Gamma- and Electron Beam-Induced Crystalline modification in Poly (Lactic Acid): Effects of Radiation Dose and Dose Rate
Abstract: Poly(lactic acid) (PLA) is an important commercial biodegradable polyester whose properties are dictated by its molecular architecture and semicrystalline nature. The application of ionizing radiation particularly gamma rays and electron beams is extensive for sterilization and materials processing. The effect of ionizing radiation on the crystallinity of PLA is complex however, since irradiation causes concurrently chain scission, radical formation, oxidation, recombination and mobility driven structural reorganization. This work studies the …

Reliability-Aware Mathematical Model for Radiation-Hardened Satellite Communication Systems
Abstract: Satellite communication systems operate in radiation environments in which total ionizing dose (TID), displacement damage, and single-event effects (SEE) can progressively degrade electronic, optoelectronic, and communication components and can ultimately reduce link availability and mission reliability. This paper develops a Reliability-Aware Radiation-Hardened Satellite Communication Model (R-RHSCM) that mathematically couples the orbital radiation environment, accumulated radiation dose, component degradation, communication-link performance, single-event failure probability, redundancy, thermal effects, and adaptive mitigation. The …

Abstract: Ocular inserts are sterile preparations which are to be placed into cul-de-sac or conjuctival sac. The major aim of ocular insert is to maintain a therapeutic level at the site of action for prolonged period of time. The therapeutic efficacy of an ocular drug can be greatly improved by prolonging its contact with the corneal surface. Ocular insert gives several advantages like increased ocular residence time, drug release at a …

Toxicological Profiling and Safety Assessment of NASAT 2.0: A Conceptual Framework for Adaptive Nanoparticle Therapy in Rabies
Abstract: Rabies, caused by the highly neurotropic Rabies lyssavirus, remains one of the most enigmatic and universally lethal infectious diseases known to modern medicine. Once clinical symptoms manifest following successful neuroinvasion, the fatality rate approaches absolute certainty (approximately 99.9%), a staggering statistic that has remained largely unchallenged despite massive, concurrent advances in modern virology, critical care medicine, and cellular immunology. Current late-stage therapeutic protocols, most notably the widely debated Milwaukee Protocol, …

Mechanisms and Applications of Lyoluminescence
Abstract: When strongly energized halide or organic crystals are dissolved in а liquid solvent like water, light is emitted as an end result of а recombination process. This emission of light is known as Lyoluminesсenсe0. The emitted light intensity, called the Lyoluminescent intensity, depends on а class of factors like radiation doses, probability of radiative recombination, rate of dissolution inside the solvent, etc. The effect is enhanced when the materials have …
