Estimating Commercial Expansion From Irrigation Development In The Oahe Unit, John Thompson, Ottar Nervik

Agricultural Experiment Station Agricultural Economics Pamphlets (1941-1991)

Commercial activity in an economy that is predominantly agricultural is very sensitive to changes in fanning conditions. It is generally agreed by businessmen in agricultural areas that the success of their business operation is largely dependent upon the number and prosperity of farmers in their trade areas. For this reason business men often encourage proposals to increase the number of farms in their trade areas and support measures designed to improve the economic position of farmers. In South Dakota, where rainfall is considered a limiting factor in agricultural production, considerable interest has been taken in irrigation as a, means for …

Economic Analysis Of Forage Production And Utilization In Dakota And Dixon Counties, Nebraska, Howard W. Ottoson

Nebraska Agricultural Experiment Station: Historical Research Bulletins

Soil erosion remains a serious problem on many Nebraska farms despite programs of financial assistance, technical aid, and education by several national and state agencies. One reason that soil conserving adjustments in land use have not been made by farmers is that considerable uncertainty surrounds the economics of soil erosion control on the farm level. This study is an attempt to increase knowledge and reduce some of the uncertainty with regard to the economics of erosion control in a specific area.

Effects Of Weather-Condition On The Turtle Creek Plankters Near Dallas, Texas, Stanton J. Erickson

Field and Laboratory

An annual temperature cycle exists in fresh waters. This cycle, associated with periods of winter and summer stagnation, and spring and fall turnover, is governed by the addition and loss of heat. The amount of heat (in gram-calories) needed to raise the water temperature from its winter minimum to its summer maximum, is known as the "annual energy" or "heat budget." The heat-gain occurs in the spring, and effects spring-turnover; the heat-loss occurs in the fall, and effects fall-turnover. Over a period of years, the heat gained equals the heat lost (Allee 1939.) Plankters in their life cycles also exhibit …

Farm Labor, Power And Machinery Performance For Selected Operations Under Dryland And Irrigated Conditions In Central South Dakota, James Ulvilden

Agricultural Experiment Station Agricultural Economics Pamphlets (1941-1991)

The problems of farm managers are everlasting. They are constantly in the process of examining alternative methods of production and alter native combinations of resources in an attempt to attain a higher and more stable income. For this farm planning, a vast amount of physical data on the cost and returns of alternative plans is needed. It is important that the physical data be as accurate as possible, because the farm plan is no better than the information upon which it is based. Technological progress has been very rapid in agriculture and thus it is important to keep up with …

On The Status Of Some Arctic Mammals, Robert L. Rausch

Harold W. Manter Laboratory of Parasitology: Faculty Publications

The mammal fauna of arctic Alaska is comprised of about thirty species, most of which are widely distributed. A few of these are essentially nearctic species, having extended their range northwestward during post-Pleistocene time. The majority, however, consists of forms which are either circumboreal in their distribution, or which have closely-related palearctic counterparts-considered specifically distinct hy most North American mammalogists. Sorne of the foremost Old World workers, however, do not agree that Bering Strait constitutes a barrier which effectively separates the Old World fauna from the New.

Studies On The Helminth Fauna Of Alaska. Xiii. Disease In The Sea Otter, With Special Reference To Helminth Parasites, Robert L. Rausch

Harold W. Manter Laboratory of Parasitology: Faculty Publications

During the spring of 1951, the U. S. Fish and Wildlife Service undertook the removal of sea otter, Enhydra lutris (L)., from the Aleutian Island of Amchitka, for the purpose of restocking range from which the animals have long been exterminated. The decision to undertake this activity was influenced by the nature of military operations planned for the island later the same year. The capture and removal of the otter were under the supervision of Mr. Robert D. Jones, Biologist, U. S. Fish and Wildlife Service. Heavy losses among the animals shortly after capture made the venture unsuccessful. Many deaths …

The Effect Of Some Variables On The Numerical Evaluation Of Printing Quality, James G. Dunlap Jr.

Paper Engineering Senior Theses

Introduction

The desire for specific information concerning those qualities of paper, which tend toward satisfactory results in printing, has become of great interest to papermakers and paper consumers. To the paper mill, this information is important in preventing the production of unsatisfactory printing paper. To the printer, such information enables him to determine unsatisfactory paper before it reaches the presses, and also permits him to tell the papermaker in advance the characteristics that are desired in the paper.

