Metal Matrix Composites (MMCs) have shown great interest in recent times due to its potential of applications in aerospace and automotive industries because of having superior strength to weight ratio. The wide use of particular metal matrix composites for engineering applications has been obstructed by the exact use…
This paper deals with the analytical investigation of convection in a passive mushy layer under the influence of inertial effects, formed during the solidification of a binary alloy melt. The mush-solid interface is at a eutectic temperature while the mush-liquid interface is impervious. Analytical solution for the ba…
The method of the determination of the rational performance characteristics of the thermotransformer for cooling the air at the inlet of regenerative gas turbine unit (GTU) with heating the compressed air before combustion chamber by turbine exhaust gases has been suggested. The method enables calculating the rational…
Atorvastatin happens to be a potential inhibitor of HMG-CoA reductase involved in the synthesis of cholesterol and is being used to decrease the low-density lipoproteins in blood. The drug has profound effect, but the dosage is high compared to other statins. Therefore, it was thought to minimize the frequency of dose…
The hypothesis about the nature of control is a method of processing a magnetic field cutting and deforming tools based on the analysis of operating experience and experimental studies of a wide range of instruments. To study the influence of magnetic field on the adhesion process is proposed and used atomic-electroni…
Using optical electromagnetic fields in dielectric microstructures, we can realize higher-energy accelerator systems in a more compact, low-cost form than the current state-of-the-art. Dielectric, laser-driven accelerators (DLA) have recently been demonstrated using fused silica structures to achieve about an order-of…
The nanostructured SnO 2 thin films were prepared by spray pyrolysis technique. The cigarette smoke sensing performance of these films were systematically studied. The results reveal that the nanostructured SnO 2 sensor has enhanced sensing properties to 10-80 ppm cigarette smoke at room temperature. The instant respo…
Comprehensive understanding of beam losses in the LHC is required to ensure full machine protection and efficient operation. The existing BLM system using ionization chambers is not adequate to resolve losses with a time resolution below some 10 us. Ionization chambers are also not adequate to measure very large trans…
We consider a model originally introduced to study layer-undulated structures in bent-core molecule liquid crystals. We first prove existence of minimizers, thenanalyze a simplified version used to study how in columnar phases the width of the column affects the type of switching, which occurs under an applied electri…
Thin films of NiSe (nickel selenides) were prepared at different concentrations in the range 0.50 M to 1.00 M with the other deposition variables such as the bath temperature, pH, and source to substrate distance kept constant. The films were characterised using optical spectroscopy to investigate the absorbance, refl…
This study aimed to develop equipment to sail cloth life cycle assessment. Analytical screenings of testing sample were carried out using FTIR (Fourier Transform InfraRed), SEM (Scanning electron microscope-desktop) and VIVID 9i (3d laser scanner). The comparison between virgin and discarded materials was used to vali…

近年，人工材料の概念に基づくメタマテリアルの研究が進んでおりマイクロ波デバイスやアンテナへの応用に広がっている．本稿では最近のメタマテリアル研究のトピックの中から，変換電磁気学に基づく任意の物体と同じ散乱波を持たせたイリュージョンクローク，Γ点において群速度が非零となる分散特性を人工的に実現したディラックコーンメタ表面，フォスターのリアクタンス定理に従わない負のキャパシタンスや負のインダクタンスを実現するノンフォスター素子，及びフェライトを利用して位相の非相反性を実現した非相反メタマテリアルを紹介する．
A study was conducted to investigate the influence of microbiological activity on different quality factors of fruit and vegetable during storage. The fresh produce samples were collected from modified atmosphere packaging shed and assayed by enumerative tests for total aerobic bacteria, total coliforms and Escherichi…
East Japan Railway Company (JR East) installed an energy storage system using lithium-ion batteries for more effective regenerative energy utilization to the Haijima substation on the Ome Line and the Okegawa substation on the Takasaki Line and started its operation in February 2013 and March 2014 respectively. It is…
The orthorhombicity of martensitic structure in Ti alloys can be explained by an anisotropy of pair correlations due to short-range ordering (SRO), as proposed by Cahn and Rosenberg. We use firstpr ...

It has been shown that the reduction of the real anisotropy of carbon nanotubes (nanofilaments) in polymer nanocomposites on increase in the nanofiller content is due to the structural factor, namely, the formation of ring-shaped structures of the indicated nanofillers. The reduction of the anisotropy degree leads to…
CNT growth can change the fiber processibility and affect the composite meso-microstructure, its properties. We study the effects of grown, radially aligned CNTs on the textile composite architecture.
A model of service life, taking into account the activation energy of the aging process, the intensity of exposure to ultraviolet radiation, temperature and humidity. Is shown by the example of the method of calculating the life of coatings according to the accelerated tests
