Some diverse examples of exploiting the beneficial effects of geometric stiffness nonlinearity
(2019-06-15)
The effects of nonlinearity, particularly stiffness nonlinearity, has been of concern to structural engineers for many years. The main reason for this is because this type of nonlinearity can cause unpredictable dynamics, ...
A note on non-linear phenomena in a non-ideal oscillator, with a snap-through truss absorber, including parameter uncertainties
(2013-03-01)
This work considers the vibrating system that consists of a snap-through truss absorber coupled to an oscillator under excitation of an electric motor with an eccentricity and limited power, characterizing a non-ideal ...

Blood flow distribution in embryonic common snapping turtles Chelydra serpentina (Reptilia; Chelonia) during acute hypoxia and alpha-adrenergic regulation
(Elsevier B.V., 2019-12-01)
Embryonic turtles have four distinct vascular beds that separately perfuse the developing embryo's body and the extra-embryonic yolk sac, amnion and chorioallantoic membrane (CAM). The mechanisms enabling differential ...
The low molecular weight S-nitrosothiol, S-nitroso-N-acetylpenicillamine, promotes cell cycle progression in rabbit aortic endothelial cells
(Elsevier B.V., 2008-06-01)
S-Nitrosylation reactions are considered to be a major mechanism by which NO-related bioactivities are regulated in vivo. in the present study, we show the effects of the low molecular weight S-nitrosothiol, S-nitroso-N- ...
