Scrutiny of the Failure of Lipid Membranes As A Function of Headgroups, Chain Length, and Lamellarity Measured by Scanning Force Microscopy

2004

AbstractA fast, quantitative, and unambiguous screening of material properties of biomembranes using scanning force microscopy in pulsed force mode on lipid membranes is presented. The spatially resolved study of breakthrough force, breakthrough distance, adhesion, stiffness, and topography of lipid membranes as determined simultaneously by digitalized pulsed force mode provides new insight into the structure-function relationship of model membranes, which are systematically analyzed by varying chain length, lipid headgroup, and lamellarity. For this purpose, a novel unbiased analysis method is presented. A strong correlation between adhesion and breakthrough events is found on lipid bilaye…

Comparison of two techniques (in vivo and ex-vivo) for evaluating the elastic properties of the ascending aorta: Prospective cohort study.

2021

Introduction Aneurysms of the ascending aorta (AA) correspond to a dilatation of the ascending aorta that progressively evolves over several years. The main complication of aneurysms of the ascending aorta is type A aortic dissection, which is associated with very high rates of morbidity and mortality. Prophylactic ascending aorta replacement guidelines are currently based on maximal AA diameter. However, this criterion is imperfect. Stretching tests on the aorta carried out ex-vivo make it possible to determine the elastic properties of healthy and aneurysmal aortic fragments (tension test, resistance before rupture). For several years now, cardiac magnetic resonance imaging (MRI) has pro…

Magnetic properties of some rare‐earth magnesium compounds RMg2

1981

The magnetic properties of the compounds PrMg2, NdMg2, DyMg2, and ErMg2 were studied by means of neutron diffraction at various temperatures. All these compounds give rise to ferromagnetic ordering. The absolute values of the magnetic moments in the magnetically ordered state are lower than the free‐ion values. Inelastic neutron scattering at several temperatures was studied in PrMg2 and NdMg2. Analysis of the scattering data in conjunction with the results of specific‐heat and magnetization measurements shows that PrMg2 is an induced‐moment system (G3 ground state), where quadrupolar effects carry a large weight in determining the magnetic properties. The values found for the crystal‐field…

Boundary element method for magneto-electro-elastic laminates

2006

A boundary integral formulation and its numerical implementation are presented for the analysis of magneto-electro-elastic media. The problem is formulated by using a suitable set of generalized variables. The governing boundary integral equation is obtained by generalizing the reciprocity theorem to the magneto-electro-elasticity. The fundamental solutions are calculated through a modified Lekhnitskii’s approach, reformulated in terms of generalized magneto-electroelastic displacements. To assess the reliability and effectiveness of the formulation, some numerical analyses have been carried out and the convergence of the method has been studied. The multidomain approach has been developed …

Large deflection analysis of magneto-electro-elastic laminates

2013

Magneto-electro-elastic (MEE) composites containing piezoelectric and piezo-magnetic phases have recently emerged for many application smart structures technology. In this framework, the development of tools to analyze the MEE laminates is essential for their efficient design. In the present work, a model for the large deflection analysis of MEE laminated plates is proposed. The first order shear deformation theory and the von Karman stress function approach are employed to model the mechanical behavior whereas quasi-static behavior is assumed for the electro-magnetic quantities. First, the magneto-electric problem is solved in terms of the plate mechanical primary variables. In turn, this …

Dynamic analysis of damaged magnetoelectroelastic laminated structures

2010

In the present paper a boundary element analysis of the dynamic response of damaged magnetoelectroelastic laminate structures is presented. The problem is formulated employing generalized displacements. The mass matrix is computed by the Dual Reciprocity Method. Due to the non-homogeneous nature of the laminate the multidomain boundary element technique is employed which also straightforwardly allows the modeling of interface cracks and delaminations. The multidomain boundary element technique is implemented with imperfect interlaminar interfaces and unilateral interface conditions to prevent the physical inconsistence of the overlapping between interface nodes belonging to two different pl…
