摘要：Solutions of 1000 and 2000 ppm (mg. per liter) of Na2SO4, NaHCO3, CaSO4, MgSO4, NaCl, CaCl2, and Na2CO3 were rated on an acceptability scale in 3 separate studies. Results showed that the minerals ranked acceptability approximately as listed. Implications of the findings were discussed mainly in regard to detection thresholds for the 8 minerals and consumer-acceptance of naturally mineralized ground waters used for domestic supplies.

摘要：Using a compression chamber, Kiessling and Maag (1962) showed a decline in manual dexterity at a pressure simulating 100 ft. of water. Impairment was slight (7.9%) and was assumed to be of little practical importance. The present study examines this conclusion by testing divers in the water. The manual dexterity and tactile sensitivity of 12 free divers were tested above the surface, and at 10 and 100 ft. below the surface. The dexterity test took 28% longer at 10 ft. and 49% longer at 100 ft....

摘要：Twelve United States Army enlisted men were tested on 3 manual tasks, knot-tying (KT), block-stringing (BS), and block-packing (BP), under 4 conditions: Control-Mean Weighted Skin Temperature (MWST) 90.0[degree] F., Hand Skin Temperature (HST) 93.0[degree] F; Cold Body-MWST 69.0[degree] F., HST 90.4[degree] F; Cold Hand-MWST 85.8[degree] F., HST 45.7[degree] F and Cold Hand-Body-MWST 68.5[degree] F., HST 45.8[degree] F. The 3 cooling conditions had a differential effect across the 3 tasks. Col...
