Interactions between halide ions (fluoride and iodide) and t-butyl alcohol (TBA) dissolved in water are probed using a recently developed hydration-shell spectroscopic technique and theoretical cluster and liquid calculations. High ignal-to-noise Raman spectroscopic measurements are combined with multivariate curve resolution (Raman-MCR) to reveal that while there is little interaction between ...

Abstract A high-quality earphone with multiple sound-generating units and frequency-dividing circuits, a core of consisting balanced armature units, aided by analog circuits an shell made light-cured resin, is designed. The whole project physical production realized. analysis results the frequency response curve, which are obtained help tester, show that headphones in sensitivity, curve stabili...

We perform first-principles path integral Monte Carlo (PIMC) and density functional theory molecular dynamics (DFT-MD) calculations to explore warm dense matter states of LiF. Our simulations cover a wide density-temperature range of 2.08-15.70gcm^{-3} and 10^{4}-10^{9} K. Since PIMC and DFT-MD accurately treat effects of atomic shell structure, we find a pronounced compression maximum and a sh...

UNLABELLED : The Lyon Brace, or adjustable multi-shell brace, has been used for more than 60 years.The use and function of the Lyon Brace includes:- The utilization of one or two corrective plaster casts, which enables a true lengthening of the concave ligaments.- An oriented CAD-CAM moulding in 3D auto correction after the removal of the plaster cast.- A blueprint adapted to Lenke's classifica...

We report on the discovery of thermal and non-thermal X-rays from the shells of the super bubble (SB) 30 Dor C in the Large Magellanic Cloud (LMC). The X-ray morphology is a nearly circular shell with a radius of ∼40 pc, which is bright on the northern and western sides. The spectra of the shells are different from region to region. The southern shell shows clear emission lines, and is well fit...

We present high resolution Chandra observations of the remnant of SN1987A in the Large Magellanic Cloud. The high angular resolution of the Chandra X-ray Observatory (CXO) permits us to resolve the X-ray remnant. We find that the remnant is shell-like in morphology, with X-ray peaks associated with some of the optical hot spots seen in HST images. The X-ray light curve has departed from the lin...

2014 A model interaction is used which is determined by a given nuclear matter saturation curve. This interaction is used in a Hartree-Fock calculation of 40Ca to study the density, the single particle energies and the shell-model potential for various compressibility coefficients derived from the nuclear matter saturation curves.

Based on the model of nuclear shells, a computer spatial structure atomic nucleus was constructed. The application new approach, by analogy with modeling atom electron shell, allowed us to visualize nucleus. In presented model, concept nucleon is also extended include, besides protons and neutrons, deuterons in shell. nature quantum magic numbers clarified, shell shown. resulting arrangement nu...

Let {uk} be a Lucas sequence. A standard technique for determining the perfect powers in the sequence {uk} combines bounds coming from linear forms in logarithms with local information obtained via Frey curves and modularity. The key to this approach is the fact that the equation uk = xn can be translated into a ternary equation of the form ay2 = bx2n + c (with a, b, c ∈ Z) for which Frey curve...

We present simple and predictive scenarios for neutrino masses which lead to a bimaximal pattern of mixings that apparently provides the best fit to the current solar and atmospheric neutrino data. It is shown that an approximate global Le −Lμ −Lτ symmetry, broken only by Planck scale effects, can naturally explain the bimaximal mixing pattern. In one scenario, the solar neutrino oscillation pa...
