Philosophical bases of improvement of paradigm development methodologies

The analysis of modern literary sources shows that the paradigms of the main areas of human activity were developed in 2013-18, using only time-based methods. However, in 2019, the development of paradigms of mechanics showed that they depend not on time, but only on space. Therefore, there arose a problem: when, where and how to apply the space-based method and the time-based method. This is a problem of improving the methodology for developing paradigms - global strategies, strategies of the behavior of mankind as a whole in a specific area of activity. The analysis of recent studies and publications indicates that this problem has not even been raised in world literature and research practice. In the coming new era, the depletion of basic natural resources of the planet and the aggravation of the need to develop a new, third generation of paradigms will only urge the importance of solving this problem. Therefore, the aim of the research is to improve the methodology for developing paradigms. For this purpose, the following tasks are solved: the analysis of the level of knowledge about space, time and matter is carried out; the essence and content of space, time and matter is determined; the nature of the relationship between the space- and time-based methods is determined; the nature of the connection of space- and time-based methods with matter is established; a brief description of the results obtained is given. Research methods: review of literary sources; historical and logical method; analog method; 2C70; VEO; Babailov’s method. Results: the matter-based methodology as the only methodology for the development of paradigms is created. Scientific novelty: the composition and sequence of the application of methods for the development of paradigms - space- and time-based methods and the matter-based methodology are streamlined. Practical relevance: the implementation of the matter-based methodology in the practice of developing paradigms will result in improving the methodology of strategic planning in an enterprise, which in turn will increase the efficiency of its management and production

The properties of coke breeze briquettes produced by ram briquetting

The paper reports on the results of briquetting coke breeze with a binder in a closed cylindrical press-die. Liquid glass is used as a binder. Approximating curves for the "compaction ratio vs. compaction pressure" dependences are plotted from experimental data. The mechanical properties of the briquettes are determined, namely, drop damage resistance and breaking stress. The results are presented as approximating dependences in the form of a power function. © 2017 Author(s)

Synthesis and thermal study of dual coordination compound of gadolinium (III) and chromium (III)

The paper presents experimental data of thermal studies of coordination compound based on gadolinium nitrate with the DSCmethod; the study was performed in the temperature range from 298 to 1273 C. The thermal analysis has several advantages over the other methods: experimental set up flexibility, fast data receive, automatic data processing, small substance amount. The process of thermal decomposition of the received compound was carried out in both inert and oxidizing environments. During the experiment the temperature was defined, above which heating causes decomposition of the investigated substance and weight loss of the sample

Evolution of surface defects in platinum alloy wire under drawing

The shape and chemical composition of particles polluting the surface of ultrafine wire made of the platinum Pt92.5Pd4Rh3.5 alloy has been revealed by electron microscopy and microspectral analysis. The phenomenon of the appearance of pores in the particles, which are elongated in the direction of drawing, has been discovered. The problem of calculating the stress-strain state is stated by the finite element method. After solving the problem, it is demonstrated that the appearance of additional defects is related to the proportion of stresses in the scheme of metal forming by drawing. © 2017 Author(s).The work was done within the State Task, theme No. 01201375904, and financially supported by the RF Government, No. 211 (contract No. 02.A03.21.0006)

Industrial recycling of technogenic wastes and mineral ore processing

Drop damage resistance is experimentally found and breaking stress is determined in radial compression tests for green and dry chrome concentrate briquettes. The paper studies the influence of compaction pressure and the amount of the binder on compactibility in the testing of cylindrical briquettes. The aim of the study is to determine optimal briquetting process conditions for the production of high-quality metallurgical briquettes by roll briquetting. © 2016 Author(s)

Prospects of paramagnetic lanthanide complexes for magnetic resonance imaging, local thermosensing and diagnosing

The features of the paramagnetic properties of lanthanide (Ln) containing complexes with crown ethers, pivaloyltrifluoracetonato, and EDTA have been studied by 1H and 19F NMR techniques. These complexes are of interest due to the prospect of using some of them as sensors for biology and medicine. The temperature dependencies of the lanthanide-induced shifts revealed that Ln complexes might have practical importance for 1H and 19F NMR temperature control in solutions. It was shown in vitro (using NMR spectrometers and MRI scanners) that these complexes can serve as special NMR thermo-sensitive contrast reagents

Briquette compacting in container with a small taper angle

The aim of the study is to determine the strain state of a briquette during the compacting process. Modeling is performed with the use of a software system for the compaction process. Gurson's yield condition for a plastically compressible continuum is applied. A comparison of the known experimental data is made, and it shows good qualitative convergence results. © 2018 Author(s)
