  2. Lithium-ion battery - Wikipedia

    en.wikipedia.org/wiki/Lithium-ion_battery

    A lithium-ion or Li-ion battery is a type of rechargeable battery that uses the reversible intercalation of Li + ions into electronically conducting solids to store energy. In comparison with other commercial rechargeable batteries, Li-ion batteries are characterized by higher specific energy, higher energy density, higher energy efficiency, a longer cycle life, and a longer calendar life.

    en.wikipedia.org/wiki/Smallpox

    Smallpox was an infectious disease caused by variola virus (often called smallpox virus), which belongs to the genus Orthopoxvirus. [7] [11] The last naturally occurring case was diagnosed in October 1977, and the World Health Organization (WHO) certified the global eradication of the disease in 1980, [10] making smallpox the only human disease to have been eradicated to date.

  4. Cattle - Wikipedia

    en.wikipedia.org/wiki/Cattle

    Being prey animals, cattle evolved to look out for predators almost all around, with eyes that are on the sides of their head rather than the front. This gives them a field of view of 330°, but limits binocular vision (and therefore stereopsis) to some 30° to 50°, compared to 140° in humans. [27] They are dichromatic, like most mammals. [35]

  5. Cat - Wikipedia

    Another common reason for fighting in domestic cats is the difficulty of establishing territories within a small home. [122] Female cats also fight over territory or to defend their kittens. Neutering will decrease or eliminate this behavior in many cases, suggesting that the behavior is linked to sex hormones .

    en.wikipedia.org/wiki/Thermoelectric_generator

    The typical efficiency of TEGs is around 5–8%, although it can be higher. Older devices used bimetallic junctions and were bulky. More recent devices use highly doped semiconductors made from bismuth telluride (Bi 2 Te 3), lead telluride (PbTe), [10] calcium manganese oxide (Ca 2 Mn 3 O 8), [11] [12] or combinations thereof, [13] depending on application temperature.
