City
A city is a human settlement of a substantial size. The term "city" has different meanings around the world and in some places the settlement can be very small. Even where the term is limited to larger settlements, there is no universally agreed definition of the lower boundary for their size. In a narrower sense, a city can be defined as a permanent and Urban density, densely populated place with administratively defined boundaries whose members work primarily on non-agricultural tasks. Cities generally have extensive systems for housing, transportation, sanitation, Public utilities, utilities, land use, Manufacturing, production of goods, and communication. Their density facilitates interaction between people, government organisations, government organizations, and businesses, sometimes benefiting different parties in the process, such as improving the efficiency of goods and service distribution.

McMurdo Station
McMurdo Station is an American Antarctic research station on the southern tip of Ross Island. It is operated by the United States through the United States Antarctic Program (USAP), a branch of the National Science Foundation. The station is the largest community in Antarctica, capable of supporting up to 1,500 residents, though the population fluctuates seasonally; during the antarctic night, there are fewer than two hundred people.

Firefighting In Antarctica
Firefighting in Antarctica encompasses various organizations and procedures designed to fight fires on the continent of Antarctica. Firefighting in Antarctica is complicated by the harsh conditions of the continent, the remoteness of the locations to be serviced, and the importance of protecting life-supporting shelter from immolation. Conditions and considerations Although there are no wildfires in Antarctica, fire represents a serious threat to human activity. Antarctica is the windiest place on earth, so there are often winds sufficient to quickly fan any flames. Due to the low temperatures, liquid water is often hard to obtain in large quantity. Because of the harsh conditions, shelter is a necessity of life and significant loss of shelter to fire could be disastrous to the survival of a base's residents, exacerbated by the remoteness of the bases from outside aid. Because of this, bases in Antarctica are often designed to mitigate the devastation of a fire by being made up o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Methanol Poisoning
Methanol toxicity (also methanol poisoning) is poisoning from methanol, characteristically via ingestion. Symptoms may include an altered/decreased level of consciousness, poor or no coordination, vomiting, abdominal pain, and a specific smell on the breath. Decreased vision may start as early as twelve hours after exposure. Long-term outcomes may include blindness and kidney failure. Blindness may occur after drinking as little as 10 mL; death may occur after drinking quantities over 15 mL (median 100 mL, varies depending on body weight). Methanol poisoning most commonly occurs following the drinking of windshield washer fluid. This may be accidental or as part of an attempted suicide. Toxicity may also rarely occur through extensive skin exposure or breathing in fumes. When the body breaks down methanol it results in the creation of metabolite byproducts such as formaldehyde, formic acid, and formate which cause much of the toxicity. The diagnosis may be suspected when ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
