Cryopreservation of pancreatic islets enables their long-term storage and subsequent transplantation; however, post-cryopreservation, viability, functions are reduced to a significant extent. Islet is composed five cells (? cell, ? ? ? PP cell), blood vessels that carry the nutrition. Freezing technology organization has not developed good method. This paper studied using fructan which been fou...

The Weibull distribution has been widely used in survival and engineering reliability analysis. In life testing experiments is fairly common practice to terminate the experiment before all the items have failed, that means the data are censored. Thus, the main objective of this paper is to estimate the reliability function of the Weibull distribution with uncensored and censored data by using B...
