Photoionized features in the X-ray spectrum of Ex Hydrae

We present the first results from a long (496 ks) Chandra High Energy Transmission Grating observation of the intermediate polar EX Hydrae ( EX Hya). In addition to the narrow emission lines from the cooling post-shock gas, for the first time we have detected a broad component in some of the X-ray emission lines, namely, O VIII lambda 18.97, Mg XII lambda 8.42, Si XIV lambda 6.18, and Fe XVII lambda 16.78. The broad and narrow components have widths of similar to 1600 km s(-1) and similar to 150 km s(-1), respectively. We propose a scenario where the broad component is formed in the pre-shock accretion flow, photoionized by radiation from the post-shock flow. Because the photoionized region has to be close to the radiation source in order to produce strong photoionized emission lines from ions such as O VIII, Fe XVII, Mg XII, and Si XIV, our photoionization model constrains the height of the standing shock above the white dwarf surface. Thus, the X-ray spectrum from EX Hya manifests features of both magnetic and non-magnetic cataclysmic variables

World Peace: Rational Idea and Reality On the Principles of Kant's Political Philosophy

Kant's various teachings concerning (world) peace are characterized by a philosophically unique realism. Thereby, they are fundamentally distinguished from all preceding doctrines about peace. This thesis of realism refers to various aspects, respectively levels, of the doctrine, namely: 1) in general to the assumptions of the doctrine of Right3 altogether (ch. II); 2) in particular to the assumptions of the doctrine of eternal peace (chs. III-V); 3) to the recommendations with regard to the realization of eternal peace (chs. VI-XI); 4) to the reasons by which Kant justifies the hope with regard to eternal peace (ch. XII, XIV-XVII); 5) to Kant's strict denial of a specifically political "morals" (ch. XIII-XVII)

Особливості структури еліптичного питального речення в англійській мові ХІІ–XVII ст.

Стаття присвячена дослідженню англійського еліптичного питального речення у діахронії (XII–XVII ст.), відслідковуються особливості його структури, яка варіюється в окремо взяті періоди середньо- й ранньоновоанглійського часового відрізка. Розглядаються особливості вживання таких речень у різних за жанром текстах, визначаються основні чинники, що впливають на довжину таких питальних речень

Synthesis of a-Amino-1-Adamantylacetic and a-Amino- 2-Adamantylacetic Acid

a-Amino-2-adamantylacetic acid (VII) was obtained when 2-adamantylcyanoacetylhydrazide (IX) was subjected to Curtius rearrangement or 2-(2-adaman;tyl)-malonamic acid (XII) to Hofmann degradation. The same amino acid was obtained when ri.- bromo-2-adamantylacetic acid (VI) was •treated with ammonia. Partial hydrolysis of diethyl adamantyl-(1)-malonate (XIV) yie1ded ethyl adamantyl-(1)-malcmate (XV) which, after treatment with thionyl chlodde and then ammonia, gave 2-(1-adamantyl)- malonamic acid ethyl ester (XVII). Hofmann degradation of 2-(1 -adamantyl)-malonamic acid ethyl ester gave a-amino-1- -adama:ntylacetic acid (XVIII)
