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.

Two Newly Discovered Conifers, George F. Beck
Two Newly Discovered Conifers, George F. Beck
All Faculty Scholarship for the College of the Sciences
Two genera of coniferous wood, apparently not listed among the Tertiary woods of the western states, have been recognized in the Percy Train collections from Rainbow Ridge, northwestern Nevada. These two, Tsuga (hemlock) and Chamaecyparis (cedar) bring up to 14 the genera of coniferous wood more or less certainly identified from the period and area in question.
Status Of Tertiary Woods Of The Western States Representing The Juglandaceae, George F. Beck
Status Of Tertiary Woods Of The Western States Representing The Juglandaceae, George F. Beck
All Faculty Scholarship for the College of the Sciences
For many years there has been uncertainty concerning the generic status of some fossil leaves belonging without question to the walnut family as a whole. A review of the woods of Juglandaceae as they have appeared in Tertiary horizons of the western states has suggested which genera are present, and in what proportions their leaves (or other remains) might be expected to appear.

Nitrate Production As Affected By Grain-Crop Residues On The Surface Of The Soil, T. M. Mccalla, J. C. Russel
Nitrate Production As Affected By Grain-Crop Residues On The Surface Of The Soil, T. M. Mccalla, J. C. Russel
Nebraska Agricultural Experiment Station: Historical Research Bulletins
The purpose of this bulletin is to present the data on nitrate contents and nitrate production in tests where straw or stalk residues were left on the surface through subsurface tillage, as compared with check treatments where these residues were plowed under or were absent. Nine of these tests were at Lincoln, Nebraska, and one was at the Hastings, Nebraska, Hydrological Project. Two tests were conducted in 1939, four in 1941, and four in 1942.

Vegetation Of The Northern Part Of Cherry County, Nebraska, William L. Tolstead
Vegetation Of The Northern Part Of Cherry County, Nebraska, William L. Tolstead
Conservation and Survey Division: Faculty and Staff Publications
Agricultural practices in the Great Plains of North America are now in a period of adjustment from a traditional agriculture initiated by pioneer farmers to a grazing economy based upon potentialities of climate and soil. The attainment of a proper system of land use has been retarded in many localities by the lack of definite information concerning the vegetation and its indicator significance. In this study of the vegetation of Cherry County, Nebraska, the interrelations between the plants and their environments are discussed, the dominant species are described, and changes in grasslands caused by seasons, grazing, and climatic cycles are …

Activity Of Papain On Gelatin Mixtures, Edward J. Ruschmann
Activity Of Papain On Gelatin Mixtures, Edward J. Ruschmann
Bachelors’ Theses
Within the Marquette chemical laboratories under the direction and supervision of Dr. John R. Koch, professor and head of the Chemistry Department, many noteworthy advances in enzyme chemistry have been achieved. A new type all glass, single unit viscometer was developed and perfected by Koch and now is the basis of the study of enzyme activity by viscometric methods. The use of this viscometer is not limited solely to work in these laboratories but has also been used with great success in bating and brewing.
The Geographic Distribution Of Azotobacter And Rhizobium Meliloti In Nebraska Soils In Relation To Certain Environmental Factors, H. B. Peterson, T. H. Goodding
The Geographic Distribution Of Azotobacter And Rhizobium Meliloti In Nebraska Soils In Relation To Certain Environmental Factors, H. B. Peterson, T. H. Goodding
Nebraska Agricultural Experiment Station: Historical Research Bulletins
In this investigation a survey of Nebraska soils has been made in order to determine the distribution of the aerobic nonsymbiotic and symbiotic nitrogen fixers of the genera Azotobacter and Rhizobium respectively. In connection with this survey, some of the characteristics of the soils which may bring about this distribution were studied. Up to this time practically no research has been reported on the microflora of the soils of Nebraska. Hence there is little basis for predicting the activity of these organisms under environmental conditions as they exist here. It is hoped that this work will not only supply some …
The Effects Of A Carbohydrate Deficient Diet On The Mouse, Walter Rudolph Sala
The Effects Of A Carbohydrate Deficient Diet On The Mouse, Walter Rudolph Sala
Bachelors’ Theses
Deficient diets have been used extensively as the basis for zoological experiments concerning the metabolism, and dietary requirements of individual animals. The majority of this work has been carried on with the rat as the subject, and resulting external physical variations as the experimental aim. The writer used the mouse as his subject, but, since no literature was available concerning this animal, a few similar experiments performed on the rat will be cited.
