151 Behle, William H.The birds of Southeastern UtahSoutheastern Utah is a rugged and colorful portion of the state. As a part of the Colorado Plateau Physiographic Province it is characterized by an arid climate, multicolored but mostly red sandstones, shales and limestones, weathered sand deep box canyons, and high, isolated, lacolithic mountain ra...1960-10
152 Warner, Homer R.Medical Diagnosis Using a Digital Computer and Analog Computer Technics in Study of Control Mechanisms in the Circulatory SystemBiomedical Informatics1961
153 Mattis, Daniel C.Exact wave functions in superconductivityThe ground-state wave function and some of the excited states of the BCS reduced Hamiltonian are found. In the limit of large volume, the boundary and continuity conditions on the exact wave function lead directly to the equations which Bardeen, Cooper, and Schrieffer found by a variational techniqu...Ground states1961

156 Gardner, Reed M.Analog Computer Simulation of Heart ResponseBiomedical Informatics1961
157 Flowers, SevilleThe hepaticae of UtahThe 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
158 Nielsen, Lewis T.An identification guide to the mosquitoes of UtahThe 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

In this bulletin Rees reported the occurrence in the state of 31 species, representing 4 genera, and discussed their biology, distribution, life history and importance. Subsequent publications by Rees (1944), Rees ...1961-06
160 Jenike, A.W.Gravity flow of bulk solidsThere 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
161 Warner, Homer R.Analysis of the Role of Indicator Technics in Quantitation of Valvular RegurgitationBiomedical Informatics1962
162 Warner, Homer R.Use of Analogue Computers in the Study of Control Mechanisms in the CirculationBiomedical Informatics1962
163 Mattis, Daniel C.Ordering energy levels of interacting spin systemsThe 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 arrays1962
164 Firmage, Edwin B.Ernst Freund: pioneer of administrative lawErnst 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; Biography1962
165 Mattis, Daniel C.Theory of ferromagnetism and the ordering of electronic energy levelsConsider 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
166 Johanson, Jerry Ray; Jenike, A.W.Stress and velocity fields in gravity flow of bulk solidsThis 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
167 Mattis, Daniel C.Role of Fermi surface and crystal structure in theory of magnetic metalsWe 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 structure1962-11

169 Mattis, Daniel C.Theory of magnetothermomechanicsWe 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; Magnetostriction1963-01
170 Mattis, Daniel C.Ground state of interacting spinsThe 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 interaction1963-04
171 Mattis, Daniel C.Thermal screening effects in a ferromagnetIn 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 screening1963-06
172 Edmunds, George F. Jr.An annotated key to the nymphs of the families and subfamilies of mayfliesAttempts 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
173 Mattis, Daniel C.Ferromagnetism and spin waves in the band theoryIntra-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 rule1963-12
