Nutrient Content in The Eel

Did you know about the eel?
For some, the eel is a ridiculous animal even disgusting, but actually a lot of nutritional value in it.
Eels or commonly called welut (ed: Java), which has the Latin name Monopterus Albus Zuieuw (eel rice) has a lot of nutritional value. The nutrients contained in the eel has a protein equivalent to meat, and has the highest energy content than beef and chicken eggs.

Eels have a protein content by 18.4 g/100 g of meat, equivalent to 18.8 g/100g protein of beef, but higher than 12.8 g/100 g egg protein, and energy content contained in the eel is at 303 kkal/100gr meat. Eel energy value is much higher than 162 eggs and kkal/100g skinless beef kkal/100 207 gr.

Now look at the data above, the eels can be used as a cheap alternative source of nutrition, compared with the price of beef and egg prices. Eels are very suitable consumed at the age of infants and the elderly because of the value of high protein digestibility yanng. Eel it is equally delicious beef in the appeal. So, eels could be alteratif food is cheap and of high nutritional value.

Improving Our World One LED Light at a Time

LED lights are a wonderful invention that has changed the way the world is lit. Not only are they long lasting, they have many environmental benefits. LED lights are four times more efficient than a regular incandescent light bulb and last 10 times as long. LED lights also use between 50 and 80 percent less energy than an incandescent bulb.

LED lights are considerably less expensive to operate, however are a little more expensive to purchase. LED home lighting requires only one third of the energy that an incandescent bulb will use. A single 18-watt LED light can replace a 75-watt incandescent and in the lifetime of the LED light, will save 570 kWh of energy. At a basic eight cents per kilowatt rate, that equals $45 dollars in energy bill savings.

By switching to low energy LED home lighting in your home, even one bulb will keep one half of a ton of carbon dioxide out of the atmosphere through the lifetime of the bulb instead of using incandescent bulbs. Switching also keeps sulfur oxide and nuclear waste out of the atmosphere as well, leading to a cleaner world and one that will last much longer. By simply switching, our environment could easily revitalize itself without having to deal with the excess carbon dioxide, sulfur oxide and nuclear waste emissions that are currently being released into the atmosphere every day. Even changing one lonely bulb in every home to LED home lighting would make a significant impact on the environment.

Biodiesel as an Alternative Fuel

Biodiesel fuel is a fuel made from the oil of certain oilseed crops such as soybean, canola, palm kernel, coconut, sunflower, safflower, corn and a hundreds of other oil producing crops. The oil is extracted by the use of a press. The oil is then mixed in specific proportions with other agents which causes a chemical reaction. The results of this reaction are two products, biodiesel and soap.
After a final filtration, the biodiesel is ready for use. After curing, the glycerin soap which is produced as a by product can be used as is, or can have scented oils added before use.
Biodiesel fuel is not a new development; however it has gotten quite a lot of publicity lately. This is largely due to the rising cost of crude oil which puts a strain on the consumer's wallet at the gas pump. Biodiesel fuel is one alternative to relying on fossil fuels to operate our vehicles.

In 1895 Dr. Rudolph Diesel introduced the first diesel engine intended to run on vegetable oil. In 1900 he presented his engine at the World Exhibition in Paris. This diesel engine used peanut oil as fuel.
In 1912 Dr. Diesel predicted that in the future the use of vegetable oils as a fuel may be as important as the use of petroleum and coal was in his day. With the volatile nature of oil producing countries, and the ever surging cost of crude oil, interest in vegetable oils as fuel has been rekindled, so it seems Dr Diesel may have had a glimpse into the world of today.

Climate Change - The Coming Crisis

While many contend that there are different reasons behind the changing of our climate, few can deny that our planet is going through a period of immense changes. While some may discredit the science, global warming is one of the main hypothesis for why our planet is heating up. In this article, we'll try to explain some of the science behind global warming so that you can understand the problem more clearly.
According to numerous scientific studies, our planet's surface temperature has increased by about 1 degree Fahrenheit within the last century. Most of this change has occurred in the past two decades, prompting the question: are our lifestyles accelerating this global change? The evidence definitely seems to point in that direction.

Many scientists point to the emission of greenhouse gases as one of the leading reasons that we are undergoing this global change. Carbon dioxide, methane, and nitrous oxide are some of the main compounds that we are releasing more and more, causing something known as the 'Greenhouse Effect'. This occurs due to the fact that these gases tend to trap heat, and when they are released into our upper atmosphere, they trap some of the heat energy that would normally be reflected by our earth's natural processes.

The Effects Global Warming May Have On Our Planet

While many realize that global warming is occurring on our planet, few understand the implications that this may have on our way of life. These rising global temperatures are going to cause a host of changes on our planet, and we need to act now or prepare to adjust to some very profound changes.

Practicing Concentration with Yohanes Surya

The human brain is a super computer powerful God's creation. All parts related to one another in a complex network. Remarkably, the brain can be trained to concentrate or remember. According to Olympic champion remember (mind Olympiad), the brain can be trained what is great, even to remember a long series of numbers. The world record for the recall is held by Yip Swee Choi is able to recall 60 000 series of numbers!
Just as remembering, concentration can be trained. To train it we can begin to read for 50-10 minutes, can be assisted with the music to read (usually a type of baroque music). Then we increase any longer, to the extent that we want.
We often have trouble concentrating because sometimes we train the brain to not concentrate. For example, when watching TV, just 10 minutes walk, suddenly broke our concentration because there are no ads or want to change to another channel. If that we continually do, we are only able to concentrate very brief. (SBR: yohanes solar)

The Freon and Layer O3 (Ozone)

The Freon is a chemical compound that was created in order to use the AC (Air Conditioner) and Almari Es (Refrigerator). Each Freon compounds designed to have a certain boiling point and is stable, so it will not react directly with the materials at a fridge, however if released into the freon-free air can not be explained by other compounds at low altitude from the surface atmosphere.

When the freon gas reaches the ozone layer, which contained a layer in the stratosphere as far as 12-50 km from the earth's surface, then the freon gas is depleting the ozone layer.


Then if the ozone is it?

Ozone is a type of compound consisting of three oxygen atoms O (which is written O-3), where the ozone molecule is useful for life on the earth's surface because it absorbs UV radiation, so it is not directly affected so harmful to living things.

Chlorine of freon can bind one oxygen atom from ozone to form chlorine-monoxide. Ozone molecules originally beratom three are transformed into ordinary oxygen atom with two atoms only, so this molecule to the next could not stem the effects of UV radiation.

Increased UV can cause skin cancer, cataracts in the eye, reducing the body's immune system, resulting in low production of algae, which become food for the food chain.
