Cellular Responses to Tartrazine and Sulfanilic Acid Exposure in BEAS‐2B Cells: Viability, Apoptosis, and DNA Damage

Journal of Applied Toxicology, EarlyView.
ABSTRACT Tartrazine is a synthetic azo dye widely used in food, pharmaceutical, and cosmetic products, resulting in extensive human exposure, while its toxicity and that of its primary metabolite, sulfanilic acid, remain controversial. Considering the reported association of tartrazine with hypersensitivity and allergic‐like reactions, human bronchial ...

Comet Gas and Dust Dynamics Modeling

, 2010
This software models the gas and dust dynamics of comet coma (the head region of a comet) in order to support the Microwave Instrument for Rosetta Orbiter (MIRO) project. MIRO will study the evolution of the comet 67P/Churyumov-Gerasimenko's coma system.

Comparing the dynamics of Jupiter-family Comets and comet-like fireballs

Astronomy & Astrophysics
Context. Jupiter-family comets (JFCs), which originate from the Kuiper belt and scattered disk, exhibit low-inclination and chaotic trajectories due to close encounters with Jupiter. Despite their typically short incursions into the inner solar system, a notable number of them are on Earth-crossing orbits, with fireball networks detecting many objects ...

Rheological Characterization and Multi‐Regime Viscosity Modeling of Diluted Polyethylene Mixtures

Polymer Engineering &Science, EarlyView.
This study maps the flow behavior of low‐density polyethylene in a recycling solvent from dilute solutions to entangled melts. By integrating time–concentration and time–temperature superposition, and coupling three complementary rheometry methods, a unified semiempirical model accurately predicts steady‐shear viscosity over nine decades of viscosity ...
