CURRENT-METER OBSERVATIONS IN THE THAMES. (INCLUDING PLATE).

Plate Flatness Meter Based on Moire Fringes

A plate flatness meter based on the laser moire method was developed. A large grating is installed above a plate transfer line, a laser beam is directed through a concave lens onto the plate on the transfer line. Moire fringes that conform to the surface profile of the plate are formed on the plate. The flatness of the plate as i t is transferred can be measured to a high accuracy of +l. ODD( 2...

New Observations on the Mammalian Growth Plate

Chondrocytes at the lower zone of the growth plate must be eliminated to facilitate longitudinal growth; this is generally assumed to involve apoptosis. We attempted to provide definitive electron-microscopic evidence of apoptosis in chondrocytes of physes and chondroepiphyses in the rabbit. We were, however, unable to find a single chondrocyte with the ultrastructure of ‘classical’ apoptosis i...

Water Velocity Measurements in Open Channels Using Volumetric Current Meter (VCM)

An innovative Volumetric Current Meter (VCM) was designed in order to allow quick velocity measurements in open channels. At first, the coefficient of velocity (Cv) of the device was determined through calibration under different water velocities in the laboratory. The measurement performance was verified by measurements performed in similar flows in irrigation channels using an ordinary curren...

Histophysiology' provided a concise and entertaining guide to the puzzles of this strange nucleus. Currently I am focused on the thalamus and sensory mechanisms; Lord Adrian's short book 'The Basis of Sensation' on sensory mechanisms, published in 1928, says nothing about the thalamus, but is a wonderful example of clear thought about, and a lucid presentation of, a difficult subject. What is t...
