Black carbon (BC) plays an important role in the climate system because of its strong warming effect, yet the magnitude of this effect is highly uncertain owing to the complex mixing state of aerosols. Here we build a unified theoretical framework to describe BC’s mixing states, linking dynam...
For the three-dimensional cubical box, the ground state is given by n1 = n2 = n3 = 1. Why is it not possible to have one ni = 1 and the other two equal to zero? Go through the arithmetic to verify that diamond becomes more...
in the housing. The screw sections each have an outside diameter to inside diameter (OD-ID) ratio of “greater than or equal to” 1.55. A drive mechanism rotates screw shafts are rotated in the same direction and in the same sense at rotational speeds of “at least” 800 rpm and at ...
which bleaches and fixes the image in a single step. The bleaching bath is a water solution having a pH equal to 5.60 and containing an oxidizing agent, normally a complex salt of an alkali metal or of ammonium and of trivalent iron with an organic acid, e. g. EDTA.Fe.NH4, wherein...
