“…However, there were some experimental data presented for various polymers such as acrylonitrile butadiene styrene (ABS), polycarbonate (PC), and others 37 in the form of CTE as a function of Young's modulus. This is the second set of data required for the present approach, as displayed in Figure 2.…”

“…When E m and E t are available, values of CTE in the stretching and transverse directions, MD and TD, can be evaluated with the aid of Figure 2. 37 The advantage of the proposed approach is that once an operating temperature is fixed, and a suitable draw ratio is selected, the related stress can be readily obtained using the formulas presented above. Consequently, values of birefringence, Young's modulus, and CTE can be evaluated without experimentation.…”

“…In addition, theoretical works applicable to PI films for the estimations of birefringence and Young's modulus for a given set of temperature and draw ratio inside the operating window are presented. CTE can be evaluated indirectly from a master curve constructed from the existing data of CTE as a function of Young's modulus for different materials 37 and different types of PI.…”

An operating window, which is bounded by two temperatures and draw ratios, defines the stable and defect-free stretching region of a polymer film. Physical properties including the coefficient of thermal expansion (CTE), birefringence, and Young's modulus of a recyclable polyimide (PIR) film were measured under stretching conditions. While values of birefringence and Young's modulus increased with increasing stretching stress in the machine direction, the CTE was found to decrease. A semiempirical model for the prediction of birefringence and Young's modulus under stretching conditions was developed, from which the CTE could be estimated from the Young's modulus data. Theoretically evaluated physical properties were found to be in qualitative agreement with the experimental data.

“…For example, the strategic control goal is the core and the key,the managing control goal is fundamental to the success of the whole objectives. If there is no management control target, the strategic control objectives are meaningless [3][4][5]. Low-carbon tourism enterprises in accordance with the macroeconomic environment and micro-environment is neededto achieve management and control objectives, and considerationof the low-carbon tourism business management and social responsibility is required to achieve the operational objectives and social responsibility objectives.…”

Abstract. On the internal controlof low-carbon tourism enterprise social responsibility, there have been but very few domestic-related academic research. This paper points out the problems of internal control of social responsibility of low carbon tourism enterprises;analyzes thecharacteristics of the internal control, its principles and procedures and finally it points out the methods of internal control of low -carbon tourism enterprises' social responsibility. On the basis of reviewing the existing literature, this article focuses on the development trend of low-carbon tourism enterprises, emphasizes the direction of internal control of tourism social responsibility, and is expectedto promote the academic research and development of internal control of low-carbon tourism enterprises.

Abstract. This article aims to assess the potential environmental impact of an electrical grinder during its life cycle. The Life Cycle Inventory Analysis was conducted based on the Simplified Life Cycle Assessment (SLCA) Drivers that calculated from the Valuation of Social Cost and Simplified Life Cycle Assessment Model (VSSM). The detailed results for LCI can be found under Appendix II. The Life Cycle Impact Assessment was performed based on Eco-indicator 99 method. The analysis results indicated that the major contributor to the environmental impact as it accounts for over 60% overall SLCA output. In which, 60% of the emission resulted from the logistic required for the maintenance activities. This was measured by conducting the hotspot analysis. After performing sensitivity analysis, it is evidenced that changing fuel type results in significant decrease environmental footprint. The environmental benefit can also be seen from the negative output values of the recycling activities. By conducting Life Cycle Assessment analysis, the potential environmental impact of the electrical grinder was investigated.
