in new management approaches, in the organizations with inflexible structure, existing of red tapes and interruptions caused by limitations and also non-compliance with environmental changes, create demotivation among staff. with regard to the influence of job motivational potential and its relationship to the type of organizational structure( enabling and dissuasive), the goal of this research...
A bacterial strain (strain PS) was isolated from the textile effluents carrying Serilene Black BNFS® (C.I. Disp. Blk. Mix) disperse dye. The isolate was able to decolorize the dye without the need for any exogenous carbon source. Full sequencing of its 16S rRNA indicated that Bacillus sp strain PS is related to Bacillus cereus groups. Silica- gel-thin layer chromatography of Ser...
Present work investigates the capability of oxidative treatment process in the presence of nano silver doped on silicate particles for decolorization of a widely used azo dye, C.I. Direct Blue 129 (DB129) in water samples. Solutions with initial concentration of 20 mgL-1 of dye, within the range of generic concentration in textile wastewaters, were treated under ambient conditions of initial pH...
The crystal structure of a cyanine dye rotaxane shows that the cyclodextrin is tightly threaded round the polymethine bridge of the dye; encapsulation dramatically increases the kinetic chemical stability of the radicals formed on oxidation and reduction of the dye, making it possible to observe the rotaxane radical dication by ESR and UV-vis-NIR spectroscopy.
Background and Purpose:Organic dyes with a complex structure are often toxic, carcinogenic, mutagenic, non-biodegradation and stable in the environment and if released to the environment without treatment can endanger the environment and human health. The aim was to evaluate the performance nanoscalezero-valent iron (NZVI) in the removal of dye acid red 18 (AR18) from aqueous solutions. Materia...
The purpose of this study was to investigate the effect of the reactive dye structure and type of penetrant in ink formulation on paper ink-jet printing. Different type of papers, which have same grammage was printed upon with three commercial reactive dyes, CI Reactive Blue 49 Ink 1, 4, CI Reactive Blue 21 Ink 2, Ink 5 and CI Reactive Blue 19 Ink 3, Ink 6, which are based on different reactive...
This review focuses on the optimization of optical performance polymer/dye blends in which dyes are physically dispersed polymer matrices. The is discussed terms of: (i) preparation procedure (melt processing considered particularly effective for producing with optimal dye distribution); (ii) mechanical and thermal solicitations after blend preparation; (iii) matrix, whose affinity crystallinit...
Textured polyester multifilament yam was subjected to swelling in single and mixed solvents (with varying ratio) at room temperature for different durations. The changes in the structure and properties of the yam were investigated by measuring birefringence, crystallinity, critical dissolution time, shrinkage on treatment, % change in bulk, residual shrinkage, crimp rigidity, dye uptake and dye...
The Adaptive Trade-Off between Detection and Discrimination in Cortical Representations and Behavior
It has long been posited that detectability of sensory inputs can be sacrificed in favor of improved discriminability and that sensory adaptation may mediate this trade-off. The extent to which this trade-off exists behaviorally and the complete picture of the underlying neural representations that likely subserve the phenomenon remain unclear. In the rodent vibrissa system, an ideal observer a...
