Le but de ce travail est d'arriver à la détermination du niveau d'induction (de tension et de courant lorsqu'un contact au sol est établi) sur un objet placé dans le champ électrostatique d'une ligne triphasée à très haute tension. Cet objet peut être quelconque mais plutôt de dimensions finies, v.g. un camion ou une remorque, de sorte que l'étude est essentiellement à trois dimensions. Ceci d'ailleurs explique le fait qu'aucune étude théorique, à la connaissance de l'auteur, n'existe sur ce sujet. On connait bien le phénomène d'induction électrostatique sur un fil ou câble parallèle à une ligne sous tension lorsque …  Lire la suite

A system is described for time-lapse stereoscopic cloud photography using 16-mm cameras, for rectification of the photographs for camera tilt, and for analysing them to obtain cloud dimensions by superimposing the projected images of stereo-pairs on a gridded screen. A discussion of theoretical photogrammetry as applied to cloud photography, and an analysis of the system errors and measurement uncertainties are given. [...]  Lire la suite

Mowrer's (1947) and Spence's (1956) suggestion that classical conditioning may play a significant role in the acquisition and performance of instrumental responses has fostered two broad lines of research. One of these bas been concerned with the role of classcally conditioned responses in instrumental behavior (Wynne & Solomon, 1955; Solomon & Turner, 1962; Miller & DeBold, 1965; Williams, 1965) and bas produced mainly negative results. The proposition that the occurrence of certain classically conditioned responses (e.g., autonomic "anxiety" reactions, anticipatory goal responses, or rg) is an essential step in instrumental responding seems no longer tenable. The second line of research …  Lire la suite

[...] This thesis will be confined to a study of the benevolent gentlemen in Dickens novels, and will attempt to answer such questions as: Who were these men? For what purpose did Dickens create them? What function do they serve in the novels? How great, or how limited, is their scope of action? Did they provide Dickens with his ultimate answers to the problems of human behaviour? Chapter I will discuss the background, origin and characteristics of the benevolent gentlemen. Chapter II will describe the benevolent gentlemen of the early novels, Mr. Pickcwick (The Picknick Papers, 1836-37), Mr. Brownlow (Oliver …  Lire la suite

The Mattagami Lake mine deposit is a zinc and copper-bearing pyritiferous deposit emplaced in a thick volcanic pile at the contact of pyroclastic rhyodacite and effusive andesite. In its geological setting and mineralogy it is similar to many other deposits in North America, e.g. the Horne and Lake Dufault mines of the Noranda camp, flin flan, Geco mine, Buchans, the deposits of Shasta County, California and the Verde mine, Arizona. Comparable deposits are found in the Calidonides of Norway, in the Urals, Spain, Cyprus and Japan. [...]  Lire la suite

The first three cantos of the Book of Courtesy discover to us the realm of social relations, where, as in the sphere of Justice, a strict system of gradation operates. lndeed, Spenser, in the early part of Book VI, sustains much of the atmosphere of the "stonie" age of Book V, and Calidore's initial adventures illustrate the abuses to which a hierarchical order of society lends itself in the fallen world. The poet's artistic exploration of these abuses traces their origins to the mean and malicious impulses of the human mind, which are, in a larger context, manifestations of the …  Lire la suite

Leguminous seeds are generally highly nutritious and have been used in the human diet for many centuries. The peasants of Asia and elsewhere grow leguminous seeds on small plots of land for their own consumption. The seeds are allowed to dry in the fields and are stored for use throughout the year. Dried seeds are either ground finely for use in baking or the whole seeds are boiled and used to make soups and curries. It has been known for centuries that seeds of the same variety may display variation in their cookability. The producer of commercial pea soups today …  Lire la suite

The fertilized egg, in its development, may take one of three possible courses. It may develop normally; it may deviate from the normal course as the result of intrinsic or external forces to produce a congenital anomaly; or it may abort or resorb. In marnmalian systems the course of development is determined by the interaction between the fetal genotype and its environment. The fetal environment, which is its mother's uterus, is in turn determined by the interaction between the maternal genotype and environment. [...]  Lire la suite

[...] The aim of this work is twofold. Firstly, a tentatively critical review of the mechanisms involved in the regulation of vascular smooth muscle reactivity as a basis for an interpretation of the above mentioned phenomena will be made. Secondly, we shall present an account of our experimental approach to this problem involving "in vivo" and "in vitro" studies of vascular reactivity to angiotensin and norepinephrine in the rat.

