A disease is a distinct abnormal state that significantly affects the functioning of all or part of an individual and is not caused by external harm. Diseases are frequently understood as medical conditions connected with distinct indications and symptoms. According to a fairly wide categorization, diseases can also be categorized as mental disorders, deficient diseases, genetic diseases, degenerative diseases, self-inflicted diseases, infectious diseases, non-infectious diseases, social diseases, and physical diseases. Prevention of the diseases is of multiple instances. Primary prevention seeks to prevent illness or harm before it ever happens. Secondary prevention tries to lessen the effect of an illness or damage that has already happened. This is done through diagnosing and treating illness or injury as soon as feasible to stop or delay its course, supporting personal ways to avoid recurrence or reinjury, and implementing programs to restore individuals to their previous health and function to prevent long-term difficulties. Tertiary prevention tries to lessen the impact of a continuing sickness or injury that has enduring repercussions. Diagnosis of the disease at an earlier stage is important for the treatment of the disease. Hence, in this study, deep learning algorithms, such as VGG16, EfficientNetB4, and ResNet, are utilized to diagnose various diseases, such as Alzheimer's, brain tumors, skin diseases, and lung diseases. Chest X-rays, MRI scans, CT scans, and skin lesions are used to diagnose the mentioned diseases. Transfer learning algorithms, such as VGG16, VGG19, ResNet, InceptionV3, and EfficientNetB4, are utilized to categorize various diseases. EfficientNetB4 with the learning rate annealing, having obtained an accuracy of 94.04% on the test dataset, is observed. As a consequence, we observed that every network has unique particular skills on the multi-disease dataset, which includes chest X-rays, MRI scans, etc., © The Author(s) 2024.

Hybrid aluminium matrix composites through stir casting were made and their mechanical properties are evaluated in this research paper. To strengthen Al7068 hybrid aluminium matrix composites with different SiC weight percentages were created using SiC (0, 2, 4, 6, and 8), coconut shell fly ash (4 wt%) and nano magnesium (2%). Hardness, Impact, ductility and Tensile Strength are just a few of the mechanical properties discussed in this work. Researchers found that adding eight percent SiC reinforcement to aluminium 7068 alloy reinforced with four percent coconut shell fly ash increased the composites' hardness through 32 percent. Adding six percent SiC and four percent coconut shell fly ash to an aluminium alloy 7068 increased its tensile strength by 65 percent. A combination of coconut shell fly ash with Silicon carbide reduced the ductility of the composite material. Aluminium alloy with CSFA and SiC increased the impact energy to 3.2 J. The impact strength increased and decreased in fabricated composites when reinforcement was added to base material. © 2022

引用

Journal of materials engineering and Performance 2025年 1-12页

This study investigates the influence of various process parameters on the quality of oxygen-free copper tubes produced by the Upcast process. Key factors such as the fit between the graphite die and inner tube (ΔD), immersion height of the graphite die into the melt, melt temperature, and water flow rate were analyzed using a comprehensive central composite experimental design. Results show that ΔD, interactions between immersion height and melt temperature, and water flow rate significantly impact the solidification front location (SFL), tensile strength, and grain size. An extremum point at 1160 °C for melt temperature was identified, where SFL initially increases with temperature but decreases beyond this point. A tighter ΔD enhances tensile strength and alters grain size behavior. Optimal parameters for producing high-quality copper tubes were determined: ΔD of − 0.08 mm, water flow rate of 47 L/min, immersion height of 25 cm, and melt temperature of 1161 °C.

