Subject field(s)
  • Computer Programs and Programming

All of the primary TRACE operands establish trace traps. A trace trap is a programming function that, as its name implies, captures information about an event in your virtual machine.

Record 4 2011-03-09

English

Subject field(s)
  • Acoustics (Physics)
DEF

The frequency at which a sound wave incident upon a surface has a projected wavelength equal to the length of the bending wave excited in the surface material. The effect of this "trace matching" is a marked reduction in the sound transmission loss in the frequency region in which this occurs. The frequency is a function of the angle at which the sound impinges on the surface, the surface weight, and bending stiffness of the surface.

French

Domaine(s)
  • Acoustique (Physique)
CONT

Les pertes de transmission du son par les cloisons et les planchers dépendent également de la rigidité. Les courbes des pertes de transmission de son pour les matériaux rigides présentent des creux à certaines fréquences par rapport aux pertes calculées selon la loi de masse. Cet effet dit de coïncidence entraîne souvent un ITS plus faible. Les matériaux peu rigides comme les feuilles de plomb n'ont pas de creux de coïncidence. Les fréquences de coïncidence des différents matériaux se produisent dans diverses parties du spectre acoustique, parfois en dehors de la gamme normale utilisée en acoustique du bâtiment.

Subject field(s)
  • Biochemistry
CONT

The quantitative aspects of elemental electrospray mass spectrometry are investigated with particular emphasis on the factors affecting the ability to establish linear calibration curves. It is shown that linear calibration curves can be obtained for trace elements if the analyte signal is ratioed to the signal from a constant amount of a similarly charged electrolyte species. Linear calibration curves can be established over a concentration dynamic range of at least 4 orders of magnitude. The added component seems to function as a stabilizer and monitor of the electrospray process and as an internal standard. In certain cases species generated by acidification of the solvent may be used as electrospray stabilizers.

  • Biochimie
CONT

L'électronébulisation, connue sous le nom d'electrospray (ES), génère des ions multichargés , et permet l'utilisation d'analyseurs conventionnels peu onéreux comme les quadripôles. En effet, comme ce sont les rapports masse/charge qui sont mesurés par cette méthode, une protéine de masse 100 000 peut donner des ions 100 fois chargés apparaissant sur le spectre de masse au rapport masse/charge 1000.

Record 7 1998-05-14

Subject field(s)
  • Analytical Chemistry
CONT

In 1956, Harley and Pretorius described a simple discharge detector for gas chromatography based on the electrical properties of a glow discharge, the voltage across the gaseous discharge being a function of the type of gas present. Druyvesteyn and Penning in 1940 reviewed the complex nature of the glow discharge, noting that the discharge is maintained by electrons emitted from the cathode which result from processes related to positive ion bombardment, photoelectric emission, and collisions with excited atoms. When trace quantities of a material eluted from a chromatographic column enter the detector(consisting of a small platinum disk cathode and a tungsten wire anode), a voltage change resulted which was recorded.

OBS

Using neon lamps Pitkethly found ... that these detector were current and pressure independent at 1-1.5 mS and 3-5 mm Hg .... In 1958, Roberts and Hinkle evaluated glow discharge tubes as detectors for compounds in the concentration range of 5-500 ppm and concluded that the detector was not applicable to general-purpose use .... More recently, Wilhite described glow discharge-type devices which act electrically similar to a gas-filled voltage-regulator tube ... Riley described the use of an argon purity meter, a glow-type discharge detector, for the determination of small concentrations (0-1500 ppm) of impurity gases in argon.
