Dependence of ATP hydrolysis kinetics by the chloroplast coupling factor (CF1) on medium viscosity was studied at varying temperatures. For samples with oxidized and reduced CF1 γ-subunit, this dependence was shown to be described by Cramers’ relationship k - (η/ηo)-n, where k is the reaction rate constant, η/ηo is the medium/water viscosity ratio, and 0 < n < 1. Transition of the γ-subunit from its reduced to oxidized state was accompanied by increasing n value, which is indicative of increasing friction losses between certain enzyme sections and the solution. The increased medium viscosity produced no effect on the reaction activation energy which appeared to be almost the same for the both enzyme states. The molecular mechanisms responsible for CF1 activity loss in viscous media are discussed., A.N. Malyan., and Obsahuje bibliografii
The missal of Načeradec is a modest codex from an artistic point of view. Its decoration is limited to one figural illumination only – a canon depiction of the Crucifixion; besides this, the manuscript contains only filigree initials and clerical capitals. The quality of its figural decoration is comparatively high. Its style is post-classical Gothic; linear pleats of the draperies imply a date in the beginning of the 14th century. Only a few analogies can be found in simultaneous book painting, e.g. in the decoration of the manuscripts of Eliška (Elisabeth) Rejčka, but these analogies are not immediate. Some correspondence, however, can be found in monumental art, more precisely in mural painting.
The Zittau library of Christian Weise has an extensive collection of manuscripts, among which we find a number of early modern-era chronicles relating particularly to the six towns of the Lusatian League. One of these is the Zittau Chronicle by Tobiáš Schnürer from the 16th century, preserved in a later transcription, in which he chronologically recorded the most important events of his era, including the names of members of the Town Council. Memorial and chronicle records are also included in a collection of manuscripts by Abraham Frenzel (1656-1740). This includes a preserved transcription of an early modern-era chronicle of Sorau (Żary), which details the problems of life in the town and the local authority at the time. Another of Frenzel's preserved manuscripts describes the journey through Europe made by Michael Frank at the end of the sixteenth century, including his visit to Bohemia.
