Subject : engineering
Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. Where are the tissue factors found when they're inactivated






2. ____ is the process by which cells involved in inflammation internalize and destroy foreign material.






3. Thrombin activates several upstream factors.






4. Cells that proliferate slowly over time (aka liver)






5. Are polymer additives used to lower glass transition temperature temperature.

7. The process of calibration establishes a quantitative relationship between ____ __ ___ _____ and the direct output of the intstrument (for example time/volume in GPC).






8. A condensation polymerization results with an ester bond between two reactants and this comes off as a result

24. The fatigue limit is the ___ below which the material can withstand an infinite number of cycles without failure.






25. Condition in which patients can literally bleed to death.






26. Type of fiber drawing that controls details of a polymer by etching on a microscopic level; thus - controlling mechanical properties as well






27. A molecular pathway in which the product of each reaction catalyzes the subsequent reaction.






28. High conductivity - isotropic - crystalline
