The article presents two likely and so far unknown compilers of the third edition of Koniáš’s Key from 1770. Their names have been revealed by a handwritten note in a copy that was originally a part of the library of the private collector Josef Bartsch (1731-1803). Concerning the first figure, the Jesuit Josef Kögler, the treatise describes his career in the Jesuit Order and the posts that he held. In the case of his co-worker Jan Kohout, the text outlines the possible connections that might help identify him precisely. and David Mach.
Poezie světla, mystičnost i melanchonie - slova, tkerá si patrně všichni spojujeme s jedním z nejvyznamějších českých fotografů, Josefem Sudkem (1896-1976). Jeho práce se světlem, absolultní smysl pro kompozici a talent zobrazit obyčejný předmět neobyčejně, putavě až magicky dodává fotografiiím nenapodobitelný náboj. Je obdivuhodné, že to platí i pro jím vyhotovené komerční zakázky. and Gabriela Adámková, Josef Sudek.
The nature and rate of juvenile hormone (JH) biosynthesis and effects of allatostatins and allatotropin have been investigated in isolated corpora allata (CA) of adults and larvae of the noctuid tomato moth, Lacanobia oleracea. In adult female CA, mean rates of synthesis were relatively constant (10-16 pmol/pr/h) at all times. However, the range of JH synthesis by individual CA of similarly aged insects was quite large (2-30 pmol/pr/h). High performance liquid chromatography (HPLC) separation shows that adult female moth CA synthesise predominantly JH I and JH II. Rates of JH synthesis in vitro are dependent on methionine concentration. Synthetic Manduca sexta allatostatin (Mas-AS) caused a dose-dependent inhibition of JH synthesis by adult female CA but only to a max. of 54%, whilst 10 µM synthetic M. sexta allatotropin caused a 37% stimulation of CA activity. At 1 mM the cockroach allatostatin, Dip-allatostatin-2, had no significant effect on JH synthesis. In larval L. oleracea, rates of JH biosynthesis were very low., Neil Audsley, Robert J.
