Effects Of Self-Pollination In The Genus Pinus, Liz Cole

Undergraduate Honors Capstone Projects

The problems of self-pollination among trees are a major concern to foresters. Silvicultural practices have an effect on the frequency of self-pollination.For example, a cut, such as a shelterwood or seed tree, reduces the number of individuals in the breeding population and increases the distance between individual trees. This tends to increase the frequency of self-pollination. These effects can either be helpful or harmful depending on the goals of the forester. Therefore, a basic understanding as to the effects of self-pollination on trees is necessary. The point of focus in this paper is the genus, Pinus.

Self-pollination occurs naturally in …

Huntington Lake Recreation Management Composite Plan, Kermit L. Johansson

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

The existing uses at Huntington Lake have evolved from development of the basin area for timber and hydroelectric generation. As a result of the resource attraction in the 1920's, roads were constructed, allowing an influx of recreation visitors. The scenic beauty of the lake made it a popular area which promoted the formation of resorts and Forest Service recreational facilities. Special use permits for recreation summer homes were later granted by the Forest Service to allow utilization of the lake when relatively few people could make the arduous drive up the narrow mountain road.

An Agro-Sylvo-Pastoral Approach To Desertification Control And Increased Productivity Of The Sahel, Rober D. Kirmse

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

The southern arid fringe of the Sahara Desert, called the Sahel, is progressively becoming less productive through a systematic deterioration of the environment. Population increases and technological advances have encouraged ecological degradation through man's normal activities for survival. The degradation process has been referred to as desertification, desertization, desert encroachment, and desert creep.

A Survey Of Selected Employers And Placement Counselors To Determine Sociocultural Factors In The Work Adjustment Of Navajo Students In Box Elder County, Utah, Dolores M. Keller

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

The primary goal of vocational education is to prepare the student to successfully enter the world of work. While the present educational structure seems to work well for most Anglo-American students, there is evidence that the system is not effective with minority students. For example , in the case of Navajo students in government-sponsored technical schools, the dropout rate (60 percent) suggests that for Native American students there are serious problems in the educational process which need to be investigated and understood.

Because of the sharply different cultural background of the Navajo student a formidable barrier frequently exists between student …

Characteristics And Genesis Of Some Soils Of The Upper Terraces Of Lake Bonneville, Mohammad Ali Haji Mirsadeghi

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The genesis and characteristics of the Timpanogos, Hillfield, and Sterling soils and an unnamed Mollisol (soil formed on north-slope) on the east part of Cache Valley were studied in order to determine (1) why the soil morphology is not chronologically related to the geomorphic surface and (2) why different soils have developed on these surfaces, even though the soil forming factors appear similar.

The particle size distribution of the upper horizons of the Timpanogos, Hillfield, and unnamed Mollisol pedons are relatively similar. These soils developed from stratified deposits with granulimetric composition in which 75 to 90 percent of the grains …

Economic Impacts Of Irrigation Technologies In The Sevier River Basin, Theodore R. Frickel

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The economic well-being of the semi-arid intermountain area requires efficient use of available water supplies. Agriculture, the major water-consuming industry, depends on irrigation water. The adoption of sprinkler systems that increase irrigation "efficiencies" and increase water available for irrigation upstream may interfere with the "tenure" of downstream water rights. The farmers would like to use the water saved to irrigate additional acreages or crop to provide greater profits.

The problem in letting farmers expand their irrigated acreage is that the individual farmer increases his profits through increased consumptive use. The consequent reduction in return flows reduces the water available to …

Recital Report, Gregory John Wheeler

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

Two basic ideas underlie the purpose of this recital and report:

(1) There are certain fundamental techniques that a woodwind teacher must employ in his teaching methods. These techniques include: tone production, fingerlings, and articulation, which vary significantly with each of the woodwind instruments. There are many teachers in the field of music education who profess to be skilled on all woodwind instruments, when in fact, their knowledge is limited to one instrument only. With this limited knowledge they attempt to teach techniques and concepts that pertain to all woodwind instruments. Indeed, an educator may have or create many problems …

Migrant-Nonmigrant Differentials, Housing Type, Community Satisfaction And Migration: A Study Of Nonmetropolitan Communities In Utah Within The Context Of Population Turnaround, Stephen Hua-Wah Kan

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Three major socio-demographic aspects of community life were examined in nonmetropolitan Utah within the context of the post 1970's population turnaround. They are: differentials by migrant status and housing type, patterns of community satisfaction, and migration expectations and migration.

Findings indicate that groups of residents with different migrant status and/or housing type have unique patterns in socio-economic status, social integration and community attachment, and potential contributions to the community. It was argued that these phenomena can be largely explained by the exchange theory.

With respect to the pattern of community satisfaction, it was found that the mobile home dwellers' level …

Microstructure And Rheology Of Process Cheese, Abdelaziz Hassan Rayan

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Four batches of pasteurized process cheese were prepared from the same Cheddar cheese by cooking to 82C in the presence of sodium citrate, disodium phosphate, tetrasodium pyrophosphate or sodium aluminum phosphate. Each batch contained the same moisture (40.6%) and emulsifying salt concentration (2.5%). The process cheese was sampled for microstructural and rheological examination after 0, 5, 10, 20 and 40 min in the cooker at 82C.

Even though each emulsifying salt affected the physical properties of the process cheese differently, the cheese generally became firmer, stiffer, more elastic and less meltable as cooking time increased from 0 to 40 min. …

Ultrastructural Localization Of Solanidine In Potato Tubers, Shau-Ron Han

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Solanine, the green substance in potato, Solanum tuberosum L., tubers, is a toxic glycoalkaloid that is a potential human health hazard. To control the formation of this glycoalkaloid a greater understanding of its site of synthesis is needed. Labelling of solanidine, a direct precursor in the biosynthesis of solanine, with digitonin may indirectly locate the site of solanine synthesis in tubers. A study using ultrastructural cytochemical techniques was initiated to explore this possibility.

Sprouted tips and peridermal complex (periderm and cortex) tissue were fixed three different ways: (1) glutaraldehyde only, (2) osmium tetroxide and glutaraldehyde, and (3) glutaraldehyde-osmium tetroxide-digitonin mixture. …
