Gestation
In humans, birth normally occurs at a gestational age of about 40 weeks, though it is common for births to occur from 37 to 42 weeks. After 8 weeks, the embryo is called a fetus.
Leptospirosis
It is estimated that seven to ten million people are infected by leptospirosis annually. One million cases of severe leptospirosis occur annually, with 58,900 deaths. Leptospirosis is found in both urban and rural areas in tropical, subtropical, and temperate regions. The risk of death is 5 to 10%.Annual rates of infection vary from 0.1 to 1 per 100,000 in temperate climates to 10 to 100 per 100,000 in tropical climates. This leads to a lower number of registered cases than likely exists. The highest estimates of disease morbidity and mortality were observed in South and Southeast Asia, Oceania, Caribbean, Latin America and Africa. Antarctica is the only place not affected by leptospirosis. In the United States, there were 100 to 150 leptospirosis cases annually. In 1994, leptospirosis ceased to be a notifiable disease in the United States except in 36 territories where leptospirosis are prevalent such as Hawaii, Texas, California, and Puerto Rico. About 50% of the cases occurred in Puerto Rico. In January 2013, leptosprirosis was reinstated as a nationally notifiable disease in the United States. Between 1995 and 2005,  a single successful clone of L. interrogans caused a sustained leptospirosis outbreak in Thailand.The number of new cases of leptospirosis is difficult to estimate since many cases are not reported. There are many reasons for this, but the biggest issue is differentiating the disease from other conditions with a similar presentation. Laboratory testing is lacking in many areas. The global incidence of leptospirosis has been underestimated because most affected countries lack notification or notification is not mandatory.
Armenia
The Ottoman Empire began to collapse, and in 1908, the Young Turk Revolution overthrew the government of Sultan Hamid. In April 1909, the Adana massacre occurred in the Adana Vilayet of the Ottoman Empire resulting in the deaths of as many as 20,000–30,000 Armenians. The Armenians living in the empire hoped that the Committee of Union and Progress would change their second-class status. Armenian reform package (1914) was presented as a solution by appointing an inspector general over Armenian issues.
Cobalt(II) chloride
Cobalt (II) chloride is an inorganic compound of cobalt and chlorine, with the formula CoCl. It is usually supplied as the hexahydrate CoCl 6H O, which is one of the most commonly used cobalt compounds in the lab.
Liberia
Hospitals in Liberia include the John F. Kennedy Medical Center in Monrovia and several others. Life expectancy in Liberia is estimated to be 57.4 years in 2012. With a fertility rate of 5.9 births per woman, the maternal mortality rate stood at 990 per 100,000 births in 2010. A number of highly communicable diseases are widespread, including tuberculosis, diarrheal diseases and malaria. In 2007, the HIV infection rates stood at 2% of the population aged 15–49  whereas the incidence of tuberculosis was 420 per 100,000 people in 2008. Approximately 58.2% – 66% of women are estimated to have undergone female genital mutilation.
Knights of Sidonia
The story follows the adventures of Garde pilot Nagate Tanikaze, who lived in the underground layer of Sidonia since birth and was raised by his grandfather. Never having met anyone else, he trains himself in an old Guardian pilot simulator every day, eventually mastering it. After his grandfather's death, he emerges to the surface and is selected as a Guardian pilot, just as Sidonia is once again threatened by the Gauna.
United Copper
The United Copper Company was a short-lived United States copper mining business in the early 20th century that played a pivotal role in the Panic of 1907.
Child labour
In 2008, Bloomberg claimed child labour in copper and cobalt mines that supplied Chinese companies in Congo. The children are creuseurs, that is they dig the ore by hand, carry sacks of ores on their backs, and these are then purchased by these companies. Over 60 of Katanga's 75 processing plants are owned by Chinese companies and 90 percent of the region's minerals go to China. An African NGO report claimed 80,000 child labourers under the age of 15, or about 40% of all miners, were supplying ore to Chinese companies in this African region. Amnesty International alleged in 2016 that some cobalt sold by Congo Dongfang Mining was produced by child labor, and that it was being used in lithium-ion batteries powering electric cars and mobile devices worldwide.
Mali
In 2007, about 48 percent of Malians were younger than 12 years old, 49 percent were 15–64 years old, and 3 percent were 65 and older. The median age was 15.9 years. The birth rate in 2014 is 45.53 births per 1,000, and the total fertility rate (in 2012) was 6.4 children per woman. The death rate in 2007 was 16.5 deaths per 1,000. Life expectancy at birth was 53.06 years total (51.43 for males and 54.73 for females). Mali has one of the world's highest rates of infant mortality, with 106 deaths per 1,000 live births in 2007.
