Perjumpaan Islam Dan Katolik (Upaya Mencari Akar Epistemologi Tentang Konsep Keselamatan)

Every religion has a concept of salvation based on transcendent values of the religion. Islam as a religion of revelation has the concept of salvation based on the messages contained Allah in the Qur\u27an and Hadith of the Prophet are valid. With reference to the ethical principles of Islam, the doctrine of salvation is the main point ranging in religion, with this principle, people feel the need to claim to believe and submit to the values of the revealed God. A person of faith is essentially aims to achieve safety, both in his life on earth and in the Hereafter. In the Catholic Christian religion also found a number of principles are the same theology that is taught about the importance of safety. In the book of the old covenant and new covenant be emphasized that the safety ranging point in the theology. In Islam and Catholicism, the concept of divinity is the same both believe in Almighty God (monotheism). Both believe that Isa (Jesus) and Muhammad. As the bearer of divine revelation. Although Islam to explain the concept of the deity in various contexts and meanings, while the Catholic meaning of salvation is placed in a variety of different verses, but the meaning remains the same

A Computational Study on the Effects of Molecular Structures of Di-n-butyldithiophosphate and of its Derivatives on the Stability of Their Complex Compounds with Rare-Earth Elements

The stability of complex compounds  formed from the ligand di-n-butyldithiophosphate (DBDTP) and its derivatives, with ions of rare-earth elements (REEs), such as gadolinium ion (Gd3+), is an important factor in the separation and purification processes of the elements using solvent extraction method. The complex stability is dependent, one of which, on the partial charge of the donor atom (S atom in this case) in the molecule of DBDTP or its derivatives. The more negative the partial charge of the donor atom, the more stable is the complex compound formed. The purpose of this study is to explore the effect of electron donating, and of electron withdrawing groups, as well as the effect of the structure of the butyl group in the molecules of  DBDTP and or its derivatives on the partial charge of the donor atom. The method used was the semi empirical quantum mechanical calculations, i.e. the Austin Model 1 (AM1). The results of the study showed that the electron withdrawing group of -CN had resulted in the most positive charge on the donor atom, if it is on the second carbon atom of the butyl group in the DBDTP and or its derivatives. Conversely, in the same carbon atom position, the donating electron group of -CH=CH2 had generated the most negative partial charge on the donor atom. Furthermore, the results of this study also revealed that the sec-butyl isomer produced the most negative partial charge on the donor atom, among other isomers
