The present investigation is entirely original in the sense that all results reported are based on the author's own work. Human and animal experiments reported by other authors on this subject have been either numerically insufficient or fail to allow the immunizing efficiency of the individual antigens in the combinations to be determined quantitatively. This investigation is unique in that the experiments were primarily designed to provide adequate data for significant statistical analysis. [...]  Read more

In undertaking a study of the case work process involved in helping the child to participate in his move in to an adoption home, the writer hopes to be able to clarify her own thinking and philosophy concerning this phase of adoption. It will also be a means of evaluating the skill and technique which she has been able to develop in this process. An attempt will be made t o bring out many of the beliefs and convictions, concerning a child's capacities, growth and development, which the writer feels are basic to a social worker, if she is to …  Read more

The objeet of this study is to discover whether there are common factors in the personality structures of truant and delinquent boys. It will also attempt to answer the following related questions: 1. What is the relation of truancy to the more serious forms of delinquency -- is it merely a preliminary stage or does it spring from different causes? 2. What are the specific emotional disturbances that find expression in truancy and delinquency? 3. What common intellectual patterns are found in the truant group that might account for maladjustment to the school Situation? [...]  Read more

[...] In order to throw further light upon the exact nature of this polymer-thiol interaction, it was felt that it would be of interest to carry out a careful study of the role of atmospheric oxygen and other oxidizing agents whioh may be present in Systems of this kind. The work presented in this thesis, therefore, represents a study of these factors in the interaction of polybutadiene and polystyrene with a thiol in an emulsion medium.  Read more

[...] In the present paper, the methods of Jacobian analysis are extended to systems determined by more than two independent variables. A detailed analysis is given for systems of type (a) treated by Goranson, consideration of which was begun previously by the author in his Master's thesis (13) . Brief treatments are given of cases (b) and (c).[...]  Read more

The present study proposes a detailed examination of the Irish migration to Montreal between 1847 and 1867, that is to say between the Famine and Confederation. For vast numbers of Irish, Quebec and Montreal were of course merely staging-points in a weary journey whose end lay in Upper Canada or, more often, in the United States of America. [...]  Read more

[...] In the investigations to be described an attempt was made to obtain a chronic epileptic animal through the prolonged accumulation or potentiation of acetylcholine in the cerebrum by injecting the anticholinesterase di-isopropyl fluorophosphate (DFP), the action of which is almost irreversible, into the carotid artery of cats. It was hoped to restrict the action of this potent chemical to the brain, or even to one hemisphere of the brain, and thus to avoid most of the peripheral systemic effects of the drug.[...]  Read more

The ever increasing industrial utilization of numerous organic liquids for condensation purposes in a vast multitude of processes is a fact which makes the determination of condensing vapor film coefficients a virtual necessity. Such observations are, of course, of primary interest to designers of heat transfer equipment. Since any discussion of condensing vapors is intimately associated with the film concept, it would be well to devote some space to the history of this concept. [...]  Read more

L'oeuvre dramatique de Gide est assez mince, cependant l'intdret qu'il a porte au theätre nfa jamais cesse durant toute sa carriere. Nous en trouvons des signes dans ses traductions de Shakespeare, dans ses commentaires sur l'oeuvre de tel ou tel dramaturge, sur l1Interpretation des grands roles, ou meme dans des discours sur l'art du theätre comme cette Evolution du theätre auquel nous aurons souvent recours.[...]  Read more

The problem of hypertension and its relation to the kidney, and lesions throughout the vascular tree has excited considerable interest since the days of Richard Bright. In the human, hypertension may be associated with changes in the arterioles generally, although Chiefly in the kidneys but frequently the picture of hypertension may be present without the expected pathological findings. Severe degrees of arteriösclerosis may be found in chronic hypertension but again this is not a constant feature.[...]  Read more

Manganese oxide compounds prepared in different ways adsorb protactinium with different efficiencies. X-ray analysis of these types shows a rough correlation between crystal structure and adsorption efficiency. Careful experiments on protactinium adsorption were carried out on four widely different crystal forms, including pyrolucite and cryptomelane. The adsorption efficiencies of these types were correlated semi-quantitatively with the surface areas of these powdered compounds as viewed in the electron microscope. [...]  Read more

[...] The chief objects of the present investigation are: 1. Continuation of the detailed study of glycolysis in blood. 2. To ascertain whether glucose is the sole source of pyruvic acid formed in the red blood cells during storage. 3. To determine the reason for certain fluctuations observed by Mrs. Andreae in the copper-reducing values of protein-free filtrates of preserved blood containing added dextrose. 4. To ascertain whether there is any relation between the loss of viability of the red blood cell and its glycolytic state.  Read more