Bern
Bern has a population of 140,634 people and 34% of the population are resident foreign nationals. Over the 10 years between 2000 and 2010, the population changed at a rate of 0.6%. Migration accounted for 1.3%, while births and deaths accounted for −2.1%.
Nanjing
According to the Sixth China Census, the total population of the City of Nanjing reached 8.005 million in 2010. The statistics in 2011 estimated the total population to be 8.11 million. The birth rate was 8.86 percent and the death rate was 6.88 percent. The urban area had a population of 6.47 million people. The sex ratio of the city population was 107.31 males to 100 females.
Copper
There are 29 isotopes of copper. 63Cu and 65Cu are stable, with 63Cu comprising approximately 69% of naturally occurring copper; they both have a spin of 3⁄2. The other isotopes are radioactive, with the most stable being 67Cu with a half-life of 61.83 hours. Seven metastable isotopes have been characterized, with 68mCu the longest-lived with a half-life of 3.8 minutes. Isotopes with a mass number above 64 decay by β−, whereas those with a mass number below 64 decay by β+. 64Cu, which has a half-life of 12.7 hours, decays both ways.
2008 Sichuan earthquake
The 2008 Sichuan earthquake or the Great Sichuan earthquake, measured at 8.0 Ms and 7.9 Mw, and occurred at 02:28:01 PM China Standard Time at epicenter (06:28:01 UTC) on May 12 in Sichuan province, killed 69,197 people and left 18,222 missing.
Copper
Britain's first use of brass occurred around the 3rd–2nd century BC. In North America, copper mining began with marginal workings by Native Americans. Native copper is known to have been extracted from sites on Isle Royale with primitive stone tools between 800 and 1600. Copper metallurgy was flourishing in South America, particularly in Peru around 1000 AD; it proceeded at a much slower rate on other continents. Copper burial ornamentals from the 15th century have been uncovered, but the metal's commercial production did not start until the early 20th century.
Republic of the Congo
As of 2010, the maternal mortality rate was 560 deaths/100,000 live births, and the infant mortality rate was 59.34 deaths/1,000 live births. Female genital mutilation (FGM) is rare in the country, being confined to limited geographic areas of the country.
History of Chinese currency
Late Imperial China maintained both a silver and a copper currency system. The copper system was based on the copper cash (wen). The silver system had several units which by the Qing Dynasty were: 1 tael = 10 mace = 100 candareens = 1000 lí (silver cash).
Philadelphia
During the last decade, Philadelphia experienced a large shift in its age profile. In 2000, the city's population pyramid had a largely stationary shape. In 2013, the city took on an expansive pyramid shape, with an increase in the three millennial age groups, 20 to 24, 25 to 29, and 30 to 34. The city's 25- to 29-year-old age group was the city's largest age cohort. According to the 2010 Census, 343,837 (22.5%) were under the age of 18; 203,697 (13.3%) from 18 to 25; 434,385 (28.5%) from 25 to 44; 358,778 (23.5%) from 45 to 64; and 185,309 (12.1%) who were 65 years of age or older. The median age was 33.5 years. For every 100 females there were 89.4 males. For every 100 females age 18 and over, there were 85.7 males. The city had 22,018 births in 2013, down from a peak 23,689 births in 2008. Philadelphia's death rate was at its lowest in at least a half-century, 13,691 deaths in 2013. Another factor attributing to the population increase is Philadelphia's immigration rate. In 2013, 12.7 percent of residents were foreign-born, just shy of the national average, 13.1 percent.
Copper
Copper is synthesized in massive stars and is present in the Earth's crust at a concentration of about 50 parts per million (ppm), where it occurs as native copper or in minerals such as the copper sulfides chalcopyrite and chalcocite, the copper carbonates azurite and malachite, and the copper(I) oxide mineral cuprite. The largest mass of elemental copper discovered weighed 420 tonnes and was found in 1857 on the Keweenaw Peninsula in Michigan, US. Native copper is a polycrystal, with the largest described single crystal measuring 4.4×3.2×3.2 cm.
Countries of the United Kingdom by population
The population of the countries and regions of the United Kingdom was last measured by census in 2011. and the Census organisations have produced population estimates for subsequent years by updating the census results with estimates of births, deaths and migration in each year. The census results, and the annual population estimates, summarised below show that England is by far the most populous country of the United Kingdom and its population is therefore also presented by region.
Webbed toes
Webbed toes is the common name for syndactyly affecting the feet. It is characterised by the fusion of two or more digits of the feet. This is normal in many birds, such as ducks; amphibians, such as frogs; and mammals, such as kangaroos. In humans it is considered unusual, occurring in approximately one in 2,000 to 2,500 live births.
