Five new bivalve species (Limopsis obscura, L. indubia, L. lacunosa, L. pretiosa, and L. quadrata) from the Upper Eocene of Ukraine (Dnepropetrovsk, Rybal’sky quarry, Mandrikovka Beds) are described. © 2015, Pleiades Publishing, Ltd. Source

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. Source

Analytical formulas are developed for assessment of the influence of dusty air on the energy consumption in a hammer-type crusher applied to coal batch with a high content of fines. Analytical and experimental approaches are adopted. The ≤3 mm class present in the coal batch supplied for crushing forms a dust–air suspension, which is not crushed by hammer impact but significantly increases the drag on the rotor, with consequent increase in energy consumption. In overcoming the drag of the dust–air suspension, the energy consumption in the crusher may be 40% above the rated value. In that case, the removal of the ≤3 mm class from the feed to the crusher is necessary. © 2015, Allerton Press, Inc. Source
