Relation Between Specific Ionization Of Various Radiations And Their Relative Biological Effectiveness In Mammalian Systems, John E. Furchner

Biology ETDs

The relative biological effectiveness of several radiations of differing specific ionizations was determined. The radiation effect studied was impairment of bone marrow function, and the biological test system used was the depression of Fe⁵⁹ uptake by the red blood cells of male Sprague-Dawley rats. The effectiveness of the mixed radiations in the thermal column of a homogeneous reactor was compared with 250-KVP X radiation, and the effect of the beta particles of tritium was compared with that of Co⁶⁰ gamma rays. The effect of the alpha particles of Pu and Ra on bone marrow function was also determined. …

Pustule Formation By Lactobacilli On Fermented Vegetables, T.L. Thompson, W.E. Engelhard, Hilliard Pivnik

Papers in Microbiology

Genuine dill pickles are the product resulting from the fermentation, predominantly lactic, of cucumbers immersed in a brine containing 3 to 4 per cent salt. The brine also contains dill weed and may contain spices and garlic or extracts of their essential oils. Genuine dill tomatoes are manufactured from green tomatoes by a fermentation similar to that used for pickles (Fabian and Wadsworth, 1944).
Lactobacillus plantarum is commonly associated with the fermentation of pickles (Pederson, 1936), although other lactobacilli and some yeasts undoubtedly play a role. A survery of the literature failed to uncover any reports concerning the microbial flora …

Meet Music, Marvel Labrie

SDSU Extension Circulars

"Confidentially, this long-haired stuff is not for me. I don't really know a thing about music, and I can't carry a tune in a bushel basket." With this pessimistic statement, many of us close the door to a whole new world of enjoyment. It does seem confusing when we hear people conversing in longhandled terms about symphonies, sonatas, oratorios, writing styles, and the like. Immediately, we become frightened by their apparent knowledge of music. Don't be misled by that big talk, which may even be done just to impress you. Knowledge of those terms doesn't mean that they enjoy music …

Bulletin No. 375 - Eradication Of Mule Ear With Herbicides And Its Relation To Production Of Forage On Range Lands, D. C. Tingey, C. Wayne Cook

UAES Bulletins

Mule ear (Wyethia amplexicaulis) , also known as green dock and black sunflower, is a tufted perennial with smooth waxy leaves and a thick woody taproot. It reproduces only by seed, yet it is aggressive, and once it becomes established it is highly competitive.

Cattle seldom eat mule ear when other forage is available; however, sheep eat the heads when in full bloom and occasionally consume a small quantity of the young leaves before they completely unfold. Since mule ear is relatively unpalatable, it increases in density with continued heavy use of the range and in some cases …

A Comparative Study In The Field Of Genetics Of The Organic Evolutionary Hypothesis And The Scriptural Account, A. Delbert Rice

Western Evangelical Seminary Theses

Since the beginning of the Church Age, the field of Biblical Apologetics has been the battleground for many acrimonious words and hasty conclusions and the scene of many misunderstandings. Since the advent of the popular exposition of the organic evolutionary hypothesis with Charles Darwin in 1859, many things, based upon a false understanding of the Scriptures or upon a false understanding of scientific evidence, have been said and many accusations made on both sides of the argument. This study has been undertaken to sort from the tons of discussion which have been put forth the few pounds which can be …

Health Resources In South Dakota, George I. Gilbertson, Rena Wills, E. J. Niederfrank, G. J. Van Heuvelen

SDSU Extension Circulars

Improving rural health is a teamwork job--one that deserves all the cooperation that state health and education services, communities, organizations, and individuals can give. From the farm family's standpoint, good health is essential to farming success as well as to happy living.

Shelterbelt Care, E. K. Ferrell

SDSU Extension Circulars

Weeds affect young trees in the same way they affect other crops. Weeds rob trees of moisture, plant food and light. This often results in the death of most of the trees. Those that do manage to live are stunted. Planting a shelterbelt is a waste of time, money and land unless the planting is cultivated throughout its early life. Your young shelterbelt trees need the same care as any other row crop until they are big enough to shade out the weeds and grass. Results of an experiment carried out at South Dakota State College show how important clean …

The Use Of Lactic Acid In The Manufacture Of Cheddar Cheese From Milk Containing An Antibiotic, Elmer George Jr.

