translate English to French: 19 The Board is not convinced by the counter-argument that the smell does not have a definite content, since it may be perceived differently due to various factors, being affected for example by the concentration and quantity, the temperature, the carrier material, the odorous substances, etc., as well as by subjective factors such as memories.
19 La chambre réfute l’argument selon lequel l’odeur est vague parce qu’elle peut être perçue sur la base de divers facteurs, influencée par la concentration et la quantité, la température, le support, les essences etc., ainsi que par des facteurs subjectifs comme les souvenirs.
