A support member for supporting a roof of a subsurface space. This opening is necessary to replace an aging nuclear reactor with a new, safer and more efficient reactor. The card application has only to carry out the same operation as data exchange with a related dedicated host terminal. In still other embodiments, the adaptive control scheme is used with a constant adaptation matrix, whereby a value of is statically calculated. In some embodiments, the word-processing application is launched from a case-management application that provides case, activity, and role information to the online legal research system.
