Effect of Assay Medium pH on Inhibitory Ability of \u3ci\u3eStreptomyces\u3c/i\u3e
Get PDFStreptomyces bacteria from soil often produce antibiotics which inhibit growth of other microbes. When comparing Streptomyces’ inhibitory ability between different soils, it may be important to match the pH of the medium used in assays to the pH of the soil they came from. We assayed Streptomyces isolates collected from a long-term agricultural experiment with nitrogen-fertilized and non-fertilized treatments to determine their ability to inhibit growth of other bacteria by producing antibiotics. Average soil pH was 6.8 in fertilized soil and 7.2 in non-fertilized soil. We dotted isolates on a glucose-asparagine agar medium adjusted to different pH values and overlaid them with a non-pathogenic Streptomyces standard to measure their inhibitory ability. Some isolates produced different inhibition zone sizes depending on medium pH. However, response to assay medium pH did not differ significantly among isolates from soils of different pH. More tests are needed to determine whether it is necessary to match the medium pH to the pH of the soil the isolates came from when comparing prevalence of antibiotic production among Streptomyces from different soilshttps://digitalcommons.morris.umn.edu/urs_2024/1003/thumbnail.jp
This is How the West Ends : A Content Analysis of Conservative Youtubers Notions of Western Excellence
Get PDFIn 2023, YouTube was one of the most used social media platforms in the United States alone. While existing scholarship (Finlayson 2022) has observed linkages between right-wing social media and distrust in institutions of government, family, and others, I seek to understand how conservatives use YouTube as a means to teach their audience racialized, gendered, and nationalistic ideas about the Western hegemonic order. To examine this issue, I conducted an in-depth qualitative content analysis of three key conservative content creators: Ben Shapiro, Matt Walsh, and Michael Knowles. Two videos were chosen within each creator\u27s profile using keyword searches such as “Anti White” and “DEI”. Preference was given to videos published within the last 6 months and for videos more than 5 minutes and less than 60 minutes. Total watch time amounted to 139 minutes. I found that these creators most commonly suggest that whiteness, masculinity, and Western society as we know it are under attack. The culprit of these attacks in their point of view are efforts that promote diversity, equity, and inclusion in the workplace, schools, and other institutions. By utilizing a “draw your own conclusions” framework, conservative creators can both distance themselves from their ideological teaching and create a community with which followers of this content can connect with. Ben Shapiro, Matt Walsh, and Michael Knowles have gained, maintained, and grown their following on the basis of this shared sense of community that promotes extremely violent, racialized, gendered, and nationalistic ideas.https://digitalcommons.morris.umn.edu/urs_2024/1004/thumbnail.jp
Representation Theory and Burnside\u27s Theorem
Get PDFIn this paper we give a brief introduction to the representation theory of finite groups, and by extension character theory. These tools are extensions of group theory into linear algebra, that can then be applied back to group theory to prove propositions that are based entirely in group theory. We discuss the importance of simple groups and the Jordan-Hölder theorem in order to prepare for the statement of Burnside’s pq theorem. Lastly, we provide a proof of Burnside’s theorem that utilizes the character theory we covered earlier in the paper
Bob Dylan and Grassroots Shakespeare in Minnesota
No full textWhen talking about his creative process, Bob Dylan once said: I\u27ve been trying for years to come up with songs that have the feeling of a Shakespearean drama, so I\u27m always starting with that. Shakespeare inspires us to greatness. Do you want to partake in greatness? Then come to the Barber Lecture presented by Katherine Scheil, a Shakespeare professor at the University of Minnesota Twin Cities.https://digitalcommons.morris.umn.edu/barber/1004/thumbnail.jp

Point Deductions in World Football: The Issue of Financial Fair Play
Get PDFThe acronym FFP may not mean much to the casual football supporter, but to front-office officials and owners of football’s richest clubs, these three letters could mean doomsday. Financial Fair Play, FFP, was created by the European Football governing body UEFA to regulate, monitor, and improve the economic and financial capacity of football clubs. John W. Henry, principal owner of Liverpool Football Club and the Boston Red Sox, has been a vocal supporter of FFP since its inception and said the following in an interview with the Tomkin Times, The mandate of financial fair play in Europe is for clubs to live within their means.” Since FFA was implemented in 2011 by UEFA, major clubs across Europe have been subjected to internal investigations and point deductions including the likes of Juventus, Manchester City, Everton, Paris Saint-Germain, and other high-profile clubs. The issue of Financial Fair Play is much deeper than just a way to keep football clubs from going bankrupt. It is also a system put in place to try and keep the playing field somewhat level between European giants and smaller clubs. In the past few years, point deductions and penalties have been handed out to clubs that violated the FFP guidelines, but what purpose do these penalties serve? Is a point deduction the most ethical and effective way to punish a club for playing outside of the rules? In this essay, I will examine multiple cases of Financial Fair Play violations and break down the ethical dilemmas that the situation produces by using sources of philosophy
3D Pictorial Representations of O\u3csub\u3e2\u3c/sub\u3e\u3csup\u3e-\u3c/sup\u3e and HO\u3csub\u3e2\u3c/sub\u3e Compared to DFT Results
Get PDFThe Linnett Double Quartet (LDQ) (1) and Bohr Orbit Bonding (BOB) (2) methods were used to accurately represent the spin density distribution for superoxide (O2 -) and hydroperoxyl radical (HO2). These structural pictures were superimposed on the spin density plot produced by DFT. The Valency Interaction Formula (VIF) method (3) was also applied to these molecules and it matched the NBOs from NBO analysis of DFT results. The interaction between O2 - and H2O were analyzed and the stronger basicity of the beta-spin electrons of superoxide was identified by looking at the LDQ structure and confirmed with NBO analysis. The bond formation of a proton with O2 - was predicted with the VIF method. The Keq found experimentally by Bielski et al. (4) for the reaction HO2 + H2O ⇋ O2 - + H3O was further supported by DFT computations from this research
