Abstract: The enhancement of heat transfer in air conditioning (AC) evaporators is essential for improving system efficiency, reducing energy consumption, and meeting modern environmental standards. This review focuses on the role of material optimization in improving the heat transfer performance of AC evaporators. Various materials such as copper, aluminum, and composite structures are evaluated based on their thermal conductivity, corrosion resistance, weight, and cost-effectiveness. Advanced approaches, including nano-coatings, porous structures, and hybrid materials, are also discussed for their potential to enhance heat exchange rates. Furthermore, the use of computational techniques like Finite Element Analysis (FEA), Computational Fluid Dynamics (CFD), and optimization algorithms such as Genetic Algorithms (GA) plays a significant role in simulating and selecting optimal materials and designs. This review concludes that material optimization, combined with innovative surface treatments and smart design techniques, holds significant promise for the next generation of high-efficiency AC systems.

Abstract: Pavements are complex structures involving many variables, such as materials, construction methods, loads, environment, maintenance, and economics. Thus, various technical and economic factors must be well understood to design, build pavements, and to maintain better pavements. Moreover, the problems relating to pavement maintenance are still complex due to the dynamic nature of road pavements where elements of the pavement are constantly changing, being added or removed. These elements deteriorate with time and therefore to be maintained in good condition requires substantial expenditure

Abstract: In this work, we report the growth of different types of two-dimensional(2D) carbon nanostructures and their change in the morphology, growth and size on Si substrate with deposition time. The 2D carbon nanostructure were grown in the presence of Argon plasma with Methane as a carbon source without any special pre-treatment of the substrate using Radio Frequency Plasma Enhanced Chemical Vapor Deposition (RF-PECVD). Field Emission Scanning Electron Microscopy (FE-SEM) and Atomic Force Microscopy (AFM) were proven the grown carbon nanostructures were hexagonal Islands, rod shaped and white patches like structures. We identified the changes in the diameters of the grown nanostructures from 35-130 nm with deposition times 30 to 120 minutes. The surface roughness of the samples was reported by the 3D analysis of AFM. The presence of D and G peaks was identified by Raman Spectroscopy. Raman spectroscopy showed that the ratio of I(D)/I(G) increases with increasing deposition time.

Abstract: The increasing global demand for protein, together with environmental degradation, animal welfare concerns, and food safety risks associated with conventional poultry farming, has motivated research into lab‑grown (cultured) poultry. This review (or article) explores the state of the art in cultured‐meat technology applied to poultry: from cell sourcing and culture media, to scaffolding, bioreactor design, tissue vascularization, and challenges in mimicking texture and flavor. It discusses the potential advantages of lab‑grown poultry—reduced greenhouse gas emissions, lower land and water use, elimination of slaughter, and improved safety control—and weighs these against the technical, regulatory, economic, and consumer‑acceptance obstacles. The article concludes by projecting a pathway toward commercialization, outlining necessary innovations and policy frameworks, and evaluating the prospects for lab‑grown poultry becoming a mainstream component of the human diet.

Abstract: In our fast-moving digital age, the demand for automation and intelligent systems is on the rise. More and more people are turning to digital assistants to help them juggle tasks, enhance workflows, and minimize manual effort. However, many of the voice assistants available today struggle with multitasking, remembering context, and executing tasks effectively. This gap creates a mismatch between user expectations and the capabilities of current virtual assistants. Enter M.A.T.T.I.S (Multi-Functional Assistant for Task, Technology, and Intelligent Support). This innovative solution aims to bridge that gap by integrating cutting-edge automation, multi-language processing, and AI-driven conversational memory. Built on Python frameworks, M.A.T.T.I.S leverages advanced speech recognition and natural language processing to deliver highly accurate responses. Unlike traditional virtual assistants, M.A.T.T.I.S is crafted to manage multiple tasks simultaneously, minimizing delays and enhancing productivity. It also boasts smart automation features, allowing users to control system functions, access real-time data, and streamline their digital activities effortlessly. This paper takes a deep dive into M.A.T.T.I.S ’s system architecture, workflow, and implementation strategies. It also compares M.A.T.T.I.S [Multi-functional Assistant for Task, Technology and Intelligent Support] with leading commercial voice assistants, showcasing its superior efficiency in task execution and user-friendly design. Additionally, the study presents real-life scenarios where M.A.T.T.I.S significantly improves task management in both professional and personal settings. A series of tests were conducted to assess the assistant’s accuracy, efficiency, and performance in real-time situations. The results reveal an impressive 95% accuracy rate in speech recognition, an average response time of under a second, and the capability to seamlessly handle over 50 tasks simultaneously.

Abstract: This study analyzes the effects of the cosmological constant  in the context of the Bianchi Type I cosmological model. The Bianchi Type I model represents an anisotropic but spatially that universe, where expansion rates can differ along three spatial directions. The cosmological, plays a significant role in the universe expansion. This work aims to understand how influences the expansion, energy density, and anisotropy of the universe. Einstein's field equations with variable cosmological constant if considered in the presence of a perfect fluid for a Bianchi type I universe by assuming that the cosmological term is proportional to the square of the Hubble parameter. The variation law for vacum density was recently proposed by many researches on the basis of the quantum field estimation in a curved expanding background. The cosmological term tends asymptotically to a genuine cosmological constant and the model tends to a de- Sitter universe. More obtained some new results by using a slightly different method from that of other researchers obtained the result that the present universe is accelerating with a large fraction of cosmological density in the form of a cosmological term.

Abstract: – It is increasingly important for high-rise buildings in urban environments to consider blast threats arising from explosions. When blast loads produce high-amplitude and short-duration pressure pulses, they primarily pose a threat to the facade systems, which are at risk from high-rise blowouts. It could also cause harmful reactions over the world and the gradual breakdown of weak systems. The state-of-the-art in semi-active structural control techniques (particularly magnetorheological (MR) dampers) and passive protective measures (glazing, cladding, sandwich panels, anchorage/retention systems) is summarised in this review. Hybrid design approaches that integrate adaptive damping and material resilience are also examined. In order to identify critical research gaps (scaling of semi-active devices, controller latency for impulsive loads, long-term durability, and standards integration), we survey empirical blast test programs, standards and guidance documents, numerical modelling approaches, controller algorithms, and device technologies. We then suggest a prioritised research agenda that includes system-level testing, predictive control research, and demonstration projects.

Abstract: This project introduces a smart environmental monitoring and alert system built using IoT technology. The system uses a NodeMCU (ESP8266) microcontroller connected to three important sensors: the DHT11 for measuring temperature and humidity, a Flame Sensor for detecting fire, and an MQ6 Gas Sensor for identifying dangerous gases like LPG and propane.Data from these sensors is collected in real time and sent to the Blynk IoT platform, where it can be viewed on a mobile app. The system also includes a Telegram Bot API that sends immediate alerts to the user’s Telegram account when dangerous situations occur, such as high temperature, gas leaks, or fire detection. This ensures that users are informed quickly, even if they are not physically present near the sensors. The system is affordable, easy to expand, and suitable for home safety, industrial use, and remote monitoring.Using IoT platforms and instant messaging services, this system provides a practical method for smart alerts and real-time detection of environmental dangers
