The continued logging for hardwood in subtropical rainforests is causing deforestation and the destruction of diverse environmental ecosystems. Synthetic plastics and particle boards containing synthetic binders such as formaldehydes are alternatives to hardwood, both of which are harmful to the environment and human health. To eliminate wood logging, various biomaterials could be used as promising alternatives to wooden materials. Cotton have been shown to be a viable alternative to various types of wood. Binders are essential in the production of composite wood from cotton. Natural, environmentally friendly binders that can economically and technically replace synthetic formaldehydes in particle boards have been sought after by scientists. Almost all identified natural binders are derived from plants. Comparison of the various alternatives reveals that neither alternative has been able to be a complete substitute for synthetic binders for a variety of reasons, including thermal stability and adhesive strength in some cases. There is also a lack of research into glue as a potential alternative, according to the literature. As a result, the goal of thisstudy is to contribute to analyzing this gap by investigating the technological readiness level for an animal-based natural binder that could be used in the production of wood from cotton stalks. This natural animal binder is fabricated in the lab, and itseconomic feasibility is compared to synthetic binders such as formaldehyde and ecofriendly formaldehyde, as well as natural binders such as lignin and cardanol and tannin. The findings indicate that using animal-based alternative binders as a replacement for synthetic binders has a high potential. To confirm the technical feasibility of the animal-based binder, additional research and tests for the physical characteristics of the resulting wood from the binder, such as bonding force, bending strength, and cohesion, would be required. © 2022 IEEE.

Novel Intelligent and Leading Emerging Sciences Conference (NILES)

作者： Mohammad M. Abdel Karim Mohamed M. Abdelrahman Amr Guaily Aerospace Department Faculty of Engineering Cairo University Giza Egypt Mechanical Engineering Program School of Engineering and Applied Sciences Smart Engineering Systems Research Center (SESC) Nile University Giza Egypt

This paper introduces the concept of thermal air braking, which involves heating a portion of the airfoil's upper surface to achieve the braking effect. A 2D Computational Fluid Dynamics (CFD) analysis is conducted using ANSYS Fluent software to study the impact of heating the upper back portion of the top surface of an airfoil. The study compares the results of the heated and non-heated cases for NACA 4415. Different aerodynamic efficiencies are investigated, such as lift coefficient (C L ), drag coefficient (C D ), lift-to-drag coefficient (C L /C D ), and pressure coefficient (C P ). The results are promising since there is an increase in the drag coefficient by 70% and a decrease in the lift coefficient by 5%, achieved by heating the last portion of the airfoil.

Novel Intelligent and Leading Emerging Sciences Conference (NILES)

作者： Mohamed Elshabrawy Osama Khalid Mamdouh Zaki Khaled Fasseh Mahmoud E. Said Faculty of Engineering Cairo University Giza Egypt Mechanical Engineering Program School of Engineering and Applied Sciences Nile University Egypt Smart Engineering Systems Research Center (SESC) Nile University Giza Egypt

In this paper, A numerical model based on the shallow water equations is derived to study the combined effects of wind and progressive gravity waves on surf-zone currents. The wind has temporal and spatial variations. The combined effects of spatially and temporal varying wind and waves on the surf-zone currents are investigated by considering different wave incident angles and wind stresses. Numerical results of the current distribution demonstrate the role of the basin topography, coastal configuration and the combined effect of wave radiation and wind stresses on the surf-zone currents distribution. Also, the water surface elevation emphasizes the role of the pressure gradient force due to the non-penetration condition at the coastal boundary.

Melanoma is the most lethal skin malignancy. Fucoxanthin is a marine carotenoid with significant anticancer activities. Intriguingly, Fucoxanthin's impact on human melanoma remains elusive. Signal Transducer and Activator of Transcription 3 (STAT3) represents a promising target in cancer therapy due to its persistent activation in various cancers, including melanoma. Herein, we revealed that Fucoxanthin is cytotoxic to human melanoma cell lines A2758 and A375 while showing limited cytotoxicity to normal human melanocytes. Apoptosis is a primary reason for Fucoxanthin's melanoma cytotoxicity, as the pan-caspase inhibitor z-VAD-fmk drastically abrogated Fucoxanthin-elicited clonogenicity blockage. Besides, Fucoxanthin downregulated tyrosine 705-phosphorylated STAT3 (p-STAT3 (Y705)), either inherently present in melanoma cells or inducible by interleukin 6 (IL-6) stimulation. Notably, ectopic expression of STAT3-C, a dominant-active STAT3 mutant, abolished Fucoxanthin-elicited melanoma cell apoptosis and clonogenicity inhibition, supporting the pivotal role of STAT3 blockage in Fucoxanthin's melanoma cytotoxicity. Moreover, Fucoxanthin lowered BCL-xL levels by blocking STAT3 activation, while ectopic BCL-xL expression rescued melanoma cells from Fucoxanthin-induced killing. Lastly, Fucoxanthin was found to diminish the levels of JAK2 with dual phosphorylation at tyrosine residues 1007 and 1008 in melanoma cells, suggesting that Fucoxanthin impairs STAT3 signaling by blocking JAK2 activation. Collectively, we present the first evidence that Fucoxanthin is cytotoxic selectively against human melanoma cells while sparing normal melanocytes. Mechanistically, Fucoxanthin targets the JAK2/STAT3/BCL-xL antiapoptotic axis to provoke melanoma cell death. This discovery implicates the potential application of Fucoxanthin as a chemopreventive or therapeutic strategy for melanoma management. © 2024 Wiley Periodicals LLC.

