Significant contributions to the theory of the hysteresis motor are briefly reviewed, and certain shortcomings of the present theory indicated. A novel approach to calculating the asynchronous torque, based on a surface integral instead of the customary volume integral, is presented. An experimental hysteresis motor, and several methods of testing the theory, are described, and deviations from the predicted performance examined with a view to establishing the magnitude of the various losses.

A balanced appreciation of poetry requires both the objective and subjective methods of literary criticism, but it is generally agreed, as W. W. Lawrence writes of the Canterbury Tales, that “the further we recede from our own times, the less can impressionistic analysis stand by itself, no matter how penetrating the imagination behind it.” The main direction of recent Chaucerian scholarship had been to show the inadequacies in purely subjective appreciation. Since in the Middle Ages literature was largely the preserve of the aristocracy and the Church, a knowledge of medieval society and religion is required in understanding poetry dealing …  Read more

The results of investigations on solid specimens of three granites show that, of the three variables, temperature, pressure and time, changes in temperature have the most profound effect on the rates of reactions in the specimens. Variations of both pressure and time also cause differences in the rates of reactions, but, are less important, on the whole than temperature changes. This statement, however, is subject to certain qualifications, depending on the temperature-pressure relationships to the granite liquidus curve. It is also shown that the solid specimens of the three granites begin to melt at almost the same temperature-pressure conditions as …  Read more

When two physically unrelated stimuli become associated through learning, a response conditioned to one of them may also occur in the presence of the other. This phenomenon, known as mediated generalization, has became a useful method for studying meaning, certain types of learning, and other central processes. Most investigators of mediated generalization (see Osgood, 1953, for review} infer that same "generalizing" or "mediating" process links the two stimuli, and hence a response conditioned to one of them tends to become "linked" to the other by this process. A special case of mediated generalization occurs when the stimuli are words or …  Read more

Through the ages, coronary artery disease has been plaguing mankind by the millions every year. Many sudden mysterious and dramatic deaths were attributed to this disease, yet people did not know how it worked. It was only during the advent of the 20th century that medical science began to probe this mystery, especially these last 35 years. [...]  Read more

The study of the problems of economic development, with reference to the so-called underdeveloped countries, has become a popular subject in recent years. The literature dealing with various aspects of economic development is multiplying rapidly. [...]  Read more

A large number of addition complexes formed between acceptor molecules containing Group IIIA elements and nitrogen donors are reported in the chemical literature, and with few exceptions (e.g., ethylenediamine), the donor molecules have contained only one nitrogen atom. It was therefore of particular interest to investigate the reactions of some "electron-deficient" molecules of Group IIIIA elements with hydrazine, the simplest substance having two nitrogen atoms which are potential electron donors.[...]  Read more

Positron lifetimes in a number of condensed substances have been measured using a resolving time of 10-9 sec. Positronium formation in alkali metal-ammonia solutions was round to drop rapidly when the concentration was increased above 0.1 molar. [...]  Read more

The histology of the seminiferous epithelium of the rat has been repeatedly investigated since the early work of Von Ebner (1871). These studies have led to the formulation of widely accepted concepts and have produced an extensive terminology. [...]  Read more

The morbidity and mortality associated with acute lesions of the brain are often the result of a diffuse or localized increase of cerebral tissue fluid, usually termed either cerebral swelling or cerebral edema. [...]  Read more

In general, the object of this work was to expose a low grade metamorphic rock to pressures and temperatures characteristic of higher grades of metamorphism, and observe any reactions that took place. [...]  Read more

The spruce bud moth Zeiraphera ratzeburgiana (Ratz.) is native to North and Central Europe, and has apparently been introduced in the northern part of the United States of America and Canada. The yellow spruce budworm Zeiraphera fortunana (Kft.) is indigenous to the North American continent and is generally found associated with Z. ratzeburgiana, causing the same type of damage.

The relation of muscle tension to mental work has been studied since the days of the Wurzburg school and the controversy over “imageless thought” (Humphrey, 1951, p. 187). In 1887, for example, Lombard (cited by Bills, 1927) found the knee jerk to be enhanced by mental effort, and Loeb reported that pressure on a dynamometer tends to slacken when accompanied by mental effort. Bills has also reviewed extensive studies by Golla, in which it was shown that the tonicity of many muscles measured during mental work was invariably heightened. Bills (1927) was apparently the first to test the functional significance …  Read more

The history of epilepsy has been traced as far back as Greek mythology. Hercules was attributed certain fits of anger, the description of which resembles epileptic seizures. Throughout the centuries and up to recent times, the disease was believed to have a supernatural cause. [...]  Read more

