In one sentence, describe what the following article is about: Keep the clay in a dry, well-ventilated area, and leave it undisturbed. Every 4-6 hours, check on the clay to look for cracks or chips, and make sure the clay is hardening. The drying time will vary based on the thickness of the clay and the moisture in the air, but most types of air dry clays will be completely dry within 72 hours. If your clay isn’t hardening after 12 hours or so, try increasing the temperature by blowing the clay with a hair dryer, or placing it in the oven on the lowest temperature for 1-2 hours. Check on the clay often. Adding color or a design to your clay is easy. Simply wait until the clay has dried, and use a paintbrush to apply acrylic or tempera paint. Then, let the paint dry for 24 hours, and protect the paint by using a spray-on or brush-on paint sealant all over the clay. If you’re making an intricate design on a clay pot, for example, make sure you use a thin, fine paintbrush, and seal the entire pot after the paint has dried.
Summary: Let the clay sit for 24-48 hours to dry. Wait to paint the clay until after it has dried.

Because pigeons are social animals, keeping a single one is only recommended if you're sure you can offer enough time and companionship to keep your pigeon happy.  You should also consult local regulations to verify that you are permitted to keep pigeons.  There are many different breeds of pigeons and their respective social needs vary considerably. However, you should be able to set aside some time every day to help socialize your pigeon. You should have indoor accommodations for your pigeon and, if at all possible, outside accommodations as well. It is important that you prepare these ahead of time. It will be disconcerting to the pigeon to relocate it without providing it with a new home immediately. Clean all cages before your pigeon arrives.  An ideal indoor cage is rectangular and partially enclosed. Be sure that there are no holes in the cage long enough for the pigeon to stick its head through. Because pigeons like to walk, the bottom of the cage should be covered with paper or grassy sod. Keep the cage in a bright area but not one with direct sunlight. If the cage is in a place liable to be exposed to light at night, you should cover the cage during the evening. An outdoor aviary should be approximately 6’ square and 8’ high. Include shelves for nesting, including one as high as possible in the enclosure.  The enclosure should be sturdy enough to protect against outside predators. If possible the aviary should be oriented toward the south or southwest, allowing for maximum sunlight.  include in the housing a bath that the bird can use to clean itself. Certain breeds are adapted to free flight. You can provide them with a “dovecote,” which is a small structure that can be attached to the side of your house. Be aware, however, that your bird could be hunted by predators if permitted to fly freely. There are a variety of mixes that are designed for pigeons and doves. Pelleted diets are the best source of nutrients. Seed diets and other commercial mixes will require more supplementation.  You can supplement the pigeons regular diet with lettuce, endive, chickweed, spinach, berries, apple, and pears. Providing the pigeon with grit and gravel will help it digest its food. Pet stores also sell vitamins and calcium supplements for birds that can help improve your pigeons health. Online you can find databases of local breeders.. Some locations also have issues with abandoned pigeons. That means you should be able find them at the local animal shelter. Either way, you should ask about the breed of pigeon and care specifications, because different breeds vary considerably in terms of needs and behavior. it is recommended that you meet a few pigeons beforehand to check for allergies, and make sure they meet your expectations. Judge whether or not the shelter is clean and the pigeons well cared for. If the pigeons are not well cared for, it might be difficult to socialize them.

Problem: Article: Low grade fever (37.2°C – 37.8°C or 99°F - 100°F) is a symptoms of Rubella. Fever is one of the body's defense mechanisms against infection, as the heat kills off microorganisms causing the disease.  When the body’s immune system senses foreign bodies, pyrogens (substances that cause fever) are released and travel to the hypothalamus (part of the brain which regulates body temperature). The pyrogens now bind to the receptors in the hypothalamus and the body’s temperature starts to rise, resulting in fever. When you are suffering from enlarged lymph nodes, the back of the neck, behind the ears and the base of the skull is tender and a lump can be felt. This is the hallmark of rubella.  Lymph nodes help the body fight infection by sending out disease-fighting cells and compounds and carrying white blood cells around the body. The lymph nodes themselves are small, bean-shaped glands that are distributed in different parts of the body such as the neck, groin and armpit. Viruses, bacteria and other foreign bodies are trapped in the lymph nodes (causing the swelling) and are destroyed by lymphocytes, which are special white blood cells. One of the main symptoms of rubella is an itchy rash that typically begins on the face and spreads rapidly to trunk and extremities.  At the end of the 2nd day, the rash begins to fade in the order that it appeared and by the 3rd day the rash has usually disappears. The medical term used to describe this type of rash is maculopapular - which is a combination of both flat, red patches and raised red bumps. Rubella infection triggers the occurrence of headaches, as the body struggles to fight the infection. However, it's not entirely clear why the pain signals causing the headache are triggered in the first place. Rubella infection sometimes alters a person's normal eating habits of. When higher body temperatures occur (above 98.6 degree F) the link between a person's taste buds and the brain stops working, leading to a loss of taste. Without a sense of taste, people tend to lost their appetites. With rubella, the lining of the eyelids and eyeballs sometimes becomes inflamed. This happens as a result of the same bacterial emboli (free flowing blood clot) that causes the maculopapular rash. Conjunctivitis results in inflamed eyelids and eyeballs. Whenever rubella infection is present, an aching joint pain can usually be felt. This is due to the secretion of inflammatory chemicals by the immune system, which causes muscles and joints to swell. Pain receptors in these muscles and joints then send pain signals to the brain, causing an aching sensation. Due to the presence of the rubella infection, a runny nose may occur. A runny nose keeps germs, dirt, pollen and bacteria from getting into your lungs by stopping them in your nose. When you blow your nose, the germs, dirt, bacteria and other microorganisms trapped in the mucus are expelled.
Summary:
Check your temperature. Feel for enlarged lymph nodes. Look for the development of itchy rashes. Be aware of any headaches you experience. Consider whether you've experienced a loss of appetite. Look for mild conjunctivitis around the eyes. Feel for joint pain and swelling. Watch out for a runny nose.
