Laser‐Induced Graphene from Waste Almond Shells

open access: yesAdvanced Functional Materials, EarlyView.
Almond shells, an abundant agricultural by‐product, are repurposed to create a fully bioderived almond shell/chitosan composite (ASC) degradable in soil. ASC is converted into laser‐induced graphene (LIG) by laser scribing and proposed as a substrate for transient electronics.

Ferroelectricity in Antiferromagnetic Wurtzite Nitrides

open access: yesAdvanced Functional Materials, EarlyView.
We establish MnSiN2${\rm MnSiN}_2$ and MnGeN2${\rm MnGeN}_2$ as aristotypes of a new multiferroic wurtzite family that simultaneously exhibits ferroelectricity and antiferromagnetism with altermagnetic spin splitting. By strategically substituting alkaline‐earth metals, we predict new materials with coexisting switchable polarization, spin texture, and

Effect of fatigue on joint position sense of the knee

Journal of Orthopaedic Research, 1986
AbstractThis study was designed to test position sense of the knee joint before and after fatigue in order to determine whether muscle or capsular receptors are the primary sensors for joint position sense. Reproduction of passive positioning and detection of the onset of motion (kinesthesia) were employed to measure joint position sense.

Joint position sense in the normal and pathologic knee joint

Journal of Electromyography and Kinesiology, 1991
Joint position sense has been suggested to be an important factor in the etiology of degenerative joint disease. It is also believed to be important in the rehabilitative process after reconstructive surgery of the knee. Despite this awareness, in many areas of orthopaedic surgery little effort has been devoted to study of this crucial topic. Therefore,

The Effects of Muscle Fatigue on Shoulder Joint Position Sense

open access: yesThe American Journal of Sports Medicine, 1998
Proprioception, or joint position sense, probably plays an important role in shoulder joint function. In this study, we assessed the effect of muscle fatigue on shoulder proprioception in 20 volunteers with no shoulder abnormalities. Shoulder proprioception was measured as the threshold to first detection of humeral rotation with the joint at 90° of ...

Effects of cold water immersion on knee joint position sense in healthy volunteers

open access: yesJournal of Sports Sciences, 2011
The purpose of this study was to determine the effects of cryotherapy, in the form of cold water immersion, on knee joint position sense. Fourteen healthy volunteers, with no previous knee injury or pre-existing clinical condition, participated in this ...

The effect of eccentric exercise on position sense and joint reaction angle of the lower limbs

open access: yesMuscle and Nerve, 2007
Impaired position sense and impaired joint reaction angle of the lower limbs after muscle-damaging activities is a serious functional limitation that may lead to an increased risk of injury, particularly in older populations.

JOINT POSITION SENSE

Brain, 1980
The effects of isometric and isotonic force production on perceived static joint position were investigated in 12 adult subjects. The joint examined was the proximal interphalangeal joint of one index finger, and its perceived position was determined from matching movements of the equivalent joint on the other hand. When the perturbed joint was free to

Joint position sense – There׳s an app for that

Journal of Biomechanics, 2016
Traditionally, proprioception has been assessed with a passive model, in which an external apparatus moves a body segment. Recently, protocols have been developed based on active movements, which are more representative of functional activities. However, even these approaches require expensive testing equipment and the necessity of a visit to a ...
