Abstract:In this paper we describe LIED (Liver: Information, Education and Diagnosis), a diagnostic expert system devoted to medical education in the field of hepatology6. LIED combines the facilities of a traditional expert system for clinical diagnosis with several modules designed for educational purposes. The goal of such modules is to train physicians, in particular as regards the improvement of their problem solving ability (at the end of their curricula students in medicine usually lack experience in organizing an efficient and accurate diagnostic process). Training on real and simulated cases has been widely recognized as a proper approach to clinical experience. The architecture of the diagnostic system is introduced, which forms the core of LIED, and which has been derived from our previous experience, and the various educational functions are discussed that were developed on top of the basic architecture.

Diagnostics System

Abstract Presently, as a result of the technical progress, more and more complicated machines are being used in our everyday life. This is even more the case in relation to technology used at sea, where highly specialised services are needed. Sophisticated marine devices require special diagnostic methods that take into account the specific conditions of use of this type of machinery. In this paper we present the diagnostic systems elaborated to support the exploitation of the vessel power. Marine engine is a complex technical object. For the purpose of diagnostics it is convenient to divide the engine into several units - subsystems such as: piston -crank assembly; working medium exchange system, fuel supply system, lubricating system, cooling system, starting up - reversing system; combustion chamber, etc. The organization of the marine engine and auxiliary machinery diagnostic process can usually come down to two stages, general diagnostics and damage location. Most popular in marine engine diagnostics have been the periodic run analyzers, called pressure analyzers, electronic indicators. The diagnostic system of marine engine is able to assess the current engine condition and give forecast concerning its future operation in a complex way with the use of computer technology. Working out operating decision was based on proper preparation of operational parameters which were processed in a computer according to defined algorithms.

“I'd make thee eat the mischief thou hast vented”: Discourse of Law in Ben Jonson's Catiline His Conspiracy

The Way

This essay explores the discourse of law that constitutes the controversial apprehension of Cicero's issuing of the ultimate decree of the Senate (senatus consultum ultimum) in Catiline. The play juxtaposes the struggle of Cicero, whose moral character and legitimacy are at stake in regards to the extra-legal uses of espionage, with the supposedly mischievous Catilinarians who appear to observe legal procedures more carefully throughout their plot. To mitigate this ambivalence, the play defends Cicero's actions by depicting the way in which Cicero establishes the rhetoric of public counsel to convince the citizens of his legitimacy in his unprecedented dealing with Catiline. To understand the contemporaneousness of Catiline, I will explore the way the play integrates the early modern discourses of counsel and the legal maxim of ‘better to suffer an inconvenience than mischief,’ suggesting Jonson's subtle sensibility towards King James's legal reformation which aimed to establish and deploy monarchical authority in the state of emergency (such as the Gunpowder Plot of 1605). The play's climactic trial scene highlights the display of the collected evidence, such as hand-written letters and the testimonies obtained through Cicero's spies, the Allbroges, as proof of Catiline's mischievous character. I argue that the tactical negotiating skills of the virtuous and vicious characters rely heavily on the effective use of rhetoric exemplified by both the political discourse of classical Rome and the legal discourse of Tudor and Jacobean England.

According to forecasts for 2022, the number of self-propelled agricultural machinery that will fail will be about 100 thousand units. This will have a significant impact on the overall productivity in the field of agricultural production and will require additional financial costs for effective resource-saving environmental-oriented utilization of agricultural machinery with the maximum recovery of secondary resources in the processing of its components. (Research purpose) The research purpose is considering the main life cycles of machinery, including agricultural, and determining the possibility of obtaining secondary resources in the recycling of components of machinery and equipment. (Materials and methods) The authors found that the establishment of an industry-wide recycling system would allow the reuse of usable and recovered parts obtained from decommissioned equipment, as well as receive additional funding from the sale of secondary resources. The authors have found that for the functioning of the whole system, it is necessary to work with a large amount of data related to the ongoing recycling processes, as well as constantly monitor changes in the state and properties of materials. They also found that the maximum use of digital technology is the only way to combine all these requirements and make the system work. (Results and discussion) The article reviews the key points of the use of life cycle method for equipment, including agricultural, reviews the state of machine and tractor park of agro-industrial complex, shows the possibility of using resource-saving ecologically oriented branch system of recycling of agricultural machinery, as well as the movement of waste and material flows in the processing components of utilized machines. (Conclusion) The article presents recommendations on the possibility of efficient disposal of equipment, including agricultural, with the maximum recovery of secondary resources from recycled waste.

With the increase in the production of new machines, it was necessary to pay more attention to their repair and maintenance, expand research, create appropriate standards, and constantly update technical documentation. The pre-1953 repair laboratories were not powerful enough to solve the growing problems. In 1953, it was decided to establish The State Union Research Institute for the Repair and Operation of Tractors and Agricultural Machinery. (Research purpose) The research purpose is in describing the history of GOSNITI establishment, analyzing the tasks and results of the Institute's activities over the first decade. (Materials and methods) The article presents the base of the new Institute and its quantitative composition. The article describes the main objectives of the Institute and its activities. (Results and discussion) Work was carried out to create self-moving workshops for filling filters, electric brake stands, stands for testing fuel equipment, equipment for vibration contact surfacing. The calculations of the repair base for the regions were carried out. The article presents the list of works that were widely implemented in the national economy and the list of publications of technical documentation. GOSNITI was awarded the Order of the Red Banner of Labor by the decree of the Presidium of the Supreme Soviet of the USSR on May 25, 1967, for implementing the system and advanced technology for repairing cars. (Conclusions) The staff of the established Institute successfully completed the tasks set in the first decade.

The article reviews four existing technologies for replacing engine oil and a method for determining its suitability for improving economic efficiency. It is established that the oil is replaced according to the need in accordance with the defect indicators. This technology of oil condition is characterized by a more complete use of its resource. The frequency of replacement is determined by the indicators of condition, which is monitored by special sensors built into the engine lubrication system. However, the difficulty of using this technology is due to the lack of high-quality devices for monitoring the state of running engine oil in the engine.
