A Chevalley type integral basis for the ortho-symplectic Lie superalgebra is constructed. The simple modules of the ortho-symplectic supergroup over an algebraically closed field of prime characteristic not equal to 2 are classified, where a key combinatorial ingredient comes from the Mullineux conjecture on modular representations of the symmetric group. A Steinberg type tensor product theorem...

UV/TiO2 photocatalysis of chelated copper in aqueous solutions has been performed starting from Cu(II)-tartaric acid, Cu(II)-citric acid, Cu(II)-EDTA and Cu(II)-DTPA,in the presence of oxygen and at acidic pH. The photocatalytic reaction obeys first-order kinetic equation. The influence of Cu(II) on photocatalytic oxidation of organic ligands and how the various organics will affe...

This study was conducted to assess the compatibility of aspirin with selective amino acids by studying the effect of amino acids on the solubility of aspirin, so that the attention could be paid towards the use of proteinous foods along with aspirin. Two different types of dissolution media, i.e., 0.5% solution of each amino acid and 100 mL of distilled water (100 mL each), were prepared. Then,...

The 1 : 2 adduct of 1-bromo-ortho-carborane and pyridine has been identified as a significant intermediate in the deboronation of ortho-carborane to a nido-anion.

The synthesis of tetra-ortho-substituted biaryl naphthalenes, including examples bearing multiple ortho-isopropyl groups, has been developed via a catalytic rearrangement process.

The kinetics of growth for chiral J-aggregates of H(4)TPPS(4) porphyrin have been investigated under different experimental conditions in the presence of tartaric acid. The observed rate constants and the anisotropy factor g show a defined dependence on the enantiomer used as a chiral templating agent.

In the crystal structure of the title compound {alternative name: 1-[1-(2-hydroxy-phen-yl)ethyl-ideneamino]-3-(1H-indol-3-ylmethyl-eneamino)urea}, C(18)H(17)N(5)O(2), the planar indole component is twisted at an angle of 63.7 (10)° with respect to the rest of the mol-ecule. This compound is one of a series being studied for biological activity. The hydr-oxy groups are involved in both intra-mol...

Orthokeratology practice in children in a university clinic in Hong Kong Clin Exp Optom, 2008. 91(5): p. 453-60. PURPOSES: The aim of this study was to analyse clinical data of children undergoing orthokeratology (ortho-k) and to investigate patients'/parents' perspective on ortho-k via telephone interviews. METHODS: Clinical records of children undergoing ortho-k from a university optometry cl...

Molecular modelling of an iodine(III) phenoxide was used as a starting point in the design of chiral aryl iodide catalysts for stereoselective oxidative dearomatization reactions. Using this approach, catalysts derived from 8-iodotetralone and tartaric acid were constructed and used to synthesize enantioenriched para-quinols from phenols.
