Editorial: Advances In Ecological Environment Changes In Coastal And Estuarine Waters In Response To Hydrodynamic Variability, Jiayi Pan, Yeqiang Shu, Zhe-Wen Zheng, Adam T. Devlin, Majid Nazeer, Andrew M. Fischer

Civil and Environmental Engineering Faculty Publications and Presentations

Over the past few decades, coastal and estuarine ecological environments have undergone significant and rapid transformations, driven by a range of factors, with the variability in hydrodynamic conditions being one of the most prominent (Elliott et al., 2019; Statham, 2012; Da et al., 2024). These dynamic forces influence water movement, sediment transport, and nutrient cycling, all of which are critical components affecting the health and stability of these ecosystems (van Vliet et al., 2023; Li et al., 2023). Consequently, understanding and interpreting hydrodynamic processes in coastal and estuarine waters are fundamental to unraveling the mechanisms behind ecological changes. This task …

Assessing The Effects Of Dasatinib On Mesenchymal Stem/Stromal Cells, David P. Heinrichs, Vitali Maldonado, I Kade Karisma Gita Ardana, Ryan M. Porter, Rebekah M. Samsonraj

Biomedical Engineering Faculty Publications and Presentations

Introduction

Progressive aging, or senescence, of mesenchymal stem/stromal cells (MSCs) is a major obstacle faced when trying to culture potent stem cells for use in therapy. Senescent cells are irreversibly nondividing cells that cease performing critical functional effects. Elimination of senescent cells using biochemical means, such as the use of senolytic drugs like dasatinib, may be useful in retaining the viable and proliferating populations of the cells.

Methods

An in vitro approach was used to investigate the effect of dasatinib on phenotypic, genotypic, and immunomodulatory functionality of osteogenic and adipogenic differentiated MSCs. Replicative senescence was achieved through multiple sub-culturing in …

Joint Modeling Of Degradation Signals And Time-To-Event Data For The Prediction Of Remaining Useful Life, Sebastian Brumm, Erik Linstead, Junde Chen, Narayanaswamy Balakrishnan, Yuxin Wen

Engineering Faculty Articles and Research

Accurate prediction of remaining useful life (RUL) for in-service systems plays an important role in ensuring efficient operation of industrial equipment and in preventing unexpected equipment failures. In this paper, we present a prognostic framework for real-time RUL prediction based on joint modeling of both degradation signals and time-to-event data. The proposed model employs a change point-based general path model to capture signal non-linearity and Neural network (NN) based Cox model to link the time-to-event data with the estimated degradation trend. An empirical two-step scheme for hyperparameter estimation is proposed to enhance prognostic accuracy. Furthermore, an efficient Bayesian model updating …

Highly Sensitive Detection Of Strontium Ions Using Metal-Organic Frameworks Functionalized Solid-State Nanochannels, Xu-Gang Wang, Zheng-Xu He, De-Fang Ding, Xue-Qin Luo, Li Dai, Wei-Qi Zhang, Qun Ma, Yu Huang, Fan Xia

Journal of Electrochemistry

Strontium-90, a highly radioactive isotope, accumulates within the food chain and skeletal structure, posing significant risks to human health. There is a critical need for a sensitive detection strategy for Strontium-90 in complex environmental samples. Here, solid-state nanochannels, modified with metal-organic frameworks (MOF) and specific aptamers, were engineered for highly sensitive detection of strontium ion (Sr²⁺). The synergistic effect between the reduced effective diameter of the nanochannels due to MOF and the specific binding of Sr²⁺ by aptamers amplifies the difference in ionic current signals, enhancing detection sensitivity significantly. The MOF-modified nanochannels exhibit highly sensitive detection of …

Water Quality Standards Assessment, Using Epanet Modeling– Prishtina Case – Oxidation-Reduction Of Manganese On Dw Network, Sokol Xhafa

UBT International Conference

Thermal stratification and water movement in reservoirs are key natural processes. While most effects of this movement are beneficial, such as increased oxygen levels, the presence of manganese (Mn) poses a challenge. During autumn, water circulation causes manganese to shift from its solid Mn(4+) form to the dissolved Mn(2+) form, preventing sedimentation and leading to issues in water treatment and distribution networks. This report focuses on these challenges at the Badovc Reservoir, near Prishtina, Kosovo. Built in 1965, Badovc is one of the oldest reservoirs in the country. Manganese, while usually an aesthetic issue that can cause "black water," can …

Analysis Of Bicycle Network Infrastructure - Example Of Gjakova Municipality, Beni Kizolli, Florin Halili

UBT International Conference

Asphalt During the war (1998-1997), the municipality of Gjakova suffered great destruction, especially in terms of construction and infrastructure. Since that time, the demand for new constructions and reconstructions of old residential houses as well as road infrastructure was increasing. The development of the construction and infrastructure sector has also influenced the increase in the number of employees in this sector. Due to the lack of experience in this field, many professional and complex problems have been encountered both in the field of infrastructure and in the field of traffic regulation. The formation of the state of Kosovo (1999-2007), initially …

Self-Healing Concrete (Shc): A Systematic Literature Review Of Environmental Benefits And Applications (2019-2023), Visar Hoxha, Hyrmete Baca Gashi, Veli Lecaj, Fuat Pallaska, Hazer Dana, Jehona Hoxha

UBT International Conference

This research aimed to provide a comprehensive understanding of the environmental implications of self-healing concrete (SHC) through a systematic literature review. Adopting the methodological framework proposed by Tranfield et al. (2003), the study consolidated fragmented knowledge across the domain. Data collection was executed using Google Scholar, targeting articles from 2019 to 2023, resulting in an initial pool of 60 potential articles. Rigorous screening narrowed this to 17 articles that were critically analyzed for patterns, consistencies, and discrepancies, inspired by Yin's (1994) approach. The synthesis stage generated new insights, framing them into a coherent narrative on SHC's environmental impact. Notably, while …

Organic Amendments Improve The Quality Of Coal Gob Spoils: A Sustainable Mining Waste Reclamation Method, Zhiming Zhang, Anshuman Satpathy, Kirby Morris, Abhishek Roychowdhury, Rupali Datta, Dibyendu Sarkar

Henry M. Rowan College of Engineering Departmental Research

Coal mine tailings can lead to a range of environmental problems, including toxic metal contamination, soil erosion, acid mine drainage, and increased salinity. Mine spoils from coal mining activities accumulated as gob piles are difficult to reclaim due to constraints such as a steep slope, unsuitable pH, insufficient nutrient supply, metal toxicity, low water-holding capacity, and poor soil structure. We investigated the efficiency of low-cost amendments on coal gob spoils from Carthage Coal Field (CCF) in New Mexico in improving the quality of coal gob spoils. Gob spoil was incubated for 90 days with various rates of organic amendments such …

Numerical Simulation Of Gas Flow In A Direct-Flow Cyclone, V.S. Toptalov, S.U. Ganieva, O.M. Flisyuk, Kh.S. Nurmukhamedov

Chemical Technology, Control and Management

A numerical model of gas flow in a direct-flow cyclone of two different configurations is presented. The main task of the simulation was to determine the gas velocity field in the apparatus and analyze the presence of a turbulent wake of the stabilizer swirled, which can have a negative impact on the efficiency of the apparatus. During the study, it was found that when the gas flow is disrupted by the stabilizer of the swirler, a turbulent wake is formed, into which trapped particles can fall. The solution to this problem is to lengthen the stabilizer and increase its diameter. …
