The Unprecedented Reactivity of Ammine-Ligated Iridium Corroles
No full textrequirement mandating a six-month period of study in a foreign lab. During that time, we worked extensively on two main projects: one, the briefer, involved the development of an optimized synthesis of H3tpfc, and mostly acted as a facilitator of our inorganic research by allowing us to produce unprecedentedly large amounts of corrole at once; the other project, which will be discussed here, began with an idea for the development of high-valent nitridoiridium corroles and ended with the synthesis of a novel porphyrinoid molecule. Throughout the course of this research project, I was introduced to a number of new techniques, including the safe use of corrosive gasses (ammonia in particular) and a battery of 2D NMR experiments. Atif Mahammed, a postdoctoral fellow in Zeev Gross ’ lab, was instrumental in developing some of the initial synthetic procedures which eventually led us to the formation of our new porphyrinoids. Additionally, David Vandervelde and Scott Virgil, two Caltech staff scientists, contributed important expertise to the project. David introduced me to a number of useful 2D NMR experiments, and Scott allowed Theis to use his HPLC for a very long and messy separation. 7
الطب النبوي وقواعد التعامل مع الأحاديث الواردة في المسائل الطبية Kacem Hadj Mahammed
No full text مستخلص يتناول هذا المقال موضوع الطب النبوي الذي شاع استعماله في السنين الأخيرة وأصبح محل دراسات ومؤتمرات علمية كثيرة. وقد تعددت وتباينت حوله الآراء: بين إنكار مطلق له، واعتداد كامل به ودفاع عنه باعتبار نسبته إلى الرسول عليه السلام. وقد عرض الباحث لبيان مفهوم الطب النبوي وذكر ووصف أهم الكتب المؤلفة فيه، كما ناقش وحلل طائفة من الضوابط الواجب الاحتكام إليها عند تناول أحاديث الطب النبوي أو الاستدلال بها في المسائل الطبية.وبناءً على ذلك خلص البحث إلى نتيجتين أساسيتين هما: أولاً أن الطب النبوي أمرٌ لا يمكن إنكاره جملة وتفصيلاً حيث دلت بعض البحوث العلمية على صحة ما ورد فيه؛ ثانيًا أنه لا ينبغي اعتباره وحيًا معصومًا ينبغي الأخذ بكل ما فيه، وأن النبي عليه السلام في هذا المجال يحدث بحكم كونه بشرًا لا بكونه نبيا.الكلمات المفتاحية: الطب النبوي، الرسول عليه السلام، الوحي، قواعد وضوابط. AbstractThe present article revolves around the subject of Prophetic medicine which has become both widely practiced and a theme of a large number of studies and conferences in recent years. Different views on it have appeared that range between total rejection and absolute reckoning and defense thereof by virtue of its attribution to the Prophet peace be upon him. Thus, the article looks into the concept and meaning of Prophetic medicine and lists out and describes the most important books written on it. Then, it discusses and analyzes a set of rules and parameters that need to be observed when dealing with medicine-related Prophetic traditions and using them in arguments on medical issues. Accordingly, the author has arrived at the following two crucial conclusions: the first is that Prophetic medicine cannot be dismissed outright en bloc, since medical research has confirmed the validity of some of its contents. Second, it cannot be considered as infallible revelation that should be literally obeyed and that on such matters of health and medicine the Prophet speaks not in his capacity as conveyor of divine revelation but out of his human experience.Keywords: Prophetic medicine, the Prophet, revelation, rules and parameters. AbstrakArtikel ini berkisar tentang topik perubatan Nabawi yang menjadi amalan meluas dan merupakan tajuk sebahagian besar kajian dan persidangan pada tahun-tahun kebelakangan ini.Pelbagai pandangan dan perbezaan pendapat muncul, iaitu antara penolakan, penerimaan mutlak dan pembelaan yang bersandarkan nilai rujukan kepada Nabi (SAW).Artikel ini melihat kepada konsep dan maksud perubatan Nabawi di samping menyenaraikan dan menerangkan karya penting yang ditulis dalam bidang ini.Ia juga membincangkan dan menganalisis kaedah-kaedah dan parameter yang perlu ada semasa berurusan dengan hadith berkaitan dengan perubatan dan penggunaannya sebagai hujah dalam isu-ini.Penulis menemui dua dapatan penting: pertama, perubatan Nabawi tidak boleh ditolak secara total kerana penyelidikan perubatan sudah mengesahkan kesahihan beberapa kandungannya.Kedua, ia tidak boleh dianggap sebagai wahyu yang maksum yang perlu diterima sepenuhnya, apatah lagi perkara-perkara berkaitan kesihatan dan perubatan Nabi tidak bercakap atas kapasiti sebagai rasul penyampai wahyu tetapi berdasarkan pengalaman manusia.Kata kunci: Perubatan Nabawi, Rasulullah, wahyu, kaedah-kaedah dan parameter.
