Manipulation Of The Spatial Grazing Behaviour Of Livestock In Extensive Grassland Systems, Derek W. Bailey, Mitch B. Stephenson, Milton G. Thomas, Juan F. Medrano, Gonzalo Rincon

IGC Proceedings (1997-2023)

Spatial behaviour of livestock is a critical factor in grassland management. Recent and ongoing research suggests that new approaches can be used to manipulate where cattle graze. The combination of strategic supplement placement and low-stress herding can be used to target cattle grazing and potentially may be useful for managing fine fuels. A phenotype to genotype association study of cattle spatial behavior suggests that use of rugged terrain and areas far from water is inherited. Although more research is needed, selection for animals specifically adapted for mountainous terrain or extensive paddocks may be an alternative for managing grasslands in the …

Status And Remediation Of Mercury In Fish And Aquatic Ecosystems, Geoffrey Dean Millard

Dissertations - ALL

Mercury is a known neurotoxin which can bioaccumulate and biomagnify as methylmercury, causing significant human and ecological impacts. New York State and the surrounding region is impacted by mercury in complex ways as some areas are recovering from the effects of acidic deposition while the entire region is increasingly influenced by climate change. In order to better understand the drivers and trends of mercury dynamics in New York State, my research was conducted in three phases: 1) the impact of lime (calcium carbonate) additions on mercury cycling in small acid-sensitive headwater streams of the Adirondack State Park; 2) applied advanced …

Determining Water Requirements In Turfgrass Systems, Tyler Quinn Carr

Graduate Theses and Dissertations

Turfgrass lawns are commonly utilized for home and commercial applications because of the aesthetic, environmental, and recreational benefits grasses provide, but many people perceive turfgrass as solely an aesthetic benefit that requires significant water inputs. It is important to identify and use turfgrass cultivars that have known drought tolerance, and also fine-tune and throughout development. A series of field experiments were conducted to determine the water requirements of turfgrass lawn systems with the following objectives: 1) investigate differences in chronic drought resistance and irrigation recommendations among cultivars of Kentucky bluegrass (Poa pratensis L.) and tall fescue (Festuca arundinacea Schreb.) 2) …

“An Aquatic Reverie” | Mallarmé’S Writing On Water And The Naming Of Waves, Clark Lunberry

English Faculty Research and Scholarship

At his home outside Paris, in Valvin, Stéphane Mallarmé spent much time on his small boat dreamily sailing upon the Seine, seeing this body of flowing water as a site for inspiration and inscription. Indeed, Mallarmé once confided to a friend, “I no longer write a poem without an aquatic reverie running through it,” and that, for him, poetry was like an “oar stroke,” and the sail, a “white page.” When Mallarmé was invited to lecture at Oxford University in 1894, he did not speak specifically of time spent on the water, his life on the Seine, but his own …

Biochar As A Means Of Water Purification In Haiti, Caolan Keenan

Honors Projects

Our research set out to determine if biochar, a compound made by burning organic plant matter in a low oxygen environment, would be a suitable means of removing E. coli populations from contaminated water collected from the Grand River in Allendale, MI using simple materials to construct a filter that could be constructed and used in Haiti. Previous research has shown biochar to be effective at trapping bacteria and other contaminants in the porous surface and by binding other non organic contaminants. We constructed multiple iterations of these filters using gravel, sand, and biochar and ran three live tests with …

Effects Of Changed Asian Water Tower On Tibetan Plateau Ecosystem: A Review, Di Yangping, Zhang Yangjian, Zeng Hui, Tang Ze

Bulletin of Chinese Academy of Sciences (Chinese Version)

As the "water tower" of Asia, the Tibetan Plateau provides basic water resources for the regional ecosystems. Among the variety of water resources, natural precipitation is most relevant to ecosystems, and temperature also affects soil moisture availability by regulating evapotranspiration, thus affecting ecosystem process. From the aspects of community composition and structure, vegetation phenology, coverage and productivity, and water conservation function by ecosystems, this paper reviewed the series of impacts caused by changed water resources on the Tibetan Plateau ecosystems in recent years, and the underlying mechanism was further revealed. The shifted water conditions led to changes in community coverage, …

“Water Is A Human Right”: Exploring The Paradox Of Framing Water As A Human Right In A Hostile Political Climate, Sabrina Kozikis

