Active ingredient concentration If the concentrations of the active ingredient(s) in the two products that are bridged are the same, bridging is facilitated. However, it should be emphasized that in many cases, the concentration of the a.i. in the formulation does not significantly affect risk (e.g. for dietary risk, surface water risks, soil organisms or pollinators, it is the application rate that is a key risk factor, not the pesticide concentration in the product). In some cases, the a.i. concentration in the product may be important for bridging; e.g. for operator risk assessment, when mixing and loading is done using the concentrated product.

Category 2), dose/concentration ‘guidance values’ are provided for consideration of the dose/concentration which has been shown to produce significant health effects. (...) If the latter occurs, new classification is necessary.
Concentration of Highly Toxic Mixtures
35. If in a mixture of category 1, the concentration of a toxic ingredient is increased, the concentrated mixture should be classified in category 1 without additional testing.
(...) The concentration of ingredient A in mixture (i) equals that of ingredient C in mixture (ii) d).

CHIRAL OPTICAL CHANNEL by diffusion, meaning that the particles move from areas In the context of molecular communication, we envision of higher concentration to areas of lower concentration, that chiral molecules will be expected to be largely ex‑ and the displacement of messenger molecules follows a ploited [25]. Due to the feature of changing the polariza‑ normal distribution with zero mean. tion plane of an impinging optical signal, data information The overall chiral molecule concentration lux is given can be encoded into chiral molecules, and carried out via by the sum of the chiral molecules concentration gra‑ the chiral transfer mechanism. (...) The lux of chiral molecule concentration activity as output of the channel will be observed.

To ensure the concentrators arrived as quickly and safely as possible, UNICEF and The UPS Foundation teamed up in a rapid logistics effort to send 500 concentrators to Kolkata, the capital of West Bengal, for distribution in the state. This delivery of oxygen concentrators was just the beginning of a response that saw UPS support the delivery of over 3,000 concentrators to India.
(...) Those suffering from acute breathlessness get some relief when they are provided with oxygen from the concentrators.”
