351 DeTar, CarletonO(2,1) decomposition of the equal-mass multipheripheral equation at t=0We extend the results of a group-theoretical analysis of the t=0 multiperipheral equation to the case t<0 for pairwise equal masses. Using variables discussed in a previous paper, we diagonalize the equation in the Bali-Chew-Pignotti (BCP) model with respect to the 0(2, 1) group and relate the solut...Multiperipheral model; Unitaries1970-05
352 Landesman, Bruce M.Obligation to obey the lawIt is often said that we have an obligation to obey the law just because it is the law. This idea has been espoused in the West at least as early as Socrates, and it is espoused today. It is not the special claim of any particular ideology, but has been held by advocates of most political persuasio...Obedience; Moral; Legal1972
353 Sokolsky, PierreObservation of the reaction νµ + p →νµ + p+We have observed the elastic neutral - current reaction vµ +p→vµ +p and compared it to the quasielastic reaction vµ +n→µ +p. We have measured the ratio of the two reactions to be 0.23 ± 0.09.1976-07
354 Ailion, David CharlesObservation of ultraslow translational diffusion in metallic lithium by magnetic resonanceThe theory of a new magnetic-resonance technique for studying the ultra slow motion of atoms was presented in a previous paper. In this paper, we present its experimental confirmation for the case of translational diffusion in lithium metal. By this technique the mean time between atomic jumps r can...Ultraslow atomic motion; Magnetic resonance1965
355 Reens, Don M.Observations on a Mosquito Flight in Salt Lake CityIn a survey of the mosquitoes of Salt Lake City carried on since 1929, a number of mosquito flights have been observed and recorded. These flights have occured principally in three species of mosquitoes common to region,- Aedes campestris Dyar and Knab Aedes vexans (Meigen) and Aedes dorsalis (Meige...1935-02
356 Brown, Francis HaroldObservations on the stratigraphy and rediometric age of the omo beds, lower omo basin, southern EthiopiaDuring September and October, 1966, the author measured a stratigraphic section for a portion of the Omo Beds, as exposed north of Kalam, Ethiopia. Additional field observations were also made at the time in other parts of the lower Omo Basin. Samples were collected for analysis and for radiometric ...1969
357 Chamberlin, Ralph V.On a collection of chilopods from the East IndiesThe present paper is a report upon' a collection of chilopods received for identification from the Buitenzorg Museum, Java, through the courtesy of Dr. Dammerman,1939-06-28
358 Chamberlin, Ralph V.On a diplopod collection from Barro Colorado Island, PanamaThe present paper presents the results of a taxonomic study of an important collection o f millipeds made bv Mr. Eliot C. Williams, Jr., of Northwestern University on Barro Colorado Island during July and August of 1938. Twenty-three species were secured, these representing •i very interesting and...1940-01-18
359 Battin, Margaret P.On being blue, a philosophical inquiry by William GassOn Being Blue is a remarkable piece of rumination: it toes, wades, pulls its skirt up and immerses itself in the word 'blue.' Blue noses, blue laws, blue devils, blueblood; Gass begins by producing wonder, and we say: / didn't know the word 'blue' could be used in so many different ways. Bluebird, b...1977
360 Chamberlin, Ralph VaryOn centipeds and millipeds from Mexican CavesThis paper is a report on centipeds and millipeds taken in the caves in the states of Vera Cruz, San Luis Potosi, Nuevo Leon and Guerrero by Drs. F. lionet and C. Bolivar and associates of the Escuela Xacional de Ciencias Naturales of Mexico. The material from these caves forms part of an extensive ...1942-11-20

362 Chamberlin, Ralph VaryOn Mexican centipedsThis paper presents the results of a taxonomic study of extensive collections of Mexican centipeds made by Dr. F. Bonet of the Escuela Nacional de Ciencias Biologicas, Instituto Polytecnico Nacional, and Ur. C. Bolivar of the Instituto Enfermadades Tropicales, and their associates. For their generos...1943-02-12
