Background Cardiac implantable electric devices are commonly used to treat heart failure. Little is known about temporal and geographic variation in use of cardiac resynchronization therapy (CRT) devices in usual care settings.
A hammer drill, also known as a rotary hammer, roto-drill or hammering drill, (see also rotary drill) is a rotary drill with a hammering action. The hammering action provides a short, rapid hammer thrust to pulverize relatively brittle material and provide quicker drilling with less effort.
The rotational molding (also known as rotomold) process is a high-temperature, low-pressure plastic forming process that uses heat and biaxial rotation (i.e., rotation on two axes) to produce hollow, one-piece parts. The YETI cooler mold is loaded with polyethylene in powder form.