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The manufacture of cheddar cheese is greatly dependent on bacterial growth for acid production. The quality of cheese depends upon the type and extent of microbial activity.

An important function of the lactic fermenting bacteria is the production of acid resulting from cellular metabolism. If little or no acid is production of acid resulting from cellular metabolism. If little or no acid is produced the resulting cheese will have an inferior body, flavor, and texture and may even cause the cheese to be used as grinders.

The Biology And Seasonal Distribution Of Eucalliphora Lilaea (Walker) In Cache County, Utah, Robert P. Olson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The association of: flies with man has been recorded through many centuries. In nearly all of these records the association is one of discord rather than harmony. In the Book of Exodus, 8:24, in the King James version of the Old Testament, we can read, "...and there came grievous swarms of flies into the house of Pharaoh, and into his servants' houses; and in all the land of Egypt the land was corrupted by reason of the swarms of flies." Centuries later the "grievous swarms of flies" 'were associated with a particular disease by Mercurialis. In 1577 he expressed the …

Survey And Evaluation Of Big Game Exclosures In Utah, Stanford Young

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

An "exclosure" is defined by Daubenmore (1940) as an experimental area which is protected from the activities of a particular class of animals by a barrier such as a fence or screen thereby controlling a single factor of environment, namely, the animal influence.

Several different types of exclosures are employed by the land management agencies in Utah. Small portable "paddocks" a few feet square are extensively used to gauge seasonal grazing pressure by livestock. Permanently fenced areas, ranging up to many acres in size, serve to demonstrate the effects of livestock use on the range. Another modification is the "big …

Evaluation Of Stream Bottom Fauna Sampling Techniques As Used In The Logan River, Donald C. Hales

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Since the square-foot bottom sampler was described by Surber (1937) it has been the principle instrument used for quantitative studies of the bottom fauna in riffle areas of streams. However, little has been written concerning the actual number of square-foot samples necessary to describe stream bottom fauna in terms of the number or volume of organisms.

A Study Of Aquatic Insects Of Logan River, Utah, Daood Salman Mutlag

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

An Economic Evaluation Of Selected Treatments For Avian Botulism In Waterfowl On Utah Marshes, 1953-54, Donald A. Smith

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Each year thousands of western waterfowl succumb to disease, predators, mechanical injury and other decimating factors . Based on a review of records it is conservatively estimated that an average of 25,000 ducks have succumbed to botulism on western marsh areas annually.

In a recent study, the United States Fish and Wildlife Service valued each duck and goose at $8.00 (McLeod, 1950). Applying this value to the estimated annual numerical loss, a total of $200,000 has been lost each season in mortality of western waterfowl from botulism. Control of this malady would reduce annual waterfowl and monetary losses.

Seeds In The Forest Floor Of The Ponderosa Pine Type, James T. Krygier

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Regeneration of forest stands is often complicated by the establishment and competition of brush on logged and burned-over areas. The encroachment of brush in the ponderosa pine type of Idaho, particularly Ceanothus velutinus, Dougl. presents a difficult problem to the forest manager. The brush competition severely reduces the growth rate of associated trees, thus extending the period necessary to grow a crop of trees. This situation may seriously limit the economic production of a wood crop of ponderosa pine.

Factors In The Development And Restoration Of Waterfowl Habitat At Ogden Bay Refuge Weber County, Utah, Noland F. Nelson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Millions of acres of marshland have been destroyed by the industrial and agricultural development of this continent. Drainage, water diversion, land leveling, and some other factors which destroyed waterfowl habitat were in most instances essential steps in man's progress; but water pollution, unwise drainage, and other soil and water abuses were tragic and unessential steps in our history of land exploitation that have destroyed vast acreages of habitat. The future of waterfowl on this continent hinges upon the success of restoration or new marsh development to replace this destroyed habitat.

Effects On Urinary Metabolites Of Rats Fed Various Edible Fats, Cleve R. Winkel

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

For many years, substitutes for butterfat have been the subject of much controversy. Their acceptance as being nutritionally equal to butterfat has often been question. The importance of this problem lies primarily in its economic and nutritional significance.

