1962 — Property rights in airspace, (landowners and the right of flight).Résumé
In the vast expanse of the law, there is probably no branch or division which can trace its history farther back, or which is more important to the general public, including as it does innumerable elements of everyday life, than that branch of law dealing with Private Property. The term ‘Property’ has a bewildering variety of uses. However, basically it is used in two senses: that of ownership or title, and also to designate the ‘res’ over which ownership is or has been exercised. This one word is used to express both the genus and the species. The relationship between … Lire la suite

1962 — A study of some methods of measuring ablation and run-off on an arctic glacier.Résumé
There has been a great increase in the amount of scientific work done in the Polar Regions in recent years but the accuracy of many of the measurements is uncertain. This methodological study was undertaken as a preliminary basis for an examination of the relationships between ablation and run-off on an arctic glacier. It is an attempt to obtain an estimate of the accuracy which can be expected in such a study through the examination of some of the methods of measuring ablation and run-off. At the same time, it is an attempt to define the probable limits of accuracy … Lire la suite

1962 — Mysticism and prophetism.Résumé
The techniques and principles of mysticism are described, and illustrated from the life of a Hindu mystic and from the teaching of St. John of the Cross. The problem is then stated -- what is the relation between mysticism and Hebrew prophetism? Can the latter be described as mystical, or is the Hebrew mind alien to mysticism? We then look at the Hebrew religion as it makes contact with Baalistic prophetism, an early form of mysticism. In the struggle that ensued between the two, we discover the religion of Israel absorbing something from Baalism but asserting its own peculiar genius. … Lire la suite

1962 — Salt distribution in sea ice.Résumé
The water of the oceans (11) contains about 3.5% by weight of dissolved inorganic salts in addition to organic substances and any suspended matter which may be present. The quantities and identities or these ions have been the subject of much investigation and are now generally accepted. The dissolved salts have a profound effect on many of the physical properties of sea water. Surprisingly, although the total weight of dissolved salts is not always the same, it has been found that the relative proportions of the various major constituents remain virtually unchanged, except when extreme dilution is encountered.

1962 — Raniri and the Wujudiyyah of 17th Century Acheh.Résumé
The subject of this thesis is a critical study of Nuru'l-Din al-Raniri's refutation of Hamzah Fansuri's mystical philosophy, based on two of Raniri's works: the Hujjatu'l-Siddiq li daf'i'l-Zindiq (Maxwell Text no. 93, Royal Asiatic Society, London), and the Tibyan fi Ma'rifati'l-Adyan (Leiden Text cod. or. 3291), both of which have been reproduced in facsimile in Voorhoeve's Twee Maleise Geschriften van Nuruddin ar-Raniri (1955); and on the works of Hamzah Fansuri containing various collections of mystical poems and two prose works: the Asraru'l-'Arifin and the Sharabu'l-'Ashiqin or Zinatu'l-Muwahhidin, all of which have been edited and transliterated into the Roman script and … Lire la suite

1962 — Raniti and the Wujudiyyah of 17th century Acheh.Résumé
Trade has been going on in the Indonesian Archipelago since ancient times, linking it with the various parts or Asia and with the Middle East and the lands of the North. In Roman times, the Alexandrian geographer Ptolemy, who flourished in the year 160 of the Christian era, mentioned for the first time an area in the Archipelago, referring to it as the 'Golden Chersonese.' This prosperous land seems now to have been identified with the Malay Peninsula. Along with trade came changing religions and various cultural elements imparting upon the people their distinctive impressions. Islam too had come via … Lire la suite

1962 — The effect of rearing conditions on maze learning.Résumé
The animals used in the present experiments were male hooded rats from the Royal Victoria Hospital Colony. They were from 19 to 21 days old when obtained. The rearing conditions were modeled after those of Hymovitch (1952). The “free environment” was a wooden box (30 x 60 x 6 in.) with a wire screen top. It contained a tunnel, barriers, blocks, and elevated runways. The restricted environment cages were made of stave-pipe 15 in. high and 8 in. in diameter; holes at the top and bottom admitted light and ventilation without permitting vision of the outside surroundings. A single rat … Lire la suite

