The development of humanity is impossible without means of signaling. Signaling in any sphere of human activity has always been a means of ensuring the safety of his life. One of these areas was railway transport, the development of which and, accordingly, signalling facilities began in the early 19th century.With the progress of technological progress in Russia, signaling tools have also evolved, which have gone from the simplest sound and optical signals to modern ones using satellite technologies. Naturally, this path in the technical evolution of mankind is of interest to scientists and just curious people, since knowledge of the stages of the origin and development of signaling allows contemporaries to improve it and at the same time not forget the basics of this area.As a result of this process, the signaling system on railway transport, its means have undergone serious changes. Primitive ways of giving commands - optical (disk, flag) and sound (whistle) to the participants of the movement were pushed by more modern means of signaling, which already involve microprocessor technology and satellite technologies.An example of modern signaling means is the automatic locomotive signaling of a single row of continuous type (ALS-EN). The signal of this type of signaling is more informative: it contains information about the number of free block sections ahead of the train, as well as about the permissible speed of its movement.

The history of animal-borne instrumentation is reviewed from the first basic depth gauge invented in the late 1800s, to the complex animal-borne imagery and archival systems of the present day. A major breakthrough occurred in 1964 when the first time-depth recorder was deployed on a Weddell Seal in McMurdo Sound, Antarctica. The next phase in the study of animals at sea was the use of microprocessors as archival recorders in the mid-1980s. These also were first attached to Weddell seals in McMurdo Sound. Microprocessor technology made possible the next major step of attaching a video camera housed in a submersible case (Crittercam) to a loggerhead turtle. Since the 1990s the field of “Biologging” has flourished, with new additions of satellite and GPS tracking, and resulted in three major international symposiums in the past four years (2003-2007).

James C. Knox’s 1977 paper “Human Impacts on Wisconsin Stream Channels,” published in the Annals of the Association of American Geographers, was a key component of a suite of three papers by him defining the response of rivers to the introduction and management of agriculture and to climate change. In this paper he used the Driftless Area of southwest Wisconsin as a laboratory where he could define fluvial responses by their sedimentary signatures in floodplain deposits. Land-use records dating back to the early 19th century along with shorter climate records provided his understanding of the drivers of change. He found that floods increased as an outcome of land-cover change. Upstream tributaries became wider and shallower as coarse deposits limited their adjustments, while main stem channels became narrower and deeper. His paper reflected the influence of his graduate advisor and especially of prominent faculty colleagues at the University of Wisconsin from fields ranging from soils and climatology to geomorphology and history. The paper was the subject of considerable debate in the professional community, but it remains a much-cited example of Knox’s work in unraveling the Quaternary and Holocene history of rivers of the Driftless Area and by extension the upper Mississippi River system.

ABSTRACTDeception Island in the South Shetland Islands was the site of some of the earliest commercial activity to be carried out in the Antarctic with the early 19th century hunting of Antarctic fur seals. Nearly a century later it was the site of the most extensive anchorage for the reconstructed ships and ocean liners used as non-pelagic whale processing factories. Deception was also the site of what is the only successful land based commercial activity in Antarctic history. The Hektor whaling station operated in Whalers Bay from 1912 until 1931. Most of the remains of the station have now been obliterated by the volcanic activity that occurred in the late 1960s and 1970. By the later part of the twentieth century Deception Island had become a regular stop for the growing Antarctic tourist cruise industry. No other place in Antarctica has been so thoroughly identified with commercial activity.

Literature on the history of ‘paranoia’ (as a clinical concept) is large and confusing. This is partly explained by the fact that over the centuries the word ‘paranoia’ has been made to participate in several convergences (clinical constructs), and hence it has named different forms of behaviour and been linked to different explanatory concepts. The Classic Text that follows provides information on the internal clinical evolution of the last convergence in which ‘paranoia’ was made to participate. August Wimmer maps the historical changes of ‘ Verrücktheit’ as it happened within the main European psychiatric traditions since the early 19th century. After World War II, that clinical profile was to become reified and renamed as ‘delusional disorder’.

