Invar Beam Balance for the Study of Fast Chemical Reactions,beam balance 14.5 cm long and weighing 46 g was constructed using 2- and 3-mil tungsten wire supports to replace our conventional microbalance. The balance has a sensitivity of 0.4 to 0.8 · 10. g/div. The balance is read in the conventional manner at the end supports and 1 division equals 0.001 cm.

An Apparatus for the Simultaneous Measurement of the Optical Transmission and Mass Changes in Thin f the metal film is inferred from measurements carried out with an automated bakeable vacuum microbalance. The optical transmission of the film is measured for monochromatic light from 4000 to 8000 A. The experimental difficulties encountered in this study are discussed in detail..Results obtained w

Mass and Thermal Measurement With Resonating Crystalline Quartz, must be relied upon both to define or delineate the resonant frequency of the quartz plate and to maintain a known amplitude of vibration. Circuitry for use at 5 Mc is given..With edge-mounted quartz plates vibrating in the thickness shear mode, detection of mass changes in the range of 1 to 10 picograms seems feasible.

Jakub Szymaniktation of the heart rate to draw prognostic conclusions—somehow a modern rationale—that deserves further attention. The rapid advancement of science is providing more and more information about the details, but the subatomic resolution of structures hides the risk and the complex procedures are frag
