Motivated by the long-term goal of understanding vectorial biological processes such as proton transport (PT) in biomolecular ion pumps, a number of developments were made to establish combined quantum mechanical/molecular mechanical (QM/MM) methods suitable for studying chemical reactions involving significant charge separation in the condensed phase. These developments were summarized and dis...
introduction: cholestasis is impairment of normal bile excretion into the duodenum and classified as mechanical and non mechanical cholestasis. mechanical cholestasis presents with increase in bile duct diameter or obstruction in bile duct in an ercp. cholestasis leads to different complications. one of these complications is mucosal peptic erosion leading to gastrointestinal bleeding, perforat...
objective(s): the aim of this study was to synthesis new dental nanocomposites reinforced with fabricated glass nanoparticles and compare two methods for fabrication and investigate the effect of this filler on mechanical properties. materials and methods: the glass nanoparticles were produced by wet milling process. the particle size and shape was achieved using psa and sem. glass nanoparticle...
