Leaf Epidermal Transmittance Of Ultraviolet Radiation And Its Implication For Plant Sensitivity To Ultraviolet-Radiation Injury, Ronald Robberecht

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Leaf epidermal transmittance of ultraviolet radiation (280-400 nm) was examined in several plant species to determine the capability of the epidermis to attenuate solar ultraviolet radiation. Epidermal samples were mechanically isolated and examined with a spectroradiometer/integrating sphere for transmittance. A survey of 25 species exposed to natural insolation was conducted. Although the species differed in life form, habitat type, and epidermal characteristics, epidermal transmittance was generally less than 10%. Ultraviolet radiation was attenuated 95 to 99% in more than half of the species. In 16 species, flavonoid and related pigments in the epidermis accounted for 20 to 57% of the …

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

Shorthand plays a very necessary part in preparing our office education students. There has been much discussion as to which type of writing system is more efficient. Some authorities in the field fee l that abbreviated longhand systems can be learned more easily than symbol systems.

According to Wagoner:

The usual advantages claimed for various abbreviated longhand systems are: the ease of converting from longhand to an abbreviated longhand system, a shorter learning period than a symbol system, and the ease of transcription. (1960, p. 21)

Since the Forkner system is based largely on what the learner already knows, the …

Federal Reclamation In Utah To 1974, Glen Shagren

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

The Colorado River Basin of Utah covers approximately 49 percent of the state. A sizable snowfall, particularly in the Uintah Mountains, makes Utah's major contribution to the water flow of the Colorado River. During the spring runoff the melting snow finds its way to the Colorado River, which eventually empties into the Gulf of Mexico. In large measure this water has held, and still holds, the key to Utah's development.

Because Utah lies in an arid region, water is an extremely important resource. Upon arrival to the Great Basin in 1847, the Mormon pioneers immediately set about solving the problem …
