Forecasting assessment of phenotypical features of ethnoteritorial groups of the Prykarpattya

The issue related to the study of anthroposcopic, anthropometric, dermatoglyphic parameters of the population of Ukraine to create regional gene pools remains relevant, because given the intensification of migration processes both within Ukraine and worldwide. The growing flow of global migration and assimilation creates all the conditions for the disappearance of pure ethnic groups and peoples. This work highlights the prospects for studying the ethnic and regional features of human anthroscopic parameters. The article presents the differential anthroscopic characteristics of Hutsul, Boyko, Lemko, Opollia, Pokuttia ethno-territorial groups. The goal of the work. To form anthroscopic portraits of Hutsul, Boyko, Lemko, Opollia, Pokuttia ethno-territorial groups in comparison with the control group of persons. Materials and methods. The material of the study was anthroscopic parameters of 480 males and females aged 18-59 years, belonging to the Hutsul, Boyko, Lemko, Opollia, Pokuttia and control groups, obtained by questionnaires using standardized methods proposed by Ginsburg BB (1963). The obtained data were subjected to statistical analysis. Results. Anthroposcopic portrait of the studied groups: Hutsul ethno-territorial group is characterized by dark skin tone, black straight hair, oval elongated straight face, dark brown or green-brown eyes, long narrow nose; Boyko ethno-territorial group is marked by white skin color, blond straight or wavy hair, round broad face, gray or dark brown eyes, wide straight nose; the Lemko ethno-territorial group is distinguished by white skin color, light straight or curly hair, oval elongated narrow long face, light brown and blue eyes, narrow straight nose; Opole ethno-territorial group is characterized by white skin color, light blond and dark blond wavy hair, round broad face, dark brown and light brown eyes, straight wide nose; The Pokut ethno-territorial group is distinguished by white skin, black and dark blond straight hair, an oval elongated narrow face, brown-green eyes, and a long narrow nose. Conclusion. We were able to apply the obtained results in practice, including in the set of identification features and developing an algorithm for rapid prediction of human outward signs.

FORMATION OF THE ANTHROPOLOGICAL COMPOSITION OF THE POPULATION OF UKRAINE IN COSSACK TIME. STEPPE IMPACT

The anthropological type of Ukrainians of Cossack Era was formed on the Old Rus anthropological substrate. They were mostly descendants of the inhabitants of former lands of Drevlyani, Volynyani, Tivertsy and partly Galichani. They were characterized by a combination of a broad face with a dolichocranial or mesocranial skull. People from non-Slavic groups, including ones from the steppe zone, also took part in the formation of the anthropological composition of the late medieval population of Ukraine. Mostly it was a population that was genetically related to the groups that had ancient roots in the Turkic-speaking world. It was characterized by a Zlivkin morphological complex (brachycranium, a relatively broad face that had a weakened horizontal profile at the top). The type is Caucasian, it was widespread in large areas occupied by the Saltovo-Mayatska culture. It was characteristic for the population of Khazaria, the medieval cities of Crimea, the plains of the North Caucasus, the southern Bulgarians. For the population of Volga Bulgaria, the appearance of this morphological complex is associated with the movement of the early Bulgarians genetically related to the Sarmatians. The type continued to dominate in some areas during the Golden Horde and after the Golden Horde Age. Its presence is recorded in the south of Ukraine and in Moldova. The infiltration of the descendants of this population into the Slavic environment of Ukraine took place in different ways. The source territories for it could be the Lower Dnieper and the Prut-Dniester interfluve. The time of infiltration is most likely the second half of the 13th—15th centuries. Single skulls which are characterized by a tall face with a sharp horizontal profile and can be associated with people from the North Caucasus are recorded in the late medieval cemeteries of Ukraine. Skulls with clearly defined Mongoloid features practically are not found in the late medieval Christian cemeteries of Ukraine. Groups of nomads with these features (from Cumans to Nogai Tartars) are anthropologically differ as far as possible from the population of Cossack Era Ukraine, which was buried in Christian cemeteries.

Anthropological reconstruction of the physical appearance of the «king» and «queen» from the early Scythian burial and memorial complex of Arzhan-2

