Mapping Of Non-Native Invasive Plant Species Using Remote Sensing And Gis: Assessment Of Human Impact On Kudzu (Pueraria Montana) Spread, Harshitkumar Godhasara

Scholars Week

Remote sensing methods provide tools to identify and map non-native plants. Biophysical characteristics of plants can be utilized to recognize and distinguish non-native invasive plants from other native plant species. Kudzu is an invasive plant, which causes economic loss and decreases biodiversity. Moreover, kudzu doubles emission of nitric oxide and increases ozone pollution. The impact of human activities on the spread of noxious plant species like kudzu can be assessed utilizing remote sensing and geographic information systems (GIS) tools. Kudzu spread in the USA was mapped using in situ data including the actual coordinates of kudzu sites. Geographic distribution of …

Pilot Study Exploring The Impact That Laboratory ​Instruction Has On A Student's Stem Professional Identity​ ​, Datiel Dayani, Dr. Michelle Head

Symposium of Student Scholars

STEM professional identity serves as one lens through which researchers have used to study factors that influence achievement in chemistry courses and persistence in a STEM major. The literature has proposed that the high attrition rate among STEM majors may result from the student’s evolving professional identity, motivational factors, and how they correlate a STEM career to their future aspirations. There is limited insight into how laboratory classes and teaching practices affect a student’s professional identity development. To investigate this, this study employed James Marcia’s identity development theory to understand the relationship between a student's identity status and their perception …

Speed And Accuracy For Partial Differential Equation Solvers, Aidan Grasby

Undergraduate Student Research Internships Conference

This Research project consisted of testing multiple software used to solve partial differential equations to determine the fastest solver while not compromising other aspects such as accuracy. The larger project involved using electrodes and electric fields to treat brain tumours. An optimization program is required to determine electrode placement and this program must solve partial differential equations to determine the electric field for each electrode configuration. This optimization step is extremely slow so it is critical a faster partial differential equation solver is found. Therefore, I tested various software to determine the fastest solver that could then be linked with …

Studies Of Subvarieties Of Classical Complex Algebraic Geometry, Wenzhe Wang

Undergraduate Student Research Internships Conference

My project in this USRI program is to study subvariety of classical complex algebraic geometry. I observed the orbit of elements in the unit sphere in space ℂ² ⊗ ℂ², the structure of unit sphere of ℂ² ⊗ ℂ². After this, I tried to generalize the result to ℂ^n ⊗ ℂ^n.

A Paleoseismic Study Of The Twin Lakes Fault, Mount Hood Fault Zone, Oregon, Charlie Carr, Ashley R. Streig

McNair Symposium

Recent geologic mapping on high-resolution topography from lidar has led to the discovery of a zone of active faults on Mount Hood. The Mt. Hood Fault Zone consists of four separate faults, and stretches ~55 km from south to north, and crosses the summit of Mount Hood. The focus of this study is the northern section of Twin Lakes Fault, which lies directly south of Mount Hood and adjacent to OR35 and the White River. Lidar topography reveals the west side down normal displacement on the Twin Lakes fault. The highest tectonic seismicity rates in the Mount Hood area occur …

How Risk-Related Statistics, As Reported In News And Social Media, Are Linked To The Use Of The Public Transit System, Prashiddhi Pokhrel

Thinking Matters Symposium

Due to the pandemic, people have started relying more on televisions, news, social media, and other news outlets for guidance. Moreover, with the increasing amount of news, data, and information there is also an increase in the amount of misleading statistics. People’s opinions and decisions significantly depend on the data, statistics, and information that they are exposed to, as well as their sources. For this project, we want to look at how information and its sources are affecting the decision made by the general public for the usage of the Portland Transit System. It is very important to know why …

356— Conodonts, Microtektites, And Thermal Alteration, Of The Jefferson Formation, Upper Devonian, Wyoming, Joshua Yanuck, Ryan Lee

GREAT Day Posters

The Jefferson Formation, composed of two members, a limestone and dolomite dominated layer called the lower member, and the dolomite-dominated Birdbear Member, is distributed throughout southern Montana and northern Wyoming. Samples were taken from multiple levels within the Birdbear Member, dissolved in buffered 10% formic acid, and the insoluble residue separated using heavy liquid. The heavy fraction was searched for conodonts and microtektites. Conodonts indicate the Middle Frasnian stage of the Upper Devonian and thermal heating of less than 80 degrees Celsius. Microtektites, speculated to occur in the interval corresponding to the Alamo Impact in Nevada, were not found.

062— Nano-Size Dependence In Aggregation Process Of Beta 2 Microglobulin Coated Gold Colloids, Kaylee A. Hausrath

GREAT Day Posters

The formation of the aggregates of the beta 2 microglobulin (b2m) coated nano-gold colloids were investigated for various nanogold colloid sizes ranging between 10 nm and 100 nm. The aggregation process was considered to be initiated by the selfassembly of b2m by transforming the folded to the unfolded structure under highly acidic condition (pH < 4). The formation of the aggregates were monitored by a peak shift of surface plasmon resonance (SPR) band as a function of number of free b2m available. As for relatively smaller size of gold colloid diameter a gradual aggregation process was observed. The size of the aggregates was considered to increase monotonically as the b2m was added. On the other hand, as for relatively larger diameter of gold colloid, stepwise aggregation process was observed. So that the aggregates of a particular size was formed at a certain threshold of the concentration of available free b2m. The majority of the gold surface of the smaller gold size was easily covered and support the aggregation even at the lower concentration of b2m.

Monitoring Chlorophyll A And Pheophytin At Crabtree Swamp, James Blankenship

Undergraduate Research Competition

The two chemicals compound we will be looking at include Chlorophyll A and Pheophytin. These two chemicals are common in most waters around the world. While they are helpful for the ecosystem, like most everything, having too much can also be harmful. Having a high concentrate of Chlorophyll A can result in foul smell and green scum on the bottom and surface of water. Likewise, pheophytin can be harmful when it comes to dissolving oxygen in water. This can result in erosion around the water source and can lead to unwanted chemicals in water (4). The results discussed will show …

Absorbance At The Crabtree, Jaquon Williams

Undergraduate Research Competition

Water scarcity is a growing concern across the world in this document we investigate Crabtree swamp, that’s in Conway, SC. Water absorption is the amount of water taken up by flour to achieve the desired consistency and create a quality end-product. Yet, in this case, we're talking about the Crabtree swamp land area. The goal of this research project is to compare and contrast water absorbance in the area.

The purpose of this study is to naturalize the aquatic ecosystem processes in Crabtree Swamp and improve the survivability of resources of regional significance that have been identified. Resources such as …

S3: Post-Covid-19 Recovery Care Plan For Older Adults With Continuing Symptoms Of Breathlessness And Fatigue, Nancy M. Bryan, Marie Wright-Rolf Edd, Msn, Rn, Siboney Zelaya Ph.D., Mph, Msn Ed, Rn, Justin Carbonel

Annual Research Symposium

Background:

The CDC research actively continues gathering information related to short and long-term symptoms that remain following the acute phase of Covid-19 diagnosis (CDC, 2020).

Fatigue and shortness of breath are listed among the most commonly reported long-term symptoms of Covid-19:

1. Fatigue
2. Shortness of Breath
3. Cough
4. Joint Pain
5. Chest Pain (CDC, 2020).

Evidence suggests that older adults over the age of 60 who have multiple comorbidities are more susceptible and are at a higher risk of contracting the Covid-19 virus thus potentially prolonging recovery time post diagnosis (Greenhalgh, Knight, A’Court, Buxton, & Husain, 2020).
