OBJECTIVE To determine if the metabolic cost of the incremental shuttle-walking test protocol is the same as treadmill walking or predicted values of walking-speed equations. SETTING Primary care (community-based cardiac rehabilitation). PARTICIPANTS Eight Caucasian cardiac rehabilitation patients (7 males) with a mean age of 67±5.2 years. PRIMARY AND SECONDARY OUTCOME MEASURES Oxygen con...

Die Shuttle-Heterodifunktionalisierungsreaktion, bei der zwei chemisch unterschiedliche funktionelle Gruppen zwischen Molekülen übertragen werden, war lange Zeit ein unerreichtes Ziel, da die Kontrolle Chemo-, Regio- und Stereoselektivität eine große Herausforderung darstellt. Wir präsentieren hier elektrochemische Shuttle-Reaktion (e-Shuttle), um selektiv RS- X-Gruppe β-Halogensulfiden ungesät...

In vitro reconstruction of the L-lactate/pyruvate shuttle has been performed, which allows NADH oxidation outside rat heart mitochondria. Such a shuttle occurs due to the combined action of the novel mitochondrial L-lactate/pyruvate antiporter, which differs from the monocarboxylate carrier, and the mitochondrial L-lactate dehydrogenase. The rate of L-lactate/pyruvate antiport proved to regulat...

BACKGROUND The relationship between the shuttle walk test and peak oxygen consumption in patients with lung cancer has not previously been reported. A study was undertaken to examine this relationship in patients referred for lung cancer surgery to test the hypothesis that the shuttle walk test would be useful in this clinical setting. METHODS 125 consecutive patients with potentially operabl...

In this paper analytical travel time model for the computation of cycle times and throughput performance of the multi-tier shuttle-based storage and retrieval system, is presented. The proposed model considers the real operating characteristics of the shuttle carrier and the elevators lifting table. Assuming uniform distributed storage locations and the probability theory, expressions for the e...

We report on a simple electromechanical memory device in which an iron nanoparticle shuttle is controllably positioned within a hollow nanotube channel. The shuttle can be moved reversibly via an electrical write signal and can be positioned with nanoscale precision. The position of the shuttle can be read out directly via a blind resistance read measurement, allowing application as a nonvolati...

This paper attempts to relate certain areas of similarity between Space Shuttle operation and Airline operation. The design controlled factors affecting airline maintenance cost are discussed. The thesis is that the Space Shuttle designer should consider airline experience in areas affecting maintenance cost in order to design the most cost effective Space Shuttle System.
