BACKGROUND The study aimed to establish the prevalence of heavy drinking, evaluate correlations between heavy drinking and socio-demographic factors, physical and psychiatric conditions, and assess the impact of heavy drinking on quality of life and days of work-loss. METHODS Data from a nationally-representative cross-sectional sample were used. The sample comprised 6616 community-dwelling S...

Abstract Introduction Heavy vehicle drivers (HVDs) frequently experience reduced sleep due to travelling long distances under non-standard work hours. Short in HVDs can increase risk of motor crashes and falling asleep while driving. This study sought examine the influence break duration between shifts, onset time, prior shift on HVDs’ total time (TST) consecutive interaction time. Methods Twen...

The spectrum of baryons containing heavy quarks of one flavor is described in terms of representations of the group SU(2) × SU(6), where the two factor groups refer to spin rotations of the heavy quarks and spin-flavor rotations of the light quarks, respectively. This symmetry has a natural interpretation in the heavy quark limit. We exhibit the decomposition of baryon mass operators under this...

Extraction of correct mass splittings between vector and pseudoscalar mesons remains a challenging problem in lattice QCD. While quenched lattice QCD has been unable to extract correct mass splittings [1], so far this problem persists even with full lattice QCD [2]. One may thus ask whether lattice results for baryon mass splittings exhibit similar suppression compared to experimental numbers. ...
