Two species of the genus Baruscapillaria Moravec, 1982 are known to parasitise the small intestine of the common cormorant, Phalacrocorax carbo (L.): Baruscapillaria carbonis (Dubinin et Dubinina, 1940) and B. rudolphii Moravec, Scholz et Našincová, 1994. A redescription of the former species, based on specimens collected from common cormorants shot in South Bohemia, Czech Republic, is provided. Morphological features distinguishing B. carbonis and B. rudolphii are specified. B. carbonis is characterised mainly by the well-developed membranous bursa in the male, composed of five distinct lobes (four lateral and one spur-shaped dorsal); the length of the spicule is 1.9-2.3 mm; gravid females are provided with a long vulvar appendage. Males of B. rudolphii have reduced, bi-lobed membranous bursa and the spicule is 0.9-1.3 mm long; the vulvar appendage is absent in gravid females. This is the first record of B. carbonis in the Czech Republic.
V astronomické a fyzikální komunitě panuje všeobecné přesvědčení, že dodatečně relativistické stáčení perihelia dráhy Merkuru 43" za století je již dávno a mnohokrát prověřená hodnota, na které není třeba nic měnit. Že je dána rozdílem pozorovaného stáčení perihelia Merkuru a počítaného stáčení pomocí Newtonovy mechaniky. V tomto případě se ale odečítají dvě skoro stejně velká čísla, která jsou navíc zatížena mnoha chybami. Výsledný rozdíl 43" za století je tak nejistý a nemusí odpovídat skutečnosti., The perihelion shift of Mercury's orbit is thought to be one of the fundamental tests of the validity of the general theory of relativity. In the current (astro)physical community, it is generally accepted that the additional relativistic perihelion shift of Mercury is the difference between its observed perihelion shift and the one predicted by Newtonian mechanics, and that this difference equals 43" per century. However, as it results from the subtraction of two quite inexact numbers of almost equal magnitude, it may be subject to cancelation errors. As such, the above accepted value is highly uncertain and may not correspond to reality., Michal Křížek., and Obsahuje seznam literatury
