Five species of adult nematodes, unidentifiable nematode larvae, and three species of acanthocephalans, were found in freshwater ornamental fishes newly imported into Germany from Brazil, Colombia, Indonesia, Malaysia, Nigeria, Peru, Sri Lanka and Thailand. The following species were identified: Adult Nematoda: Pseudocapillaria tomentosa, Capillariidae gen. sp., Dichelyne hartwichi sp. n., Procamallanus (Spirocamallanus) pintoi and Spinitectus allaeri·, Acanlhocephala: Pseudogorgorhynchus arii gen. et sp. n., Neoechinorhynchus sp. and Pallisentis sp. The nematode Dichelyne hartwichi sp. n. (male only) from the intestine of Chelonodon fluviatilis (Hamilton) from Thailand is characterised mainly by the presence of minute cuticular spines on the tail tip, length of spicules (510 pm) and arrangement of caudal papillae. The acanthocephalan Pseudogorgorhynchus arii sp. n. from the intestine of Ariopsis seemanni (Günther) from Colombia represents a new genus Pseudogorgorhynchus gen. n., differing from other genera of the Rhadinorhynchidae mainly in possessing a small proboscis armed with markedly few (18) hooks arranged in six spiral rows. Spinitectus macheirus Boomker et Puylaert, 1994 and Spinitectus moraveci Boomker el Puylaert, 1994 are considered junior synonyms of Spinitectus allaeri Campana-Rouget, 1961
The present paper comprises a systematic survey of nematodes found in 88 specimens of 24 species of freshwater fishes in Venezuela in 1992 and 1994. The following 13 species of nematodes were recorded: Adults: Guyanema longispiculum Moravec, Prouza et Royero, 1996, Guyunema sp., Procamallanus (Spiracamallanus) inupinatus Travassos, Artigas et Pereira, 1928, P. (S.) krameri (Petter, 1974) comb, n., P. (S.) pintoi (Kohn et Fernandes, 1988) comb, n., Procamallanus (Spiracamallanus) sp., Ruphidascaris (Sprentascaris) mahnerti (Petter et Cassone, 1984). Larvae: Anisakidae gen. sp., Brevimullicaecum sp., Ctmtracaecum sp. Type 1, Contracaecum sp. Type 2, Contracaecum sp. Type 3, Eustrongylides sp. All these parasites are reported from Venezuela for the first time and all findings represent new host records. Brevimulticae-cum larvae are reported from fishes for the first time. Almost all parasites are briefly described and illustrated and problems concerning their morphology, taxonomy, hosts and geographical distribution are discussed. A new name, Terranova diazungriai nom. nov. is proposed for T. caballeroi Diaz-Ungrfa, 1968 (a junior homonym of T. caballeroi Baruš et Coy Otero, 1966).
Three species of planktonie crustaceans, Cyclops strenuus and Macrocyclops alhidus (Copcpoda) and Notodromas monacha (Ostracoda), were experimentally infected with the eggs and second-stage larvae of the swimbladder nematode Anguillicola crassus originating from eels from Neusiedler Lake in Austria. At 20-22°C, third-stage larvae of the parasite developed in all these invertebrate hosts within 16-20 days p.i. Ostracods harbouring the nematode third-stage larvae (33 days p.i.) were fed to small eels (Anguilla anguilla), while infected copepods (20 days p.i.) to seven other fish species. By these experiments, the larvae from ostracods proved to be infective for the definitive host and the ostracod was thus confirmed as a true intermediate host of Anguillicola crassus. Notodromas monacha represents a new experimental intermediate host of A. crassus and the second known invertebrate other than a copepod in which the larval development of this nematode up to the infective stage takes place. Five species of fish, cyprinids Tinca tinea, Alhumus alburnus, Gobio gobio and Albumoides bipunctatus (the latter representing a new host record), and guppy, Poecilia reticulata, were found to serve as experimental paratenic hosts for A. crassus, in which the live nematode infective larvae were recorded 49 days p.i.
Článek přistupuje k problematice aktuálního členění větného z hlediska překladatelského. Na srovnání tří českých překladů jednoho literárního textu jsou demonstrována překladatelská úskalí způsobena rozdílnou hierarchizací jednotlivých indikátorů AČV v angličtině a češtině. Pozornost je věnována především primární roli kontextu v rámci jednotlivých prostředků AČV a tomu, jak tuto tezi překladatelé v praxi respektují. Naznačen je i problém záměrného porušování zákonitosti AČV v literárním textu.

In this work, the set of procedures to prepare the GPS vector solutions time series (VSTSGPS) to spectrum analyses is presented. This preparation is shared on two stages. In the first stage, the breaks filling was processed. This stage was achieved in two steps. Firstly, the breaks filling was computed on the base of time series of other vectors. Secondly, the breaks filling was computed using the interpolation or extrapolation methods. The next stage of VSTSGPS preparing implicated the time series smoothing to remove the impulse noises. After breaks filling and smoothing the VSTSGPS were tested for admission to further analyses., Daniel Jasiurkowski., and Obsahuje bibliografické odkazy
Among the programmes aimed at developing a standard model for properties and state of the Earth’s crystalline crust, those dealing with drilling the Kola (SG-3), Ural (SG-4) and German (KTB) superdeep boreholes yielded the most interesting results. No marked depth dependence of rock volume density and seismic wave velocities was observed in the sections of SG-3 and SG-4. A new result of the investigations is the discovery of strongly anisotropic rocks in the SG-3, SG-4 and KTB sections. In the massifs of the Kola and German superdeep boreholes such rocks constitute the majority of the drilled sections. The presence of the velocity anisotropy as well as the complex structure of the rocks composing crystalline metamorphosed sequences greatly hamper the interpretation of the results obtained from the seismic survey conducted at the surface., Felix F.
