The chemical weathering of carbonate rocks is a complex terrestrial process that is controlled by numerous natural and anthropogenic drivers5,6,7,8,9. To summarize and simplify the mixed impacts of all drivers, a generic equation for the carbon-sink flux produced by carbonate weathering can be ...
Thus, instead of being hypermetabolic, as commonly assumed, solid tumours generally produce ATP at a slower than normal rate. In mouse pancreatic cancer, this is accommodated by the downregulation of protein synthesis, one of this tissue’s major energy costs. We propose that, as solid tumours...
This invention is directed to a flux and the process of using it in the soft soldering of metals, such as tin plate, galvanized iron, copper, brass, etc. I have found that phosphates which decom6 pose at or below the temperatures used in soft soldering constitute excellent fluxes. The tem...
摘要: The invention described herein may be manufactured and used by or for the Government for governmental purposes without the payment to us of any royalty thereon. This invention related to soldering fluxes. More particularly the present invention relates to soldering fluxes of the so-called......

The sample is used as the cathode and the anode is made of the deposit...
WY-14,643 is a potent and widely used PPARα activator. The compound was previously shown to electively increase the expression of genes involved in cardiac FA metabolism in both nRCM10 and aRCM11,12. In nRCM it was shown to enhance FAO rate by 1.5-fold, both when measured as 14CO2 pr...
17). Interpretation of relative abundances across communities is a common exercise in contemporary studies of microbial ecology. Averaged across all ecosystems, 36 bacterial genera contributed to >50% of sequenced 16S amplicons. Of genera common to all soils, only six were necessary to obtain >50%...

A flux consisting of 20-50 wt.% lithium fluoride, 30-60 wt.% sodium fluoride, and 10-40 wt.% calcium fluoride is used for welding aluminium under an electrically conducting liquid. The high viscosity, and the high interfacial tension between the flux and molten metal give superior welds, ...