1962 — L’art de la nouvelle chez Gobineau.Résumé
Pour le lecteur français cultivé, comme pour l'étudiant en littérature française, le nom de Gobineau n'a longtemps évoqué qu'une seule œuvre : ‘L'Essai sur l'inégalité des races humaines’ ; et ce livre, qui fut loin d'enthousiasmer les lecteurs du XIXe siècle, fait horreur aux générations qui ne l'évoquent qu'à travers le spectre du racisme nazi. Cependant, Joseph Arthur de Gobineau ne fut pas l'aristocrate raciste et hargneux que son livre pourrait faire imaginer. Lire la suite

1962 — Evaporation induced by swirling water.Résumé
This work, aimed at saline water conversion, investigates the possibility of inducing evaporation in the low pressure core created at the centre of a mass of swirling water discharging through a central orifice. Navier - Stokes equations, applied to a simplified flow model, produce solutions involving an experimental "efficiency factor". Fair agreement with the experimental data is achieved by using an empirical "mixing factor" The tangential velocity increase and the corresponding static pressure decrease towards the centre of the swirl, as predicted by the ideal fluid theory, are not materialized in practice.

1962 — A study of gliomas and other central nervous system lesions based on fluorescence microscopy after staining with acridine orange.Résumé
Quick frozen section of brain tumors, as well as the smear technique developed here at the Montreal Neurological Institute by the late Dr. W.V. Cone are extremely valuable means for arriving at a preliminary pathological diagnosis which can be relayed to the surgeon prior to the completion of an operation. We felt, however, that the fine histological distinction between benign and malignant intracranial lesions which arises in some cases could not be readily resolved by using the above techniques alone and that, perhaps, a technique could be devised to help clarify these problem cases.

1962 — Studies on diseases of birdsfoot trefoil with special reference to the cause of wilt.Résumé
Birdsfoot trefoil, Lotus corniculatus L., and closely related species are long-lived perennial legumes, which have a potential in agriculture for replacing clovers and alfalfas in locations which have proven to be generally unsuitable for the growth of most other legumes. However, the life of birdsfoot trefoil has been only two or three years in Quebec, instead of at least ten which is expected in the southeastern area of the United States (Drake 1958). The reduction in the life span of this plant in Quebec is generally attributed to "winter killing," but the cause of winter killing could be due to … Lire la suite

1962 — Variation in two populations of Gryllus bimaculatus de Geer (Orthoptera: Gryllidae).Résumé
Gryllus bimaculatus de Geer is one of the most widely distributed species of field crickets and ranges from South Africa, the Mediterranean basin, Southern Asia and the East Indies to Japan. (Cousin, 1956, 1961). Chopard (1938) found that this species does not range north of the northern shore of the Mediterranean. Cousin (1941) was the first to recognize the significance of a regular phenomenon in the variation of pigmentation of G. bimaculatus specimens reared in the laboratory from collections made in the field in southern France.

1962 — The lake breeze in relation to tobacco leaf fleck in southwestern Ontario.Résumé
The relationship between the meso-climate and tobacco leaf fleck is investigated by correlating wind, temperature and relative humidity records of six stations within the flecking area with the fleck index. Criteria for the recognition of the lake breeze are established and the correlations that exist between the lake breeze and flecking are shown. It is concluded that the lake breeze correlates effectively with flecking when the lake breeze is accompanied by a southerly gradient wind. The lake breeze and meteorological processes connected with it may provide a mechanism for fumigation in the manner suggested by Mukammal (1959) and (1960). Lire la suite

1962 — The history of tradition criticism with special reference to the works of Hermann Gunkel, Hugo Gressmann, and Sigmund Mowinckel.Résumé
The changing values of the twentieth century. The uncertainties inherent in present- day biblical scholarship. The work of the British Myth and Ritual School as symptomatic of an altered attitude towards the basic values inherent in primitive tradition. The enigmatic character of the sudden emergence of this school in Britain in 1933. The reasons for the emergence of the British Myth and Ritual School. An analysis of its distinctive features. Its relationship to previous trends in anthropological studies, in general, and to Continental biblical scholarship, in particular. Pedersen and Mowinckel, Gunkel and Gressmann.

