- Description:
- The Czech ''Silesian identity'', obvious throughout the twentieth century, was based on a mixture of strong regional, even local, patriotism, which was determined by historical developments. This patriotism developed on the ethnically mixed territory of Czech Silesia (formerly Austrian Silesia). After the Second World War, this phenomenon was quickly revived, but unlike in the pre-war period, it took a clearly Czech national form. The territorial factor, by contrast, receded into the background. Behind this activity and new interpretation stood intellectual circles and institutions in Opava, some leading fi gures from Ostrava, and the Silesian Cultural Institute in Prague. In addition to cultural-educational activity, their efforts were concentratedon claiming some border areas of Polish and German Silesia as being historically Czech, and also on ensuring the distinctive administrative status of the territory of Silesia in Czechoslovakia, the seed of which they saw in the Ostrava branch of the Moravian National Committee (Zemský národní výbor) in Brno. During the Communist regime, according to the authors, the top state authorities showed an intentional lack of interest in the problems of Silesia when solving related economic and other questions. A consequence of this was a ''silencing of the offi cial sources'' about Silesia. In the 1950s, the ''Silesian-ness'' was condemned as a form of ''bourgeois nationalism'' and was identifi ed with the period of Czech-Polish national friction in the region. From the administrative point of view, Silesia was dissolved in the Ostrava area, later in the North Moravian Region, and was recalled practically only by artistic expressions of an ''Old Silesian-ness'', such as folklore and museum exhibitions. Silesian organizations and societies were, with few exceptions, dissolved or renamed and the newly established Silesian Research Institute in Opava had to orient its historical research chiefl y to the labour movement. The works of the poet Petr Bezruč (born Vladimír Vašek, 1867-1958) and his collection of verses, Slezské písně (Silesian Songs), presented a problem because of their questionable depiction of Silesian identity, and the publication of the complete collection led to disputes in cultural policy. The Ostrava-based arts and politics periodical Červený květ (Red Flower), which repeatedly included debates about regionalism, began to be published in the mid-1950s. At the end of the decade, however, the Communist Party launched a campaign against parochialism (lokálpatriotismus), which was refl ected also in the condemnation of publications seeking to exonerate the poems and ideas of Óndra Łysohorsky (born Ervín Goj, 1905-1989), who during the war promoted the theory of a ''Lach nation.'' In the 1960s, the local authorities and fi gures of Opava again began to emphasize the role of their town as a regional centre. During the Prague Spring of 1968, there were calls for the restoration of Silesian self-government, but that remained more or less limited to the Opava region, and consequently some ''Silesian'' cultural initiatives from this period were of greater importance.

- Description:
- To investigate how excess excitation energy is dissipated in a ribulose-1,5-bisphospate carboxylase/oxygenase activase antisense transgenic rice with net photosynthetic rate (PN) half of that of wild type parent, we measured the response curve of PN to intercellular CO2 concentration (Ci), electron transport rate (ETR), quantum yield of open photosystem 2 (PS2) reaction centres under irradiation (Fv'/Fm'), efficiency of total PS2 centres (ΦPS2), photochemical (qP) and non-photochemical quenching (NPQ), post-irradiation transient increase in chlorophyll (Chl) fluorescence (PITICF), and P700+ re-reduction. Carboxylation efficiency dependence on Ci, ETR at saturation irradiance, and Fv'/Fm', ΦPS2, and qP under the irradiation were significantly lower in the mutant. However, NPQ, energy-dependent quenching (qE), PITICF, and P700+ re-reduction were significantly higher in the mutant. Hence the mutant down-regulates linear ETR and stimulates cyclic electron flow around PS1, which may generate the ΔpH to support NPQ and qE for dissipation of excess excitation energy. and S.-H.

