There are 42,209 persons living in the "comune" in 2017, for a population density of inhabitants/km².
Evolution of the population
The people from this "comune" are known, in Italian, as "maceratesi".
Macerata is twinned with:
Ban
A ban is an action used to stop people from doing something, either bad or dangerous. Ban can also be made on products. For example, Singapore, a country, bans chewing gum. Ban may sometimes be made on the Internet, where an administrator or a moderator with higher powers than other members can stop vandals from causing harm to others. Sometimes, users of a website say that moderators or administrators have banhammers that they use to ban bad users.
Neurology
Neurology is the branch of doctors that deals with the disorders of the nervous system. Neurology is about the medical diagnosis and treatment of conditions and illnesses of the nervous system. This can include both the physical condition of the brain, nerves, and brain messages between the body and the nervous system. Neurological practice relies heavily on the field of neurobiology, which is the scientific study of the nervous system.
Steve Irwin
Stephen Robert Irwin (22 February 1962 – 4 September 2006) was an Australian zookeeper, television personality, wildlife expert, environmentalist, and conservationist. He was famous for the television program "The Crocodile Hunter", a well-known real-life animal program that he made with his wife Terri Irwin. Irwin's character and adventures on his program made him an international star.
Irwin's mother and father were Lyn and Bob Irwin was born in Melbourne, Victoria, Australia. The family moved to Queensland in 1970, when Irwin was 8. Bob Irwin was very interested in reptiles (a type of animal that includes snakes and crocodiles). When the family moved, Bob and Lyn Irwin started the small "Queensland Reptile and Fauna Park". Irwin lived there until he became an adult.
Irwin worked in his family's park when he was nine: feeding the animals, and taking care of the grounds. He began working with crocodiles when he was nine, and became a crocodile-trapper (someone who traps crocodiles without killing them) when he was older. Irwin trapped crocodiles that were near places where people lived, and kept them for the park. He also worked for free for the Queensland Government's "East Coast Crocodile Management program".
Irwin became head of the park in 1991 and changed the name to "Australia Zoo". In 1992, at the Zoo, he met and married Terri Raines. As part of the marriage event, Irwin and his wife went on a journey to trap crocodiles. The journey was recorded for television and became the first part of the television show "The Crocodile Hunter". This show made Irwin famous. "The Crocodile Hunter" has been seen by people in 120 countries across the world, and has a large number of fans (people who like it very much) in the UK and Australia.
Irwin made the zoo larger by adding the "Animal Planet Crocoseum", a place where rainforest birds can be seen, and the "Tiger Temple". He also started the "World Wildlife Warriors" (which was named the "Steve Irwin Conservation Foundation"), an organization that tries to preserve rare animals that are in danger of dying out.
In 2003, one of the locomotives on "The Ghan", the Adelaide to Darwin railway was named the "Steve Irwin".
At about 11:00 a.m. Australian eastern standard time (01:00 UTC) on 4 September 2006, Irwin was cut in the chest by the tail of a stingray (a large sea animal) while snorkeling (a way of swimming using a tube to help you breathe under water) in Batt Reef, near Port Douglas in Queensland, Australia. He died from the wound. At the time, Irwin was being recorded for a television show, "The Ocean's Deadliest". Bad weather had stopped recording and Irwin took the time to record some different pictures for another program. Irwin's friend, John Stainton, was on Irwin's boat. Stainton says Irwin swam too near to one of the animals - "He came on top of the stingray and the stingray's barb "(a point on the stingrays' tail)" went up and into his chest and put a hole into his heart". His wife (Terri Irwin) did not find out about his death until a few hours later because she was trekking in Tasmania.

Search and seizure
Search and seizure is an act that police and other law enforcement authorities are allowed to do. It is when they search a place for evidence of a crime. If they find that evidence, they may take it. They usually knock the door down with a search warrant. Warrants are a document stating that the government has permission to go into a building due to found evidence.
Impulse (physics)
In classical mechanics, an impulse is defined as the integral of a force with respect to time:
where
Impulse is also described as the change in momentum. If the force and the mass of the object do not change, impulse can be simply expressed as:
where
Ruler
A ruler (or 'rule') is an instrument of measurement. Rulers measure length. Length is how long or short something is. Most rulers work by having numbers (parallel to the measuring edge) and little lines (perpendicular to the measuring edge). Rulers can also be used as a straight edge to draw lines with.
Rulers come in many different forms. They can be made of plastic, wood and metal, and other materials. Rulers also come in a variety of lengths. For example, there are 1 metre rulers, 30 centimetre rulers, 20 centimetre rulers and 15 centimetre rulers. These are examples of metric rulers. You can also get 1 yard rulers, 18 inch rulers and 6 inch rulers, etc. These are examples of imperial rulers.
Mutation
In biology, a mutation is a change in the genetic material. This means changes to the DNA or to the chromosomes which carry the DNA. These changes are heritable (can be passed on to the next generation) unless they have lethal effects.
Mutations can happen for several reasons. It can happen because of errors when "meiosis" produces the gametes (eggs & sperms). Damage by radiation, or by certain chemicals may cause mutations. Mutations occur at random.
Also, by derivation, an individual carrying the mutation may be called a mutant or a "mutation". So is the trait (character) most obviously affected by the mutation.
When DNA is copied mistakes are sometimes made – these are called mutations. There are four main types of mutations:
These terms are explained in the third diagram.
Mutations may be bad for the organism, or neutral, or benefit the organism. Sometimes mutations are fatal for the organism – the protein made by the 'new' DNA does not work at all, and causing the embryo to die. On the other hand, evolution is moved forward by mutations, when the new version of the protein works better for the organism.
Mutations are the ultimate source of variation, upon which "natural selection" acts. What happens is that some mutations affect the organism's ability to live and reproduce. This is an important part of the theory of evolution. The amount of heritable variation carried by a population can be huge, and as a result natural populations can change and adapt to conditions in their environment.