The Centrifugal Nuclear Thermal Rocket (CNTR) is a Nuclear Thermal Propulsion (NTP) concept designed to heat propellant directly by the reactor fuel. The primary difference between the CNTR concept and traditional NTP systems is that rather than using traditional solid fuel elements, the CNTR uses liquid fuel with the liquid contained in rotating cylinders by centrifugal force. If the concept can be successfully realized, the CNTR would have a high specific impulse (up to 1800 s) at high thrust, which may enable (i) viable near-term human Mars exploration by reducing round-trip times to 420 days and (ii) direct injection orbits for scientific rendezvous missions to the Solar System outer planets and Kuiper Belt objects. research is presently underway to determine resolutions for the significant engineering challenges that the CNTR concept presents. These challenges, the study plans to address them, and progress have been described previously;this paper provides an update on progress to date for the overall research effort, including strategies and key results on revision of a reference configuration, definition of key parameters which allows integration of the results of various analyses, and reviews strategies to mitigate the problem of Uranium vapor saturating the propellant exhaust and significantly impacting the CNTR’s specific impulse. Analyses and experiments, both underway and planned, to update estimates of engine key performance parameters including specific impulse, thrust and thrust to weight ratio along with the identification of selected design margins within the engine itself are described – all toward the goal of enabling plans for a laboratory demonstration of a single Centrifugal Fuel Element. © 2025, American Institute of Aeronautics and Astronautics Inc, AIAA.

In recent years, rapid digitization and technological advances have enabled governments and companies to utilize various types of personal information, including environment, medical, and lifestyle. Privacy protection is an important issue in the utilization of personal information, and anonymization methods such as k-anonymization and 1-diversity have been proposed in the past. However, to utilize data effectively, it is also important not to lose the usefulness of the information. Privacy protection and preserving the usefulness of information are in a trade-off relationship, and balancing these two aspects has been a difficult problem. Recently, microaggregation using clustering algorithms has been attracting attention as an anonymization method that ensures the usefulness of the data while protecting privacy. In this study, we proposed a new microaggregation method based on iterative processing using probabilistic latent semantic analysis and evaluated the proposed method based on the use case. The use case is a classification of social isolation and an analysis of the relationship with physical frailty risk using the classified groups. Compared to microaggregation using quasi-identifiers and microaggregation based on a conventional clustering algorithm, the proposed method was able to find social isolation characteristics obtained in the raw data with higher accuracy. In addition, in a more detailed analysis focusing on a population with certain characteristics, the proposed method was able to replicate the analysis results obtained using the raw data and to make appropriate assessments of the health risks. © 2023 IEEE.

Nursing information systems are becoming increasingly prevalent in our medical institutions. However, changes in the social environment and imbalances between the demands of caregivers and care recipients mean that current nursing information systems are inadequate in terms of quality and operational needs. This article was written to provide insights into opportunities to leverage technology to further promote care quality by applying a "data, information, knowledge, and wisdom" system development structure to develop intelligent technology products that equitably meet the needs of patients, caregivers, and nursing processes. Applied in clinical settings, these products should help satisfy patient needs and facilitate nursing work.

Dynamics of an EV Charging Station considering Queuing Theory

引用

Transportation research Procedia 2025年 84卷 434-439页

作者： Hasan Masrur Ali T. Al-Awami Industrial and Systems Engineering Department King Fahd University of Petroleum and Minerals Dhahran 31261 Saudi Arabia Interdisciplinary Research Center for Smart Mobility and Logistics King Fahd University of Petroleum and Minerals Dhahran 31261 Saudi Arabia Electrical Engineering Department King Fahd University of Petroleum and Minerals Dhahran 31261 Saudi Arabia

This research introduces a queuing framework, denoted as M1/M2/c, to analyze the dynamics of electric vehicle (EV) charging stations. The framework considers non-uniform Poisson arrival rates (M1), influenced by road traffic conditions, and exponential service durations (M2), affected by factors such as battery size and charging habits. The variable ”c” represents the number of chargers at the station. Using this framework, the study evaluates the charging demand and capacity of a single EV charging station. Results indicate that the station’s capacity to simultaneously charge EVs is limited, despite varying arrival rates and charging durations. Additionally, the projected charging demand follows a similar trend to EV arrival rates, peaking during daytime hours. Overall, the study provides insights into managing EV charging infrastructure amidst fluctuating demand and limited capacity.
