Superlubricious Surfaces Through Surface Attached Hydrogels Obtained by C,H‐insertion Crosslinking

Advanced Functional Materials, EarlyView.
Taking synovial joints as a source of inspiration, the friction properties of surfaces covered with 1d‐swelling polyelectrolyte hydrogels in combination with a shear‐thinning aqueous lubricant are studied. Such systems obtained by C,H insertion crosslinking show superlubricious behavior, even surpassing the friction values reported for the natural ...

Posture, Postural Discomfort, and Performance [PDF]

Human Factors: The Journal of the Human Factors and Ergonomics Society, 1985
In order to justify the costs of using ergonomically designed workplaces, it is necessary to relate improved posture to improved performance. This experiment used twelve subjects, four in each of three postural conditions. Subjects inspected printed circuit boards for 3 h with two five-minute breaks per hour.

Infirmities of breath, sight, or gait, startle us. Among the patients consulting a psychiatrist, there are some who can no longer master the seemingly banal arts ...
