A Car Bumper Sticker Is A BIG Deal!
In a little of tangential madness, I had been driving to operate today behind vehicle which had a sticker on the bumper saying "I support guns so get free from my way!".
And So I locked my vehicle doorways.
Consider this ---everyday you may drive past 100s or 1000's of individuals moving toward work. A lot of individuals individuals will be behind you without any spot to look except at the bumper. So a sticker is really a potential advertisement for what you are along with a statement about what you believe is essential.
A passive-aggressive sticker with subtle risks of violence against anybody inside your way certainly states something about what you are.
So political peel off car stickers, brand peel off stickers, radio show peel off stickers and then any other sticker the thing is on cars. Actually, just getting or otherwise getting a sticker in your vehicle states something in regards to you.
This means that the humble bumper sticker is really a prime advertising positioning for you personally and what you would like to represent.
Individuals will see what peel off stickers you're considering to use your vehicle (and before 100s or 1000's of individuals) and immediately know just a little in regards to you, what's vital that you you and also possibly even the kind of person you're. It could make sure they are lock their doorways because they overtake you in a rush or provide you with a high-five.
In either case - a vehicle bumper sticker is really a large deal.

Russian civil aviation under attack of laser pointers
The Russian civil aviation has a new enemy - the Russian citizens with common laser pointer. The popular device can be a dangerous weapon when used by criminals. A directed laser beam blinds pilot for a certain time.
On 7 June, when Airbus was 320 with 160 aboard landed at the airport of Rostov-on-Don, the pilot suddenly stabbing pain in his eyes. The crew was professional enough to take the situation under control to time. The plane landed safely.
The investigators of the Interior Ministry of the Rostov region originally assumed that the aircraft can be used under the attack of strong laser beams during festivals, dances and music shows come. The "Dance Party" version was soon rejected it: there is no fun events in town that day.
There was another version available during the investigation - someone used a laser pointer to dazzle the pilot of the aircraft. Unlike laser systems, laser pointers are widely available. The Federal Air Transport Agency said that it had reported a series of such incidents. Some of them occurred in the early summer of 2011.
2nd June. The crew of the Airbus 320 reported during the landing, the pilot was blinded by a laser. On 3 June said another pilot that he was blinded by a green laser. Another pilot of a German airline says the red laser attack near the airport Domodedovo. All these incidents occurred during a week in the airspace of Moscow.
What makes a pilot feel if someone has a laser in his eyes? If it happens, a pilot is not in a position the equipment on board, which is extremely important to control during the landing.
"On landing must pilot to the data of the aircraft movement, which is a lot of information to scan. You need to also monitor the area outside the cockpit, to control the positioning of the aircraft on the runway. Landing a 800-ton aircraft, especially when it is flying over the city - this is a very complicated and responsible to do something, "the pilot of the aircraft under attack, said Dmitry Leontiev.
As for the investigation of the incident in Rostov-on-Don, eyewitnesses said that they have a young man standing on the balcony and showed an intense laser beam in the sky looked.
Mikhail Solovyov, the director of a company produces laser devices, said that laser pointers are usually very powerful units, because people use them at conferences and seminars. Such information may in fact hurt our eyes, said Solovyov.
A laser pointer is in any internet shop for as much as $ 20. The laser device is strong enough to light (100 milliwatts) in a match. More powerful units (300-500 milliwatts) can be overcome distance of ten kilometers. When used on a near object, it can melt plastic and even thin metal.
Green laser pointers are prohibited in the United States. Green is the brightest color to the human eye. There are no such restrictions in Russia, though.
Professor Eugene Latush believe that was the pilot of the aircraft, the landing at the airport in Rostov, were attacked by a 200-milliwatt-pointer. Such pointer with the laser on the crystal with neodymium.
Laser attacks were also reported in Germany is Hamburg. The City Police arrested two teenagers who showed their laser pointers at airplanes, just to have fun.
A laser beam pointed in the eye may result in a spasm of blood vessels in the organ of vision. A pilot may be 10 minutes in such a blind attack. Unpleasant symptoms may disappear in half an hour, but the landing usually takes several minutes.

