The Effect Of Galacto-Mannans On Handsheets Made From Softwood, Hardwood Or Rag Pulps, Thomas R. Murwin

Paper Engineering Senior Theses

Some published information reports that galacto-mannans, when used as strength producing beater additives, do not effect significant strength increases in hardwood pulps. In order to investigate this problem further, six pulps covering a wide range of pulping processes and chemical compositions, were evaluated before and after the addition of locust bean gum, a galacto-mannan, to the pulp.

The results obtained indicate that galacto-mannans do favorably affect the strength properties of hardwood pulps. Substantial increases in bursting strength, tensile strength and folding endurance were noted for all the hardwood pulps employed, as well as for a rag pulp. These strength increases …

An Evaluation Of Selfing Techniques For Agropyron Elongatum, Keith I. Matheson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Tall wheatgrass Agropyron elongatum (Host) Beauv. has gained in importance since its introduction into the United States in 1909 from its native habitat on saline meadows and seashores of Southern Europe and Asia Minor. This very late-maturing, coarse, nonlodging 2 1/2 to 6-foot-tall bunchgrass was discarded in Utah in 1919 for being too aggressive. It is now under production in the intermountain and other regions because of its cold and drought tolerance as well as for its salt tolerance and its ability to make excellent fall and spring recovery. According to Weintraub (1953) this salt-tolerant plant gives high yields of …

Banding And Marking Methods In Studying Seasonal Movements Of The Sharp-Tailed Grouse In Morton County, North Dakota, Albert T. Klett

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The Great Plains variety of the sharp-tailed grouse Pediocetes phasianellus jamesi Lincoln was the predominant upland game bird during the exploratory and early settlement period in North Dakota (Coues 1874 and 1878, Larson 1928, and Williams 1926). Since then its status has diminished as the prairie grassland gradually was converted to intensively used pastures and cropland. Although the sharptail is still abundant enough in its remaining habitat to provide for liberal annual harvests, further demand on these lands by a growing human population will make it necessary to apply game management measures other than hunting regulations if the sharptail is …

Thermodynamics Of Phosphate Absorption On Several Charcoals, James Duncan Beaton

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Phosphorus has long been recognized by agriculturists as being one of the elements essential for plant growth. Although the total phosphorus content of a soil may be high, the amount of phosphate actually available for plant growth is often low. Many agencies such as inherent low solubilities of phosphate compounds, adsorption on Ca C03, adsorption in the diffuse double layer of clay micelles, and chemical precipitation of phosphate which refers to the removal of phosphate ions from solution and their chemical bonding to the solid phase have been studied to explain the lack of phosphate availability.

The Effect Of Temperature On The Tension Of Water In The Soil, Gordon Stewart

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The tenacity with which water is held in the soil is an important factor in determining the availability of water to plants. It is this attraction for water by the soil particle which is the basic phenomenon of soil moisture tension. Soil moisture tension may be defined as the pressure difference that must be maintained across the wall of a porous cup in order to attain a zero transfer rate between water in the soil, which is subject to surface-force action, and water in the cup, which is not subject to surface force action.

Combining Field Fertilizer Trials With Soil Tests In An Effort To Obtain The Most Suitable Soil Nitrogen And Phosphorous Tests For Southern Alberta, Einard Haniuk

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Under dryland farming operations, the use of fertilizers is often restricted due to limited crop response arising from limited seasonal moisture. Once this dryland area is brought under irrigation, there is increased use of fertilizers and increased demands for greater exactness in amounts of fertilizers to apply, due to efforts which are made to increase the returns from the land by introduction of new farming techniques and crops.

The Measurement Of Physical Properties Of Field Soil, Wilbur Sloat

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Since the beginning of soil tilled agriculture, there have been many controversies as to the proper kinds and amounts of soil tillage required to establish and produce a crop. These controversies have ranged far and wide between farmers, extension service personnel, agricultural specialists, in fact almost every person connected with agriculture has his own unique concept of what constitutes proper tillage. The concepts vary widely from a no tillage program, for certain perennial row crops, to the extreme dust mulch program.

Breakfast Habits Of Some Utah School Children, Marlene M. Stegelmeier

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

During the last 10 years, much emphasis has been placed on the importance of breakfast for people of all ages. Nutritionists have pointed out that persons who eat a hearty breakfast show fewer signs of mid-morning fatigue, have or develop better work habits, and do not get as hungry as those who eat little or no breakfast.

Many people do not realize the importance of starting the day with a good breakfast. The 12 to 13 hour fast which the body undergoes from the evening meal until breakfast time requires the consumption of an adequate breakfast. Many poor breakfasts may …

Comparative Study Of The Composition And Quality Of Bulk Tank Milk, Kay M. Nilson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

During the past decade, many changes have taken place in the dairy industry. At the present time, the industry is endeavoring to improve the quality and handling of milk. This is being accomplished by new equipment and improved methods.

In recent years the handling and transporting of milk by means of the ten gallon can is being replaced by the bulk tank system. With improved farm and truck tanks, milk can be cooled rapidly and stored at a lower temperature.

There are a few problems pertaining to quality, fat tests and weights in handling milk in bulk tanks. Among the …

The Relative Saponin Content Of Alfalfa Varieties In Utah As Measured By Chick Growth Depression, Morris Dean Wilding

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Bloat among ruminants is not new to farmers or scientists. One learns from a Roman author's description of this ailment written in 60 A. D. that the symptoms have changed little since that time. Literature also records that the treatments used today for the prevention and relief of bloat are similar to those prescribed by the early Romans (Anonymous 1954).

