Today, modern Geotechnical Engineers, who in the past would have considered the phenomena occurring in the (primarily soil) environment, are faced with developments in environmental sciences that are becoming more and more detailed and sophisticated, with the natural phenomena and processes surrounding the civil engineering infrastructure being modelled, designed, monitored, and assessed in a more holistic way [...]

The article is devoted to the reality of the modern historical city in the totality of the actual values of the valuable heritage, traces of the past, mental codes, archetypal images and the memory of civilization. The place of history in today’s socio-cultural fi eld and in the professional context is not clearly defi ned. Together with the understanding of the need to preserve the heritage, traces and memory of the past, there are global trends that mediate the features of the glocal in architecture. However, even this compromise cannot fully demonstrate the complexity of the historical city viability. According to the author, it is necessary to search for reasons that sometimes appear outside the material reality, but address directly to the spiritual world and mental space of a person, which is the main purpose of the article. The emphasis is placed on the artistic dimension of environmental realities, which allows us to determine the living connections of history and modernity on the basis of the author’s concept of artc integration. The article is illustrated by some results of cooperation between the Nizhny Novgorod State University of Architecture and Civil Engineering and the Polytechnic University of Milan (Politecnico di Milano) in the fi eld of reconstruction and renovation of historically valuable territories and author’s photographs.

Anthropocene nostalgia for the 1980s in Netflix’s Stranger Things

Distinctive Type

Expressions of nostalgia for the 1980s in contemporary American culture are diverse. The most interesting of them go beyond a wistful longing for the past. A complex ‘nostalgia trip’ offered by Netflix’s Stranger Things serves as a notable case study of a distinctive type of this sentiment. Instead of yearning for the restoration of previous times, it plays with past aesthetics in a critically articulate manner, effectively demythologizing the depicted decade. I argue that this significant alteration of the traditional sentiment stems largely from the recent acknowledgment of the Anthropocene and its irreversibility. This article aims to examine the peculiar, self-aware, paradoxical nostalgia, which is coloured by the current, Anthropocene-induced fears for the environment and, thus, our future. The analysis of Stranger Things – its thematics, genre, visuals and the meticulously reconstructed image of the presented era – draws parallels to the techniques employed by the ‘novel nostalgia’: bitter, ironic depiction of the past and references to natural phenomena. The study thus investigates the show at the intersection of contemporary nostalgia for the 1980s and the cultural repercussions of the Anthropocene. In so doing, it will unravel the innovation in the programme’s discourse on the 1980s decade in American culture.

The article presents information about of the work of the International Scientific School on Paleopedology for Young Researchers. This school was conducted for ten years in Siberia in the Altai region, where unique Pleistocene loess-soil series are common and paleosoil horizons and modern soils are present simultaneously in one and the same soil profile. For ten years leading Russian and foreign scientists gave lectures both on fundamental theoretical and applied issues of paleopedology, as well as on a number of topical issues of related sciences, conducted master classes on the basic methods of field study of paleosols, and young researchers discussed their ideas and results. The article lists the main themes of the lectures/ naming Russian and foreign scientists who read them. It also informs about the monograph “Paleosols, the natural environment and methods for their diagnosis”, based on selected lectures at the School from its start until 2014 and published in Russian. Other selected lectures were published in two languages (Russian and English) in the series “Paleosols – a source of information about the Past environment”. The aricle draws attention to the key site "Volodarka" as being of great importance not only for conducting field master classes, but also as a convenient training ground for scientific research, since there occur various soil environment that can serve as models created by nature itself.

Mineral Additives

Many studies have been carried out on the problems of civil engineering with the change of human problems today and in the past. These studies contributed to the development of concrete technology. Concrete is an important building material consisting of mixing aggregate, cement and water with or without chemical and mineral additives since the first day of use. Concrete technology has made great progress and continues. With developing concrete technology, self-cleaning concretes have emerged. Many studies have been conducted on self-cleaning concretes by researchers. This article reviews the research published on self-cleaning concretes and presents its role in reducing environmental pollution and its place in future engineering studies. When we look at the studies on self-cleaning concretes that emerged as a result of the developments in concrete technology, it is seen that the developments have progressed considerably. Contemporary civil engineering has provided a highly effective solution for the solution of modern problems. Environmentally friendly building materials will fulfil their duty in reducing air pollution, one of the biggest problems of our time. Self-cleaning buildings and roads that reduce pollution may sound like futuristic ideas, but it is not far away to encounter these structures more widely in our country and our world.

The division of labor amongst a heterogeneous swarm of robots increases the range and sophistication of the tasks the swarm can accomplish. To efficiently execute a task the swarm of robots must have some starting organization. Over the past decade segregation of robotic swarms has grown as a field of research drawing inspiration from natural phenomena such as cellular segregation. A variety of different approaches have been undertaken to devise control methods to organize a heterogeneous swarm of robots. In this work, we present a convex optimization approach to segregate a heterogeneous swarm into a set of homogeneous collectives. We present theoretical results that show our approach is guaranteed to achieve complete segregation and validate our strategy in simulation and experiments.

Data Collection And Analysis

Culturomics was recently introduced as the application of high-throughput data collection and analysis to the study of human culture. Here, we make use of these data by investigating fluctuations in yearly usage frequencies of specific words that describe social and natural phenomena, as derived from books that were published over the course of the past two centuries. We show that the determination of the Hurst parameter by means of fractal analysis provides fundamental insights into the nature of long-range correlations contained in the culturomic trajectories, and by doing so offers new interpretations as to what might be the main driving forces behind the examined phenomena. Quite remarkably, we find that social and natural phenomena are governed by fundamentally different processes. While natural phenomena have properties that are typical for processes with persistent long-range correlations, social phenomena are better described as non-stationary, on–off intermittent or Lévy walk processes.
