People with hepatitis A should rest, drink a lot of water and avoid alcohol. The time between the infection and the start of the illness can run from 15 to 45 days. About 15% of people with hepatitis A have symptoms from six months to a year after the first diagnosis. Infected people excrete the hepatitis A virus in their stool two weeks before and one week after the appearance of jaundice.
There is a vaccine for hepatitis A. It will protect against hepatitis A for life.
Hepatitis B is not spread by food or casual contact. Instead, hepatitis B is spread by blood or body fluids from an infected person. A baby can get it from its mother during childbirth, and it can also be spread by sexual contact, use of street drugs, and unsafe medical care. Some people just have hepatitis B for a little while and then suppress the infection. Others can be infected for life, usually with few or no symptoms for many years. Hepatitis B sometimes damages the liver severely, and can cause cancer.
There is a vaccine that can prevent hepatitis B. There is no cure for hepatitis B, but there is treatment.
Hepatitis C is not spread by food or casual contact. It is spread in ways that are similar to hepatitis B. There is no vaccine, and the treatment is somewhat unpleasant. People with hepatitis C who drink alcohol greatly increase their risk for liver damage.
Rodeo
A rodeo is a North American sport. It is a collection of several similar activities that came from the history of the day-to-day lives of Mexican vaqueros (cowboys) and American cowboys. It has events that came from the handling of cattle, and the riding and training of horses. Rodeos started as a competition between the cowboys to see who was the best. Over time it has gone from taking a collection of money for the person who won to today's large professional competitions such as the National Finals Rodeo with a lot of money for the winners.
Dewey Decimal System
The Dewey Decimal System is a way to put books in order by subject. It is often used in public libraries and schools in the United States and other countries. It places the books on the shelf by subject using numbers from 000 to 999. It is called "decimal" because it uses numbers to the right of the decimal point for more detail (e.g. 944.1 for History of Brittany). Each subject has its own group of numbers. The system was created by Melvil Dewey in 1876. It is also called the Dewey Decimal Classification. The classification has been changed many times. The latest change is number 23 in 2011. There is also a smaller one for small libraries called "Abridged Dewey".
Each subject is broken up into 10 smaller, more specific categories.
Here is a list of some sections in it:
Rhombus
A rhombus is a parallelogram with all sides equal in length. A rhombus with all angles equal is called a square. The word "rhombus" comes from the Greek word "rhombos", meaning "spinning top". A rhombus is sometimes called a diamond, but not all rhombi are diamond shaped.
To find the perimeter of a rhombus, just add up all the sides. Also opposite sides are parallel and opposite angles are equal. Another interesting thing is that the diagonals (dashed lines in second figure) meet in the middle at a right angle.
Change (money)
"Change"' is the money returned after paying for something with more money than it costs. For example, if someone buys a 25-pence sweet bar with 1 pound (100 pence), they will get 75 pence back.
Change can also mean any kind of money in coin form. To have "exact change" means to have the exact cost of the item. In the United States, buses require people riding the bus to have "exact change". The bus does not give money back. They must pay exactly what the cost is, they can not pay more.
Homework
Homework is work that is given by teachers for students to do at home. Homework is usually given to students by their school teachers. It is a practice work which helps students revise what they've learned that day.
Homework helps students to remember what they learned. Some students will get more homework and some will get less. This depends on how old they are, what grade/primary/year they are in and how smart/intelligent they are. This could help decide what level they are at.
Some students say that homework is a waste of time and that they do enough work at school. However, it is often believed that homework is important for a student because it may help in their exams and education. Homework is essential for anyone that is confused or behind a subject.
Homework helps parents to get to know about their children progress in studies. It can also teach a child to be responsible. However, it has sometimes been a controversial form of learning as some groups argue about its disadvantages.
Garlic
Garlic (species Allium sativum) is a type of plant that people eat for food. Garlic is related to onions, shallots, and leeks. It has a very strong flavor and smell. Most of the time, people use it as a flavoring so that it helps make food taste better.
Garlic is used as herbal medicine in the treatment of cold and flu. It has side effects of heartburn, flatulence and sweating.
The part of the garlic plant that people eat is called the head. It grows at the bottom of a long green stalk. People pull the head apart into smaller pieces called cloves of garlic. Cloves have papery skin on them. People peel off the skin before cooking the cloves.
People plant garlic in the fall right after the first frost. They plant the clove like a seed. One clove can grow into a whole head. The garlic plant grows its roots before the ground freezes for winter. People harvest (collect) the garlic in the middle of the next summer.
Garlic is in legends about vampires. In these legends, vampires do not like garlic. Garlic keeps vampires away. Writers for the Toronto Garlic Festival say this might be because the vampire legend comes from the disease porphyria. People with porphyria do not like to eat foods that have sulfur in them, like garlic.
Glaze
Glaze is a layer or coating used on pottery or ceramics. It may be called vitreous enamel or porcelain enamel. Powdered glass is fused onto ceramics by firing to between 750 and 850 °C (1,380 and 1,560 °F). The powder melts, flows, and then hardens to a smooth, lasting vitreous coating on metal, or on glass or ceramics. This is done in a kiln.
There are many different types of glaze, some are used for decoration and some are used to make pottery watertight so it can hold liquids. Glaze serves to colour, decorate, strengthen or waterproof an item.
Glazing is important for earthenware vessels as otherwise they would leak water. Glaze is also used on stoneware and porcelain. In addition to the functional aspect of glazes, they can form a variety of surface finishes, including degrees of gloss and matte and colour. Glazes may also enhance an underlying design or texture.
Glaze is used on building materials. The Iron Pagoda, built in 1049 in Kaifeng, China, of glazed bricks is an example.
Ceramic glaze raw materials generally include silica, which forms glass when fired. Metal oxides, such as sodium, potassium and calcium, act as a "flux" to lower the melting temperature. Alumina, often derived from clay, stiffens the molten glaze to prevent it from running off the piece. Colour comes from iron oxide, copper carbonate or cobalt carbonate. Tin oxide or zirconium oxide make the glaze opaque.

Nuclear means relating to a nucleus. It may be about:

Stanford University
The Leland Stanford Junior University, often called Stanford University (or simply Stanford), is a private university next to Palo Alto in California, in the middle of Silicon Valley,
about 37 miles (60 kilometers) southeast of San Francisco and about 20 miles northwest of San José, in Santa Clara County. Leland and Jane Stanford opened the university on 1 October 1891. They named the university after their son, Leland Stanford Junior, who died at young age.
