Separation is achieved in the way that rubber smoke oil and dust are separated and collected through physical spraying; decomposition is achieved in the way that sulfide mainly containing sulfur dioxide is decomposed and reacted through NaOH solution to generate sodium sulfate soluble in water; and ...
In rodents, chronic infection alters fear, smell, reward pathways, neurotransmitters such as GABA and dopamine, and causes abnormal neurologic functions15. Although this parasite is present in the brains of 2–3 billion persons worldwide, consequences are unknown. Neurobehavioral abnormalities and ...
queens often release rectal fluid with a strong smell of grapes, after which they temporarily stop fighting. The fluid, which includes o-aminoacetophenone, has an effect on behavior of worker bees. In small groups, the exemplary compound o-aminoacetophone repels bees and helps to terminate ago...
which can foul the treatment fluid and create an unpleasant smell. Some microorganisms can produce hydrogen sulfide (H2S) gas as a respiration end product, which accumulates extracellularly during consumption. It is undesirable for a well to contain high amounts of a sour gas, such as...
In a number of processes, such as the refining of crude oil, the purification of natural gas and the production of synthesis gas from, for example, fossil fuels, sulfur containing gas, in particular H2S containing gas, is released. On account of its high toxicity and its smell, the emissio...
Such an oxidation produces a dark brown coloration of the extracts and a pungent smell, rendering same relatively incompatible with use in cosmetics. Along these lines, a laccase, the molecular weight of which is greater than 100,000 daltons, is, in particular, known. ...
from about 0% to about 10%, by weight of the composition, of solubilized, water-soluble metallic salt, aqueous carrier and wherein said composition is essentially free of any material that would soil or stain fabric and wherein said composition is essentially free of perfume and has a pH of...
These had been collected and could be distinguished on the basis of colour, texture, weight, and flame colour and smell when heated. The notably greater yield obtained by heating native copper with associated oxide minerals may have led to the smelting process, since these oxides are easily ...