In anthologies or reference books Henry Vaughan is usually classified as either a "nature poet" or a "mystic" or sometimes as a "mystical nature poet." Much has been said on the subject of mysticism as applied to Vaughan and I do not intend to swell the already overwhelming tide of material on this subject, since I feel it is impossible conclusively to demonstrate Vaughan's mysticism from his poetry. Some of the critics who feel that Vaughan completely fulfills the requirements in the definition of a mystic (which may vary with different critics) or who assume Vaughan is a mystic and, …  Read more

The potato chip industry is expanding rapidly and is providing an ever increasing outlet for good quality potatoes. It has reached a level of importance at the present time which makes any problems it may have, the problem of the potato industry in general. In Canada potatoes constitute an important part of the agricultural economy and the substantial quantities used for chipping are helping to maintain favourable market conditions. Approximately 300 thousand acres are used for producing a crop averaging slightly less than 60 million bushels.  Read more

The object of this work was the isolation of an estrone conjugate, in a chemically pure form, from human pregnancy urine; and the characterization of this compound by classical procedures. In the course of the investigation, a partial separation of the various estrogen conjugates in pregnancy urine was accomplished through counter current distributions between nor-butanol and alkaline buffers.  Read more

Mayr, Linsley and Usinger (1953) have defined three levels of taxonomic study; the first or alpha level dealing with the recognition and description of new species, the second or beta level dealing with the arrangements of these described species into the hierarchical system and the third or gamma level dealing with the study of infraspecific variation and the evolution of taxa. It is probably the general rule that, in any one group, progress is made by passing through these various levels in turn as they suggest in the following quotation.  Read more

Qualitative, semi-quantitative, and quantitative x-ray spectrometric and optical spectrographic data are given for pyrrhotite, chalcopyrite and pyrite, and qualitative and semi-quantitative data for sphalerite, from the properties in Dore lake area in the Chibougamau district, Quebec.

The town of Buchans is four miles north of Red Indian Lake, in about the centre or Newfoundland, lat. 48° 50'W; long. 56° 46'W (see fig.1). The Buchans Mining Company Limited is a subsidiary of the American Smelting and Refining Company. The mineral rights are leased from Terra Nova Properties Limited, which is a subsidiary of the Anglo-Newfoundland Development Company Ltd. The town of Buchans is linked to the Canadian National Railway line at Millertown Junction by a private single-track line. This was the only means of ground transport to Buchans until a road to the Trans-Canada highway was completed …  Read more

This thesis reports a study of the motivational and emotional function of the midline and intralaminar structures of the thalamus of the rat. Following the work of Moruzzi and Magoun (1949), and the activation theory of emotion developed by Lindsley (1951), a great deal of psychological research has been devoted to the relation between behavior and the activity of the non-specific projection system (or systems) of the brain stem. Most of this work, however, has been directed toward the functions of the ascending reticular formation of the medulla and mesencephalon.  Read more

McFarlane, J.The house cricket Acheta domesticus (L.) is a very convenient laboratory insect; it is easy to rear (Ghouri and McFarlane 1958), it has a sufficiently short life cycle, the eggs and young nymphs are large enough not to necessitate any special apparatus to be manipulated, and, finally, neither diseases nor parasites are factors influencing the results. Nevertheless, A. domesticus has not been used very often by research workers, and the first to study seriously some aspects or its nutrition were Ghouri and McFarlane (1958), and McFarlane et al. (1959).  Read more

In 1943, Vogt (l) was able to show that the adrenal venous blood of animals contained a high concentration of cortical hormones several times the quantity extractable from the tissue. She concluded, therefore, that the hormones, for the most part, were not stored in the tissue but synthesized as required at a rapid rate. [...]  Read more

As recently as 1950 Schofield (1) was able to state that the electrophilic substitution of heterocyclic compounds lacked a comprehensive explanation. Since then considerable progress has been made both on the experimental and on the theoretical side, but there still remain many problems to clarify. The systematic investigations of Ochiai and den Hertog on the properties of heterocyclic N-oxides presented interesting new possibilities.  Read more

A subject that is beginning to be discussed more widely - heretofore, especially in Church circles, is the relationship between Sacremental Confession and Psyohotherapy* The problem centres mound the question of how the priest or minister can make use of either or both of these practices to the furthering of his office in the Church, and to the benefit of those committed to his charge. The question is. asked, are the two mutually exclusive, or is there some area in which they both can be used, or are they both to be used together? [...]  Read more

