But these patterns do not supplement, much less supersede, the fundamental interactions.
Manual "cordboard" operators, as they were called, were superseded less by the inventiveness of Bell Laboratories, as Mr. Homer maintains, than by competition from more advanced foreign-manufactured telephone systems.
Traditional harvesting, which was less efficient, was superseded by new, highly mechanized technologies of harvesting.
This operation, until 1943 the only large-scale method used, has been superseded by less expensive processes, such as fractional distillation (D2O becomes concentrated in the liquid residue because it is less volatile than H2O).
This system was introduced in the early 1950s by the American astronomers Harold Lester Johnson and William Wilson Morgan and has largely superseded the less accurate system using the north polar sequence.
There has never been commercial production of the metal, and, although its compounds were frequently used in the first half of the 20th century for cancer treatment, they have largely been superseded by less expensive alternatives.
Historically, the main use was as a raw material in the production of pigments for lead paints, but such paints have been superseded by less toxic paints based on titanium dioxide.
Scepticism about GDT may exist for a number of reasons: many of the studies performed may be considered outdated; the high mortality rates in some of the studies performed are not representative of current clinical practice; and pulmonary artery catheters (PACs) are used in many of the clinical trials but have been largely superseded by less invasive haemodynamic monitors.
The BCSB had been investigating all superseded accounts paying less than 3percentnt interest on balances of more than £5,000.
In most therapeutic applications, however, radium has been superseded by the less costly and more powerful artificial radioisotopes cobalt-60 and cesium-137.
Its properties as an anti-cancer agent were discovered more than 60 years ago; today, it has been superseded by newer, less toxic medicines, and it is a niche product, with sales of only $546,000 in 2004, according to IMS Health, a market research firm.
