The LIGO and the Virgo collaborations have recently announced the first detections of Gravitational Waves.Due to their weak amplitude, Gravitational Waves are expected to produce a very small effect on free-falling masses, which undergo a displacement of the order of 10-18 m for a Km-scale mutual distance.This discovery showed that interferometric
In this paper possibility of creating a medium based on graphene-dielectric structures with the hyperbolic shape wave number dispersion is considered for the case when two types of graphene sheets with different chemical potentials periodically alternate.Using the Bloch theorem and the transfer matrix method, dispersion relations for the light wave
Background: Nodular glomerulosclerosis deus gorras is a characteristic histological finding of diabetic nephropathy (DN) with thickened glomerular basement membrane (GBM) and hyalinized arterioles.Idiopathic nodular glomerulosclerosis (ING), a rare distinct clinicopathologic entity, is the term used to denote classic DN confirmed by light microscop
The development of sustainable building materials with reduced environmental footprint in both, manufacturing and operational phases of the material lifecycle, is attracting increased interest in the construction industry worldwide.A recent innovation, the geopolymer foam concrete, combines the performance benefits and operational energy savings ac
