BACKGROUND To measure the effectiveness of procedural video compared to live demonstration in transferring skills for fabricating orthodontic Adam's Clasp. MATERIALS AND METHODS Forty-nine fourth-year undergraduate male dental students were randomly assigned to two groups. The students in group A (n = 26) attended a live demonstration performed by one faculty, while students in group B (n = 2...

JCO/FEBRUARY 2010 © 2010 JCO, Inc. T venerable Hawley retainer has been basically unaltered in form and application since its introduction to the specialty nearly 100 years ago.1 To add to its utility, we suggest a modification of the retentive clasping mechanism. Although we prefer to use ball clasps rather than Adams clasps because of their sturdiness and simplicity, they are shorter and thus...

Laser tube bending is a flexible forming process. Two irradiation methods of axial and circumferential scanning are generally used to form metal tubes. The two most important disadvantages of circumferential scanning are its lower bending angle and the time interval required between each scan for cooling purpose. In this research, a novel cooling strategy during laser tube bending with circumfe...

Abstract The intensity and the linear scattering polarization profiles of hydrogen Ly α line encode valuable information on thermodynamic magnetic structure upper layers solar chromosphere. Chromospheric Lyman-Alpha Spectro-Polarimeter (CLASP) sounding rocket experiment provided unprecedented spectropolarimetric data this line, as well two-dimensional broadband images in polarization. We theore...

The ability to accurately and effectively predict the interaction between proteins and small drug-like compounds has long intrigued researchers for pedagogic, humanitarian and economic reasons. Protein docking methods (AutoDock, GOLD, DOCK, FlexX and Glide to name a few) rank a large number of possible conformations of protein-ligand complexes using fast algorithms. Previously, it has been show...

The sexual clasp as a reticularly controlled behavior in the toad, Bufo arenarum Ifensel. PHYSIOL. BEUAV. 7 (2) 157-160, 1971.-The motor effects of serial transections of the neuraxis as well as mechanically or electrically produced lesions restricted to different levels of the bulbo-mesencephalic tegmentum were studied in the toad. Complete transection of the brain stem at every level from the...

For some computational problems (e.g., product configuration, planning, diagnosis, query answering, phylogeny reconstruction) computing a set of similar/diverse solutions may be desirable for better decision-making. With this motivation, we have studied several decision/optimization versions of this problem in the context of Answer Set Programming (ASP), analyzed their computational complexity,...

Abstract Among the knots that are connected sum of two torus with cobordism distance 1, we characterise those have 4-dimensional clasp number at least 2, and show their n -fold self-sum has 2 . Our proof works in topological category. To contrast this, build a family topologically slice for which 4-ball genus
