Application of Three-dimensional Differential Transform Method to Dynamic Vibration Analysis of Rectangular Plate Resting on Elastic Foundation
Abstract: Research on vibration analysis of non-homogenous and varying thickness plate has gained a tremendous increment in recent year due to its vast application in many fields of engineering. This study investigate the dynamic behavior of rectangular plate with varying thickness resting on two-parameter foundation under simply supported free edge condition. The governing differential equation is analyzed using three-dimensional differential transform method. The accuracies of the established solutions are verified by …

Analysis Of Non-Uniform Damped Rayleigh Beam Resting on Pasternak Foundation Subjected to Distributed Load With Variable Axial Force
Abstract: In this paper, damped non-uniform Rayleigh beam resting on Pasternak foundation and subjected to distributed load with variable axial force has been investigated. The solution techniques to the governing equation describing the dynamical system are based on Galerkin’s method, Laplace integral transformation in conjunction with convolution theorem. Galerkin’s method is explored to reduce the fourth order non-homogeneous partial differential equation to a second order ordinary differential equation. The resulting equation …

Potato Starch-Based Polyethylene Composite: Fabrication and Evaluation
Abstract: This study's objective was to create and evaluate a biodegradable polymer composite consisting of potato starch (PS) and low-density polyethylene (LDPE). The effects of changing the PS content (10– 40 wt%) on the mechanical (elongation at break and tensile modulus), thermal (heat conductivity), and biodegradability characteristics of the polymer composite were examined. Next, it was examined how the cross-linking agent influenced the polymer composite's mechanical and thermal properties. The melt …

Eco-Friendly Chemical Processes: The Role of Green Chemistry in Modern Industries
Abstract: Green chemistry focuses on the development of chemical products and processes that minimize or eliminate hazardous substances, promoting sustainability throughout the chemical life cycle. Unlike environmental chemistry, which studies pollutants, green chemistry proactively designs safer alternatives to prevent environmental damage. This field spans multiple disciplines, including organic, inorganic, analytical, and physical chemistry, with applications across pharmaceuticals, manufacturing, and materials science. The principles of green chemistry, first formulated by Paul Anastas …

Analysis of Geological Structure for the Application of Geotechnical Engineering to Optimize Thermal Extraction in Geothermal Wells
Abstract: The characterization of the geological terrain for geothermal applications from the heat transfer point of view has been made. Horizontal, vertical and inclined geological layers have been analyzed. Uniform and homogeneous terrain are better candidates for low or high enthalpy geothermal applications while heterogeneous soil have a poorer performance from the thermal transfer point of view. The characterization process of soil structure and properties allows to take the appropriate decision …

Study of Mechanical Properties of Aluminum Nanocomposites using Auto Ignition Technique
Abstract: Al2O3 - high ZrO2 nanocomposite was synthesized by auto-ignition technique using metal nitrate and citric acid with a ratio of citrate: nitrate equal to 1:1.5. The precursor zirconium oxynitrite was derived from precipitation of zirconium oxycloride followed by dissolution of gel in nitric acid. The thermal decomposition behaviour of the gel was studied in order to study the decomposition behaviour and to determine the crystallization temperature. The effect of calcination …
