Study on the influence of the cotton storage process on the quality indicators of fiber and yarn

This article defines fiber quality indicators that differ in laboratory conditions from the upper, middle and lower layers of Bukhara-6 breeding varieties of cotton, in the modern system HVI 1000 SA. Based on the results of the study, histograms of changes in the quality of cotton fiber in the layers of the harem are presented. As an alternative, the quality indicators of yarn obtained in the laboratory spinning device “Sherli” of small size from fiber were determined. As can be seen from the analysis of the test results, it was found that the comparative elongation strength of cotton obtained from the lower layer of the stack, the upper average length, elongation at break, the light output coefficient, decreased compared to other layers of the stack, on the contrary, the index of hip fibers, increased, decreased compared to other layers of the stack. In addition, according to the results of the tests obtained, the fiber viscosity index was obtained – the correlation between the properties of fibers and the properties of yarn, the thread viscosity index was estimated by the CSP (COUNT STRENGTH PRODUKT) coefficient, which was determined by the formula for carded yarn obtained in the laboratory spinning device “Sherli” from fiber stored in the refrigerator. The obtained results showed that the relationship between fiber properties and yarn properties due to the fact that the maturity index of a thread is at the top of the stack compared to the middle and lower part of the stack.

Design of Principal-agent Incentive Mechanism between Government and NPO

Based on principal-agent theory, this paper establishes an incentive contract mechanism between government and NPO under asymmetric information, and analyzes the impact of absolute risk aversion and output level on the expected utility of government, NPO and society. Research shows that risk aversion is negatively correlated with the expected utility of government, NPO and society. The output coefficient is positively correlated with the expected utility of government, NPO and society. Reducing absolute risk aversion, increasing output coefficient and increasing government incentives can effectively motivate NPO to actively participate in social rescue activities.

Analysis of Educational Quality Based on Quality, ServQual and Retention of Students

This study analyzed the influence of ServQual (service quality) on satisfaction and student retention. The sample used was 175 STIESIA Surabaya students using non probability sampling called, accidental sampling. Data analysis used Structural Equation Modeling (SEM) with AMOS 21 software. Based on the discussion of the hypotheses proposed in this study, the conclusions are as follows: 1). There is a positive influence between ServQual on satisfaction. This is based on the results of the parameter coefficient output. It is known that the relationship of the ServQual construct to satisfaction is significant at 0.001 (sign p = ***) with a standardized parameter coefficient of 0.735. Thus, if ServQual is good, students will be satisfied, and vice versa if ServQual is bad, students will not be satisfied. 2) There is a positive effect of satisfaction on student retention. This is based on the results of the output coefficient parameter construct relationship satisfaction to student retention significant at 0.001 (p = 0.001) and standardized parameter coefficient of 0.513. Thus if student satisfaction is high then student retention is also high, and vice versa if satisfaction is low then student retention is also low. 3) There is no influence between ServQual on student retention indicated by the output parameter coefficient at 0.001 (p = 0.132) This proves that loyalty cannot be created through service quality, but through satisfaction first. thus, it can be said that satisfaction has a mediating effect between ServQual and Student Retention.

Computational Fluid Dynamics to Assess the Blade Effect of a New Savonius Rotor for Improvement of the Output Power Coefficient

The output power coefficient of the Savonius rotor should be improved for better practical applications. So far, new Savonius rotor has been developed to improve the minimum output coefficient by adding semi-elliptical blade. Thus, the purpose of this research is to investigate the influence of the additional semi-elliptical blade’s position on the output coefficient. Flow around the rotor was simulated by using the regularized lattice Boltzmann method. The virtual flux method was used to express the shape of the rotor on a Cartesian grid, and the multi-block method was used for local fine grids of the rotor. The rotation speed of the Savonius rotor was maintained constant, and its performance was evaluated by the output power and torque coefficients. As a result, the semi-elliptical blade successfully generated additional positive torque in the range of the advancing phase and improved the minimum output power coefficient of the rotor during a cycle. When the moment arm is short, the semi-elliptical blade did not generate large negative torque in the range of the returning phase owing to its position behind the main blade in the wind flow direction. The output power coefficient of the new Savonius rotor was improved compared to that of the traditional one depending on the length of the semi-elliptical blade’s moment arm.

Cross-border Vertical Integration and Intra-firm Trade: New Evidence from Korean and Japanese Firm-level Data

This paper establishes two facts about cross-border vertical integration and intra-firm trade of firms in Korean and Japanese manufacturing industries. First, the intra-firm trade between a parent firm and its affiliates is highly concentrated in a small number of large multinational corporations. Second, the input–output coefficient between the parent firm's industry and the affiliate's industry is weakly related to the presence and magnitude of intra-firm trade between the parent firm and its affiliates. Furthermore, these two characteristics are also found in domestic vertically integrated firms. In particular, the second point identifies a need for further research on the motivation of cross-border vertical integration between two manufacturers, the final good producers at home and the input suppliers abroad.

Environmental efficiency evaluation of china based on a kind of congestion and undesirable output coefficient

The production ?congestion? phenomenon is widespread in reality although few models nowadays consider its influences. In this study, production congestion is introduced into an environmental efficiency evaluation model and a new data envelopment analysis model that considers both production congestion and undesirable output is established so as to measure environmental efficiency evaluation effectively. On this basis, we divide technological change into productive technological change and energy-savings emission reduction technological change to establish their influences on the congestion phenomenon. The results show that productive technological change cannot relieve the degree of congestion while green technology change that stimulates environmental efficiency improvement can greatly alleviate situations of congestion.
