A system for the rapid screening of urines for the presence of bacteriuria has been devised using a Coulter Counter Model ZBI linked to a multichannel pulse-height analyser (Coulter "Channelyser") with computer analysis of the output. In a series of 215 urines containing growth of a single pathogen of more than 100 x 10(6)/l (greater than 100 000/ml) satisfactory level of sensitivity (99.1%) wa...

Radiation produced by low-voltage discharge in a gas containing deuterium was measured using a Geiger counter located within the apparatus. This radiation was found to consist of energetic particles that were produced only when the voltage was above a critical value. In addition, the emission was very sensitive to the presence of oxygen in the gas. In the presence of the required conditions, em...

Geiger-Nuttall law is the simplest relation in radioactive decay relating half-life and energy. Initially restricted to $\ensuremath{\alpha}$ of individual isotopes, generalizations unifying different isotopes modes under a single set constant coefficients were subsequently achieved. This motivates investigating what extent such are possible. We also examine whether there exists universal that ...