A recent study of public attitudes toward dairy products conducted by Alfred Politz Research, Inc. for the American Dairy Association, shows that 48.4 per cent of the population believed that butter is a more nutritions food than oleomargarine. Only 6 per cent thought that oleomargarine is more nutritious while 27.2 per cent believed they are about the same. The remainder, 18.4 per …

Linkage Relationships In Group Iv In Barley, George W. Wheatley

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The development of new and better varieties of plants through plant breeding is essential to meet certain needs of a changing world. Genetics and a knowledge of its principles are the basis for such improvement.

Barley has been used rather extensively in linkage relations studies. Its desirable characteristics are: (1) interspecific fertility and relative ease of hybridization, (2) numerous characters that are easily differentiated, (3) its commercial importance as a crop and (4) there are seven chromosome pairs in each of the four cultivated species.

More than one hundred characters in barley have been investigated. Seven linkage groups in which …

Lactation Curves Of Holstein Cows As Influenced By Age, Gestation, And Season Of Freshening, George Edward Patterson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Lactation curves of dairy cows have been studied by dairy scientists for many years. The effects of various hereditary end non-hereditary influences on the lactation curve have been observed. Factors have been developed to standardize production to a common basis, correcting for differences in age, length of lactation, milking per day, gestation and environment.

Phenotypic Variations Of Kochia Scoparia, Kenneth Malcolm Benson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Kochia scoparia (L.) Schrad. has had limited use as a forage crop during the past fifteen years in parts of the western United States, Canada, and Argentina. Erickson and Moxon (1947) reported kochia* to be a good emergency feed for sheep and cattle during dry years in South Dakota. Salguero (1946) said that this species could be utilized in Argentina as silage or pasturage if harvested before flowering. Bell, et al. (1952) in Saskatoon, Canada studied this species in a comparison with other introduced plants and reported that it seemed to have desirable nutrient characteristics for livestock roughage. Plummer …

Determination Of Digestibility Of Lignin By Mule Deer, Robert B. Turner

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The conflicting problems involving the herds of mule deer (Odocoileus hemionus) are of major interest throughout Utah. Individuals who are affected the most are sportsmen, ranchers, fruitgrowers, sanitation engineers, home owners, federal administrators, and big game managers. Mainly, the problems arise as a result of insufficient forage, especially on the winter range. Here, factors such as increased deer numbers, decreased range productivity, severe winters, and expanded agricultural activity make more acute the problem of a naturally critical season.

Restoration of forage by artificial measures may be necessary as a management solution for certain areas. Range rehabilitation, rather than …

A Study Of The Winter Foraging Habits Of Mule Deer In Enclosures In Northern Utah With A Test Of The Half-And-Half Sampling Technique, Donald R. Flook

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Mule deer provide recreational bunting to a large number of sportsmen in Utah, and also have a high aesthetic value.

Prior to settlement, deer are believed to have wintered in the valleys and lower foothill areas. However, in northern Utah agricultural development bas removed many valleys and lower foothill areas from the available winter range. The winter deer range in this area has therefore been restricted to a relatively small area of foothill country, and low elevation mountain slopes and benches.

Chemical Thinning Studies On Peaches In Utah, Ramzi Mustafa Khalidy

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Investigations on chemical thinning of peaches by use of blossom and post blossom sprays have been in progress since the last decade mainly in the United States, Canada, and some European countries. Horticulturists are attempting to find new means to minimize the expense of hand thinning. The high cost of the hand thinning operation has caused many growers to underestimate the importance of this practice, and as a result their orchards have fallen into the biennial bearing habit. In addition, the fruit from un-thinned orchards was not acceptable on the market since it was small in size, lacked color, and …

An Economic Evaluation Of Feeding Sucrose To Beef And Swine Prior To Slaughter, Douglas C. Strong

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Animal feeding rations have long included carbohydrates as a primary constituent. Grains are included in most animal fattening rations, and the by-products of sugar beets have been used f or many years in livestock feeding (Kutish 1950 b). The use of molasses in commercial feed mixes in 1899 made possible its extended use in animal feeding practices (Hall 1950).

The Response Of Barley To Soil Moisture Tension And Fertilization, Mahmood Agah

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Barley is one of the important crops in many of the irrigated regions of the world. It is an important crop in Iran for both human consumption and livestock feed. In the United States and Europe it is used for livestock feed and beverages.

The income from this crop is moderate in comparison to that from other major agricultural products.

Barley production has a definite place in the economy of the region, because it requires only a small amount of care. It can be readily grown on poor lands. One of the factors contributing to the increased acreage of barley …
