Thermal Modeling and Optimization of Irreversible Cogeneration Power Plant
Abstract: This paper aims at studying the cogeneration system coupled with outer heat reservoir of finite heat capacity and comprises of both external as well as internal irreversibility. External irreversibility is due to the finite-rate heat transfer between the working fluid and heat reservoirs while internal irreversibility is due to heat dissipation of working fluid. Both types of irreversibility are involved in the study on introducing an internal irreversible parameter which …

Non-Equilibrium Entropy Pathways in Complex Fluids: A New Framework for Thermodynamic Irreversibility
Abstract: When a system is driven, sheared, stretched, heated, or pressurized under varying thermodynamic gradients and kept away from equilibrium, ultra-microscopic rearrangements begin to occur, indicating continuous energy dissipation. Along these energy pathways, the microstructures of complex fluids undergo multiple stages of reforming and rearrangement. In complex fluids composed of identical compounds (chemically identical species), these interactions play a supportive role and reduce the overall entropy of the system. However, when …

Entropy-Based Damage Accumulation in Tribological Systems: A Comprehensive Review
Abstract: This paper reviews classical wear models and entropy-based degradation approaches used for predicting failure in tribological systems. Various wear models, thermodynamic frameworks, and applications of the Degradation Entropy Generation (DEG) theorem are discussed. Friction, which is the primary source of heat generation in tribological contacts, is responsible for material degradation through a variety of irreversible processes. While classical wear approaches have been widely used for wear prediction and life estimation, …

Intersections between Architecture and Culture and Heritage Management
Abstract: Architecture and culture are deeply interconnected, with each influencing and reflecting the other over time. Buildings are more than physical structures; they represent the beliefs, traditions, values, and lifestyles of the communities that create them. As societies evolve, architecture becomes a living record of their social, political, economic, and technological development. At the same time, cultural heritage management plays a crucial role in protecting and preserving these architectural assets, ensuring …

Investigating Analogue Gravity Phenomena through Electronic Black Holes: A Study
Abstract: The universe, in its grand cosmic ballet, is replete with mysteries, and among the most profound are the enigmatic black holes. These celestial behemoths, born from the collapse of massive stars, warp spacetime to such an extent that nothing, not even light, can escape their gravitational embrace. Their behavior, governed by Einstein's theory of General Relativity, pushes the boundaries of our understanding, presenting phenomena like Hawking radiation – a quantum …

Enhancing Glaucoma Detection with Convolutional Neural Networks: A Data-Driven Approach
Abstract: One of the main causes of irreversible blindness is glaucoma, which is characterized by certain alterations in the optic nerve that over time can impair vision. Manual evaluations, while invaluable, are challenged by inconsistencies, subjectivity, and the extensive time required. The study employed a dataset comprising retinal images annotated by experts. By using Convolutional Neural Networks (CNNs) to study and recognize important patterns in eye images, it was possible to …

Evaluating the impact of a structured educational program on cpr knowledge among nursing students in selected colleges at Mangalore
Abstract: The heart functions as a muscular pump responsible for propelling blood throughout the body's tissues, ensuring a continuous supply of oxygen and nutrients while removing metabolic waste products. Oxygen plays a crucial role in the body's energy production, and its absence can lead to cell death in vital organs such as the brain and other body parts. The heart's rhythmic action and respiratory efforts are essential for transporting oxygen to …

Maculopathy Detection and Recommendation using Machine Learning
Abstract: Maculopathies, a diverse group of eye diseases affecting the central portion of the retina, the macula, are a leading cause of vision loss globally. Early detection and accurate diagnosis are critical for timely intervention and preventing irreversible vision loss. However, traditional methods such as manually detecting the disease are time-consuming, tiring, and often lack sensitivity and specificity, hindering optimal patient care. Here we delve into the applications of machine learning …

Analysis and optimization of exergy losses in a heavy water distillation column
Abstract: Heavy water (D2O) of isotopic purity 99.9% and more is used as the moderator and the coolant in pressurized heavy water nuclear reactors (PHWRs). This purity is maintained by vacuum distillation. In the column there are various sources of irreversibility and thermodynamic inefficiency. This work presents an analysis of these losses in a typical heavy water distillation column and their dependence on various design and operating parameters of the column. …

Deforestation: Causes and Consequences of the Global Crisis
Abstract: Climate change is unavoidable due to the dynamic character of global ecosystems. The reasons of these environmental changes are both man-made and natural. Human activities have always had an impact on the environment. As economic activity and population expansion have risen to the point that they can no longer be disregarded or seen in isolation, the consequences of mankind just on environment could no longer be ignored or examined in …

THERMODYNAMICS OF HEAVY METALS (Hg2+, Cd2+, Fe2+AND Ni2+) ADSORPTION USING BOILER FLY ASH
Abstract: The effect of temperature on the adsorption of heavy metals, Hg2+, Cd2+, Fe2+ and Ni2+ using unactivated boiler fly ash (an agricultural waste) was investigated. The results showed that Hg2+ and Cd2+ ions were mostly affected by increase in temperature because their sorption rate decreased at high temperature. At the temperature of 273 K and 383 K, the amount of Hg2+ adsorbed (mg/g) by the unactivated boiler fly ash was …

Laws of Thermodynamics Challenge Greenhouse-Gas and CLIMATE- change Hypotheses
Abstract: The greenhouse-gas hypothesis (GGH), i.e., CO2 is the cause of global warming by ~1K from ~1950-2023, is popularly believed to be established scientific truth. It is generally assumed that heat emissions from global fuel combustion are, by comparison, negligible. An application of the Hess-Gibbs 1st law of thermodynamics, however, shows that the enthalpy (H) output from yearly fossil fuel consumption is seven times greater than the H- increase of hypothetical …

Home Care Management of Arterio-venous Fistula Among Chronic Renal Failure Patients Undergoing for Hemodialysis- A Quasi-experimental Research Study
Abstract: Introduction: Chronic Renal Failure refers to a gradual and irreversible decline in renal function, leading to the body's inability to sustain metabolic, fluid, and electrolyte balance. This condition results in uremia, necessitating the reliance on hemodialysis to maintain internal equilibrium and prevent uremia. In the initial phases of renal impairment, symptoms may be alleviated through hemodialysis, monitoring fluid intake, dietary regulation, and medication use. However, as renal function deteriorates, these …
