Isotope shifts, spins, hyperfine structures and masses have been measured for the series of the alkali isotopes including the nuclei far from stability. The method of laser spectroscopy and its combinations with rf excitation are described. Some results are discussed, namely the first observation of the red doublet D~-D2 of francium, and the study of shell effects and changes of shape with mass...

This report documents 2 cases of branchioblastomas in koi carp (Cyprinus carpio). Macroscopically, both cases were characterized by well-demarcated, pale red nodular masses located at the left first branchial arch and the right pseudobranch, respectively. Histologically, the neoplasias were composed of blast-like cells that differentiated into cartilage and branchial lamellae embedded in abunda...

allochthonous masses are common structures in zagros fold-thrust belt. they are generally considered as collapse structures formed by the influence of gravity and in rock units with competency contrast. however, large allochthonous masses mapped in dowgonbadan area in dezful embayment near the mountain front fault (mff) of zagros show characteristics different from the belt common collapse stru...

We review some approaches to the quark-lepton mass problem. The ideas of mass-protection and approximate chiral flavour symmetries as a framework for resolving the mass hierarchy problem are presented. Dy-namical calculations of the top quark and Higgs particle masses, based on infra-red fixed points and the so-called multiple point principle respectively, are discussed. We also consider mass m...

We calculate corrections to masses of massive neutrino mass–eigenstates, caused by vacuum polarization in the strong Coulomb fields of daughter heavy nuclei in the K–shell electron capture decays (EC) and positron (β+) decays of highly ionized heavy ions, investigated experimentally at GSI in Darmstadt. Some applications of the obtained results are discussed. c © Electronic Journal of Theoretic...
