scholarly journals The principal magnetic susceptibilities of neodymium sulphate octahydrate at low temperatures

The magnetic and other related properties of neodymium sulphate have been the subject of numerous investigations in recent years, but there is still a remarkable conflict of evidence on all the essential points. The two available determinations of the susceptibility of the powdered salt at low temperatures, those of Gorter and de Haas (1931) from 290 to 14° K and of Selwood (1933) from 343 to 83° K both fit the expression X ( T + 45) = constant over the range of temperature common to both, but the constants are not the same and the susceptibilities at room temperature differ by 11%. The fact that the two sets of results can be converted the one into the other by multiplying throughout by a constant factor suggested that the difference in the observed susceptibilities was due to some error of calibration. It could, however, also be due to the different purity of the samples examined though the explanation of the occurrence of the constant factor is then by no means obvious. From their analysis of the absorption spectrum of crystals of neodymium sulphate octahydrate Spedding and others (1937) conclude that the crystalline field around the Nd+++ ion is predominantly cubic in character since they find three energy levels at 0, 77 and 260 cm. -1 .* Calculations of the susceptibility from these levels reproduce Selwood’s value at room temperature but give no agreement with the observations-at other temperatures. On the other hand, Penney and Schlapp (1932) have shown that Gorter and de Haas’s results fit well on the curve calculated for a crystalline field of cubic symmetry and such a strength that the resultant three levels lie at 0, 238 and 834 cm. -1 , an overall spacing almost three times as great as Spedding’s.

It is increasingly realized that hypnosis may be seen from an interpersonal point of view, meaning that it forms part of the relationship between the hypnotist and the subject. From this premise it follows that what goes on in the relationship prior to hypnosis probably has an influence on the hypnosis. Certain of these prior occurences can then be seen as waking suggestionns (however implicitly given) that the subject should behave in a certain way with regard to the subsequent hypnosis. A study was conducted to test the hypothesis that waking suggestions regarding post-hypnotic amnesia are effective. Eighteen female subjects were randomly divided into two groups. The groups listened to a tape-recorded talk on hypnosis in which for the one group amnesia for the subsequent hypnotic experience and for the other group no such amnesia was suggested. Thereafter the Stanford Hypnotic Susceptibility Scale was administered to all subjects. Only the interrogation part of the amnesia item of the scale was administered. The subjects to whom post-hypnotic amnesia was suggested tended to score lower on the amnesia item than the other subjects, as was expected, but the difference between the mean amnesia scores of the two groups was not significant.

What is the source and the effect of the acting subject’s identity? This question refers to difference, but not in its usual conceptualization, synonymous with a border and the need to maintain or transcend it. By reconceptualizing difference, which I see as “re-creating” the meaning and linking it with “added” meanings, this article restores its original load (importance) in being an acting subject, mediated in otherness. For this purpose, the différance of Jacques Derrida is invoked and his statements about it combined with those of other philosophers, in whom I found what is related and/or complementary and extends not only Derrida's thought, but that which constitutes the main theme of this article. On the one hand, otherness is an impulse to the “work” of the difference, and on the other hand, it is its effect. What is the role of the “work” of the difference in creating the identity of the acting subject? In connection with the “shift” of the effect of its work – otherness, into the area of the identity of the acting subject, can this subject say about itself: this is still me? In this context, what is responsive ethics, which, I believe, should be included in the contemporary humanistic and social discourse about the subject?


