Use of NMR and Other Spectroscopy Techniques in Heterocyclic Oxadiazole Derivatives Studies: A Review
Abstract: It was possible to create a number of novel symmetrical 2,5-dialkyl-1,3,4-oxadiazoles with substituents including carboxymethylamino, isopropyloxycarbonylmethylamino, and bromine at the terminal positions of the alkyl groups. The multistep process that was devised used hydrazine hydrate, phosphorus oxychloride, and commercially available acid chlorides that varied in alkyl chain length and terminal substituent.Diisopropyliminodiacetate was an easy way to substitute the intermediate bromine-containing 2,5-dialkyl-1,3,4-oxadiazoles. This was followed by hydrolysis in an aqueous methanol …

Managing Blow-by in Modern Engines: A Comprehensive Review of Crankcase Ventilation Technologies
Abstract: Blow-by in internal combustion (IC) engines occurs when high-pressure combustion gases escape past the piston rings into the crankcase. These gases typically carry oil aerosols, unburned hydrocarbons, and fine particulate matter, which, if not effectively managed, can disrupt lubrication, accelerate component wear, and contribute to harmful emissions. Effective crankcase ventilation is therefore essential not only for ensuring engine durability but also for meeting increasingly stringent emission regulations. This paper examines …

Representation-Theoretic Symmetry Reduction and Fuzzy-Grey Optimization of Modular Vibration Systems
Abstract: This paper presents a representation-theoretic framework for symmetry-aware vibration control in modular structural systems. Exploiting cyclic symmetry, the mass, damping, and stiffness operators are block-diagonalised into irreducible representations, reducing the full structural dynamics to a collection of lower-dimensional modal subsystems. This decomposition provides both computational efficiency and a rigorous mathematical description of symmetry-preserving dynamic behaviour. To account for imperfections arising in practical implementations, near-symmetry defects in stiffness and damping are …
