In its early years, the Home Shopping Network also aired a Yule Log for the network's only non-broadcasting day before moving to a loop of Tampa Bay Area choirs singing Christmas carols and host wishes in subsequent years.

However for two weeks afterward, analog channel 28 aired a repeating loop of a short informational film ( in both English and Spanish ) about the DTV changeover and how to upgrade to digital television.

MLB Network, for example, aired a continuous loop of baseball highlights and promos as a " soft launch " in the weeks before its formal debut on January 1, 2009, while Canada's Sun News Network employed an on-screen countdown clock graphic in the hours before its April 18, 2011 launch.

At 5pm local time, NPR and local news broadcasts ended on WOSU-AM ... afterwards a continuous loop of announcements by WOSU and NPR staffers were aired asking listeners to switch over to WOSU-FM where its news and talk format continues.

From January to February 2011, the station aired a music loop directing listeners to WDDZ.

Of the potentially useful sources of ionizing radiations, gamma sources, cobalt-60, cesium-137, fission products, or a reactor irradiation loop system using a material such as an indium salt have received most attention for food-preservation systems.

The time required for the system to reach a level position is approximately inversely proportional to the servo loop gain.

In addition, the cutoff frequency for input accelerations is approximately proportional to the servo loop gain ; ;

Numbers within this block are used for various test utilities such as a ringback number ( to test the ringer when installing telephone sets ), milliwatt tone ( a number simply answers with a continuous test tone ) and a loop around ( which connects a call to another inbound call to the same or another test number ).

There was no need for the wires to be connected back together into a loop, nor the need for hubs or other devices.

He fundamentally defined his arbitrary orientation for the cell as being that in which the internal current would run parallel to and in the same direction as a hypothetical magnetizing current loop around the local line of latitude which would induce a magnetic dipole field oriented like the Earth's.

It had living quarters for people, fish tanks raising Tilapia for protein, a greenhouse watered with fish water and a closed loop sewage reclamation system that recycled human waste into sanitized fertilizer for the fish tanks.

) Base stacking effects are especially important in the secondary structure and tertiary structure of RNA ; for example, RNA stem-loop structures are stabilized by base stacking in the loop region.

This is particularly so in Sydney and Melbourne, where headways on many lines in the core of the network reach 3 – 5 minutes in peaks and 10 – 20 minutes off peak ( about 18 hours a day ) and enter an underground loop for passenger distribution in the city centre ; and where ridership per capita exceeds the sum of metro and commuter rail in comparable North American urban areas such as Toronto, Boston or the San Francisco Bay Area.

Early computer programs performed I / O by waiting in a loop for the peripheral to become ready.

He fundamentally defined his arbitrary orientation for the cell as being that in which the internal current would run parallel to and in the same direction as a hypothetical magnetizing current loop around the local line of latitude which would induce a magnetic dipole field oriented like the Earth's.

# From the hairpin loop, a DNA polymerase can then use it as a primer to transcribe a complementary sequence for the ss cDNA.

For a while hybrid cable / electric systems operated, for example in Chicago where electric cars had to be pulled by grip cars through the loop area, due to the lack of trolley wires there.

In 1963 Friedman and Schwartz proposed a positive feedback loop as a mechanism for catastrophic failures in economics: “ It happens that a liquidity crisis in a unit fractional reserve banking system is precisely the kind of event that trigger-and often has triggered-a chain reaction.

Usually coronal loops lasting for long periods of time are known as steady state or quiescent coronal loops, where there is a balance in loop energy sources and sinks ( example ).

On this diagram the work that is generated for each cycle corresponds to the area within the loop.

An electrical circuit is a special type of network, one that has a closed loop giving a return path for the current.

While he had programmed extensively in machine code in the 1950s, he was known for his low opinion of the GOTO statement in computer programming, writing a paper in 1965, and culminating in the 1968 article " A Case against the GO TO Statement ", regarded as a major step towards the widespread deprecation of the GOTO statement and its effective replacement by structured control constructs, such as the while loop.

For example, he coined the programming phrase " two or more, use a for ," alluding to the rule of thumb that when you find yourself processing more than one instance of a data structure, it is time to consider encapsulating that logic inside a loop.

