Then the Radon – Nikodym theorem provides the function g, equal to the density of μ with respect to Q.

Then, the set of primes v of K not in S such that F < sub > v </ sub > ⊆ X has density

Then measuring can yield a result anywhere in the interval ( a, b ), with probability density function ; i. e., a result between y and z will occur with probability

Let H and G be Hilbert spaces of dimension n and m respectively, and Φ be a quantum operation taking the density matrices acting on H to those acting on G. Then there are matrices

Then it was installed a stage and 400 graduates of the police auxiliary entered into the field, which were located on the elements of turf protection, it was obtained a density of four people per square meter, which is the density presented at massive events.

Then the total population of the urban areas ( or localities ) in Sweden was 7, 631, 952 on an area of 5, 286. 23 km², which gives an average population density of 1, 444 / km².

Then north and south of Chaves population density increases ( 68 per km² ).

Then, upon substitution the assumed relation between pressure and density into we obtain the equation

Then, on March 14, 1991, CISM's broadcasting antenna was boosted to 10 000 watts.

Then, on August 14, 1964, power was further increased to 125, 000 watts, making it the most powerful signal west of the Mississippi River ( it was grandfathered in at that power level by the Federal Communications Commission ( FCC ), which capped stations in that part of the country at 50, 000 watts ).

Then they were given 1/2 to 1-1/2 avocados per day as a substitute for part of their dietary fat consumption.

Then March brought an 18 per cent rise in net revenues -- after operating costs.

Then the data are passed through high-performance restartable dithering engine which is used regardless of monitor bit depth, i. e. also for 24 bits per pixel colour.

Then, the electrons to be placed in the molecular orbitals are slotted in one by one, keeping in mind the Pauli exclusion principle and Hund's rule of maximum multiplicity ( only 2 electrons, having opposite spins, per orbital ; place as many unpaired electrons on one energy level as possible before starting to pair them ).

Then he became the most successful salesman in the East, earning $ 100 per week.

Then the sufficient condition for exact reconstructability from samples at a uniform sampling rate f < sub > s </ sub > ( in samples per unit time ) is:

Then the changes of angle in seconds of arc per year are:

Then it transfers to the anilox roll ( or meter roll ) whose texture holds a specific amount of ink since it is covered with thousands of small wells or cups that enable it to meter ink to the printing plate in a uniform thickness evenly and quickly ( the number of cells per linear inch can vary according to the type of print job and the quality required ).

Then they switched to an Ampex 300-3 one-half inch machine, running at 15 inches per second ( which was later increased to 30 inches per second ).

Then the net change per year in the central bank's foreign exchange reserves is sometimes called the balance of payments surplus or deficit.

Then, on February 21, 13 days after the bidding process officially began, the maximum number of coins per bidder was changed from 500 to 35.

Then is 20 weeks leave paid at a rate set by statute, which was £ 123. 06 per week in 2010.

) Then the wives responded to four questions ; the first three worth 10 points each ( on occasion, the third was still a " eHarmony. com Dimension Question "), and the fourth being a two-response bonus question, with each part worth 15 points ( couples received 15 points for getting one of the two responses right, or 30 points for both ), making for a maximum score of 75 points per couple.

Then the catcher walks away from the pitcher at 0. 5 meters per second and catches a ball every 2 seconds ( 0. 5 Hz ).

Then, per his instructions, she " blinks " and causes a recovery helicopter to show up to rescue Tony, who is so grateful that he tells her she's free.

Then in 1979 the Iranian Revolution paralysed that country's oil-industry and of oil per day were withdrawn from world supply.

Then the flow of net investment per unit of time is determined by balancing losses from having a less-than-optimal level of capital with the adjustment costs of installing new capital ; these adjustment costs in per-unit terms may be an increasing function of the speed of installation.

Then he would lease the land and allotments back from the farmer for $ 50 per acre.

Then, however, investment bank Lazard, on the behalf of Banque de France and powered by J. P. Morgan & Co., bought immense amounts of francs, causing the franc to rise again, to 15 franc per dollar.

Then in 1999, Miguel Castro and Barbara Liskov introduced the " Practical Byzantine Fault Tolerance " ( PBFT ) algorithm, which provides high-performance Byzantine state machine replication, processing thousands of requests per second with sub-millisecond increases in latency.

Then the Prime Minister Surya Bahadur Thapa convinced the king to allow Mr. B. P. Koirala to proceed to the U. S. for treatment as per recommendation from the royal physician Dr. M. R. Pandey.
