Since the middle of the 19th century, some monarchists have stopped defending monarchy on the basis of abstract, universal principles applicable to all nations, or even on the grounds that a monarchy would be the best or most practical government for the nation in question, but on local symbolic grounds that they would be a particular nation's link to the past.

* Transceivers – Since communication over a single wavelength is one-way ( simplex communication ), and most practical communication systems require two-way ( duplex communication ) communication, two wavelengths will be required ( which might or might not be on the same fiber, but typically they will be each on a separate fiber in a so-called fiber pair ).

Since its crystallization in the 1930s, computation has been primarily approached from two traditions: engineering, which seeks to build practical systems using computations ; and mathematics, which seeks to prove theorems about computation ( albeit already in the 1970s computing as a discipline was described as being at the intersection of mathematical, engineering, and empirical / scientific traditions ).

Since its launch in Paris in December 2008, Global Zero ( campaign ) has grown to 300 leaders, including current and former heads of state, national security officials and military commanders, and 400, 000 citizens worldwide ; developed a practical step-by-step plan to eliminate nuclear weapons ; launched an international student campaign with 75 campus chapters in eight countries ; and produced an acclaimed documentary film, Countdown to Zero, in partnership with Lawrence Bender and Participant Media.

Since Arvanitika is almost exclusively a spoken language, Arvanites also have no practical affiliation with the Standard Albanian language used in Albania, as they do not use this form in writing or in media.

Since reason for Aristotle is not only theoretical but practical also, he spends quite a bit of time discussing excellence of character which enable a person to exercise his practical reason ( i. e., reason relating to action ) successfully.

Since most loads contain inductance, feedback rectifiers or antiparallel diodes are often connected across each semiconductor switch to provide a path for the peak inductive load current when the switch is turned off.

Since momentary interruptions or reductions of output current may cause the cathode spot to extinguish, many rectifiers incorporate an additional electrode to maintain an arc whenever the plant is in use.

Since telephone exchanges use DC, the building's battery room is generally wired directly to the consuming equipment and floats continuously on the output of the rectifiers that normally supply DC rectified from utility power.

Since the homosexuals widely use marijuana, they do not have to be initiated.

Since the slogans have little application to reality and are sanctimonious to boot, the applause is faint even in areas of the world where we should expect to find the greatest affection for free government.

Since Rhode Island at that time did not have such sanction, his opinion was not popular.

Since the great flood of these dystopias has appeared only in the last twelve years, it seems fairly reasonable to assume that the chief impetus was the 1949 publication of Nineteen Eighty-Four, an assumption which is supported by the frequent echoes of such details as Room 101, along with education by conditioning from Brave New World, a book to which science-fiction writers may well have returned with new interest after reading the more powerful Orwell dystopia.

Since 1957, more and more trans-Atlantic passengers have been crossing by air.

Since two of these could be trustees of the college, actually it would be necessary to have the consent of only one elected official to impose a levy of millions of dollars of tax revenue.

Since appeals to morality, to humanity, and to sanity have had such small effect, perhaps our last recourse is the deterrent example.

Since that time the demands of the citizens for new and expanded services have placed financial burdens on the state which could not have been foreseen in earlier years.

Since faculty see themselves as self-employed professionals rather than as employees, enthusiasm in a common enterprise is proportionate to the sense of ownership they have in it by virtue of sharing in the decisions that govern its course.

Says NRLDA's James Wright: `` Since 1958 carriers that move material from the yard to the job site have undergone more radical changes than any of the dealer's other equipment ''.

Since there is a continual loss of micrometeoritic material in space because of the radiation effects, there must be a continual replenishment: otherwise, micrometeorites would have disappeared from interplanetary space.

Since Af and P divides Af for Af, we have Af.

A final class of exceptional lines is identifiable from the following considerations: Since no two generators of Af can intersect, it follows that their image curves can have no free intersections.

Since they are all either rented or borrowed, the requested dates for their use have to be far in advance.
