Rare particles are very small spheres (Fig. 3b), up to 8 μm in size, perfectly round and smooth.
Needless to say practically, very small quantities of Spheres (x<6) present a particular dilemma in attempting to form a lemniscate with so few.
In all five formulations (from Fig. 2A to 2E), the monolayer structure spheres were predominant, and the independent bilayer structure spheres were a very small minority, replaced by the double-sphere structure.
A very small number of GFP+ve spheres was observed when the entire GFP-negative fraction was plated from either Sox2 EGFP/+ or Sox9 iresGFP/iresGFP mice (0.0035%, n = 2).
Combining this with the high noise, which is characteristic of 90Y PET images, it is apparent from Fig. 2 that very small regions of high uptake (i.e., the smallest sphere) are difficult, if not impossible, to identify.
"They make it into a tiny sphere that actually casts a very small shadow," Dr. Johnsen said.
It's true that no one person can create a feminist utopia overnight, but if we each took a few simple actions to challenge sexism in our own small sphere, together we could make a very big difference indeed.
It shows how insidiously the tentacles of religious zeal invade every sphere of national life, despite the very small number of religious practitioners in this most secular of nations.
Within the IT sphere, women executives still make up a very small per centage and representation of the global Fortune 500 companies, at about 13%.
Each sphere has a black half, which carries a very small static electricity charge, and a white half, which is electrically neutral.