This paper deals with the results of a study and review of the petrographical, stratigraphical, and structural characteristics of certain basic intrusives, generally distributed throughout the Canadian Shield, which are described as "diabase" dykks and sills. It is found that the cutting relationships reported afford positive evidence of at least four sequences of "diabase" intrusion. Except for degree of alteration, the sequences resemble each other so closely that positive age correlation on a petrographical basis is precluded. The dykes have predominant north west, north-south, and north a act trends. The writer concludes thab structural evidence suggests" the hypothesis that the …  Read more

[...] Dans le premier chapitre on considérera des fautes lexicologiques qui n'embrassent que des mots ou des expressions isolés puis dans le deuxième chapitre on discutera des fautes d'interprétation qui ont plus d'importance. Sous les deux titres on retrouvera dee Inexactitudes sémantiques en plue des irexactitudee stylistiques. Tandis que les fautes rassemblées dans le premier chapitre sont faciles à reconnaître et à analyser, celles du deuxième devienaent plus complexes.[...]  Read more

The land use survey is becoming an increasingly important item in geographic studies. This is especially so when such studies are undertaken for the solution of land use problems, because a knowledge of the present use of the land is usually deemed basic to efficient physical planning. Canada has many land use problems which need to be solved if the natural resources of the nation are to be conserved for the welfare of present and future generations. But Canada is a country of wide extent and scattered population, so that her geographers, few in number, need to find some method …  Read more

[...] The work presented in this Thesis, it is hoped, will aid in clarifying some of the features of the relationship of experimental atherosclerosis to renal hypertension in animals and will, perhaps, throw some light on the relationship in man. Further, it may clarify some of the differences and similarities between experimental cholesterol arteriosclerosis in animals as compared to atherosclerosi in human beings.  Read more

[...] Much work has been done in animals using purely artificial means of inducing hypersensitivity. Only a few workers have attempted to simulate hypersensitivity in animals, as it occurs in humans. Therefore, the study o hypersensitivity In animals, produced in guinea pigs by inhalation of the antigenic substance, might well show features of both anaphylaxis in animals and allergy, (i.e. asthma) in humans. It was with these features in mind that the present problem was undertaken.  Read more

[...] The present investigation was concerned with a few reactions which may occur In one of the most widely used polymerization processes, and It was hoped that their elucidation might clarify some of the factors governing the structure and properties of the polymer. This work could be discussed without reference to polymerization but it is felt that much of its interest and meaning would be lost in so doing. For this reason the more pertinent facts and theories of polymer reactions are included in what follows. Familiarity with the general field of polymer chemistry is assumed.[...]  Read more

The investigations which led to the discovery of vitamin P were undertaken by Armentano, Szent-Gyorgyi and co-workers to determine why purified ascorbic acid, in contrast to the crude product, was a therapeutic failure in vascular purpura. Since earlier work on plants had shown that ascorbic acid was coupled with an essential flavone, the experimenters proceeded to isolate this substance. From about 200 kg of lemons or 70 L of lemon juice, approximately 2 g of flavone material could be obtained, which because of its yellow color and origin was named citrin.[...]  Read more

Before discussion of the physiology of the gastro-intestinal motility it would be well to review briefly the anatomy of the region. The parts are: esophagus, stomach, small and large Intestine. The esophagus or gullet is, with the exception of pylorus, the narrowest and one of the most muscular parts of the whole alimentary tract. In the neck anteriorly lies the trachea and in the groove at each side, between the trachea and esophagus, the recurrent laryngeal nerve ascends to the larynx.[...]  Read more

Acceleration methods nam be divided broadly into two classes. The first includes all methods in which a magnetic field is used to bend the particles during acceleration into spiral or circular orbits; in the second are all systems in which the particles are accelerated along straight paths.We shall be concerned here chiefly with the principal accelerators in the first class. The theoretical problems concerned with the stability of the orbital motion ere investigated. Account is also taken of the effects on the motion of loss of energy through radiation. The question of the maximum energy attainable in the various accelerating …  Read more

The work presented in this study on the corn gluten of stripper-starch centres about two problems. The first problem was to determine the form in which the gluten is present in stripperstarch, and the nature of its association with the starch. The second problem was to find a neutral solvent capable of extracting the complete native corn gluten complex from the accompanying starch without dispersing the latter. [...]  Read more

The problem which is the subject of this study originated in part from a teaching device employed by one of the professors of the Education Department. It was his custom as he spoke of national systems of education, etc. in each case to represent diagramatically on the blackboard, the learner, his relation as a scholar to the life outside the school walls, and the avenues or sources of his learning. By virtually a process of induction, these components came to be seen to occupy the stage in every discussion of educational theory. Not only did they appear, but they offered …  Read more

Very soon after it was established that, as a general rule, the passage of an electric current through an aqueous solution results in the liberation of hydrogen at the cathode and oxygen at the anode, the early workers in this field realized that under these conditions electricity may be regarded as a potential reducing or oxidizing agent. The experiments of Faraday, Schonbein and many others proved this assumption to be quite tenable, and that it had a wide range of applications both in the sphere of organic and Inorganic chemistry.[...]  Read more

