Computational fluid dynamic studies of 3-D, fixed geometry, gore-shaped parachute canopies are presented. Both solid and ribbon canopies with a 10% vent diameter are investigated. The flowfields analyzed are laminar and compressible, broaching both the subsonic and supersonic regimes. Results presented include characterization of the local and global flowfields and the internal and external can...

Femur fractures occur during broaching and impaction of the implant during hip arthroplasty. Prophylactic cerclage of the proximal femur with braided cable and steel wire has been shown to decrease hoop stresses and has been posited as a way to decrease the incidence of intraoperative fracture. In this biomechanical study, the authors investigated the strain across the proximal femur during bro...

OBJECTIVE To assess the initial stability of anatomical stems implanted in manually broached femoral cavities compared with that assessed in cavities milled with the robodoc system. DESIGN The bone-prosthesis interface motion was measured in matched pairs of cadaveric femora to assess the initial stability of anatomical stems implanted with two different implantation techniques. BACKGROUND ...

Electrochemical machining (ECM) is a non-traditional machining process used mainly to cut hard or difficult to cut metals, where the application of a more traditional process is not convenient. It offers several special advantages including higher machining rate, better precision and control, and a wider range of materials that can be machined. A suitable selection of machining parameters for t...

some of the most destructive accidents of 1980s and 90s which occurred in process industries were domino accidents. although domino accidents are among the most destructive industrial accidents, there are not much pioneering works done on quantification of them. the analytical formulation of the domino accidents is usually complex and need a deep knowledge of probability rules. even if the case...

Psikolojik danışmanlık disiplini son 40 yıldır kültüre duyarlılık üzerine odaklanmaktadır. Bu sürecin sonucu olarak duyarlı psikolojik danışma süreci kavramsallaştırılmış ve bu konuda birçok teori model geliştirilmiştir. Dünyada olduğu gibi Türkiye’de de en yaygın kullanılan modelleri bilgi, farkındalık beceri bileşenlerinden oluşmaktadır. Fakat alanda çalışan danışmanın kültürel bilgi seviyele...
