V dobách, kdy v obecném povědomí byl termín dislokace znám jen ve spojení "dislokované zlomeniny kostí" či "dislokace pracovníků nebo celých institucí do vybraných prostor", začal Frntišek Kroupa propagovat ve fyzice a materiálovýcha vědách dislokace, čárové poruchy krystalické struktury. Dislokace, původem z matematiky jako označení singularit kontinua, byly zavedeny ve fyzice krystalů ve třicátých letech minulého století a experimentálně byly prokázány až o dvacet let později., Václav Paidar., and Obsahuje bibliografii
The number of copies of Wyclif's Latin works that derive from Bohemia and are mostly preserved now in Prague and Vienna is familiar ground. The evidence for the scrutiny of those works is less frequently mentioned: very extensive indexes were provided in Bohemia for many of the longer works, together with a catalogue of 115 items by Wyclif, listing titles, incipits and explicits and the number of books and chapters for each. Even more remarkable are the copies of the writings of some of Wyclif's English followers, though some of these followers were in correspondence with Bohemian fellows, some of the texts narrate entirely English affairs that would seem of little interest so far away. The paper surveys these manuscripts and notes the questions that they raise. and Anne Hudson.
The study offers a basic overview of the manuscripts of the ars memorativa treatises in late medieval Czech lands. On the basis of the surviving evidence it is possible to prove that during the 15th century this ancient art (however suspicious and cumbersome it may seem today) was known and practiced here. It coexisted with general (often primarily medical) set of advices on efficient studying some of which openly criticize the art of memory for being too impractical. Besides copies of Italian and West European art of memory models, there is a number of these treatises and shorter treatments of the art composed in the Czech lands. Each of them includes specific features and innovations not encountered elsewhere. The manuscript context of ars memorativa shows that it was not seen as a part of rhetoric theory intended for a restricted number of intellectuals but as a means of storing and recuperating important information actively used especially by students and preachers. and Lucie Doležalová.
