Abstract: A downhole cutting tool includes a tool body and a plurality of cutter knife sets, each of the plurality of cutter knife sets configured to extend outwardly to separately perform a pipe cutting operation. A first cutter knife set has a diameter in an extended position larger than a diameter in an extended position of a second cutter knife set. A method includes running the downhole cutting tool into a wellbore, deploying the first set of expandable cutting arms to an extended position and engaging the extended expandable cutting arms with a first work piece, rotating the downhole cutting tool and cutting the first work piece, deploying the second set of expandable cutting arms during a single trip into the wellbore to an extended position and engaging the extended expandable cutting arms with a second work piece, and rotating the downhole cutting tool and cutting the second work piece.

Abstract: A downhole pipe cutting tool includes a tool body having a piston assembly disposed in a central bore thereof, wherein the piston assembly is configured to translate longitudinally along the central axis of the tool body, and a plurality of cutter knife sets. Each of the plurality of cutter knife sets includes at least two individual cutter knives circumferentially spaced about a central axis of the tool body and is configured to selectively engage with the piston assembly to extend outward to perform pipe cutting operation.

Abstract: A method for preventing medical device-associated microorganism infection includes the steps of providing a medical device and incorporating an effective amount of an oxazolidinone compound, such as linezolid, into the medical device.

Abstract: The present invention teaches that cognitive skills may be trained by methods of increasing loading, distraction and pace while a trainee is carrying out a cognitive skill related repetitive mental task. Loading may comprise addition of a second repetitive mental task, distraction may be visual, auditory, kinesthetic and may increase in the power of the distraction, and pace may be increased until a maximum pace is achieved. Patterned, continuous, intermittent, and combined loading, distraction and pace changes may be used, as well as patterned feedback. The result is that the student learns to process the stimuli—using the cognitive skills—at increased levels of efficiency and speed.

Abstract: Compounds of formula (I) and pharmacologically acceptable salts thereof wherein: n is 1 to 3, R is an alkyl, R.sub.1 is hydrogen or alkyl, R.sub.2 is alkyl, R.sub.3 is an alkyl; b) alkyl substituted with an aryl, heteroaryl or cycloalkyl; c) alkyl substituted with one to eight fluorine atoms; d) cycloalkyl; e) alkenyl; f) alkyl substituted with one to three hydroxy, acyloxy or alkoxy substituents, and where the sum of carbons in R.sub.2 and R.sub.3 is greater than five br where R.sub.2 and R.sub.3 with the nitrogen atom form a saturated heterocyclic group having one nitrogen and form 4-8 carbon atoms or a 4-substituted piperazine group in which the 4-substituent can be alkyl, aryl, benzyl, or heteroaryl, and X is hydrogen, hydroxy, alkoxy, alkyl, carbon trifluoride or a halogen, or compounds of formula (I') and pharmacologically acceptable salts thereof wherein: n is 1 to 3, R is an alkyl, R.sub.1 is hydrogen or alkyl, R.sub.2 is an alkyl, R.sub.

Abstract: Methanesulfonamides are structurally depicted by Formula I' ##STR1## or its pharmacologically acceptable salts where R.sub.3 is a C.sub.1-7 alkyl substituted with C.sub.3-7 cycloalkyl, or a C.sub.1-10 alkyl substituted with one to eight fluorine atoms, one to three hydroxy, one to three C.sub.1-5 acyloxy or one to three C.sub.1-4 alkoxy substituents. These compounds are useful as Class III antiarrhythmic agents and are stable against rapid metabolism. Methods for treating cardiac arrhythmias with the compounds of Formula I' as well as compositions thereof are also described.

Abstract: Heat-softened glass sheets may have sharp bends imparted thereto by pressing between complementary molds when preceded by localized heating along the intended line of the sharp bend. The localized heat is applied along the line by means of electrical resistance heating through the glass immediately prior to the pressing step.
