1. Mix design formulation range for metakaolin-based geopolymer synthesis
Abstract This article presents a range of mix design formulations to obtain metakaolin-based geopolymer synthesis. Geopolymer samples were synthesized from metakaolin, a 10 M sodium hydroxide solution, and alkaline sodium silicate. These three components were mixed in different proportions to form a paste which was molded in a cylindrical shape, set at room

2. Is there a relationship between tonsil volume and the success of pharyngeal surgery among adult patients with obstructive sleep apnea?
Abstract Objectives: Hypertrophic palatine tonsils play a role in the blockage of the upper airway, one of the known causes of Obstructive Sleep Apnea (OSA). Therefore, it is possible that there is an association between tonsil size and the success of pharyngeal surgery during OSA treatment. The main objective of this study was to evaluate the relationship

5. Elaboration of an instrument to evaluate the recognition of Brazilian melodies in children
Resumo Introdução: Há evidências que apontam para a importância da avaliação da percepção musical através de instrumentos objetivos e subjetivos. No Brasil, há escassez de instrumentos que avaliem a percepção musical. Objetivo: Desenvolver um instrumento para avaliar o reconhecimento de melodias tradicionais brasileiras e investigar o desempen

6. Respostas Emocionais de Médicos aos Estímulos Afetivos do International Affective Picture System (IAPS)
RESUMO As emoções dos médicos têm um papel importante na relação com o paciente, pois podem interferir em suas atitudes, percepções e nos processos de julgamento e decisão. O objetivo desta pesquisa foi analisar a resposta emocional dos médicos aos estímulos do International Affective Picture System (IAPS). Este estudo utilizou o método quantitat

7. Development and application of a flexible numerical model to evaluate the safety of room-and-pillar mines
Abstract The design of room-and-pillar mines relies on the correct estimation of the safety indicator of the underground structures formed by the excavation of drifts. Thus, the study of the geomechanical behavior is of vital importance. The mathematical models play an important role in the identification of problematic areas and allows different configurati

8. Frege’s Puzzle on the Santa Monica Beach De Jure Co-reference and the Logical Appraisal of Rational Agents
ABSTRACT In this paper, I argue that a number of influential Millian responses to Frege’s puzzle, which consist in denying that Frege’s data apply to natural languages (and thinking), are not viable if logic is to play its role in legitimizing the logical appraisal of rational subjects. A notion of validity which does justice to the normativity of logic

9. Numerical analysis of the liquid ejection due to the gaseous jet impact through computational fluid dynamics
Abstract Metal droplets generated by an impinging jet, play an important role in metal refining processes, mainly in oxygen steelmaking, where the droplets are ejected into the slag phase. Since the available interfacial area of droplets is very high in this process, the generated droplets enhance the rates of heat transfer and chemical reactions. Therefore,

10. The Role that Electrolytes Play in the Synthesis of Water-Soluble CdTe Quantum Dots Prepared at Ambient Temperature
In this work, we have synthesized CdTe quantum dots (QDs) dispersed in an aqueous medium at ambient temperature, and investigated their optical properties. Synthesis of CdTe QDs in the presence of simple amines removed the need for an additional energy source and inert atmosphere, in a simple and inexpensive experimental setup. The use of ammonia or hydrazin

11. Geschichte, Geschichten und Mythen in Dea Lohers Olgas Raum
Abstract Over the past few decades, Germany's division and subsequent unification have altered he way the country's history is understood, with Eastern and Western narratives needing to merge into a new master narrative. The different accounts of the life and death of the Jewish-German communist Olga Benario, partner of the Brazilian freedom fighter, Luis Ca

12. Is the difference in the volume of the pharyngeal space, as measured by acoustic pharyngometry, before and after tonsillectomy proportional to the volume of the excised tonsils?
OBJECTIVE: Adenotonsillectomy is recognized as an effective therapy for snoring and sleep disorders in children. It is important to understand whether adenotonsillectomy significantly increases the volume of the pharyngeal space. The goal of this study was to evaluate the change in oropharyngeal volume after adenotonsillectomy and the correlation of this ch
