Time has not been kind to Great Britain's intervention in the Spanish civil war of 1834 to 1840. An examination of histories, biographies and memoirs published since about 1840 yields surprisingly little in the way of information or comment. Although there are a few important works which deal with this problem, they do so incompletely. [...]  Lire la suite

From the 1790 's, when Galvani and Volta (R. M. Green, 1953) experimented with animal electricity, until the beginning of the 20th century, there was little reason to doubt that excitation passed from nerve to muscle electrically (Kuhne, 1888). Protoplasmic continuity was assumed, despite increasing evidence to the contrary, until about the turn of the century. [...]  Lire la suite

Simple moment strain relations are derived which predict with acceptable accuracy the forces required to bend thick plates to cylindrical surfaces, using methods employed in the pressure vessel industry.  Lire la suite

During the early months of 1965, the prolonged and contentious debate concerning constitutional amendment in Canada seemed to be drawing toward a satisfactory and definitive conclusion. Federal authorities had succeeded in preparing an amending formula acceptable to all the provincial governments, and with this formidable hurdle finally surmounted, the drive to "re-patriate" the constitution seemed to be assured of success.

The enzymology of the adrenal gland, in sharp contradistinction to its histology in most species, has remained, until recently, neatly demarcated in two independent fields, without the slightest tangential contact: the cortex, containing a battery of highly specific enzymes operating sequentially upon substrates to produce the physiologically active corticosteroids, and the inner portion of the gland, the medulla, with an equally specific group of catalytic agents attacking exclusively those substrates involved in the elaboration of catecholamines.

A chemical transport reaction is a reaction taking place between a non-volatile solid and a transporter gas, in which intermediate volatile compounds are formed; these gaseous compounds move to a different part of the system where they react ad result in the reformation of the original solid material.

Since the cortex is the highest integrating center in the mammal and the most accessible, it is natural that it should have been the object of much experimentation. One way of investigating the functions of the cortex is to remove it entirely, and study the behavior of the decorticate animal. [...]  Lire la suite

The rise of Existentialism in the 20th century has engendered mixed reactions in the minds of most critical observers of the philosophical scene. Some have tended to dismiss it lightly as a passing phase, comparing it, for example, to the post-World War I cult of dadaism. They regarded it as a mere product of the times which was bound to pass away as times changed. [...]  Lire la suite

Martinique became a full overseas department of France in 1946 (27:802), and Saint Lucia will soon change its status from a BritiSh colony to an independent Caribbean nation. Such political changes indicate that these small islands must rely ever increasingly upon their own resources to satisfy their needs. [...]  Lire la suite

It is recognized that there are basically three categories of stability: Laplace, Liapunov, and Poincaré. It is difficult to say which concept is 'better'. This will depend on our requirements on the solutions themselves. [...]  Lire la suite

Selye was the first to show that apparently unrelated, non-specific stimuli, termed "Stressors", challenge the body's tendency to maintain homeostasis and trigger a sequence of physiological events which are attributed to the actions of adrenocorticotrophin (ACTH)(l)(2). The actions of ACTH include eosinopenia, involution of the lymphoid tissues, the enlargement of the adrenal cortex with the synthesis and release of adrenocortical steroids and the depletion of adrenal cholesterol and adrenal ascorbic acid (2).

This investigation is designed to elucidate the influence of surface charge of fibres upon flocculation of the fibre suspensions. To achieve this goal, experiments to measure the flocculating tendency and the surface charge of the fibre networks were consecutively performed on the same sample of fibre suspension. Electrolytes of various ionic species and different concentrations wre added to the supensions, and the effects on the corresponding properties were observed. [...]  Lire la suite

Water in clay soils is considered to be held by capillary and swelling forces. Both forces are operative but the importance of each force depends upon the water content. This relationship was assessed from water retention, swelling pressure, and volume change studies using samples of different aggregate sizes compacted to different porosities. [...]  Lire la suite

Milk was collected from five Rocky Mountam bighorn sheep living in the Jasper National Park area of Alberta. The milk was collected at 1 1/2 and 3 months post partum. The total solids, ash, fat, lactose and protein contents of the five samples were determined. The fatty acids constitution of the milk fat was estimated by gas-liquid chromatography.

The elastic and plastic behaviour of a wide-flange beam with a large extended opening in the web is investigated theoretically and experimentally for various loading conditions. Two different methods are introduced for calculating the elastic stresses at the boundary of the opening for pure bending and for pure shear. [...]  Lire la suite

Because of a lack of fossil evidence of the evolutionary development of the flower, our understanding of its structure is derived almost entirely from comparative studies of morphology, anatomy, ontogeny and histogenesis of existing floral types. Morphology has often been considered by others as a thoroughly explored field. This opinion may be correct as far as the study of external forms is concerned, but unlikely so in the studies of floral ontogeny or developmental morphology. [...]  Lire la suite

A radar study of two Alberta hailstorms has revealed the existence of small cellular radar echoes with durations of 10-30 minutes. These cells were found to group together to form storm families which existed for several hours. New cells invariably formed on the southern end of the storm family and migrated northward through the storm to dissipate on the northern boundary. [...]  Lire la suite

Mean evaporation patterns are presented for cyclones and for anticyclones. From these patterns it is deduced that the rate of evaporation is higher under cyclonic circulation than under anticyclonic circulation. The seasonal variation in the rate of evaporation is analyzed. [...]  Lire la suite

In chemical industry as well as in nature, one encounters numerous situations in which there is intimate contact between a finely sub-divided solid or a liquid-dispersed phase and a continuous fluid phase. This phenomenon occurs primarily in moving liquids or gaseous media and is being increasingly encountered in practical engineering applications, such as solids-gas contacting operations, spray processes, air pollution control and the design or solids-burning rocket engines.

