An examination of a sample of European eels, Anguilla anguilla (L.), collected from Lake Bracciano near Rome in 1993, the only known European locality with the occurrence of the introduced swimbladder nematode Anguillicola novaezelandiae Moravec et Taraschewski, 1988, revealed for the first time the presence of two Anguillicola species, A. novaezelandiae and A. crassus. In view of the investigations carried out by current authors in Bracciano Lake in the years 1982-1992, it is apparent that the latter species has been introduced into the lake quite recently, where it quickly became a dominant species. The development of A. novaezelandiae was experimentally studied in the copepod intermediate host, Cyclops strenuus, for the first time. The copepods were infected with nematode second-stage larvae at 21-22°C; fully developed infective third-stage larvae were obtained 13 days p.i. The general morphology of individual larval stages of A. novaezelandiae was similar to that of larvae of the related species Λ. crassus.
Five species of the genus Gobio have been recorded in Slovenia. G. albipinnatus Lukasch, 1933, G. uranoscopus (Agassiz. 1828), G.Gobio (Linnaeus, 1758) and G. kesslerii Dybowski, 1862 inhabit watercourses of the Danube River in the eastern part of Slovenia (the ecatchments of the Sava, Drava and Mura rivers). G. benacensis (Pollini, 1816 inhabits Adriatic sea basin (the catchment of the Vipava river). The last one was found in Slovenia for the first time in October 2003. In the Red List of Slovenian Freshwater Fishes and Lampreys three species G. albipinnatus, G. uranoscopus and G. kesslerii are classified as vulnerable (V). These species were proposed to be added in Annex II of Council Directive 92/43/EEC.
The fault displacement monitoring network EU-TecNet was established to define microdisplacements across faults in the territory of Central Europe (www.tecnet.cz) using three-dimensional optical-mechanical extensometers. The results of long-term neotectonic activity obtained from two caves localized in the eastern part of the Slovenský kras Mts. (SE Slovakia) show generally NE-SW oriented dilatation. This orientation is in a good accordance with the orogen-parallel extension monitored in the Western Carpathians. Differing short-lasting trends were distinguished in 2011-2012 and 2013-2015, which supports the significance of the tectonic pulse at the end of 2012 and the beginning of 2013. Moreover, simultaneous short-lasting faulting occurred at both sites under the transtensional tectonic regime, where the principal maximum compressional axis operated in a NW-SE direction (σ1). The observed results were compared to data from monitoring points in distant areas of the European plate. and Briestenský Miloš, Hochmuth Zdenko, Littva Juraj, Hók Jozef, Dobrovič Roman, Stemberk Josef, Petro Ľubomír, Bella Pavel.
We obtain a presentation for the singular part of the Brauer monoid with respect to an irreducible system of generators consisting of idempotents. As an application of this result we get a new construction of the symmetric group via connected sequences of subsets. Another application describes the lengths of elements in the singular part of the Brauer monoid with respect to the system of generators mentioned above.
The paper gives detailed overview of the prototype of autonomous mobile robot Advee, developed for presentation purposes. Mechanical, electrical, sensor and software subsystems are described in the paper together with key algorithms such as localization and motion planning. Advee already performed over 600 hours of operation among common people, the experiences gained from the operation are also summarized in the paper. and Obsahuje seznam literatury
