2. Half sphere exposure - Wikipedia

   en.wikipedia.org/wiki/Half_sphere_exposure

   Half Sphere exposure (HSE) is a protein solvent exposure measure that was first introduced by Hamelryck (2005). [1] Like all solvent exposure measures it measures how buried amino acid residues are in a protein. It is found by counting the number of amino acid neighbors within two half spheres of chosen radius around the amino acid.

   In the case of metals that are significantly heavier than the casting sand, such as iron or lead, the casting flask is often covered with a heavy plate to prevent a problem known as floating the mold. Floating the mold occurs when the pressure of the metal pushes the sand above the mold cavity out of shape, causing the casting to fail.

   Some volume-based recipes, therefore, attempt to improve the reproducibility by including additional instructions for measuring the correct amount of an ingredient. For example, a recipe might call for "1 cup brown sugar, firmly packed", or "2 heaping cups flour". A few of the more common special measuring methods: Firmly packed

7. Hoberman sphere - Wikipedia

   en.wikipedia.org/wiki/Hoberman_sphere

   A Hoberman sphere is a kinetic structure patented by Chuck Hoberman that resembles a geodesic dome, but is capable of folding down to a fraction of its normal size by the scissor-like action of its joints. Colorful plastic versions have become popular as children's toys: several toy sizes exist, with the original design capable of expanding ...