1962 — The response of oat crops and succeeding hay crops to chemical fertilizers on different soil types in southwestern Quebec.Résumé
In a recent publication* by the Quebec Fertilizer Board for farmers, some emphasis was placed on the fact that the soils of Quebec are "undernourished" and are gradually becoming "impoverished." Figures were also presented which indicated that there was a general decline in fertilizer usage during the 1945-1956 period. It has been the general opinion that the soils of Quebec are not sufficiently fertile to warrant this decline in the use of commercial fertilizers. To study the situation more thoroughly, the establishment of field experiments appeared to be a logical endeavour. Lire la suite

1962 — Imago Christi: an investigation of the doctrine of man according to the later writings of Paul Tillich (Systematic Theology II) and Karl Barth (Church Dogmatics III, 2).Résumé
Kierkegaard was utterly convinced that apologetics were a form of treason arising out of stupidity, and that whosoever invented them has been a second Judas within the Christian world. It is true however, that apologetics have been the concern of Christian Theologians throughout the History of the Church. The twentieth century does not constitute an exception to this rule in spite of the passionate warning of the Danish philosopher and its profound repercussions in the theology of K. Barth. The demythologization programme, championed by Rudolph Bultmann in the field of New Testament studies, seems to pursue once again the defence … Lire la suite

1962 — Potassium and brain metabolism.Résumé
In 1811, Nicolas Vauquelin reported the presence of potassium in brain (408). Ana1yzing the ash residues of muscle, Liebig found more potassium than sodium (cited by Kaunitz,211). He suggested that potassium occupies an intracellular position and sodium, an extracellular position, in muscle tissues (see Tower,392). Since that timea long series of analytical studies have shown that an analogous distribution of the two elements exist almost universa1ly in bacterial, plant and animal cells (see Reinberg,J27). Fenn has defined this phenomenon, writing: "As is well known, potassium is of the soi1 and not the sea; it is of the cell but not … Lire la suite

1962 — Parent, child, and television: interaction in communicationRésumé
In this research, I propose to study the attitudes and behaviour of young children towards a television symbol, "Maman Fonfon". I also want to see how the mothers of these children react to the popularized image of "Maman Fonfon," and if their reactions may be related in some way to those of their children. The child, especially if he is quite young, is strongly affected by his mother's attitudes, since she is usually the most important adult figure in his world. Finally, I hope to find out how the symbol of "Maman Fonfon," as it has been built up by … Lire la suite

1962 — An Investigation of the effect of air flow on the insertion loss of a volume resonator.Résumé
The decrease in the insertion loss of a volume resonator caused by an increase in air flow velocity was experimentally investigated. This reduction was attributed to viscosity and heat conduction effects, and also to the sound that originated at the mouth of the volume resonator due to the turbulence created there.

1962 — Air carrier’s liability in AustraliaRésumé
In April, 1959, the Commonwealth Parliament enacted an Act, the Civil Aviation (Carriers• Liability) ( 1) Act 1959. This Act deals with international carriage by air and carriage by air within Australia. It made far reaching and perhaps revolutionary changes to the law of carriage by air within Australia. This thesis was written for the purpose of describihi those changes and their effect and to describe the law applying to carriage by air which is not covered by the Act. [...] Lire la suite

1962 — The effect of anxiety on self-stimulation of the septal area in the rat.Résumé
In 1954, when Olds and Milner discovered rewarding areas in the rat brain, it seemed as if the drive reductionists would have to revise their basic theory. Until that time the dogma was that an action would be reinforced if it led to a reduction in drive or drive stimuli. The idea that an increase in stimulation could be rewarding was contrary to the most widely accepted theories, and, in fact, the affect of an increase in stimulation was commonly regarded as punishing.

1962 — Phospholipid metabolism in brain.Résumé
For many years, phospholipid has been considered as perhaps one of the most obscure fields in biochemistry. Indeed, although the history of the study of phosphorus associated with lipid dates back to at least the 1880's (1, 2), subsequent investigations in this area have been characterised by the almost complete inability to penetrate the enigma surrounding the biological synthesis of the metabolic function of phospholipid.

