Chapter 1. A brief history of the use of ionizing radiation for cancer therapy is presented, as the motivation for modern clinical investigations on alpha therapy and the use and development of bifunctional chelators in targeted medicine. Recent studies on targeted therapy with alpha-emitters, such as 223Ra and 227Th,…
Hydrogen gas is considered as the key "green" technology for its endless production-consumption procedure, known better as the "water-cycle". In this cycle, hydrogen is directly produced from water electrolysis and while forms water again, when combusted with oxygen, releasing energy. However, as the most lightweight…
On the base of the algorithm steps in time the problem is formulated for inelastic deformation of laminated beams-wall of Tymoshenko type of regular structure. The behavior of materials layers describes by nonlinear-hereditary Rabotnov's creep theory. The calculations are carried out for unsteady creep of double-beat…
We report a first-principles study of electrical transport in a single molecular conductor consisting of a buthane-dithiol sandwiched between two Au (100) electrodes. We show that the current was increased by increasing of the external voltage biases. The projected density of states (PDOS) and transmission coefficient…
Temporary closure of plastic pipes by squeeze-off - state of the art State of the art and present use of squeeze-off methods for temporary closure of polymer pipelines for water and gas was investigated by an enquiry and a literature study. A limited, supplementary series of tests was also performed. The aim was to fi…
An entry from the Cambridge Structural Database, the world’s repository for small molecule crystal structures. The entry contains experimental data from a crystal diffraction study. The deposited dataset for this entry is freely available from the CCDC and typically includes 3D coordinates, cell parameters, space grou…
In the scope of the co-operation within the EDA on Insensitive Munitions and ageing, TNO has carried out an investigation on the effects of ageing on the vulnerability characteristics of energetic materials. For this study pristine and accelerated aged RDX-based polymer bonded explosives (PBX) have been subjected to l…

We report the results of our studies on optical and thermal properties of ternarymixture of three compounds viz., 4ÂÂ-n-octyl-4-cyanobiphenyl (8CB), Didodecyl dimethyl ammonium bromide (DDAB) and Glacial acetic acid (GAA). Higher concentrations of the givenmixture showa very interesting reentrant nematic phase, seque…
An investigation was made of the effect of mechanical strain on the electrical properties of composites based on nitrile butadiene rubber. It was shown that general conductivity of the composite is ensured by the formation of direct contact between particles of the conductive filler, which leads to the formation of a…
The paper presents the results of numerical investigation on a basis of previously published methodic of the process of destruction of thin-walled tubular specimen, partially submerged in liquid chlorine-containing environment at various levels of the axial tensile stresses. The comparison of the results of numerical…
The problem of defining the reliability and the residual life of thin-walled structures is solved in terms of the principle of safe damage (the growth of fatigue cracks) at zones of stress concentrators. Keywords: safe damage, reliability, residual life, fatigue cracks.
Spherical particles of a Sidistar R silica type with a BET surface area of only 20 m2/g can be used to improve the processing behaviour of Noxtite HT-ACM based compounds without loss of physical properties or chemical resistance to meet the requirements of automotive applications. This silica can be added on top of ex…
Der Kristallisationsprozess supramolekularer Blockcopolymere ist deutlich komplexer verglichen mit kovalent gebundenen Blockcopolymeren. Das Ziel dieser Arbeit war supramolekulare Blockcopolymere mit verschiedenen Molmassen herzustellen und deren Kristallisationsverhalten zu untersuchen. Die drei untersuchten Gruppen…
Electrical sensitivity of a boron nitride nanotube (BNNT) was examined toward C2H5OH molecules by using density functional theory (DFT) calculations . It was founding that the adsorption energy(Ead) of ethanol on the pristine nanotubes is about -51.5 kJ / mol, but when the nanotube has been doped with Si and Al atoms…

The paper presents a technique for solving numerically the nonlinear nonstationary problems of axisymmetric elastoplastic deformation of shells of revolution taking into consideration torsion under the large deformation. The method is based on the geometrically nonlinear Timoshenko theory of shells and the plasticity…
In practical geotechnical engineering the factor of safety is still determined by means of simple limit equilibrium analysis in many cases. However, because displacement finite-element analysis is routinely applied for assessing displacements and stresses for working load conditions, this technique is increasingly bei…
Diseased heart valves are commonly replaced by mechanical, bioprosthetic, or allograft heart valves. These replacements provide major improvements in cardiac function and quality of life, but have significant limitations and eventually require surgical replacement within 15-20 years. These risks are particularly promi…
In bilayer system, consists of ferromagnetic insulator, high spin orbit coupling normal metal (FM|NM), a new ferromagnetic resonance (FMR) damping that depends on varying the thickness of the normal metal observed. This new enhancement in the damping attributed to magnetic proximity effect (MPE) at the interface, whic…
