Hajdúnánás-Tedej – Lyukas-halom: egy alföldi kurgán régészeti értékelése és természettudományos vizsgálata

Kurgans are special man-made flatland formations of the endless steppe of Eurasia. The multidisciplinary excavation of Hajdúnánás-Tedej – Lyukas-halom, one of the typical Pit Grave kurgans in the Great Hungarian Plain region is presented in the paper. For centuries, archaeology has been the primary science to examine these objects. The buried soil profiles under burial mounds (kurgans) are the messengers of ancient landscape forming factors, soil generation processes and palaeobotanical patterns. Results from palaeopedology, soil micromorphology, geochemistry, palaeobotany (phytolith analysis and palynology) and archaeology are summarised in order to understand the evolution, construction and the former palaeoenvironment of the kurgan and its close vicinity. Based on the results gained from the various disciplines and the archaeological findings excavated at the kurgan the study gives an insight into the Late Copper Age and Early Bronze Age 1-2 periods including the Boleráz / Baden, Coţofeni, Pit-Grave, Makó and Nyírség cultures in north-eastern Hungary. Geochemical analysis underlines that the kurgan was built in several, separate stages. Palaeobotanical results have underlined the existence of a central ridge inhabited by (semi)xerofi l steppe vegetation and lower microrelief depressions around it. Although phytoliths have shown the possible existence of a grove-like habitat, arboreal pollen is underrepresented in the samples. This is complemented by the palaeopedological analysis of the buried soil profi le under the formation, which was identifi ed as a Chernozem soil. Palynological analysis has drawn the attention on the probable human impact in the outer skirts of the later kurgan as weed species have occurred in higher concentrations in the examined samples

Antropológiai-régészeti együttműködés a biológiai antropológiai maradványok roncsolásos mintavételének szabályozására

With the development of the new investigative techniques based on destructive or invasive sampling in biology and chemistry, a necessity to elaborate a sampling policy has emerged. As it is important to conduct research and at the same time to preserve specimens, our recommendation intends to help in deciding whether or not to grant permission for destructive sampling, bearing in mind the importance of the conservation of archaeological heritage and cultural goods (collectively “the elements of our cultural heritage”). In 2015 the Anthropological Interdisciplinary Scientific Committee (AISC), Section of Biological Sciences, Hungarian Academy of Sciences (SBS, HAS) appointed a working group to give recommendation for a Destructive Sampling Protocol for Biological Anthropological Remains. The Recommendation was drawn up by this working group, named “Committee for Preparation Destructive Sampling Protocol of Biological Anthropological Remains” of the AISC, SBS, HAS, with the contributions of physical anthropologists and archaeologists of several institutes and museums, and the members of the Archaeological Scientific Committee, HAS. The Recommendation was read and approved by the Committee of Anthropology, SBS, HAS and Archaeological Scientific Committee, HAS, in 2017

Vibrations of fixed-fixed heterogeneous curved beams loaded by a central force at the crown point

This paper addresses the vibrations of heterogeneous curved beams under the assumption that the load of the beam is a dead one and is perpendicular to the centroidal axis. It is assumed that: (a) the radius of curvature is constant, and (b) Young’s modulus and the Poisson’s number depend on the cross-sectional coordinates. As for the issue of fixed-fixed beams, the objectives are the following: (1) to determine the Green’s function matrices provided that the beam is under radial load; (2) to examine how the load affects the natural frequencies given that the beam is subjected to a vertical force at the crown point; (3) to develop a numerical model which makes it possible to determine how the natural frequencies are related to the load. The computational results are presented graphically
