Bridge over the Morava river

Práce se zabývá návrhem nové mostní konstrukce na místě stávajícího mostu na silnici II/312 v obci Vlaské přes řeku Moravu. Hlavní náplní je statický výpočet nosné kontrukce o jednom poli. Byly vypracovány tři studie, z nichž byla jedna rozpracována a staticky posouzena. Most je navržen jako předpjatý deskotrámový kolmý. Rozpětí mezi podporami je 21,8 m. Statický model a účinky zatížení jsou řešeny v programu Scia Engineer a ověřeny ručním výpočtem. Účinky zatížení teplotou, větrem a vodorovných složek zatížení byly zanedbány.The thesis deals with design of a new bridge construction at the place of an existing bridge on the road II/312 in Vlaské village over the Morava river. The main topic is a static calculation of one span loadbearing structure. Three studies were made and one of them was analysed. The bridge is designed as prestressed perpendicular and combined slab-beam construction. Span length of the bridge is 21,8 m. Structural model and effect of the load were calculated in programme Scia Engineer and checked with manual calculation. Effects of temperature, wind and horizontal forces were neglected.

Seasonal variations of microbiological parameters of water quality of the Velika Morava river Serbia

In this study, we investigated the level of sanitary pollution and organic contamination of the Velika Morava River, the largest river in central Serbia. Samples of water for microbiological analysis were collected at 5 sites, monthly, from April 2010 to February 2011. Sanitary analysis, i.e. enumeration of total and fecal coliforms and intestinal enterococci, indicated moderate to critical fecal contamination, while organic load assessment (oligotroph to heterotroph ratio, index of phosphatase activity) revealed the category of moderately polluted water. We also investigated seasonal variations of these groups of bacteria and the factors that could contribute to these differences. Our results showed that the micro- biological quality of the water in the Velika Morava River during different seasons is affected by numerous factors such as unequal loading of wastewaters, solar irradiation, and relations of flow/dilution and rainfall/runoff.

Účinky zatížení od teploty, větru a vodorovné účinky od dopravy byly zanedbány.Bachelor's thesis deals with a design of one-span road bridge on road II/446 over river Morava in the village of Hanušovice. Three possible designs were developed and from these the version with two post-tensioned girders was chosen. Structural model and load effects are solved in the the Scia Engineer 2014.0. Assesments are calculated in hand according to Eurocodes. Load effects from temperature, wind and horizontal effects from traffic are not taken into account.

Study on the utilization of waters of ‘Deçani Bistrica’ river basin

The catchment in Republic of Kosova can be divided in basins of the rivers as following: Basin of Drini i Bardhë in village Radavc, Peja municipality, basin of river Ibër, Mitrovica municipality, basin of river Morava e Binçës, Gjilani municipality and basin of river Lepenci in Kaçanik municipality. The watershed of Bistrica e Deqanit, which is subject of this paper belongs to the basin of Drini i Bardhë which belongs to the Adriatic Sea catchment

Hydrological modeling with special reference to snow cover processes

A physically-based distributed hydrologic model was applied in this research. The river basin, or watershed, was discretized with a square grid, where each square carried morphological data about a portion of the watershed, the vegetation, the soil composition, the hydrogeological layer, and the like. The effect of weather stations was defined by Thiessen polygons, including correction for altitude. The hydrological model was continuous, with a one-day time step. It was partitioned into three reservoirs: vegetation, snow and soil. The snow reservoir was defined using the degree-day and temperature index methods. The hydrologic model was applied to the basin of the Banjska River, which is a tributary of the Južna Morava. [Projekat Ministarstva nauke Republike Srbije, br. 37013

The Elliptic curves in gauge theory, string theory, and cohomology

Elliptic curves play a natural and important role in elliptic cohomology. In earlier work with I. Kriz, thes elliptic curves were interpreted physically in two ways: as corresponding to the intersection of M2 and M5 in the context of (the reduction of M-theory to) type IIA and as the elliptic fiber leading to F-theory for type IIB. In this paper we elaborate on the physical setting for various generalized cohomology theories, including elliptic cohomology, and we note that the above two seemingly unrelated descriptions can be unified using Sen's picture of the orientifold limit of F-theory compactification on K3, which unifies the Seiberg-Witten curve with the F-theory curve, and through which we naturally explain the constancy of the modulus that emerges from elliptic cohomology. This also clarifies the orbifolding performed in the previous work and justifies the appearance of the w_4 condition in the elliptic refinement of the mod 2 part of the partition function. We comment on the cohomology theory needed for the case when the modular parameter varies in the base of the elliptic fibration.Comment: 23 pages, typos corrected, minor clarification

Hydrometeorological extremes derived from taxation records for south-eastern Moravia, Czech Republic, 1751–1900 AD

Historical written records associated with tax relief at ten estates located in south-eastern Moravia (Czech Republic) are used for the study of hydrometeorological extremes and their impacts during the period 1751–1900 AD. At the time, the taxation system in Moravia allowed farmers to request tax relief if their crop yields had been negatively affected by hydrological and meteorological extremes. The documentation involved contains information about the type of extreme event and the date of its occurrence, while the impact on crops may often be derived. A total of 175 extreme events resulting in some kind of damage are documented for 1751–1900, with the highest concentration between 1811 and 1860 (74.9% of all events analysed). The nature of events leading to damage (of a possible 272 types) include hailstorm (25.7%), torrential rain (21.7%), flood (21.0%), followed by thunderstorm, flash flood, late frost and windstorm. The four most outstanding events, affecting the highest number of settlements, were thunderstorms with hailstorms (25 June 1825, 20 May 1847 and 29 June 1890) and flooding of the River Morava (mid-June 1847). Hydrometeorological extremes in the 1816–1855 period are compared with those occurring during the recent 1961–2000 period. The results obtained are inevitably influenced by uncertainties related to taxation records, such as their temporal and spatial incompleteness, the limits of the period of outside agricultural work (i.e. mainly May–August) and the purpose for which they were originally collected (primarily tax alleviation, i.e. information about hydrometeorological extremes was of secondary importance). Taxation records constitute an important source of data for historical climatology and historical hydrology and have a great potential for use in many European countries

Ethics and politics of Great Moravia of the 9th century

The author studies the role of Christianity in two forms of 9th century political ethics in the history of Great Moravia, represented by the Great Moravian rulers Rastislav and Svatopluk. Rastislav’s conception predominantly uses the pre-Erasmian model of political ethics based on the pursuit of welfare for the country and its inhabitants by achieving the clerical-political independence of Great Moravia from the Frankish kingdom and, moreover, by utilising Christianity for the advancement of culture, education, literature, law and legality, as well as by spreading Christian ethics and morality in the form of the Christian code of ethics expressed in ethicallegal documents. Svatopluk’s political conception was a prototype of Machiavellian political ethics, according to which one is, in the interest of the country and its power and fame, allowed to be a lion and/or a fox. Svatopluk abused Christianity in the name of achieving his power-oriented goals. Great Moravia outlived Rastislav; it did not, however, outlive Svatopluk, as, shortly after his death, it broke up and ceased to exist. The author came to the conclusion that Rastislav’s conception was more viable, as its cultural heritage lives on in the form of works by Constantine and Methodius
