One of the basic concepts of set theoretic geology is the mantle of a model of set theory V: it is the intersection of all grounds of V, that is, of all inner models M of V such that V is a set-forcing extension of M . The main theme of the present paper is to identify situations in which the mantle turns out to be a fine structural extender model. The first main result is that this is the case...

when the a particle is initially in the state i. The Sij's are determined from the relative intensity of the lines emitted in transition from that state. Take the particular case where S12 = S02 = 1/2 and (12 = #o2 = (01 1-7 13= 1/200 then P1/P2 = 4.3. This ratio is nearly the same as that of the internal conversion coefficient of y rays from RaC. There the values of this coefficient can be div...

Many organizations interested in renewable, domestic energy have switched from petroleum diesel to biodiesel blends for use in transportation and heavy-duty equipment. Although considerable evidence exists on the negative health effects of petroleum diesel exhaust exposures in occupational settings, there has been little research examining biodiesel exposures. Working collaboratively with a loc...
