Stomach Capacity, Digestion Rate, And 24-Hour Consumption Rate For The Bear Lake Sculpin (Cottus Extensus), Joseph H. Williamson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A curvilinear regression model was used to determine an expected stomach capacity for any size Bear Lake sculpin with a standard length between 4-9.5 centimeters. Stomach contents were then expressed as a percent fullness and the change in percent fullness with time intervals was used to compute an instantaneous digestion rate. The instantaneous consumption rate was computed by the formula C=log P₁ - log P₀ +d, where C = instantaneous consumption rate. The amount of food consumed during a time interval was computed from the formula I_t=C_tS_t, where I_t=amount of …

The Role Of Stomata In Gaseous Fluoride Injury To Plants And Several Enzymatic Changes Associated With That Injury, Bachettira Wthappa Poovaiah

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The effect of fluoride fumigation on water relations and several enzymes of Glycine max and Pelargonium zonale plants were studied.

Glycine Max leaves absorbed 600 parts per million fluoride from an atmosphere of 15 parts per billion fluoride during 96 hours fumigation. Lower, fully expanded leaves were always more severely damaged than the upper younger leaves. In day versus night fumigation experiments, although daytime fumigated plants absorbed less fluoride than continuously fumigated plants, they had two to three times more fluoride than the nighttime fumigated ones and also exhibited more severe damage.

Transpiration of fumigated plants decreased markedly, presumably due …

A Method For Plotting Isohyetal Maps Using An Analog Computer, Maurice George Kirwan

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The ability of the analog computer to stimulate physical phenomena is used in conjunction with a resistance paper model of the Walnut Gulch watershed in Arizona to plot constant precipitation maps from data obtained from recorded rainfall. Voltages which are proportional to rainfall at a specific raingage, located at scaled points of the resistance paper model, set up an electric field on the resistive sheet which is detected and processed by the computer. The detected potential is compared to a reference potential, or "precipitation value", and the necessary analog networks allow plotting of the equipotential line which is directly analogous …

Implications Of Tort Liability In Utah And Physical Educators Understanding Of Their Liability, Eldon C. Louder

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The Utah Tort Liability law was defined and a teacher understanding of the law and their liability was determined.

Physical Education teachers do not have a good knowledge of the state's liability law, nor are they aware of the liability they are open to.

Where opportunity was afforded, teachers were anxious to place the responsibility for their actions on someone of a higher position. This could be attributed to the fact that district and state administrators have not made an awareness of our new law.

The area of liability least understood is inadequate use of professional knowledge and skills. Sending …
