There is a fossil record of two adults and a 12.2 meter (40 ft) long juvenile that died together in the late Jurassic leriod, about 150 million years ago (northeast Wyoming). It is assumed that their bodies were washed to their final resting place, in river mud. This suggests that "Camarasaurus" traveled in herds or, at least, 'family' groups. Also, recovered camarasaur eggs have been found in lines, rather than in neatly arranged nests as with some other dinosaurs, which appears to suggest that, like most sauropods, "Camarasaurus" did not tend its young.
Zizhongosaurus
Zizhongosaurus was a very large plant-eating dinosaur. It was a large sauropod, related to "Camarasaurus".
Burping
Burping is when gas comes out of the stomach through the mouth. Burping happens when air is trapped in the stomach. "Esophageal speech" means to "burp" words.
Great Fire of London
The Great Fire of London happened in Central London in 1666. The fire lasted for just under five days, from 2nd September until 6th September.
It is believed to have destroyed the homes of 70,000 of the 80,000 people that lived in the city. It is not known how many people died in the fire. Only a few deaths are certain, but for many of the victims there were no records. The fire may have cremated many, leaving no recognisable remains. It threatened the aristocratic district of Westminster (the modern West End), Charles II's Palace of Whitehall, and most of the suburban slums, however, it never reached these districts.
The fire started at the bakery of Thomas Farriner (or Farynor) on Pudding Lane. It began just after midnight on Sunday 2nd September and grew very fast. Firefighters of the time usually made firebreaks by destroying buildings around the fire so it could not spread. This did not happen quick enough. Lord Mayor, Sir Thomas Bloodworth was not certain what to do. By the time he ordered such measures, it was too late. The Tower of London guard used gunpowder to make good firebreaks that stopped the fire from spreading to the east.
The fire pushed north on Monday into the center of the city. Some people thought that foreigners were setting the fires. They believed it was the French and Dutch, who at that time were England's enemies in the Anglo-Dutch Wars. On Thursday, the fire spread over most of the City, destroying St. Paul's Cathedral and crossed over the River Fleet. It was close to setting fire to Charles II's court at Whitehall.
The social and economic problems created from this were very large. Leaving London to go and live elsewhere was strongly encouraged by Charles II. He feared a London rebellion amongst the refugees who had lost their property. Despite numerous radical proposals, London was reconstructed on essentially the same street plan used before the fire.
The fire is said to have also helped to get rid of the Great Plague which had hit London in 1665, and killed about 70,000 of the 90,000 population, who may have died in the fire. We are able to know a lot about the great fire of London because Samuel Pepys wrote in his famous diary at the time. When the fire started, he looked out of his window, saw the fire and started writing about it.
The damages have been calculated to 13,500 houses, 87 parish churches, 44 Company Halls, the Royal Exchange, the Custom House, St Paul's Cathedral, the Bridewell Palace and other City prisons, the General Letter Office, and the three western city gates—Ludgate, Newgate, and Aldersgate.
Golgi complex
The Golgi complex, also known as the Golgi apparatus or simply the Golgi, is a cytoplasmic organelle. It is found in eukaryote cells, as in animals, plants, and fungi.
The complex was discovered by Camillo Golgi in 1898. Golgi, who worked at Pavia, Italy, was ignored. His discovery was said to be dirt on his lenses. Years later, electron microscope pictures showed structures just like in the original Golgi drawings. It is made of several flattened sac-like membranes which look like a stack of pancakes.
The main function of the Golgi apparatus is to process and package macromolecules, such as proteins and lipids. They come to the Golgi after being built, and before they go to their destination. Much of the enzymatic processing is post-translational modification of proteins. The Golgi complex inspects them for flaws and discards extra material added during their manufacture, wraps them up and then targets them for packaging. The Golgi complex is especially active in processing proteins for secretion. The Golgi releases special enzymes called lysosomes, which clean off any extra amino acids. When the package is ready, it is pinched off the Golgi and released into the cytoplasm.
The Golgi complex is part of the cellular membrane system, and so is the endoplasmic reticulum.
Institut Teknologi Bandung
Institut Teknologi Bandung (ITB) is a public government-funded, higher education, technology school located in Bandung, West Java, Indonesia. Institut Teknologi Bandung are the one of most popular university in Indonesia, together with Gadjah Mada University and University of Indonesia. The symbol of Institut Teknologi Bandung is Ganesha, a Hindu god representing wisdom.
Superconductor
A superconductor is a substance that conducts electricity without resistance when it becomes colder than a "critical temperature." At this temperature, electrons can move freely through the material. Superconductors are different from ordinary conductors, even very good ones. Ordinary conductors lose their resistance slowly as they get colder. In contrast, superconductors lose their resistance all at once. This is an example of a phase transition. High magnetic fields destroy superconductivity and restore the normal conducting state.
Normally, a magnet moving by a conductor produces currents in the conductor by electromagnetic induction. But a superconductor actually pushes out magnetic fields entirely by inducing surface currents. Instead of letting the magnetic field pass through, the superconductor acts like a magnet pointing the opposite way, which repels the real magnet. This is called the Meissner effect, and it can be demonstrated by levitating a superconductor over magnets or vice versa.
Physicists explain superconductivity by describing what happens when temperatures get cold. The thermal energy in a solid or liquid shakes the atoms so they randomly vibrate, but this gets less as the temperature drops. Electrons carry the same negative electric charge which makes them repel each other. At higher temperatures each electron behaves as if it were a free particle. There is also however a very weak attraction between electrons when they are in a solid or liquid. At rather large distances ( many hundreds of nanometers apart) and low temperatures (near absolute zero), the attractive effect and lack of thermal energy allows pairs of electrons to hang together. This is called a cooper pair and it is a quasiparticle , that is it acts as if it were a new kind of particle in its own right even though it is made up of two fundamental electrons. Many overlapping cooper pairs can exist in the same nanometer sized space. Since paired electrons constitute a boson the motions of all of the cooper pairs within a single superconductor synchronise and they function as if they are a single entity. Small disturbances such as scattering of electrons are forbidden in this state and it moves as one showing no resistance to its motion. It is hence now a superconductor.
Alan Freeman
Alan Leslie "Fluff" Freeman (born 6 July 1927 in Melbourne, Victoria, Australia, died 27 November 2006 in London, England) was an Australian radio presenter who worked for most of his career in the United Kingdom.
In May 2000 he was presented with a Lifetime Achievement award at the Sony Radio Academy Awards.
Freeman was best known for presenting "Pick of the Pops" on BBC Radio 1 throughout the 1960s and 1970s.
Freeman was openly bisexual.
