Tretinoin
Tretinoin is the acid form of vitamin A. It is also known as all trans retinoic acid, or ATRA. As a drug, it can be used used for the treatment of acne vulgaris and keratosis pilaris. The medicine goes under several brand names.
Thunder Bridge
Thunder Bridge is a hamlet near the villages of Stocksmoor and Kirkburton, in the Kirklees district, in the county of West Yorkshire, England. Thunder Bridge is also near the A629 road. The bridge is Grade 2 listed.
RuBisCO
Ribulose-1,5-bisphosphate carboxylase oxygenase, better known as RuBisCO, is an enzyme that catalyzes the first major step of carbon fixation in the Calvin cycle. Carbon fixation is a process by which the atoms of atmospheric carbon dioxide are made available to organisms in the form of energy-rich molecules such as glucose. RuBisCO splits 6-C molecules into two equal parts.
RuBisCO is very important in biology and ecology because it catalyzes the primary chemical reaction by which inorganic carbon permanently enters the biosphere.
RuBisCO is also the most abundant protein in leaves and the most abundant protein on Earth. It accounts for 50% of soluble leaf protein (20-30% of total leaf nitrogen) and 30% of soluble leaf protein in plants (5-9% of total leaf nitrogen).
Given its important role in the biosphere, there are currently efforts to genetically engineer crop plants to contain more efficient RuBisCO.
Boyle's law
Boyle's law (also called Mariotte's law and the Boyle-Mariotte law) is a law about ideal gases.
The law can be stated as follows:
In other words, the volume of a constant mass of ideal gas at a constant temperature is inversely proportional to the pressure applied on it.
In symbols, the law is:
or
where "P" is the pressure of the gas, "V" is the volume of the gas, and "k" is a constant.
For a given mass of gas at a constant temperature, the product of the pressure and the volume is constant. As the volume decreases, the pressure increases in proportion, and vice versa. For example, when the pressure halves, the volume doubles.
Suppose you have a tank that contains a certain volume of gas at a certain pressure. When you decrease the volume of the tank, the same number of gas particles is now contained in a smaller space. Therefore, the number of collisions increases. Therefore, the pressure is greater.
Imagine you have a gas at a certain pressure (P) and volume (V). If you change the pressure to a new value (P), the volume changes to a new value (V). We can use Boyle's law to describe both sets of conditions:
The constant, k, is the same in both cases, so we can say the following:
Example: The pressure of a gas is 3 atm and the volume is 5 litres. If the pressure is reduced to 2 atm, what is the volume?
∴ The volume will be 7.5 litres.
The law was found by Robert Boyle in 1662, and afterwards independently by Edme Mariotte in 1679.
Dik Trom
Dik Trom is the main character in a series of five children’s books written in the Dutch language. The author, C.Joh. Kieviet wrote the first book in 1891. It was called “Uit het leven van Dik Trom” (“From the life of Dik Trom”). The books became extremely popular and they continue to be very popular today, more than 100 years after they were written.
Dik Trom was a naughty boy who got up to lots of tricks with his friends. However, he is a very honest boy and he is very kind, so the readers like him.
Dik Trom lived in the village of Hoofddorp in the Harlemmermeer in the north of Holland. This is the village where the author grew up, so he was setting the stories in his own village, and based a lot of the characters on real people he had known.
Dik’s real name was “Dirk”. This is a common Dutch name. Dirk was very fat, even as a boy, so he soon became known as “Dik” (the Dutch word “dik” means “fat”). The word “trom” means “drum” so his name really means “Fat Drum”.
Dik’s parents love him very much, but they are no good at disciplining him. When he does something naughty his father just says: “‘t is toch een bijzonder kind - dat is-ie” (“he’s a really special child, that he is”).
Dik is always brave, he is never a coward. His friends want to go and annoy a little old lady, but Dik persuades them to go and annoy the village policeman, and he has a leading role in that adventure.
Another adventure tells how Dik said he could ride a donkey without falling off. The donkey belonged to the village merchant, and it was a stubborn beast that always tried to throw off its riders. Dik managed to stay on by sitting backwards on the donkey and holding on to its tail. This is how Dik is usually seen in pictures, and there is a statue of him in the village of Hoofddorp which shows him on the donkey.
Kieviet found it difficult at first to find a publisher for his book, because the main character was naughty. Once it had appeared in a second edition with some illustrations it became very popular, and Kieviet followed it with four other books about Dik, and one about Dik’s son. Eight films have been made about Dik Trom, the most recent in 2010.
Uranium-235
Uranium-235 is a radioactive isotope of uranium. Uranium-235 has 143 neutrons, 92 protons, and an isotope mass of 235.0439299. Uranium-235 has Pa, Np, and Pu as its parent isotopes. As it decays, it produces Th. Uranium-235 has a half-life of 703.8 million years. Uranium-235 makes up about 0.72% of natural uranium. When it is separated from the other uranium isotopes, it is called enriched uranium.
Enriched uranium is best known for its use in the bombing of Hiroshima on August 6, 1945. The bomb called Little Boy used Uranium-235. Uranium-235 can be used for nuclear fission. This fission is about 504.81 barns for slow thermal neutrons and 1 barn for fast thermal neutrons. Uranium-235 was discovered in 1935 by Arthur Jeffrey Dempster.
