Passive Augmentation Studies in a Double Pipe Heat Exchanger with Ellipsoidal Dimples
Abstract: In this work, the numerical studies of heat transfer augmentation of a counter-current double pipe heat exchanger with ellipsoidal dimples (inward-facing, raised dimples) on the inner tube was performed using SOLIDWORKS software. The effect of dimple depth, dimple pitch and number of dimples/angles between two dimples on heat transfer was investigated at a constant volumetric flow rate of 4 LPM for hot (water) and cold (water) fluids. The effect of …

Assess the Mental Wellbeing of Girl Students with Demographic and Social Factor
Abstract: Girl students’ performance totally depends on their mental and physical strength. So, to assess the student’s mental health is noteworthy. The Warwick Edinburgh Mental well-being scale (WEMWBS) is a reliable and validated tool to assess the mental wellbeing of the students in India. This study aims to assess the WEMWBS and compare scale with the demographic and social factors in India. The convenient sampling method was used to assess WEMWBS …

Microvita‑Inspired Informational Field Dynamics as a Nonlinear Signal‑Generation Mechanism in Matter–Life–Mind Systems
Abstract: Recognizing how matter, life, and consciousness relate to one another continues to be among the most essential challenges faced by modern science. Contemporary physical theories successfully describe the behavior of elementary particles and large-scale cosmological structures, yet they do not fully explain the emergence of informational complexity and organized patterns observed in biological and cognitive systems. This study proposes a theoretical framework in which Microvita are interpreted as subtle informational …

Smart Drug Delivery Using Nanorobots
Abstract: In recent years, the field of micro/nanorobot research has gained popularity. Because it can be used in targeted medication distribution, surgical procedures, disease detection, etc., it has enormous promise in medical therapy. Different from conventional medication delivery, which depends on blood flow to drug delivery to difficult-to-reach locations is made possible by the planned micro/nanorobots' ability to move independently. Micro/nanorobots were powered by either endogenous power (chemical reaction energy) or …

Effect of Notch on Low Cycle Fatigue of AA 2024-T351
Abstract: Notch effect on low cycle fatigue of AA 2024-T351 was investigated. Decreasing notch curvature leads to less cyclic hardening. Values of fatigue strength exponent (b) and fatigue ductility (c) for notch specimens were out of range of metallic materials. The SEM examination showed multi-crack origins with secondary cracks and a large final-fracture zone for unnotched specimens, while there was small final fracture zone close to the center of the specimen …
