Information technology has changed the way organizations function. This resulted in the reliance of help desks to deal with information technology related areas such as hardware, software, and telecommunication. Besides, the adoption of business process reengineering and downsizing have led to the shrinkage of the size of help desk. The shorter information technology product life cycle has wors...

PURPOSE OF THE STUDY The present study aimed to analyse both, the functional outcome and quality of life after surgical treatment of periprosthetic fractures following TKA. MATERIAL AND METHODS A retrospective review of all periprosthetic fractures following knee arthroplasty which have been surgically treated at our institution between January 2005 and January 2012 was conducted. Beside epidem...

Analysis of the catalytic activity of identical mutations in the catalytic cores of nHH8, a very active "extended" hammerhead, and HH16, a less active "minimal" hammerhead, reveal that the tertiary Watson-Crick base pair between C3 and G8 seen in the recent structure of the Schistosoma mansoni extended hammerhead can be replaced by other base pairs in both backgrounds. This supports the model t...

Nowadays, the industrial competition is based on the Total Cost Ownership of the products (TCO). This is particularly true for big complex systems such as helicopters, for which the maintenance costs, often takes the largest part of this TCO. Thus the challenge for such integrators is to invest in reliability engineering projects aimed at increasing their product’s reliability to market them wi...

Endocardial cushions are critical to maintain unidirectional blood flow under constantly increasing hemodynamic forces, but the interrelationship between endocardial cushion structure and the mechanics of atrioventricular junction function is poorly understood. Atrioventricular (AV) canal motions and blood velocities of embryonic chicks at Hamburger and Hamilton (HH) stages 17, 21, and 25 were ...

PURPOSE This study analyzed the type of acute urinary retention (AUR) and evaluated the treatments used, including trial without catheter (TWOC). MATERIALS AND METHODS This study was based on 299 patients who were treated for AUR from January 2007 to August 2009. The patients were classified into the spontaneous AUR group (group S) and the precipitated AUR group (group P), in which AUR was co...
