College Algebra: A Key Element To Degree Completion, Christopher Charlie Jett, Gregory Downing

Journal of Humanistic Mathematics

College Algebra is often under scrutiny because it serves as a critical gateway to graduation for students enrolled in our nation’s undergraduate degree programs. In this paper, we problematize the authority typically ascribed to this course and discuss meeting students’ discipline-specific needs in core mathematics courses such as it. To help facilitate college student success with respect to mathematics course requirements, we recommend that educational constituents and leaders expand dual-enrollment opportunities, infuse culturally relevant practices, and leverage other core mathematics courses as alternatives to College Algebra. In doing so, we add to the ongoing conversation about addressing this issue in …

An Essay On Teaching And Learning Mathematics: Through The Lens Of Artificial Intelligence, Music, And Sports, James Diederich

Journal of Humanistic Mathematics

This essay is aimed at a wide audience: anyone who has engaged in learning or teaching math. It provides a unique perspective drawn from a mathematician’s interests in working with K-12 teachers, familiarity with artificial intelligence (AI), and amateur pursuits of learning to play an instrument and of learning a difficult sport. While I delve into these topics, no special background is needed in the slightest. In particular, I draw lessons from some failures in AI that reflect on why the conventional procedural approach to teaching and learning math fails many students. I also provide insight into how we learn …

Prime Numbers Are Written On Your Hand: You Simply Have Not Been Counting Correctly, Nona Servais Kamdem Simo, Awa Traore

Journal of Humanistic Mathematics

Prime numbers have resisted systematic description for over two millennia. We propose that part of the difficulty may lie in an insufficiently attentive examination of one’s own hands. In particular, we assign the natural numbers to the joints of the human hand according to a cyclic traversal protocol, and make a handful of observations which can naturally be translated into number-theoretic properties of prime numbers. We show that these properties lead us to natural activation thresholds of a unified three-phase sieve algorithm — the resulting framework provides, for the first time, a zone-based partition of the admissible space with explicit …

Mathematicians Against The Tide, Nicola Ciccoli

Journal of Humanistic Mathematics

Mathematicians in popular culture are often depicted as people obsessed by their studies but with little connection to society, poor social skills, mental issues and narrow interests, and more generally a dull life. Adding to these explicit stereotypes, subtler and more implicit ones also abound, regarding mathematicians’ gender, ethnicity, age; they are all supposed to be white middle-aged men. In this paper I describe a project aimed at disrupting such stereotypes that culminated in a book containing short comics and biographies of twentieth-century mathematicians that were, with respect to the perceived image of mathematicians, against the tide.

Piracy, Terrorism, And The Law: Differential Equations In Hostage Situations, Gabriel Hallevy

Journal of Humanistic Mathematics

Pirates have taken the crew of an American ship hostage. They promise to release the hostages only if another pirate who is held in an American prison for commission of piracy crimes against American citizens, is released. Should the U.S. government enter into negotiations with them? Should they send armed forces and risk the hostages? Should they release the prisoner immediately and unconditionally? The article models and analyzes possible policies regarding sensitive situations involving hostages and other related risks using differential equations. The solutions are surprisingly simple, but not necessarily intuitive. Our analysis aims to demonstrate how powerful mathematics is …

Grationality, With A Spoon, L. Jeneva Clark

Journal of Humanistic Mathematics

I introduced grationality at a 2025 sectional meeting of the Mathematical Association of America to install a handle on a concept akin to rationality of numbers, but in a geometric context. More specifically, we define a nice n-gon to be a regular n-gon with side lengths that are natural numbers; then a number n is grational if and only if there exists a nice n-gon such that its area equals the sum of areas of n congruent nice n-gons. In this paper I offer several examples of grational and non-grational numbers, followed by theorems about how the grationality of a …

Experimental Results With Various Herbicides In Established Alfalfa, Taib Saric, Refik Numic

IGC Proceedings (1977-2023)

5-year experiments with herbicides were run in the mixture of alfalfa, red clover, timothy grass, and Italian ryegrass. On untreated plots, in the 5-year average 72 weed plants were found per 1 m2 , belonging to 66 weed species. Among them most numerous were: Stellaria media, Veronica agrestis, Poa annua, Lamium purpureum,Taraxacum officinale, and Capsella bursa pastoris. The most efficient herbicide was Etazin, killing 88 % of weeds. None of the applied herbicides controlled perennial weeds. Etazin was tolerated by alfalfa, but was toxic to the other three crops. Kerb, Kerb-Mix, and Multi­tok were toxic to sown grasses, while …

