Stratified Multi-Well Pumping Tests And Back-Analysis Of Hydraulic Conductivity In Ultra-Deep Circular Foundation Pits, Luo Renkun, Wang Jie

Journal of China & Foreign Highway

Dewatering prior to foundation pit excavation is a critical measure to prevent engineering hazards such as slope instability at the pit top, seepage around the pit, and bottom heave. As a key parameter in dewatering design, hydraulic conductivity directly influences the risk control in foundation pit engineering. Based on the east anchor foundation pit project of the Shiziyang Passageway, single-well pumping tests and stratified multi-well pumping tests were conducted. The water level variations in the internal dewatering wells and the external observation wells were monitored in stages. Accordingly, a finite difference numerical model for the pumping tests was established. The …

Characteristic Analysis Of Detection Profiles For Internal Moisture Content Of Asphalt Pavements Based On Ground Penetrating Radar, Yang Li, He Pingping, Liu Weizhen, Fu An

Journal of China & Foreign Highway

As a novel non-destructive testing method for roads, ground penetrating radar (GPR) can effectively prevent road water damage by regularly detecting the internal moisture condition of roads. However, when the moisture data of GPR are analyzed, the moisture conditions obtained by relying solely on the analysis of a single profile characteristic may be misjudged. To improve the accuracy and reliability of GPR in detecting the internal moisture content of pavements, focus was placed on the time-frequency domain analysis of GPR moisture content detection profiles in this paper. Simulation tests were conducted, and the influencing factors and results of moisture detection …

Study On Calculation Method For Incremental Launching Based On Nonlinear Analysis, Mo Shanfeng, Huang Cailiang, Qin Hui

Journal of China & Foreign Highway

In view of the shortcomings of traditional incremental launching calculation methods and the assembly construction control of incremental launching beams, an incremental launching calculation method based on nonlinear analysis was proposed in this paper. This method could truly simulate the running state where the incremental launching pier remains stationary, and the beam moves forward. The assembly alignment of all segments of the beam and the real alignment of the beam under specified working conditions could be directly output. The prefabricated alignment of the main beam (i.e., unstressed alignment) did not need to be consistent with the slide alignment. When the …

From Pathology To Ecology: Rethinking Student Well-Being Through Consciousness-Centered Education, Molly Beauregard

Journal of Conscious Evolution

This article revisits a five-year mixed-methods study conducted from 2012 to 2018, involving 207 student participants (n = 207), of an undergraduate sociology course—Consciousness, Creativity, and Identity—that integrated group meditation and mindfulness into a standard curriculum. Earlier analyses interpreted positive outcomes primarily as reductions in stress and improvements in attention among students. This paper reconsiders that interpretation, arguing that such a framing risks locating dysfunction within students rather than the social and cultural environments they inhabit.

Drawing on an ecological perspective, the study reexamines survey, reflection, and interview data documenting changes, not only in affect and attention, …

Walking The Tightrope: The Precautionary Dilemma Of Neutrality And Guidance, Farhan Lakhany

Animal Sentience

Jonathan Birch’s The Edge of Sentience promises a precautionary framework that guides ethical action without taking sides in the disputed metaphysics of consciousness. I argue that it cannot do both. Birch admits “biopsychism” (that all living organisms are conscious) into his "zone of reasonable disagreement," yet his operational criteria exclude plants and unicellular organisms by requiring evidence that biopsychism holds to be irrelevant. This leaves a dilemma. Keeping the “broad” standard preserves neutrality but extends candidacy to all life, guiding nothing; restricting to scientific evidence guides action but is itself the theoretical commitment the framework was meant to avoid.

A Communication-Aware Game-Theoretic Coordination Framework For Distributed Pump Stations In Pipeline Systems, David A. Brattley, Wayne W. Weaver

Michigan Tech Publications

In large-scale fluid transport systems, distributed pump and valve stations must coordinate their operations to prevent overpressure while minimizing energy use and control effort. This paper presents a communication-aware, game-theoretic coordination framework in which stations act as rational agents that iteratively adjust operating setpoints based on locally computed utilities. Existing station-level pressure controllers regulate local pressures and flows, while a slower supervisory negotiation layer governs inter-station coordination using steady-state hydraulic surrogates derived from pump affinity laws and pipeline loss relationships. The proposed framework does not rely on centralized optimization or exhaustive enumeration of strategies. Instead, stations update setpoints sequentially, evaluating …

