The result of the observations is Af where the phase angle, Q, is measured in degrees from new moon and the probable errors include absolute as well as relative errors.

This means that work equals Q which in turn equals Af.

The approximate equation is Af, where N is the number of Af with electron line-density greater than or equal to Af, and Q is proportional to the mass of the meteorite.

Agents that are known to cause frequent infections among laboratory workers such as those causing Q fever, tularemia, brucellosis, glanders, coccidioidomycosis, etc., belong in this category.

Therefore each binomial trial can be thought of as producing a value of a random variable associated with that trial and taking the values 0 and 1, with probabilities Q and P respectively.

On C, from the point P at Af to the point Q at Af, we construct the chord, and upon the chord as a side erect a square in such a way that as S approaches zero the square is inside C.

As S increases we consider the two free corner points of the square, Af and Af, adjacent to P and Q respectively.

With the vertex at Af in the C-plane we assume that Af is the parametric location on C of an ordinary intersection Q between C and Af.

In the C-plane we construct a set of rectangular Cartesian coordinates u, V with the origin at Q and such that both C and Af have finite slope at Q.

Near Q, both curves can be represented by analytic functions of U.

In a neighborhood of Q the difference between these functions is also a single-valued, analytic function of U.

Furthermore, one can find a neighborhood of Q in which the difference function is monotone, for since it is analytic it can have only a finite number of extrema in any interval.

Now, to find Af, one needs the intersection of C and Af near Q.

Thus if E is sufficiently small, there can be only one intersection of C and Af near Q, for if there were more than one intersection for every E then the difference between C and Af near Q would not be a monotone function.

Therefore, Af is single-valued near Q.

A tangent point Q in the C-plane occurs when C and Af are tangent to one another.

We again consider a fixed point P at Af and a variable point Q at Af on C.

We erect a square with PQ as a side and with free corners Af and Af adjacent to P and Q respectively.

Let Q be a nonsingular quadric surface bearing reguli Af and Af, and let **zg be a Af curve of order K on Q.

A general line L meets Q in two points, Af and Af, through each of which passes a unique generator of the regulus, Af, whose lines are simple secants of Aj.

We observe first that no line, l, can meet its image except at one of its intersections with Q.

Moreover, from the definitive transformation of intercepts on the generators of Af, it is clear that the only points of Q at which a line can meet its image are the points of Aj.

Perugia was an Umbrian settlement but first appears in written history as Perusia, one of the 12 confederate cities of Etruria ; it was first mentioned in Q. Fabius Pictor's account, utilized by Livy, of the expedition carried out against the Etruscan league by Fabius Maximus Rullianus in 310 or 309 BC.

For 297 the Romans elected as consuls Q. Fabius Maximus Rullianus ( consul for the 4th time ) and P. Decius Mus ( consul for the 3rd time ).

* Quintus Fabius ( Q. f. C. n .) Pictor, praetor in 189 BC, received Sardinia as his province, but was compelled by the pontifex maximus to remain at Rome, because he was Flamen Quirinalis ; his abdication was rejected by the senate, which designated him praetor peregrinus.

The first of the annalists, the father of Roman history, as he has been called, was Q. Fabius Pictor ; contemporary with him was Lucius Cincius Alimentus, who flourished during the Hannibalic war ( not to be confused with L. Cincius, the author of various political and antiquarian treatises ( de Fastis, de Comitiis, de Priscis Verbis ), who lived in the Augustan age, to which period Mommsen, considering them a later fabrication, refers the Greek annals of L. Cincius Alimentus ).
