The article is devoted to the discussion of the processes of interaction between the population of Neolithic and Eneolithic cultures in the Upper and Middle Don basin. A.T. Sinyuk considered these processes within the framework of «Neolithic survival», A.M. Skorobogatov and A.V. Surkov propose to single them out into a special Neo-Eneolithic stage. The use of the new term does not solve the problem and does not contribute to a better understanding of the situation. There are no metal finds on the settlements of Don forest-steppe area, and the studied burials are few. The topography of the Sredny Stog settlements does not differ from the location of local Neolithic sites. The osteological materials from the Upper Don settlements named Vasilyevsky cordon 17 and 27 indicate that the leading place in the Eneolithic economy was occupied by hunting and fishing. And at the Middle Don settlement of Cherkasskaya 5 domestic animals were known already in the Neolithic Age. The layers with Sredny Stog`s pottery are usually found on the same monuments as Neolithic materials. A prerequisite for the conflict-free coexistence of different groups within a limited area is their orientation towards different sources of food, connected with the development of different natural and economic resources. There were no conditions for the parallel development of the population with different economic and social patterns in the Don region. Migrants and aborigines came into close contact with each other, which was reflected in the emergence of hybrid ceramic materials. The processes described above represent a particular case of transition from the stone age to the metal age, the content of which fully corresponds to the definition of Eneolithic.

6Contemporary science and culture show more and more extended and meaningful signs about the increasing explaining power of evolutionary paradigm. This power overcomes the field of the history of living species. We consider “On the Origin of Species” of 1859 by Charles Darwin as the establishment of this paradigm, but this original and fruitful idea has received the several and different contributions from near and (seemingly) far scientific fields. This process happened according distinguishable waves and leaded the evolutionary theory very far from its starting point, making it something wider and different. The current knowledge of this theory involves many kinds of scholars: biologists, zoologists, botanists, development biologists, genetics/genomics scholars and also scholars of many other disciplines, as statistics, mathematics, ecology, environmental sciences, physics, chemistry, linguistics, sociology, neuro-sciences, epidemiology, informatics, immunology. During the end of XX Century, the study of complexity, of self-organization and of emerging properties has been a decisive factor to extend evolution until beyond the boundaries of Biology. These phenomena, or properties, or features, that are shown by “living” and “not-living” systems (so called basing ourselves on traditional definitions), have deeply modified even the “properly” biologic evolution itself and besides this has demonstrated that, mutatis mutandis, evolutionary processes or phenomena happen also out of biologic dominion, referring “biologic” to “wet-ware world”. This is to say the class of evolutionary phenomena is more widely and more inclusively extended than our opinion. We can mean this as a revolution (according to Kuhn’s definition) that imposes us to restructure the definition of evolution itself and even to redraw the boundaries and the map of Biology itself. Aiming to establish a name of this field of study we propose “PanEvolutionary Theory” (PanEvo Theory). No doubt Prigogine offered an important contribution to this area. The thinking and the work of Enzo Tiezzi can be placed seen in the same perspective. Disregarding direct connections and contacts with the Nobel Prize Prigogine, however the studies of Enzo Tiezzi are neither a fully unexpected work nor a theory lacking of important potentialities: it is not a strange or eccentric academic exercise. Except the close contact and the dense exchanges with Prigogine, we collocate Enzo Tiezzi in the same context of Gregory Chaitin, of Rachel Carson, of John Harte and Robert H. Socolow, of James Paul Wesley, of Sertorio, of Oort and Peixoto, just to cite the most strictly related. Our Academy had the privilege and the honor of having Enzo Tiezzi in its ranks. We think that merits and developments of the thinking of this scholar have to produce important and lasting fruits in the future.

