Abstract---In this work a pseudo-three-dimensional analytical model is developed for the steady incompressible vapor and liquid flow in an asymmetrical disk-shaped heat pipe. The hydrodynamic coupling of the vapor and liquid flow, the gravitational effects and the effects of non-Darcian transport through the porous wick are incorporated in the model, and the variations in upper and lower liquid...

Cognitive therapy (CT) and interoceptive exposure (IE) as treatments of panic disorder without agoraphobia were compared in a sample of 69 patients, randomly allocated to condition. There were no significant differences between treatments as to reductions in panic frequency, daily anxiety levels and a composite questionnaire score, at posttest after the 12-session treatment, and at both follow-...

BACKGROUND Today the majority of wild great ape populations are found outside of the network of protected areas in both Africa and Asia, therefore determining if these populations are able to survive in forests that are exploited for timber or other extractive uses and how this is managed, is paramount for their conservation. METHODOLOGY/PRINCIPAL FINDINGS In 2007, the "Kinabatangan Orang-uta...

The impact of three treatment strategies for Trypanosoma evansi control on horse mortality in the Brazilian Pantanal based on four size categories of cattle ranches is explored. The region's 49,000 horses are indispensable to traditional extensive cattle ranching and T. evansi kills horses. About 13% of these horses would be lost, annually, due to T. evansi if no control were undertaken. One pr...

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...
