Ex: A musical adaptation is a musical work that represents a distinct alteration of another work (e.g. a free transcription), a work that paraphrases parts of various works or the general style of another composer, or a work that is merely based on other music (e.g. variations on a them).Ex: These changes have meant modifications, some very time-consuming, to serials catalogues in libraries.Ex: To ensure further that all the index entries generated by chain procedure are indeed helpful, the initial analysis of the chain may require editing.Ex: There is little modulation, whole steps of division being short-circuited and an odd assembly of terms being frequently found: e.g.: LAW see also JURY, JUDGES.Ex: Better flexibility is achieved if the heating, ventilation and lighting can accommodate this move without the need for any alterations.Ex: This kind of large-scale recasting offers an opportunity for the scheme to go forward rather than stagnate until it is completely taken by events.Ex: This action was the redesign of the enquiry form in order to elicit more information from the enquirer.Ex: The entries that result from the rotation mechanism have standard layout, punctuation and typography, all of which have been pre-programmed.Ex: Transitory circumstances of daily life are what cause these shifts.Ex: When the record transfer is complete, the catalog summary screen is shown for the new record so that the user can review and update it.Ex: Hungary faces far-reaching socio-economic transformation which will inevitably affect libraries as well.Ex: The changeover has resulted in more rapid machine-editing of input and reduced costs for cataloguing.Ex: A centralised system was chosen to ensure speedy receipt and dissemination with minimal disturbances.Ex: The very meanings of words like 'library' and 'university' are about to undergo mutations too radical to conceive, much less predict = Los significados mismos de palabras como "biblioteca" y "universidad" están a punto de experimentar cambios demasiado radicales de concevir y cuanto mucho menos de predecir.Ex: There is greater permeability than before between different types of library at the start of a career but, once settled in a post, fewer librarians than before change from one type of library to another.Ex: The author presents suggestions for the reformation of medical library education.Ex: The transition date for the switchover is 1 Oct 2000.Ex: Moreover, we conclude that the process of placing a feminist stamp on working relations is both far from complete and subject to reverses.Ex: This article discusses the effects of changes in the economy on the distribution of work in libraries which indicate a shift away from its female origins.Ex: This article considers the use of a spreadsheet in the shifting of periodicals collections in order to save time.Ex: The recent reorganization has resulted in a merger of the academic and public divisions and a changing of the guard among the company's top officials.Ex: The addition of new feedback techniques produced a significant swing in favour of the application.Ex: Holdings will become increasingly important as a bartering tool to gain additional access benefits.Ex: Office automation have brought about a switch to a paperless office.Ex: These 'spuriously loyal' customers are not willing to churn just because of switching costs.Ex: Most libraries maintain a small cash float for the giving of change and, in addition, money/ is received in payment of fines.* a cambio = in

3 Bain, Alexander
[br]b. October 1810 Watten, Scotlandd. 2 January 1877 Kirkintilloch, Scotland[br]Scottish inventor and entrepreneur who laid the foundations of electrical horology and designed an electromagnetic means of transmitting images (facsimile).[br]Alexander Bain was born into a crofting family in a remote part of Scotland. He was apprenticed to a watchmaker in Wick and during that time he was strongly influenced by a lecture on "Heat, sound and electricity" that he heard in nearby Thurso. This lecture induced him to take up a position in Clerkenwell in London, working as a journeyman clockmaker, where he was able to further his knowledge of electricity by attending lectures at the Adelaide Gallery and the Polytechnic Institution. His thoughts naturally turned to the application of electricity to clockmaking, and despite a bitter dispute with Charles Wheatstone over priority he was granted the first British patent for an electric clock. This patent, taken out on 11 January 1841, described a mechanism for an electric clock, in which an oscillating component of the clock operated a mechanical switch that initiated an electromagnetic pulse to maintain the regular, periodic motion. This principle was used in his master clock, produced in 1845. On 12 December of the same year, he patented a means of using electricity to control the operation of steam railway engines via a steam-valve. His earliest patent was particularly far-sighted and anticipated most of the developments in electrical horology that occurred during the nineteenth century. He proposed the use of electricity not only to drive clocks but also to distribute time over a distance by correcting the hands of mechanical clocks, synchronizing pendulums and using slave dials (here he was anticipated by Steinheil). However, he was less successful in putting these ideas into practice, and his electric clocks proved to be unreliable. Early electric clocks had two weaknesses: the battery; and the switching mechanism that fed the current to the electromagnets. Bain's earth battery, patented in 1843, overcame the first defect by providing a reasonably constant current to drive his clocks, but unlike Hipp he failed to produce a reliable switch.The application of Bain's numerous patents for electric telegraphy was more successful, and he derived most of his income from these. They included a patent of 12 December 1843 for a form of fax machine, a chemical telegraph that could be used for the transmission of text and of images (facsimile). At the receiver, signals were passed through a moving band of paper impregnated with a solution of ammonium nitrate and potassium ferrocyanide. For text, Morse code signals were used, and because the system could respond to signals faster than those generated by hand, perforated paper tape was used to transmit the messages; in a trial between Paris and Lille, 282 words were transmitted in less than one minute. In 1865 the Abbé Caselli, a French engineer, introduced a commercial fax service between Paris and Lyons, based on Bain's device. Bain also used the idea of perforated tape to operate musical wind instruments automatically. Bain squandered a great deal of money on litigation, initially with Wheatstone and then with Morse in the USA. Although his inventions were acknowledged, Bain appears to have received no honours, but when towards the end of his life he fell upon hard times, influential persons in 1873 secured for him a Civil List Pension of £80 per annum and the Royal Society gave him £150.[br]Bibliography1841, British patent no. 8,783; 1843, British patent no. 9,745; 1845, British patent no.10,838; 1847, British patent no. 11,584; 1852, British patent no. 14,146 (all for electric clocks).1852, A Short History of the Electric Clocks with Explanation of Their Principles andMechanism and Instruction for Their Management and Regulation, London; reprinted 1973, introd.