Abstract Background Parental substance misuse is reported to endanger the health and psychological development of children and adolescents. The aim of the present study was to estimate the number of children currently affected by substance use disorders (SUDs) of any adult living in the same household. Methods Data came from the 2018 German Epidemiological Survey of Substance Abuse (ESA) among 18-64-year-olds (n = 9,267) and from population statistics. DSM-IV diagnostic criteria were used to assess SUD (abuse or dependence) related to tobacco, alcohol, cannabis, cocaine or amphetamine. Based on the number of household members, the number of children below the age 18 years and the information on SUD status of the respondent living in this household, the number of children in households with at least one member with SUD was estimated. Results In 2018, there were 13,597,428 children younger than 18 years living in Germany. Of these, 5.2–7.9% (686,482–696,279) were estimated to live in households where at least one adult had an alcohol-related disorder, 5.0–7.4% (674,065–690,792) in households where at least one adult was tobacco dependent and 0.38–1.05% (93,229–142,141) in households where at least one adult had a disorder related to the use of illicit drugs. The total number of children in close contact with SUD adults was estimated at 7.4–11.2% (1,000,725–1,522,667). Conclusions The large number of children affected by adults with SUD has implications for identification and prevention. Substantial variation in estimates, resulting from differences in methods, definition of exposure and exposure to whom, calls for international standardization in order to make estimates comparable.

The effects of using oxygen to partially or wholly replace fuel air in small-size melting furnaces were studied over a range of application fields. Following definition of the useful parameters, testing was conducted on furnaces for melting glass, ferrous metals (pigiron), nonferrous metals (copper alloys), and ceramic materials. In all cases, oxygen-enrichment was found to provide significant energy savings, as well as notable advantages in terms of both plant output and energy consumption.

ABSTRACT Objective: To investigate the shear bond strength (SBS) of orthodontic metal brackets applied to different types of ceramic surfaces treated with different etching procedures and bonding agents. Materials and Methods: Monolithic CAD/CAM ceramic specimens (N = 120; n = 40 each group) of feldspathic ceramic Vita Mark II, resin nanoceramic Lava Ultimate, and hybrid ceramic Vita Enamic were fabricated (14 × 12 × 3 mm). Ceramic specimens were separated into four subgroups (n = 10) according to type of surface treatment and bonding onto the ceramic surface. Within each group, four subgroups were prepared by phosphoric acid, hydrofluoric acid, Transbond XT primer, and Clearfill Ceramic primer. Mandibular central incisor metal brackets were bonded with light-cure composite. The SBS data were analyzed using three-way analysis of variance (ANOVA) and Tukey HSD tests. Results: The highest SBS was found in the Vita Enamic group, which is a hybrid ceramic, etched with hydrofluoric acid and applied Transbond XT Adhesive primer (7.28 ± 2.49 MPa). The lowest SBS was found in the Lava Ultimate group, which is a resin nano-ceramic etched with hydrofluoric acid and applied Clearfill ceramic primer (2.20 ± 1.21 MPa). Conclusions: CAD/CAM material types and bonding procedures affected bond strength (P < .05), but the etching procedure did not (P > .05). The use of Transbond XT as a primer bonding agent resulted in higher SBS.

Eemian Interglacial

Small mammal remains obtained from the European localities dated to the Eemian (Mikulino) age have been analyzed for the first time at a regional scale based on the present biogeographical regionalization of Europe. The regional faunas dated to the warm interval in the first part of the Late Pleistocene display notable differences in fauna composition, species richness, and diversity indices. The classification of regional faunal assemblages revealed distinctive features of small mammal faunas in Eastern and Western Europe during the Eemian (=Mikulino, =Ipswichian) Interglacial. Faunas of the Iberian Peninsula, Apennine Peninsula, and Sardinia Island appear to deviate from the other regions. In the Eemian Interglacial, the maximum species richness of small mammals (≥40 species) with a relatively high proportion of typical forest species was recorded in Western and Central Europe and in the western part of Eastern Europe. The lowest species richness (5–14 species) was typical of island faunas and of those in the north of Eastern Europe. The data obtained make it possible to reconstruct the distribution of forest biotopes and open habitats (forest-steppe and steppe) in various regions of Europe. Noteworthy is a limited area of forests in the south and in the northeastern part of Europe. In these regions, it seems likely that under conditions of relatively high temperatures characteristic of the Last Interglacial and an insufficient moisture supply there could exist open forest stands or forest-steppe landscapes, as suggested by the presence of species indicative of forest-steppe and steppe north of the forest zone. The results obtained are useful in modeling changes in the mammal faunas as well as environmental changes in entire Europe due to global climatic changes (including the global warming recorded at present).

