Arp 206 is a nearby (7.8 Mpc), relatively large (7′.5 x 2′.0), and bright ( = 11.07) interacting system comprising unequal members: NGC 3432 and UGC 5983. A third anonymous galaxy, “Arp 206c”, is visible in the field, (see Figure la) Vorontsov-Velyaminov (1959) included the NGC 3432-UGC 5983 pair in his Atlas and Catalogue of Interacting Galaxies (VV-11). On the other hand Arp (1966) interpreted the system as a galaxy with material ejected from the nucleus (Arp 206).Bertola (1966, 1968, and priv. comm.) obtained long-slit spectra of the largest galaxy of the pair, NGC 3432. This showed strong non-circular motions that could be interpreted as an explosion in its nucleus. This work is in line with a similar study of another system, Arp 205 (Bertola et al. 1983, Noreau and Kronberg 1986, 1987). In this first case it was found that the non-circular radial velocities were caused by the ‘re-entry’ of galactic material torn away by the interacting system.

This article is about Russian Empress Catherine the Great, her relations with her son Paul and grandson Alexander and role that she played in their upbringings. When Paul, Catherine’s only legal son was born, he was taken from her by Empress Elizabeth. That – and the fact, that Paul blamed Catherine for the death of his father – resulted in the fact, that they never develops proper, familial relation. On the other hand, Catherine was very active and affectionate grandmother, primarily for her oldest grandson, Alexander. She wanted to raise him to become ideal enlightened monarch. She took care of his education and even wrote fairy tales for him herself. Paul hated mother with bitter passion. Alexander loved her, but her influence shaped also his negative features. Catherine had undoubtedly great impact on both her son’s and grandson’s lives, but in the first case – impact was definitely negative and in second case – only arguably positive.

Resumo No final dos anos sessenta, ocorreu uma eclosão do cinema folclórico-histórico na Argentina e em Cuba. No primeiro caso, isso se deu principalmente devido ao interesse da ditadura de Onganía em utilizar os mitos fundadores da nação como uma metáfora legitimadora do regime. Contrários a essa tendência, o Grupo Cine Liberación elaborou representações desses relatos que buscavam adaptá-los à contingência, especialmente nos filmes La hora de los hornos (1968) e Los hijos del Fierro (1976). Em Cuba, o centenário da Guerra Grande (1868-1878) e a maior rigidez ideológica em matéria cultural durante o Quinquênio Gris (1971-1976) levaram a que se fomentasse a produção de um cinema histórico que representava a Revolução de 1959 como o produto de um século de luta. Os cineastas cubanos e Cine Liberación coincidiram em sua busca por renovar a forma de representação cinematográfica da História, enquanto o cinema comercial argentino apostou em adaptações distantes desse revisionismo. Résumé À la fin des années soixante s’est produit en Argentine et Cuba une éclosion du cinéma folklorique-historique. Dans le premier cas, ceci est dû principalement à l’intérêt de la dictature d’Onganía à se servir des mythes fondateurs de la nation avec l’objectif d’élaborer des métaphores légitimatrices du régime. Face à cela, Grupo Cine Liberación a élaboré des représentations de ces récits tout en cherchant à les adapter à la contingence, notamment dans les films L’heure des brasiers (1968) et Les fils de Fierro (1976). À Cuba le centenaire de la Guerre des dix ans (1968-1878) ainsi qu’une plus grande rigidité idéologique dans le domaine culturel pendant le Quinquennat Gris (1971-1976), ont conduit à l’encouragement de la production d’un cinéma historique où la révolution de 1959 est représentée comme la conclusion d’un siècle de lutte. Les cinéastes cubains et Cine Liberación ont partagé leur intérêt de renouveler les représentations cinématographiques de l’Histoire, tandis que le cinéma commercial argentin a misé sur des adaptations éloignées du révisionnisme.Abstract At the end of the sixties, there was a growth of historical-folkloric cinema in Argentina and Cuba. In the first case, it happened mainly because of the interest of the Onganía’s dictatorship in making use of the nation’s founding myths to develop metaphors to legitimize this regime. On the other hand, Grupo Cine Liberación elaborated representations of these narratives trying to adapt them to the contingency, especially in the movies The hour of the furnaces (1968) and Los hijos del Fierro (1976). In Cuba, the centenary of the War of ten years (1868-1878), as well as an increase of ideological rigidity in the cultural domain during the Grey Quinquennium (1971-1976), encouraged the production of a historical cinema where the revolution of 1959 has been represented as the conclusion of a century of struggle. Cuban filmmakers and Cine Liberación shared their interest in renewing the filmic representations of History, whereas the Argentinean commercial cinema supported adaptations far from this revisionism.Palavras-chave Cinema histórico, legitimação, mitos nacionais Mots-clés Cinéma historique, légitimation, mythes nationauxKeywords Historical cinema, legitimization, national myths

Cognitive therapy, as conducted by Aaron T. Beck and his associates, is known for effectively teaching clients to modify the kinds of dysfunctional thinking processes that are associated with depression and a number of other disorders. On the other hand, cognitive therapy has developed a reputation for paying too little attention to emotionality and its expression thereof as part of treatment. In spite of this popular viewpoint, it is argued here that cognitive therapy is very much concerned with the appropriate experiencing of affect. Two brief case illustrations are presented that highlight the role of emotion enhancement as an important, congruent component of cognitive therapy. The first case demonstrates the facilitation of positive affect in therapy, while the second case example suggests that the augmentation of negative affect may also be appropriate during the course of cognitive therapy.

