Uncovering The Mysteries Of Retention Ponds: Comparing The Abundance And Type Of Microplastics In Storm Water Ponds In London Ontario, Natalie Rose Minda 2022 Western University

Uncovering The Mysteries Of Retention Ponds: Comparing The Abundance And Type Of Microplastics In Storm Water Ponds In London Ontario, Natalie Rose Minda

Undergraduate Student Research Internships Conference

Microplastics are plastics <5 mm (Liu, 2019; Arthur et al., 2009). They are created in two ways: Intentionally or from the fragmentation of larger pieces of plastic (National Ocean Service, 2021). They can negatively impact human, wildlife and ecosystem health in many ways depending on the exposure, type, size, and shape of the microplastic (Campanale, 2020). Retention ponds are often created in neighborhoods to collect water in order to prevent flooding. They also often serve as habitat for wildlife. Sediment samples were collected in two ponds in London Ontario both dredged in 2016. Samples were processed in the lab and further analyzed under the microscope to isolate the microplastics. Results have not been determined yet, but the abundance and type of microplastic varies in both ponds. Plastic pollution in retention ponds should be considered more, as it poses a threat to human and ecosystem health.

A Qualitative Look Into Repair Practices, Jumana Labib

Undergraduate Student Research Internships Conference

This research poster is based on a working research paper which moves beyond the traditional scope of repair and examines the Right to Repair movement from a smaller, more personal lens by detailing the 6 categorical impediments as dubbed by Dr. Alissa Centivany (design, law, economic/business strategy, material asymmetry, informational asymmetry, and social impediments) have continuously inhibited repair and affected repair practices, which has consequently had larger implications (environmental, economic, social, etc.) on ourselves, our objects, and our world. The poster builds upon my research from last year (see "The Right to Repair: (Re)building a better future"), this time pulling …


Exploring The Use Of Covellite As A Proxy For Corrosion Of Native Copper By Sulphur Reducing Bacteria, Manan K. Joshi 2022 Western University

Exploring The Use Of Covellite As A Proxy For Corrosion Of Native Copper By Sulphur Reducing Bacteria, Manan K. Joshi

Undergraduate Student Research Internships Conference

We are analyzing the effect of sulphate reducing bacteria on native copper, and using that evidence to further support the initiative of having a deep geological repository to store nuclear material. Sulphate reducing bacteria are a concern for the deep geological repository as they cause the corrosion of regular copper. However native copper has gone billions of years without corrosion, which could either mean that it had not been exposed to sulphate reducing bacteria over the billions of years, or native copper is able to withstand corrosion despite the contact of sulphate reducing bacteria. We can find out by trying …

Investigating The Causes Of Stope Instability At Golden Valley Mine, Ashley Ruvimbo Sabao, Prosper Munemo, Peter Kolapo

Journal of Sustainable Mining

The study is based on mining operations that are concentrated in a ground exposed to flooding with varying stope dimensions. Stope stability was assessed in the four stopes, which resembled the mine’s different ground conditions using the stability graph complemented by the equivalent linear over break slough (ELOS) stability approach. The stability graph showed that the stopes in rock masses exposed to flooding fell in the potentially unstable and caving zones whereas the ones that were not affected by flooding fell in the stable zones. The ELOS approach showed that mining the previously flooded rock masses resulted in high over-breaks …


Unplanned Dilution Prediction In Open Stope Mining: Developing New Design Charts Using Artificial Neural Network Classifier, Sultan Korigov, Amoussou Coffi Adoko, Fhatuwani Sengani 2022 a Nazarbayev University, School of Mining and Geosciences

Unplanned Dilution Prediction In Open Stope Mining: Developing New Design Charts Using Artificial Neural Network Classifier, Sultan Korigov, Amoussou Coffi Adoko, Fhatuwani Sengani

Journal of Sustainable Mining

Minimizing dilution is essential in open stope mine design as excessive unplanned dilution can compromise the operation's profitability. One of the main challenges associated with the empirical dilution graph method used to design open stopes is how to determine the boundary of the dilution zones objectively. Hence, this paper explores the implementation of machine learning classifiers to bridge this gap in the conventional dilution graph method. Stope performance data consisting of the stope dilution (unplanned dilution), the modified stability number, and the hydraulic radius were compiled from a mine located in Kazakhstan. First, the conventional dilution graph methods were used …


Perspectives On Sustainability In Short-Term Faculty-Led Programs, Amanda Staton 2022 SIT Graduate Institute/SIT Study Abroad

