A numerical parametric study is presented of a domestic thermal storage heat exchanger to explore the effect highly localized positive temperature coefficient cylindrical heating elements in phase change material (PCM) with conductive enhancement by open-pore metal foam. By using 90 L commercially available Rubitherm RT70HC wax, 5.7 kWh energy captured unit. The discharge via central convective...
Measurement of nonhomogeneous special nuclear material using passive gamma techniques is difficult because it is not practical to develop standards with the characteristics of the samples. Each sample is different. And the samples must be measured nondestructively. Modeling methods must be used. The modeling methods assume homogenous distribution of radioactive and matrix material within the co...
The diffraction of electromagnetic plane waves by a rectangular grating formed by discrete steps in the interface of a homogeneous, isotropic, linear, negative phase-velocity (negative index) material with free space is studied using the semi-analytic C method. When a nonspecular diffracted order is of the propagating type, coupling to that order is significantly larger for a negative index mat...
Batisite was reported to be a nonlinear optical material showing second harmonic generation. Using dielectric spectroscopy and polarization measurements, we provide a thorough investigation of the dielectric and charge-transport properties of this material. Batisite shows the typical characteristics of a linear lossy dielectric. No evidence for ferro- or antiferroelectric polarization is found....
The diffraction of electromagnetic plane waves by a rectangular grating formed by discrete steps in the interface of a homogeneous, isotropic, linear, negative phase– velocity (negative index) material with free space is studied using the semi–analytic C method. When a nonspecular diffracted order is of the propagating type, coupling to that order is significantly larger for a negative index ma...
currently, localized pulpalgia is listed as a rare manifestation of chemotherapy treatments in patients with malignant tumors. the neuropathy originated from neurotoxicity of anticancer drugs is usually described as a diffuse jaw pain or numbness in orofacial structures. this article reports localized tooth pain as a possible outcome of administrating high dosage chemotherapy drugs particularl...
Using the newly developed VASP2WANNIER90 interface we have constructed maximally localized Wannier functions (MLWFs) for the e(g) states of the prototypical Jahn-Teller magnetic perovskite LaMnO(3) at different levels of approximation for the exchange-correlation kernel. These include conventional density functional theory (DFT) with and without the additional on-site Hubbard U term, hybrid DFT...
The type of Scleroderma stellatum from Brazil exhibits a sharp echinulate, dark brown peridium, and the type of S. bermudense from Bermuda has a peridium that is loosely woven and fibrillose, whitish to pale brownish. These characters indicate two independent species. This information is contrary to that of Guzmán in 1970, who interpreted S. bermudense to be a synonym of S. stellatum based on t...
