While Chapter 6 deals with short-term adjustments, there are also long term adjustments to traveling in space, including loss of bone and muscle mass, the need for different medicine regimens, adjusting to the environment and its cycles of sounds, vibrations, and lights. Learning to sleep in microgravity. Adjusting to the effects of cosmic rays, which cause flashes of light.

B. P. Konstantinov and G. E. Kocharov (1965, 1967) addressed the complex problem of astrophysical phenomena and radiocarbon. Currently available data show that the determination of cosmogenic 14C in accurately dated samples of terrestrial and atmospheric origin is one of the most reliable and promising methods for studying cosmic-ray variations in the past. 14C dating samples of terrestrial origin has helped solve the problem of long-term (100 yr or more) 14C variations and, accordingly, of cosmic-ray variations in the past. Short-term (ca. 11 yr or less) variations are still under investigation (Alexeyev et al. 1971; Damon, Long and Wallick 1973).

The magnetic rigidity spectrum of primary cosmic rays with Z ≥ 6, in the rigidity interval 2·5 to 16·0 GV, has been determined by means of a Cerenkov counter carried in the satellite Ariel. The integral spectrum shows a well-defined change in slope near 8·5 GV, indicating that this is probably the upper limit to the solar modulation process at this time (May and June 1962). In the rigidity interval covered by these measurements the integral spectrum is adequately represented by a power law with an exponent ca . 1.2 below 8.5 GV and ca . 1.5 above this rigidity. Under the plausible assumption that the integral galactic spectrum of these particles is represented by a power law with exponent 1·5, it follows that the solar modulation process in the 2·5 to 8·5 GV region is of the form J E = J ∞ [p/p o ] 0·3 , where J E is the intensity at the Earth of particles with rigidity greater than p , where p is in GV, J ∞ is the corresponding intensity outside the solar system, and p 0 ~ 8·5.

AbstractRapid serial visual presentation (RSVP) of words or pictured scenes provides evidence for a large-capacity conceptual short-term memory (CSTM) that momentarily provides rich associated material from long-term memory, permitting rapid chunking (Potter 1993; 2009; 2012). In perception of scenes as well as language comprehension, we make use of knowledge that briefly exceeds the supposed limits of working memory.

Previous short term toxicological studies of one to two weeks duration have demonstrated that MDL 19,660 (5-(4-chlorophenyl)-2,4-dihydro-2,4-dimethyl-3Hl, 2,4-triazole-3-thione), an antidepressant drug, causes a dose-related thrombocytopenia in dogs. Platelet counts started to decline after two days of dosing with 30 mg/kg/day and continued to decrease to their lowest levels by 5-7 days. The loss in platelets was primarily of the small discoid subpopulation. In vitro studies have also indicated that MDL 19,660: does not spontaneously aggregate canine platelets and has moderate antiaggregating properties by inhibiting ADP-induced aggregation. The objectives of the present investigation of MDL 19,660 were to evaluate ultrastructurally long term effects on platelet internal architecture and changes in subpopulations of platelets and megakaryocytes.Nine male and nine female beagle dogs were divided equally into three groups and were administered orally 0, 15, or 30 mg/kg/day of MDL 19,660 for three months. Compared to a control platelet range of 353,000- 452,000/μl, a doserelated thrombocytopenia reached a maximum severity of an average of 135,000/μl for the 15 mg/kg/day dogs after two weeks and 81,000/μl for the 30 mg/kg/day dogs after one week.
