Raman Spectroscopy for The Determination of Relative Crystallinity of Carbon Fibers
Abstract: Analogous to X-ray diffraction technique, the light scattering technique discovered by Sir CV Raman has great potential in quantifying the crystallinity of new materials, like the highly crystalline pitch based carbon fibers (NX90 and NX100). For comparison the Raman spectra of polyacrylonitrile based carbon fibers (T700SC) were also recorded. From the Raman spectral analysis, it was found that the pitch based carbon fibers exhibit far far higher degree of crystallinity …

Parameters of “Safety” in the Food Additive Industry: A Review of Risks and Benefits
Abstract: “Safety is in the eye of the beholder.” What is deemed “safe” by one observer may seem dangerous or risky to others. To approach this apparent quandary and assure ongoing scientific input, most food additives should be tested on laboratory animals and subsequently monitored if approved for human or animal consumption (i.e., parallel to the pathway for the approval of drugs). The term “safety” in the study of the toxicology …

An Efficient Synthesis of Some Novel Benzo Coumarin Derivatives Under Solvent Conditions from 2-acetyl-benzo[f]chromen-3-one
Abstract: The synthesis of the target compounds began with the preparation of 2-[3-dimethylamino[acryloyl-3H-benzo[f]chromen-3-one. This intermediate was obtained through the reaction of 2-acetylbenzo[f]coumarin-3-one with N,N-dimethylformamide dimethyl acetal [DMFDMA[ under reflux conditions in xylene. The enaminone thus formed was subsequently reacted with 6-aminothiouracil in acetic acid, leading to the formation of 2-thioxo-2,3-dihydro-1H-pyrido[2,3-d]pyrimidin-4-one. This compound served as a pivotal intermediate for the synthesis of a series of pyridotriazolopyrimidinones. These derivatives were synthesized by reacting …

Study of Proximity Points and Fixed Points
Abstract: This paper explores the concepts of proximity points and fixed points, which are fundamental in mathematical analysis and nonlinear functional analysis. Fixed-point theorems play a crucial role in optimization, game theory, differential equations, and dynamic systems. Proximity points, an extension of fixed points, provide a more generalized approach, allowing near-coincidence rather than exact identity. The study discusses classical fixed-point theorems, such as Banach’s contraction principle, Brouwer’s fixed-point theorem, and Schauder’s …
