Ecological insurance programmes selected into the individual module of the insurance entities interaction in the general insurance system are considered. Development of the national ecological insurance system requires its governance model building based on the specific exploitation of certain natural resources and ha…
The knowledge society concept which originated from the information society concept is considered. A comparative analysis of two concepts is given. The shift of modern society focus from the problems of information accumulation and transfer to the knowledge production and social innovation that determine the future fo…
Bottling machines metering accuracy is considered. Key factors affecting bottling machines accuracy are discovered.
Mechanism of forming habit of the plants on basis of assumption that the basic process which enables growth and development of plants is water transmission through their capillary channels is considered.
It is well known that hopping of charge carriers via spatially and energetically distributed localized states is a primary transport mechanism in many disordered semiconductors and polymeric dielectrics. In this contribution, the nonlinear I-V physics of a 25 vol% 50 nm p-SiC/silicone rubber composite for high voltage…
The majority of contrast agents used in magnetic resonance imaging (MRI) is based on the rare-earth element gadolinium. Gadolinium-based nanoparticles could find promising applications in pre-clinical diagnostic procedures of certain types of cancer, such as glioblastoma multiforme. This is one of the most malignant,…
Experimental results of magnetocaloric effect for several polycrystalline and nanocrystalline manganites La1−xM0.xMnO3 (M=Ca and Sr) are analyzed. Influence of magnetic field is accounted for by the exponent N. The relatively deep N(T) minimum located close to the Curie temperature is found in the polycrystalline mang…
A facile, completely green, and cheap route for the synthesis of Au nanoparticles at 25–75° has been developed by using only hydrogen tetrachloroaurate as the precursor and gum arabic (GA) simultaneously as a reducing agent and a stabilizing agent. No extra reagents are needed. From the analyses of UV/VIS absorption s…
Wavelet shrinkage methods are effective for de-noising of partial discharge (PD) detection. Base wavelets are related to distortion of PD signals de-noised by wavelet shrinkage methods. This paper presents a scale dependent wavelet selection scheme for de-noising of PD detection. The scale dependent wavelet selection…
Abstract Electrospinning is a process used to fabricate continuous nanoscale fibers with diameters in the sub-micrometer to nanometer range using a high-voltage power supply. Electrospun (e-spun) fibers and the non-woven webs manufactured from them have attracted considerable attention due to their outstanding charact…
Capacitor technologies are as varied as the applications that they enable, but one of the common themes in advanced capacitors for consumer electronics is a desire for increased capacitance in smaller areas/volumes. The heroic advances of discrete capacitor manufacturers have kept pace with the increasing demands of m…
A simple and versatile method for making chemically patterned anisotropic colloidal particles is proposed and demonstrated for two different types of patterning. Using a combination of thermo/mechanical stretching followed by a wet chemical treatment of a sterically stabilized latex, both patchy ellipsoidal particles…
The incorporation and diffusion of helium (He) with and without intrinsic vacancy defects in cubic ZrO$_{2}$ are investigated through first-principles total-energy calculations, in which the projector-augmented-wave (PAW) method with the generalized gradient approximation (GGA) is used. The calculated formation energi…
We measure the thickness of the heavy water layer trapped under the stress corrosion fracture surface of silica using neutron reflectivity experiments. We show that the penetration depth is 65-85 ångströms, suggesting the presence of a damaged zone of $\approx$ 100 ångströms extending ahead of the crack tip during its…
Epitaxial growth of Ba0.6Sr0.4Ti1−xZrxO3 (0≤x≤0.3) composition spread thin film library on SrRuO3/SrTiO3 layer by combinatorial pulsed laser deposition (PLD) is reported. X-ray diffraction and energy dispersive x-ray spectroscopy studies showed an accurate control of the film phase and composition by combinatorial PLD…
Using density-functional theory with the on-site Coulomb correction (the local-density approximation plus $U$ method), we perform the structural optimization of ${\text{BiMnO}}_{3}$ by starting from different experimentally reported structures. We confirm that, irrespectively on the starting condition, all calculation…
Silver nanoparticles (Ag-NPs) were synthesized into the interlamellar space of montmorillonite (MMT) by using the γ-irradiation technique in the absence of any reducing agent or heat treatment. Silver nitrate and γ-irradiation were used as the silver precursor and physical reducing agent in MMT as a solid support. The…
phosphors are prepared using a convenient solid-state reaction route. The red emission intensity of is enhanced by ion codoping. The energy transfer mechanism from to was found to be a dipole-quadrupole interaction with a critical distance of . With increasing doping content, the energy transfer efficiency gradually i…

Using magnetron sputtering, we have prepared Co-Fe-B/tunnel barrier/Co-Fe-B magnetic tunnel junctions with tunnel barriers consisting of alumina, magnesia, and magnesia-alumina bilayer systems. The highest tunnel magnetoresistance ratios we found were 73% for alumina and 323% for magnesia-based tunnel junctions. Addit…