[...] The experiments to be presented in this thesis have been undertaken with the object of further studying the role played by the adrenal cortex in the protein metabolic changes following stress, as well as other factors which may have an influence upon these changes. The author claims to a "contribution to knowledge" lie in the belief that (1) the data to be presented provide a new interpretation for the changes in urinary nitrogen observed in the rat following adrenalectomy. (2) The data referable to urinary nitrogen changes following fracture lend support to the concept that the adrenal cortical hormone …  Read more

The role of phosphorus in the national and world problem of food production and adequate nutrition is so great that it has sometimes been called the master key to agriculture. Its importance is indicated by the fact that low crop production is associated more often with a phosphorus deficiency than with a lack of any other element. Pierre (37) says, "Phosphorus is so basic to the whole problem of crop production that probably no other subject in the field of soil fertility has received more attention through the years than the phosphorus problem in its various soil-plant and soil-animal relationships, …  Read more

Oxygen consumption measurements on thirty-two women and thirty-six female guinea pigs were used to compare basal and resting metabolism in these species. In order to remove variations due to differences in body size the results were expressed per unit of "Metabolic weight" (Wb). It was found that heat production values were significantly higher for the guinea pigs than for the women. No difference between basal and resting metabolism occurred except in the older group of women. A significant difference between the heat production values of the two age groups was noted. There was no difference in the variation of heat …  Read more

Linseed oil meal is the most abundant vegetable protein supplement produced in Canada and hence occupies an important place in the livestock feed industry. By virtue of its conditioning effects and protein content, it is widely used in the feeding of larger animals including swine. In the latter case, meat meal or tankage is used as an additional protein supplement. In poultry rations however, even after the inclusion of animal protein supplements in amounts and of a quality normally considered adequate, it has not been possible to use linseed oil meal to any appreciable extent without inferior growth results.  Read more

Le roman historique fut popularise en Angleterre par Walter Scott. Ses romans eurent une influence tres profonde sur les romanciers trangais, surtout sur les jeunes romantiques. Dans les romans de Scott, on voit l’histoire, plus ou moins juste, comme un fond, et les vrais personnages comme les personnages de second plan, on y trouve le goüt de la violence, des conjurations, des longues descriptions qui donnent la couleur looale. Les jeunes romantiques, parmi qui on ne va considerer ici que Vigny et Dumas, trouverent dans les romans de Scott et les drames historiques de Shakespeare une tres grande Inspiration.[...]  Read more

A series of experiments has been conducted in which asparagus, beans, beet petioles and peas were frozen at three different rates. Apparatus was set up for the microscopic inspection of sections of frozen vegetable tissues and for the taking of photomicrographs of these sections. A series of forty-four photomicrographs is presented showing sections of fresh, frozen and thawed materials. Results indicate that in freezing vegetables the slower the speed, the larger are the ice crystals formed. It has been shown that ice forms in and around water conducting vessels to a greater extent than in neighbouring areas of undifferentiated parenchyma …  Read more

[...] The investigation is less complete than desired, chiefly because the writer has not been able to visit the property. Accordingly, no first-hand observations on the field relationships are possible. Furthermore, the suite of specimens on which the study Is based was not collected primarily for this purpose, and has certain deficiencies, e.g., the relatively unaltered county rock type away from the mineralized zone. Despite these limitations, the description of the unusual mineral association and some conclusions derived therefrom are regarded as worthwhile contributions.  Read more

The search for a satisfactory and complete explanation of acute and chronic ulcerations of the stomach and duodenum of man has been carried on by numerous investigators in both laboratories and clinics for many decades. Although much information has been obtained during the course of these varied investigations it is readily apparent that no all-embracing explanation of these lesions has been agreed upon, nor, as yet, has a theory been formulated which will successfully withstand criticism. This, in itself, suggests two chief possibilities. Firstly - that there is no single explanation of "peptic" ulcer. It may be a condition, the …  Read more

Shortly after the production of experimental diabetes by von Mering and Minkowski in 1889 it was noted that the pancreatectomized dog manifested not only impairment of carbohydrate metabolism but evidence of altered fat metabolism as well with a tendency to deposit fat in the liver. Sandmeyer in 1895 demonstrated the beneficial effect of feeding raw pancreas in the amelioration of this complication and postulated that the presence of certain digestive enzymes of the pancreas was essential for the prolonged survival of dogs after pancreatectomy.[...]  Read more

The name of Arnold of Rugby is one which has become so hallowed not only by tradition but by convention that the question may well be asked why a further survey of his significance as an educator should be undertaken. Thomas Arnold was a man upon whom the white light of controversy beat while he lived, and whose works certainly lost nothing in fame and discussion after he had died. His dramatic and sudden death evoked not only a great biography which might well otherwise have been at least postponed and perhaps never prepared, but brought into vivid relief the …  Read more
