121 Anthemios of Tralles
SUBJECT AREA: Architecture and building[br]fl. sixth century AD Tralles, Lydia, Asia Minor[br]Greek architect, geometer, mathematician and physicist.[br]Tralles was a wealthy city in ancient Greece. Ruins of the city are situated on a plateau above the present-day Turkish city of Aydin, in Asia Minor, which is near to Ephesus. In 334 BC Tralles was used as a base by Alexander the Great and later it was occupied by the Romans. After the collapse of the western half of the Roman Empire in the fifth century AD Tralles remained a part of the Byzantine Empire until its destruction in 1282. Anthemios was one of the great sons of Tralles and was probably educated in Alexandria. He is especially famed as architect (with Isodorus of Miletos) of the great Church of Santa Sophia in Istanbul. This vast building, later a Turkish mosque and now a museum, was built for the Emperor Justinian between 532 and 537 AD. It was an early and, certainly for many centuries, the largest example of pendentive construction to support a dome. This form, using the spherical triangles of the pendentives, enabled a circular-based dome to be supported safely upon piers that stood on a square plan below. It gradually replaced the earlier squinch type of structure, though both forms of design stem from Middle Eastern origins. At Santa Sophia the dome rises to 180ft (55m) above floor level and has a diameter of over 100ft (30m). Together with Isodorus, Anthemios also worked upon the Church of the Holy Apostles in Istanbul.[br]Further ReadingG.L.Huxley, 1959, Anthemius of Tralles: A Study in Later Greek Geometry, Cambridge, Mass.: Harvard University Press.Procopius, 1913, De Aedificiis, On the Buildings Constructed by the Emperor Justinian, Leipzig.Richard Krautheimer, 1965, Early Christian and Byzantine Architcture, Penguin.DY -
122 Coffey, Aeneas
SUBJECT AREA: Chemical technology[br]b. 1779/80 Englandd. 26 November 1852 Bromley, England[br]English inventor of the Coffey still for fractional distillation.[br]As Surveyor and Inspector General of Excise in Ireland, Coffey was responsible for the suppression of the illicit distilling of alcohol. In 1818 he published a pamphlet refuting charges of oppression and brutality brought against him by Irish revenue officers. He seems to have hunted with the hounds, for as a distiller himself in Dublin, he patented in 1831 the improved form of still that bears his name. The still was quickly adopted by the whisky industry as it accomplished in a single operation what had previously required several stages using the old pot stills. It is still used in the making of potable spirits, and consists of two adjacent columns, an analyser and a rectifier. Steam is passed through the liquor in the analyser, which removes the volatile fraction, and is then fractionally condensed in the rectifier column; almost pure alcohol could be produced by this means.[br]Further ReadingE.J.Rothery, 1968, Annals of Science 24:53.LRD -
123 γαζοφυλάκιον
γαζοφυλάκιον, ου, τό (v.l. γαζοφυλακεῖον N25 but-φυλάκιον preferred by B-D-F §13; s. DELG s.v. φύλαξ)① a place for the storing of valuables, treasure room, treasury (Diod S 9, 12, 2; Strabo 7, 6, 1; OGI 225, 16; Esth 3:9; 1 Macc 3:28). In this sense our sources of information on the Jerusalem temple speak of γαζοφ. in the pl. (2 Esdr 22: 44; Jos., Bell. 5, 200; 6, 282) and sg. (1 Macc 14:49; 2 Macc 3:6, 24, 28, 40; 4:42; 5:18; 2 Esdr 23: 5, 7; Jos., Ant. 19, 294). It can be taken in this sense J 8:20 (sing.) in (or at) the treasury (for the use of ἐν in the sense of ‘near’ [the public would of course not be permitted in the treasure room(s)] see s.v. ἐν 1c. But it is quite prob. that J may be using the term γ. loosely of the area generally known as the ‘treasury’, which would have the equivalent of a vault; the prep. would then be used in its customary locative sense).② For Mk 12:41, 43; Lk 21:1 the mng. contribution box or receptacle is attractive. Acc. to Mishnah, Shekalim 6, 5 there were in the temple 13 such receptacles in the form of trumpets. But even in these passages the general sense of ‘treasury’ is prob., for the contributions would go the treasury via the receptacles.—Billerb. II 37–46.

Рис. ABBThe AC mains voltage is transformed to a lower level, rectified and smoothed by capacitor C1. Then, voltage regulation is performed, typically using a power transistor. The power transistor acts as a variable resistor, controlled to keep the output voltage constant.
The efficiency of linearly regulated power supplies is only approx. 50 % due to the high losses inside the power transistor. The remaining energy is emitted in the form of heat. Due to this, sufficient ventilation is required to cool the power supply. Compared with unregulated power supplies, linearly regulated power supplies have a very small residual ripple of the output voltage (in the dimension of millivolts).
Linearly regulated power supplies are used for all applications that require a very exact output voltage, e.g. for highly precise medical devices.

Although this is an inheritance from Latin, it has been criticized by many who say it “makes women invisible”. However, unless one explicitly uses both forms in full (“ellos y ellas” or “alumnos y alumnas” etc), the rules of grammar dictate the choice. In recent years, however, an informal alternative has emerged using the “\@” symbol, and this has become especially popular on the Internet. Thus “hola a tod\@s” (hello everyone) can stand for “todos” and “todas”. This usage has been criticised and has yet to migrate into formal written contexts, and there is no spoken equivalent (other than the wordy “hola a todos y todas”), but it is a sign that even in a gender-inflected language like Spanish there are moves to get round gender stereotyping.* * *f INFOR at sign, \@;josé arroba … josé at …* * *arroba nf: arroba (Spanish unit of measurement) -
