Sylvio Simon Brandenburgische Technische Universität Cottbus-Senftenberg IKMZ, Universitätsbibliothek Platz der Deutschen Einheit 2 03044 Cottbus ISBN 978-3-940471-28-4 IURS e.V. Institut für Umwelttechnik und Recycling Senftenberg e.V. www.b-tu.de Vorwort Die GUS- und Osteuropatage der Fakultät Maschinenbau, Elektro- und Energiesysteme sind eingebunden in eine gesamte Veranstaltungswoche, deren zentrales Element der Triebwerkstag (10 Jahre UTC) ist. Mit dem Internationalen Tag in Senftenberg bestehend aus internationalem Brückenbauwettbewerb mit Liveschaltung zur SSOU nach Shanghai und den weiteren internationalen Vorträgen sowie dem Ingenieurtag mit Informationen über Forschungsprofessuren, Automatisierungstechnik und Fabrikplanung. Ein Treffen von Absolventen rundet diese Programmwoche ab. Die Fakultät Maschinenbau, Elektro- und Energiesysteme entstand 2016 im Zuge der Neustrukturierung der Fakultäten der BTU CS nach ihrer Neugründung im Jahre 2013. Sie ging aus den Vorgängerfakultäten Maschinenbau, Elektrotechnik und Wirtschaftsingenieurwesen am Campus Cottbus und der Fakultät für Ingenieurwissenschaften am Campus Senftenberg hervor. Hier sind jetzt die Kompetenzen des Maschinenbau und der Elektro- und Energietechnik vereint. Der Austausch mit Wissenschaftler aus anderen Ländern wird als Tradition an beiden Standorten gelebt. Neben dem Empfang von Wissenschaftlern und Studierenden gehört auch der Besuch in den jeweiligen Ländern dazu. Mit der Gründung des internationalen Netzwerkes neseff im Jahr 2015 in Baku entstand ein Netzwerk, das sich mit seinen Schwerpunkten Energieerzeugung und Energieeffizienz mit bedeutenden und zentralen Fragen der modernen Volkswirtschaften auf breitem Gebiet beschäftigt. Es hat seine Heimstatt im IURS e.V., einem An-Institut der BTU CS. Die Tatsache, dass weitere osteuropäische Universitäten dem Netzwerk beitreten werden, stärkt das Netzwerk und seine Akteure. Zwischen den GUS- und Osteuropatagen der Fakultät 3, die erstmalig stattfinden und dem bereits zum 3. Mal stattfindenden Ingenieurtag in Senftenberg, er folgt der Tradition der Wissenschaftstage der Hochschule Lausitz, ist ein vielseitiges Vortrags- und Besuchsprogramm vorbereitet, das jedoch genügend Zeit für Gespräche und Diskussionen bietet. Ich wünsche uns Allen erfolgreichen Tage an der BTU CS. Sylvio Simon, wissenschaftlicher Leiter des Netzwerkes neseff : [email protected] Inhaltsverzeichnis 1.

NUMERICAL INVESTIGATIONS OF THE UNSTEADY FLOW IN MELTED ALLUMINIUM ALLOYS Karel Fraňa 1Technical University of Liberec, Department of Energy Equipment, Liberec, Czech Republic Abstract: Metallurgical processes require a huge amount of the energy needed for heating and transport of the melted materials. In order to control heat losses and temperature levels of the melted metal or alloys, a total heat balance in the furnace should be studied in order to improve operating conditions of furnace equipment. Significant temperature differences exist because of different heating fluxes. The numerical simulation of the heat and mass transfer can be applied in order to obtain the temperature and velocity fields of the melted metals. These results can be used to design operating conditions of the furnace as well. Keywords: numerical simulations, melting processes, temperature fields Introduction The metal or generally fluid is melted and stir in the main chamber of the furnace. During the metallurgical processes the temperature and chemical homogeneity are required [1]. The size of the main furnace chamber and the intensity of the fluid stirring can influence this heat process significantly. For instance, if the size of the chamber is too big or fluid stirring too weak, the flow is mix only in some particular region of the chamber. The rest of the chamber region is not affected and the fluid has a tendency to bee overheated or cooled. Furthermore, the quality of the doping of alloys is given by the effectiveness of the mixing process as well. To find appropriate conditions of furnace services, a numerical simulation of the melted fluid flows has been carried out. Results such as velocity or temperature distributions can predict a combination of operating conditions, under which the non-sufficient mixing process in

We analyze the dynamics underpinning the Russian Bitcoin mining industry. Russia’s Siberian region houses the dominant share of the country’s mining facilities. A significant energy surplus from advanced hydropower infrastructure in the region enables miners to secure extremely competitive electricity rates. A federal law passed in 2020 clearly defines Bitcoin mining as an economic activity but will require entities to operate in a specific manner. Mining hardware that will be used for proprietary mining must be owned in the name of a foreign entity.

