We prove a criteria for nilpotency of left braces in terms the $\star$-central series and also discuss Noetherian braces, obtaining some their elementary properties. show that if finitely generated brace $A$ is Smoktunowicz-nilpotent, then additive multiplicative groups are likewise generated.

the seismic performance of hybrid braces composed of steel and shape memory alloy (sma) was investigated in this paper. six types of hybrid braces were used, constituted by sma content of 0, 20, 40, 60, 80, and 100%. a nonlinear dynamic analysis was performed under el centro earthquake records, with the maximum acceleration of 0.6g and 0.9g. our results showed that the seismic performance, i.e....

Orthodontic treatment typically occurs during early childhood and adolescence but the wearing of dental braces is often associated with sudden changes in eating patterns that prolong treatment into the teenage years. Despite these changes, psychological assessments related to eating disorders during the course of orthodontic treatment are often ignored. Based on the findings of the present case...

Introduction SpineCor and rigid braces have both results testifying their effectiveness in Adolescent Idiopathic Scoliosis (AIS) treatment: an RCT recently compared the two showing the superiority of rigid braces. Since some years we introduced SpineCor as a treatment for patients at curves between 20 and 30 Cobb degrees to improve the quality of life and reduce rigid bracing. The objective of ...

Knee bracing has been used to realize a variety of functional outcomes in both sport and rehabilitation application. Much of the literature focuses on the effect of knee misalignment, force reduction and superiority of custom braces over commercial over-the-counter braces. Efforts on developing exoskeletons to serve as knee augmentation systems emphasize actuation of joints, which then adds to ...
