ABSTRACT
This work pertains to current results in the development of CO2 separation membranes from flue gas streams typically found in coal-fired power plants. A versatile free-radicalbased polymerization method is employed for the development of a multifunctional block copolymer that has good affinity to CO2, is processable into and applicable as gas separation polymer membranes. In order to validate the resulting materials, thin slabs of the polymer were melt-processed, and then sorbed with CO2 and N2 in a pressure cell. When the pressure is released, foaming tendencies at the outer regions of the samples were observed. A quantitative model involving measurements of unfoamed regions is used to correlate with permeability ratios as well as CO2-polymer mutual diffusivities. One particular optimized material, called RB1-215, is shown to possess a good CO2 relative permeability to N2. Thus, the experimental methodology has been shown to possibly be able to develop the next generation of CO2 separation polymer membranes for carbon sequestration applications.

Does Immigration Promote the Investment of the Monopolistic Firm?

In the present paper, we examine the effect of increasing uncertainty of immigrants’ growth on the optimal timing of investment of a firm that has a monopolistic power over the labor market. It is revealed that when the uncertainty of immigrants’ growth is more than a threshold level, increasing uncertainty of immigrants’ growth accelerates the optimal timing of firms’ investment and enhances the economic growth, even if the uncertainty of immigrants’ growth is formulated by the geometric Brownian motion, which is in sharp contrast to the standard result that an increase in the uncertainty postpones the optimal timing. With an increase in the immigrants over the past ten years, workforces in the host countries have been growing significantly to the extent that the immigrants represent 70% of the increase in the workforce in Europe, and 47% in the United States as OECD indicates. In the present paper, we attempted to investigate the effect of increased uncertainty caused by the growi...

Education Policy Implementation: A Mechanism for Enhancing Primary Education Development in Zanzibar

Education is one of the fundamental rights of individuals; therefore, the government of a country needs to develop and strengthen educational policy and quality as well as to ensure that everyone has equal access to basic education. The improvement of access and quality of education in the world is becoming as an essential factor in development, whereas the basic education (primary school), is acknowledged as a foundation of the higher educational development for every country. To fulfill this goal, governments introduce several policies and procedures; however, it requires some reforms and participation from the politician, policymakers, and other stakeholders to re-examine educational policy so that it can lead to multiplication and betterment of the reforms. Educational reforms actually focus on accountability. A positive educational development and reform is very challenging and needs more effort and strategy on how to use and utilize the resources effectively as such it can achie...
