The sample includes eight countries and covers the period from 1990 to 2014. The study＇s estimations are based on data from the database WDI （World Development Indicators） of the World Bank and data from BCEAO with the view to answer to the central question posed. The study is also based on the approach of a gravity equation in panel then a stochastic frontier cost. The results suggest that the score of efficiency of WAEMU＇s external trade is very low on the one hand and the range and importing countries＇ GDP negatively influence this score while GDP of the exporting countries, the common border and common language positively influence the efficiency of external trade of that union. These results show that the different WAEMU＇s countries have an interest in establishing new trade and fiscal policies able to lead them on a long period on the path of self come growth.展开更多

The Syrian crisis impact goes beyond the waves of refugees but extended to influence the trade routes to and from Jordan through Syrian route and ports. This research aims to analyze the impact of the Syrian crisis on the Jordanian trade through the use of regression analysis and the use of dummy variable to reflect the Syrian crisis, analyzed the monthly data for the period 2005-2015. In addition, it has used other statistical methods such as records, and has been the Syrian crisis impact analysis on the volume of trade, imports, total export, re-exported, and the national exports. In spite of the lack of trade stop with Syria completely, study showed that there is a significant decline in the trade exchange between Jordan and Syria, but the Syrian crisis may affect the Jordanian imports, the trade volume, trade balance while the study did not show any trace of the Syrian crisis on the national exports. Finally, the study recommends that there are needs for analytical studies and the use of econometric models to demonstrate the impact of the Syrian crisis measures on all sectors and on the sets of Jordanian goods imported and exported.展开更多

The external mass transfer effect can be represented with a model in the form of Colburn factor JD = K Re-(1–n). The value of K and n were derived from experimental data at different mass flow rates.The experiment shows an average increment of 1.51% FFA for calcium alginate and 1.62% FFA for carrageenan after the hydrolysis took place. Based on different biopolymer material used in immobilized beads, JD = 1.674 Re-0.4 for calcium alginate and JD = 1.881 Re-0.3 for k-carrageenan were found to be adequate to predict the experimental data for external mass transfer in the reactor in the Reynolds number range of 0.2 to 1.2. The purposed model can be used for the design of industrial bioreactor and scale up. Besides, the external mass transfer coefficients for the hydrolysis of Jatropha oil reaction and the entrapment efficiency for the two biopolymer materials used were also investigated.展开更多
