Implications of space radiations in manned space flights.
T H A T ionizing radiations produce deleterious biological effects 'has ,been proven by sixty years of experience and experimentation. Qualitatively, the effects of all ionizing radiations, whether they are gamma rays or heavy primary cosmic parti.cles, are the same and are a manifestation of the ionization produced in cells and tissaes,. Quantita~tivety, the effects are dependent on quality an...
متن کاملOxygen 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 کاملRadiation Hazards and Manned Space Flight.
T HE POTENTIAL medical hazards of man's venture into space will span a number of disciplines in regard to the pathology and deranged physiology to which the human body may be subject in travel beyond the earth's atmosphere. Not the least hazard is that having to do with the effects of radiation to be encountered in free space. This problem is one which is receiving considerable attention from a...
متن کاملUtilization of Intelligent Systems Technologies for Manned Mission Operations Support
With the International Space Station being extended to 2020, there is additional emphasis in the manned spaceflight program to find more efficient and effective ways of providing the ground-based mission support. This search for improvement has led to a cross-fertilization between the advanced software development community and the manned spaceflight operations community. Many mission operation...
متن کاملFeasibility of Polysulfone as Base Polymer in a Polymer Inclusion Membrane: Synthesis and Characterisation
Polysulfone was investigated as an alternative base-polymer for polymer inclusion membranes (PIM’s) that could withstand harsh environmental conditions and have good transport efficiency of metal ions. PIM’s were prepared using polysulfone as a base polymer and Aliquat 336 as a carrier in the absence of a plasticizer. Chromium (VI) was used as standard to study the extraction efficiency of the ...