The need to simplify the construction issues of complex structures leads to definition of SmartNodes project as a research which aims to confine the complexity of structure to a limited area (nodes) in order to decrease processing steps and labor intensity by application of additive manufacturing (AM) techniques. Bi-Directional Evolutionary Structural Optimization (BESO) is used to design efficient and elegant nodal connections of large scale spatial structures and minimise the volume of nodes to be printed and to ultimately replace welded, forged and cast connections by 3D printed connections. The prototypes discussed in this paper demonstrate BESO design process through two generic cases.

The Town

What do people make of places? In the present article, I pursue this question from the perspective of a peculiar polysemy in the definition of places found among the inhabitants of the small Romanian industrial town of Copşa Mică. Copşa Mică suffers conditions so extreme that, analytically speaking, the town can be described as a zone - that is, as a limited area in which the conditions are such that normal limitations do not apply; thus, zone refers to a line that in a way effaces all lines, a boundary that negates all pronounced boundaries. What do we find instead? The local construction of safe ground reaches deeply into various cultural spheres, particularly into a moral order, by which the questions of where to stay and who is where are replaced to a certain extent by who is places - who is entitled to make them count as so different that it makes a difference? As a result, the local surroundings place themselves, so to speak, as contradictions brought to light in polysemous definitions such as: wherever it is safe, it is also exceptionally unsafe.

Territory of Mongolia is situated in the center of Asia, a crossroad of the potential migration routes, that connect different Eurasian macroregions. Here an example of earliest appearance and longterm existence of small blade and microblade production has been found. Beyond that, the industries, that appeared within limited area of the Middle Selenga Basin in the late MIS3 — early MIS2, contained the earliest for Northern and Central Asia geometric and non-geometric microliths. They have been found in the sediments of Kharganyn Gol 5 and Tolbor-4, — 16 and –21. They end up in LGM — post- LGM which cause depopulation in the region and following changes in the human groups, occupying this territory. An understanding of the character, causes and specifics of such early appearance of the microblade and bladelet production, and especially geometric microliths, impose the arrangement and definition of the terminology, associated with microlithic assemblages in Asia. This is due to the fact that in the archaeological definitions of both processes and the desired forms of artifacts associated with the production and use of microliths, there are significant discrepancies that complicate the understanding of the described phenomena. The article provides an overview of the research terminology of microlithization processes, and also determines the position of the microlithic complexes of Mongolia in the Upper Paleolithic system of the eastern part of Asia.

AbstractSocial contact data are increasingly being used to inform models for infectious disease spread with the aim of guiding effective policies on disease prevention and control. In this paper, we undertake a systematic review of the study design, statistical analyses and outcomes of the many social contact surveys that have been published. Our primary focus is to identify the designs that have worked best and the most important determinants and to highlight the most robust findings.Two publicly accessible online databases were systematically searched for articles regarding social contact surveys. PRISMA guidelines were followed as closely as possible. In total, 64 social contact surveys were identified. These surveys were conducted in 24 countries, and more than 80% of the surveys were conducted in high-income countries. Study settings included general population (58%), schools/universities (37%) and health care/conference/research institutes (5%). The majority of studies did not focus on a specific age group (38%), whereas others focused on adults (32%) or children (19%). Retrospective and prospective designs were used mostly (45% and 41% of the surveys, respectively) with 6% using both for comparison purposes. The definition of a contact varied among surveys, e.g. a non-physical contact may require conversation, close proximity or both. Age, time schedule (e.g., weekday/weekend) and household size were identified as relevant determinants for contact pattern across a large number of studies. The surveys present a wide range of study designs. Throughout, we found that the overall contact patterns were remarkably robust for the study details. By considering the most common approach in each aspect of design (e.g., sampling schemes, data collection, definition of contact), we could identify a common practice approach that can be used to facilitate comparison between studies and for benchmarking future studies.
