Determination of resistance to cavitation of pyrophyllite samples
Zaštita Materijala, 2021 The resistance under the action of cavitation of sintered pyrophillite samples was investigated. The initial sample of pyrophillite from the Parsovic-BiH deposit was ground a vibrating mill to a granulation of 20 mm, pressed and sintered at temperatures (

Mass Loss from Cool Stars [PDF]
Annual Review of Astronomy and Astrophysics, 1981 AbstractRecently obtained spectroscopic observations indicating mass loss in cool stars are reviewed with analogies to the solar atmosphere. Spectral diagnostics of mass loss are discussed with new theoretical calculations of chromospheric line profiles.

Mass Loss from Eta Carinae [PDF]
Symposium - International Astronomical Union, 1979 This high luminosity (5 × 106 L⊙) star since 1840 is losing mass at the rate of 7.5 × 10−2 M⊙ per year. The large mass loss could be the result of vibrational instabilities produced in the CNO hydrogen burning phase of a very massive (160 M⊙) star. The presence of high excitation lines in the ultraviolet spectrum of Eta Car suggests the idea of a hot ...

Profiling Corrosion Rates for Offshore Wind Turbines with Depth in the North Sea
Energies, 2020 Corrosion in the marine environment is a complex and expensive form of damage. It is commonly studied by the deployment of coupons that reflect the marine corrosion a structure will experience, thus allowing design and maintenance prevention strategies ...

International Astronomical Union Colloquium, 1981 High dispersion spectrograms of α Ori are obtained. Several strong absorption lines which have circumstellar components are measured. Assuming the plane-parallel envelope and thermal equilibrium, the mass loss rate is estimated as 1x10-6 Mʘ/yr.To obtain the mass loss rate of red giant stars is very important in connection with the study of the stellar ...
