Studying awareness, importance, satisfaction, and wearing behavior of functional textiles for active silver generation related with gender and age is expected to contribute to clothing products development to improve and maintain their health and marketing strategy fit for user characteristics. For empirical research,…
Temperature responsive polymers such as Poly (N-isopropylacrylamide) (PNIPAM) have been shown to have potential to improve water recovery from mineral tailings by using the polymer as a flocculant at temperature above the lower critical solution temperature (LCST 32°C) and then as a consolidation aid at temperature be…
Bu calismada teknik polyester ipliklerin, kopma mukavemetlerinde onemli bir azalmaya yol acmadan hava-jetli teksture edilmeleri incelenmistir. Calismada kullanilan asiri besleme oranlari iplik mukavemeti icin gerekli olan liflerin paralel konumlanmalarini korumak icin dusuk tutulmustur. Liflerin yuzeyleri elektron tar…
Size reduction of high energy materials such as 1, 3, 5, 7-tetranitro- 1, 3, 5, 7-tetraaza cyclooctane (HMX) has considerable influences on improving their explosive characteristics. In this study, nanosized HMX particles were produced using ultrasonically reprecipitation method by applying water as a safe and access…
Inhibitive and adsorption properties of ethanol extracts of leaves of Solanum melongena (SM) were studied using gravimetric, gasometric, thermometric and FTIR methods. The results obtained indicated that the ethanol extract of leaves of SM is a good adsorption inhibitor for the corrosion of mild steel in HCl solution.…
In order to study the material characteristics, it is essential to obtain the quantitative description of micro-structure of the materials. In this context, digital image processing is used to analyze the microscopic images of the materials. Extraction of grains/phases present in the material is the fundamental step t…
This paper employs a single-phase unified quality conditioner (UPQC), an integration of shunt and series active filters (APF), to perform voltage and supply current harmonics mitigation and power factor correction. Both the shunt and series APFs are realized using a single-phase, two leg voltage source inverter (VSI).…
Within the scope of the self-consistent-field (SCF) and mean-SCF (MSCF) approximations, static-concentration-waves and Matsubara-Kanzaki-Krivoglaz lattice statics methods, on the basis of state-of-the-art diffraction data concerning coherent and diffuse scattering of radiations in (dis)ordered f.c.c.-Ni-Fe alloys for…
This paper deals with analysis of power signals using complex wavelet transform. In the first step power signals containing sag, swell, harmonic, sag-harmonic, swell harmonic, transient and spike were generated using Matlab. Various features like energy, kurtosis, entropy, skewness etc. were extracted using `db4' and…
Phytochemical investigation of Hylodendron gabunensis resulted in the isolation of two new glyceride derivatives, hyloglyceride (1) and hylodiglyceride (2). The structures of the two new compounds were determined by comprehensive analysis of their 1D and 2D NMR spectroscopic, and HREIMS data. One known compound was al…
The objective of the research was to compare the porosity/compactness of the knitted structures made from viscose and polyacrylonitrile yarns with incorporated elastane and without elastane, respectively, and to evaluate the elastane addition impact to their moisture management and air permeability properties. The add…
Topological diagrams are constructed for all layered and framework beryllosilicates and for zeolites having related topological features. These diagrams are used to identify the secondary building units (SBU). The SBU are arranged in increasing order of ring dimension to establish a structural hierarchy for this chemi…
Shot peening is a cold working process by which residual compressive stresses are induced in the surface and near-surface region to increase the fatigue strength and the resistance to stress corrosion cracking This study covers non-destructive evaluation of surface residual stresses in the shot peened steel components…
Abstract Guanidine and imidazole are important functional molecules that constitute the side chain of basic amino acids (arginine and histidine); these molecules are capable of interacting with mineral surfaces. However, little information is available about the effect of these molecules on mineral dissolution, includ…
Abstract NEWMOD®, developed by R.C. Reynolds, Jr., has been an important tool for evaluating quantitatively X-ray diffraction (XRD) patterns from interstratified clay minerals for more than 20 years. However, a significant drawback to the NEWMOD® approach is that analyses are done by forward simulation, making results…
Article Cold-sprayed Coatings based on High Strength Aluminium Alloys Reinforced By Quasicrystalline Particles: Microstructure and Key Properties was published on December 1, 2010 in the journal High Temperature Materials and Processes (volume 29, issue 5-6).
Triggering characteristics of triggered vacuum switch (TVS), including the discharge delay time, delay jitter, range of operational voltage and peak of pulsed current, are investigated. Both structure and experimental circuit of TVS are presented. The results indicate that TVS, as a surface flashover triggering device…
AIM: To study the ultrastructure and some functional indexes of tumor cells treated with stabilized iron nanoparticles in vitro. METHODS: 3-[4,5dimethylthiazol-2-1]-2,5-diphenyltetrazolium bromide (MTT)-test, electron microscopy, polarography with applying of closed Clark's electrode. RESULTS: It was shown that cultiv…
This paper studies in detail the electronic properties of the semimetallic single-walled carbon nanotubes by applying the symmetry-adapted tight-binding model. It is found that the hybridization of π—σ states caused by the curvature produces an energy gap at the vicinity of the Fermi level. Such effects are obvious fo…
Holographic lithography coupled with the nonlinear response of photoresist to the exposure is adopted to fabricate porous photoresist (PR) mask. Conventional dot PR mask is also generated, and both patterns are transferred into a underlying GaAs substrate by the optimal dry etching process to obtain tapered subwavelen…