Biennial Conference: The Social Practice of Human Rights

Many communities across the United States experience challenges in accessing clean and affordable water. In response, civil society and grassroots organizations are using a human rights framework to advocate for safe and affordable services for all. This is a curious trend, given that the United States is a country in which human rights, specifically socio-economic rights, are not recognized as relevant for domestic policy and even met with hostility. This study explores this tension: why do civil society actors, grassroots organizers, and national level advocates in the United States use a human rights framework to advocate for access to clean …

Quantifying The Extent Of Wildfire Impacted Streams In The Western United States, Grady Ball

Water Resources Professional Project Reports

Beginning in the mid-1980s, the number of fires and acres burned by wildfire in the United States has grown at an explosive rate. Several factors, anthropogenic and natural, have converged to create a new era of high frequency, high intensity fires, which is predicted to continue until at least mid-century. Investigations into wildfire impacts have largely focused on post-fire impacts on terrestrial systems, while effects on aquatic ecosystems have been underrepresented. The growing threat of fire to streams has accelerated the need for germane information regarding the spatial extent of fire impacts on watersheds and post-fire impacts to aquatic systems. …

Water, Water, Anywhere?: Protecting Water Quantity In State Water Quality Standards, Julie F. Youngman

Indiana Law Journal

Although much of the earth’s surface is covered with water, less than one percent of water is available for human use. Water is becoming progressively scarcer worldwide, as demand increases and pollution, drought, and climate change jeopardize access to clean water. The United States is no exception to that trend. Effective regulation of water supplies can blunt the impacts of water scarcity. This Article suggests that states can—and should—regulate instream flows and lake levels in their federally-mandated water quality standards, with an eye toward conserving scarce water resources. Regulating water quantity as an element of water quality is not only …

Allocating Consumptive Water Rights In A Riparian Jurisdiction: Defining The Relationship Between Public And Private Interests, Lynda L. Butler

Lynda L. Butler

Historically, water consumption in the eastern United States has been governed by the common-law riparian doctrine. Fashioned to protect the domestic uses of private individuals in a largely agrarian society, the doctrine is not well suited to today's environment in which the demands of public users have grown enormously. Even in the East, where water has long been abundant, the effects of increased consumption, pollution, and periodic drought have brought the continued viability of the doctrine into question. Professor Butler examines the legal standards which have developed under the riparian doctrine and identifies three principal areas in which the doctrine …

Fate Of Hydrous Fe-Rich Silicate Melt In Earth's Deep Mantle, Zhixue Du, Jie Deng, Yoshinori Miyazaki, Ho Kwang Mao, Bijaya B. Karki, Kanani K.M. Lee

Faculty Publications

Density of silicate melt dictates melt migration and establishes the gross structure of Earth's interior. However, due to technical challenges, the melt density of relevant compositions is poorly known at deep mantle conditions. Particularly, water may be dissolved in such melts in large amounts and can potentially affect their density at extreme pressure and temperature conditions. Here we perform first-principles molecular dynamics simulations to evaluate the density of Fe-rich, eutectic-like silicate melt (E melt) with varying water content up to about 12 wt %. Our results show that water mixes nearly ideally with the nonvolatile component in silicate melt and …

Enumeration, Isolation, And Detection Of Campylobacter Species From Food Stuffs, Fecal Samples, And River Water Of East Tennessee, Molly Albin West

Doctoral Dissertations

Campylobacter species (spp.) are a leading cause of bacterial foodborne illness. These Gram-negative, microaerophilic microorganisms are found within the intestinal tracks of warm-blooded animals and in humans can cause a gastroenteritis, campylobacteriosis. Recent outbreaks are linked to raw milk, water, and puppies; however, these outbreak isolates have expressed antibiotic resistance, a main treatment line for campylobacteriosis. While Campylobacter spp. detection improves, cases are mainly sporadic and largely underreported. East Tennessee counties experience a higher prevalence of campylobacteriosis compared to other regions of the state based upon Tennessee Department of Health (TDH) surveillance. It is important for researchers to explore the …

Miniature Water Ion Thruster; 1 Km/S-Class Delta-V For A 6u Cubesat, Yuichi Nakagawa, Yasuho Ataka, Hiroyuki Koizumi, Kimiya Komurasaki

