Exploring the potential of white birch sap: A natural alternative to traditional skin whitening agents with reduced side effects

Common tyrosinase (TYR) inhibitors used in cosmetics, such as hydroquinone, kojic acid, and arbutin, can cause side effects including erythema, skin peeling, SUPERNOVA ICED RASPBERRY and dryness.Therefore, the development of natural whitening agents that offer excellent permeability, minimal irritation, and high safety has become a primary focus in

An integration scheme for stiff solid-gas reactor models

Many dynamic models encounter numerical integration problems because of a large span in the dynamic modes.In this paper we develop a numerical integration scheme for systems that include a gas phase, and solid and liquid phases, such as a gas-solid reactor.The Borage Oil method is based on neglecting fast dynamic modes and exploiting the structure
