Along the left side of the table, I labeled the rows alphabetically. (**This is optional but helps younger kids who are uncomfortable pronouncing the names of the elements yet.) They already have row numbers along the top. Laminating makes it re-usable! I used two file folders and hooked ...
A comparison of the tetrahedron shells and the table of elements shows, that one tetrahedron shell corresponds to 4 periods of the 2D table."Jess Tauber adds:"The spheres here also aren't labeled, but I explain how they get labeled in the text accompanying the pic. Each such period (...
It is interesting to note that the maximum yield is not located along the centerline but in regions offset towards the top and bottom. In the central region within 8 mm from the centerline labeled “A”, the exposure dose is approximately 52 mJ/cm2, slightly above the nominal exposure...
Fluorescent nanoscopy, on the other hand, requires costly equipment and special analysis routines, which remain inaccessible to most research groups. This report aims to resolve this issue by using protein-retention expansion microscopy (pro-ExM) to reveal the MPS of axons. ExM uses reagents and ...

Over the last century, fire exclusion has caused dramatic structural and compositional changes to southern New England forests, highlighting the need to reintroduce fires into the historically pyrogenic landscape to study the response. We investigated th
