1. Human growth hormone was prepared from acetone-dried residues after extraction of gonadotrophins from pituitary glands. 2. Crude growth hormone was purified by gel filtration on Sephadex, resulting in a product that is soluble in water or 0.5% sodium chloride. It is painless on injection and shows a twofold increase in biological potency. Aggregation of growth hormone on Sephadex columns can...

Significant research efforts have been devoted in recent years to the development of displacement-based seismic design methodologies, recognizing the shortcomings of traditional, code-specified force-based design procedures. Recent advances in direct displacement-based seismic design of columns rely on the estimates of yield curvature for the determination of seismic design forces to satisfy th...

In this study, the effect of soil structure under saturated and unsaturated flow conditions on nonreactive bromide (BR) transport was investigated. The soil structure treatments consisted of undisturbed columns (prismatic and granular structures), and disturbed columns (single- grain structure). A constant concentration (C0= 0.005 M) of bromide was supplied on the surface of the columns in a st...
