response

The dose–response relationship, or exposure–response relationship, describes the magnitude of the response of an organism, as a function of exposure (or doses) to a stimulus or stressor (usually a chemical) after a certain exposure time. Dose–response relationships can be described by dose–response curves. This is explained further in the following sections. A stimulus response function or stimulus response curve is defined more broadly as the response from any type of stimulus, not limited to chemicals.

    stupid boiler designs

    Went to a Glow worm extra fast which think is a saunier duval in disguise which had a dodgy thermistor. but why oh why is the pump head is facing the back of the boiler that must be a right git to change or bleed if you've got big hands like mine. why would you design it like that.