thermometers
The thermometers, is temperature-measuring device's general name, may the accurate judgment and the survey temperature. The earliest thermometer was (1564~1642) invents in 1593 by Italian scientist Galileo. His first thermometer is an end opens the mouth the glass tube, another end has the walnut big glass bulb. When use heats up first to the glass bulb, then glass tube insertion water. Along with the temperature change, in glass tube's water surface will reciprocate that may determine the temperature according to motion how many change and the temperature height. The thermometer has the expand with heat and contract with cold function, therefore this kind of thermometer, environmental factor's and so on outside the atmosphere intensity of pressure influences is been big, therefore the measuring error is big, the measuring accuracy is not very ideal. Afterward Galileo's student and other scientists, improved repeatedly in this foundation, like the glass tube in reverse, placed the liquid in the tube, glass tube seal and so on. What compared with is prominent is French cloth Leo the thermometer which made in 1659, he glass bulb's volume reduction, and changed the temperature measurement material the mercury, such thermometer has had the present thermometer's embryonic form. Afterward German Holland physicist Warren Hiter when 1709 has invented the alcohol thermometer, when 1714 uses the mercury to replace the ethyl alcohol, takes the survey material the mercury, has made a more precise thermometer, thus caused the thermometer to make the crucial progress. He observed the water boiling heat, Shui Hebing time time the mix temperature, the salt water and the ice mix temperature; After tests repeatedly with approves, finally decides as time certain density's salt water coagulation's temperature 0℉, decides as the pure water coagulation's time temperature 32℉, decides as the standard atmospheric pressure sewer ebullition's temperature 212℉, with ℉ represents the fahrenheit, this is the fahrenheit thermometer.
Now thermometer's type are many, mainly has the petroleum thermometer, the alcohol thermometer, the mercury thermometer, the gas thermometer, the resistance thermometer, the thermo couple thermometer, the solar thermometer and the flash ranging thermometer, the bimetallic thermometer. Although the variety are many, but in the principle basic is consistent, many are using the solid, the liquid, the gas the temperature influence, but expand with heat and contract with cold's phenomenon designs. But along with the technical progress basis use goal's difference, has more and more thermometers to make. Its design's basis has, primitive: Using solid, liquid, gas temperature influence, but expand with heat and contract with cold phenomenon; Constant volume condition: Gas (or vapor) temperature change initiation intensity of pressure change; Pyroelectric effect function: The resistance changes along with the temperature change; Heat radiation influences and so on. In general, all material any physical property, so long as it has monotonously, the remarkable change along with the temperature change, may use for to symbolize that the temperature makes the thermometer. Below introduced in detail in the current society uses the quite widespread several kind of thermometers.
1st, gas thermometer: The multipurpose hydrogen or the helium make the temperature measurement material, because the hydrogen and the helium liquefaction temperature is very low, approaches in the zero absolute temperature, therefore its temperature measurement scope is very broad. This kind of thermometer precision is very high, uses in the precision measurement.
2nd, resistance thermometer: Divides into the metal resistance thermometer and the semiconductor resistance thermometer, is makes according to the resistance value along with temperature change this characteristic. Fine metal and rhodium iron, phosphor bronze alloy and so on metallic thermometer main useful platinum, gold, copper, nickel; The semiconductor thermometer mainly uses the carbon, the germanium and so on. The resistance thermometer easy to operate is reliable, has widely applied. Its measuring range for - 260℃ to 600℃ about.
3rd, thermo couple thermometer: Is in one industry the widespread application temperature-measuring device. Makes using the thermoelectric phenomenon. Two kind of different tinsel weld are forming the working end together, another both sides and the measuring instrument connection, forms the electric circuit. Places the working end is measured the temperature place, when the working end and the free electricity temperature is different, will present the electromotive force, will thus have the electric current to adopt the return route. Through the electricity quantity's survey, the use known place temperature, may determine another temperature. It is suitable between the temperature difference big two materials, uses in the high temperature and the low muddy survey. Some thermo couple can survey reaches as high as 3000℃ the high temperature, some can measure the close zero absolute temperature the low temperature.
