Deformation behaviour of gellan gum based artificial bone structures under simulated physiological conditions
Krčmářová, N.; Šleichrt, J.; Fíla, Tomáš; Koudelka_ml., Petr; Kytýř, Daniel
2017 - English
The paper deals with investigation of deformation behaviour of gellan gum (GG) based\nstructures prepared for regenerative medicine purposes. Investigated material was synthesized as porous spongy-like scaffold reinforced by bioactive glass (BAG) nano-particles in different concentrations. Deformation behavior was obtained employing custom designed experimental setup. This device equipped with bioreactor chamber allows to test the delivered samples under simulated physiological conditions with controlled flow and temperature. Cylindrical samples were subjected to uniaxial quasi-static loading in tension and compression. Material properties of plain scaffold buffered by 50 wt% and 70 wt% BAG were derived from a set of tensile and compression tests. The results are represented in form of stress-strain curves calculated from the acquired force and displacement data. Keywords: gellan gum scaffold; reinforcement; uni-axial loading; simulated physiological conditions Available at various institutes of the ASCR

Nanopatterning of Silicon Nitride Membranes
Matějka, Milan; Krátký, Stanislav; Řiháček, Tomáš; Kolařík, Vladimír; Chlumská, Jana; Urbánek, Michal
2017 - English
Membranes are typically created by a thin silicon nitride (SIN) layer deposited on a silicon wafer. Both, top and bottom side of the wafer is covered by a thin layer of the silicon nitride. The principle of silicon nitride membranes preparation is based on the wet anisotropic etching of the bottom side of the silicon wafer with crystallographic orientation (100). While the basic procedure for the preparation of such membranes is well known, the nano patterning of thin membranes presents quite important challenges. This is partially due to the mechanical stress which is typically presented within such membranes. The resolution requirements of the\nmembrane patterning have gradually increased. Advanced lithographic techniques and etching procedures had to be developed. This paper summarizes theoretical aspects, technological issues and achieved results. The application potential of silicon nitride membranes as a base for multifunctional micro system (MMS) is also\ndiscussed.

Olanzapin patří do skupiny atypických antipsychotik a běžně se používá při terapii schizofrenie. Zaměřili jsme se na změny perfuze mozkové tkáně u zdravých a MAM upravených zvířat. Detekovali jsme významně nižší prokrvení mozkové kůry při akutních a chronických olanzapinem léčených zvířat. Olanzapine belongs to the first choice drug in treatment of schizophrenia. We focused on blood perfusion changes inducted by acute and chronic application of olanzapine in healthy animals and MAM altered animals. We detectet significant lower perfusion of cerebral cortex in acute and chronic olanzapine treated animals. We susspect that it could be due to altered neurotransmiter regulation caused by olanzapine. Keywords: olanzapine; ASL; MAM Available at various institutes of the ASCR

Válkou k objevům. Denonova cesta za uměním
Hrbata, Zdeněk
2017 - Czech
Analýza knihy Voyage dans la Basse et la Haute Égypte Vivanta Denona, člena Napoleonovy vojenské expedice do Egypta, a jejích různých diskurzivních rovin, které tvoří a) kronika vojenské kampaně a zároveň deníkový cestopis, b) objevování a dokumentarizace egyptských památek, c) ohlasy preromantických estetik (estetika vznešena a přírody, poetika ruin). This paper analyses the key discourse levels in Voyage dans la Basse et la Haute Égypte, a book by Vivant Denon, a member of the society of scholars and artists that accompanied Napoleon’s military expedition to Egypt. From May 1798 to October 1799 Denon wrote a chronologically incomplete chronicle of the Egyptian campaign, including battles, encounters, pursuits, the horrors of war and the extreme conditions, a chronicle that is concurrently a travelogue journal with the customary topics (inhabitants, mores and customs) and an epic structure (the voyage, obstacles, wanderings and struggles). Moreover, as the author looks around ebes, Luxor, Denderah (Tyntiris) and Aswan, he colourfully and enthusiastically relates the discovery of Egypt, carefully describing and tirelessly drawing. The variety of discourses in Denon’s Travels (e.g. the discourse of war and its heroization, as well as its cruel aspect; the discourse of discoveries and emerging Egyptology; travelogue discourse) gradually takes on the form of the rivalry and conflict of different times. Keywords: war; discovery; art Available at various institutes of the ASCR

