While being seen best closer to the poles, polar lights can be seen all over the world from time to time and even on other planets, and are also many different colors. They show up as glows or curtains of color.Green, blue, and red are common colors for auroras. Charged particles from the sun come to the magnetic poles of the earth and they collide with atoms of oxygen and nitrogen. Oxygen tends to give a green or brownish-red color while nitrogen gives a red or blue color. Altitude has a huge influence in the color of polar lights. At high altitudes the oxygen causes a red light. Lower down the oxygen will give a green light and the nitrogen will give a blue and red light. Then finally there is lower down when only the blue and red from the nitrogen is seen. The most common color for an aurora is green, followed by pink which is a mixture of the green and red colors. The rarest color of aurora is the red light which is caused by a collision only 200 miles (320 km) above the earth!

The campaign was originally inspired by Karl Weyprecht, an Austro-Hungarian naval officer. He was a scientist as well as the co-commander of the Austro-Hungarian Polar Expedition (1872-74Z); however, Weyprecht passed away before seeing the IPY come to life in 1882-1883. The First International Polar Year was proposed by Georg Neumayer, who was inspired by Weyprecht.

The motivation behind this international research collaboration is to research polar areas and the singular phenomena that occur in these regions. IPY seeks information about ‘changing snow and ice’, ‘global linkages’, ‘neighbors in the north’, and ‘discovery.’ Thousands of scientists from over 60 countries come together to research, gather information, seek knowledge, and discover the inner workings of the remote polar regions of the world. Ultimately, because of the amount of money, time, and effort that is put forth for this program, International Polar Year does not occur every year like a holiday.

Years ago I first made a trek in Lapland alone. It was September and I walked from hut to hut in the northwest of Finland, near the border with Sweden. Day and night were long and I had to make sure the darkness have reached the next hut. That worked. Since the wood stove quickly spread a warmth and also served as a stove for a simple meal. It asked later in the evening some courage to warm and safe housing to leave the hut – the toilet was outside. As the wind rustled through the pines and birches been virtually bare. Suddenly my attention was drawn by a glow between the trees.I was surprised. My first thought was that it should come from a more distant residential areas. But I realized immediately that this could not, because there was no place in the wider area of ​​any significance. I climbed a hill to see the glow better. When I clear view to the north had been, it dawned on me that this was my first experience was with the Northern Lights. In the silence of the frosty night veils of light moved across the sky, mostly in shades of green, but also infused with red and yellow. As I watched, I felt the flowing movements out there not only played out in the sky, but inside myself. I stood silent and amazed. A feeling of warmth and happiness spread in me a deep religious feeling of respect and gratitude. I felt included and one with this mysterious weaving. The stars were visible through the colorful veils.
I do not know how long I am there still. At one point I noticed how cold I had become. I tore myself loose from the scene and hurried to the warm shelter of the hut. With a feeling of deep satisfaction I fell asleep, knowing that the best thing I have ever seen in my life was out there over the roof thriving game continues playing and that I would soon become a part of would be after I would have fallen asleep .
In this article I am not so much concerned with the theories developed by science for the northern lights (aurora borealis = dawn of the north) to explain. These theories are almost always boring and not very creative and do not reflect the reality of the experience. Aristotle, the founder of natural science, was his conception are close to this reality. His ideas are imaginative vision and scientific interpretation is closely related. This is reflected in Aristotle’s description of the aurora displays. He thought that the earth is releasing a vapor, at high altitudes in the solar fire ignites in contact and there, so the colorful flames of the aurora to spread.
We will see that Aristotle’s understanding of the key of a contemporary view by state humanities.

The sixtieth latitude

Norwegian priest and author of The Christian Community Harald Falck-Ytter describes in his book Kalevala the sixtieth latitude as a threshold for humanity. Our civilization is reduced to this threshold, facing a future where space inside. The people north of this latitude, including Alaska and in northern Europe, live under conditions in which only the future of humanity can be apprehended consciously.
Cities like Oslo, Stockholm, Helsinki and St. Petersburg are at or near the sixtieth parallel. In what way is this a limit or threshold? North – and south in the southern hemisphere – the sixtieth parallel, we find an area that ethereal, atmospheric constitutes a self-enclosed world. South of this boundary move the air and water flows from west to east, north of it the other way around. Since air and water to move from east to west. Where oppositely moving water and air flow to each pass, and friction creates the impression of a grinding operation. The borders of these opposing currents and eddies created whirlpools. These form a hollow space in which life forces can be yielded and again.
The sixtieth latitude is also a light border. It is the southernmost border where during the midsummer light around the midnight hours the intensity of the Dawn. The sun moves close to the northern horizon and only one hour long off: dusk becomes dawn. The area north of the sixtieth parallel constitutes a kind of skullcap, a cap on the crown of the earth, which the experience of time changes. Time here becomes expensive, especially in summer and winter. The more north you get, the more the years dividing itself into a long day and a long night, with the character of spring and autumn dawn and dusk take. Here unfolds a process of time to space, the ethereal, the world of life forces, only by a gossamer veil of sensuous phenomena covered up. At the edge of the polar ice creates a kind of rotating, sliding motion and thus model the dome with his small force impulses to continually move the air around poolkalot those inherent therein.

