The nonlinearity index is a measure of the nonlinearity of dynamical systems based on computing the initial-condition sensitivity of the statetransition matrix. The Cayley form is a representation for dynamical systems that relates their motion to N -dimensional rotations. The generalized coordinates of the system are used to define an N -dimensional orientation, and a set of quasi velocities i...

This essay looks at the historical significance of three APS classic papers that are freely available online: Hammel HT, Hardy JD, and Fusco MM. Thermoregulatory responses to hypothalamic cooling in unanesthetized dogs. Am J Physiol 198: 481-486, 1960 (http://ajplegacy.physiology.org/cgi/reprint/198/3/481).

In this study, PP films were modified with an organic pro-degradant in different concentrations (1, 2 and 3 wt.%), exposed in the first step of degradation to natural ageing for 100 days followed by biodegradation in simulated soil in the respirometric test for 100 days. At the end of the combined degradation process the PP samples were characterized according to their morphological and physica...

nanocomposites based on polyamide 6/polypropylene  )pa6/pp 67/33) blend containing 2.5 to 10 phr of nano-caco3  and 5 phr of maleated polypropylene )pp-g-mah) as compatibilizer were prepared by melt compounding followed by injection molding. the mechanical properties, water absorption, as well as shrinkage behavior were characterized and the morphology was studied using scanning electron micros...
