Oxygen recovery systems for manned space flight.
T H E PROBLEM of supplying man with his oxygen requirement and uncontaminated air during prolonged confinement is receiving considerable research attention. In particular, the recovery of oxygen using biological specimens as the mechanism for converting carbon dioxide into oxygen plus other materials has been the subject of many papers recently. There can be no doubt concerning the need for a r...
متن کاملMagnesium and Space Flight
Magnesium is an essential nutrient for muscle, cardiovascular, and bone health on Earth, and during space flight. We sought to evaluate magnesium status in 43 astronauts (34 male, 9 female; 47 ± 5 years old, mean ± SD) before, during, and after 4-6-month space missions. We also studied individuals participating in a ground analog of space flight (head-down-tilt bed rest; n = 27 (17 male, 10 fem...
متن کاملTuberculosis presenting as bronchoesophageal fistula
We report a case of bronchoesophageal fistula associated with tuberculosis. A 25 year old woman presented to us with 3 month history of cough worsening with deglutition. Radiological examination revealed mediastinal lymphadenopathy and bronchoscopy with esophagoscopy confirmed the presence of fistulous communication with features of endobronchial tuberculosis. Histological examination of bronch...
متن کاملMated Flight Control Issues for Space Exploration Systems
Several unique issues related to mated flight control have been broadly identified. These issues include redundancies in subsystems, controllability, command and control authority distribution, information flow across elements, and changes and variability in system characteristics due to variable mated configurations during operations. Architectural options for mated flight control are discusse...
متن کاملSpace Flight Studies
A standard rodent diet for space flight must meet the unique conditions imposed by the space environment and must be nutritionally adequate since diet can influence the outcome of experiments. This paper evaluates the use of National Aeronautics and Space Administration (NASA) developed Foodbars as a standard space flight diet for rats. The Foodbar’s semipurified formulation permits criteria su...
