patients and methods this retrospective cohort study included 405 renal transplant patients from kerman university of medical sciences hospital, kerman, iran from 2004 to 2010. kaplan-meier method was used to estimate survival rates of patients, and time-dependent cox regression was used to examine the effect of allograft failure on patient survival. results during 4.06 years (median) of follow...

  In this paper the numerical analysis of flow and time dependent heat transfer of micro-tube conveying nanofluid in laminar flow is investigated. In this study, convection heat transfer of nanofluid and base fluid and transient analysis for time-varying heat flux for time step of 0.0001 second are elucidated. It is observed that the pumping power of nanofluid flowing and the maximum temperatur...
