This study was devised to determine the readiness of preschool children to learn about basic concepts of nutrition. Sixty preschool children enrolled in the Utah State University Child Development Laboratory, comprised the sample. Twenty children were taught at home by parents, 20 were taught at the Laboratory, and 20 received no instruction. The curriculum was based on the concept of nutrient density and used the Index of Nutritional Quality (INQ) in developing instructional mate rials. INQ is an index for comparing the amount of nutrients to the amount of calories in a food. Food Profile Cards, visual representations of this …

An Investigation Of Salinity Fluctuations In Soils Of A Northern Utah Marshland, Gary Roy Newman

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Ogden Bay Waterfowl Management Area is one of many marshlands bordering the Great Salt Lake that are extremely important as breeding habitats for North American waterfowl. Salinity, both of surface and interstitial waters, is an important factor in maintaining a suitable habitat within the marsh. For this reason, a study was undertaken to determine the factors affecting the salinity of surface and interstitial waters. A small (approx. 100 acre) subunit was studied extensively to determine; 1) variations in surface water salinity with flowrate and water level; and 2) variation in interstitial water salinity with depth and location within the subunit. …

The results of the tests gave …

Input Substitution In The Coal-Fired Electric Power Industry, Mohammad Fatoorehchie

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A gradual increase in the price of oil, a decline in the supply of gas, and a lag in nuclear construction leaves coal (a potential major resource for the future energy needs) as a fuel in ample supply. The major portion of the United States' electricity is generated by steam-driven generators where steam is produced by fossil fuel-fired boilers. In 1978, 47 percent of the total electricity generation was fueled by coal, up from 43 percent in 1975. Use of coal in generation of electricity has spawned numerous research projects concerning the economics of the coal-fired electric power industry.

Selected Projects In Costume Design, Michael Eagan

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

In his play Picnic, William Inge has created a study in male and female roles--or rather, the roles and types which society forces on them, and which they more frequently force on themselves. The people in this play are not conscious of their roles as roles. There is no free spirit portrayed in the attempt to throw off his or her classification. Even Madge, with her dreams of escape from the confines of small-town life, is acting in accordance with the behavior patterns of her particular genus. This play does not attack the male and female character typing which …

Diffuse Irradiance In The Rocky Mountains At 40° Latitude, Brock Allen Lebaron

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A study of the parameters effecting diffuse irradiance in mountainous terrain was made. Ground/location parameters of site elevation, ground albedo, elevated horizon and surface tilt were examined under the pertinent atmospheric conditions of clear, polluted, overcast, and cloudy. Measured diffuse irradiance data used for comparisons were taken from fall 1977-spring 1979 at four sites located in northern Utah.

Diffuse irradiance varied with elevation according to the existing atmospheric conditions. For clear sky, diffuse irradiance decreased with elevation due to the shorter optical pathlength, thus less scatter of the direct beam. However, with completely overcast sky, diffuse irradiance increased with elevation. …

A Model For Predicting Lightning-Fire Ignition In Wildland Fuels, United States Department Of Agriculture, Forest Service

Wildfires

A model has been developed for predicting the number of lightning-fire ignitions in wildland fuels. The model is based on both stochastic and physical processes. Stochastic methods are used to generalize the lightning storm characteristics and site conditions that affect the potential for ignition. Physical processes are involved in determining the ignition probability of woody fuels by individual lightning events. Input required to operate the model includes lightning activity, upper air windspeed (storm movement), fuel moisture, and fuel bulk density. The model can be used either to predict ignitions at some future time by using forecast data or to estimate …

Effect Of Displaced Geomagnetic And Geographic Poles On High-Latitude Plasma Convection And Ionospheric Depletions, Jan Josef Sojka, W. J. Raitt, Robert W. Schunk

All Physics Faculty Publications

We assumed that the ionospheric plasma at high latitudes has a tendency to corotate about the geographic pole and that magnetospheric convection is relative to the geomagnetic pole. With this assumption we calculated plasma drift patterns over the polar cap for a range of constant magnetospheric electric fields as well as for asymmetric electric fields with enhanced plasma flow on either the dawnside or the duskside of the polar cap. We calculated the drift patterns in both the geographic inertial and the geomagnetic inertial frame taking into account the displacement between the geographic and geomagnetic poles. We found that this …

Random Differential Equations In Water Quality Modeling, Brad A. Finney, David S. Bowles, Michael P. Windham

Reports

A probabilistic river water quality model is developed with the capability of determinging the joint and marginal probability density function of biochemical oxygen demand (BOD) and dissolved oxygen (DO) at any point in a river. The one dimensional steady-state model can be applied to a river system with any reasonable number of point loads and diversions and lateral surface and subsurface inflow. The model can simultaneously consider randomness in the intital conditions, inputs, and coefficients of the water quality equations. Any empirical or known distribution can be used for the initial condition. The randomness in the water quality equation inputs …

Modeling The Performance Of The Intermittent Sand Filter, P. A. Cowan, E. J. Middlebrooks

Reports

Several models were developed to predict the efficiency of the intermittent sand filter (ISF) in removing algae from wastewater stabilization pond effluent; volatile suspended solids (VSS) was the analytical technique used to identify algal concentrations. The first (ISF model) and second (modified ISF model) models consisted of two distinct portions: a surface algal layer (SAL) component and a sand phase component. In the ISF model, the sand phase component was described in terms of 20 empirical sand filter efficiency terms (20 ^ coefficients); in the modified ISF model, a functional relationship between ^ and filter depth was developed. The modified …