Small Satellite Conference

A propulsion system gives CubeSats the capacity to change their orbit on their own, and in terms of achieving a large delta-V, electric propulsion has an advantage. Installing the electric propulsion on CubeSats has difficulties such as a high-pressure gas system, electrical components, and the drop of the efficiency because of the miniaturization. To clear these problems, the water ion thruster is proposed as a candidate for the CubeSats’ electric propulsion. Water has an absolute advantage of applying for CubeSats’ propulsion system in the point of safety. In addition, water is a liquid phase at room temperature and atmospheric pressure, …

The Bioaccumulation Of Cyanotoxins In Aquatic Food Webs, Amanda Lee Murby Mcquaid

Doctoral Dissertations

Cyanobacteria are naturally occurring photosynthetic bacteria, ubiquitous in nature. Increases in temperature and nutrients have supported the proliferation of cyanobacterial growth globally, especially in freshwater systems. Many taxa can produce biotoxins referred to as “cyanotoxins”. While toxic cyanobacteria are a growing public health concern, little is known about the accumulation of cyanotoxins in lake food webs. This research investigates the seasonal occurrence and the potential role of toxic cyanobacteria in two lakes of contrasting water qualities and food web structures. Objectives of this study were to test the bioaccumulation of microcystins (MCs) and beta-methyl-alanine-amino acid (BMAA) in zooplankton. I further …

Adsorption Driven Regolith-Atmospheric Water Vapor Transfer On Mars: An Analysis Of Phoenix Tecp Data, Holly Nicole Farris

Graduate Theses and Dissertations

NASA’s Phoenix mission allowed for investigations of Martian diurnal water vapor cycles through the collection of temperature, relative humidity, and electric conductivity data by the Thermal and Electric Conductivity Probe (TECP) instrument. Using this data and previous experimental data, we propose a regolith-driven adsorption-desorption regime at the Phoenix landing site, where parameters intrinsic to the regolith are controlling localized relative humidity at the surface. To constrain these parameters, we model adsorption as a function of temperature and relative humidity across various Mars-relevant materials, defined by two layer-based adsorption theories: Langmuir (monolayer) and Brunauer-Emmett-Teller or BET (multilayer). Langmuir serves as an …

Application Of Semi-Hydrophobic Layers To Decrease Bare Soil Evaporation, Jesse Lee Barnes

UNLV Theses, Dissertations, Professional Papers, and Capstones

Evaporative water loss from bare agricultural soils is a primary area of water conservation research. Mulching is the commonly utilized method to decrease evaporative water loss. The most commonly utilized mulch is nonbiodegradable polyethylene sheeting because it tends to decrease evaporative water loss and increase crop yields more than environmentally friendly mulches. This study aimed to test the utility of sand coated with polymerized soybean oil (i.e., hydrophobic sand) as a treatment to reduce bare soil evaporation and an alternative to current practices. Evaporation rates were measured in laboratory soil columns containing both treated and untreated soils. Treatment parameters were …

Near-Infrared Observations Of Herbig Ae/Be Stars, Steven Cade Adams

All Dissertations

One of the most open-ended philosophical questions a person can ask is ``Where did we come from?" This question can be interpreted and approached from a multitude of angles. The work presented here will be investigating this question from the astronomical/physical perspective by studying the astronomical objects that are thought to be the immediate precursors to solar systems like our own. In order to determine how we came to be, we must first learn how our home was created.

My research area focuses on the study of the circumstellar disks around intermediate mass (2 - 8 Mʘ) young stellar objects, …

The Position Of Water And River In Classical Persian Literature, Bastian Zulyeno

International Review of Humanities Studies

Water is one of the four elements (water, fire, soil and wind) that are most important in the history of human civilization. In the history of literature and religions in the world, water in the general picture is symbolized as a purification medium for humans to achieve happiness in life. For example, the story of the journey of Iskandar Zulkarnain and the Prophet Khidir in searching for springs of life, as well as the Prophet Moses who was washed away in the Nile, and so forth many stories and legends related to water. The Euphrates and Tigris rivers are two …

Expanding Instream Flows To Protect Ecosystems In Overallocated River Basins, Belize Lane, David E. Rosenberg

All In-stream Flows Material

Utahns are expressing a rapidly growing interest in protecting and enhancing instream flows for outdoor recreation and environmental benefits (Endter-Wada et al. 2015). However, many Utah rivers are already over-allocated for agricultural, municipal, hydropower and other water uses, making it difficult to procure additional water for instream flows. ‘Use it or lose it’ western water law and mentality encourages Utahns to use water rather than return it to rivers and ecosystems.
