Potentiometric Measurement Of Sodium Chloride In Cheese, Seyed-Hossein Salimi

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The salt content of cheese is usually determined by the American Dairy Science Association (ADSA) (26) procedure. This method is based upon the determination of chloride in the sample, and results are expressed as per cent sodium chloride. The presence of chlorides in cheese other than sodium chloride would introduce error in the results. However, in practice this is not serious except where relatively large amounts of CaCl₂ are added to the cheese milk.

In determining the NaCl in cheese, one would be as justiied in basing his results on sodium analysis as on chloride analysis. An exception would …

A Comparison Of Tests Used In The Selection Of Milk, Roger L. Stephens

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The selection of milk has for many years been based upon the use of bacteriological tests such as the standard plate count, methylene blue, and resazurin tests. Such tests demoted the numbers of bacteria in milk and thus were well accepted as a close correlation of sanitary practices on the farm.

However, improvements in equipment, cleaning procedures, sanitizers and handling methods have greatly improved milk quality over the past decade. The farm bulk tank is a much more efficient system of cooling use in many areas. However, its very efficiency in cooling milk poses many new problems for those engaged …

The Inhibition Of Water Uptake In Sugar Beet Roots By Ammonia, Darrel Marshall Stuart

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Various ammonium salts, urea, aqua ammonia, and anhydrous ammonia are important sources of nitrogen for the fertilization of agricultural crops. While ammonia and its compounds are useful as fertilizers, they can be, and often are, toxic to many plants (Willis and Rankin, 1930; Stout and Tolman, 1941; Raleigh, 1942; Stoll, 1954; Lorenz, 1955; Grogan and Zink, 1956; Allen, 1962; Cooke, 1962; Allred, 1963; Court et al, 1964; Hood and Ensminger, 1964). There are also products which have been designed to retard the oxidation of ammonia and its compounds (Go ring, 1962). It is therefore important that the effects of ammonia …

Physio-Chemical Changes In Relation To The Rest Period Of Peach And Apricot Trees, Hussein Ibrahim El-Mansy

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Many plants require exposure to low temperature for a certain period during each year. This was determined more than a century ago. Understanding this phenomenon, known as the rest period, is part of a larger problem of understanding the factors which determine the ability of an organism to grow. The property of rest is ultimately a property of the actively growing cells, rather than that of the cells involved with protection and support.

Saponin Content And Some Pod And Blossom Characteristics Of Alfalfa As Related To Seed Infestation By The Alfalfa Seed Chalcid, Ronald D. Morse

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The alfalfa seed chalcid, Bruchophagus ruddi Guss., is a jet-black hymenopteran wasp. The destructive nature of this pest has been recognized since the latter part of the nineteenth century. Every year thousands of acres of alfalfa seed are destroyed, with infestation reaching as high as 8 5 percent in some areas. In Utah the chalcid annually ruins from 5 to 25 percent of the alfalfa seed. Much of this damage goes unnoticed, as infested seed is commonly blown out in the trash during harvesting and cleaning operations . The extent of damage is not restricted to the United States. Wherever …

Ionic And Osmotic Effects On Growth, Transpiration, And Osmotic Pressure Of Salt Tolerant Plants, Don L. Chadwick

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Salt tolerant plants have been the subject of considerable interest and study by scientists of arid regions. Ability of these plants to survive and grow in saline habitats has been attributed to such characteristics as: development of high osmotic pressures to counteract the soil moisture stresses, ability to utilize waters of high salinity, and possession of a protoplasm resistant to toxic ion accumulation.

The Initiation Of Infection By Dna From Bacteriophage Lambda, Gerald D. Elseth

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Deoxyribonucleic acid isolated from bacteriophage λ can infect Escherichia coli K12 in the presence of adsorbed helper phage (Kaiser and Hogness, 1960; Kaiser, 1962). The manner in which λ DNA enters the cell and the possible role of helper phage in the penetration process is still not clear. Kinetic studies conducted in this laboratory during the initial stages of infection by λ DNA demonstrate a requirement for helper function during the penetration of an infectious molecule. Further investigation into this problem is needed and was the major objective of this study.

