The structuring processes of ferromagnetic disperse systems in the magnetoliquefied layer affected by the variable inhomogeneous and continuous magnetic fields with mutually perpendicular power lines are studied.
The theoretical and analytical basis of the economic assessment technique for the ecological policy and environmental policy actions results as regards to the sustainable development promotion is offered.
Some dangerous, in terms of the man-made ecosystem operation, events in the hospital environment are presented. The microbiological factor, its transformation in the course of the diagnostic and treatment process, and human health implications are considered.
The issues concerning the potential application of Markov processes theory for efficient management decision making based on the production enterprise business modeling are considered.
The issues on the mathematical description of the workpiece surface forming pattern generation under the vibration cleaning are considered. The probability that the predetermined point within the specific area has been cleaned is calculated. The mathematical expectation of the workpiece random area by the particles of…
A new type of the higher school education space is considered. The conceptual and terminological framework for its description is presented. The authors’ classification of the student competences developing the integrative phenomenon – competency – is proved.
The current state of the business meeting industry, the rate of delivery and performance features of MICE industry at the national and regional levels are analyzed. It is concluded that amid the growing globalization, business tourism acts as an innovation development source and as a catalyst for the socioeconomic dev…
Fault models of the artificial neural network hardware implementations are considered. The development of the neuroelement fault classes through the introduction of the additional neuron fault model class causing certain level signals appearance on their output in the interval (0,1) is offered. The experimental resear…
High technological effectiveness of the seed refiner, which permits to get seed grain in one clearing cycle and which includes an effective separation of the primary treatment and an effective separation of the seed treatment, is proved.
The stages of building the model of a graduate within the framework of the third generation standards are considered. A possible algorithm for building a competency model of 150700 “Engineering” degree program graduate, ‘Welding Engineering Technology and Equipment’ profile, based on the special competence analysis, i…
General laws of self-organization, certain features of the integral systems, relationship of the socioeconomic and socio-educational systems development in their unity, similarity and difference, are considered.
Kondo insulator FeSb2 with large Seebeck coefficient would have potential in thermoelectric applications in cryogenic temperature range if it had not been for large thermal conductivity κ. Here we studied the influence of different chemical substitutions at Fe and Sb site on thermal conductivity and thermoelectric eff…
We present the electrical transport characteristics of a batch of nano-crystalline diamond films of varying nitrogen concentrations and explain the conduction mechanism by the disordered quasi-superlattice model applied to semiconductor heterostructures. Synthesized by the hot-filament chemical-vapour deposition techn…
Fractoluminescence experiments are performed on two kinds of silicate glasses. All the light spectra collected during dynamic fracture reveal a black-body radiator behaviour, which is interpreted as a crack velocity-dependent temperature rise close to the crack tip. Crack velocities are estimated to be of the order of…
We investigate theoretically the magnetic dynamics in a ferroelectric/ferromagnetic heterostructure mediated by a strain-induced magnetoelectric interaction. The epitaxial strain involves a strong piezoelectricity and interfacial magnetoelastic coupling, the interplay of both gives rise to an electrically tunable unia…
Scanning transmission electron microscopy in combination with electron energy-loss spectroscopy is used to study LaNiO3/LaAlO3 superlattices grown on (La,Sr)AlO4 with varying single-layer thicknesses, which are known to control their electronic properties. The microstructure of the films is investigated on the atomic…
Pb1-xCaxTiO3 perovskite crystalline structure with x = 0, 0.2, 0.6, 0.7, and 0.8 were prepared by mixture method. The ac conductivity and dielectric properties of the studied bulk compositions have been investigated in the frequency range 1 10 3 5 10 6 Hz and temperature range 303473 K. The experimental results indica…
Investigations into carbon nanotube fibers as not only structural reinforcement materials but also standalone or embedded strain/damage, thermal, atmospheric and biochemical sensors are driven by their high specific strength, stiffness, electrical and thermal conductivity, and extreme flexibility. With future applicat…
BACKGROUND: Cell therapy is an emerging and exciting novel treatment option for cardiovascular disease that relies on the delivery of functional cells to their target site. Monitoring and tracking cells to ensure tissue delivery and engraftment is a critical step in establishing clinical and therapeutic efficacy. The…
In this paper, we report a non-equilibrium molecular dynamics study on the size-dependent thermal conductivity in single-walled carbon nanotubes with lengths up to micrometers at room temperature. It is found that the size-dependent thermal conductivity of single-walled carbon nanotubes can be described by κ(L,d)≈κg(L…
