"Attaching crimpable hooks: An easy way out"

Properties of crimpable archwire hooks: a laboratory investigation.

The aim of the present study was to utilize a strain gauge, which enabled the force applied to produce firmly attached crimpable hooks to rectangular stainless steel arch wires, to be measured. In vitro testing of two hooks, American Orthodontic (AO) and TP Orthodontic (TP), and two dimensions of stainless steel archwire, 0.019 x 0.025 and 0.018 x 0.025-inch, was carried out using an Instron Un...

No Easy Way Out (Or in)

In retrospect, when Jardetzky (1966) published a " simple allosteric model for membrane pumps, " he initiated a conceptual movement away from the (then still) prevailing anthropomorphic view of transporters and pumps as " carriers " in the literal sense, membrane-bound entities that somehow made their way across the membrane, loaded with cargo. The idea of an " alternating access " model (as it...

AutoFlow: an easy way to build workflows

Many bioinformatics tasks require the use of different software, making workflows a current need in this research field. There are workflow builders that usually try to simplify the interface disregarding a complex use. This may lead to a non-scalability limitation, or the dependence on the facilities available. Here it is presented AutoFlow, a workflow builder that can handle most computer sys...

Taking the Easy Way Out: How the GED Testing Program Induces Students to Drop Out.

The option to obtain a General Education Development (GED) certificate changes the incentives facing high school students. This paper evaluates the effect of three different GED policy innovations on high school graduation rates. A six point decrease in the GED pass rate due to an increase in passing standards produced a 1.3 point decline in overall dropout rates. The introduction of a GED cert...
