Objective: People who have higher social health can more successfully deal with the challenges and ups and downs of playing key social roles and participate more in collective activities and prevent social deviations and anomalies. In this regard, foresight and the development of a forward-looking strategy model by the MEDIA can play an important role in promoting the social health of their audience (individuals).Method: This research has been done qualitatively and quantitatively. In the qualitative phase, content analysis and Q methods were used, and in the quantitative phase, factor analysis was used to analyze the Q method data.Results: The content analysis of the MEDIA in this study showed that the most MEDIA production in the field of social deviations with 576 cases and the lowest MEDIA production in the field of violence with 237 cases. The field of social quality with 485 and the field of social issues with 312 cases are in the second and third ranks. A small questionnaire was made and based on it, the desired model was designed using PLS software. Conclusion: This model showed that the function of MEDIA is effective in promoting social health of society and can have the greatest impact on improving quality of life, reducing violence, reducing social deviations and social issues.

Habitat suitability prediction for the animals is one of the ways to achieve the conservation goals for biodiversity. In the present study, habitat suitability of Lacerta MEDIA has been evaluated. Based on the maximum entropy result, northwest and western Iran has been predicted as the most suitable for the species presence. Also there are several records of the species presence in Alborz, Markazi, East Azarbaijan and Esfahan provinces that currently situated outside of the suitable predicted region. Precipitation of the coldest quarter with contribution more than 40% was distinguished as the most contributed environmental variable for species presence. Unsuitability prediction of the species presence in central plateau and East Azarbaijan province directly has been influenced by the recent decreasing of winter precipitation. Also, disturbance the habitats of the species along valleys and rivers is the main factors to the decreasing population size of the species. Finally, evaluation the effective factors for species distribution and finding new suitable areas for species presence can help to prevent the species extinction risk in the wild.

In order to determine the role of the US withdrawal from Joint Comprehensive Plan of Action (JCPA) in 2018 in the evolution and change of the poverty framing, this study analyzes how poverty is framed in two categories of specialized (including leadership, Dolat, Mizan, Icana) and general websites (including Fars, Moj and Young Journalists Club) during 2017, 2018 and 2019. For this, it uses Framing as a theory, and the technique of Pan and Kosicki’s Frame analysis as a research method. Findings are categorized in four groups as syntactical, script, thematic, and rhetorical. The review indicates that 42,302 news and reports are distributed in these websites in the research period that 275 were identified as samples and recorded and analyzed in Maxquda software. The results show that, except for the Young Journalists Club, the way poverty is framed has changed on all cases since the imposition of sanctions, and sanctions highlighted as one of the main causes of poverty in the framing of poverty. In regard of agenda setting, the coverage of poverty news and reports is less than 10%; the poverty news coverage has been declining over the three years under study. The websites of Leadership and Moj have the largest coverage, and Young Journalists Club has the least amount (less than 1%) of coverage. Due to his type of agenda setting, the problem of poverty is marginalized in public opinion. The framing of poverty with emphasis on the US withdrawal from JCPA as the cause of poverty represent poverty as a temporary issue, silences the voice of the poor, and depicts the emergence of a new social form in Iranian society.

