the aim of this research is to investigate the effect of carbon fiber reinforced polymer (cfrp) composite fabric on monotonic and fatigue behaviors of reinforced concrete beams. to control the failure occurrence, a small notch was induced at the middle span in bottom surface for all of the studied rc specimens. totally 12 beams were tested from which 6 beams tested under monotonic and 6 other t...

OBJECTIVES The aim of this study was to evaluate the sealing ability of lateral compaction and tapered single cone gutta-percha techniques in root canals prepared with stainless steel and rotary nickel titanium root canal instruments by fluid filtration method. STUDY DESIGN The root canals were prepared with stainless steel (SS) and nickel titanium (NiTi) instruments. The canals prepared with...

Nulling interferometry is one of the most promising technologies for imaging exoplanets within stellar habitable zones. The use photonics carrying out nulling enables contrast and separation required exoplanet detection. So far, two key issues limiting current-generation photonic nullers have been identified: phase variations chromaticity beam combiner. tricouplers addresses both limitations, d...

PURPOSE To study the clinical/radiographic outcomes and stability of a tapered implant design with a hydrophilic surface when placed in the maxilla using various protocols and followed for one year. METHODS Ninety-seven consecutive patients treated as part of daily routine in two clinics with 163 tapered implants in healed sites, in extraction sockets and together with bone augmentation proce...

Microfabricated tapered pits in vivo can stimulate connective tissue and bone attachment to percutaneous devices, secondarily preventing epithelial migration, and promoting long-term implant survival. Epithelial cells, which form a seal with a dental implant, acting as a barrier, and osteoblasts, which form bone, can come into contact with the same implant topography. To investigate whether the...

in order to investigate the flexural behaviors of rc beams after freeze-thaw cycles, compressive strength test of concrete cubes after 0, 50, 100, 125 freeze-thaw cycles were made, and static flexural experiment of 48 rc beams after 0, 50, 100, 125 freeze-thaw cycles were made. the relationships of relative compressive strength, mass loss rate, relative dynamic elastic modulus and numbers of fr...

OBJECTIVE To compare the clinical soft tissue responses around implant tooth-supported 3-unit bridges using tapered abutments with those using butt-joint abutments. METHODS In a split-mouth design study, 8 mm Ankylos (Dentsply Friadent, Germany) implants were placed in the second mandibular molar region of 8 adult Macaca fascicularis monkeys about 1 month after extraction of all mandibular mo...
