Quantum Gravity Hamiltonian for Manifolds with Boundary
, 1995 In canonical quantum gravity, when space is a compact manifold with boundary there is a Hamiltonian given by an integral over the boundary. Here we compute the action of this `boundary Hamiltonian' on observables corresponding to open Wilson lines in the

Rest breaks – a countermeasure for work-related injuries?
Scandinavian Journal of Work, Environment & Health, 2014 The main idea behind supplementary rest breaks within a work shift is to promote recovery from work, a process known to be important for health in the long-run (1). Supplementary rest breaks are also used to promote occupational safety.

The role and implications of mammalian cellular circadian entrainment
FEBS Letters, EarlyView.At their most fundamental level, mammalian circadian rhythms occur inside every individual cell. To tell the correct time, cells must align (or ‘entrain’) their circadian rhythm to the external environment. In this review, we highlight how cells entrain to the major circadian cues of light, feeding and temperature, and the implications this has for our

Superconductivity in a two dimensional extended Hubbard model
, 2005 The Roth's two-pole approximation has been used by the present authors to investigate the role of $d-p$ hybridization in the superconducting properties of an extended $d-p$ Hubbard model.

Management of work-relevant upper limb disorders: a review [PDF]
, 2008 Background Upper limb disorders (ULDs) are clinically challenging and responsible for considerable work loss. There is a need to determine effective approaches for their management.

Shift work, sleep, and sleepiness - differences between shift schedules and systems
Scandinavian Journal of Work, Environment & Health, 2010 In this narrative review, we examined what level of research evidence is available that shift workers’ sleep–wake disturbances can be minimized through ergonomic shift scheduling.

Crosstalk between the ribosome quality control‐associated E3 ubiquitin ligases LTN1 and RNF10
FEBS Letters, EarlyView.Loss of the E3 ligase LTN1, the ubiquitin‐like modifier UFM1, or the deubiquitinating enzyme UFSP2 disrupts endoplasmic reticulum–ribosome quality control (ER‐RQC), a pathway that removes stalled ribosomes and faulty proteins. This disruption may trigger a compensatory response to ER‐RQC defects, including increased expression of the E3 ligase RNF10 ...

Impact of gambling technologies in a multi-media world [PDF]
, 2006 In many countries there appears to be a slow shift from gambling being taken out of gambling environments and into the home and the workplace. Historically, what we have witnessed is a shift from destination resorts (such as Las Vegas and Atlantic City ...

Occupational Safety Climate and Shift Work
Chemical Engineering Transactions, 2013 Developing and maintaining a rich safety culture is an important factor in achieving a safe workplace with low injury rates. Safety climate measures provide a snapshot of the safety culture, as they reflect workers’ shared perceptions of how management ...

Peptide‐based ligand antagonists block a Vibrio cholerae adhesin
FEBS Letters, EarlyView.The structure of a peptide‐binding domain of the Vibrio cholerae adhesin FrhA was solved by X‐ray crystallography, revealing how the inhibitory peptide AGYTD binds tightly at its Ca2+‐coordinated pocket. Structure‐guided design incorporating D‐amino acids enhanced binding affinity, providing a foundation for developing anti‐adhesion therapeutics ...
