On the day of his resignation, Blair was made an official envoy in the Middle East. In 2004, he started the Commission for Africa. He continued work as a commissioner after his service as Prime Minister ended.
Accident
An accident is when something goes wrong when it is not meant to. Physical accidents are things like collisions, injuries, and falling. Non-physical accidents are things like accidentally telling someone a secret, forgetting something important, or deleting an important computer file.
Road accidents kill thousands of people each month in the United States, and thousands each week in the world. They injure more thousands each week. The majority involve a car but there are also many bus, truck and bicycle accidents. Aircraft crashes, ship sinkings and other transport accidents also attract much attention.
Injuries from accidents, however, are more numerous at home than elsewhere. They attract less attention because only a few people are hurt at a time.
Often, accidents are investigated so that we can learn how to avoid them in the future. Sometimes by studying an accident we can discover new things, for example penicillin.
Most of the deaths resulting from injuries are caused by fire accidents. Thus, accidental fires are one of the leading causes of unintentional deaths. The main cause of death in fire incidents is burning, but inhalation of smoke and toxic gas causes death as well. Often the cause of the fire is very simple and unexpected, such as forgetting a candle near something flammable, defect in the hardware, or old electrical wires. So most of the large fires are caused by simple reasons.
Industrial accidents such as mine cave-ins and the West Gate Bridge collapse also kill and maim many workers. The Bhopal disaster killed thousands, mostly not workers.
An accident at work is defined as an external, sudden and violent event. Work accidents happen while an someone is working. It may cause the injury or death of the worker or someone else. For an accident to be a work accident, there must be a direct or indirect relationship of cause and effect between the accident and the work.
Many construction workers are injured. There are multiple reasons for that, but the main reason is working on the edge of high buildings without using a safety belt. Thus, you have to follow the safety rules when you are working on these places.
Chemical accidents can happen in a laboratory. Especially, some students make chemical mistakes that injure them seriously.
Acne
Acne is an infection of the skin, caused by changes in the sebaceous glands. The most common form of acne is called acne vulgaris, which means "common acne". The redness comes from the inflammation of the skin in response to the infection.
Oils from the glands combine with dead skin cells to block hair follicles. Under the blocked pore, oil builds up. Skin bacteria can then grow very quickly. This infection makes the skin become swollen and red, which becomes visible.
The face, chest, back, and upper arms are most common places for acne to happen.
Acne is common during puberty, when a person is turning from a child into an adult, because of high levels of hormones. Acne becomes less common as people reach adulthood.
There are lots of acne treatment methods available, including natural treatments.
People of all ages can get acne, although it occurs more commonly in adolescents. Acne can affect people physically, psychologically, and socially.
Acne causes scarring, and acne pustules can be very painful and sensitive.
People suffering from a bad case of acne, especially adolescents, can develop low self-esteem which can lead to depression.
Low self-esteem issues can make a person suffering from acne withdraw from many social events. It makes developing new personal relationships (especially love relationships) more difficult. Low self-esteem can also cause problems with career advancement as the person may find it difficult to present a positive attitude. This may sometimes even lead to suicidal thoughts. Some of the treatments for acne have also shown a link with more suicide attempts.
Exactly why some people get acne and some do not is not completely known. These can cause acne, or make it worse:
Aspirin reduces inflammation which in result, reduces facial redness due to acne.
Many things are sold to treat acne, the most popular being benzoyl peroxide. Many of these things have not been scientifically proven to help acne. However, a mix of commercial and homemade treatments can help with acne for various reasons.
Popping a pimple should not be done by anyone but a qualified dermatologist. Pimple popping irritates skin, can make the bacteria spread, and can cause scars. If you must pop a pimple yourself, it is advised to apply warm water to the area before popping it and to wash your hand thoroughly before beginning so as to avoid spreading bacteria via the hands. Applying hot water will open up the pores and reduce the damage because it will require less force to pop it.
There are 650 million people in the world with acne, which is around 9.4% of the global population. More females are getting acne than males (9.8% versus 9.0%). Acne affects 40 to 50 million people in the United States (16%) and approximately 3 to 5 million in Australia (23%). Acne affects people of all ethnic groups.
Bad acne often leads to bad scars where the skin has the shape of a volcano. It is difficult and expensive to treat acne scars.
These are some ways acne scars can be treated:
Dinosaur
Dinosaurs and Dinosauria (Latin: Dinosaurium; meaning "terrible lizards") are a varied group of Archosaur reptiles. They were the dominant land animals of the Mesozoic era. Over 500 different genera of dinosaurs are known. Fossils of dinosaurs have been found on every continent, and there are still frequent new discoveries.
Dinosaurs appeared in the Upper Triassic, about 230 million years ago. The earliest date of a dinosaur fossil is that of "Eoraptor" and "Herrerasaurus" from the Argentine, and "Saturnalia" from Brazil, 237 to 228 million years ago. By the early Jurassic they were the top land vertebrates, and dominated most environments on land. They continued until the sudden K/T extinction event 66 million years ago.
From the fossil record, we know that birds are living feathered dinosaurs. They evolved from the earliest theropods during the Jurassic. They were the only line of dinosaurs to survive to the present day.
Dinosaurs had adaptations which helped make them successful. The first known dinosaurs were small predators that walked on two legs. All their descendants had an upright posture, with the legs underneath the body. This transformed their whole life-style. There were other features. Most of the smaller dinosaurs had feathers, and were probably warm-blooded. This would make them active, with a higher metabolism than modern reptiles. Social interaction, with living in herds and co-operation seems very likely for some types.
The first fossils were recognised as dinosaurs in the early 19th century. Some of their bones were found much earlier, but were not understood. William Buckland, Gideon Mantell and Richard Owen saw these bones were a special group of animals. Dinosaurs are now major attractions at museums around the world. They have become part of popular culture. There have been many best-selling books and movies. New discoveries are reported in the media.
Dinosaurs are united by at least 21 traits in their skulls and skeletons. These common characters (called 'synapomorphies') are the reason palaeontologists are sure dinosaurs had a common origin.
However, when definite dinosaur fossils appear (early in the Upper Triassic), the group had already split into two great orders, the Saurischia, and the Ornithischia. The Saurischia keep the ancestral hip arrangement inherited from their Archosaur ancestors, and the Ornithischia have a modified hip structure.
