Mathematical and experimental modeling of reverse osmosis (RO) process
Zeinab Hadadian,Sina Zahmatkesh,Mostafa Ansari,Ali Haghighi,Eskandar Moghimipour 한국화학공학회 2021 Korean Journal of Chemical Engineering Vol.38 No.2
This paper provides a mathematical simulation model for the reverse osmosis (RO) process with series elements. A mathematical simulation model was developed based on the mass, material and energy balances considering the concentration polarization. The simulation model is open-source and easy to couple with other computational tools like optimization algorithms and SCADA1 applications. An RO laboratory pilot was also set up in the Hydraulic Lab of Shahid Chamran University of Ahvaz to validate the simulation results. Comparing the results of the simulation model with the experiments and ROSA commercial software, the proposed simulation model functions well and is reliable. The comparisons indicate that the simulation results are over 96% close to ROSA and over 80% close to experimental results.

The Incidence and Mortality of Liver Cancer and its Relationship with Development in Asia
Mohammadian, Maryam,Soroush, Ali,Mohammadian-Hafshejani, Abdollah,Towhidi, Farhad,Hadadian, Fatemeh,Salehiniya, Hamid Asian Pacific Journal of Cancer Prevention 2016 Asian Pacific journal of cancer prevention Vol.17 No.4
Background: Liver cancer (LC) is the sixth world most common cancer and the second leading cause of cancer death. Due to the importance and necessity of awareness about the incidence and mortality of diseases to perform prevention programs, this study focused on data for LC and its relationship with the human development index (HDI) and its components in Asia in 2012. Materials and Methods: This ecological study was based on GLOBOCAN data for Asian countries. We assessed correlations between standardized incidence rates (SIR) and standardized mortality rates (SMR) of LC with HDI and its components using of SPSS18. Results: A total of 582,420 incident cases and 557,097 deaths were recorded in Asian countries in 2012. The five with the highest SIR were Mongolia, Lao PDR, Vietnam, Republic of Korea and Thailand and those with the highest SMR were Mongolia, Lao PDR, Vietnam, Cambodia and Thailand. A negative relation was observed between HDI and LC for SIR of 0.049 (P=0.748) and for SMR of 0.07 (P=0.645), with life expectancy at birth a positive relation for SIR of 0.061 (P=0.687) and a negative relation for SMR of 0.079 (P=0.603), with the average years of education a negative relation fo SIR of 0.476 (p=0.952) and for SMR of 0.032 (P=0.832), and with the country income level per person a negative relation for SMI of 0.11 (p=0.465) and for SMR of 0.113 (P=0.455). Conclusions: The incidence of LC is more in less developed and developing countries but statistically significant correlations were not found between standardized incidence and mortality rates of LC, and HDI and its dimensions.
