The purpose of this work is perfecting the design processes of template equipment in the conditions of aircraft production due to the development of complex means for support the design decisions based on the principles of classification. Now design process of electronic models of template equipment is carried out by…
Faculty Mentor: Jeffrey Catalano Organic acids, such as the complexant oxalate and the reductant ascorbate, and iron oxides, like goethite, occur naturally in soil systems. Metals, including zinc (Zn), also exist in the soil and serve as a micronutrient in small quantities and a contaminant in larger ones. The relativ…
The authors prove the necessity for working out radical decisions for the design standards revision taking into account technological advances, in particular the development of nonlinear methods of structures, including complex stress conditions, new proposals for calculating the reliability, survivability, structural…
Environmental degradation of rubber is distinguished from each other based on the intensity of the imposed radiation energy. Oxide only changes properties of rubber without influencing its fracture and life. Ozone and ultra-violet of high energy radiation induce directly the initiation and propagation of crack and thu…
Culture of autologous cell sheets is one of the promising methods in regenerative medicine. Cultured epidermis is used for the coverage of massive burn wounds and cultured periosteum is for the treatment of infrabony periodontal defects. In cell sheet engineering cardiomyocyte sheets prepared with temperature–responsi…
To eliminate the existing shortcomings of reciprocating internal combustion engines around the world for a long period of engines were and continue to be carried out intensive research to improve them. The main feature is that the causes of the imperfection of piston engines built into the structure itself and in esse…
非平衡プラズマによる低濃度VOCの効率的な処理を目的として，BaTiO3, α-Al2O3の2種類の誘電体粒子 (平均粒径1mm) を充填したプラズマ反応器を用いたアセトアルデヒドの分解実験を行った。その結果，BaTiO3充填，印加電圧10kV以上の条件で，アセトアルデヒドの分解率は95%以上に達し，主な生成物としてCOおよびCO2が検出された。アセトアルデヒドの分解は電子あるいはラジカルとの反応により起こり，大部分はCO2へと転化されるが，印加電圧を増加するとCO2の一部はCOに分解した。また，加湿・低印加電圧条件ではアセトアルデヒドの分解は阻害されるが，無機化率およびCO2選択率は増大した。これはH2Oと電子の反応によりアセト…
By researches it is established that improvement of quality of connections of a ftoroplast-4 with metals is provided with application of ultrasonic fluctuations (UZK) with a frequency of 2 MHz. Intensity of UZK and time of scoring of a zone of welding which provide increase of durability of connection ftoroplasta-4 wi…
This paper reports on the structural and electrical properties of LiPO3 glass over a wide range of frequencies (10 Hz-2 MHz) and temperatures (290 K- 627 K). The temperature dependence of a.c. conductiv- ity is studied at dierent frequencies. The d.c. conduc- tivity is due to the hopping of lithium ions. A theoreti- c…

Trabajo presentado a la 5th International Conference on Biobased and Biodegradable Polymers, celebrada en Donostia-San Sebastián (España) del 6 al 9 de octubre de 2015.
Multicomponent system is the basis for the development of compositions with desired properties. Previously, the study of topology of multicomponent systems was carried out using graph theory (method of indices of vertices). Due to the complex topological structure of component relationships, the study of such systems…
We consider the problem of stress-strain state of soft shells under the action of the mass and the surface load. In the plane case, it is also allowed that the shell may be restricted in the movement by obstacles. Generalized statements are stated as variational and quasivariational inequalities. Solvability of the pr…
Objective: To develop a method for calculation and experimental studies of bodies of modern carriages manufactured from new corrosion-resistant steels. Methods: Finite elements method was used for calculational evaluation of carriage body strength, from which a parameter-orientated fi nite-element model using SCAD int…
Based on mathematical analysis and developed computer program it was studied the influence of effective concentration of the cross-links in the high rubber polybutadiene on ultimate mechanical properties (rupturing stress and strain) under uniaxial tension. Stress-strain diagrams at different temperatures and the stan…
The application of the fire-retardant heat-insulating coatings the application of light fillers is considered the effective method of fire protection of structures. Work is dedicated to the development of the new effective cement fire-retardant and high-temperature (oxidation-resistant) vermikulitobetonnykh composites…
In this article the problem of receiving high-quality cast strips from the magnesium alloys received by units of twin roll casting process in the combined methods is discussed. Production of sheets from magnesium alloys combination of casting and rolling at continuous giving of liquid melt to the rotating rolls is per…
Chemical decomposition of the CZTS surface during annealing is detrimental to device performance. Aiming to obtain more flexibility in the annealing process the surface is protected by a thin CuS cap.
The purpose of this project is to study the effect of helix-breaking residues on a single pass transmembrane ?-helical peptide, Poly(LA)7 in aqueous and lipid environments. This was achieved by creating four substitutions containging either Glycine or Proline: the mutated peptides contained single or double substituti…
