Body Size, Body Composition, And Behavior Of Juvenile Belding Ground Squirrels, Martin L. Morton, Catherine S. Maxwell, Charles E. Wade Jun 1974

Body Size, Body Composition, And Behavior Of Juvenile Belding Ground Squirrels, Martin L. Morton, Catherine S. Maxwell, Charles E. Wade

Great Basin Naturalist

Juvenile Belding ground squirrels were studied in the Sierra Nevada. Females were more trappable, had smaller home ranges, and tended to enter hibernation earlier than males. The primary sex ratio was 1:1. Individuals first emerged from the natal burrow at three to four weeks of age and a body weight of 35 g. Body weight and linear dimensions increased thereafter until hibernation began. Maximum prehibernatory weight of 200 to 260 g was attained at about 12 weeks of age. Prehibernatory fattening began at about six weeks of age. Maximum lipid stores attained weighed about 80 percent of the lean, dry …

The Solution Photochemistry Of Benzaldehyde In Benzene, Ethanol, And 1-Hexyne, Ronald Douglas Knudsen Apr 1974

The Solution Photochemistry Of Benzaldehyde In Benzene, Ethanol, And 1-Hexyne, Ronald Douglas Knudsen

Theses and Dissertations

The photoreactions of benzaldehyde in benzene, ethanol, and 1-hexyne have been studied. Irradiation of benzaldehyde in benzene produces benzoin (I), hydrobenzoin (II), and deoxybenzoin (III). Irradiation of benzoin (I) in this solvent results in benzaldehyde formation as well as small amounts of (II) and (III). The ethanol irradiation of benzaldehyde resulted, predominantly, in the formation of (II) with (I) formed in small amounts. The photolysis of benzaldehyde in 1-hexyne produces (I), (II), (III) cis-2-heptenophenone (VII), trans-2-heptenophenone (VIII), heptanophenone (IX), and 2-(n-butyl)- 1,4-diphenyl-1,4-butanedione (X). Mechanistic pathways for the formation of these photoproducts are discussed. Separation and characterization of cis- and trans-2- …

Light And Electron Microscopy Of Resistant And Susceptible Alfalfa Roots Infected By Meloidogyne Hapla, Bernard Al Tait Apr 1974

Light And Electron Microscopy Of Resistant And Susceptible Alfalfa Roots Infected By Meloidogyne Hapla, Bernard Al Tait

Theses and Dissertations

Resistant (65-410 and 65-393) and susceptible (breeders Lahontan) alfalfa seedlings were infected with the Northern root-knot nematode, Meloidogyne hapla. Infected roots were fixed, stained, and embedded in plastic for ultrastructural investigations. Sections of plastic embedded tissue, cut at 0.5-1.5 microns for light microscopy investigations, were stained with various histochemical stains to determine the chemical composition of the nematode-altered tissues. In the susceptible cultivar, giant cells were formed by enlargement of nematode-stimulated cells without cell wall lysis. The giant cells became multinucleate by karyonkinesis without cytokinesis. Proplastids in the giant cells became structurally altered to form tubular complexes. The resistant plants …

A Calorimetric Study Of Metal Binding In Carboxypeptidase, Carbonic Anhydrase And Concanavalin A, Gary E. Hatch Apr 1974

A Calorimetric Study Of Metal Binding In Carboxypeptidase, Carbonic Anhydrase And Concanavalin A, Gary E. Hatch

Theses and Dissertations

The purpose of this study was to perfect a new calorimetric method for identifying and counting ionizable chemical groups on proteins. To do this, calorimetric and electrometric titrations were performed (using HCl and NaOH as titrant) on native carboxypeptidase, carbonic anhydrase and concanavalin A plus their apo and organic ligand bound derivatives. Readily identifiable endpoints were seen in the calorimetric titrations and general agreement was found between ΔH values obtained in this study and literature ΔH values of model compounds undergoing the same reaction. Imidazole groups were those most easily counted. Many assumptions had to be made, however, in concluding …

Pathological Changes In Tissues Collected From Kangaroo Rats At The Nevada Test Site, Michael Scott Fisher Apr 1974

Pathological Changes In Tissues Collected From Kangaroo Rats At The Nevada Test Site, Michael Scott Fisher

Theses and Dissertations

Structural aberrations induced in chromosomes by irradiation have been described and classified in great detail (Bender, 1969; Arena, 1971). According to Bender (1969), these aberrations appear after exposure to ionizing irradiation following cell division, or persist unmodified and unrecognizable in interphase cells for many years. In either case, these aberrations persist and can be seen years after radiation exposure.

Book Review: La Genese De Nova Friburgo. Emigration Et Colonisation Suisse Au Bresil 1817-1827, Leo Schelbert

Swiss American Historical Society Newsletter

Nicoulin's work on the making of Nova Friburgo is a thoroughly researched and well-presented study, but somewhat limited in its interpretive dimensions. Manuscript materials in Swiss federal, state, and village archives have been extensively consulted as well as archives in Rio de Janeiro and in Nova Friburgo. The author has furthermore perused a great many printed sources all of which enabled him to reconstruct the story of an emigration which in 1819 involved over 2000 Swiss and had the active support of Swiss governments as well as of Brazilian authorities. A 70-page appendix offers the reader a useful sample of …

The Settlement Of Teton Valley, Idaho-Wyoming, David Brooks Green Jan 1974

The Settlement Of Teton Valley, Idaho-Wyoming, David Brooks Green

Theses and Dissertations

Teton Valley, throughout many centuries, has attracted several occupance groups, each interacting with the environment in various ways for various reasons. Indian and explorer contact did little to alter the surroundings. More frequent contact came, however, as trappers and traders visited the valley to trap beaver and meet in rendezvous.

The end of intensified fur trapping slowed contact with the basin. Government personnel, a painter, a few squawmen and horse thieves were the only inhabitants because Indians, remoteness, and harsh climatic conditions kept others out until 1882 when permanent agricultural settlers entered the valley. Hundreds of people followed, many of …

Perception And Land Use: The Case Of The Mormon Culture Region, Lester D. Campbell Jan 1974

Perception And Land Use: The Case Of The Mormon Culture Region, Lester D. Campbell

Theses and Dissertations

Since the first man perceived and used his environment, there has existed a reciprocal man-land relationship. The physical environment provides opportunities for man's use and also sets limitations. Man's perception and use of his environment is greatly influenced by his culture, which consists of past experience, technology, attitudes, and needs. It is these factors that determine what a man will see as possibilities in land use, and how he will use his environment.

In the case of the relic Mormon Culture Region, Mormon religious beliefs highly influenced perception of the environment. Most visual geographical features of the landscape in the …