Mackenzie King and Canada lived together for many years and through many changes; the nature of the liberalism that kept them both reasonably content is the story of their marriage. In King's lifetime Canada erupted from a small, provincial rural country, practically and formally dependent on England, to a self-governing urban, industrialized country that was still provincial. But through it all Canada remained loyal to liberalism -or at least to that form of liberalism embodied by Mackenzie King and the Liberal Party. It may be true that all happy marriages are the same. The aim of this thesis, nevertheless, is …  Read more

Au début d'Octobre 1760, Voltaire reçoit à Ferney une ode grandiloquente d'un nommé Lebrun, secrétaire du prince de Conti, oh est évoqué le pitoyable sort d'une jeune héritière du grand Corneille "qui voit couler dans l'oubli ses destins et ses pleurs". Vivement ému, Voltaire éprouve aussitôt de généreux sentiments envers l'illustre dramaturge et sa déplorable héritière : "Pierre est un grand homme, déclare-t-il, il le sera toujours et nous, à côté, nous sommes des polissons."  Read more

This thesis describes a simple technique for the quantitative in vivo analysis of nonradioactive iodine. The method uses the X-ray absorption discontinuities for the detection of iodine in the presence of any other absorbing substance. [...]  Read more

The flow inside and outside of undeformed fluid drops suspended in an immiscible liquid in shear and hyperbolic flow was studied under conditions where the transmission of shear stresses across the interface was unimpeded. Excellent agreement with a previously developed theory was found. The effect of surface-active substances was to inhibit the internal circulation by forming an elastic interface capable of resisting shear stresses. The deformation, orientation and burst of drops in the two flow fields were investigated for a wide variety of systems. The deformation and orientation were in excellent quantitative accord with the theories due to Taylor and …  Read more

The production of good quality milk powders is a relatively recent enterprise. Although reference to edible milk powder dates back to the thirteenth century, it was not until the early twentieth century that milk powders were produced in any appreciable quantities. This comparatively slow development of the dried milk industry can be attributed to the inherent difficulties involved in the manufacture of whole milk powder of a satisfactory keeping quality.  Read more

Many parasitic diseases display symptoms beyond the areas invaded by the parasite itself. This suggests that toxic metabolic products of the pathogen diffusing in front of its advancing growth brings about derangements in unoccupied tissues at times far remote from the focus of infection.

Combustion has always been a subject of great interest. The oxidation of hydrocarbons and of related compounds has been studied by numerous investigators (1, 2, 3, 4) with an intention of elucidating the mechanism of these reactions. The investigations of the rates of oxidation of different hydrocarbons have been interpreted in terms of complex chain reactions involving free radicals such as OH, H, CH, C2 etc. (5), but as yet no unequivocal and satisfactory mechanism has been established for any combustion reaction.  Read more

Dans le roman-neuve, Les Hommes de Bonne Volonté, grande fresque qui dépeint vingt-cinq années de civilisation entre le 6 octobre 1908 et le 7 octobre 1933, Jules Romains passe en revue plus de trois cents femmes. Elles sont de toutes les classes, de toutes les conditions : duchesses, marquises, comédiennes, doctoresses, institutrices, gouvernantes, modistes, boutiquières, concierges, femmes de chambre et femmes de ménage, tireuses de cartes, procureuses, filles du trottoir; elles sont jeunes, mariées, mères, veuves, fiancées, vieilles filles, femmes trompées, femmes trompeuses et femmes entretenues. Certaines ne font que passer : ce sont ‘les oueds dans le sable’; d’autres …  Read more

On August 7th, 1960, in less than a year from now, it will be twenty years since an unemployment insurance scheme was started in Canada. It is perhaps appropriate at this time to review the development of the scheme,and evaluate its impact on the Canadian economy. [...]  Read more

The subject of integral transforms is generally introduced as an extension of the Fourier series representation of periodic functions. The fundamental expression, the Fourier integral formula, is derived from these series by a purely formal process, and, from it, the Fourier transform and the inversion formula are defined. The validity of these expressions is then ascertained by the proof of the fundamental theorem of convergence for functions satisfying given conditions. The Laplace transform and its corresponding inversion formula are introduced, in such discussions, in an equally formal manner by the simple expedient of a definition.  Read more

In the period since the end of World War II increasing attention has been focussed on the problems of economic development of areas commonly described as "underdeveloped". Within such areas much of this interest has come to the forefront following the achievement of national independence. And among the more industrialized nations the interest is partly the result of a genuine desire to aid the underdeveloped areas and partly to attempt to influence their political direction in the global ideological conflict of the midtwentieth contury.  Read more

