Awell defined sample of 72 Gigahertz Peaked Spectrum radio sources is compiled, having turnover frequencies in the range of 0.5 – 10 GHz. Using this sample, the canonical GPS radio spectrum is constructed, which is found to have a constant shape, independent of AGN type, redshift or radio luminosity. A possible deficiency of low turnover frequencies at high redshift is found, which may reflect ...

A method for the estimation of serum trypsin inhibitory capacity (TIC) was developed to permit consistent results with various trypsin sources without further standardization. Very small volumes of serum are used and the results are expressed in international enzyme units. Normal women show a slightly higher mean value for TIC than normal men. Sixty-seven patients with pulmonary emphysema were ...
