CONSIDERAÇÕES SOBRE MEMÓRIA E MORTE DO IMPERADOR JULIANO NOS TESTEMUNHOS DE LIBÂNIO E AMIANO MARCELINO (SÉCULO IV d.C.)
RESUMO Dentre os vários temas que tratam sobre o Imperador Juliano, o assunto sobre a sua morte chamou nossa atenção. Vários autores da Antiguidade Tardia, cristãos ou não cristãos, forneceram várias versões sobre tal acontecimento. O sofista Libânio e o militar Amiano Marcelino registraram cenas relevantes da morte do Príncipe, redigiram seus textos na mesma época, eram antioquianos e provavelmente, se comunicavam. Porém, suas narrativas sobre a morte de Juliano se diferenciam. Portanto, temos como objetivo analisar as diversas mortes do Imperador Juliano apresentadas nos testemunhos de Libânio, assim como realizar a comparação desses relatos com o testemunho de Amiano Marcelino sobre o mesmo tema. A comparação servirá para termos uma melhor compreensão acerca da maneira como o sofista e o militar construíram uma memória virtuosa desse Imperador, transformando a morte daquele Príncipe em uma memória viva. Acrescentamos que os dois autores redigiram seus textos no período do Imperador Teodósio I. Logo, temos como hipótese que as diversas versões sobre a morte de Juliano estão relacionadas com eventos que permeiam os momentos da escrita das narrativas da morte. Dessa maneira, os autores tornam viva a memória sobre Juliano através dos vários relatos sobre o acontecimento fúnebre

Interactions between chloride and cement-paste materials
International audienceThe durability of cement-based materials with respect to exterior aggressions is one of the current priorities in civil engineering. Depending on their use, the cement-based materials can be exposed to different types of aggressive environments. For instance, damages to concrete structures in contact with a saline environment (sea water on bridges, deicing salts on roads, etc.) are of utmost importance. Upon exposure to saline water, Cl À ions penetrate into the structures and subsequently lead to reinforcement corrosion. Chloride attack is often combined with other aggressive influences such as temperature (e.g., freezing) or the ingress of other ions (e.g., sulfates in sea water). We therefore aim to explore the effect of sodium chloride (NaCl) on the structural chemistry of cement paste. Existing studies about reinforcement corrosion by chloride have focused on the penetration of Cl À ions and the comparison between bfreeQ ions (water-soluble ions) and bound ones. However, little is known about the fixation mechanisms, the localization of Cl in the cement matrix and the structural interaction between Cl and the silicate and aluminate hydrate phases present in cement paste. We present here results of a multinuclear nuclear magnetic resonance study on the fixation of chloride in the hydration products and the characterization of new phases potentially appearing due to chloride ingress.
