Dental restoration begins with removing carries and affected tissues with air-turbine rotary cutting handpieces, and later restoring the lost tissues with appropriate restorative materials to retain the functionality. Most restoration materials eventually fail as they age and need to be replaced. One of the difficulties in replacing failing restorations is(More)
Dental implants are ideally placed in an orientation that allows vertical transfer of occlusal forces along their long axis. Nevertheless, optimal situations for implant placement are seldom encountered resulting in implants placement in angulated positions, which may affect their long-term success. The resonance frequency (RF) is an objective tool used to(More)
Ignition characteristics of SWCNTs with an ordinary camera flash are reported here. The ultimate goal of the work is to use SWCNT or other nanostructured materials as a means for distributed ignition in liquid rocket fuel sprays and homogeneous-charged compression ignition (HCCI) engines. The idea was originally proposed by the author in April 2003 and(More)