1962 — Response to novel stimuli and arousal in rats.Résumé
The relation between drive state and general level of activity has been a frequent topic of investigation in psychology since Richter's first systematic experiments on the activity of the rat in 1922. Most of the studies in this area, designed to support the notion of an "energizing" function of drive, have reported a regular increase in activity with moderate food deprivation (Siegel and Steinberg, 1949;Finger, 1951; Dashiell, 1925, as cited in Alderstein and Fehrer, 1955). In recent years this relation has come to be taken so for granted that some current textbooks have used it as the basis for defining … Lire la suite

1962 — Magnetoresistance at medium and high fields in indium antimonide and indium arsenide.Résumé
Measurements have been made of the angular dependence of magnetoresistance and Hall effect of indium antimonide at room and liquid air temperatures in fields less than 7,000 oersted, and of the transverse magnetoresistance at room temperature of indium antimonide and indium arsenide in transient fields up to 3 x 10^5 oersted. The lower field results confirm the existence of a small positive longitudinal magnetoresistance not due to sample and field misalignment but due to either a cubical anisotropy of conduction properties or to sample inhomogeneity. Some structure in the angular variation is apparent at 77°K. Lire la suite

1962 — Availability of soil phosphorus and fertilizer response for oats in selected Quebec soils.Résumé
Radioactive and stable isotopes have been widely used in studies of biological problems in the last two decades. These labelled atoms or molecules allow undertaking experiments where ordinary chemical and instrumental measurements are not practical. They can be readily detected, traced or determined quantitatively, even at extremely low concentration (32). Radioactive phosphorus labelled fertilizers have made possible the determination of the quantity of phosphorus in the plant derived from applied fertilizer, hence the quantity derived from the soil can be calculated. Such information has indicated that the relative proportion of soil to fertilizer phosphorus absorbed by plants is related to … Lire la suite

1962 — An experimental study of of the role of the lymphatic tissue in trauma-resistance.Résumé
Noble and Collip's discovery (1942.A.) of a standardized way to produce traumatic shock in experimental animals was followed very shortly (1942.B.) by their accidental discovery of the phenomenon of trauma resistance. This was shown to be a resistanceto the shock state which in normal animais follows heavy doses of trauma. The development of tolerance to stress and the resistance to shock which ensues, have been shown and studied quite extensively since their first description. Lire la suite

1962 — Elastic stability of particular three-dimensional rectangular rigid frames.Résumé
The study is limited to space frames having two planes of lateral symmetry and the buckling loads associated with sidesway in the directions of the planes of lateral symmetry and torsion are obtained for particular one-storey spaceframes. Resulta show that in general the critical mode of buckling is the antisymmetric mode in the direction of least lateral rigidity of the frames. It is also shown that when the torsional stiffnesses of the members are ignored, there are cases where the buckling loads associated with the three modes of buckling are all equal.The general equations governing lateral in-the~plane buckling of symmetrical … Lire la suite

1962 — High density low cost housing developments in Hong KongRésumé
Because of its grave implication within the economic and social development of a community, inadequate housing constitutes one of the most serious problems of modern society. Much has been written about this problem and many plans have been devised to attack it, but seldom, if ever, have studies been made on housing situations as unique as that which faces Hong Kong to-day. Hong Kong’s “problem of people” is well known; seen from another angle it is also a “problem of land”. In the last decade and a half its population has quintupled and is steadily rising.

1962 — Intestinal microflora associated with enteritis of early weaned pigs.Résumé
Enteritis is one of the commonest disease problems of the modern swine industry. The term enteritis applies to any inflammatory condition of the small intestine, but is used frequently to refer to any pathological condition of the digestive tract. The phenomenon, which is the common sequel to different kinds of adverse stimuli is an inflammation of the mucous membrane of the gastro-intestinal tract. Diarrhea which is a symptom, rather than a disease by itself, is a consequence of the inflammation of the alimentary tract brought about by any type of irritant of chemical, dietary, or microbial origin. Specific microorganisms are … Lire la suite

1962 — Angiotensin blood levels in man.Résumé
The problem of human arterial hypertension has been one of the most debated subjects in modern medicine. Many groups of investigators and clinicians have been interested in its etiology, its physiopathology and its treatment. The first suggestion that the kidneys might be responsible for this disease entity came from Richard Bright in 1836,and it was the result of a remarkable clinical acumen. In 1898, Tigerstedt and Bergman injected crude saline extract of rabbit kidney into anesthetized rabbits and observed a prolonged rise in blood pressure; they named this unknown pressor principle “rennin”.

