    Clonal Variation in Total Nonstructural Carbohydrates of Trembling Aspen Roots in Three Utah Areas (1971)
    Canadian Science Publishing
    Details
    Publication Date: 1971-12-01
    Description: Root samples collected from trembling aspen (Populustremuloides Michx.) clones after leaf-fall at three Utah locations were analyzed for total nonstructural carbohydrates (TNC). TNC were removed from root tissue by a takadiastase enzyme method rarely used in the study of tree physiology. Differences in TNC percentages among clones within areas appeared to be genetic. Age and site were additional factors causing differences among areas.

    Prolonged weightlessness and calcium loss in man (1979)
    In:  Other Sources
    Details
    Publication Date: 2011-08-24
    Description: Data have been accumulated from a series of studies in which men have been subjected to weightlessness in orbital space flight for periods of up to 12 weeks. These data are used to predict the long term consequences of weightlessness upon the skeletal system. Space flight induced a loss of calcium which accelerated exponentially from about 50 mg/d at the end of 1 week to approx. 300 mg/d at the end of 12 weeks. The hypercalciuria reached a constant level within 4 weeks while fecal calcium losses continued to increase throughout the period of exposure. This apparent diminution of gastrointestinal absorptive efficiency was accompanied by a slight decline in the plasma level of parathyroid hormone and a slight elevation in the plasma level of calcium and phosphorus. Although losses in mineral from the calcaneus were closely correlated with the calcium imbalance, no changes were detected in the mineral mass of the ulna and radius. From the data presented it is concluded that the process of demineralization observed in space flight is more severe than would be predicted on the basis of observations in immobilized, bed rested, or paralyzed subjects. It is, moreover, suggested that the process may not be totally reversible.

    Engineering and simulation of life sciences Spacelab experiments (1979)
    In:  Other Sources
    Details
    Publication Date: 2011-08-24
    Description: The third in a series of Spacelab Mission Development tests was conducted at the Johnson (correction of Johnston) Space Center as a part of the development of Life Sciences experiments for the Space Shuttle era. The latest test was a joint effort of the Ames Research and Johnson Space Centers and utilized animals and men for study. The basic objective of this test was to evaluate the operational concepts planned for the Space Shuttle life science payloads program. A three-man crew (Mission Specialist and two Payload Specialists) conducted 26 experiments and 12 operational tests, which were selected for this 7-day mission simulation. The crew lived on board a simulated Orbiter/Spacelab mockup 24 hr a day. The Orbiter section contained the mid deck crew quarters area, complete with sleeping, galley and waste management provisions. The Spacelab was identical in geometry to the European Space Agency Spacelab design, complete with removable rack sections and stowage provisions. Communications between the crewmen and support personnel were configured and controlled as currently planned for operational shuttle flights. For this test a Science Operations Remote Center was manned at the Ames Research Center and was managed by simulated Mission Control and Payload Operation Control Centers at the Johnson Space Center. This paper presents the test objectives, description of the facilities and test program, and the results of this test.

    Crew and life support: EVA (1984)
    In:  CASI
    Details
    Publication Date: 2006-04-03
    Description: Four general recommendations by the EVA subpanel are listed as follows: 1) EVA design standard document needs to be dveloped in the next 6 to 12 months and updated as technology progresses. 2) NASA needs to couple EVA design personnel closer to the user community. 3) there appears to be a lack of centralized NASA responsibility for the EVA community. 4) Panel activity should continue to promote exchange of information and understanding of user problems, and to stimulate technology activity.

    The lunar quarantine program (1974)
    In:  CASI
    Details
    Publication Date: 2006-01-12
    Description: The lunar quarantine program was designed to ensure that return of lunar material represented no threat to the public health, to agriculture, or to other living resources. It established definitely that no life exists on the moon. The crews of the three lunar quarantine missions, Apollo 11, 12, and 14, experienced no health problems as a result of their exposure to lunar samples. Plants and animals also showed no adverse effects. Stringent quarantine was terminated after Apollo 14, but lunar samples continued to be protected to guarantee that scientists would receive uncontaminated materials for study.

    Details
    Publication Date: 2006-01-11
    Description: The objective of the Skylab medical experiment altitude test was to provide a nearly full scale simulation of a 56-day Skylab mission for studying physiological changes produced in man by the long term exposure to space conditions. Evaluated in the altitude chamber tests were human cardiovascular/hemodynamic responses, musculoskeletal/metabolic effects, endocrine/electrode factors, and neurophysiological indices.
