Světlá výška v nejvyšším bodě je 15,3 m. Nosnou konstrukci tvoří sloupy a obloukový příhradový vazník. Vzdálenost jednotlivých příčných vazem je 6 m. V návrhu konstrukce jsou řešeny čtyři varianty příčného rámu. Pro vybranou variantu je nadále zpracován statický výpočet hlavních nosných prvků včetně vybraných detailů a výkresová dokumentace.The bachelor’s deal with supporting with steel structure sports hall. As the mean material of bering elements was designet steel S235. The building has an rectangular shape with dimensions of 36x48 m. Clear hight at the highest point is 15,3 m. The supporting structure consist of colums and arched truss girder. The distance of each cross links sis 6 m. In the structure design is deal with four variant transversál frames. For the chosen variant is further processed a static calculation of the main structrual elements including selected details and drawing documentation.

The Beaker phenomenon and the genomic transformation of northwest Europe

From around 2750 to 2500 bc, Bell Beaker pottery became widespread across western and central Europe, before it disappeared between 2200 and 1800 bc. The forces that propelled its expansion are a matter of long-standing debate, and there is support for both cultural diffusion and migration having a role in this process. Here we present genome-wide data from 400 Neolithic, Copper Age and Bronze Age Europeans, including 226 individuals associated with Beaker-complex artefacts. We detected limited genetic affinity between Beaker-complex-associated individuals from Iberia and central Europe, and thus exclude migration as an important mechanism of spread between these two regions. However, migration had a key role in the further dissemination of the Beaker complex. We document this phenomenon most clearly in Britain, where the spread of the Beaker complex introduced high levels of steppe-related ancestry and was associated with the replacement of approximately 90% of Britain’s gene pool within a few hundred years, continuing the east-to-west expansion that had brought steppe-related ancestry into central and northern Europe over the previous centuries

RP technology using FDM method and investment casting technology

Stanovení přesnosti voskových modelů je důležitým krokem v širším uplatnění metod rychlého prototypování v průmyslové výrobě odlitků. Výsledkem této práce je srovnání stupňů přesnosti voskových modelů, vyrobených ve formě silikonové a v matečné kovové formě, které se dále využijí v přesném lití. Výsledkem experimentu je zjištění, že modely vyrobené pomocí metod rychlého prototypování jsou pouze o jeden až dva stupně přesnosti horší něž modely vyrobené ve formě kovové.Determining accuracy of wax patterns is an important in wide implementing rapid prototyping methods in investment casting. This experiment is comparing wax pattern accuracy produced in classical metal die and silicone mould. It has been found out, that wax patterns produced by the silicone mould are ounly about one or two accuracy steps worse then wax patterns produced by classical metal die.

Reconstruction of diet of population from Roman period (1st-4th c. A.D.) on Pruszcz Gdański cemetery material

The cemeteries of the Wielbark culture in Pruszcz Gdański date back to the beginning of our era. Their location near the Baltic Sea suggests some connection with Germanic tribes. In an attempt to reconstruct the diet of the buried there, 182 bone samples were taken from 48 skeletons there and subjected to analysis for chemical elements. The data show the bone samples had a zinc-dominant microelement composition that has been also observed at Germanic burial places situated along the frontier of the Roman Empire. Our supposition is that the diet of the population was dictated by their customs rather than by the natural environment conditions there

Ancient human parvovirus B19 in Eurasia reveals its long-term association with humans.

Human parvovirus B19 (B19V) is a ubiquitous human pathogen associated with a number of conditions, such as fifth disease in children and arthritis and arthralgias in adults. B19V is thought to evolve exceptionally rapidly among DNA viruses, with substitution rates previously estimated to be closer to those typical of RNA viruses. On the basis of genetic sequences up to ∼70 years of age, the most recent common ancestor of all B19V has been dated to the early 1800s, and it has been suggested that genotype 1, the most common B19V genotype, only started circulating in the 1960s. Here we present 10 genomes (63.9-99.7% genome coverage) of B19V from dental and skeletal remains of individuals who lived in Eurasia and Greenland from ∼0.5 to ∼6.9 thousand years ago (kya). In a phylogenetic analysis, five of the ancient B19V sequences fall within or basal to the modern genotype 1, and five fall basal to genotype 2, showing a long-term association of B19V with humans. The most recent common ancestor of all B19V is placed ∼12.6 kya, and we find a substitution rate that is an order of magnitude lower than inferred previously. Further, we are able to date the recombination event between genotypes 1 and 3 that formed genotype 2 to ∼5.0-6.8 kya. This study emphasizes the importance of ancient viral sequences for our understanding of virus evolution and phylogenetics

137 ancient human genomes from across the Eurasian steppes.

For thousands of years the Eurasian steppes have been a centre of human migrations and cultural change. Here we sequence the genomes of 137 ancient humans (about 1× average coverage), covering a period of 4,000 years, to understand the population history of the Eurasian steppes after the Bronze Age migrations. We find that the genetics of the Scythian groups that dominated the Eurasian steppes throughout the Iron Age were highly structured, with diverse origins comprising Late Bronze Age herders, European farmers and southern Siberian hunter-gatherers. Later, Scythians admixed with the eastern steppe nomads who formed the Xiongnu confederations, and moved westward in about the second or third century BC, forming the Hun traditions in the fourth-fifth century AD, and carrying with them plague that was basal to the Justinian plague. These nomads were further admixed with East Asian groups during several short-term khanates in the Medieval period. These historical events transformed the Eurasian steppes from being inhabited by Indo-European speakers of largely West Eurasian ancestry to the mostly Turkic-speaking groups of the present day, who are primarily of East Asian ancestry
