The  natural regeneration of American oak and pedunculate oak under cover occurs  regularly in the Aelmoeseneie forest. Nevertheless, these seedlings tend to  establish very difficultly. They often die off after one year. In order to  survive, the crown cover has to be strongly opened after the first year.      One year old seedlings of American oak, however, grow slightly better under  cover than under partial freestand. The seedlings of pedunculate oak, on the  other hand, hardly react on the different light conditions.     The American oak seeds are of good quality. A considerable amount is eaten  by the birds. The seeds of pedunculate oak are of a minor quality; an  important number is eaten by the worms. The growth of the seedlings in the  Aelmoeseneie forest does not always correspond to the growth on other sites.

Abstract Guigo II is commonly known and praised among specialists of Western mysticism for his Scala claustralium, a work that presents a spiritual program for cloistered monks. His Meditations, on the other hand, have usually been relegated to the margin of attention. The First Meditation, in particular, is generally regarded as a minor piece. The paper argues, however, that a new approach can make better sense of the First Meditation, while also enabling us to recognize its specific function and value. Seen from this new perspective, Guigo’s purpose with the text is to train and exercise his readers’ minds according to the spiritual program laid out in the Scala. The paper shows that the First Meditation realizes that goal, surprisingly, by having the same essential features that Umberto Eco found in the ‘open works’ of the Western avant-garde.

One of the insects that feeds on pedunculate oak acorns and reduces its seed yield is Curculio elephas Gyll. The study of Curculio elephas Gyll is necessary because of the severe damages caused by this insect and also owing to its insufficiently investigated biology. The research was conducted in the common oak seed orchard at Banov Brod, forest estate ?Sremska Mitrovica?, and in the entomological laboratory. The adults emerge from the soil chambers from mid July till the beginning of September. The presence of adults, as determined by crown fogging, ranged from the end of July till the beginning of September with the highest number in mid August. After emerging from the soil, females are already fertile with the developed eggs in the ovaries. They start egg laying after 1 to 8 days and they lay from one to seven eggs per day. Egg laying period lasts from 7 to 20 days. Fertility of C. elephas females ranges from 5 to 40 eggs, while their fecundity ranges from 19 to 45 eggs. At the end of the larval stage, larvae bore into the soil and stay there from one to three years. The species hibernates only in the larval stage. C. elephas has a one-year life cycle, while a minor part of the population has a two or three-year life cycle.

In order to evaluate the factor structure of the Emotions Profile Index (EPI) 217 first-year students accommodated in the school?s dormitory were examined. The data was analyzed with Beelzebub algorithm for comparative confirmative and exploratory component analysis. The results show that the empirical structure of EPI can be related with 4 bipolar factor structure proposed in the scoring key, although the relation is far from indubitable. The structure of hypothetical dimension Distrustful vs. Trustful has a solid empirical foundation, correlations between orthoblique and hypothetical factors of theoretical dimensions Gregarious vs. Depressed and Timid vs. Aggressive are acceptable while, on the other hand, the structure of the hypothetical dimension Controlled vs. Dyscontrolled requires revising, not only because the Adventurous trait is used to describe both of their poles but for numerous other reasons. The paper suggests a few ways of improving the characteristics of the test.

The paper summarizes the results of 15-year natural regeneration for beech of five plots with different densities situated in the Western Carpathians Mts. Three of the plots were subjected to differently intensive shelterwood cuttings (plots L, M, H), one plot was clear-cut (CC), and one was left without intervention – as a control (C). The number of one-year-old seedlings decreased proportionally with increasing cutting intensity. The ANOVA results document a significant influence of cutting intensity on the abundance of both one-year-old and older seedlings. The abundance of beech seedlings was initially increasing with increasing cutting intensity, and, having reached the peak on plot M (medium intensity), there followed a decrease in the seedling abundance. Lower numbers of beech seedlings on plots subjected to less intensive cutting (C, L) result from less favourable growth conditions in comparison with plot M. On the other hand, cutting of higher intensity (H, CC) resulted in lower numbers of fructifying parent trees. The medium cut intervention having provided the plot M with stocking of 0.5 (50% of the stand) resulted in a lower number of seed resources (limiting factor for natural regeneration). However, for the other factor – seedling establishment (survival and recruitment) this plot (M) represents an ecological optimum in beech regeneration in the given conditions.

This chapter presents a sermon by Maurice N. Eisendrath, delivered on the third Rosh Hashanah of the war. The situation of Canadian rabbis was precariously positioned between those of American preachers to the south and British preachers to the east. Canada, as part of the British Commonwealth, had long been part of the war effort, so the debate over whether or not to enter the war was not an issue, as it still was for colleagues in the United States. On the other hand, Canada was not directly affected by the war as was Britain, where one year earlier London had suffered a sustained air attack unprecedented in its devastation (a situation that certainly affected the mood in Toronto on the previous Rosh Hashanah, as the preacher reminds his listeners). Now, although the battles on the recently opened Eastern Front were of almost unimaginable ferocity, to many Canadians the war seemed distant; life at home seemed almost normal, as it did to many in the United States. This was precisely the mindset that Eisendrath set out to censure.