363 Chamberlin, Ralph V.On Mexican MillipedsThis contribution toward knowledge of the diplopod fauna of Mexico is based primarily upon the extensive and important collections made during the last few years by Dr. F. Bonet of the Escuela Vacional de Ciencias Biologicas and Dr. 0. Bolivar of the Instituto Enfermadades Tropicales of the Institut...1943-10-28
364 Chamberlin, Ralph V.On several new American SpidersHerein are described a few species of spiders, from the United States, which were determined as new, while labeling up part of the collection. In the triton-sexpunctcitus complex of the Dolomedes, it was noted that at least four species are represented. Two of the sjjecies were assigned to triton an...1946-03-25
365 Chamberlin, Ralph V.On some Diplopods of the family fontariidaeThe purpose of the present paper is to designate certain new genera in the family Fontariidae occurring in the eastern and southeastern states and to give brief preliminary diagnoses of various new species within these and related genera.1939-07-08
366 Chamberlin, Ralph V.On some genera and species of American MillipedsThe notes and diagnoses in this paper are based primarily upon a small but interesting collection of millipeds recently made in Georgia by Wilton Ivie, and upon specimens in the Field Museum collection chiefly from neighboring sections of the southern states.1943-10-15
367 Lowrance, EdwardOn the early development of Stagnicola Kingi (Meek) the Utah Ribbed SnailGeneral interest in the subject of molluscan embryology has continued in part because of the relation of its problems and processes to those of adult anatomy and ph_ysiology and in part because of its promise of light on the dynamic, developmental process itself. Attention was called to the present ...1934-03
368 Olivera, Baldomero M.On the mechanism of the polynucleotide joining reactionPolynucleotide-joining enzymes (ligases) have been identified in uninfected and phage-infected Escherichia coli (Gellert, 1967; Olivera and Lehman, 1967a; Zimmerman et al., 1967; Gefter et al., 1967; Weiss and Richardson, 1967a; Cozzarelli et al., 1967).

370 Mattis, Daniel C.Operator identity and applications to models of interacting electronsBy correct reduction of some quartic forms in fermion field operators, I eliminate all but a constant and some quadratic terms. I can use this to transform the Wolff model, of a magnetic impurity in a nonmagnetic metal, into a solvable quadratic form in fermions. Applying the same method (with less ...Fermi operators1976-03
371 Templeton, Frederick E.Optimal control of a process with discrete and continuous decision variablesThe task of dynamic optimization consists of manipulating the inputs to a dynamic system (i.e., one in which the state varies with time) so that the system performs in an advantageous manner. This paper presents a systematic technique for solving the problem of optimally controlling a converter ais...Dynamic optimization; Decision variables; Converter aisle; Copper smelter1970
372 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
373 Gesteland, Raymond F.; Atkins, John F.Origin and destiny of adenovirus proteinsLytic infection of human cells by adenovirus proceeds by a temporal expression of genes. Classically two phases have been defined: an early phase, which includes events occurring before the onset of DNA synthesis (8 hours), and a late phase, including events whose existence depends on the onset of...Protein Biosynthesis; DNA, Viral; Adenoviridae; RNA, Viral; Time Factors1975
374 Rees, Don M.Origin of Mosquito producing waters in the vicinity of Salt Lake City, UtahDuring the course of this investigation, from 1929 to 1987, of the mosquitoes in the vicinity of Salt Lake City, some interesting data have been collected on the origin of waters that produce mosquitoes. These data are now sufficient to justify certain pertinent conclusions. As all mosquito larvae a...1939-04-28
375 Normann, Richard A.Oscillations in rod and horizontal cell membrane potential: evidence for feed-back to rods in the vertebrate retina1. Rods and horizontal cells were studied with intracellular recordings in the retina of the toad, Bufo marinus; 161 cells were from the eyecup preparation and thirty were from the isolated perfused retina. 2. Of these cells, 39% exhibited either transient or sustained oscillations of membrane poten...Retina; Photoreceptors; Toads; Adaptation, Ocular1976
