The description of the state of power engineering in Russia in the pre-revolutionary period, data on the production of electricity per capita are presented. A brief history of the creation of a commission for the development of the State Electrification Plan of Russia (GOELRO plan) and some results of its implementation are provided. The construction of the first large power plant in the South Urals, built according to the GOELRO plan, - Chelyabinsk State District Power Plant, which at that time was of great importance for the development of the region's industry and remains one of the most powerful power plants at the present time, is described. The possibilities of using renewable energy sources, in particular local hydropower resources for energy production, are disclosed. The problems of the Porozhskaya Hydropower Plant - the oldest and unique hydroelectric power plant in the Urals are designated, the characteristics of small hydropower plants in the Southern Urals are given, the prospects for using the hydropower potential of the Chelyabinsk region are revealed. The potential of solar and wind energy is discussed, the characteristics and features of solar power plants in the Urals and wind power plants with a vertical axis of rotation, developed at the South Ural State University, are specified. It is established that biomass as a resource for energy production has good prospects for use, but due to climatic conditions, this direction has not yet been developed. It is shown that small and distributed energy is still an important component in the general energy of the region and the country.

The Impact

The article reviews the collection of documents “Emperor Alexander II and the Southern Urals,” published in 2019 and dedicated to the 200th anniversary of the Emperor. The book tells of the Tsarevich’s journey through the Southern Urals in 1837 and of manufacture of gifts to him by the Zlatoust craftsmen; a separate part consists of documents devoted to the reign of Alexander II and the impact of the Great Reforms on the development of the region. The collection ends with documents on the perpetuation of the Emperor’s memory. The review proves that this collection of documents closes the topic of relations between Alexander II and the Southern Urals, which has been little studied in the historiography. It concludes that the initiators of the publication – employees of the Joint State Archive of the Chelyabinsk Region – have included in the book legislative acts, recordkeeping materials, materials of the periodical press, sources of personal provenance, photographs, and visual materials. There is a list of archives and museums from which the sources originate: state archives of the Chelyabinsk, Orenburg, Sverdlovsk regions, the National Archive of the Republic of Bashkortostan, the Archive of the Zlatoust City District; the Verkhny Ufaley and Zlatoust local history museums; the Russian State Archive of Photo Documents, the State Russian Museum; the Department for Preservation of Historical Heritage of the South Ural Railway, the Russian State Historical Archive, and the State Archive of the Russian Federation. The review describes the structure of the collection and contends that it contributes to comprehensive coverage of the studied problems. It allows its readers to find the needed documents confidently and quickly, even with minimal research skills. Photo documents (little–known photographs and drawings) included in the collection complement the text quite successfully. The reviewers underscore that the publication contains three extensive introductory articles, the reading of which contributes to a deeper understanding of the sources. Thus, the review concludes that the collection has expanded the documentary base adequately in order to spur extensive research of the pre–revolutionary history of the Southern Urals.

Relict Species

The geographical and phytocoenotic areas of the endemic of the Southern Urals Delphinium uralense that is a relic species of the ancient Pleistocene steppe were studied. Species is listed in the Red book of the Russian Federation (2008) and the Red Book of the Republic of Bashkortostan (2011). The main part of the geographical area of the investigated species is limited by the Zilair plateau located in the south-western tip of the Ural Mountains, within the Urals fold-block surface. The phytocoenotic area of this species includes the xerophytic communities referring to 2 classes, 3 orders, 4 alliances, 1 suballiance, 2 associations, 1 subassociation, 1 variantand 4 non-ranking communities The formation of the unique complex of xerophytic oak-larch sparse forests and rocky steppes in the southern Urals is linked with the occurrence of the mountainous steppe with larch groves, which were the remnants of the xerophytic mountain landscape —“Pleistocene floristic complex” (Igoshina, 1961, 1963). The enrichment the floristic composition of the complex took place in the late Pleistocene due to following facts: the appearance of rock and mountain-steppe Asian relict species (Ryabinina, 1993), the migration of Eastern Siberian elements to the West, the movement of European species to the East, the formation of the Urals endemic floristic races (Krasheninnikov, 1939). Later, in the Holocene, the Pleistocene floristic complex was enriched by some species of broad-leaved forests (including oak Quercus robur), the penetration ofthe south richsteppe flora, and replenishment of the floristic complex by the Pontic and Sarmatic species (Igoshina, 1961). As a result of mentioned above processes a unique complex of xerophytic rocky mountain steppes and of sparse oak and larch elfin woodswas formed in the Zilair plateau.

