Tuning Stubs as an Aid to Coupling RF Energy to Electrodeless Discharge Lampsncorrect coupling of the rf energy (via the usual coaxial transmission line) occurs, several undesirable conditions result: (1) The energy transfer is inefficient and the coaxial transmission line will dissipate some of the energy as heat, and (2) some of the rf energy will be reflected back to the

A Simple Modification of a Flame Photometer for Routine Trace Potassium Analysisnalysis in this concentration range.. In fact, since K is not as ubiquitous as Na, precautions to avoid spurious contamination of samples should not need to be as stringent. However, conventional flame photometers are generally less sensitive at the detection wave length of 766.5 nm for K. Good phot

Prevention of Laser Microprobe Staining of Analyzed Metalsmple closely adjacent areas is thereby nullified. Deposition of the stain can be restricted to the dimensions of a central hole in a paper shield; however, placement of a shield is difficult even for plane surface samples.

Instead, we focus on its implications on universal scaling and illustrate the main results, e.g. by sketching how renormalisation-group theory allows one to identify the releva

M. S. Wangcally, far-from-equilibrium systems often display - namical scaling, even if the stationary state isvery far from being critical. A 1 As an example of a non-equilibrium phase transition, with striking practical c- sequences, consider the allotropic change of metallic ?-tin to brittle ?-tin. At o equ
