RESUMO
The gyromagnetic factor of the low-lying E=251.96(9) keV isomeric state of the nucleus ^{99}Zr was measured using the time-dependent perturbed angular distribution technique. This level is assigned a spin and parity of J^{π}=7/2^{+}, with a half-life of T_{1/2}=336(5) ns. The isomer was produced and spin aligned via the abrasion-fission of a ^{238}U primary beam at RIKEN RIBF. A magnetic moment |µ|=2.31(14)µ_{N} was deduced showing that this isomer is not single particle in nature. A comparison of the experimental values with interacting boson-fermion model IBFM-1 results shows that this state is strongly mixed with a main νd_{5/2} composition. Furthermore, it was found that monopole single-particle evolution changes significantly with the appearance of collective modes, likely due to type-II shell evolution.
RESUMO
Having studied the dynamics of stresses in models of scoliotic models of different types of surgical correction the authors have determined the optimal methods of treatment depending on the kind of deformation.

A questionnaire was prepared for the evaluation of the quality of life directed at assessment of the patient's attitude to changes that had taken place in his life due to his illness. Results of observations of 124 patients (94 with myocardial infarction and 30 with arterial hypertension) show the validity of the questionnaire and its discriminant possibility. Difference in the indices of quality of life has been established between the infarction and the hypertensive patients. In persons who retained working capacity and in patients used to physical exercise the overall index of quality of life was higher than invalids or patients who were not used to physical training. In persons with low overall index of quality of life MMPI, according to 1, 2, 7 and 8 scales, were statistically significantly higher than in persons with high overall index of quality of life. The method permits one not only to give a quantitative assessment of the quality of life as a whole, but also to take into consideration concrete reasons for its deterioration.
