Evaluating Fiber Volume Fraction and Defects in Fiber Reinforced Polymer Composites for T Joint applications
Abstract: Fiber-reinforced polymer (FRP) composites have been integral to industries such as aviation, aerospace, shipbuilding, and automotive due to their strength, durability, lightweight, and corrosion resistance. This study examines the production and microstructural analysis of polymer composites using FRP and manual lamination methods. While manual lamination is quick and economical, it relies on operator skill, resulting in low mechanical properties. Microstructure analysis via 3D optical and scanning electron microscopes revealed that …

Electrical Properties of Nanocrystalline CuxO Thin Films Prepared by r. f. Sputtering Method
Abstract: Normal 0 Nanocrystalline CuxO (0 < x < 1) thin films have been synthesized using r. f. sputtering method at different r. f. power in an atmosphere of O2 and Ar. The effect of varying r. f. power, oxygen partial pressure and film thickness during deposition on the crystal size and electrical properties of CuxO thin films have been studied. The films were characterized by X-ray diffraction (XRD), transmission electron …

Role of Asbab-e-Sitta Zarooriya in Ziyabetus Shakri (Diabetes Mellitus) an insight of Unani Medicine: A Review
Abstract: Diabetes mellitus is a metabolic disorder characterized by hyperglycemia resulting from defects in insulin secretion, action or both. This can arise in many different ways but it is most commonly due to autoimmune type 1 diabetes or to adult-onset type 2 diabetes. Lack of insulin affects the metabolism of carbohydrate, protein and fat, and can cause a significant disturbance of water and electrolyte homeostasis. Globally an estimated 422 million adults …

An Empirical Analysis of Cost, Time, and Quality Relationships Using Correlation and Regression Techniques
Abstract: Cost, time, and quality have been recognized as the three key dimensions that determine construction project performance and are commonly represented through the "Project Management Triangle." However, despite their theoretical linkage, there is limited empirical evidence to quantify the nature of their relationships, particularly within developing construction markets. This paper seeks to contribute to addressing this shortfall by investigating the specific influence of cost and schedule variations upon quality outcomes …

Flexural Response and Numerical simulation of Unidirectional Areca–Pineapple Leaf Fiber Hybrid Epoxy Composites
Abstract: The increasing demand for lightweight and environmentally sustainable materials has accelerated the development of natural fiber-reinforced polymer composites for engineering applications. In the present study, unidirectional areca and pineapple leaf fiber (PALF) reinforced hybrid epoxy composites were fabricated using a simple hand lay-up process. Before fabrication, the fibers were chemically treated to improve fiber–matrix adhesion and enhance the mechanical performance of the laminates. Four different stacking sequences (A8, A7P1, A6P2, …
