Liquid Loss From Glass Jars Processed In The Pressure Cooker, Arnold E. Baragar Nov 1949

Liquid Loss From Glass Jars Processed In The Pressure Cooker, Arnold E. Baragar

Nebraska Agricultural Experiment Station: Historical Research Bulletins

Home canners and extension home economists have inquired frequently why much liquid is sometimes lost from glass jars of food processed in the pressure cooker. At an extension service Home Canning Research Conference held at Kansas City, December, 1946, state extension agents requested research on this home canning problem, because no published reports were available. This bulletin is a report of experiments with glass jars processed in a pressure cooker to determine (1) conditions that allow much liquid to be expelled from jars, (2) conditions that reduce liquid loss to a negligible amount, and (3) the physical conditions involved in …

A Study Of Saponification Rates As Characteristic Of Esters, Thomas F. Mitchell Jr. Jun 1949

A Study Of Saponification Rates As Characteristic Of Esters, Thomas F. Mitchell Jr.

Bachelors’ Theses

The saponification of esters has been the subject of considerable study, and the technology of manipulation of the reaction well defined. As a result, the reaction has become a quantitative standard for ester analysis. However the comparison of the rates of this reaction with various esters as charaeteristic of them has received little consideration compared to the course of the reaction. The work of Mr. F. E. Adler on the adaptation of fat constants to waxes suggested the problem. The thesis will attempt to ascertain any significant differences in the saponification rates of various esters with regard to their characterization.

A New Elasmosaur From The Eagle Ford Shale Of Texas: Systematic Description, S. P. Welles May 1949

A New Elasmosaur From The Eagle Ford Shale Of Texas: Systematic Description, S. P. Welles

Fondren Science Series

The elasmosaurs were marine reptiles, plesiosaurs with extremely long necks and proportionately very small heads. The larger individuals of the Upper Cretaceous attained a length of forty feet, with necks over twenty feet long. Their limbs were so highly modified into paddles that progress on land must have been extremely difficult, if not impossible. Their long sharp teeth indicate a fish-eating habit, and this has been confirmed by the fossilized stomach contents. The fish were evidently gulped down whole and ground up in a gizzard-like organ which contained stomach stones.


The Diet And Daily Forage Consumption Of An Experimental Herd Of Sheep On Utah's Winter Range, Lee A. Sharp May 1949

The Diet And Daily Forage Consumption Of An Experimental Herd Of Sheep On Utah's Winter Range, Lee A. Sharp

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The forage produced on Utah’s winter range is generally deficient in some nutrients that are required for the phase of sheep production that takes place on these ranges. This forage need only supply little more than maintenance ration, but because of low forage production on these areas and generally low quality forage, these requirements often are not met.


Emergence And Survival Of Four Introduced Wheatgrasses As Influenced By Rate And Season Of Planting On Abandoned Farm Lands Of Utah, Donald N. Hyder May 1949

Emergence And Survival Of Four Introduced Wheatgrasses As Influenced By Rate And Season Of Planting On Abandoned Farm Lands Of Utah, Donald N. Hyder

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A great deal has been accomplished in developing methods of restoring abused lands through seeding, yet there is much to be desired in refinement of techniques and in substantiation of previous experimental results. Controversial opinions as to the best season of planting indicate that additional trials are needed. New species need to be introduced, developed, and proved. Methods are needed which lead to more efficient utilization of those factors limiting the degree of success in establishment. Since moisture is the most predominant limiting factor throughout the arid and semi-arid range land, special attention is given to more efficient utilization of …

An Evaluation Of Trout Stocking In The Logan River Drainage, Nels Andrew Thoreson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

One of the more important forms of recreation in Utah is fishing. Each year since the end of World War II more than 100,000 resident and 4,000 non-resident fishermen have taken to the streams and lakes of this state. They spend approximately $2,200,000 each year in the quest of fish, mostly trout. In 1916, 25,473 licenses were sold, in 1937 the number of licenses had risen to 41,200, in 1945 the sales amounted to 104,000 and in 1947 had increased to nearly 131,000. Because of the increased number of fishermen each year, the desirability of greater numbers of legal-sized fish …


The Effect Of Time, Quantity, And Kind Of Irrigation On The Yield Of Sugar Beets, Delos Boyd Archibald May 1949

The Effect Of Time, Quantity, And Kind Of Irrigation On The Yield Of Sugar Beets, Delos Boyd Archibald

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Investigations on factors affecting yield of sugar beets during the past two years at Newton and Garland, Utah, have shown two outstanding facts about irrigating sugar beets. First, the amount of water applied may not be as important as the time at which they receive it. Second, sugar beets should not be made to suffer for water in the early part of their growing season.

