Orange is a city in New South Wales, Australia. It is on the Mitchell Highway about 250 kilometres west of Sydney. The main street (where people do all the shopping) is quite large for a country town. There are five high schools and five primary schools in Orange. Orange has two tennis centres, a big pool, an indoor sports centre, a netball centre, football pitches, a university, hockey pitches and lots of parks. There is also a big mine called Cadia and a big fun lake located outside of the town.
Endometrium
The endometrium is the innermost membrane of the uterus. It sensitive to hormone changes. The endometrium is shed each month as menstrual flow.
Nibelungenlied
The Nibelungenlied, translated as The Song of the Nibelungs, is an epic poem in Middle High German. It tells the story of dragon-slayer Siegfried at the court of the Burgundians, and of the revenge of his wife Kriemhild, which leads to the death all the heroes of the Bugundians and of Kriemhild as well.
The saga of Siegfried was also used in the opera cycle "Der Ring des Nibelungen" of Richard Wagner. Nibelung in this context means "dwarf".
The Nibelungenlied is based on earlier works. It was part of oral tradition, meaning it usually was not written down. During the Middle Ages people started to write down stories more and more. Overall there are about 35 German sources and one Dutch source for the story. There was an original manuscript but it has been lost. The three oldest manuscripts have been labelled "A", "B", and "C".
"B" seems to be closest to the original; however, the real relation between the three manuscripts is unknown. The Nibelungenlied probably had a broad oral tradition, as there were many different versions. It is difficult to judge how these oral versions influenced the written ones.
Manuscripts A and B end with "daz ist der Nibelunge not" (that is the fall of the "Nibelungs"); for this reasons, they are known as the "Not versions". Manuscript C ends with "daz ist der Nibelunge liet" (). It is known as the "Lied-version". In total, the C text has been edited with regard to the public of the time. It is less dramatic. This probably made it more popular. Aesthetically, the B text would have been the greatest artistic achievement for a contemporary public.
The author who wrote down the original that is now lost is unknown. However, there are a few candidates:
Serious researchers tend to ignore the last three options, because there is not enough evidence to support them.
This was probably not in the original though, but added later. The original probably began by introducing Kriemhild:
English translations:
Dwarf (mythology)
A dwarf is a short, humanlike creature from Norse and Germanic mythologies. They have been used in many fairy tales, fantasy, fiction and role-playing games.
In some stories, dwarves are mean, living under bridges, and having a bad reputation for stealing treasure. One example is the Norwegian Troll. It is an ugly and foolish creature who tells lies. It causes problems everywhere it goes. That is how the Internet troll got its name. In Robert Louis Stevenson's story, "Strange Case of Dr. Jekyll and Mr. Hyde," Edward Hyde is described as "a dwarf."
On the other hand, J. R. R. Tolkien's hobbits and the munchkins in The Wizard of Oz are likeable, honest, good and smart.
Vanir
The Vanir are one of the two tribes of deities in Norse mythology, the other being the Æsir. Native to Vanaheimr, the Vanir are peace-loving gods, associated with nature and fertility, while the Æsir were chaotic and warlike. Members of the Vanir include:
A number of them live in Asgard alongside the Æsir as a token of goodwill following the war between the two tribes, which resulted in them uniting into a single pantheon. The goddess Freyja receives half of those slain in battle as a share of power between the two clans.
Mole (unit)
Mole is the SI unit used to measure how many molecules or atoms there are. One mole is around 600 sextillion molecules. Scientists use this number because 1 gram of hydrogen is around 1 mole of atoms.
The exact value of one mole is . This number comes from experiments with carbon because it's easy to work with.
Anything can be measured in moles, but it is not practical for most tasks because the value is so massive. For example, one mole of grapefruits would be as big as the earth.
Because different molecules and atoms do not have the same mass, one mole of one thing does not weigh the same as one mole of something else. Atoms and molecule mass is measured in amu. One amu is equal to one gram per mole. This means that if an atom has a mass of one amu, one mole of this atom weighs one gram.
Moles = mass (g) / Relative mass (grams per mole)
Example: How many moles are there in 20 grams of hydrogen?
A value of 1 can be used for hydrogen's relative mass, although the correct value is slightly larger. So: moles = mass/relative mass = 20/1 = 20 moles.
Moles = concentration (mol/dm) x volume (dm)
Example: How many moles are there in 100cm of 0.1M HSO?
1 dm is the same as 1000 cm, so the value in cubic centimetres needs to be divided by 1000. 100/1000 x 0.1 = 0.01 moles.
A methane molecule is made from one carbon atom and four hydrogen atoms. Carbon has a mass of 12.011 u and hydrogen has a mass of 1.008 u. This means that the mass of one methane molecule is 12.011 u + (4 × 1.008u), or 16.043 u. This means that one mole of methane has a mass of 16.043 grams.
A mole can be thought of as two bags of different sized balls. One bag contains 3 tennis balls and the other 3 footballs. There is the same number of balls in both bags but the mass of the footballs is much larger. It is a different way to measure things. Moles measure the number of particles, not the mass. So both bags contain three moles.
A mole is simply a unit of the number of things. Other common units include a dozen, meaning  12, and a score, meaning 20. Similarly, a mole refers to a specific quantity-- its distinguishing feature is that its number is far larger than other common units. Such units are typically invented when existing units can not describe something easily enough. Chemical reactions typically take place between molecules of varying weights, meaning measurements of mass (such as grams) can be misleading when compared the reactions of individual molecules. On the other hand, using the absolute number of atoms/molecules/ions would also be confusing, as the massive numbers involved would make it all too easy to misplace a value or drop a digit. As such, working in moles allows scientists to refer to a specific quantity of molecules or atoms without resorting to excessively large numbers.
The SI units for molar concentration are mol/m. However, most chemical writing uses mol/dm, or mol dm, which is the same as mol/L. These units are often written with a capital letter M (pronounced "molar"), sometimes preceded by an SI prefix, for example, millimoles per litre (mmol/L) or millimolar (mM), micromoles/litre (µmol/L) or micromolar (µM), or nanomoles/L (nmol/L) or nanomolar (nM).
The absolute yield of a chemical reaction mostly stated in moles (called the "molar yield").
Plesiosaurus
Plesiosaurus was a large fossil marine reptile, a genus in the order Plesiosauria.
The first specimen discovered by Mary Anning in 1820-21 was missing its skull. She found it on the 'Jurassic Coast' of Lyme Regis, Dorset, England. In 1823 she found another one, this time complete with its skull. The name "Plesiosaurus" was given by the Rev. William Conybeare.
"Plesiosaurus" was a predator, living mostly on fish and belemnites. It would swim through schools of fish and use its long neck and sharp teeth to snap them up.
