Graffiti can create detrimental aesthetic and environmental damage to city infrastructure cultural heritage requires improved removal methods. Incumbent laser, mechanical chemical techniques are often not effective, expensive or the substrate. Solvents generally hazardous always effective because of insolubility graffiti paint. This study proposes a simple strategy for safe removal, using bio-b...

The reactive dye Cibacron Yellow S-3R was selected to evaluate the feasibility of combining nanofiltration membranes with electrochemical processes to treat textile wastewater. Synthetic dyeing effluents were treated by means of two nanofiltration membranes, Hydracore10 and Hydracore50. Up to 98% of dye removal was achieved. The influence of salt concentration and pH on membrane treatment was s...

The purpose of the present study was to determine which augmented sensory modality would best develop subjective error-detection capabilities of learners performing a spatial-temporal task when using a touch screen monitor. Participants were required to learn a 5-digit key-pressing task in a goal time of 2550 ms over 100 acquisition trials on a touch screen. Participants were randomized into 1 ...

Animal colouration is typically the product of nanostructures that reflect or scatter light and pigments that absorb it. The interplay between these colour-producing mechanisms may influence the efficacy and potential information content of colour signals, but this notion has received little empirical attention. Wing scales in the male orange sulphur butterfly (Colias eurytheme) possess ridges ...

: The CIECAM97s and its revision, as a colour appearance model, were applied for a series of fabrics with different colours and depths to explain their colour appearance coordinates in similar viewing conditions. The results show that due to some modifications which expand the scale, the modified model has improved capadilities in calculating chroma. Besides, the calculations were simpler for t...

Recently, low-cost adsorbents from sustainable sources are required for the remediation of textile wastewater. Carbonized Orange Peels (COPs) was utilized in remediating colour, Zinc and Copper The initial final pH, colour trace metals’ composition wastewater used were determined adsorption processes. Batch experiment carried out on COPs wastewater’s mixture to find effects COP’s dosage, agitat...
