الرّسم العثماني وأثره على المعاني القرآنية

The Holy Qur’an is miraculous in its words, methods, organization, statements, drawings and writing, as cited and agreed by all researchers, we aim through this research to: define the Ottoman drawing in Arabic language, terminologically, demonstrating its benefits, the rule of commitment to it, weighing between sayings, demonstrating its six rules, explaining and discussing the differences between the Quranic words drawings and mentioning several examples. The most important results of this research are: 1- The opinion which comforts one's self is the commitment to Ottoman drawing, and not to be written by modern spelling methods. 2- The Ottoman drawing has multiple benefits and advantages, which are not available in any other, so that it attracts commitment and reservation. 3- It has a very significant concurrence between the drawing and the meaning of the words and verses of Quran. 4- The Qura’nic word drawing strengthens the meaning and gives the full dimensions; achieving the honesty of Allah's saying: "and whose words can be truer than those of Allah?". 5- The letters' contiguity of Quranic word, knowing its characteristics embodies the meaning with the best picture. 6- The miracle of Ottoman drawing is a modern issue that Abdalaziz Ad-Dabbagh calls the most famous and the oldest one who declared this.        The most important recommendations made in this article are: 1- Conducting more researches about the benefits of Ottoman drawing, where it still needs more studies to be conducted, and more thoughts and meditations. 2- The spread of Ottoman drawing commitment culture between Quran teachers and students. 3- Obligating all Quranic associations that adopts Quran writing to write in Ottoman drawing, and prevent any other forms of writing. 4- Obligating all students and researchers to depend on Ottoman drawing through their studies and researches; which establishes a promotion to spread its culture. 5- Guiding the researchers for more studies on this topic, throughout a focused studies and clear scientific plans.

Synthesis and Characterization of Palladium Ii Complexes With Thioureas, Heterocyclic Thiones and Phosphine Derivatives

The interaction of thioureas with metal ions has been the subject of numerous recent investigations because of their variable binding modes and because of the relevance of their binding sites to those in living systems. The complexes of palladium(II) in this regard are particularly important because of its similarity to platinum(II) complexes. Forty palladium compounds of formula [Pd(L1)2(L2)2]Cl2, where L1 = thioureas (Tu), Methylthiourea (Mtu), dimethylthiourea (Dmtu), tetramethylthiourea (Tmtu), 2-mercaptopyridine (2Mpy) and 2-mercaptopyrimidine, 6-mercaptopurine and 4-mercaptopyrimidine, L2 = Tri-p-tolylphosphine, Tri-o-tolylphosphine, Benzyldiphenylphosphine, Tris-4-chlorophenylphosphine and cyclohexyldiphenylphosphine have been synthesized by the reaction of K2[PdCl4] to phosphine and after that thiones ligands. The complexes (1), (2) and (3) were also characterized by single crystal X-ray diffraction technique. The spectral and crystallographic data suggest that the complexes show sulphur coordination of thioureas/heterocyclic thiones and phosphorous coordination of phosphines to palladium(II). The geometry of palladium(II) is distorted square planar. The antibacterial activities against bacterial strains were checked using Imipenum as reference. The antitumor ability for MCF7 tumor cell line was found comparable to that of doxorubicin. The investigated compounds have shown a relatively less cytotoxic effect in brine shrimp bioassay study. The antioxidant activity indicate potential for further study. The results designate that palladium complexes with thiones and phosphines ligands should be studied further for their use as anticancer palladium drugs in future.
