Bulletin No. 373 - Biennial Report Of The Utah Agricultural Experiment Station, 1952-1954

UAES Bulletins

Our way of life is based on the ability of our agriculture to produce abundantly, efficiently, and at a low cost; and the position of agriculture today is largely a result of the research efforts of the state agricultural experiment stations and the United States Department of Agriculture. In the 66 years since the establishment of the Utah Agricultural Experiment Station, its scientists have found solutions to many of the problems peculiar to its location, topography, and climate. It is logical to rely on these same research forces to solve the problems of the future.

During the past biennium a …

Influence Of Atmospheric And Soil Moisture Conditions On Diurnal Variations In Relative Turgidity Of Potato Leaves, H. O. Werner

Nebraska Agricultural Experiment Station: Historical Research Bulletins

The experimental work reported herein was planned to determine: 1. The extent and nature of the changes of the relative turgidity (R.T.) of leaves of the potato plant during the diurnal cycle. 2. The extent to which R.T. of potato leaves is influenced by atmospheric conditions, soil moisture, variety and age of plants. 3. The extent to which visible evidence of water shortage in leaves is indicative of water loss from them as revealed by R.T. and the extent to which this relationship varies with different varieties. 4. The nature of the relationships between morphological characteristics of leaves and stems …

Music And You, Adele Clark Sudlow

SDSU Extension Circulars

After you have selected the best phonograph that you can afford, preferably one with three speeds (78 rpm, 45 rpm, and 33½ rpm), you are ready to begin your home record library. Long-playing records withstand rougher treatment than do the 78's, are easier to store, and will play up to thirty-two minutes per side without interruptions. They're not literally "unbreakable," but they are tough.

South Dakota's Farm Accident Toll, Agricultural Extension Service, South Dakota State College

SDSU Extension Circulars

Facts regarding farm accidents are scarce. A suggestion was made by the state safety director, Carroll Stinson, to the agricultural engineering department that a newspaper clipping survey be made to determine in what areas an educational program might best be developed to cut down on the occupational hazards of modern agriculture. One hundred fourteen of the 185 weekly and eight of the 12 daily papers cooperated in making this survey. Agricultural engineering students clipped out accident reports each week from these papers from November 1, 1952 through October 31, 1953. This survey was restricted to on-the-farm accidents except those accidents …

The Influence Of Pith Cells On The Papermaking Characteristics Of Pulp From Bagasse, Miguel A. Cabrera

Paper Engineering Senior Theses

Literature Survey

Introduction

The fact that the need for paper products is increasing in an unparallel manner with the wood resources available at the United States market, has open the field for research studies in the development of new raw materials.

Bagasse has been a waste product submitted to intense laboratory investigation due to the fact that is a world available and relatively cheap fiber. Its use as a papermaking material has been investigated over a 100 years. Its development has been attacked by the different and contradictory opinions obtained from pilot plant runs and lack of knowledge techniques in …

The Performance Of Sodium Hypochlorite And Sodium Hypobromite As Bleaching Agents At Varying Levels Of Hydrogen Ion Concentration, Ted Jewson

Paper Engineering Senior Theses

Limited information was found in literature survey on the bleaching of wood pulp by means of hypobromites. Experimentation showed that the addition of sodium bromide to sodium hypochlorite results in accelerated bleaching. The optimum pH range for bleaching was found to be higher in presence of hypbromites than in straight hypochlorite bleaching. The maximum brightness values obtained in bleaching with either straight sodium hypobromite or with mixtures of hypochlorite and hypobromites were lower than those obtained with sodium hypochlorite.

Possible Use Of Chlorine Dioxide For Bleaching Deinked Paper Stock, Donald E. Thorton

Paper Engineering Senior Theses

The literature survey shows that chlorine dioxide can be used to bleach virgin pulp to a high brightness. The purpose of chlorine dioxide is to preserve the strength of the pulp.

The purpose of this thesis was to find out if chlorine dioxide could be used to preserve the strength of deinked paper stock.

Paper stock was found to lose strength when bleached with calcium hypochlorite and mixed with virgin pulp the loss of strength carried over in the mixture.

When the paper stock was bleached with chlorine dioxide, there was no loss of strength in the paper stock.

