It's important to note sales in RMB and USD due to varying exchange rates.
Rb+- and Cs+-exchanged Beta zeolites (RbxNa1−xβ and CsxNa1−xβ) of varying exchange degrees (x = 0 1.00) were employed to catalyze the gas-phase dehydration of lactic acid (LA) for sustainable production of acrylic acid (AA) in a flow fixed-bed reactor at 360 °C, using an aqueous solution of LA (10 mol% or 35.7%) as the reaction feed at a weight hourly space velocity by LA of 2.1 h−1.
What's further disturbing is how widely the prices are varying across exchanges — there doesn't seem to be a stable consensus on where the price is.
This paper explores the hydrology of the extensive floodplains of Poyang Lake Chinaa) to highlight complex, hysteretic relationships in the inundation dynamics, which are controlled by the heterogeneity of the land surface and time-varying exchanges between the Lake, its catchment and the Yangtze River.
With an annual areal variation about six times as great as that for the Arctic ice pack, the Antarctic pack doubtless plays a far greater role in varying heat exchange between ocean and atmosphere and thus probably in altering global weather patterns.
The procedure involves giving the subject 100 tokens to allocate between the sooner and later time period, and then varying the exchange rate between tokens and money for sooner or later amounts.
Their subsequent albums saw the group straddling the boundaries between black, death, and thrash metal, with "impressive, tastefully rendered epics chock-full of superb riffs, Middle Eastern melodies, and vocal exchanges varying from a throaty midrange screech to chanting".
Those opting for the latter are used to the amount they get varying because of exchange rates.
The composition of the multi-shelled ZnS-CdS RDCs can be tuned by varying the cation-exchange reaction time, and the shell number can be adjusted by changing the size of ZIF-8 precursors.
Without going into a William Jennings Bryan gold standard history lesson, let's just say the idea that I can hold this thing, this little cloth rectangle of varying denomination, and exchange it for tangible goods and services is, at the very least, a system of belief.
