Plant virology department of the Institute of Plant Molecular Biology, Biology Centre of the Czech Academy of Sciences, is successful in description and sequencing of mycoviruses and plant viruses, recently. Most of the newly described viruses have unique genome organization and did not induce disease symptoms in their plant of fungal hosts, respectively. By contrast, some mycoviruses debilitate their hosts and are promising as tools for biological control of harmful fungi. and Karel Petrzik, Ondřej Lenz.
The article provides a language analysis of the idea of progress. It briefly outlines the method of search for mimimal vocabulary as has been proposed by Bertrand Russell in Human Knowledge, Its Scope and Limits. Then it coniders the application of this method to a social theory, namely to the language used in a theory of progress. As and expample theory it uses the well known essay L´anciene regime et la revolution (1856) by Alexis de Tocqueville. The language of the theory is analyzed, abstracted expressions are pointed out and the minimal vocabulary is presented: it consists of verb-expressions "to see", "to be wrong", "to dobut", "to think", "to feel", "to be surprised", " to choose", "to express" and To rely"; of noun-expressions "demise", "cause", "change", "nature" and "banality" together with pronouns and logical expressions. The rules for construction of composed expressions and propositions are set up and a reconstruction of the object language is suggested. The abstract character of the method is reflected., Tomáš Holeček., and Obsahuje seznam literatury

Vyplývá z bezvadně provedeného důkazu také závazek počítat ve svém dalším rozvažování a jednání s jeho závěrem? V předložené studii se zabývám Hobbesovým Leviathanem coby "literární technologií", která čtenáře staví do role autora v Leviathanu rozvíjené argumentace. V tomto smyslu kriticky navazuji jednak na interpretaci Hobbesova vědeckého stylu, kterou nabízejí S. Shapin a S. Schaffer, jednak na výklad Q. Skinnera, který se podrobně zabývá Hobbesovou rétorickou praxí. Nabízím tezi, podle níž se Hobbes v kontaktu se svým publikem nespokojuje s předvedením vědeckého důkazu, nýbrž své čtenáře nechává na vytváření vědecké argumentace a jejím závěru osobně participovat., Does a perfectly established proof also imply, for its beholder, a commitment to account for the proof’s conclusion in further reasoning and action? In the herein presented study, I treat Thomas Hobbes’s Leviathan as a “literary technology” that seeks to position the reader into the role of the author of Leviathan’s argumentation. The interpretations of Hobbes’s scientific style offered by S. Shapin and S. Schaffer are thus critically developed alongside Q. Skinner’s analysis of Hobbes’s rhetorical practice. It is suggested that, with regard to his readers, Hobbes does not content himself with merely demonstrating a scientific proof, but strives to involve his readers in his argumentation and make them participate in the creation of scientific arguments and their conclusions., Jan Maršálek., and Obsahuje bibliografii
