HYDRODYNAMICS OF THREE PHASE FLUID DISPERSE COLUMNS
In industry, the separation of various gases from mixtures is often necessary. In such
procedures absorbent liquids are used to drive out undesirable components, either in con-
tinuous or gradual phase contact installations. The same operational units are adequate
for the separation of two or multiple component mixtures, using rectification procedures.
The contact of liquid and gas (vapour) may be made very efficient using the so-called
three phase fluid disperse systems the features of which will be discussed in the present
paper
THREE-PHASE, FLUID DISPERSE SYSTEMS FOR GAS/LIQUID COUNTERCURRENT CONTACTING
There are numerous unit operations in the field of chemical engineering (such as
absorption, desorption, scrubbing, distillation, etc.) which can only be carried out if gas
(vapour)/liquid contacting is applied. The main dimension of the operating equipment depends
on the diffusion rate. The application of three-phase, fluid disperse systems yields much better
results than the use of traditional fixed bed columns

Oakeshott és a XX. századi antiracionalizmus = Oakeshott and the antirationalism in the 20th century
Oakeshott Ă©letműve a szabadság Ă©s a hagyomány, a szkepticizmus Ă©s a nyugati hagyományba vetett bizalom, a konzervatĂv gondolkodás Ă©s a jelen Ă©lvezete összekapcsolásával ĂrhatĂł le. Nem akart rendet minden áron. El tudta viselni a zűrzavart, Ă©s Ăşgy gondolta a politikai gondolkodás egyik feladata az, hogy kĂ©pessĂ© tegye az embereket a kaotikus világ elfogadására Ă©s Ă©lvezetĂ©re. A kĂ©rdĂ©s Oakeshott kapcsolata a modernitáshoz Ă©s a posztmodernhez. Noha láthatĂłak közös elemek a posztmodern Ă©s a premodern gondolkodásban, nyilvánvalĂł eltĂ©rĂ©sek is vannak. Az egyik bizonyosan, legalábbis Oakeshott esetĂ©ben, a törvĂ©ny uralma. És az autoritás szerepe. A politikai modernizmus igyekszik átalakĂtani a politikát manager tudománnyá, amely folytonosan harcolna a lĂ©tezĹ‘vel, mert tökĂ©letlen, Ă©s egy utĂłpikus, harmonikus vĂ©gállapotra törekszik a nĂ©p átnevelĂ©se vagy manipulálása rĂ©vĂ©n. Felismerte a modernitás ellentmondásait, de el akarta a kerĂĽlni a modernitás utĂłpikus kĂsĂ©rtĂ©sĂ©t is (törtĂ©nelem vĂ©ge). A modernitás ellentĂ©tekbĹ‘l áll, Ă©s ezek egyensĂşlyozzák ki. A modernista hiba, ha valaki az egyik szĂ©lsĹ‘sĂ©get választja. A feladat az ellentĂ©tek megĹ‘rzĂ©se Ă©s nem a megoldása. A conditio humana lĂ©nyege az ellentĂ©tek egysĂ©ge. A modern gondolkodás megprĂłbálta az ellentĂ©tek e bonyolult világát leegyszerűsĂteni egy egyszerű alapelvre, egyetlen magyarázatra. E paradox felismerĂ©se határozza meg a konzervatĂv gondolkodĂłt. A politika dilemmái vĂ©gsĹ‘ soron a conditio humana dilemmái. MindkettĹ‘ örök. | Oakeshott’s work is a negotiation of freedom and tradition; “skepticism” and confidence in the resources of the Western tradition; conservatism and the celebration of the present. He were never engaged in an irritable search for order. He could accept confusion and he thought that one task of political and moral thinking is to make the people able and enjoy the chaotic world as it is. One aspect of this issue is his relation to modernism and postmodernism. Whilst one may see common points in the pre-modern and post-modern thinking, there are obvious differences, as well. One of them, at least in case of Oakeshott is rule of law and the role of authority. Modernism in politics means the continuous effort to transform politics into a managerial science that struggles against present as imperfect, and aiming an utopical, harmonious end state by means of re-education or managerial manipulation of people, based on hedonistic calculus. He realized the ambivalences within modernity, but he also was keen to avoid the modernist seduction of utopical hope. Modernity is divided yet balanced. Modernist political thought has tried to reduce this incongruous complex in modern order to a single principle, a single explanation. The core of human condition is a fusion of opposites. To realize this paradox of order defines the conservative thinker. The dilemmas of politics are ultimately dilemmas of the human condition
Thomas Molnar and the Conservatives in the US
