Several Notes on the Epitaph of Count Sendebald in Gorze Abbey.
Vrána, David
Count Sendebald first appears in the office of Count of Toul under the episcopate of Bishop Gauzlin sometime before 962, then becomes count palatine of the bishops of Metz after 981, and dies on 21 March after 987. He bequeathed the Martincourt estate north of Toul to the monastery of Gorze probably not long before his death. Perhaps it was this circumstance, together with his intervention against the unjust handling of the Amel estate, that led him to find his final resting place in Gorze. The tomb is assumed to have been marked by an epitaph, the text of which was preserved in a manuscript that belonged to the Saint-Vincent Abbey in Metz at the time of Sendebald’s death (Berlin State Library, Ms. Phill. 1877). Comparison with other epigraphic and sepulchral monuments that can be associated with the Gorze Monastery in the second half of the 10th century is problematic. We know that Count Giselbert († c. 964) was buried here, but we have no further details. An epitaph may have adorned the tomb of Giselbert’s brother, Bishop Adalbero († 964), the creation of which is linked to the transfer of his body from Saint-Trond Abbey to Gorze. We are also familiar with the incomplete text of the epitaph only from a manuscript. A possibility for comparison may be found in the description of the epigraphic monuments in Saint-Vincent Abbey in Metz, which the Vita Deoderici informs us about. Sendebald’s epitaph contains a number of allusions to unknown historical facts, especially concerning his noble origin. A comparison of the memorial records indicates the possibility that he was an ancestor of Hemma of Gurk and was related to the nobility of Bavaria, Lotharingia, and Saxony, and it cannot be excluded that he may have been a descendent of the Moravian Moymirids.

Virtuální procházky historickými krovy: Nové nástroje pro zpřístupnění skrytých součástí kulturního dědictví
Bláha, Jiří ; Buzek, Jaroslav ; Novotný, Jakub
Historické krovy z důvodu své konstrukční podstaty a umístění představují pro běžného návštěvníka často obtížně nebo zcela nepřístupnou část stavby. Cílem příspěvku je zhodnotit potenciál informačních a komunikačních technologií (ICT) pro zpřístupňování a popularizaci této významné vrstvy hmotného architektonického dědictví. Nejprve je podán přehled\ntradičních metod dokumentace a zobrazování krovových konstrukcí a uvedeny jejich výhody a omezení. Následně jsou představeny moderní ICT nástroje (LiDAR, fotogrammetrie, 3D skenování a modelování, digitální mapy, rozšířená realita) a jejich aplikace na případových studiích konkrétních historických krovů (Cheb a Jihlava). Práce využívá metodiku případových studií. Díky stále dokonalejším a dostupnějším nástrojům pro převedení fyzicky dochovaných konstrukcí do virtuálního prostředí mohou odborníci efektivněji třídit získaná terénní data a specifikovat užitnou, historickou či památkovou hodnotu příslušného krovu. Virtuální prohlídky a interaktivní modely využívající ICT zpřístupňují tyto památky všem zájemcům, a to bez ohledu na jejich fyzické možnosti či omezení. Zároveň přispívají k rozšíření turistické\nnabídky a posilují povědomí o hodnotách hmotného i nehmotného (dobové řemeslně-technologické postupy) kulturního dědictví.

How Sir Harold Jeffreys would create a belief function based on data
Daniel, Milan ; Jiroušek, Radim ; Kratochvíl, Václav
Not all normalized nonnegative monotone set functions are belief functions. This paper investigates ways to modify them to obtain a belief function that preserves some of their properties. The problem is motivated by an approach to data-based learning of belief function models. The approach is based on the idea that classical methods of mathematical statistics can provide estimates of lower bounds for unknown probabilities. Thus, methods of mathematical statistics can be used to obtain a reasonable rough estimate, which is further elaborated to obtain a desired belief function model.

Fluorinated Methyl Β-lactosides and Their Multivalent Presentation
Krčil, Aleš
This work is focused on a full series of mono-deoxyfluorinated methyl β-lactosides, synthesized via glycosylation of methyl glucoside with appropriately protected galactose donors, followed by deprotection. These derivatives are designed for affinity testing with selected human galectins using ELISA. Additionally, a strategy for multivalent ligand presentation is introduced: corresponding β-lactosyl azides were prepared for conjugation onto dendritic scaffolds via click chemistry. These multivalent constructs are useful for studying cluster effects and enhancing binding in lectin–glycan interactions.

Optimization of Continuous Synthesis of Trazodone
Jaklová, Natalie
This study explores the feasibility of synthesizing Trazodone in continuous mode using a tubular reactor and investigates the impact of ultrasound\non phase-transfer catalyzed (PTC) N-alkylation. One of the suitable approaches for a continuous system was solid-liquid arrangement described\nby Jaśkowska et. al, while synthesis is carried out in two steps with ultrasound assistance. The hypothesis for the reaction intensification with solid-liquid arrangement is that sonication accelerates transport at the solid-liquid interface and thus intensifies the reaction.