50 Years Of Research At The North Platte Experiment Station, W. W. Burr, J. C. Adams

Nebraska Agricultural Experiment Station: Historical Circulars

The North Platte Experiment was established fifty years ago. So many changes have occurred since then that few people remember why research in dry land agriculture was started in Nebraska and other Great Plains states. In order to get a proper perspective, it may be well to consider some early history.

Bulletin No. 368 - Drainage Of The Cache Valley Lowlands, Willard Gardner, Orson W. Israelsen

UAES Bulletins

Now, slightly more than a hundred years since irrigation was first started in the West, many of the low-lying valley lands produce only poor quality pasture grasses because of waterlogging, salinity, and alkali. Other lands now produce only light crops of wild hay, and still other land areas are almost wholly non-productive because of the concentration of excessive quantities of harmful salts. This waterlogging is largely a result of irrigation on the higher lands, although rain and snow waters aggravate the situation. The water not used by the highland crops seeps into the lower areas, bringing harmful salts to the …

The Adaptation Of The Neutron Scattering Technique Of Soil Moisture Determination To Field Application, Robert L. Uhler

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

At the present time there is a recognized need for a better means of measuring soil moisture in situ. Soil moisture measurements are required in fundamental studies of soil moisture flow and soil-plant-water relationships as well as in practical studies in irrigation practices. Various phases of engineering also utilize soil moisture data, for example, soil moisture determinations are made during the construction of earth dams, road cuts and fills, and under airfield runways. The desired method should be quick, reliable, and adaptable over the moisture range from oven dryness to saturation.

Research in nuclear physics has revealed the neutron …

The Effect Of Limited Moisture Supply At Various Stages Of Growth On The Development And Production Of Hybrid Corn, Ralph E. Campbell

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Corn occupies from 25 to 30 percent of the crop land harvested in the United States. In recent years the acreage devoted to corn in this country has been decidedly greater than that devoted to any other cultivated crop. In 1944 its dollar value exceeded the combined values of wheat, barley, rye, grain sorghums, and cotton.

Although South Dakota lies on the northwestern fringe of the corn belt, the corn crop is one of the most important in that state. Corn production in that area is somewhat unstable because of drought. Corn often fails to reach full maturity before the …

Weed Control Investigations On Some Important Aquatic Plants Which Impede Flow Of Western Irrigation Water, United States Department Of The Interior, Bureau Of Reclamation

Elusive Documents

During the past 50 years, the acreage of land placed under irrigation in the western United States has increased greatly to meet the growing demand for food and fiber production. To provide this water for crop production it is necessary not only for river waters to be impounded and irrigation canal distribution systems established but also for the irrigation waterways to be free of obstructing plant growths which impede the flow of water. This requires various types of weed control measures in order that originally designed carrying capacities of the waterways may be maintained. Methods involving new techniques developed mostly …

The Influence Of Locust Bean Gum On The Strength Characteristics Of Handsheets Under Varying Ph Conditions. A Study Of The Effect Of Alum Or Hydrogen Ion Concentration, Robert J. Witters

Paper Engineering Senior Theses

A literature survey concerning the addition of locust bean gum to beaten pulp and the resulting strength characteristics imparted to handsheets through the addition of the gum has been undertaken. Although much literature can be found, hardly any detailed information can be extracted on the effect of alum or hydrogen ion concentration. Therefore, the aim of this paper is to draw some conclusion, through laboratory work, as to any possible change, due to pH or alum, in the strength characteristics of handsheets containing locust bean gum.

The first part of this thesis will be a brief review of work that …

The Growth Of Pathogenic Bacteria In Soluble Oil Emulsions, Hilliard Pivnik, W.E. Engelhard, T.L. Thompson

Papers in Microbiology

Mineral oils, when emulsified with materials such as soaps of petroleum sulfonates, fatty acids, abietic acid or resin, are referred to as soluble oils. These oils, mixed with water, form stable emulsions which are universally employed as coolants and lubricants for drilling, cutting, and grinding of metals. In addition to the emulsifying agent, soluble oils may also contain fatty oils, disinfectants and emulsion stabilizers.
The oils supplied by the manufacturer are sterile, but when mixed with water in the machine shop they support microbial growth (Duffet et al., 1943; Fabian and Pivnick, 1953; Lee and Chandler, 1941; Page and Bushnell, …
