This issue of the International Journal of Advance Research and Innovation presents a range of unique and varied studies.

Being rooted in physics concepts and centred around machinery and engineering, this issue brings us illuminating studies such as ‘Analysis of Ball Bearings under Dynamic Loading Using Non-Destructive Technique of Thermography,’ ‘Thermodynamic Irreversibilities Analysis of Industrial Ice Plant,’ ‘Performance Optimization of Four Stage Cascade Refrigeration Systems using Energy-Exergy Analysis in the R1234ze & R1234yf in High Temperature Circuit and Eco-friendly Refrigerants in Intermediate Circuits and Ethane in the Low Temperature Circuit for Food, Pharmaceutical, Chemical Industries,’ ‘Experimental Investigation of Friction and Wear Behaviour at the Interface of Aluminium and Mild Steel,’ ‘To Study Effect on Current Due to Channel Length Variation,’ ‘Effect of Heat Source on Mixed Convection of Non-Newtonian Fluids through Porous Medium along A Heated Vertical Flat Plate,’ ‘Mathematical Study of Reliability and MTTF of Industry under Common Cause Failure’ and ‘Mathematical Analysis of Reliability of M Out Of N Warm Stand by System with Repair Facilities.’

Research concerning technology has also been given representation in studies such as ‘Rectangular Patch Antenna for public safety WLAN and IMT band Applications,’ ‘Dual-Frequency Band Circular Microstrip Antenna for Radar Application,’ ‘Design and Simulation of Dual Band Rectangular Patch Antenna for WiMAX & IMT Band Application’ and ‘To Design and Implementation of Framework for Firewall Policy with Minimum Rule Set.’

Contributing to the contemporary and essential discourse on the environment are studies such as ‘Methods for Improving Thermodynamic Performance of Vapour Compression Refrigeration Systems Using R134a Eco-friendly Refrigerant in Primary Circuit and Three Nano Particles Mixed with R718 used in Secondary Evaporator Circuit for Reducing Global Warming and Ozone Depletion; and ‘Optimization of Production and Performance of Biodiesel through Optimization Techniques: A Review.’

Other niches are explored through studies such as ‘Use of Hydrocarbons in Low Temperature Circuit in Terms of First Law and Second Law Efficiency of Four Stage Cascade Refrigeration of Semen Preservation,’ ‘Total Quality Management in Technical Educational System’ and ‘Liberalization of Textiles and Clothing Trade and Evolving Global and Indian Trade Scenario.’

We hope that the diverse range of subjects covered in this issue act as ‘food for thought’ for our readers and prove to be intellectually stimulating for them. The support of the readers and the contributions of all the authors to the global discourse on the subjects is greatly appreciated.
