We present a numerical method for the investigation of quasiperiodic oscillations in applications modeled by systems of ordinary differential equations. We focus on systems with parts that have a significant rotational speed. An important element of our approach is that it allows us to verify whether one can neglect gravitational forces after a change of coordinates into a corotating frame. Spe...

This morning, we have just heard Malcolm Knight speak about the remarkable and equally dynamic evolution taking place in accounting, fuelled by convergence trends within banking, between banking and insurance and across global markets. I’m pleased that my remarks today will echo many of these same thoughts, and that the topics chosen for our workshops will focus on some of the key issues we sup...

Introduction Studies a ssessing the d iametr ic dimensions of apical anatomy repeatedly demonstrate that the bucco-lingual diameter is greater than the mesio-distal diameter— canals are predominantly ovoid throughout, not round (Figs. 1a and 1b). The technical flaw most inherent—the use of a round file of any design to clean an ovoid canal configuration —manifests as the failure to debride a su...

The aim of this paper is to introduce a theoretical model that distinguishes be­ tween concept and percept formation in object relations theory. The differ­ entiation between concept and percept formation has not been emphasized in the writings of the major object relations theorists in the United States during the past decade (Kohut, 1971; Kernberg, 1975; Masterson, 1981); and prior to this ti...

[1] Most estimates of diffusive flux (F) of methane (CH4) and carbon dioxide (CO2) from lakes are based on single-point flux chamber measurements or on piston velocity (k) modeled from wind speed and single-point measurements of surface water gas concentrations (Caq). We analyzed spatial variability of F of CH4 and CO2, as well as Caq and k in 22 European lakes during late summer. F and k were ...

This paper explores the possibilities and limits of a discourse grammar applied to spontaneous speech. Most discourse grammars (e.g. SDRT, Asher, 1993; RST, Mann & Thompson, 1988) tend to be descriptive theories of written discourse which presuppose a coherent structure. This structure is the outcome of a goal directed planning process on the part of the producer. In order to obtain a better un...
