The internal structure of placer gold depends on its residence time under exogenetic conditions. Two types of placer gold are distinguished in the middle Lena River basin by typomorphic features. Gold of distal transfer (type I) is characterized by recrystallized structure, deformation lines, and ...

In the case of C-14, the transmutation to N-14 will totally destroy the molecule since the two elements have different valency, outer electron structure, and reactivity. Owing to the long half-life of C-14, experiments on its genetic effects have been difficult to carry out. Nevertheless, ...
A gold decoration technique has been applied to the electron microscopic study of the internal structure of a polyethylene fiber. The optical transform technique has elucidated the locations of various types of crystals which were regularly spaced and contributed to the appearance of meridional ...
