Evaluation Of Nitrous Oxide Emissions From Furrow-Irrigated Rice On A Silt-Loam Soil In Arkansas, Jordan M. Slayden

Graduate Theses and Dissertations

As the number one rice (Oryza sativa)-producing state in the United States, Arkansas also ranks fourth as the largest user of groundwater. Recently, due to the development of drought- resistant hybrid cultivars, the furrow-irrigated rice production system has become an increasingly popular alternative to traditional flood-irrigated production with respect to conserving groundwater and maintaining yield. However, other environmental parameters, like greenhouse gas emissions, specifically nitrous oxide (N2O), have yet to be evaluated under furrow-irrigated rice. The objectives of this study were to i) evaluate the effects of site position (i.e., up-, mid-, and down-slope) and tillage treatment [i.e., conventional tillage …

Rehydrating The Landscape At Yanget, Geraldton, Western Australia, Jamie Bowyer, Rod O'Bree

Natural resources published reports

Rod and Bridie O’Bree’s farm is 25 km east of Geraldton in the Northern Agricultural Region of Western Australia. The long-term rainfall average is 486 mm although that has dropped to 354 mm over the last 30 years. They run a 150 head beef cattle herd, fatten 500-700 lambs annually and have a 40-60 head horse stud on the farm. They purchased the farm early in 2008 after one of the worst droughts in the area. There was little to no vegetation, brown or green, across the farm and all of the water from a 25 mm rain event ran …

Longleaf Pine Restoration In The South Carolina Sandhills Wiregrass Gap, Jacob W. Murray

All Theses

Longleaf pine restoration has been a topic of great concern and intrigue in the southeast and has taken on new fervor in recent decades as restoration methods continue to develop. Many landowners and forest managers are now pursuing ecological forestry and restoration ecology in great numbers as a new form of land management. However, niche regions can often be overlooked, as is the case with the Carolina Sandhills Wiregrass Gap, an area devoid of wiregrass and one that is on the outskirt regions of the historical longleaf pine range. Field studies were conducted pre- and post-harvest during two growing seasons …

Raising The Level Of Environmental Concern Of Senior Students Taking The Electronics Engineering Laws And Ethics Through Climate Change Awareness Study, King Harold A. Recto, Romano Q. Neyra

Electronics, Computer, and Communications Engineering Faculty Publications

Two general areas that future electronics engineers are honed are competence and character. Most of the courses he takes fall in the general area of competence. This includes subjects like Circuit Theory, Electronic Design and Analysis, Communication Systems, and the like. Subjects dealing with character, in contrast, are limited. In some universities, it may just be Electronics Engineering (ECE) Laws and Ethics and the focus is on “engineering made by man for man.” In this traditional view of Engineering, the environment is often neglected since it’s not about “man” (as opposed to the “society”). Over the last years, however, concerns …

Gravity Field Changes During Deep Exploitation Of The Coal Longwall And Their Relation To Stress Distribution And Seismic Activity, Łukasz Kortas

Journal of Sustainable Mining

Mining operations cause volumetric deformations within the rock mass and changes in its density, to which the gravimetric method is sensitive. These changes are particularly well seen in periodic measurements of the local gravity field. The paper analyses the relationship between the movement of a longwall in a coal seam and the change in the distribution of the gravity field in time and space observed on the ground surface. Relative gravimetric measurements were carried out in six series between 2018 and 2020; before the start of coal extraction, with the progress of the longwall and after the cessation of mining. …

Study Of The Relationship Of Tidal Changes In Gravity With The Time Of Mining Tremors In The Area Of The Mining Longwall In A Coal Mine – Case Study In Uscb, Poland, Sławomir Siwek

Journal of Sustainable Mining

Deep mining of coal deposits in Upper Silesia Coal Basin in Poland over several hundred years has led to disturbances in the natural state of equilibrium. As a result of changes in stress distribution, mass distribution (changes in gravity forces) and deformation of the rock mass, seismic tremors with energy reaching up to 10E+09J are generated. In this paper, the time of mining tremors occurrence is linked with changes in the gravitational load of the rock mass caused by litosphere tides, which are considered to be one of the factors leading to occurrence of natural seismic tremors. The analysis used …

