As the world uses more and more mobile electronic products, controlling power consumption is the primary limiter of scaling semiconductor process technologies and adding features to integrated circuits.
During farrowing, sows (adult female pigs) give birth to piglets in special rooms designed to provide for the special needs of the animals. These areas typically are separate from other areas of the farm where pigs may be housed and they are rotated to other barns to control the spread of disease. The stalls reduce the number of piglets that are accidentally laid on or stepped on by the sow, temperature control technology allows piglets to stay warm while sows keep cool.
Livestock and their byproducts account for at least 32,000 million tons of carbon dioxide (CO2) per year, or 51% of all worldwide greenhouse gas emissions.
