Guiding cell migration with microscale stiffness patterns and undulated surfaces
(Elsevier, 2016-07)
By placing stiff structures under soft materials, prior studies have demonstrated that cells sense and prefer to position themselves over the stiff structures. However, an understanding of how cells migrate on such surfaces ...
Influence of the number of load cycles to obtain the stiffness properties of angico preto (<i>Anadenanthera macrocarpa</i>) wood specie
(2015)
The tests used to obtain the stiffness properties of wood are made with two loading cycles, as defined by the Brazilian standard ABNT NBR 7190 (Design of Timber Structures). However, the possibility of reducing the number ...
On the undamped free vibration of a mass interacting with a Hertzian contact stiffness
(2011-12-01)
Three methods are used to determine the natural frequency of undamped free vibration of a mass interacting with a Hertzian contact stiffness. The exact value is determined using the first integral of motion. The harmonic ...
Passive vibration isolation using axially loaded curved beams
(2011-12-01)
A nonlinear spring element of a vibration isolator should ideally possess high static and low dynamic stiffness. A buckled beam may be a good candidate to fulfil this requirement provided its internal resonance frequencies ...

Stiffness of lipid monolayers with phase coexistence
(American Chemical Society, 2013-08)
The surface dilational modulus (or compressibility modulus) has been previously studied for monolayers composed of pure materials, where a jump in this modulus was related with the onset of percolation as a result of the ...
Alterations in myocardial collagen content affect rat papillary muscle function
(Amer Physiological Soc, 2000-10-01)
We investigated the influence of myocardial collagen volume fraction (CVF, %) and hydroxyproline concentration (mu g/mg) on rat papillary muscle function. Collagen excess was obtained in 10 rats with unilateral renal ...

Alterations in myocardial collagen content affect rat papillary muscle function
(2000-01-01)
We investigated the influence of myocardial collagen volume fraction (CVF, %) and hydroxyproline concentration (μg/mg) on rat papillary muscle function. Collagen excess was obtained in 10 rats with unilateral renal ischemia ...
On the detailed design of a quasi-zero stiffness device to assist in the realisation of a translational Lanchester damper
(2022-02-01)
A translational Lanchester damper is a device that adds damping to a structure at a point using a series combination of a viscous damper and a mass. The problem in the practical realisation of such a device is that a ...