[...] Calculations have shown that the resonance-dispersion analysis of experimental data, which is based on a two-level system, should yield single-valued relaxation times in the case of multi-level systems as well, and the results should be equal to those of pulse-saturation measurements where the return to equilibrium in the latter case can be characterized by a simple exponential.  Lire la suite

An interaction between nucleons and/or nuclei is commonly termed a nuclear reaction. This includes a variety of processes such as elastic or inelastic scattering, spallation, fragmentation, fission, etc. In the present work strontium, enriched to greater than 99.8% in mass 88, was bombarded with protons in the energy range 7 to 85 MeV. Elastic or inelastic scattering studies, although important, have not been undertaken in this work. The process of fission involves the division of target nucleus into two or more roughly equal masses; while in fragmentation, chunks of nuclear matter are split off from the struck nucleus. The chance …  Lire la suite

[...] This thesis presents an attempt to understand the experimental situation on the basis of an optical potential model. The theory of potential scattering, namely, the quantummechanical description of the collision of two particles interacting via a spherically symmetric potential, has been frequently employed as a model in arder to understand and investigate many physical ideas and dynamical properties in the realm of high energy physics. In particular, the study and physical interpretation of the analytic properties of relativistic scattering amplitudes in the energy, momentum transfer, and angular momentum variables was suggested or greatly assisted by the corresponding situation in …  Lire la suite

The aim of this thesis is to study the behaviour of the money supply of Trinidad and Tobago during the period from 1797 to 1964, and to relate it to the economic development of the country. No attempt will be made to discuss the implications of the Central Bank of Trinidad. The study ends at the time when the Bank was set up. In the course of the thesis I have described the capital market institutions and given a historical account of the development of the monetary framework of the economy. Both this, and the empirical analysis of the operations …  Lire la suite

[...] The existence of spin-dependent neutron-neutron, and neutron-proton interactions is well known. These are required to explain the properties of the deuteron, and the neutron-proton and neutron-neutron cross sections. The spins of the two nucleons are coupled by a tensor interaction. Thus, it seems reasonable to expect that the nucleon-nucleus interaction, in some average way, contains the spin-dependence of the nucleon-nucleon interaction. [...]  Lire la suite

Matching-to-sample usually involves the presentation of a stimulus, the sample, and several other stimuli, the matches, with the requirement that the subject find a stimulus in the latter array which matches the sample. ln visual matching-to-sample tasks the stimuli are often presented by means of a slide projector or card-changing apparatus, thus permitting the experimenter to control the duration and sequence of exposure. The subject indicates his choice by pointing to the matching stimulus, by pressing a pushbutton under the stimulus, or by pushing the stimulus directly to close a switch. [...]  Lire la suite

In early work this chemiluminescence was confused with that from the oxygen atom - nitric oxide reaction. Indeed it has turned out that their spectra and mechanisms are quite similar, so that an understanding of the 0-NO reaction (which was investigated first) will facilitate understanding of the O3-No reaction.

A method for obtaining proton-nucleus reaction cross sections from the elastic scattering data is described. The procedure involves the determination of the forward nuclear scattering amplitude from the elastic data and the calculable Coulomb scattering amplitude. The interference of the nuclear amplitude with the known Coulomb amplitude at small scattering angles makes it possible to determine both the magnitude and phase of the nuclear amplitude.

The aim of this thesis is to develop a theory of principal cofibre bundles which is dual in the sense of Eckmann-Hilton [3] to the theory of principal fibre bundles with a group G. If we take as definition of a fibration the homotopical definition of Serre or a similar definition there is a convenient dual notion of cofibration. [...]  Lire la suite

Whether a particular soil should be used for cropping, pasture, woodland or some other purpose, involves consequences which are far too important to be left to chance. Soil is a natural body having a specific morphology and in order to understand its behaviour as fully as possible, it is necessary to determine and to correlate its characteristics or properties under various sets of circumstances.

