Investigations of upper atmospheric processes are aimed at producing a realistic model of the atmosphere. Of primary importance in producing a model atmosphere is a knowledge of the rate constants of the possible reactions which can occur. Equally important is…

Studies were made to elucidate the pathways involved in the synthesis of phenazine pigments produced by Pseudomanas species. Iodinin, phenazine-1-carboxylic acid, oxychlororaphine and pyocyanine, though structurally related, have different biosynthetic pathways. The following observations related to these studies constitute a…

The volume of literature on the morphology and physiology of the vasculature is enormous. The concepts of the structure and activity of the blood vessels have changed greatly in the post fifteen years with the availability of revolutionary tools such…

Utilizing non-metabolizable substrates as valuable tools to differentiate between transport and subsequent metabolism, the possibility was explored whether there was a relationship between the sodium requirement by marine bacterial cella for growth and a sodium requirement for uptake of substrates.…

With the rapid increase in human population during recent years, a growing interest has developed in the resources of the sea. Although much basic knowledge has accumulated concerning the life in temperate and boreal waters, particularly of the eastern Atlantic,…

There is a region of the upper atmosphere called the mesopause which currently excites much interest. This region lies approximately between the altitudes of 80 and 90 kilometers. Today, knowledge of conditions in this region is necessary to predict satellite…

Present day knowledge of soil strength is limited to conditions favouring static or quasi-static loading. Under these conditions, the shear strength parameters are as yet not well defined. Neither is there satisfactory agreement on the true mechanism of friction and…

The use of authority in casework often presents a problem for the social work practitioner because of the great emphasis in the profession on client self determination. At times, a discrepancy arises between this principle and what is therapeutically indicated…

The purpose of this thesis is to outline a framework of analysis for the study of foreign policy and to apply this framework to an analysis of the factors shaping the foreign policy of the People's Republic of China. There…

In recent years our knowledge of ore deposits, and of the conditions under which they were deposited, has been augmented by experimental investigations of sulphide, and to a lesser extent, arsenide, oxide, selenide, and telluride systems. The physical conditions of…
