“…In this analysis, a natural process is split into a family of curves, each describing this process in a definite frequency range. The results of such an analysis for variations in global temperatures and solar intensity for the period of 1850-2007 show cyclic behaviour of the process components, with 11-, 25-, 100-, and 165-year periods (comparison of d 3 , d 4 , d 6 and d 7 components is displayed in Of the mentioned, the 11-year cycle (d 3 ) is well known. The 25-year cycle (d 4 ) is close to the (also known) Bruckner cycle.…”

The view of existing tendencies in climate changes proposed by the authors is based on the available facts. Earlier, cyclic behaviour of the world's river flows was discovered, which was found to correlate with the cycles of solar intensity. Similar correlation was revealed by the authors for global temperature anomalies. Based on the wavelet analysis it became possible to notice a phase inversion in these processes, which, in the authors' opinion, could be associated with re-magnetisation of the Sun. This, for example, explains the hitherto inexplicable interruption in the temperature rise during the 1950-70-ies. The authors stress that the processes of global climate changes are of ambiguous character, being consisted of the natural and the anthropogenic components.

The kinetics and mechanism of decomposition of NTA complexes of FeIII, FeII, CoII, NiII, and CuII under hydrothermal conditions (425–573 K) have been examined. The relative rates at 573 K are CoIINTA− < NTA3−[Formula: see text] < NiIINTA− < FeIIINTA0 < H3NTA0 < CuIINTA− < H4NTA+. Aqueous CoIINTA− and FeIINTA−, like NTA3−, decomposed at 573 K by decarboxylation, precipitating Co(OH)2 and Fe3O4 respectively; NiIINTA− precipitated Ni(OH)2 initially but subsequently Ni metal. At 530 K, FeIIINTA0 solutions precipitated FeII3(NTA)2•H2O, but at higher temperatures Fe3O4 formed, the NTA ligand being reduced to HCHO and iminodiacetate (IDA) rather than decarboxylated. Similarly, CuIINTA−gave IDA and HCHO at temperatures as low as 425 K, forming first CuI (which precipitated as CuCl in the presence of Cl−) and then metallic Cu. The applicability of NTA to corrosion control in boilers and to 60Co removal from water-cooled nuclear reactors is briefly considered. The half-life of FeIIINTA in the hydrosphere is estimated at 80 years (cf. 8 × 106 years for free NTA), in the absence of photolysis or biodégradation.

Perineal talc use and ovarian cancer risk

A number of observational studies (largely case-control) conducted over the last two decades suggest an association between use of talc powders on the female perineum and increased risk of ovarian cancer. A subset of these reports shows a roughly 30-60% increased risk of ovarian cancer associated with perineal talc exposure. A number of researchers partly base their conclusions of an association on the '…chemical relationship between talc and asbestos', the latter substance being a known human carcinogen. Although separating causal from noncausal explanations for an observed statistical association is a difficult process, there currently exist commonly accepted guidelines by which such inferences can be made. These scientific approaches include consideration of the strength of the association, the consistency of the finding across studies, and existence of a biological explanation of the observed phenomenon, among others. When applied to the context of a proposed talc/ovarian cancer association, we conclude that the weak statistical associations observed in a number of epidemiological studies do not support a causal association.
