Investigating the effect of luminosity and color temperature of light sources on the extent of mental and visual fatigue under experimental conditions

open access: yesInternational Journal of Environmental Health Engineering, 2023
Aim: Undesirable lighting can affect the visual system, as well as mental, neuropsychological, and physiological efficiency of staff. The present study was done to determine the effect of luminosity and nominal correlated color temperature (NCCT) on the ...

Modelling the role of non metallic inclusions on the anisotropic fatigue behaviour of forged steel [PDF]

open access: yes, 2011
Forged components are known to show high cyclic and monotonic mechanical properties. This is mainly due to a better compactness and a finer microstructure introduced by the forming process. However, this good mechanical behaviour is sometimes a source of

Does mental fatigue affect skilled performance in athletes? A systematic review.

open access: yesPLoS ONE, 2021
BackgroundMental fatigue is a psychobiological state induced by a prolonged duration of demanding cognitive tasks. The effects of mental fatigue on physical performance have been well investigated in the literature.

On the multiaxial fatigue assessment of complex three-dimensional stress concentrators [PDF]

open access: yes, 2014
This paper assesses and quantifies the detrimental effects of complex tri-dimensional notches subjected to uniaxial and multiaxial fatigue loading. A number of experimental results taken from the technical literature and generated by testing specimens ...

The relationship between mental fatigue, depression, and cognition in Graves’ disease

open access: yesEuropean Thyroid Journal, 2023
Objective: Mental fatigue, depression, anxiety, and cognitive complaints are common in Graves’ disease (GD). Our aims were to assess the relationship between these variables in patients with GD during both hyperthyroidism and a long stable euthyroidism.

Objective Assessments of Mental Fatigue During a Continuous Long-Term Stress Condition

open access: yesFrontiers in Human Neuroscience, 2021
Prolonged periods of cognitive workload will cause mental fatigue, but objective, quantitative, and sensitive measurements that reflect long-term, stress-induced mental fatigue have yet to be elucidated.

Mental fatigue assessment may add information after aneurysmal subarachnoid hemorrhage

open access: yesBrain and Behavior, 2019
Background Mental fatigue, as part of cognitive dysfunction, has been reported to be common after subarachnoid hemorrhage and it significantly affects quality of life. Aims of the Study The aim of this study was to assess mental fatigue one year after an
