Significant heat was generated for about 740 min when a sample of palladium foil was electrolyzed as the cathode in D2O+LiOD. A very stable Seebeck calorimeter is described and used to make the measurements. The source of this anomalous energy is unknown. However, the observed energy and production of unexpected elements based on EDX examination are similar to the behaviors claimed by many peop...

Innovative CMC-based hydrogels with great potentials for usage in medical area were principally synthesized as per two strategies .The first involved reaction of epichlorohydrin in alkaline medium containing silver nitrate to yield silver nano-particles (AgNPs)-loaded CMC hydrogel. While CMC acted as stabilizing for AgNPs, trisodium citrate was added to the reaction medium to assist CMC in esta...

Introduction: Here we present an analysis of sulphate minerals from the Triassic coastline of the South West UK, utilising an Energy Dispersive X-Ray Diffraction (ED-XRD) instrument in a novel backreflection geometry that enables analysis of unprepared rock samples. Sulphate minerals are of particular interest in planetary science as they are a product of an aqueous altered environment. This st...

We consider the linearization of the three-dimensional water waves equation with surface tension about a flat interface. Using oscillatory integral methods, we prove that solutions of this equation demonstrate dispersive decay at the somewhat surprising rate of t−5/6. This rate is due to competition between surface tension and gravitation at O(1) wave numbers and is connected to the fact that, ...

This paper introducesminiPixD: a new, compact system that utilises transmission X-ray imaging and X-ray diffraction (XRD) to locate and identify materials of interest within an otherwise opaque volume. The system and the embodied techniques have utility in security screening, medical diagnostics, non-destructive testing (NDT) and quality assurance (QA). This paper outlines the design of the sys...

We establish a low Mach number limit for classical solutions over the whole space of a compressible fluid dynamic system that includes dispersive corrections to the Navier-Stokes equations. The limiting system is a ghost effect system [26]. Our analysis builds upon the framework developed by Métivier and Schochet [20] and Alazard [2] for non-dispersive systems. The strategy involves establishin...

In this paper the Semi-Analytical Finite Element (SAFE) method for modeling guided wave propagation is extended to account for linear viscoelastic material damping. Linear viscoelasticity is introduced by allowing for complex stiffness constitutive matrices for the material. Dispersive characteristics of viscoelastic waveguides, such as phase velocity, attenuation, energy velocity and cross-sec...

We use the master equation approach to calculate the energy level shifts of an atom in the presence of a general dielectric semi-infinite medium characterized by a dielectric constant ǫ(ω). Particularly, we analyze the case of a non-dispersive medium for which we obtain a general expression for the interaction as well as the asymptotic behaviors for k0z ≪ 1 (non-retarded regime) and k0z ≫ 1 (re...

Beginning in 2017, most physicians who participate in Medicare are subject to the Medicare Access and CHIP Reauthorization Act (MACRA), the milestone legislation that signals the US health care system's transition from volume-based to value-based care. Here we review emerging trends in development of value-based healthcare systems in the US. MACRA and the resulting Quality Payment Program creat...
