Computational and experimental assessment of natural frequencies in a bladed disk system
Mekhalfia, Mohammed Lamine ; Procházka, Pavel ; Maturkanič, Dušan ; Voronova, Evgeniya ; Hodboď, Robert
This paper examines the modal characteristics of a bladed disk in rotating machinery systems using a combination of analytical and experimental modal analysis methods. The analysis involves measuring natural frequencies and mode shapes under different operational conditions. A comparative analysis is conducted to assess modal properties obtained from both analytical and experimental approaches, while also considering the influence of rotation speed. Additionally, Finite Element Method (FEM) outputs are used to accurately position the strain gauge. Integrating these techniques provides a comprehensive understanding of the bladed disk's behaviour under varying rotational speeds, enhancing result accuracy and facilitating thorough investigation within rotating machinery systems.

Media discourse on Green Deal from energy perspective
Kolářová, Marta
Green Deal, the European Commission's initiative to protect the climate and reduce emissions greenhouse gases, has sparked controversy in the Czech public debate. An analysis of media discourse on the Green Deal from an energy perspective shows that the Green Deal is perceived predominantly negatively. In the media, it has been labelled with condemnatory statements and negative characteristics, especially by leading Czech politicians. A more favourable view of it is held by Czech companies, municipalities and experts. The public debate is being transformed in particular by the impact of the war in Ukraine in favour of energy security and accelerating the green transformation.

4th CCP Phenogenomics Conference abstract book
Sedláček, Radislav
The fourth CCP Phenogenomics Conference was held as a hybrid meeting. The scientific committee selected the topic of rare diseases: experimental models & delivery of therapies as the main thematic focus of the 2022 Conference. The Conference provided again an excellent opportunity to support networking and interactions among the researchers, CCP staff, users and experts from the commercial sector.
