This paper is a brief account of the moduli of complex curves from the perspective of noncommutative geometry. Using a uniformization of Riemann surfaces by the ordered abelian groups, we prove that modulo the Torelli group, the mapping class group of surface of genus g with n holes, is linear arithmetic group of rank 6g − 6 + 2n.

A series of new 1-[(2, 3-dichloroanilinomalonyl)]-3-(N-2’-cyanoethyl-N-2, 3-dichloroanilino)-5phenyl pyrazoline have been synthesized in 48 to 77% yield, by the reaction of N-cinnamoyl-N-2’cyanoethyl-2, 3-dichloroaniline with Ethyl-2-(2,3-dichloroanilido) acetohydrazide. Pyrazolines are yellow, cream and brown color solids, having high melting points. Identity of these products has been establi...

The blood-testis barrier (BTB), composed primarily of Sertoli cells, is responsible for protecting developing germ cells from xenobiotic exposure. ATP-binding cassette (ABC) membrane-associated drug efflux transporters, P-glycoprotein (P-gp), breast cancer resistance protein (BCRP), and the multidrug resistance-associated proteins (Mrps), have been shown to restrict antiretroviral drug permeabi...

About 80% of onion bulb dry matter is non-structural carbohydrates (Darbyshire & Henry, 1981). These carbohydrates are predominantly glucose, fructose, sucrose and low-molecular-weight fructans, while starch and raffinose are absent (Darbyshire & Henry, 1981; Benkeblia et al., 2002). The metabolism of sugars is closely linked to the dormancy and sprouting state (Kato, 1966), and the most import...

We have observed the compensation of loss in a metal by a gain in a dielectric medium in the mixture of an Ag aggregate and a Rhodamine 6G dye. The demonstrated sixfold enhancement of the Rayleigh scattering is the evidence of the enhancement of the surface-plasmon resonance. The reported experimental observation facilitates many applications of nanoplasmonics.

Using optical tweezers combined with luminescence measurements we detected the optical field around two optically trapped silica microspheres partially covered by metal. By monitoring the luminescence of rhodamine 6G we were able to observe an increase of the local field intensity owing to the coupling of the local surface plasmons at the surfaces of two spheres.

A solution-processed patterning of functional organic materials in emulsion is reported. The concept is to absorb microdrops onto predefined locations by hydrophilicity difference. Owing to a universal solvent used, the method can be applied to pattern variety materials on substrates of interest over large size. The figure shows Rhodamine 6G patterned film.

A fluorescence based cholesterol detection method has been developed using competitive host-guest interaction between graphene bound β-cyclodextrin (β-CD) with rhodamine 6G (R6G) and cholesterol. Fluorescence of β-CD incorporated R6G is quenched by graphene but is 'turned on' by cholesterol as it replaces R6G from the β-CD host.

The present investigation aims to synthesize the novel nanocomposite thin film and utilize material remove emerging dyes efficiently (i.e., Rhodamine B (R-B) 6G (R-6G)), in an aqueous solution using LED visible light UV-A light. A facile synthetic route was adopted obtain TiO<sub>2</sub>-supported bentonite <i>in situ</i> decorated with Au nanoparticles (NPs) film. advan...