Stromatoporoids from the Esterhazy Shaft, Saskatchewan, collected from the Duperow formation (lower Upper Devonian), Souris River formation, First Red Bed and Dawson Bay formation (Middle Devonian) are found between depths of 1,987 feet and 3,058. 9 feet. [...]  Lire la suite

A pathogenic micro-organism does not always effect the host with the same intensity on all occasions. Not only the host but the entire biological complex influences the effectiveness of pathogens. There are many physical and biological factors which may contribute to this "differing response" and hence predispose a population to disease or resistance to disease. [...]  Lire la suite

During the past fifty years several investigators have attempted to develop a practical means of removing the retention products in cases of renal insufficiency. Three main methods have been investigated: (1) peritoneal lavage, (2) extracorporeal dialysis of blood, and (3) intestinal lavage, but there are few experimental studies to demonstrate the gastrointestinal excretion of creatinine.

The literature on the biology of Trichinella spiralis is full of many confusing and conflicting reports. The reviews of Reinhard (1958) and Schwartz (1960) of the early work on T. spiralis show that the unique character of the biology of this worm confounded the early workers, who attempted to unravel its entire life cycle.

The basic problem of the Calculus of Variations is that of finding a point in function space at which a given integral attains a maximum or a minimum value. The type of problem that can be solved by means of this calculus is referred to as a variational problem, and the extreme value of the integral is called an extremum. [...]  Lire la suite

The importance of fluorine in nutrition is related to its presence in small amounts in most foods and water supply and in all tissues of the body, particularly in bones and teeth. Throughout the 19th and early 20th centuries, fluorine was considered to be a poison. Scientific articles dealt with its toxic properties when used in preservatives and pesticides and with the ill-effects of extremely high concentrations of fluoride in drinking water and in industrial processing.

In the last decade geologists have made increasing use of phase equilibrium studies in synthetic systems to provide the fundamental data for the interpretation and understanding of the occurrence of minerals and mineral assemblages. The economic geologist has directed considerable study into the phase relations of the Fe-Ni-S system as a large number of the phases are found as minerals, which in some cases constitute important sources of nickel, iron and related metals.

An understanding of the total blood supply of malignant tumours is of fundamental importance not only to the surgeon interested in chemotherapy, but also to the radiotherapist and the medical oncologist. This is because the effect of cancericidal agents depends to a great extent upon the amount of agent delivered directly to the tumour cells within the tumour. [...]  Lire la suite

This is the first attempt to study the circumglobal pelagic planktonts of the Family Phronimidae collected from all oceans. Before Vosseler (1901) published his work on the systematics of the phronimid species, the sexual dimorphism and the age variation in these animals proved confusing to the taxonomists. Synonyms of the species were mostly made at this period. [...]  Lire la suite

In 1870 Canada completed the acquisition of Rupert's Land from the Hudson's Bay Company, and Manitoba entered Confederation as the fifth province. The Manitoba Act -- a law of the federal government, and the constitution of the new province -- established the official status of the French language in the Northwest, and continued the practice, begun by the Hudson's Bay Company's old Council of Assiniboia, of supporting from public funds separate Roman Catholic and protestant school systems.

During the summers of 1961 through 1964 field parties of the Geographical Branch, Department of Mines and Technical Surveys, conducted studies in the physical geography of north-central Baffin Island. While field research emphasized the glacial geomorphology of the area about the northwest margin of the Barnes Icecap, air photo interpretation over a much wider area revealed the existence of a series of major terminal and lateral moraines stretching for 640 km. (400 miles) in a belt roughly parallel to the heads of the Baffin Bay fiords (Map 1). [...]  Lire la suite

A distinctive feature of the chemical composition of the central nervous system is its high content of glycosphingolipids. The simpler members of this group, cerebroside, and cerebroside sulphate are found predominantly in the myelin sheath, and thus they may occur in greater amounts in glial cell membranes than in neuronal cell membranes.
