PURPOSE The aim of this study was to compare the shaping effectiveness rotary nickel-titanium (Profile .04 ISO), ultrasonic (K-Type/Satelec), and stainless-steel hand file (K-file/Maillefer) instrumentation and to assess tubular penetration of 2 gutta percha sealers (AH Plus and Sealite-Ultra) following 4 different final irrigation regimens in primary molar roots. METHODS Distal roots of extr...

OBJECTIVES To present to report the first case of ureteral lithiasis resolved using a new endoscopic approach, which we call microureteroscopy (m-URS) and attempts to reduce the ureteral damage caused by conventional instrumentation. MATERIAL AND METHODS We selected a 53-year-old patient with a 16-mm calculus in the right distal ureter. For endoscopic access, we used a 4.8 Fr sheath from the ...

The Smart Driving Skill Evaluation (SDSE) System presented in this paper expedite the testing of candidates aspiring for a driving license in a more efficient and transparent manner, as compared to the present manual testing procedure existing in most parts of Asia and Pacific region. The manual test procedure is also subjected to multiple limitations like time consuming, costly and heavily con...

introduction: apical transportation changes the physical shape and physiologic environment of the root canal terminus. the aim of the present experimental study was to determine the extent of apical transportation after instrumentation with hand k-flexofile and k3 rotary instruments by means of cone-beam computed tomography (cbct). methods and materials: forty mesiobuccal root canals of maxilla...

TinyAID is a tool that supports automated instrumentation and evaluation of TinyOS-based distributed applications. Two types of instrumentations are provided: logging of call chains and message flows within the network. TinyAID assists the debugging process by post evaluation of the logged data. A main benefit is the visualization component for representing traces in their spatial and temporal ...

Retrospective security has become increasingly important to the theory and practice of cyber security, with auditing a crucial component of it. However, in systems where auditing is used, programs are typically instrumented to generate audit logs using manual, ad-hoc strategies. This is a potential source of error even if log analysis techniques are formal, since the relation of the log itself ...

John Markwell presented a comprehensive review [1] of the second edition of our laboratory manual, Fundamental Laboratory Approaches for Biochemistry and Biotechnology, which we fondly refer to as FLABBe2 ([2]. Markwell’s review was fair and provided valuable information for us to consider in future editions. It should be noted that the experiments in FLABBe2 are designed for laboratories runni...

Most nuclear power plants in operation were built in the 1970’s and 1980’s. Plants of this vintage would require extensive upgrade for the instrumentation and control (I&C) to be able to support plant life extension. The most challenging aspect of I&C upgrades for these plants is the upgrade of the neutron monitoring system (NMS) and the Reactor Manual Control System (RMCS). These are specializ...