When charged particles enter the atmosphere at high altitude (around 250km), they can with their high energy excitation of atoms and molecules: these electrons are placed in other jobs or even thrown out of the atom (ionization). In recombination and de-excitation is a surplus of energy in the form of light emitted. This light is what we see as auroras. The color of the light varies depending on the type of atom or molecule and the energy of the electron orbits.

The charged particles are in space around the Sun, but have a high concentration and speed when the sun has an eruption (called a Coronal Mass Ejection, or CME). These eruptions caused by “magnetic circuit” in sunspots. The magnetic field lines in sunspots are sometimes very complex, and become unstable. When the field is suddenly short-circuited, are massive amounts of energy which is then an explosion on the surface of the sun damage. The particles (mostly protons) that are ejected into space this may arrive at the earth as the explosion on the side of the sun we see.

Every 11 years, activity on the Sun called a ceiling. There are a few more years on average, heavier bursts. The chance of auroras in this period also increased, and, in addition to lower latitudes. Normally only aurora around and above the Arctic circle to see (both south and north). The last maximum was around 2000-2001 and several times in the Netherlands has yielded spectacular auroras. The following minimum in 2006, although in 2004 and 2005 the aurora also occasionally been seen in the Netherlands. The attentive observer will on average once a year or Northern Lights can be seen in the Netherlands, and once every 3 or 4 years spectacular auroras.

Observing aurora

The weak form of auroral manifests itself as a green belt on the northern horizon. If the aurora is active, you often see a red glow, and if it has been more active in this pink, red, purple or bluish rays to see. These rays move fast, but usually not as fast as you can see them visibly change. Often when a weak form of aurora is visible, it can suddenly from one minute to another “flare up”. If there is any form of aurora over the Netherlands to see, so if possible you should keep looking all night. Many observers in the Netherlands went to bed after hours of inactivity, to later read on the Internet that it was very spectacular half hour of sleep. It’s really about as dawn commitment, because you can not perceive!

The different colors of the aurora caused by the different gases in the atmosphere. Aurora is at altitude to see, from roughly 80 km above 200 km. At these altitudes, the gases in the atmosphere is not mixed, but stratified to specific gravity. Green and red caused by oxygen (O), but red can be less than the green caused by nitrogen (N). Nitrogen can also cause a pink glow. Blue aurora is rare and occurs when the aurora is so active that hydrogen (H) is struck.

The great geomagnetic storms caused by CMEs often cause large-scale auroral extending far towards the equator can be seen as the aurora over the Netherlands on 7 April 2000. This aurora was in Italy to see.

Photography

To aurora to shoot you use a fast film, such as 400 or 800 ISO. Better to use a digital SLR if you slightly lower resolution compared to film is no objection. Wide angle lenses are well suited, because it allows you a large portion of the air picture. Active aurora is vast, and the whole phenomenon can only be whole picture with a fish-eye lens.

Use a fairly large aperture like f/2.8 or f / 4, but prefer not to use the widest aperture of the lens to prevent vignetting (where the corners of the image darker). Usually you do a few seconds with fast film (up to 10 or 20 seconds) long exposure. If you need longer exposure, the aurora may be slightly washed out, because it changes.

A digital camera has the advantage that you can control the exposure time directly by looking at the result. The very best for a digital camera and a film camera to use. The digital camera do you use this as an exposure indicator, and the film for serious high-resolution pictures.

General
The white polar bear dates back from 57 million years ago. The kind that we know is not very old, about 200,000 years. Previously, these bears were much smaller. Now there are peaks of over 900 kg. But the average polar bear weighs between 700 to 800 kg. The average polar bear measures about 2.8 meters.
Polar bears have an excellent vision. They are especially good at night hunting for food. A polar bear is also extra padding on the eyes. To protect the eyes against the artistic ment and the freezing wind, so the eyes do not freeze. The temperatures in the Arctic could easily go below -30. The smell of a polar bear is incorrigible, they can smell food up to 32 km far.
Other characteristics is that the polar bear’s hearing is well developed, at least better than in humans.

Reproduction
Polar bears usually mate between March and June. The transfer of a polar bear takes a long time, between 200 and 250 days. This is because the gestation period is extended. The young feed on milk fat and calorie diet of the mother.
Only the female cares for the boy, the male polar bear would be able to kill the boy. The young are suckled for 1 to 3 months, after about 24 to 28 months, the young begin to be independent. Polar bears on average gets to live 21 year, although there are polar bears who lived over 40 years.

