The article considers the question of physical modeling of stresses in a compound rotation body of a complex form with a complex loading distribution. According to the similarity parameters, the stresses, deformations and displacements caused by the volume forces are reduced proportionally to the similarity scale for…
Dust explosions take place when small particles of flammable material such as grain, wood, plastic, coal and metal are dispersed in air and ignited. An important research tool that is used for describing dust explosion characteristics is the Hartmann apparatus, where dust is dispersed by a pressure wave. This makes it…
In the last decade, information technology fundamentally changed the design activity and made significant adjustments to the development of design documentation. Electronic drawings and 3d-models appeared instead of paper drawings and the traditional form of the design documentation. Geometric modeling of 3d-technolog…
The studies were aimed at developing a less expensive and environmentally friendly catalyst than the currently used industrial catalyst CuCr 2 O 4 /Al 2 O 3 . CuO-Fe 2 O 3 -Al 2 O 3 systems prepared by fusing the nitrate salts were examined. The mixed oxides were characterized using a set of physicochemical techniques…
The core steel part “NAKAGO” in the hilt of the Japanese short sword “TANTO” was used. This sword was made by one sword craftsman. The surface of the core steel part was machined manually by him using some hardened files. After hand-filing, the filed mark lines were remained on the finished surface. In this study, the…
In a ferromagnetic resonance experiment, the frequency vs resonance field data is fitted to the resonance condition formula for extraction of the effective magnetization and gyromagnetic ratio of the ferromagnetic material under test. We found that the fitting may result in significant error in some cases. We studied…
Leaves extracts of Glycyrrhiza glabra was investigated as sustainable corrosion resister of mild steel in 3.5% NaCl by using polarization measurements, UV, IR and SEM study. This plant shows good corrosion inhibition efficiency at lower concentration of inhibitor. This plant extract act as a mixed type of inhibitor an…
New structural systems for civil and transport engineering were examined. The basis for the formation of the proposed reinforced concrete structures is the ideology of reducing its dead weight, with a given bearing capacity, the realization of which is accomplished by burial during concreting large-sized liners of a g…
One of the most important problems in socks manufacturing industry is change in size that affects the dimensions of final product. This dimension instability arises mainly due to the strains in the fabric getting relaxed during any wet treatment. Change in dimension play a vital role in achieving the required specific…
Seven triterpenoid derivatives were isolated from the roots of Calotropis gigantea (L) Dryand, a Chinese traditional medicinal plant. Their structures were established on the basis of their spectroscopic data and comparison with those in the literature. A new triterpenoid acetate derivative, compound 7, Calotropisis,…
Aggregates of non-convex particles have shown to be particularly stable which makes them good candidates to design new lightweight and reversible structures. However, few is known about the fundamental reason of their stability. In this paper we presents a novel experimental method to investigate the local structure o…
Aluminum and copper are two common metals and Al-Cu joints are commonly used in the power industry. Overlay joints of 3105 aluminum alloy and commercially pure copper were produced by FSW, microstructure and mechanical properties was investigated. A combination of optical and scanning electron microscopy is used to ch…
This paper proposes a novel non-destructive vision-based system to perform automated gender classification of silkworm cocoons for the purpose of improving the quality of egg production. Gender classification is achieved by discriminative learning on samples of male and female cocoons acquired from CSR2 and Pure Mysor…
NPs combined with cold exposure induced a stronger inflammatory response and influenced the plasticity and metabolism in white adipocytes, accompanied by more serious health hazards.
), barrier thickness (ranging from 2 to 10 unit cells), polarization direction (both positive and negative polarizations) and epitaxial strain (i.e., -3%, -2.5%, -2%, -1.5% and -1%) as variables. This shows that the FTJs can exhibit quite diverse polarization bi-stability due to the combined effect of the electrode an…
We assess subsurface damage in ground Silicon Carbide, by measurement of roughness evolution and material removal rate in sub-aperture finished spots, or by estimates via material property figures of merit or abrasive size used for grinding.
In this study Polyvinyl alcohol (PVA) and (3, 5, 10%)wt microcrystalline cellulose (MCC) were prepared using a solution-casting method. The films that were produced characterized with Fourier Transform Infrared Spectrometry, Differential Scanning Calorimetric, Tensile test, and Barrier properties. The results from FTI…
The synthesis was investigated of the artificial ceramic mullite-silicon-carbide binders and of the composite materials on their base. The rheological, physical and mechanical properties of the binders were studied. The regularities of the composites' compressing depending on the formation condition and on the initial…
The poor flowability of powders produced from raw lignocellulosic biomass may be an economically issue for the production of second-generation biofuels. Torrefaction is a pre-treatment step of the gasification process that improves the physical characteristics of biomass by making it more coal-like. Particularly, the…
High yield nuclear fusion operating in tokamak and stellarator need to heat plasma up to the required temperatures. As the confined plasma is overdensed, the electron cyclotron resonance heating (ECRH) is inefficient due to cut-off layer. A double mode conversion O-SX and finally electron Bernstein waves (EBW) O-SXB,…
