Apparatus tests flammability and ignition characteristics of materials in close proximity to incandescent metal fragments or spalls ejected from intermittent short circuit arcs in air or oxygen rich atmospheres. It simulates a situation where an exposed live wire makes contact with a grounded member in areas containing organic matter.
Mass spectra of quinoline and isoquinoline N- oxides, discussing diagnostic values of fragmentation reactions for heteroaromatic N- oxide function presence
Mass spectral fragmentation of substituted aliphatic glycols and hydroxylated carbon-carbon bond
Primitive solar nebula physical model considered under angular momentum conservation in collapsing fragment
Centrifugation for removal of bullet fragment floating freely in ventricular system of human brain to fixed safe position in left lateral ventricle wall
Photoionization source with a vacuum UV monochromator is used in ion reaction kinetics. Monochromator passes only the photon energies near the threshold of the selected ionization process. Absence of electron impact alleviates creation of different type ions that result in ion fragmentation.
Icarus asteroidal nature and fragmentation origin suggested from inclusion in angular momentum density-mass diagram
PreHayashi phase of stellar evolution, discussing protostellar disks /stellisks/ formation from flattened fragments of collapsed interstellar cloud under turbulent viscosity
Surveyor 7 alpha scattering experiment and TV image data revealing lunar surface chemical composition, rocks and fragments, etc
Magnetothermal instability and radiative effects on incipient fragmentation of rotating gravitating interstellar fluid forming condensations
Cyclohexene oxide mass spectral fragmentation by means of deuterium labeled analogs
Centrifuging as therapeutic device tested on male assault victim with bullet fragment floating freely in brain ventricular system
Computerized analysis of shear failure at initial fragment collision during trifragment rotor disk interaction with containment rings
Oxadiazolone pyrolytic and photolytic fragmentation, noting intramolecular cyclizations and intermediate azomethine nitrene production
Crew radiation dosage from fission fragments in plume from gas core nuclear rocket
Very heavy primary cosmic ray particles propagation calculation, using fragmentation parameters
Surveyor program results, discussing lunar craters, rock fragments, particle size optical, thermal and radar characteristics and chemical composition
Opaque minerals in Apollo 11 lunar igneous and fragmental rocks, using reflecting microscope and electron microprobe