4th, high-reading thermometer: Is refers to uses for to survey 500℃ the above temperature thermometer specially, has the flash ranging thermometer, the color temperature to count with the solar thermometer. High-reading thermometer's principle and the structure are quite complex, here no longer discusses. Its measuring range for 500℃ to 3000℃ above, is not suitable for the survey low temperature.
5th, indicator type thermometer: Is the shape according to dial plate's thermometer, also calls the thermometer, uses for to measure the room temperature, is makes with the metal expand with heat and contract with cold principle. It does take the bimetal piece as the bulb, uses for the steering needle. The bimetal piece usually is with the sheet copper and the iron sheet riveting in the same place, and sheet copper in left, iron sheet in right. As a result of the copper expand with heat and contract with cold effect must many which is more obvious than the iron, therefore works as when temperature increment, the sheet copper pulls pulls the iron sheet to be toward right curving, under the indicator in the bimetal piece leads toward right deflects (directional high temperature); Otherwise, the temperature changes low, under the indicator in the bimetal piece leads toward left deflects (directional low temperature).
6th, glass tube thermometer: The glass tube thermometer is realizes the temperature survey using the expand with heat and contract with cold principle. As a result of temperature measurement medium expansion coefficient and boiling point and solidification point difference, therefore our common glass tube thermometer mainly has: Petroleum thermometer, mercury thermometer, red ink thermometer. His merit is the structure is simple, the easy to operate, the measuring accuracy is relatively high, low in price. The shortcoming is surveys the bound and the precision the glass quality and the temperature measurement medium nature limit. And cannot the long-distance range transportation, brittle.
7th, pressure thermometer: The pressure thermometer is uses in the seal vessel's liquid, after the gas either the saturated steam heating, has the volume expansion or the pressure variation achievement measures the signal. Its basic structure is by the temperature bulb, the capillary vessel and the dial gage three parts is composed. The pressure thermometer's merit is the structure is simple, the mechanical strength is high, does not fear the vibration. The low in price, does not need exterior energy. The shortcoming is the temperature measurement scope has the limit, generally in - 80~400℃; The heat los big response time is slow.
8th, mercury thermometer: The mercury thermometer is the inflation type thermometer's one kind, the mercury solidification point is: - 38.87℃, the boiling point is: 356.7℃, uses for to survey 0--150℃ or 500℃ within the scope temperature, it can only take on-the-spot surveillance the measuring appliance. Surveys the temperature with it, not only quite simple direct-viewing, moreover exterior may also avoid the far biography thermometer's error.
From above each kind of thermometer introduced that I believed may at least has a basic understanding to the nowadays existence various types thermometer type as well as their temperature measurement principle. But along with the science gradual progress, I believed that also will have a more advanced thermometer to appear on the market one after another, everybody may anticipate that one day-long arrival.

Protection of computer accessories
Hard disk
Very sensitive to vibration, shipping computers with hard drives can not simply carry them to a place, we must prevent the generation of large shock. Because the hard disk is a complex mechanical device, installed inside the computer, tolerance is limited. A shock will hit the disc head assembly, causing the hard disk drive read-write head scratched the surface, this may damage the disk surface, potentially destroy data on the hard disk (your hard work yo!), May also be more serious damage to the read-write head, so hard disk can not be used permanently. Therefore, we must take the disk read-write head placed in the safe area, before moving; in the process of moving the action must be light; car if you intend to transport it, put it in the best position behind the car on; If by mail, keep it well wrapped up.
Motherboard
Very sensitive to static and deformation, static electricity may eclipse of the motherboard's BIOS chip and data, damage to a variety of interface-based mos transistor gates, which a bad, all the "users" (inserted above it in the card or device) are find each other, because their contact is by bus, the control chip set, the control circuit to coordinate and achieve. So, as far as possible with a soft, anti-static items wrapped board, pay attention to touch it, first touch the conductor, so that the hands of the static release, then gently. In addition, the motherboard may cause the circuit board deformation fracture, component sealing off the line on the motherboard, but close enough, you simply can not be broken. So try not to let the motherboard carry other items on the board above, it is best to carry the box into the motherboard; when installing the motherboard, must be carefully installed in the chassis stable, not the high side of the low side; in insert card, sound card or other card, note the pressure must be moderate and balanced force.
