Up for the tackle? The pelvic floor and rugby. A review.

The pelvic floor and its associated disorders are a unique and often overlooked aspect of women's rugby. This review discusses relevant biopsychosocial considerations specific to the pelvic floor and rugby. Pelvic floor disorders can present at any time across the female lifespan but are more prevalent during pregnancy and postpartum.

Is your system fit for purpose? Female athlete health considerations for rugby injury and illness surveillance systems.

This review discusses female-specific health considerations in injury and illness surveillance and provides rugby-specific recommendations for future surveillance. Identifying priority injury and illness problems by determining those problems with the highest rates within women's rugby may highlight different priorities than sex comparisons between men's and women's rugby. Whilst sports exposure is the primary risk for health problems in sports injury and illness surveillance, female athletes have health domains that should also be considered.

Smooth trends in fermium charge radii and the impact of shell effects.

The quantum-mechanical nuclear-shell structure determines the stability and limits of the existence of the heaviest nuclides with large proton numbers Z ≳ 100 (refs. ). Shell effects also affect the sizes and shapes of atomic nuclei, as shown by laser spectroscopy studies in lighter nuclides.

High-resolution laser spectroscopy of singly charged natural uranium isotopes.

High-resolution collinear laser spectroscopy has been performed on singly charged ions of U at the IGISOL facility of the Accelerator Laboratory, University of Jyväskylä, in Finland. Ten ionic transitions from the and ground and first excited states were measured in the 300 nm wavelength range, improving the precision of the hyperfine parameters of the lower states in addition to providing newly measured values for the upper levels. Isotope shifts of the analyzed transitions are also reported for U with respect to U.
