    Notes: Summary Fifty-five experimental (29 male, 25 female) and 38 control (20 male, 18 female) adolescent subjects participated in this study to investigate the differences in coronary heart disease (CHD) risk factors in groups of trained and untrained adolescents. As expected the trained group (both sexes) had higher maximal aerobic power $$(\dot V_{O_{2 max} } )$$ and lower systolic blood pressure at rest. The level of total cholesterol was the same in both groups, but the levels of high-density lipoprotein and its lipoprotein subfractions apolipoprotein (Apo-A) and Apo-A1 were higher, and low-density lipoprotein, Apo-B and triglycerides were significantly lower in the experimental group. The value of risk factors from the family history was the same in both groups, but the behavioural and physical risk factors such as smoking and percentage of body fat were lower in the trained group. It would appear that the group of adolescents, trained for several years in athletics and swimming, had a more beneficial lipoprotein profile and a lower level of behavioural and physical risk factors than the control group. For methodological reasons it remains an open question whether these profile differences are the consequences of self-selection procedures or the effects of training.

    Notes: Abstract We identified twoα-emitting isotopes of element 107 with masses of 261 and 262 respectively by parent-daughter correlations. For the isotope with mass 262 we found two transitions with (102±26) ms and (8.0±2.1) ms half-life, which we assign to the groundstate and to an isomeric transition, respectively. The half-life of the isotope with mass 261 is (11.8 −2.8 +5.3 ) ms. Spontaneous fission, which could be assigned to the decay of an isotope of element 107, was not detected in our experiments. This observation is in-line with our previous results, indicating a region of nuclei with strong microscopic stabilisation in the trans-actinides. Both new isotopes were produced by complete fusion of209Bi with54Cr. The production cross sections are (163±34) pb for262107 and (36 −14 +22 ) pb for261107.

    Notes: Abstract The beta-gamma spectroscopic study of22O is presented. This nucleus, produced as a projectile-like fragment from the interaction of a 60 MeV/n40Ar beam with a Be target, has been separated by the LISE spectrometer. Several gamma rays from22O decay have been observed, from which a half-life of (2.25±0.15)s has been determined. Accurate excitation energies have been deduced for several states in22F. A partial beta decay scheme of22O has been established. Experimental results have been compared with shell model calculations.
