Burial Mounds

The Valley of the Kings in Tuva Republic, southern Siberia, is arguably one of the most important archaeological landscapes in the eastern Eurasian steppes. Nonetheless, little information exists about the spatial characteristics and preservation conditions of this burial ground consisting of large “royal” mounds. We map the large monuments of the Uyuk Valley’s northern river terrace and assess their state of preservation based on high-resolution optical satellite data. The burial site consists of several hundred mounds, over 150 of them with diameters of more than 25 m, the largest monuments are bigger than 100 m in diameter. This makes the Valley of the Kings in Tuva Republic one of the largest Early Iron Age burial sites in the Eurasian steppes. Unfortunately, around 92% of the large monuments are in bad condition, mostly due to looting.

Статья продолжает серию публикаций по результатам технико-технологического анализа керамики памятников раннего железного века Томского Приобья, относящихся к шеломокской культуре и к томскому варианту кулайской культурно-исторической общности. Для анализа были взяты фрагменты керамики из могильника Шеломок I, поселений Кижирово и Самусь II. Результаты анализов показали, как сходство, так и отличия в выборе исходного сырья и подготовки формовочных масс. Например, если для поселения Шеломок II – базового памятника шеломокской культуры, характерна примесь дресвы из гранита с белыми и прозрачными включениями кварца (Плетнёва, Степанова, 2018), то в формовочных массах керамики из могильника добавляли гранит с красными (розовыми) включениями кварца. Памятники эти расположены рядом, на расстоянии 500 м друг от друга, то есть природная среда была одинаковой. Датировка поселения Шеломок II укладывается в пределы V–III вв. до н. э., а могильника Шеломок I – IV–III вв. до н. э., что свидетельствует об их синхронном существовании. Предметы из могильника находят ближайшие аналогии в материалах шеломокской культуры. Сравнение предметного ряда изделий из бронзы, кости и рога свидетельствует о контактах оставившего его населения с тагарцами Ачинско-Мариинской лесостепи, а также, возможно, с населением большереченской культуры, по мнению И. Ж. Рагимхановой и возможно, по мнению Л. М. Плетневой, материалы могильника отражают сложные культурные процессы раннего железного века, происходившие в Томском Приобье и фиксируют приход населения из Ачинско-Мариинского района тагарской культуры.This paper continues a series of publications that report the results oftechnical and technological analysis of ceramics from the Early Iron Age monuments of the Tomsk Ob Region, which are attributed to Shelomok and Tomsk variants of the Kulay cultural and historical community. Fragments of ceramics have been taken for analysis from the Shelomok I burial ground, Kizhirovo and Samus II settlements. The results of analysis demonstrate both similarities and differences in the choice of raw materials and the preparation of molding compounds. For example, the addition of granite gruss with white and transparent quartz inclusions to the pottery paste was typical of Shelomok II settlement (Pletneva, Stepanova, 2018), while the pottery paste from the burial ground included granite with red (pink) quartz inclusions. These monuments are located nearby, at a distance of 500 m away from each other, in the same natural environment. Perhaps, the materials of the burial ground reflect the complex cultural processes of the early Iron Age that took place in the Tomsk Ob region and record the arrival of the population from the Achinsk-Mariinsky district of tagar culture.

Hydroxyapatite/Chitosan (HAp/CS) bio-coatings were prepared on the surface of carbon/ carbon (C/C) composites by hydrothermal electrophoretic deposition, using sonochemical process resulted HAp nanoparticles, isopropyl alcohol and chitosan as raw materials. The influences of hydro- thermal conditions and deposition voltage on the microstructures and morphologies of the as-prepared coatings were investigated. It was shown that homogenous and dense HAp/CS coatings on C/C composites are obtained by hydrothermal electrophoretic deposition. With the increase of deposition voltage, density and homogeneity of the as-prepared HAp/CS composite coatings are well improved. Due to the growth of HAp nanoparticles in the hydrothermal condition, the subsequent heat treatment of the HAp/CS coatings is not needed.

The anthropological composition of the population buried at the cemetery of the Scythian Age near Svitlovodsk city (Kirovograd region) is analyzed in the paper. The burial ground is located on the border of the Forest-Steppe and Steppe Zones of the Right Bank of the Dnieper. The anthropological material under study comes from cemetery without mounds. Archaeologists date the main massif of burials to the 4th century BC. The anthropological composition of the population that was buried at this burial ground was not homogenous. The male series of skulls is characterized by a long, medium-wide, high, dolichocranic skull. The face is of medium size, it is mesognathic. The horizontal profile of the face at the upper level is medium, but with a tendency to the sharp; at the middle level, the face is strongly profiled. The orbital and nasal indexes are medium. The bones of the nose are moderately protruding. The average characteristics of the male population fit into the range of variations of the Scythian series. The male series belongs morphologically and statistically to the circle of the steppe Scythian groups. The male group from the burial ground near the city of Svitlovodsk is close to the series from the Nikolaevka burial ground on the Dnister River, the group of skulls from the burial mounds near the village of Shirokoe (Left Bank of the Dnieper River), the group of skulls from the burial mounds near the village of Vyshchetarassivka, a series of skulls from the Mykhailivka burial ground. Of the forest-steppe series, only the combined group of skulls from the Trypillya region is somewhat close to it. All these statistically and morphologically similar groups originate from different territories. This illustrates the specifics of the settlement and demonstrates the mobility of the Scythian groups. The female series from the burial ground is characterized by a long, narrow, medium-high skull, mesocranic in shape. The size of the face is small, it is mesognathic. The horizontal profile of the face at the upper level is moderate, at the zygomaxilar level it belongs to the category of sharp, but with a tendency to moderate. The orbital index is medium, the nasal index belongs to the large category. The bones of the nose are medium protruding. The female series from Svitlovodsk burial ground turns out to be the most gracile among the Scythian series in Ukraine. For this reason, it differs significantly from the entire massif of the steppe Scythian series. The closest to the Svitlovodsk series is a group from mounds near Nikopol.

