Background and Objectives: The Covid-19 pandemic caused serious challenges to various industries of wooden products in various aspects such as access to raw material, supply chain, production and sales volume of product and even customer preferences. Therefore, this study aims to investigate the mediating role of government support in relation to revising some adopted policies such as investment strategies, creating resilience in industries and improving financial knowledge of managers of these industries in order to increase production of various wooden furniture products in the post-corona era was done.Methodology: In terms of its nature, this research is fundamental-applied and in terms of the type of research, it is a part of mixed research including quantitative and qualitative variables.The study population consisted of 180 managers of home and office furniture manufacturing companies based in Tehran and Alborz provinces, from which 120 were selected through the Cochran formula. Field-library methods are used to collect preliminary information as needed, the main tool for collecting information for this research is a questionnaire approved by academic experts. The used questionnaire includes 22 questions related to research variables, including resilience, government support as a moderating variable, investment strategies, financial knowledge and production growth. Also, the scale used is a 5-point Likert scale. In this research, Cronbach's alpha coefficient, composite reliability and extracted average variance were used to determine the reliability and convergent validity of the questionnaire. In order to analyze the internal structure of the questionnaire and discover the constituent factors of each structure or variable, the confirmatory factor analysis tool was used. Also, to check and analyze the data, descriptive and inferential statistics were used using SPSS software, and to check the relationships between variables, structural equation method based on the use of Smart-Pls software was used.Results: The results of correlation between the variables show that at a significance level of 1%, the highest correlation is between financial knowledge variables with investment strategies, and the lowest correlation is between government support variables with production growth. Also, the reliability check of the questionnaire shows that there is reliability and convergent validity in the questions. The results of examining the measurement model using confirmatory factor analysis show that the items of the model are correctly defined and it is not recommended to remove any of them, because the values of the factor loadings are higher than the minimum acceptable value, i.e. 0.3. This study showed that there is a positive and significant relationship between investment strategies, resilience and financial knowledge as independent variables and positive growth as a dependent variable. Research findings show that the government support component is also related to production growth. It has a positive and significant relationship. In relation to the role of government support as a mediating variable in the relationship between investment strategies, resilience and financial knowledge on production growth of wooden furniture industry, the results show an effective relationship. In all these research hypotheses, the significance level of the p-value test is less than 5% and the T value is outside the range (1.96, -1.96), so it is significant with a 95% confidence factor.Conclusion: The results of this research revealed that in the post-corona era, wooden furniture industry may face new developments and changes. These changes can include changes in the needs and tastes of customers, the process of marketing and selling products, the use of environmentally friendly products, changes in the structure of companies and the necessity of creating industrial holdings, the necessity of using new technologies in production of various products in furniture industry and decoration, paying more attention to firm's internal structures to increase the level of resilience, using managers with extensive financial knowledge to deal with fluctuations of firm's financial assets. Also, in the post-corona era, government support for wooden furniture industries can play an important role in impact of investment strategies, resilience and financial knowledge on production growth of these industries.

In order to achieve the higher competitive advantage, identifying and prioritizing the various factors of sustainable supply chain management and its relationship with the performance of the companies producing home and office furniture, have been selected as the main purpose of this study. The statistical population in both the qualitative and quanitative parts consisted of experts, and specialists in the field of sustainable supply chain management and the company performance, including managers and operational engineers of furniture manufacturing companies in Tehran province. In the qualitative part, the interview method and content analysis were used to identify effective factors and in the quantitative part, a reseracher – made questionnaire based on Likert- scale was used to collect data and Pearson correlation and Friedman tests were used to understand the causal relationships between research variables and prioritize them. The validity and reliability of research tools in both parts were tested and confirmed using different methods. The results showed that supply chain management practices have a direct and positive effect on the home and office wooden furniture firms. Also in the sustainable supply chain management, the dimensions of delay time, product cost and design and adaptation to the environment were given first to third priority. Also in terms of performance, the dimensions of rapid response and the proposed changes of customers in the responsible volume, investment returns and customers' preference to buy from top names were given first to third priority.

The first step in feasibility study of any national mega projects in energy sector is the investigation on the production potential and evaluate the market demand for the product. The success rate of a biofuel project after forecasting supply and demand depends on choosing the appropriate place to produce. In this respect, factors such as the selection of appropriate production site, environmental, technical, economic and social are among major issues. In this study, autoregressive integrated moving average (ARIMA) model was used for the prediction of bioethanol demand in five sceneries; E5, E10, E15, E20 and E30. The time period up to 1412 is foreseen. The data on agricultural wastes and the present and future potentials for the bioethanol production in different provinces is analyzed. The results indicate that, the average daily consumption of gasoline will increase to 136,922 million liters per day as we reach 1412.The study also shows that there exists the potential for the production of 18.16 million liters of bioethanol which can fulfill the requirement of E5 and E10 by 1412. If we want to implement the E20 and E30 scenario in the country, it is necessary to increase the production of 7 selected products in this research, in the provinces of Khuzestan, Fars, Khorasan Razavi, Golestan, Isfahan, Mazandaran, Tehran, Qazvin and Alborz and Gilan by 62.2 million tons per year by 1412, And consider the effective factor in the success of the project, namely the support of the government and legislators for national mega projects.

Wet strength is one of the most important properties of tissue papers and presently the polyamideamine-epichlorohydrin (PAE) resin is widely applied to develop and conserve wet strength in paper products. In this study, the combined effect of PAE, retention aid (RTN) and carboxymethyl cellulose (CMC) on softness and wet and dry strength properties of tissue paper were investigated. The results showed that combined application of CMC, RTN and PAE significantly improved wet strength and softness of papers, as compared to single application of PAE. Application of 0.2 % RTN with 1% PAE or 0.4% CMC with 1% PAE enhanced wet tensile strength by 10% and 68%, respectively. The combined application of 0.4% CMC, 0.2 % RTA and 1% PAE improved wet tensile strength by 124%, compared to sheets treated with only the 1%PAE. The positive effect of combined application of CMC, RTA and PAE depends on the application ratio of the chemicals.
