Co-Digestion Of Cattle Manure And Cheese Whey For Biogas Production And Characterization Of Biomass Effluent, Dillon Fallon

All Graduate Theses and Dissertations

The Western Dairy Center at Utah State University had recognized through traiing of cheesemaking that a challenge that can exist for farmstead and artisan cheese manufacturing operations is disposal or utilization of the whey that is produced when milk is converted into cheese. Land application of whey is limited and can cause odor problems which would be detrimental to a cheesemaking operation located at the rual-urban interface.

The project provided information in support of a research grant from the Western Sustainable Agribulture Research and Education program that was investigating economics and feasiblity of using anaerobic digestion for treatment of whey ...

Sociodemographic And Climatic Factors Shaping The Development Of Drought Policies In Major U.S. Cities, Riana S. Gayle

All Graduate Theses and Dissertations

In most parts of the world, drought is an inevitable and natural occurrence. However, as the climate continues to warm, and populations grow and expand, the negative impacts of this extreme weather event are predicted to become more pronounced. This leads many communities and stakeholders to question what is being done to prepare society for widespread drought? The following research determines different social and atmospheric characteristics that affect a city’s likelihood of having a drought policy in place.To do this, a thorough search was conducted at the city level to determine where drought policies are currently located in ...


Evaluation Of Antioxidant Properties Of Native Utah Berries And Their Potential For Use In Meats, Xiaoxi Wang 2018 Utah State University

Evaluation Of Antioxidant Properties Of Native Utah Berries And Their Potential For Use In Meats, Xiaoxi Wang

All Graduate Theses and Dissertations

In industry, antioxidants are added to prevent changes that affect quality due to oxidation, such as the development of off flavors, unacceptable odors and discoloration. New resources that are familiar to consumers and may work as antioxidants should be studied.

The changes in antioxidant activity were determined for four freeze-dried native wild berry powder species in Utah, including skunkbush (Rhus trilobata), chokecherry (Prunus virginiana), river hawthorn (Crataegus douglasii) and silver buffaloberry (Shepherdia argentea), during cold storage (-20 °C) for 6 months. The total antioxidant activity was stable in most of the berry powders during the six months of frozen storage ...

Patterns Of Use Before And After A Labeling Intervention Among Collegiate Division I Athletes At A Fueling Station, Julie A. Buzzard

All Graduate Theses and Dissertations

The Fueling Station at Utah State University was created to provide pre-workout fueling and post-workout recovery foods to the Utah State University athletes. The athletes use an online survey to mark what foods they selected after each visit to the Fueling Station.

There is a large amount of research on the lack of sports nutrition knowledge in collegiate athletes, but there is little information on the dietary intake of athletes, the education of athletes, and the education of macronutrient timing in athletes.

A food labeling system named “Gain Your Edge” food labels that targeted the education of timing was created ...


Plant Evolutionary Response To Climate Change: Detecting Adaptation Across Experimental And Natural Precipitation Gradients, Jacqueline J. Peña 2018 Utah State University

Plant Evolutionary Response To Climate Change: Detecting Adaptation Across Experimental And Natural Precipitation Gradients, Jacqueline J. Peña

All Graduate Theses and Dissertations

Global climate change is a real-time problem that presents threats to many species. Climate change can alter ecosystems and may lead to species extinction. Species can respond to climate change by moving to a better environment or adapting. Therefore, it is necessary to rely on several approaches and perspectives to anticipate ecological impacts of climate change. A common strategy uses models to understand how populations respond to different climate scenarios. Ecological models have helped usunderstand population persistence, but they often ignore how populations adapt to environmental stress. Adaptive evolution has been ignored because it was assumed that evolution was too ...


Organic Matter Sources, Composition, And Quality In Rivers And Experimental Streams, Julia E. Kelso 2018 Utah State University

Organic Matter Sources, Composition, And Quality In Rivers And Experimental Streams, Julia E. Kelso

All Graduate Theses and Dissertations

Organic matter (OM) is often considered the “currency” for ecosystem processes, such as respiration and primary production. OM in aquatic ecosystems is derived from multiple sources, and is a complex mixture of thousands of different chemical constituents. Therefore, it is difficult to identify all the sources of OM that enter and exit aquatic ecosystems. As humans develop undisturbed land, the rate at which terrestrial OM (e.g.soil and plants) and associated nutrients (e.g.nitrogen) enters rivers has increased. Increased nutrients may lead to increased primary production from aquatic plants and algae, potentially causing eutrophication and harmful algal blooms ...


