Solitons from dressing in an algebraic approach to the constrained KP hierarchy
(Iop Publishing Ltd, 1998-11-27)
The algebraic matrix hierarchy approach based on affine Lie sl(n) algebras leads to a variety of 1 + 1 soliton equations. By varying the rank of the underlying sl(n) algebra as well as its gradation in the affine setting, ...
Tissue response to experimental dental cements prepared from a modified power glass composition
(Japanese Soc Dental Materials Devices, 2012-07-01)
The present work seeks to evaluate the biocompatibility of experimental glass ionomer cements (GIC) prepared from niobium-calcium fluoro-alumino-silicate glass powder and two commercial GICs. The GICs were implanted into ...
Comparability of results from two leakage models
(Mosby-elsevier, 2008-08-01)
Objective. The goal of this study was to check whether leakage results of the same specimens measured by 2 different leakage models are similar.Study design. Canine root canals were prepared and filled with cold gutta-percha ...
On the number of singularities in generic deformations of map germs
(Oxford University Press, 1998-08-01)
Let f:C-n, 0 --> C-p, 0 be a K-finite map germ, and let i = (i(1),..., i(k)) be a Boardman symbol such that Sigma(i) has codimension n in the corresponding jet space J(k)(n, p). When its iterated successors have codimension ...
A comparison of one versus two appointment endodontic therapy in dogs' teeth with apical periodontitis
(Lippincott Williams & Wilkins, 2003-02-01)
This study was conducted to observe the healing process in dogs' teeth with apical periodontitis after root canal treatment in one or two appointments. Premolars and anterior dogs' teeth had their root canals opened to the ...
The induction of cytotoxicity, oxidative stress, and genotoxicity by root canal sealers in mammalian cells
(Mosby-elsevier, 2009-12-01)
Objective. Toxicologic aspects of the root canal sealers Acroseal, Epiphany, AH Plus, and castor oil polymer (COP) were analyzed using cell culture techniques.Study design. Set materials were extracted in culture medium, ...
Biomonitoring of substrates containing sewage sludge: assessment of the feasibility in using the diplopod Rhinocricus padbergi.
(2012-01-01)
Due to the constant release of potentially harmful substances in the environment, it is necessary the use of biomonitoring as a form to assess the impact of these substances on animals that inhabit this environment. ...
Singular Value Decomposition and Ligand Binding Analysis
(Hindawi Publishing Corporation, 2013-01-01)
Singular values decomposition (SVD) is one of the most important computations in linear algebra because of its vast application for data analysis. It is particularly useful for resolving problems involving least-squares ...
Massive spin-2 theories in arbitrary D>= 3 dimensions
(Elsevier B.V., 2015-03-01)
Here we show that in arbitrary dimensions D >= 3 there are two families of linearized second order Lagrangians describing massive "spin-2" particles via a nonsymmetric rank-2 tensor. They differ from the usual ...
Impact Factor of the journals used by the post-graduation programs in Communication and Information for the propagation of knowledge
(Univ Federal Rio Grande Sul, Fac Biblioteconomia & Comunicacao, 2018-09-01)
The management of scientific policy and its evaluation tools serve to plan and understand scientific dynamics. In this sense, the formulation of a policy for the evaluation of postgraduate courses is fundamental. Considering ...
