The technologically most important thin amorphous film is probably represented by few nm thin SiO < sub > 2 </ sub > layers serving as isolator above the conducting channel of a metal-oxide semiconductor field-effect transistor ( MOSFET ).

Her contributions are mainly on the roles of antibodies directed against ion channel at the nerve-muscle junction in the pathogenesis of above mentioned diseases.

BBC Text also enabled channel association, the ability for the user to retain their selected television channel visible in one section of the screen whilst viewing the text service, in contrast to Ceefax, which could only be viewed as a full-screen display, or as a semitransparent overlay ( i. e. opaque blocks of colour on top of the television channel, with the black background now transparent ; not ' translucent blocks of colour with a translucent black background ') above the television picture.

Wetlands are difficult areas upon which to build housing estates, so dredging part of the wetland down to a navigable channel provides fill to build up another part of the wetland above the flood level for houses.

The difference between the avalanche diode ( which has a reverse breakdown above about 6. 2 V ) and the Zener is that the channel length of the former exceeds the mean free path of the electrons, so there are collisions between them on the way out.

The first inlet turned out to be a " very narrow and intricate channel, which ... abounded with rocks above and beneath the surface of the water ".

For example the 2. 4000 – 2. 4835 GHz band is divided into 13 channels spaced 5 MHz apart, with channel 1 centered on 2. 412 GHz and 13 on 2. 472 GHz ( to which Japan added a 14th channel 12 MHz above channel 13 which was only allowed for 802. 11b ).

Some cartridges had frequency response above 30 kHz for use with CD-4 quadraphonic 4 channel sound.

Adding any additional channels therefore needed to be done by inserting the extra signals into cable systems on nonstandard frequencies, typically either below VHF channel 7 ( midband ) or directly above VHF channel 13 ( superband ).

Should a legal distinction be necessary between a ( location ) channel as defined above and a television channel in this sense, the terms " programming service " ( e. g. ) or " programming undertaking " ( for instance, ) may be used instead for the latter definition.

## If not, send F + 1 backwards in time on channel c. Note that this results in a paradox, as the number received in step 3 above is not the same as that sent in this step.

The D4 is ( as stated above ) a 48-channel ( dual 24 channel ) channel bank chassis, which can multiplex two banks of 24 DS0 channels into 2 T1's or a single T1C.

The FM broadcasting range ( 88 – 108 MHz ) uses a channel spacing of 200 kHz, with a maximum frequency deviation of 75 kHz, leaving a 25 kHz buffer above the highest and below the lowest frequency to reduce interaction with other channels.

Another cause of intersymbol interference is the transmission of a signal through a bandlimited channel, i. e., one where the frequency response is zero above a certain frequency ( the cutoff frequency ).

Passing a signal through such a channel results in the removal of frequency components above this cutoff frequency ; in addition, the amplitude of the frequency components below the cutoff frequency may also be attenuated by the channel.

In Broadcast band frequency modulation ( FM ), subcarriers above 75 kHz are limited to a small percentage of modulation and are prohibited above 99 kHz altogether to protect the ± 75 kHz normal deviation and ± 100 kHz channel boundaries.

Passing through Spalding, where most of the flow is diverted through the Coronation flood relief channel, the town is protected by Marsh Road sluice and a sea lock to the east.

Dugdale, writing in 1662, described the Spalding channel as " a most slow course ".

James Walker reported in 1835 on further improvements, making the recommendation that the river below Spalding should be constrained between high banks, so that the scouring action of the water would dredge its own channel.

Towards the end of the Second World War, E. G. Taverner, the chief engineer for the Drainage Board, devised a plan to relieve flooding in Spalding by creating a bypass channel, and building the Greatford Cut to divert the waters of the West Glen river into the Welland upstream of Market Deeping.

The re-routing was devised by E. G. Taverner, the chief engineer for the Welland and Deepings Drainage Board, towards the end of the Second World War, and was part of a much larger project which involved the digging of the Coronation Channel, a flood relief channel to divert the Welland around the south-eastern edge of Spalding, and the construction of Fulney lock, to exclude tidal water from the upper Welland.

Henrietta was discovering in the process of writing, as the born writer does, not merely a channel for the discharge of accumulated information but a stimulus to the development of the creative powers of observation, insight and intuition.

Then the fact that the lower channel line was pierced had further forecasting significance.

When the work was finished, the river was turned back into its usual channel and the captives by whose hands the labor had been accomplished were put to death that none might learn their secret.

Although the hardware is limited to four separate sound channels, software such as OctaMED uses software mixing to allow eight or more virtual channels, and it was possible for software to mix two hardware channels to achieve a single 14-bit resolution channel by playing with the volumes of the channels in such a way that one of the source channels contributes the most significant bits and the other the least.

To store matte information, the concept of an alpha channel was introduced by Alvy Ray Smith in the late 1970s, and fully developed in a 1984 paper by Thomas Porter and Tom Duff.

It had feature limitations such as being unable to output more than one channel of sound, ( and provided fewer Envelope-shaping options ) where the BBC was capable of three-way polyphony ( plus one noise channel ) and the inability to provide teletext mode.

In practice a technique called vestigial sideband is used to reduce the channel spacing, which would be at least twice the video bandwidth if pure AM was used.

The Murray River was formed when Totyerguil the hunter speared Otjout, a giant Murray Cod, who, when wounded, churned a channel across southern Australia before entering the sky as the constellation Delphinus.

In 2009 radio market share in the Dutch speaking region was 63. 08 % for the VRT channels ( Radio 1, Radio 2, MNM, Studio Brussel and Klara, 23. 13 % for the VMMa channels ( Q-Music and Joe FM ) and 2. 65 % for the Corelio / Concentra joint venture channel ( Radio Nostalgie ).

In 2002, a new survey was carried out on board the Ifremer RV Le Suroit for BlaSON project ( Lericolais, et al., 2003 ) completed the multibeam mapping of this underwater channel fan-delta.

Bede's account of the early migrations of the Angles and Saxons to England omits any mention of a movement of those peoples across the channel from Britain to Brittany described by Procopius, who was writing in the sixth century.

Two years later, WHDH-FM was licensed, and on November 26, 1957, WHDH-TV made its début as an ABC affiliate on channel 5.

) The FCC ordered comparative hearings, and in 1969 a competing applicant, Boston Broadcasters, Inc. was granted a construction permit to replace WHDH-TV on channel 5.

Herald-Traveler Corp. fought the decision in court — by this time, revenues from channel 5 were all but keeping the newspaper afloat — but its final appeal ran out in 1972, and on March 19 WHDH-TV was forced to surrender channel 5 to the new WCVB-TV.

During these experiments, < sup > 261 </ sup > Bh was also identified in the 2n evaporation channel and it was confirmed that < sup > 262 </ sup > Bh exists as two states-a ground state and an isomeric state.

Later a mixer was built for him by Alex Rosner which let him listen to any channel in the headphones independently of what was playing on the speakers ; this became the defining feature of DJ mixers.

He instructed his naval commander, Vice-Admiral François-Paul Brueys D ' Aigalliers, to anchor in Alexandria harbour, but naval surveyors reported that the channel into the harbour was too shallow and narrow for the larger ships of the French fleet.

In April 2008, the channel was renamed " BBC News " as part of a £ 550, 000 rebranding of the BBC's news output, complete with a new studio and presentation.

The channel was named RTS News Channel of the Year in 2006 and again in 2009.

Initially it was difficult to obtain a digital satellite or terrestrial receiver without a subscription to Sky or ONdigital respectively, but now the channel forms an important part of the Freeview package of channels.
