Quality Enhancement of Laser Powder‐Bed Fusion Parts by Acoustically Assisted Additive Manufacturing by Laser Powder‐Bed Fusion and its Application to Lattice Structures

Advanced Engineering Materials, EarlyView.
Additive manufacturing technologies like laser powder‐bed fusion offer great design freedom and individualization of products down to a batch size of one. However, parts fabricated with this technology suffer from poor quality. Acoustic assistance during the build process can minimize these drawbacks.

A Simulative Approach for the Prediction of Mesoscale Residual Stress Fields in Solution‐Strengthened Ferritic Ductile Iron

Advanced Engineering Materials, EarlyView.
This study presents a 3D representative volume element‐based simulation approach to predict mesoscopic residual stress and strain fields in silicon solid solution‐strengthened ductile cast iron. By modeling phase transformation kinetics with an enhanced Johnson–Mehl–Avrami–Kolmogorov model, the effects of varying cooling rates on residual stresses are ...

Vacuum‐Formed Composites Based on a Polyolefin and a High Content of Biomass‐Waste Fillers

Advanced Engineering Materials, EarlyView.
It is shown here that by the use of a very ductile polymer matrix, it is possible to vacuum‐form products that contain up to 25% of hard biofillers with still ductile properties. The results are promising and opens up for the use of engineered biocomposites derived from industrial side‐stream biofillers in vacuum‐formed products. A strategy to increase

Antimicrobial Titanium–Copper Alloys: The Role of Microstructure in Arc‐Melted Compositions

Advanced Engineering Materials, EarlyView.
Copper‐containing titanium alloys show promise in combating orthopedic implant infections. This study explores the influence of heat treatment on Ti‐11.5Cu and Ti‐33Cu alloys, revealing that larger Ti2Cu precipitates (≈5 μm) enhance antimicrobial efficacy through increased surface contact. Results suggest contact sterilization is the primary mechanism,

Balance abilities of junior ice hockey players

The Journal of Sports Medicine and Physical Fitness, 2021
Postural control is required during various fast-paced and offensive ice hockey actions, and therefore seems to be an important component in ice hockey performance.Data were collected from two ice hockey teams with differing performance levels. The higher-performance team consisted of 26 players (with ages of 16.3±0.9 y, heights of 178.26±6.71 cm, and ...

Reading and a Balanced Polymorphism for Laterality and Ability

Journal of Child Psychology and Psychiatry, 1990
Abstract The idea that reading ability might vary with right‐left hand skill, such that children with mild biases to the right hand have advantages for learning, while children at both left and right extremes have disadvantages, was supported by findings for a large sample of primary schoolchildren.

Balance Abilities of Professional Dancers on Select Balance Tests

Journal of Orthopaedic & Sports Physical Therapy, 1996
Documentation that dancers have better balance abilities than nondancers is important because of the number of dancers who sustain injury and then are referred to physical therapists for treatment. The purpose of this study was to compare balance abilities of professional dancers with nondancers on selected balance conditions.

The effects of soccer training and timing of balance training on balance ability

European Journal of Applied Physiology, 2006
The purpose of the present study was to investigate the effects of a soccer training session on the balance ability of the players and assess whether the effectiveness of a balance program is affected by its performance before or after the regular soccer training.

Balance and dyslexia: An investigation of adults’ abilities

European Journal of Cognitive Psychology, 2006
Balance ability in dyslexia is an issue of considerable theoretical and applied significance, but the literature currently lacks consensus. This study applied objective measures to established balance tasks. 17 dyslexic adults and 20 controls matched for age and IQ undertook the heel-to-toe balance test for 1 minute. Further “dual task” tests were also
