AIM Aortic dissection is a life-threatening aortic catastrophe where layers of the aortic wall are separated allowing blood flow within the layers. Propagation of aortic dissection is strongly linked to the rate of rise of pressure (dp/dt) experienced by the aortic wall but the hemodynamics is poorly understood. The purpose of this study was to perform computational fluid dynamics (CFD) simulat...

The knees of 72 patients with unilateral anterior-cruciate- ligament (ACL) injury were analyzed before ACL reconstruction as well as by follow-up arthroscopy on the day of staple removal. At ACL reconstruction 31 lateral menisci and 40 medial menisci were found to be normal. 28 lateral menisci and 24 medial menisci were treated surgically, while 13 lateral menisci and 8 medial menisci with smal...

BMJ Case Rep Published online: [please include Day Month Year] doi:10.1136/bcr-2013010389 DESCRIPTION A 38-year-old man with asymptomatic chest wall deformity presented with acute, severe retrosternal pain experienced while he was bowling. The pain radiated to the back and down to abdomen in a tearing fashion. Physical examination reveal...

The results of 37 medial canthal resection procedures performed for the correction of severe paralytic or involutional medial ectropion are presented with an average follow-up of 5.4 years. Epiphora was improved in 33 out of the 37 cases and all but one patient had an anatomically improved lid-globe apposition, medial canthal angle, and posterofixation of the medial canthus. These results confi...

Temper rolling or skin pass rolling is one of cold rolling processes composed of a horizontal pass cold rolling mill stand. In this process, the thick strip is subjected to very light reduction (0.5–4%) in thickness in the presence of high friction amplitudes. One of the basic parameters of strip rolling processes is temper rolling force. A new rolling force model has been proposed for temper r...

During casting of aluminum alloys, the partially solidified material is submitted to thermally induced strains that can lead to severe casting defects, such as hot tearing. In this work, carried out in the frame of the European project VIR[CAST], the rheological behavior of a partially solidified AA5182 aluminum alloy has been investigated in order to provide constitutive equations to predict h...
