The Italian State's Active Support for the Aeronautical Industry: The Case of the Caproni Group, 1910–1951

Based on Italian and foreign archival sources, this study shows how Italy's active assistance to its industrial apparatus soon included the newly born aircraft industry, including the Caproni Group. However, after World War II the Group went bankrupt along with most aircraft manufacturers. The suspension of aircraft development, the preference for importing allied (American and British) aircraft for civil airlines, and the denial of international assistance were the ensuing political and economic costs of defeat. In the end, Italy nationalized what was left of its aviation firms. Also, nationalization was consistent with its industrial history and represented the only way to help this sector survive.

History of the Сreation of Home Built Equipment for the Industrial Cultivation of Microorganisms

A bioreactor (cultivator or fermenter) is one of the main elements of the vast majority of instrumentation-technological lines of immunological medicinal preparations. The construction of special equipment for industrial microbiology in our country was determined by the research, related to the development of technology of the production of live plaque vaccine. In the early 1930’s A.L. Berlin studied the approaches to the creation of laboratory cultivating devices in the city of Saratov on the basis of the State Regional Institute of Microbiology and Epidemiology of the South-East of Russia, the People's Commissariat of Health of the RSFSR. At the same time this problem has been solved by N.G. Shcherbina in the Crimean Sanitary-Bacteriological Institute (Sevastopol). In 1936, a group of researchers from the Scientific Research Institute of Epidemiology and Hygiene of the Red Army (Kirov) was involved in the research of the processes and technologies of the industrial microbiology. In 1946 the first industrial apparatus of A.F. Shesterenko under sterile conditions ensured the production of large volumes (up to 800 mattresses) of the culture of the vaccine strain EV of the NIIEG line of the plague microbe.

Fault Diagnosis of Car Engine by Using a Novel GA-Based Extension Recognition Method

Due to the passenger’s security, the recognized hidden faults in car engines are the most important work for a maintenance engineer, so they can regulate the engines to be safe and improve the reliability of automobile systems. In this paper, we will present a novel fault recognition method based on the genetic algorithm (GA) and the extension theory and also apply this method to the fault recognition of a practical car engine. The proposed recognition method has been tested on the Nissan Cefiro 2.0 engine and has also been compared to other traditional classification methods. Experimental results are of great effect regarding the hidden fault recognition of car engines, and the proposed method can also be applied to other industrial apparatus.
