steady-state values were represented by the half-times (t£) 0.17 and 0.23 minutes respectively. The turnover rate in venous blood oxygen content proceeded at a considerably slower rate, t i=0.75 minutes. The data presented here will be useful in constructing models to predict changes in body oxygen

Relationship between turnover rate and blood concentration of lactate in

mansoni; relationship between membrane turnover rates and susceptibility to immune damage, (part of a coordinated pro-gramme on preparation of irradiated vaccines against some human diseases)

The authors conducted a meta-analysis of the relationship between turnover rates and organizational performance to (a) determine the magnitude of the relationship; (b) test organization-, context-, and methods-related moderators of the relationship; and (c) suggest future directions

isolation of hydrocortisone from the urine of a patient with Cushing's syndrome, and thus pro-vided evidence that hydrocortisone was produced by the human adrenal cortex. Subsequently, hy-drocortisone was found to be one of the principal corticoids in human adrenal gland perfusates (2) and in human peripheral blood (3). These ob-servations strongly suggest that hydrocortisone may be the principal corticosteroid secreted by the adrenal cortex of man. Recent studies (4, 5) utilizing hydrocortisone-4-Cli have elucidated much new information regarding the metabolism and physiological disposition in man of this natu-rally occurring adrenal steroid. The availability of labeled hydrocortisone has

SUMMARY The half-lives of a number of serum enzymes were derived in a patient with acute muscle necrosis. A unit of plasma was withdrawn from the patient during the height of his illness and was infused back into his circulation when he had recovered. The disappearance rates of six commonly

higher rates, contrary to conventional wisdom, neither larger schools, nor public schools in large school districts, nor urban public schools have especially high rates of teacher turnover. In

This study investigated the effect of external carbon source and bed turnover rate on biological denitrifi-cation in the pilot-scale IPNR (Ilshin Phosphorus and Nitrate Removal) process. IPNR process is an up-flow reactor filled with Si-media which removes phosphorus physically and nitrate nitrogen
