textile industries use different chemicals in indigo dyeing processes. interest in eco-friendlyprocessing in the textile industry has recently increased because of a larger awareness of environmental issues. for the case of indigo dyeing process, the reducing agent conventionally used is the - environmentally unfavourable – sodium dithionite, which will be replaced in this study with an ecologi...
Indigo is one of the most consumed dyes in the textile sector, as it is widely used for the dyeing of denim clothes. About 15% of indigo used in the dyeing process is discharged to the wastewater treatment plants or sometimes into rivers, in countries where regulations are not strictly applied. In this work, real effluents that contained indigo dye were treated by means of 4 different ultrafilt...
Polygonum tinctorium Ait. (Polygonaceae) known as dyerís knotweed is an annual plant growing in the sandy and loamy soils of China, Japan and Eastern Russia, where it is cultivated for both industrial and pharmacological usage (1). Indigo one of its main constituents has been widely used in traditional chinese medicine, and also, as a natural dye, in the production of denim. Although its synthe...
Indigo carmine has been used for eight decades with few adverse effects. Several of our patients, however, experienced severe hypotensive episodes after indigo carmine administration within a period of one month. Analysis of the raw materials used to formulate the preparation of indigo carmine we used showed that they contained impurities. Following recall of these impure materials, none of our...
OBJECTIVE To determine if IndiGO individualized clinical guidelines could be implemented in routine practice and assess their effects on care and care experience. METHODS Matched comparison observational design. IndiGO individualized guidelines, based on a biomathematical simulation model, were used in shared decision-making. Physicians and patients viewed risk estimates and tailored recommen...
Indigo carmine is a typical recalcitrant dye which is widely used in textile dyeing processes. Laccases are versatile oxidases showing strong ability to eliminate hazardous dyes from wastewater. However, most laccases require the participation of mediators for efficient decolorization of indigo carmine. Here we describe the improvement of the decolorization ability of a bacterial laccase throug...
Recently, it was proposed that neutrophils generate ozone (Wentworth, P. J., McDunn, J. E., Wentworth, A. D., Takeuchi, C., Nieva, J., Jones, T., Bautista, C., Ruedi, J. M., Gutierrez, A., Janda, K. D., Babior, B. M., Eschenmoser, A., and Lerner, R. A. (2002) Science 298, 2195-2199; Babior, B. M., Takeuchi, C., Ruedi, J., Gutierrez, A., and Wentworth, P. J. (2003) Proc. Natl. Acad. Sci. U. S.

The intrinsic photophysics of indigo has been studied using gas-phase time-resolved photoelectron imaging of the indigo carmine dianion (InC(2-)). The action spectrum reveals that the gas-phase absorption spectrum arising from the S(1) <-- S(0) transition in InC(2-) has a similar solvent shift to that of neutral indigo. Femtosecond spectroscopy shows that the S(1) state decays on a 1.4 ps times...
In software engineering, the quality of processes and their models is of utmost importance for the quality of the software products developed. Nevertheless, many organizations neglect these processes and leave the knowledge about them in the heads of their experts. In this paper we present the indiGo method for eParticipative Process Learning based on eDiscussions, Lessons Learned, text mining,...
