In this research work, the vacuum annealed stainless steel samples were subjected to a constant load. The wear behavior of AISI 431 sample were examined by using pin on disc wear tester. The vacuum annealing were used to preserve the stability between ductility and brittleness. The samples were created in cylindrical shape with a length of 40 mm and diameter 8mm. For this current research, 3 samples are treated at 600°C, 660°C, 820°C temperatures and they were assigned asA1, A2 and A3 respectively. The outcome of vacuum annealing is that to reduce the hardness and increase in ductility, to overcome the material from defects and release internal stress. The hardness, wear behavior were measured for the treated and untreated samples. To evaluate the wear behavior, comparison of results, wear test studies and scanning electronic microscope analysis were done.

The comparative evaluation offered within the paper aligns with the broader theme of sustainable wound care by means of focusing on the efficacy and environmental concerns of wound dressing technology. The development of advanced biomaterials not most effective for scientific wound control but additionally for environmental sustainability. With the aid of leveraging biocompatible substances and modern technology, such as biodegradable polymers and eco-friendly nanoparticles, researchers goal to create wound care answers that no longer handiest sell green recovery however also limit environmental impact. Via analyzing the benefits, demanding situations, and future directions of hydrogel dressings, electrospun biopolymer nanofibers, and numerous polymeric substances, the study contributes to the discussion on sustainable wound care. It underscores the significance of developing wound care solutions that now not most effective reveal clinical efficacy but also consider their environmental effect. This holistic method resonates with the purpose of exploring the intersection of scientific efficacy and environmental sustainability in the context of biomedical substances for wound care.

This paper presents a detailed analysis of hybrid energy systems combining solar photovoltaic (PV) panels and hydropower technologies. Focusing on the increasing popularity of Archimedes screw generators for low head sites, we examine the efficiency and environmental benefits of such systems, particularly in reducing greenhouse gas emissions as part of global efforts like the Paris Agreement. We explore the integration of solar and hydropower systems in the context of Brazil’s renewable energy hybridization and discuss the challenges of their stochastic nature on power grid integration. The paper delves into the theoretical foundation, mathematical simulations, and optimization models that enable these hybrid systems to maintain energy and irrigation balance. The paper also investigates the use of photovoltaic-battery energy storage systems in building power supply and the potential of micro-grids featuring an array of renewable energy technologies. Ultimately, we present a novel approach to off-grid hybrid system deployment contributing to sustainable development goals.

The hybrid photovoltaic (PV)- wind based power generation systems are installing on many rooftops of individual houses, apartments, institutions, hospitals and small scale industries worldwide. Even though it is connected to single phase utility grid, a battery is used for backup power supply during power cuts. The diesel generators also can be integrated to this system for supplying continuous power long term. This configuration can establish a nanogrid under low power systems. Many loads are operated under this nanogrid system, hence a proper control technique is required to maintain power quality as well as to compensate reactive power. Compensating reactive power demanded in nanogrid through the inverter can reduce the reactive power demand on the main utility grid. Individual maximum power point tracker (MPPT) circuits are employed for both PV and wind to harvest maximum power. The system is synchronized with single phase utility grid through the control of the inverter. In order to maintain the good power quality, controller is designed for inverter to maintain the single phase voltages at its reference values. MATLAB Simulink platform is used to present the results for testing the performance of the proposed method.

The challenging situations of growing energy consumption, waste collection and destruction of the surroundings had been made greater apparent by means of the explosive rise of the global population and commercial interest. Modern techniques based on the 5R principle (Recycle, Reduce, Reuse, Recover, and Repaired) are critical to efficaciously addressing these problems. One promising way to turn non-recyclable waste into beneficial power assets is waste-to-power (WtE) the conversion method. This work presents a comprehensive evaluation of various WtE technologies, consisting of pyrolysis, gasoline production, anaerobic digestion, and combustion, highlighting their ability to reduce waste associated troubles. Furthermore, as supplementary techniques for sustainable waste control methods, it seems at the combination of progressed waste control (IWM), higher landfill mining, and sustainable substances control (SSM). The impact on the environment of waste-to-power changes are evaluated through a radical evaluation of current research and technology advancements, emphasizing decreases in landfill utilization, GHG emissions, and the promoting of renewable energy resources. The consequences highlight the essential role that WtE generation performs in accomplishing power efficiency improvements, cleaner production, and the development of the round financial structure. Ultimately, the article makes suggestions for future studies initiatives and coverage recommendations intended to optimize the economic and environmental gains from WtE deployments.

As the healthcare landscape embraces the revolutionary power of digitalization, improving inventory systems has become a top priority. Hospital asset tracking primarily focuses on monitoring various assets within a healthcare facility. These assets encompass human resources, medical equipment, vehicles, and other essential resources crucial for seamless hospital operations. Tracking assets in a hospital setting can range from monitoring individual medical devices to overseeing entire fleets of equipment and staff resources. The central objective is to maintain real-time records of asset status, and location to optimize productivity while minimizing costs. This project tracks the assets within the hospital using RFID sensors and outside the hospital using GPS. Radio frequency identification system (RFID) is an automatic technology and is used to identify objects, and record data through radio waves. Hospital asset management and tracking has become one of the main priorities in healthcare as it saves hospitals both money and time. Hospitals are under constant pressure to persistently track their medical equipment and supplies to make sure that they are properly utilized. This enhances financial performance and ensures the delivery of high-quality patient care. These are the advanced approaches to improve hospital asset management through real-time tracking and data analysis.

The research introduces a novel approach to animal and human detection using sonar technology in fields such as disaster management, and under water exploration. Unlike traditional visual methods, sonar systems emit soundwaves to analyze echoes, providing unique advantages in challenging environments. The proposed method involves collecting raw sonar data, followed by preprocessing techniques for noise reduction, signal normalization, and feature extraction. Sonar’s ability to penetrate various media, including water and dense fog, makes it valuable for detecting animals and humans in low-visibility conditions. Additionally, sonar operates effectively in both day and night settings, unaffected by lighting conditions. The proposed detection system will undergo comprehensive experiments using representative datasets and real-world scenarios. Performance metrics, such as detection accuracy, precision, recall, and computational efficiency, will be analyzed and compared with existing approaches. The study showcases the effectiveness and viability of employing sonar technology for animal and human detection tasks, highlighting its unique capabilities in challenging environments.
