126 DeTar, CarletonMultiperipheral dynamics at general momentum transferWe extend the group-theoretical analysis of the multiperipheral integral equation of Chew, Goldberger, and Low to general momentum transfers. Using a set of variables for the multiparticle phase space analogous to those of Bali, Chew, and Pignotti, we obtain, through the 0(2,1) symmetry, a partial...Multiperipheral model1969-12
127 Capecchi, Mario R.N-formylmethionyl-sRNA as the initiator of protein synthesis.A bizarre fast about Nterminal groups of bacterial proteins. Instead of a random mixture, that the great majority of N-terminal groups were either methionine or alanine. This finding suggested that methionine and alanine constituted start signals for the initiation of polypeptide chains. Alternative...Electrophoresis; Formates; In Vitro; Methionine1966-01-01
128 Chamberlin, Ralph V.New American MillipedsHaving the proportions and general structure of Ischnocybc. It differs from this genus in having the first tergite strongly keeled and hiberculate.

129 Chamberlin, Ralph V.New American Tarantulas of the family aviculariidaeWhile accumulating material for a long needed review of nearctic mvgalomorph spiders, a considerable number of species in the family Aviculariidae have been noted which it seems desirable to diagnose and name at this time. It is the purpose of the present paper to do this. It has been found convenie...1940-05-06
130 Cottam, Walter P.New and extended ranges for Utah PlantsThe following Utah plan ts are not included in Tidestrom's " Flora of Utah and Nevada," nor are any listed specifically for Utah in Rvdberg's " Flora of the Rocky Mountains and A djacent Plains."

133 Chamberlin, Ralph V.New Genera and species of North American ParaiulidaeThis paper presents briefly some results of a preliminary taxonomic study of North American millipeds of the family Paraiulidae in the author's collection. It is based primarily upon a study of the nude copulatory organs which offer the most convenient and dependable characters for the definitions b...1940-03-12
134 Chamberlin, Ralph V.New Millipeds from Peru and adjacent partsThe millipeds described in the present paper form part of the new forms found in the course o f a study of four important collections from Peru, Ecuador and Bolivia which have come into my hands fo r study. One of these lots embraces material in the American Museum of Natural History collected in 19...1955-06-10
135 Mulaik, StanleyNew mites in the family caeculidaeIn a collection of arachnids from the southwestern part of the United States made by the author and his wife, Dorothea, was a series of the little known mites of the family Caeculidae. These are fairly large mites measuring up to 1.6 mm. The common name of rake-legged mites is derived from the chara...1945-03-15
136 Woolstenhulme, Jack P.New records of molluscaRecent work on the molluscan collection of the University of Utah, involving the transferring of sets from the accession lots to the systematic series and the cataloging of the new accessions to the museum, has brought out several unpublished records and many gifts of recent date. Among the former a...1942-05-20
137 Chamberlin, Ralph V.New Southern MillipedsThe twenty-six new species of diplopods heroin named and diagnosed were found chiefly in material from Missouri, Arkansas, Louisiana and neighboring states collected in 1935 and 1936 by Mr. Leslie Hubricht of the Missouri Botanical Gardens and now through his courtesy included in the author's collec...1942-03-23
138 Mulaik, Stanley & DorotheaNew species and records of American Terrestrial IsopodsWhile collecting various arthropods during the past ten years, the authors accumulated a sizable series of Isopods. This paper is a report of a study of certain genera in which seven new species are designated as new and of some species whose ranges are considerably extended.1942-01-15
139 Chamberlin, Ralph V.New spiders from Mexico and PanamaIn the present paper are described eighty new species of spiders, among which are representatives of five new genera, found in two collections from Mexico and Panama respectively. The collection from Mexico was made in the state of Guerrero by Prof. Dr. Schultze Fena, of the University of Marburg, a...1936-11
140 Chamberlin, Ralph V.New tarantulas from the Southwestern StatesIn this paper are presented diagnoses of seven new species of mvgalomorph spiders, one of which, represents the new genus Hesperopholis. The other species are placed in Delopelma. We are indebted to Dr. W. P- Cottam for making the photographs reproduced 0 11 the first three plates. All of these are ...1939-06-28
141 Mulaik, Stanley & DorotheaNew Texas terrestrial isopods with notes on other speciesIn a previous paper (1 ) the authors reported new records and gave descriptions and figures o f new species of terrestrial Isopods. Further studies of their collections reveal additional material of considerable interest, and some of the findings are recorded here. I t is believed that careful colle...1943-08-12
142 Ailion, David CharlesNew two-point calibration method for platinum resistance thermometers for the range 75-400KIn this paper we describe a new method for calibrating high quality platinum resistance thermometers to ±0.01 "C over the temperature range 75-400 K.
