Numerous studies have investigated the use of waste glass as a partial substitution in Portland cement. Nonetheless, it seems there is no consensus about the influence of particle size and color on the behavior of the compounds. This work investigates the influence of soda-lime glass microparticles on the properties of cement and mortar in both fresh and hardened states. The effects of partial substitution (10 and 20%) of the cement by colorless and amber glass particles with dimensions of approximately 9.5 mm were investigated. The results revealed that the substitutions did not significantly affect the setting times, nor the mechanical properties of mortar at longer curing times. The influence of glass content and chemical composition on workability and hydration heat was also observed. The waste glass samples showed lower thermal diffusivity than the control sample. Thermal emissivity was not influenced by the presence of glass microparticles.
Em 2018, a cineasta Mbya Guarani Patrícia Ferreira Pará Yxapy e a artista visual Sophia Pinheiro realizaram juntas o filme Teko Haxy – ser imperfeita. Trata-se de um trabalho que elabora, a partir de uma escrita epistolar, a relação de intimidade entre as duas mulheres reunidas na aldeia Ko’enju, onde vive Patrícia, no extremo sul do Brasil. Pretendemos abordar a experiência do filme enquanto uma escrita de si entre as duas que envolve implicações em diferentes níveis: da metodologia, da escritura, do processo, das formas fílmicas e da mise-en-scène. Com isso, acreditamos ser possível encontrar um feminismo produzido nas tentativas de aproximação e, também, nos distanciamentos, que atravessam historicamente as relações entre as mulheres indígenas e não indígenas.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