A Study Of The Root Rot-Nematode Complex And The Comparative Yield Of 17 Varieties Of Alfalfa In Washington County, Utah, J. Clair Theurer

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Alfalfa is the major forage crop in the state of Utah. It is especially important in Washington County where mild temperatures allow the production of 4 to 5 cuttings each year, and where the dairy industry is increasing.

A Comparative Study Of Milk Solids And Corn Syrup Solids In The Manufacture Of Sherbets, George C. Walker

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Burke says, "Product inferiority constitutes the greatest menace to the success and progress of any industry." The ice cream industry is no exception. Improvement in the quality of dairy products is a challenge that always faces the industry. Today's products are good, but they can be improved, Sherbet is one product that should be improved most. Many ice cream manufacturers are losing a great potential market because sherbets generally are of poor quality.

The Use Of Branchiostegal Rays To Determine Age Of Lake Trout Salvelinus Namaycush Walbaum, Ross Vivian Bulkley

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Any method used in aging fish must fulfill certain requirements to be satisfactory. If the method is inaccurate, naturally little reliance can be placed upon its use. If considerable study of the method and much practice are required before accurate readings can be obtained, the method will not come into widespread use. The requirements of an aging method, then are that it must be accurate and comparatively easy. The scale method for aging lake trout (Salvelinus namaycush Walbaum) unfortunately does not fulfill these requirements. It has always been difficult to tell the age of lake trout by the examination …

The Alkali Tolerance Of Tall Wheatgrass, David L. Carter

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Alkali land occurs adjacent to nearly every extensively irrigated area. Much of this land is too alkaline to produce profitable crops. Each year thousands of acres or land are going out of production because or increasing alkalinity. This presents one or the most acute problem which confronts irrigation agriculture today.

Cost And Efficiency In Producing Sugar Beets In Utah County, Utah, 1951, Randolph Lamar Larsen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Man has always included some form of sugar in his diet. Only in the past two centuries has sugar been developed as an individual food. During that time vast amounts of money and time have gone into the development and improvement of sugar. In 1747, a German chemist by the name of Andreas Marggraf proved that sugar beets contained sugar. One of his pupils, Franz Karl Achard, in 1799 gave further evidence of this fact by his experiments.

Effect Of Hay Or Rate Of Grain Supplementation On Performance Of Lactating Dairy Cows Fed Clipped Pasture Forage, Clive Wendell Arave

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Pasture is considered one of our most important agricultural crops, contributing more than one third of all feed consumed by livestock in the United States. High quality pasture has been recognized to be highly important in efficient milk production. It has been shown, however, that good pasture must be supplemented by concentrates if milk production is to be maintained at a high level.

A pasture mixture developed at the Utah Agriculture Experiment Station has yielded considerably more total digestible nutrients per acre than other roughages or farm grains commonly grown in Utah. Concentrates tend to be relatively more expensive than …

The Effects Of Hunting Season Length On Comparable Pheasant Populations, Temple A. Reynolds

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

For many years sportsmen have speculated that hunting limits pheasant populations. With the abolition of the Pheasant Game Farm program in Utah in 1953, this popular concept gained much impetus with the result that, because of public disfavor to a longer season, a 3 to 5 day season on pheasants is the maximum that has been called in northern Utah and this only in areas classed as "better" pheasant habitat.

In contrast to the short seasons in Utah, pheasant seasons in southern Idaho have been from 8½ to 15½ days long for the past 10 years, and will be even …

Evidence Against The Transmission Of Staphylococci By The Mosquito Culex Tarsalis, John R. Molenda

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Staphylococcal synovitis is a pathological condition of birds involving primarily the wing and leg joints. It is frequently referred to as arthritis, osteoarthritis, bursitis, hock disease, staphylococcosis, and weak leg.

The disease has been reported throughout various parts of the world as having been found in a great variety of avian hosts including pheasants, chickens, pigeons, canaries, geese, ducks, grouse, and turkeys.

Miner (1945) presented results of a survey made on turkey diseases in Sanpete County, Utah, which indicated staphylococcal synovitis to be responsible for the greatest numbers of deaths. His report cites this infection as having been found in …

Green Rot Of Apricot, Abdul Karim N. Alrayis

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This disease, also called jacket rot of apricot, was first though to be similar to a disease caused by a fungus found in central California. The Utah disease was first noted in 1953, in the Henry Hall Chinese apricot orchard at North Ogden. It was not very severe in 1953, but in 1954 and 1955 it affected half of the crop. In 1956 the disease could not be found in the orchard. Infection occurred in young green fruit resulting in brown to black necrotic lesions which varied from 1/4 to 3/4 inches in diameter. Infected fruits usually dropped from the …

Some Supplementary Studies With Wheat Proteins, Gerald G. Porter

Loma Linda University Electronic Theses, Dissertations & Projects

[Abstract Not Included]

Introduction The importance of selecting only foods containing proteins of high nutritive value has been somewhat over-emphasized in the past because of the failure to recognize the possibility of supplementary relationships among proteins that are not of high quality. Hart (11) has wisely suggested that a food should not be relegated to an inferior class because its proteins, when fed alone, are not of high biological value. Sherman (31) has reminded us that with a knowledge of the nutritional chemistry of the proteins of various foods, it becomes relatively easy to utilize their supplementary relationships so that …

The Backcross Method In Breeding Tomatoes Resistant To Fusarium Wilt, Joseph L. Peterson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Many times the plant pathologist and plant breeder are confronted with a plant disease which requires the development of a resistant variety in a limited time. Any breeding program which requires selection from a large population during each segregating generation to insure the right genetic combination will, of course, lengthen the period which it will take to develop this resistant variety. The backcross method of plant breeding, in many cases, helps the plant pathologist and plant breeder develop resistant varieties containing characteristics similar to those of the desired parental type within a shorter period of time.
