Class 2, stations operating on clear channels are required to cease operation or operate under nighttime restrictions beginning either at local sunset ( for daytime class 2, stations ) or sunset at the location of the dominant class 1, station where located west of the class 2, station ( for limited-time class 2, stations ).

The class 1, stations on these clear channels are protected to their 0.1-mv./m. groundwave contours against daytime cochannel interference.

With respect to skywave service rendered at night, class 1, -- A stations are the only stations permitted to operate in the United States on clear channels specified for class 1, -- A operation, and so render skywave service free from cochannel interference whereever they may be received ; ;

Since the provision of skywave service requires adequate freedom from interference, only class 1, stations are capable of rendering skywave service.

Therefore, under our longstanding allocation rules, on some of these channels no station other than the dominant ( class 1 ) -- A ) station is permitted to operate at night, so that the 1, -- A station can render service, interference free, wherever it can be received.

On the remainder of the clear channels, the dominant ( class 1 ) -- B stations are protected as described above, and the relatively small number of secondary ( class 2 ) ) stations permitted to operate on these channels at night are required to operate directionally and/or with reduced power so as to protect the class 1, stations.

Additional class 2, assignments for daytime operation can be made without causing destructive interference to the class 1, stations or to each other, and by their operation provide additional service on these channels and additional local outlets for a large number of communities.

An important class of alcohols are the simple acyclic alcohols, the general formula for which is C < sub > n </ sub > H < sub > 2n + 1 </ sub > OH.

Moreover, he also found a class of weak keys that can be detected and broken by the same attack with only 2 < sup > 4r + 1 </ sup > known plaintexts.

In computational complexity theory, BPP, which stands for bounded-error probabilistic polynomial time is the class of decision problems solvable by a probabilistic Turing machine in polynomial time, with an error probability of at most 1 / 3 for all instances.

In computational complexity theory, BQP ( bounded error quantum polynomial time ) is the class of decision problems solvable by a quantum computer in polynomial time, with an error probability of at most 1 / 3 for all instances.

Thus, during any given year ( A ) if the revenues from the residential service are $7,000,000, ( B ) if the operating expenses imputed to this class of service come to $5,000,000, and ( C ) if the net investment in ( or value of ) the plant and equipment deemed devoted to this service amounts to $30,000,000, the cost analyst will report that residential service, in the aggregate, has yielded a return of $2,000,000 or 6-2/3 per cent.

It is now known that each of the A, B, and O alleles is actually a class of multiple alleles with different DNA sequences that produce proteins with identical properties: more than 70 alleles are known at the ABO locus.

* Church, along with mathematician Stephen Kleene and logician J. B. Rosser created a formal definition of a class of functions whose values could be calculated by recursion.

Inefficiency comes not just from the fact that the device is always conducting to some extent ( that happens even with class AB, yet its efficiency can be close to that of class B ); it is that the standing current is roughly half the maximum output current ( although this can be less with square law output stage ), together with the problem that a large part of the power supply voltage is developed across the output device at low signal levels ( as with classes AB and B, but unlike output stages such as class D ).

Class-A amplifiers are often used in output stages of high quality op-amps ( although the accuracy of the bias in low cost op-amps such as the 741 may result in class A or class AB or class B, varying from device to device or with temperature ).

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.

In class-AB operation, each device operates the same way as in class B over half the waveform, but also conducts a small amount on the other half.

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 ).

Hoping to build a first class contender for future years the new team debuted in Serie B in 1929.

Each class used successively additional octets in the network identifier, thus reducing the possible number of hosts in the higher order classes ( B and C ).

Antibodies are specific proteins released from a certain class of immune cells ( B lymphocytes ).

* Is-a, a relationship where one class D is a subclass of another class B

The same restrictions apply after local sunset in the case of class 3, stations operating on regional channels, which after that time are required to operate under nighttime restrictions in order to protect each other.

With respect to other frequencies, these are designated as regional or local, and assigned for use by class 3, and class 4, stations, respectively, stations operating generally with lower power.

Such additional daytime class 2, assignments are appropriate if optimum use is to be made of these frequencies, and the Commission has over the years made a large number of them.

The few cases of clear favoritism along social-class lines are as likely as not to involve representatives of the working class on the school board who favor some such practice as higher wages for janitors rather than pay increases for teachers, and such issues are not issues of educational policy.

They are mostly upper-middle- and lower-middle-class people, with a few in the upper class.

However, there are relatively few such political constituencies, and, as has been pointed out, there is seldom a clear-cut distinction between the educational interests of one social class and those of another.

Like the other policy-making groups, these are middle class in their educational attitudes, and they attempt to act in the general public interest, as they see it.

She was succeeded by five Victoria Louise class protected cruisers, the last ' protected ', as distinct from ' armoured ' cruiser class constructed by Germany.

# the plaintiff was a member of the statute's protected class.

* Columbia class cruiser, a group of two protected cruisers used by the United States Navy, 1890 – 91

* SMS Irene, a German protected cruiser 1887-1921, one of two Irene class cruisers

Minor changes in the standard ( 2000 and 2002 ) added the idea of protected types ( similar to the concept of class in C ++) and removed some restrictions from port mapping rules.

* Ölberg, literally “ Oil mountain ”, Germany ’ s largest original working class district, is protected as a historic monument.

These building types are often made up of legacy rent controlled and rent stabilized units or may contain another protected class of tenant.

The ensuing court case Wisconsin v. Mitchell ( 1993 ) was not only one of the few high-profile cases about a hate crime perpetrated by African Americans against whites but also led to a landmark decision of the United States Supreme Court ruling that a state may consider whether a crime was committed or initially considered due to an intended victim's status in a protected class.

An amendment to the Colorado state constitution (" Amendment 2 ") that would have prevented any city, town or county in the state from taking any legislative, executive, or judicial action to recognize gay and lesbian citizens as a protected class was passed by Colorado voters in a referendum.

The devaluation enraged labour because it protected the interests of the big transnationals, such as the Belize Estate and Produce Company, whose trade in British pounds would have suffered without devaluation while it subjected British Honduras's working class, already experiencing widespread unemployment and poverty, to higher prices for goods — especially food — imported from the United States.

Such second and third class protected cruisers evolved, gradually becoming faster, better armed and better protected.

Methods are defined separately from classes, and they have no special access ( e. g. this, self, or protected ) to class slots.

Her protection scheme, inspired by the Italia class, included a full-length protected deck up to 2in thick, and a cork-filled cofferdam along her sides.

The large Imperieuse class, begun in 1881 and finished in 1886, were built as armoured cruisers but were often referred to as protected cruisers.

The next class of small cruisers in the Royal Navy, the Mersey class, were protected cruisers, but the Royal Navy then returned to the armoured cruiser with the Orlando class, begun in 1885 and completed in 1889.