Hunt
A famous hunting techniques of the polar bear is that he first looks for holes in the ice, here he remains motionless and alert guards. At the least movement he gets out, and usually has a fish on the hook, the polar bear is very quick to react. It is even known that polar bears hunt seals out of the water. The polar bear is very strong and can be interchanged without a beast of 70 to 90 kg of pulling out of the water, with relatively little effort. The claws of a polar bear will damage the “seal” from the water, usually so bad that he was not in a position to induce or against baulk.

When installing your water tank, first you need to check your draining system. Proper rainwater passage is important and must be ensured. A gutter should be placed and mounted because this will make the collection of water possible. Make it a point that it is properly covered to avoid rocks or stones, leaves and other trash from entering the tank. You need to regularly clean and inspect the guttering to ensure there is proper supply of water.

Poly tanks and a rainwater tank can be installed either below or above the ground. When choosing where you want these water tanks installed take a look at some of these factors. For one, tanks that are installed above the ground are deemed common as well as safe. This approach is both easy and cost effective. You can easily spot a leak if in case there is any and there will be no hassles in cleaning and draining them. The only disadvantage of putting it above ground is that it will eat up an ample amount of your space. On the other hand, underground water tanks are well hidden, intact and will not affect your future plans of landscaping because they are situated below the ground and you can easily build a pavement over them. However, it will be difficult for you to locate leaks and it will also take a lot of time (and money) to set one up because of the digging process.

Containerized wastewater systems are designed for harsh and remote environments where it is not feasible to set up a permanent facility. Such systems often store polluted water that will be cleansed later on in the process. Another advantage to a containerized approach is portability, and this attribute makes it possible to move your wastewater treatment to areas where it is needed.

It is an option to combine several different wastewater treatment techniques to form a working system. An example of this are certain types of sewage treatment wastewater plants. Through the use of traditional techniques, the waste is cleansed to specified levels. A second process involving detergents and cleansers is then implemented to make the water byproduct suitable for reintroduction back into nature.

Consult with your trusted wastewater treatment experts when deciding whether or not to develop a wastewater system. Often times, a second-step in treating polluted water is imperative for making the least environmental impact. A wastewater system is important in ensuring that no dirty water ends up in an inappropriate place.

The population, can do much to improve the air we breathe all.

Excessive car use causes a high degree of air pollution and if we add that many of them are in poor condition and fired numerous pollutants that directly affect the health of individuals, we realize how much we can contribute to the environment.

The air we breathe is composed of 78% nitrogen, 21% oxygen, 0.093% argon and a portion of steam or air, when we talk about air pollution, we refer to the alteration of this composition, produced by natural causes caused by man, the first can not be avoided, but the second is our obligation to avoid them. The sources that cause air pollution are classified into fixed installation are all set in one place that is intended to develop operations and industrial processes, commercial and mobile sources, which are all non-fixed equipment or machinery with combustion engines and similar operation on his generated pollutants in the atmosphere.

Industry and transport are the two main sources of air pollution. Official data show that the public transport of passengers, cargo and individuals, generate 80% of total air pollutant emissions, 3% represents the industry and the remaining 10% services trade and 43 million are consumed liters of fuel per day for 10% of government budget, is intended to the health sector concerning cardiovascular and respiratory diseases there are 3.5 million vehicles circulating daily in roads, highways and motorways.

The main pollutants given off by motor vehicles and affecting the health of the population, are: carbon monoxide, which is formed due to incomplete combustion in motor vehicles using gasoline. The hydrocarbons formed by components of gasoline and other petroleum products. Nitrogen oxides are pollutants that by themselves are no problem, but on contact with sunlight, produce toxic compounds. Ozone is one of the top layer of the earth, and helps filter ultraviolet rays from the sun, but if you are at ground level becomes a very powerful cleaner. Lead, originates from the fuel, is used as anti-knock additive for gasoline and particles that can float or sediment and are known as total suspended particles.

The first mandatory vehicle Verification Program, was voluntary character in 1982, in 1987 was made mandatory for private cars and model year 1976-1982, the intention for this was that by the end of 1988, the gradual implementation of the program was to cover all private cars. Since 1988 the program became mandatory half-yearly.

The verificentros are private companies responsible for carrying out the task of inspecting the vehicles are in good condition, equipped with specialized equipment to measure the following gases: nitrogen oxides, hydrocarbons, carbon monoxide, carbon dioxide and oxygen they monitored by the authorities, such verificentros have locks which are: video recording of checks throughout the day, the electronic count of the number of vehicles entering and leaving the verificentro, technical audits, administrative and calibration logs operation, internal and external image as well as information and safety signs, weekly reports, voice complaints, etc.

To have cleaner air, it is need to help improve our environment, nature is all and in our hands to keep it to bequeath to our children a healthy environment.
