We have conducted X-ray fluorescence and X-ray diffraction analysis of a series of cubic zirconia crystals stabilized with yttrium and gadolinium and doped with neodymium. The structure of the crystals under study has been refined, with the uncertainty factor being less than 3% for all the crystals examined. The depen…

Tomando como base la necesidad que tienen las micro y pymes metalmecanicas de ser cada dia mas competitivasy productivas se presenta un enfoque y revision de los factores mas relevantes que permiten generar ambientes concurrentes en las empresas y como estos afectan positivamente el desarrollo de construcciones soldad…
New classes of continuously metallic and 'dielectric-loaded' relief metamaterials (raised or indented sub-wavelength patterns on continuous, non-perforated metal surfaces) enable manipulation of reflected light intensity and phase in the visible-infrared range. Perfect absorption, colour control, field enhancement and…
The mixed-valent nature of nonstoichiometric ceria (CeO2-δ) gives rise to a wide range of intriguing properties, such as mixed ionic and electronic conduction and oxygen storage. Surface and transport behavior in rare-earth (samaria) doped and undoped ceria were investigated, with particular emphasis on applications i…
The concept of element and its applications to improving the human condition and understanding of the structure of matter (the radiation being a manifestation of the matter) plunging into the origin of civilizations. The efforts made along of decades have crystallized in the laws of Mendeleev and Moseley, the analysis…

The influence of titanium alloys structure and texture on titanium alloys PT-3vkt half-blanks failure is identified
Popular summary Parkinson's Disease is a disorder caused by brain that affects patients' coordination, movement as well as causing tremor. The onset of Parkinson's Disease is found to be the large fibrillar aggregates in the brain which consists mostly alpha-synuclein protein. The disease propagation has also been ass…
Aromatic trifluorovinyl ether (TFVE) monomers are the precursors for perfluorocyclobutyl (PFCB) aryl ether polymers and fluoroethylene/vinylene alkyl/aryl ether (FAE) polymers. PFCB aryl ether polymers are prepared by 2π + 2π cycloaddition of aromatic TFVE monomers. FAE polymers are prepared by nucleophilic addition o…
Photoluminescence (PL) technique has been put into use for analysing In2S3/MEH‐PPV heterojunction for the first time. Strong luminescence of the polymer absorber MEH‐PPV has been exploited here to predict the properties of the cell. The underlying theory is the dependence of PL intensity on quasi Fermi level separatio…
In the article the comparison between a method of definition of capillary characteristics of textile materials and a method of definition of washing ability of binary solutions of PEAHENS is presented. Surface active agents (surfactants) chemical compounds that are concentrated at the interface, cause a decrease in su…
In this work we discuss some concepts of quantum mechanics showing the result for the ground state energy of the infinite potential well that, together with elementary thermal physics concepts applied to semiconductors, help us to estimate the size of nanostructures. The energy value of the infinite potential well is…
Theoretical foundation of antiradon ventilation effectiveness rising at uranium mines is given. A number of aerodynamic nozzles which help to raise range and aerodynamical qualities of ventilation stream to carry radon from purifying bottoms out is suggested
Maleamic acids have been received by the interaction of diamines on the basis of alkilaromatic phenols and ethers of alkilen-bis-N-amino benzoic acid with maleic anhydride. New bismaleinimides with alkilaromatic bridges have been received by ring formation of maleamic acids with acetic anhydride. Physical and spectral…
The photophysical and photochemical properties of NaCu(CN)2 and KCu(CN)2 in bulk and doped in alkali halide hosts have studied. In addition, heterometallic interaction between d10-d10 (Cu(CN)2--Au(CN)2- and Cu(CN)2--Ag(CN)2-) and d8-d10 (Ni(CN)42--Cu(CN)2-, Pd(CN)42--Cu(CN)2- and Pt(CN)42--Cu(CN)2-) doped in alkali ha…
In this paper, the degradation behavior under hot water of the hemp fiber reinforced thermosetting resin composite materials was examined. Especially, the effects of drying condition for hemp fiber before molding on the mechanical property and degradation behavior of the composites were investigated. In composite mate…
Article describes methodic of determination of the limit strains of fracture in sheet materials in case of unibeaxial tension. Geometrical relaxation after fracture is taken into account. Results obtained are in use for calculation of Forming Limit Curves of sheet materials. FLC will be applied in calculation and frac…
Despite sufficiently high effectiveness of hydrogenation processes of purification of oil stock from sulfurous compounds, they have a few drawbacks, some of which are irreparable loss of valuable sulfur organic compounds during the process of hydrogenolysis, high cost of the process and usage of expensive catalysts. A…
Some embedding theorems for functions belonging to Sobolev spaces with mixed summability powers are proved.
