Bi-objective optimization of a multi-product multi-period three-echelon supply-chain-network problem is aimed in this paper. The network consists of manufacturing plants, distribution centers (DCs), and customer nodes. To bring the problem closer to reality, the majority of the parameters in this network including fixed and variable costs, customer demand, available production time, set-up and ...

The reaction of 2-(2-oxo-2,3-di-hydro-1,3-benzo-thia-zol-3-yl)acetic acid (NBTA) and tri-ethano-lamine (TEA) with Co(NO3)2 results in the formation of the title complex, [Co(C6H15NO3)2](C9H6NO3S)2, which is formed as a result of the association of bis-(tri-ethano-lamine)-cobalt(II) and 2-(2-oxo-2,3-di-hydro-1,3-benzo-thia-zol-3-yl)acetate units. It crystallizes in the monoclinic centrosymmetric...

Reaction of BI3 with carbodi-phospho-rane, C(PPh3)2, gives a mixture of the dicationic compounds, methyl-enebis(tri-phenyl-phospho-nium) diiodide di-chloro-methane disolvate, C37H32P22+·2I-·2CH2Cl2 or [Ph3PCH2PPh3]I2·2CH2Cl2 (I), methyl-enebis(tri-phenyl-phospho-nium) bis-(tetra-iodo-borate), C37H32P22+·2BI4- or [Ph3PCH2PPh3](BI4)2 (II). Solvents are the source of the protons at the ylidic C at...

PEGylated chlorin e(6) photosensitizers were synthesized with tri(ethylene glycol) attached at the ester bond(s) for a 1:1 conjugate at the 17(3)-position, a 2:1 conjugate at the 15(2)- and 17(3)-positions, and a 3:1 conjugate at the 13(1)-, 15(2)-, and 17(3)-positions. These chlorin sensitizers were studied for hydrolytic stability and solubility, as well as ovarian OVCAR-5 cancer cell uptake,...

BACKGROUND Erythrina corallodendron lectin (ECorL) is one of the potent applied lectins. In previous studies, the carbohydrate specificities of this lectin were limited to monosaccharides, simple oligosaccharides and several clusters. However, the polyvalent factor has not been investigated. METHODS The binding properties at the combining sites of ECorL were characterized by sensitive enzyme-...

Unique three-component self-assembly of a cis-blocked 90° Pd(II) acceptor with a mixture of tri- and tetra-imidazole donors led to the self-sorting of a Pd7 molecular boat with an internal nanocavity, which catalyses the Knoevenagel condensation of a series of aromatic aldehydes with 1,3-dimethylbarbituric acid and Meldrum's acid in aqueous media.

Cinnamic acid derivatives bearing a nitroxyl moiety (2,2,6,6-tetramethyl-1-oxyl-4-piperidyl 3-E-aryl acrylates) were synthesized in 30-100% yield using a Mizoroki-Heck cross-coupling reaction between 4-acryloyloxy-2,2,6,6-tetramethylpiperidine-1-oxyl and iodobenzene derivatives in the presence of palladium(II) acetate coordinated with a tri(o-tolyl)phosphine ligand immobilized in a polyurea mat...
