What is the difference between principal investigator and co-investigator?
A Co-Investigator is an individual recognized by the Institute and the Principal Investigator as someone making a significant contribution to a project. The Co-Investigator is an individual that the PI relies on to assume responsibilities above those of other personnel.
What is the definition of principal investigator in clinical research?
A Principal Investigator (PI) is the physician who leads the conduct of a clinical trial at a study site. Compliance with GCP provides assurance that the rights, safety and well-being of trial participants are protected, and that the results of the clinical trials are credible and accurate.
What is Pi in PHD?
From Wikipedia, the free encyclopedia. In Canada and the United States, the term principal investigator (PI) refers to the holder of an independent grant and the lead researcher for the grant project, usually in the sciences, such as a laboratory study or a clinical trial.
What is a pi%?
Succinctly, pi—which is written as the Greek letter for p, or π—is the ratio of the circumference of any circle to the diameter of that circle. In decimal form, the value of pi is approximately 3.14.
What is a PI in technology?
The Raspberry Pi is a low cost, credit-card sized computer that plugs into a computer monitor or TV, and uses a standard keyboard and mouse. We want to see the Raspberry Pi being used by kids all over the world to learn to program and understand how computers work.
What does PI stand for in biochemistry?
The isoelectric point (pI, pH(I), IEP), is the pH at which a molecule carries no net electrical charge or is electrically neutral in the statistical mean. The standard nomenclature to represent the isoelectric point is pH(I). However, pI is also used.
What is pi value of protein?
Protein Extraction and Precipitation The isoelectric point (pI) is the pH of a solution at which the net charge of a protein becomes zero. At solution pH that is above the pI, the surface of the protein is predominantly negatively charged, and therefore like-charged molecules will exhibit repulsive forces.
How do u calculate pi?
The circumference of a circle is found with the formula C= π*d = 2*π*r. Thus, pi equals a circle’s circumference divided by its diameter. Plug your numbers into a calculator: the result should be roughly 3.14. Repeat this process with several different circles, and then average the results.
Is Pi 3.14 or 180?

| 180° | π | 3.142 |
| 270° | 3π/2 | 4.712 |
Is Pi odd or even?
Pi is odd. Since pi is not an integer, so there is no question of it being Odd or Even. So Pi is neither Odd nor even because it is not an integer.
Are there any patterns in pi?
We have known since the 18th century that we will never be able to calculate all the digits of pi because it is an irrational number, one that continues forever without any repeating pattern. But, despite the endless string of unpredictable digits that make up pi, it’s not what we call a truly random number.
Is there a 666 in pi?
666 = 16 – 26 + 36. It is also equal to the sum of its digits plus the cubes of its digits: The sum of the first 144 (= (6+6)·(6+6)) digits of pi is 666.
Is there a zero in pi?
Yes. Pi has an infinite number of zeros. Pi=3.50. And that is the first zero.
Can you find your birthday in Pi?
March 14 is recognized across the math world as Pi Day, thanks to the resemblance of the date “3/14” to the first three digits of mathematics’ most famous constant. 3, or “1203” — beginning at the 60,873rd digit. …
Who first calculated pi?
Archimedes of Syracuse
Does the number pi end?
Pi is an irrational number. As such, it has no final digit. Furthermore, there is no pattern to its digits.
What are the first 1 million digits of pi?

What are the 31 trillion digits of pi?
Iwao calculated pi to 31 trillion digits (535,897), far outpacing the previous record of 24.6 trillion, set in 2016 by Peter Trueb.
Do numbers repeat in pi?
The digits of pi never repeat because it can be proven that π is an irrational number and irrational numbers don’t repeat forever. . That means that π is irrational, and that means that π never repeats.
