Design/Construction Guide: Diaphragms and Shear Walls
A diaphragm is a flat structural unit acting like a deep, thin beam. The term "diaphragm" is usually applied to roofs and floors. A shear wall, however, is a vertical, cantilevered diaphragm. A diaphragm structure results when a series of such vertical and horizontal diaphragms are properly tied together to form a structural unit. (See ...
Paper Making and Recycling | Paper Recycling | US EPA
Paper Making and Recycling. Over the centuries, paper has been made from a wide variety of materials such as cotton, wheat straw, sugar cane waste, flax, bamboo, wood, linen rags, and hemp.
