High-Sensitivity Antitumor Drug Sensitivity Testing

Oncology, 2009
For antitumor drug sensitivity testing we have been performing the succinic dehydrogenase inhibition test using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphe-nyltetrazolium bromide (MTT). A new tetrazolium salt 2,3-bis(2-methoxy-4-nitro-5-sulfophenyl)-5-[(phenyl-amino) carbonyl]-2H-tetrazolium hydroxide (XTT) has been synthesized recently, and we have been ...

High‐order sensitivity invariants

International Journal of Circuit Theory and Applications, 2010
AbstractThe aim of the research reported in this paper is to extend the notion of invariant sensitivity sum, widely known for electrical networks, from first‐order sensitivities to high‐order sensitivities. The results are high‐order invariant sums of sensitivities of the first and the second kind, formulated for nonlinear lumped circuit, which ...

High-Frequency Sensitivity in Infants

Science, 1980
Auditory thresholds were determined for infants and adults to half-octave bands of noise centered at 10,000 and 19,000 hertz. Adults were significantly more sensitive than infants at 10,000 hertz, but at 19,000 hertz, adults and infants had comparable thresholds.

High Sensitivity

Physics Today, 1949
Wartime developments in radar have made available equipment for producing and detecting short radio waves of a few millimeters to centimeters in length so that it is now convenient and easy to study the absorption of various substances, particularly gases, in this region of the electromagnetic spectrum.

High sensitivity electrospray interface

2015
The invention provides a sheath-flow interface for producing electrospray from a capillary. The electrospray generated by the interface can be used as the source of ions for mass spectrometry. Electrokinetic flow in the interface can move a sheath liquid past the end of a capillary so as to mix with an analyte effluent discharged from the capillary ...

Micromanometer of High Sensitivity

Review of Scientific Instruments, 1956
A sensitive micromanometer based on the observation of the movement of a bubble of air in a precisionbore, horizontal capillary tube was constructed. The sensitivity was varied by connecting different-sized chambers which had nominal diameters of 1, 2, and 3 in. The sensitivity could be varied between 2×10−5 in. and 2×10−6 in. of manometer fluid.

High-sensitivity autoionography

Journal of Physics E: Scientific Instruments, 1978
Ionography can replace conventional film autoradiography in the detection of radioactive spots on thin-layer chromatograms. The sensitivity of autoionography has been greatly increased by the use of thick charge receptors instead of the thin imaging foils used hitherto, and also, for some radionuclides, by the use of higher gas pressure.

High sensitivity polarimetry

Astronomische Nachrichten, 2003
AbstractOver the last decade spectro‐polarimetry evolved to ever higher sensitivity levels. New techniques and instruments allow us to address weak polarization signals, which are caused by scattering in the solar atmosphere. In this paper a review on the development of spectro‐polarimetric investigations of scattering physics and its coupling to the ...

A high sensitivity polarimeter

Optics Communications, 1975
Abstract A photoelectric polarimeter is described which works by the synchronous detection of light signals modulated by a rotating polarizer. Experiments are performed which show how the instrument is suited for measuring both very faint fluxes of polarized light, and light with a small degree of polarization, i.e. up to 10-4.
