Background: A thoracic curve degree of greater than 45° leads to thoracic hyperkyphosis, and its common treatment method is orthotic treatment. The acceptance rate of spinal orthosis depends on in-brace correction, patient`s compliance and quality of life. Objective: In this study, we aimed to compare in-brace correction, compliance and quality of life in patients with thoracic hyperkyphosis ...

in the present study, turbulent flow in channels of a plate heat exchanger with corrugated chevron plates has been simulated numerically using the commercial cfd package, fluent. unstructured mesh is used for discretizing the computational domain and simple algorithm is utilized to solve the pressure and velocity equations. there is a wide selection of different plate heat exchangers within the...

Results For the 22 symmetric CAD TLSOs, initial in brace correction of thoracic curves was 9.1 degrees, with average out of brace thoracic curve 25.2 degrees, and lumbar curve correction of 10.3 degrees, with average out of brace lumbar curve 27.8 degrees. The percentage of correction in CAD versions was 36.1% thoracic, and 37.1% lumbar. For the 12 asymmetric, TLSOs molded supine with manipulat...

STUDY DESIGN Retrospective controlled cohort study comparing the in-brace correction of two samples of scoliosis patients with braces of different computer aided design (CAD). PURPOSE In-brace correction and compliance correlate with outcome. The more standardized CAD braces that are available should enable improved in-brace correction and outcome. This study compared recent CAD brace develop...

An investigation of MWPCs with interpolating chevron shaped cathode pad readout has been carried out as part of the R&D for the particle tracking system of the PHENIX detector at RHIC. Two prototype chambers were designed and constructed. Their response to minimum ionizing particles was tested with secondary beams from the Alternating Gradient Synchrotron (AGS) at Brookhaven National Laboratory...

Solution phase post-modification of a trimesic acid (TMA) network on Au(111) with Zn(2+) ions was found to induce transformation of a bar-featured scanning tunneling microscopy image of (5√3 × 5√3) to a chevron-pair image of (10√3 × 10√3). Voltammetric determination of Zn coverage in the modified TMA network supports the fact that the chevron feature consists of three TMA molecules combined via...

BACKGROUND The CMCR brace (Corset MonocoqueCarbone respectant la Respiration -which means Monoshell Carbon Brace respecting Breathing) is an innovative brace, used in orthopaedic treatment for progressive thoracic, thoraco-lumbar or combined scoliosis, whatever their etiology. It can be used at the very young age without disrupting the chest growth, but should be kept for reducible scoliosis in...

Bad Sobernheim Stress Questionnaire (BSSQ)-Deformity and BSSQ-Brace are the most widely used instruments for evaluating stress levels in adolescent idiopathic scoliosis (AIS) patients under brace treatment, and good reliability and validity have been demonstrated across different cultures. Great stress has been found among many adolescents, becoming a major concern for professionals. However, n...

In this paper, a new type of combined wind-wave system is proposed, that is, composite bucket foundation-oscillating buoy (CBF-OB) device. A three-dimensional numerical wave flume established by using the renormalization group k–ε model. The hydrodynamic characteristics around and power generation device are studied. relationship between parameters run-up pressure analyzed. absorption efficienc...
