Determining the physical conditions of extremely young Class 0 circumbinary disk around VLA1623A
We present detailed analysis of high-resolution C18O (2-1), SO (88-77), CO
(3-2) and DCO+ (3-2) data obtained by the Atacama Large
Millimeter/sub-millimeter Array (ALMA) towards a Class 0 Keplerian circumbinary
disk around VLA1623A, which represents one of the most complete analysis
towards a Class 0 source. From the dendrogram analysis, we identified several
accretion flows feeding the circumbinary disk in a highly anisotropic manner.
Stream-like SO emission around the circumbinary disk reveals the complicated
shocks caused by the interactions between the disk, accretion flows and
outflows. A wall-like structure is discovered south of VLA1623B. The discovery
of two outflow cavity walls at the same position traveling at different
velocities suggests the two outflows from both VLA1623A and VLA1623B overlays
on top of each other in the plane of sky. Our detailed flat and flared disk
modeling shows that Cycle 2 C18O J = 2-1 data is inconsistent with the combined
binary mass of 0.2 Msun as suggested by early Cycle 0 studies. The combined
binary mass for VLA1623A should be modified to 0.3 ~ 0.5 Msun.Comment: 26 pages, 20 figures, accepted by ApJ 2020.2.2

3,3′-Di-tert-butyl-2′-hydroxy-5,5′,6,6′-tetramethylbiphenyl-2-yl benzenesulfonate
In the title compound, C30H38O4S, the hydroxyl group bonded to one phenyl ring and an O atom of the benzenesulfonate group attached to the other phenyl ring of the biphenyl backbone of the structure are involved in an intramolecular O—H⋯O hydrogen bond. The dihedral angle between the planes of the two aromatic rings of the biphenyl unit is 70.4 (2)°
(E)-N-[2-(Benzyliminomethyl)phenyl]-2,6-diisopropylaniline
The molecular conformation of the title compound, C26H30N2, is reinforced by an intramolecular N—H⋯N hydrogen bond, resulting in an almost planar [mean deviation of 0.023 (2) Å] S(6) ring. The dihedral angles between the central benzene ring and the terminal unsubstituted and substituted aromatic rings are 64.45 (9) and 89.40 (8)°, respectively
Bis(μ-9-anthracenemethanolato)bis[dimethylaluminium(III)]
The title complex, [Al2(CH3)4(C15H11O)2], is dimeric bridged through the O atoms of the 9-anthracenemethanolate anions. Each Al atom is tetracoordinated by two bridging O atoms from two different 9-anthracenemethanolate ligands and by two C atoms from two methyl groups, forming a distorted tetrahedral environment. The average Al—O bond distance in the Al2O2 core is 1.845 Å
Predictors of intra-abdominal coagulopathic hemorrhage after living donor liver transplantation
AbstractBackgroundResults of preoperative conventional coagulation assays are a poor predictor of hemorrhage after liver transplantation. In this study, we evaluated the factors that are predictive of intra-abdominal coagulopathic hemorrhage after living donor liver transplantation surgery.MethodsDuring the period from January 2009 to December 2012, 118 adults underwent living donor liver transplantation (LDLT) in our institution. Of those patients, 18 (15.3%) developed intra-abdominal coagulopathic hemorrhage (n = 7) or hemorrhage due to non-coagulopathic causes (n = 11) that required emergency medical, radiological, or surgical intervention within the first month after LDLT. Possible predictors of postoperative coagulopathic hemorrhage included donor-related factors, age, body mass index, MELD score, INR value, intra-operative blood transfusion, graft/recipient weight ratio, anhepatic phase, cold ischemia time, operative time, APACHE II score, onset of re-bleeding, and hemoglobin levels during rebleeding episodes.ResultsThere were no differences in any of the variables between the two groups (coagulopathic and noncoagulopathic hemorrhage) except for cold ischemia time. We found that cold ischemia time was significantly longer in patients with postoperative coagulopathic hemorrhage (160.50 ± 45.02 min) than in patients with hemorrhage due to non-coagulopathic causes (113.55 ± 29.31 min; P = 0.027).ConclusionProlonged cold ischemia time is associated with postoperative intra-abdominal coagulopathic hemorrhage in patients after LDLT. It is, therefore, necessary to shorten the cold ischemia time in order to reduce the risk of postoperative intra-abdominal hemorrhage due to coagulopathic causes
2-(2H-Benzotriazol-2-yl)-6-[(diethylamino)methyl]-4-methylphenol
In the title compound, C18H22N4O, the dihedral angle between the planes of the benzotriazol unit and the phenyl ring of the phenoxy group is 6.4 (2)°. There is an intramolecular O—H⋯N hydrogen bond between the phenol and benzotriazol groups
Bis[2-(2H-benzotriazol-2-yl)-4-methylphenolato]palladium(II)
In the title complex, [Pd(C13H10N3O)2], the PdII atom is tetracoordinated by two N atoms and two O atoms from two bidentate 2-(2H-benzotriazol-2-yl)-4-methylphenolate ligands, forming a square-planar environment. The asymmetric unit contains one half molecule in which the Pd atom lies on a centre of symmetry
(E)-N-{2-[1-(Benzylimino)ethyl]phenyl}benzamide
In the title compound, C22H20N2O, the molecular conformation is supported by an intramolecular N—H⋯N hydrogen bond, resulting in an almost planar [mean deviation = 0.048 (2) Å] S(6) ring. The dihedral angles between the central benzene ring and the imine- and amide-substituted aromatic rings are 76.6 (2) and 11.7 (2)°, respectively