Buckwheat ( Fagopyrum esculentum ) derives its name from the likeness of the fruit to a beech-nut (German :Buchweizen). It probably originated in the Himalayas (Stoletova, 1940). The earliest record of buckwheat cultivation was found in Germany in an old register dated 1436 (Hill, 1937; Ames, 1939). It is in no way related to wheat except that it has some importance as a "cereal" and is hence called a pseudo-cereal. [...]  Read more

Present day systematists have at least 150,000 species of angiospermous plants to deal with. Obviously, this large number must be divided into smaller groups, and several methods have been devised to separate them. The earliest workers used rather simple characters, resulting in very arbitrary divisions. For example, Theophrastus recognized trees, shrubs, under-shrubs and herbs. However, one modern taxonomist also uses this sort of division. Hutchinson (1926, 1948, 1959) divides the dicotyledons and monocotyledons into two main lines of development; i.e., the "Lignosae", or woody line, and the "Herbaceae" or herbaceous line.  Read more

The organic forms of nitrogen in the soil are derived largely from plant residues, such as stubble, weeds, leaves, and pine needles etc. The amount of protein in these organic materials is often very large. For example, the protein content of cereal straw and wood shaving may be as much as 2 or even 15 per cent, and the protein content of certain defatted meals, may be 40 or even 60 per cent. The phenomenon of growth and death of bacteria in ordinary culture media has been studied in considerable detail.  Read more

"To produce a mighty book, you must choose a mighty theme", said Herman Melville in Moby Dick. Despite conspicuous differences in approach, the underlying theme of Moby Dick and Pierre is indeed a cosmic one. It is a theme with which Melville grappled throughout his life; one with which all great artists and religious teachers have wrestled since the dawn of human expression, and which so intensely concerned the first New Englanders and many of their descendants.  Read more

The surgeon is often called upon to treat patients suffering from post-hepatic obstructive jaundice. This treatment may simply consist of removal of stones from the common duct or relief of spasm or stenosis of the sphincter choledochus by sphincterotomy. On the other hand, stricture or tumour of the duct may necessitate the performance of extensive reconstructive procedures on the biliary channels. The first side-tracking operation for obstructive jaundice was carried out in 1882 (180) at which time the gall bladder was anastamosed to the colon in seven stages over a seventeen month period.  Read more

A radiometric survey of Redwater Oilfield was carried out during the summer of 1956. The field work included collections of 450 radon samples, 4000 total count determinations, and collections of 865 soil samples for analysis from 200 holes, 5 feet deep, drilled approximately 1300 feet apart. During the course of the field season it was observed that radiation measured at the surface of earth or just above it comes from within 0-0. 3 feet in loams, 0. 6 = 1. 5 feet in sands, and about 2 feet in peat. It was also noticed that the radon content was lower …  Read more

Lodging in small grains is often responsible for losses in crop yield and quality. Due to difficulties in employing modern harvesting practices, in lodged crops, the cost of production increases, both because of time lost and because of increased labour requirements. [...]  Read more

A detailed study of certain Grenville rusty paragneisses was made. The work includes a description and discussion of the petrography; a study of the variations of certain elements in biotites, garnets and total rock with advancing metamorphism; and a classification of these rocks into Eskola's metamorphic facies.

After more than two hundred years the reputation of Daniel Defoe has become solidly entrenched in the history of English literature. No respectable anthology of eighteenth century writing would omit mention of this considerable name, and at least a fragment of either ‘Robinson Crusoe’ or ‘A Journal of the Plague Year’. Discussion of the development of the English novel generally begins with the name of Defoe: He is seen as being either the father, or as being the vital link connecting the earlier moral fable and the modern complex novel. In either case, his name and his work assume the …  Read more

Nuclear three-body potentials are calculated using the renormalized non-relativistic meson theory of Chew and Low. Multiple scattering effects are taken into account by their "one-meson" approximation. The potentials are found to have a relatively short range. [...]  Read more

Throughout historical time men have attempted to explain the origin of mineral deposits. Many theories were presented during this period, to be contested or supported according to the experience or beliefs of the critic, but few have been discarded because the genesis of mineral deposits can be explained in many ways. This lack of agreement on the origin of mineral deposits testifies to their diversity, to the ambiguity of information we gather concerning them, and particularly to our lack of knowledge of the earth's internal structure, composition, and physical-chemical processes.

Karl R. Popper, Professor of Logic and Scientific Method in the University of London, is primarily a physicist and a philosopher of science. In this capacity, he is interested in: the criterion demarcating science from pseudo-science, the method of science, and especially the method of social sciences. He thinks the method employed there is the cause of the trouble, since it is based on a misunderstanding of the method used in the physical sciences.  Read more
