We outline a new class of robust and efficient methods for solving the Navier -- Stokes equations. We describe a general solution strategy that has two basic building blocks: an implicit time integrator using a stabilized trapezoid rule with an explicit Adam -- Bashforth method for error control, and a robust Krylov subspace solver for the spatially discretized system. We present numerical experiments illustrating the potential of our approach.

Magnetotelluric exploration has shown that the middle and lower crust is anomalously conductive across most of the north-to-south width of the Tibetan plateau. The integrated conductivity (conductance) of the Tibetan crust ranges from 3000 to greater than 20,000 siemens. In contrast, stable continental regions typically exhibit conductances from 20 to 1000 siemens, averaging 100 siemens. Such pervasively high conductance suggests that partial melt and/or aqueous fluids are widespread within the Tibetan crust. In southern Tibet, the high-conductivity layer is at a depth of 15 to 20 kilometers and is probably due to partial melt and aqueous fluids in the crust. In northern Tibet, the conductive layer is at 30 to 40 kilometers and is due to partial melting. Zones of fluid may represent weaker areas that could accommodate deformation and lower crustal flow.

There appears to be a growing consensus among those engaged in research in the international organization field that regional integration has been the most stimulating area of research for the last ten years because of the conscious efforts of the major theorists in this area to develop and test hypotheses concerning the dynamics of organizational development. There is consensus also that the rest of the field could profit by developing a more conscious concern with the dynamics of organizational development. Robert O. Keohane’s “Institutionalization in the United Nations General Assembly” represents a substantial attempt to provide the framework for a model of organizational development applicable to the United Nations.

The fifteenth session of the General Assembly of the United Nations which convened in New York in September 1960 marked an important turning point in the history of the Organization. The United Nations had been created primarily through the efforts of states with a European or European-derived political and social culture possessing a common history of political involvement at the international level. During its first ten years the Organization was dominated by the problems and conflicts of these same states. However, by 1955 the process of decolonization which has marked the post-1945 political arena began to be reflected in the membership of the United Nations. In the ten years preceding the end of 1955 ten new nations devoid of experience in the contemporary international arena and struggling with the multitudinous problems of fashioning coherent national entities in the face of both internal and external pressures joined the Organization. By 1960 the rising tide of decolonization had reached flood crest with the entry in that one year of seventeen new Members—sixteen of which were from Africa.

Consumer research is best conducted in stores, showrooms, shopping malls and restaurants because these are where consumers usually make their purchase decisions. In on-site consumer research, the customers are given time to engage in an actual, real-time eating/shopping/buying/browsing activity before they are approached by the researchers to request for an interview. Shoppers, travelers and restaurant patrons are most influenced by the details and they can better remember and discuss these details during real shopping, eating and traveling experiences. The five types of interviews that can be used for on-site consumer research are stream-of-consciousness interview, spontaneous reaction interview, directed general response interview, directed specific response interview and prompted reaction to execution elements.
