OBJECTIVES The aim of the present study was to evaluate the cutting efficiency of two new reciprocating instruments, Twisted File Adaptive and WaveOne Primary. MATERIAL AND METHODS 10 new Twisted File Adaptive (TF Adaptive) (SybronEndo, Glendora, CA, USA) and 10 new WaveOne Primary files (Dentsply Maillefer, Ballaigues, Switzerland) were activated using a torque-controlled motor, respectively...

Windows are a significant path for structure-borne and air-borne noise transmission into aircraft. To improve the acoustical performance, damped windows were fabricated using two or three layers of plexiglas with transparent viscoelastic damping material sandwiched between the layers. In this paper, numerical and experimental results are used to evaluate the acoustic benefits of damped windows....

Mass production is an important co mponent of any pest or vector control program that requires the release of large number of insects. As part of efforts to develop an area-wide program involving the sterile insect technique (SIT) for the control of mosquitoes, the Insect Pest Control Laboratory of the Food and Agriculture Organization-International Atomic Energy Agency (FAO-IAEA Joint Division...

Baited pesticide-treated biodegradable spheres were evaluated for their efÞcacy to control and monitor apple maggot, Rhagoletis pomonella (Walsh), and blueberry maggot, R. mendax Curran, ßies. A Plexiglas pane treated with sprayable Tangle-Trap was found to be an effective technique for assessing the fate of Rhagoletis ßies encountering treated spheres. SigniÞcantly more R. pomonella and R. men...

In this study, we describe the design of a tactile sensor based on polyvinylidene fluoride (PVDF). The sensor exhibits high force sensitivity and linearity. This sensor is integrated with an endoscopic grasper tool and can be used in minimally invasive surgeries. It consists of three distinct layers. A rigid micro-machined tooth-like silicon constitutes the top layer of the grasper, and the Ple...
