Paleontological Journal | Year: 2017

Two new species of the genus Crassatella, C. imitatoris sp. nov. and C. pseudolamellosa sp. nov., from Upper Eocene detrital sands of the Rybal’sky quarry of Dnepropetrovsk are described. The species Crassatella oblongula Klushnikov, 1958 is redescribed as a variety. © 2017, Pleiades Publishing, Ltd.

Paleontological Journal | Year: 2015

All presently known bivalve species of the orders Nuculida and Arcida with the taxodont hinge from the Upper Eocene of Dnepropetrovsk (Ukraine) are described and figured. The material includes private bivalve collection of the author collected from 1989 to 2013 and specimens collected by N.A. Sokolov, M.N. Klushnikov, S.V. Popov, O.V. Amitrov, I.A. Goncharova, L.S. Belokrys, V.V. Ablets, V.L. Stefansky, V.V. Dovben’, and V.V. Dem’yanov, housed in the museums, scientific institutes, and private collections. The material comes from three localities: Rybal’sky quarry, village of Mandrikovka, and channel of the Dnieper River under the Amurskii railroad bridge. Revision is based on representative materials from the Rybal’sky quarry and specimens collected by N.A. Sokolov and M.N. Klushnikov. Previously published identification of species from the last two localities are revised. Photographs arranged in 33 plates display 56 species of the genera Arca, Barbatia, Asperarca, Acar, Venignia, Cucullaria, Siptionella, Arcopsis, Trigonodesma, Limopsis, Nucunella, Nucinella, Glycymeris, Nucula, Nuculana, and Yoldia. Of them 32 species are new. Two new genera, Venignia and Siptionella, are established. An extensive collection of shells from the Middle and Upper Eocene of Western Europe kindly placed at my disposal by the Netherlands paleontologist R. Hessel was of great importance for revision. © 2015, Pleiades Publishing, Ltd.

The coke consumption in blast furnaces is determined by the demand for high-temperature heat and its effective utilization. The demand for the reducing agent affects the process through the change in thermal demand. © 2015, Allerton Press, Inc.

The Darcy-Weisbach equation is widely used as model of gas motion in the blast furnace, but it was derived for very different conditions. Its use in describing the gas dynamics of blast furnaces distorts the actual gas motion. Much more precise and useful results are obtained on the basis of the molecular-kinetic theory of gases-specifically, by means of the Clapeyron equation of state of an ideal gas. © 2013 Allerton Press, Inc.

In the analysis of fuel consumption in blast furnaces, attention focuses here on the possibility of minimizing the carbon consumption by lowering the demand for carbon as a reducing agent and also lowering the demand for heat in smelting. With improvement (or deterioration) in the smelting conditions, synchronization of the carbon consumption in heating and reduction entails changing the degree of direct reduction of the iron. The decrease in the consumption of gasified carbon is always less than the decrease in the demand for carbon in any of these processes. © 2013 Allerton Press, Inc.

Coke and Chemistry | Year: 2012

A method of determining the coefficient Kopt(Vt) is proposed. By that means, the optimality of the batch composition may be assessed on an ongoing basis and the mechanical strength of the coke may be predicted. © 2012 Allerton Press, Inc.
