Fine roots ( 1 mm diameter) are critical in plant water and nutrient absorption, and it is important to understand how rising atmospheric CO2 will affect them as part of terrestrial ecosystem responses to global change. This study’s objective was to determine the effects of elevated CO2 on production, mortality, and standing crops of fine root length over 2 years in a free-air CO2 enrichment (F...
co2 injection is an effective technique for improved oil recovery in light oil reservoirs, especially for water flooding abandoned reservoirs. in this study, the lower part of es1 reservoirs in pucheng oilfield was introduced as the target reservoir. by studying the minimum miscible pressure in co2 flooding, the reservoir could achieve miscible flooding. long core displacement experiments prove...
This article presents a numerical modeling application using the code TOUGHREACT of a leakage scenario occurring during a CO2 geological storage performed in the Jurassic Dogger formation in the Paris Basin. This geological formation has been intensively used for geothermal purposes and is now under consideration as a site for the French national program of reducing greenhouse gas emissions and...
The evidence for abundant liquid water on early Mars despite 3 the faint young Sun is a long-standing problem in planetary research. Here 4 we present new ab initio spectroscopic and line-by-line climate calculations 5 of the warming potential of reduced atmospheres on early Mars. We show 6 that the strength of both CO2-H2 and CO2-CH4 collision-induced absorp7 tion (CIA) has previously been sig...
Monitoring hypovolemia is an everyday challenge in critical care, with no consensus on the best indicator or what is the clinically relevant level of hypovolemia. The aim of this experiment was to determine how central venous oxygen saturation (ScvO2) and central venous-to-arterial carbon dioxide difference (CO2 gap) reflect hypovolemia-caused changes in the balance of oxygen delivery and consu...
UNLABELLED BACKGROUND Unmanaged or old-growth forests are of paramount importance for carbon sequestration and thus for the mitigation of climate change among further implications, e.g. biodiversity aspects. Still, the importance of those forests for climate change mitigation compared to managed forests is under controversial debate. We evaluate the adequacy of referring to CO2 flux measurem...
Reaction of bis-(pyridin-3-ylmeth-yl)sulfane (L) with cobalt(II) chloride in methanol led to the formation of the title coordination polymer, [CoCl2(C12H12N2S)(CH3OH)2] n , in which the CoII cation lies on a crystallographic inversion centre and the S atom of the L ligand lies on a twofold rotation axis. Each CoII ion is coordinated by two pyridine N atoms from two bridging L ligands, two O ato...
The synthesis and the structure of the new potentially heptadentate ligand 1,3-bis-(3-oxo-3-(2-hydroxyphenyl)-propionyl)-2-methoxybenzene (H5L) is described. The reaction in pyridine or DMF of this ligand with various M(AcO)2 salts (M = NiII, CoII, MnII) leads to very different products depending on the metal. Thus, the dinuclear complexes [M2(H3L)2(py)4] (M = NiII, 1; CoII, 2) or the linear zi...
In the title compound, [Co(C11H12NO6P)(C6H5N3)2]·C6H5N3, the 2,2'-[N-(phenyl-phospho-rylmethyl-κO)aza-nedi-yl]di-acetate dianion N,O,O',O''-chelates the CoII cation and two 1H-benzo[d][1,2,3]triazole mol-ecules coordinate to the CoII cation to complete the slightly distorted octa-hedral coordination. In the crystal, classical O-H⋯O, N-H⋯O hydrogen bonds and weak C-H⋯N hydrogen bonds link the mo...
