In recent years, glass-fiber reinforced composite materials are more and more used in structural applications. Their mechanical properties: low density, high strength and high chemical corrosionresistance offer an interesting alternative solution to metallic or concrete material. The pultrusion is a composite material processing technique that is penetrating the civil engineering market since t...

We consider the 3D smectic energy $$\begin{aligned} {\mathcal {E}}_{\epsilon }\left( u\right) =\frac{1}{2}\int _{\Omega }\frac{1}{\varepsilon } \left( \partial _{z}u-\frac{(\partial _{x}u)^{2}+(\partial _{y}u)^{2}}{2}\right) ^{2} +\varepsilon _{x}^{2}u+\partial _{y}^{2}u\right) ^{2}dx\,dy\,dz. \end{aligned}$$ The model contains as a special case well-known 2D Aviles-Giga model. prove sharp lowe...

Furfural (F) cannot be easily polymerized like furfuryl alcohol, but it is an aldehyde that can react with urea (U) to make a polymeric network. The possibility of preparing F/U polymer along acidic catalyzer (maleic anhydride; M) was evaluated as means improve some selected properties birch (Betula pendula) wood. F+U/M resin introduced into the wood double treatment technology. first step invo...

Springback and longitudinal bow are two major shape defects in gradual forming processes like chain-die roll forming. In this study, the springback of AHSS hat U profiles investigated through experiment finite element simulation. The disparity along direction signifies complex deformation during Based on simulation forming, process realized by sequential die blocks causes bending reverse-bendin...

Globotriaosylceramide (Gb3) is a glycosphingolipid present in the plasma membrane that is the natural receptor of the bacterial Shiga toxin. The unsaturation level of Gb3 acyl chains has a drastic impact on lipid bilayer properties and phase behaviour, and on many Gb3-related cellular processes. For example: the Shiga toxin B subunit forms tubular invaginations in the presence of Gb3 with an un...

the spline finite strip method (s.f.s.m.) for buckling analysis of plates and plate assemblies subjected to longitudinal compression and bending, transverse compression as well as shear is described. the method allows for the boundary conditions. local buckling coefficients of plates with different boundary conditions under compression, bending and shear are calculated. convergence studies with...