Feasibility Discussion Of Potential Carbon Offsetting Options For Nebraska, Andrew Mwape

School of Natural Resources: Faculty Publications

Conclusion

Highlighting the advantages and disadvantages of carbon offsetting options in the context of the state of Nebraska, this discussion shows that the choice and decisions about which option is better than the other depends on the interests at play and expected outcomes of the participation in carbon markets. However, irrespective of the motive to engage in emission reduction projects for carbon marketing, factors such as cost, and project efficiency can never be overlooked. Given the options discussed in this report, Nebraska has a lot of potential for carbon offsetting or emission reduction projects that would not only reduce and …

Blue Crab In The New York Area As An Indicator For Climate Change, Adelle Molina

Sustainability Seminar Series

In the northeast US, winters are getting warmer, shorter, and milder due to climate change. It is hypothesized that populations of some species near their northern range limit may experience elevated population growth rates owing to lower mortality in winter, higher growth rates in summer, and the synergistic relationship between these physiological processes. Blue crabs (Callinectes sapidus) in New York estuaries are close to their northern range edge and are potentially climate “winners” in this region. To provide advice to managers, we monitored blue crab populations in a coastal, lagoonal estuary and used a combined modeling approach to simulate the …

Efficient Management Of Nitrogen And Phosphorus At Centralized Water Reclamation Facilities, Helene Kassouf

USF Tampa Graduate Theses and Dissertations

A variety of process configurations are employed at municipal water reclamation facilities (WRFs), such as 5-stage Bardenpho, oxidation ditch, modified Ludzack-Ettinger (MLE) process, and sidestream recycle. However, all of these configurations face certain challenges in achieving optimum treatment of nitrogen and phosphorus. In this dissertation, the driving objectives were to: (1) quantitatively assess the fate of nitrogen and phosphorus (mass fluxes) at a treatment facility that employs biological nutrient removal, aerobic digestion, and sidestream recycle, (2) evaluate the performance of a microbial fuel cell (MFC) as a technology to remove nitrogen from sidestreams at a treatment plant that employs that …

Detecting Perturbations In Seawater Carbonate Chemistry With The Δ44/40ca-Δ88/86sr Multi-Proxy, Jiuyuan Wang

Sustainability Seminar Series

Ocean acidification is one predictable consequence of rising atmospheric CO2. Understanding how the seawater carbonate chemistry changed during historical climate changes will help us better predict the ocean’s response to the present one. In this talk, I will introduce a novel means for tracking changes of seawater carbonate chemistry: the δ44/40Ca-δ88/86Sr multi-proxy. I will exploit emergent properties of δ44/40Ca and δ88/86Sr systems from two extreme climatic events: the Cretaceous Oceanic Anoxic Event 1a (OAE1a, ~120 Ma) and the Neoproterozoic Marinoan deglaciation (~635Ma).

The Economics Of Residential Solar And Battery Storage: Analyzing The Impact Of The Joint Iou Proposal For Net Metering 3.0 In California, Candace E. Ybarra, Prashanth U. Nyer, John B. Broughton, Thomas A. Turk

Business Faculty Articles and Research

The California Public Utilities Commission (CPUC) is currently deciding on the structure of the next net metering program, which will determine how customers who install solar panels (and battery storage) under this new program will be compensated for excess energy that they export to the grid, and the additional fees that these solar customers will have to pay. The major investor-owned utility (IOU) companies in the state and some legislators have argued that the current net metering programs are far too generous to the customers and that they create an inequity by favoring the wealthy and causing a cost shift …

Giving Beets A Chance: Heavy Metal Accumulation In Mycorrhizal And Non-Mycorrhizal Crops At An Urban Farm, Eric Vukicevich

Sustainability Seminar Series

Urban, community farming seeks to provide access to affordable, healthy, culturally-appropriate produce via cooperatively-run growing spaces. However, the threat of contaminated soils so common to older cities can limit the scale of production and/or necessitates costly remediation efforts. Although there are rough guidelines outlining at what level a soil is unsafe for growing food, there are many uncertainties as to which crops might be safe in soils with slightly elevated (but below guidelines) levels of contaminants and to what degree soil biology affects uptake. We grew mycorrhizal and non-mycorrhizal root, leafy green, and fruit crops representing five different plant families …

