It is made by reacting cadmium with hydrogen fluoride, hydrofluoric acid, or fluorine.
Cadmium fluoride is used in organic chemistry, as well as in medicine for fluoride treatment.
Cadmium iodide
Cadmium iodide is a chemical compound. Its chemical formula is CdI. It has cadmium and iodide ions in it.
Cadmium iodide is a white or pale yellow solid. It is known for its crystal structure. Many other chemical compounds have a cadmium iodide crystal structure. It easily dissolves in water. It is toxic.
It is made by reacting cadmium with iodine. It can also be made by reacting cadmium, or cadmium oxide with hydriodic acid.
Cadmium iodide is used to make phosphors (things that light when struck by UV light), photography, and electroplating.
Cadmium sulfide
Cadmium sulfide is a chemical compound. Its chemical formula is CdS. It has cadmium and sulfide ions in it.
Cadmium sulfide is a yellow orange solid. It does not dissolve in water. It reacts with hydrochloric acid to make hydrogen sulfide and cadmium chloride. It is used in an odd reaction where cadmium sulfide is sprinkled into a sulfide solution and light is shined on it. It starts making small amounts of hydrogen gas.
Cadmium sulfide is only found in two rare minerals. It is normally made artificially.
Cadmium sulfide is made several different ways. Cadmium salts, normally the sulfate or the chloride (cadmium chloride), are reacted with hydrogen sulfide to make a bright yellow cadmium sulfide solid. When it is made for pigment, the cadmium sulfide is then washed, heated (to change it into the right form), and ground to a powder. It is then mixed with paint.
Cadmium sulfide is used as a yellow pigment. Cadmium yellow is the name of the pigment. If selenide is added during the roasting process (seen above in "preparation" section), it can make an orange or a yellow pigment. Cadmium sulfide is a good pigment because it does not break down easily, is very bright, and does not react with air like other pigments can. It is toxic, though.
It is also used in photoresistors that are sensitive to infrared and red light. Cadmium sulfide is found around some bacteria that reduce sulfate to sulfide.
Kim Yu-sin
Kim Yu-Sin (김유신, 金庾信, 595 – July 673) was a general and politician of the Silla Kingdom in ancient Korea. He belonged to the royal family of Gaya, and served as a soldier of Silla. He conquered the kingdoms of Goguryeo and Baekje. After his death, he was given the title of Heungmu the Great (흥무대왕).
One Sweet Day
"One Sweet Day" is a song by American singer Mariah Carey. It is a duet with American boy-group Boyz II Men. The song was written by Mariah Carey, Walter Afanasieff and the members of Boyz II Men. "One Sweet Day" was produced by Carey and Afanasieff for her sixth album "Daydream". It was released as the album's second single in late 1995. The song speaks about losing a loved one, and one day seeing them in heaven once again. Both Carey and Boyz II Men wrote the song about specific people in their lives. "One Sweet Day" was positively reviewed by music critcs. The song became a hit in many countries around the world, especially in the United States. It spent sixteen weeks at number one on the "Billboard" Hot 100. It also became number one in Canada and New Zealand, and reached the top-ten in Australia, Belgium, France, Ireland, The Netherlands, Norway, Sweden and the United Kingdom. The music video for "One Sweet Day" featured clips of Carey and Boyz II Men in the studio recording the song.
Confuciusornis
Confuciusornis is a genus of primitive crow-sized birds from the Lower Cretaceous. It was found in the Yixian and Jiufotang Formations of China, dating from 125 to 120 million years ago. The bird was named after the Chinese moral philosopher Confucius (551–479 BC).
Like modern birds, "Confuciusornis" had a toothless beak, but close relatives of modern birds such as "Hesperornis" and "Ichthyornis" were toothed. This shows that the loss of teeth occurred more than once, in "Confuciusornis" and in ancestors of modern birds. This is an example of convergent evolution.
"Confuciusornis" is the oldest known bird to have a beak. It is also the first known bird to have lost the long tail of "Archaeopteryx" and develop fused tail vertebrae (a pygostyle).
"Confuciusornis" is one of the most abundant vertebrates found in the Yixian Formation, and "several hundred" complete, articulated specimens have been found.
The proportions of the toes suggest that they were used for both walking and perching, while the large claws of the thumb and third finger were probably used for climbing. The head probably had a small crest or tuft.
The orientation of the shoulder joint was sideways, instead of angled upward as in modern birds; this means that "Confuciusornis" was unable to lift its wings above its back. Like "Archaeopteryx", it was thus incapable of the upstroke required for flapping flight. This conclusion is not established at present. Peters sees "Confuciusornis" as capable of flapping flight but specialising in soaring flight. The bird's weight has also been debated.
An argument from Gregory Paul noted that "Confuciusornis" is commonly found as large groups in lake bottom sediments with little to no evidence of the bodies being moved after death. It would be highly unusual for gliding animals to be found in such large numbers in deep water. Rather, this evidence suggests that "Confuciusornis" traveled in large flocks over the lake surfaces, a habitat consistent with a flying animal.
In early 2010, a group of scientists led by Zhang Fucheng examined fossils with preserved melanosomes (organelles which contain colour pigments). By studying the fossils with an electron microscope, they found melanosomes preserved in a fossil "Confuciusornis" specimen.
The melanosomes where of two types, which indicates that "Confuciusornis" had hues of grey, red/brown and black, possibly something like the modern zebra finch.
Diplocaulus
Diplocaulus (meaning "double stalk") was an early amphibian, now extinct. It had a boomerang-shaped head formed by two long bones at the back of the head. It had four short legs, and a short, flattened tail. It was about 3 feet (1 m) long.
The Communist Manifesto
The Manifesto of the Communist Party (German: "Manifest der Kommunistischen Partei"), more commonly known as The Communist Manifesto, is a short book. It was written by the German Marxist political theorists Karl Marx and Friedrich Engels in 1848. The book was originally written in the German language. Since it was first published, it became one of the world's most influential and controversial political manuscripts, and has been translated into many languages. The book is about analyzing approaches to class struggles (from both the past and present), and problems with capitalism.
The book does not talk about or predict how communism would be in the future. It is a mixture of both Marx and Engels' theories and opinions on society and politics. It also has their written ideas of how the capitalist society of their time would be replaced by dictatorship of the proletariat, and after that, communism. Especially by the abolition of private property and child labour and by making means of production common, strong progressive income tax and free education for all.
The manuscript of the book is registered in the Memory of the World Programme together with the volume I of "The Capital" by Karl Marx in June 2013.
Werner Sombart
Werner Sombart (January 19, 1863–May 18, 1941) was a German economist and sociologist and was an important social scientist to Europe during the early 20th century.
Sombart was born in Ermsleben, Harz. He was the son of Anton Ludwig Sombart, a rich liberal politician, industrialist.
Werner studied at the universities in Pisa, Berlin, and Rome, learning both law and economics. In 1888, he received his Ph.D. from Berlin.