Recommended Values For Dimensioning And Designing Sprinkler Irrigation In Industrialized Forage Plant Produc­Tion In The Gdr, Klaus Schwarz, Dieter Roth

IGC Proceedings (1977-2023)

With the transition to industrialized crop and animal production in the GDR, sprinkler irrigation of field forage plants and grassland, above all with sewage water and clean water +slurry mixtures, is becoming more and more important. It gets increasingly concentrated on field grass and grass/clover stands. The supple­mental water requirement is 210 to 270 mm/ year in case of clean-water sprinkling and up to 400 mm/year if sewage water is used. The hydro-modulus of the irrigation plants is be­tween 1.2 and 1.6 m3 /h/ha, depending on the simultaneity factor. In order to attain the required water quantity per unit of …

Sultan Qaboos University Journal For Science

In recent times, investigators have conducted extensive studies on carbon nitride-based photocatalytic materials. Earlier research mainly concentrated on the poly-condensation technique and the uses of the produced materials, whereas less attention was given to the starting precursors, which were broadly classified as nitrogen-rich. This research offers a complete examination of the appropriate precursors, highlighting their large-scale, economical, and safe production for carbon nitride-based materials. Safety evaluations of the precursors were examined, and a cost analysis was conducted to refine the choice of accessible precursors. Afterward, the surface area, photophysical, SEM, and electrochemical properties of the materials were characterized. The differences …

Assessing Amino Acids And Peptide Adsorption On Pristine Graphene In Aqueous Solution: Nmr Spectroscopy, Budoor S. Al Umairi, Rahma Al Busaidi, Walaa Sameer Aburayan

Sultan Qaboos University Journal For Science

Graphene offers tremendous potential for applications in biomedical and pharmaceutical areas, ranging from molecular diagnostics, biosensors, and prosthetics to implants and drug delivery. However, realising the full potential of graphene is blocked by a limited understanding of the nature and detail of its noncovalent interactions with biological molecules in aqueous dispersion, where such applications can be used. Here, we studied the adsorption of amino acids and peptide on graphene in water utilising Nuclear Magnetic Resonance spectroscopy by observing 1H signals of individual biomolecules when exposed to graphene. The peptide-graphene interactions appeared to be driven by the binding affinity of individual …

Photocatalytic Hydrogen Peroxide Production With Bi2Wo6/G-C3N4 Heterojunction Through S-Scheme Charge Transfer, Zihan Mao, Xuan Ran, Shu Lin, Kezhen Qi

Sultan Qaboos University Journal For Science

We synthesized Bi2WO6 via a hydrothermal approach and subsequently fabricated a Bi2WO6/g-C3N4 heterojunction through grinding process. The resulting composite demonstrated an impressive photocatalytic production rate of hydrogen peroxide at 4809.5 μ mol g-1 h-1, which is nearly double that of CN and 18 times greater than that of BWO. The photocatalytic effectiveness of the BWO/CN composite was thoroughly investigated under different conditions and environmental factors. This enhancement can be primarily attributed to the efficient separation and migration of photogenerated charge carrier pairs facilitated by the S-scheme heterojunction, along with improved redox capability. Photoluminescence spectroscopy and electrochemical impedance spectroscopy (EIS) were …

Theses and Dissertations

Heterogeneous System on Chips (SoCs) provide a robust platform that can flexibly handle different applications. Their small form factor and low power consumption for their performance have made SoCs an attractive option for space applications. However, SoCs are sensitive to the ionizing radiation found in space. We need to understand how an SoC will behave in the high radiation found in space. This requires us to perform radiation testing of the SoCs on Earth to understand their behavior. The radiation testing and analysis of a heterogeneous SoC is complex as it contains multiple different processing cores, memories, and other system …

From Minimum To Meaningful: A Use Of Force Training Regimen For Rural Police Departments, Joseph Corley

Dissertations, Theses, and Projects

This paper examines how small and rural law enforcement agencies can improve use of force training despite limited staffing, budgets, and training opportunities. Current Minnesota POST Board minimum standards establish baseline requirements but allow significant variation in how agencies develop and deliver training, contributing to inconsistent officer preparedness and skill retention. Drawing on current research in police training, motor skill retention, and scenario based learning, this paper argues that infrequent, skills based training is insufficient for preparing officers to manage dynamic, high risk encounters. The paper proposes an evidence based training regimen centered on two department led use of force …
