The efficiency of different balcony forms for reducing exterior noise was determined using a 1 50 scale model and a single spark source.
In this preliminary study the feasibility of a modified spark source was investigated as a method of rapidly dissolving solid conductive samples in aqueous media prior to analysis by atomic spectroscopy.
In the vacuum spark source, a pulsed, high-frequency potential of about 50 kilovolts is built up between two electrodes until electrical breakdown occurs.
The spark source, originally designed for spark emission spectroscopy in air, was modified by the installation of a spark ablation vessel.
The principal merit of the vacuum spark source is its ability to produce copious quantities of ions of all elements present in the electrodes.
BDD plates were characterized by spark source mass spectrometry, X-ray topography, X-ray diffraction, and Raman scattering.
The party needs a spark, a fire, a source of inspiration.
SAN DIEGO — The Mets' search for a source of comfort, a spark to lighten their mood as a dreary season enters its dog days, may be as simple as writing Johan Santana's name on the lineup card.
The concept of a minimum ignition energy (MIE), obtained using a capacitive spark discharge ignition source, has traditionally formed the basis for determining the hazard posed by fuels.
