Interaction of Physical and Mental Work [PDF]
International Journal of Occupational Safety and Ergonomics, 2002 The objective of the research was to determine the effect of mental load on the physical capacity of an individual. An experiment involving 9 combinations of lifting tasks, 1 lowering task, and 3 treadmill tasks was conducted. Heart rate was measured and maximum acceptable weight of lift was determined using the psychophysical method.

Network topology drives population temporal variability in experimental habitat networks
Population Ecology, EarlyView.Habitat patches connected by dispersal pathways form habitat networks. We explored how network topology affects population outcomes in laboratory experiments using a model species (Daphnia carinata). Central habitat nodes in complex lattice networks exhibited lower temporal variability in population sizes, suggesting they support more stable ...

Influence of the Physical Work Environment on Work Engagement and Performance [PDF]
24th Annual European Real Estate Society Conference, 2017 In recent years, companies have made effort to adjust their offices to be more flexible and to support the activities and needs of their employees. The aim of these concepts is to increase employee satisfaction, leading to higher productivity, and at the same time save expenses due to flexible use of the workspace.

High physical work demands and working life expectancy in Denmark [PDF]
Occupational and Environmental Medicine, 2020 ObjectiveIn most European countries, political reforms gradually increase the statutory retirement age to counter the economic costs of a growing elderly population. However, working to a high age may be difficult for people with hard physical labour.

A stepwise emergence of evolution in the RNA world
FEBS Letters, EarlyView.How did biological evolution emerge from chemical reactions? This perspective proposes a gradual scenario of self‐organization among RNA molecules, where catalytic feedback on random mixtures plays the central role. Short oligomers cross‐ligate, and self‐assembly enables heritable variations. An event of template‐externalization marks the transition to

FEBS Letters, EarlyView.B cells sense external mechanical forces and convert them into biochemical signals through mechanotransduction. Understanding how malignant B cells respond to physical stimuli represents a groundbreaking area of research. This review examines the key mechano‐related molecules and pathways in B lymphocytes, highlights the most relevant techniques to ...

Student evaluations of physics teachers: On the stability and persistence of gender bias
Physical Review Physics Education Research, 2016 [This paper is part of the Focused Collection on Gender in Physics.] There is a long history of research which confounds the simple interpretation that evaluations in an educational context are purely measures of competency.

Evolutionary interplay between viruses and R‐loops
FEBS Letters, EarlyView.Viruses interact with specialized nucleic acid structures called R‐loops to influence host transcription, epigenetic states, latency, and immune evasion. This Perspective examines the roles of R‐loops in viral replication, integration, and silencing, and how viruses co‐opt or avoid these structures.

Nanoscale microwave imaging with a single electron spin in diamond
New Journal of Physics, 2015 We report on imaging of microwave (MW) magnetic fields using a magnetometer based on the electron spin of a nitrogen vacancy (NV) center in diamond. We quantitatively image the magnetic field generated by high frequency (GHz) MW current with nanoscale ...
