From May 24 to May 27, 2021 the XVIth International of steelmakers took place in Ekaterinburg, in which 324 specialists took part. The Congress began from the plenary session following by the work in the four sections: “Ore processing, reducing processes, blast furnase and nonblast-furnace ironmaking”, “Technologies of steel production, simulation and process control”, “Casting, crystallization and finishing properties of steel”, “Energy effectiveness, resources saving and ecology”. More than 80 reports were delivered and discussed. Within the congress a competition of young specialists (students and postgraduates) was organized. An innovation of the congress was organization of round tables, where actual items were being discussed. The activity of the participants showed a high actuality of both the subjects and the parties dialog format. The company “VPO Steel” organized a round table “The role of refractories in metallurgy”. Representatives of largest metallurgical companies took part in the discussion. Round table “Perspetives of carbonless metallurgy – a myth ar reality” attracted lively interest of the participants. The participants of the round table heard the reports by subjects related to decrease of carbon footprint and problems of hydrogen energetics development in steel industry. The closing plenary meeting of the XVIth congress of steelmakers was devoted to discussion of the results of sections work and elaboration of some recomendationd, made as a resolution.

The Individual

The Sustainable Complex Triangular Cells (SCTC) and bio-cultural/cultural models of human society are employed here. Regarding SCTC model, the cell areas represent the individual´s carbon footprint. Scalene triangles represent each individual in the present competitive standard (inward arrows). Equilateral triangles (outward arrows) are “summed” so as forming cooperative-hexagonal bodies leading to a collaborative model of society, reducing the total carbon footprint area as regard the formal analogous sum of each individual (inward) non-cooperative triangle. We particularly have focused on environmental global limits of the capitalist system, with SCTC modeling an accelerated global anti-ecological “scalenization” process from the 29 crisis to the present neoliberal stage of capitalism. Employing again the SCTC model, we describe and exemplify instable and short lifetime “islands” built up through evanescent local process of “cooperative equilateralization” (outward arrows) in the last 40 years. Such non-capitalist features were “mixed in” with competitive “scalenized” features of the capitalist “ocean”. In the final topic, we will consider bio-cultural (Nowak and Wilson) models of the human history and a cultural (Weber-Alberoni) model for great inflexions in the western history. All these models intersect via human cooperation. Particularly, that last model is complementary to the above small and instable “islands” sketch: but now we deal with western religious and secular, non- capitalist, purely cooperative experiences, which correspond to the above labeled SCTC “cooperative equilateralization”. Such weber-alberonian “islands” may be – some few times - sufficiently stable for rapid and great expansions leading, e.g., to a “civilizational/environmental jump” in the presently menaced planet.

The following is an edited transcript of a roundtable that took place at the University of Glasgow in September 2018. The roundtable was organized by Dr. Julia McClure in conjunction with the Poverty Research Network’s conference - Beyond Development: The Local Visions of Global Poverty. That conference brought into focus the ways in which the global and local levels meet at the site of poverty and highlighted the different conceptions on the global are generated from the perspective of poverty. The roundtable brought together leading scholars from Europe, Africa, Asia and North and South America to take stock of global history as a field, to consider the role of existing centres of knowledge production, and to assess new directions for the field.

<p>The number of iron sand reserves is mostly spread in the coastal waters of Indonesia, from the coast of Sumatra, the southern of Java to Bali, the beaches of Sulawesi, beaches in East Nusa Tenggara (NTT), and the northern coast of Papua. Total reserves for ore are 173,810,612 tons and metal as much as 25,412,652.62 tons. But its utilization was not optimal because PT. Krakatau Steel, and PT. Krakatau Posco has produced steel plates only 24,000 to 36,000 tons per year. While the need for steel plates for the shipping industry each year requires 900,000 tons per year. With the need for raw material for steel plates in the form of iron sponges with Fe ≥ 60%, PT. Krakatau Steel is still imported from abroad. The proof is PT. Krakatau Steel before and during the year 2000 still imported Iron Ore Pellets from the countries of Sweden, Chille and Brazil for 3,500,000 tons per year. This condition is the cause of the national steel industry unable to compete with the foreign steel industry because imported raw materials are subject to import duties. This is an opportunity to build a steel raw material company because all this time the steel raw material industry in Indonesia has only two companies. This condition encourages the manufacture of iron sponges, with the process of making iron sponges with technology adapted to installed production capacity. This study analysed the manufacture of iron sponges using Cipatujah iron sand, as raw material for the manufacture of iron sponges, with the results obtained in the form of iron sponges with the highest levels of Fe ≥60.44%. This can be used for the purposes of raw materials for steel making PT. Krakatau Steel (PT. KS), because so far PT. KS claims that Fe &lt;60% local sponge iron products. This can encourage the independence of steel raw materials, which impacts on the independence of the defence industry. But the government must also protect and prioritize steel raw materials for national production for national steel production. With the national government steel industry, the consortium of vendors supplying raw material (iron sponge) to maintain the quality and supply of continuous sponge iron.</p><p><strong>Keywords</strong>: iron sand, iron pellet, iron sponge</p>

Higher education as a subject of study of this article in the summer provides for the process of teaching pedagogical disciplines. When conducting seminars in a higher educational institution, the cognitive activity and creativity of students of individual methods of developing physical activity for the purpose of research. Recognition of students and creative activity of children. conversation “brainstorming”, “game activities” “round table” competition of practical works and methods of their discussion is used. It recognizes students on the basis of methods, determining the conditions for the development of culture and creativity. Specific recommendations are given. Student creativity the fact that active learning has a great influence on improvement, also identified. Results in higher educational institution to improve the process of teaching pedagogical disciplines contributes to. This article is recommended for university professors for use in seminars.
