201 Rees, Don M.The termite problem in UtahTermites or " white ants" are present in all parts of Salt Lake City and are generally found in other cities and towns throughout the state. Three different species of termites have been found in Utah: Reticulitermes tibialis Banks, Reticuliterm.es tumiceps Banks, and Kalotervies minor Hagen. Reticu...1939-12-27
202 Goodwin, Charles CarrollThat briefReply to A. M. Gibson's pamphlet entitled, "Brief in re Senate bill number 10."Latter Day Saints; Polygamy1886-04-12
203 Mattis, Daniel C.Theory of electronic switching effect as a cooperative phenomenonA modified form of Zener tunneling theory, in which we assume that the tunneling barrier is a decreasing collective function of electronic excitation, is shown to imply insulator- to-metal switching characteristics similar to those reported by Ovshinsky for glass film devices. In addition, our І-V ...Electronic switching; Negative resistance1969-05
204 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
205 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
206 Mattis, Daniel C.Theory of negative-mass cyclotron resonanceIn recent communications1'2 Dousmanis et al. suggest that the re-entrant energy contours of the heavy-hole bands in Ge and Si3 could contribute a negative resistivity component to the overall resistivity of these materials, possibly related to a nonequilibrium density of carriers in these re-ent...Cyclotron resonance; Steady state1959-07
207 Mattis, Daniel C.Theory of paramagnetic impurities in semiconductorsIn this paper, a model of a paramagnetic impurity in a semiconductor (or of an F' center in an alkali halide) is proposed. It is an exactly soluble form of the quantum-mechanical 3-body problem. Specifically, we deal with 2 interacting particles in any number of dimensions in an attractive external ...Paramagnetic impurities; Eigenstates1966
208 Mattis, Daniel C.Theory of the anomalous skin effect in normal and superconducting metalsChambers' expression for the current density in a normal metal in which the electric field varies over a mean free path is derived from a quantum approach in which use is made of the density matrix in the presence of scattering centers but in the absence of the field. An approximate expression use...Skin effect1958-07
209 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

211 Gesteland, Raymond F.Translation of Rl7 RNA fragmentsExamination of the events during infection of cells by RNA phages reveals phemonomena that are surprisingly complex for a virus that has only enough information to code for three to four proteins. The coat protein is synthesized at a rapid rate through most of the infectious cycle making it the pre...Electrophoresis; RNA, Messenger; Peptide Biosynthesis; Kinetics1969
212 Firmage, Edwin B.Treaty on the nonproliferation of nuclear weaponsTHE NEED : On March 13, 1969, the United States Senate by a vote of 83 to 15 consented to the ratification of a treaty described as "the most important international agreement brought before the U. S. Senate since the North Atlantic Pact" and "the most important international agreement limiting nucl...Arms control; Diffusion of arms; Atomic negotiations1969-10
213 Chamberlin, Ralph V.Two genera of trap-door spders from CaliforniaWhile trap-door spiders have long excited general interest, as a group they are very imperfectly known. This is due largely to the fact that their subterranean habits enable them to escape ordinary observation and to have, as a consequence, relatively poor representation in collections, both as to s...1937-08-18
214 Durrant, Stephen D.Two new gophers from UtahA study of mammals in the collection of the University of Utah, taken in western Utah during the summer of 1936 has brought out some interesting differences in the genus Thomomys. Series of gophers from Wah Wah Springs, Beaver County, and from Oak Creek Canyon, Millard County, differ sufficiently fr...1937-08-18
215 Jones, David T.Two protozoans from Great Salt LakeThe amoeba inhabiting the waters of Great Salt Lake, which has been previously referred to Amoeba Umax (Dujard in) . Named for mv colleague at the University of Utah, Dr. Seville Flowers. Type localtiv, Garfield Beach, Great Salt Lake, Utah. Type figures 1 to 3. Small amoebae, 18 to 40 micra in diam...1944-11-15
216 Chamberlin, Ralph VaryUniversity of Utah: a history of its first hundred years, 1850-1950The need of a general history of the University of Utah has been long apparent. The need became more frequently voiced as the men who knew the University of old at first hand and had played important roles in its development passed away leaving it ever more difficult to obtain a clear picture of ma...University of Deseret1960
217 Garrett, A. O.The uredinales or rusts of UtahThe catalogue of the rusts of Utah presented herewith is the result o f thirty-four years work in collecting and observation by the author. During this time the writer has collected in every county in the state, excepting Daggett.1937-11-18

221 Miller, Joel StevenUsing fissionAtoms are just like people, both are lazy. Energy is a measure of work, i.e., more work implies more energy. Atoms do not like to work, hence they try to reduce the energy in their atomic system. For different elements the energy reduction occurs by reaction, e.g., an energetic sodium atom reacts w...Uranium-235; Uranium-2381966
222 Garrett, A. O.The ustilaginales or smuts of UtahSince September, 1902, the writer has been collecting fungi in Utah. During that time collecting has been carried on in every county in Utah. Several consecutive summers were spent at Brighton, in Big Cottonwood Canyon, Salt Lake County. The summer o f 1911 was spent with the late Dr. Rydberg, colle...1939-05-15
223 Chamberlin, Ralph V.The vachoniidae - A new family of false scorpions two new species from Caves in Yucatanexistence of a well-defined and previously unrecognized family of the false scorpions belonging to the superfamily Neobisioidea. The family characteristics are well marked, the most distinctive being the venom apparatus of the chela, which is functionally developed in the movable finger only. A vest...1947-08-26
