In the crystal structure of a semi-synthetic opioid drug buprenorphine, C29H41NO4 {systematic name: (2S)-2-[(5R,6R,7R,14S)-9α-cyclo-propyl-methyl-3-hy-droxy-6-meth-oxy-4,5-ep-oxy-6,14-ethano-morphinan-7-yl]-3,3-di-methyl-butan-2-ol}, the cyclo-propyl-methyl group is disordered over two sites with an occupancy factor of 0.611 (3) for the major component. One of the hy-droxy groups is involved in...

The Goal for development of Extraction HY-1B Level 1B (L1B) Product Image Data Procedure is to enhance the convenience of retrieving product data for users. The images extracted from L1B data are used as a quick look images for Product Archive and Distribution System of HY-1B (PADS) [1] and can be presented with a map while consumers search for data via Internet. And the procedure is integrated...

Data regularization is cast as a least-squares inversion problem. The model space is a five-dimensional (t,cmpx, cmpy, hx, hy) hypercube. The regularization minimizes the difference between various (t, cmpx, cmpy) cubes by applying a filter that acts in (hx,hy) plane. Azimuth Move-out is used transform the cubes to the same ( hx,hy) before applying the filter. The methodology is made efficient ...

High-precision Hylleraas-configuration-interaction Hy-CI method variational calculations are reported for the 2 S ground state of neutral lithium. The nonrelativistic energy is calculated to be −7.478 060 323 451 9 hartree, demonstrating that the Hy-CI technique is capable of sub-nanohartree accuracy for three-electron systems. A Hylleraas expansion without linked products of odd powers of rij ...

The title compound, C26H21O3P, was obtained as by-product due to the hydrolysis of the desired tosyl-ated compound. The dihedral angles between the three aromatic rings attached to the P atom lie in the range 78.1 (1)-87.6 (1)°. The hy-droxy-methyl group is disordered between two conformations in a 0.719 (9):0.281 (9) ratio. The hy-droxy H atom is not involved in inter-molecular inter-actions, ...

Mol-ecules of the title compound, C7H10N2O4, systematic name 5-hy-droxy-5-propyl-pyrimidine-2,4,6(1H,3H,5H)-trione, form a hydrogen-bonded framework which is based on three independent hydrogen bonds, N-H⋯O(carbon-yl), N-H⋯O(hy-droxy) and O-H⋯O(carbon-yl). This framework has the topology of the 5-connected nov net. Each mol-ecule is linked to five other mol-ecules via six hydrogen bonds, and th...
