TL;DR: In this paper, the velocity of ultrasound between two field points inside the volume of interest is calculated from measurements of differences in transit times of sound beams scattered in substantially opposite directions at these field points.
Abstract: Temperature inside a tissue volume is noninvasively determined on the basis of its known relationship with the velocity of ultrasound inside the volume. The velocity of ultrasound between two field points inside the volume of interest is calculated from measurements of differences in transit times of sound beams scattered in substantially opposite directions at these field points.

TL;DR: This NMR technique also demonstrated the primary isomeric positioning (>97%) of the butyrl group without the need for altering or fractionating the fat mixture.
Abstract: The amount of butyrate contained in a complex mixture of butter oil triglycerides was 10.3 mole % as determined by natural abundance13C Fourier transform pulse nuclear magnetic resonance (NMR) spectroscopy. This NMR technique also demonstrated the primary isomeric positioning (>97%) of the butyrl group without the need for altering or fractionating the fat mixture.

TL;DR: In this paper, the experimental results, together with some published data on the thickness of LPE layers of GaAs and GaAsxSb1-x grown by the horizontal technique, are consistent with the relationship T = bαt3]2+c, where b and c are constants.

04 Apr 1986TL;DR: In this article, a sputter coating source has separate annular targets spaced outwardly from each other around a central axis, and magnetic field generating means are provided to establish magnetic field lines over each target around an annular path.
Abstract: A sputter coating source has separate annular targets spaced outwardly from each other around a central axis. Magnetic field generating means are provided to establish magnetic field lines over each target around an annular path. Each target has its own separate magnetic field generating means including an electromagnet having a separately controllable power supply whereby the strength of the magnetic field over each target may be separately controlled. The targets are electrically separated from each other, and each target has a separately controllable power supply whereby the plasma power for each target may be separately controlled. More than two separate targets may be employed, and the various targets may be positioned at different distances from the substrate. The targets may be made of magnetic material.

08 Jun 1984TL;DR: A counterflow helium mass spectrometer leak detector is described in this paper, which includes a test port for receiving a gas sample including tracer gas helium, a high vacuum pump such as a diffusion pump and a mass analyzer tuned to detect the helium.
Abstract: A counterflow helium mass spectrometer leak detector includes a test port for receiving a gas sample including the tracer gas helium, a high vacuum pump such as a diffusion pump and a mass spectrometer tuned to detect the helium. The mass spectrometer is coupled to the inlet of the high vacuum pump. The leak detector further includes a cold trap containing liquid nitrogen coupled between the test port and the foreline, or outlet port, of the high vacuum pump. The helium received at the test port passes in reverse, or counterflow, direction through the high vacuum pump to the mass spectrometer. One or more mechanical vacuum pumps insure that the pressure at the foreline of the high vacuum pump is maintained at a prescribed level during a leak test. The cold trap condenses contaminants, water vapor and other gases from the gas sample and prevents backstreaming of oil from mechanical vacuum pumps.
