Correlations of isokinetic and psychophysical back lift and static back extensor endurance tests in men
1994
Isokinetic lift, psychophysical lift, and static back endurance tests are among the most widely used measurements of muscle function for determining risk for, and recovery from, back problems. After determining test repeatability we examined the degree of association between these test measures in 100 men selected to represent a variety of occupations and lifestyles. Isokinetic lifting had low correlations with test results for psychophysical lifting (r = 0.28) and static back endurance (r = 0.24). Static back endurance and psychophysical lift test results were not at all correlated (r = 0.03). RELEVANCE--:Muscle function measurements for back problems are sometimes arbitrarily selected due…
Bedeutung von Assoziationsphänomenen quartärer Oniumverbindungen in der organischen Phase für den Ablauf phasentransferktalysierter Reaktionen
1980
Quartare Oniumsalze sind, wie dampfdruckosmometrische Messungen zeigen, in Benzol und Chloroform assoziiert [in Benzol starker (Faktor 4–15) als in Chloroform (Faktor 1.2 – 2.4)]. Im Homogen- und Zweiphasensystem laufen die Modellreaktionen (1) und (2) mit steigendem Assoziationsgrad schneller ab — langsamer im Zweiphasensystem wegen des Wassergehaltes der organischen Phase (Verminderung des Assoziationsgrades). Assoziationsphanomene sind offensichtlich fur die “Katalyse” im Zweiphasensystem wesentlich.
