A Rigorous Framework For An Improved Messinger/Myers Model Of Ice Accretion Under Conditions Of Variable Property And Unsteady Aircraft Icing, Hashnayne Ahmed, Arash Shad, ‪Nadim Zgheib, S. A. Sherif, S. Balachandar

Mechanical Engineering Faculty Publications

We analyse the Messinger/Myers model by critically evaluating simplifying assumptions through a rigorous formulation of the rime ice accretion process. We explore the effects of both constant and variable ice density and thermal conductivity, along with the effects of sublimation from the ice surface. The effects of key factors such as droplet impact rate, ambient temperature relative to the freezing temperature and the temperature difference between the ambient air and the airfoil surface are examined. Under these varying conditions, the present rigorous formulation is used to assess the significance of unsteady effects, variable ice properties and sublimation. We observe that …

Microbial Nanocellulose Based Biocomposites For Soft Bone Regeneration: From Present To The Future: From The Present To The Future, Probal Basu, Nabanita Saha, Tomáš Sáha, Petr Sáha

Research Outputs: 2025-Present

Microbial nanocellulose (MC) draws special attention from the research community due to its unique nano-bio fabrication. This nanofiber-constructed biomaterial is biosynthesized by certain microbes in the purest form (devoid of lignin, pectin, and hemicellulose). Due to its striking similarities to animal collagen fibers, MC nanofibers have been used to develop osteoconductive biomaterial for soft tissue regeneration. High surface area, notable rheological properties, and biocompatibility make this material attractive for tissue regeneration. Concurrently, their bio-friendly characteristics are due to various bio-ceramic materials like calcium phosphate (CP) employed in conjunction with MC (for the development of scaffold/bio-composite). The significant interaction between MC's …

Primary testicular (PT) diffuse large B-cell lymphoma (DLBCL) is a rare and aggressive lymphoma with distinct clinical and molecular characteristics. To identify prognostic biomarkers in PT-DLBCL, in this study we analyzed DNA and RNA samples of PT-DLBCL tumors from 206 patients using next-generation sequencing platforms and assays. Genetic alteration analysis found that multiple chromosomal copy number variations (CNVs), TP53 transcript mutations with high variant allele frequency, and MCD subtype had significantly adverse prognostic effects, whereas elevated microsatellite instability had a significantly favorable prognostic effect in PT-DLBCL. Targeted RNA-seq analysis identified a PTL gene expression signature by comparing PT-DLBCL with systemic …

In this study, we compiled 11 records of winter breeding long-eared owls from northwest and central Türkiye, based on our field observations and data from rehabilitation centers. The estimated …

Green Infrastructure Features And Benefits Communicated By Programs Targeting Residents In The Greater Toronto Area, Nya Lazarus-Munnick, Tenley M. Conway

Cities and the Environment (CATE)

Municipalities are increasingly adopting green infrastructure (GI) as a nature-based solution to address stormwater management, climate adaptation, and other urban environmental challenges. One of the strengths of GI is its multifunctionality, which can provide a range of social, economic and environmental benefits. For GI to reach its full potential, widespread implementation throughout a landscape is needed. As a result, GI strategies often rely on various actors, including residents, who can implement GI on their own properties and contribute to the scaling up of GI across a landscape. GI implementation that depends on residents, however, has many challenges pertaining to their …

Computational Thinking As A Novel Framework For Enhancing Cognitive Organization In Older Adults With Cognitive Frailty (Letter To The Editor), Daisuke Akiba

Publications and Research

As aging populations grow, especially in high-income nations, the burden of dementia-related care continues to escalate both economically and socially. In response, this article introduces Computational Thinking (CT) as a novel, non-pharmacological framework to support cognitive organization in older adults experiencing cognitive frailty. Though CT has gained traction in fields like PK-16 education, including special education, for enhancing executive function and problem-solving, it has not yet been applied to geriatric- or memory-care contexts. This perspective proposes that CT’s core components (i.e., decomposition, pattern recognition, abstraction, and algorithmic thinking) may align with residual cognitive strengths in mild-to-moderate dementia, offering a strengths-based, …

