The possibilities of using organic materials which based on the plant material as adsorbents for the elimination of oil pollution are presented in the pape
In this paper was carried out a brief overview of the current state of the problem and analysis of publications on it. The aim of this article is to adapt the method to calculate the energy balance oscillators with variable mass under the action of dry friction force. First we considered the problem of the oscillator…
The applicability of the classical fracture criteria for the evaluation of the limit state and the fatigue life-time of solid prismatic specimens under combined loading by axial tension-compression with torsion and bending with torsion. The criterion of maximum normal stresses, the criterion of maximum shear stresses…
Methodic and experimental investigation results of pine wood (Pinus sylvestris L.) hygroscopicity limit and diffusion coefficient are described
UKR: У статті представлено результати експериментального дослідження часових залежностей напруженості магнітного поля та магнітної індукції в циліндричному зразку магнітного матеріалу під час його імпульсного намагнічування. Імпульсний метод намагнічування зразків магнітотвердих матеріалів є одним з перевірених ефекти…
Calculations of wave guide were carried out for strengthening surface of fan airfoil wide chord in ultrasonic field. Based on calculation results the above wave guide was manufactured, tested and features stable operation at design parameters.

This paper is a further development of the local gradient approach in thermomechanics. The presented model allows us to study the stress-strain state of nanoelements under one-continuum approach. Thermoelastic body is considered as an open thermodynamical system where the mass fluxes and sources are connected with sud…
Tensile static tests of carbon fiber reinforced composite laminates (CFRP) with a machined notch and an impact notch penetrated by a foreign object were conducted and non-destructive and destructive inspections of the damaged specimens were done to understand the failure mechanism and the effect of initial damage on t…
Описаны варианты изготовления неметаллических контрольных образцов для капиллярной дефектоскопии. На одном образце реализовано несколько трещин, соответствующих разным классам чувствительности. Положительный эффект достигнут созданием основы из неметаллического материала - эпоксидного клея, в котором дефекты выполнены…
In this research, the effect of inclusion of as-received graphene nanoplatelets, and chemically modified graphene nanoplatelets (i.e., graphite oxide (GO) and silane-functionalized (Si-G)), on the fracture toughness of epoxy resin and mode-I interlaminar fracture toughness of glass fiber-reinforced epoxy laminates are…
The analysis and design of electromechanic devices involve the solution of large sparse linear systems, and require, therefore, high performance algorithms. In this paper, the Schur complement method with a parallel preconditioned conjugate gradient (PCG) solver is introduced into two-dimensional parallel time- steppi…

A model for the assessment of impact of major structural and technological parameters of the aircraft structural hinge assemblies on fatigue life of joint subassemblies considering excess bending stress coefficient of the joint subassemblies is proposed and implemented. During the test of actual assemblies under skew-…
Рассчитаны константы диссоциации по кислотному и основному типу пространственно экранированных производных 4,6-ди-трет-бутил-2,3-дигидроксибензальдегида на основании результатов их потенциометрического титрования. Установлено, что в водно-этанольном растворе данные соединения образуют комплексы с ионами Mn(II), Fe(II)…
The results of investigations of the peculiarities of using the modular-design analysis of clamping devices, used for calculation of forces acting upon clip various ways of preparation in the process of its processing on metal-cutting equipment
This paper explores the possibility to use carbon nanotube (CNT) networks for the development of a structural health monitoring (SHM) technique for large polymer composite structures (LPCS) made of electrically non-conductive fibers and CNT networks using electrical resistance measurement (ERM). The effects of distanc…
The purpose of this study is to construct frame structure of continuous fiber reinforced thermoplastic composites with high impregnated intermediate materials and the high cycle molding. For the continuous straight pipe, pultrusion systems by using braiding technology with fibrous intermediate material were employed.…
Such special properties of phosphates as their photo- and electro luminophoric, catalytic, ferroelectric, and electret activities are developed in the result of a specific structure formation having stable enough by mechanical and thermal characteristics and simultaneous containing useful defects and highly mobile ion…
In this study, different types of magnetic nanoparticles were synthesized for treatment of breast cancer by targeted drug delivery. Polyamidoamine (PAMAM) dendrimer, Chitosan (CS) and Polyhydroxybutyrate (PHB) coated magnetic nanoparticles were prepared and loaded with Gemcitabine. The loading efficiency of drug for v…
