Feb 04, 2020 · Cyclic AMP (cAMP) is involved in many biological processes but little is known regarding its role in shaping immunity. Here we show that cAMP-PKA-CREB signaling (a pattern recognition receptor [PRR]-independent mechanism) regulates conventional type-2 Dendritic Cells (cDC2s) in mice and reprograms their Th17-inducing properties via repression of IRF4 and KLF4, transcription factors
MARINE CHEMISTRY Radioactivity in the Marine For the total dissolved inorganic carbon, 3 X10"4 moles/ liter result from the combustion of organic carbon, and 1 X10-" moles/liter from the fallout of CaCO3. The carbo- nate alkalinity, nitrogen, phosphorus, and carbon data are internally consistent, and show that for each mole of CaCO3 dissolving in the deep sea, organic material containing 3 moles of organic carbon must be oxidized.
Mechanism and technological opportunity of plasma Nov 01, 2020 · An elemental analysis of a solution of ammonium sulphate after PEP of stainless steels shows that the Ni concentration is 209 mg/l, as well as 70 mg/l of Cr, 40 mg/l of Ca, 31 mg/l of Si, 26 mg/l of Mg, and only 13 mg/l of Fe . The authors note that almost all iron ions are related to oxide and precipitate in an acidic medium (pH 2.2), while
In wet CO 2 environments, one of the main limitations of Martensitic Stainless Steels (either as API L80-13CR or any enhanced version like SM13CRS) are:. Corrosion Resistance in High Temperature environments; SSC (Sulfide Stress Cracking) resistance in presence of H 2 S; SCC (Stress Corrosion Cracking) resistance in combined presence of H 2 S and Chlorides.; In low content H 2 S
Nippon Steel Tubular ProductsSM2550 is an Austenitic Ni base material required for critical well conditions combining high concentrations of CO 2, H 2 S and Chlorides that was launched in the mid-80s by Nippon Steel for Tubing & Liner applications in severe environments. It benefits from Nippon Steels unrivaled know-how in manufacturing CRA (Corrosion Resistance Alloys) materials and best-in-class quality control.
Relativistic Heavy-Neighbor-Atom Effects on NMR Shifts Chemical shifts present crucial information about an NMR spectrum. They show the influence of the chemical environment on the nuclei being probed. Relativistic effects caused by the presence of an atom of a heavy element in a compound can appreciably, even drastically, alter the NMR shifts of the nearby nuclei. A fundamental understanding of such relativistic effects on NMR shifts is important
Dec 10, 2020 · Sanicro ® 41, commonly known as Alloy 825, is an austenitic corrosion resistant Ni-Fe-Cr alloy. It is characterized by:Excellent resistance to stress corrosion cracking in chloride and sour (H 2 S/Cl-) environments; Excellent resistance to attack by acidic media such as sulfuric and phosphoric acid
