the proposed method, the profit maximization problem is transformed into a minimization problem that can be solved by a traditional hydro-thermal unit commitment program after implementing a few modifications. The paper describes t he modifications introduced in a unit commitment program based on the Lagrangian relaxation approach and on a disaggregated Bundle method for the solution of the dua...

In the title compound, C14H13NO3, the dihedral angles between the central pyrrolidine ring and the pendant tetra-hydro-furan and phenyl rings are 5.34 (18) and 58.99 (17)°, respectively. The tetra-hydro-furan ring is almost planar (r.m.s. deviation = 0.008 Å). In the crystal, mol-ecules are linked by C-H⋯O inter-actions, generating a three-dimensional network.

The title compound, 6,7-de-hydro-royleanone, C20H26O3 [systematic name: (4bS)-3-hy-droxy-2-isopropyl-4b,8,8-trimethyl-4b,5,6,7,8,8a-hexa-hydro-phenanthrene-1,4-dione] was isolated from Taxodium distichum (L.) Rich. The compound crystallizes in the space group P21. The crystal structure features two O-H⋯O hydrogen bonds, forming chains along the [010] direction.

In the title mol-ecule, C11H10ClFO2, the benzene ring, the F atom and the O atom of the di-hydro-pyran ring are essentially coplanar, with an r.m.s. deviation of 0.007 Å. The di-hydro-pyran ring is in a half-chair conformation. In the crystal, mol-ecules are linked by pairs of weak C-H⋯π hydrogen bonds, forming inversion dimers.

The structure of the racemic title compound, C(10)H(15)NO(4), consists of a tricyclic skeleton comprising a six-membered piperidine ring and five-membered isoxazolidine and tetra-hydro-furan rings. The piperidine ring adopts a distorted chair conformation, while the isoxazolidine and tetra-hydro-furan rings have envelope conformations.

In the title compound, C(19)H(22)N(4)O(2), the tetra-hydro-pyrimidine ring adopts an envelope conformation (with the N atom connected to the benzyl group representing the flap). This benzyl group occupies a quasi-axial position. The two benzyl groups lie over the tetra-hydro-pyridimidine ring. The amino group is a hydrogen-bond donor to the nitro group.

The innovative design and synthesis of nanofiber based hydro-philic/phobic membranes with a thin hydro-phobic nanofiber layer on the top and a thin hydrophilic nanofiber layer on the bottom of the conventional casted micro-porous layer which opens up a solution for membrane pore wetting and improves the pure water flux in membrane distillation.

The title limonoid 14-de-oxyxyloccensin K, C(27)H(34)O(7), isolated from Chisocheton ceramicus (Meliaceae), features an oxygen linkage between carbon-3 and carbon-8 along with a tetra-hydro-furyl sub-unit. The six-membered rings adopt chair configurations and the tetra-hydro-furyl sub-unit has an envelope shape.

In the title compound, C14H14O4, the dihedral angle between the hydro-furan and benzene rings is 88.41 (15)°. The hydro-pyran ring adopts an envelope conformation, with the O-bound methyl-ene C atom as the flap. In the crystal, weak aromatic π-π stacking is observed [centroid-centroid separation = 3.848 (2) Å].
