Abstract: A slip control method controls slip of the driving wheels of a vehicle. The method includes detecting excess slip of the driving wheels of the vehicle during acceleration, and reducing a driving force to said driving wheels upon detection of said excess slip in order to limit the slip of the driving wheels. The slip control of said driving wheels is inhibited upon detection of the application of a parking brake of the vehicle, or upon the detection of the transmission of the vehicle as being in the reverse gear position.

Abstract: Compounds of the formula: ##STR1## wherein W is selected from the group consisting of ##STR2## Wherein Q is hydrogen or --CH.sub.2 OR.sup.1 ;Z is hydrogen or --OR.sup.1 ;n is 1 or 2;wherein R.sup.1 are the same or different radicals selected from the group consisting of hydrogen, and ##STR3## where R.sup.2 is lower alkyl, aryl, or aralkyl; wherein the bond at positions 2' and 3' of structure I may be single or double; or it may be a C-nucleoside attached at 3' position of the sugar; X and Y are the same or different selected from the group consisting of hydrogen, an electron withdrawing group, and a group wherein X and Y taken together form a 6-membered carbocylic aromatic ring, are useful as radiosensitizing agents during x-ray radiotherapy of tumor cells.
