This paper describes a method for determining the dielectric constant of a biological tissue. A suitable way to make a dielectric measurement that is nondestructive and noninvasive for the biological substance and broadband at the frequency range of the network analyzer is to use a reflection method on an open ended coaxial line. A coaxial probe in the frequency range of the network analyzer from 17 MHz to 2 GHz is under investigation and also a calibration technique and the behavior of discrete elements in an equivalent circuit of an open ended coaxial line. Information about the magnitude and phase of the reflection coefficient on the interface between a biological tissue sample and a measurement probe is modeled with the aid of an electromagnetic field simulator. The numerical modeling is compared with real measurements, and a comparison is presented.

How the Virgin Mary, a symbol of chastity and a lofty figure, conceived Jesus Christ has been a mystery since the beginning of the Christian era and will remain so. Just as we do not have a biological tissue sample belonging to Jesus Christ to subject to tests, we do not have any biological material which might identify the Virgin Mary as a mosaic, chimera or hermaphrodite. Although current scientific knowledge offers us the possibility that this pregnancy was an example of parthenogenesis (activation of an unfertilized female gamete to form a new individual animal or plant), the presence of the Y chromosome in Jesus complicates the matter. Thus, the present review aims to present data which to explain scientific alternatives as to how the Virgin Mary might have conceived Jesus Christ. We believe that the answer to this scientific problem may be of benefit in the treatment of infertile patients wishing to become pregnant.
