In this paper, a direct method-based prediction of load-bearing capacity of nonperiodic WC-Co composites is presented. The main goal is to generalize the methodology of limit analysis on periodic heterogeneous media to materials with random microstructures. For such materials, the admissible macroscopic loading domain…
Aggregation and membrane penetration of porphyrinic photosensitizers play crucial roles for their efficacy in photodynamic therapy. The current study was aimed at comparing the aggregation behavior of selected photosensitizers and correlating it with membrane affinity. Self-assembling properties of 15 amphiphilic free…
Composite materials, such as glass fibre reinforced polymers (GFRPs), possess the advantages of high strength and stiffness, low density, as well as manufacturing flexibility; therefore, their potential in replacing conventional materials (such as concrete, aluminium and steel) in building construction has become attr…
This paper is devoted to the new magnesium alloys used in medicine as a soluble implants. Feature of these alloys is a low technological ductility in cold forming. The problem of determination of the cold thin wire (diameter less than 0.1mm) drawing process parameters for hardly deformable biocompatible magnesium allo…
A novel triblock macromolecular architecture based on cyclodextrin (CD) complexation is presented. A CD-functionalized biocompatible poly(N-(2-hydroxypropyl)methacrylamide) (PHPMA) building block (3800 ≤ M n ≤ 10 600 g mol-1; 1.29 ≤ Crossed D sign M ≤ 1.46) and doubly guest-containing poly(N,N-dimethylacrylamide) (PDM…
Coiled steel strip is the final product from flat hot rolling processes. With increasing demand for higher quality of hot rolled strips, especially the evolution of strip flatness during and after coiling becomes a crucial aspect. The main impacts on the flatness properties of hot rolled strips result from residual st…
Due to strong thermo-mechanical coupling in shape memory alloys (SMAs), heat generation/absorption during forward/reverse phase transformation can cause temperature variations in the material; influencing its mechanical behaviour. It is usually assumed that this coupling is only affected by the loading rate. But, rece…
The nucleosome core particle is a highly conserved structure which can play diverse roles depending on the organism, cell, or part of chromatin in which it resides. The Protein Data Bank currently contains approximately 70 nucleosome core particle structures, over half of which were determined in the last three years.…
The mechanical properties of individual multiwall boron nitride nanotubes (MWBNNTs) synthesized by a growth-vapor-trapping chemical vapor deposition method are investigated by a three-point bending technique via atomic force microscopy. Multiple locations on suspended tubes are probed in order to determine the boundar…
Esta tesis se ha centrado en el estudio del papel de las moleculas de adhesion integrinas en la morfogenesis de epitelios. En concreto, ha analizado la funcion de las integrinas en tres procesos: supervivencia celular, diferenciacion y proliferacion. Para ello se ha utilizado la mosca Drosophila melanogaster como sist…
We study gradient flow formulations of thin-film bilayer flows with triple-junctions between liquid/liquid/air. First we highlight the gradient structure in the Stokes free-boundary flow and identify its solutions with the well-known PDE with boundary conditions. Next we propose a similar gradient formulation for the…
The coherent excitations of DNA hydration water at 100 K have been investigated by neutron scattering spectroscopy to extract the excess signal of D₂O-hydrated DNA with respect to dry DNA samples. A structural characterization of the sample, through the analysis of the static structure factor, has suggested that DNA h…
Este trabajo se fundamenta en el estudio de la fabricacion de estructuras sub-micrometricas mediante la tecnica Litografia por Interferencia Laser (LIL). En este trabajo se utilizan dos tecnicas de fabricacion. En la primera, el patron de interferencia se transfiere a la resina y posteriormente mediante procesos adici…
Additives which alter surface tension can greatly enhance the performance of waterborne coatings. Additive manufacturers promote three major classes of surface tension modifiers, surfactants, silicones, and acetylenic diols. Some of these are based on “green” technology and thus friendly to the environment in addition…
Functional coatings are the next generation technology being engineered to reduce costs in maritime transport containers. Cargo containers ship different products that require cleaning between shipments, which takes time and energy. A lipase enhanced tank liner coating was engineered to reduce the cleaning time betwee…
In this work, a homogenization strategy for a micromorphic–type inelastic material is presented. In the spirit of FE2, a representative volume element is attached to each macroscopic quadrature point. Due to the inherent length scale of the micromorphic continuum, size effects for inelastic behavior are obtained on RVE…

La vitamine B6 est d'une importance primordiale dans tous les organismes et agit, sous la forme de phosphate de pyridoxal (PPL), comme cofacteur pour de nombreuses enzymes métaboliques. La principale voie menant à la biosynthèse de la vitamine B6 fut récemment étudiée et implique deux enzymes, PDX1 et PDX2 pour la pro…
As petroleum resources are finite, it is imperative to use them wisely in energy conversion applications and, at the same time, develop alternative energy sources. Biomass is one of the renewable energy sources that can be used to partially replace fossil fuels. Biomass-based fuels can be produced domestically and can…
Electrophoretic deposition has emerged as a versatile and precisely tunable approach for the rapid deposition of conformal thin films of colloidal nanocrystals. The electrophoretic deposition of phosphor particles has assumed special significance in recent years as a commercially viable means toward the fabrication of…