The article analyzes the pottery Plotnikovo burial ground, which belongs to the Rodanovskaya culture. Material culture this time has not been well studied. Finds discovered during the excavations, it was quite diverse. Jewelry, weapon, tools and household items represent it. Some things are similar to the materials of the Russian North, the Volzhskaya Bulgaria and Perm Vychegodskaya. The study was conducted typological and technological analysis of the fragments of 52 vessels. For the site is characterized by proliferation of cup-shaped vessel with a flattened bottom and a loop handle, weak ornamentation dishes with the prevalence of the use of a comb stamp for applying the patterns, the use of clay in the wet state with the addition of crushed shells in the molding composition. A comparison with ceramic complexes chronologically simultaneous sites Vymskaya and Chepetskaya culture revealed both similarities and differences. These differences indicate the presence of its own tradition of producing ceramics in funerary XII-XV centuries of the population, left the Plotnikovo burial ground. The study material of the Plotnikovo burial ground is great interest to address the issues of ethno genesis Permian Komis and clarify the chronology of late stage rodanovskaya culture.

To reconstruct the technological methods and technical achievements of Northern Selkup blacksmiths, the components of the Northern Selkup shaman costume, which is composed of ferrous metal, were studied using metallographic analysis methods. The materials were found in two graves in a Kikki-Akki burial ground from the XVII–XVIII centuries (Western Siberia, Taz river). It was found that the basic raw materials for production were unevenly carbonized steel and soft iron; high-carbon steel was also found in rare instances, which was most likely received by Northern Selkup blacksmiths from Russia. The iron items of the shaman costume were forged by professional blacksmiths who possessed complex technological skills and production equipment.

The paper introduces the first results of special technical and technological investigation of ceramic artifacts discovered during the excavations of the Early Bronze Age settlement Shauke 1 located in the Pavlodar Region of North-East Kazakhstan. The research of ceramic objects is conducted within historical and cultural approach following A.A. Bobrinskys technique. 53 samples from different vessels were selected for the technological analysis of ceramic artifacts found at the settlement. The samples were investigated with the use of a binocular microscope MBS-10. The main objective of the research was to identify cultural traditions at a preparatory stage of ceramic vessels production. The author studied initial raw materials selection skills and forming substance preparation. The author recorded the use of several conditional spots as sources of raw materials. Six different recipes of forming substances were identified at the settlement of Shauke 1. The most common amongst them are clay + chamotte + organic solution (60,38%), clay + chamotte + bone + organic solution (28,30%). This indicates the presence of artisans who followed different traditions of pottery production at the site.

Introduction. The article substantiates the need for high-temperature processing of feed ingredients. Principles of operation and design features of the applied methods and equipment for feed production are considered. Phase transitions, along with advantages and energy, technological, and technical drawbacks are highlighted. The aim of the study is to justify a possibility of creating high-efficiency production lines using heat treatment of feeds by application of heat valves ensuring continuous loading of raw materials into a reactor and discharge of the treated feed at high pressures and temperatures. Materials and Methods. It is proposed to transfer the process of barothermal processing to a higher zone of the phase diagram of the system p,t (pressure and temperature). This is a section of the superheated steam zone with temperature 300–374 °C, pressure 12–21 MPa and treatment exposure 30–60 seconds, which replaces costly processes of normalizing, expansion, extrusion and granulation. The change in enthalpy in the pressure range 0–21 MPa and temperature range 0–600 °C is shown. Thermal modes are presented as formulas which is the basic condition for the use of digital technologies. Results. The design of the reactor with a thermal gate for loading and unloading, being the main unit of the production line of the feed heat treatment, was proposed. The results of the study are fundamental for the development of the sample flow low-capacity line. Discussion and Conclusion. The transfer of the process of barothermic processing of feed into the zone of superheated steam allows for the transfer of poorly digestible elements of grain and legumes in easily digestible, pathogen-free feed. Advantages of the reactor and line include the user-friendly design, energy saving and possibility of implementation of advanced digital technologies.
