As set out in the Sustainable Development Goals, it is necessary to achieve universal and equitable access safe drinking water services for all world’s population. Appropriate treatment alternatives rural areas should be prioritised this goal. In work, a simplified system (SDWTS), which has great potential application small communities areas, was evaluated on pilot scale turbidity apparent colo...

The mechanism of Methylene Blue adsorption on acid activated carbon Vitex Negundo Stem (AAVNS) has been studied through batch experiments. Generally, dyes are organic compounds used as coloring products in chemical, textile, paper, printing, leather, plastics and various food industries. The need for the treatment of dye contaminated waste water passed out from the industry. In this study, Vite...

Pinot noir is a grape variety with thin skin, which means the extraction of colour and polyphenols more challenging than other red varieties. The aim this study was to investigate impact protein removal by adding bentonite prior fermentation on wine composition. Four treatments were conducted, including control without addition wines produced three different types bentonites before cold soaking...

Landfill leachate with a low BOD/COD ratio was electrochemically oxidized by means of a boron-doped diamond anode. In addition to organic matter removal, this study addressed the issue of formation of both chlorinated organic compounds and nitrate ions as a result of organic matter and ammonia and/or organic nitrogen electro-oxidation in the presence of chloride ions. A factorial design methodo...

statement of problem: the effect of mouth washes on discolouration of dental ceramics with different surface preparations is not well documented. objectives: this in-vitro study has been conducted to evaluate the effect of chlorhexidine (chx) mouth rinse on colour stability of overglazed (op), autoglazed, (ap) or polished porcelain (pop) specimens. materials and methods: the restorative materia...

Shadow removal can significantly improve the image visual quality and has many applications in computer vision. Deep learning methods based on CNNs have become most effective approach for shadow by training either paired data, where both underlying shadow-free versions of an are known, or unpaired images totally different with no correspondence. In practice, CNN data is more preferred given eas...

solid rectangles were yellow and in the debris were found yellow cylinders much smaller than the rectangles. The smell was suggestivje of bile salts. The fortifying effect of the sample on Jhe alcoholic heart extract, in the Wassermann reaction, was appreciably reduced. For the removal of the colour and smell the sample was submitted to four processes : (i) one gramme was subjected to negative ...

This paper presents a non-photorealistic rendering algorithm that produces "stylised-style" images by removing the soft shading from the image and by giving objects extra definition through black outlines. The method of shading removal is based on a model of the architecture of the human colour vision system. Some image results are provided and the possible extension of the algorithm using a ba...