Based on the issue of the genesis of subjectivity, the authors of the article turn to the Hegelian model, which captures the two-sided and fundamentally changeable nature of the relationship between subject and object. The article substantiates the idea that imagination, being considered outside of the context of psychologization or reduction of it only to the reproductive aspect, is a source of binary differences fundamental to philosophical thought. Following Hegel’s dialectical method, the authors note that the presence of the image already indicates the difference between the two dimensions of consciousness and knowledge. The image expresses the primary truth of substance and, at the same time, the way it is subjectively given. There is a differentiation of the subjective moment of Being with the realization of fantasy. All formations of Spirit are interpretations of the figurative series, primal scenes, the analog of which was studied by classical psychoanalysis. From this perspective, the genesis of such subjective modes as consciousness, self-consciousness and mind inevitably includes symbolization, interpretation of the "Self" images, cognizing, willing and acting in various situations and contexts. The study of the concepts developed by Hegel, Kennouche, Verene and Merleau-Ponty allows concluding about two arguments in favor of the fundamentality of imagination. This refers, on the one hand, to subjective imagination that generates meanings and the need for their interpretation and, on the other hand, to the initial form of synthesis, on the basis of which, the subject and object of cognition, formations of consciousness and types of knowledge characteristic of them are further distinguished. The image, being the first meeting of the concrete and universal, is capable of setting the plot of one or another form of subjectivity.


Having discovered this fact, the defendant refused to deliver. A majority of the court held that the parties had contracted on the understanding that that the cow was incapable of breeding. Accordingly, there had been a mistake not merely as to quality, but as to the very nature of the thing sold. It was thought that there was as much difference between an ox and a cow as there was between the animal the plaintiff bought and the one which both parties believed to be the subject matter of the contract. The difficulty with Sherwood v Walker when compared with the reasoning employed in Bell v Lever Bros is that the former looks suspiciously like a case in which the court has rectified what amounts to little more than a bad bargain. One way of viewing the difference between Sherwood and Bell is that the cases reveal a policy conflict in the way different judges approach the issue of risk allocation. On the one hand, there is a market-individualist approach to cases of mistake which seeks to uphold the sanctity of contracts and will therefore result in only the smallest number of cases in which the courts will upset a bargain on the ground of a shared mistake. On the other hand, there are cases in which the courts are more prepared to consider notions of fairness and justice in determining whether a mistake invalidates an agreement. It is not surprising that this alternative approach has developed in equity rather than at common law, as a simple glance at the form of relief granted in each case reveals a substantial difference. The common law answer in cases of shared fundamental mistake is that the contract is void ab initio – the contract is treated as if it never existed. In contrast, the equitable solution is to order rescission of the contract, but on terms that attempt to do justice between the parties. Thus, it is possible in equity to order rescission of the contract but then to add a rider to the effect that there should be a renegotiation of the contract on terms which take account of the fact in respect of which the parties were mistaken. In Solle v Butcher, the defendant leased to the plaintiff a flat. Both parties believed that the relevant property was not covered by the provisions of the Rent Restriction Acts, with the result that the defendant could charge a rent of £250 per annum. However, it later transpired that the relevant legislation was applicable with the result that the maximum rent payable was only £140. Such a mistake would not have been operative at common law, but the court held that the contract was voidable in equity, provided there was a fundamental mistake and no fault on the part of the person seeking relief: Solle v Butcher [1950] 1 KB 671, CA, p 690

Starting with the controversial esoteric employment of audio recordings by followers of the charismatic Muslim preacher Sharif Haidara in Mali, the article explores the dynamics emerging at the interface of different technologies and techniques employed by those engaging the realm of the Divine. I focus attention on the “border zone” between, on the one hand, techniques for appropriating scriptures based on long-standing religious conventions, and, on the other, audio recording technologies, whose adoption not yet established authoritative and standardized forms of practice, thereby generating insecurities and becoming the subject of heated debate. I argue that “recyclage” aptly describes the dynamics of this “border zone” because it captures the ways conventional techniques of accessing the Divine are reassessed and reemployed, by integrating new materials and rituals. Historically, appropriations of the Qur’an for esoteric purposes have been widespread in Muslim West Africa. These esoteric appropriations are at the basis of the considerable continuities, overlaps and crossovers, between scripture-related esoteric practices on one side, and the treatment by Sharif Haidara’s followers of audio taped sermons as vessels of his spiritual power, on the other.