Ittekkotc a Alfred Wegener Institute for Polar and Marine Research, Columbusstraße, Postfach 120161, 27515 Bremerhaven, Germany b Institute for Biogeochemistry and Marine Chemistry, University of Hamburg, Bundesstraße 55, 20146 Hamburg, Germany c Centre for Marine Tropical Ecology, Fahrenheitstraße 6, 28359 Bremen, Germany Received 17 June 2003; received in revised form 19 December 2003; accepted 18 March 2004 Abstract The Ob and Yenisei Rivers account for more than one-third of the total fresh water supply to the Arctic Ocean. In the past, their sediment load and particulate organic carbon (POC) discharge into the Kara Sea has been measured at stations in the hinterland far south of the estuaries. Suspended matter has been sampled in the estuaries and southern Kara Sea within the framework of the joint Russian–German ‘‘SIRRO’’ program (Siberian River Run-Off), allowing a reliable new estimate of fluxes from the rivers into the Kara Sea. Our estimates of annual supplies of sediment (3.76 Â 106 t), particulate organic carbon (0.27 Â 106 t) and particulate nitrogen (PN) (0.027 Â 106 t) from the Ob River to the Kara Sea are lower than earlier estimates from the northernmost gauging station in the hinterland due to deposition of particulate matter in the Ob Bay. On the other hand, our estimates of the Yenisei’s annual sediment (5.03 Â 106 t), particulate organic carbon (0.57 Â 106 t) and particulate nitrogen (0.084 Â 106 t) supplies to the Kara Sea are probably too high, as they suggest a pure bypass system in the investigated area.

  • Variability of Conch Morphology in a Cephalopod Species from the Cambrian to Ordovician Transition Strata of Siberia
    Variability of conch morphology in a cephalopod species from the Cambrian to Ordovician transition strata of Siberia JERZY DZIK Dzik, J. 2020. Variability of conch morphology in a cephalopod species from the Cambrian to Ordovician transition strata of Siberia. Acta Palaeontologica Polonica 65 (1): 149–165. A block of stromatolitic limestone found on the Angara River shore near Kodinsk, Siberia, derived from the exposed nearby Ust-kut Formation, has yielded a sample of 146 ellesmeroceratid nautiloid specimens. A minor contribution to the fossil assemblage from bellerophontid and hypseloconid molluscs suggests a restricted abnormal salinity environment. The associated shallow-water low diversity assemblage of the conodonts Laurentoscandodus triangularis and Utahconus(?) eurypterus indicates an age close to the Furongian–Tremadocian boundary. Echinoderm sclerites, trilobite carapaces, and hexactinellid sponge spicules were found in another block from the transitional strata between the Ust-kut and overlying ter- rigenous Iya Formation; these fossils indicate normal marine salinity. The conodont L. triangularis is there associated with Semiacontiodus iowensis and Cordylodus angulatus. This means that the stromatolitic strata with cephalopods are older than the early Tremadocian C. angulatus Zone but not older than the Furongian C. proavus Zone. The sample of nautiloid specimens extracted from the block shows an unimodal variability in respect to all recognizable aspects of their morphol- ogy. The material is probably conspecific with the poorly known Ruthenoceras elongatum from the same strata and region.

Evgenia Vanadzina Lappeenranta 2017 Abstract Lappeenranta University of Technology School of Energy Systems Electrical Engineering Kuznetcova Aleksandra Benefits of smart meters in Russian electricity market Master’s thesis 2017 81 pages, 12 figures, 13 tables and 4 appendices Examiners: Prof. Samuli Honkapuro DSc. Evgenia Vanadzina Keywords: smart meters, benefit, electricity market, cost-benefit analysis. Smart metering technologies have become more popular in Europe. The benefits of smart metering are obvious both for different stakeholders, and for the whole energy system. Cost-benefit analysis of smart metering system was implemented for all European countries. However, there is no similar analysis for Russian electricity market. This work aims to consider specific features of electricity market in Russia and conduct a cost-benefit analysis for residential customers from the guaranteeing supplier point of view. Main costs were defined as capital and operational expenditures and main benefits as a profit from demand response, which led to peak demand reduction and decrease in guaranteeing supplier expenses. Results suggest that smart metering system implementation is not economically justified in Russia. However, it can be implemented optionally or subsidized. 2 Table of content 1.

