This paper reports the studies available on the characterization and chemical/biochemical analysis of natural dyes; extraction of colorants from different natural sources; effects of different mordants and mordanting methods; conventional and non-conventional methods of natural dyeing; physico-chemical studies on dyeing process variables and dyeing kinetics; development of newer shades and anal...

As part of a continuing research program aimed at plausible approaches to synthetic dyes based on toxicological considerations, a group of premetallized iron complexed monoazo dyes were synthesized as potential alternatives to presently used high volume Crand Cocontaining monoazo acid dyes for nylon and wool. This approach takes advantage of the environmentally friendly property of Fe, and draw...

Single Electron transistor have high integration density, ultra-low power dissipation, ultra-small size, unique coulomb blockade oscillation characteristics which makes an attractive technology for future low power VLSI/ULSI systems. The Single Electron Transistor have extremely poor driving capabilities so that direct application to practical circuits is a yet almost impossible, to overcome th...

Anatase TiO₂ nanoparticles (TNPs) are synthesized using the sol-gel method and loaded onto the surface of polyester-cotton (65/35) fabrics. The nanofabrics degrade formaldehyde at an efficiency of 77% in eight hours with visible light irradiation or 97% with UV light. The loaded TNPs display very little release from nanofabrics (~0.0%) during a standard fastness to rubbing test. Assuming TNPs m...

Two Visual Servoing controls respectively of the Position Based and Image Based type have been developed to govern a parallel translating manipulator with an eye-in-hand configuration. The robot must be able to reach and grasp a special target randomly positioned in the workspace; the control must be adaptive to compensate motions of the target in the 3D space. The implemented trajectory planni...

In this study, a fuzzy logic controller is developed using a new methodology for designing its rule-base. This controller consists of two rule-base blocks and a logical switch in between. The rule-base blocks admit two inputs one of which is newly devised and called “normalized acceleration” and the other one is the classical “error”. The newly devised input gives a relative value about the “fa...

Haml, P. B. (1974). Thorax, 29, 382-386. Primary pulmonary nocardiosis: a case report. A case of fulminating pulmonary nocardiosis is reported. Diagnosis was made before death but too late for treatment to be effective. At necropsy extensive multiple pulmonary abscesses with involvement of the pleura, resulting in an empyema, were discovered. One cervical node showed a similar abscess. No brain...

This study developed a novel pH-mediated antimicrobial dyeing process of cotton with prodigiosins nanomicelles produced by microbial fermentation. The average diameter of the pigment nanomicelles was 223.8 nm (range of 92.4–510.2 nm), and the pigment concentration was 76.46 mg/L. It was found that the superior dyeing effect of cotton fabric was achieved by adjusting the dye bath pH. When the pH...

Protease secreting microbe was isolated and characterized on the basis of their morphological, biochemical, physiological and 16S rDNA based molecular properties. The extracellular protease was quantified and characterized. Protease was used for different time (4, 8, 12 and 24 h) at different temperature (RT and 37°C) for optimization of the degumming process for raw silk fabric with enzyme dos...
