System Analysis and Decision-Making during Synthesis of High-Performance Hybrid Boilers

© Published under licence by IOP Publishing Ltd. The decision-making analysis for synthesis of high-performance hybrid boiler plants is based on current philosophy of system analysis and synthesis of combined heat and power plants. Energetic and exergetic utilization is used as performance criteria

Feasibility Analysis of Combined Boiler Plant Designs

© Published under licence by IOP Publishing Ltd. This paper discusses the method of perfecting energy saving actions in boiler plants based on the analysis and optimization of their performance indicators. A boiler-house plant with low-potential secondary energy resource and external combination units is taken as a study object

Representation of gender concepts in the Russian and polish languages

© Medwell Journals, 2015. The study considers the topical issues of the modern conceptology in particular, the being and representation of gender concepts in a language. The study provides the linguo-culturological analysis of paroemias containing concepts falling within the, general conceptual term 'family' mother-in-law, father-in-law, widower, widow (wdowa-wdowiec) in the Russian and Polish languages. The performed linguo-culturological analysis of conceptual terms relating to the general concept 'family' has proved that there is some dialogue between the two Slavic languages and cultures

Energy saving activity on installation of heat exchangers for utilization of afterheat of smoke fumes of industrial furnaces and steam generating units is offered. Problems of their maintenance and methods of elimination of the given problems are considered

Complexes of podand-containing bis(dithiophosphonate) ligands with cobalt(II), nickel(II) and cadmium(II): Recognition of CH2Cl 2

Reaction of the potassium salts of podand-containing bis(dithiophosphonate) s [PhO(4-C6H4)P(S)(SH)OCH2CH2] 2O (H 2 L) with Co(II), Ni(II) and Cd(II) in aqueous EtOH leads to complexes of formulae M2(L-S,S')2. The structural formulae of the compounds were deduced by physico-chemical and spectroscopic methods. It was established that complex Ni 2 L 2 recognizes CH2Cl2. © 2008 Springer Science+Business Media B.V
