Background & objectives: Polyethylene terephthalate (PET) containers have many applications in the food industry. Although there are numerous advantages for PET it also has some disadvantages, one of which is the migration of materials from the container into the material inside. In this study, the effect of two factors of storage time and temperature on the migration rate was evaluated and mod...
Oils extracted from plants have been used since ancient times and in many cultures .frying oils are used in many countries all around the world including Iran. Therefore it is of great importance to ensure the safety of these food products which are usually delivered in polyethylene terephthalate (PET) bottles. This study has investigated the effect of storage time and temperature on the migrat...

Because of the suitable characteristics such as having desirable burning rate, easily manufacture and high purity and yield, pay attention to Ferrocene compounds as commonly burning rate catalysts of composite propellants. Migration of this compound in during shelf time is their main disadvantage. This process can be caused reduction of propellant efficiency and creation of secondary hazards. T...

Methods & Materials This study is a secondary and descriptive-analytical analysis. The source used is the data of the general population and housing census and the analysis unit is the counties of th...
survival, proliferation, and migration of human meningioma stem-like cells in a nanopeptide scaffold
objective(s): in order to grow cells in a three-dimensional (3d) microenvironment, self-assembling peptides, such as puramatrix, have emerged with potential to mimic the extracellular matrix. the aim of the present study was to investigate the influence of the self-assembling peptide on the morphology, survival, proliferation rate, migration potential, and differentiation of human meningioma st...

Cementing is an essential part of every drilling operation. Protection of the wellbore from formation fluid invasion is one of the primary tasks of a cement job. Failure in this task results in catastrophic events, such as blow outs. Hence, in order to save the well and avoid risky and operationally difficult remedial cementing, slurry must be optimized to be resistant against gas migration phe...
