Sedentary behaviours and its association with bone mass in adolescents: the HELENA cross-sectional study
(BIOMED CENTRAL LTDLONDON, 2012)
Background: We aimed to examine whether time spent on different sedentary behaviours is associated with bone mineral content (BMC) in adolescents, after controlling for relevant confounders such as lean mass and objectively ...
Examples of Physical Systems Described by the Duffing Equation
(2011-03-03)
In this chapter several examples of physical systems whose dynamic behaviour can be approximated by several forms of the Duffing equation are given. The physical systems are chosen to illustrate the physical phenomena that ...
Comparative degradation of ZnO- and SnO(2)-based polycrystalline non-ohmic devices by current pulse stress
(IOP PUBLISHING LTD, 2008)
The degradation behaviour of SnO(2)-based varistors (SCNCr) due to current pulses (8/20 mu s) is reported here for the first time in comparison with the ZnO-based commercial varistors (ZnO). Puncturing and/or cracking ...
