Osmotic regulation of vasopressin and renin in spontaneously hypertensive rats.

 · 1970

Abnormalities in the vasopressin and renin systems have been reported in spontaneously hypertensive rats (SHR). Therefore, studies were performed to evaluate the responsiveness of these systems to cha…

Acoustics of a standing wave tank for studying the hearing capacity of fish.

 · 1970

In a standing wave tank responses of fish to sound stimuli used to investigate the hearing capacity of fish may perhaps be affected by unintended stimulation of the lateral line. Uniform oscillatory w…

Vesicles in haptotaxis with hydrodynamical dissipation.

 · 1970

We analyze the problem of vesicle migration in haptotaxis (a motion directed by an adhesion gradient), though most of the reasoning applies to chemotaxis as well as to a variety of driving forces. A b…