Po katastrofě – kolportážní román jako řemeslo a výraz vnitřního dialogu. Morana čili Svět a jeho nicoty
Janoušek, Pavel
2017 - Czech
Autor analyzuje prózu Morana čili Svět a jeho nicoty (Morana nebo svět a jeho nicota), kterou Karel Sabina publikoval v roce 1874 pod pseudonymem Arian Zelinský jako výraz své osobní, filozofické a především literární reakce na "národní soud ", což souvisí s jeho odhalením jako policejního agenta, následnou exkomunikací a označením za zrádce národa. The author analyses the prose work Morana čili Svět a jeho nicoty (Morana or The World and its Nothingness) which Karel Sabina published in 1874 under the pseudonym Arian Želinský, as an expression of his personal, philosophical and above all literary reaction to the “national court”, which unmasked him as a police agent and turned him into an excommunicated “traitor to the nation”. The objective here is to establish the manner in which Sabina reflected his private fall from grace in his literary testimony, working inter alia with the flood motif, which was inspired by the disastrous floods of May 1872, i.e. the way he reflected his internal discord in the external form of a conventional serialized pulp novel with an aristocratic setting, with mordant dialogue between various life truths. Keywords: Czech literature; 19th century; serialized pulp novel; Sabina, Karel; postmodern prose; national court; 1872 flood; literary irony Available at various institutes of the ASCR

Overlapping domain decomposition preconditioners for elliptic and parabolic problems in primal and mixed form
Blaheta, Radim
2017 - English
In this lecture, we concern the numerical solution of PDE problems and describe overlapping domain decomposition, which provides a tool for the construction of parallelizable Schwarz type iterative solvers and preconditioners. The idea of using overlapping domain decomposition goes back to Schwarz alternating method from 1870, see [1]. The analysis of this alternating iterative method was evolved by great mathematicians, see e.g. S.L. Sobolev (1936), R. Courant and D. Hilbert (1937), S.G. Michlin (1951), M. Práger (1958), I. Babuška (1958), F.E. Browder (1958). The use of overlapping domain decomposition for parallel computations started in the late eighties in the work of M. Dryja and O. Widlund [4], P.L. Lions [5, 6], S. Nepomnyaschikh [7] and others and continue up to the present days. The origin of the alternating Schwarz method is nicely described in [8]. Keywords: preconditioners; Schwarz method; matrix Ma Fulltext is available at external website.

Parameter Optimization of Multi-Level Diffraction Gratings
Matějka, Milan; Kolařík, Vladimír; Horáček, Miroslav; Král, Stanislav
2017 - English
Originally, the e-beam lithography (EBL) is a technique for creating high-resolution black and white masks for the optical lithography. Multi-level relief structures can be also prepared using EBL patterning. Their preparation is based on the image patterning with a gradient of exposure doses. Large-area multi-level structures can be effectively prepared using the electron beam pattern generator with a variable shaped beam. We present several writing strategies. Basically, the main writing strategy uses one stamp (i.e. one elementary exposure of the shaped electron beam) per one elementary area with the same exposure dose. This simple approach is fast and flexible, however it does not guarantee optimal results. The main problem is an imperfection of the stamps (size, shape, and homogeneity). Advanced algorithms are based on multiple\nexposure of the same elementary area, the total local exposure dose is a sum of several different elementary exposures (stamps). Using these algorithms, a smoother surface of the structure can be achieved. On the other hand, the writing speed is considerably decreased. Tradeoff between the achieved parameters and the writing speed is discussed for selected set of writing strategy algorithms.

On the boundary conditions in the numerical simulation of stably stratified fluids flows
Bodnár, Tomáš; Fraunié, P.
2017 - English
This paper presents the results of a numerical study of the stably stratified flow over a low smooth hill. The emphasize is on certain problems related to artificial boundary conditions used in the numerical simulations. The numerical results of three-dimensional simulations are shown for a range of Froude and Reynolds numbers in order to demonstrate the varying importance of these boundary issues in different flow regimes. The simulations were performed using the Boussinesq approximation model solved by a high-resolution numerical code. The in-house developed code is based on compact finite-difference discretization in space and Strong Stability Preserving Runge–Kutta time integration. Keywords: Boussinesq approximation; stable stratification; compact finite-difference Available on request at various institutes of the ASCR
