Comparison of Rolyan and Jamar dynamometers for measuring grip strength.
This study compared the Jamar and Rolyan hydraulic dynamometers to determine their concurrent validity with known weights as well as their inter-instrument reliability and concurrent validity for measuring grip strength in a clinical setting. Thirty females and 30 males were tested on these two grip strength measurement devices using a repeated measure design. Results showed that the Jamar and ...
متن کاملNew Insight into the Relation between Torsion and Electromagnetism
In several unified field theories the torsion trace is set equal to the electromagnetic potential. Using fibre bundle techniques we show that this is no leading principle but a formal consequence of another geometric relation between space-time and electromagentism. ∗E-mail: [email protected] Torsion in general relativity is commonly studied within the framework of Einstein–Carta...
متن کاملHigh-pressure torsion for new hydrogen storage materials
High-pressure torsion (HPT) is widely used as a severe plastic deformation technique to create ultrafine-grained structures with promising mechanical and functional properties. Since 2007, the method has been employed to enhance the hydrogenation kinetics in different Mg-based hydrogen storage materials. Recent studies showed that the method is effective not only for increasing the hydrogenatio...
متن کاملA New Instrument for Measuring Tibial Torsion in Pediatric Patients
OBJECTIVE To develop and test the validity and reliability of a new instrument for measuring the thigh-foot angle (TFA) for the patients with in-toeing and out-toeing gait. METHODS The new instrument (Thigh-Foot Supporter [TFS]) was developed by measuring the TFA during regular examination of the tibial torsional status. The study included 40 children who presented with in-toeing and out-toei...
متن کاملModel-based Control Design for Ic-engines on Dynamometers: the Toolbox 'optimot'
: A new approach towards a model-based optimization of IC engine control on dynamometers is presented in this paper. The proposed methodology comprises advanced measurement strategies for a fast dynamic measurement of engine characteristics on dynamometers (DYNMET), a model-based offline optimization of feedforward control maps (STATOPT), and the optimization of dynamic transitions of turbochar...
