The Reaction Of Some Sodium Salts Of Fatty Acids And Benzoic Acid With Α-Bromobenzyl Cyanide, Richard W. Perkins

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Fife (4) and O'Shaughnessy (12) have made a series of di-esters by allowing the sodium salts of various fatty acids to react with ethyl monochloracetate according to the following equation:

RCO₂Na ≠ ClCH₂CO₂C₂H₅ ---------> RCO₂CH₂CO₂C₂H₅ ≠ NaCl .

The mechanism of the reaction appears to be ionic and to involve the attack of an RCO₂^- ion on the carbon atom to which the chlorine atom is attached. As the RCO₂^- approaches this carbon atom the chlorine atom moves …

Factors Affecting The California Quail Populations In Uintah County, Utah, R. Lynn Nielson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The California Quail is native to the coastal and semi-arid regions of California extending north into Oregon. Two subspecies are commonly recognized. the California Quail (Lophortyx californica brunnescens Ridgway), and the Valley Quail (Lophortyx californica californica Shaw). The two forms are very similar in coloration and habits and, for the purpose of this study, no effort is made to distinguish the two.

The Content Of Pantothenic Acid, Folic Acid And Vitamin B12 Like-Activity In Alfalfa Hay Grown In Utah Soils Treated With Different Fertilizers, Buranaphoka Kashemsri

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Vitamins play an important role in the nutrition of man and animal. As early as 1897 Eijkman was able to demonstrate the symptoms of thiamine deficiency disease in birds. Since then, vitamins have been regarded as one of the most essential factors in nutrition. Only small quantities in the diet are necessary, yet lack of any of them will inhibit the growth and produce certain kinds of deficiency diseases.

In the 1951 Encyclopedia Americana Annual is this report on the activities in applied mathematics for the previous year:

Progress was made on the general problem of finding the eigenvalues of matrices and systems of differential equations. Considerable effort was also …

Some Effects Of Fluctuating And Falling Water Levels On Waterfowl Production, Kenneth E. Wolf

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

There are today many areas and types of water storage. The uses to which these are put are many, and the prospect for the future can only be that there will be an increase in the number of these reservoirs. These areas are usually operated with regard only for power production, irrigation, or storage, but there is a growing concern about the effects on wildlife which this type of operation may have. Fluctuating water levels, and falling water levels are not restricted to man-made impoundments tut are characteristic of many of then. Biologists have observed that these variations in water …

The Freezing Point Of Water In Puddled And Unpuddled Soils At Different Soil Moisture Tension Values, Robert B. Campbell

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A technique that will adequately describe the physical condition of water in the soil has long been desired by scientists. The method should include the effect of soluble materials on the osmotic pressure of the soil solution, and also the effect of surface force action between the soil and soil water.

Parker (8) demonstrated that the freezing point was reduced in the presence of finely divided material. This suggested the possibility of using the cryoscopic procedure to measure the physical condition of water soil. More recently, the introduction of Thermistors for accurate temperature measurement have made it desirable to investigate …

Pellet Seeding On Sagebrush Range, Gordon E. Gatherum

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Seeding deteriorated range lands efficiently and economically has become one of the most promising means of improving the agricultural economy of the western range states. By providing the most rapid means of increasing the quantity and improving the quality of forage for livestock, and aiding in the prevention of soil erosion, artificial seeding contributes directly to the stability of agriculture.

Although many successful methods of artificial revegetation have been developed by experience and through research, there is still a great need for refinement in techniques to insure better overall success and greater economy of operation. Improper methods often result in …

The Logan River heads in the southeastern corner of Franklin County, Idaho, and runs in a south and westerly direction. It enters the state of Utah through the northern boundary in the northeast corner of Cache County. The main stream is fed by two tributary streams which head in separate directions a few miles apart. The Franklin Basin branch is the main contributing tributary while the Beaver Creek branch is nearly as large.

