Dissipation of characteristics of construction materials fatigue properties is caused by a number of objective factors. But this problem can be solved through developing and implementing into engineering practice effective mathemati-cal methods of analyzing experimental information. This paper considers optimum planni…
The work presented in this thesis investigates the growth and properties of group III- nitride semiconductors that were grown using the Migration Enhanced Afterglow Epitaxy (MEAglow) method. This work was to enhance the understanding of the MEAglow growth process towards the improvement of quality of the layers grown…
In article settlement ratios, results of an assessment of limit traction characteristics of independent valve-inductor engines, the experimental model of the semi-trailer of the road train and limit rises overcome by the experimental road train in the active and passive modes, in the mode of long rise, in the mode of…
The test is addressed to investigate the influence on stack durability of a long stop followed by a restart of a stack. Long stop should be defined as a stop in which the anodic compartment is fully filled by air due to stack leakages. In systems, leakage level of the stack is low and time to fill anodic compartment r…
A Python library for computing integrated information.
Bader's quantum theory of atoms in molecules (QTAIM) is used to evaluate local atomic stabilities in clusters of molecules. The total energy of a molecular system is decomposed into atomic contributions determined quantum mechanically through evaluation of the electron density contained within atomic basins. Stability…
found to be almost the same in each case. The presence of para-substituent causes very little change in the Na + affinity relative to the unsubstituted acetophenones. Electron releasing p-substituents are seen to increase the affinity, while electron withdrawing p-substituents have an opposite effect. The computed Na…
Nanocomposites of polyazomethines have been prepared via in situ and ex situ addition of Ag and PbS nanoparticles. Structural characterization of nanocomposites by X-ray diffraction shows formation of pure nanocrystalline Ag and PbS with cubic structure. Transmission electron microscopy gives evidence for spherical na…
The article considers the issues of ensuring the health of machine parts during operation using microcapsules containing polymer repair materials. Method of recovery of the parts during operation of transport and technological machines under repair polymeric material falling within the zone of damage resulting from th…
Numerical analysis was performed for compressive strength of the concrete. Internal defects of the concrete specimen were simulated and compressive strength reduction mechanism was studied. The defects inside of the specimen are stochastic; therefore it is impossible to study the subject with physical material testing…
Correction for ‘Antimicrobial effects of silver deposited on nanolayered manganese oxide’ by Mohammad Mahdi Najafpour et al. , RSC Adv. , 2014, 4 , 64688–64691.
This paper summarizes the contributions of a PhD focused on developing a set of numerical methods for the analysis of periodic diffractive optical devices such as holographic diffractive devices, thin film filters or diffraction gratings. For the rigorous and comprehensive analysis of these devices in optical waveleng…
Through uniaxial compression test, tensile splitting test and bending test, we have researched the three kinds basic mechanical behaviors of Reactive Powder Concrete (RPC for short) with different steel fiber volume contents at 0%, 1%, 2% and 4% respectively. According to the result, the tensile splitting strength is…
L'emergence des nanotubes de carbone a ouvert de nouveaux champs d'application dans le domaine des materiaux polymeres. L'ajout de ces charges carbonees au sein de polymeres permet la mise en œuvre de composites aux proprietes electriques optimisees. La conductivite de ces materiaux depend en grande partie de l'organi…
In this paper, the Maxwell's equations for the tensorial magneto-electric (ME) medium have been solved which in fact is the extension of anisotropic nonmagnetic medium. All of the dielectric permittivity, magnetic permeability and the ME tensors are considered. The transverse polarization is shown explicitly and the p…
This article discusses ways of building parametric series of heavy vehicles modular design based on communication between the parameters of modules and features heavy-duty vehicles, justified the choice of the base parameter and parametric series of heavy-duty vehicles of various types: semi-trailers, self-propelled p…
Abstract The CaTe‐In‐Te quasi‐ternary system is studied by differential‐thermal analysis, powder XRD, microstructure examination, as well as microhardness and density measurements.

Purpose. Development of multi-alloyed filler for abrasive wear-resistant composites. Methodology. The methods of microstructural, X-ray and energy-dispersive X-ray analyses were used to achieve research purpose. Micro-mechanical properties of structural constituents and abrasive wear-resistance of composites were dete…
The AlN/ZnO bilayer heterostructures were deposited on Si (100) substrate by thermal atomic layer deposition. X-ray diffraction results show that the crystallinity of polycrystalline ZnO layer is enhanced by amorphous AlN capping layer. Compared with ZnO thin film, ZnO/AlN bilayer with 10.7 nm AlN capping layer exhibi…
