The article deals with the typology of Baroque frontispieces in printed books published in Bohemian and Moravian printing houses in 1618–1765, which is viewed in terms of the function of the frontispieces in printing. The paper contains a detailed analysis of the main thematic variants of frontispieces. The thematic variants are analysed with respect to the content and genre of the work concerned with the aim to determine the main marketing strategies of Bohemian and Moravian printers, publishers or booksellers in the visual promotion of their products.
The aim of the study is to provide basic summary of the factors that influence the involvement of grandparents in the care for young children in the Czech families and to introduce a typology of the patterns of grandparent role. The paper presents results of both quantitative and qualitative analysis. The first part of the paper uses the data from the second wave of SHARE 1) to outline the typology of grandparents’ involvement with respect to different forms and intensity of contacts with grandchildren and the geographical proximity of family members and 2) to map how the socio-demographic factors influence the forms and intensity of involvement in the care for grandchildren. The second part of the paper focuses on the subjective experience of Czech mothers and grandmothers. 18 mothers and 12 grandmothers of children younger than 10 years were interviewed. The paper points out the existence of various conceptions of grandmothers’ role in the Czech families., Jaroslava Hasmanová Marhánková, Martina Štípková., and Obsahuje seznam literatury
Článek se věnuje popisu základních skupin kořenových útvarů registrovaných v jeskyních České republiky. Zároveň se krátce zmiňuje o nově objevených lokalitách v letech 2006 a 2007. K nejpozoruhodnějším nálezům se řadí objev kořenových stalagmitů v krasové jeskyni z centrální části Moravského krasu. and Main groups of root formations registered in the caves of the Czech Republic are described. The article also mentions sites newly discovered in 2006 and 2007. Root stalagmites of the karst caves in the central part of the Moravian Karst are among the most interesting discoveries.
This article refers to the rich vegetation on the rocky slopes along the Achensee (Tyrol, Northern calcareous Alps, Karwendelalpen) described by Professor Anton Kerner 150 years ago. The vegetation today is much less diverse, the subalpine species abundant in the last centuries are absent while the species of mixed mountainous forest prevail. The abundance of the Heather (Calluna vulgaris), which was not mentioned by A. Kerner, may indicate acidification due to acid rain. And the retreat of subalpine species may indicate the on going change to a warmer climate. and Jarmila Kubíková.
Incubation of maize NADP-malic enzyme with tetranitromethane (TNM) resulted in a total loss of enzyme activity. The loss of enzyme activity was not observed at pH 6.3 but at pH 8.0. NADP-malic enzyme was inactivated to almost 90 % by incubation with an 80-fold molar excess of TNM for 5 min at 30 °C. The substrate malate or Mg2+ alone gave no protection, while NADP provided considerable protection. NADP in the presence of malate and Mg2+ totally protected the enzyme activity, suggesting that tyrosine residue may be located at or near the active site of maize NADP-malic enzyme. The spectral analysis of the modified enzyme indicated that modification of at least one tyrosine residue per subunit resulted in complete loss of the enzyme activity. The fluorescence study of unmodified and modified enzymes postulated that essential tyrosine residue at maize NADP-malic enzyme is possibly involved in malate binding. and S. R. Rao, B. G. Kamath, A.
