abstract  background: despite the long-standing association of macrophage migration inhibitory  factor (mif) with delayed-type hypersensitivity response, the potential role  of mif in chronic allograft nephropathy is unknown. the association between upregulation of mif expression, macrophage and t cell infiltration and the severity of  chronic allograft nephropathy suggests that mif may be an i...

   In chiral and non-chiral electrophoretic resolution of basic drugs, adsorption of analytes to negatively charged capillary wall could lead to poor repeatability of migration time and peak area. In addition, chiral resolutions of basic drugs are commonly performed in low pH buffers. Therefore, longer analysis time due to suppression of electroosmotic flow (EOF) is another dilemma. In this wor...

The Image reconstruction is an important problem in optical tomography. The process of the image processing requires the study of photon migration in biological tissue. There are several approaches to study and simulate propagation of photons in biological tissues. These approaches are categorized into stochastic and analytical groups. The Monte Carlo method as a stochastic method is widely use...

Recent attention on global environmental changes has stimulated the development of large scale global information systems. Satellite images play a very important role for understanding these global changes. However, the data size is very large and current commercial hierarchical le management systems are not e cient enough to handle such huge data les. Migration of a whole le from tape to disk ...

The ability to migrate a virtual machine (VM) from one physical host to another is important in a number of cases such as power management, on-line maintenance, and load-balancing. The amount of memory used in VMs have been steadily increasing up to several gigabytes. Consequently, the time to migrate machines, the total migration time, has been increasing. The aim of this thesis is to reduce t...

Background and Objectives: Making stacking gels for polyacrylamide gels in the laboratory by conventional methods is laborious and time consuming. Considering the role of temperature in polyacrylamide gels with respect to electrical resistance and viscosity, we assumed that decreasing the temperature would cause an increase in electrical resistance and viscosity.  Ultimately, a downward tempera...