This study aimed to investigate the effect of different culture mediums based on the Walne medium on the growth rate, chemical composition, and fatty acid (FA) profile in I. galbana and N. oculata. This experiment was done in a factorial design with two culture MEDIA (Walne and modified Walne MEDIA) and two microalgae species, including I. galbana and N. oculata. The results showed that the modified culture medium increased total and daily fresh and dried biomass production of I. galbana and N. oculata. Modified culture MEDIA increased crude fat (CF) and crude protein (CP) content and total and daily lipid production in both the studied species. However, in both the studied culture mediums, N. oculata had higher growth and production performance compared to I. galbana. Modified growth MEDIA also affects the FA profiles of the studied microalgae species. Total saturated and unsaturated FA content was not influenced by the growth medium but modified MEDIA increased poly unsaturated FA (PUFA) at the expense of mono unsaturated FA (MUFA). Omega- 3 FA content (linolenic acid, Eicosapentaenoic acid (EPA), Docosahexaenoic acid (DHA)) was increased as a result of the medium modification in both species. However, linoleic acid content was affected differently in I. galbana and N. oculata. The linoleic acid concentration was reduced in modified medium grown N. oculata but increased in I. galbana. Palmitic acid and stearic acid contents were also decreased in both of the studied species in the modified medium. This study develops microalgal cultivation using a modified Walne medium for higher CP, CF, EPA, DHA contents, the ratio of omega3: omega6 FA, and biomass production in N. oculata and I. galbana microalgae.Microalgae species can produce oil and protein in non-cultivable lands, reducing the need for defrosting and can have an important role in reducing carbon foot-print of animal production. One of the most valuable products of microalgae is their oil, which ranges from 20 to 50% of the dry weight of microalgae (Brennan and Owende 2010; Leonga et al. 2018). The I. galbana is often grown on farms to produce oils that contain large amounts of PUFA rich in omega-3 long chain FA, such as EPA and DHA (Gouveia et al. 2008). Species of the genus N. oculata are also known to be rich in EPA (Kagan et al. 2014; Borges et al. 2016). Factors such as nutrient quantity and quality, light, pH, turbulence, salinity, and temperature are the most important parameters on which, the growth of microalgae depends (Lavens and Sorgeloos 1996; Converti et al. 2009; Emmanuel and Nelson 2016). Vitamins regulate biochemical reactions in microalgae (Hakalin et al. 2014) and the growth rate of some microalgae species is highly dependent on some the vitamins such as cobalamin, biotin and thiamine (Tandon et al. 2017). However, the effect of vitamins on the growth, diversity, and productivity of microalgae has been poorly studied (Arif et al. 2019). The effects of different Nitrogen and phosphorus concentration as the main limiting nutrients on growth performance and biomass production of I. galbana and N. oculata had been evaluated previously (Andersen 2005; Zarrinmehr et al. 2020). However, there was not any report about effects of modifying the availability of culture medium sources of nitrogen and phosphorus. In the composition of the Walne medium, No3-, Po4-, and Cl- are considered as anions, and Na+, Mn+, Co+, Zn+, and Cu+ are considered as cations. Cations chelating anions and making them less available to microalgae. So, we hypothesize that changing the concentration of cations in the culture MEDIA, without increasing the concentration of N and P sources, will change the availability of anionic compounds for microalgae and consequently affects microalgal production and composition. Therefore, the effects of lower levels of cations including ZnCl2, CoCl2. 6H2O, (NH4)6Mn7O24, and CuSo4. 5H2O and higher levels of B1 and B12 vitamin in Walne medium on the growth rate, biomass production performance, chemical composition, and fatty acid profile of I. galbana and N. oculata, were investigated in this study. This study aimed to investigate the effect of different culture mediums based on the Walne medium on the growth rate, chemical composition, and fatty acid (FA) profile in I. galbana and N. oculata. This experiment was done in a factorial design with two culture MEDIA (Walne and modified Walne MEDIA) and two microalgae species, including I. galbana and N. oculata. The results showed that the modified culture medium increased total and daily fresh and dried biomass production of I. galbana and N. oculata. Modified culture MEDIA increased crude fat (CF) and crude protein (CP) content and total and daily lipid production in both the studied species. However, in both the studied culture mediums, N. oculata had higher growth and production performance compared to I. galbana. Modified growth MEDIA also affects the FA profiles of the studied microalgae species. Total saturated and unsaturated FA content was not influenced by the growth medium but modified MEDIA increased poly unsaturated FA (PUFA) at the expense of mono unsaturated FA (MUFA). Omega- 3 FA content (linolenic acid, Eicosapentaenoic acid (EPA), Docosahexaenoic acid (DHA)) was increased as a result of the medium modification in both species. However, linoleic acid content was affected differently in I. galbana and N. oculata. The linoleic acid concentration was reduced in modified medium grown N. oculata but increased in I. galbana. Palmitic acid and stearic acid contents were also decreased in both of the studied species in the modified medium. This study develops microalgal cultivation using a modified Walne medium for higher CP, CF, EPA, DHA contents, the ratio of omega3: omega6 FA, and biomass production in N. oculata and I. galbana microalgae.
