On Her Own Terms: Annie Montague Alexander and the Rise of Science in the American West

At a time whilst girls couldn't vote and extremely few have been interested in the realm outdoors the house, Annie Montague Alexander (1867-1950) used to be an intrepid explorer, novice naturalist, expert markswoman, philanthropist, farmer, and founder and customer of 2 usual historical past museums on the college of California, Berkeley.

The publication could be considered as an advent to time-hadronic waves in dissipative our bodies, particularly viscoelastic solids and fluids. The inhomogeneity of the waves, that's given that planes of continuing part will not be parallel to planes of continuing amplitude, is proven to be strictly on the topic of the dissipativity of the medium.

Example text

For large values of p both the electric field and the horizontal component of the magnetic field decrease as 1jr 4 . 61) The function Z is called the impedance of a plane wave descending normally to the earth's surface. This feature of the behavior of the electromagnetic field is the reason this range of parameters p is called the wave zone. Usually this name indicates the propagation of electromagnetic waves into the earth. In spite of the fact that in the quasistationary approximation this phenomenon is not considered, this term is still used because it correctly describes the path of propagation of the field.

Suppose that the separation r is greater than the thickness HI of the first layer. Then, the coincidence of functions In B, and Q E, ' observed on the surface of a two-layered medium, with corresponding components for a uniform half space with conductivity "Yz, occurs when the parameter r /0 is small in both media. If the separation is less than the thickness of the upper layer, the same coincidence is observed, providing that the parameter HI/o is small in both media. It is proper to note that this behavior of In B, and Q E, takes place regardless of the ratio of conductivities.

141) For example, the series for the quadrature component of the magnetic field always starts with a term proportional to w, while the corresponding leading term of the series representing the in-phase component of the electric field is proportional to w Z• As was shown in the previous section, this behavior occurs when interaction between induced currents can be neglected. From Eqs. 136) it follows that the second term in the series for the quadrature component of the magnetic field, along with the leading term of the series for the in-phase component of the secondary field, are different for B; and B r • They contain either a fractional power of w or t'nw.
