No. The hepatitis B vaccine series should not berestarted when doses are delayed; rather, the seriesshould be continued from where it left off. Thevaccine recipient should receive the second doseof vaccine now and the third dose 2â5 monthslater.
The symbol used by mathematicians to represent the ratio of a circle's circumference to its diameter is the lowercase Greek letter Ï, sometimes spelled out as pi, and derived from the first letter of the Greek word perimetros, meaning circumference. In English, Ï is pronounced as pie (/paÉª/, paÉª).
PI is a truly magical number! The symbol itself is a Greek letter. It represents the number 3.14159... , a number which has an infinite number of decimal places, with no repeating pattern. (These kinds of numbers are called irrational.) Because there is no predictable pattern to the digits, we can never know all of them.
