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...

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...

The aims of this study were to describe body composition and physical fitness changes during a wholeseason in elite children tennis players. A total of 7 elite children tennis players participated in the study. Whole body composition by dual energy X-ray absorptiometry (DXA) and physical fitness were assessed during a season. Subjects increased lean and bone percentage, and decreased abdominal ...

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.

Introduction: Falls are considered as the major health problem in ageing and the damages caused by falls (such as fractures, disability, heavy costs on government and family, and death) are the major concern of the World Health Organization. So, determination of risk factors and specific ways to prevent falls in the elderlies are of great importance. The aim of this study was to evaluate the ef...

OBJECTIVE Surgery remains the treatment of choice in patients with potentially resectable lung carcinoma. Both the British Thoracic Society and American Chest Physician guidelines for the selection of patients with lung cancer surgery suggest the use of a shuttle walk test to predict outcome in patients with borderline lung function. The guidelines suggest that if the patient is unable to walk ...
