PP (polypropylene) :- Transparent, light and strong, this material can be used as both a plastic and a fiber. Easily colored, it does not absorb water. It is used to make textile fibers, couplings, containers for transport, furniture, carpets, ropes and food containers.
PS (polystyrene or styrofoam) :- One of the most important thermoplastic materials, it is transparent, hard and inflammable, very bright and inert against many corrosive agents. It can be given shiny or opaque colors. Polystyrene is commonly used to replace glass, aluminum and wood because it is cheaper. It can also be used in packaging materials (including for foods), containers, boxes, lamps, disposable objects, cups and toys.
Pete Doherty
Peter Doherty (born 12 March 1979) is an English musician. He was born in Hexham, Northumberland. He is in the popular rock band The Libertines. He is also in a band called Babyshambles.
He receives a lot of media coverage for his drug and legal problems and the relationship he had with fashion supermodel Kate Moss. Doherty has been convicted of many crimes. Some of the crimes are drug offences, car theft, and driving with a suspended licence. He has served prison sentences for drug possession and burglary.
Polycarbonate
Polycarbonate is a transparent (something which can be seen through) thermoplastic. This material is tough and stable. It can resist a high temperature of 138°C (280°F) and a low temperature of -40°C (-40°F). It is stain resistant and non-toxic. The weight of polycarbonate is one sixth of glass.
Industries use polycarbonate for making different products, from bulletproof windows to CDs and DVDs. The main advantages of polycarbonate are high strength and light weight.
Industries use clear polycarbonate to make glasses. This is because it has very good transparency and durability. Lenses made from clear polycarbonate can be thinner than lenses made from regular glass.
Companies that make electronic equipment use polycarbonate to make the cover of mobile phones, laptops and other products. Although polycarbonate is not poisonous, the process of making polycarbonate uses toxic chemicals. (See Bisphenol A).
Natural disaster
A natural disaster is a major adverse event caused by the natural processes of the Earth, consisting of floods, hurricanes, tornadoes, volcanic eruptions, earthquakes, tsunamis and other geologic processes. A natural disaster causes loss of life or property damage, and leaves some economic damage afterwards costing millions.
And often human activities also make causes of natural disasters, such as climate change and deforestation.
It is the damage to humans and their property which counts most. Therefore, one can say: "disasters occur when hazards meet vulnerability". If a strong earthquake happens in uninhabited areas, it is usually not seen as a disaster or a loss.
An adverse event will not rise to the level of a disaster if it occurs in an area without vulnerable population. In a vulnerable area, however, such as , an earthquake can have disastrous consequences and leave lasting damage, which can require years to repair.
A volcanic eruption occurs when hot materials from the Earth's interior are thrown out of a volcano. Lava, rocks, dust, and gas compounds are some of the ejected materials.
Eruptions can come from side branches or from the top of the volcano. Some eruptions are terrible explosions that throw out huge amounts of rock and volcanic ash and kill many people. Some are quiet outflows of hot lava. Several more complex types of volcanic eruptions have been described by volcanologists. These are often named after famous volcanoes where that type of eruption has been seen. Some volcanoes may show only one type of eruption during a period of activity, while others may show a range of types in a series.
Ibanez
Ibanez is company that makes guitars. The company is from Nagoya, Aichi, Japan. The company was started by Hoshino Gakki. The company is very big and sells many guitars to musicians.
Landslide
A landslide includes a wide range of ground movements, such as rock falls, deep failure of slopes and shallow debris flows.
The biggest reason for a landslide is that there is a slope and material goes down the slope because of gravity.
But other things also contribute to landslides:
An underlying reason is the nature of the material. For example, a thixotropic material such as mud or sand and water, can change from a gel to a sol by adding water or pressure, or shaking. It goes from being stable one minute to fluid the next minute. The greatest disasters, like lahars or mudslides, happen suddenly. It is possible for much of a volcano to just slide down suddenly, as with Toba, Krakatoa and Mount St Helens.
2040s
The 2040s decade will begin on January 1, 2040 and will end on December 31, 2049.
This decade will be called "the twenty-forties". The Roman number will be MMXL.
The first baby boomers will be 100 years old in 2046.
Americium
Americium is a chemical element. It is a radioactive metal. It has the chemical symbol Am. It has the atomic number 95. In chemistry it is placed in a group of metal elements named the actinides. Americium is a transuranic element (Transuranic means after uranium. All the elements used after uranium are man-made). It is a radioactive element that does not exist in nature. Americium has to be made. It has a silver color. Americium is made by bombarding a plutonium target with neutrons.
It was the fourth transuranic element to be discovered. It was named for America, like Francium was named for France.
The longest half life of any type of americium is 7370 years.
Americium is used in most smoke detectors. The level of radioactivity is not enough to cause cancer, so it is safe to for the people in an area where smoke detectors with americium are in use.
Daddy Yankee
Ramón "Raymond" Ayala, known as Daddy Yankee (born on ) in San Juan, Puerto Rico is a Puerto Rican reggaeton singer. Ayala is famous for making songs in both English and Spanish, but Spanish is used more than English.
During his childhood, Ramón grew up with the influence of his family musician, including those of his father and some members of his mother's family. At twelve, he began singing songs inspired by reggae and hip-hop.
Ramón wanted to become a professional baseball player, he will have to give up this goal after being shot in a neighborhood brawl when he was seventeen. He received two balls of AK-47, one touched his arm and the other touched him on the level of the right thigh, where he was wounded for life. After this incident, he will take a closer look at the underground rap movement, which was nascent at the time.
He began his career flirting with hip-hop and with Latin rhythms like dancehall, but we can say that his greatest hits will come when he begins to perform and produce his Latin hip-hop songs. He will be one of the first artists to perform internationally in reggaeton music.
Ramón invested in the world of reggaeton for thirteen years before experiencing success. He first recorded with DJ Playero, of which he is the featured artist in a production called Playero 37, which will be released in 1992. He has also partnered with artists such as Laurena Snoop Dogg, Nicky Jam, Pitbull, Mey Vidal , DJ Blass, Eric DJ, Eliel, Nas, Tony Touch or members of the G-Unit, Lloyd Banks and Young Buck.
His album Barrio Fino is an essential music to the style: it comes from the deepest of his roots of his life but also his personal experience, in the neighborhoods or residential areas of Puerto Rico. The first excerpts from this album are titled Gasolina, King Daddy and No me dejes solo featuring Wisin y Yandel.
His song, Impacto, released on of 2007, appears in the San Juan Sounds radio station's playlist of Rockstar Games' Grand Theft Auto IV and games.
