In the present paper parallel submanifolds and focal points of a given submanifold with flat normal bundle are discussed provided that the ambient space has constant sectional curvature. We present shape operators of parallel submanifolds with respect to arbitrary normal vectors. Furthermore, we prove that the focal points of a submanifold with flat normal bundle form totally geodesic hypersurfaces in the normal submanifolds.

intends maximizing the amplitude of displacement at the focalpoint while minimizing the effect of side lobes. The primary advantage of the proposed design procedure is that it provides a systematic methodology for PAUT probes optimisation. This offers
This article briefly presents some of theWissenschaftsrat's recent activities which were (and are) particularly designed to exert an influence on the structural development of German universities,Fachhochschulen and research institutes: Evaluations of research institutes, recommendations on structural changes in the higher education system, and statistics concerning the age structure of professors and the employment prospects for young academics. The focal point will be the question: What has been the impact of the reports and recommendations on higher education and research policies?
The paper analyses Hungary's competitiveness in international comparison by focusing on the supply-side factors determining competitiveness. Although it attaches outstanding importance to the business-friendly general economic environment mainly in terms of the transition to the market economy and attracting foreign direct investments, the interrelationship among labour productivity, labour costs and nominal and real exchange rates are in its focal point. Its main conclusion is that it is labour productivity which determines international competitiveness in the long run. However, appropriate economic-policy measures are required to prevent the erosion of relative international competitiveness by increasing labour costs and the real appreciation of the national currency.
I use “prospects” to connote the continuing subversion of the environment. “Expectations” refer to what I think Statistics should be making of itself in the era of global change science. I develop thoughts on these in three main sections. In the first, I recount up-to-date information about global warming. This topic is intriguing to me, since global warming is potentially the most subversive environmental process, appears least preventable, and as such, most deserving to be a focal point in ecological study scenarios. In the second section, I discuss briefly the ecological agenda and the implications therein for definition of the sampling environment. The third and last large section explains how I think of what should constitute an applicable statistical dialect for users in global change science. I detail the basic principles, enumerate choices, and deal with other bare necessities upon which such a Statistics should be founded.
The focal point of the paper is the interpretation of the name and the figure of Libitina, the Roman goddess of the graveyard. It deals with the arguments of her Etruscan origin and finds them lacking in convincing evidence. Instead, the paper is undertaking to establish Libitina's ancient association with the Latin stem lib- (lub-) is right. The assertion that she belongs to a series of figures formed from the same Latin stem, as Lubia / Lubentia / Lubentina, proves to be correct and the creation of such series is to be seen as a usual procedure for 'Sondergötter'. Her secondary identification with Venus is not a misunderstanding, on the contrary, it is based on the general idea of humanity, that love and death are organically connected with each other. This is corroborated by many ancient and modern examples.
The Laboratory of the Government Chemist (LGC) is a focal point for the production, analysis and certification of reference
materials. Within the field of thermal analysis the LGC is concerned with the development of purity standards and materials
certified for enthalpy of fusion and melting point. For some time the LGC has been concerned with the significant differences
in purity data which can be produced by the different manufactures' differential scanning calorimeters. This paper will highlight
the initiatives the LGC is undertaking in overcoming this uncertainty in purity measurements through the use of certified
The one hundredth anniversary of the end of World War I and the subsequent peace negotiations will inevitably become a historical focal point. Accordingly, this article will deal with American involvement in Europe, but especially in Hungarian affairs with regards to the private realm rather than the official spectrum. American participation always bordered official yet unofficial conduct, which is even truer for the successor countries in Central Europe. A few Americans visited Hungary during the Peace Conference in various capacities. Although their official work has been to a large degree uncovered by historians, their private work still remains elusive. Hence, the diary of such an American officer will shed light on various interesting angles of American thinking of the era and the relationship between American representatives and various Hungarians of the day. The article will introduce Charles Moorfield Storey’s journal, a significant part of which was written while he was in Hungary in the first few weeks of 1919. Storey was a member of the famous Coolidge Mission, whose headquarters was in Vienna. From here Americans set out to visit and gather information on the various countries in their purview, Hungary among them. Based upon the diary entries, one can learn about daily work of the Americans at the Paris Peace Conference, the Coolidge Mission, and Storey’s experience in Hungary shortly after the conclusion of the war.
1889 the Weimar Theatre intendant invited Richard Strauss to join the staff of the Hofoper as second Kapellmeister. Weimar was a tempting proposition for the recent convert to the New German School. The Lisztian effect was soon make itself felt in Strauss symphonic works. His Liszt studies were crucial to his musical development. Weimar offered him the opportunitiy to translate theory into practice. Liszt's orchestral music had been largely shunned and despised in the great tratidional performing centres of Europe during his life-time. He occupied a more commanding position in Munich's concert life (1894–99). In the Akademie season 1894–95 Strauss conducted in Berlin. He actively supported Liszt's music (Mephisto-Waltz, Die Ideale, Mazeppa, 2nd Piano Concerto). It was undoubtedly Liszt's perception of the complementary nature of form and expression that was attractive to Strauss. Form and content apart, Strauss's was also intrigued by Liszt's unconventional harmonic procedures and, by his indiviual style of orchestration. In 1898 Strauss moved to Berlin as erster königliche Kapellmeister at the Staatsoper. His modern concerts (1910–1903) featured Liszt symphonic poems. His admiration for Liszt's music and its seminal impact upon his own work is beyound doubt. His devotion to the Lisztian cause is transparent and was enduring: witness his tireless and activities on behalf of the Liszt Gesamtausgabe. Strauss kept Liszt's orchestral works in the public domain by making them the focal point of his permanent repertoire (Graner Messe, Mazeppa, Mephisto Walltz, Les Préludes, Orpheus, Faustsinfonie etc.). Liszt's music was a life-long obsession for Strauss.
Tanulmányomban a „hosszú” ’68-as diáklázadások történelmi előzményeit, fő
történéseit, társadalmi hatásait és utóéletét mutatom be. Emellett tárgyalom
azokat az elméleti problematikákat, melyeket mindezek felvetnek. Fő tézisem: a
diáklázadások céljai komplexek voltak, számos emancipatorikus mozzanatot
tartalmaztak, de a célok középpontjában a szabadság-egyenlőség-testvériség
hármasából elsősorban a szabadság értéke emelkedett ki. Ez kapóra jött a ’70-es
évek neoliberális fordulatát levezénylő társadalmi aktorok számára, melyek
domesztikálták és a maguk javára használták fel a ’68-as ifjúság szabadságvágyát
és ezzel összefüggő államellenességét. Bemutatom továbbá, hogy a lázadásoknak
milyen azonos és különböző társadalmi előzményei, vonásai és hatásai voltak
Nyugaton és Magyarországon. Elemzem azt is, hogy a ’68-as eszmei, etikai és
szellemi hagyaték mindazonáltal igen gazdag és sokszínű, amelyekből a lázadó
ifjak újabb és újabb generációi mind a mai napig táplálkozhatnak.
