Differences in Cyclic Fatigue Resistance between ProTaper Next and ProTaper Universal Instruments at Different Levels

Journal of Endodontics, 2014
INTRODUCTION: New designs and alloys have been developed to increase cyclic fatigue (CF) resistance of rotary files. The aim of this study was to compare CF resistance of ProTaper Universal (PTU; Dentsply Tulsa Dental, Tulsa, OK) and ProTaper Next (PTN ...

Tranylcypromine in depression resistant to cyclic antidepressions

Progress in Neuro-Psychopharmacology and Biological Psychiatry, 1989
1. Non-responders to cyclic antidepressants were treated with the MAO-inhibitor tranylcypromine in two studies: the first study in an open comparison with L-5-hydroxytryptophan (L-5HTP), the second study in a double blind comparison with nomifensine. 2.

Cyclic Oxidation of Heat Resisting Steels

Oxidation of Metals, 2005
Standard cast, heat resisting steels containing 25–29 w/o (weight percent) chromium and 30–36 w/o nickel together with cast alloys containing 45 or 60 w/o nickel plus low levels of aluminium were subjected to cyclic oxidation in air at 1000 and 1150°C.

Cyclic strain resistance and cyclic fracture behaviour of 2124 aluminium alloy

International Journal of Fatigue, 1993
Abstract In this paper, the cyclic strain resistance and cyclic fracture behaviour of aluminium alloy 2124 are examined. Test specimens of the alloy were cycled using tension-compression loading, under total strain control, over a range of plastic strains giving less than 10 4 cycles to failure. The alloy displayed hardening in both the longitudinal

Complete characterization of channel-resistant DMT with cyclic prefix

IEEE Signal Processing Letters, 2003
We provide a complete characterization of discrete multitone transmission (DMT) systems that employ a cyclic prefix redundancy and that can be equalized by a bank of one-tap equalizers in each subchannel, for almost all values of channel parameters. We show that among all possible finite-impulse response transmitting and receiving filters of arbitrary ...

Electrical resistivity of cyclically deformed tungsten

Scripta Metallurgica, 1977
Resistometric studies on powder metallurgical tungsten wires cyclically deformed by torsion at room temperature are reported. In spite of the quite high crack propagation rate in tungsten, the concentration of fatigue induced lattice defects is shown to be comparable in tungsten and copper. (GHT)

Enterococcal resistance to vancomycin and related cyclic glycopeptide antibiotics

European Journal of Clinical Microbiology & Infectious Diseases, 1990
Enterococci belonging to various species resistant to vancomycin and related cyclic glycopeptide antibiotics have been isolated from hospitalized patients in France, the UK and the USA. All such strains examined display inducible synthesis of a membrane protein associated with resistance.

Cyclic Shear Resistance of Noncohesive Soils

Journal of the Geotechnical Engineering Division, 1980
The cyclic shear resistance of anisotropically consolidated soil is examined with the aid of stress path vecotors in a \ip-\iq stress diagram. It is shown that the current definition of full or 100% pore-pressure ratio is adequate only for conditions of isotropic consolidation.

Resistance of Sand to Cyclic Loading

1996
Abstract Prior to shaking by an earthquake, an element of saturated soil under level ground has undergone a long-term consolidation process under Ko conditions. This soil element is subjected undrained to a sequence of shear stress cycles during an earthquake as illustrated in Fig. 10.l(a).
