Activity Of Papain On Gelatin Mixtures, Edward J. Ruschmann Jul 1941

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.


Bulletin No. 298 - Wool Scouring Tests In Utah, Alma C. Esplin, Ralph W. Phillips, Milton A. Madsen Jun 1941

Bulletin No. 298 - Wool Scouring Tests In Utah, Alma C. Esplin, Ralph W. Phillips, Milton A. Madsen

UAES Bulletins

Wool, as it is shorn from the sheep, is known as grease wool. The first step in the manufacturing of wool is scouring, or removal of all grease and foreign matter. Within any given grade, as determined by length of staple and fineness of fiber, the yield of clean wool is the primary factor in determining the value of the original grease wool. The price of scoured or clean wool is multiplied by the percentage yield of clean wool to determine the value of the grease wool.


Bulletin No. 299 - Control Of Chlorisis In American Grapes, F. B. Wann Jun 1941

Bulletin No. 299 - Control Of Chlorisis In American Grapes, F. B. Wann

UAES Bulletins

The production of grapes is not a major agricultural industry in Utah, but in some areas of the state the crop is an important adjunct to the general fruit farm. This is particularly true in Washington County where European (vinifera) varieties are grown with considerable success, and in the north central counties where American (labrusca) varieties, especially Concord, are grown for the local markets. In this latter area the nutritional disease, chlorosis, is probably the most serious difficulty encountered in the development of a successful vineyard.


The Geographic Distribution Of Azotobacter And Rhizobium Meliloti In Nebraska Soils In Relation To Certain Environmental Factors, H. B. Peterson, T. H. Goodding Jun 1941

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 …

Analysis Of Rocky Mountain Mule Deer Kill Records Of Five-Year Deer Removal From The Logan River Drainage Of Northern Utah, Wilmur Bartels May 1941

Analysis Of Rocky Mountain Mule Deer Kill Records Of Five-Year Deer Removal From The Logan River Drainage Of Northern Utah, Wilmur Bartels

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Checking stations operated during the deer hunting season serve a two-fold purpose. It has long been recognized that such inspection stations aid greatly in the enforcement of hunting laws through the detection of illegal practices, and in many cases have been set up with this as a primary purpose. A more far reaching objective, however, is the collection of information to aid in the solution of the problems of maintenance of the range and the deer herd, and determination of the quality and quantity of the deer removal.


The Effects Of A Carbohydrate Deficient Diet On The Mouse, Walter Rudolph Sala May 1941

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.

Control Of The Chinch Bug In Nebraska, M. H. Swenk, H. D. Tate Apr 1941

Control Of The Chinch Bug In Nebraska, M. H. Swenk, H. D. Tate

Nebraska Agricultural Experiment Station: Historical Circulars

The chinch bug, Blissus leucopterus (Say), is one of the most injurious insect pests of cereal crops in the United States. Although some damage by it has occurred over a wide area in the United States, the greatest injury has been in the Corn Belt. The years in which the chinch bug appears in destructive abundance come irregularly in cycles of varying duration, and the length of these cycles is largely controlled by the direct or indirect effects of weather upon the bugs. Continued dry weather favors them, while very wet weather brings about their destruction. During the last seven …

A New Fossil Bovid From Nebraska With Notice Of A New Bison Quarry In Texas, C. Bertrand Schultz Jan 1941

A New Fossil Bovid From Nebraska With Notice Of A New Bison Quarry In Texas, C. Bertrand Schultz

Bulletin of the University of Nebraska State Museum (1924–2023)

An interesting and unique bovid skull was reported to the staff of the University of Nebraska State Museum in 1938 by Mr. Alvin McReynolds of Nehawka, Nebraska. The specimen was found in 1933 in a ravine north of Nehawka by Messrs. Merritt and Harold Dodson, brothers. Although the skull was not in place, it appears to have been washed out of a nearby Pleistocene clay deposit by floodwaters. The specimen is well preserved and is of a dark brown, almost black color. In 1938 it was loaned to the Museum for study and photographing but was not obtained as a …


The Ancestral Ursid, Hemicyon, In Nebraska, Edwin H. Colbert Jan 1941

The Ancestral Ursid, Hemicyon, In Nebraska, Edwin H. Colbert

Bulletin of the University of Nebraska State Museum (1924–2023)

During the summer of 1928, a University of Nebraska State Museum field party, composed of Dr. A. L. Lugn and the writer, made a collection of upper Miocene and lower Pliocene mammals in Brown and Cherry counties, Nebraska. This collection was sponsored and made possible by the generosity of the late Hon. Charles H. Morrill.


A Shovel-Tusked Mastodon, Arnebelodon Fricki, From Kansas, Erwin Hinckley Barbour, Claude W. Hibbard Jan 1941

A Shovel-Tusked Mastodon, Arnebelodon Fricki, From Kansas, Erwin Hinckley Barbour, Claude W. Hibbard

Bulletin of the University of Nebraska State Museum (1924–2023)

Since the Amebelodontinae were first announced (Barbour 1927), a number of examples of the genus Amebelodon have presented themselves in various parts of Nebraska, Colorado, and in several places in Kansas. Thus its range has already been materially extended, many skeletal parts added, and the hope kindled that knowledge of this remarkable group of proboscideans is destined to be greatly enriched within the next few years. As may be seen in the accompanying lists of the known parts of Amebelodon preserved in various museums, there are already at hand the bones necessary for the assemblage of a nearly complete composite …


A New Species Of Sphenophalos From The Upper Ogallala Of Nebraska, Erwin Hinckley Barbour, C. Bertrand Schultz Jan 1941

A New Species Of Sphenophalos From The Upper Ogallala Of Nebraska, Erwin Hinckley Barbour, C. Bertrand Schultz

Bulletin of the University of Nebraska State Museum (1924–2023)

The genus Sphenophalos was described by John C. Merriam (1909, p. 319-30), who based his description on a fragmentary horn-core (Uni. of Calif. No. 11887) from the late Tertiary deposits near Thousand Creek in northern Humbolt county, Nevada. Knowledge of Sphenophalos, however, is still confined to this single, fragmented type horn-core (Frick 1937, p. 472) and other fragmental specimens (Furlong 1932, p. 27-36).


Trees And Shrubs Of Kings Canyon National Park, Kenneth M. Stocking Jan 1941

Trees And Shrubs Of Kings Canyon National Park, Kenneth M. Stocking

University of the Pacific Theses and Dissertations

In 1935 I first visited the Kings Canyon area. Since then I have spent many hours wandering through the woods and over the mountains in the area around the old General Grant National Park and the country which is now included in the Kings Canyon National Park. To my knowledge, no complete flora has been made for this vicinity. I consider the following pages to be the beginning of a fascinating work. It is the beginning because this paper includes only plants with woody stems.

The Pipy Concretions Of The Arikaree, C. Bertrand Schultz Jan 1941

The Pipy Concretions Of The Arikaree, C. Bertrand Schultz

Bulletin of the University of Nebraska State Museum (1924–2023)

The pipy concretions of the Arikaree (lower Miocene) of Nebraska and adjacent states were first described by Nelson Horatio Darton (1899, p. 743) as "characteristic layers of hard, fine-grained, dark-gray concretions, often consisting of aggregations of long, irregular, cylindrical masses" (see Figures 30, 32, 34, and 35). The individual pipes vary in diameter from a few inches to several feet, and in length from a few inches to a hundred yards or more. Tests demonstrate that pipy concretions are composed of sand cemented by calcium carbonate. When dipped in acid the cement is dissolved and the concretion is reduced to …
