The article discusses the literary-critical and national political activity of the outstanding Ukrainian poet and states figure Yevhen Malaniuk, using a corpus of his literary-critical essays. The author analyzes the oeu...

First data on lichens of the Teteriv River Basin appeared in the second part of 19th century. First records of lichenicolous fungi in this area were published at the end of the 20th century. An annotated list of lichens ...

The mechanical alloys-composite MАs (Mg +10 % wt.Ti + 5 % wt.Y and Mg +10 % wt.Ni + 5 % wt.Y) were synthesized. The phase content, microstructure, the thermal stability, kinetics of hydrogen desorption from the MgH2 hyd...

The effect of the WC content and the sintering temperature, as the main technological factor, on the phase composition of TiC–xWC–5VC–18NiCr alloys was investigated by X-ray phase analysis. It was established that ...

This article deals with the urgent problem of teacher’s professional self-development at a higher educational institution, based on normative and acmeological aspects. In the process of achieving this goal – which is...

By the method of microarc oxidation for different types of electrolytes (which include KOH, Na2SiO3, Н2О2, NaOH, NaAlO2, Na5P3O10, NaF) and electrolysis conditions, multifunctional ceramic coatings on a magnesium alloy...

The paper is dedicated to the development of effective composite coatings with the use of carbon fillers of different morphology, their research, and application in the broadband frequency range. Electromagnetic loss stu...

The conditions of formation and properties of hybrid organic-inorganic composites based on epoxy polymer matrix and a mixture of magnetic and polymeric fillers are studied. Based on the study of physicochemical properti...

Based on many years of experience in the organization of the third stage of Ukrainian National Astronomy Olympiad, the authors of the article attempt to formulate general principles for the selection and compilation of a...

In this work the structure and corrosion behavior of quasicrystalline cast Al63Cu25Fe12 and Al63Co24Cu13 alloys in 5-% sodium chloride solution (рН 6.9–7.1) were investigated. The alloys were cooled at 5 К/s. The st...

The conductivity of the Li-containing Al-oxoferrite samples has been studied. Using Jonsher’s phenomenological approach, existence of 2 types of conductivity (electronic and ionic) in the above mentioned samples has be...

The structural and phase composition of boron-rich Fe–В–С alloys in the concentration range of 9.0–16.0 % В, 0.001–1.7 % С, Fe – the balance (in wt. %) was investigated in this work. The cooling rate of the...

The novel ternary compounds Tl4GdTe3 and Tl4DyTe3 ­- structural analogs of Tl5Te3 (Sp.gr.I4/mcm), were synthesized and identified by DTA and XRD methods. From powder XRD data, their crystal lattices parameters were calc...

Intergenotypic differentiation of trophic niche was studied in the system “apricot (Prunus armeniaca L.) - Cacoecia podana Sc.”. C. podana larvae, carried alternative Aes-1 genotypes, were found to prefer host plant ...

Rare earth (RE) ions activated ZnO thin films were prepared via sol-gel route and the thin films be categorized by various techniques. X-ray diffraction (XRD) studies display the hexagonal wurtzite structure of the prepa...