The author of the article analyses the problem of the female emancipation in the little-known feuilleton “Amazonia: A Very Inept Story” (1924) by Mykola Chirsky. The author determines the genre affiliation of the work and examines its compositional structure. Three parts are distinguished in the architectonics of associative feuilleton: associative conception; deployment of a “small” topic; conclusion. The author of the article clarifies the role of intertextual elements and the method of constantly switching the tone from serious to comic to reveal the thematic direction of the work. Mykola Chirsky’s interest in the problem of female emancipation is corresponded to the general mood of the era. The subject of ridicule in provocative feuilleton is the woman’s radical metamorphoses, since repulsive manifestations of emancipation becomes commonplace. At the same time, the writer shows respect for the woman, appreciates her femininity, internal and external beauty, personality. He associates the positive in women with the functions of a faithful wife, a caring mother, and a skilled housewife. In feuilleton, the writer does not bypass the problem of the modern man role in a family, but analyses the value and moral and ethical guidelines of his character. The husband’s bad habits receive a caricatured interpretation in the strange behaviour of relatives. On the one hand, the writer does not perceive the extremes brought by female emancipation, and on the other, he mercilessly criticises the male “virtues” of contemporaries far from the standard. The artistic heritage of Mykola Chirsky remains little studied. The urgent task of modern literary studies is the introduction of Mykola Chirsky’s unknown works into the scientific circulation and their thorough scientific understanding.

The Age of Enlightenment is defined as the period when the universal ideas of progress, deism, humanism, naturalism and others were materialized and became a golden age for freemasons. It is wrong to assume that old and conservative Christian ideas were rejected. Conversely, freemasons put them into new general shapes and expressed them with the help of symbols in their daily routine. Symbols of freemasons had close ties with the past and gave them, on the one hand, a visible instrument, such as rituals and ideas to sense the transcendental, and on the other, intense gnostic aspirations. Freemasons put in a great amount of effort to improve themselves and to create their identity with the help of myths and symbols. It traces its origins to the biblical builders of King Solomon’s Temple, the posterity of the Templar Knights, and associations of the medieval craft guilds, which were also symbolical and became their link not only to each other but also to the secular world. In this work we analysed codified masonic symbols used in their rituals. The subject of our research is the universal Masonic idea and its aspects through the symbols in the daily life of the freemasons in Vilnius. Thanks to freemasons’ signets, we could find continuity, reception, and transformation of universal masonic ideas in the Lithuanian freemasonry and national characteristics of lodges. Taking everything into account, our article shows how the universal idea of freemasonry spread among Lithuanian freemasonry, and which forms and meanings it incorporated in its symbols. The objective of this research is to find a universal Masonic idea throughout their visual and oral symbols and see its impact on the daily life of the masons in Vilnius. Keywords: Freemasonry, Bible, lodge, symbols, rituals, freemasons’ signets.


Introduction .—In nearly all the previous determinations of the ratio of the specific heats of gases, from measurements of the pressures and temperature before and after an adiabatic expansion, large expansion chambers of fror 50 to 130 litres capacity have been used. Professor Callendar first suggests the use of smaller vessels, and in 1914, Mercer (‘Proc. Phys. Soc.,’ vol. 26 p. 155) made some measurements with several gases, but at room temperature only, using volumes of about 300 and 2000 c. c. respectively. He obtained values which indicated that small vessels could be used, and that, with proper corrections, a considerable degree of accuracy might be obtained. The one other experimenter who has used a small expansion chamber, capacity about 1 litre, is M. C. Shields (‘Phys. Rev.,’ 1917), who measured this ratio for air and for hydrogen at room temperature, about 18° C., and its value for hydroger at — 190° C. The chief advantage gained by the use of large expansion chambers is that no correction, or at the most, a very small one, has to be made for any systematic error due to the size of the containing vessels, but it is clear that, in the determinations of the ratio of the specific heats of gases at low temperatures, the use of small vessels becomes a practical necessity in order that uniform and steady temperature conditions may be obtained. Owing, however, to the presence of a systematic error depending upon the dimensions of the expansion chamber, the magnitude of which had not been definitely settled by experiment, the following work was undertaken with the object of investigating the method more fully, especially with regard to it? applicability to the determination of this ratio at low temperatures.