Japan has a long history of systematically organizing and carrying out joint research projects between industrial, government and academic institutions. Even competing industries have cooperated in these research projects, and such cooperation has greatly helped Japan's economic progress. The country's technological progress has equalled in some areas and surpassed in others that of countries in the West, and, with the continued advancement of big business, Japan has arrived at a stage at which it can continue its technological progress on its own. This is causing great changes in the meaning and impact of cooperative research endeavours. In this paper the author discusses the problems and possible solutions involved in developing the current cooperative research systems into efficient systems which meet the needs of this new generation of research. He also outlines the potential influence of these changes on the procedures and policies in the current research system, and on user interaction and the results achieved. The paper also constructs a model of a cooperative research system which can meet the country's current requirements.

The paper is devoted to the analysis of the history of the creation of the laser as one of the greatest technical inventions of the 20th century. This paper focuses on establishing a relation between the periodization of the stages of creation and implementation of certain types of lasers, with their influence on the invention of certain types of equipment and industrial technologies for processing the materials, the development of certain branches of the economy, and scientific-technological progress as a whole. In preparing the paper, the generally accepted methods, which are widely used in the preparation of historical research works, have been applied: the historical method – for the study and interpretation of the texts of primary sources and the search for other evidence used for research, as well as for the presentation of historical events associated with the development of laser technology; the historical-genetic method – for studying the genesis of specific historical phenomena and analyzing the causality of changes in the development of laser technology; the historical-critical method – for displaying cause-and-effect relationships, reconstructing events that influenced the development of laser technology; the method of historical periodization. The variety of different possible options for the use of lasers did not allow placing all the collected materials within the framework of one paper, and therefore, the authors have decided to dwell on the facts, which, in the opinion of the paper’s authors, are the most interesting, significant, poorly studied, and little known. The paper discusses the stages of: invention of the first laser; creation of the first commercial lasers; development of the first applications of lasers in industrial technologies for processing the materials. Special attention is paid to the “patent wars” that accompanied different stages of the creation of lasers. A comparative analysis of the market development for laser technology from the stage of creation to the present has been carried out. It has been shown that the modern market for laser technology continues to develop actively, as evidenced by the continued stable growth of laser sales over the past 10 years. This indicates that the demand for laser technology is inextricably linked with the development of high technology production and scientific-technological progress. The analysis has shown that recently, the trends in the use of laser technology have changed; in particular, their industrial and medical applications are decreasing, while there is an increase in their use in the fields of sensor production and communication.

Romantic wanderings of Poles across Saxon SwitzerlandThe history of Polish tourism in the Elbe Sandstone Mountains as well as the literary and artistic reception of the landscape and culture of Saxon Switzerland have never been discussed in detail. The present article is a research reconnaissance. The beginnings and development of tourism in the region came in the late 18th and early 19th century. The 1800s were marked by the emergence of the first German-language descriptions of Saxon Switzerland, which served as guidebooks at the time. From the very beginning Poles, too, participated in the tourist movement in the area. The author of the article seeks to follow the increasing interest in Saxon Switzerland and the appearance of the first descriptions of the region in Polish literature and culture. She provides a detailed analysis of Polish-language accounts of micro-trips to the Elbe Sandstone Mountains by Andrzej Edward Koźmian, Stanisław Deszert, Antoni Edward Odyniec, Klementyna Hoffman née Tańska and a poem by Maciej Bogusz Stęczyński. As the analysis demonstrates, in the first half of the 19th century Poles liked to visit these relatively low mountains in Central Europe and tourism in the region is clearly part of the history of Polish mountain tourism. Thanks to unique aesthetic and natural values of the mountains, full of varied rocky formations, reception of their landscape had an impact of the development of the aesthetic sensibility of Polish Romantics. Direct contact with nature and the landscape of Saxon Switzerland also served an important role in the shaping of spatial imagination of Polish tourists, encouraging them to explore other mountains in Europe and the world, including the Alps. On the other hand thanks to the development of tourist infrastructure in Saxon Switzerland, facilitating trips in the region and making the most attractive spots available to inexperienced tourists, micro-trips to the Elbe Sandstone Mountains marked an important stage in the development of mountain tourism on a popular-recreational level. Polish-language accounts of trips to Saxon Switzerland from the first half of the 20th century are a noteworthy manifestation of the beginnings of Polish travel literature.