Machine Learning Modeling Approaches For Predicting The Extent Of Fatigue Damage In Polycrystalline Alloy Structures, Hassan Alqahtani

Yanbu Journal of Engineering and Science

Using predictions of crack-tip-opening-displacement (CTOD) to measure the extent of fatigue damage has provided the opportunity to prepare an efficient strategy for protecting mechanical structures from damage and developing a structural health monitoring system. The objective is to forecast non-measurable CTOD by using machine learning methods. In this paper, an optical metrology device, which is built by Alicona on a confocal microscope and hereafter referred to as Confocal Microscope, has been used to measure CTOD. However, two factors limit the usage of Alicona Apparatus: (i) the size of optical images, where a CTOD over 400 micrometers cannot be measured; and …

Finding High Mass X-Ray Binaries In Ngc 3109, Caeden Miller, John (Jay) Gallagher Iii

Macalester Journal of Physics and Astronomy

High Mass X-Ray Binary systems can be difficult to find in the Milky Way due to high metallicity contributing to mass loss due to stellar wind, so we turn our attention to the galaxy NGC 3109 in order to find these systems. Using archival data from the Hubble Space Telescope using the Wide Field Camera 3, we do photometry in both the F475W and F814W filters for the two fields of view that cover the galaxy. We then plot these magnitudes on a color-magnitude diagram and use isochrones of 5 and 10 million years to gather minimum mass estimates of …

Non-Destructive Compositional Analysis Of Lead Halide Perovskite Films Using Thz Spectroscopy And A Three-Oscillator Dielectric Model, Isaac J.C Kisker

Macalester Journal of Physics and Astronomy

Terahertz (THz) Spectroscopy offers a novel approach to probing low-energy phonon excitation in complex crystalline materials like methylammonium lead iodide (MAPI) perovskite films. In this research, we use time-resolved Terahertz Spectroscopy in tandem with a three-oscillator model to non-destructively ascertain the relative volumetric composition of MAPI and residual lead iodide (PbI₂) in spin-coated films. The dielectric function is modeled as a product over longitudinal and transverse optical phonon modes. This model is then fitted to the measured THz spectra, allowing us to extract the contributions from both MAPI and PbI₂.

Monitoring The Degradation Of Methylammonium Lead Iodide Perovskite Thin Films By Uv Exposure, Addison Dau, Ethan Dale, James Heyman

Macalester Journal of Physics and Astronomy

This project involved lead-halide perovskite thin films, a promising novel solar cell material. The goal was to monitor the composition of the samples during degradation from blue light exposure using vibrational spectroscopy. IR and THz spectroscopy measured the composition of the samples in-situ between periods of blue light exposure, probing the N-H and Pb-I vibrational modes. Plotting MA and MAPI concentrations versus blue light exposure showed that the MA and MAPI concentrations initially decreased in a gradual linear fashion until a threshold photon flux where both vibrational absorption bands simultaneously collapsed. This suggests that there is a discontinuous change in …

The Bond Of Peace: Restoring Souls In Worship Amid Culture War And Moral Suffering, Steve Yeagley

Andrews University Seminary Studies (AUSS)

Jeremiah’s critique of war as false worship challenges popular Christianity’s support of American war culture. While primarily expressed as American militarism, war culture also manifests in the rhetoric of culture wars. Adding to the division and violence that the nation’s culture wars can fuel is their potential to inflict moral suffering. Emerging discourses of moral distress and injury suggest that, like wartime environments, culture wars may exact a spiritual toll. Unlike the militant liturgies of war culture, Christian worship can address this moral suffering. When acknowledged in worship through witness and lamentation, moral distress and injury offer a prophetic critique, …
