Notes: Abstract To quantify fluid distribution at a moderate altitude (2,315 m) 29 male subjects were studied with respect to tissue thickness changes [front (forehead), sternum, tibia], changes of total body water, changes of plasma volume, total protein concentrations (TPC), colloid osmotic pressure (COP), and electrolytes. Tissue thickness at the forehead showed a significant increase from 4.14 mm to 4.41 mm 48 h after ascent to the Rudolfshuette (2,315 m) (P 〈 0.05). At 96 h after ascent the tissue thickness at the tibia was decreased to 1.33 mm compared to the control value of 1.59 mm (P 〈 0.01). Body mass increased from 75.5 kg (control) to 76.2 kg on the last day (P 〈 0.05) and body water from 44.21 to 45.01 during the week (P 〈 0.01). The accumulation fluid in the upper part of the body was paralleled by a decrease in TPC and COP. At 48 h after the ascent COP dropped from 29.5 mmHg to 27.5 mmHg (P 〈 0.01). After 96 h at moderate altitude COP was still significantly decreased compared to the control level. At 1.5 h after the return from the Rudolfshuette in Saalfelden (744m) COP was back to the control values. The TPC also showed an initial drop from 7.75 g · dl−1 to 7.48 g · dl−1 after 48 h at altitude and remained below the control value during the whole week (P 〈 0.01). It seems from our study that even with exposure to moderate altitude measurable fluid shifts to the upper part of the body occurred which were detected by our ultrasound method.

Description / Table of Contents: Novel Fast Ion Conductors of the Type MI3MIIICl6 (MI = Li, Na, Ag; MIII = In, Y)The ternary chlorides Li3InCl6, Na3InCl6, Ag3InCl6, and Li3YCl6 have been studied by difference scanning calorimetry, high-temperature X-ray, infrared, and high-temperature Raman methods. Impedance spectroscopic measurements exhibit fast ionic conductivity increasing in the sequence Na3InCl6 〈 Li3YCl6 〈 Ag3InCl6 〈 Li3InCl6. In the range of 300°C, Li3InCl6 is the best lithium ion conductor known so far (σ = 0,2 Ω-1 cm-1 at 300°C). With the exception of Na3InCl6, the chlorides exhibit complicated order-disorder phase transitions.

Notes: Li3InCl6 Na3InCl6, Ag3InCl6 und Li3YCl6 wurden mittels thermoanalytischer (DSC), röntgenographischer, IR- und Raman-spektroskopischer Methoden (einschließlich Röntgen- und Ramanheizaufnahmen) charakterisiert. Impedanzspektroskopische Messungen ergaben eine sehr hohe Ionenleitfähigkeit (Na3InCl6 〈 Li3YCl6 〈 Ag3InCl6 〈 Li3InCl6). Li3InCl6 ist im Bereich von 300°C der bisher beste Lithiumionenleiter (σ = 0,2 Ω-1 cm-1). Mit Ausnahme von Na3InCl6 sind die hier untersuchten ternären Chloride polymorph mit komplizierten Ordnungs-Unordnungs-Phasenumwandlungen.
