Kinetic Study Of Oil–Water Separation In A Dual Port Inlet Cyclone Separator, Ikhwanul Qiram, Agung Nugroho

Journal of Mechanical Engineering Science and Technology (JMEST)

In this study, a Computational Fluid Dynamics method is used to investigate the oil–water separation kinetics in a dual-port inlet cyclone separator. This was achieved using the Reynolds Stress Model coupled to an Eulerian multiphase framework. Three Reynolds numbers were studied (Re = 1.41×10⁵, 1.94×10⁵ and 2.52×10⁵) to analyse the flow; axial velocity distribution, vortex stability, radial migration velocity and separation efficiency were examined individually. Results indicate that both the radial migration velocity (vᵣ) and separation probability (p_remove) grow with Reynolds number, especially for larger oil droplets (10–100 µm). The best condition concerned is that …

Developing A Durable, Memory-Driven, Cspz-Targeting Lyme Disease Vaccine By Rationale Adjuvant Selection\, Miranda Mccarty, Sergio A Hernández, Jill Malfetano, Ana Carolina Leão, Maria Jose Villar, Xiuli Yang, Yi-Lin Chen, Jungsoon Lee, Zhuyun Liu, Ulrich Strych, Maria Elena Bottazzi, Utpal Pal, Klemen Strle, Wen-Hsiang Chen, Yi-Pin Lin

Faculty, Staff and Students Publications

Rational adjuvant selection is a systematic approach based on adjuvant-mediated immunomodulation to identify safe vaccine regimens that enhance protective immunity. Transmitted through ticks and caused by the bacterium Borrelia burgdorferi (Bb), Lyme disease (LD) is the most common vector-borne disease in the Northern hemisphere. There are no approved human vaccines, making it suitable for testing the concept of rational adjuvant selection. Here, we formulated our previously developed and effective LD vaccine antigen, CspZ-YAC187S, with different adjuvants suitable for human use; we analyzed the immune response by transcriptomics and tested the vaccine efficacy after Bb infection. We identified Alum-CpG and Alum-αGal …

Wanted: More Feminist Queer Medievalists In Tolkien Scholarship, Robin A. Reid

Journal of Tolkien Research

J.R.R. Tolkien’s fiction has been identified with the medieval world, and with medieval studies, from the beginning. In this presentation, I acknowledge the extent to which Tolkien scholarship is indebted to the medievalists who established the cornerstone upon which we have all built. Current publications in queer approaches to Tolkien and feminist approaches are growing, but queer scholarship tends to focus on male characters and feminist scholarship on (straight) female characters. What is currently missing in Tolkien scholarship, based on the bibliographic scholarship I have done in the past ten years, is work by feminist queer medievalist scholars and scholarship. …

Variations In Moral Decision Making: In Morally Ambiguous Scenarios, Riley N. Eaton, Victoria Kempton, Edward Lansing, Troy R. Welker

Aurora

People are tasked with making decisions that often come with consequences, whether it be for someone else or themselves. Due to this, there is an ambiguity in understanding what is “right” and “wrong” in a given scenario. However, limited research has examined how interpersonal relationships and intensity of the punishment may affect this decision-making process. This study examines the effect of interpersonal closeness and punishment intensity on moral decision-making, defined in terms of fairness and empathy. Participants (N = 54) from a midwestern university were randomly assigned to one of three interpersonal closeness conditions (close friend vs. close friend, close …

Electrode Coating Methods For Water Treatment: A Comprehensive Review And Comparative Analysis, Noor H. Hamza, Zainab Y. Shnain, Mohammad F. Abid, Ali A. Yahya

Engineering and Technology Journal

Electrochemical water treatment technologies have emerged as highly efficient strategies for environmental remediation, yet their large-scale implementation remains constrained by electrode performance and longevity.

The techniques generate a personal significance score (PSS) normalized to the range (0.0, 1.0) leverage user behavior with reference …

Practitioners’ Experiences Of Developmental, Individual Differences, Relationship-Based (Dir) Approach In Their Professional Practice With Neurodivergent Clients: A Hermeneutic Phenomenological Study, Ekaterina Sidor

Educational Studies Dissertations

This phenomenological study explores how professionals experience integrating the developmental, individual-differences, and relationship-based (DIR) framework in their work with neurodivergent clients. Although DIR is recognized as an evidence-based developmental approach in the field of autism support, little is known about how its integration affects practitioners themselves. Grounded in relational-cultural theory and transformative learning theory, the study examines how engagement with DIR influences practitioners’ professional practice and development. Using a qualitative, hermeneutic phenomenological design, data were collected through open-ended questionnaires and in-depth interviews with multidisciplinary professionals from diverse international contexts who completed DIRFloortime training and actively implement DIR in their work. …

Enacting Leadership And Transforming The World: Hannah Arendt, The Private, The Public, And Transfigurations In Between, Xochitl Mendez