These observations suggest the need for further studies on method, time and quantity of irrigation. Further information on the most economical use of irrigation water for sugar beets would be of great value to the …


The Comparative Value Of Commercial Phosphoric Acid As A Fertilizer, Bruce L. Baird May 1949

The Comparative Value Of Commercial Phosphoric Acid As A Fertilizer, Bruce L. Baird

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The practice of applying fertilizers to the soil by adding the liquid form to the irrigation water is increasing in popularity. There are several advantages maintained for such a method of application. Some of the advantages are:

(A) Ease of application.

(B) No special equipment is required for application.

(C) The fertilizer can be applied at any stage of plant growth without physical disturbance of the plant.

(D) Penetration into the root zone may be greater than the dry fertilizers.

Considerable phosphate fertilizer is used on soils of irrigated regions. If the behavior of liquid phosphoric acid after its incorporation …

Note On The "Leopoldina," Or "The Imperial German Academy Of Naturalists At Halle", S. W. Geiser Apr 1949

Note On The "Leopoldina," Or "The Imperial German Academy Of Naturalists At Halle", S. W. Geiser

Field and Laboratory

Recently, a professor of entomology sent an urgent letter of inquiry relative to the association of German naturalists called, in the older writings, the "Leopoldina," or, more fully, the "Academia Caesarea Leopoldino-Carolina Naturae Curiosorum." He had read an account of Jacob Boll, early Texan naturalist, and therein had noted his election (March 1, 1873) to membership in the society. The article stated that, in 1873, the Academy had its seat at Dresden, where its Praeses, Heinrich Gottlieb Ludwig Reichenbach had been for many years professor of natural history, and director of the natural history museum. It also stated, mistakenly, that …

Early Plant Collections Return To Texas, Lloyd H. Shinners Apr 1949

Early Plant Collections Return To Texas, Lloyd H. Shinners

Field and Laboratory

A herbarium is the means by which the plant life of a large area is sampled and made conveniently accessible for study. Texas, with the largest area and one of the most varied floras of the United States, is botanically one of the most poorly known. Although its botanical exploration has been going on for more than a hundred and twenty-five years (it began in the summer of 1820, when Edwin James, surgeon of Major Long's expedition to the Rocky Mountains, collected a few plants along the Canadian River in the Texas Panhandle), the early collections were sent elsewhere, and …

4-H Club : Clothing Project "A" Plan, Anna Walker

SDSU Extension Circulars

Have you ever been unhappy and probably disagreeable because you couldn't have a certain dress, shoes or hat that you thought you just had to have? Most girls, and sometimes grown people, at one time or another have felt this way. Usually these girls would not have felt unhappy about being unable to have a certain dress if they had made a study of their clothing expenditures and had spent their money wisely.


An Additional Trematode From Tortugas, Florida, And A New Name For Opisthoporus Manter, 1947, Preoccupied, Harold W. Manter Mar 1949

An Additional Trematode From Tortugas, Florida, And A New Name For Opisthoporus Manter, 1947, Preoccupied, Harold W. Manter

Harold W. Manter Laboratory of Parasitology: Library Materials

Professor José M. Ruiz of Sao Paulo, Brazil, has kindly called my attention to the fact that the generic name Opisthoporus Manter, 1947 had been used several times previously, a condition which I had indeed checked but thoughtlessly forgot. For Opisthoporus Manter, 1947 (nec Opisthoporus Benson, 1851; Opisthoporus Minot, 1877; Opisthoporus Fukui, 1929), the name Postporus is proposed. The two species become Postporus epinepheli (Manter, 1947) and Postporus mycteropercae (Manter, 1947).

The combination Pleurogonus candidulus (Linton, 1910) (misspelled "candibulus" in my paper) had been made in 1946 by Ruiz (1946: 295) where, however, it was first printed " …

The living room should be so planned and arranged that all members of the family enjoy it. This room should be comfortable, convenient, and pleasant. It should provide space for the interests of each member and it should express a spirit of welcome to guests. After a family planning session you'll probably find that your family wants the living room to include a reading unit, a conversation unit, a writing unit, a sewing unit and possibly a music unit.


Notes On Texas Compositae-I, Lloyd H. Shinners Jan 1949

Notes On Texas Compositae-I, Lloyd H. Shinners

Field and Laboratory

In the introduction to the unabridged edition of his Study of History (1933), Toynbee comments on the invasion of the field of scientific investigation by the Industrial System: the working up of raw materials ("data") by many individual workers ("scientists") into finished products ("papers," or as so commonly designated, "the literature"), according to more or less standardized methods of mass production ("Research"). Toynbee leaves it an open question whether this is not after all the best manner in which scientific investigation should be conducted in the present stage of development of western science. Certainly the magnitude of the task makes …