New Methods For Assessing The Sustainability Of Wood-Burning Energy Facilities, Sarah Mittlefehldt, Erin Bunting, Emily Huff, Joseph Welsh, Robert Goodwin

Journal Articles

Methods to assess wood-based bioenergy projects have tended to focus on technological and physical constraints. Less is known about how longer-term environmental, economic, and social systems—the three pillars of sustainable development—have influenced technological development in the context of woody biomass energy. This research offers new methods for assessing the sustainability of wood-based energy projects by combining spatial analysis, semi-structured interviews, and archival data analysis. By integrating quantitative and qualitative methods, this project offers ways to understand how social and environmental dynamics from the past shape technological development in the future. A propensity analysis of biomass energy plants in Michigan, USA …

The Sustainability Institute Publications

Sustainable food systems education (SFSE) is rapidly advancing to meet the need for developing future professionals who are capable of effective decision-making regarding agriculture, food, nutrition, consumption, and waste in a complex world. Equity, particularly racial equity and its intersectional links with other inequities, should play a central role in efforts to advance SFSE given the harmful social and environmental externalities of food systems and ongoing oppression and systemic inequities such as lack of food access faced by racialized and/or marginalized populations. However, few institutional and intra-disciplinary resources exist on how to engage students in discussion about equity and related …

Modeling The Ambient Conditions Of A Manufacturing Environment Using Computational Fluid Dynamics (Cfd), Yang Liu

USF Tampa Graduate Theses and Dissertations

As manufacturing equipment evolve to higher speed and require high precision operations, the impact of environmental changes on machine accuracy becomes critical. Due to thermal expansion, the structure of the machine can change when ambient temperature varies. When the airflow in the laboratory changes, this also alters the operator's thermal comfort. Either the change in machine structure or operator comfort can ultimately affect machine accuracy. The manufacturing industry is currently using heating, ventilation, and air-conditioning (HVAC) systems to regulate the temperature of the working environment. However, since conventional HVAC systems determine whether to activate the HVAC system by collecting the …

Mega-Herbivores, Plants And Soils, Jennifer Adams Krumins

Sustainability Seminar Series

Ecosystem and plant ecologists understand that herbivory can have a profound influence on primary production and plant community structure. This can be seen in mass outbreaks of insect herbivores or the grazing activity of ungulate herds. Likewise, the same ecologists understand that plants interact closely in a bidirectional relationship with soil organisms and the ecosystem properties they moderate. Therefore, logically we hypothesize that herbivory will have either a direct effect on soil communities and their functioning, or at minimum, an indirect effect on the soils via the plants they support. My sabbatical research included participation in multiple programs studying the …

Medium Conditons And Influence Mechanism Of High Salinity Mine Water Transfer And Storage By Deep Well Recharge, Li Xin, Sun Yajun, Chen Ge, Wang Houzhu, Zhang Zhijun

Coal Geology & Exploration

In the arid and semi-arid regions of the Western China, there is not only a shortage of water resources, but also the problems of large mine water inflow and high salinity of mine water. In order to reduce the waste of water resources in the mining activities and protect water ecological environment in the region, it is proposed to treat the mine water by deeper well recharge to the aquifers under the coal seam based on the theories and technical methods such as mine water transfer and storage, water-preserving mining and coal-water dual resource coordinated mining. A test well project …

Medium Characteristics And Hydrodynamic Evolution Law Of High Salinity Mine Water Recharge In Deep Well, Liu Qi, Wang Weijun, Luo Bin, Wang Houzhu, Zhang Zhijun

Coal Geology & Exploration

The treatment and discharge of high salt mine water is one of the important factors affecting efficient coal mining in recent years. It is a worth exploring method to reduce the discharge of mine water by selecting the appropriate aquifer under the floor of the coal seam and transferring the high salt mine water to other places. Taking the X mine in the Ordos Basin as an example, the Baotashan sandstone and the deep Liujiagou Formation sandstone formation below the coal seam have transfer storage space. By mercury intrusion experiment and rock mechanics analysis, the two groups of formations were …
