QUES: As Muslim institutions of higher learning, the madrasa had the legal designation of waqf. In central and eastern Islamic lands, the view that the madrasa, as a charitable endowment, will remain under the control of the donor (and their descendent), resulted in a "spurt" of establishment of madaris in the 11th and 12th centuries. However, in Western Islamic lands, where the Maliki views prohibited donors from controlling their endowment, madaris were not as popular. Unlike the corporate designation of Western institutions of higher learning, the waqf designation seemed to have led to the exclusion of non-orthodox religious subjects such a philosophy and natural science from the curricula. The madrasa of al-Qarawiyin, one of the two surviving madaris that predate the founding of the earliest medieval universities and are thus claimed to be the "first universities" by some authors, has acquired official university status as late as 1947. The other, al-Azhar, did acquire this status in name and essence only in the course of numerous reforms during the 19th and 20th century, notably the one of 1961 which introduced non-religious subjects to its curriculum, such as economics, engineering, medicine, and agriculture. It should also be noted that many medieval universities were run for centuries as Christian cathedral schools or monastic schools prior to their formal establishment as universitas scholarium; evidence of these immediate forerunners of the university dates back to the 6th century AD, thus well preceding the earliest madaris. George Makdisi, who has published most extensively on the topic concludes in his comparison between the two institutions:

QUES: The key advantage of the four-rail system is that neither running rail carries any current. This scheme was introduced because of the problems of return currents, intended to be carried by the earthed (grounded) running rail, flowing through the iron tunnel linings instead. This can cause electrolytic damage and even arcing if the tunnel segments are not electrically bonded together. The problem was exacerbated because the return current also had a tendency to flow through nearby iron pipes forming the water and gas mains. Some of these, particularly Victorian mains that predated London's underground railways, were not constructed to carry currents and had no adequate electrical bonding between pipe segments. The four-rail system solves the problem. Although the supply has an artificially created earth point, this connection is derived by using resistors which ensures that stray earth currents are kept to manageable levels. Power-only rails can be mounted on strongly insulating ceramic chairs to minimise current leak, but this is not possible for running rails which have to be seated on stronger metal chairs to carry the weight of trains. However, elastomeric rubber pads placed between the rails and chairs can now solve part of the problem by insulating the running rails from the current return should there be a leakage through the running rails.

QUES: Flower ontogeny uses a combination of genes normally responsible for forming new shoots. The most primitive flowers probably had a variable number of flower parts, often separate from (but in contact with) each other. The flowers tended to grow in a spiral pattern, to be bisexual (in plants, this means both male and female parts on the same flower), and to be dominated by the ovary (female part). As flowers evolved, some variations developed parts fused together, with a much more specific number and design, and with either specific sexes per flower or plant or at least "ovary-inferior".
