Objective The increasing burden associated with low back pain (LBP) is a critical issue. This is a novel analysis of trends in risk factors for LBP aiming to identify risk factors that require further attention or consideration in global policies to reduce the burden of LBP.

Linking Vibrational Dynamics to Local Electronic Structure: Local Analysis of Dynamics of the relaxed Si$_{87}$ Cluster [PDF]
A flexible scheme for decomposing the vibrational density of states in terms of pair vibrational density of states is presented. This scheme provides the linkage between the site vibrational density of states and pair vibrational density of states so that vibrational modes, in particular localized modes, can be conveniently examined in terms of the ...

The effect of controlled vibrations on the width boundary layers during crystal growth by the Bridgman method [PDF]
By using the finite element code ASTRA, the effect of vibrations on the melt flow in Bridgman crystal growth is investigated for the Earth and Space gravity conditions. It is found that the vibrations significantly decrease the width of interfacial boundary layers in Bridgman crystal growth with submerged vibrator.

Skyrmion Vibration Modes within the Rational Map Ansatz [PDF]
We study the vibration modes of the Skyrme model within the rational map ansatz. We show that the vibrations of the radial profiles and the rational maps are decoupled and we consider explicitly the case B=1, B=2 and B=4. We then compare our results with the vibration modes obtained numerically by Barnes et al.

Sensitivity of the mussel Mytilus edulis to substrate‑borne vibration in relation to anthropogenically generated noise [PDF]
© 2015 Inter-Research. Many anthropogenic activities in the oceans involve direct contact with the seabed (for example pile driving), creating radiating particle motion waves.

Low-frequency vibrations of water molecules in minor groove of the DNA double helix [PDF]
The dynamics of the structured water molecules in the hydration shell of the DNA double helix is of paramount importance for the understanding of many biological mechanisms. In particular, the vibrational dynamics of a water spine that is formed in the DNA minor groove is the aim of the present study.

Definition and Quantification of Shock/Impact/Transient Vibrations [PDF]
Vibration injury in the hand-arm system from hand-held machines is one of the most common occupational health injuries and causes severe and often chronic nerve and vascular injury to the operator. Machines emitting shock vibrations, e.g., impact wrenches have since long been identified as a special risk factor.

The effects of absorber attachment location on vibration response of simply supported plate [PDF]
Vibration analysis of thin walled structure has been an active research in engineering fields. This paper proposed to investigate the application of vibration absorber (VA) attached to the simply supported plate (SSP) in order to suppress the structural ...
