14373. Metamorfózy izraelské pravice: od Revizionistické unie po vznik Gachalu, 1925-1965

Language:
Czech
Description:
At first glance, the Israeli right might be regarded as a sort of monolith. Characterized by intransigence vis-à-vis the great powers (initially the British) and the Arabsalike and with iconic strongmen at the helm, both the post-independence Herut party and its interwar predecessor(s) clearly demonstrated to the outside world what Zionist maximalism stood for, particularly in terms of its political and terriotiral demands. on a closer look, however, many of the sought after parallels between the interwar Zionist right and the post-independence Israeli right are more imagined than real. in fact, not only were the particular groupings made up of different sets of players (often in opposition to each other), but their very worldviews differed, sometimes fundamentally. After all, the paramilitary groups from which the Israeli right developed had self-distanced themselves from any sort of reliance on political means or international guarantees, rejecting the very notions which had stood at the core of interwar Revisionism, the alleged forefather of the Israeli right., Jan Zouplna., and Obsahuje bibliografii

Description:
The gills of 63 specimens of the Atlantic bluefin tuna Thunnus thynnus (Linnaeus) (Osteichthyes: Scombridae) from three localities of the Mediterranean (Sardinian, Tyrrhenian and Levantine Seas) were examined for metazoan parasites. The parasite fauna of T. thynnus from the Sea of Sardinia included 11 species: five didymozoid trematodes, three capsalid and one hexostomid monogeneans, and one caligid and one pseudocycnid copepods. Four didymozoids were found in fish from the Levantine Sea and only one didymozoid was recorded in fish from the Tyrrhenian Sea. Dividing the hosts into four size-groups (small, medium-sized, large and extra large), the pairwise comparison of prevalence and mean abundance of the new and literary data) showed differences according to host size. The differences in the composition of the parasitic faunas and in the prevalence of parasites, observed between the small tunas from the Tyrrhenian Sea and the medium-sized tunas from the Adriatic Sea, Levantine Sea and the North-East (NE) Atlantic Ocean, indicated that these groups form discrete units. The parasite fauna of the large tunas from the Sea of Sardinia is the richest among the bluefin tuna populations of the Mediterranean and the NE Atlantic, due to the presence of species not found elsewhere in bluefin tunas, such as Caligus coryphaenae Steenstrup et Lütken, 1861, Capsala magronum (Ishii, 1936) and C. paucispinosa (Mamaev, 1968). This fact and the prevalence of some parasites of this group (lower than those of medium-sized fish from the NE Atlantic and higher than the small and medium-sized tunas from the Mediterranean) suggest that the large-sized tuna group in the western Mediterranean is formed by Mediterranean resident tunas (poorly infected), and by tunas migrating from the Atlantic Ocean (heavily infected).

14377. Meteor physics

Pecina, P.
Format:

Type:
model:article and TEXT
Subject:
meteor physics, meteoroid flights, and space research
Language:
Czech
Description:
Some comments on problems connected with our knowledge and understanding of events observable during the meteoroid flight through the atmosphere are presented. The review is divided into three parts. Tbe first part deals with the section of flight characterized by the increase of body temperature from the value reached at the heliocentric distance 1 AU, i.c. at the frontier of the Earth´s atmosphere, which was estimated to be approximatelly 280° K, to the temperature at which the evaporation of the meteoroid can start. This process is designated as pre-ablation heatlng. The second part deals with efects connected with the visible trajectory as well as with ionization trails and problems related to them. There exists generic connection between luminous flight of meteoroids and dark flight with possibility of finding the meteorites fallen to the ground namely with the predictabllity of the impact area and the impact itself. This is the subject of the third part.

14378. Meteoritic iron artefacts redux

meteoritic iron, nickel, bloomery iron, archaeometallurgy, prehistory, Early Middle Ages, meteoritické železo, nikl, svářkové železo, archeometalurgie, pravěk, and raný středověk
Language:
Czech
Description:
The earliest iron artefacts are often presented as products made of meteoritic iron, which is characterised by its high iron content. However, recent studies have shown that high nickel and iron content cannot be taken as a firm criterion for establishing its meteoritic origin. The most effective tool for helping to specify the elemental composition in such cases is a metallographic analysis. It turns out that the material of many artefacts regarded as having been forged from meteoritic iron could in fact be bloomery iron. An analysis of ample yet scattered evidence suggests that the production of items from meteoritic iron could in fact be irregular and sporadic and Nejstarší železné artefakty jsou namnoze prezentovány jako výrobky z meteoritického železa, jehož typickým rysem je vysoký obsah niklu. Nedávné studie však ukázaly, že vysoké obsahy niklu v železe nelze brát jako pevné kritérium pro stanovení jeho meteoritického původu. Nejúčinnějším nástrojem, který v takových teriál mnoha předmětů, které jsou považovány za výkovky z meteoritického železa, může být ve skutečnosti železem svářkovým. Analýza četné, byť porůznu rozptýlené evidence nasvědčuje tomu, že výroba předmětů z meteoritického železa mohla být ve skutečnosti prostorově nerovnoměrná a sporadická.

14379. Meteoroid streams associated with Apollo asteroids: evidence from the Adelaide radar orbit surveys

Subject:
Apollo asteroids, meteoroid streams, and meteor orbits
Language:
Czech
Description:
Since the discovery of Phaethon (the 'Geminid asteroid') in 1983 there has been renewed interest in the association of meteor showers with Earth-approaching asteroids. In the past the existence of several streams associated with different asteroids (in particular Adonis, Apollo, Hermes and Oljato) has been suggested but not proven. Here the 3759 meteor orbits determined at Adelaide in the 1960's have been compared to the orbits of all known Aten-Apollo-Amor asteroids using a new and powerful search technique. Strong evidence is found for streams associated with Apollo-type asteroids Icarus, Hermes, Adonis, Oljato, Hephaistos, 5025 P-L, 1982 TA, and 1904 KB;, the final five in this list may be members of the Taurid-Arietid complex, as is Comet P/Encke. No stream associated with 1862 Apollo was identified, but this may be due to the lack of observations at the appropriate solar longitude. No streams associated with any Aten or Amor asteroid were found: this may be due to the limited detectability of their meteors, if they exist, because of their low geocentric velocities. In general streams were discovered for all asteroids coming within 0.1 AU of the Earth, having radiants observable from Adelaide and atmospheric velocities above about 22 km/sec : this suggests that meteoroid streams are a general feature of Earth-approaching asteroids.

Description:
Článek podává přehled o současném systému operativních meteorologických družic, a to z pohledu technického, legislativně-komerčního a uživatelského. Podrobnější informace jsou zaměřeny především na ty družice, které jsou v současnosti přijímány a využívány v České republice (americké polární družice NOAA, evropská geostacionární družice Meteosat), resp. jejichž nasazení se plánuje během následujícího roku (MSG). Vedle zpracování a využití obrazových dat si článek též všímá i zpracování a využití dat z družicové sondáže atmosféry - jak radiometrické, tak s využitím družic systému GPS.
