A rapid and sensitive CZE (Capillary Zone Electrophoresis) method for pharmaceutical analysis was developed and fully validated. The active compounds: Pseudoephedrine hydrochloride (PSE), Triprolidine hydrochloride (TRI) and Paracetamol (PAR) were separated and quantitatively determined using the tris-borate 30 mM buffer at pH = 9.0 as a Background Electrolyte (BGE). The electrophoretic separation was carried out at 25 kV in an unmodified fused silica capillary of I.D. = 50 μm with a “bubble-cell” for UV detection at 210 nm and 25°C. The separation was reached in about 3 min. After calibration the method was applied for analysis of three commercially available pharmaceutical preparations. The repeatability (RSD%) of migration time (tm) was ranging between 0.47% and 0.90% and of peak areas (A) between 0.63% and 3.64%. The Limit of Detection (LOD) values was of 0.19 μg/mL, 0.31 μg/mL and 0.08 μg/mL for respectively PSE, TRI and PAR. The results obtained in this study showed that the proposed method was useful in routinely analysis of pharmaceuticals.

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...
