A long-lasting controversy : Western democracy promotion in Jordan

Since the end of the cold war and, in particular, the Al Qaeda attacks of 11 September 2001 in the United States, Western governments have in their rhetoric stressed democratization in the Middle East and North Africa (MENA) region as a key policy goal. 1 The EU, the US and other Western countries have developed and extended their democracy promotion activities in the region, in particular democracy assistance to civil society, independent media, the judiciary, parliament and political parties. 2 Such assistance has at times been complemented with public criticism of perceived non-democratic behaviour and political conditionalities, i.e. making democratic reform a precondition for granting favours such as trade deals and development assistance.peer-reviewe

A Preliminary study of removal of some heavy metals from aqueous medium by a mesoporous hydroxysodalite zeolite prepared from basalt rich in calc-plagioclaseby alkali activation

This work presents an exploration of the use of hydroxysodalite zeolite prepared from basalt rich in calc-plagioclaseby alkali activation for removal of some heavy metals from aqueous medium. The preliminary results of batch and column experiments indicated a quantitative and fast removal of the three investigated ions, Cu2+, Pb2+ and Zn2+ from aqueous solutions. The data from the batch experiments and the column experiments jointly support the notion that hydroxysodalite zeolite prepared from basalt rich in calc-plagioclase is an efficient adsorbent for the investigated heavy metals.  Almost quantitative removal of the ions was achieved within a period of 15 min of exposure of the solution to the adsorbent in batch experiments and through passing a small column filled with the adsorbent. The highest removal efficiency  by the zeolite prepared from basalt rich in calc-plagioclase of  the three tested heavy metal Cu2+, Pb2+ and Zn2+ were 99.98% ,99.76% and 99.93 % respectively.
