On the existence of a negative pasteur effect in yeasts classified in the genus Brettanomyces Kufferath et van Laer
Get PDFEven at a mere glance at the extensive literature on the influence of elementary molecular oxygen on the alcoholic fermentation in living yeast cells and various yeast preparations it is evident that so far most works have been concerned with the inhibiting effect produced by this gas on the rate and extent of the process mentioned. Particularly the relation between the anoxybiontic fermentation and the respiration as measured by the oxygen consumptionwas and still is one of the main subjects of investigation and speculation. This state of things is confirmed strikingly on studying recent volmnes on cellular biochemistry like the "Proceedings of the International Symposium on Enzyme Chemistry, Tokyo and Kyoto 1957", and the "Ciba Foundation Symposium on the Regulation of Cell Metabolism", which appeared in 1958 and 1959, respectively.Applied Science
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Method for producing ethanol from xylose-containing substance
No full textA method for producing ethanol from a D-xylose containing substance, comprising fermenting said substance with a yeast of the genus Pichia or its imperfect forms belonging to the genus Candida, selected from the species consisting of Pichia stipitis, Pichia segobiensis and Candida shehatae, under aerobic or anaerobic conditions to produce ethanol in a yield, in the absence of constituents severely inhibitory to the process, of at least 0.43 g. ethanol, per g. of D-xyloseApplied Science
Variations on the Author
Get PDF“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
