The dispersion relations for conventional uniaxial dielectric mediums may be characterized as elliptical or elliptical–like, according to whether the medium is nondissipative or dissipative, respectively. However, under certain constitutive parameter regimes, the dispersion relations may be hyperbolic or hyperbolic–like. We investigate planewave propagation in a hyperbolic/hyperbolic–like uniax...

Communication is an integral part of everyday life. Consumers chat with friends, search for information, and complain to customer service. Salespeople pitch products, employees answer questions, market researchers ask them. But communication doesn’t occur in a vacuum. Modalities (e.g., speaking or writing), channels text, phone call, email), devices smartphone computer) are the mediums through ...

Seed mediated aqueous chemical growth (ACG) route was used for the growth of ZnO nanostructures on Si substrate in four different growth mediums. The growth medium has shown to affect the morphology and the size of the different nanostructures. We observed that the medium containing zinc nitrate anions yields the nanorods, in a medium containing zinc acetate anions nano-candles are obtained. Wh...

The importance of accurate, reliable recording mediums cannot be understated. Function and esthetics are directly related to this critical step. Dental recording materials must be accurate, easily manipulated, and economical for effective use. Five types of intraoral records of 31 patients were registered and placed on an arcon, semiadjustable articulator to measure the magnitude and direction ...

A light ray, incident at about 5 degrees to the normal, is geometrically plotted through the drawing of the cross section of a soybean leaf using Fresnel's equations and Snell's law. The optical mediums of the leaf considered for ray tracing are air, cell sap, chloroplast, and cell wall. The above ray is also drawn through the same leaf cross section considering cell wall and air as the only op...

We consider waves travelling in two different mediums each endowed with a constant speed of propagation. At the interface between mediums, refraction rays optic geometry obeys Snell’s law. provide sufficient conditions on geometry’ and propagation for exact boundary controllability.

Spiritism is a French offshoot of the spiritualistic movement that developed in the 19th century. In Brazil it is the fourth largest religion and its practices are deeply connected to mediumistic activity. This is not reimbursed but considered charitable voluntary work [8]. We examined the socio-demographic profile, social adjustment and mental health in Spiritist mediums as well as the clinica...

Korean entertainment industries are dominating all over the world, including in Philippines. These celebrated mediums included movies, songs, and products, many of which beloved by Filipinos. As such, this study aims to determine factors that affect buying decisions Filipinos with products services an extended theory planned behavior (TPB) approach. A total 306 Filipino survey participants were...

Non–dissipative mediums with both simultaneously negative permittivity and permeability were first investigated by Veselago [1] in 1968. These mediums support electromagnetic wave propagation in which the phase velocity is antiparallel to the direction of energy flow, and other unusual electromagnetic effects such as the reversal of the Doppler effect and Cerenkov radiation. After the publicati...
