The method for an experimental determination of the stellar enhancement factor for the cross section of the 151Sm(n,γ) reaction process is proposed. This study offered the pretext for an excursus on the interconnections between capture and dissociation reactions and the interplay between theory and experiments in the determination of neutron capture cross sections.

Neutrophil polarity relies on local, mutual inhibition to segregate incompatible signaling circuits to the leading and trailing edges. Mutual inhibition alone should lead to cells having strong fronts and weak backs or vice versa. However, analysis of cell-to-cell variation in human neutrophils revealed that back polarity remains consistent despite changes in front strength. How is this bufferi...

The aim of this study was to compare the trends in the prevalence of back pain between several population subgroups and to assess the stability of the associations between back pain and its potential risk factors. Five cross-sectional surveys with independent random samples were conducted in two provinces in eastern Finland every fifth year from 1972 to 1992. There were 29,043 respondents aged ...
