This paper addresses the aerodynamic performance of Busemann-type supersonic biplanes at both design and offdesign conditions. An adjoint-based optimization technique is used to optimize the aerodynamic shape of the biplane to reduce the wave drag at a series of Mach numbers ranging from 1.1 to 1.7, at both acceleration and deceleration conditions. The optimized biplane airfoils dramatically re...

Background. The combination of Dega transililiac and femoral subtrochanteric is used in our department in the treatment of Legg-Calvé-Perthes' disease. Subtrochanteric osteotomy, initially performed as varus-derotation osteotomy, is now mainly extension osteotomy with shortening. Femoral shortening is crucial for joint decompression and makes room for pelvic redirection after pelvic osteotomy. ...

OBJECTIVE To compare postoperative maxillary stability following Le Fort I osteotomy for the correction of occlusal cant as compared with conventional Le Fort I osteotomy for maxillary advancement. STUDY DESIGN The subjects were 40 Japanese adults with jaw deformities. Of these, 20 underwent a Le Fort I osteotomy and intraoral vertical ramus osteotomy (IVRO) to correct asymmetric skeletal mor...

BACKGROUND AND PURPOSE Tibial tubercle osteotomy (TTO) is an established surgical technique for exposing the stiff kneein revision total knee arthroplasty (RTKA). The osteotomy is usually performed through the anterior metaphyseal cancellous bone of the tibia but it can be extended into the intramedullary canal if tibial stem and cement removal are necessary. Furthermore, repeat osteotomy may b...

OBJECTIVE This study aims to present a review about complications of surgical treatment of Developmental Dysplasia of the Hip and comparing the kinds and ratios of two osteotomy technique (Salter Innominate Osteotomy and Pemberton Pericapsular Osteotomy). MATERIALS AND METHODS Fifty-seven patients of 126 that had bilateral developmental dysplasia of the hip are the case series that had undewe...

AIMS The purposes of this study were to compare the accuracy of multiplane vs. biplane transoesophageal echocardiography (TEE) in the diagnosis of aortic dissection and aortic intramural haematoma, and to test whether these techniques provide all the diagnostic information required to make management decisions. METHODS AND RESULTS Fifty-eight consecutive patients with clinically suspected aor...

  Background: The aim of this review article is to analyze the results of high tibial osteotomy compared to unicompartmental knee arthroplasty in patients with unicompartmental knee osteoarthritis.   Methods: The search engine used was PubMed. The keywords were: "high tibial osteotomy versus unicompartmental knee arthroplasty". Twenty-one articles were found on 28 February 2015, but only eighte...

Title of thesis: EXPERIMENTAL INVESTIGATION OF A QUAD-ROTOR BIPLANE MICRO AIR VEHICLE Christopher Michael Bogdanowicz Master of Science, 2015 Thesis directed by: Dr. Inderjit Chopra Department of Aerospace Engineering Micro air vehicles are expected to perform demanding missions requiring efficient operation in both hover and forward flight. This thesis discusses the development of a hybrid air...

Hip dysplasia is the most common cause of secondary osteoarthritis (OA). To prevent the early onset of secondary OA, Nishio's transposition osteotomy, Steel's triple osteotomy, Eppright's dial osteotomy, Wagner's spherical acetabular osteotomy, Tagawa's rotational acetabular osteotomy (RAO), and Ganz' periacetabular osteotomy (PAO) have been proposed. PAO and RAO are now commonly used in surgic...