Als Dissertation angenommen vom Fachbereich Geowissenschaften der UniversitäHamburg aufgrund der Gutachten von Herrn Prof. Dr. K.-C.Emeis und Frau Dr. B. Gaye-Haake. Hamburg, den 20. April 2004 Eine elektronische Version dieses Dokumentes kann bezogen werden unter: http:llwww.awi-bremerhaven.de * Veröffentlichunge Preface One of the important characteristics of the Arctic Ocean, surrounded by the world's largest shelf seas and seasonally to permanently covered by sea ice, is its large river discharge which is equivalent to 10Y0 of the global runoff. The freshwater balance of the Arctic Ocean is an irnportant factor controlling sea-ice extent and intermediatelbottom water formation in the Northern Hemisphere, as weil as Arctic Ocean surface-water conditions. The formation and melting of sea ice result in distinct changes in the surface albedo, the energy balance, the temperature and salinity structure of the upper water masses, and the biological processes, and thus play a major role in the global climate System, Having in mind this importance of river discharge, a bilateral Russian-German multidisciplinary research project to investigate the "Siberian River Run-Off (SIRRO), specifically of the Westsiberian rivers Ob and Yenisei, was established in 1997 (see Stein et al., 2003, and further references therein for details).

  • Discharges and Yields of Suspended Sediment in the Ob' and Yenisey
    Erosion and Sediment Yield: Global and Regional Perspectives (Proceedings of the Exeter Symposium, July 1996). IAHS Publ. no. 236, 1996. 115 Discharges and yields of suspended sediment in the Ob’ and Yenisey Rivers of Siberia NELLY N. BOBROVITSKAYA, CLAUDIA ZUBKOVA State Hydrological Institute, 23 Second Line, 199053 St Petersburg, Russia ROBERT H. MEADE US Geological Survey, MS 413, Box 25046, Denver, Colorado 80225, USA Abstract The northward-flowing rivers of Siberia deliver immense quantities of water but only relatively small quantities of sediment to the Arctic Ocean. The relatively low delivery of sediment to the ocean by these rivers is explained by the large areas of forest and swamp in their basins. In the Ob’ River, sediment yields tend to increase between the headwaters and Kamen’ na Obi. Further downstream, sediment yields gradually decrease. Near the mouth of the Ob’ River, at Salekhard, sedi­ ment yield has remained constant at about 5.3 t km-2 year'1. In the lower Yenisey River, the already small natural sediment yield of 5.41 km'2 year'1 has been decreased several fold by the construction of massive reservoirs on the main stem and on the tributary Angara River, and presently equals 1.8 t km'2 year"1. INTRODUCTION Intensive collection of sediment data in the rivers of the Soviet Union (including Siberia) began during 1935-1938. The stations where sediment discharge is measured presently number about 240 in the Ob’ River basin and about 220 in the Yenisey River basin. The rivers are divisible into three parts: the upper reaches where suspended sediment is mobilized; the middle reaches where sediment is transported, deposited, and re­ mobilized downstream; and the lower reaches where sediment accumulates (Polyakov, 1935; Lopatin, 1939; 1952; Shamov, 1954).

Its banks were subjected to detailed archaeological surveys whose ¿ ndings were integrated into cultural and chronological models. Because most of the Angara has become part of a system of arti¿ cial reservoirs, we are unable to test these models using new planigraphic and stratigraphic information concerning all the riverside archaeological sites. In 2014, we carried out an in-depth archaeological survey of a 115-kilometer stretch of the northern Angara bank between the Boguchany Dam and the village of Boguchany. Survey results were supplemented by archival data. The ancient habitation layer was found to extend over a large area of the Angara terrace. Artifacts have tended to accumulate in weakly strati¿ ed parts of the subaerial complex. Known archaeological sites span the period from the Neolithic to the Late Iron Age.

  • Hydropower: Past and Future
    THE GREAT TRANSITION: Shifting from Fossil Fuels to Solar and Wind Energy Lester R. Brown, with Janet Larsen, J. Matthew Roney, and Emily E. Adams © Earth Policy Institute 2015 8 Hydropower: Past and Future In 1966, at the age of 72, Mao Zedong famously swam in Asia’s longest river, the Yangtze, to demonstrate his vigor and the strength of the Cultural Revolution. A dip in the fast-moving waters a decade earlier had inspired him to write a poem about how a dam on the Yangtze—a project that had been envisioned for flood control as early as 1919 by the founder of the Republic of China, Sun Yat-sen—could change the world. In 1994, some 18 years after Mao’s death, construction began on what would become the largest hydroelectric project ever seen: the Three Gorges Dam. First online in 2003 and fully completed in 2012, the 600-foot-tall Three Gorges Dam has an estimated electricity generating capacity of 22,500 megawatts. Its annual output of some 83 million megawatt-hours is equal to the power from burning 45 million tons of coal or running 12 nuclear reactors. Yet despite its major elec- tricity contribution, the monumental dam—like many of the 300 mega-dams worldwide—has had a profound environmental, social, and economic impact. The problems associated with the Three Gorges Dam Hydropower: Past and Future 115 are highly visible. Its construction flooded 244 square miles and displaced over 1.4 million people. The Chinese government’s promise to provide them with a home and life after relocation comparable to their previous liveli- hoods in economic terms has simply not materialized.
