results in group 1, the mean largest and cumulative stone diameters, respectively, were 18.7 ± 5.7 mm and 45.0 ± 12.0 mm. in group 2, the mean volume was 6,288.4 ± 2,733.0 mm3. the overall sf was 96.4% (100% for group 1 and 75% for group 2). the mean number of sessions of eswl and urs, respectively, was 1.4 ± 0.7 and 0.8 ± 0.9 in group 1 and 4.0 ± 2.0 and 1.5 ± 1.3 in group 2. the mean times to...

STATEMENT OF PROBLEM Impacts and accidents are considered as the main fac- tors in losing the teeth, so the analysis and design of the implants that they can be more resistant against impacts is very important. One of the important nu- merical methods having widespread application in various fields of engineering sciences is the finite element method. Among its wide applications, the study of d...

ID: 8177 Title: A Clinical Example of the Helical Tomotherapy Thread Effect: Robustness Discussion Purpose: A previous study explained why pitches of 0.86/n, where n is an integer, will provide the best junctioning of a helically delivered and diverging beam. The previous treatment was theoretical and based on unmodulated examples. In this study, a clinically relevant case of a palliative lung ...

Because of fluctuation in leg tension, pitch motion is very effective fatigue and life safety of leg elements in tension leg structures (TLSs). In this paper an exact solution for pitch vibration of a TLS interacting with ocean wave is presented. The legs of TLP are considered as elastic springs. The flow is assumed to be irrotational and single-valued velocity potentials are defined. The effec...

 longevity of osseointegrated implants are intensely influenced by biomechanical factors. Control of these factors prevents mechanical complications, which include fracture of screws, components, or materials veneering the framework. In this study, the impact of length and threads pitch of dental implants on the stress distribution and maximum Von Mises stress in implant-abutment complex and ja...

Purpose This study aimed to examine novel techniques using prototype endodontic obturators obturate a resin-based sealer. Methods Powder-liquid ratios of MetaSEAL Soft were changed obtain suitable root canal sealing, and the physical properties for various powder-liquid analyzed according ISO-6876. Tensile bond strength was also examined. Prototype with combination thread numbers pitch angles s...
