INTRODUCTION

This Supplement to Aerospace Medicine and Biology (NASA SP-7011) lists 238reports,articles and other documents announced duringDecemberil974inScientific and TechnicalAerospace Reports (STAR) or in International Aerospace A.bsracts l.,4 A . The first issue

of the bibliography was published in July 1964; since that time, monthly supplements havebeen issued.

In its subject coverage, Aerospace Medicine and Biology concentrates on the biological,physiological, psychological, and environmental effects to which man is subjected duringand following simulated or actual flight in the earth's atmosphere or in interplanetary space.References describing similar effects of biological organisms of lower order are also in-cluded. Such related topics as sanitary problems, pharmacology, toxicology, safety and sur-vival, life support systems, exobiology, and personnel factors receive appropriate attention.In general, emphasis is placed on applied research, but references to fundamental studies andtheoretical principles related to experimental development also qualify for inclusion.

Each entry in the bibliography consists of a bibliographic citation accompanied in mostcases by an abstract. The listing of the entries is arranged in two major sections: IA.AEntries and STAR Entries. in that order. The citations, and abstracts when available, arereproduced exactly as they appeared originally in IAA or STAR. including the originalaccession numbers from the respective announcement journals. This procedure, whichsaves time and money, accounts for the slight variation in citation appearances.

Two indexes-subject and personal author-are included.An annual index will be prepared at the end of the calendar year covering all documents

listed in the 1974 Supplements.

Microfiche (1 are available at the rate of$1.50 per microfiche for documents identified by the # symbol following the accessionnumber. A number of publications, because of their special characteristics, are availableonly for reference in the AIAA Technical Information Service Library. Minimum airmailpostage to foreign countries is $1.00. Please refer to the accession number, e.g.. A74-10763.when requesting publications.

STAR ENTRIES (N74-10000 Series)

A source from which a publication abstracted in this Section is available to the public isordinarily given on the last line of the citation, e.g., Avail: NTIS. The following are themost commonly indicated sources (full addresses of these organizations are listed at the

end of this introduction)

Avail: NTIS. Sold by the National Technical Information Service at the price shown in

the citation. If no price is shown in a current STAR citation, it may be ascertainedby referring to Government Reports Announcements or to NTIS. Beginning withdocuments announced in Issue 21, 1973, "stocked" reports, such as printed NASAreports are priced on a step schedule ranging irregularly from $3.00 for a 1-to-25page report to $11.00 for 576 to 600 pages, plus $2.00 for each additional100-page increment. Demand print reports (those for which a facsimile reproductionwill be made to fill orders) are priced at $4.00 for the first 20 pages plus 25 centsfor each five pages or portions thereof. These pR:ces are not applied retroactively;i.e.. reports previously announced at a cert- ice continue to be sold at thatprice.

Study of the effect of weightlessness on the functioning of thevestibular apparatus of the inner ear. It is shown that the absence ofgravity, especially in combination with other accelerations, can leadto a number of vegetative and psychic disturbances in astronauts,since the organ of balance of the inner ear requires the presence ofgravity as a stimulus to its proper functioning. In particular, theso-called 'space' sickness can occur. A.B.K.

The major systems of the Princeton Reference Design FusionReactor are reviewed from the point of view of identifying thehazards associated with normal and abnormal operation.Engineered safeguards and operational procedures are identifiedfor eliminating the hazards or minimizing their consequences.The most serious credible accident is identified as the designbasis accident and the design requirements specified for assuringthat the consequences of that accident will not exceed theregulatory limits for accident conditions. Data are provided toshow the maximum allowable levels of radiation and radioactivematerials for normal reactor operation. It is concluded that thefusion power plant can be operated without any significant hazardsto the public or plant personnel during normal operation. Formost modes of abnormal operation, hazards to the public arenot significant if the recommended safety procedures areinstituted. Author
