The first group used educational software via fixed agent, the second group used educational software with the option to choose among several agents whereas the third group used educational software without agent and the fourth group received the same education through traditional way.
Terrell James, Mr. Armstrong's wife and an abstract painter, first has them polished, then treats them with a compound of acid, pigment and fixing agents.
In addition to their use in analytical chemistry, heteropoly compounds have found use as catalysts, molecular sieves, corrosion inhibitors, photographic fixing agents, and precipitants for basic dyes.
Greatly reduced processing times are possible with high-activity developers at elevated temperatures and with fast-acting fixing agents, such as ammonium thiosulfate.
Its process modifies cotton's molecular structure and allows dye to settle within the fibres without requiring the massive discharge of water, eliminating the need to rise off fixing agents that keep a fabric's colouring consistent.
As dyeing of nylon is particularly difficult, acid dyes, fixing agents, thickeners, finishing agents, are required for successful colouration and cause major problems with the plant's effluent disposal in terms of chemical oxygen demand (COD).
Further, the fixing solution was aspirated and traces of fixing agents were removed by rinsing several times with PBS.
Rivers run red, magenta and blue with heavy-metal dyes, bleaches, solvents, fixing agents and detergents from dye houses around the world, including ones that bleed into essential water sources like the Noyyal River in India and Yangtze River in China.
The heads were fixed using different fixing agents (Table 1).
R&D investigations are required for the use of additives such as fixing agents, brighteners, alternative (natural) dyestuffs and pigments, UV stabilizers and other auxiliary chemicals suitable for improving wet processing technologies for coir fibres manufacture.
