Some 45 frequencies are assigned for use primarily by dominant Class 1, -- A or Class 1, -- B clear-channel stations, designed to operate with adequate power and to provide service -- both groundwave and ( at night ) skywave -- over large areas and at great distances, being protected against interference to the degree necessary to achieve this objective.

; METALLOENZYME, Molecular Class B ( not inhibited by clavulanic acid )

Class AB is widely considered a good compromise for audio amplifiers, since much of the time the music is quiet enough that the signal stays in the " class A " region, where it is amplified with good fidelity, and by definition if passing out of this region, is large enough that the distortion products typical of class B are relatively small.

Class B has a maximum theoretical efficiency of π / 4.

Class AB sacrifices some efficiency over class B in favor of linearity, thus is less efficient ( below 78. 5 % for full-amplitude sinewaves in transistor amplifiers, typically ; much less is common in class-AB vacuum-tube amplifiers ).

Emulsifying agents are effective at extinguishing fires on small, thin-layer spills of flammable liquids ( Class B fires ).

* New York State classifies felonies by letter, with some classes divided into sub-classes by Roman numeral ; classes range from Class E ( encompassing the least severe felonies ) through Classes D, C, B, and A – II up to Class A – I ( encompassing the most severe ).

Class A ( Rhodopsin-like ), Class B ( Secretin-like ), Class C ( Glutamate Receptor-like ), Others ( Adhesion ( 33 ), Frizzled ( 11 ), Taste type-2 ( 25 ), unclassified ( 23 )).

* Class B ( or 2 ) ( Secretin receptor family )

; Class B: Can be connected to GPRS service and GSM service ( voice, SMS ), but using only one or the other at a given time.

Most GPRS mobile devices are Class B.

Because the protocol has no field for a subnet mask, the router assumes that all subnetwork addresses within the same Class A, Class B, or Class C network have the same subnet mask as the subnet mask configured for the interfaces in question.

In order to make defective units obvious, glass units are designed with Class B construction, so that an overvoltage causes a puncture arc through the glass instead of a flashover.

A Class B mandate granted the right to administer the territories.

The second group of mandates, or Class B mandates, were all former Schutzgebiete ( German territories ) in West and Central Africa which were deemed to require a greater level of control by the mandatory power: "... the Mandatory must be responsible for the administration of the territory under conditions which will guarantee freedom of conscience and religion.

The Class B mandates were:

A Class B ( any school bus ), C ( any urban-transit-vehicle or highway-coach ), or D ( heavy trucks other than tractor-trailers ) license enables its holder to drive any truck-trailer combination with a registered-or actual-gross-vehicle-weight ( i. e., including towing-and towed-vehicle ) greater than 11 tonnes, that includes one trailer weighing no more than 4. 6 tonnes.

An example of airspace where CVFR is common would be Canadian Class B airspace.

Class A amplifiers are very inefficient, in the range of 10 – 20 % with a max efficiency of 25 % for direct coupling of the output.

Modern Class AB amplifiers commonly have peak efficiencies between 30 – 55 % in audio systems and 50-70 % in radio frequency systems with a theoretical maximum of 78. 5 %.

Commercially available Class D switching amplifiers have reported efficiencies as high as 90 %.

Amplifiers of Class C-F are usually known to be very high efficiency amplifiers.

* Class D audio amplifiers, white paper-pdf

Of the two kinds of RF power amplifier, switching amplifiers ( Class D amplifiers ) cost less and use less battery power than linear amplifiers of the same output power.

For example, class AB amplifiers are around 25 or 50 % efficiency while Class D amps are much higher ; around 80 % or more efficiency.

Since an 800 watt amplifier built with standard Class AB technology would be very heavy, some acoustic amplifier manufacturers use lightweight Class D amplifiers, which are also called " switching amplifiers.

Since an 800 watt amplifier built with standard Class AB technology would be very heavy, some acoustic amplifier manufacturers use lightweight Class D amplifiers, which are also called " switching amplifiers.

Post World War II, the majority of valve power amplifiers are of the Class AB-1 " push pull " ultralinear topology, or lower cost single ended i. e. 6BQ5 / EL84 power tubes, but niche products using the DH-SET and even OTL topologies still exist in small numbers.

In the 1970s and 1980s, most PA amplifiers were heavy Class AB amplifiers.

In the late 1990s power amplifiers in PA applications have became lighter, smaller, more powerful and more efficient due to increasing use of switching power supplies and Class D amplifiers, which offer significant weight and space savings as well as increased efficiency.

Or a bored dog because you are more interested in something else -- maybe the way you look, or the date you have after the Class, or you are just doing this to please the parents.

* Class I agents have the most potent negative inotropic effect and may cause heart failure.

Class treatment may not improve the efficiency of a mass tort because the claims frequently involve individualized issues of law and fact that will have to be re-tried on an individual basis.

The preamble to the Class Action Fairness Act stated that some abusive class actions harmed class members with legitimate claims and defendants that have acted responsibly ; adversely affected interstate commerce ; and undermined public respect for the country's judicial system.

" Although Marrow may have been using some artistic license in describing his bank robbing exploits, he also stated he was glad the United States justice system has a statute of limitations, which had likely expired when Marrow admitted to his involvement in multiple Class 1 Felonies in the early-to mid-1970s.

The Finnish State Railroad is planning to phase out the Soviet-manufactured VR Class Sr1 engines, operative since 1973, in 2024, at which time they will have been over fifty years in line service.

The first group, or Class A mandates, were territories formerly controlled by the Ottoman Empire that were deemed to "... have reached a stage of development where their existence as independent nations can be provisionally recognized subject to the rendering of administrative advice and assistance by a Mandatory until such time as they are able to stand alone.

Some stories have been written with a proverb overtly as an opening, such as " A stitch in time saves nine " at the beginning of " Kitty's Class Day ", one of Louisa May Alcott's Proverb Stories.

Class issues are a strong component of screwball comedies: the upper class tend to be shown as idle and pampered, and have difficulty getting around in the real world.

" Ironically ( because, it appears, no one had noticed his allusion ) Sonata No. 7 received a Stalin Prize ( Second Class ), and No. 8 a Stalin Prize First Class, even though the works have been subsequently interpreted as representing Prokofiev " venting his anger and frustration with the Soviet regime.

In America, however, where there is no aristocracy or royalty, the Upper Class status belongs to the extremely wealthy, the so-called ' super-rich ', though there is some tendency even in America for those with old family wealth to look down on those who have earned their money in business.

In general a game must have all characteristics of a Class II game to be a Class II game.

Helped to escape on the night before his execution by Garth, Devon convinces Rachel and Garth to come with him and after making their way to the bridge they have found that it had been damaged and its control systems made in-operative, the crew killed ( a few skeletal bodies are lying there ) and the ARK is on a collision course with a Class G star similar to the Sun.

A friend of Williams suggested that Williams see the advisor of the Governor's Selective Service Appeal Agent, since Williams was the sole support of his mother, arguing that Williams should not have been placed in Class 1-A, and said Williams should be reclassified to Class 3-A.

The Portland GMB also hosts many social and educational events, notably Music for the Working Class, a free event that occurs on the last Wednesday of every month at the Red and Black Cafe, 400 SE 12th St. Acts that have appeared include Brendan Phillips and Fast Rattler, David Rovics, and the unofficial band of the Portland branch, I Wobble Wobble.

Both have a minimum of two lanes in each direction, but Class A has grade separated interchanges, while Class B has at-grade intersections.
