, Mn2+, Fe3+, SO42-, NO3- and Cl- all groundwater samples were within the 'safe' limit for drinking but unsuitable for some industries for specific ions.

Several reports have demonstrated that the lungs are the most important site of conversion of angiotensin I to angiotensin II. The purpose of the present study was to assess the extent of extra‐pulmonary conversion in man, during cardiopulmonary bypass. Plasma concentrations of angiotensin I and immunoreactive angiotensin II, and plasma renin activity were simultaneously determined, using specific radioimmunoassays, during extra‐corporeal circulation in 13 patients undergoing major cardiac surgery. Generally the renin‐angiotensin system was stimulated during cardiopulmonary bypass with maximum values occurring at different time. A highly significant correlation was found between plasma renin activity and angiotensin I and II concentrations respectively, as well as between these two peptides. Positive correlations were also obtained between arterial and venous samples for plasma renin activity and angiotensin I and II. Thus the presence of angiotensin II in plasma in the absence of pulmonary circulation and its parallel variations with plasma renin activity indicate that converting activity by extra‐pulmonary sources is not negligible.
