Walker Carcinoma 256*t

Dieta.—Male Wistar rats were placed on a semi synthetic diet at weaning, and the food consump tion of each was measured. A week later each rat was paired with one of equal body weight and food consumption. At this time one rat of each pair was designated as the experimental rat which would receive a tumor transplant; the other rat, his pair fed control, consumed the amount of diet eaten by th...

General Transformation Formulas for Fermi-Walker Coordinates

We calculate the transformation and inverse transformation, in the form of Taylor expansions, from arbitrary coordinates to Fermi-Walker coordinates in tubular neighborhoods of arbitrary timelike paths for general spacetimes. Explicit formulas for coefficients and the Jacobian matrix are given.

The EUV transient RE J 1255

We have identiied the optical counterpart of the EUV transient source RE J1255+266 with a 18 magnitude blue star which has an unusual optical spectrum showing a blue continuum and broad Balmer absorption lines characteristic of a DA white dwarf, together with intense narrow H Balmer and He I lines in emission. Subsequent optical spectroscopy and photometry, together with near-IR photometry, dem...
