Context and question: Madaris were largely centred on the study of fiqh (Islamic jurisprudence). The ijazat al-tadris wa-al-ifta' ("licence to teach and issue legal opinions") in the medieval Islamic legal education system had its origins in the 9th century after the formation of the madhahib (schools of jurisprudence). George Makdisi considers the ijazah to be the origin of the European doctorate. However, in an earlier article, he considered the ijazah to be of "fundamental difference" to the medieval doctorate, since the former was awarded by an individual teacher-scholar not obliged to follow any formal criteria, whereas the latter was conferred on the student by the collective authority of the faculty. To obtain an ijazah, a student "had to study in a guild school of law, usually four years for the basic undergraduate course" and ten or more years for a post-graduate course. The "doctorate was obtained after an oral examination to determine the originality of the candidate's theses", and to test the student's "ability to defend them against all objections, in disputations set up for the purpose." These were scholarly exercises practised throughout the student's "career as a graduate student of law." After students completed their post-graduate education, they were awarded ijazas giving them the status of faqih 'scholar of jurisprudence', mufti 'scholar competent in issuing fatwas', and mudarris 'teacher'.
When did Islamic law school begin?
Answer: 9th century
Context and question: With advances in medicinal chemistry, most modern antibacterials are semisynthetic modifications of various natural compounds. These include, for example, the beta-lactam antibiotics, which include the penicillins (produced by fungi in the genus Penicillium), the cephalosporins, and the carbapenems. Compounds that are still isolated from living organisms are the aminoglycosides, whereas other antibacterialsfor example, the sulfonamides, the quinolones, and the oxazolidinonesare produced solely by chemical synthesis. Many antibacterial compounds are relatively small molecules with a molecular weight of less than 2000 atomic mass units.[citation needed]
What are the type of antibiotics which are taken from still living things?
Answer: aminoglycosides
Context and question: The name of the metal was probably first documented by Paracelsus, a Swiss-born German alchemist, who referred to the metal as "zincum" or "zinken" in his book Liber Mineralium II, in the 16th century. The word is probably derived from the German zinke, and supposedly meant "tooth-like, pointed or jagged" (metallic zinc crystals have a needle-like appearance). Zink could also imply "tin-like" because of its relation to German zinn meaning tin. Yet another possibility is that the word is derived from the Persian word seng meaning stone. The metal was also called Indian tin, tutanego, calamine, and spinter.
Why is it possible that the name zinc could be derived from the German zinn?
Answer:
imply "tin-like"
