Bifenthrin is poorly soluble in water and often remains in soil. Its residual half-life in soil is between 7 days and 8 months, depending on the soil type, with a low mobility in most soil types. Bifenthrin has the longest known residual time in soil of insecticides currently on the market. It is a white, waxy solid with a faint sweet smell.
For example, the isotope copper-64, commonly used in medical research, has a half-life of 12.7 hours. If you inject a large group of animals at "time zero", but measure the radioactivity in their organs at two later times, the later groups must be "decay corrected" to adjust for the decay that has occurred between the two time points.
An equianalgesic chart can be a useful tool, but the user must take care to correct for all relevant variables such as route of administration, cross tolerance, half-life and the bioavailability of a drug. [5] For example, the narcotic levorphanol is 4–8 times stronger than morphine, but also has a much longer half-life. Simply switching the ...
Each additional year of the dog’s life is then multiplied by between 4.3 and 13.4 years, depending on the breed, to find their human age. American Kennel Club The stages of a dog’s life
Peak-to-trough ratio in pharmacokinetics is the ratio of peak (C max) and trough (C min) levels of a drug over its dosing interval (τ) at steady state.. Peak-to-trough ratio (PTR), also known as peak-to-trough variation or peak-to-trough fluctuation, is a parameter in pharmacokinetics which is defined as the ratio of C max (peak) concentration and C min (trough) concentration over a dosing ...
1. Ketogenic Diet. Cancer cells rely on glucose for energy to grow. The ketogenic diet is a way to provide an alternative energy source to normal cells in the dog's body while starving the cancer ...

Etofenprox's half-life in aerobic soil is between 7 and 25 days. [6] One study showed it to have a half-life of 3 weeks on bean leaves. [ 7 ] Another study showed it to have a half-life of 1 week on rice plants.
