2022-1-31 · This can work either way: the protective mass (likely ice) will be packed in the "top" of the cone and the ship accelerated with the wide end forward. This will have the dual purpose of putting as much protective mass as possible forward and using the mass as a form of "wake shield", so the rest of the cone travels in a much harder vacuum than even interstellar space.
How to Measure PCV Using Microhaematocrit Centrifuge
2020-12-13 · The PCV value is read from the scale of a microhaematocrit column by the height of the total column of blood. Note: Due to trapped plasma, PCV values using a centrifugation technique are 1-3% higher than those obtained when using an electronic cell analyzer which computers the value from the MCV and red cell count (PCV=MCV x RBC). Specimen: To
