Improvements include lower monomer odour together with control of both the reaction rate and the crosslinking reaction.
In the control media, organic acid was the highest category, and hydrogen sulphide and ammonia constituted the lower categories (odour index of the GYP media: organic acid, 23.5; hydrogen sulphide, 2.87; ammonia, 0.00).
During the breeding season the amount of manganese accumulation (after 1 hour of Mn2+ injection) with milfoil stimulus was significantly lower than without an odour.
Hibernation protects against predation by reducing the chance of detection via lowering levels of metabolism, having a cold and motionless body and lower emissions of body odours.
Also, chloramines further reduce taste and odour problems and produce lower levels of harmful by-products, compared with the use of chlorine alone.
Exposure to PNC and offensive odour, and nasopharyngeal irritation, can be significantly lowered when utilising a route of lower proximity to motorised traffic whilst bicycle commuting, without significantly affecting commute distance or duration.
Among the different inhalant anaesthetics, sevoflurane has several advantages, such as a lower blood-gas partition coefficient and a non-pungent odour, and it also provides rapid induction and recovery [ 9, 10].
It could be that, almost equal numbers of unfed mosquitoes were attracted by the odour but escaped to continue scavenging for blood source hence lower density of unfed An. gambiae s.l.l
Another example is called "flat sour," in which the spoiled product has an abnormal odour, a cloudy appearance, and a sour taste owing to its lowered pH.
Generally, higher wind velocities produced shorter odour plumes for all atmospheric conditions, but a shorter odour plume was observed also at lower wind velocities under unstable atmospheric stability because of stronger vertical convection.
