APPLICABILITY VERIFICATION OF AUTOFORM SOFTWARE FOR FEM SIMULATION OF MECHANICAL FIXATION OF HEMMED JOINTS

This paper deals with the problematics of fixation of hemmed joints, especially with one specific mechanical method how to ensure a dimensional stability of a hemmed joint of car-body parts, such as doors, bonnet and trunk lid, during the production process in the automotive industry. It also evaluates simulations and verify the possibility of the use of the Autoform software for this problematics. In the paper, the possibility of using the law of similarity in the analysis of the compressibility of small parts by Autoform is described

Czeskie lokalne struktury opozycyjne w 1989 r. w perspektywie oral history

Studies Czech Opposition Structures at the Local Level in 1989 through the Eyes of Oral History is devoted to the description and analysis of anti-regime activities of czech society at the level of towns and regions. The main source of knowledge are mainly interviews with the participants, led by the method of oral history. The aim of the study is primarily to show the variety of activities that took place at the local level, despite the repressive power of the communist regime in Czechoslovakia

Execution, elections and civic participation in the Czech Republic

Studie se zabývá důležitou, ale doposud málo zmapovanou problematikou vztahu mezi fenoménem exekucí a jejich dopadu na ochotu se občansky angažovat, včetně volebního procesu. Autor dospívá k závěru, jednoznačně podpořeného empirickým výzkumem agentury Median, že exekuce mají nejen ekonomický a sociální dopad, ale výrazně, a to negativně ovlivňují i politické chování občanů. Lidé v exekučním řízení vykazují výrazně menší ochotu chodit k volbám, nevěří stávajícímu politickému systému a jsou občansky pasivní - nevěří, že by jakákoliv veřejná aktivita mohla vést ke zlepšení jejich sociální situace.The study deals with an important but not yet mapped issue of the relationship between the distraint phenomenon of execution and its impact on the willingness to engage in civic engagement, including the electoral process. The author concludes, unequivocally supported by empirical research by Median Agency, that executions not only have an economic and social impact, but have a significant impact on the political behavior of citizens. People in execution proceedings show significantly less willingness to vote, do not trust the current political system and are civic passive - they do not believe that any public activity could improve their social situation

Selective self-assembly and light emission tuning of layered hybrid perovskites on patterned graphene

The emission of light in two-dimensional (2-D) layered hybrid organic lead halide perovskites, namely (R-NH3)2PbX4, can be effectively tuned using specific building blocks for the perovskite formation. Herein this behaviour is combined with a non-covalent graphene functionalization allowing excellent selectivity and spatial resolution of the perovskite film growth, promoting the formation of hybrid 2-D perovskite : graphene heterostructures with uniform coverage of up to centimeter scale graphene sheets and arbitrary shapes down to 5 μm. Using cryo-Raman microspectroscopy, highly resolved spectra of the perovskite phases were obtained and the Raman mapping served as a convenient spatially resolved technique for monitoring the distribution of the perovskite and graphene constituents on the substrate. In addition, the stability of the perovskite phase with respect to the thermal variation was inspected in situ by X-ray diffraction. Finally, time-resolved photoluminescence characterization demonstrated that the optical properties of the perovskite films grown on graphene are not hampered. Our study thus opens the door to smart fabrication routes for (opto)-electronic devices based on 2-D perovskites in contact with graphene with complex architectures
