        The main objective of this study is to investigate how cash flow and systematic risk can affect corporate diversification. When it comes to investment decisions and financial considerations in companies, diversification plays a crucial role. Studies indicated that corporate diversification influences employees’ productivity, cash retention, investment costs and overall company value. Diversification helps companies reduce risks when they encounter economic or market conditions. In other words, it assists companies in anticipating and preventing market changes and disruptions, thereby minimizing the impact of systematic risks. This research follows a descriptive and ex-post facto approach, categorized as cause and effect. The analysis of variables has been performed using multiple linear regression. Data from 118 companies between 2018 to 2022 were collected for research purposes. In order to analyze the data and test the hypotheses, Excel and EVIEWS software have been employed. The findings of this study indicate a relationship between systematic risk and corporate diversification. However, cash flow of companies and corporate diversification exhibited no significant correlation. Additionally, the results suggest that cash flow acts as a moderating variable that significantly influences the relationship between corporate diversification and systematic risk. Manuscript profile

        The Middle East region accounts for the largest quota of the world's energy reserves, which is the reason for the interdependence between the world's largest industrial countries and the governments of this region. Given the known oil reserves of the Arab countries in the Persian Gulf region, the effect of energy consumption with a sample of five Arab countries as members of OPEC and oil producers of the Persian Gulf region on greenhouse gas emissions during 40 years (1980-2020) was investigated in this research. The energy production and consumption and greenhouse gas emissions of the target countries were studied to identify their contribution to energy production and consumption in the world. It was determined that these countries account for a significant share of climate change and global greenhouse gas emissions. The results show that approximately 34% of the global oil reserves and 22% of carbon dioxide (CO2) production belong to the five Arab countries in the Persian Gulf region. The largest and the lowest shares in CO2 production belong to Saudi Arabia and Kuwait among the five countries of the Persian Gulf region. Manuscript profile

        Conceptualization and Design of a Digital Content Marketing Model Using Structural Equation Approach Abstract Content marketing refers to the importance of valuable and relevant content in the marketing process. On the other hand, the growth and development of media and digital tools and the growing trend of their use have doubled the importance of paying attention to digital marketing tools and caused the emergence of a new topic called digital content marketing. The research presented the fit of the digital content marketing model to the economic, social, political, and cultural conditions of Iran. This research is practical in terms of purpose, and the researcher has used a quantitative method. The sampling method was a simple random method, according to Cochran's formula. The sample included 384 users of Digikala's Instagram page, which initially defined hypotheses and collected the necessary information through a 5-point Likert questionnaire. To measure the results of the research, the method of measuring structural validity and the method of modeling structural equations were used to test the hypotheses of the research, and with the help of SmartPLS.3 software, factor analysis of the dimensions of the research was also performed. After conducting the necessary analysis, it was found that there is a significant relationship between the variables discovered in the digital content marketing model, and the existing assumptions were confirmed. This result shows that the obtained model can be used in digital content marketing. Manuscript profile

        Damping-off is actually a general term for several diseases with similar symptoms that attack new plant seedlings and are caused by several pathogenic soil fungi, including Pythium, Phytophthora, Fusarium, and Rhizoctonia. In Iran, the damping-off disease of summer crop More
        Damping-off is actually a general term for several diseases with similar symptoms that attack new plant seedlings and are caused by several pathogenic soil fungi, including Pythium, Phytophthora, Fusarium, and Rhizoctonia. In Iran, the damping-off disease of summer crops is known by the local names of dry green, scorching, and water-affected, and is a major disease of cucumbers, melons, watermelons, and pumpkins. This disease has been prevalent in all cultivation areas of these plants, including Khuzestan, Isfahan, Fars, Kerman, Jiroft, Tehran, Varamin, Saveh, Kashan, Lorestan, Qazvin, Hamadan, Khorasan, Bandar Abbas, Azerbaijan, and Mazandaran. Agricultural, chemical, and biological control methods are applied in the management of cucumber damping off. In general, a review of the research showed that the use of chemical and biological pesticides is a very suitable solution to control plant rot, because if it is not controlled in time, it can destroy the entire crop and cause irreparable damage to the greenhouse or farm owner.

        This study was an attempt to investigate the effect of corporate diversification on cash retention. Diversification is a risk management method that combines different types of investments. Diversification is a model for developing a company by offering diverse products and services. This study is experimental and fundamental in terms of its purpose and correlational in terms of its nature. The study data were extracted from the observed values of eighty-nine stock companies during ten years from 2002 to 2021. The collected information is company-year and the purpose of the study is to test the effect of independent variables on the dependent variable to investigate the effect of corporate diversification on cash retention in companies listed on the Tehran Stock Exchange. According to the collected information and using the combined model of regression analysis, three models were fitted and three hypotheses were tested. The results obtained from the investigated models support the inverse effect of corporate diversification indices including commercial diversification index, commercial diversification dummy variable, and geographical diversification dummy variable on cash retention. A dummy variable is referred to as an indicator of technological changes at a certain point in time. However, the results did not support the effect of the geographic diversification index on cash retention. Manuscript profile

        With the recent advances in the application of biotechnology in various sciences, the preparation of liquid bio-formulations and microcapsule suspension/powder from the important antagonistic fungal agent Talaromyces flavus has been investigated in recent years. In the first year of this research, a type of liquid bioformulation, a type of microcapsule suspension, and a type of microcapsule powder were prepared for use in tomato greenhouses. During one year, commercial greenhouses were investigated in tomato greenhouses in two regions of Yazd and Isfahan with a history of Fusarium wilt disease. The treatments in each study of the commercial greenhouse were 1-3) each of the liquid formulations, microcapsule suspension, and microcapsule powder by soil application, 4-6) each of the liquid formulations, microcapsule suspension, and microcapsule powder with the tomato seedling root dip, 7) Talaromin fungicide by soil application, and 8) a control (without any formulation and fungicide application). The results indicated that all three formulations in both application methods (soil application or seedling root dip and seed impregnation for tomatoes and cucumbers, respectively) significantly increased the yield of tomatoes compared to the control. Altogether, microcapsule powder with seed impregnation and liquid formulation with soil application were the most effective treatments with approximately 50% and 60% increases in yield compared to the control, respectively, for the management of tomato Fusarium wilt disease. According to the obtained results, the production method of these formulations is considered technical knowledge, and it is possible to carry out their commercialization steps. Manuscript profile

        Research on the impact of digital currency technology on exchange costs is progressing, with studies highlighting various aspects. Blockchain technology is seen as a mechanism that can reduce transaction costs by enforcing contract execution through encryption, bringing transactions closer to the conditions of a perfectly competitive market. Additionally, digital currency issuance can influence currency circulation speed and money multiplier, affecting financial system risk and supervision. While the influence of Bitcoin on exchange rates is noted to be negligible, the importance of embracing decentralization and digital money for cost reduction and transparency in enterprises is emphasized. Furthermore, the introduction of central bank-issued digital currencies (CBDCs) is being explored, with different design options impacting transaction costs for various stakeholders.
