Introduction: Interferon beta is one of the members of type I interferons. Creating R27T and V101F mutations is one of the important researches performed to improve function, decrease immunogenicity, increase expression and increase half-life of interferon beta. In this study, the effects of R27T and V101F mutations on interferon beta binding to interferon receptors were studied by molecular do...

The current method for composition measurement of an industrial distillation column includes an offline method, which is slow, tedious and could lead to inaccurate results. Among advantages of using online composition designed are to overcome the long time delay introduced by laboratory sampling and provide better estimation, which is suitable for online monitoring purposes. This paper pres...
