Use of radiation to generate heat such as with baseboard heating where the circulating hot water is radiated through conduction by thin metal fins at the bottom of the wall. The room is warmed by air circulating around the heating unit using convention.
Heating unit that is exposed and which transfers heat generated by hot eater or steam through conduction. When the air circulates around the radiator using convention, the room is heated.

2. The horizontal sections of a panel door.
3. The top and bottom sections of a window sash.
Waterproof cap, also called weatherheads, mast heads or entrance caps, which is placed at the upper part of an electrical mast at the point where the wires are run to the inside electrical meter. Wires hang from the pole to the entrance cap so that the entrance cap is not the low point in the downhill run from the pole because water will run to the low point before dripping to the ground. Wires enter the entrance cap at an upward angle through a tight insulator. Water is further stopped from getting through the entrance cap because of this entrance angle.
Wood where the fibers have swelled, usually because of becoming wet. Wood is often sanded with the grain raised to achieve an extremely smooth finished surface.
1. A fork-like tool used for gathering materials (i.e. leaves) or smoothing an area of soil.
