CO2 Emissions Profile of the U.S. Cement Industry

In the "wet" process, the ground materials are first mixed with water to form a slurry before being fed into the kiln. The use of the dry process for cement production has increased significantly in the last couple of decades (Figure 1), partially due to the lower fuel requirements for the dry process (discussed further below). In 1975, dry

Lithograph | The Metropolitan Museum of Art

Lithograph. Lithography is a planographic printmaking process in which a design is drawn onto a flat stone (or prepared metal plate, usually zinc or aluminum) and affixed by means of a chemical reaction. First, the design for the lithograph is drawn directly onto a polished slab of limestone using an oil-based lithographic crayon or ink.

Metal processing

This will strengthen the metal, making it harder to deform. This process is known as cold working. At higher temperatures the dislocations can rearrange, so little strengthening occurs. You can try this with a paper clip. Unbend the paper clip and bend one of the straight sections back and forth several times.
