BACKGROUND Platelet rich plasma is known for its hemostatic, adhesive and healing properties in view of the multiple growth factors released from the platelets to the site of wound. The primary objective of this study was to use autologous platelet rich plasma (PRP) in wound beds for anchorage of skin grafts instead of conventional methods like sutures, staplers or glue. METHODS In a single ...

As the largest filled-aperture radio telescope in world, China's five-hundred-meter diameter Aperture Spherical Radio Telescope (FAST) is supported using a unique ultra-high fatigue stress cable net structure to enable flexible deformation of reflector. each supporting cables required be capable bearing an (up approximately 500 MPa), new type anchor specially designed this paper provide high pr...

The purpose of this article is to review and update current concepts involving the use of dental implants for orthodontic anchorage. Topics to be discussed include indications, implant requirements (eg, materials, size, designs of dental implants), surgery and healing time, biomechanics and forces, loading time, implant maintenance, posttreatment considerations, and disadvantages.

This paper presents an investigation into the bond strength of three common façade stones, namely, travertine, granite, and marble, to a concrete substrate using shear-splitting test. The effects anchorage, number curing days, presence anti-freezing agent in cement–sand mortar on were studied. results show that days had significant impact between stones substrates. accelerator increased bonding...
