- multiaxial stress, uniaxial fatigue criteria, mean stress, and proportional loading
- Language:
- English
- Description:
- Several multiaxial fatigue criteria have been developed and improved within the last couple of decades, but they are not very widely used in industrial applications. Many engineers and designers still use simple uniaxial criteria for multiaxial load cases. In order to test and validate / discard these uniaxial criteria on the basis of multiaxial load cases, the present work presents a comparison between several uniaxial criteria applied to a large set of experimental results for smooth unnotched samples tested under multiaxial loading. The effect of mean stress is also evaluated in order to determinate how it affects the final results. and Obsahuje seznam literatury

- Description:
- An observation network was built to observe the process of creating of a subsidence depression above exploited coal mining panels near Karviná. Points of the observation network were periodically surveyed by geodetic GPS method from 2006 to 2009. This method enables the evaluation of both vertical subsidence and horizontal shifts. Such complex evaluation of processes on the surface of the undermined area makes it possible to understand the progress of the subsidence depression caused by undermining. The results have shown on areas of irregular development of the subsidence depression. The irregularities are caused by a complicated tectonic situation and former exploitation in given locality and also active exploitation in the surroundings of given locality., Hana Doležalová, Vlastimil Kajzar, Kamil Souček and Lubomír Staš., and Obsahuje bibliografii

- Subject:
- surface water quality, physical-chemical and biological parameters, saprobix index, land-use, kvalita povrchové vody, fyzikálne-chemické parametry kvality vody, biologické ukazatele kvality vody, and saprobní index
- Language:
- Slovak
- Description:
- Water quality of the Cidlina river (right tributary of the Labe river was studied during two years (1997 - 1998). Besides the examination of hydrology and land use, the main resources of pollution were identified. Physical, chemical and biological parameters of water were measured in 10 profiles and water quality was evaluated according to Czech norms 75 7221 and put into the grade of purity. Pollution of upper part of river is not so bad but lower part is very polluted. High concentration of BOD5 correspond with biological parameters - alfa-mesosaprobita. At the end some tools and strategies are added to manage water more effectively. and V létech 1997 a 1998 byla sledována kvalita povrchové vody v Cidline (pravostranný přítok Labe). Kromě studia hydrologických parametrů a využívání krajiny (land use) byly zjištěny hlavní zdroje znečištění - města Jičín a Nový Bydžov. Fyzikálně-chemické a biologické charakteristiky vody byly měřeny na 10 říčních profilech a kvalita vody hodnocena podle CSN 75 7221 a zařazena do tříd čistoty. Horní část toku, méne znečištěná, náleží do III. - IV. třídy, silně znečištená dolní část do V. třídy čistoty. Zvýšené koncentraci BSK5 v celém toku odpovídá i kvalita makrozoobentosu - vetšinou α -mezosaprobita. V závěru jsou navržena opatření k zlepšení kvality vody.

- Description:
- Wild Arachis genotypes were analysed for chlorophyll a fluorescence, carbon isotope discrimination (ΔC), specific leaf area (SLA), and SPAD readings. Associations between different traits, i.e., SLA and SPAD readings (r =-0.76), SLA and ΔC (r = 0.42), and ΔC and SPAD readings (r = 0.30) were established. The ratio of maximal quantum yield of PSII photochemistry (Fv/Fm) showed a wider variability under water deficit (WD) than that after irrigation (IR). Genotypes were grouped according to the Fv/Fm ratio as: efficient, values between 0.80 and 0.85; moderately efficient, the values from 0.79 to 0.75; inefficient, the values < 0.74. Selected Selected genotypes were evaluated also for their green fodder yield: the efficient genotypes ranged between 3.0 and 3.8, the moderately efficient were 2.6 and 2.7, the inefficient genotypes were of 2.3 and 2.5 t ha-1 per year in 2008 and 2009, respectively. Leaf water-relation traits studied in WD and IR showed that the efficient genotypes were superior in maintenance of leaf water-relation traits, especially, under WD. Potential genotypes identified in this study may enhance biomass productivity in the semiarid tropic regions., P. C. Nautiyal, A. L. Rathnakumar, G. Kulkarni, M. S.

- Description:
- This paper considers various approaches to love and morality in Protestant society in the late 18th century, as illustrated in Czechlanguage religious and educational literature (Korunka, aneb Wjnek Pannenský wssechněm pobožným a sslechetným Pannám toho Gazyku užjwagjcým, Litomyšl 1784; Kazatel Domovnj, Brno 1783). Our focus is on divine love, man’s love of God, marital love, parental and filial love, and definitions of immorality. We also examine some contemporary reactions to religious and educational writings in the memoirs of one of their readers, the rural preacher and Bible scholar Tomáš Juren (1750-1829), as well as the differences between the Christian confessions in their attitude to the emotions., Sixtus Bolom-Kotari., and Obsahuje bibliografické odkazy

- Subject:
- protestantism, almanac, Bohemia, and 19th century
- Language:
- Czech
- Description:
- The almanacs represented an important source and constituent part of the popular culture in the „long“ nineteenth century. The text focuses on the by now slightly studied almanacs of Czech Protestants and, as a supplement, also contains its register. First Protestant calendars were published after the authorization of Protestant denominations at the end of the eighteenth century, but due to the economic weakness of these minorities soon ceased to exist. The next wave of their publishing was connected with liberalism of the middle of the nineteenth century and the social emancipation of Protestants. But the defeat of the revolution of 1848 again caused their demise. Systematic publishing of Protestant almanacs took place only in the last third of the nineteenth century, when their principal role was the gradual deepening of the confessional consciousness. From the beginning of the twentieth century these almanacs were used in the efforts for uniting of Czech Lutheran and Reformed Churches. This union was realized after the constitution of Czechoslovakia in the year 1918. Later Protestant almanacs were mostly regular ecclesiastical yearbooks without broader implications.

- The article presents a manuscript collection of texts of evangelical provenance that has recently been purchased in a German second-hand bookshop. According to a chronogram, this manuscript is likely to come from 1840. The manuscript consists of fifteen relatively independent text sections thematically related to the denominational controversies before and after the battle of White Mountain. The paper examines possible printed or manuscript models of individual parts and as well as their reflection in both earlier and more recent bibliographic literature. and David Mach.

- Language:
- Czech and English
- Description:
- The paper deals with the topic of evangelical preachers of the Helvetic and the Augsburg Confession coming from the Hungarian part of the Habsburg Monarchy, after the Patent of Toleration was issued, and establishing tolerance evangelical congregations in Bohemia and Moravia. Based on studying the sources of particular tolerance Czech congregations (for example Moraveč, Humpolec, Dvakačovice, Lozice, Raná, Sány, Prague), the process of forming a new social stratum of the petty intelligentsia, whose creation was conditioned by the Enlightenment reforms, is outlined. The text shows how the Hungarian preachers made the first contacts with the emerging evangelical communities, gives an idea of the circumstances of their arrival, describes the way of their adapting to an unfamiliar environment and their effort to stabilize the congregations. These particular findings are generalized in order to define some common characteristics typical of this group of Enlightenment intellectuals., Gabriela Krejčová Zavadilová a Hana Stoklasová., and Obsahuje bibliografické odkazy