Data Assimilation Technique

In this work, we investigate the ability of a data assimilation technique and space-borne observations to quantify and monitor changes in nitrogen oxides (NOx) emissions over Northwestern Greece for the summers of 2018 and 2019. In this region, four lignite-burning power plants are located. The data assimilation technique, based on the Ensemble Kalman Filter method, is employed to combine space-borne atmospheric observations from the high spatial resolution Sentinel-5 Precursor (S5P) Tropospheric Monitoring Instrument (TROPOMI) and simulations using the LOTOS-EUROS Chemical Transport model. The Copernicus Atmosphere Monitoring Service-Regional European emissions (CAMS-REG, version 4.2) inventory based on the year 2015 is used as the a priori emissions in the simulations. Surface measurements of nitrogen dioxide (NO2) from air quality stations operating in the region are compared with the model surface NO2 output using either the a priori (base run) or the a posteriori (assimilated run) NOx emissions. Relative to the a priori emissions, the assimilation suggests a strong decrease in concentrations for the station located near the largest power plant, by 80% in 2019 and by 67% in 2018. Concerning the estimated annual a posteriori NOx emissions, it was found that, for the pixels hosting the two largest power plants, the assimilated run results in emissions decreased by ~40–50% for 2018 compared to 2015, whereas a larger decrease, of ~70% for both power plants, was found for 2019, after assimilating the space-born observations. For the same power plants, the European Pollutant Release and Transfer Register (E-PRTR) reports decreased emissions in 2018 and 2019 compared to 2015 (−35% and −38% in 2018, −62% and −72% in 2019), in good agreement with the estimated emissions. We further compare the a posteriori emissions to the reported energy production of the power plants during the summer of 2018 and 2019. Mean decreases of about −35% and−63% in NOx emissions are estimated for the two larger power plants in summer of 2018 and 2019, respectively, which are supported by similar decreases in the reported energy production of the power plants (~−30% and −70%, respectively).

Hydroelectric power plants often make use of tunnels to redirect the flow of water to the plant power house. Such tunnels are often flooded and can span considerable distances. Periodical inspections of such tunnels are highly desirable since a tunnel collapse will be catastrophic, disrupting the power plant operation. In many cases, the use of Unmanned Underwater Vehicles (UUVs) equipped with mechanical profiling sonars is a suitable and affordable way to gather data to generate 3D mapping of flooded tunnels. In this paper, we study the resolution of 3D tunnel maps generated by one or more mechanical profiling sonars working in tandem, considering synchronization and occlusion problems. The article derives the analytical equations to estimate the sampling of the underwater tunnels using mechanical profiling sonars (scanning sonars). Experiments in a simulated environment using up to four sensors simultaneously are presented. We also report experimental results obtained by a UUV inside a large power plant tunnel, together with a first map of this environment using a single sonar sensor.

Subject area Operations and human resourcing. Study level/applicability This case study is intended for use in graduate, executive level management and doctoral programs. The case study illustrates a combined IT and HR driven participative management control system in a flexible organization structure. It is intended for a class discussion rather than to illustrate either effective or ineffective handling of an administrative situation. Case overview The case describes the situation of managing unskilled workforces (≥14,000 workers) during the construction phase of the 4 × 250MW power plants both for purposes of turnout as well as due compensation, in the event of an accident. The approved labour forces appointed for 45 × 8 h. Man-days after a rigorous fitness test and approvals of the safety officer are allocated housing and other necessary amenities and a commensurate compensation system. Expected learning outcomes These include: illustrating typical organizational responsibility structure at a construction site of a large power plant; illustrating the planning and administrative control mechanism in implementing strategy at a construction site of a large power plant; offering students the opportunity to understand and view a typical operational (project) structure; allowing students to speculate adaptations in the wake of an ever-changing business and company environment; and providing an opportunity to introduce a power scenario in India, Indian labour laws and radio frequency identification technology and to relate this to the case in context.

The paper deals with the study of broad-leaved plants of the Southern Urals broad-leaved-conifer forests. Stationary studies were conducted on the territory of the South Ural state natural reserve, where 9 forest sites in different types of broad-leaved forests were laid. The research used standard methods while microclimatic observations used digital thermometers-recorders Thermochron. The authors have obtained some data on the structure and composition of the characteristic types of broad-leaved forests with oak and maple domination. The authors have classified ecosystems and plant communities, selected 3 types of biogeocenoses and 4 types of phytocoenoses. Studies have established that selected types of broad-leaved forests are associated to certain elements of relief and high-altitude levels. The obtained materials provide the basis for further monitoring of forests.

Environmental monitoring of specially protected natural reservations in Russia makes it necessary to analyze periodically the parameters of natural reservations to identify the state of components of nature. The Bashkir Nature Reserve is located in the Southern Urals. The availability of materials on forest management in 1956, 1969, 1979, and 2016 is one of the special features of the scientific fund of the Bashkir Nature Reserve. The analysis of these materials showed stable positive dynamics of the development of coniferous and small-leaved deciduous forestry and its current state.

This paper discusses specialized treatment of the wounded in the hospitals of the Southern Urals in the Great Patriotic War (1941-1945). It is proved that the specialized treatment of the wounded undergone significant changes during 1941-1945. The paper defines nature of injuries and damage, treatment time, forming, distribution of hospital beds and a contingent of the wounded and sick Red Army soldiers. The author states that throughout the war the surgical activity in the South Urals hospitals increased. The study deals with the problem of death in base hospitals. The number of Red Army soldiers deaths was undercounted. This study has shown that due to medical workers of the South Urals hospitals specialized treatment of the wounded made a qualitative leap in the development of the stage treatment. At the beginning of the war general surgery and general therapeutic hospitals were created. Then, in order to ensure the most qualified assistance to the wounded, specialized hospitals and offices were deployed. The authors estimated that the application of advanced methods of treatment in the evacuation hospitals of the South Urals helped to heal 72,3% wounded and 90, 6% patients and they returned to military service. These materials can serve as a basis for further research in the Southern Urals health history and, in general, the history of the South Ural Region, as well as the patriotic education of the youth.
