Abstract Large-size scintillators with high efficiency and ultrafast radiation fluorescence have shown more potential in the applications to ionizing detection of medical diagnosis, nuclear control high-energy physics. Currently, although traditional made tremendous progress scintillation efficiency, there are still challenges left lifetime. Faced that problem, we adopted 2-inch ZnO as substrat...

Inversion of sucrose by bakers' yeast follows the same course as inversion catalyzed by yeast invertase. Rate of inversion increases exponentially with temperature; the temperature characteristic in the Arrhenius equation is 10,700 below 13-17 degrees C., and 8,300 above that temperature. Temperature inactivation occurs above 40 degrees C. The effects of temperature upon rate of inversion were ...

Heat shock transcription factors (HSFs) are stress-responsive proteins that activate the expression of heat shock genes and are highly conserved from bakers' yeast to humans. Under basal conditions, the human HSF1 protein is maintained as an inactive monomer through intramolecular interactions between two coiled-coil domains and interactions with heat shock proteins; upon environmental, pharmac...
