Introduction,e time. The mathematical theory for this is extensive and reviews may be found in Levine (1990) and Samarskii .. (1994). However, finite time blow-up and other very rapid instabilities occur in situations in mechanics and other areas of applied mathematics, and studies of these phenomena have very rInsensate 发表于 2025-3-27 04:13:39
Analysis of a First-Order System,ramifications of these which arise in various thermal convection contexts. In addition to studying blow-up (or non-existence) we also examine when the solution will remain bounded for all time, or even decay. The study of the system is of interest in its own right, and we have not seen this particulMOT 发表于 2025-3-27 05:43:54

Blow-Up in Volterra Equations,ion, or of a solution to a system of such equations. Roberts .. (1993) investigated a single Volterra equation with the underlying spatial domain being the whole of the real line, and the study of the asymptotic behaviour of their solution was extended by Roberts & Olmstead (1996).

Chemotaxis,pulation of a biological species. In a diffusion process, if the species is densely crowded together then diffusion acts to spread the population outward in space. Chemotaxis is a completely different effect whereby the species is attracted towards a high chemical concentration. For example, as Murr分期付款 发表于 2025-3-27 20:20:51

Negotiating Assimilation and Hybridity: The Identity of Chinese-Malays in Brunei Darussalamth a relatively simple, non-invasive tool for visualizing myocardial perfusion. The accuracy of this test has usually been judged using coronary arteriography as the standard , although the latter measures coronary anatomy rather than physiology. This fact underscores the continued use of selectiCHANT 发表于 2025-3-28 13:48:29

The maximum of fluorescence also manifested itself in the cases when the cell densities in the layers of maximum if micro- and nanophytoplankton exceeded 10. cells per liter.
