We report that the properties of the isotropic to nematic liquid crystalline phase transition of F-actin depend critically on the average filament length. For average filament lengths longer than 2 microm, we confirm previous findings that the phase transition is continuous in both alignment and concentration. For average filament lengths shorter than 2 microm, we show for the first time a firs...

Inert, spherical heterogeneities can pin three-dimensional scroll waves in the excitable Belousov-Zhabotinsky reaction. Three pinning sites cause initially circular rotation backbones to approach equilateral triangles. The resulting stationary shapes show convex deviations that increase with decreasing anchor radii. This dependence is interpreted as a transition between filament termination at ...

Physical properties of cotton yarns are affected by the characteristics of cotton fibers such as fineness, length, maturity and strength. This relationship has been worked out by means of multivariable regression and stepwise method for an open-end spun (NeC 20) cotton yarn. Moreover, with the help of linear programming, it was made possible to determine the percentage of different cottons in t...

Interface optimisation for continuous hemp reinforcements in epoxy resin is a current challenge the development of biocomposites. A chemical treatment based on hydrogen peroxide and physical one using non-thermal plasma have been tested to optimise interface adhesion, by varying several parameters. FTIR analysis FE-SEM observations shown effects treatments morphological aspects treated yarns. T...

The filament winding process is a competitive performing technology for nuclear fuel cladding tubes due to its high automation. study of the yarn path on mandrel surface vital design and produce tube with desired mechanical properties, reducing manufacturing time costs. geodesic semi-geodesic trajectories are used create 3D in this paper. A optimization method based principle minimum potential ...

While tailoring a garment or a technical textile, relaxation processes of a knitted fabric after production have to be taken into account. Such dimensional changes can occur during a long time of dry relaxation, during wet relaxation, or during washing relaxation, the latter having the strongest infl uence on a fabric. Besides fabric construction and yarn material, the dimensions of a knitted f...
