A design for a plasma-arc steel-melting furnace with four plasma generators and a rational method for steelmaking, which can decrease the heat time and the electric energy consumption, are pro- posed. The rational arrangement of wall plasma generators in the liquid stages of a heat are determined by analytical investigations. 相似文献

The energy and technological conditions of operation of DSP-150 electric furnaces are studied during melting of scrap and prereduced pellets in order to reveal the reserves of decreasing the energy consumed for the production of electric furnace steel. The influence of heating of a metallic charge, the relation between scrap and pellets in a metallic charge, and the bath temperature conditions on the technical-and-economic indices of electric furnaces is revealed. 相似文献

A data acquisition system of the OKA experiment on studying rare kaon decays on the U-70 accelerator is described. The basis of the blocked data acquisition system was the high-speed multichannel information system MISS with autonomous controllers that read out the front-end electronics in the sequential data reading mode and buffering data during the accelerator burst. Data stored in the buffer memory are read out and processed at the end of the accelerator burst. The DATE package builds subevents from event fragments and events from subevents via the event building network. The event building network with the star topology is made with 1GbE-interfaces and 24 × 1 Gb E-switch. The GlusterFS cluster file system underlies the distributed storage system. 相似文献

Recent developments in Origins of Life research have focused on substantiating the narrative of an abiotic emergence of nucleic acids from organic molecules of low molecular weight, a paradigm that typically sidelines the roles of peptides. Nevertheless, the simple synthesis of amino acids, the facile nature of their activation and condensation, their ability to recognize metals and cofactors and their remarkable capacity to self-assemble make peptides (and their analogues) favourable candidates for one of the earliest functional polymers. In this mini-review, we explore the ramifications of this hypothesis. Diverse lines of research in molecular biology, bioinformatics, geochemistry, biophysics and astrobiology provide clues about the progression and early evolution of proteins, and lend credence to the idea that early peptides served many central prebiotic roles before they were encodable by a polynucleotide template, in a putative ‘peptide-polynucleotide stage’. For example, early peptides and mini-proteins could have served as catalysts, compartments and structural hubs. In sum, we shed light on the role of early peptides and small proteins before and during the nucleotide world, in which nascent life fully grasped the potential of primordial proteins, and which has left an imprint on the idiosyncratic properties of extant proteins. 相似文献

The development of manufacturing technology for the ceramic helium-cooled test blanket module (CHC TBM) is performed in the framework of the concept for RF Federal government program to master the fusion nuclear energy and as a part of the development of DEMO blanket technology.The main technical approach to the development of CHC TBM manufacturing technology is to provide the “combined” analogy with design decisions of DEMO blanket structural elements.The manufacturing technology of CHC TBM structural elements (first wall cramp, load-bearing back cramp, tritium-breeding element and attachment system) has been proposed during the period of 2004-2007. The design details of TBM structural elements and critical issues of manufacturing technology development are also presented in this paper. 相似文献
