In contrary to general interpretations of opera buffa, the presence and importance of arias and ensembles based primarily on emotions (and not only action) are crucial for the genre’s dramaturgy as well as for its historical development. The presence of lyrical arias in opera buffa has its origins in the traditional comic dramaturgy (one or more couples of serious lovers), the number, form and functions of such arias, however, changed considerably during the 18th century. Not only the use of Tuscan Italian, but also adopting new music features of opera seria for lyrical arias of noble lovers (in 30ties) led to the rapid dissemination of the genre. Similarly, broadening of the typology of characters and its emotions in the works of Goldoni and his composers, mostly the including of the sentimental plots and its new kind of heroine, supported the popularity of opera buffa and its transformation to the leading operatic genre in the second half of 18th century., Marc Niubo., and Obsahuje bibliografické odkazy
Diurnal and seasonal fluctuation in ambient CO2 concentration (C^) of more than 100 cm^ m‘3 in urban areas is an important abiotic factor influencing photosynthetic activity. This was shown in a young poplar tree under controlled environmental conditions. Here, the short-term rise in from 320 to 360 cm^ m‘3 during a day resulted in a 10 % higher CO2 gain. This variation in also influenced the interpretation of CO2 exchange data. Calculation of the intemal CO2 concentration in a leaf, Q, on the basis of an assumed mean value of atmospheric CO2 of 340 cm^ m'^ led to a possible 8 % divergence ffom the actual Cj in our experiments and thus also to a falše interpretation of the results, as it concealed the photosynthetic response to a rise or decline of Cg. Additionally, the changing CO2 concentration directly influenced the measurement by the infrared gas analyzer, because of its nonlinear response. Lack of compensation for this can lead to an additional inaccuracy of 3 to 8 % in the calculation of net photosynthetic rate and Q.
Comparison of one of the commentaries on the Apocalypse which originated at the Prague University and is contained in the manuscript Osek Cist. 37 of the Prague National Library, ff . 1–129, coming from Osek, dating from 1402 and used to this day by experts, with a copy of the same work in the manuscript I Q 16 of the University Library in Wroclaw, created 1378, has excluded the hitherto assumed authorship of Heřman Švab of Mindelheim, as well as the authorship of Heřman of Prague, assumed, not beyond doubt, by Fr. Stegmüller. Temporal relationship and the data of the colophones of both of these preserved manuscripts lead to the conclusion that the author of this Commentary is an other „Doctor Heřman“, Heřman of Winterswick, a member of the Prague university who composed the Commentary sometime in the late seventies of the 14th century.
Eight species of fishes from rivers of Northern Portugal were examined for cestodes but only one, Barbus barbus bocagei (Steindachner), was infected: river Este (4 of 12 infected, 1,1,4 adult and 37 juvenile cestodes found respectively), Lima (1 of 8 infected, 1 juvenile cestode), Paiva (1 of 5 infected, 57 juvenile cestodes) and Sousa (1 of 13 infected, 1 adult cestode). The cestodes were Caryophyllidea. The fan-shaped scolex had very shallow incisions, with the scolex separated from the hindbody by a neck. The first vitelline follicles started a considerable distance anterior to the testes, with some vitelline follicles along the lateral margins of the cirrus sac, uterine coils and H-shaped ovary. The uterine coils extended forward to the posterior half of the cirrus sac. Transverse transmission electron microscope sections showed cortical vitelline follicles and medullary testes validating Lytocestidae. These features identify Khawia baltica Szidat, 1941, described from tench Tinca tinca (L.) in East Prussia and subsequently reported from barbel B. barbus and T. tinea in Russia, This is a new host and first record from Portugal and western Europe, thus extending the known range of distribution of K. baltica.
During his approximately fifteen-year-long appealing to the members of Czechoslovak ethnographic community, Otakar Nahodil attempted to open a “research window” at least within the dimensions of the then Socialist camp with the emphasis on the practice of Soviet ethnographers. In accordance with his opinion, which was based on the idea of regional closed nature of research conducted by Czechoslovak ethnographers, he tried to break this closed nature by advancing Soviet ethnographic science. His life story has not been forgotten by the older generation, but less attention is paid to Nahodil´s views of theory and methodology of ethnographic work. We can observe his professional endeavour in several projects through which he tried to change opinions of the local ethnographic community. These were his view of the concepts of Marxist ethnography in theory and practice, his methods he applied on his own fieldwork (in Bohemia, Slovakia, Caucasus,
Central Asia and Egypt), the themes which the Czechoslovak Marxist ethnography was to paid attention to, and the project of the journal “Československá etnografie (Czechoslovak Ethnography)”. In principle, the text is a sequel to the article by Lydia Petráňová, which is devoted to Otakar Nahodil´s life story (Národopisný
věstník 2017/1).
