	Explicit dynamic finite element analysis of a firing pin assembly Mochar, Dominik ; Gabriel, Dušan ; Masák, Jan ; Kopačka, Ján ; Kolman, Radek ; Plešek, Jiří ; Hynek, P. ; Vtípil, J. In this paper, explicit dynamic finite element analysis of a firing pin assembly was performed. Two different geometries of the firing pin were considered using the finite element software PMD and Abaqus. For both variants there was evaluated a stress distribution at the critical point of a tested component, that is going to be later used for a fatigue analysis of the firing pin. Detailed record
	Implication of ligninolytic enzymes produced by immobilized white-rot fungi in decolorization of synthetic dyes Šušla, Martin ; Novotný, Čeněk (advisor) ; Gaper, Jan (referee) ; Masák, Jan (referee) 6 Abstract The aim of this Ph.D. thesis was to characterize ligninolytic activities of two white- rot fungi, Dichomitus squalens and Irpex lacteus, cultivated on various solid supports in their immobilized form and to identify the role of ligninolytic enzymes in the decolorization of synthetic dyes. Significant induction of laccase activity was observed in D. squalens pine wood cultures when compared to liquid cultures. The induction of laccase was probably due to the presence of phenols, extractable from wood with organic solvents. Two laccase isoforms, Lc1 and Lc2, were isolated from the culture liquid using FPLC. The enzymes revealed identical molecular masses of 68 kDa, however, they differed in isoelectric points and their dye decolorization capacity. The decolorization of the azo dye RO16 by Lc1 in the presence of redox mediator was followed by a regressive colorization of the sample when incubated for 72 h. Conversely, no backward trend was observed during RO16 decolorization using Lc2. In contrast to D. squalens, I. lacteus immobilized on pine wood cubes produced a low level of manganese peroxidases and no laccase induction was observed. Both fungi produced MnP as a dominant enzyme in solid state wheat straw cultures. D. squalens MnP obtained from the wheat straw cultures was able to decolorize... Detailed record
	Explicit dynamic FE analysis of a firing pin assembly Mochar, Dominik ; Masák, Jan ; Gabriel, Dušan ; Kolman, Radek ; Kopačka, Ján ; Plešek, Jiří In the report the results of explicit dynamic finite element analysis of a firing pin assembly are summarized.

	Evaluation of general methodics for assessment of admissibility of found in-operation indications in heterogeneous welds in NPP equipment\n Pták, Svatopluk ; Masák, Jan ; Gabriel, Dušan In this report, we evaluate a general methodics for the assessment of the admissibility of in-operation found indications in heterogeneous welds in NPP equipment. The methodics is prepared in cooperation with the Czech Association of Mechanical Engineers (A.S.I.). The name of the prepared methodics is "Zvláštní případy zařízení a potrubí jaderných elektráren typu VVER - Případ 7/2016".\n Detailed record
	Evaluation of documentation on assessment of four selected cases assessing found indications in welds on NPP equipment Pták, Svatopluk ; Masák, Jan ; Gabriel, Dušan The report is focused on an evaluation of a documentation on the assessment of four selected cases assessing found indicators in welds on Czech NPP equipment. The chosen approach to the assessment of the specific finding is thoroughly evaluated for each of the four selected cases. Detailed record
	Creep Analysis of the High Pressure Inner Vessel DSPWR - comparison of creep models Masák, Jan ; Gabriel, Dušan ; Hrubý, Zbyněk ; Plešek, Jiří The report summarizes the results of II. stage creep analysis of the High Pressure Inner Vessel DSPWR. In the first part of the report two standard creep models are briefly introduced describing the secondary stage creep (Norton's law) and primary stage creep (Norton-Bailey's law), including the verification of results. In the second part of the report the results of all calculations on the High Pressure Inner Vessel are presented using considered creep models. Detailed record
	Case study using the creep probabilistic exponential model and explicit integration method with time step control Gabriel, Dušan ; Hrubý, Zbyněk ; Masák, Jan ; Plešek, Jiří ; Kopačka, Ján ; Pařík, Petr ; Straka, F. ; Albl, P. The issues concerning accuracy and stability control of original explicit algorithm for integration of differential systems arising from viscoplastic or creep finite element analyses was explored. The attention was focused on the investigation of the numerical stability for complex creep probabilistic exponential model with damage. Detailed record
