Histological evaluation of the cleaning effectiveness of two reciprocating single-file systems in severely curved root canals: Reciproc versus waveOne
(2015-01-01)
Objective: The aim of this study was to evaluate the cleaning effectiveness achieved with two reciprocating single-file systems in severely curved root canals: Reciproc and WaveOne. Materials and Methods: Twenty-five mesial ...
Trust and reciprocity: A theoretical distinction of the sources of social capital
(SAGE PUBLICATIONS LTD, 2011)
The social capital literature has focused on the functional and structural properties of social relations, partially neglecting the way in which they are experienced by individuals. Drawing on anthropological and social ...
Irreducibility criteria for reciprocal polynomials and applications
(Mathematical Association of America, 2017-01)
We present criteria for determining irreducibility of reciprocal polynomials over the field of rational numbers. We also obtain some combinatorial results concerning the irreducibility of reciprocal polynomials. As a ...
Comparison of cyclic fatigue and torsional resistance in reciprocating single-file systems and continuous rotary instrumentation systems
(Nihon Univ, School Dentistry, 2014-12-01)
As compared with continuous rotary systems, reciprocating motion is believed to increase the fatigue resistance of NiTi instruments. We compared the cyclic fatigue and torsional resistance of reciprocating single-file ...
A game-theoretic model of reciprocity and trust that incorporates personality traits
(2019)
We propose a game-theoretic model of reciprocity and trust that incorporates personality traits. In the model, positive and negative reciprocity are “reciprocal preferences:” parameters of heterogeneous utility functions ...
Direct reciprocity in animals: The roles of bonding and affective processes
(Wiley, 2017-04)
The presence of direct reciprocity in animals is a debated topic, because, despite its evolutionary plausibility, it isbelieved to be uncommon. Some authors claim that stable reciprocal exchanges require sophisticated ...
Some properties of classes of real self-reciprocal polynomials
(2016-01-01)
The purpose of this paper is twofold. Firstly we investigate the distribution, simplicity and monotonicity of the zeros around the unit circle and real line of the real self-reciprocal polynomials Rn(λ)(z)=1+λ(z+z2+...+zn-1)+zn, ...
Effectiveness of reciproc and MTwo for removing filling material during root canal retreatment using a digital radiograph system
(2018-01-01)
Objective: To compare the efficacy of Reciproc (reciprocating) and MTwo (rotary) in the filling material removal during endodontic retreatment. Methods: Thirty simulated root canals (plastic blocks) were prepared and filled. ...
Fruit quality and DNA methylation are affected by parental order in reciprocal crosses of tomato
(Springer, 2020-10)
Crosses between different genotypes and even between different species arecommonly used in plant breeding programs. Reciprocal hybrids are obtained bychanging the cross direction (or the sexual role) of parental genotypes ...
