Oven mikrogelombang (English: microwave oven) is a kitchen appliance that uses microwave radiation to cook or heat food. [Edit] How it works
The main part of the oven mikrogelombang general:
* A magnetron,
* A magnetron control circuit (usually with a microcontroller),
* A waveguide, and
* A cooking space
Mikrogelombang oven works by emitting microwave radiation, usually at a frequency of 2450 MHz (with a wavelength of 12.24 cm), through food. Molecule of water, fat, and sugar in food will absorb energy from the microwaves in a process called dielectric heating. Most molecules are electric dipoles, meaning they have a positive charge on one side and a negative charge on the other, and therefore they will turn on when they try to align themselves with the electric field changes induced by the beam wave micro. This molecular movement creates heat.
Heating by ovens is very effective against water, but not so with the fat, sugar, and ice. Heating mikrogelombang wrong sometimes described as resonance of water molecules, this occurs only at much higher frequencies, at about 10 gigahertz.

According to Devra Davis, a disease that could arise from the use of this computer is obesity and heart problems due to lack of movement. Muscle spasm is also one thing that often happens because over time using a mouse or a wrong position when typing.
Prevention tips: Stretch to relax the muscles in your back and neck that Tegan and buy gelpad on the keyboard.
5. Video Games
This is the fifth elektroni goods that are dangerous to human health. Video games are electronic goods that are now popular worldwide. Because it can be useful as a medium of entertainment. However, we also need to be careful, because if we hold the stick game for too long can cause the hands become red. In his book, Devra Davis called it "The palm of the Playstation". The cause of this happening is because the moisture of human palms sweating. As for the Nintendo Wii game, the most common complaint is the shoulder bone loss because it was too excited in hitting.
Prevention tips:
For those who often play playstation, players should spread his hands with powder before playing. As for fans of the Nintendo Wii, before starting the game, should do stretching first.

computer buying tips
How to buy a computer. First set your computer uses it for what?
Many people are caught up in how to choose a computer, usually people think if the faster the computer the better, what's always been so? The answer is no.
CHOOSE YOUR COMPUTER IN ACCORDANCE WITH usefulness
Okay, for example. If you want to buy a computer for typing, dengarin songs, wrote the film dengarin what type of computer would you buy?
If only for that alone I recommend
TYPE typing COMPUTER AND MULTIMEDIA DENGARIN
Processor: PIII 500 MHz
Memory: 256 MB
Harddisk: 20 GB
DVD-ROM
Monitor: 15 "(need flat2an ga, ga influence)
Price Second reply: USD 1. 400.000
Is this enough? Hmmm this is far from enough.
Why? To know what is enough or we need to know basically ga first.
Analogy
Computers are like Laundry Company.
Processor: Puteran Washing Machine processing (clean clothes)
Cache: Room in Washing Machine that can carry clothes for all processes.
Harddisk: A room containing all the clothes
Memory: A box to put baju2 that will soon be included in the washing machine.
Well now we see the reality on the ground:
1. Processor: How the hell are needed to run Windows programs word.
How to: Open Task Manager (Ctrl + Alt + Del) and look for Processes, and open Windows Word.
Results: To open Windows Word, the CPU in the Processes show number 20, it artiya 20% of our processor, I use P3 500 MHz, meaning that only uses 100 MHz.
If for example the number of processes show greater than 70% and prolonged it just means we have to buy a computer that is higher processor.
2. Memory
Same way like for the processor, and then try to open Windows Word.
Having looked at Task Manager> Processes> Mem Usage then I saw a very small number of 6000 K or 6 MB in use of about 256 MB is available. Whose names are still far from slow
3. Cache
This is usually a rapidly determine whether or not a process other than the program system.
Check: Task Manager> Performance and search for System Cach, Cache system if more than 100 MB is already very good
4. Harddisk
Why should the hard drive if its needs a little banyak2
Documents: Word files vary but if it add up paling2 1 GB
Music: 1 song if rata2 4 MB = 4 GB 1000 songs
Filmu: This is a new eating place, rata2 800 MB if the movie will enter the hard drive inserted into her little aja, anyways it better if taro on cd or dvd aja
Program: Program rata2 small size, which gede2 most like Office = 600 MB, 300 MB Photoshop, Corel Draw about 600 MB, etc.
File System: File Create windowsnya, reserving about 5 GB
Simple game: Game of the flash and other small game, 200 at least 1 GB Game
If ditotal2 20 GB is sufficient.
SECOND ITEM ON THE QUALITY
The most important of view of quality second item is the first time, he can walk or ga.
Usually the second item dikasi warranty 1 week, well for one week a second computer that you turn on and hold aja, kalo replace damaged
Actually rata2 quality goods than the second new stuff is as good as the stuff from early pas ga problematic. In fact, sometimes the second item could be more powerful because it is "experienced" and proven to still run for many years.
Different things just the second new one the same: One year warranty new stuff. Through one year of the new stuff just wrote stuff second.

buy nokia or Blacberry?
many brands of mobile phones in the market of the world, there are kuwalitas low and there is also a high quality, very high quality mobile phone sold in the market is sonny ericson, nokia, aple, and black barry ... if the order to choose?
like blackberry or nokia? Well, Nokia clearly had earned the nickname the phone a million people. This is an indicator that Nokia is the old players in power in the mobile market of Indonesia. Blackberry previously only known as gadgets exclusive property of the executives. Current conditions as if to turn around. Everyone wants a Blackberry.
Blackberry's popularity seems to come together with the boom up as a social network. It seems also accompanied by the misconception that the only BlackBerry that can access Facebook. Whereas the main features of the Blackberry is Push Mail, not for browsing purposes. After a misunderstanding, the Blackberry was a component for a new standard in defining an up-to-date.
This might be one proof of the uniqueness of the Indonesian market. Marketeer magazine cites this with the sentence "Nothing is impossible in Indonesia." How did this happen?
Maybe the Blackberry should be grateful to Friendster that have set up the market by being the initiator of social networks. Friendster has been educating consumers so as not to instill fear of the Internet and social networking with one requirement, more than just a lifestyle.
Connected all the time with a peer is not a priority for the older generation, but for this new generation is what defines Them. We have to know what others are doing and other people should know what we do. If not, then we will lose our presence in the group.
We are very addictive to anything new. Maybe because we are obsessed to be different from the others. Could be this thing that makes the Blackberry chased a lot of people. They want to differentiate from the old group.
Surely this also is not free from rising consumer purchasing ability and the role of vendors in providing a more affordable price scheme. Improving the ability of consumers to make purchases less exclusive than the previous Blackberry but still exclusive because its price is still above the reach of most consumers' mobile phones. How to undo or deal with Such effects?
One way is "Be flexible and jump into the local bandwagon. Do not resist. "But such steps are at risk of eroding the brand characteristics. Echoed on market trends can make the brand lose differentiation Could this happen in the context / other products?
Nothing is impossible in the world. We are what people define us. At least this is a valid formula for a new generation of Indonesian consumers. This may be indeed be a consumer or permanent nature while the effect of a flood of consumer newbie.
What do you think, what really makes the Blackberry on the rise. What about the role of cheap mobile phone manufacturers? Is there any relation with the trend Blackberry telko price war some time ago?