The reduction of a binary sulfate mixture cannot be predicted from the behavior of the individual components. Thus, while CuSO4 is reduced to Cu at 400 °C and NiSO4 is reduced to Ni3S2, the sulfate mixture yields Cu, Ni3S2, and Cu2S. Also while FeSO4 is completely stable in H2 at 400 °C, (Cu,Fe) SO4 yields Cu and Cu5FeS4. The formation of Cu2S in the first case and Cu5FeS4 in the second was unexpected. On the other hand, (Cu,Mn)SO4 is stable in H2 up to 550 °C although pure CuSO4 is completely reduced at 400 °C. CoSO4 also interferes when reduced in presence of CuSO4, while Na2SO4, MgSO4, Al2(SO4)3, ZnSO4, CdSO4 do not interfere within limited temperature range. Of these only Na2SO4 forms a complex sulfate with CuSO4. No Cu2SO4 was identified when CuSO4 was reduced in presence of other sulfates although it is an intermediate product during the reduction of pure CuSO4.

AbstractThe analysis of radial velocities in the spectra of HD 151932 and HD 152233, performed for the optical lines of interstellar CH and CH+ molecules on one hand, and for the diffuse bands 4964 and 6196 Å on the other hand, suggests that the carrier of the former DIB is spatially related to CH, while the carrier of the latter - to CH+. A further analysis, based on the sample of 106 reddened OB stars, partly confirms this suggestion, showing that the CH column density correlates indeed much better with the equivalent width of the 4964 DIB than with that of the 6196 DIB.

<p><strong>Resumo: </strong>Este trabalho propõe-se a apresentar a problemática que envolve a disciplina de Filosofia da Educação no Brasil, abordando primeiramente, de um lado, como a Filosofia em si mesma chega em terras brasileiras como parte do programa colonizador português e, de outro lado, como a Educação foi tratada em nosso país desde os seus primórdios, cujos elementos problemáticos são cruzados com aqueles observados no primeiro caso. Nesse sentido, entende-se a Filosofia da Educação como um campo conflituoso em razão dessas forças que atravessam o seu campo de atuação. Por conseguinte, são estabelecidas algumas medidas de enfrentamento dessa situação, como sugestão do estudo, apontando para a necessidade de a disciplina acompanhar o seu próprio trabalho com a atenção merecida, no sentido de desnudar e minimizar as dificuldades de sua prática pedagógica e enquanto proposta disciplinar oferecida no contexto de formação de professores.</p><p><strong>Palavras-chave: </strong>Filosofia da Educação; Filosofia e Educação; Formação de professores.</p><p><strong>Abstract: </strong>This study aims to present a problem involving the discipline of Philosophy of Education in Brazil, first addressing, in the one hand, how the philosophy itself arrives in Brazilian lands as part of the Portuguese colonizer program, and on the other hand, how Education was treated in our country since its origin, whose problematic elements are crossed with those observed in the first case.

The latest book on metamorphism, Dr. V. Grubenmann's Kristallinen Schiefer, still leaves it an open question what a metamorphic rock is. Generally speaking there is no doubt about the matter; every geologist has a more or less precise idea of what he means by the term, but no one has yet been able to propound a definition which is perfectly satisfactory, and which will enable one to distinguish a metamorphic rock from all other kinds and at the same time convey an expression of the characteristic peculiarities inherent in such a rock. The need of a definition is very necessary. The want of it has led Dr. Grubenmann to include some rocks among the crystalline schists which one ordinarily would not refer to that class, and on the other hand there are some rocks frequently referred to that class which are not included. In the first case, the masses of emery form the twelfth group of Dr. Grubenmann's classification, yet the analysis of the Naxos emery, which reveals traces of boric oxide (1.15 per cent. in one case) would seem to place these lenses among the ore-bodies deposited by pneumatolitic action.

Recently, a number of possible young globular clusters (GCs) have been found in some merging/interacting galaxies or starburst galaxies. On the other hand, it is well known that GCs are numerous in giant elliptical galaxies many of which are thought to be formed via major merger of galaxies. These facts lead us to a thought that the formation process of GCs could accompany galaxy – galaxy interaction followed by starburst. The archetypical starburst galaxy M82 is an ideal target to study the relation between galaxy interaction, starburst, and GC formation.

Many carefully selected samples of interacting galaxies have been observed expensively in attempts to clarify whether interaction produces activity in galaxies. Because the sample members represent a wide range of encounter parameters and times, one can then study whether there are correlations between observable encounter features and, for example, Seyfert activity. On the other hand, in theoretical studies, simulations typically deal with either time-consuming detailed modelling of single galaxy pairs or tracing a few model encounters over time. We are extending the observational survey approach by combining it with a simulation survey.

The Bulge carbon stars have been a mystery since their discovery by Azzopardi et al. (1991), because they are about too faint to be regarded as genuine AGB stars, if located inside the metal-rich Bulge . Part of the mystery can be solved if these carbon stars are related to the Sagittarius dwarf galaxy . They are in that case not old and metal-rich, but young, ∼0.1 Gyr, with SMC-like metallicity (Ng 1998).The σRV = 113 ± 14 km s−1 (Tyson & Rich 1991) radial velocity dispersion of the stars appears to be consistent with Bulge membership. On the other hand, a similar velocity dispersion could be the result from an induced star formation event when the SDG crosses the galactic midplane. It is suggested that the carbon stars are tracers of such an event and that they therefore are located at distances related to the SDG. However, the majority of the carbon stars are not member of the SDG, nor are they similar to the C-stars which are member of the SDG.The radial velocities can be used to determine a possible membership to the SDG. However, they do not give information about the distance of the stars. In particular, if the stars are located at a distance comparable to the SDG. This implies that only the period-luminosity relation (Groenewegen & Whitelock 1996) can be used to distinguish unambiguously if the carbon stars are located at Bulge-like or SDG-like distances. Thus far only carbon stars with reliable periods have been identified at a SDG related distance (Ng & Schultheis 1997; Whitelock 1998).
