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
