    Microwave-Assisted One-Pot Synthesis of Substituted Tetrahydrocarbazole and 8,9,10,11-Tetrahydro-7H-pyrido[a]carbazoles

    No full text
    One-pot synthesis of one-substituted tetrahydrocarbazole and 4-substituted 8,9,10,11-tetrahydro-7H-pyrido[a]carbazoles from substituted quinolinylhydrazines and cyclohexanone in acetic acid was performed by microwave irradiation in a controlled temperature with simultaneous cooling system in closed vessel. The optimization procedures of process variables, power, temperature, and irradiation time are reported in detail, and the results from microwave processes are compared with conventional ones

    Going Beyond Counting First Authors in Author Co-citation Analysis

    The present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

    Variations on the Author

    “Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship

    Wheat husk: A renewable resource for bio-based building materials

    The huge annual production of wheat husk in Europe (10 million tons) creates management problems. Valorization options are thus sought. Here, insulting lime concrete was designed using native wheat husk as lightweight aggregate. Physical-chemical and technological properties of both particles and concretes were determined. Comparisons with hemp concrete manufactured with the same process were made. Similar thermal conductivities for the two types of concretes were obtained (ca. 0.09 W/(m·K)), whereas slightly lower compressive strength was found for wheat husk concrete due to weaker particle-binder interface. Nevertheless, results highlight the high potential of raw wheat husk for development of bio-based materials with interesting performances