The Potash Status Of Utah Soils, Sukhendu Bikas Chaudhuri

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Potassium is one of the essential plant nutrient elements. It is used by plants in the synthesis and distribution of carbohydrates (25)² and in the formation of proteins and oils. Potassium also seems to exert many of its effects by influencing enzymatic activity in cells.

Potassium occurs as the monovalent cation on plant cells and undoubtedly exerts important effects upon such phnomona as the permiability of the cytoplasmic membranes and hydration of protoplasma. Plants assimilate potassium either from the soil solution or directly from the exchange complex.

The Effect Of Light, Soil Temperature, And Soil Moisture On High-Lime Chlorosis, Lauren M. Burtch

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Chlorosis of plants from a lack of available iron is one of the most common plant nutrient problems of the calcareous soils of the west. The disease is characterized by a yellowing of the plant leaves and is accompanied, in severe cases, by a partial root death and premature defoliation (3). In addition to reducing growth, the disease greatly reduces the quality and yield of plants.

Many types of plants are affected by iron chlorosis. In Hawaii and Porto Rico rice, sugar cane and pineapple are susceptible, while in California and Arizona, citrus trees are seriously affected. In Utah apples, …

Solubility And Physiological Availability Of Phosphates In Sodium And Calcium Systems, Parker F. Pratt

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

One of the principal fertility problems of calcareous soils is the lack of available phosphates. The factors which control this availability are not completely understood. One hindrance to the solution of the problems involved results from confusion of the concepts of solubility and availability. Availability is the net effect of the chemical state of a plant nutrient element and the ability of the plant to utilize the forms of the element present under the existing chemical and physical environmental conditions. In this paper, the term solubility will be used to designate the chemical solubility of an element in water or …

The Dry Lake Section Of The Brazer Foundation, James S. Yolton

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The Dry Lake section of the Brazer formation, totalling 3100 feet in thickness, is an excellent exposure containing an abundance of fossils many of which are well preserved. The fauna indicates that the formation is to be correlated with the Upper Iowan and Chester series of the type Mississippian system in the Mississippi Valley section. Substantial fossil evidence indicates the following correlation for the Brazer formation members. The C unit represents the western equivalent of the Middle Meramec group, i.e., the Salem and St. Louis limestones. The D member is decidedly Ste. Genevieve in general faunal aspects but, because of …

Phosphate Deposits In Western Summit, Wasatch, Salt Lake, Morgan, And Weber Counties, Utah, Alvin M. Hanson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Phosphate deposits in the western United States have been the subject of considerable discussion in the last decade, and during the last few years much interest has been aroused in them. Phosphate was first discovered in this area in 1889, but it was not until 1906 that the United States Government took active interest in the study of these deposits. The investigation by the government of the occurrence of western phosphate was begun by Weeks and Ferrier (10), and later carried on by others. On December 9, 1908 the western phosphate reserve was created and many acres of land were …

Cambrian Stratigraphy In The Northern Wasatch Region, George Burke Maxey

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

An exhaustive field study of the Cambrian stratigraphy of the northern Wasatch region indicates that in addition to the Blacksmith Fork section there are two complete and better exposed middle and upper sections. Several other good exposures of the lower Middle Cambrian section have been studied in detail. The Spence shale is found to be a member low in the Langston, not the basal member of the Ute. Relative ages of the Spence shale and Ptarmigania faunas have been determined. Other Cambrian faunal zones have been discovered and are discussed. Paleontologic evidence suggests that the Nounan formation is of Upper …

Zinc Relationships Of Some Utah Soils, Wilford Derby Laws Jr.

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Recent reports from many parts of the United States indicate that the so-called zinc-deficiency disease is wide spread. It affects some varieties of trees in some areas and all varieties in other areas, and occurs from Florida westward to the Pacific coast and northward to the Canadian line. Although the disease is more prevalent in trees, it is also known to affect annual plants.