Arzhan-2, the archaeological site of world significance, a national treasure of peoples of Tuva and Russia, located in the «Valley of Kings» (Piy-Khemsk District, Tyva Republic), was investigated in 2001–2004 by the Central Asian Archaeological Expedition of the State Hermitage Museum headed by K.V. Chugunov. The sites has been dated to the 7th c. BC and attributed to the Scythian-Siberian cultural community. When exploring the «royal» burial of the early Scythian site of Arzhan-2, the scientists faced the questions of the origin of the buried, periodization and chronology of the monument, its archaeological-cultural attribution, the autochthonous nature of the population that left it, and its relationship with other Eurasian early nomadic cultures. The present study is addressing the most important issue of the appearance of the buried people and characteristics of their anthropological type. The material for the study was comprised of male and female skulls from burial 5 of Arzhan-2 mound. The article describes in detail the process of reconstruction of the physical appearance of the deceased and provides examples of calculating ante mortem parameters based on craniometric measurements. The complex stages of preliminary work related to the restoration of skulls and manufacturing of their exact copies are highlighted. The results of the physical appearance reconstruction are presented in the form of visual museum objects — sculptural portraits. The scientific reconstruction of the ante mortem appearance on skulls of the «king» and «queen» was carried out in the Laboratory of Anthropological Reconstruction of the Institute of Ethnology and Anthropology of the Russian Academy of Sciences by anthropologists Drs E.V. Veselovskaya and R.M. Galeev. In anthropological terms, the buried show a peculiar mosaic of Caucasoid and Mongoloid features. They are characterized by brachycephaly and dome-shaped head, with notably developed rugosity of the supercilium in the man and its absence in the woman. For the man, an average width of the face and a narrow forehead of medium height are noted. The woman has broad face and forehead, the height of the forehead is average. Both portraits are characterized by prominent position of eyeballs and large eyes. Man’s nose is short, prominent, with convex dorsum. Woman’s nose has a wavy dorsum, and is slightly prominent. On the male portrait, the cheekbones are moderate, on the female one — high and prominent. Faces of the «royal» persons are flattened in the upper part, with a certain degree of alveolar prognathism. The lower jaw of the man is medium in size, narrow in the corners. For the woman, some gracility of the lower jaw can be noted.

SEX-RELATED FEATURES OF THE ASYMMETRY OF CRANIOMETRICS PARAMETERS IN VARIOUS FORMS OF THE FACIAL SKULL

The aim was to study the severity of asymmetry on different forms of the facial skull with regard to gender. It was studied 70 specially selected turtles of people of different ages from the craniological collection of the fundamental museum of the human anatomy department of the Azerbaijan Medical University. The characteristic of the group of skulls that was study was carried out on the basis of the upper index of the face. To study the asymmetry of the facial skull, the fan-shaped method of morphometry was used. The digital data of our study were subjected to statistical processing. An analysis of the data obtained indicates the absence of statistically significant sexual differences in the sizes of the contralateral sides of all the studied parameters of the upper fan for skulls with different face shapes. In the women's series on the lateral fan the asymmetry is almost negligible. In the men's series, almost all indicators on the lateral fan show stable left-sided asymmetry. The exception is the distance from the zygo-maxillary point to the lowest point of the pear-shaped hole. In the lower fan on the turtles with a narrow and broad face in the female series of skulls, left-sided asymmetry is observed in almost all signs. On turtles with a face of medium width, both significant left-sided and right-sided asymmetry are noted. In the male series, in general, the asymmetry is much less pronounced than in the female series of skulls. The exception is the subspinal-dacryon distance on wide-faced skulls in the male skull series was found right-sided asymmetry, which is not typical for the female series.

Developmental changes in the processing of faces as revealed by EEG decoding

Rapidly and accurately processing information from faces is a critical human function that is known to improve with developmental age. Understanding the underlying drivers of this improvement remains a contentious question, with debate continuing as to the presence of early vs. late maturation of face-processing mechanisms. Recent behavioural evidence suggests an important ‘hallmark’ of expert face processing – the face inversion effect – is present in very young children, yet neural support for this remains unclear. To address this, we conducted a detailed investigation of the neural dynamics of face-selective processing in children spanning a range of ages (6 – 11 years) and adults. Uniquely, we applied multivariate pattern analysis (MVPA) to the electroencephalogram signal (EEG) to test for the presence of a distinct neural profile associated with canonical upright faces when compared both to other objects (houses) and to inverted faces. Results revealed robust discrimination profiles, at the individual level, of differentiated neural activity associated with broad face categorization and further with its expert processing, as indexed by the face inversion effect, from the youngest ages tested. This result is consistent with an early functional maturation of broad face processing mechanisms. Yet, clear quantitative differences between the response profile of children and adults is suggestive of age-related refinement of this system with developing face and general expertise. Standard ERP analysis also provides some support for qualitative differences in the neural response to inverted faces in children in contrast to adults. This neural profile is in line with recent behavioural studies that have reported impressively expert early face abilities during childhood, while also providing novel evidence of the ongoing neural specialisation between child and adulthood.

δ-Hydride Habit Plane Determination in α-Zirconium at 298 K by Strain Energy Minimization Technique

Hydrogen in excess of solid solubility precipitates as hydride phase of plate shaped morphology in hcp α-Zr with the broad face of the hydride plate coinciding with certain crystallographic plane of α-Zr crystal called habit plane. The objective of the present investigation is to predict the habit plane of δ-hydride precipitating in α-Zr at 298 K using strain energy minimization technique. The δ-hydride phase is modeled to undergo isotropic elasto-plastic deformation. The α-Zr phase was modeled to undergo transverse isotropic elastic deformation but isotropic plastic deformation. Accommodation strain energy of δ-hydride forming in α-Zr crystal was computed using initial strain method as a function of hydride nuclei orientation. Hydride was modeled as disk with round edge. Contrary to several habit planes reported in literature for δ- hydrides precipitating in α-Zr crystal, the total accommodation energy minima at 298 K suggests only basal plane i.e. (0001) as the habit plane.
