How to Manage Our School Waste

 Schools use a lot of different products and materials everyday. They also generate waste. Schools can successfully recycle materials and some of  their waste. Different practices in schools can reduce the amount of materials used and waste generated, as well as increase the number of materials  being recycled. The NSW Government aims for sustainable waste management and higher rates of recycling.

1.    General Waste General waste is made up of all materials that cannot be recycled through other waste streams.  It is collected and transported to a landfill site where it is buried. Some landfill sites extract methane from decomposing waste for their  energy needs. Paper contaminated with food waste needs to go into general waste.

2.    Paper Recycling Paper and cardboard products are the most common items a school recycles. Secure documents are stored in locked bins before  being shredded and joining other paper fibres.

3.    Co-Mingled Recycling Co-Mingled recycling collects aluminium cans,  glass bottles, plastic bottles, steel cans,Tetrapaks and cartons for recycling.

4.    E-Waste Computers, phones, toner cartridges, printers and batteries all contain resources that can  be recycled.

5.    Organic Waste Schools can manage organic waste on site. Composting systems and worm farms manage fruit and vegetable waste, and mulching recycles green waste. Both processes produce nutrient rich materials for use on gardens.

The Corona

Corona means Crown. The halos are CORONAS's look around the Sun in Eclipse. Although there is always there that expands millions of kilometers into space. What's interesting about it is the fact, the Corona is hotter than the Sun of more than one million degrees Kelvin, or 106. Does anyone know how thermal energy can be transferred and increased from the solar surface into The Corona. This became the source of the heat which is still not fully understood.

The light from the Corona comes from three main sources, which are called by different names even though they all share the same volume of space.

K-Corona (K for kontinuierlich, "continuous" in Germany) is created by sunlight scattering off free electrons; Doppler broadening the reflected photospheric absorption completely obscures them, giving the appearance of a spectral line absorption without kontinuum. F-Corona (F for Fraunhofer) is created by sunlight bouncing off dust particles, and can be observed due to its light contains absorption Fraunhofer lines seen in raw sunlight; F-Corona extends to very high elongation angles from the Sun, which is called the zodiacal light. E-Corona (E for emission) is due to the spectral emission lines produced by the ion that is present in the coronal plasma, but can be observed in broad or forbidden or hot spectral emission lines and is the main source of the Corona's composition.

Quasar

In General, almost all of the Galaxy there is a big black hole that is very powerful. Galaxy is also the core of galaxy. The core of the Galaxy is usually found in the center of a Galaxy, where black holes is super great. Because the black hole is thus generating energy for the core of the Galaxy.

Quasar active galactic nuclei are located far away and is the object of a very bright, very energetic and very strong. This object emits energy. When viewed in telescopes, quasars would seem like a point-like stars. But it turns out that point is not a star but a very bright Galaxy nuclei that are far away from us.

Quasars are powered by an enormous black hole at the Galactic Center, which digest the material around it and emits very large gravitational energy. It's always a black hole devouring the surrounding materials to get into her. Like giant eating anything around him.

When the black hole digest the material around it, the materials spinning faster and begin to heat up. All particles rubbing against each other so that release large amounts of light and x-ray radiation as well. Well when material is then in heartily by the black hole, then the North and South poles black holes would release energy that astronomers are known as cosmic jets. The energy is released very quickly and darting energy is very strong.

Quasar themselves do not always come from the merger of the Galaxy, because it is not the result of a combination of the two galaxies. Quasar could be in galactic black holes that could evoke a quasar in it. But when two galaxies merge, super black hole still in it will indeed form a quasar. Because the black hole is generating energy for active galactic nuclei.

EXOPLANET

  

Exoplanets are planets outside the solar system. Started in 1992 with the first discovery, astronomers have found a planet around 837 in 660 planetary system around the milky way until now .The researchers believe that they will find many more planets in this year and a study in 2012 estimates that every star from the 100 billion or so in the Milky Way Galaxy has average 1-6.

Most of the discovery of Earth-like Exoplanets are not identified, they have characteristics closer to Jupiter or Neptune or gas giant.

Planets like earth are likely to exist in outer space, but astronomers had to find it in teh habitable zone are quite closeto the star that there is water in liquid form, but not tooo closely because it is too hot for life. A dozen exoplanets have been found in the habitable zone and teh spacecraft using the space telescope to identify 54 candidates other exoplanets.
