Introduction: Academic faculty members need to emphasize ethical principles in order to improve higher education, with the understanding of this importance, the current research was conducted with the aim of designing the ethical model of academic faculty members in Iran's higher education. Material & Methods: This research is a type of qualitative study that uses foundational data theory. The participants, including experts and faculty members of the country's public universities, who were responsible for the promotion of academic members, were selected as key informants through a targeted sampling method of 45 people. Data were collected through semi-structured interviews. The reliability and validity of the data were obtained from the two methods of reviewing the participants and recoding by experts. Data were analyzed by open, central and selective coding. Results: The results showed that the moral model of faculty members in Iran's higher education is explained in 10 main categories and 27 subcategories. Major and core categories in the form of 6 dimensions of causal conditions including (individual factors, organizational factors), core (cultural-educational, educational ethics, research ethics, scientific-executive), background conditions (higher education policies, moral activism), intervening conditions (environmental factors), strategies (micro level-university, macro level-higher education) and consequences (individual and organizational) were elevated to a higher abstract level and finally the research paradigm model was presented. Conclusion: The regulations for the promotion of academic staff members in Iran require a detailed revision of the content with an ethical and qualitative approach in order to make the indicators of the promotion regulations efficient and effective.

The LOCAL press does not have the power to compete against the national press for various reasons, including the inability to provide the content required by the audience. The purpose of this study is to design a content quality management model in LOCAL Iranian newspapers to improve their content. This applied research was conducted with a qualitative-exploratory approach. The research community has included professors, experts, and activists in the field of LOCAL newspapers, among whom the number of 12 people continued to reach theoretical saturation through semi-structured in-depth interviews. The analysis was done through the foundation data method through Strauss and Corbin coding in three open, central, and selective levels in the Maxqda 2020 software. Then the concepts were presented in the form of a paradigmatic model (causal conditions, central phenomenon, strategies, background conditions, intervention, and consequences) and its validity and reliability were also confirmed based on the three-tier method. The results showed that the content of the LOCAL press can be effective in attracting the audience. In this way, the LOCAL newspapers of Iran need to innovate in the way of writing, control, monitoring, and correct targeting, paying attention to the current issues of the society, etc. increase society's thoughts.

In this work, the SLD model is used to investigate the adsorption of pure gases and binary and TERNARY mixtures of them on solids. The volumetric properties of the fluid phase are described by PR and EDS equations of state. Three different procedures are used to estimate the parameters of the model. In the first and second procedures, the model is considered to have 2 and 1 adjustable parameters respectively. However, in the third procedure, none of the parameters are adjusted. In all the three cases, only the data of the pure compounds are used. The results show that although the adjustment of the parameters improves the results for pure compounds, it does not necessarily improve the prediction of the model for the mixture of gases, and even in some cases, less reliable results are observed. As a result, good predictions are observed without fitting the parameters of the model. The average absolute percentage of deviation for the calculation of excess adsorption for pure gases with PR EOS is 6.6%, 10.0%, and 11.6% for procedures 1, 2, and 3 respectively. The corresponding values for ESD EOS are 8.1, 10.4, and 15.9. For binary gas mixtures, the errors are 2.7%, 3.9%, and 4.2% for procedures 1, 2, and 3 respectively in case of using PR EOS; ESD EOS results in errors of 4.7%, 3.5%, and 4.8% for procedures 1, 2, and 3 respectively. A TERNARY gas mixture composed of methane, ethane, and ethylene is also examined; the average absolute percentages of deviations are 5, 4, and 15.6 in case of PR EOS and 6.9, 8.9, and 17.4 with ESD EOS for procedures 1, 2, and 3 respectively. The comparison of the equations of state used show that PR equations of state generally produce better results.
