This species was described from three females from Buryatia. It was diagnosed as having more vertical coils of insemination ducts wrapping the receptacle than in <i>L. stigmatisata</i>. Danilov (1994) misidentified <i>L. stigmatisata</i>, a species absent in Siberia, and actually compared his new species with <i>L. alberta</i> Gertsch, 1946. <i>Lathys truncata</i> differs from both species (<i>L. stigmatisata</i> and <i>L. alberta</i>) by having white guanine spots on the dorsum of the abdomen. It seems that this species inhabits tree trunks and cliffs. Danilov (1994: fig. 34) illustrated an epigyne with two vertical loops of insemination ducts as in specimens from Almaty Area (Fig. 44). Another figure (Danilov 1994: fig. 35) shows an epigyne with three loops as in all specimens we examined from Buryatia (Fig. 43).

On the Danilov-Gizatullin isomorphism theorem
No full text6 pagesInternational audienceA Danilov-Gizatullin surface is a normal affine surface V=F d\S, which is a complement to an ample section S in a Hirzebruch surface Fd. By a surprising result due to Danilov and Gizatullin, [DaGi] V depends only on n=S^2 of S and neither on d nor on S. In this note we provide a new and simple proof of this Isomorphism Theorem
Ammophila kowalczyki Olszewski & Danilov 2020, sp. nov.
No full textAmmophila kowalczyki Olszewski sp. nov. Fig. 1 A–M Etymology. The species is named after my friend Jan Krzysztof Kowalczyk from Gdynia, Poland, an expert in Polish Aculeata. Type material. Holotype, ♂, IRAN: Kerman, Gohargaz [N30.43753, E57.21039], 2020 m a.s.l., 9 May 2017, leg. Iran Expedition IV, in coll. NHMUK; Paratype, ♀, Iran: Kerman, Gohargaz [N30.43753, E57.21039], 2020 m a.s.l., 13 May 2017, leg. Iran Expedition IV, in coll. NHMUK. Diagnosis. In Ammophila kowalczyki, the metasomal apex is black with a metallic lustre, and the propodeal enclosure is wholly glabrous and transversely striated (Fig. 1I). The pronotal collar and scutum are distinctly ridged transversely (Fig. 1G, H). The male shares a blunt tooth on the hypostomal carina with A. abnormis Dollfuss, 2013, A. horni von Schulthess, 1927 and A. punctata F. Smith, 1856; of these species, only A. abnormis has a wholly glabrous propodeal enclosure, and it shares a similarly shaped clypeus with the new species. The male of A. kowalczyki differs by the gonostyle with distinct, long preapical spines, the shape of the cuspis (wide and not visibly tapering) and the shape of the penis valve (Fig. 1E). In A. abnormis, the gonostyle has at most a few short preapical spines and a slender, characteristically tapering cuspis. The penis valve has no preapical spines. Both sexes of A. kowalczyki resemble A. gussakovskii Dollfuss, 2013 in having a distinct patch of appressed silvery setae on the mesopleuron and a glabrous propodeal enclosure. Also, the pronotal collar and scutum are transversely striate and the gastral apex has a metallic lustre. The male of A. kowalczyki differs in having the hypostomal carina with a tooth near the mandibular socket. The female of A. kowalczyki differs by the appressed silvery setae over the whole mesopleuron except for its upper part. Description. Female. Body length 16 mm. Head (Fig. 1C). Clypeal disk sparsely punctured medially. Clypeus weakly elongate ventrally, with appressed silvery setae in basal part. Median lobe of clypeus emarginate (Fig 1C). Subantennal sclerite with appressed silvery setae. Gena, vertex and frons with long separate white setae and mandible with long separate dark setae. Supra-antennal lamellate projection absent. Frons and vertex dull. F1: F2 = 6.2: 3.2. Mesosoma. Pronotum not elongate. Propodeal enclosure glabrous, obliquely striated. Mesopleuron with appressed silvery setae concealing sculpture (except for its upper part), metapleuron irregularly rugose, striated. Scutellum and metanotum longitudinally striated. Propleuron with dense appressed silvery setae and long separate white setae. Legs. Coxae with dense appressed silvery setae dorsally. Claws without basal tooth. Fore wing with three submarginal cells. Submarginal cell III not petiolate. Marginal cell with rounded apex. Colouration. Head, mesosoma, legs entirely black. Wings hyaline; venation dark brown. T4 and 2/5 of T5 laterally, tegula, petiole, T1–T3, and S1–S5 red. Other parts of metasoma black with metallic lustre. Male. Head, mesosoma, and metasoma as in female except for the following: Body length 16 mm. Head (Fig. 1D). Clypeus elongate, medially with one prominent teeth (Fig. 1D), elevated in lateral view, with dense appressed silvery setae concealing sculpture except for apical margin. Hypostomal carina with tooth near mandibular socket (Fig. 1J). Mandible with sparse long white and dark setae. F1: F2 = 5.5: 3.2. Scutum finely transversely striated anteriorly, distinctly obliquely striated posteriorly (in male more so than in female). Male genitalia (as illustrated (Fig. 1 E–F). Gonostyle with long preapical spines (Fig. 1E), penis valve without preapical spines (Fig. 1E). Cuspis wide, not visibly tapering (Fig. 1F). Colouration. T4, ⅔ of T5, ½ of T6, ¼ of T7 laterally, pronotal lobe, petiole, T1–T3, and S1–S7 red. Other parts of metasoma black with metallic lustre.Published as part of Olszewski, Piotr & Danilov, Yuriy N., 2020, New species and records of the genus Ammophila W.

