It appeared to be of fixed shape, a cylindroid almost ten kilometers in length and two in diameter, majestically rotating on its long axis, mother-of-pearl iridescent.
In a hold, among cases of supplies for the research team on Gwinsai, he was surprised to recognize a lean cylindroid, one hundred twenty centimeters long.
Under-gravitationally speaking, above-the ship's skin, there was a five-meter space running almost the whole length of the cylindroid.
She was a big cylindroid, two hundred and forty meters long from the blunt nose to the gravitic focusing cones at the stern, forty meters in diameter.

The larger calculi, sometimes weighing 12 to 24 ounces, are molded in the pelvis of the kidney into a cylindroid mass, with irregular rounded swellings at intervals.
In mathematical modeling and experiments testing the efficacy of several conditions: drug or dye with no particles; particles coated with fluorescein dye, positive or negative charge; and particles coated with anti-cancer drug doxorubicin, positive or negative charge, the UMass Amherst researchers show that gold nanoparticles move and localize differently in the 3-D cylindroid tumor tissue, depending on whether the nanoparticles are positively or negatively charged.
But by experimenting with different payloads carried on the gold nanoparticles in the new tumor cylindroid device,
