In chemical and medical research, recent methods combine the tools of nanotechnology, chemistry and biology in a way that introduces the most modern processes to current medical practice. The main blood plasma proteins – albumin and globulin and their amino acid sequences, are carriers of important information about h…
It is a common procedure to describe the fission-fragment mass distributions of fissioning systems in the actinide region by a sum of at least 5 Gaussian curves, one for the symmetric component and a few additional ones, together with their complementary parts, for the asymmetric components. These components have been…
This work describes the application of oxo-derivatives of fullerene C60 and pristine fullerene as a nanocomposite in polymerous nanofibres. In this work we used oxo- fullerene derivative, of which preparation was presented by the authors of the State office for nuclear safety (Prague) on Nanocon 2009 and on Nanocon 20…
Electron paramagnetic resonance (EPR) and optical absorption spectra of copper ions in xLiF-(50-x)Li2O-20SrO-30Bi2O3 glass system have been studied. MDSC studies showed that the glass transition temperature decreases with LiF content. Optical absorption spectra of the pure glasses reveled that the cut off wave length…
C-C bond fragmentation of structurally diverse carbocycles has been applied to the divergent synthesis of dendrimers. The fragmentation has been paired to deprotection or thio-Michael reaction, allowing the preparation of a fourth generation dendrimer of narrow molecular weight distribution. Methodologies to increase…
Abstract: In present work, the finite element method was used to simulate the whole process of nanoindentation test. Two kinds of indenters, spherical and conical, were used to simulate indentation test of concrete. The modeling procedures were introduced in detail. The agreement between the FE calculations and experi…
The photochemical and photophysical behaviour of metal complexes remains a primary reason for the continuing and increasing interest in their study by both established and more recently developed spectroscopic techniques. The diversity of spectroscopic properties arises in large part from population of the wide range…
A single catalyst can serve a dual role if it can be oxidized at the anode and reduced at the cathode. In an undivided cell, some of the oxidized species may reach the cathode, and some of the reduced species may reach the anode, and these two species may also react with each other in the middle of the cell. These pro…
The properties of medium density fibreboards (MDF) are amongst others influenced by the properties of the wood fibre pulp. One influencing property is supposed to be the surface roughness which is known to be important for the bond quality e.g. when gluing veneer and solid wood. At the Institute for Wood Technology Dr…
A hybrid approach to flnd the optical response of periodic photonic structures to incident light is presented. The approach is based on a scattering matrix combination of the Finite Element Method (FEM) and the Fourier Modal Method (FMM). Optical response calculations include: scattering in both re∞ection and transmis…
Abstract—It is established in this article that a special class of metamaterials known as hyperbolic media allow the propagation of large classes of novel monochromatic and pulsed localized waves. Illustrative explicit solutions are given of “accelerating ” oblique Airy beams, as well as nondiffracting and nondispersi…
Three new dicyanamide‐bridged polymeric complexes of {[Mn(dca)2(L)2] · 2H2O} n (1), {[Cd(dca)2(L)2] · 2H2O} n (2), and {[Co(dca)2(L)2]2(L)} n (3) (dca = dicyanamide, L = pyridinium‐4‐olate) have been synthesized and structurally characterized. In the three compounds, the protons of hydroxyl groups of 4‐hydroxypyridine…
This paper covers the study of destructive and non-destructive properties of weldments EN19 alloy steel using GTAW with non-pulsed current and pulsed current at different frequencies of 2Hz,4HZ & 6Hz.The radiography, liquid Penetrant test of weldments were evaluated and compared with pulsed and non-pulsed current weld…
Sugar phosphates provide metal-binding sites both at their sugar core and at their phosphate group(s). Mixed sugar-core-phosphate chelation has been considered as a typical bonding mode within the physiological pH range for the central metabolite D-fructose 1,6-bisphosphate. The Re(V)O(tmen) metal fragment was used to…
This study demonstrates computer simulation of human brain treated with interstitial microwave hyperthermia. A thin coaxial-slot antenna emitting microwaves is the heat source. For simplification, a 2D axisymmetric model is considered. The wave equation for TM wave case and the Pennes bioheat transfer equation for tra…
Circular braiding currently lacks automatic generation of optimum CNC code. A geometry-based procedure for braid angle optimization was designed and implemented for arbitrary mandrels.
Diffuse myocardial fibrosis is present in several cardiomyopathies. Contrast enhanced cardiac MR with T1 mapping enables quantification of diffuse fibrosis. T1 mapping is technically demanding since technical, physiological, and biochemical factors can interfere with T1 measurements. Contrast material dose, relaxivity…
The article presents the analysis of failure for a reinforced concrete beam with a low level of reinforcement, made of high strength concrete, in the process of static deformation in comparison to experimental results. On the basis of its ultimate uni� axial compressive strength, the methodology for defining the param…
Abstract—In this paper, we introduce a high order finite element (FEM) implementation using perfectly matched layer (PML) for the scattering by plasmonic structures inside layered media. The PML is proven to be very accurate and efficient by a comparative analysis with a commercial FEM software and the Multiple Multip…
This study focuses on the preparation of modified bis muth oxide photocatalysts using sonochemically assisted hydrothermal synthesis and photodeposition method. RuO2/Bi2O3 photocatalysts were doped with Cr and Ptto enhance their photocatalytic activity. The crystalline phase compositions and surface structures of thes…