Influence Of Additives Upon The Viscosity Of Concentrated Deinking Waste, Richard J. Drexel

Paper Engineering Senior Theses

The literature survey reveals little information relating directly to deinking waste. This waste is composed mostly of coating and filling pigments such as clays and calcium carbonate therefore a study was made along these lines. Hauser (8), and other colloidal chemist, generally agree that clay and other pigment suspensions can be dispersed with certain chemical additives. This is said to be attributed to the active forces of repulsion between the particles which in turn produce a marked effect upon the flow properties. Further studies reveal that the Hercules Hi-Shear viscometer has been useful in analyzing high solids pigment suspensions which …

Polyvinyl Acetate Lattices As Adhesives For Pigment-Coated Paper, Robert L. Harney

Paper Engineering Senior Theses

In recent years, the possibility of using synthetic latices as adhesives in the paper coating industry has caused much interest. The manufacturers of latices uncovered a new market by fostering developmental research in the field of pigment coating binders. Polyvinyl acetate latices were one of the group of products studied in this manner.

In the past, experts in the field of coating believed that synthetic latices could contribute substantial improvements to some optical properties of coated papers over and above that of conventional adhesives. It was also felt that synthetic latices could exhibit higher pigment binding power than conventional adhesives. …

Supercalender Variables (I) The Effect Of Supercalender Pressure On The Physical Characteristics Of Paper, Kenneth L. Maves

Paper Engineering Senior Theses

This work is concerned with the effect of supercalender pressures on the physical properties of paper.

The literature survey shows that very little work has been published concerning the effect of the variables of supercalendering on paper. In this investigation, a study is made of the effect of varied supercalendering pressures on 50 percent rag ledger and coated folder paper. The experimental results show that definite trends were established on physical strength and optical properties when supercalender pressure w as increased.

A Comparison Of The Color Stability Of Certain Rosin Sizing Agents As Influenced By Light And Iron, Raymond L. Janes

Paper Engineering Senior Theses

A literature survey is presented concerning the yellowing of paper with age and the relationships of rosin, light, and iron as factors in inducing this discoloration. The recent chemical modifications of rosin which are applicable for use in the sizing of paper are investigated with the intent of discerning whether or not they exhibit sufficient improvement in color-brightness stability over that of natural rosin to warrant their use in certain high quality papers.

The experimental results indicated only one rosin modification, "Foral", a fully-hydrogenated rosin, having a marked advantage over natural rosin with regard to brightness stability as affected by …

Size Tests Applicable To Writing Surface Versus Aqueous Inks, Md. Mozammel Haque

Paper Engineering Senior Theses

Introduction

Some paper, because of their use requirements are required to be porous and absorbent to liquids, particularly water. Examples of these papers are paper towels, blotters and filter paper. Most papers, however, are required to be resistant to the passage of acquous liquids or vapor. Writing papers, moisture resistant bags, waxed paper and many other classes of paper too numerous to mention fall into the latter groups of papers.

The required degree of resistance to the penetration of aqueous liquids or vapors is brought about through the process of sizing. Sizing may be defined as the addition of materials …

Ecological Observations Upon The Fresh-Water Sponges In Dallas County, Texas, E. P. Cheatum, Joseph P. Harris Jr.

Field and Laboratory

Published distributional and ecological data on the fresh-water sponges of Texas are meager. Besides Marcus Old's (1936) report on sponges collected by us the only other published report for this region is a description of Asteromyenia plumosa by Weltner (1895) from McKinney, Collin County, Texas. Dr. Old reported Spongilla fragilis from a small pond 1½ miles west of Dallas, and from Parson's Slough near Seagoville in Dallas County; Trochospongilla horrida from Elm Fork of the Trinity River, Dallas County; Asteromyenia plumosa from White Rock Lake, Dallas; and Ephydatia crateriformis from the East Fork of the Trinity River in Rockwall County. …

Radiosensitivity Of Mice In Relation To Heightened Metabolic Activity During And Immediately Prior To Exposure To 220 Kv X-Rays, M. Rosalie Henneke

Bachelors’ Theses

The manner in which certain factors influence the susceptibility of protoplasmic systems to ionizing radiations is not as yet well understood. Of prime importance among these factors is metabolic rate; it has been demonstrated that there exists a definite re­lationship between metabolic level and the lethal effects of such radiations. At the outset it must be pointed out that there are two principal problems in this connection; that is to say, radiosensitivity can be studied in relation to metabolic rate prevailing during or subsequent to exposure. One of the most frequently used criterion of radiosusceptability is mortality rate.
