The radiotracer technique has been applied to find the transference number of anion/cation constituents of iodine-alcohols
“inner chargetransfer complexes” and it is deduced that the anions are the main charge carriers.
The analyses of the ashes of coals given in Part I were carried out and the percent transferences of the elements into ash
were determined. In addition, the dependence of the transferences of arsenic and selenium, known as very strong toxicants,
on the particle size burnt and on the burning temperature were investigated.
In this paper, we discuss some geometric properties of three types of Riemannian submersions whose total space is an almost
contact metric manifold with 3-structure. The study is focused on the transference of structures.
The concentration of 20 trace elements in nine different brands of Turkish cigarette tobacco and in a brand of pipe tobacco
and in tobacco ash has been determined by instrumental neutron activation analysis. The percent transference of elements into
smoke has been estimated from the amounts remaining in the ash.

The concentration of certain toxic and essential elements in various brands of tea consumed locally were determined using
instrumental neutron activation analysis. Transference of these elements into the drinkable portion was studied by brewing
and boiling tea leaves for two minutes and the approximate intake was calculated from this data. The toxic effects of Hg,
Se, As, Br and Sb are briefly discussed.
The concentration of 15 elements in various brands of cigarette tobacco and cigarette wrapping paper were determined using
instrumental neutron activation analysis. The paper of some of the brands contains higher concentrations of toxic elements
than the tobacco. The cigarette filter and the ash were also analyzed to determine the adsorption of toxic elements on the
filter and their transference in smoke. The toxic effects of some of the elements have been briefly discussed.

Instrumental neutron activation analysis has been employed to determine 14 trace elements in two brands of Iranian and foreign
tea. The elements are: Br, La, Ba, K, Mn, Cl, Cr, Cs, Rb, Fe, Co, Zn, Sc and Au. The transference ratio of the elements into
solution, when tea is leached by percolation, is also reported. It was found that some elements are totally transferred into
solution and some are partially retained by the leaves.
