Using Speckle Dynamics for Comparison of the Metabolic Activity of Different Cell Cultures

The dynamics of speckles in the image plane of a monolayer of cells cultivated on a glass substrate has been recorded. Cell cultures HEL-3, L-41, and Vero were selected as the objects of research. The digitized value of the radiation intensity I in one pixel and the parameter η characterizing the change in the intensity distribution on an 10 × 10 pixel area was recorded for 24 hours. The multiple determinacy coefficient of three cell cultures, which was obtained from the time dependences of η, was equal to 0.94.

A rain-on-snow mixed flood forecast model and its application

Based on summarizing the rule of rainstorm and snowmelt mixed flood, the structure of rain-on-snow runoff-generation is discussed; and critical temperature is used to determine the form of precipitation and snowmelt factor, taking into account rainfall volume of snowmelt. A rain-on-snow flood forecast model is developed by combining LL- I distributed hydrology model. The Kalangguer River, an internal river in Xinjiang Autonomous Region, is taken for example. It is indicated that the model has a higher precision of forecasting; its determinacy coefficient is greater than 0.80.
