Victor Babeş discovered more than 50 germs and a cure for a disease named after him, babesiosis; biologist Nicolae Paulescu discovered insulin. Another biologist, Emil Palade, received the Nobel Prize for his contributions to cell biology. George Constantinescu created the theory of sonics, while Lazăr Edeleanu was the first chemist to synthesize amphetamine and also invented the modern method of refining crude oil. Costin Neniţescu found new methods for the synthesis of pirilium salts, of carbenes, tryptamine, serotonin, two new syntheses for the indole nucleus, and a new method of polymerisation of ethylene.
Several mathematicians distinguished themselves as well, among them: Gheorghe Ţiţeica, Spiru Haret, Grigore Moisil, Miron Nicolescu, Nicolae Popescu and Ştefan Odobleja; the latter is also regarded as the ideological father behind cybernetics.
Notable physicists and inventors also include: Horia Hulubei in atomic physics, Șerban Țițeica in theoretical physics, Mihai Gavrilă specialized in quantum theory and discoverer of the atomic dichotomy phenomenon, Alexandru Proca (known for the first meson theory of nuclear forces and Proca's equations of the vectorial mesonic field), Ştefan Procopiu known for the first theory of the magnetic moment of the electron in 1911 (now known as the Bohr-Procopiu magneton), Theodor V. Ionescu, the inventor of a multiple-cavity magnetron (1935), a hydrogen maser in 1947, 3D imaging for cinema/television in 1924 and hot deuterium plasma studies for controlled nuclear fusion, Ionel Solomon known for the nuclear magnetic resonance theory in solids, Solomon equations and photovoltaic devices, Petrache Poenaru, Nicolae Teclu and Victor Toma, with the latter known for the invention and construction of the first Romanian computer, the CIFA-1 in 1955.
The nuclear physics facility of the European Union's proposed Extreme Light Infrastructure (ELI) laser will be built in Romania. Romania currently has 1,400 MW of nuclear power capacity by means of one active nuclear power plant (Cernavodă) with 2 reactors, which constitutes around 18% of the national power generation capacity of the country. This makes Romania the 23rd largest user of nuclear power in the world.
The Constitution of Romania is found to be based from the Constitution of France's Fifth Republic. It was passed into law on December 8, 1991. after a referendum was held. 73 amendments were added to the constitution in October of 2003 to bring the constitution of Romania up to code with the constitution of the European Union.
The legislative branch of the Romanian government is known as the Parliament. It contains two chambers – the Senate, containing 140 members, and the Chamber of Deputies, which has 346 members. The members of both chambers are elected every four years through party-list proportional representation.
The judicial branch of the Romanian government is separate from the other branches. It is made up of a system of courts. The court with the most authority is the High Court of Cassation and Justice, which is the supreme court of Romania. Other courts, including appeal, county, and local courts also make up the judicial branch of the Romanian Government. The way the system of courts works in Romania is modelled off of the French model of law. It is based on civil law.
Romania is divided into 41 counties, including the municipality of Bucharest, which is also its own county.
Romania is divided further into 319 cities and 2,686 communes. Each of the communes has its own council that is led by a mayor.
The Romanian Army is made up of Land, Air, and Naval Forces, which are all led by a Commander-in-chief. The commander-in-chief is given orders by the Ministry of Defense. During war, the President leads the Army. 90,000 people were in the Romanian Army in 2003: 15,000 civilians and 75,000 military people. Of the 75,000 military people in the Romanian Army, 45,800 are in the land forces, 13,250 are in the air forces, 6,800 are in the naval forces, and 8,800 in other areas of the military.
Argon
Argon is a chemical element. The symbol for argon is Ar, and its atomic number (or proton number) is 18. It is a noble gas and no electrons or protons can be lost or gained from this atom.
Argon atoms are found in air. About 1% of the Earth's atmosphere (the air around us) is argon.
Argon is often used when welding steel and similar work, to push away the air around the weld, so the oxygen in the air can't join with the metal being welded.
Trade
To trade is to willingly give things or services and get other things or services in return. For example, a person giving a thing must find another person who wants to get that thing. The giver gets something back in return. A trade is also called an exchange or a swap.
An early type of trade is barter. Barter was the exchange of goods and services for other goods and services. Barter involves trading things without using of money. Modern traders commonly buy and sell by the use of money. Trade between two traders is called bilateral trade. Trade between more than two traders is called multilateral trade.
The things that are given from one person to the other are called goods.
Services can also be part of a trade. One person can do a job or work for another, and get something in return in a trade.
Money can be given in return for a service or for a thing. If money is part of the trade, then the person who gives the money is buying, and the person who gets the money is selling.
A place where trading takes place is called a market.
When there is no money involved in the trade, the trade is called barter. If there is money involved in the trade, the trade is called a purchase. In the past people would barter to get what they wanted, instead of buying goods and services.
Economics includes the study of trade.
Trade occurs not just between people, but also between large companies and even countries. Governments sometimes take some of the money or goods involved trade between countries. This is a type of tax called a tariff. Smugglers try to trade without paying tariffs.
Free trade between two countries is when there are small or no tariffs, quotas, or other restrictions on trade.
There are two forms of trade. They are
Domestic trade is the exchange of goods within a country. Domestic trade is very important because it allows different types of goods to reach to all parts of the country. It makes the standard of living of the people of the country better. It helps an industry to grow by making sure that there are raw materials. Domestic trade may be divided into two. They are:
Wholeselling is the sale of goods to industrial, commercial, institutional or other professional businesses. They can also be sold to other wholesalers. It is the sale of goods to anyone that is not a consumer. Wholesalers usually buy and sort goods in large numbers.
Retail is the process of selling goods or services to consumers through many means of distribution to earn a profit. The term "retailer" usually means where a person sells a small amount of good to many individuals, who are consumers.
International trade is the exchange of goods and services between different countries. International trade has existed throughout history. For example Uttarapatha, Silk Road, Amber Road, scramble for Africa, Atlantic slave trade, salt roads. When there is trade between two or more countries factors like currency, government policies, economy, judicial system, laws, and markets affect trade.
International trade may be divided into three. They are:
An import is a good or service that was bought in one country but was produced in another country.
An export is a good or service that was produced in one country but was sold to another country.
An entrepôt is a port, city, or trading post where goods may be imported, stored or sold. These cities grew because of the growth of long-distance trade.