Peracetic Acid Oxidation Of Lignin Model Compounds, Ron Mckelvey

Paper Engineering Senior Theses

Peracetic acid is being used to a limited extent as a bleaching agent for newsprint (1), and to a lesser extent, as a pulping agent, at least at the laboratory level (2). Haas, Schoch, and Ströle (3) report that peracetic acid is an excellent reagent for the preparation of holocellulose from wood. Ogait (4) also found that bleached cellulose could be obtained in 60 to 65% yield from wood and straw by the reaction of peracetic acid at 60 to 80°C. Haney, Martin and Sherk (5), and Poljac (6) have patented methods of oxidizing lignin in wood by peracetic acid. …

Lethal Action Of Ribonuclease For Thermophilic Bacilli, T.L. Thompson, J.M. Shively

Papers in Microbiology

THOMPSON, T. L. (University of Nebraska, Lincoln), AND J. M. SHIVELY. Lethal action of ribonuclease for thermophilic bacilli. J. Bacteriol 91:673-676. 1966.-Exposure of a thermophilic bacillus, NU 47, to 0.2 μg/ml of pancreatic ribonuclease resulted in a drastic reduction of viable cells. The observed lethality is thought to be associated specifically with the ribonuclease, since heat treatment did not diminish activity and the addition of ribonucleic acid to the cells completely eliminated the action of the enzyme. Cells from 2-hr cultures, buffered between pH 6.0 and 7.0, were most sensitive. The lethal action was most pronounced when cells were …

The Effect Of High Velocity Shear On Coating Properties, Richard Wilhelm

Paper Engineering Senior Theses

The chief reason for this work was to investigate the effect of a high velocity shear imparted to a NoKarb clay by a Cowles Dissolver at 5600 rpm.

After 12-hour shearing period drawdowns were made of both the sheared and unsheared clays. Comparisons were then made with respect to brightness, opacity, gloss, Bekk Smoothness, Dennison Wax pick, and K and N Ink Holdout using a starch and a styrene butadiene adhesive.

The Luminometer: A Sensitive Instrument For Measuring Low Amounts Of Oxygen, And Some Applications To Problems Involving The Measurement Of Photosynthesis, Arthur H. Burr Jr.

Student Theses and Dissertations

A new method for the continuous measurement of low rates of oxygen production is described, which is useful for the study of photosynthetic systems. An inert carrier gas flows at a controlled rate through a cuvette, then over a solution of luminol and potassium t-butoxide in dimethylsulfoxide (DMSO). The light generated by the chemiluminescent reaction of luminol with oxygen is measured with a photomultiplier. A constant rate of oxygen production by photosynthesis in the cuvette is seen as a constant displacement from a steady baseline. The baseline is caused by the oxygen impurity in the carrier gas. Electrolysis of water …

The Gross And Microscopic Anatomy Of The Ducts Connecting The Testis And Epididymis In The Mouse, Bruce F. Lindgren

All Graduate Theses, Dissertations, and Other Capstone Projects

In man and other mammals including the mouse, spermatozoa are produced in the testis. Before they are mature, spermatozoa leave the testis and pass through a system of excurrent ducts where they acquire an enhanced capacity for fertilization (Young, 1931; Blandau and Rumery, 1961). These ducts include the tubuli recti, rete testis, ductuli efferentes, ductus epididymidis, and ductus deferens. The contribution of individual parts of this excurrent duct system to spermatozoan maturation is poorly understood.

