Chromium carbide – nickel chromium powder Cr3C2-25wt.NiCr was plasma sprayed by a water-stabilized system WSP®. A series of experiments with variable feeding distance was carried out. Basic characterization of coatings was done by XRD, SEM and light microscopy plus image analysis. Microhardness was measured on polished cross sections. The main focus of investigation was on resistances against w...

The word “Layers” refers to the deferent layers within a communications system—such as an organization’s or person’s website—that together make communication possible. The idea of “Layers” is attributed to Yochai Benkler, Professor of Law at New York University, who first used it to describe a communications system that is divided in three distinct layers: 1. The “physical” layer across which c...

We study low frequency waves that propagate in a region of layered semi-convection. Layered semi-convection is predicted to be present in stellar and planetary interiors and can significantly modify the rate of thermal and compositional mixing. We derive a series of analytical dispersion relations for plane-parallel layered semi-convection in the Boussinesq approximation using a matrix transfer...

A benchmark contamination rate for prefilled syringe compounding was determined by using a medium-fill-simulation method. One thousand thirty-five 1-mL tuberculin syringes were aseptically filled with 0.9 mL of sterile soybean-casein digest medium and capped. These syringes were placed into clear nonsterile plastic bags and incubated at 35 degrees C for seven days, then inspected for cloudiness...

We studied the properties of electromagnetic waves that were emitted from a source placed inside a left-handed medium based on a two-dimensional labyrinth. While the arguments of geometrical optics suggest that the field emitted from the source would be focused outside the left-handed medium no matter where the source was placed, our results proved the contrary. We found that the field emitted ...

18 Objectives: To monitor the stability of rifampicin (RIF) in Löwenstein-Jensen medium (L-J 19 medium) and 7H9 broth, which are the commonly used media for drug susceptibility testing (DST) 20 for Mycobacterium tuberculosis. Methods: Rifampicin degradation in stock solution, 7H9 broth, 21 L-J medium, and during the inspissation process for L-J medium preparation was serially 22 monitored by hi...

We present our updated results of the nucleon-nucleon potential in quenched lattice QCD simulations with the plaquette gauge action and the Wilson quark action on the 324(≃ (4.4fm)4) lattice. From the equal-time Bethe-Salpeter (BS) wave function, the NN potential is constructed through the Schrödinger-type equation. Resulting NN potential has all the qualitative features which phenomenological ...

Abstract Background The data on medium-term follow-up of coronavirus disease-19 (COVID-19) pneumonia survivors is scarce. Medium-term will generate knowledge and help in devising a structured plan to facilitate enrolment clinical trials assessing the role antifibrotic drugs modifying course disease order avert long-term pulmonary sequelae disease. study was aimed evaluate lung findings (3 month...
