Edmunds, George F. Jr. | An annotated key to the nymphs of the families and subfamilies of mayflies | Attempts to provide keys to the families and subfamilies of Ephemeroptera nymphs in general entomology textbooks (i.e. Essig (1942), Chu (1949), and Brues, Melander and Carpenter (1954)) have been far from satisfactory. This difficulty exists largely because of the failure of specialists of the Ephe... | 1963-06 | |

Mattis, Daniel C. | Thermal screening effects in a ferromagnet | In considering the theory of spin waves,1 we have examined elementary excitations of the Hamiltonian and lowest-order interactions among these excitations, in cases when j(Rij) is a very long-ranged, oscillatory interaction.2 As numerical computation is required, we are preparing to program the I... | Ferromagnet; Thermal screening | 1963-06 |