During the standards committee battle over whether the " minimum trip count " for the FORTRAN 77 < CODE > DO </ CODE > statement should be zero ( allowing no execution of the block ) or one ( the " plunge-ahead " < CODE > DO </ CODE >), another facetious alternative was proposed ( by Loren Meissner ) to have the minimum trip be two — since there is no need for a loop if it is only executed once.

Most practical implementations use a loop for the west and east directions as an optimization to avoid the overhead of stack or queue management:

* Kraków, Poland, has three grand unions, one at 50 ° 3 ' 27. 42 " N 19 ° 57 ' 32. 40 " E one at 50 ° 3 ' 23. 40 " N 19 ° 56 ' 43. 63 " E and one at 50 ° 4 ' 46. 65 " N 20 ° 1 ' 38. 49 " E. There is a " Grand Circle " at Centralny Square, 50 ° 4 ' 19. 56 " N 20 ° 2 ' 14. 46 " E, the " Grand Circle " which has the same route function as a grand union and also provides a loop for all lines.

The old version of exit 37 was a partial cloverleaf that included a direct entrance to the former headquarters of the Long Island State Park Commission, and utilized eastbound re-entry to nearby exit 38, which had a north to east loop ramp, and eastbound connecting ramps to and from Sylvan Road, the frontage road along the eastbound lane of the parkway between exits 37 and 39.

The latter is an example of a slow feedback loop, which works on the order of hours to days, whereas the former works on the order of minutes.

Seven hours into the emergency, new water was pumped into the primary loop and the backup relief valve was opened to reduce pressure so that the loop could be filled with water.

After 16 hours, the primary loop pumps were turned on once again, and the core temperature began to fall.

Most FDRs record approximately 17 – 25 hours worth of data in a continuous loop.

The program, which has been two to four hours in duration, is a film loop of a yule log burning in a fireplace, with a traditional soundtrack of classic Christmas music playing in the background.

A time loop or temporal loop is a common plot device in science fiction ( especially in universes where time travel is commonplace ) in which time runs normally for a set period ( usually a day or a few hours ) but then skips back like a broken record.

One loop ends with two smaller jumps backwards, reliving the iteration's final hours a second and third time, before it fully resets.

The kinetic energy stored inside the circulating loop of projectiles is vastly greater than the amount lost to inefficiencies, so it would take many hours or even days for the velocity of the projectiles to drop enough to cause problems in supporting the tower's mass.

The round trip time for the projectiles alone provides some safety margin ; in Hyde's concept design it takes each projectile over three hours to complete one loop, so even if the projectile stream was completely cut off ( by the destruction of the top or base station, for example ) there would be some time for evacuation of the remaining tower structure and regions that might be affected by significant pieces of falling debris.

* The Tor des Geants-a 330 km loop ( including 24000 D +) of the Aosta Valley in max 150 hours.

With an entrance gate that doubles as an exit, the trail of Lake Manyara National Park is effectively a loop that can be traversed by jeep within a couple of hours that may be stretched to a few more at best, if driving slowly, to watch, observe and enjoy the diversity of flora and fauna.

Kept out of the loop with regard to the 1993 assassination attempt on former President George H. W. Bush, Myers assured the press that there would be no more news coming out of the White House hours before the United States bombed Baghdad.

These performances fall into two types: ( 1 ) an installation of several hours ' duration, with the music pieces played consecutively, with a long loop of several hours of work before repetition, and with multiple images that are shown simultaneously ; or ( 2 ) a performance, with several simultaneous works of music and film, usually lasting between one and three hours.

TSN has gradually increased the length and, in some cases, repetition of SportsCentre broadcasts such that the channel now typically carries the program for up to 13. 5 hours out of the day ( including the " morning loop " repeats of the previous night's 1: 00am ET edition ), while TSN2 typically airs repeats of either SportsCentre or SportsCentre Morning Rush for a total of nine hours a day.

But while on the road, the group talk about loop holes and then come across a ten foot gap that they think will waste 5 hours back tracking.

This loop gave passengers travelling in peak hours a more direct connection between the subway and eastbound and westbound streetcars than walking to / from the curbside stops.

For the connecting Mississauga Transit and Brampton Transit buses, commuters are required to walk a short distance to Derry Road, since most local transit routes do not enter the station bus loop, even during the rush hours.
