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 ...


356— Conodonts, Microtektites, And Thermal Alteration, Of The Jefferson Formation, Upper Devonian, Wyoming, Joshua Yanuck, Ryan Lee Apr 2021

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

GREAT Day

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 Apr 2021

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

GREAT Day

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 Apr 2021

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 ...

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).

Carrier-Free Chemo-Ptt/Pdt Ionic Nanomaterials For Combination Cancer Therapy, Samantha Macchi Mar 2021

Carrier-Free Chemo-Ptt/Pdt Ionic Nanomaterials For Combination Cancer Therapy, Samantha Macchi

Arkansas Women in STEM Conference

Herein, we describe a carrier-free combination nanodrug for treatment of cancer. In this work, we combined a photothermal compound and a chemotherapeutic drug using ionic liquid chemistry. We utilized a facile, one-step metathesis approach to replace the counter cation of a near infra-red (NIR) dye (photothermal agent) with a chemotherapeutic cation to synthesize an ionic material-based combination cancer therapy drug to deliver multiple mechanisms simultaneously. The nanodrugs were developed by using a reprecipitation method. The detailed photophysical properties of this new combination therapy molecule was investigated in ethanol solution as well as in nanoparticles forms in aqueous media. The singlet ...
