1. A review on the ceramic additive manufacturing technologies and availability of equipment and materials
Abstract Ceramic additive manufacturing allows the fabrication of small series of complex parts without the high costs of molds usually associated with traditional ceramic processing. Although research into ceramic 3D printing by all technologies started back in the 90s, its industrial application is still quite restricted when compared to polymers and metal

2. Novel Design of a Hybrid Superconducting Fault Current Limiter with Controlled Solid-State Device
Abstract Fault current limiters are essential devices used to protect the power system and its equipment against high levels of fault current, which are growing up due to the increase of new power sources. This paper proposes a novel design of a Hybrid Superconducting Fault Current Limiter (Hybrid SFCL), which is composed basically by thyristors in series wi

3. Characterization and Comparative Analysis of Corrosion Resistance of 4 High Manganese Steels Models in Aqueous Solution of NaCl
The liquefied natural gas volumes that currently need to be stored and/or transported require engineering to consistently develop materials that combine high mechanical strength and low manufacturing costs. The present work brings the study of four models of high manganese steels (non-commercials), to demonstrate the feasibility of being used in the petroche

4. The WHO strategy for prevention and control of snakebite envenoming: a sub-Saharan Africa plan
Abstract Snakebite is a critical public health issue in tropical countries, particularly in Africa, where 20% of snakebites globally occur. In 2017, the WHO added snakebite envenoming to the category A of neglected tropical diseases. In 2019, thanks to broad institutional and international NGO support, including strong mobilization of African experts and gov

9. Concreto com borracha de recauchutagem de pneu para uso em pavimentação de baixo tráfego
RESUMO O aumento da demanda por veículos acarreta maior produção de novos pneus. No entanto, após o término de sua vida útil, eles se tornam um passivo ambiental de difícil descarte adequado, tanto pela demora em se decompor quanto por seu grande volume. Sua disposição inadequada causa grandes danos ao meio ambiente e favorece a proliferação de ve