This study was undertaken to describe the gross and microscopic anatomy of the tubuli recti, rete testis, ductuli efferentes, and their proximal and distal connections …

Changes In Fungi With Age I. Chemical Composition Of Rhizoctonia Solani And Sclerotium Bataticola , David Gottlieb, James L. Van Etten

Department of Plant Pathology: Faculty Publications

The chemical composition of the mycelium of Rhizoctonia solani and Sclerotium bataticola was determined in cells of various ages. The percentage, per unit of dry weight, of soluble amino nitrogen, deoxyribonucleic acid (DNA), ribonucleic acid (RNA), ergosterol, and protein decreased with age in both fungi. Total lipids and fatty acids increased with age in S. bataticola but remained constant in R. solani. Total carbohydrate increased with age in R. solani and decreased in S. bataticola. Fewer changes with age were observed when the results were calculated in ratio to DNA. There was no change in the ratios of protein, …

Influence Of Gibberellic Acid And Indole-3-Acetic Acid On The Morphology And Population Dynamics Of Eudorina Elegans, Dale Robert Frank

Dissertations and Theses @ UNI

Recent intensified . interest in Protista has been motivated largely by simultaneous advances in development of precision equipment and of analytical techniques. The Protista serve well for biological investigation since they are easily obtained, grow well under artificial culture conditions, have a high reproductive potential , and thrive with a mini mum of care. In addition, Protista may be maintained as clonal cultures resulting in identical or nearly identical characteristics, since all organisms are progeny of the same progenitor. The advantages provided by such identical heredities are obvious.

The Effect Of Fines On Relative Bonded Area, Richard G. Bowler

Paper Engineering Senior Theses

Bonding characteristics of the fibers in a sheet of paper have long been, and still are, difficult to isolate in a manner which will give exact quantitative information on the degree or bonding. It is possible to indicate with strength tests different levels or bonding. Other factors -- fiber strength, fiber length, cell wall thickness, etc.,-- also enter into values obtained in these tests and make the assignment of exact meaning to bonding impossible. The subject of a major port of this literature search deals with measurement of another bonding characteristics, relative bonded area or simply bonded area. This again …

The Ultraviolet Induction Properties Of Artificially Lysogenized Strains Of Salmonella Potsdam, Roy E. Olson

Loma Linda University Electronic Theses, Dissertations & Projects

By infection of the non-lysogenic strain of S. potsdam, SP2, with the phages P9a/2 and P9/c three artificially lysogenized strains were isolated: SP2-9a, SP2-9c, and SP2-9ca. SP2 lysogenized with P9a could not further be lysogenized with P9c.

There was evidence from the induction data that the presence of P9c influenced the induction of phage P9a, although P9a did not appear to influence the induction of P9c. Much greater levels of free phage P9a were achieved in induced cultures of SP2-9ca than in induced cultures of SP2-9a.

There were marked differences in induction of both phages P9a and P9c between …

Incidence Of Staphylococcus Aureus On Fomentation Covers, Yvonne Badgley Mcdaniel

Loma Linda University Electronic Theses, Dissertations & Projects

This study was to ascertain whether fomentation covers were contaminated with Staphylococcus aureus prior to being placed on a patient receiving a hydrotherapy treatment.

From a review of literature on the subject of the Staphylococcus aureus organism and from studies of hospital-acquired staphylococcal infection it appeared that: (1) researches had used various techniques for making cultures from fabrics, (2) the Staphylococcus aureus cultures may react in varying ways to the laboratory tests making the classification somewhat difficult, (3) the problem of hospital-acquired staphylococcal cross-infection was present, (4) the role played by the environment in hospital-acquired infections was controversial, and (5) …

The Texas Economy, Stanley A. Arbingast

Journal of the Graduate Research Center

For the past six decades, Texas has been in a process of explosive growth. Since 1900 population has more than tripled, from slightly over 3,000,000 to 10,300,000. The key factors in this growth have been the wide diversity of raw materials available for industry and man's recognition of their value as resources. But in 1965, because many of the nation's dynamic new industries are not oriented to raw materials, the people of Texas need to take a new and searching look at those resources which have been the major basis for economic development, for there is already evidence that as …
