To investigate the likely range of the GST variations, authors have demonstrated three examples of the possible GST histories that progressively enlarge the amplitudes of the inferred GST change by a greater weighting given to the data. The most reliable range for the GST changes is restricted by...

Human activities which generate income are known as economic activities. Economic activities are broadly grouped into primary, secondary, tertiary activities. Higher services under tertiary activities are again classified into quaternary and quinary activities. Let us first understand the differences between ...
There are few known examples of the influence of climate on tufa formation during Quaternary interglacials in the European region influenced by Atlantic climate. Except for a few notes describing tufas in Portugal (e.g., Choffat,1895; Flyche,1907; Mendes,1974; Soares et al.,1997) or as p...
For examples, a careful selection of catalysts and reaction conditions is needed to inhibit the hydroformylation of the allylating reagent and the product, which also possess C–C double bonds. The presence of CO gas will almost definitely deactivate the Pd catalyst and make the whole reaction ...

This article has beenupdated Abstract Chiral bridged [2,2,1] bicyclic lactones are privileged structural units in pharmaceutics and bioactive nature products. However, the synthetic methods for these compounds are rare. Here we report an efficient method for enantioselective construction of bridged [...

Additionally, environmentally-sensitive grain size fractions extracted from closed-basin lake sediments are used to reflect local aeolian activity and dust storms. Examples include the flux of fractions 3 (15–65 μm) and 5 (>150 μm) at Xiari Nur (Xu et al., 2018); the 19–78 μm ...
These examples serve as testimony to the wide spectrum of applications possible for this class of compounds. All of them (or intermediates leading to them) can be prepared using the present invention . Without further elaboration, it is believed that one skilled in the art can, using the ...