The method adopted by Mr. Fearn in dealing with the above subject in the February number of the Journal is open to many serious objections. To begin with, it is at best approximate and as Mr. Farren points out in his article in the March number, Mr. Fearn's approximation, although near enough for displacements, give on double differentiation less close approximation for acceleration. And for less regular motions than in the case under discussion the approximation to the acceleration by Mr. Fearn's method might be comparatively poor.The greatest objection which the writer has to Mr. Fearn's method is that it is far too intricate and cumbersome. It unnecessarily involves mathematics of a high order when the problem can be solved by means within the compass of any first year student of engineering.Mr. Farren's method, on the other hand, is of extreme simplicity and as a graphical method could hardly be improved upon. But there is a very simple-analytical solution and one moreover of the familiar type for the ordinary nonarticulated case.


I shall not attempt to sum up the conclusions of the day’s discussion, because what conclusions we have come to (and quite a number of points have come out clearly) are rather involved and technical, and I should not at this time go into details; on many major points we have not reached any definite conclusions. There remains much more interesting work to be done; but I should like to comment on a few facts that have come out: In the first place, one is impressed by the amount of information which has been produced in the course of a year. Most of the problems which we have discussed during the day did not exist even as questions one year ago, and it is quite impressive what has been done in this time. We should not complain that all the answers are not available today. Of course, the existence of parity violation is now established beyond any doubt, and an extremely simple feature seems to emerge, though still subject to exact confirmation, in the behaviour of the polarizations, which seems to select fairly heavily between the possible interactions. On the other hand, we have no clear picture yet of the recoil data which might be capable of tying down the possible interactions very closely, or alternatively of showing us that there is something basically wrong with the whole present approach. We should not discount that possibility at the present stage.

The Study of Religion (Shūkyō-gaku) is an early text from a one-year course, 1913-1914, which Nishida Kitarō imparted only once in his academic career. In this text, apart from references to mystics and to early and medieval Christian thinkers, Nishida tries to point out the basic elements of Eastern and Western religions through the writings of xviii-xxth century authors, among them participants in the Gifford Lectures, the Bampton Lectures and Hibbert Lectures. On the other hand, Nishida tries to find the corresponding characteristics of religion in Zen and True Pure Land Buddhism. In short, Nishida’s approach to a philosophy of religion gives us an overview of the problems concerning a Buddhist-Christian dialogue.

Strain A/J mice made secondary indirect plaque-forming cell (PFC) responses to azobenzenearsonate (ABA) conjugates of giant keyhole limpet hemocyanin (KLH), a thymic-dependent antigen, but not to conjugates of Ficoll, a T-independent antigen. ABA-Ficoll was also unable to elicit a response in animals primed with ABA-KLH, which have an expanded anti-ABA memory cell pool. On the other hand, ABA-Ficoll rendered mice unresponsive to ABA-KLH when administered before priming or boosting with the T-dependent immunogen. Hence, the T-independent antigen was able to tolerize but unable to trigger B-memory cells responsive to the T-dependent antigen. A/J mice immunized with dinitrophenyl conjugates of Ficoll or bovine IgG (BGG) made vigorous IgM and IgG PFC responses. PFC responses to ABA-KLH and 2,4-dinitrophenyl (DNP)-BGG were abrogated by depleting mice of C3 with cobra venom factor, whereas the IgM and IgG PFC responses to DNP-Ficoll were unaffected. B lymphocytes were fractionated on the basis of receptors for C3 and the subpopulations were assayed for in vitro PFC responses to DNP-Ficoll. Very little response was obtained from complement receptor lymphocyte [CRL(+)] B cells, whereas CRL(-) cells were more responsive than unfractionated B cells. Both populations responded to a polyclonal B-cell mitogen (lipopolysaccharide). On the other hand, the in vitro PFC response to a T-dependent antigen (sheep erythrocytes) correlated with the presence of CRL(+) B cells in the cultures. However, a minor component of this response, sensitive to anti-Thy-1 serum, was made by CRL(-) B cells, indicating the existence of subpopulations of T-dependent B cells with different signalling requirements. The results suggest that most B cells responsive to T-dependent antigens possess receptors for C3 and that C3 plays an obligatory role in the response of these cells. A distinct subpopulation of B cells which lack C3 receptors respond to T-independent antigens. The precursors of PFC for the ABA epitope reside largely or exclusively in the CRL(+) compartment in A/J mice, whereas precursors for the DNP determinant are found in both compartments.

La autotraducción es un fenómeno que siempre ha estado presente, sobre todo, en aquellos sistemas socioculturales de gran riqueza lingüística y cultural. Este es el caso del sistema peninsular, donde cada vez más autores bilingües deciden escribir sus obras en una lengua minoritaria y, después, autotraducirlas al español. En este trabajo, se toma como objeto de análisis la poesía autotraducida del asturiano al español de Xuan Bello. Así, se observará si la autotraducción permite a este autor traductor, por un lado, trasladar sus reivindicaciones culturales a otro sistema ajeno al asturiano; y, por otro lado, definir su identidad individual.Palabras clave: autotraducción, poesía, asturiano, español, cultura, identidad.Self-translation is a phenomenon which has always been present, most of all in those sociocultural systems characterized by both their linguistic and cultural richness. One of those is the Spanish peninsular system where more and more bilingual authors tend to write their works in a minor language and subsequently translate them into Spanish. The aim of this paper is to research Xuan Bello’s self-translated poetry from Asturian into Spanish. That way it will be considered whether selftranslation helps this author-translator: on the one hand, to transfer his cultural demands; on the other hand, to define his individual identity.Keywords: self-translation, poetry, Asturian, Spanish, culture, identity.