1962 — Sorel and French radicalism.Résumé
The general state of Marxist thought at the turn of the century is examined as historical background against which to relate Sorel's theory of syndicalism. Basic premises of syndicalism are analyzed and compared with contemporary socialist interpretations of class struggle and social revolution. The comparison demonstrates a substantial disparity of approach to these two problems. Theoretical links between Sorel's views and principles of collective anarchism are discussed. Considerable similarity is found between Bakunin’s and Sorel's approaches to political solutions and Proudhon's and Sorel's views on moral issues. Lire la suite

1962 — The oceanography of Lancaster Sound.Résumé
The oceanographic regime of Lancaster Sound displays characteristics of two distinct water masses. The upper layer is physically similar to that encountered in the Arctic Ocean and is typical of conditions recorded in M'Clure Strait and on the Arctic continental shelf. Below the depth of 200 metres, water characteristics are identical to those observed in Baffin Bay. Baffin Bay water intrudes into Lancaster Sound and is defined as far west as Prince Regent Inlet. Analyses, using two T-S techniques, are carried out to show that water of Baffin Bay characteristics occurs at all sampling positions below 250 metres in the … Lire la suite

1962 — Danish - Scottish relations 1513-1542.Résumé
The year 1513 saw two new monarchs ascend the thrones of their ancient kingdoms. In spite of the five hundred miles of ocean which separated them, the difference of age, and of experience, they were to find much in common between themselves and between their realms. James V, King of Scotland, was an infant of one year in his nursery among the bleak dark walls of a Scottish castle. Faction and jealousy surrounded this infant whose father, James IV, had been killed on the blood-soaked field of Flodden. Lire la suite

1962 — The Canadian general election of 1908.Résumé
This thesis is a purely historical work which attempts to understand the basis of the political behaviour of Canadians in the General Election of 1908. The election was in many ways unique in that no issue of national interest was convincingly brought before the electorate. The electoral battle hinged therefore, not so much upon the subjects debated in Parliament and in the press but upon local, provincial, and regional considerations. The first four chapters investigate the background of the 1908 campaign, analyzing the position of the two political parties and examining the outstanding political issues of the years which immediately … Lire la suite

1962 — Some factors influencing the turbidity of water collected by river intakes.Résumé
In view of the apparent conflict of the results obtained by Messrs. R. J. Lindsay and V.A. Vanoni, and especially taking into consideration the probable errors which are relatively large when compared to the variations in turbidity determined, it was concluded that future investigations should be carried out in such a manner as to reduce the probable errors to a minimum. Since the research of R. J. Lindsay was directly concerned with water intakes, and since his conclusions were based on a great many more observations than those of Mr. Vanoni, it may be assumed that his conclusions are more … Lire la suite

1962 — The design and construction of a linear electron accelerator.Résumé
A linear electron accelerator, intended for radiotherapy and for physics research, has been built for the Royal Victoria Hospital. The electron energy (8.5 Mev) and peak beam current (>200 ma.) meet the design specifications. The design and construction procedures are described, and the techniques and results of various performance tests are given. A simplified explanation of magnetron frequency skipping, ascribed to long-line effect, is given. The thesis appendix gives a discussion of transverse accelerator orbits, and describes an approximate method of evaluating the required focusing field. Lire la suite

This is a etudy of one effect of the paid employment of the mother on one aspect of family relationships. It is intended to discover whether the mother 1s paid employment has any affect on decision-making in the home. (It is suggested that perhaps the working mother makes more decisions in the home and arrives at these more independently of her husband than her nonworking counterpart. ) [...] Lire la suite

1962 — Decision sequences in perception.Résumé
This study was undertaken to investigate the relation between preliminary and final perceptions, or decisions. The problem arose initially through an interest in the process of personnel selection, but is here extended to the perception of persons and objects generally. The question of the influence of preliminary decisions in personnel selection was raised through consideration of a study by Springbett (1954, 1958). In that work, interviewers recorded their impressions of applicants at intervals before the completion of the selection procedure, that is, before all information about the applicant had been introduced.

