1. Physical-mechanical behavior of alkali-activated materials produced by the one-part method based on fly ash and rice husk ash
Abstract The study on the physical-mechanical properties of alkali-activated materials (AAM) produced by the ‘one-part’ method was carried out. For this, residues such as fly ash and rice husk ash (RHA) were used. The alkaline activator (NaOH) was calcined together with RHA for 2 h at 750 °C. Dry mixes were prepared by replacing fly ash with 10%, 20%, a

2. Pressed roofing tile based on cementitious material and basalt powder: Technological and toxicological characterization
Abstract This study aims to develop a pressed concrete roofing tile from powder technology containing basalt powder in substitution of fine sand (aggregate) for application in building covers. Specimens were submitted to technological and toxicological characterization. Hence, pressed specimens based on cement and basalt powder were analyzed. In the bending

3. Use of glass waste in the production of metakaolin-based geopolymer submitted to room temperature and thermal curing
Resumo O metacaulim é a principal matéria-prima utilizada na síntese de geopolímeros, embora a relação entre os teores de sílica e alumina não seja a ideal. Normalmente, o teor de SiO 2 é ajustado com o uso de silicatos presentes na solução ativadora. Uma opção ecoeficiente seria o uso de resíduos de vidro como fonte adicional de sílica. Este

4. 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

5. Probiotic characterization of a commercial starter culture used in the fermentation of sausages
Abstract Probiotic starter culture does not only improve the safety and shelf-life of products but also extends health benefits to the consumer. This study investigated the probiotic potential of a commercial starter culture used in the fermentation of meat sausages. The starter culture tested, composed of Lactobacillus sakei, Staphylococcus xylosus, and Sta

6. Sporotrichosis refractory to conventional treatment: therapeutic success with potassium iodide,
Abstract Sporotrichosis is a subcutaneous mycosis caused by dimorphic fungi of the genus Sporothrix. The authors report a case of fixed cutaneous sporotrichosis with therapeutic failure after 18 months of itraconazole and terbinafine associated with cryosurgery. The patient was cured after the introduction of saturated potassium iodide solution. Sporothrix b

10. Conhecimento do Acadêmico de Medicina sobre Cuidados Paliativos
RESUMO Introdução O envelhecimento da população mundial traz consigo o aumento de doenças crônicas, sem ser acompanhado de melhoria na qualidade de vida ou do enfrentamento das enfermidades. Nesse contexto, os cuidados paliativos se enquadram como um modelo interdisciplinar que visa garantir o cuidado integral ao ser humano. Em contrapartida, a busca

12. A study on the compressive strength and microstructure characteristic of alkali-activated metakaolin cement
ABSTRACT The main purpose of this study was to investigate the compressive strength and microstructure characteristic of alkali-activated metakaolin cement (AAMC). In accordance with this purpose, besides the pure metakaolin activation five other mixtures were designed by substitution of different OPC ratios instead of metakaolin (MK) from 0 to 25 (5, 10, 15
