  Background and objectives: Meso-scale eddies are not only dynamically important, but also climatologically, environmentally, as well as in terms of air-sea interaction are of special importance. Due to the existence of oil and gas fields, the Persian Gulf is exposed to oil pollution, analyzing the role of factors such as meso-scale eddies in the spread of pollution in the Persian Gulf is very important.Methods: In this study, sea level data related to the analyzed Aviso reference data series (2010-2014) were used and meso-scale eddies were identified and tracked using a method based on sea level, and the relevant maps were drawn. This method is more effective than other common methods of tracking eddies.Findings: By studying the location of formation of eddies, eddy distribution coefficient was also calculated and the results indicated that eddies created in spring have a larger scale and higher speed, while eddies created in winter have a smaller scale and lower speed.Discussion and Conclusion: The eddies located in the north and south of the Persian Gulf have moved to the west and east of the Persian Gulf, respectively, which is consistent with the results of other studies. The range of the most eddy activity in the entrance parts of the Persian Gulf is from the Strait of Hormuz and inclined to the coast of Iran as well as northwest of the Persian Gulf. The maximum number of eddies is observed in summer and winter and the least number of eddies is observed in spring and autumn. Manuscript profile

  In recent years, the development of nanoparticles in the field of drug release has received much attention. This research aims to develop new methods for the physical modification of Fe3O4 superparamagnetic nanoparticles with polymers through physical retention. In this study, after synthesizing the biodegradable polycaprolactone-polyethylene glycol magnetic copolymer, the anticancer drugs doxorubicin and Chrysin in these polymers were encapsulated by dual emulsion (w / o / w). The effect of temperature and pH on drug release was investigated. After performing kinetic studies, the diffusion coefficient of drug release was also studied. The drug distribution was considered uniform and the system was assumed to be in Cartesian coordinates. The results showed that the diffusion coefficient of drug release followed Fick's law. At first, due to the high concentration difference of drugs in the early times, the diffusion coefficient was higher, but then with time and with decreasing the concentration difference, the diffusion coefficient decreased and remained constant.