Perspectives On Sustainability In Short-Term Faculty-Led Programs, Amanda Staton

Capstone Collection

Sustainability is a relatively new topic to the field of International Education. Despite this, its importance is tantamount for the continuation of the industry for future generations. The industry’s significant negative environmental impacts from international student mobility poses a real barrier to the continuation of the industry due to climate change. This research emerged due to the lack of existing research on sustainability in Study Abroad, especially short-term faculty-led programs, which are currently the most popular modality of Study Abroad. Short-term faculty-led programs currently hold a reputation in existing literature for being the most unsustainable form of Study Aboard with …

Novel Approach For The Destress Blasting In Hard Rock Underground Copper Mines, Piotr Mertuszka, Marcin Szumny, Krzysztof Fuławka, Piotr Kondoł

Journal of Sustainable Mining

The present study investigates the possibility of developing a novel method for reducing seismicity and rockbursts in deep underground mines based on modifying drilling and blasting patterns. The main goal was to develop and implement firing patterns for multi-face production blasting, which allow increasing the capability of inducing stress relief in the rock mass, manifested in the seismic event. This method may improve stability control in underground workings, and mitigate risks associated with the dynamic effects of rock mass pressure compared with currently used methods. Thus, the seismic energy may be released immediately after blasting in a controlled way. For …

The History Of Air Quality In Utah: A Narrative Review, Logan E. Mitchell, Christopher Zajchowski 2022 Old Dominion University

The History Of Air Quality In Utah: A Narrative Review, Logan E. Mitchell, Christopher Zajchowski

Human Movement Sciences Faculty Publications

Utah has a rich history related to air pollution; however, it is not widely known or documented. This is despite air quality being a top issue of public concern for the state’s urban residents and acute episodes that feature some of the world’s worst short-term particulate matter exposure. As we discuss in this narrative review, the relationship between air pollution and the state’s residents has changed over time, as fuel sources shifted from wood to coal to petroleum and natural gas. Air pollution rose in prominence as a public issue in the 1880s as Utah’s urban areas grew. Since then, …


The Effect Of Water Management And Ratoon Rice Cropping On Methane Emissions And Harvest Yield In Arkansas, Marguerita Leavitt 2022 University of Arkansas, Fayetteville

The Effect Of Water Management And Ratoon Rice Cropping On Methane Emissions And Harvest Yield In Arkansas, Marguerita Leavitt

Graduate Theses and Dissertations

Sustainable intensification of rice farming is crucial to meeting human food needs while reducing environmental impacts. Rice produces 8% of all anthropogenic CH4, which is a potent greenhouse gas. CH4 emissions can potentially be reduced by cultivation practices that minimize the number of days the fields are saturated, such as dry-seeding instead of water-seeding and irrigation using the alternate wetting and drying (AWD) technique instead of delayed, continuous flooding (DF). Ratoon cropping, wherein a second crop of rice is grown from the harvested stubble of the first crop, can be used to produce additional yield with minimal labor, but may …


Effects Of Excessive Soil Phosphorus Accumulation On Loblolly Pine (Pinus Taeda L.) Seedlings, Hannah C. Bays 2022 Stephen F. Austin State University

Effects Of Excessive Soil Phosphorus Accumulation On Loblolly Pine (Pinus Taeda L.) Seedlings, Hannah C. Bays

Electronic Theses and Dissertations

Many landowners in East Texas apply poultry litter to pastures as a source of nitrogen (N) for forage crops. After many years of repeated poultry litter application, soils can accumulate extremely high extractable phosphorus (P) concentrations, sometimes over 1000 mg kg-1 of plant available P. Landowners report the conversion of these pastures to loblolly pine (Pinus taeda L.) plantations is often problematic, with poor seedling survival and abnormal tree growth. This study was conducted to assess the effects of excessive soil phosphorus on loblolly pine seedlings. An outdoor pot study was conducted using bare root seedlings and triple …

A Scarcity Of Biospheric Values In Local And Regional Reporting Of Water Issues: Media Coverage In The Floridan Aquifer Region, Sadie Hundemer, Debbie Treise, Martha Monroe

Journal of Applied Communications

The values invoked by journalists in the reporting of water issues influence public support for water policy and the assessment of water tradeoffs. This qualitative framing analysis of water coverage from six newspapers in the Floridan aquifer region from 2010 to 2018 reveals the values used to stimulate reader engagement on a range of water challenges including weather, residential behavior, agriculture, algae, industry, springs, energy, municipalities, and fecal matter. Results reveal a hierarchy of value frames that prioritizes economics and human health, thereby attending primarily to the motivations of egoistic and social-altruistic individuals. The ecosystem implications of deteriorated water conditions, …
