Comparative Analysis of Polymer-Enhanced and Conventional Magnetorheological Fluids in E-Bicycle Semi-Active Suspension
Abstract: In light of the increased use of electric bicycles as a sustainable transport means, various mechanical challenges emerge which were absent in traditional bicycles, primarily concerning vibration isolation and riding comfort. Indeed, hub motors, batteries and the entire drivetrain system produce dynamic excitations which passive suspension cannot handle effectively. This paper presents a comparison of conventional magnetorheological (MR) fluid and the polymer-based MR nanocomposite fluid within the context of semi-active …

A Study of Composite Concrete Using Palm Oil Fuel Ash (POFA) as a Partial Replacement for Cement in Self Compacting Concrete
Abstract: Due to its flexibility at young ages and its capacity to be moulded into any necessary structural form and shape, concrete is the most commonly used construction material. For concrete to be workable and to have the necessary strength and durability, thorough compaction utilising vibration is typically necessary. Large numbers of voids are caused by inadequate concrete compaction affecting the structural strength and long-term toughness. Self-Compacting Concrete (SCC) offers a …

Mechanisms of Crystal Growth: From Spiral Steps to Surface Adhesion
Abstract: Crystal growth is a complex interplay between thermodynamic stability and kinetic processes, influenced heavily by the conditions under which crystallization occurs—particularly the degree of supersaturation. This abstract outline three principal regimes of solution-grown crystal growth: defect-driven, two-dimensional, and adhesive growth. At low supersaturation, growth is facilitated at surface defects, such as screw dislocations, where energy barriers to attachment are minimized. This results in the formation of spiraling steps that propagate …

Analyzing Thermal Expansion in Polymer Composites Through Heat Transfer Simulations
Abstract: Although lightweight and strong, polymer composites require careful handling in environments where temperatures shift. Their usefulness in fields like aviation, vehicle manufacturing, and electronic devices comes from customizable heat behavior alongside favorable mechanical traits. Yet variation in size due to heating or cooling remains a concern hard to dismiss. As conditions change, expansion occurs - sometimes enough to disrupt fit, alignment, or function within complex systems. This response to warmth …

Role of Application of SWCR Guidelines in Management of Right Trochanter Pressure Injury (PI)
Abstract: A pressure injury refers to the localized death of tissue resulting from sustained pressure on the skin and underlying tissues. This damage is often compounded by shear forces or direct trauma to the skin. While terms like “decubitus ulcer,” “bedsore,” and “pressure sore” are commonly used interchangeably, they fail to capture the complexity of the condition as accurately as the term “pressure injury” does. The term “decubitus” originates from Latin, …

Analysis of Die Corner Gap Formation for Strain Hardening Materials in ECAP Through an Upper Bound Sensitivity Approach: A Comparative Study
Abstract: In recent work, using a proposed central composite factorial analysis, the upper-bound theorem's theoretical concept for the equal channel angular pressing process are used. The upper-bound theorem-based theoretical solutions consider Tresca friction conditions and varied fillet radii at the die channel junction. When using AA5083's uniaxial mechanical properties, isotropic nonlinear work hardening is assumed. The ratio of the cumulative effective plastic strain to the time generated by the deformation zones, …

Use of Geopolymer Composites for Controlling Structural Cracks
Abstract: A building’s safety and stability can be compromised by ignoring the potential structural issues indicated by occurring cracks in buildings. Extensive damage may cause over the period from unidentified cracks.Good quality concrete never cracks in normal service conditions unless high horizontal force is applied. Through the cracks, carbon dioxide is released into the concrete and speeds up carbonation throughout the cracks, thus reducing the structure usage. The materials which are …

A Systematic Review on Peptic Ulcer Disease and its Pharmacological Treatment
Abstract: A chronic gastrointestinal condition known as Peptic Ulcer Disease (PUD) is typified by the formation of ulcers or mucosal erosions in the proximal duodenum and stomach. In the pathophysiology of PUD, the equilibrium between defensive processes like mucus and bicarbonate secretion, mucosal blood flow, and prostaglandin production, and aggressive factors such stomach acid secretion, pepsin activity, and Helicobacter pylori infection, is upset. Although stress and food have historically been blamed, …

The Effect of Dynamics and Mass Transfer Limitation on the Kinetic Growth Rate of Methane Gas Hydrates
Abstract: Hydrate management aims to prevent impediments to fluid flow in pipes caused by hydrate deposition. To achieve this goal effectively, a comprehensive understanding of the thermodynamics and kinetics of hydrate formation is essential for predicting their equilibrium conditions, quantifying the amount of deposition, and estimating the associated risk. Hydrate growth studies are a relatively new field, and independent laboratory experiments have shown that hydrate growth is controlled by heat transfer, …
