Abstract This study examines how medical discourse and culture were affected by the denazification policies of the Soviet occupation authorities in East Germany. Examining medical textbooks in particular, it reveals how the production and dissemination of medical knowledge was subject to a complex process of negotiation among authors, publishers, and censorship officials. Drawing on primary-source material produced by censorship authorities that has not been rigorously examined to date, it reveals how knowledge production processes were structured by broader ideological and political imperatives. It thus sheds new light on a unique chapter in the history of censorship.

Although permanent magnet couplings (PMCs) have been under research for many years and have found successful industrial applications, this is still a technology under development. Accurate parameter determination is of significance for performance analysis and critical decisions on PMC design. However, the determination can often lead to an unacceptable increase in computation, especially when finite elements (FE) are used. The study aims to develop an FE model that is used for the structural design of a standard-disc type PMC for optimal torque. For the quick and accurate design, an integration optimal solution of the response surface methodology (RSM) and the Taguchi’s method was proposed. To verify the simulation, a series of experimental investigations were conducted on a self-developed testing platform. Furthermore, for a minimum set of FE analyses (FEA), a quantitative indicator called contribution rate, which can reflect effect level of structure parameters on the torque, was given based on the Taguchi method. Apart from this, the orthogonal matrix was used for the reduction of the FE calculation. Based on the contribution rate, the response surface methodology was adopted for the optimal torque determination with no increase in the PM volume. According to the optimization results, a fitting formula, which considers the contribution rates of the optimization variables, was presented. The results suggest that the FE simulations agree very well with the experiments, and the fitting formula can be used in the PMC design.

Introduction. The paper deals with the issues of the propaganda system in the Soviet Occupation Zone in Germany (SOZ) between 1945 and 1949. Based on de-classified documents from Russian Archives propaganda organization, channels and methods of propaganda units of the Soviet Military Administration in Germany (SMAG) became a subject to study. The authors emphasize on control means towards German mass media and implementing the Soviet propaganda monopoly in East Germany. Methods and materials. The authors consequently analyze the main channels and methods of positive USSR image broadcasting: radio, press, SMAG propaganda unit lectures, people’s education system, activities of society for Soviet cultural studies, acquaintance trips of German delegations to the USSR, presentations of Soviet exhibitions and films. Analysis and Results. The authors come to a conclusion that the Soviet propaganda in East Germany had a low efficiency. It failed to establish a complete monopoly of Soviet propaganda units in East Germany. The SOZ population could access the propaganda from West Germany and West Berlin, which broadcast a radically negative image of the USSR. Besides, the units and institutions of the Group of Soviet Occupation Troops in Germany (GSOTG) created their own image of Soviet people, which was different from the ideal and broadcast one. Thus, it turned out to be impossible to provide the unification of the broadcast and perception of propagandist materials devoted to the USSR and its population. Soviet propaganda in Germany had gone through the transition by the late 1940s: division of Germany in two states appeared to be a reality, and the establishment of socialist society on Stalin’s model took place in East Germany. Ideological revisiting of the Soviet social constitution, and so its supremacy over the bourgeois one was to replace the conventional image of the country of total welfare and happiness.

Vibration Signature

Induction motors (IMs) play an essential role in the field of various industrial applications. Long-time service and tough working situations make IMs become prone to a broken rotor bar (BRB) that is one of the major causes of IMs faults. Hence, the continuous condition monitoring of BRB faults demands a computationally efficient and accurate signal diagnosis technique. The advantage of high reliability and wide applicability in condition monitoring and fault diagnosis based on vibration signature analysis results in an improved cyclic modulation spectrum (CMS), which is one of the cyclic spectral analysis algorithms. CMS is proposed in this paper for the detection and identification of BRB faults in IMs at a steady-state operation based on a vibration signature analysis. The application of CMS is based on the short-time Fourier transform (STFT) and the improved CMS approach is attributed to the optimization of STFT. The optimal window is selected to improve the accuracy for identifying the BRB fault types and severities. The appropriate window length and step size are optimized based on the selected window function to receive a better calculation benefit through simulation and experimental analysis. Compared to other estimators, the improved CMS method provides better fault detectability results by analyzing vertical vibration signatures of a healthy motor, and damaged motors with 1 BRB and 2 BRBs under 0%, 20%, 40%, 60%, and 80% load conditions. Both synthetic and experimental investigations demonstrate the proposed methodology can significantly reduce computational costs and identify the BRB fault types and severities effectively.