Fundamentos epistemológicos da ciência Didática: contribuições de Mikhail A. Danilov
No full textThe aim of this paper was to show the main contributions of the Russian didactician Mikhail A. Danilov (1899-1973) for the consolidation of the Didactic as an independent science. These contributions are shown as the ones that are considered the main nucleus of the categories that can define the Scientific Didactic: philosophical fundamentals, concept, object, laws, scientific principles and tasks of this science. The theoretical referential has been the Materialistic Dialectic and the Developmental Didactic. The methodological proceedings were the critical analysis of the author publications: the contextualization of his thinking with the philosophical sources, as well as publications of other didacticians concerned about the same questions. The result was a new synthesis of the didactic thinking of M.A. Danilov, mixed by other sources and authors. The paper shows the main categories of the Didactic science, becoming a tool for the didactic-pedagogical formation of students and teachers at work. Keywords: epistemological foundations, didactic science, didactic categories, Mikhail A. Danilov.O propósito deste artigo consiste em apresentar as principais contribuições do didata russo Mikhail A.

O referencial teórico tem sido a Dialética Materialista e a Didática Desenvolvimental. Os procedimentos metodológicos foram a análise crítica das obras do autor, a contextualização de seu pensamento com as fontes filosóficas, assim como com a obra de outros didatas que apresentam preocupações similares às do autor. O resultado foi uma nova síntese do pensamento didático de M.A. Danilov, cotejado com outras fontes e autores. O artigo apresenta as categorias principais da ciência Didática, tornando-se uma ferramenta para a formação pedagógico-didática de estudantes e professores em exercício.Palavras-chave: fundamentos epistemológicos, ciência didática, categorias da didática, Mikhail A.

"Memoirs" of major M. V. Danilov as a model of Utopia-Eupsychios of Russian Enlightenment
No full textThe article considers “Memoirs” of major M. V. Danilov as a variant ofUtopia-Eupsychios. The aim of the utopia is to give a model of ideal existence of personality in the age of Enlightenment in Russia.The author proposes to use the term “Utopia as a reality” to describethe personal reminiscences of this kind of Utopia. The author analyzedM.V. Danilov's memoirs and comes to the conclusion that the poem “AnEssay on Man” by the English poet A. Pope was the literally model for thememoirist. Anthropocentric problem of the poem became the object of imitation for the author of the memoirs, who managed to create one of the first variants of family-everyday life memoirs in the 1770s in Russia.В статье рассматриваются "Записки" майора М. В. Данилова как текст, представляющий собой вариант утопии-эвпсихии, ставящей своей целью дать образец идеального бытия личности в эпоху русского Просвещения. Автор статьи предлагает использовать для характеристики мемуарного варианта данного вида утопий термин "утопия как реальность". В ходе анализа "Записок" М. В. Данилова автор приходит к выводу, что литературным образцом для создания "утопии как реальности" для мемуариста была поэма "Опыт о человеке" английского поэта А. Поупа. Антропоцентрическая проблематика поэмы стала объектом для подражания для автора записок, которому удалось в 70-е годы XVIII века создать один из первых вариантов семейно-бытовых мемуаров в русской словесности

On the role of saturation in modeling ionic transport in the electrolyte of (Lithium ion) batteries
No full textRecent computational simulations of ionic conductivity across the electrolyte of commercial batteries by Salvadori et al. (2015) have shown that the concentration of ions exceeds half the saturation limit near the electrodes. This observation, which is in agreement with other approaches by Danilov and Notten (2008), implies that the widespread assumption of infinite dilution far from saturation is questionable. The present contribution is therefore devoted to investigate the role of saturation in modeling ionic transport in the electrolyte of Li-ion batteries. An important result is found, that saturation has no effect on the diffusivity, whereby the condition of electroneutrality is well approximated in the solution. However saturation affects the electric potential up to 40% near the electrodes for all charge rates

On the synonymy of Dactylopisthoides Eskov, 1990 and Uusitaloia Marusik, Koponen & Danilov, 2001 (Araneae, Linyphiidae)
No full textTwo erigonine genera from East Siberia are synonymized: Uusitaloia Marusik, Koponen & Danilov, 2001, syn. nov. = Dactylopisthoides Eskov, 1990. Two new combinations are established: Dactylopisthoides transbaicalicus (Marusik, Koponen & Danilov, 2001), comb. nov. and Dactylopisthoides wrangelianus (Marusik & Koponen, 2009), comb. nov. both ex. Uusitaloia. The epigyne of D. wrangelianus is illustrated for the first time. A new, updated diagnosis of Dactylopisthoides is proposed. The copulatory organs of both sexes of D. hyperboreus and D. wrangelianus are illustrated by SEM images
