Shiqaq-e-Maqad (Fissure in Ano) As Per Unani System of Medicine
Abstract: Anal fissure is one of the most common anorectal condition encountered in clinical practice. It is a longitudinal split in the anoderm, with surrounding oedema and inflammatory induration which causes painful defecation, bleeding with streaks of blood on the surface of stool or on toilet paper and itching per rectum. As per Modern aspect, the aetiology of anal fissure is not known. They generally arise with local trauma caused by …

Particle Swarm Optimization based PID controller for Extrusion Process
Abstract: The process called extrusion was used for making objects of fixed cross-sectional profile by pushing or pulling the material through the die of the preferred cross-section. The extrusion process was a nonlinear process in which the quality of the product relies on various parameters such as temperature, extrusion speed, etc.; hence there should be a controller working in an optimized manner required to maintain these parameters properly suitable for the …

Luminescent Phenomena and Materials: Fundamentals, Developments, and Multidisciplinary Applications
Abstract: Luminescence, defined as the emission of light without significant heat generation, represents a fundamental phenomenon bridging physics, chemistry, materials science, and biotechnology. Over the centuries, the understanding of luminescence has evolved from simple observational curiosity to a sophisticated quantum-mechanical framework describing electronic transitions in atoms, molecules, and solids. This review provides a comprehensive overview of the historical development, fundamental mechanisms, classifications, and material systems associated with luminescence. It places particular …

Self-Healing Graphene–Polymer Nanocomposite Encapsulation Layers for Ultra-Stable Perovskite Photovoltaic Modules under Extreme Environmental Conditions
Abstract: The recent trend is that perovskite photovoltaic modules are vulnerable to moisture, oxygen, thermal cycle, UV, and mechanical stress, which seriously affect the working stability of the modules under harsh environmental conditions, thereby hindering the rapid commercialization. In this study, a new self-healing graphene–polymer nanocomposite encapsulant layer is proposed to improve the durability and reliability of perovskite solar modules in extreme climates. The encapsulation system combines functionalized graphene nanosheets into …

Evaluation of Polymer-Ceramic Scaffolds for Dental Bone Regeneration
Abstract: Looking at the aspects of periodontal disease, traumatic injury, congenital defects, and the preparation of implant sites, the deficiency of dental bone, and its reconstruction, which has been simplified by many by oral and maxillofacial surgery, has proven to be a very hard and tedious task. There are many solutions which are clinically accepted, as the use of auto, allo, and xenografts, very common practices in surgery, but they come …

Effects of Halloysite Nano particle Reinforcement of Epoxy Composite Using a Diglycidyl ether of bisphenol-A Prepared by Ultrasonication Casting
Abstract: This study explores a simple and operative approach for developing stronger epoxy-based composite materials by incorporating halloysite nanotubes (HNTs). The composites were made-up through hydraulic compression casting, combining ultrasonic mixing with applied pressure to produce consolidated composite sheets. HNTs were added to the epoxy resin at concentrations ranging from 1 to 5 wt.% at approximately 60°C, and the subsequent composites were examined to understand their internal structure, nanotube dispersion, and …

Enhanced Room-Temperature Gas Sensing Performance of 2% Mn-Doped Sri Lankan Natural Graphite Thin-Film Sensors for Ammonia, Acetone, and Ethanol vapors Detection
Abstract: The development of room-temperature gas sensors with high sensitivity, fast response, and low-cost remains a critical challenge for environmental monitoring and safety applications. In this work, we report the fabrication and characterization of a 2% Mn-doped Sri Lankan natural graphite thin-film sensor for the detection of ammonia (NH3), ethanol (C2H5OH), and acetone (C3H6O) vapors under ambient conditions. The sensor was prepared using the doctor-blade coating method on Indium Tin Oxide …

Mechanical Characterization of Bio-Based Polymer Composites Manufactured by Additive Manufacturing
Abstract: The use of bio-based polymer composites in additive manufacturing is becoming more and more attractive, but their mechanical properties are very sensitive to the loading of reinforcement, the orientation of the raster and defects of the printing process. In this study, the mechanical properties of PLA–bagasse composites produced by material extrusion were studied, focusing on the influence of the reinforcement fraction and the deposition structure. The composites were tested with …

Detection and Assessment of Structural Weaknesses in Existing Offshore Structures
Abstract: The structural integrity and serviceability of existing structures may deteriorate over time due to aging, environmental exposure, material degradation, overloading, inadequate maintenance, and repeated operational stresses. Early identification of structural deficiencies is essential for preventing progressive damage and ensuring safe and reliable performance throughout the service life of a structure. This study presents a systematic structural condition assessment of an existing structure using visual inspection and non-destructive testing (NDT) techniques. …