Faculty, Staff and Students Publications

Retinal organoids represent a promising regenerative strategy for restoring vision in retinal degenerative diseases, but the capacity of host cone bipolar cells in the primate macula to rewire with transplanted photoreceptors has not been established. In this study, we transplanted genome-edited ISL1-/- human retinal organoids lacking ON-bipolar cells into an acute laser-induced macular photoreceptor ablation non-human primate model. Using immunohistochemistry, ultrastructural imaging, and focal macular electroretinography, we demonstrate that host rod and cone bipolar cells actively extend dendrites toward grafted photoreceptors and form synaptic contacts, with evidence of functional signal transmission in a subset of transplanted eyes. Longitudinal, per-eye analyses …

Accounting And Economic System Classification: An Adverse Effect Of The Misconceptualization Of Capital, Henry Zeno Chalu

Business Management Review

This paper discusses the influence of accounting on economic system classification. Particularly, it traces how a misconception of the accounting term ‘capital’ led to a misleading characterization of capitalism and socialism as inherently oppositional economic systems. This misunderstanding stems from neglect of the two complementary modes of thought on which accounting as a science rests: reasoning, which is the conceptual, idealistic dimension, and proving, which is the technical, physicalist dimension. Both modes are integral to the construction of most of the accounting terms used in economics. If an accounting conceptualization had been followed, capitalism and socialism would not …

Industries including food and beverage, paper, textile, paints, chemicals, and pharmaceuticals require substantial thermal energy for heating and drying, and typically rely on coal and natural gas.This study introduces a unique application of a parabolic trough solar thermal system with integrated thermal energy storage, specifically tailored to …

Translating Science Into Evidence-Based Policy For The Protection And Restoration Of Essential Fish Habitat, Olivier Le Pape, Benjamin J. Ciotti, Karen E. Van De Wolfshaar, Rochelle D. Seitz, Julia Friese, David Eggleston, Elliot J. Brown, Rachel M. Turnbull, Filipe Martinho, Adam Waugh, Francisco E. Werner, Kenneth A. Rose

School of Biological and Marine Sciences

Coastal and estuarine ecosystems are vital as essential fish habitat (EFH). Given accelerating climate- and human-driven environmental change, conserving these habitats is increasingly urgent to ensure the sustainability of marine populations and their associated fisheries. This paper examines how scientific knowledge is being used to support management of EFH in the USA, Europe, and elsewhere. We find that while scientific knowledge to identify and quantify important habitats has rapidly increased, the transfer of this knowledge to management practice has been limited and slow, resulting in important habitats being vulnerable to degradation. Through an international review of EFH concepts and their …

Review And Development Of An Explicit Machine Learning Model For Pollutant Gas Solubility In Ionic Liquids As Green Solvents, Amir Dashti, Farid Amirkhani, Mojtaba Raji, John L. Zhou, Ali Altaee, Ali Braytee, Brett Turner, Hossein Ali Khonakdar, Amir Razmjou

Research outputs 2022 to 2026

The increasing release of greenhouse gases (GHGs) like CO₂, CH₄, N₂O, and industrial contaminants (indirect GHGs) such as SO₂ and H₂S has prompted significant global worries due to their role in climate change, air pollution, and harm to the environment. Ionic liquids (ILs) as green solvents have emerged as promising alternatives to traditional solvents because of their minimal volatility, high thermal stability, and adjustable physicochemical characteristics. Yet, limited gas solubility data in ILs is hindering their applications in carbon capture and air pollution control. Machine learning (ML) is a powerful tool for modeling and simulating the solubility of polluting gases …

K3) From Sacred Landscape To Pilgrimage Environment: The Case Of Monte San Giorgio And Mendrisio, Lorenzo Cantoni, Adine Gavazzi

International Religious Tourism and Pilgrimage Conferences

Across Europe, numerous historic pilgrimage landscapes no longer function as dominant religious destinations, yet devotional practices persist in fragmented, latent, or reinterpreted forms. Pilgrimage however appears to be undergoing a process of transformation within postsecular communities, where spiritual meaning coexists with heritage tourism, community identity, and cultural landscape management. Building on religious tourism studies, pilgrimage is understood as mobility toward sacred sites as well as a ritual process embedded in tradition, motivation, and lived experience (Griffin & Raj 2017). Contemporary scholarship emphasises that pilgrimage preserve the experiential and relational practice linking people, landscape and belief systems, while fighting the tourist …