Assessing The Ecological Implications Of The Altered Flow And Sediment Regimes Of The Rio Grande Along The West Texas-Mexico Border, Demitra E. Blythe 2018 Utah State University

Assessing The Ecological Implications Of The Altered Flow And Sediment Regimes Of The Rio Grande Along The West Texas-Mexico Border, Demitra E. Blythe

All Graduate Theses and Dissertations

Large, exotic (those whose headwaters are in distant places) rivers are some of the most unique and diverse ecosystems on earth. Because they often flow through a multitude of biomes and climates, their waters are a vital resource not only for the organisms that inhabit these rivers, but for human societies as well. Thus, large rivers, like the Rio Grande, that flow through arid and agricultural regions are highly regulated and diverted. Regulation and dewatering upset a river’s natural flow regime (e.g., magnitude, duration, timing of large flood events), subsequently impacting the river’s ability to transport its ...


Synthesis Of Dicamba Glucosides For The Study Of Environmental Dicamba Drift Effects On Soybeans, Holly Wallace 2018 University of Arkansas, Fayetteville

Synthesis Of Dicamba Glucosides For The Study Of Environmental Dicamba Drift Effects On Soybeans, Holly Wallace

Theses and Dissertations

The most popular herbicide used for weed control has been glyphosate for many years in the Midwestern United States. Plants have begun to develop a resistance to glyphosate due to over use of the herbicide. This herbicide resistance has pushed farmers to turn to alternative herbicides such as dicamba and 2,4-D. Recently agrochemical companies have developed genetically modified crops that are resistant to herbicides such as dicamba. These modified crops allow farmers to spray their fields with dicamba without fear of crop damage. Farmers of non-genetically modified crops, however, suffer damage and loss of yield from herbicide drift effects ...

Identifying And Assessing Conflicts Between Future Development And Current Migratory Bird Habitat Around Farmington Bay, Utah, Aubin A. Douglas

All Graduate Plan B and other Reports

Every year, the Great Salt Lake (GSL) and its associated wetlands provide critical habitat for over 250 migratory bird species from both the Pacific and Central Flyways. The GSL borders the Wasatch Front, which is the fastest growing and most populous region in Utah. To support the ever-increasing working population, the government of Utah aspires to increase the robust economic growth of the region through economic incentives and development of infrastructure. As this area continues to develop, greater pressure will be placed on the surrounding natural resources, including the GSL, its wetlands, and the open space and agricultural land that ...


Identification Of Sperm Chromatin Proteins As Candidate Markers Of Stallion Fertility, Chelsea C. Ketchum 2018 Utah State University

Identification Of Sperm Chromatin Proteins As Candidate Markers Of Stallion Fertility, Chelsea C. Ketchum

All Graduate Theses and Dissertations

During spermatogenesis, histones are largely replaced by transition proteins and protamines in normal stallions. Incomplete nucleoprotein exchange results in the abnormal retention of histones and transition proteins, which is an indicator of poor sperm quality. Equine nucleoprotein exchange has not previously been investigated in detail, so that equine sperm chromatin quality problems, which are often responsible for poor breeding performance of stallions, are not well understood. In order to characterize chromatin remodeling events in stallion spermatogenesis and to identify proteins indicative of sperm chromatin defects, such as excessive amounts of histones, we identified antibodies that recognize equine testis-specific proteins of ...


Interactions Between Biochar And Compost In Organic Winter Wheat Production And Soil Quality Under Dryland Conditions, Phearen Kit Miller 2018 Utah State University

Interactions Between Biochar And Compost In Organic Winter Wheat Production And Soil Quality Under Dryland Conditions, Phearen Kit Miller

All Graduate Theses and Dissertations

Organic wheat grown under dryland conditions encounters challenges such as limited nutrients and water. Maintaining organic wheat production requires solutions to these problems in order to retain economic sustainability for the farmers.

Research on biochar and compost have been conducted globally. Despite well known benefits of compost on soil and crop production, few organic farmers apply compost to their fields. Research on biochar is still new. Biochar is charcoal created from pyrolyzing agricultural material under conditions of low oxygen and high heat. Many studies claim that biochar is a valuable soil amendment for improving organic production and reducing environmental pollution ...