Thomas Molnar, a Hungarian Catholic emigé, was a well known figure in the American conservative movement. In spite of the warm welcome of his works criticizing leftism, he stayed at the margin of this movement. Molnar never accepted the fusionism, he was critical concerning free market, and he openly refused many presuppositions of the Anglo-Saxon liberal democracy. He transported elements of the French Catholic conservative thinking into the US like the attraction to monarchical authority and hierarchy. For him the idea of time-tested tradition was hardly important, when he used the notion of tradition he referd to its perennialist meaning. The paper argues that his criticism of (political) modernity was form by the Pascendi dominici gregis
Az ukrán-magyar határvidék társadalomföldrajzi vizsgálatai, kapcsolatrendszer és együttműködés a két ország határmenti térségében = Social geographical study of the population of the Ukranian and Hungarian borderland areas and study of crossborder cooperation
A következĹ‘k befolyásolták a határ kĂ©t oldalán lĂ©vĹ‘ tĂ©rsĂ©gek közötti kapcsolatokat: 1.politikai helyzet 2.a határátkelĹ‘k, ellenĹ‘rzĹ‘pontok meglĂ©te 3.rokoni kapcsolatok (a legális határon átnyĂşlĂł kapcsolatrendszert erĹ‘sĂtette az intenzĂvebb rokonsági kapcsolatrendszer) 4.gazdasági helyzet (az illegális határon átnyĂşlĂł kapcsolatokat is befolyásolja), árak közötti kĂĽlönbsĂ©gek 5.a határvidĂ©k telepĂĽlĂ©shálĂłzata (rurális vagy városi tĂ©rsĂ©g), ez utĂłbbi esetĂ©ben intenzĂvebb a kapcsolatrendszer. A határvidĂ©kek esetĂ©ben az alábbi problĂ©mákra figyelhettĂĽnk fel: 1.Politikai konfliktus, amelyek rendszerint a meglĂ©vĹ‘ államok vagy pártok között feszĂĽlnek 2.Gazdasági gondok, mint a rurális tĂ©rsĂ©gek elszigeteltsĂ©ge, az elszegĂ©nyedĂ©s, stb. 3.Demográfiai problĂ©ma, elöregedĂ©s; valamint szelektĂv elvándorlás, ha a körĂĽlmĂ©nyek kedvezĹ‘tlenek. Itt azt is meg kell jegyezni, hogy a termĂ©szetes szaporodás majdnem egĂ©sz EurĂłpában nagyon alacsony, ill. helyenkĂ©nt negatĂv, de a vizsgált tĂ©rsĂ©gekben több helyen az elvándorlási tĂ©nyezĹ‘ meghatározĂł mĂ©rtĂ©kben rontja, illetve fokozza ezt a helyzetet. 4.Társadalmi Ă©s etikai problĂ©mák, Ă©s etnikai konfliktus; az elszegĂ©nyedettsĂ©g, a faji, vallási elĹ‘ĂtĂ©letessĂ©g, stb. | It was found that the main factors affecting the border area: 1. Permeability of the frontier depends on the political situation, presence of checkpoints on the border (difficulty or perceived difficulty in crossing, militarization, etc.). 2. Legal border crossing was more frequent when there were close familial relationships between people living on two sides of the border. 3. The intensity of illegal border crossing depended on the economic and political situation. Where there is a big difference in the price of certain goods between the two countries some inhabitants try to exploit this. 4. The findings suggest another main factor of border life and contact is whether the area is rural or urban. It appeared to be easier to build cross border relationships in urban areas. The borderlands present a range of different problems, of variable seriousness: 1. political problems, including conflict between governments, ethno-national groups and political parties. 2. economic problems, like rural area depression, deindustrialization, geographical isolation, etc. 3. demographic problems, mainly of population decline; selective emigration 4. social and ethnical problems, like deprivation, racial prejudice, etc
METHOD FOR THE DETERMINATION OF HEAT AND MASS TRANSFER COEFFICIENTS IN THE CASE OF THROUGH-CIRCULATION DRYING OF LUCERNE*
The present paper deals with the determination method of the drying characteristics of
lucerne. The determination principle of heat and mass transfer coefficients required for modelling
the through-circulation drying process of a lucerne bed, on the basis of drying experiments, the
calculation method of the so-called specific phase contact surfaces will be described here, in the
knowledge of the preceding notions as well as of the volumetric transport coefficients. The
transport characteristics, measured according to the above-mentioned principle and further the
comparison of the measured and numerically calculated results of the drying process of an
experimental lucerne bed will be discussed, too
