Using an explant culture system, we have demonstrated that human somatotropes respond to growth hormone releasing factor (GRF) and somatostatin (SRIF) from as early as 9.5 weeks of fetal age. Responsiveness to GRF increases significantly as a functio

The performance of a surface electric field strength meter, utilizing a broad unfocused beam of electrons, has been evaluated analytically and experimentally. The meter is capable of measuring E fields up to 100 V/cm and possesses a sensitivity of

A contact‐ionization source is described which generates a cesium ion stream characterized by a high degree of order in the ion motion. Electrons are added to form a quiescent, collisionless plasma stream. Diagnostic instruments are described for d
