    The first-order biodegradation rate coefficients for RDX at 15, 10, and 5°C were , , and per day, respectively. The calculated activation energy for RDX was kJ ∕ mol. Columns with acetate as the sole electron donor achieved 22–46% mineralization of initial radiocarbon to CO 2 14, as compared to less than 5% in columns. The boundary lubrication and dry friction of plain bearings at different work temperature are unable to be avoided under the start and stop condition. The poor lubrication is one reason of bearing broken. In order to improve the tribological properties and select the best treatment for different bearings used at different temperature, the studies of different treatment technologies Author: Jun Cao, Liang Qin, Aibing Yu, Haibo Huang, Guoping Li, Zhongwei Yin, Huiyu Zhou. laboratory” should be placed in the “Remarks” portion of the log.

Introduction: The Laboratory for Low Temperature Physics is and organized collection of people who are interested in the exploration of phenomena found at low temperatures, particularly those found below the liquefaction temperature of liquid helium, K.

Therefore, for the same heat flow rate q, geometry and operating conditions, the heat transfer required area will result less in a counter-current configuration. Furthermore, considering the temperature profiles, in counter-current flow, the outlet temperature of a fluid can hypothetically reach the inlet temperature of the other fluid.

Also, this is again a test that provides data at only one “shear rate” (i.e. speed of hammer at impact). Polymer liquids have a viscosity that is exponentially dependent on temperature as well as shear rate dependent at a given temperature.