This paper presents the results of theoretical and experimental investigations of a new process of rolling rods from scrap rail heads. First, the industrial applications of scrap railway rails and methods of their recycling are discussed, and then the concept of two-stage rolling of rods from heads cut off from scrap rails is proposed. In the first stage of the process, a rail head preform was rolled in a hexagonal pass of a longitudinal rolling mill. Then in the second stage, the hexagonal bar was skew rolled into a rod in a helical roll pass. Theoretical considerations were based on finite element numerical modelling. The rolling process was simulated under 3D deformation using Forge NxT v.1.1 software developed by Transvalor Company. Calculations were carried out to determine the material flow kinematics, strength, and thermal parameters of the process and to identify the phenomena that might constrain its implementation. The numerical results were verified in experimental tests, during which preforms and rods were formed from scrap rail heads. The tests were conducted in longitudinal and skew rolling mills. The results indicate that rods can be effectively formed from scrap rail heads in just two steps. Rods obtained using the proposed method can be used as full-featured, semifinished products for the manufacture of various types of machine parts.

This article focuses as a case study on Victor Klemperer’s diaristic representation of German-Jewish identity and culture after 1945 in the Soviet Occupation Zone and the GDR. The contribution shows how Klemperer’s professional and social situation remained very uncomfortable even in East Germany. For the diarist, the communist code ‘antifascist/fascist’, just like the code ‘German/un-German’ before it, was tantamount to concealing Jewish origin. His post-Holocaust journals provide an immediate insider’s view of Jewish life in Germany after the Holocaust from the perspective of a victim of active persecution. Against this backdrop, the contribution examines how the author’s original German nationalism gradually makes way, caught between contradictory impulses of assimilation and decreed Jewish identity, for a much more complex understanding of his own cultural identity. Klemperer’s diaries highlight a number of tensions that ultimately reflect on the disjunction between living and writing: The divide between a single and changing self lies at the heart of his diaries after 1945, which depict an astute, complex psychogram of the assimilated German-Jewish bourgeoisie that survived the Holocaust and tried to continue living in communist Germany.

The subject of this study is the activity of the Belarusians in the General Government in 1940–1945. Belarusians were the fifth largest ethnic group in the GG. The German occupation authorities, applying the principle of “divide and conquer”, were ready to give Belarusians some freedom in the sphere of culture, religion and economy. In 1940, the Belarusian Committee was established in Warsaw, with branches in Biała Podlaska and Kraków. The majority of committee members were Belarusians and Poles – prisoners of war and refugees from the Soviet occupation zone of Poland. As a priority of this organization, cultural, educational and religious activities among the Belarusians in the General Government were recognized. The activists of the committee managed to create a school in Warsaw and two parishes (Orthodox and Catholic). Belarusian activities faced some difficulties. Serious problems for the Belarusians Committee caused the activities of Ukrainian organizations in the GG. One of the episodes in the history of the Belarusian Committee is the cooperation of its activists with German military intelligence.

When Austrian composer and committed Marxist Hanns Eisler was forced out of the United States in 1948, he returned to Vienna and hoped to settle there. Instead, a commission for Goethe’s bicentennial celebration the following year drew him to East Berlin and the SBZ (Soviet Occupation Zone), soon to be the German Democratic Republic (GDR, or East Germany), and set him on the path to be that country’s most prominent composer. This chapter examines the piece Eisler wrote for that commission, Rhapsodie für großes Orchester (Rhapsody for large orchestra) (1949), which set text from Goethe’s Faust II, as well as his libretto for a proposed opera entitled Johann Faustus. East German reception of these pieces reveals the centrality of Goethe’s Faust for national identity formation in the fledgling GDR.