An Evaluation Of Bull Trout Movement Dynamics In The Walla Walla River, Courtney Newlon 2018 Utah State University

An Evaluation Of Bull Trout Movement Dynamics In The Walla Walla River, Courtney Newlon

All Graduate Theses and Dissertations

Bull trout are a fish species listed as threatened under the Endangered Species Act.Historically, they ranged from Northern California at the southernmost extent, into Canada at the northern most extent, and east into Nevada and Montana. Bull trout are highly migratory and require large, unfragmented habitats to persist and are thus highly susceptible to human induced land-use practices. The goal of my thesis was to obtain a better understanding of bull trout movement patterns in the Walla Walla River, Washington using complimentary techniques; Passive Integrated Transponder (PIT)technology and otolith microchemistry. PIT tags can be injected into a fish ...


The Study Of Alcoholic Liver Diseases, Seun Emmanuel Owoseni 2018 East Tennessee State University

The Study Of Alcoholic Liver Diseases, Seun Emmanuel Owoseni

Electronic Theses and Dissertations

Excessive alcohol consumption is the primary contributing factor in the development of alcoholic liver diseases (ALD). Nicotine contained in tobacco is a major addictive alkaloid, which enhances the effects of ALDs. The major enzyme involved in nicotine metabolism is cytochrome P450 2A5 (CYP2A5) which is produced in the liver. Alcohol can stimulate the CYP2A5 enzyme. We utilized cyp2a5-/- knockout mice in this research to examine the effects of CYP2A5.

The cyp2a5-/- mice and wild-type (WT) mice were fed liquid ethanol diet with or without nicotine to induce ALD. Nicotine enhancing effects on ALD were observed in WT mice but not ...


Prioritizing Chemical Constituents In Tobacco Products And Smoke To Predict Developmental Osteotoxicity In Human Embryonic Stem Cells, Joseph Madrid 2018 California State University, San Bernardino

Prioritizing Chemical Constituents In Tobacco Products And Smoke To Predict Developmental Osteotoxicity In Human Embryonic Stem Cells, Joseph Madrid

Electronic Theses, Projects, and Dissertations

Though it is well known that tobacco related products can cause prenatal maldevelopment, very little is known on how tobacco products affect bone tissue as it develops in the embryo. Identifying which chemicals can induce the greatest harm to the prenatal skeletal system is an improbable task as there are over 7,000 chemicals in tobacco smoke alone. We hypothesized that the Toxicological Priority Index (ToxPI) program can be used to rank osteogenic cytotoxicity potential to aid in the assessment of what chemicals out of the thousands can cause osteogenic differentiation inhibition. ToxPI aggregates information from various assays and incorporates ...

The Chocó-Darien Global Ecoregion (CGE) in South America is one of 25 global biodiversity hotspots prioritized for conservation. I performed the first land-use and land-cover (LULC) change analysis for the entire CGE in this dissertation. There were three main objectives: 1) Select the best available imagery to build annual land-use and land-cover maps from 2001 to 2015 across the CGE. 2) Model LULC across the CGE to assess forest change trends from 2002 to 2015 and identify the effect of proximate causes of deforestation and reforestation. 3) Estimate the effects of underlying drivers on deforestation and reforestation across the CGE ...


Fiscal Reform Scenarios And Accessibility 2018.08.20.Docx, Guillermo Fernandez 2018 Louisiana State University and Agricultural and Mechanical College

Fiscal Reform Scenarios And Accessibility 2018.08.20.Docx, Guillermo Fernandez

Guillermo Fernandez

Since signing the peace accords in 1996, the Guatemalan government committed to increase the tax burden of 1995 by 50% to a total of 13%. This target has only been reached 4 times in more than two decades. There have been multiple attempts at tax reforms that have failed or been incomplete. Guatemala exhibits much income inequality and is one of the poorest countries in the region.  
Given this background, the problem to be considered in this analysis is that there is little information regarding how different tax reforms would affect the accessibility to food in Guatemala. With information regarding ...

Novel Inactivation Of The Causative Fungus Of White Nose Syndrome With Methoxsalen And Ultraviolet A Light, Colin J. Hartman, Joseph Mester Phd, Alan Cohen Md

Posters-at-the-Capitol

White Nose Syndrome (WNS) is a newly recognized disease responsible for the rapid mass destruction of the North American bat populations. This study addressed the novel inactivation of fungal spores from Pseudogymnoascus destructans, the causative agent of WNS, using ultraviolet A (UVA) light at 365nm and methoxsalen, a photosensitizer from a family of compounds known as furanocoumarins. Penicillium crustosum, an environmental fungus, was studied as a comparator.

Spore suspensions were soaked in specific concentrations of methoxsalen and subsequently exposed to UVA light. The plates were examined for both spore inactivation and resultant inhibition of colony growth. The results demonstrated that ...
