Specialized Subject

In this paper the problems of introducing the teaching of a specialized subject into undergraduate courses are discussed with particular reference to the specific features of machine-tool technology. These cover the facts that the machine must be considered as part of an overall manufacturing system, so that the concept of performance differs from that encountered in other types of machinery such as internal-combustion engines, and that technological, economic, and human aspects must also be considered. Comparisons are made between Continental, particularly German, practice and present practice in some British universities. Some typical approaches to the organization of postgraduate full-time courses and short-term specialized courses are given. Finally, a comparison is made between the employment of university trained engineers in the machine-tool manufacturing and using industries in Great Britain and in Germany.

Positive Effects

Over the decades, more attention has been paid to emissions from the means of transport and the use of different fuels and combustion fuels for the operation of internal combustion engines than on fuel consumption. This, in turn, enables research into products that are said to reduce fuel consumption. The report summarizes four studies of fuel-related innovation products. The studies covered by this report are conducted with diesel fuel and usually contain diesel fuel and three additives for it. Manufacturers of additives are based on already existing studies showing a 10-30% reduction in fuel consumption. Comparative experimental studies related to the use of commercially available diesel fuel with and without the use of additives have been performed in laboratory conditions. The studies were carried out on a stationary diesel engine СМД-17КН equipped with brake КИ1368В. Repeated results were recorded, but they did not confirm the significant positive effect of additives on specific fuel consumption. In some cases, the factors affecting errors in this type of research on the effectiveness of fuel additives for commercial purposes are considered. The reasons for the positive effects of such use of additives in certain engine operating modes are also clarified.

The modern development of society determines the forms and content of the process of teaching foreign languages. The quantity and quality of information in the field of mastering a foreign language is constantly growing as a means of sociocultural, linguistic and cultural and professional development of an individual. A foreign language is currently considered as an integral part of intercultural communication in various fields of objective reality and the development of a culture of interethnic communication. In the process of teaching a foreign language, technologies are becoming increasingly important which makes it possible to achieve the required level of communicative competence in speaking and writing in a shorter time frame and to recreate a virtual spatial temporal communication environment with native speakers. In this regard, the form of distance learning can be more and more prospective, being psychologically more comfortable for students and teachers; many of its elements can be integrated into other forms of training. The article exposes certain information technologies, the use of which increases the effectiveness of teaching a foreign language in distance, part-time and full-time courses. On the example of specific interactive multimedia Internet resources in the field of learning the German language, the urgent importance of using computerized teaching methods for acquiring and enhancing pronunciation, lexical and grammatical skills and knowledge with the aim of forming linguistic and cultural and professional competence of students is emphasized. At the same time, the article highlights importance of non-verbal forms of communication for achieving the desired effect of verbal communication, while relying on relevant audiovisual Internet resources.

Ignition And Combustion

Plasma-assisted ignition and combustion, widely applied in gas turbines, scramjets, and internal combustion engines, has been considered as a promising technique in shortening ignition delay time, improving combustion energy efficiency, and reducing emission. Nonequilibrium plasma can excite the gas molecules to higher energy states, directly dissociate or ionize the molecules and, thereby, has the potential to produce reactive species at residence time and location in a combustible mixture and then to efficiently accelerate the overall pyrolysis, oxidation, and ignition. Previous studies have demonstrated the effectiveness of plasma-assisted combustion by using direct current, alternating currant, microwave, radio frequency, and pulsed nanosecond discharge (NSD). Due to the complicated interaction between plasma and combustion in different types of plasma, detailed plasma-combustion chemistry is still not well understood.
