On theorems of minimum energy dissipation in magnetohydrodynamics
This paper is concerned with some theorems on the dissipation of energy in magnetohydrodynamics. It is shown that when certain conditions, (2.21) or (2.27) of the text, are satisfied, the steady motion of an e...

Capacity of Pepsin-digested Antibody to inhibit Antibody Formation
THE capacity of passively administered serum antibody to inhibit specific antibody formation1 has suggested that serum antibody may act as a type of “feedback” mechanism2–5. It is not known whether this effect of...

Radiation-induced Depression of Primary and Secondary Antibody Responses to Bacteriophage φX 174 in vitro
WHOLE body X-irradiation depresses or enhances the antibody response depending on the dosage and its temporal relationship to injection of antigen in the animal1. Using organ cultures of rabbit lymph nodes, we su...
