Since 1 July 1997, consumers have the choice of preselecting their preferred long distance carrier or dialling the override code before dialing a telephone number.

Since the nodes cannot sense the carrier, Carrier sense multiple access with collision avoidance ( CSMA / CA ) does not work, and collisions occur, corrupting the data at the access point.

Since EtO is explosive from its lower explosive limit of 3 % all the way to 100 %, EtO was traditionally supplied with an inert carrier gas such as a CFC or halogenated hydrocarbon.

Since the carrier ring used in constant seating stress gaskets take this deflection into account when creating the carrier ring for a given flange size, pressure class, and material, the carrier ring profile can be adjusted to enable the gasket seating stress to be radially uniform across the entire sealing area.

Since the bankruptcy of Malev Hungarian Airlines on the 3rd of February 2012, Wizz Air can be considered as being the flag carrier of Hungary.

Since the appearance of calcification is age-dependent, a CT scan could be negative in a gene carrier who is younger than the age of 55.

Since the sale to Omniport the airport has become one of the UK hubs for budget carrier Flybe and the number of flights and destinations served have rapidly increased.

Since a carrier current station is unlicensed, and actually makes up its own call letters, the FCC granted the commercial station's request.

Since testing and debugging are often many times more costly than initial programming, this is an impressive result.

Since each user will normally have their own IP address, commercial testing products ( such as HP's Loadrunner software ) can use IP spoofing, allowing each vuser its own " return address ", as well.

Since he realized there was a difference in testing the drug in a laboratory and using it in clandestine operations, he initiated a series of experiments where LSD was given to people in " normal " settings without warning.

Since fashion models are scouted at a very young age, they spend the first couple of years making very little money as they are testing and working for lower echelon clients while developing their portfolios.

Since some people seek medical attention after only one attack, other testing may hasten and ease the diagnosis.

Since then, in its campaigns and undercover investigations, it has focused on four core issues — opposition to factory farming, fur farming, animal testing, and animals in entertainment — though it also campaigns against fishing, the killing of animals regarded as pests, the keeping of chained backyard dogs, cock fighting, dog fighting, and bullfighting.

Since the religious status of a Kohen is contingent upon being the male biological descendant of Aaron in conjunction with numerous other variables that are not subject to genetic testing ( the wife of a kohen cannot have had relations with a non-Jew, be a divorcee etc.

Since that time, many urologists will order a " Urine C & S " ( urinalysis with bacterial / fungal cultures and testing for sensitivities to anti-infective medications ) prior to the performance of the cystoscopy, and as part of the pre-operative workup.

Since the early 1970s, Fort Hood has played a major role in the training, testing, and introduction of new equipment, tactics, and organizations.

Since 1985, the U. S. military has been testing serial hybrid Humvees and have found them to deliver faster acceleration, a stealth mode with low thermal signature / near silent operation, and greater fuel economy.

Since then owner Peter Stull has been working with senior engineering students at Alfred University, local engineers and machinists utilizing available technology including computer FEA testing to improve their recumbent bikes.

Since fault coverage is important in stability testing, the tests are often run for long periods of time, hours or even days.

Since the car was damaged during the testing, and Wangers did not want anyone looking under the hood, he used the blue road course GTO to flat tow the red GTO 1500 miles back to Detroit.

Since 2005, the Melungeon DNA Project has conducted DNA testing of identified Melungeon lines.

Since debugging and testing may also require more resources than are available on an embedded system, cross-compilation can be less involved and less prone to errors than native compilation.

Since its introduction in late 2005, the Internet-based Test ( iBT ) has progressively replaced both the computer-based tests ( CBT ) and paper-based tests ( PBT ), although paper-based testing is still used in select areas.

Since genetic testing may open up ethical or psychological problems, genetic testing is often accompanied by genetic counseling.

Since a country-specific power supply cord can be included in the product packaging, model variations are minimized and factory testing is simplified.

Since detectable antibody responses require about a week after infection to develop, serologic testing may be falsely negative early in the disease course.

Since these tests are relatively expensive, the blood is screened by first pooling some 8-24 samples and testing these together ; if the pool tests positive, each sample is retested individually.

Since the early days of USAF testing, the chase aircraft have been manned by test pilots just like the experimental planes they accompany, providing a common language and bond between test pilot and observer.

Since its early statement for radiolocation, many applications have been found for inverse scattering techniques, including echolocation, geophysical survey, nondestructive testing, medical imaging, quantum field theory.

Since many long distance transmission pipelines are designed to have a steel hoop stress of 80 % of specified minimum yield ( SMYS ) at MAOP, this means that the steel is stressed to SMYS and above during the testing, and test sections must be selected to ensure that excessive plastic deformation does not occur.