Rising levels of atmospheric carbon dioxide (CO2) and methane (CH4) have sparked the interest of researchers in resolving this issue. Various technologies have been utilized such as dry reformation of methane (DRM), that turns these greenhouse gases (GHGs) into syngas. Numerous studies have been done in recent years to produce efficient and competitive catalysts for DRM. However, a "state of the art" review is still required due to a lack of literature on improvements and scalability of robust catalytic systems. This study aims to evaluate recent advancements in catalyst formulations, their activities, stability, and selectivity. We have discussed a variety of materials, including Metal-Organic Frameworks (MOF), a type of two-dimensional transition metal carbides and nitrides (MXene), reducible and irreducible metal oxides, transition metal oxides, zeolites, carbon, and biochar-based catalysts, which are responsible for improving the effectiveness of the DRM process. Furthermore, machine learning (ML) approaches are highlighted for their potential in catalyst design and optimization, providing increased accuracy and efficiency. This review highlights major enhancements to the DRM method, which result in higher hydrogen yield and catalyst stability. Novel catalysts have been created to tackle crucial problems including coking and sintering, which are necessary to progress commercialization. To ensure successful commercial application, future research should concentrate on finding catalysts with excellent features that are also economically viable. This study provides a significant resource for future catalyst development and promotes greater cooperation between academic and commercial communities. © 2024 Hydrogen Energy Publications LLC

The paper employs two methods, pyrolysis and physical crushing, to pretreat discarded photovoltaic modules, dividing the solar cells into "cell particles" and "powder" components. The composition of elements in the cells is determined using SEM-EDS, and a preliminary quantitative analysis of the components of crystalline silicon solar cells is conducted. Dissolution experiments are performed on the pretreated cells, using sodium hydroxide to leach aluminum and dissolve silicon nitride, and using nitric acid to dissolve the carbon in the cells. EDS is used to detect the elemental content after the chemical experiments. The results show that a combined method of pyrolysis and chemical methods achieves a silicon extraction rate of 81.6%, effectively realizing the separation and purification of silicon from used photovoltaic panels. © 2025 SPIE.

Natural fibers have gain a lot of consciousness as potential alternative for the substitution of man-made fibers, as reinforcement of a range of resins for highly developed application as they are having little density, renewable, sustainable, and eco-friendly. Throughout processing, natural fibers are not having any harmful effects and are not coarse to the dispensation apparatus. In this paper hybrid composite by using jute fibre and sisal fibre reinforced with epoxy resin has been prepared and their mechanical properties and dc conductivity have been measured. Measurements have been conducted on the hybrid composites by using Electrometer. It is observed that the hybrid composite having unidirectional orientation of jute fibre and sisal fibre gives better mechanical properties. It was observed that the surface treatment of fibres eliminates some quantity of lignin, wax and oils on both sides of the cell wall of the fibres and the alteration of certain amount of alpha to beta cellulose. Due to these changes there is an improvement in tensile strength of the composites and increase in conductivity was also observed. © 2022

In recent years, several industries have increased their demand for processing precision, automatic detection, and visualization interfaces. Therefore, to keep pace with the fourth industrial revolution, machine tool operators install a large number of sensors on machine tools to obtain more precise physical quantities during processing and use a variety of sensors to obtain measurements in various situations. However, these additional sensors on machine tools result in complicated wire layouts, which exhibit negative effects on processing. Such problems lead to the birth of wireless data transmission, which is expected to become the new standard in the future. At present, there is more and more interactive integration between relevant embedded system and the machine tool, which allows information communication between each other in the wireless domain. However, generally, the majority of machine tool operators focus on optimizing the sensing conditions during processing, but they disregard the importance of information security. In the current era of the Internet of Things (IoT), information security is regarded as a crucial factor. For the wireless communication between the IoT equipment for each machine in the machining field, the transmitted data are almost exposed within public space directly due to the loss in constraint and protection of physical wiring. Therefore, such a process can easily be intercepted by other devices that capture information on relevant status of the machine or command messages received by the controller, where intentional individual may possibly control the operating mechanism and progress of entire plant. This leads to theft of relevant secrets in manufacturing technology for the subject company, or intentional shutdown, machine damage, and vicious blackmailing attacks. Therefore, introducing the mechanism of safety protection during wireless signal transmission is an inevitable technology to maintain the company interests and also the
