OBJECTIVE To compare lung volumes in a large cross sectional sample of Greek swimmers, land based athletes, and sedentary controls by means of allometric scaling. METHODS Four hundred and fifty nine asymptomatic Greek children and young adults (age 10-21 years), including 159 swimmers, 130 land based athletes, and 170 sedentary controls, performed forced(More)
The efficacy of piperacillin/tazobactam at 100/12.5 mg/kg every 8 h (35 patients) was compared to cefotaxime plus metronidazole at 50/7.5 mg/kg every 8 h (35 patients) in 70 children with intra-abdominal infections requiring surgery. Diagnoses were gangrenous or perforated appendicitis (n =56), peritonitis (n =12), and abscess (n =2). Clinical cure was(More)
OBJECTIVE To examine whether time of day significantly affects salivary cortisol and IgA levels before and after submaximal swimming. METHODS Fourteen male competitive swimmers (mean (SD) age 18 (3.2) years) volunteered to participate in the study. In a fully randomised, cross over design, each subject performed 5 x 400 m front crawl at 85 (1.2)% of their(More)
This paper presents an adaptive hybrid fuzzy rule-based system (FRBS) approach for the modeling and short-term forecasting of traffic flow in urban arterial networks. Such an approach possesses the advantage of suitably addressing data imprecision and uncertainty, and it enables the incorporation of expert's knowledge on local traffic conditions within the(More)
In the current social, physical, economical and environmental circumstances of scarcity, the design and management of vital lifelines like transportation systems, especially within the metropolitan context, are subject to the implementation of multiple objectives in a unified framework. Thus, one of the most important issues is the identification of optimal(More)
