A first-order derivative spectrophotometric method for the simultaneous determination of three textile dyes, Procion Yellow HE4R, Procion Red HE7B and Remazol Black 5 (RB5), has been developed. The effects of pH, heating and ionic strength of the solution on the absorption spectra of the dyes were investigated. The wavelengths selected for the measures of the derivative signals of HE4R (395 nm)...

The present work deals with the ways of testing the compatibility of reactive dyes with cotton in different textile industries in Bangladesh. This report includes three laboratory trials that were carried out for three different reactive dyes to check the compatibility for use in a dye recipe on cotton knitted goods. In this study, Spectrophotometric analysis was conducted and the fixation of e...

In this study, it was attempted to determine the resistance of different tomato lines spotted wilt virus (TSWV), yellow leaf curl (TYLCV), and root-origin nematodes (Meloidogyne spp.) using molecular DNA markers. For purpose, out 96 be tested, Sw5-2 for ripening Ty3P6-25 (TYLCV) marker Mi23, which determines root-knot spp.), were used by PCR. Ty3P6-25, that TYLCV, found susceptible (rr) in 34 l...

We show that the stochastic Morris-Lecar neuron, in a neighborhood of its stable point, can be approximated by a two-dimensional Ornstein-Uhlenbeck (OU) modulation of a constant circular motion. The associated radial OU process is an example of a leaky integrate-and-fire (LIF) model prior to firing. A new model constructed from a radial OU process together with a simple firing mechanism based o...

Remazol Yellow FG is a thiazine dye widely used in textile industries. This compound difficult to degrade naturally. One method that can be for wastewater treatment the Advanced Oxidation Process with heterogeneous Fenton reaction. The reaction mechanism uses H2O2 as an oxidizer and iron nanoparticles catalyst. material catalyst support activated carbon. Activated carbon modified because it has...

F1-A(y) mice between RR (aabbCC) and C57BL/6J-A(y) (A(y)aBBCC) have a much darker yellow coat color than do C57BL/6J-A(y) . Quantitative trait locus (QTL) analysis was carried out to identify genes responsible for the darker modification of the yellow coat color (this has been traditionally termed "sable"). A significant sable QTL was identified on chromosome 1 (Dmyaq4, LOD score 15.5 for light...
