We introduce left and right series of semi-braces. This allows to define nilpotent study the structure such semi-braces generalize some results, known for skew braces, B that set additive idempotents E is an ideal . Finally we concept a semi-brace show multiplicative group nilpotent.

BACKGROUND Shoulder injuries remain one of the most common injuries among collegiate football athletes. Offensive linemen in particular are prone to posterior labral pathology. PURPOSE To evaluate the efficacy of shoulder bracing in collegiate offensive linemen with respect to injury prevention, severity, and lost playing time. STUDY DESIGN Cohort study; Level of evidence, 3. METHODS Offe...

Methods A total of 76 consecutive adolescent idiopathic scoliosis patients who were treated with brace were included in this study. 45 patients were treated with SpineCor brace, 31 patients were treated with rigid braces. After detailing braces and their costs, choice was made by patients’ family. Patient’s height, T1-Coccyx distance, gibbosity, and Cobb angles were documented at the beginning ...

This paper describes an experimental investigation into the seismic behavior and efficiency of steel frames with special bracing infills. Cold formed steel studs (CFSS), typically used in nonstructural partition walls, were studied to determine if they could be used to laterally restrain braces against buckling and thus enhance their seismic performance. Four specimens were ductile designed and...

This paper experimentally investigates the cyclic inelastic performance of concentrically braced frames with and without cold formed steel stud ~CFSS! infills designed to laterally restrain braces and delay their buckling. Specimens have either diagonal tube or solid bar braces with and without CFSS and U brackets providing out-of-plane and in-plane buckling restraint. Behavioral characteristic...

CLINICAL SCENARIO Ankle injuries constitute a large number of injuries sustained by adolescent athletes participating in high school athletics. Prophylactic ankle bracing may be an effective and efficient method to reduce the incidence of ankle injuries in adolescent athletes in the secondary-school setting. CLINICAL QUESTION Do prophylactic ankle braces reduce the incidence of acute ankle in...

As a form of treatment in cerebral palsy, bracing has yet to meet universal acceptance. 2 , 5 , 6 Besides published opinions slighting the value of braces, in practice one frequently encounters a prejudice against prescribing them in "spastic" disease. This attitude, it must be granted, is not groundless. Phelps, 4 a proponent of braces, refers to the danger of aggravating spasticity with brace...

background: rupture of anterior cruciate ligament (acl) would cause instability and disability and if left untreated. reconstruction is performed by different techniques including patellar bone graft, as the strongest device. application of brace after acl reconstructions has revealed doubtful results.   methods: one hundred acl ruptured patients randomized into two groups were reconstructed wi...
