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.
