During polymer flooding, certain amount of polymer would be lost. Polymer retention causes sweep volume expanding on one side, it also causes polymer loss on the other. Therefore, it is a very important topic to study the influencing factors of polymer retention. There are many factors affecting polymer retention process. This paper mainly studied the influence from dynamic factors such as polymer solution concentration, injection rate, injection time, injected pv number. This paper investigated the influence of these factors on polymer retention process, and optimized these factors to minimize polymer loss in reservoir.

Purpose The purpose of this paper is to measure the pattern of contract agreement process to map various banks’ position in perceiving Sharia conduct. This is done by incorporating the dynamics of culture, market demand and Sharia literacy in different banks. Finding of this research will serve as the formula to map the latent degree of Islamic bank’s commitment to their strategic vision and identity as an Islamic-based financial institution. Design/methodology/approach This research develops its theoretical background in classical and contemporary literature review on murabahah contract in Islamic perspective. Focus group discussion (FGD) and in-depth interview are conducted on 32 bankers (in 14 Islamic banks), two National Sharia Council, five academicians and three central bank representatives as an input for qualitative analysis. Content analysis is utilized in this paper to emphasize the process of discovering the relationship between dynamic factors affecting contract agreement process in murabahah scheme in Indonesian banking. Findings There are four dimensions affecting the contract agreement: fairness to customer, country regulation, perceived business practicality and product characteristic. The four dimensions are assumed to be influenced with categories proposed, as the category item is mostly repeated and is perceived to be significant in the participant’s perspective. Originality/value This research will be beneficial in mapping the determinant of degree of Sharia compliance in Sharia banking in Indonesia, focusing on the contract agreement process.

The driving force of super-gentrification shapes a complex system in which multiple dynamic factors interact with each other. This paper takes the dynamic factor system of super-gentrification as the research object and uses the Interpretative Structure Modeling (ISM) to analyze these dynamic factors. The levels of these dynamic factors and the interaction between them are determined. The Cross Impact Matrix Multiplication Applied to a Classification (MICMAC) analysis is also conducted to determine the dependence power and driving power of these dynamic factors. Through analysis, it is concluded that the dynamic factors of super-gentrification are distributed on six levels. Among these dynamic factors, Transformation of Industrial Structure and Occupational Structure in Urban Central Areas, Housing Needs of Overseas Elites, Investment Needs, Development of the Real Estate Market, and Unique Areas and Lifestyle Preferences are the fundamental dynamic factors affecting super-gentrification. The findings of this paper can enrich the existing theoretical research on the driving force of super-gentrification and can provide a reference for policy makers to promote urban landscape sustainability to some extent.

Results of calculating the sonic boom generated in a supersonic air flow by two bodies (disk and slender body of revolution) are presented. The bodies are arranged one behind the other. The slender body is aerodynamically shaded by the disk. The free-stream Mach number is 2. The calculations are performed by a combined method of “phantom bodies.” By changing the disk position and its size, it is possible to reduce the sonic boom level. Based on the calculation results, the gas-dynamic factors affecting the sonic boom level are described.
