Separation Of The Selenium Compounds In Seleniferous Plant Protein Hydrolysates By Paper Partition Chromatography, Arnold L. Smith
Separation Of The Selenium Compounds In Seleniferous Plant Protein Hydrolysates By Paper Partition Chromatography, Arnold L. Smith
Electronic Theses and Dissertations
In 1943 Franke reported that the protein of "allolied" or "toxic" wheat carried the toxicant, and Franke and Painter in 1935 reported that those "toxic" proteins contained selenium which was in organic combination in the protein. There has been much speculation regarding the possibility of selenium replacing sulfur in the amino acids cysteine and methionine. The toxicity of selenium in selenium analogs of these compounds is similar to that of selenium occurring naturally in proteins seleniferous cereals, which indicated that the selenium may be present in the proteins as the analogue of these sulfur amino acids.
An Annotated List Of The Orthoptera Of Nebraska Part I The Blattidae, Mantidae And Phasmidae, Harold A. Hauke
An Annotated List Of The Orthoptera Of Nebraska Part I The Blattidae, Mantidae And Phasmidae, Harold A. Hauke
Bulletin of the University of Nebraska State Museum
This paper is the first of a series on the Orthoptera of Nebraska. In 1932, while a graduate student at the University of Nebraska, the author began a taxonomic study of the Orthoptera, the result of which was an unpublished List of the Othoptera of Nebraska. The list has been studied and revised.

Preliminary Geomorphological Studies Of The Lime Creek Area & Preliminary Report On The Lime Creek Sites: New Evidence Of Early Man In Southwestern Nebraska, C. Bertrand Schultz, Gilbert C. Lueninghuener, W. D. Frankforter
Bulletin of the University of Nebraska State Museum
PALEONTOLOGICAL and archaeological discoveries were made near Cambridge, Nebraska, by the University of Nebraska State Museum field party in the spring of 1947 (Schultz and Frankforter, 1948, pp. 279-280) . Fossils and artifacts were found in situ at the base of a fifty-foot terrace on Lime Creek (University of Nebraska State Museum Localities Ft-41 and Ft-42) and on Medicine Creek just below the mouth of Lime Creek (Ft-50). Lime Creek is located (Fig. 1) in southwestern Nebraska in the southeastern part of Frontier County. It is a tributary of Medicine Creek which in turn is a tributary to the Republican …
A New Sciurid Of Blancan Age From Kansas And Nebraska, Claude W. Hibbard
A New Sciurid Of Blancan Age From Kansas And Nebraska, Claude W. Hibbard
Bulletin of the University of Nebraska State Museum
The collecting of vetebrate fossils from deposits of Blancan age in Kansas, Nebraska, and Texas during the past twelve years has revealed many interesting forms. Some species have been found to have wide geographic distribution. A large sciurid related to the woodchucks has been recognized from both Kansas and Nebraska and is here described as a new genus and species.

The Goss Lemming Mouse, Synaptomys Cooperi Gossii (Goues), In Nebraska, Edson Fichter, Merle F. Hansen
Bulletin of the University of Nebraska State Museum
In the course of studies on the cestode parasites of microtine rodents by one of the authors (Hansen), specimens of mice were sent to the United State National Museum where they were identified by Dr. David H. Johnson. Two of these microtines proved to be Synaptomys cooperi gossii (Coues). These specimens of Synaptomys (U.S.N.M. Nos. 282343 and 282344), collected at Lincoln, Lancaster County, Nebraska, on September 16, 1946 (male) and November 20, 1946 (female), respectively, are the first ones to be identified from Nebraska.
The Geologic History Of The Bison In The Great Plains (A Preliminary Report), C. Bertrand Schultz, W. D. Frankforter
The Geologic History Of The Bison In The Great Plains (A Preliminary Report), C. Bertrand Schultz, W. D. Frankforter
Bulletin of the University of Nebraska State Museum
THE GEOLOGIC history of the bison in North America is a subject which has received little attention to date. Osteological rather than geological problems have been the main concern of most writers who have so far published. If the geologic history of the bison is to be learned, it will be necessary to devote more time and effort in the field in determining the age of the deposits in which various specimens have been discovered and in making more extensive collections from deposits of known age. Unfortunately the majority of the type specimens have been surface finds and little attempt …

Tertiary Coniferous Woods Of Western North America, George F. Beck
Tertiary Coniferous Woods Of Western North America, George F. Beck
All Faculty Scholarship for the College of the Sciences
Almost four decades have elapsed since Platen (1908), the German paleobotanist, published his report upon the fossil woods of the western United States. Since then no over-all treatment of these materials has been attempted. although Platen overlooked the Pacific Northwest with its abundance of Tertiary petrified woods. The purpose of this paper is to bring knowledge of the western coniferous woods of the Tertiary up to date. In this effort the writer recognizes that much of this information has been accumulated incidentally in the study of the Russell Petrified Forest series of central Washington, and that it is not as …
Range Land Of America And Some Research On Its Management, Laurence A. Stoddart
Range Land Of America And Some Research On Its Management, Laurence A. Stoddart
Faculty Honor Lectures
Although grazing of livestock has been a practice and a profession of man almost from his beginning only recently has range management reached anything approaching a pre~ cise science. Although ' trials and errors over the years brought to light much practical methodology for assuring high production from grazing land, still it remained for the plant physiologist and ecologist to find the whys and wherefores, and to advance new methods and new thoughts which promise to increase productivity still further and at the same time maintain the great range resource.
The peculiar land situation that marked America in her forma~ …
Progress Report On The Ground-Water Resources Of The Las Vegas Artesian Basin, Nevada, George B. Maxey, C. Harry Jameson
Progress Report On The Ground-Water Resources Of The Las Vegas Artesian Basin, Nevada, George B. Maxey, C. Harry Jameson
Publications (WR)
Whether the tremendously increased population acquired by Las Vegas in the years 1940 to 1942 will be retained cannot at present be foretold. However, the valley will undoubtedly be expected to support a considerably larger population than it did at any time prior to 1940, and continually increasing demands on the water supply for innumerable pcacetimc activities must be anticipated. Therefore, a sound evaluation of tho ground water resources of Las Vegas Valley is directly in line with the other wisely progressive planning programs which are now operating or are taking shape in the valley as well as in the …
Nyssa Woods Of The Pacific-Northwest Tertiary, George F. Beck
Nyssa Woods Of The Pacific-Northwest Tertiary, George F. Beck
All Faculty Scholarship for the College of the Sciences
The nyssa gums are one of the modern genera of trees most certainly present among the petrified woods and forests of the Pacific Northwest. Almost every collection from the mid-Tertiary of this region contains a few specimens of typical tupelo or sour gum. These are fine-grained woods which to the unaided eye may be mistaken for conifers.

Ancient Maples Of The Central Washington Region, George F. Beck
Ancient Maples Of The Central Washington Region, George F. Beck
All Faculty Scholarship for the College of the Sciences
When I began work on the petrified logs of the general Vantage area some 13 years ago, it became apparent at once that maple-like woods are commonplace in the main (Vantage) raft forest and slightly less abundant in two rooted units of the Yakima Canyon. So widely do these woods range throughout the structural variations found in modern maples that little success has attended the efforts to assign them to nominal species. The extremes can readily be established but few hints exist as to the boundaries between them.
