Higher dimensional cylindrical or Kasner type electrovacuum solutions
(Springer/Plenum Publishers, 2013)
We consider a dimensional Kasner type diagonal spacetime where metric functions depend only on a single coordinate and electromagnetic field shares the symmetries of spacetime. These solutions can describe static cylindrical ...
The Saricicek howardite fall in Turkey: Source crater of HED meteorites on Vesta and impact risk of Vestoids
(Wiley, 2019)
The Saricicek howardite meteorite shower consisting of 343 documented stones occurred on September 2, 2015 in Turkey and is the first documented howardite fall. Cosmogenic isotopes show that Saricicek experienced a complex ...
Symmetry of Brans-Dicke gravity as a novel solution-generating technique
(Amer Physical Soc, 2018)
A symmetry of Brans-Dicke gravity in (electro) vacuo or in the presence of conformally invariant matter is presented and used as a solution-generating technique starting from a known solution as a seed. This novel technique ...
Perfect fluid solutions of Brans-Dicke and f (R) cosmology
(Academic Press Inc Elsevier Science, 2018)
Brans-Dicke cosmology with an (inverse) power-law potential is revisited in the light of modern quintessence and inflation models. A simple ansatz relating scale factor and scalar field recovers most of the known solutions ...
An Improved Method for Determination of Refractive Index of Dielectric Films from Reflectance Spectrum by Using the Generalized Morse Wavelet
(Sciendo, 2021)
The Generalized Morse Wavelet (GMW) algorithm was adapted to determine the refractive index of dielectric film from the reflectance spectrum. A theoretically generated reflectance spectrum in the range of 300-1200 nm ...
9-(4-Nitrophenylsulfonyl)-9H-carbazole
(Wiley-Blackwell, 2011)
In the title molecule, C18H12N2O4S, the carbazole skeleton is nearly planar [maximum deviation = 0.037 (1) A] and is oriented at a dihedral angle of 73.73 (5)degrees with respect to the benzene ring. An intramolecular ...
5-(3,6-Dibromo-9H-carbazol-9-yl)pentanenitrile
(Wiley-Blackwell, 2011)
In the title compound, C17H14Br2N2, the carbazole skeleton is nearly planar [maximum deviation = 0.055 (2) angstrom]. In the crystal, aromatic pi-pi stacking is observed between parallel carbazole ring systems of adjacent ...
Stationary axially symmetric solutions in Brans-Dicke theory
(Amer Physical Soc, 2015)
Stationary, axially symmetric Brans-Dicke-Maxwell solutions are reexamined in the framework of the Brans-Dicke (BD) theory. We see that, employing a particular parametrization of the standard axially symmetric metric ...
Brans-Dicke-Maxwell solutions for higher dimensional static cylindrical symmetric spacetime
(Amer Inst Physics, 2015)
In this paper, Brans-Dicke-Maxwell type vacuum solutions are considered for a static cylindrically symmetric spacetime in arbitrary dimensions. Exact solutions are obtained by directly solving the field equations for the ...
Novel 3-D spacer all fibre piezoelectric textiles for energy harvesting applications
(Royal Soc Chemistry, 2014)
The piezoelectric effect in poly(vinylidene fluoride), PVDF, was discovered over four decades ago and since then, significant work has been carried out aiming at the production of high beta-phase fibres and their integration ...
