2(two) is a number, digit and digit. It is the natural number after 1 and before 3. It is the smallest and only even prime number. Because it forms the basis of a duality, it has religious and spiritual meaning in many cultures.
3(three) is a number, digit and digit. It is the natural number after 2 and before 4, the smallest odd prime and the only prime before a square. It has religious or cultural significance in many societies.
TheArctic(or) is a polar region in the northernmost part of the earth. The Arctic consists of the Arctic Ocean, adjacent seas and parts of Canada (Yukon, Northwest Territories, Nunavut), Danish Empire (Greenland), northern Finland (Lapland), Iceland, northern Norway (Finnmark and Svalbard), Russia (Murmansk, Siberia, Nenets Okrug, Novaya Zemlya), northernmost Sweden and the United States (Alaska). The land in the Arctic has seasonally variable snow and ice coverage with mostly treeless permafrost (permanently frozen underground ice) containing tundra. The Arctic seas contain seasonal sea ice in many places.
The Arctic region is a unique area among the Earth's ecosystems. The cultures in the region and the arctic aborigines have adapted to the cold and extreme conditions. Life in the Arctic includes zooplankton and phytoplankton, fish and marine mammals, birds, land animals, plants and human societies. The arctic country is bounded by the subarctic.

ATypeis a hinged or otherwise movable barrier that allows entering (entering) into and exiting (exit from) an enclosure. The created opening in the wall is aTypeorPortal. The essential and primary purpose of a door is to provide security by controlling access to the passageway (portal). Traditionally, it is a panel that fits into the doorway of a building, room or vehicle. Doors are generally made from a material suitable for the door's task. They are usually attached with hinges, but can also move in other ways, e.g. B. by sliding or balancing.
The door can move in a variety of ways (at angles away from the doorway/portal, by sliding on a plane parallel to the frame, by folding at angles on a parallel plane, or by rotating along an axis at the center of the door frame). frame) to allow or prevent entry or exit. In most cases, the inside of a door is the same as the outside. But in other cases (e.g. a vehicle door) the two sides are radically different.
Many doors have locking mechanisms to ensure only a few people can open them (e.g. with a key). Doors may have devices such as door knockers or doorbells that allow people outside to announce their presence. (In some countries, such as Brazil, clapping from the sidewalk to announce one's presence is common.) In addition to providing access in and out of a room, doors can serve the secondary function of providing privacy by preventing unwanted attention from outsiders. Separating areas with different functions, letting light in and out of a room, controlling ventilation or drafts so that interior spaces can be heated or cooled more effectively, deadening noise and preventing the spread of fire.
Doors can have aesthetic, symbolic, ritual purposes. Obtaining the key to a door can mean a change in status from outsider to insider. Doors and passageways often appear in literature and art with metaphorical or allegorical meaning as signs of change.
Königis the title bestowed on a male monarch in various contexts. The female equivalent is queen, whose title is also bestowed on a king's consort, although in some cases the royal title is bestowed on women, as in the case of Mary, Queen of Hungary.
- In the context of prehistory, antiquity, and contemporary indigenous peoples, the title may refer to tribal kingship. Germanic kingship is related to the Indo-European traditions of tribal rule (cfswear, gothicneed, and Old Irishfind, etc.).
- In the context of classical antiquity, king in Latin can be translated asRexand in Greek asArchonorBasil.
- In classical European feudalism, the title isKönigas ruler of akingdomis understood as the highest rank in the feudal order, possibly at least nominally subject to only one emperor (in paraphrase of the vassal kings of the Roman Republic and Roman Empire).
- In a modern context, the title may refer to the ruler of one of several modern monarchies (either absolute or constitutional). The title ofKönigused for monarchs alongside other titles: in the west, emperor, grand duke, prince, archduke, duke, or grand duke, and in the Islamic world, malik, sultan, emir, or hakim, etc.
- The city-states of the Aztec Empire had a Tlatoani who were kings of pre-Hispanic Mesoamerica. The Huey Tlatoani was the emperor of the Aztecs.
The termKönigmay also refer to a king's consort, a title sometimes given to a reigning queen's husband, but the title of prince consort is more common.
ARefrigerator, colloquialRefrigerator, is a commercial and domestic appliance consisting of a thermally insulated compartment and a heat pump (mechanical, electronic or chemical) that transfers heat from its interior to its external environment, cooling its interior to a temperature below room temperature. Refrigeration is an essential food storage technique around the world. The lower temperature lowers the rate at which bacteria multiply, so the refrigerator reduces the rate of spoilage. A refrigerator maintains a temperature a few degrees above the freezing point of water. The optimum temperature range for storing perishable food is 3 to 5°C (37 to 41°F). A similar device that maintains a temperature below the freezing point of water is called afreezer. The refrigerator replaced the ice box, which was a common household appliance for nearly a century and a half. The United States Food and Drug Administration recommends keeping the refrigerator at or below 4°C (40°F) and the freezer set to -18°C (0°F).
The first cooling systems for food were ice. Artificial cooling began in the mid-1750s and developed in the early 19th century. In 1834 the first working vapor compression refrigeration system was built. The first commercial ice machine was invented in 1854. In 1913, refrigerators for home use were invented. In 1923, Frigidaire introduced the first self-contained unit. The introduction of freon in the 1920s expanded the refrigerator market in the 1930s. Domestic freezers as separate compartments (larger than needed just for ice cubes) were introduced in 1940. Frozen food, once a luxury item, has become commonplace.
Freezers are used in households as well as in industry and commerce. Commercial refrigerators and freezers predated the current household models by almost 40 years. The freezer-over-fridge style was the basic style since the 1940s, until modern side-by-side refrigerators broke the trend. A vapor compression cycle is used in most domestic refrigerators, refrigerators and freezers. Newer refrigerators may include automatic defrost, chilled water, and ice from an in-door dispenser.
Domestic food storage refrigerators and freezers are manufactured in a range of sizes. Among the smallest are Peltier refrigerators, which are designed to chill beverages. A large domestic refrigerator is about the size of a person and can be about 1 meter (3 ft 3 in) wide with a capacity of 0.6 m3(21ft). Fridges and freezers can be freestanding or built into a kitchen. The refrigerator allows the modern household to keep food fresher longer than before. Freezers allow people to buy perishable foods in bulk and eat and make bulk purchases in peace.
