Makara Journal of Science

Hypothyroidism, characterized by insufficient thyroid hormone production, affects approximately 5% of the population, especially women, thus increasing pregnancy-related risks. Conventional screening mainly measures thyroid-stimulating hormone (TSH) and free thyroxine (FT4). Detecting the presence of anti-thyroid peroxidase (anti-TPO) antibodies indi-cates autoimmune thyroid disease. This study developed an indirect enzyme-linked immunosorbent assay (ELISA) kit for detecting circulating TPO using polyclonal antibodies generated in rabbits. TPO was isolated from positive sera of pa-tients with hypothyroidism, purified by electroelution, and confirmed as a 52-kDa protein by Western blot. Rabbits immunized with this protein produced polyclonal antibodies with the highest titer (OD = 0.334) at …

Levofloxacin-Ketoprofen Multicomponent Salt Development As A Strategy To Improve The Antibiotic Potency And Anti-Inflammatory Performance, Ilma Nugrahani, Nadhira Dzaky Naushafira, Nova Suliska, Marlia Singgih Wibowo, Hana Fauziah

Makara Journal of Science

Levofloxacin is a fluoroquinolone antibiotic with higher solubility than those from previous generations, but it is light-sensitive. Antibiotics, including levofloxacin, are generally prescribed in combination with nonsteroidal anti-inflamma-tory drugs (NSAIDs) to treat inflammatory infections. Furthermore, NSAIDs have poor water solubility, which can be improved by forming salts or multicomponent systems. This study aimed to develop a multicomponent system from levofloxacin with ketoprofen, an NSAID, and to evaluate its physicochemical characteristics; antibiotic potency; in vivo anti-inflammatory activity; absorption, distribution, metabolism, and excretion (ADME); and in silico toxicity risk. First, a phase diagram was created to predict the interaction type in the …

Not Merely A Workaround: Theorizing Asynchronous Math Talks As A Robust Instructional Routine For Visible Thinking, Participation, And Engagement In Mathematics Teacher Education, Simon Byeonguk Han

Dissertations and Theses

The sudden global shift due to COVID-19 accelerated the need for a better understanding of mathematics learning and teaching in an asynchronous format. Also, despite the popular use of mathematics instructional routines in mathematics classrooms, the field of mathematics education research has very limited empirical studies on instructional routines. This dissertation addresses this by examining Asynchronous Math Talks (AMTs), a structured instructional routine adapted from Number Talks. The central goal of this research is to develop and theorize AMTs not merely as an online workaround, but as a robust instructional model that leverages the unique affordances of digital platforms to …

When Three Points Aren't Enough: Parameter Estimation In Newton's Law Of Cooling, Alberto A. Condori, Cara D. Brooks, Madeline R. Goldberg

CODEE Journal

We begin with a paradoxical three-point problem where the standard parameter estimation formula fails because temperature data must satisfy a concavity condition reflecting Newton's Law of Cooling's exponential structure. Although a closed-form solution for A exists for equally-spaced measurements, high sensitivity to error motivates the use of overdetermined systems with many measurements. The "profiling over A" technique transforms this three-parameter nonlinear problem into a sequence of simple linear regressions, providing computational efficiency and conceptual transparency. This approach can be generalized to many parameter estimation problems in science and engineering, making it a valuable tool for undergraduates interested in applied mathematics. …

Ai In Higher Education: Some Notes From The Front, Debra Rienstra

University Faculty Publications and Creative Works

We’re four weeks into the semester now. This past summer, our university unveiled a campus-wide AI policy that exhorts students and faculty to use discernment and tries to lay out some rules about security. Meanwhile, we have purchased a campus-wide subscription to an AI aggregator tool now available to all students, faculty, and staff (in part, from what I understand, as an attempt to effect some boundaries). And then, in the news, all this hand-wringing over the end of humanity, etc., on the one hand and techno-utopian promises on the other.

The Zero-Point Game℠: A Signed-Balance Reciprocity Ledger With Annual Balance Reset, Non-Convertible Social And Environmental Accounts, And An Ai Coordinator For Routing And Magnitude, Thon Ly

Defensive Publications Series

We specify a signed-balance reciprocity ledger, played as an ongoing non-zero-sum game, in which each recorded kindness posts an equal-and-opposite pair: the giver's balance moves positive and the receiver's negative by the same magnitude, so the sum across participants is zero by construction, and a participant returns toward zero only by passing an imbalance onward. Balances are never a store of value or a claim on goods. Components: (1) a self-directed acknowledgment event whose forwarded half, under a fifty-fifty forwarding rule, is re-issued to another participant, starting circulation without a prior counterparty; (2) two segregated, non-convertible balances per participant, one …

Factors Influencing Non-Perennial Stream Initiation In The Mt. Hood National Forest, Allison Bast

Dissertations and Theses

Historically, non-perennial headwater streams have been overlooked due to their small size and infrequent flow regimes, often leading to them not being recognized as legitimate streams, despite scientific evidence that has shown these streams significantly affect the quality of downstream waters. To combat this issue, environmental managers need to be able to accurately identify and delineate the origins of these streams; however, despite decades of research, an accurate, universal method for predicting how and where these streams commence has yet to be developed. Early studies conducted in steep, humid environments, identified a strong inverse linear relationship between the size of …

Pyrolysis Of Biomass Feedstocks For Hydrogen-Enriched Syngas Production: Cold Gas Efficiency Modelling, Latin Hypercube Uncertainty Analysis, And Parametric Stress Analysis, Hadi Taghavifar, Thomas Allison, Hao Chen, Dibyendu Roy, Abdullah Malik, Yaodong Wang, Anthony Paul Roskilly, K.V. Shivaprasad

School of Engineering, Computing and Mathematics

Biomass-derived syngas offers a viable pathway for producing renewable, hydrogen-rich fuel gas. However, its conversion performance is influenced by feedstock type, temperature, feed rate, and moisture content. This study develops a Cold Gas Efficiency (CGE) model for four agricultural feedstocks: wheat, barley, oilseed rape, and beans. Temperature-dependent regression correlations are developed for the main syngas components and gas flow rate using experimental data. Results show that CGE is highly sensitive to temperature, with low-temperature stress (0–5th percentile) reducing mean CGE by up to 22%. High-moisture stress (95–100th percentile) produced an even larger decline, lowering mean CGE from ∼44% to ∼35% …
