We present additional evidence in support of our prevlous work (Crifo, 1987 bc) in which, from theoretical fits to Comet Halley
near -to far- infrared emissions, based on the in-situ flyby probes data, we estimated that the comet was losing half or more of its mass under the form of large (> 1 gram) grains of small (0.3 g cm-^3) density. We confirm that the comet dust-to-gas mass loss rate ratio lies somewhere between the values 0.80 and 18.6, with a best estimate at 3.46. We discuss this result in the context of the general agreement that comets loose less than half of their total mass loss in dust, and this dominantly at very smáli grain sizes. We trace this agreement back to overconfidence placed in a model size distribution which inherently excludes substantial mass loss in
large grains without appropriate experimental justification.
Ceremonial inauguration of Tokamak Compass-D that Czech Republic obtained as gift from Great Britain took place in April 1 2008 by participation e.g. chairman of AS CR Václav Pačes, ambasador of United Kingdom of Great Britain and Northern Ireland Linda Joy Duffield, director of Association EUROATOM-IPP.CR Hardo Bruns and director of UKAEA Fusion Sir Chris Llewellyn Smith. A Tokamak Compass-D is a machine producing a toroidal magnetic field for confining a plasma. It is one of several types of magnetic confinement devices and the most researched candidate for producing fusion energy. and Marina Hužvárová.
V nasledujúcich riadkoch sa pokúsim dokázať, že ak sudcovia preferujú formalistickú právnu argumentáciu, tak potom nie v dôsledku toho, akú majú teoretickú koncepciu práva, ale v dôsledku toho, v akých spoločensko-politických pomeroch pôsobia. Formalizmus v právnej argumentácii nie je pojem, ktorého zmysluplné použitie nutne predpokladá teóriu právneho pozitivizmu a ktorého opodstatnenie nutne predpokladá autoritu tvorcu práva. Ak sa formalizmus v nejakej právnej kultúre etabluje, tak potom
zrejme kvôli výsledkom, ktoré generuje; kvôli tomu, že chráni hodnoty, ktoré chcú chrániť aktuálni držitelia moci, či už pod nimi rozumieme politickú elitu, spoločenskú triedu, predstaviteľov kultúrnej väčšiny alebo ľud ako celok. To prirodzene limituje aj schopnosť formalizmu riešiť tzv. koordinačný problém. and In the following pages I will try to prove a thesis according to which, when judges prefer
formalistic legal argumentation, they do not do so because of their theoretical conception of law but
because of the political and social conditions in which they happen to serve their office. Formalism
in legal argumentation is not a concept which is meaningful only against the backdrop of legal
positivism and which is justified only by the authority of a lawmaker. When formalistic argumentation
becomes embedded with the respective legal culture it is apparently so because of the results
it generates; because it protects values which current power holders want to be protected, whether
we understand them as political elite, social class, representatives of cultural majority or the people
as a whole. This naturally limits the capacity of formalism to solve the coordination problem.
Invazivní metody léčby chronické formy ischemické choroby srdeční byly po dlouhou dobu považovány za kauzální terapii, která bezpochyby snižuje morbiditu a mortalitu nemocných. Na druhé straně životní styl a farmakologická terapie byla nahlížena jako spíše doplňující, ale nikoliv rozhodující léčba. V posledních letech je možno vidět změnu v pohledu na ischemickou chorobu srdeční. Je to mnohem difuznější proces v koronráním řečišti a není to tedy jen otázka kritických stenóz, ale stejně nemocného ohrožují i další úseky věnčitých tepen, kde se hovoří o vulnerabilních placích. Překvapením pro experty byly závěry řady studií potvrzujících neschopnost invazivch metod prodloužit život nemocným s chronickou formou ICHS. Na druhé straně přibývají důkazy o významném vlivu úpravy životního stylu a rozrůstajících se možnostech farmakolgoické terapie s pozitivním vlivem na morbiditu a mortalitu. Článek prezentuje současné názory na tyto otázky, které jsou nyní živě diskutovány., Invasive methods for treatment of coronary artery disease in chronic form were, for a long time, believed to be causal treatment that definitely diminish patient morbidity and mortality. By contrast, lifestyle and pharmacological therapy were seen as valuable but not lifesaving. In the last few years a change can be seen in the view on coronary artery disease. It is a much more diffusive and complicated process in the coronary tree. It is not merely a question of the critical stenotic areas; the new idea of vulnerable plaque, which presents the same danger of complication as critically stenotic areas, is also important. A great surprise for experts was the result of various studies confirming the inability of invasive procedures to prolong life in patients with chronic coronary disease. On the other hand, there has been more evidence that lifestyle changes and expanding pharmacological possibilities can have a significant positive effect on morbidity and mortality. This article aims to present the problem as it is currently being discussed., and Kotík L.
