Accounting and Auditing Organization for Islamic Financial Institutions （AAOIFI）, as an international standard-setting organization for Islamic finance, raised an issue that 85% issuances of Musharakah and Mudharabah sukuk have breached the shariah rulings and do not comply with Islamic principles （AAOIFI, 2002）. Consequently, the performance of equity-based sukuk in Malaysia was affected. This study used a secondary data for size of issuances which are gathered from Bank Negara Malaysia （BNM）＇s Bond Info website and Securities Commission （SC） website. The performance of equity-based sukuk, either Musharakah or Mudarabah, is robust in the study year period of 2000-2012 as regards their sizes of issuances.展开更多

After systematic evaluation of the theoretical results against available experimental C-I BDEs, it was found that the MPW LYPIM method gave the lowest root mean square error. We, therefore, used this method to examine the substituent effects on different categories of C（sp3）-I and C（sp2）-I bonds. Fur thermore, the remote substituent effects on the C-I BDEs of substituted iodobenzenes and substituted （iodomethyl）benzenes were also investigated at the same level. The C-I BDEs of typical heteroaromatic iodides including five-membered and six-membered heterocyclic iodides were also examined.展开更多

The calculated results agree well with the experimental value, indicating that the analytic bond-order potential is suitable to describe the structural properties and surface energies of the FePt alloy in the L10 phase. However, the calculated vacancy formation energy of an Fe atom is higher than that of a Pt atom, which disagrees with some other previously calculated results. This result indicates that the analytic bond-order potential is unable to describe the related point defect properties. The analytic bond-order potential needs to be modified in order to study these defect properties of an FePt alloy.展开更多
