A homogeneous series of monthly means of terrestrial-magnetic activity for the years 1872 to 1930 is derived and extended backward, in annual means, to 1835. The annual variation of magnetic activity and of the relative sunspot-numbers is discussed by...

Expressions for the self and mutual impedances within a radiating system are developed by the use of the generalized reciprocity theorem. These expressions are given in terms of the distributions of the electric field intensities along the radiators....

Cardiac standstill, regardless of the sequential development of the etiologic factors responsible for its occurrence, constitutes a clinical problem of no little magnitude so far as a favorable outcome in any individual case is predicated on the initiation...
A system for recording the direction of arrival and intensity of static on short waves is described. The system consists of a rotating directional antenna array, a double detection receiver and an energy operated automatic recorder. The operation of the...

Alloway published this article shortly after he joined Avery's lab. In it, Alloway demonstrated that by dissolving certain living pneumococci cells in sodium dexoycholate one could bring about transformation in vitro, rather than in laboratory mice...
For several years, it has been well known that, in the natural vibration of a piezoelectric oscillating crystal, there is a certain period proportional only to the thickness, but, so far as we are aware, there has been no concrete explanation for this...
