Eight new species of the genus Doliops Waterhouse, 1841 (Coleoptera: Cerambycidae) are described and illustrated: D. anichtchenkoi sp. n., D. gutowskii sp. n., D. savenkovi sp. n., D. shavrini sp. n., D. sklodowskii sp. n., D. stradinsi sp. n, D. valainisi sp. n. and D. vivesi sp. n. New faunistic data for 17 species are given. A check-list for the genus Doliops Waterh. is proposed. The key for determination of species related to D. curculionoides Waterh. is given. The shape of the aedeagus is employed in the determination of Doliops Waterh. for the first time. To the present day, 42 species (including new) of the genus Doliops Waterh. are known, which are distributed in the Philippine archipelago and some islands south of Taiwan. Source

In the present work, a cold solvent trapping (CST) and solid-phase adsorption (SPA) methods for determining concentration of tar compounds have been chosen for comparison. When the cold solvent trapping method is used, the producer gas flows through a series of impingers containing 2-propanol, whereas in a solid-phase adsorption method it passes through two adsorbent cartridges loaded with 500 mg of aminopropyl-bonded silica, and 100 mg of activated coconut charcoal. During the experiment, 52 compounds were identified by the cold solvent trapping method and 48 compounds by the solid-phase adsorption method. The SPA method is more accurate than those using impingers, especially for determining such volatile organic compounds as benzene, toluene, and xylenes, due to the use of a second sorbent, activated coconut charcoal. By contrast, the CST method proves to be more accurate for determining components of heavy tar due to a much larger volume of the sampled gas. © 2012 Elsevier Ltd. All rights reserved. Source

The type and additional material from adjacent territories of species of the genus Lesteva Latreille, 1797 of Iran are revised. Eight species are recognized, three of which are described as new: L. (s.str.) frischi sp.n. (Iran, Esfahan), L. (s.str.) schawalleri sp.n. (Iran, Elburs) and L. (s.str.) antennata sp.n. (Iran, Golestan). Two synonyms are proposed: L. (s.str.) binotata Reitter, 1901 = L. (s.str.) syriaca Luze, 1903, syn. n., L. (s.str.) longoelytrata longoelytrata (Goeze, 1777) = L. (s.str.) soror Smetana, 1967, syn. n. A key to species known from Iran and new provincial records for L. (s.str.) binotata Reitter, L. (s.str.) longoelytrata longoelytrata (Goeze), L. (s.str.) maculipennis Luze, 1903 and L. ( Lestevidia ) punctata Erichson, 1839 are provided. L. (s.str.) binotata Reitter and L. (s.str.) maculipennis are redescribed. Aedeagi of all new species, L. (s.str.) binotata, L. (s.str.) longoelytrata longoelytrata and L. (s.str.) maculipennis, as well as the antennae of all species and the variability of elytral maculae for two redescribed species are illustrated.

Eigenvector centrality is a linear algebra based graph invariant used in various rating systems such as webpage ratings for search engines. A generalization of the eigenvector centrality invariant is defined which is motivated by the need to design rating systems for bipartite graph models of time-sensitive and other processes. The linear algebra connection and some applications are described. © 2011 Wiley Periodicals, Inc. Source

Lesteva (s.str.) hartmanni sp. n. (Nepal: Gandaki Province, Manaslu Mts.), L. (s.str.) brevipennis Cameron, 1941 and L. (s.str.) torrentum Cameron, 1924 are (re-) described and illustrated. New records of L. (s.str.) championi Lohse, 1982, L. (s.str.) jaegeri Shavrin, 2012 and a modified identification key to the species of Lesteva Latreille, 1797 of Nepal are provided. L. brevipennis is recorded from Pakistan for the first time. Copyright © 2015 Magnolia Press. Source
