Abstract Mold slag entrainment during the continuous casting process presents a late stage source of non-metallic inclusions (NMI) with high likelihood ending up in final product. The reaction between entrained phase and surrounding liquid steel mold affects inclusion morphology properties. However, there is lack information on kinetics NMI-steel reaction. A novel approach, utilizing controlled...

A rapid and simple technique has been developed for inspection of defects of steel using laser induced breakdown spectroscopy (LIBS). Irradiation from a Q-switched Nd:YAG laser was focused onto the sample surface by a plano-convex lens with a spot diameter of about 1mm to ablate a portion of sample and generate a micro plasma. Emission from the plasma was transmitted by a fiber optics to a Pasc...

The tremendous potential for the manifold applications of porphyrins, porphyrazines, and phthalocyanines derives from their photophysical and electrochemical properties, their remarkable stability, and their predictable and rigid structure. These applications include nonlinear optics, catalysts, sensors, actuators, molecular sieves, and therapeutics. All of these properties are modulated by app...

This study describes a new tanks-in-series model for analyzing non-ideal flow regimes in single-strand tundish. The tundish was divided into two interconnected tanks, namely an inlet tank and outlet tank. A water experiment carried out to separately measure the residence-time distribution (RTD) of tanks. Drift beads were adopted simulate non-metallic inclusions molten steel. Dead volume fractio...

Disorder of the gastrointestinal tract of the dairy cattle is common due to indiscriminate feeding behavior. An ingested foreign body by cattle is divided in to two main groups. The first category is foreign bodies of nonmetallic origin and the second category is metallic origin. Entrance and migration of foreign bodies through the body tissue leads to many complications that differ according t...

The characteristics of dielectric backed planar conducting layers of arbitrarily shaped in a rectangular waveguide are calculated by means of coupled integral equation technique (CIET) which accurately takes higher order mode interactions. Equivalent structures for the accurate analysis whole structure are introduced in which magnetic surface currents are identified as the unknowns at the apert...

The most common clinical causes of metallic foreign body in the breast are surgical clips, pieces of guide-wire and gunshot wounds. Metallic foreign bodies can lead to local breast pain, abscesses, pneumothorax after granulomas or migration, and cardiac tamponade. Mammotome biopsy, fluoroscopy, guide-wire biopsy and radio-guided occult lesion localization (ROLL) are the standard techniques appl...

The electronic behavior of metallic carbon nanotubes under the influence of externally applied electric fields is investigated using the Non-Equilibrium Green’s function method self consistently coupled with three-dimensional (3D) electrostatics. A nearest neighbor tight binding model based on a single pz orbital for constructing the device Hamiltonian is used. The 3D Poisson equation is solved...

DIELECTRIC LEAKY-WAVE ANTENNA ANALYSIS OF ARBITRARY METALLIC SHAPE In this article, the resolution of a dielectric leaky-wave antenna problem of arbitrary metallic strips is presented. This is suggested with an aim of highlighting the influence of the form of the metallic parts, and their transverse surface on the radiating characteristics and to compare the advantages and disadvantages of the ...
