Low‐Angle Grain Boundaries and Re‐Segregation in Single‐Crystalline Ni‐Base Superalloys

Advanced Engineering Materials, EarlyView.
This work demonstrates that Re‐segregation at low‐angle grain boundaries (LAGBs) in Ni‐base superalloys is influenced by misorientation angle. Advanced microscopy and atom probe tomography reveal that higher misorientation angles increases Re‐segregation.

Bilateral Isokinetic Peak Torque, Torque Acceleration Energy, Power, and Work Relationships in Athletes and Nonathletes [PDF]

Journal of Orthopaedic & Sports Physical Therapy, 1987
Clinicians frequently assume the uninjured extremity can be used as a predictor of preinjury strength for return of the injured extremity to a normal state during rehabilitation. The purpose of this study was to examine differences in bilateral isokinetic peak torque (PT) at 60 and 180 O/sec, and torque acceleration energy (TAE), average power (AP ...

Affecting the Properties of Copper–Graphene Electroconductive Composite by Severe Plastic Deformation

Advanced Engineering Materials, EarlyView.
Copper‐based composites enhanced with carbon feature convenient mechanical properties and favorable electric conductivity. Processing via deformation and thermomechanical treatments can introduce advantageous microstructures further enhancing their performance. Herein, copper–graphene powder‐based composites are directly consolidated via rotary swaging

Análise isocinética da articulação do cotovelo em crianças com paralisia cerebral Isokinetic analysis of the elbow joint in children with cerebral palsy

Motriz: Revista de Educacao Fisica, 2012
A quantidade de torque aplicado na articulação é uma medida de aptidão física importante para crianças com paralisia cerebral. O presente estudo analisou parâmetros cinéticos na articulação do cotovelo em crianças saudáveis e com paralisia cerebral ...

Optimization of the Production of Rubber Compounds Using Mathematical Models

Advanced Engineering Materials, EarlyView.
Rubber compounds were mixed in a batch internal mixer, and symbolic regression was used to derive mathematical models linking recipe and process parameters to ram path, torque, and mixing quality (incorporation, dispersion, distribution). Subsequent optimization with evolutionary algorithms identified operating conditions that reduce specific energy ...

Isokinetic evaluation of knee muscles and correlation of maximum torque of the extensors of the operated knee with thigh circumference in soccer players 2 years after ACL reconstruction: A cross-sectional study

Hong Kong Physiotherapy Journal
Background: Anterior cruciate ligament reconstruction (ACLR) often results in residual strength deficits in knee muscles, which may affect an athlete’s return to performance. Isokinetic testing and thigh circumference measurements offer valuable insights

Molecular Dynamics Studies of Shape Memory Polymers: From Bead–Spring Models to Atomistic Simulations

Advanced Engineering Materials, EarlyView.
Coarse‐grained (left) and atomistic (right) models of the shape memory polymer ESTANE ETE 75DT3 are shown schematically. The two representations bridge molecular detail and mesoscopic description. Both models capture shape memory behavior, linking segmental mobility and conformational relaxation of anisotropic chains to macroscopic recovery, and ...

Hamstring Torque, Velocity and Power Elastic Band Measurements during Hip Extension and Knee Flexion

Applied Sciences, 2021
The quantitative dynamic monitoring of the performance of hamstring muscles during rehabilitation and training cannot currently be undertaken using elastic resistance bands. Hip extension with a fully extended knee involves hamstring agonists, while knee

Eccentric Peak Torque of the Plantar and Dorsiflexors Is Maintained in Older Women [PDF]

The Journals of Gerontology Series A: Biological Sciences and Medical Sciences, 1997
Although a relative preservation of eccentric (ECC) strength with age has been reported previously, this phenomenon has not been studied in lower leg muscles. Concentric (CONC) and ECC plantar (PF) and dorsiflexion (DF) in healthy active older women (OW; n = 16, age = 67 +/- 4 years) and younger women (YW; n = 16, age = 27 +/- 4 years) were studied ...

Experimental Characterization and Constitutive Modeling of the Effect of Prior Inelastic Strain on the Viscoplastic Behavior of AD730 at 700 °C

Advanced Engineering Materials, EarlyView.
This study shows that superalloys used in aircraft engine disks become much more prone to deformation at high temperatures if they have been strained during manufacturing. This effect increases with the level of prior strain but eventually reaches a limit.
