The aim of this paper is to investigate the influence of a thermoplastic stitched reinforced tape location in the seam, on seam slippage, seam strength and seam efficiency. Seam samples without reinforcement and reinforced with a fused tape were prepared. All the samples were prepared with 1.2 cm seam allowance. The s…
By changing the measurement temperature ( T ), one can vary the effective sample size so as to study the renormalization group (RG) (or T -driven) flow of a semiconductor, a topological insulator, or a graphene device in the complex conductivity plane.
The Transformer sustains various types of faults while in the working condition. There will be changes in electrical, mechanical and chemical properties in different parts of transformer before its failure. These changes in properties can be monitored by different condition monitoring methods. With proper analyzing th…
Most of the distribution systems are nowadays upgraded to underground systems. Cross-linked polyethylene (XLPE) insulation has been employed as an insulator in underground power cables due to its excellence in electrical properties. The environmental issues in service have been the major studied problem that associate…
The traditional way of manual cleaning stairs, not environmental protection, cleaning efficiency and low, cleaning workers time and labor, in order to solve this problem, the design of a low power MSP430 series single chip staircase. The cleaning machine realizes the combination of the triangular roller and the ordina…
This paper considers the NERA and EERA programs in detail. These programs are used to calculate expected seismic effects on construction sites. Scientific publications and normative documents cover the calculation problems of seismic effects only partially. This significantly complicates both the calculations and asse…
Corrosion of reinforcement is the most common type of deterioration of reinforced concrete structures and bridges. Serious degradation of the mechanical properties of reinforcing bars is because of corrosion. Pitting corrosion is the main form of corrosion. The nonlinear stress-strain behavior of corroded reinforcing…
We address the analysis of the Souza-Auricchio model for shape-memory alloys in the finite-strain setting. The model is formulated in variational terms and the existence of quasistatic evolutions is obtained within the classical frame of energetic solvability. The finite-strain model is proved to converge to its small…
Nanocomposites of different concentrations of cadmium sulfide nanoparticles in a polyacrylamide shell were obtained as a result of the reaction of cadmium nitrate with acrylamide and a tiosulfiding agent (thiourea) in certain stoichiometric ratios followed by thermal polymerization of the reaction mixture. The samples…
This study focuses on the occurrence of bubble nucleation in a liquid confined in a nano scale confinement and subjected to rapid cooling at one of its wall. Due to the very small size scale of the present problem, we adopt the molecular dynamics (MD) approach. The liquid (Argon) is confined within two solid (Platinum…
This paper presents experimental, analytical and numerical study of impact perforation of steel plates with the aim to develop the procedures to assess the perforation of steel against tornado-generated missile impact. In the experiment, flat plates of SS400 steel and SUS304 stainless steel were perforated by a square…
For the first time the paper determines thermophysical properties (specific heat capacity, thermal diffusivity, and heat conductivity) of the full-scale corium of the fast energy nuclear reactor within the temperature range from ~30°С to ~400°С. Obtained data are to be used in temperature fields calculations during mo…
In this study, an initial system design method for non-rotationally symmetric imaging systems is introduced. A three-mirror Yolo telescope with small f-number is initially designed and freeform surfaces are applied to improve the resolution.
In this paper a dataset containing biological variables of the water column of several Portuguese reservoirs is analyzed. Hierarchical cluster analysis is used to obtain clusters of phytoplankton variables of the phylum Cyanophyta, with the objective of validating the classification of Portuguese reservoirs previewly…
Square-planar diamagnetic nickel(II) complexes 5a and 5b containing 16-membered diamino-diimino ligands were prepared from the corresponding open-chain complexes 2a and 2b via condensation with o-phthalic dialdehyde in methanol. The solid-state structure of the starting complex 2b revealed the cisoid conformation of a…
Single crystals of MoS2 doped with gold (MoS2: Au) have been grown by the chemical vapor transport method using iodine as a transporting agent. The transmission electron microscopy (TEM) images showed that doping sites and migration behaviors of Au atoms moved around the MoS2 and jumped with different positions. The d…
Dissolution of the UO2 matrix is one of the potential routes for radionuclide release in a future deep geological repository for spent nuclear fuel. This doctoral thesis focuses on interfacial reac ...
The effects of small additions of tin, zinc, calcium and boron oxides on phase composition and electrical conductivity of zirconia-10 mol% scandia were investigated. Compounds containing 1 mol% zinc, tin and calcium oxides and 1, 3 and 5 wt.% boron oxide were prepared by solid state reaction and characterized by X-ray…
In view of the geological setup and the long-standing mining history of the Gauteng Province, South Africa, it is expected that the mine dumps around the gold mines could contribute to a significant radium (226Ra) concentration in water in Gauteng Province. Radium decays to its daughter radioisotope radon (222Rn) whic…
In this paper we have analysed the thermal, physical and optical properties of three different compositions of Chalcogenide glasses ie Ge20Se70Sb10, Ge25Se65Sb10 and Ge30Se60Sb10 glasses. The compositional dependence on properties were studied using absorption measurements, Differential Scanning Calorimetry (DSC) anal…
