We solve the variational problem of determining the power of additional three-dimensional and surface heat sources to guarantee the minimization of the displacement field at the end of a finite circular cylinder on which a stationary heat flow is pre

The reaction conformations of the metastable molecular ions of the 3-hydroxy steroids were characterized using translational energy (T50%) release values and the ratios of metastable-ion peak heights to those of the main beams determined for the M+·

The individual steps of the consecutive reactions arising from metastable molecular ions, derived from vitamin D3, vitamin D2 and their respective provitamins (7-dehydrocholesterol, ergosterol), were examined in different field-free regions of a trip

The mechanism of water elimination from metastable molecular and [M − CH3˙]+ ions, as well as from ions deprived of ring D, in epimeric 3-hydroxy steroids of the 5β-series has been elucidated by deuterium labelling, by the measurements of the tra

The mass spectra of α-, β- and γ-pyridine aldoximes and the respective O-methyl ethers were studied. The mass spectral behaviour of α-pyridine aldoxime is characterized by the elimination of NO, while the molecular ion of the γ-isomer expels H2

The molecular ion of the N-methyl ortho-nitro-para-toluidine (I) readily eliminates H3O. The sources of the H atoms lost were proved by deuterium labeling to be an HNCH3 group as well as, probably, the C-methyl group of the aromatic ring. The interac
