The Thermal Stability of Polymaleimide

The Stability and Thermal Performance of a Small Solar pond

A small salt gradient solar pond with an average surface area of 1.8 m2 and depth of 0.8m has been tested. The depths of storage, gradient and surface zones are 0.3, 0.27 and 0.07m, respectively. The temperature of the storage zone for the summer days reaches its maximum of 65˚ C after about 8 days. Daily variation of the storage zone temperature was about 8˚C which is due to small volume of th...

Improvement of Thermal Stability of BCG Vaccine

Background: Thermal stability (TS) is a part of the BCG vaccine characterization by which the consistency of process in BCG vaccine production could be confirmed. To enhance the TS of the vaccine, some prevalent stabilizers in different concentrations were added to the final formulation of BCG bulk prior to Freeze-drying process. We found a formulation more effective than the current stabilizer...

Investigation of the Relationship between the Residual Moisture and Thermal Stability of Lyophilized MMR Vaccine

Background and Aims: The safe, potent and effective live vaccines against Measles, Mumps and Rubella as important childhood diseases have been available for several decades. Several factors can affect the thermal stability of lyophilized vaccine. Methods: In this study, the effect of residual moisture on thermal stability of 61 batches of MMR vaccine was investigated using an accelerated ...
