Stromal cells from subcutaneous adipose tissue (adipose derived stromal cells - ASCs) are perspective for cell therapy of ischemic states because of ability to stimulate growth of vessels. For the elucidation of mechanisms of angiogenic action of ASCs we used the model of co-cultivation of ASCs with cells isolated fro…
This thesis describes the development of a radiation detector which incorporates graphene into the device architecture through the use of FEM simulations and experiments with X-ray radiation. The device relies on sensing the changes in the local electric field arising from radiation interactions in a macroscopic absor…
Bio-oil is a dark-brown, mobile liquid derived from the thermo-chemical processing of biomass. Bio-oils generally contain water and lignin. Lignin is a highly-available, well-studied carbohydrate derivative known for its antioxidant properties. For asphalt pavements, oxidation can cause deterioration via long-term agi…
The objective of this work is to prove the hypothesis that there can be found at least one architecture of hydraulic hybrid that, when combined with a sophisticated control strategy, can yield better fuel economy than its electric hybrid counterpart. Investigation into various possible layouts of a power-split based h…

El hormigón armado, que surgió de forma industrial a principios del siglo XX, todavía hoy es el material más utilizado en las grandes obras de infraestructura y en la arquitectura contemporánea de edificios, por su capacidad de adaptarse bien tanto a las características geométricas del producto, como a la necesidad de…
In 2006, soil samples were collected at 960 sites (1 site per 280 square kilometers) throughout the state of Colorado. These samples were collected from a depth of 0-15 centimeters and, following a near-total multi-acid digestion, were analyzed for a suite of more than 40 major and trace elements. The resulting data s…
Point-to-plane and plane-to-plane electrostatic charge injection atomization for insulating liquids.
New insulation materials can be tailored by compounding nanofillers and polymer materials. The advantageous changes in properties of polymer nanocomposites can be explained by the large interface area of the nanofillers. Theoretical models developed in the field of nanodielectrics concentrate on the analysis of the in…
Adhesive bonded applications are used widely in industry because of significant advantages such as uniform stress distribution, and the ability to join different materials.However most epoxy structural adhesives are brittle at room temperature and it is required to improve their toughness.The objective of this work wa…
Phase change materials, typically composed out of Ge, Sb and Te alloys, are materials that can switch very fast between two stable states, the amorphous and the crystalline phase. The optical contrast of the two stable phases led to the application in optical data storage such as compact disks (CD), digital versatile…
Preface Post-Impact Fatigue Behaviour of Composite Laminates: Current and Novel Technologies for Enhanced Damage Tolerance Collagen Composites for Tissue Engineering Composite Multi-layer Coatings for Improved Barrier Properties of Packaging Board Simulation of Ultimate Strength of Fibre-Reinforced Composites by Means…
Accelerator-driven systems have been proposed for incineration of transuranic elements from spent nuclear fuel. For safe operation of such facilities, a robust method for reactivity monitoring is required. Experience has shown that the performance of reactivity measurement methods in terms of accuracy and applicabilit…

With large amounts of time and money invested in the advancement of aerospace structures, the performance and reliability are crucial factors in the development of new components to extend the lifetime of these spacecrafts. Wires composed of long, highly aligned, and defect-free carbon nanotubes (CNTs) could have a gr…
In minerals processing, froth flotation is used to separate valuable metal minerals from ore. The efficiency of a froth to recover these valuable minerals is closely related to the bubble size distribution through the depth of the froth. Measurement of the bubble size entering the froth and at the froth surface has be…
Fish oil is an excellent source of long chain polyunsaturated fatty acids (LC-PUFA), which can reduce the risk of cardiovascular disease in addition to other health benefits. However, the average intake of LC-PUFA in the Western diet is much lower than the recommended levels. Fish oil is prone to oxidative deteriorati…
Novel plastics that are biodegradable and made from renewable natural resources are currently being researched as alternatives to traditional petroleum-based plastics. One such plastic, thermoplastic starch (TPS) is produced from starch processed at high temperatures in the presence of plasticizers, such as water and…
Fullerenes are all-carbon molecules with polyhedral structures where each atom is bonded with three other atoms and the faces of the polyhedron are pentagons and hexagons. Fullerene graphs model the fullerene structures and are cubic planar graphs having twelve pentagonal faces and the remaining faces are hexagonal. T…
