The title complex, [Cd(C(9)H(9)O(2)S)(2)(C(10)H(8)N(2))(H(2)O)(2)](n), has a linear chain structure. The central Cd(II) ion is in a slightly disorted octa-hedral environment, coordinated by two aqua ligands, two (4-tolyl-sulfan-yl)acetate ligands and two bridging 4,4'-bipyridine ligands. The Cd(II) ion lies on a twofold rotation axis. Inter-molecular O-H⋯O hydrogen bonds connect adjacent chains...

We demonstrate the feasibility of polycrystalline nitride semiconductor light-emitting diodes ~LEDs!. Here, polycrystalline LEDs were deposited on quartz substrates, incorporating a layer structure identical to that used for epitaxially grown LEDs. The deposition exhibits a tendency to produce c-oriented crystallites. Violet-blue ~430 nm! operation of a polycrystalline LED is demonstrated, with...

A dual function blue fluorescent protein from Vibrio vulnificus is also an NADPH-dependent oxidoreductase, rendering it a useful tool for biophysical studies.

The performance of a food-storing species, the marsh tit tParue palustris), was compared with that of a nonstorer, the blue tit (P. caeruleusi, in a spatial memory task in which birds had to return to a site where they had previously been allowed to eat part of a piece ofpeanut. No differences were found between species' overall performance, but increasing retention interval from 1 min to 24 h ...

The title compound, C(17)H(15)BrOS, was prepared by the Lewis acid-catalysed reaction of 2,4-dimethyl-phenol with 4'-bromo-2-chloro-2-(methyl-sulfan-yl)acetophenone. The 4-bromo-phenyl ring is rotated slightly out of the benzofuran plane, making a dihedral angle of 8.4 (1)°. The crystal structure is stabilized by a CH(2)-H⋯π inter-action between the 5-methyl group and the benzene ring of the be...

Oxidases are able to degrade organic pollutants; however, high costs associated with biocatalysts production still hinder their use in environmental biocatalysis. Our study compared the action of a commercial laccase from Aspergillus oryzae and a rich extract from Pleurotus ostreatus cultivation residues in decolourisation of reactive dyes: Drimaren Blue X-3LR (DMBLR), Drimaren Blue X-BLN (DMBB...

The absorption and scattering coefficient of a macroscopically homogeneous strongly scattering medium (lipid emulsion) containing Methylene Blue is quantitatively measured in the spectral range from 620 to 700 nm. We conduct the measurements in the frequency domain by using a light-emitting diode (LED) whose intensity is modulated at a frequency of 60 MHz. We derive an analytical expression for...

A red/green equilibrium light is one which appears neither reddish nor greenish (i.e. either uniquely yellow, uniquely blue, or achromatic). A subset of spectral and nonspectral red/green equilibria was determined for several luminance levels, in order to test whether the set of all such equilibria is closed under linear color-mixture operations. The spectral loci ofequilibrium yellow and blue ...

Threshold measurements of spectral sensitivity were obtained from a blue monocone monochromat using a foveal fixation target. The dark-adapted spectral sensitivity function could be represented by the luminosity function of the rods (CIE C\) weighted by xanthophyll. With a 6.2 troland (id) background the spectral sensitivity function was identical to that of the blue cones (Stiles iri) for wave...

The system for litigating patents has long been recognized as having significant positive and negative effects on innovative activity in the United States. Consequently, understanding patent litigation dynamics is of paramount importance. We study how infringement awards and other case outcomes affect patent litigation, and we mine a comprehensive dataset we have assembled comprising over 1,300...
