Quantitative spore recoveries from diatomaceous earth pellets used to simulate electronic components in dry heat sterilization studies
Indium tipped probe measures hydrophobic and hydrophilic contaminants on rough and smooth surfaces. The force needed to pull the indium tip, which adheres to a clean surface, away from the surface provides a quantitative measure of cleanliness.
Quantitative analysis of liquid oxygen-liquid hydrogen combustion products using spectrometer
Purkinje cells discharge sequences analyzed quantitatively for anesthetized and nonanesthetized animals, discussing spontaneous and stimulated activity projected on cerebral cortex
Shock generated plasma boundary layers, discussing equilibrium ionization and quantitative schlieren technique
Electron precipitation into ionosphere and mesosphere in auroral zone studied for quantitative aspects from ground based and space observations
Method allows qualitative and quantitative analysis of mixtures of partially deuterated compounds. Nuclear magnetic resonance spectroscopy determines location and amount of deuterium in organic compounds but not fully deuterated compounds. Mass spectroscopy can detect fully deuterated species but not the location.
Photometric method based on the use of bacterial luminiscent reaction quantitatively detects the presence of flavin compounds in all forms of life. Aqueous cellular dispersion of a biological sample with an aqueous perchloric acid ruptures the cells and frees the flavin coenzymes from their proteins.
Quantitative microbial sampling requirements for Apollo modules
Developments in quantitative luminescence techniques
Application of theories for spectral line formation to quantitative interpretation of solar magnetograph readings
Earth surface temperature change quantitative determination due to Milankovitch insolation variations
Quantitative magnetic field models of magnetosphere for analyzing field configuration variations and adiabatic particle motion
Quantitative gas-liquid chromatography of sulfur amino acids trimethylsilyl derivatives
Quantitative analysis for N-acetylneuraminic acid by gas-liquid chromatography using trimethylsilyl derivative
Quantitative density data from schlieren measurements by photomultiplier technique for axisymmetric flow outside diffraction bands
Method quantitatively converts water vapor to carbon dioxide permitting direct and rapid analysis of mixed-gas streams for water content.
Quantitative interpretation of three dimensional weakly refractive phase objects using holographic interferometry, determining index of refraction
