Creative people are driven by certain inner forces, inner needs that are part cognitive, part affective. One such force is intellectual curiosity: the need to know or understand. Another compelling drive is dissatisfaction with the status quo. We saw this as the force that impelled Nicklaus Wirth into creating Pascal (Chapter 1, Section 1.7). But few in the emerging computer science community of the first age of computer science epitomized this characteristic more fiercely than Edsger W. Dijkstra. In his case his discontent was with the direction programming had taken in the 1960s. And the strength of his dissat­isfaction was never more evident than in a letter to the editor of the Communications of the ACM in 1968. The practice of communicating new scientific results by their discoverers in the form of compact letters to the editors of scientific journals was, of course, well established in the natural sciences. The British journal Nature (London) had established this tradition right from its inaugural issue in 1869. But in an upstart discipline, as computer science still was, this practice as a means of scientific communication was quite un­usual. (In one of his celebrated handwritten “EWD notes,” Dijkstra, reflecting retrospectively, explained that his short paper was published as a letter to bypass the usual publication pipeline and that the editor who made this decision was Nicklaus Wirth.) Dijkstra had long been concerned with the question of program quality and how one may acquire confidence in the reliability or correctness of a program. But, as the title of the letter— “Goto Statement Considered Harmful”— tells us, the object of his discontent lay in the use of the goto statement— the unconditional branch available in one notation or another in most programming languages, including Algol-like ones. Dijkstra claimed that the quality of the programmers decreased as a function of the frequency of the goto statements in their programs. And so he proposed that the goto should be banished from all high- level programming languages.

The Second High-Level United Nations (UN) Conference on South-South Cooperation (also known as BAPA+40), held in Buenos Aires, Argentina, from 20 to 22 March 2019, promised to reinvigorate efforts to further achieve and implement South-South cooperation (SSC). Forty years on, the Global South is shaping its image as a solutions provider. Immense strides have been made in improving access to allow a multitude of state and non-state actors to cooperate, while broadening and deepening modes of cooperation and facilitating the exchange of knowledge and transfer of technology, thus moving beyond the simplistic view that developing countries require aid to function and move forward. However, noting these symbolic strides, the Global South should move forward by building understanding of monitoring and evaluation (M&E) frameworks; integrating multi-stakeholder models; improving the visibility of peace and security in South-South programming; and building effective communications systems.

A multidimensional analysis of the state of Russian studies on the education issues over 1993–2016 was carried out based on the materials of the data contained in the Web of Science (SSCI, A & HCI and SCI-E databases). There were determined the dynamics and trends of a number of relevant indicators, such as the number of Russian publications by year, the share of these publications in the global flow of publications on education issues, the dynamics of the share of publications made in co-authorship with foreign colleagues, etc. A number of distributions of Russian publications on educational issues was compiled and analyzed: by journals, by Russian regions and cities, by organizations and authors of the publications. It was found that most of these distributions were characterized by a high level of non-uniformity. A list of journals (125 titles) in which Russian works on education issues had been published was compiled. Russian organizations (308) and domestic researchers (about two thousand) engaged in studying the issues of education were identified. It was discovered that more than 200 organizations and about 400 academicians from 60 foreign countries had participated in Russian studies on the education issues.

The paper is limited to the application of hydraulic power to lathes designed for shell making although, in the author's opinion, there is an immense field for the application of the same principles in other directions. Self-contained hydraulic machine tools have been dealt with by Mr. H. C. Town,† but in the system to be described all the machines are operated from a central hydraulic plant. Three complete installations on this principle have been established by the author, and the present paper contains an account of this work from the first experiments in 1915 until about four years ago. The first plant was constructed in 1915 for the production of 3·29-inch shells, known as “18-pounders”, from the solid bar. The output was 2,000 shells per week of 135 hours, with girl operators working on three shifts. The second plant was put down in 1916–17 for an output of 500 9·2-inch howitzer shells per week of 135 hours, also with girls working on three shifts. The third plant is of recent design. It was started in 1938 for the production of 3·45-inch shells, known as “25-pounders”; and was laid out for an output of 1,000 shells per week of 47 hours. This plant included four types of hydraulic lathes which the author was engaged to design for the War Office. Soon after the commencement of the last war in 1914 it became evident that shell production would have to be greatly increased, and engineering firms were pressed to take up shell manufacture. The author, on behalf of his firm, undertook to help in the movement, and he at once set about the construction of some simple machines for the job. These conformed on general lines to the practice of the period as regards design and operation. He soon realized, however, that drastic changes would have to be made if production was to reach the high level that circumstances demanded. Although quite familiar with hydraulic machinery of various types and of many applications in presses and certain types of heavy tools, he was not aware of any instance in which hydraulic power had been applied to the movements of a lathe. It appeared to him, nevertheless, that it would be possible to construct a very useful machine on these lines, and he accordingly started immediately to carry out experiments and to prepare designs. It was considered essential that machines for the duty which the author had in mind should be much heavier and more rigid than the ordinary machines of the time, so that they should be free from vibration and “chatter” or spring with the heaviest possible cutting. The standard of rigidity aimed at was that which would permit a half-crown coin to remain balanced on edge on the moving saddle or turret while the tools were making the heaviest cuts. This object was achieved, and the demonstration was frequently made in the presence of those who came to see the lathes at work.

The article represents trends and results of world investigations for safety of textile materials for humans and environment. The algorithm for identification of potential influence vector of chemical emissions from textile and the environmentally aimed methods based on the alternative chemical substances for textile wet processing were presented. Using the procedure for oleophobic effect determination, the oil resistance levels of a number of modern fabrics for clothes were established. The experimental research results of the oil products concentration in the textile materials after chemical treatment based on the method of the capillary gas chromatography were presented. It was found out that hydrocarbons from C14H30 Tetradecane to С36Н74 Hexatriacontane are the main components with high level of contaminants concentration. The average values of hydrocarbon concentration on the cleaned up samples for the main areas of the clothe surface were determined. Accumulation of residual contaminations, based on saturated hydrocarbons (С17Н36 – С25Н52 block) and related special-purpose clothes areas, was identified. Recommendations for target-oriented correlation of the clothes protective properties were proposed. UWO (unified work order). The research was made in Don State Technical University within the framework of State Assignment of the Ministry of education and science of Russia under the project 11.9194.2017/BCh.

G is reduced torsion-free A belian group such that for every direct sum ⊕G of copies of G, Ext(⊕G, ⊕G) = 0 if and only if G is a free module over a rank 1 ring. For every direct product ΠG of copies of G, Ext(ΠG,ΠG) = 0 if and only if G is cotorsion.This paper began as a Research Report of the Department of Mathematics of the University of Western Australia in 1988, and circulated among members of the Abelian group community. However, it was never submitted for publication. The results have been cited, widely, and since copies of the original research report are no longer available, the paper is presented here in its original form in Sections 1 to 5. In Section 6, I survey the progress that has been made in the topic since 1988.
