The theme of its second cycle, Transformation, takes up the personal, political, cultural, and ecological value and direction of change.
Cells used for assay of proliferation, cell cycle, transformation and tumorigenicity were prepared by viral infection and continuously treated with 1 μM of B[alpha]P for 4 weeks (10 passages), then the cells were harvested and kept at -80°C until use.
We propose that complex multi-cycle transformations of reduced sulfur species including disproportionation reactions could be responsible for negative Δ33S difference between sulfide and sulfate in these pools and springs.
What remains recognisable is the pattern of the circle, a shape expressive of constantly moving cycles, transformation, and the female body.

From 7 30 to around 11 on any given night, a cycle of transformations takes place in the air, trees, sky and light.
However, unlike the TCA cycle, no transformations beyond an aldol addition and an alcohol oxidation are required to enable the decarboxylation chemistry, thus greatly simplifying the overall pathway from nine steps in the TCA cycle to four steps in each abiotic protometabolic cycle.
After the first cycle of transformations, the penetration depth of cobalt atoms was already 3.5 microns (Figure 1, curve 1).
Calculations have shown (Figure 3) that after the first cycle of transformations the diffusion coefficient of cobalt D at a temperature of 250°C was equal to 2.36 × 10−13 cm2/s.
The present-day lushness of the river habitat belies a dramatic cycle of transformations that began in the 1950s when the once-wild river, historically known for overflowing its banks and causing floods, was tamed.
