Torquemeter is a transducer for measuring rotational force and converting it into electronic output signal. In this paper, the techniques to fabricate low cost yet effective torquemeter system introduced. The device calibrated tested prove effectiveness robustness. Thesystem developed investigate thetorquegeneratedbywind turbinesystem.The presented comprisesof two subsystemsnamely photointerrup...

The purpose of this work was to study the influence of screw length and bone thickness on the stability of temporary implants. A total of 96 self-drilling temporary screws with two different lengths were inserted into polyurethane blocks (n = 66), bovine femurs (n = 18) and rabbit tibia (n = 12) with different cortical thicknesses (1 to 8 mm). Screws insertion in polyurethane blocks was assiste...

Surface treatment interferes with the primary stability of dental implants because it promotes a chemical and micromorphological change on the surface and thus stimulates osseointegration. This study aimed to evaluate the effects of different surface treatments on primary stability by analyzing insertion torque (IT) and pullout force (PF). Eight samples of implants with different surface treatm...

BACKGROUND As one of the loads applied in implant dentistry, managing the torque is important for the success of an implant treatment. For this purpose, it is crucial to ascertain the level of torque being exerted with a hand driver. We have developed an adapter that makes it easy to measure torque by using a standard torque wrench in one's possession, rather than with a torquemeter. PROCEDUR...

The fluid mixing process is a common supportive phenomenon that often occurs in large number of industrial systems. This the subject many numerical and experimental analysis. effectiveness depends on: tank construction, phases viscosity, temperature, density liquids and, what crucial, impeller shape. optimal design geometry still an open issue. In this research work, main objective investigatio...

We built up an experiment to study liquid-liquid dispersions in a turbulent Taylor-Couette flow, produced between two counterrotating coaxial cylinders, of radii ri = 100mm and ro = 110mm (gap ratio η = ri/ro = 0.909). The useful length is L = 185mm. There is a space of 10mm between the cylinders bottom ends and a free surface on the top. The cylinders rotation rates ωi and ωo can be set indepe...
