In this study, the effect of corrosion on the static behavior of stud shear connectors was investigated. Two series of push test specimens having different stud diameters were fabricated according to Eurocode 4. The test specimens were first corroded to different corrosion rates by electronic accelerating method. Stat…
The advent of friction stir welding (FSW) in 1991 has been evolutionary in the joining of metals and related materials. Friction stir welding has enabled the joining of metals that could not be joined by other welding processes. Research has shown that dissimilar materials with very different properties, plastics, com…
Nanotechnology is a most promising field for generating new applications in medicine, although, only few nano products are currently in use for medical purposes. A most prominent nanoproduct is nanosilver. Nano-silver has biological properties which are significant for consumer products, food technology, textiles, and…
So far, coumarin dyes have been extensively studied with various means to understand their photophysical behaviors and photochemical properties. Here, our performing time-dependent density functional theory calculation is aimed at exploring the excited-state hydrogen bonding dynamics of coumarin 153 (C153) in protic e…
Control of zero-field spin splitting is realized in a dual-gated high-quality InAs-AlSb two-dimensional electron gas. Magnetotransport experiments showed clean Shubnikov--de Haas oscillations down to low magnetic fields, and the gate-tuned electron mobility exceeded $700\phantom{\rule{0.16em}{0ex}}000\phantom{\rule{0.…
Implant failure due to poor integration of the implant with the surrounding biomaterial is a common problem in various orthopedic and orthodontic surgeries. Implant fixation mostly depends upon the implant surface topography. Micron to nanosize circular-shaped groove architecture with adequate surface roughness can en…
We consider planar bar-and-joint frameworks with discrete point group symmetry in which the joint positions are as generic as possible subject to the symmetry constraint. We provide combinatorial characterizations for symmetry-forced rigidity of such structures with rotation symmetry or dihedral symmetry of order 2 k…
There has been considerable improvement in cancer survival rates, primarily through improved preventive strategies and novel anticancer drugs. Cancer is now becoming a chronic illness and as such both short and long-term cardiotoxic effects of cancer therapy are becoming more apparent. This has led to the emergence of…
Bismuth telluride (Bi 2 Te 3 ) is one of the most important commercial thermoelectric materials. In recent years, the discovery of topologically protected surface states in Bi chalcogenides has paved the way for their application in nanoelectronics. Determination of the fracture toughness plays a crucial role for the…
Scrapie in goats is a transmissible, fatal prion disease, which is endemic in the British goat population. The recent success in defining caprine PRNP gene variants that provide resistance to experimental and natural classical scrapie has prompted the authors to conduct a survey of PRNP genotypes in 10 goat breeds and…
We delineate the optimized growth parameter space for high-uniformity catalyst-free InGaAs nanowire (NW) arrays on Si over nearly the entire alloy compositional range using selective area molecular beam epitaxy. Under the required high group-V fluxes and V/III ratios, the respective growth windows shift to higher grow…
We present a new algorithm to solve the polarizable continuum model equation in a framework compatible with the strategy previously developed by us for the conductor-like screening model based on Schwarz's domain decomposition method (ddCOSMO). The new discretization is systematically improvable and is fully consisten…
Polyacrylonitrile precursor fibers prepared using a solvent-free coagulation process were stabilized, carbonized, and physically activated bycarbon dioxide into activated carbon fibers (ACFs). The activation temperature varied from 600 to 900?C while the activation time was 1 h. Atomicforce microscopy was used to obse…
OBJECTIVE: To observe effect of compound Kushen injection on T-cell subgroups and NK cells in patients with locally advanced non-small-cell lung cancer (NSCLC) treated with concomitant radiochemotherapy. METHODS: We randomly divided 60 patients with locally advanced NSCLC who were treated at our hospital between May 2…
In the large polaron model of Herbert Fröhlich, the electron-phonon interaction is a small perturbation in form sense, but a large perturbation in operator sense. This means that the form-domain of the Hamiltonian is not affected by the interaction but the domain of self-adjointness is. In the particular case of the F…
In this study, monodisperse polystyrene nanospheres were prepared by dispersion polymerization using alcohol as reaction medium to prepare colloidal clusters of the latex beads. Polyvinylpyrrolidone (PVP) and 2-(methacryloyloxy)ethyltrimethylammonium chloride (MTC) were used as dispersion stabilizer and comonomer, res…
engine has a predominant role in a low power generation and a virtual monopoly in mobile applications today. One of the best methods to improve the engine performance and reduce the exhaust emission in a SI engine is by using introduction of twin spark into the combustion chamber. Two stroke spark ignition engines hav…
Structural life assessment periodically evaluates the state and condition of a structural system and provides recommendations for possible maintenance actions or the end of structural service life. It is a diversified field and relies on the theories of fracture mechanics, fatigue damage process, probability of failur…
he negative differential capacity has been observed in case of MIS structures with SiOx and SixOyNz films containing Si nanoclusters. It has been shown that existence of negative differential capacity depends on charge state of Si nanoclusters or electron traps in the insulating matrix. In case of SixOyNz films the tw…
Objective: The objective of the present study was to enhance the solubility and dissolution rate of Aripiprazole (APZ), a water insoluble drug, by a solid dispersion technique. Methods: Solid dispersions (SD) of APZ were prepared by fusion method using water-soluble carriers like, polyethylene glycol 4000 (PEG 4000),…