Memory
Very sensitive to overclocking, because the memory has a direct contact with the CPU, so CPU speed is the most difficult to solve the memory bottleneck. The higher the FSB, the faster the work, while the memory because the CPU needs to work in the same FSB, so overclocking the CPU, the memory is consistent with the FSB, is the key to successful overclocking, the most important Once the memory overclocking reach the desired frequency, prone to black, or even heat damage.
CPU
Very sensitive to high temperature and high voltage, although a small CPU fan protection, but with the current increase in consumption of heat generated also increases, so that the CPU's temperature will rise. High temperature tends to occur within the line electron mobility, resulting in frequent computer crashes, reduce the CPU life, high voltage is dangerous, it is easy to burn your CPU. To prevent this from happening, methods of installation of auxiliary cooling fan, cooling fan to keep it clean, regular preventive maintenance; thunder rainy day, do not open the computer and the computer's power plug appropriated; equipped with a regulator; overclocking should try not to raise the core voltage to help with overclocking, because it is worth the candle.
CD-ROM
Very sensitive to dust, vibration and poor CD-ROM, CD-ROM appear slow or does not read the disk to read the disk failure, the problem is mainly due to the laser head. In addition to the laser head itself reasons for the limited life span, the pervasive influence of dust is also a major factor in the life of the laser head. Dust not only affects the quality of the laser head to read the disk and life, the internal drive will also affect the accuracy of the various mechanical components. So to maintain the cleanliness drive is particularly important. General mechanical components for the drive to wipe with a swab of alcohol, but the laser head can not use alcohol and other cleaning agents, can be aligned using the laser blow off the dust bag. From the foregoing, the dust is the laser head of the "killer", but the shock will also bald "Disc", damage to the bald. Therefore, we choose drive earlier, the shock size is also an important reference factor, while in the CD-ROM drive, try to drive the screws tighten on both sides, let the chassis, you can reduce the vibration. CD-ROM is another poor drive the enemy, it will increase the burden of bald servo circuit, accelerated wear of the movement, speed up the aging of the laser tube. Do not know what you believe it or not, is now available in the popular DVCD drive the most dangerous enemy, because it points of light from the design standards and general drive more than a small dot pitch, drive like a nearsighted person reading it as difficult to see tiny small print, maybe someday, "the blind."
Keyboard
Very sensitive to moisture, dust, pull, and now most of the plastic membrane keyboard switch, that switch is constituted by three lines of plastic film, is a hole in the middle of an insulating film, coated on both sides of the thin film metal lines and contacts, corrosive moisture, dust will cause poor contact contact keyboard operation ineffective. Found that the situation should be very carefully open the keyboard cover with brown brush or vacuum cleaner to clear out dirt. Drag and drop easy to make the keyboard line break, so the keyboard is defective. Therefore, we must try to keep the workplace clean and tidy, especially the edge of the keyboard to clean; Do not smoke near the computer; do not eat near the keyboard; Do not drink the cup on the keyboard in the vicinity; do not live to plug keyboard; periodically cleaned with pure alcohol keyboard; when using the keyboard, try not to drag the keyboard; the keyboard when not in use, to cover shield.
Mouse
Very sensitive to dust, light, pull, and now most people are still using the optical mouse, these mice are cheap, easy to use, but the biggest problem is easy to dirty, ball and roller coated with dust on the operation of mechanical components make the mouse not working. In addition, the light will interfere with photocell received signal, will pull the same "tail" fracture, failure of the mouse. Therefore, we must regularly clean the mouse ball and rollers; to make use of special mouse pad, periodically clean the mouse pad, mouse pad to choose different materials according to different detergents, can be used to solve the problem of water is best; avoid the sun open, using the mouse.
