In the title compound, C27H22N2O4, the two indole ring systems are approximately perpendicular to each other, with a dihedral angle of 84.5 (5)° between their planes; the benzene ring is twisted with respect to the two indole ring systems at angles of 78.5 (5) and 86.5 (3)°. In the crystal, mol-ecules are linked by N-H⋯O hydrogen bonds, weak C-H⋯O and C-H⋯N hydrogen bonds, and C-H⋯π inter-actio...

Two-day-old male cowpea weevils, Callosobruchus maculatus, fly upwind to a point source of female sex pheromone at three wind speeds. All beetles initiating flight along the pheromone plume make contact with the pheromone source. Analysis of digitized flight tracks indicates that C. maculatus males respond similarly to moths tested at several wind speeds. Beetles’ mean net upwind speeds and spe...

The title compound, [Fe(2)(C(5)H(5))(2)(C(24)H(22)BP(2))(CO)(4)][FeCl(4)]·CHCl(3), is an oxidation product of CpFe(CO)(2)PPh(2)BH(3). One pair of phenyl rings attached to the two different P atoms are almost parallel, as are the other pair [dihedral angles = 8.7 (5) and 8.9 (5)°]. The planes of the two cyclo-penta-dienyl rings are inclined by 26.8 (7)° with respect to each other. The carbonyl g...

Background: We used a MapCHECK software-based dimensional dose distribution comparison method capable of evaluating point-to-point geometrical dose differences in volume to determine whether doses obtained from an enhanced computed tomography (CT)-based treatment plan, which better defines the target regions and organs at risk, differs from doses obtained from plain CT and then evaluated the fe...

To achieve complete extended right hepatectomy or trisectionectomy for a bismuth type IV hilar bile duct carcinoma, we propose the application of Belghiti's liver hanging maneuver (LHM) using a small nasogastric tube. This small nasogastric tube was placed in the cut plane: the top of the tube was placed between the hepatic veins. The tube was placed along the border between the left lateral se...

In the title compound, C18H16N4O, the planes of the phenyl rings are approximately perpendicular to each other [dihedral angle = 78.07 (8)°] and form dihedral angles of 56.43 (8) and 24.59 (8)° with the pyrazole ring. In the crystal, mol-ecules are linked by N-H⋯O hydrogen bonds to form one-dimensional chains parallel to the [010] direction.

In the title compound, C(42)H(30)N(4), the conformations of the three wings of the mol-ecule are not similar to each other as the torsion angles between the planes of the benzene rings are significantly different. In addition to van der Waals inter-actions, the crystal structure is stabilized only by intra-molecular C-H⋯N hydrogen bonds.
