Weapon Of Mass Destruction
A weapon of mass destruction (WMD) is a biological, chemical, radiological, nuclear, or any other weapon that can kill or significantly harm many people or cause great damage to artificial structures (e.g., buildings), natural structures (e.g., mountains), or the biosphere. The scope and usage of the term has evolved and been disputed, often signifying more politically than technically. Originally coined in reference to aerial bombing with chemical explosives during World War II, it has later come to refer to large-scale weaponry of warfare-related technologies, such as biological, chemical, radiological, or nuclear warfare. Early usage The first use of the term "weapon of mass destruction" on record is by Cosmo Gordon Lang, Archbishop of Canterbury, in 1937 in reference to the bombing of Guernica, Spain: At the time, nuclear weapons had not been developed fully. Japan conducted research on biological weapons, and chemical weapons had seen wide battlefield use ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Weighted Mean
The weighted arithmetic mean is similar to an ordinary arithmetic mean (the most common type of average), except that instead of each of the data points contributing equally to the final average, some data points contribute more than others. The notion of weighted mean plays a role in descriptive statistics and also occurs in a more general form in several other areas of mathematics. If all the weights are equal, then the weighted mean is the same as the arithmetic mean. While weighted means generally behave in a similar fashion to arithmetic means, they do have a few counterintuitive properties, as captured for instance in Simpson's paradox. Examples Basic example Given two school with 20 students, one with 30 test grades in each class as follows: :Morning class = :Afternoon class = The mean for the morning class is 80 and the mean of the afternoon class is 90. The unweighted mean of the two means is 85. However, this does not account for the difference in number of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wiggle Matching
Wiggle matching, also known as ''carbon–14 wiggle-match dating'' (WMD) is a dating method that uses the non-linear relationship between 14C age and calendar age to match the shape of a series of closely sequentially spaced 14C dates with the 14C calibration curve. A numerical approach to WMD allows one to assess the precision of WMD chronologies. The method has both advantages and limitations for the calibration of individual dates. High-precision chronologies are needed for studies of rapid climate changes. Andrew Millard refers to wiggle matching as a way of dealing with the flat portion of the carbon 14 calibration graph that is known as the Hallstatt plateau, named after the Hallstatt culture The Hallstatt culture was the predominant Western Europe, Western and Central European archaeological culture of the Late Bronze Age Europe, Bronze Age (Hallstatt A, Hallstatt B) from the 12th to 8th centuries BC and Early Iron Age Europe (Hallst ... period in central Europe wit ...

Wymondham Railway Station
Wymondham railway station is a stop on the Breckland Line in the East of England, serving the market town of Wymondham, Norfolk. The line runs between in the west and in the east. It is situated between and Norwich, from London Liverpool Street via . The station is managed by Greater Anglia, which also operates most of the services calling at the station; some East Midlands Railway services also stop here. Wymondham is also at a junction with the Mid-Norfolk Railway, a heritage route to ; those services operate from a separate station, , which is approximately one mile away. Wymondham was also once the junction of a branch line to , via . In 2017, the station's bistro was described in a BBC article. History The Bill for the Norwich & Brandon Railway (N&BR) received Royal Assent on 10 May 1844. Work started on the line in 1844 and the line and its stations were opened on 30 July 1845. Wymondham station opened with the line and was, when it opened, situated east of an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Westmead Railway Station
Westmead railway station is located on the Main Western railway line, Main Western line, serving the Sydney suburb of Westmead, New South Wales, Westmead. It is served by Sydney Trains suburban North Shore & Western Line, T1 Western Line and Cumberland Line, T5 Cumberland Line services and intercity Blue Mountains Line services. Additionally, light rail L4 Westmead & Carlingford Line services terminate at Westmead, allowing for interchange with heavy rail services. History Westmead station opened in March 1883. To the east of the station lies a dive through which one of the eastbound tracks passes. This was opened in 1986 as part of the quadruplication of the Main Western railway line, Main Western line between Westmead and Granville, New South Wales, Granville. It was necessary because west of Westmead the two westbound tracks run adjacent to one another as do the two eastbound tracks. East of Westmead, the westbound and eastbound tracks alternate. Between 1922 and 1932, the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mamaindê Language
Mamaindê, also known as Northern Nambikwara, is a Nambikwaran language spoken in the Mato Grosso state of Brazil, in the very north of the indigenous reserve, Terra Indígena Vale do Guaporé, between the Pardo and Cabixi Rivers. In the southern part of the reserve, speakers of Sabanê and Southern Nambikwara are found. History At the start of the 1900s, there were an estimated 3000 Mamaindê members. Their endangerment arose as a result of various intertribal wars and massacres in the 30s and 40s as well as measles outbreaks, leaving them with only 50 Mamaindê members by 1965 according to SIL workers Peter and Shirley Kingston. Their population began to rebuild in the 90s, according to SIL workers Dave and Julie Eberhard, when they traced a steady increase in population size and found that their community had grown to 136 members by 1999. Traditionally located in the Cabixi river region, the Mamaindê people belong to the Nambikwara language family. This language family ...

World Malaria Day
World Malaria Day (WMD) is an international observance commemorated every year on 25 April and recognizes global efforts to control malaria. Globally, 3.3 billion people in 106 countries are at risk of malaria.World Health Organizatio''World Malaria Report 2010''./ref> In 2012, malaria caused an estimated 627,000 deaths, mostly among African children. Asia, Latin America, and to a lesser extent the Middle East and parts of Europe are also affected. World Malaria Day sprang out of the efforts taking place across the African continent to commemorate Africa Malaria Day. WMD is one of 11 official global public health campaigns currently marked by the World Health Organization (WHO), along with World Health Day, World Blood Donor Day, World Immunization Week, World Antimicrobial Awareness Week, World Patient Safety Day, World Tuberculosis Day, World Chagas Disease Day, World No Tobacco Day, World Hepatitis Day and World AIDS Day.