Monitor
Very sensitive to temperature, pressure, etc., the display is the interface to communicate with people, but also the entire computer system, power-hungry, is the most easily damaged components. It is very sensitive to impact, temperature, pressure, dust, high brightness and contrast, because the tubes is very precise, instant impact will damage it, such as broken filament prone, crack pipe neck, leakage and other issues; easy to make high-temperature Power switch is damaged, the higher the temperature the more likely the switch breakdown damage, so it's great heat sink; dirt easy to make high-voltage ignition circuit. High brightness and contrast will reduce the life of the phosphor, so that the display a few years will "lose face", the color dark. So we use the computer, try not to frequent startup, shutdown, because the cold tube filament resistance is very small, just getting on the impact of current large machines, often not conducive to protecting the filament power, the other extreme of the tube also affects female; to avoid the sun light, direct exposure to high-intensity electro-optic displays, because they enhance the display of the temperature, accelerated aging CRT monitor, the monitor when not in use drop cloths cover good; such as long-term need, regular power-driven wave, generated high voltage power to prevent a sudden , resulting in burned component failure; monitor should be placed in a place with good ventilation, ventilation holes should not be placed on top of other items.

Very sensitive to vibration, shipping computers with hard drives can not simply carry them to a place, we must prevent the generation of large shock. Because the hard disk is a complex mechanical device, installed inside the computer, tolerance is limited. A shock will hit the disc head assembly, causing the hard disk drive read-write head scratched the surface, this may damage the disk surface, potentially destroy data on the hard disk (your hard work yo!), May also be more serious damage to the read-write head, so hard disk can not be used permanently. Therefore, we must take the disk read-write head placed in the safe area, before moving; in the process of moving the action must be light; car if you intend to transport it, put it in the best position behind the car on; If by mail, keep it well wrapped up.
Motherboard
Very sensitive to static and deformation, static electricity may eclipse of the motherboard's BIOS chip and data, damage to a variety of interface-based mos transistor gates, which a bad, all the "users" (inserted above it in the card or device) are find each other, because their contact is by bus, the control chip set, the control circuit to coordinate and achieve. So, as far as possible with a soft, anti-static items wrapped board, pay attention to touch it, first touch the conductor, so that the hands of the static release, then gently. In addition, the motherboard may cause the circuit board deformation fracture, component sealing off the line on the motherboard, but close enough, you simply can not be broken. So try not to let the motherboard carry other items on the board above, it is best to carry the box into the motherboard; when installing the motherboard, must be carefully installed in the chassis stable, not the high side of the low side; in insert card, sound card or other card, note the pressure must be moderate and balanced force.
Memory
Very sensitive to overclocking, because the memory has a direct contact with the CPU, so CPU speed is the most difficult to solve the memory bottleneck. The higher the FSB, the faster the work, while the memory because the CPU needs to work in the same FSB, so overclocking the CPU, the memory is consistent with the FSB, is the key to successful overclocking, the most important Once the memory overclocking reach the desired frequency, prone to black, or even heat damage.
CPU
Very sensitive to high temperature and high voltage, although a small CPU fan protection, but with the current increase in consumption of heat generated also increases, so that the CPU's temperature will rise. High temperature tends to occur within the line electron mobility, resulting in frequent computer crashes, reduce the CPU life, high voltage is dangerous, it is easy to burn your CPU. To prevent this from happening, methods of installation of auxiliary cooling fan, cooling fan to keep it clean, regular preventive maintenance; thunder rainy day, do not open the computer and the computer's power plug appropriated; equipped with a regulator; overclocking should try not to raise the core voltage to help with overclocking, because it is worth the candle.
CD-ROM
Very sensitive to dust, vibration and poor CD-ROM, CD-ROM appear slow or does not read the disk to read the disk failure, the problem is mainly due to the laser head. In addition to the laser head itself reasons for the limited life span, the pervasive influence of dust is also a major factor in the life of the laser head. Dust not only affects the quality of the laser head to read the disk and life, the internal drive will also affect the accuracy of the various mechanical components.
