GEOPOLYMER CEMENT MADE FROM RECYCLED GLASS AND ITS MANUFACTURING PROCESS, the present invention relates to a geopolymer cement from recycled glass and its manufacturing process that, according to its characteristics, can produce geopolymer cement in its own and specific binding structure of a rigid solid type, made from recycled glass (waste), alkalis and water, and obtained directly by milling, homogenization, alkalinization and curing at room temperature, or forced curing of its components, and it can be used, in an extremely convenient, safe and cost-effective manner, as a new geopolymer matrix to replace the traditional ones made from metakaolin, blast furnace slag, fly ash or volcanic rock in various applications - to manufacture cement slabs, concrete, fiber composites and materials for coatings, aligned with an eco-friendly concept for complete reuse of this waste which is disposed in the environment.

In this paper we extend to asymmetric quantum error-correcting codes the construction methods, namely: puncturing, extending, expanding, direct sum and the (u|u +v) construction. By applying these methods, several families of asymmetric quantum codes can be constructed. Consequently, as an example of application of quantum code expansion developed here, new families of asymmetric quantum codes derived from generalized Reed-Muller codes, quadratic residue, Bose-Chaudhuri-Hocquenghem, character codes and affine-invariant codes are constructed. © 2013 Springer Science+Business Media New York.

The authors conducted a study to evaluate tooth sensitivity (TS) and the bleaching effectiveness associated with use of a calcium-containing (CC) in-office bleaching gel. The authors used a 35 percent calcium-free (CF) hydrogen peroxide gel and a 35 percent CC hydrogen peroxide gel according to the manufacturer's instructions in 40 caries-free participants 18 years or older. They performed two bleaching sessions with a one-week interval between sessions. The authors registered the color at baseline and after the first and second bleaching sessions by using a shade guide and by gauging the participant's perception of TS as registered on a scale from 0 (none) to 4 (severe). The authors evaluated the bleaching effectiveness at each week's recall visit by means of the Friedman test, and they compared the groups at each assessment point by means of the Mann-Whitney test. They evaluated the percentage of participants with TS and the intensity of the TS by using the Fisher exact and Mann-Whitney tests. Both groups demonstrated equivalent and significant tooth color enhancement compared with color values at baseline (P < .05), with an average bleaching of 7 to 8 shade guide units. Most of the participants from the CF group (80 percent) experienced sensitivity while undergoing the bleaching regimen, whereas only 40 percent of participants from the CC group reported experiencing TS (P = .02). The intensity of TS was significantly higher (P < .01) for the CF group during in-office dental bleaching. The CC 35 percent hydrogen peroxide gel reduced the TS during in-office dental bleaching without jeopardizing the bleaching effectiveness. The results of this study support the findings that a CC 35 percent hydrogen peroxide gel can reduce TS during in-office dental bleaching.

In this Letter we study the Aharonov-Bohm problem for a spin-1/2 particle in the quantum deformed framework generated by the κ-Poincaré-Hopf algebra. We consider the nonrelativistic limit of the κ-deformed Dirac equation and use the spin-dependent term to impose an upper bound on the magnitude of the deformation parameter ε. By using the self-adjoint extension approach, we examine the scattering and bound state scenarios. After obtaining the scattering phase shift and the S-matrix, the bound states energies are obtained by analyzing the pole structure of the latter. Using a recently developed general regularization prescription [Phys. Rev. D. 85 (2012) 041701(R)], the self-adjoint extension parameter is determined in terms of the physics of the problem. For last, we analyze the problem of helicity conservation. © 2013 Elsevier B.V.

Four quantum code constructions generating several new families of good nonbinary quantum nonprimitive nonnarrow-sense, Bose-Chaudhuri-Hocquenghem codes, are presented in this paper. The first two are based on Calderbank-Shor-Steane (CSS) construction derived from two nonprimitive Bose-Chaudhuri-Hocquenghem codes. The third one is based on Steane's enlargement of nonbinary CSS codes applied to suitable subfamilies of nonprimitive nonnarrow-sense Bose-Chaudhuri-Hocquenghem codes. The fourth construction is derived from suitable subfamilies of Hermitian dual-containing nonprimitive nonnarrow-sense Bose-Chaudhuri-Hocquenghem codes. These constructions generate new families of quantum codes whose parameters are better than the ones available in the literature. © 2014 IEEE.

Several new families of multi-memory classical convolutional Bose-Chaudhuri-Hocquenghem codes as well as families of unit-memory quantum convolutional codes are constructed in this paper. Our unit-memory classical and quantum convolutional codes are optimal in the sense that they attain the classical (quantum) generalized Singleton bound. The constructions presented in this paper are performed algebraically and not by computational search. © 2012 IEEE.

Two new families of asymmetric quantum codes are constructed in this paper. The first one is derived from the Calderbank-Shor-Steane (CSS) construction applied to classical Reed-Solomon (RS) codes, providing quantum codes with parameters [[N = l(q l - 1), K = l(q l -2d + c+1),d z ≥ d/d x ≥ (d - c)]] q, whereq is a prime power and d > c + 1, c ≥ 1, l ≥ 1 are integers. The second family is derived from the CSS construction applied to classical generalized RS codes, generating quantum codes with parameters [[N = mn, K = m(2k-n+c), d z ≥ d/d x ≥ (d - c)]]q, where q is a prime power, 1 < k < n < 2k + c ≤q m,k = n-d+1, and n, d > c+1, c ≥ 1, m ≥ 1 are integers. Although the second proposed construction generalizes the first one, the techniques developed in both constructions are slightly different. These new codes have parameters better than or comparable to the ones available in the literature. Additionally, the proposed codes can be utilized in quantum channels having great asymmetry, that is, quantum channels in which the probability of occurrence of phase-shift errors is large when compared to the probability of occurrence of qudit-flip errors. © 2011 Springer Science+Business Media, LLC.
