Pollen count count is by using a Burkard Trap, also known as the seven-day volumetric spore trap. This device works by facing towards the wind and drawing in air by using a pump. The pollen particles drawn in by the pump are then trapped by a sticky wax film that is attached to a rotating drum. The drum slowly rotates one turn over the course of seven days while collecting particles. The tape is removed after one week and cut into day-length sections. Pollen count Pollen count is the measurement of the number of grains of pollen in a cubic meter of
Decay theory that older memories (in long-term memory) are often more resistant to shocks or physical attacks on the brain. It is also thought that the passage of time alone cannot cause forgetting, and that decay theory must also take into account some processes that occur as more time passes. The term "decay theory" was first coined by Edward Thorndike in his book "The Psychology of Learning" in 1914. This simply states that if a person does not access and use the memory representation they have formed the memory trace will fade or decay over time. This theory was based on the