1962 — Effect of insulin on hepatic production and peripheral utilization of glucose in normal human subjects; studies with C14-glucose.Résumé
Almost forty years have elapsed since the discovery of insulin by banting and best, but its mechanism of action is still far from being completely elucidated. Although the number of relevant publications is steadily increasing, up to the present date no unanimity of scientific opinion exists as to the site of insulin action. Two opposing concepts emerged as a result of investigations. One group of workers considered that the main factor in causing hypoglycemia is the effect of insulin to increase the rate of glucose utilization another school of thought attributed the blood sugar lowering action of insulin to an … Lire la suite

1962 — The nature of non-precipitating antibodies.Résumé
The continuous formation of antibodies over long periods of time after immunization of animals with certain toxoids and bacterial polysaccharide (1, 2), dextran and blood group substances (3), and viruses (4), is well documented. More recently, antibodies of the nonprecipitating type have been shown to persist in the circulation of rabbits following immunization with serum protein antigens (5). In a previous study, it was shown that the non-precipitating antibodies could not be differentiated from the precipitating antibodies on the basis of their electrophoretic, sedimentation and salting out properties (6), although it was demonstrated that they, unlike the precipitating type, could … Lire la suite

1962 — Albedo measurements over sub-arctic surfaces.Résumé
During the summer months of 1961, measurements of the albedo of sub-Arctic surfaces in the Labrador-Ungava peninsula were undertaken. From chartered aircraft the parameter was measured over the major vegetarian cover-types previously studied and classified by a group of McGill workers. Ground measurements of albedo were also undertaken. A description of the instrumentation and its problems is presented in Chapter II. In Chapter III the flight coverage of the peninsula in relation to the vegetation cover-types is discussed. Chapter IV discusses the representative values of albedo together with the phenomenon of different albedo values under direct or diffuse solar radiation. Lire la suite

1962 — The isolation and structure of xanthomegnin.Résumé
Xanthomegnin is one of the pigments that were isolated from the mycelium Trichophyton megnini. It is a binaphthoquinone consisting of two identical moieties joined at the 3-position (I). Analytical data and spectral studies established the formula as (C15H11O6)2. The monomeric unit has one methoxyl, one hydrogen bonded phenolic hydroxyl, a CH3-CH(-O-)-CH2-Ar group, and one aromatic proton. Reduction gave a hydrogen-bonded quinol, as evidenced by the lowering of the absorption band of the carbonyl from 1716 cm-1 to 1658 cm-1. This carboxyl is part of a lactone group, since the barium salt of the pigment exhibited bands typical of a carboxylate … Lire la suite

1962 — Immunologic studies on ragweed allergy.Résumé
The word "allergy" was first used by Von Pirquet (1) to describe "changed or altered reactivity" to various agents and included immunity as well as hypersensitivity. To-day, however, it is used most often as a synonym of hypersensitivity. (2) and is defined by Sherman and Kessler (3) as "a general term to include all of the phenomena of specific sensitization believed to be mediated by an antigen-antibody mechanism. Certain clinical forms of allergy, like hay fever and asthma, seem to be determined partly by hereditary influences and for these Coca and Cooke (10) in 1923, proposed the word "atopy" (from … Lire la suite

1962 — Influence of certain climatic factors on the varietal adaptation of oats.Résumé
The 1956 acreage of oats in the province of Quebec was estimated at a little over one million three hundred thousand acres, representing approximately eleven per cent of the total Canadian oat acreage. Thus, among field crops, oats come second only to hay crops for both the acreage covered and the total farm value of the produce. Oats are grown on a wide variety of soils and under a broad range of climatic conditions, from the warm summers of the Ottawa-Montreal plain to the shorter and colder seasons of Lake St. John and Northwestern Quebec. The importance of the crop … Lire la suite

1962 — Monolayer film characteristics of some chain substituted derivatives of stearic acid.Résumé
A study of the mechanical and electrical properties of unimolecular films of some chain substituted stearic acid derivatives forms the subject matter of the investigation reported in this thesis. Experimental studies have been made of the surface potential and surface pressure of monolayers at four temperatures and two different rates of compression. The phenomenon of monolayer surface pressure relaxation has also been investigated. The effect of the nature of the substrate and the presence of polyvalent metallic substrate ions on the pressure-area isotherms of the monolayers has also been examined. Lire la suite