- Subject:
- CPT, Bayesian network, crowdsourcing, human computation, exercise instructions, collective intelligence, and automatic update
- Language:
- English
- Description:
- Physical exercise instruction sheets are difficult to understand. In general, considerable information is hidden in these types of instruction sheets, which also makes them difficult for machines to understand. Major missing information types include the source and destination location of a human movement. Here we present a Bayesian network to extract the implicit or missing information from typical exercise instruction sheets. We proposed two different kind of Bayesian networks which consists of three and four variables respectively. The network with three variable are designed to for single exercise instruction with single action or pose and the other one designed for single or multiple sentence with two actions or poses. The conditional probability table (CPT) is the backbone of the Bayesian network. At the start, the CPT is updated from our physical exercise instruction sheet corpus (PEISC). Keeping the Action and Bodypart fixed, we have developed our CPT using a unique approach, i.e., crowdsourcing, where we have developed a CPT update system using 13 different exercises consisting of 44 different exercise videos. Using this system based on the rating of a participant of the video the specific variable of that CPT is updated automatically in the Bayesian network. We also updated the Action variable, which consists of 14 different values (action verbs) using crowdsourcing with a human computation approach.

- Description:
- The main aim of the present investigation was to verify the effects of three overtraining (OT) protocols performed in downhill (OTR/down), uphill (OTR/up) and without inclination (OTR) on the protein levels of Akt (Ser473), AMPKα (Thr172), PGC-1α, plasma membrane GLUT-1 and GLUT-4 as well as on the glycogen contents in mice gastrocnemius. A trained (TR) protocol was used as positive control. Rodents were divided into naïve (N, sedentary mice), control (CT, sedentary mice submitted to the performance evaluations), TR, OTR/down, OTR/up and OTR groups. At the end of the experimental protocols, gastrocnemius samples were removed and used for immunoblotting analysis as well as for glycogen measurements. There was no significant difference between the experimental groups for the protein levels of pAkt (Ser473), pAMPKα (Thr172), PGC-1α, plasma membrane GLUT-1 and GLUT-4. However, the OTR/up protocol exhibited higher contents of glycogen compared to the CT and TR groups. In summary, the OTR/up group increased the gastrocnemius glycogen content without significant changes of pAkt (Ser473), pAMPKα (Thr172), PGC-1α, plasma membrane GLUT-1 and GLUT-4., G. P. Morais, A.

30777. Uplatnění částice bohužel (a bohudík) v současné psané publicistice
- Creator:
- Janečka, Martin
- Format:
- bez média and svazek
- Type:
- model:article and TEXT
- Subject:
- particles, medial discourse, postural modality, semiotics, word classes, částice, mediální diskurz, postojová modalita, sémiotika, and slovní druhy
- Language:
- Czech
- Description:
- Particles as an inflexible and synsemantic word class have already become a theme of many individual studies. According to the general definition particle indicates a relation of the speaker to the statement, he/she expresses modality of the sentence or emphasizes constituent of a/the sentence. Some of the particles have the validity of sentence, e. g. Ano. Nikoli. Zajisté. So called proper particles cannot stand in the function of another word class: ať, kéž. On the contrary, improper particles can be (according with coocurence) another word class, too: jistě, asi, prý. Goal of this paper is to point in which contexts the particle bohužel, although it is a non-sentence expression, can gain the character of sentence equivalent and which functions its synonyms and antonyms have.

- Description:
- Pozměňování či falzifikace psaných textů jsou bezesporu staré jako sám vynález písma. Důvody pro takové jednání byly různé, nicméně skutečné stáří, respektive autenticita, daného rukopisu mají velký dopad na jeho význam, ať již pro historii, nebo - v případě současných rukopisů - z hlediska právního. U některých historických rukopisů je otázka jejich datování řešena s použitím spektroskopických technik, jejichž hlavní výhodou je nedestruktivnost nebo minimální invazivnost, neohrožující samu existenci zkoumaného dokumentu. V článku jsou zmíněny nejčastější spektroskopické metody používané k těmto účelům, včetně příkladů konkrétních studovaných rukopisů., The alteration or falsification of written texts is undoubtedly old as invention of scripture itself. The reasons for such behaviour are different, but the actual age or authenticity of the manuscript had a great impact on its signification, whether for history or, in the case of contemporary manuscripts, from a legal point of view. For historical manuscripts, the question of their dating is solved using spectroscopic techniques whose main advantage is non-destructiveness or minimal invasiveness, not endangering the very existence of the document under study. In the article the most frequent spectroscopic methods used for these purposes are mentioned and examples of particular studied manuscripts are given., Karel Nesměrák., and Obsahuje bibliografické odkazy
