Abstract: WDM multilayered SiC/Si devices based on a-Si:H and a-SiC:H filter design are approached from a reconfigurable point of view. Results show that the devices, under appropriated optical bias, act as reconfigurable active filters that allow optical switching and optoelectronic logic functions development. Under front violet irradiation the magnitude of the red and green channels are ampl...

Of the four classes of vertebrate cone visual pigments, the shortwave-sensitive SWS1 class shows the shortest lambda(max) values with peaks in different species in either the violet (390-435 nm) or ultraviolet (around 365 nm) regions of the spectrum. Phylogenetic evidence indicates that the ancestral pigment was probably UV-sensitive (UVS) and that the shifts between violet and UV have occurred...

Several papers have been published (Kennedy and Barbaro, 1953; Barbaro and Kennedy, 1954; Bartholomew and Finkelstein, 1954; Kennedy and Woodhour, 1956; Barbaro et al., 1956) on methods of comparing degrees of gram-positiveness and the influence of certain factors on the quantity of crystal violet retained by the microorganisms. These papers compare the degrees of gram-positiveness by measuring...

A new consortium of four bacterial isolates (Agrobacterium radiobacter; Bacillus spp.; Sphingomonas paucimobilis, and Aeromonas hydrophila)-(CM-4) was used to degrade and to decolorize triphenylmethane dyes. All bacteria were isolated from activated sludge extracted from a wastewater treatment station of a dyeing industry plant. Individual bacterial isolates exhibited a remarkable color-removal...

Ultraviolet (UV) reception is useful for such basic behaviors as mate choice, foraging, predator avoidance, communication, and navigation, whereas violet reception improves visual resolution and subtle contrast detection. UV and violet reception are mediated by the short wavelength-sensitive (SWS1) pigments that absorb light maximally (λmax) at ~360 nm and ~395 to 440 nm, respectively. Because ...

1. Acid fuchsin possesses a bactericidal power, selective as between Gram-negative and Gram-positive spore-bearing aerobic organisms. The selective feature is the reverse of that of gentian violet. 2. This reverse selective activity is also possessed by simpler sulfonated substances and would appear to be dependent in some way on the presence of SO(3) radicals. 3. Selective penetration, if at a...