Educational Studies Dissertations

In this dissertation I propose a framework that emphasizes transitions between Private and Public. I argue that individuals can consciously reshape and reformulate these transitions to assert themselves in the world. How can the individual’s own internal realities, ventures, projects and selfhood assert themselves in a fraught world as an act of self-affirmation, leadership, and transformation? New approaches to this question can all be revealed by using transitions between Private and Public as actionable strategies. I re-interpret Hannah Arendt’s Private and Public as she presented them in The Human Condition (1958). I turn these into multivalent and multilayered spaces of …

U.S. V. Washington: Considering The Continuing Injunction Of The Boldt Decision, Nicholas Brown

Public Land & Resources Law Review

Judge George Hugo Boldt’s 1974 opinion in United States v. Washington was a landmark decision in the recognition of treaty fishing rights for tribes in western Washington. Not only did it recognize the entitlement to 50% of harvestable yields of fish within the tribes’ usual and accustomed fishing sites, but it also provided a permanent injunction to protect future fishing rights for generations to come. Now, over fifty years since the original “Boldt decision” was made, judges in the Ninth Circuit are debating whether the continued injunction to litigate intertribal disputes over treaty fishing rights is proper. This article considers …

Western Watersheds Project V. Schultz, Cv 22-149-M-Dlc-Kld, 2025 Lx 449507, 2025 Wl 2410283 (D. Mont. Mar. 27, 2025), Luke A. Zagar

Public Land & Resources Law Review

Western Watersheds Project v. Schultz delineates what the Forest Service is required to consider for revising Allotment Management Plans as prescribed by NEPA. Environmental plaintiffs sued, arguing that the Forest Service’s reliance on an older baseline assessment was arbitrary and capricious and that the revised AMP failed to consider major impacts on the grizzly bear population. The District of Montana held that the reliance on an older baseline assessment was acceptable but simultaneously found the AMP to be arbitrary and capricious under the “hard look” standard.

The tidewater goby and California red-legged frog, both listed species, are also present in Arroyo Grande Creek. The Ninth Circuit determined the …

Unleashing Consultation: Tohono O’Odham Nation V. Department Of Interior And The Case For Reforming The National Historic Preservation Act, Elizabeth Tobey

Public Land & Resources Law Review

The Ninth Circuit’s 2025 decision in Tohono O’odham Nation v. Department of Interior highlights an ongoing failure by federal land management agencies to consult meaningfully with tribal nations as mandated by the 1966 National Historic Preservation Act. This article argues that the NHPA’s framework for tribal consultation enables federal land management agencies to sidestep meaningful engagement with tribes, undermining both cultural resource protection and the federal Indian trust responsibility. To address these deficiencies—particularly in the context of renewable energy development on federal public lands, directly at issue in Tohono O’odham Nation—this article proposes amendments to the NHPA informed by …

Wilderness Watch V. U.S. Forest Service, No. Cv 23-133-M-Dwm, 2025 Wl 2985292 (D. Mont. Oct. 23, 2025)., Gardner Dee

Public Land & Resources Law Review

This comment argues that the District of Montana’s decision in Wilderness Watch v. U.S. Forest Service correctly applied the Ninth Circuit’s Kofa framework to strike down a multi-agency native trout restoration project in the Absaroka-Beartooth Wilderness, holding that the Forest Service unlawfully prioritized Yellowstone cutthroat trout conservation over the Wilderness Act’s mandate to preserve wilderness character. Dee further contends that while large wilderness watersheds offer valuable climate refugia for native coldwater fish, watershed-scale restoration projects will continue to conflict with the Act’s prohibitions on motorized and mechanized intrusions so long as agencies rely on helicopter transport and rotenone application at …

Oxidized Lipids Are Inflammatory Danger Signals. The Hydrolytic Enzyme Carboxylesterase 1 Regulates Their Metabolic Fate, Thereby Shaping Macrophage Phenotype., Oluwabori Adekanye

Theses and Dissertations

Macrophages originate from hematopoietic progenitors they are immune cells, part of innate immunity. They patrol tissues to identify damage-associated molecular patterns (DAMPs) and pathogen-associated molecular patterns (PAMPs) from microorganisms. Macrophage pattern recognition receptors (PRRs) detect these signals, and respond by secreting lipid mediators, cytokines, and chemokines, thereby initiating the inflammatory response. Carboxylesterases (CES) belong to the α/β-hydrolase fold family of proteins and catalyze the hydrolysis of ester-containing substrates into alcohols and carboxylic acids. CES1 is one of the six CES identified in the human genome. They are localized in the endoplasmic reticulum lumen and cytosol of cells, primarily expressed in …

The Extraction And Chemical Characterization Of The Avian Pigments Turacin And Turacoverdin, Sarah R. Bekkali

Honors Scholar Theses

Bird coloration is a trait that extends beyond mere aesthetics as it has an extensive range of biological significance. Plumage patterns and hues can influence camouflage, mate choice, social dominance, and physiological performance. Bird fitness, their ability to survive and reproduce, is greatly dependent on color. Melanins, carotenoids, and pterins are well-studied pigment systems that are commonly found across many avian species’. Alternatively, porphyrin-based pigments are rare and less-studied as they only found in turacos a sub-Saharan African bird belonging to the family Musophagidae. This thesis focuses on two pigments of interest: turacin, the deep crimson-red pigment found in …
