Even on the calmest day the atmosphere is normally in motion because convection currents (see below Convection) are set up by heat derived from sunlight that is released at the Earth's surface.
Solar dryers are classified according to their heating modes or the manner in which the heat derived from the solar radiation is utilized.
In [19], a survey of 1000 households using a heat pump to optimize the demand for switching between electricity and heat, derived from fixed gas prices and electricity prices vary from time to time.
It is believed that hydrothermal fluid flux is primarily controlled by the crust (magma) production rate, because magmatic heat derived from creation of new oceanic crust (cooling from 1,200°C to 350°C) heats hydrothermal fluids from 2°C to 350°C (e.g., Elderfield and Schultz 1996).
The heat change measured during the initial 3 min after mitochondria injection was discarded in order to avoid artifacts such as heat derived from the dilution of the mitochondria suspension in the reaction medium and binding of ions to mitochondria [18], [34].

Over-heating derived crystallization, which decreased the positive effect of β, caused the fracture toughness deterioration.
Therefore, the surface heat flow q 0 is given by: q_{0} = q_{text{c}} + q_{text{m}} = rho_{text{c}} + H_{text{c}} h_{text{c}} + q_{text{m}}, (6 where q c is the crustal heat flow derived from heat-producing elements (Eq. 5).
A second-law-based thermoeconomic model of a sensible heat-storage system with Joulean heating is derived and discussed in which the storage element is cooled by flowing stream of gases.
