An Experimental Study On The Yield Strength Of Cement Grout For Grouting In The Limestone Area Of A Coal Seam Floor, Zou Jun, Guo Yan, Gui Herong, Wang Weimin, Chen Zhenlin, Liu Faming, Dai Yanan, Hu Yang, Chen Zengbao, Li Jun, Gao Chuan, Li Heng

Coal Geology & Exploration

Objective and Methods In recent years, regional grouting through ground directional drilling has become the preferred technique for water disaster prevention and control in floor limestones in a coal mining area. In grouting engineering, the diffusion radius of cement grout, which has always received wide attention, is constrained by multiple factors including the shear yield strength (yield strength for short) and specific gravity of cement grout, along with grouting pressure. The diffusion radius in turn influences the implementation effects of on-site grouting engineering. Among its controlling factors, the yield strength of cement grout cannot be tested on site. Given this, …

Application Of Five Seismic Attributes In Natural Fracture Prediction For Deep Coalbed Methane Production Along The Eastern Margin Of The Ordos Basin, Tong Jiangnan, Wang Feng, Zhang Feng, Hou Wei, Li Zhongbai, Ji Liang, Jiang Yanan, Sun Wei

Coal Geology & Exploration

Background Natural fractures serve as both the primary storage space for free gas of deep coalbed methane (CBM) and pathways for hydrocarbon migration. Furthermore, these fractures can enhance the porosity and permeability of strata under the deep, high-pressure condition, significantly amplifying the permeability of coal seams. Therefore, the fine-scale characterization of the planar distribution of natural fractures is crucial to deep CBM production.Objectives and Methods This study investigated the No.8 coal seam in the Carboniferous Benxi Formation within the Daning-Jixian block on the eastern margin of the Ordos Basin. Through offset vector tiles (OVT) domain processing of offshore 3D …

Analyzing Northwest Ohio Industries And Utilizing The Shape Program To Increase Sustainable Practices, Abigail Stucker

Honors Projects

The purpose of this project is to dive deeper into the corporate perspective on sustainability and why manufacturing companies should take action on such an important topic. Is there a true balance for businesses between increasing profits and reducing waste? Why should businesses care about being branded as a sustainable company? What efforts do companies need to take to truly be branded as “sustainable?” These are questions that drove the research and development of this project. After looking into these guiding questions, this project develops a program to help monitor and measure the successful sustainability practices that various Northwest Ohio …

Innovative Machine Learning, Isotopic, And Hydrogeochemical Techniques For Groundwater Analysis In Arid Landscapes In Egypt’S Eastern Desert, Saad Ahmed Mohallel, Hesham Morgan, Ali Elgendy, Surendra Maharjan, Shahryar Fazli, Wenzhao Li, Rejoice Thomas, Hesham El-Askary

Mathematics, Physics, and Computer Science Faculty Articles and Research

Groundwater serves as a lifeline in Egypt’s hyper-arid Eastern Desert, particularly for agricultural and domestic uses. However, a comprehensive understanding of groundwater origin, quality, and recharge dynamics in the region remains limited due to geological complexity, data scarcity, and the high cost of isotopic analysis. This study addresses these challenges by integrating stable isotopes (δ¹⁸O and δ²H), hydrogeochemical parameters, remote sensing, and explainable artificial intelligence (AI) to investigate groundwater dynamics and support sustainable water management strategies. A total of 34 groundwater samples were collected from three key aquifers: the Quaternary alluvium, Nubian Sandstone, and fractured Basement aquifers. Hydrochemical analyses and …

08 - Blue Carbon Sequestration And Sediment Storage In Seagrass Meadows Of South Bay, Luke C. Clements, Adriana Amrhein, Richard P. Hale

Undergraduate Research Symposium

Blue carbon is stored in coastal and marine ecosystems like seagrass meadows and salt marshes, which helps combat climate change by preventing greenhouse gas emissions. This study examines the role of seagrass in carbon storage by comparing sediment cores from a mud channel and a seagrass meadow in South Bay.

We collected a 100 cm core from the mud channel and a 55 cm core from the seagrass area, taking samples every 10 cm to analyze grain size and organic carbon content. Using a wet sieving method, we separated sand from mud and measured organic carbon through loss on ignition. …

To Infinity And Beyond (And Beyond): The Legal And Ethical Imperative For Rocket Reusability, Matthew Lumia

Duke Law & Technology Review

Although the Space Shuttle’s first flight was in the 1980s, reusable rocket technology did not achieve mainstream viability until SpaceX’s reusable Falcon 9 rocket revolutionized access to space. This note argues that transitioning to reusable rocket technology is not only a practical and economic advancement, but also a legal and ethical imperative. By analyzing reusable rockets through the “due regard” framework of the Outer Space Treaty, this note demonstrates how reusable rockets mitigate space debris, expand access to space, and can reduce environmental harm. Additionally, reusable rockets address critical ethical concerns by lowering barriers to space exploration, allowing the benefits …

Turning Farm Waste Into Energy: Pragmatic Approaches For Cleaner Midwestern American Communities, Rebecca Gaisie

Selected or Submitted Student Research Papers/Projects

Mismanagement of farm waste in the Midwest of the United States has resulted in significant methane emissions, water contamination, and public health concerns. The present manure management rules are still inconsistent, underfunded, and insufficient to motivate individuals to behave in a way that benefits the environment, despite increasing concerns about the environment. This policy study investigates anaerobic digestion as a potential means to convert waste into energy that could support rural and environmental development. Some of the problems with the federal and state legislation examined in this study under an EPI framework are a lack of incentives, inadequate technical support, …