Abstract The present paper aims to present an inventory of Romanian middle contructions (se‑verbal constructions), and to extend the analysis to other structures (with or without se) that were not previously investigated, but exhibit the same characteristics, and seem to allow middle reading (adjunct middles). Since Jespersen (1927), middles were attested cross-linguistically, and the focus on middles is justified if we consider the fact that this is an interesting testing ground for theories of syntax, semantics and their interaction (Fagan 1992). Starting from Grahek’s definition (2008, 44), in this paper, middles are a heterogeneous class of constructions that share formal properties of both active and passive structures: on the one hand, they have active verb forms, but, on the other hand, like passives, they have understood subjects and normally display promoted objects. The corpus analysis will focus on the particular contexts in which the middle reading is triggered: i) the adverbial modification; ii) the modal/procedural interpretation of the event; iii) the responsibility of the subject; iv) the arbitrary interpretation of the implicit argument which follows from the generic interpretation (Steinbach 2002).

Under conditions closely simulating the natural modes of tuberculous infection in man normal guinea pigs have acquired tuberculosis by being exposed under two degrees of crowding to tuberculous cage mates in ordinary cages, where the food became soiled with excreta, bearing tubercle bacilli, and in special cages, with wire-mesh floors, where this source of infection was almost entirely eliminated. Guinea pigs were also exposed in the same room but not in the same cage with tuberculous animals. It was found that the relative tuberculous involvement of the mesenteric and tracheobronchial nodes showed a gradation of change from an almost completely alimentary infection to a completely respiratory infection. The disease involved the mesenteric nodes predominantly in the crowded ordinary cages, with much less or no affection of the tracheobronchial nodes. It was similarly, but less markedly, enteric in origin in the less crowded ordinary cages, the mesenteric nodes again being larger than the tracheobronchial nodes, but the difference in size was not so great. In the more crowded special cages the relative affection of these two groups of nodes alternated, so that in some the mesenteric, in some the tracheobronchial nodes were more extensively tuberculous. A disease characterized by less or no affection of the mesenteric nodes and by extensive lesions of the tracheobronchial nodes was seen in the less crowded special cages. Finally there was a massive tuberculosis of the tracheobronchial nodes with usually no affection of the mesenteric nodes in the frankly air-borne tuberculosis acquired by guinea pigs exposed in the same room but not to tuberculous cage mates. This gradation in the rô1e played by the enteric and respiratory routes of infection, as first the one and then the other becomes the more frequent channel of entrance for tuberculosis, would indicate that the penetration of tubercle bacilli by the one portal of entry inhibits the engrafting of tuberculosis in the tissues by way of the other portal of entry. It is apparent that in the special cages the opportunities for inhaling tubercle bacilli are at most equal to if not much less than in the ordinary cages; for in the latter dust from the bedding, laden with tubercle bacilli, is stirred up almost constantly by the animals, whereas in the special cages there is no bedding at all, and therefore, presumably, no more tubercle bacilli in the air than may occur in any part of the room. Nevertheless the route of infection was predominantly the respiratory tract in the special cages, especially in the less crowded, apparently because the enteric route had been largely eliminated. The greater predominance of the respiratory route amongst guinea pigs that acquired tuberculosis in the less crowded ordinary cages as compared to the lesser significance of this route in the more crowded ordinary cages would point in the same direction. These observations are in harmony with our knowledge that tuberculosis once implanted in an organism confers a certain degree of immunity to the disease. It is noteworthy that in a study of human autopsy material Opie (3) has found that when healed lesions are present in the mesentery focal tuberculosis in the lungs is seldom found, and that when first infection occurs by way of the lungs it tends to prevent the engrafting of the disease by way of the intestinal tract.
