This paper discusses the phenomenon of mammoth ivory necklaces from Dolní Věstonice I (Moravia, Czech Republic). The ivory artefacts were described by the excavator K. Absolon in 1937 as necklaces, and this primary interpretation is still in use today. In this case, mammoth ivory was worked into repeating standardised forms of various size, which are almost absent elsewhere in the Upper Palaeolithic. The seven artefacts were here examined for their state of conservation, manufacturing technology, decorating style and supposed functional purpose. Partial reconstruction of the chaîne opératoire can enable integration of these artefacts into the style of mammoth ivory processing at this Gravettian site, and help to define the status of this raw material. © 2014 Elsevier Ltd and INQUA.

The first excavated Palaeolithic site of Bohemia was Lubná, where J. Kušta in 1890 excavated station I. At least seven other sites (Lubná II to VIII) were discovered in its vicinity over time, making the Lubná area the richest site cluster in Bohemia. It is also the only place in Bohemia where several stations are located in a small area. All sites belong to the Upper Gravettian period, dated to 25 to 21 ka BP.For comparison of Lubná sites, there are 3646 artefacts from 6 sites in Lubná. The largest assemblage is Lubná III with 1442 artefacts; the second largest is the assemblage of Lubná II with 952 artefacts. Lubná IV has 566 artefacts and Lubná I 460 artefacts. The smallest assemblages come from sites Lubná VI and VIII (162 and 64 artefacts).Dominant raw materials are silicites of glacial sediments from the north (Silesia and Saxony). There are small amounts of quartzites of northwestern Bohemia and Bavarian plattensilex.All sites have very low amount of cores, and they show high stages of exploitation. Microchips, flakes and burin spalls demonstrate blade and tool production on sites. Tool composition is typical for the Gravettian with gravettian points and micropoints, domination of burins, and numerous microliths. Kostenki points are absent. Pavlovian microliths, triangles and segments, are present. © 2015 Elsevier Ltd and INQUA. Source

The aim of this paper is to describe the help of simulation as should look like expansion of production in the manufacturing plant. The establishment of a simulation models, we used a software product from Siemens PLM Software and Tecnomatix Plant Simulation. The paper describes the current production model, which the principle for is the extension of production planning. Using a simulation model is drawn up to include layout work on a planned workforce newly built production line at the company. The introduction is described some basic concepts. When analyzing business processes and developing their models clarified are some procedures work in Plant Simulation software module. © 2014 Published by Elsevier Ltd. Source

A multi proxy approach was applied in the reconstruction of the architecture of Medieval horse stable architecture, the maintenance practices associated with that structure as well as horse alimentation at the beginning of 13th century in Central Europe. Finally, an interpretation of the local vegetation structure along Morava River, Czech Republic is presented. The investigated stable experienced two construction phases. The infill was well preserved and its composition reflects maintenance practices. The uppermost part of the infill was composed of fresh stabling, which accumulated within a few months at the end of summer. Horses from different backgrounds were kept in the stable and this is reflected in the results of isotope analyses. Horses were fed meadow grasses as well as woody vegetation, millet, oat, and less commonly hemp, wheat and rye. Three possible explanations of stable usage are suggested. The stable was probably used on a temporary basis for horses of workers employed at the castle, courier horses and horses used in battle. © 2014 Dejmal et al. Source
