Language:
English
Description:
Článek se zabývá některými vlastnostmi nevalenčních doplnění ve španělštině. Zkoumá hranici mezi valenčními a nevalenčními doplněními a posuzuje vhodnost některých formálních testů pro rozlišování mezi oběma typy. Jádrem článku je sémantická klasifikace nevalenčních doplnění španělských adjektiv, doplněná o charakteristiku jednotlivých sémantických tříd. V závěru je věnována pozornost adjektivům složeným z adjektiva a jeho nevalenčního komplementu.

Description:
Keplerův spis Astronomia nova představuje jedno z nejvýznamnějších astronomických děl všech dob. Obsahuje odvození vztahů, jimž dnes říkáme první a druhý Keplerův zákon pohybu planet. Kepler zde uplatnil nový přístup k astronomii, fyzice a vesmíru vůbec, když vyšetřoval eliptickou dráhu, po níž se Mars pohybuje kolem Slunce. Vysvětlení pohybu Marsu pojal nejen geometricky, ale využil i fyzikální magnetickou hypotézu., Kepler's Astronomia nova is one of the most important astronomical texts ever written. It contains what are known today as Kepler's first two laws of planetary motion. Kepler created a new approach to astronomy, physics of the heavens, based upon an examination of the motion of Mars, which is moving around the Sun on an elliptical path. The interpretation of the motion of Mars was not based only on geometrical demonstrations but also on a physical magnetic hypothesis., Vladimír Štefl., and Obsahuje bibliografii

4. Review of microsporidia-mosquito relationships: from the simple to the complex

Microsporidia, mosquito, Brachiola algerae, Vavraia culicis, and Edhazardia aedis
Language:
English
Description:
Microsporidia in mosquitoes can be divided into two categories based on their life cycles and host-parasite relationships. Some species of microsporidia exhibit simple life cycles with one spore type responsible for oral (horizontal) transmission. They affect only one generation of the mosquito and are not usually host or tissue specific. Brachiola algerae (Vavra et Undeen, 1970) and Vavraia culicis (Weiser, 1947) are examples of species isolated from mosquitoes with relatively straightforward life cycles (one spore type) and simple host-parasite relationships. B. algerae and a close relative of V. culicis have also been isolated from a vertebrate (human) host but sources for these infections are unknown. In contrast to B. algerae and V. culicis, polymorphic (heterosporous) microsporidia in mosquitoes are characterized by complex life cycles involving multiple spore types responsible for horizontal and vertical transmission. They affect two generations of the mosquito and some involve an obligate intermediate host. These microsporidia are generally very host and tissue specific with complex developmental sequences comprised of unique stages and events. The microsporidium Edhazardia aedis (Kudo, 1930) is a pathogen of Aedes aegypti and does not require an intermediate host. The developmental cycle of E. aedis is characterized by four sporulation sequences, two in the parental host and two in the filial generation. Recent speculation relative to the source of B. algerae human infection have implicated infected mosquitoes and raised concerns about the safety of mosquito microsporidia in general. The subject of this review is to compare and contrast three species of microsporidia from mosquitoes, two with broad host ranges (B. algerae and V. culicis) and one specific to mosquitoes (E. aedis). This review describes features that distinguish mosquito-parasitic microsporidia with simple life cycles and broad host ranges from truly mosquito-specific microsporidian parasites with complex life cycles.

5. Studies on the development of Anguillicola crassus Kuwahara, Niimi et Itagaki, 1974 (Nematoda: Dracunculoidea) in the intermediate host

Subject:
Nematoda, Anguillicola, eel, Copepoda, and development
Language:
English
Description:
The development of the nematode Anguillicola crassus, a swimbladder parasite of eels, was experimentally studied in copepod intermediate hosts Cyclops strenuus and Acanthocyclops vernalis. The copepods, kept at a laboratory temperature of 20-22 °C, were infected with nematode second-stage larvae; the second moult of larvae (the only one in the intermediate host) was observed to start 10 days p,i„ but third-stage larvae liberated from their cuticular sheath were first observed 20 days p.i. These proved to be infective for experimental eels. Free second-stage larvae as well as larvae from copepods were described. The morphology of A. crassus larvae and the mode of their development in the intermediate host were compared with those of other dracunculoid nematodes. From this point of view, Anguillicola members appear to represent an ancient group of dracunculoid nematodes.
