A class of three substances has been isolated in highly purified form and in substantially pure form by utilizing thymus tissue as a source material. These three substances are designated thymone A, thymone B and thymone ...

The chemical structure of the luteinizing hormone releasing hormone (LHRH) was elucidatd in 1971. Since then, a very large number of international investigators synthesized more than 100 monosubstituted and about 14 ...

Two sets of hormonal peptides are synthesized which are super agonists of the lutenizing hormone releasing hormone (LHRH). Chronic administration results in the inhibition of LHRH which is responsible for stimulating cell ...

For making rapid, non-destructive permeability measurements in the field, a portable minipermeameter of the kind having a manually-operated gas injection tip is provided with a microcomputer system which operates a flow ...

A power supply generating a reaction torque generally simultaneously with its power output is utilized to supply power to fire the railgun. The power supply and the railgun are cooperatively mounted together such that the ...

A high-energy, high-current homopolar generator pulsed power supply system that is compact and field portable. The power supply system includes a hompolar generator (HPG), an auxiliary supply and drive system, both mounted ...

Glassy-type gas separating membranes are conditioned to a state of enhanced permeability through controlled sorption of a selected conditioning gas such as CO.sub.2. Membranes are swelled to a state of plasticity without ...