A considerable number of littoral and shallow water marine molluscs from the West Indian region and other areas reached Europe during the second half of the eighteenth and first half of the nineteenth century. These were, in many cases, brought by travelers and navigators and later described by European naturalists. Outstanding among these were Jean B. Lamarck, Carl von Linnaeus, J. F. Gmelin and Alcide d'Orbigny. Although they reported many species from the Lesser Antilles, very few are recorded from Barbados. [...]  Lire la suite

Velocity profiles of propeller and turbine type impellers were measured in both air and water using a hot wire anemometer probe, and two and three dimensional pitot tubes. These pitot probes were particularly suitable for this work, since they permitted the measurement of velocity and inclination of flow in the turbine jet, from which the radial and tangential velocity components were evaluated.

The collèges classiques have been the most noteworthy of French Canadian educational institutions. Yet there have been very few studies on the history of these schools in Canada in the French language, and none in English. Since there is a lack of such studies, particularly on the early period of the collèges classiques, it was deemed expedient that a survey of the origin and early development of these institutions be undertaken.

This project develops a method to enter graphical data into a digital computer. In the first phase of the project a device was built to read graphs and convert the graphical information into digital data of a form acceptable to enter a digital computer. In the second phase a computer program was prepared to manipulate the data. [...]  Lire la suite

Two points of view exist at present on how inference about the true number of factors should be made. In the older classical statistical approach the N individuals are considered as a sample from a population of individuals and an attempt is made to make inferences about this population from the characteristics of the sample. The proponents of the newer, psychometric approach consider the n variables as a sample from a universe of content and attempt to make inferences about this universe. [...]  Lire la suite

This is a study in supreme command, its nature and the course of its development within the fabric of the English Constitution during the decade or so prior to the shattering of the peace of the old world and the coming of the War in Europe. It is a study concerned with an examination of the formulation and development of defence policy only in so far as these factors helped determine the course and outcome of the struggle, which occurred during these years, to establish an effective form of supreme command.

Over the last twenty years or so, dairying has become the largest agricultural enterprise in Quebec. It has also become the most profitable, supplanting other less profitable farm enterprises. Dairying in Quebec has grown to the point where Quebec is now Canada's leading dairy province. [...]  Lire la suite

In the past two decades the physiological role of adipose tissue has been the subject of intensive research. Besides serving as an insulator and mechanical buffer its major metabolic function has been found to be the storage of triglyceride as a potential source of energy. Fat is a particularly dense form of stored energy. [...]  Lire la suite

Interest in the study of antiviral substances stems from the fact that classical chemotherapy as it is known in bacterial diseases has thus far not been successful in the field of viral diseases. However, any proven antiviral agent is a potential drug against virus infection. Although the ultimate goal of effective chemotherapy of virus infections may or may not be attained, information concerning such substances may provide clues to the nature of host-virus interactions and help to elucidate the patterns of the pathogenesis of virus diseases (Zimmermann and Schafer, 1960; Melnick and Rapp, 1965) and also to afford tools for …  Lire la suite

The role of the auditory efferent innervation is a subject of great current interest. Its function has been grossly defined as being inhibitory in nature. Detailed work as to its role and especially the role of the homolateral component of the Olivocochlear Bundle is under speculation and investigation by many workers. [...]  Lire la suite

It has often been suggested that the humid tropical environment is not very suitable for cattle raising. Gourou (35, pp. 53-54), a geographer, states that these "hot, wet regions" of the world are not naturally adapted to pastoralism, particularly because of the high incidence of disease and the poverty of grasslands deficient in leguminous species.

Atmospheric kinetic energy calculations at 500 mb are carried out for the tropical region 20N to 20S on a daily basis during the month of September 1957. The basic data consist of grid point values of wind direction and speed obtained from streamline and isotach analyses of the tropical charts. [...]  Lire la suite

This thesis is concerned with a study or the relationship between the client's 'time' and 'activity' orientations and continuance and discontinuance in counselling after the intake interview at the Family Service Agency in Hamilton, Ontario. It was hypothesized that continuing clients would be 'future-active' or1entated, and discontinuing clients would be 'present-inactive' orientated. The 'time' and 'activity' orientations were struotured into six sub-topics; the client's view of the basie of his difficulty at intake, the service that he requests, his capacity to amass and use relevant faotual information, his capacity to admit the social worker to hia emotions, his confidence in …  Lire la suite

At the conclusion of the First World War, Great Britain ranked highest among the world's great maritime Powers, with a fleet materially enriched by the wartime construction of over fifteen hundred vessels and a naval establishment edified by its 1914-1918 experience in the use of the new Navy. Consequently, it was not apparent to other than the most astute observer that the Royal Navy had, in fact, reached the pinnacle of its ascendancy. [...]  Lire la suite

A simplified shell model calculation based largely on experimental information showed that an accidental cancellation occurs in the Gamow-Teller matrix element describing these decays, the transition probability being thereby decreased by two orders of magnitude. [...]  Lire la suite

It has long been considered that the best way to study certain physiological aspects of insects such as their nutrition and response to various host plants would be to develop aseptic synthetic diets. According to Friend (1958) such a diet should satisfy in its physical and chemical characteristics the insects requirements, be in an edible form, and contain the optimum amount of essential nutrients.
