Optimum tendon layout of prefabricated prestressed concrete beams was an early application of design optimization methodologies. However, most of the approaches found in the literature were not suitable to be implemented in real life bridge engineering. To fill the existing gap research has been conducted in past years by the authors to optimize prefabricated concrete beams formulating the prob...

BACKGROUND Evaluation of the effectiveness of three different types of prefabricated foot orthotics in the treatment of plantar fasciitis. METHODS Prospective, randomized head-to-head trial in 30 adults (21 women, 9 men) with plantar fasciitis without any anatomic alterations. Three different prefabricated orthotics were tested (thin, non supportive orthotic (NO); soft supportive foam orthoti...

We sought to determine whether one of two prefabricated insole designs could better manage high forefoot plantar pressures in patients with rheumatoid arthritis. Ten subjects with rheumatoid arthritis who experienced pain with shod weightbearing were studied by using a plantar pressure measurement system. Two insole designs and a shoe-only control condition were randomly tested in repeated tria...

The partially prefabricated laminated (RC) walls mentioned is this kind of seismic prevention element with part prefabricated concrete plate and cast in place concrete plate. 4 typical laminated walls without openings, 4 laminated walls with openings, and 1 common cast-in-place RC walls were tested under cyclic test. The seismic behaviour were analysed by the finite element software based on th...

BACKGROUND The search for new surgical flap techniques and modifications of already existing ones is gaining increasing popularity. Progress in flap designing and harvesting have improved the functional and aesthetic results, especially in head and neck reconstruction. MATERIAL/METHODS Ten pigs were used in this study. In the first operation, high-density porous polyethylene prefabrication wa...

UNLABELLED The present report describes the application of a miniplate in the hard palate of a 36-year-old patient with a large anterior maxillary defect. The combination of orthodontic elastics with a titanium miniplate improved the stability of the prefabricated prosthesis. This structure retained the ointment gauze covering the wounds and maintained the facial contour. In addition, contractu...

PURPOSE Biologic valved-conduit grafts avoid the need for anticoagulation and can exploit the excellent hemodynamic performance of stentless valves. Incorporation of sinuses of Valsalva into the neoaortic root can improve the function of the stentless valves. DESCRIPTION Here we present a novel prefabricated stentless valved conduit incorporating sinuses of Valsalva and describe the technique...

OBJECTIVE The aim of this study was to determine bonding properties of two types of fibre-reinforced composite (FRC) posts cemented into root canals of molars. Serrated titanium posts served as reference. METHODS Prefabricated carbon/graphite FRC posts with cross-linked polymer matrix and individually formed glass FRC posts with interpenetrating polymer network (IPN) polymer matrix were compa...

One of the common concrete channels in irrigation networks is the semielliptical prefabricated channels. Manning formula is usually used to design these channels. The cross-sectional area and the wetted perimeter are required to be calculated in Manning formula. There are no analytical solutions to directly compute these parameters. Thus, numerical integration methods are inevitably used. In th...

The increased use of prefabricated components, the complexity of new building shapes, and the speeding up of production in construction, demand an efficient and precise dimensional control. Meanwhile Information and Communication Technology (ICT) increasingly supports construction, among others, CAD systems and Total Stations, are being used for the purpose of dimensional control. In order to i...
