The origins of this partial source research are linked to the preparation of Dvofiák’s works for piano for publishing in the frame of the Nové souborné vydání dûl Antonína Dvofiáka (The New Dvofiák Edition, NDE). This article considers the available sources and the history of origin and publication of Dvofiák’s two piano pieces, Dumka op. 12,1 and Furiant op. 12,2. It adds new information to the previous research, and intreprets the existing sources in a new way
The current article considers some infinite groups whose finitely generated subgroups are either permutable or pronormal. A group G is called a generalized radical, if G has an ascending series whose factors are locally nilpotent or locally finite. The class of locally generalized radical groups is quite wide. For instance, it includes all locally finite, locally soluble, and almost locally soluble groups. The main result of this paper is the following Theorem. Let G be a locally generalized radical group whose finitely generated subgroups are either pronormal or permutable. If G is non-periodic then every subgroup of G is permutable.
Four new species of the genus Hatschekia Poche, 1902 (Copepoda: Siphonostomatoida: Hatschekiidae) are described based on female specimens collected from pufferfishes (Tetraodontiformes: Tetraodontidae) caught in coastal waters off the Ryukyu Islands, Japan: H. longiabdominalis sp. n. on Arothron hispidus (Linnaeus), H. geniculata sp. n. on A. hispidus (type host) and A. stellatus (Bloch et Schneider), H. ellipsocorpa sp. n. on A. mappa (Lesson), and H. boonah sp. n. on A. nigropunctatus (Bloch et Schneider) (type host) and A. meleagris (Schneider). Hatschekia longiabdominalis sp. n. and H. boonah sp. n. differ from all other congeners by sharing an unusual, projected abdomen and a fusiform trunk with posterior lobes; these two species are differentiated from each other by the shape of the dorsal chitinous frame on the cephalothorax. Hatschekia geniculata sp. n. can be distinguished by the combination of the following morphological characters: a rhomboidal cephalothorax with a pair of lateral conical protrusions, a cylindrical trunk with posterior lobes and a bent abdomen with a dorsal protrusion. Hatschekia ellipsocorpa sp. n. resembles H. pholas (Wilson, 1906) but can be distinguished from the latter by the possession of one distal and one inner setae on the terminal endopodal segment of legs 1 and 2. Hatschekia pholas is also redescribed based on female specimens from the tetraodontid A. stellatus. At present, 44 nominal species of the genus have been reported from Japan, including four new species described in this paper; 38 of them have been described originally from Japan.
Hyalomma (Euhyalomma) lusitanicum Koch, 1844 and Hyalomma (Euhyalomma) franchinii Tonelli Rondelli, 1932 are amongst the most poorly studied of those species within the genus Hyalomma Koch, 1844 that are restricted to the Mediterranean region. No comprehensive morphological study has been done to date, and the immature stages of H. (E.) franchinii have not been described. Here all the parasitic stages of H. (E.) lusitanicum and the adults of H. (E.) franchinii are redescribed, and the immature stages of the latter species are described for the first time. Data on hosts, geographic distribution and disease relationships are provided.
