Dose–response relation between perceived physical exertion during healthcare work and risk of long-term sickness absence

open access: yesScandinavian Journal of Work, Environment & Health, 2012
OBJECTIVE: An imbalance between physical work demands and physical capacity of the worker may be a risk factor for poor health. Perceived physical exertion provides information about the individual perception of the work demands relative to the capacity ...

Modeling Brain Functional Connectivity Patterns during an Isometric Arm Force Exertion Task at Different Levels of Perceived Exertion: A Graph Theoretical Approach

open access: yesBrain Sciences, 2022
The perception of physical exertion is the cognitive sensation of work demands associated with voluntary muscular actions. Measurements of exerted force are crucial for avoiding the risk of overexertion and understanding human physical capability.

The drag exerted by weakly dissipative trapped lee waves on the atmosphere: application to Scorer's two-layer model [PDF]

open access: yes, 2022
While it is known that trapped lee waves propagating at low levels in a stratified atmosphere exert a drag on the mountains that generate them, the distribution of the corresponding reaction force exerted on the atmospheric mean circulation, defined by the wave momentum flux profiles, has not been established, because for inviscid trapped lee waves ...

Immediate risk of myocardial infarction following physical exertion, tea, and coffee: A case-crossover study in Thailand.

open access: yesPLoS ONE, 2019
BackgroundPhysical exertion and caffeine consumption are associated with acute myocardial infarction (MI). However, physical exertion and caffeine consumption have not been examined as immediate triggers of MI in low and middle-income countries ...

The Lorentz Force and the Radiation Pressure of Light [PDF]

open access: yesAJP 77, 122-127 (2009), 2008
In order to make plausible the idea that light exerts a pressure on matter, some introductory physics texts consider the force exerted by an electromagnetic wave on an electron. The argument as presented is both mathematically incorrect and has several serious conceptual difficulties without obvious resolution at the classical, yet alone introductory ...

Theoretical analysis of the force on the end face of a nano-filament exerted by an outgoing light pulse [PDF]

open access: yesPhysical Review A 80, 023823-1-7 (2009), 2012
The slight deformations observed upon transmission of a light pulse through a short length of a silica glass nano-filament offer the possibility of determining the momentum of light inside the filament. Using precise numerical calculations that take into account not only the electromagnetic momentum inside and outside the filament, but also the Lorentz

Influence of face masks on the subjective impairment at different physical workloads

open access: yesScientific Reports, 2023
To quantify the subjective and cognitive impairment caused by wearing face masks at work, 20 men and 20 women (median age 47 years, range 19–65) were tested under different ergometer workloads while wearing surgical mask, community mask, FFP2 respirator ...
