Peak expiratory flow rate (PEFR) was measured in 300 healthy adult male and female staff and students of the University of Benin, Benin City, and the College of Education, Ekiadolor, near Benin. The variations of Peak Expiratory Flow Rate with respect to height (ht), weight (wt) and chest circumference (cc) were determined in these subjects. PEFR values fell within the middle to the lower limit...

A simple, rapid and inexpensive monoparameter flow-through sensor has been developed for the determination of saccharin in low calorie and dietary products. The method is based on the transient adsorption of the sweetener on Sephadex G-25 solid phase packed to a height of 20 mm in the flow cell. The optimal transient retention of the synthetic sweetener, in terms of sensitivity and sampling fre...

OBJECTIVE To determine the optimal crank length and crank-axle height for maximum power production during standing arm cranking ("grinding"). METHODS Nine elite professional America's Cup grinders (age = 36 +/- 2 yr, body mass = 104 +/- 1 kg, body fat = 13% +/- 2%) performed eight maximal 6-s sprints on an adjustable standing arm-crank ergometer fitted with an SRM power crank. The protocol in...
