An Inheritance Study Of Sedimentation Values In Three Winter Wheat Crosses, Douglas J. Baker

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Three crosses were used to study the inheritance of the sedimentation properties in hard red winter wheat. The parents of the three crosses were the variety Delmar, and the breeding lines 217-61-7-14 and 217-19-5. Delmar has high sedimentation properties, 217-61-7-14 is intermediate, and 217-19-5 has very poor sedimentation qualities.

Sedimentation tests were run on five replications of the parents and 300 samples of the F₃ populations in each cross. A semi-micro sedimentation test (a one-fourth scale test) was run on 200 F₂ plants and the F₁'s from each cross. The distributions from each cross were analyzed …

Brisket Disease: Influence Of Hypoxia And An Induced Calcium-Potassium Imbalance On The Mineral Composition Of Blood, Heart, Liver, Kidney, And Bone, David Eugene Bailey

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Brisket disease, an affliction of cattle, is important because of: (1) economic losses, (2) similarities to chronic mountain sickness in humans, and (3) the provision of experimental animals for cardiac research. In afflicted cattle, right cardiac ventricular hypertrophy and dilatation occur and are manifestations of attempted compensation for reduced alveolar oxygen by increasing pulmonary circulation.

Geographic variations in occurrence of brisket disease in Utah indicate that hypoxia is not the sole causative factor. From the findings that afflicted cattle exhibit hypocalcemia and hyperkalemia, and the disease occurs most commonly in wet meadowland environments where potassium is high and calcium low …

Rates Of Algal Production And Sphaerotilus Assimilation In The Logan River, Utah, Gary D. Beers

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The rates of algal production and Sphaerotilus assimilation in the lower Logan River benthos were investigated in 1966 and 1967.

The rate of annual gross primary production (3,416 Kcal/m²/yr) was estimated from the relation of pigments to the photosynthetic rate of benthic communities in a submersible, metabolism chamber. The photosynthetic rate was predicted with high precision when a measure of the accessory pigments (D480/D665 and/or chlorophyll-c) was considered with the chlorophyll-a. The pigment density estimates were obtained from the community present on paraffin-coated, concrete hemispheres after immersion in the river for periods ranging from 11 to 20 …
