The main objective of the study was an attempt to obtain a
general explanation for the geographical pattern of agricultural income.
This was undertaken in the belief that certain possible determinants
of agricultural income, specifically those related to natural
resource characteristics, have not been satisfactorily considered in
investigations up to...
The physico-chemical reactions of ammonia in soils and clays have many practical and theoretical implications. On the one hand, large quantities of anhydrous ammonia are used annually in agriculture for fertilizer; the dry gas is applied directly to the soil by simply injecting it below the ground surface. On the...
Time-resolved fluorescence spectroscopy was used to monitor the effects of
varying ionic strength on nucleosome core particle structure. Two main methods were
used in these studies. First, the fluorescence anisotropy decay of bound ethidium was
measured and was shown to reflect the rotational tumbling of the core particle through
solution,...
