1. The Concept of a Rupture Risk Envelope for the Cochleo-Saccular Membranes
Abstract Introduction Alterations in endolymphatic pressure have long been suspected of being associated with the development of endolymphatic hydrops and rupture of the membranous labyrinth. More recently, there has been a focus on how membrane mechanics might contribute to membrane rupture. This is suspected to involve the viscoelastoplastic properties of

3. Faith-based intervention, change of religiosity, and abstinence of substance addicts
Objective: To investigate the effects of developing religiosity on abstinence of substance abuse among recovering addicts in a faith-based and a secular-based treatment program. Methods: Religiosity of recovering addicts was measured using the 38-item Brief Multidimensional Measure of Religiousness/Spirituality at three points in time: at initiation of subs

4. First-Principles Calculations of a New Semi-Conductive Carbon Allotrope Named ABF-Carbon
Carbon is an extremely versatile element and can generate a plethora of structures with distinct properties. Proposing new possible metastable allotropic structures for carbon has been the subject of increasing interest over the past few years. In this contribution, we present a new carbon allotrope, named ABF-Carbon, based on the connection of spiropentadie

5. THEORETICAL STUDIES ON DIACETONEDIPEROXIDE DERIVATIVES AND COMPARISONS WITH OTHER MULTI-PEROXIDIC COMPOUNDS
Diacetonediperoxide (DADP) derivatives were investigated with density functional theory (DFT) methods at the DFT-B3LYP and M06-2X/6-311++G (d, p) levels and were also compared with other multi-peroxidic compounds. The investigated derivatives were 3,6-dimethyl-3,6-diamine-1,2,4,5-tetraoxane (DADPNH2), 3,6-dimethyl-3,6-dinitro-1,2,4,5-tetraoxane (DADPNO2), an

7. Nonlinear numerical analysis of composite slabs with steel decking
Resumo O comportamento das lajes mistas é governado pelo cisalhamento longitudinal na interface entre o aço e o concreto, que é desenvolvido em lajes sob flexão simples. O método m-k e o método da interação parcial, utilizados no cálculo da resistência ao cisalhamento na interface aço-concreto de lajes mistas, são baseados em ensaios experimentai

8. Recrystallization Kinetics of Fe-3%Si after Deformation at High Strain Rate and High Temperature
Recrystallization kinetics of Fe-3%Si with initial grain size 296~839µm at the temperature range 1223~1423K, strain range from 0.51 to 0.92, strain rate range 5~80s−1 was studied by isothermal compression test using Gleeble-2000. The effect of strain, strain rate, initial grain size and annealing temperature on the recrystallization kinetics were discusse

10. CATECISMO DO CIDADÃO: CONSTITUCIONALISMO E SOBERANIA POPULAR EM GUILLAUME DE SAIGE
Trata-se de analisar as linguagens políticas em disputa na definição da soberania – tema caro à teoria política –, no período que antecede a Revolução Francesa, mediante a obra Catecismo do cidadão (Catéchisme du Citoyen) , de Guillaume de Saige. Escrita em 1775 (reeditada em 1787) e banida pelo Parlamento, interpreta-se tal obra (ao lado de ou

11. Chemosensor Development of Cu2+ Recognition Using 1,5-Diphenylthiocarbazone: Optimization, COSMO-RS and DFT Studies
The sensitive and selective chemosensor for copper(II) ions (Cu2+) was successfully optimized using the 1,5-diphenylthiocarbazone (DPT) compound. The result showed that dimethyl sulfoxide (DMSO) in a 9:1 (DMSO:water) ratio at a pH of 3 was the optimum medium for DPT to act as chemosensor of Cu2+ recognition. The DPT chemosensor did not encounter any interfer

12. Reliability analysis of built concrete dam
Resumo O projeto convencional de barragens de gravidade de concreto ainda segue o método determinístico, que não quantifica diretamente o efeito das incertezas na segurança da estrutura. A teoria de confiabilidade estrutural permite a quantificação da segurança destas estruturas, a partir da quantificação das incertezas inerentes aos parâmetros de
