In this paper, we present the dynamic layer displacement–layer displacement and the dynamic densitydensity correlation functions—both for smectic-A systems in the thermodynamic limit, and for real smectic-A films that have finite size, nonzero surface tension acting at the two free surfaces, and nonzero layer sliding viscosity. We also present the results of our soft-x-ray photon correlation sp...

conclusions children engaged with regular football practice presented enhanced physical fitness and autonomic function, by increasing vagal tone at rest. results the anthropometric and body composition characteristics were similar in both groups (p > 0.05). the groups were also similar in time spent daily on moderate-to-vigorous physical activities (fg vs. cg: 114 ± 64 vs. 87 ± 55 minutes; p > ...

This paper examines which rehearsal method (physical practice vs. mental practice) can better strengthen spatial memory. Participants were asked to learn four routes that navigated from starting points to destinations in four different maps. Then they were asked to rehearse the routes by using one of the following methods: 1) mental practice by simulating the routes in their mind; 2) physical p...

objectives the aim of this study was to identify the relation between physical activity level and the structures of trans-theoretical model (ttm). materials and methods this cross-sectional study was conducted on 423 female students of tonekabon in iran. participants completed the demographic questionnaires, the ttm’s structural questionnaires as well as the international physical activity ques...
