The purpose of this study was to retrospectively compare the treatment times of Class II division 1 malocclusion subjects treated with four first premolar extractions or a non- extraction protocol and fixed edgewise ...
Describing all bi-orderings on Thompson’s group F
We describe all possible ways of bi-ordering Thompson’s group F: its space of bi-orderings is made up of eight isolated points and four canonical copies of the Cantor set.

Cohomology and graded Witt group kernels for extensions of degree four in characteristic two
In earlier work the authors determined the graded Witt kernel GW(q)(E/F) = ker(GW(q)F -> GW(q)E) when E/F is a biquadratic extension in characteristic 2 by calculating the cohomological kernel H-2*(E/F) = ker(H-2*F -> ...
Synthesis of New Pentaerythritol-Based Gemini Surfactants
(Georg Thieme Verlag Kg, 2001-06)
New dimeric or gemini surfactants bearing double-chain with two or four sulfonate groups, and quadruple-chain with four sulfonate groups, were prepared from pentaerythritol in good overall yields. All these surfactants ...
Bioacoustics of four Scinax species and a review of acoustic traits in the Scinax catharinae species group (Amphibia: Anura: Hylidae)
(Deutsche Gesellschaft Herpetologie Terrarienkunde E V, 2017-05-15)
Herein, we present new data on the acoustic repertories of Scinax heyeri, S. humilis, S. longilineus, and S. trapicheiroi, all of which are species belonging to the S. catharinae species group. Based on the acoustic features ...
Oxalic acid under adhesive restorations as a means to reduce dentin sensitivity: A four-month clinical trial
The aim of this double-blind randomized controlled clinical trial was to evaluate the reduction of dentin sensitivity using an oxalatebased compound, placed under adhesive restorations, during a four-month period. One ...
Genetic markers in four coastal Chilean locations Poblaciones costeras de Chile: Marcadores genéticos en cuatro localidades
Background: Historical and anthropological data suggest the presence of descendents of Changos, Cuncos, Chonos and Yamanas, South American indian populations, in certain Chilean coastal villages. Aim: To assess the degree ...
