1. Heat treatment analysis of ASTM A106 steel spheroidization and erosive wear at high temperatures
Abstract The microstructures of steels are altered when exposed to high working temperatures for long periods, which results in varied physical and chemical proprieties. This study evaluates the erosive wear behavior of ASTM A106 steel after it is exposed to high temperatures for long durations. Samples of normalized ASTM A106GrB steel were placed in a muffl

2. Análise da desinfecção apical do canal radicular preparado em três diferentes comprimentos de trabalho, utilizando movimento rotatório contínuo ou reciprocante e duas substâncias irrigadoras: estudo in vitro
Resumo Introdução O preparo do canal radicular, em especial o terço apical, é fundamental para o sucesso da terapia endodôntica, pois abriga o forame radicular, local que comunica o endodonto com os tecidos perirradiculares. Objetivo A presente pesquisa avaliou a contaminação do terço apical após a instrumentação de canais radiculares em três c

3. DEVELOPMENT OF INEXPENSIVE CELLULOSE-BASED SORBENTS FOR CARBON DIOXIDE
ABSTRACT Aqueous amine solutions are benchmark solvents for CO2 capture and their operational drawbacks are well-known. In order to overcome these problems, the support of amines on solid materials appears as an option for CO2 capture. Cellulose is a versatile and low-cost material that can be used as a support. This study reports chemical modification of ce

4. Effect of cold-working process on cyclic deformation of electrolytic copper
Abstract Cyclic softening and hardening processes are expressed by the change in the stress amplitude necessary to cause a given strain amplitude. Understanding the cyclic stress-strain behavior of materials is an important step in the complex study of their fatigue behavior. The potential differences between the defect structures of cold-formed materials ma

10. Acondicionamiento del gas inhalado en pacientes con vía aérea artificial. Revisión narrativa
ABSTRACT Instrumentation of the airways in critical patients (endotracheal tube or tracheostomy cannula) prevents them from performing their function of humidify and heating the inhaled gas. In addition, the administration of cold and dry medical gases and the high flows that patients experience during invasive and non-invasive mechanical ventilation generat

11. SHIFTS AND HARVESTING SYSTEMS ON QUALITY OF IMPURITIES SAMPLES IN SUGARCANE
ABSTRACT Semi-mechanical and mechanical harvesting methods may influence the content of impurities in harvested sugarcane. This study aimed to evaluate the quality of three mechanical methods of sugarcane harvesting: one semi-mechanical, and two mechanical ones - self-performed and outsourced, during three working shifts. As quality indicators, both mineral

12. Mechanical and microstructural behavior evolution of non-ferrous metals by ECASD
ABSTRACT In this study, Equal-Channel Angular Sheet Drawing- ECASD with a die set at 135° was used to produce plastic deformation onto an aluminum alloy AA-1100-O and a magnesium alloy AZ31-O samples, expecting a decreasing the grain size in order to increase the plasticity of these alloys under certain specific working conditions. In this study, the micros
