In finance, a day count convention determines how interest accrues over time for a variety of investments, including bonds, notes, loans, mortgages, medium-term notes, swaps, and forward rate agreements (FRAs). This determines the number of days between two coupon payments, thus calculating the amount transferred on payment dates and also the ...
Days sales outstanding. In accountancy, days sales outstanding (also called DSO and days receivables) is a calculation used by a company to estimate the size of their outstanding accounts receivable. It measures this size not in units of currency, but in average sales days. Typically, days sales outstanding is calculated monthly.
Days payable outstanding (DPO) is an efficiency ratio that measures the average number of days a company takes to pay its suppliers. The formula for DPO is: D P O = e n d i n g A / P P u r c h a s e / d a y {\displaystyle DPO={\dfrac {ending~A/P}{Purchase/day}}}
The Doomsday rule, Doomsday algorithm or Doomsday method is an algorithm of determination of the day of the week for a given date. It provides a perpetual calendar because the Gregorian calendar moves in cycles of 400 years. The algorithm for mental calculation was devised by John Conway in 1973, [1] [2] drawing inspiration from Lewis Carroll ...
The basic approach of nearly all of the methods to calculate the day of the week begins by starting from an "anchor date": a known pair (such as 1 January 1800 as a Wednesday), determining the number of days between the known day and the day that you are trying to determine, and using arithmetic modulo 7 to find a new numerical day of the week.
Doomsday Clock. The Doomsday Clock is a symbol that represents the likelihood of a human-made global catastrophe, in the opinion of the members of the Bulletin of the Atomic Scientists. [1] Maintained since 1947, the clock is a metaphor, not a prediction, for threats to humanity from unchecked scientific and technological advances.
Yttrium-90 is produced by the nuclear decay of strontium-90 which has a half-life of nearly 29 years and is a fission product of uranium used in nuclear reactors. As the strontium-90 decays, chemical high-purity separation is used to isolate the yttrium-90 before precipitation. [7] [8] Yttrium-90 is also directly produced by neutron activation ...
90 Sr decays into 90 Y which is a beta emitter with a half-life of 2.67 days. 90 Y is sometimes used for medical purposes and can be obtained either by the neutron activation of stable 89 Y or by using a device similar to a technetium cow. As the half lives of the unstable Yttrium isotopes are low (88
