177 | Flowers, Seville | The hepaticae of Utah | The Hepaticae, or liverworts, are small green plants mostly growing in damp or wet places, although a considerable number of them inhabit dry shady places, even in desert regions. As a whole, they are inconspicuous and, together with the mosses, lichens and other primitive forms of plant life, occup... | 1961-05-30 | ||

178 | Nielsen, Lewis T. | An identification guide to the mosquitoes of Utah | The first detailed report on the mosquito fauna of Utah was published by pees (1943). In this bulletin Rees reported the occurrence in the state of 31 s p e c ie s , representing 4 genera, and discussed their biology, distribution, life history and importance. Subsequent publications by Rees (1944),... | 1961-06 | ||

180 | Jenike, A.W. | Gravity flow of bulk solids | There is hardly an industry in existence which does not use solid materials in bulk form. Where the volume of the solids is substantial, gravity is usually relied upon to cause the solids to flow. Such materials as ores, coal, cement, flour, cocoa, soil, to which the general term of bulk solids is a... | 1961-10 | ||

182 | Firmage, Edwin B. | Ernst Freund: pioneer of administrative law | Ernst Freund was born in New York City on January 30, 1864, during a visit of his family to the United States from their native Germany. Much of his education took place in Germany, a fact that significantly influenced his views on administrative law. He studied successively at Dresden, Frankfort, B... | Memoriam; Biography | 1962 | |

183 | Mattis, Daniel C. | Ordering energy levels of interacting spin systems | The total spin S is a good quantum number in problems of interacting spins. We have shown that for rather general antiferromagnetic or ferrimagnetic Hamiltonians, which need not exhibit translational invariance, the lowest energy eigenvalue for each value of S [denoted E(S) ] is ordered in a natural... | Interacting spin; Energy levels; Ferrimagnetic arrays | 1962 | |

185 | Mattis, Daniel C. | Theory of ferromagnetism and the ordering of electronic energy levels | Consider a system of N electrons in one dimension subject to an arbitrary symmetric potential, V(xi,…,xN), and let E(S) be the lowest energy belonging to the total spin value S. We have proved the following theorem: E(S) | 1962-01 | ||

186 | Johanson, Jerry Ray; Jenike, A.W. | Stress and velocity fields in gravity flow of bulk solids | This paper is an extract from a Ph.D. thesis written by Johanson in the Department of Mechanical Engineering, College of Engineering, University of Utah; it follows earlier publications by Jenike [e.g. 1,5]. The purpose of the work has been to develop a mathematical theory of flow of bulk solids. Th... | 1962-05 | ||

187 | Mattis, Daniel C. | Role of Fermi surface and crystal structure in theory of magnetic metals | We have investigated the magnetic ground state of metals using an idealized theory of magnetism based on the Ruderman-Kittel-Yosida indirect exchange interaction. The preliminary, but suggestive, results reported here are for simple cubic structures and spherical Fermi surface. We find that as the... | Magnetic metals; Crystal structure | 1962-11 | |

189 | Mattis, Daniel C. | Theory of magnetothermomechanics | We show that in both ferromagnetic and antiferromagnetic systems with weak magnetostrictive coupling the coefficient of thermal expansion gives a useful measure of the magnetic specific heat. We also analyze the strong coupling situation by means of our simplified, but soluble model, and find it pos... | Magnetothermomechanics; Magnetostriction | 1963-01 | |

190 | Mattis, Daniel C. | Ground state of interacting spins | The question is posed of how the ground state of the Heisenberg Hamiltonian H= - ΣFij Si-Sj depends on the magnitude s of N interacting spins, particularly in the case of long-ranged oscillatory interactions Fij. It is discussed whether fixing the geometry and the bond strengths Fij suffices to d... | Ground states; Interacting spin; Ruderman-Kittel interaction | 1963-04 | |

191 | 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 | |

192 | 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 | ||

193 | Mattis, Daniel C. | Ferromagnetism and spin waves in the band theory | Intra-atomic exchange (Hund's rule mechanism) and Heisenberg nearest-neighbor exchange are examined for their role in the ferromagnetism of metals with degenerate bands. We examine the ground state, and find there is ferromagnetism once the largest eigenvalue j00 of the exchange matrix exceeds 1/2... | Band theory; Hund's rule | 1963-12 | |

200 | Morrow, Carolyn | Baudelaire as seen through Les Fleurs du Mal | Modern phychology emphasizes the similarity of the dream to works of art, especially poetry. The dreamer or the poet works through symbols, which express his inner self, a self largely unknown to the conscious mind.1 There can be no "difference irreductible entre le 'moi' subjectif and le 'je' crea... | 1964 |
