RESUMO
The vertebrate fauna from the cave deposits in Imanai Cave in the Southern Urals (53°02' N, 56°26'E) has been studied. It contains 715 bones that belonged to at least 11 individuals of fossil lion (Panthera (Leo) ex gr. fossilis-spelaea). It has been established that this is one of the largest Eurasian burial sites of fossil lions. The bones were accumulated due to the natural death of animals inside the cave. The age and sex estimations have shown that at least six adult males and five adult females died there. According to the accompanying fauna, radiocarbon, geochemical, and mineralogical analyses and archaeological finds, the interval of the lion bone accumulation is determined as the first half to middle of Late Pleistocene (OIS 5-3).

Terminology and synonyms of comorbidity are discussed in much detail along with historical prerequisites of combined pathology, factors influencing its development and progression, and classifications of its variants. A review of advantages and drawbacks of the most popular models of comorbidity and methods of its evaluation based on standard scales is presented. Much attention is given to the structure of definitive diagnosis and principles of its formulation.

An accelerator-driven thermal neutron source for BNCT, planned to be installed at the INFN Laboratori Nazionali di Legnaro (LNL), is in progress in the framework of the SPES (selective production of exotic species) research program. The most critical element of such a facility is the construction of a reliable neutron converter based on the (9)Be(p,xn) nuclear reaction, working at a high power level (150 kW) and 5 MeV beam energy, due to the SPES driver constraints. Two original, beryllium-based, target concepts have been designed for such a purpose. The present status of the neutron converter, as well as the test results performed so far on prototypes constructed, is reported here.