A recent survey of Utah orchards shows a wide-spread occurrence of little-leaf, a zinc deficiency disease, in fruit trees. The disease was found to be common on the upper sandy soils between Ogden and Salt Lake …

Glaciation In The Logan Quadrangle, Utah, J. Llewellyn Young

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

That the higher valleys of the Wasatch Mountains were occupied by Pleistocene glaciers has long been known. King, Hague, and Emmons, geologists of the Fortieth Parallel Survey, the first to undertake a systematic study of any part of the Wasatch Mountains, recognized this fact and their report includes a map which shows in a rough way the extent of the glaciated areas in the Central Wasatch (11 ). In 1909 Atwood (1) made a detailed study of the glacial features of the Central Wasatch in connection with his study of glaciation in the Uinta Mountains. He mapped the deposits of …

A Study Of The Equilibria Between Bentonite And The Various Replacing Agents In Alcoholic And Water Solutions, Joel E. Fletcher

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Investigators in soils have long recognized the importance of the colloidal fraction of soil, and also the almost inseparable problem of replaceable bases. It is generally accepted that the replaceable base fraction of a colloid controls to a large degree the physical properties exhibited by it. Volumes of work have been written on the problem of controlling the reactions of this fraction and on studies of the properties exhibited by it when it is saturated with various cations. Each worker has proceeded in his own individual way or followed the example set by some previous worker with specific modifications.

The Vitamin D And Provitamin D Content Of Some Varieties Of Utah Wheat, Harold M. Nielsen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Cereal grains were known to be notably deficient in the anti-rachitic principle even before the discovery of vitamin D. Clinicians had associated a type of rickets of infancy, characterized by an over-weight, flabby, bowlegged condition, with a diet consisting mainly of cereals. Mellanby (1) in 1921 concluded that this type of rickets is induced by overfeeding with carbohydrates. He also showed in the same report, however, that oatmeal, although it contains less carbohydrates than the other grains tested, possesses a special tendency toward rachitogenesis.

The Geology Of A Part Of The Bear River Range And Some Relationships That It Bears With The Rest Of The Range, Vic E. Peterson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The structure of the western three or four miles of the Bear River range east of Logan, Utah, has many times been alluded to in papers written locally on Cache Valley and the related ranges. There has not however, ever been, to the author's knowledge, an investigation made of this portion of the range for the express purpose of determining its exact structure. Although the area specifically covered by this present investigation is greatly inadequate to base the whole west range structure on, the author believes that the facts brought to light by the specific study of this area, added …

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The establishment of the Bear River Bay Bird Refuge has created for the state of Utah an immense and valuable biological field, a veritable paradise for naturalist and sportsman alike. The naturalist wants a place to study wild life and the sportsman desires game. With the proper control of open seasons on wild fowl the hunting instinct and incentive for the sport should be satisfied for the sportsman. To the naturalist this region will open up bountiful treasures of knowledge that is to be gained only by intense and prolonged scientific study.

The Design Of A Multiple Intake Drainage Well, Orville L. Eliason

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The reclamation of water-logged land by suitable yet inexpensive forms of drainage is becoming a problem of constantly increasing magnitude. A fairly large portion of the extensive land areas, once considered as worthless has proved to be valuable by the introduction of proper drainage systems. Land areas, in which drainage in its simpler forms has proved inadequate, could perhaps be made valuable were it possible to develop an inexpensive yet effective form of drainage.

This paper has been prepared primarily for a consideration of poorly drained land areas and a possible means of their reclamation by a suitable choice and …

The Devonian Of The Bear River Range, Utah, I. Lavell Cooley

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The geological column in northern Utah has had very little detailed study. Those who have made reports on this section have done so only in a very general way, making no detailed sections of any part of the column, excepting that of the Cambrian made by Walcott.¹ Other work has been done by Mansfield² in southeastern Idaho and a general section of the Devonian made in Green Canyon, Bear River Range, Utah by Kindle.³

Due to the lack of any detailed work of this nature being done in the Bear River Range, suggested the matter of making …
