Oral health messages for Australia: A national consensus statement.

Background: Oral health promotion initiatives must be evidence-based and consistent with broader health messaging. The Oral Health Messages for the Australian Public were first produced in 2009 and sought to enable a focused, and strategic approach to oral health promotion in Australia. As the evidence base and needs of the Australian population have since changed, this consensus statement was updated in 2022-2023.

Origin of the Resistive Anisotropy in the Electronic Nematic Phase of BaFe(2)As(2) Revealed by Optical Spectroscopy.

We perform, as a function of uniaxial stress, an optical-reflectivity investigation of the representative "parent" ferropnictide BaFe(2)As(2) in a broad spectral range, across the tetragonal-to-orthorhombic phase transition and the onset of the long-range antiferromagnetic (AFM) order. The infrared response reveals that the dc transport anisotropy in the orthorhombic AFM state is determined by the interplay between the Drude spectral weight and the scattering rate, but that the dominant effect is clearly associated with the metallic spectral weight. In the paramagnetic tetragonal phase, though, the dc resistivity anisotropy of strained samples is almost exclusively due to stress-induced changes in the Drude weight rather than in the scattering rate, definitively establishing the anisotropy of the Fermi surface parameters as the primary effect driving the dc transport properties in the electronic nematic state.

[Sex hygiene of the athlete and related problems].

The Author tries to summarize in a few pages the problems of sex hygiene and of sexual education in general and of athletes in particular. This is a problem which risks to be exasperated because it had not been treated in the past and because now it is too much in information only. This work is a contribution to education purposes.
